Abstract
The invention discloses an elevator brake which comprises an electromagnet, an armature and a brake shoe. The armature is arranged on the electromagnet and is movably connected with the electromagnet, the brake shoe is arranged on the armature and is used for stopping a brake wheel, a cavity is arranged on the side surface, which corresponds to the armature, of the electromagnet, a spring which is butted to the armature is arranged in the cavity, a hole which is communicated with the armature is formed in the surface, which is in contact with the brake wheel, of the brake shoe, a high-precision resistor is mounted in the hole, one end of the high-precision resistor is flush with the brake shoe, the other end of the high-precision resistor is connected with an abrasion detecting module by a wire, the abrasion detecting module is arranged on the outside of the brake and is connected with the brake, data can be fed to an elevator control system by the abrasion detecting module, and an elevator can run and stop under the control of the elevator control system. The elevator brake has the advantages that the elevator can assuredly stop running after the brake shoe is abraded, accordingly, car slipping can be prevented, the brake shoe can be expected to be repaired by professional maintenance staffs, brake shoe adjustment can be carried out again, the safety factor of the elevator can be upgraded, and the safety of passengers can be guaranteed.
Description
Technical field
The present invention relates to elevator field, relate in particular to a kind of elevator brake.
Background technology
Elevator brake is the important safety device of elevator, it safe, be reliably one of key factor of guaranteeing elevator safety operation.It mainly consists of current elevator brake on the market electromagnet, spring, armature and brake rubber block, and its braking principle is: after electromagnet energising, electromagnetic force overcomes spring force and holds armature, drg is opened a sluice gate, and after electromagnet power-off, electromagnetic force disappears, spring force promotes armature, drg band-type brake.But existing drg does not have brake rubber block wear detection function, when brake rubber block wearing and tearing reach after 0.5mm, just cannot band-type brake, elevator still can continue operation, easily causes slipping the dangerous situation generation of car, affects the safety of passenger.
Summary of the invention
Technical matters to be solved by this invention is that a kind of elevator brake that can detect brake rubber block degree of wear is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of elevator brake, comprise electromagnet, be arranged on the armature being flexibly connected with it on electromagnet and be arranged on armature the brake rubber block for brake wheel stop bit, the side that described electromagnet is corresponding with armature is provided with cavity, in cavity, be provided with the spring inconsistent with armature, on the face that described brake rubber block contacts with brake wheel, be provided with the hole communicating with armature, high-accuracy resistance is installed in hole, one end of described high-accuracy resistance flushes with brake rubber block, the other end connects with the abrasion detection module that is arranged on drg outside and be connected with drg by line, this abrasion detection module is controlled by apparatus for controlling elevator.
As preferably, the outer cover of described high-accuracy resistance is equipped with insulation sleeve.
As preferably, between described abrasion detection module and drg, be provided with power light.
Compared with prior art, usefulness of the present invention is: this elevator brake can guarantee that brake rubber block, after wearing and tearing, makes elevator out of service, prevent from slipping car, to wait for that specialized maintenance personnel repair, and adjust lock again, improve the safety factor of elevator, guaranteed passenger safety.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is a kind of elevator brake structural representation of the present invention;
Fig. 2 is the partial enlarged drawing of A in Fig. 1.
In figure: 1, electromagnet; 2, armature; 3, spring; 4, brake rubber block; 5, brake wheel; 6, high-accuracy resistance; 7, insulation sleeve; 8, abrasion detection module; 9, apparatus for controlling elevator; 10, line; 11, indicator lamp.
the specific embodiment:
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
A kind of elevator brake shown in Fig. 1, comprise electromagnet 1, be arranged on the armature 2 being flexibly connected with it on electromagnet 1 and be arranged on armature 2 brake rubber block 4 for brake wheel 5 stop bits, the side that described electromagnet 1 is corresponding with armature 2 is provided with cavity, in cavity, be provided with the spring 3 inconsistent with armature 2, on the face that described brake rubber block 4 contacts with brake wheel 5, be provided with the hole communicating with armature 2, high-accuracy resistance 6 is installed in hole, one end of described high-accuracy resistance 6 flushes with brake rubber block 4, its outer cover is equipped with insulation sleeve 7, be used for guaranteeing high-accuracy resistance 6 and drg insulation, the other end of high-accuracy resistance 6 connects with the abrasion detection module 8 that is arranged on drg outside and is connected with drg by line 10, between described abrasion detection module 8 and drg, be provided with power light 11, for showing the energising situation between abrasion detection module 8 and drg, for the ease of controlling, abrasion detection module 8 is controlled by apparatus for controlling elevator 9, the data of abrasion detection module 8 are fed back to apparatus for controlling elevator 9, by apparatus for controlling elevator 9, control elevator operation and stop again.
Its specific works mode is as follows, and when brake rubber block 4 wearing and tearing, high-accuracy resistance 6 is synchronously wearing and tearing also, thereby resistance value is diminished gradually, and it is large that whole loop current becomes.By brake wear detection module 8 monitoring current threshold value: IA<I≤Im, when electric current reaches Im, apparatus for controlling elevator 9 is cut off the electricity supply, and elevator cannot move.After brake rubber block 4 wearing and tearing, maintainer has keeped in repair at every turn, and brake rubber block 4 all can attenuation, and high-accuracy resistance 6 can also shorten, according to the length of high-accuracy resistance 6, can be by a wearing and tearing minute Pyatyi, to five gears of inductive switch, specific as follows:
During 0 gear, loop disconnects, switch when 1 gear, current threshold: IA<I≤I1, when electric current reaches I1, apparatus for controlling elevator 9 is cut off the electricity supply, elevator cannot move waits for maintenance; After maintenance, switch pushes 2 gears, and amperemeter/ammtr threshold value: I1<I≤I2, by that analogy, is divided into five grades, and when reaching Pyatyi wearing and tearing, drg needs to change.Press drg principle of design, when drg brake rubber block 4 wearing and tearing reach 0.5mm, drg cannot band-type brake, can produce and slip the dangerous phenomenon of car, maintainer, by regulating brake, normally works it again, therefore it is 0.4mm that each grade set brake rubber block abrasion loss, is less than 0.5mm, in safe wear range.
This elevator brake can guarantee that brake rubber block 4, after wearing and tearing, makes elevator out of service, prevents from slipping car, to wait for that specialized maintenance personnel repair, again adjusts lock, has improved the safety factor of elevator, guarantees passenger safety.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
