With the development of production and the progress of technology, the application requirements of various industries on the crane are higher and higher, the variety of the hoisted objects is more and more, and the weight of the objects is also larger and more. The straight handle double hooks (lifting hooks) are connected with a lifting appliance through a pulling plate device to lift hundreds of tons of objects until the working condition of thousands of tons of objects is ubiquitous.

When an object is hoisted, the object needs to be manually hooked and unhooked, so that the operation is inconvenient, time-consuming, low in efficiency and unsafe.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the technical problems of low efficiency and poor safety of manual hooking and unhooking during the traditional object hoisting are solved.

The utility model provides an automatic hang and take off hoist device, include:

the hoisting structure is provided with a bracket, and the bracket is provided with a plurality of clamping tongues which are uniformly distributed;

the lifting structure is arranged at the top of a lifted object, and the upper end of the lifting structure is provided with a clamping plate which is used for clamping the clamping tongue;

and the unhooking device acts on the clamping tongue and is used for separating the clamping tongue from the clamping plate.

When the hoisted object needs to be hoisted, the hoisting structure is lowered, the clamping tongue is clamped with the clamping plate, and the fixed connection between the hoisting structure and the hoisting structure is realized; when the hoisted object needs to be placed, the unhooking device pushes the clamping tongue to separate the clamping tongue from the clamping plate, so that the hoisting structure is separated from the hoisting structure; the utility model is not only easy to operate, improved work efficiency moreover to the security has been improved.

Furthermore, the support is provided with a plurality of branch pipes which are uniformly distributed, and the clamping tongues are inserted in the branch pipes and connected through springs arranged in the branch pipes. The design realizes the elastic connection of the clamping tongue and the branch pipe, and realizes the clamping connection or the separation of the clamping tongue and the clamping plate through the elasticity of the clamping tongue, and the structure is simple.

Furthermore, a limiting plate is arranged at one end, located outside the support, of the clamping tongue. The limiting plate is arranged to control the distance of the clamping tongue extending into the support.

Furthermore, a first inclined plane is arranged at the lower end of the clamping tongue. Under the effect of the first inclined plane direction, the clamping tongue and the clamping plate are clamped more smoothly.

Furthermore, the unhooking device comprises an annular sliding block used for being clamped with the first inclined plane, the lifting structure is provided with a step, the sliding block freely slides between the clamping plate and the step, and a second inclined plane is arranged at the lower end of the sliding block. When the hoisting structure needs to be separated from the hoisting structure, the hoisting structure moves downwards to enable the clamping tongue to be clamped with the sliding block, the clamping tongue retracts under the action of the first inclined surface, the hoisting structure continues to move downwards, the clamping tongue moves to the position below the sliding block, the clamping tongue pops out, then the hoisting structure is pulled up, the clamping tongue drives the sliding block to move upwards, when the sliding block is connected with the clamping plate, the clamping tongue retracts under the action of the second inclined surface, the hoisting structure continues to be pulled up, the clamping tongue moves to the position above the clamping plate to pop out, and separation of the clamping tongue and the clamping plate is achieved; the whole process is simple and convenient to operate.

Further, the outer diameter of the sliding block is larger than or equal to that of the clamping plate. By the design, the clamping tongue and the clamping plate can be separated more smoothly.

Further, the upper end of the clamping plate is hemispherical. The clamping tongue and the clamping plate are clamped more smoothly by the arrangement.
