Application examples 1
Below, the testing process of the balance coefficient of elevator detecting device 100 of first preferred embodiment is described.
During the balance coefficient of elevator test, lift car M1 and counterweight M2 are successively moved to the top position of hoistway, this balance coefficient of elevator detecting device 100 is installed.
For example, at first the lift car zero load is moved to the top position of hoistway, the conduct of above car, choosing cage side detects the length of cable of target, with can be safely, be convenient to operatively install this balance coefficient of elevator detecting device 100 and be as the criterion.Four groups of rope slings 13 of two first fixture blocks 11 are alignd with corresponding four steel ropes 1 respectively; Fastening assembly 14 is installed,, two first fixture blocks is applied gripping power through the fastener 142 that tights a bolt; To clamp steel rope 1 respectively, realize the relative fixed of two first fixture blocks 11 and steel rope 1.Subsequently, cable traction device 40 is installed, the base 401 of cable traction device 40 is clamped on one of them first fixture block 11.The position of distance first fixture block suitable distance below first fixture block then; Four groups of rope slings 13 of two second fixture blocks 12 are alignd with corresponding four steel ropes 1 respectively; Fastening assembly 14 is installed,, two second fixture blocks is applied gripping power through the fastener 142 that tights a bolt; To clamp steel rope 1, realize the relative fixed of two second fixture blocks 12 and steel rope 1.Rope assembly 20 then is installed.Rope anchor 201 is fixedly mounted on another first fixture block that does not have clamping cable traction device 40, between rope anchor 201 and the cable traction device 40 across steel rope 1.With rope guide 202 across being installed on two second fixture blocks 12.One end of rope 203 is fixed in rope anchor 201, and the other end passes the pulley on the rope guide 202, is fastenedly connected with the tractive unit 402 of cable traction device 40.So far, as shown in Figure 4, accomplish the installation of this balance coefficient of elevator detecting device 100.At this moment, the steel rope that is clipped between first fixture block and second fixture block is above-mentioned as the length of cable that detects target.
Subsequently, operation rope tractor 40 slowly promotes tractive unit 402, tractive unit 402 tractions and tension rope 203, and the steel rope 1 between first fixture block and second fixture block is in the state of not stressing.After this, continue to promote tractive unit 402, then car 70 with on move, in the process that car 70 slowly moves at the uniform velocity, the value F1 on the record force indicator 50 utilizes conventional means just can obtain the dynamic cage side weight of elevator G1 by F1.End subsequently promotes, and makes car static, the value F2 on the record force indicator 50 this moment, the cage side weight G2 in the time of just can obtaining elevator static state by F2 through conventional means equally.
In like manner; When measuring the weight of counterweight 80 sides; Also be at first counterweight 80 to be moved to the top position of hoistway, above counterweight 80, choose the length of cable that the conduct of heavy side is detected target, with can be safely, be convenient to operatively install this balance coefficient of elevator detecting device 100 and be as the criterion.After repeating the installation process of above-mentioned balance coefficient of elevator detecting device 100, operation rope tractor 40 slowly promotes tractive unit 402, and the steel rope 1 between first fixture block and second fixture block is in the state of not stressing.After this, continue to promote tractive unit 402, then counterweight 80 with on move, in the process that counterweight 80 slowly moves at the uniform velocity, the value F3 on the record force indicator 50 utilizes conventional means just can obtain the dynamic counterweight of the elevator amount of stressing W1 by F3.End subsequently promotes, and makes counterweight static, and the value F4 on the record force indicator 50 this moment is same, the counterweight amount of the stressing W2 when utilizing conventional means just can obtain elevator static state by F4.
Subsequently, the counterweight amount of stressing W1, W2 when cage side weight G1, G2 and the elevator with elevator when dynamic, static is dynamic, static are updated among equilibrium factor algorithmic formula K=(W-G)/Q; K is an equilibrium factor; W is a cage side weight, and G is the counterweight amount of stressing, and Q is the nominal payload of elevator.Thereby, obtain dynamical equilibrium COEFFICIENT K 1=(the W1-G1)/Q of elevator and static balancing COEFFICIENT K 2=(the W2-G2)/Q of elevator.
