Description

A kind of hoisting crane suspension hook anti-drop device

Technical field

The utility model belongs to hoisting crane technical field, is specifically related to a kind of anti-drop device, particularly a kind of hoisting crane suspension hook anti-drop device.

Background technology

Load hook is when lifting weight, often there is weight obscission, cause the damage of weight, weight is caused to fall from height in the air, cause the damage of weight or equipment, casualty accident is caused time serious, at present, many employings arrange an Elastic buckle in the end of suspension hook hook body, lifted weight is avoided to come off, but, this mode not only needs larger elastic force to prevent to come off, and this structure causes space in hook body to reduce, lifted weight is limited to, when taking out weight, also very inconvenient, although some anti-drop device good anti-drop effect, but complex structure mostly, difficulty of processing is large, cost is higher, therefore, a kind of simplicity of design is provided, the hoisting crane suspension hook anti-drop device that easy to use, good economy performance, slip-off preventing are effective is necessary.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of simplicity of design, the hoisting crane suspension hook anti-drop device that easy to use, good economy performance, slip-off preventing are effective.

The purpose of this utility model is achieved in that a kind of hoisting crane suspension hook anti-drop device, it comprises hook body, the top of described hook body offers hook on hole, the neck of described hook body is provided with welding hook, the bill position of described hook body is provided with welding block, described welding block is connected with turret A by axle A, described turret A is connected with spring body, the other end of described spring body is connected with turret B, described turret B is provided with axle B, and described axle B is arranged in welding hook.

The connection mode of described welding block and turret A is hinged.

The connection mode of described turret A and spring body, spring body and turret B is for being fixedly connected with.

Described hook body with weld hook, hook body and welding block connection mode for welding.

The beneficial effects of the utility model: the utility model welds a welding hook at the neck of hook body, a welding block is welded outside the bill of hook body, on welding block, be hinged with turret A by axle A simultaneously, when needs prevent weight rope, turret B is taken off from welding hook under the elastic reaction of spring body with axle B, weight rope is placed on after in hook body, rotate turret A and axle A, being hung over axle B by turret B welds in hook, and actv. prevents slip-off preventing effect of the present utility model; The utility model also has the advantage of simplicity of design, easy to use, good economy performance simultaneously.
