Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacker crane technology, and in particular to a stacker crane. Background Technology
[0002] A stacker crane is a type of warehousing equipment that primarily uses forks or levers as picking devices. It is a specialized device used in warehouses, workshops, and other locations to grab, transport, and stack goods, or to retrieve and place unit goods from high-rise shelves.
[0003] Most existing stacker cranes use synchronous toothed belts to move the platform up and down to achieve the stacker crane's picking function. However, after a long period of use, the teeth of the synchronous toothed belt will accumulate metal debris from wear between the synchronous toothed belt and the gears. When the metal debris inside the synchronous toothed belt encounters the gears, it will cause the synchronous toothed belt to vibrate, accelerate the wear of the synchronous toothed belt, and reduce its service life. Utility Model Content
[0004] The purpose of this invention is to provide a stacker machine to solve the problem mentioned in the background art that when metal debris inside the synchronous toothed belt encounters gears, it causes the synchronous toothed belt to vibrate and accelerates the wear of the synchronous toothed belt.

A reciprocating screw is rotatably connected between the two fixed plates four. The gear four is fixedly connected to the opposite end of the reciprocating screw. A sleeve plate is threaded onto the outer wall of the reciprocating screw. One side of the sleeve plate abuts against the inner cavity of the H-shaped track.

Two rubber-coated wheels are rotatably connected between each set of connecting plates II and on both sides of connecting plate I. The two rubber-coated wheels are rotatably connected to the outer wall of the H-shaped track. The rubber-coated wheels on both sides of connecting plate I and the two rubber-coated wheels on the inner wall of connecting plate II are respectively located in the inner cavities on both sides of the H-shaped track.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides, for example Figure 1-4 The stacker crane shown includes an H-shaped track 1, a gear 2 16 rotatably connected to the top of the H-shaped track 1, a gear 8 rotatably connected to the bottom of the H-shaped track 1, a synchronous toothed belt 2 meshing with the gear 8 and the rotating shaft 9, a fork fixing plate 11 provided on the outer wall of the synchronous toothed belt 2, a detachable drive device provided at the bottom of the gear 8, and a cleaning device for cleaning the teeth of the H-shaped track 1 provided on the inner wall of the H-shaped track 1.
[0020] To address the problem of metal debris on the teeth of the existing stacker crane's synchronous toothed belt 2 causing vibration, this invention incorporates a cleaning device inside the H-shaped track 1, enabling autonomous cleaning during the operation of the synchronous toothed belt 2.
[0021] like Figure 4 As shown, the cleaning device includes a fixed plate 17 fixedly connected to the H-shaped track 1. One end of the fixed plate 17 is rotatably connected to a gear 18 that is reasonably connected to the teeth of the synchronous toothed belt 2. A gear 19 is meshed above the gear 18. Two fixed plates 20 are fixedly connected in the inner cavity of the H-shaped track 1. The gear 18 is rotatably connected to one of the fixed plates 20. A reciprocating screw 21 is rotatably connected between the two fixed plates 20. The gear 19 is fixedly connected to the opposite end of the reciprocating screw 21. A sleeve 22 is threaded onto the outer wall of the reciprocating screw 21. One side of the sleeve 22 abuts against the inner cavity of the H-shaped track 1. A cleaning brush 23 is inserted into the inside of the sleeve 22. The cleaning brush 23 is fixedly connected to the sleeve 22 by fastening bolts.
[0022] When the cleaning device is in use, the stacker is first started, causing the synchronous toothed belt 2 to rotate. When the synchronous toothed belt 2 rotates, the teeth of the synchronous toothed belt 2 drive the gear three 18 to rotate. The rotation of the gear three 18 drives the gear four 19 to rotate, and the gear four 19 drives the reciprocating screw 21 to rotate. Since one end of the sleeve 22 abuts against the inner cavity of the H-shaped track 1, the sleeve 22 is prevented from rotating synchronously with the reciprocating screw 21. Thus, the sleeve 22 moves back and forth along the reciprocating screw 21, thereby enabling the cleaning brush 23 on one side of the sleeve 22 to clean the teeth of the synchronous toothed belt 2, thus enabling the stacker to self-clean during operation.
[0023] like Figure 2 As shown, a connecting plate 13 is fixedly connected to one side of the fork fixing plate 11, and one end of the connecting plate 13 is fixedly connected to the outer wall of the synchronous toothed belt 2.
[0024] like Figure 2 and Figure 3 As shown, two sets of connecting plates 15 are fixedly connected to one side of the fork fixing plate 11. Each set of connecting plates 15 consists of two plates. Two rubber-coated wheels 12 are rotatably connected between each set of connecting plates 15 and on both sides of the connecting plate 13. The two rubber-coated wheels 12 are rotatably connected to the outer wall of the H-shaped track 1. The rubber-coated wheels 12 on both sides of the connecting plate 13 and the two rubber-coated wheels 12 on the inner wall of the connecting plate 15 are respectively located in the inner cavities on both sides of the H-shaped track 1. The rubber-coated wheels 12 on both sides of the connecting plate 13 and the two rubber-coated wheels 12 on the inner wall of the connecting plate 15 are respectively located on both sides of the synchronous toothed belt 2.
[0025] When the fork fixing plate 11 moves up and down, the rubber-coated wheels 12 move upward along the inner wall of the H-shaped track 1. Compared with the existing friction movement, this can reduce the noise of the stacker crane. At the same time, the rubber-coated wheels 12 on both sides of the connecting plate 13 and the two rubber-coated wheels 12 on the inner wall of the connecting plate 2 15 are located in the inner cavities on both sides of the H-shaped track 1, which can stably move the fork fixing plate 11 along the H-shaped track 1.
[0026] like Figure 1 As shown, the drive device includes a servo motor 3, a reducer 4 is fixedly connected to the output end of the servo motor 3, a fixed plate 5 is fixedly connected to the top of the reducer 4, a fixed plate 6 is rotatably connected to the top of the fixed plate 5, and the fixed plate 6 is connected to the H-shaped rail 1 by fastening bolts. The servo motor 3 drives the reducer 4 to rotate, the reducer 4 drives the rotating shaft 9 to rotate, the rotating shaft 9 drives the gear 8 to rotate, thereby realizing the rotation of the synchronous toothed belt 2, which in turn drives the fork fixing plate 11 to move up and down.
[0027] like Figure 1As shown, the output end of the reducer 4 is fixedly connected to a rotating shaft 9, and one end of the rotating shaft 9 passes through a gear 8 and is fixedly connected to a bearing 10. The bearing 10 is fixedly connected to the H-shaped track 1.
[0028] like Figure 2 As shown, two limit switches 14 are fixedly connected to the outer wall of the H-shaped track 1. The limit switches 14 limit the fork fixing plate 11 to prevent the fork fixing plate 11 from being too high or too low and causing accidental collision with the parts of the stacker crane.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
