in order to achieve the technical purpose and the technical effect, the utility model is realized by the following technical scheme:

the utility model provides a hoist anticollision detection device, includes the support column, and the support column upper end is provided with the crossbeam, is provided with running gear on the crossbeam, and the running gear lower extreme is connected with the hoist, and the hoist lower extreme is connected with the hoisting block that has the lifting hook through wire rope, the up end of hoisting block is provided with a plurality of hinge piece with the lower terminal surface equiangular degree of hoist, has the extensible member between the corresponding hinge piece from top to bottom, be provided with corresponding distance sensor on the hoisting block outer wall.

Further, the number of the hinge blocks is not less than three.

Further, the telescopic piece comprises connecting blocks, cross rods are arranged between the connecting blocks, and the connecting blocks are hinged with the upper end face of the lifting block and the hinge block of the lower end face of the crane respectively.

Further, the lower end face of the crane and the upper end face of the hoisting block are positioned on the outer side of the steel wire rope and are sleeved with telescopic sleeves.

Further, anti-collision pads are arranged on the inner walls of the two ends of the supporting column.

Working principle and beneficial effect: when a heavy object is transported, the heavy object is moved to the position right above the heavy object through a travelling mechanism, the crane lays down the lifting block and the lifting hook through the steel wire rope, the distance between the crane and the lifting block is increased along with the crane laying down of the steel wire rope, at the moment, the telescopic parts stretch and drag along with the descending of the lifting block, the telescopic parts arranged at equal angles limit the front, back, left and right positions of the lifting block in the descending process of the lifting block, and when the travelling mechanism drives the crane, the lifting block and the heavy object to move, the telescopic parts can drag and limit the lifting block in multiple directions until the heavy object is stably transported to a proper position; the telescopic parts hinged with the hinged blocks on the crane and the lifting block can limit the front, back, left and right positions of the lifting block when the lifting block descends, ascends or moves along with the travelling mechanism, so that the lifting block is prevented from shaking along with a steel wire rope, collision loss is avoided when the lifting block lifts the weight, and the potential safety hazard of personnel is greatly reduced.

Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1-5, a crane anticollision detection device comprises a support column 1, wherein the upper end of the support column 1 is provided with a cross beam 2, a travelling mechanism 3 is arranged on the cross beam 2, the lower end of the travelling mechanism 3 is connected with a crane 4, the lower end of the crane 4 is connected with a lifting block 5 with a lifting hook 6 through a steel wire rope 13, the upper end face of the lifting block 5 and the lower end face of the crane 4 are provided with a plurality of hinging blocks 7 at equal angles, telescopic parts are hinged between the upper and lower corresponding hinging blocks 7, and the outer wall of the lifting block 5 is provided with a corresponding distance sensor 12.

When transporting the heavy object, remove directly over the heavy object through running gear 3, hoist 4 puts down hoist block 5 and lifting hook 6 through wire rope 13 and fixes the heavy object, along with hoist 4 puts down wire rope 13, make the distance between hoist 4 and the hoist block 5 increase, the extensible member stretches traction along with hoist block 4's decline and carries out this moment, the extensible member that the angle set up is spacing to hoist block 5 front and back left and right sides position at hoist block 5 in-process that hoist block 5 descends, running gear 3 moves through driving hoist 4, hoist block 5 and heavy object, the extensible member can pull spacingly to hoist block 5 a plurality of positions, until with the stable transportation of heavy object suitable position.
