Anti-collision mechanism for a stacker

Abstract

This utility model relates to the field of stacker crane protection technology, and discloses an anti-collision mechanism for stacker cranes, including two sets of first anti-collision plates, and two sets of symmetrical second anti-collision plates inserted between the two sets of first anti-collision plates. Two sets of symmetrical fixing elements are arranged in the space between the first and second anti-collision plates. The stacker crane requiring anti-collision protection is placed in the space between the first and second anti-collision plates. Then, the hydraulic rod is activated, and its extension end extends forward. When the protrusion contacts the stacker crane, the limiting plate drives the rotating shaft to rotate. The protrusion rotates towards the inner wall of the moving frame around the center of the rotating shaft. The limiting plate drives the adjusting rod to slide inward along the middle end of the sleeve and retracts. The adjusting rod compresses the first spring. Under the reverse elastic force of the first spring, the impact force generated by the contact between the protrusion and the stacker crane can be buffered, avoiding direct hard contact between the protrusion and the stacker crane, thus preventing damage to the stacker crane.

Description

Technical Field

[0001] This utility model relates to the field of stacker crane protection technology, and in particular to an anti-collision mechanism for stacker cranes. Background Technology

[0002] Stacker cranes are core equipment in automated storage and retrieval systems (AS / RS), designed for high-density storage and rapid retrieval of goods. They move between racks via tracks or guide rails, using extendable forks to precisely store and retrieve goods. Their structure typically includes a metal frame, lifting mechanism, horizontal drive unit, and fork system. Equipped with laser navigation, barcode recognition, or visual positioning technology, they achieve centimeter-level operational accuracy. Compared to ordinary forklifts, stacker cranes offer high-speed operation, unmanned operation, and the ability to adapt to multiple rack levels. They can operate continuously 24 hours a day, significantly improving warehouse space utilization and logistics efficiency.

[0003] During the handling and transportation of stacker cranes, they are prone to collisions with external objects, which can damage the machinery. Furthermore, the existing anti-collision mechanisms of stacker cranes cannot be adjusted according to different models of stacker cranes, resulting in poor practicality. Utility Model Content

[0004] In view of the fact that stacker cranes are prone to collisions with external objects during handling and transportation, which can cause damage to the machinery, and that the existing anti-collision mechanisms of stacker cranes cannot be adjusted according to different models of stacker cranes, resulting in poor practicality, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a collision avoidance mechanism for a stacker crane, comprising two sets of first collision avoidance plates, two sets of symmetrical second collision avoidance plates inserted between the two sets of first collision avoidance plates, two sets of symmetrical fixing elements disposed in the space between the first and second collision avoidance plates, each fixing element comprising a movable frame disposed between the first and second collision avoidance plates, a limiting plate inserted at the middle of the movable frame, a rotating shaft fixedly inserted at the middle of the limiting plate, multiple sets of adjusting components disposed on the lower outer wall of the limiting plate, each adjusting component comprising a sleeve disposed at the bottom of the movable frame, an adjusting rod inserted at the middle of the sleeve, a first spring disposed at the lower end of the adjusting rod, two sets of symmetrical gears disposed at the upper and lower ends of one side of the outer wall of the movable frame, a sliding rod fixedly disposed at the lower end of the outer wall of the movable frame, a slider sleeved on the outer wall of the sliding rod, a reinforcing component disposed at the upper end of the slider, the reinforcing component comprising a toothed rod disposed at the upper end of the slider, a telescopic rod inserted at the middle end of the toothed rod, and a second spring disposed at one end of the telescopic rod.

[0006] As a preferred embodiment of the anti-collision mechanism for stacker cranes described in this utility model, the limiting plate is movably inserted into the end of the moving frame, the end of the rotating shaft away from the gear is rotatably connected to the inner wall of the moving frame, and one end of the rotating shaft movably passes through the inner wall of the moving frame and is fixedly connected to the middle end of one set of gears.

[0007] As a preferred embodiment of the anti-collision mechanism for stacker cranes described in this utility model, a protrusion is fixedly provided on the lower outer wall of the limiting plate.

[0008] As a preferred embodiment of the anti-collision mechanism for stacker cranes described in this utility model, the two sets of gears mesh with each other, one set of gears meshes with a rack, the telescopic rod is movably inserted into the middle end of the rack, the second spring is movably inserted into the inner cavity of the rack, and the slider is movably sleeved on the outer wall of the slider rod.

[0009] As a preferred embodiment of the anti-collision mechanism for stacker cranes described in this utility model, the adjusting rod is movably inserted into the middle end of the sleeve, the first spring is movably inserted into the inner cavity of the sleeve, the lower end of the sleeve is hinged to the moving frame, and the upper end of the adjusting rod is hinged to the outer wall of the limiting plate.

[0010] As a preferred embodiment of the anti-collision mechanism for stacker cranes described in this utility model, a hydraulic rod is fixedly provided at the middle of the outer wall of the first anti-collision plate, and the extension end of the hydraulic rod is fixedly connected to the movable frame.

[0011] As a preferred embodiment of the anti-collision mechanism for stacker cranes described in this utility model, the first anti-collision plate is provided with two sets of mutually symmetrical fixing blocks at its upper end, and bolts are threaded into the upper end of the fixing blocks. The second anti-collision plate is provided with threaded holes that cooperate with the bolts at its upper end.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. In this utility model, during the process of fixing the stacker, two sets of gears rotate simultaneously in opposite directions. The slider at the lower end of the rack slides along the slide bar, and the telescopic rod moves closer to the stacker. When the telescopic rod contacts the stacker, the stacker pushes the telescopic rod to retract inward along the middle end of the rack, and the telescopic rod compresses the second spring. When the limiting plate rotates to be parallel with the moving frame, the hydraulic rod is closed. Under the reverse elastic force of the second spring, the telescopic rod is pushed forward, and the telescopic rod moves closer to the stacker to further clamp the stacker, avoiding the problem of unstable placement of the stacker due to insufficient clamping.

[0014] 2. In this utility model, the stacker crane requiring anti-collision protection is placed in the space between the first and second anti-collision plates. Then, the hydraulic rod is activated, and the extension end of the hydraulic rod extends forward. When the protrusion comes into contact with the stacker crane, the limiting plate drives the rotating shaft to rotate. The protrusion rotates towards the inner wall of the moving frame with the center of the rotating shaft as the axis. The limiting plate drives the adjusting rod to slide and retract inward along the middle end of the sleeve, and the adjusting rod compresses the first spring. Under the reverse elastic force of the first spring, the impact force generated by the contact between the protrusion and the stacker crane can be buffered, avoiding direct hard contact between the protrusion and the stacker crane, which would damage the stacker crane.

[0024] Reference Figures 1-5This is the first embodiment of the present invention, providing an anti-collision mechanism for a stacker crane, including two sets of first anti-collision plates 1, two sets of symmetrical second anti-collision plates 2 inserted between the two sets of first anti-collision plates 1, and two sets of symmetrical fixing elements 3 arranged in the space between the first anti-collision plates 1 and the second anti-collision plates 2. The fixing element 3 includes a movable frame 31 disposed between the first anti-collision plates 1 and the second anti-collision plates 2, a limiting plate 32 inserted at the middle of the movable frame 31, a rotating shaft 33 fixedly inserted at the middle of the limiting plate 32, and multiple sets of adjusting components 35 provided on the lower outer wall of the limiting plate 32 for adjustment. Component 35 includes a sleeve 351 located at the bottom of the movable frame 31. An adjusting rod 352 is inserted into the middle of the sleeve 351. A first spring 353 is located at the lower end of the adjusting rod 352. Two sets of symmetrical gears 36 are located at the upper and lower ends of one side of the outer wall of the movable frame 31. A sliding rod 39 is fixedly located at the lower end of the outer wall of the movable frame 31. A slider 38 is sleeved on the outer wall of the sliding rod 39. A reinforcing component 37 is located at the upper end of the slider 38. The reinforcing component 37 includes a toothed rod 371 located at the upper end of the slider 38. A telescopic rod 372 is inserted into the middle of the toothed rod 371. A second spring 373 is located at one end of the telescopic rod 372.

[0025] The limiting plate 32 is movably inserted in the middle of the moving frame 31. The end of the rotating shaft 33 away from the gear 36 is rotatably connected to the inner wall of the moving frame 31. One end of the rotating shaft 33 moves through the inner wall of the moving frame 31 and is fixedly connected to the middle of one of the gears 36.

[0026] A protrusion 34 is fixedly provided on the lower outer wall of the limiting plate 32.

[0027] Two sets of gears 36 mesh with each other, one set of gears 36 meshes with the rack 371, the telescopic rod 372 is movably inserted into the middle end of the rack 371, the second spring 373 is movably inserted into the inner cavity of the rack 371, and the slider 38 is movably sleeved on the outer wall of the slider 39.

[0028] The adjusting rod 352 is movably inserted into the middle of the sleeve 351, the first spring 353 is movably inserted into the inner cavity of the sleeve 351, the lower end of the sleeve 351 is hinged to the moving frame 31, and the upper end of the adjusting rod 352 is hinged to the outer wall of the limiting plate 32.

[0029] A hydraulic rod 4 is fixedly installed at the middle of the outer wall of the first anti-collision plate 1, and the extended end of the hydraulic rod 4 is fixedly connected to the movable frame 31.

[0030] The upper end of the first anti-collision plate 1 is provided with two sets of symmetrical fixing blocks 5, and the upper end of the fixing block 5 is threaded with bolts 6. The upper end of the second anti-collision plate 2 is provided with threaded holes that cooperate with the bolts 6.

[0031] The stacker crane requiring anti-collision protection is placed in the space between the first anti-collision plate 1 and the second anti-collision plate 2. Then, the hydraulic rod 4 is activated, and the extension end of the hydraulic rod 4 extends forward. When the protrusion 34 contacts the stacker crane, the limiting plate 32 drives the rotating shaft 33 to rotate. The protrusion 34 rotates towards the inner wall of the moving frame 31 with the center of the rotating shaft 33 as the axis. The limiting plate 32 drives the adjusting rod 352 to slide and retract inward along the middle end of the sleeve 351, and the adjusting rod 352 compresses the first spring 353. Under the reverse elastic force of the first spring 353, the impact force generated by the contact between the protrusion 34 and the stacker crane can be buffered, avoiding direct hard contact between the protrusion 34 and the stacker crane, which could damage the stacker crane. This allows for buffering of the stacker crane during the fixing process. The rotating shaft 33 drives one of the sets of gears 36 connected to it to rotate. The two sets of gears 36 mesh with each other, so that the two sets of gears 36 rotate simultaneously. Furthermore, the rotation directions are opposite, and the rack 371 and gear 36 mesh with each other, so that the slider 38 set at the lower end of the rack 371 slides along the slide bar 39, and the telescopic rod 372 moves closer to the stacker. When the telescopic rod 372 contacts the stacker, the stacker pushes the telescopic rod 372 to retract inward along the middle end of the rack 371, and the telescopic rod 372 compresses the second spring 373. When the limiting plate 32 rotates to be parallel with the moving frame 31, the hydraulic rod 4 is closed. Under the reverse elastic force of the second spring 373, the telescopic rod 372 is pushed forward, and the telescopic rod 372 moves closer to the stacker to further clamp the stacker, avoiding the problem of unstable placement of the stacker due to insufficient clamping. The first anti-collision plate 1 and the second anti-collision plate 2 can protect the stacker and prevent external objects from impacting the stacker during transportation, thus protecting the safety of the stacker during transportation.

[0032] Before using the device, the two sets of second anti-collision plates 2 can be combined together, and the first anti-collision plate 1 can be placed at both ends of the second anti-collision plate 2. Then, the bolts 6 are screwed in along the upper end of the fixing block 5 so that the lower end of the bolts 6 is inserted into the threaded hole opened at the upper end of the second anti-collision plate 2. This completes the fixing of the first anti-collision plate 1 and the second anti-collision plate 2, thus facilitating the assembly of the device.
