The assembly structure of the two mounting plates 7 has the advantages of simple structure, easiness in assembly and firmness in connection.
Each of the fixed hooks 32 is a triangular plate-shaped structure with a downward tip, and a hook hole for hooking the end of the cable 5 for hanging is formed through the plate surface of the triangular plate-shaped structure.
The structure of the fixed hook 32 not only has the advantage of high strength of the triangular plate, but also can avoid the contact friction between the fixed hook 32 and the swaying hoisting mooring rope 5 by utilizing the structure of the tip end downwards, and avoid the abrasion to the end part of the hoisting mooring rope 5.
Wherein, the lifting part is four lifting rings 31 distributed on the upper surfaces of four top corners of the rectangular frame structure of the lifting frame 3.
The lifting part is easy to lift by adopting a lifting steel cable 305, and simultaneously, reinforcing ribs at four top corners of the rectangular frame structure are formed, so that the firmness of the whole structure of the hanger 3 is enhanced.
In practice, the hoisting cable 5 is a steel cable 305 having hanging rings at both ends. This allows the hoist rope 5 to be easily hung on the fixed hook 32 and the releasable hook, and helps improve the efficiency of assembling the hoist rope 5.
The anti-overturning lifting tool has the advantages that:
1. the posture is transferred to the thunderbolt for the maintenance test that can be better, avoids laying the in-process and takes place the upset, and the principle is:
the existing lifting appliance adopts a structure that a single side is provided with a releasable hook, so that in the laying process, the single side of the thunder body for the test loses the support instantly when the releasable hook is released, and the thunder body is integrally inclined to the single side where the releasable hook is located and overturns.
After the product is adopted, the structure that the installation positions of the adjacent 2 fixed hooks connected by the cables for hoisting and the installation position of the releasable hook are opposite to each other is adopted; therefore, in the moment of releasing, the whole body of the mine for the test can form support through the fixed hook on the side and the cable for hanging in the two sides of the length direction, so that the condition that the single side of the mine for the test loses support instantly to cause overturning is avoided, and the laying posture can be better kept.
2. And can also play a better protection role.
During the falling process of the test detonator during the laying: the friction force can be generated between the surface of the mine body of the hoisting cable rope and the surface of the mine body of the test mine body, and the fixed hooks and the releasable hooks of the adjacent 2 hoisting cable ropes are arranged in a staggered manner, so that the same-direction friction force is applied to the surfaces of two sides (in the length direction) of the mine body of the test mine body, the phenomenon that the same-direction friction force acts on the same side to generate larger friction (damage) and cause overturning is avoided, and a better protection effect is achieved on the test mine body.
3. Simple structure, the implementation degree of difficulty is little, easily makes and uses.
The above is only a preferred embodiment of the present invention, and it should be noted that several modifications and improvements made by those skilled in the art without departing from the technical solution should also be considered as falling within the scope of the claims.
