Abstract
The utility model relates to a tower crane hook, belonging to the crane mechanical device parts technical field, comprising an upper pulley, an upper pulley clamping plate, a lower pulley, a lower pulley clamping plate, a reflection film, a hook head and a hooking-off prevention protection claw. The lower pulleys are mounted at the two sides of the upper part between the lower pulley clamping plates and the hook head is arranged at the lower part and the hooking-off prevention protection claw is arranged on the hook head. The upper pulley clamping plate and the upper pulley are mounted on the lower pulley clamping plate between the lower pulleys. Handles are mounted on the two side surfaces of the lower pulley clamping plate and the reflection film is coated on the outer surface of the lower pulley clamping plate. The tower crane hook uses the reflection film on the lower pulley clamping plate and the hooking-off prevention protection claw on the hook head to solves the problems of the prior tower crane that: the operation staff can not clearly observe the operation state of the hook when the tower crane operates at night and the other article is hung on the hook by error; the prior hook has no hooking-off prevention protection device so that the safety hidden trouble is generated during the production process. The tower crane hook has features of simple structure, safe and reliable use and strong practicability.
Description
Technical field:
The utility model relates to a kind of tower machine suspension hook, belongs to lifting equipment parts technical field.
Background technology:
Being used for hanging the suspension hook of fastening the weight wire rope sling, is the vitals on the lifting equipment such as tower machine, and the quality of its safety performance directly influences the safe in utilization and operating personnel's of weight-lifting equipment personal safety.During present weight-lifting equipment operation, particularly night light dark, under the caliginous situation, operating personnel in the operator's compartment of tower machine top can't clearly observe the service condition of below suspension hook, hang other objects and suspension hook because of suspension hook mistake and take place tiltedly to draw and askewly hang caused accident and happen occasionally, cause damage for the property of production unit; On the other hand, present suspension hook does not have the lock hook device that prevents to fasten the weight hoist cable is set, and stays potential safety hazard to safety in production equally.
Summary of the invention:
The purpose of this utility model is: provide a kind of lifting hook pulley both sides clamping plate to be provided with reflective devices, and the suspension hook gib head is provided with the lock hook device; When working night to solve, the operating personnel of tower machine top operator's compartment can not clearly observe suspension hook operation situation, cause suspension hook to hang other objects and suspension hook by mistake the askew caused accident of hanging takes place tiltedly to draw, and existing suspension hook is not provided with the lock hook device is installed, and stays the tower machine suspension hook of potential problem to safety in production.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of tower machine suspension hook, it is protected pawl and is constituted by top sheave, top sheave clamping plate, lower sheave, lower sheave clamping plate, suspension hook gib head, lock hook, it is characterized in that: the both sides, top between two lower sheave clamping plate are equipped with lower sheave by bearing pin, the bottom is equipped with the suspension hook gib head by bearing pin, and the suspension hook gib head is provided with lock hook and protects pawl; Be fixed with two top sheave clamping plate by bolt on the lower sheave clamping plate between two lower sheaves, by bearing pin top sheave be installed between two top sheave clamping plate; The two sides of lower sheave clamping plate are equipped with handle, be coated with on the outside face of lower sheave clamping plate reflective membrane is housed.
It is L-shaped that pawl is protected in described lock hook, and its bending corner is provided with pin shaft hole, and by the opening part of movable set at the suspension hook gib head of shipping and reselling on another market.
The utility model beneficial effect compared with prior art is:
This tower machine suspension hook is by being coated with the reflective membrane that is contained on the lower sheave clamping plate outside face, under the irradiation of night lights, suspension hook lower sheave clamping plate can be reflective, make when working the night of light difference, staff in the operator's compartment of tower machine top can clearly observe the service condition of below suspension hook, increased the safety that the tower machine is hung article night, reduced suspension hook and hung other objects by mistake and the askew probability that hangs accident takes place tiltedly to draw at night.Protect pawl by the lock hook that is arranged on the suspension hook gib head in addition, can effectively prevent when operation, the problem that causes any property loss to unit in charge of construction because of rope breaks away from the safety misadventure that hook is caused.And have characteristics simple in structure, safe and reliable, practical.
Description of drawings:
Accompanying drawing is a kind of structural representation of tower machine suspension hook.
Among the figure: 1, top sheave, 2, bearing pin, 3, the top sheave clamping plate, 4, lower sheave, 5, handle, 6, the lower sheave clamping plate, 7, reflective membrane, 8, the suspension hook gib head, 9, lock hook protects pawl, 10, ship and resell on another market.
The specific embodiment:
This tower machine suspension hook is by top sheave 1, bearing pin 2, top sheave clamping plate 3, lower sheave 4, handle 5, and lower sheave clamping plate 6, reflective membrane 7, suspension hook gib head 8, lock hook are protected pawl 9 and constituted.Both sides, top between two lower sheave clamping plate 6 are equipped with lower sheave 4 by bearing pin 2, and the bottom is equipped with suspension hook gib head 8 by bearing pin 2, and suspension hook gib head 8 is provided with lock hook and protects pawl 9.Be fixed with between 3, two top sheave clamping plate 3 of two top sheave clamping plate by bolt on the lower sheave clamping plate 6 between two lower sheaves 4 and top sheave 1 be installed by bearing pin 2.The two sides of lower sheave clamping plate 6 are equipped with handle 5, and the staff controls suspension hook when being used for the hook operation, are coated with on the outside face of lower sheave clamping plate 6 reflective membrane 7 is housed.It is L-shaped that pawl 9 is protected in described lock hook, Metallic rod bending by strip forms for 90 °, one end of its bending is the gravity end, the other end is a sealing end, the bending corner is provided with pin shaft hole, gravity end length is greater than sealing end, and by the opening part (referring to accompanying drawing) of 10 movable sets at suspension hook gib head 8 of shipping and reselling on another market.
During this tower machine suspension hook work, the gravity end that the staff at first protects lock hook pawl 9 upwards lifts, to protect pawl 9 as a whole because of lock hook, sealing end was opened downwards naturally when the gravity end upwards lifted, thereby the opening of suspension hook gib head 8 is opened, the rope cover that with bolt is weight at this moment hangs on the suspension hook gib head 8, unclamp the gravity end that pawl 9 is protected in lock hook then, the sealing end that pawl 9 is protected in lock hook upwards lifts under the action of gravity of gravity end, the opening of suspension hook gib head 8 is blocked, reach the purpose that prevents rope disengaging suspension hook gib head 8.
When working at night operation, irradiation by lighting scene, the reflective membrane 7 of application on the outside face of lower sheave clamping plate 6 can be reflective, the operating personnel can be more clearly visible the control position of suspension hook, thereby increase the safety of hanging weight night, reduced suspension hook and hung other objects by mistake and the askew probability that hangs accident takes place tiltedly to draw at night.
