Abstract
The utility model relates to an anti-explosion chain block which comprises a lifting hook, a lifting wall plate, a lifting chain and a grab hook, wherein the lifting wall plate is connected with the lifting hook through a lifting hook frame; the lifting chain and the grab hook are connected with the lifting wall plate; and one end of the lifting chain is fixedly connected with the lifting hook frame. The middle part of the lifting hook frame of the anti-explosion chain block provided by the utility model is directly connected with the lifting hook, one underside end is connected with the wall plate while the other end is connected with the lifting chain, so that the gravity is dispersed, 50% of bearing force of the wall plate is reduced, the forces at two ends of the lifting hook frame are basically balanced, the stress of the lifting hook is not influenced and the service life of the chain block is effectively prolonged.
Description
Technical field
The utility model relates to a kind of explosion-proof chain block.
Background technology
The little heavy-duty hoisting equipment that explosion-proof chain block lifts by crane, carries cargo as a kind of short range, with it safe and reliable, flexibly advantage such as convenient, durable in use have in factory, mine, warehouse etc. the field of flammable explosive gas resultant use widely.Be rotationally connected through pearl between the suspension hook of present existing chain block and the hanging beam; The direct frame of hanging beam is between two wallboards, and an end of hoisting chain hangs between two wallboards through chain sling plate and a pin, when carrying weight; Gravity has all dropped on to be had only on the thick wallboard of 4-5mm; And wallboard is the carrier of all movements, in a single day stressed excessive deformation of wallboard or damage, and whole chain block will be scrapped.
The utility model content
The utility model technical matters to be solved provides a kind of simple in structure, easy to operate and can effectively prolong the explosion-proof chain block explosion-proof chain block in service life.
The utility model adopts following technical scheme:
The utility model comprises suspension hook, the lifting wallboard that is connected with suspension hook through the suspension hook frame and hoisting chain and the lifting hook that is connected with the lifting wallboard, and an end of described hoisting chain is captiveed joint with the suspension hook frame.
The utility model good effect is following:
The centre portion of the suspension hook frame of the utility model chain block and suspension hook direct connection, below an end be connected on the wallboard, the other end has then connected hoisting chain; Like this; Disperse gravity, reduced the bearing capacity of wallboard 50%, hang the strength basic equalization at framework two ends; Can not impact, effectively prolong the service life of chain block the stressed of suspension hook.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
In the accompanying drawings: 1 suspension hook, 2 suspension hook framves, 3 lifting wallboards, 4 hoisting chains, 5 lifting hooks.
The specific embodiment
Shown in accompanying drawing 1, the utility model comprises suspension hook 1, through lifting wallboard 3 and hoisting chain 4 that is connected with lifting wallboard 3 and lifting hook 5 that suspension hook frame 2 is connected with suspension hook 1, and an end of described hoisting chain 4 is captiveed joint with suspension hook frame 2.The centre portion of the suspension hook frame 2 of the utility model chain block and suspension hook 1 direct connection, below an end be connected on the lifting wallboard 3, the other end has then connected hoisting chain 4; Like this; Disperse gravity, reduced 50% bearing capacity of lifting wallboard 3, hang the strength basic equalization at framework 2 two ends; Can not impact, effectively prolong the service life of chain block the stressed of suspension hook 1.The utility model is simple in structure, and is easy to use.
