Abstract
The invention belongs to the field of machine manufacturing of cranes, and particularly relates to a lifting hook and a crane provided with the lifting hook. The lifting hook is characterized in that a groove is formed in a lower position, relative to a baffle installation base, of a lifting hook body; the lifting hook further comprises a baffle which consists of a pivot end and a free end, wherein the pivot end is pivoted with the baffle installation base, the pivot end is hollow and is internally provided with parallel channels, a backstop bump is arranged at an opening of each channel, and at least one spring is arranged at the pivot end close to the baffle installation base; one end of the free end is sleeved with the pivot end and is connected with the springs, locking baffles are arranged on both sides of the free end and are matched with the parallel channels, and a through hole is formed in the other end of the free end; a slot is formed outside the hook part of the lifting hook body and is matched with the through hole in the free end. The lifting hook provided by the invention has the advantages that the lifting hook is novel in concept and compact and reasonable in structure, and the free end of the baffle can slide in the pivot end; the baffle has the anti-skid function; a lifting rope is convenient to be hoisted into the lifting hook or taken from the lifting hook, so that the time and labor are saved, and the work efficiency is improved.
Description
Technical field
The invention belongs to hoisting crane mechanical manufacturing field, relate in particular to a kind of suspension hook and there is this suspension hook
Hoisting crane.
Background technology
In prior art, conventional suspension hook has the anti-drop function that prevents that lifting rope from deviating from from holding the inner space of lifting rope.Opening one side of the suspension hook body coupling end of suspension hook has been installed baffle plate mount pad, baffle plate comprises hub switch side and the free end being oppositely arranged, hub switch side is arranged on baffle plate mount pad by bearing pin, free end can rotate around bearing pin, torsion spring acts on respectively suspension hook body and baffle plate, and under the effect of torsion spring, the free end of baffle plate is close on the inwall of suspension hook body, thereby make baffle plate sealing opening, prevent that lifting rope from breaking off relations.Defect is, because baffle plate is close on the inwall of suspension hook body, when taking out or change lifting rope, need artificially baffle plate to be depressed towards the direction of the inner space of suspension hook body, also when taking out or packing lifting rope into, in order to open the opening of suspension hook, need apply the twisting resistance that a power applies baffle plate with opposing torsion spring to baffle plate; Lifting rope is heavy, needs two people to operate just and can complete, waste time and energy, and inefficiency.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of suspension hook and there is the hoisting crane of this suspension hook, suspension hook is simple in structure, not only there is anti-drop function, and lifting rope packs suspension hook into or convenient and swift, time saving and energy saving when suspension hook takes off, increase work efficiency.
A suspension hook, comprises suspension hook body, holds inner space and the opening of lifting rope; Baffle plate mount pad, is positioned at one end of suspension hook body upper shed, is characterized in that described suspension hook body has a groove with respect to the lower side position of baffle plate mount pad; This suspension hook also comprises baffle plate, and described baffle plate is comprised of hub switch side and free end, hub switch side and the pivot joint of baffle plate mount pad, and hub switch side is hollow form, inside establishes parallel channel, and groove channel port is established stopper protrusion, and at least one spring is established near baffle plate mount pad end in hub switch side; Free-ended one end is sleeved in hub switch side, is connected with spring, and stop block is established in both sides, and stop block matches with parallel channel, and the other end has through hole; The hook portion outside of described suspension hook body is provided with a draw-in groove, matches with free-ended through hole.
The present invention further improves, and the length of described parallel channel is that hub switch side is to 1/3 of suspension hook body distal-most end distance.
The present invention further improves, and described through hole is rectangle, and width is greater than the diameter of section of suspension hook body.
The present invention further improves, and described draw-in groove cross section is square, and draw-in groove is offered angle horizontal by 60 ° of angles.
The present invention also provides a kind of hoisting crane, and this hoisting crane comprises suspension hook, the suspension hook that described suspension hook is the invention described above.
Compared with prior art, advantage is: this suspension hook is novel, and structure letter gathers, rationally, the free end of baffle plate can slide in hub switch side, and baffle plate has anti-drop function, and lifting rope packs suspension hook into or be convenient and swift when suspension hook takes off, time saving and energy saving, increase work efficiency.

In figure: 1-suspension hook body, 2-baffle plate mount pad, 3-baffle plate, 4-hub switch side, 5-free end, 6-through hole, 7-draw-in groove, 8-groove, 9-spring, 10-parallel channel, 11-stopper protrusion, 12-stop block.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is further described.
By Fig. 1,2, can be found out, a kind of suspension hook, comprises suspension hook body 1, holds inner space and the opening of lifting rope; Baffle plate mount pad 2, is positioned at one end of suspension hook body upper shed; Suspension hook body has a groove 8 with respect to the lower side position of baffle plate mount pad; This suspension hook of this suspension hook also comprises baffle plate 3, and described baffle plate is comprised of hub switch side 4 and free end 5, hub switch side and the pivot joint of baffle plate mount pad, hub switch side is hollow form, inside establish parallel channel 10, groove channel port is established stopper protrusion 11, and two springs 9 are established near baffle plate mount pad end in hub switch side; Free-ended one end is sleeved in hub switch side, is connected with spring, and stop block 12 is established in both sides, and stop block matches with parallel channel, and the other end has rectangular through holes 6, and the width of through hole is greater than the diameter of section of suspension hook body; The hook portion outside of described suspension hook body is provided with a draw-in groove 7, and draw-in groove cross section is square, and draw-in groove is offered angle horizontal by 60 ° of angles, matches with free-ended rectangular through holes.
By Fig. 2,3, can be found out, the length of parallel channel 10 is that hub switch side 4 is to 1/3 of suspension hook body 1 distal-most end distance.
During work, as shown in Figure 1, free end, due to the pulling force of spring, fastens the head draw-in groove of free-ended through hole and suspension hook body, and lifting rope packs suspension hook into, seals the opening of suspension hook, has anti-avulsion effect; As shown in Figure 2, free end around the opposite side to suspension hook body, fits the bottom of hub switch side and groove from hook portion, and now, lifting rope is easy to take out.
A hoisting crane, this hoisting crane comprises suspension hook, the suspension hook of this hoisting crane adopts the suspension hook of the invention described above.
