Crane hoisting anti-collision structure

Abstract

The utility model relates to a crane hoisting anti-collision structure which comprises a bottom plate, two supporting plates are fixedly installed on the top of the bottom plate, and anti-collision structures are arranged in the two supporting plates. According to the crane hoisting anti-collision structure, by arranging the anti-collision structure, when a buffer block is impacted by hoisted goods, the buffer block is pressed downwards to enable two cams to rotate, the two cams drive a rotating rod to rotate, and the rotating rod can rotate reversely due to the fact that the rotating rod is subjected to torsion of a torsion spring, so that the buffer block counteracts part of impact, and first shock absorption is conducted; then a rotating rod compresses a spring through a gear, a rack and sliding blocks, due to the reset effect of the spring, a part of buffering force can be counteracted, so that second shock absorption is achieved, the two sliding blocks move away from each other to drive a moving plate to press downwards through a moving rod, and third shock absorption is conducted through an arranged spring damper. Therefore, the buffering effect of the supporting plate on the impact of the goods is further improved, and the service life of the spring and the supporting plate is prolonged.

[0002] A crane refers to a multi-action lifting machinery that can vertically lift and horizontally move heavy objects within a certain range. It is mainly used for lifting equipment, emergency, hoisting, machinery and rescue, etc.

[0003] After searching, for example, the utility model patent with Chinese patent publication number CN218560869U provides a loading and unloading crane with an infrared anti-collision structure. The utility model patent buffers the impact of the goods on the guard plate by setting a plurality of buffer springs. However, in the current market, the cargo carried by the crane is large in volume and weight. The buffering effect of the impact on the guard plate by relying solely on the buffer springs is poor and the life of the buffer springs will be greatly reduced. Therefore, a crane with an anti-collision structure is proposed to solve the above problems. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The crane hoisting anti-collision structure is provided with an anti-collision structure. When the buffer block is impacted by the hoisted cargo, the buffer block is pressed downward to rotate the two cams. The two cams drive the rotating rod to rotate. The rotating rod will reverse due to the torsion force of the torsion spring, so that the buffer block offsets a part of the impact to perform the first shock absorption. After that, the rotating rod compresses the spring through the gear, rack and slider. Due to the reset effect of the spring itself, a part of the buffering force can be offset to achieve the second shock absorption. The two sliders move away from each other and drive the moving plate to be pressed downward through the moving rod. Then the third shock absorption is performed through the set spring damper. Through the above-mentioned arrangement, multiple shock absorption is performed, thereby further improving the buffering effect of the support plate on the impact of the cargo, improving the service life of the spring and the support plate, and having greater practicality.

[0023] The anti-collision component 4 includes a slide bar 401, which is fixedly installed between the inner walls of the left and right sides of the support plate 3. Two sliders 402 are slidably mounted on the surface of the slide bar 401. Springs 403 are fixedly installed on the separated sides of the two sliders 402. Racks 404 are fixedly installed on the tops of the two sliders 402. Gears 405 are meshed on the tops of the two racks 404. Two rotating shafts 406 are rotatably installed on the inner rear wall of the support plate 3. Cams 407 are mounted on the surfaces of the two rotating shafts 406. A buffer block 408 is slidably installed inside the support plate 3. Two moving rods 409 are rotatably installed on the surfaces of the two sliders 402. A moving plate 410 is rotatably installed on the other ends of the two moving rods 409. Two dampers 411 are fixedly installed on the bottom of the moving plate 410, and torsion springs 412 are mounted on the surfaces of the two rotating shafts 406.

[0024] A number of universal wheels 2 are fixedly installed at the bottom of the base plate 1. The universal wheels 2 are arranged to facilitate the movement of the entire device. Brake pads are arranged on the universal wheels 2. The two ends of the torsion spring 412 are respectively installed between the front and rear inner walls of the support plate 3. The two springs 403 are respectively fixedly connected to the left and right inner walls of the support plate 3. Gears 405 are mounted on the surfaces of the two rotating shafts 406.

[0025] Two dampers 411 are fixedly mounted on the inner bottom wall of the support plate 3 , and a vertical plate 5 is fixedly mounted on the top of the bottom plate 1 near the left side.

[0026] A lifting assembly 6 is provided on the right side of the vertical plate 5, and the lifting assembly 6 includes two fixed plates 601, and the two fixed plates 601 are fixedly installed on the right side of the vertical plate 5. A placing plate 602 is fixedly installed on the top of the two fixed plates 601, and a motor 603 is fixedly installed on the surface of one of the placing plates 602, and a rotating rod 604 is fixedly installed on the output end of the motor 603, and a winding roller 605 is installed on the surface of the rotating rod 604. A lifting rope 606 is wound on the surface of the winding roller 605, and a cross plate 607 is fixedly provided at the bottom of the lifting rope 606, and a hook 608 is fixedly installed at the bottom of the cross plate 607. When in use, by starting the motor 603, the motor 603 drives the lifting rope 606 to be pulled up through the rotating rod 604 and the winding roller 605, and the lifting rope 606 drives the cross plate 607 and the hook 608 to move up, so as to facilitate the lifting of goods.

[0027] When implementing, follow these steps:

[0028] 1) When the buffer block 408 is impacted by the cargo, the buffer block 408 and the cam 407 drive the rotating shaft 406 to rotate. Due to the torsion of the torsion spring 412, the rotating shaft 406 is reversed to offset a part of the impact on the buffer block 408, thereby performing the first shock absorption;

[0029] 2) Then the rotating shaft 406 compresses the spring 403 through the gear 405, the rack 404 and the slider 402. The restoring effect of the spring 403 itself offsets part of the buffering force to achieve the second shock absorption;

[0030] 3) Finally, the two sliders 402 move away from each other, and the moving plate 410 is pressed downward through the moving rod 409, and then the third shock absorption is performed through the damper 411.

[0031] In summary, the anti-collision structure for hoisting of the crane is provided with an anti-collision component 4. When the buffer block 408 is impacted by the hoisted cargo, the buffer block 408 is pressed down to rotate the two cams 407. The two cams 407 drive the rotating shaft 406 to rotate. The rotating shaft 406 will reverse due to the torsion of the torsion spring 412, so that the buffer block 408 offsets part of the impact and performs the first shock absorption. Then the rotating shaft 406 compresses the spring 403 through the gear 405, the rack 404 and the slider 402. Due to the reset effect of the spring 403 itself, part of the buffering force can be offset to achieve the second shock absorption. The two sliders 402 move away from each other and drive the moving plate 410 to be pressed down through the moving rod 409, and then the third shock absorption is performed through the provided damper 411. Through the above-mentioned configuration, through multiple shock absorption, the buffering effect of the support plate 3 on the impact of cargo is further improved, the service life of the spring 403 and the support plate 3 is improved, and it has greater practicality.
