Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a regulating and positioning device for cranes. Background Art

[0002] Cranes are multi-action lifting machines that can lift and carry heavy objects vertically and horizontally within a certain range. The working characteristics of lifting equipment are intermittent movements, that is, the corresponding mechanisms of taking materials, moving, unloading, etc. work alternately in one working cycle. The development and use of cranes in the market are becoming more and more extensive.

[0003] Most of the existing cranes use wire ropes for lifting, and the wire ropes will swing when they are retracted and released, causing the slings below the wire ropes to shift and deviate from the central axis of the slings, and then the hook cannot be accurately raised or lowered to the required position. In addition, during the use of the wire ropes, dirt is easily adhered to the wire ropes, and the dirt will increase the friction between the wire ropes and the pulleys, thereby accelerating the wear of the wire ropes and reducing the service life of the wire ropes. For this reason, we propose a control and positioning device for cranes. Utility Model Content

[0004] The purpose of the utility model is to provide a device for controlling and positioning a crane, so as to solve the problems raised in the above-mentioned background technology that the wire rope will swing when it is retracted and released, and then the hook cannot be accurately raised or lowered to the required position, and dirt sticking to the wire rope will increase the friction between the wire rope and the pulley.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for controlling and positioning a crane, comprising a gantry and a cleaning box, wherein the cleaning box is located in the inner cavity of the gantry, a sling device is slidably connected to the top of the inner cavity of the gantry, a positioning box is fixedly connected to the bottom of the sling device, springs are fixedly connected to the left and right side walls of the inner cavity of the positioning box, a mounting plate is fixedly connected to the end of the spring, a damping block is fixedly connected to the middle of the left and right side walls of the mounting plate, a connecting rod is fixedly connected to the inner wall of the mounting plate, and a sleeve is fixedly connected to the end of the connecting rod.

[0006] As a further description of the above technical solution:

[0007] The inner cavity top and the inner cavity bottom of the cleaning box are provided with grooves, and the inner cavity of the groove is rotatably connected with a cylinder.

[0008] As a further description of the above technical solution:

[0009] A ball is rotatably connected between the groove and the cylinder.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the cylinder is fixedly connected with bristles, and the outer wall of the cylinder is fixedly connected with a rack around its periphery.

[0012] As a further description of the above technical solution:

[0013] A motor is fixedly connected to the left side of the inner cavity bottom of the cleaning box.

[0014] As a further description of the above technical solution:

[0015] A gear is fixedly connected to the end of the power output shaft of the motor, and the gear meshes with the rack to rotate.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The control and positioning device for cranes is used to put a sleeve on the wire rope so that the wire rope will drive the sleeve to shake when it shakes, and then the shaking of the sleeve is reduced by a spring and a damping block, so that the wire rope gradually remains stable, thereby avoiding the shaking of the hoisting device, so that the hoisting device can be accurately lifted to the desired position, thereby improving the lifting effect.

[0018] 2. The control and positioning device for cranes drives the gear to rotate through a motor, so that the gear drives the rack to move, and the cylinder rotates through the cooperation of the ball. The rotation of the cylinder causes the bristles inside the cylinder to continuously clean the wire rope, and then sweep away the stains on the wire rope. Finally, through the retraction and release of the wire rope itself, the bristles can clean different positions of the wire rope, thereby removing dirt on the wire rope, reducing the wear of the wire rope, and increasing the service life of the wire rope.
