Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, specifically a stacker crane guiding device. Background Technology

[0002] The stacker crane guiding device is one of the key components for the operation of stacker cranes in automated storage and retrieval systems (AS / RS). Its main function is to ensure that the stacker crane can operate accurately and stably within the racking aisles. The design and manufacturing quality of the guiding device directly affects the operating efficiency and safety of the stacker crane.

[0003] By setting tracks on both sides of the rack aisle, the stacker crane is guided by the contact between the wheels and the tracks. Track guidance has the advantages of simple structure, low manufacturing cost and convenient maintenance.

[0004] Because stacker cranes need to move to a designated position on a track using electric wheels during cargo handling, the weight of the end of the stacker crane carrying cargo on the track is much greater than that of the other end without cargo. As the crane moves along the track, the center of gravity will tilt towards the side carrying cargo, which can easily cause the electric wheels to derail. Utility Model Content

[0005] The purpose of this utility model is to provide a stacker crane guiding device to solve the problem mentioned in the background art, where the center of gravity tilts to the side carrying the goods during the movement on the track, which can easily cause the electric vehicle wheels to derail when moving on the track.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stacker crane guiding device, comprising: a guide rail, an electric vehicle wheeled slider, a moving component, a counterweight, and a connecting component. The main body of the guiding device consists of a guide rail and an electric vehicle wheeled slider slidably mounted on the guide rail. The electric vehicle wheeled slider has small motor-driven wheels around its circumference. The moving component is located at the bottom of the electric vehicle wheeled slider and includes a placement frame fixed to the bottom of the electric vehicle wheeled slider. The counterweight is located inside the placement frame, and the counterweight consists of several sets. The connecting component is located outside the moving component.

[0007] By adopting the above technical solution, the weight on both sides can be kept consistent when moving on the guide rail, thereby achieving stability during movement.

[0008] Preferably, the movable component further includes two sets of fixing plates fixed on both sides of the outer wall of the placement frame. The fixing plates have holes and bearings are welded inside the holes.

[0009] By adopting the above technical solution, the bearing can provide fixation for the threaded rod without affecting its rotation.

[0010] Preferably, the moving component further includes a No. 1 motor fixed on the outer wall of one of the sets of fixed plates, a threaded rod with both ends disposed in the bearings of the two sets of fixed plates, and a guide rod welded to the inner wall of the two sets of fixed plates, wherein one end of the threaded rod is connected to the output end of the No. 1 motor.

[0011] By adopting the above technical solution, the No. 1 motor can provide a threaded rod to achieve stable rotation.

[0012] Preferably, the moving component further includes a conveying roller rotatably disposed at the inner bottom of the placement frame, the number of the conveying rollers being several sets, and the counterweight being disposed above the conveying rollers.

[0013] By adopting the above technical solution, the counterweight can achieve stable horizontal movement through the conveyor rollers.

[0014] Preferably, the plug-in assembly includes a movable block with one end threadedly connected to a threaded rod, the other end of the movable block being slidably disposed on a guide rod, a groove being provided inside the movable block, a plug-in block being slidably disposed in the groove of the movable block, and a connecting rod being welded inside the plug-in block.

[0015] By adopting the above technical solution, the plug-in block can achieve stable displacement within the sliding groove of the moving block.

[0016] Preferably, the plug-in assembly further includes a second motor fixed on the outer wall of the movable block and a toggle block fixed on the output end of the second motor via a shaft. The toggle block has a rectangular hole, and the connecting rod is disposed inside the rectangular hole of the toggle block.

[0017] By adopting the above technical solution, the rotation of the actuating block can drive the connecting rod to produce horizontal displacement.

[0018] In summary, this utility model has the following beneficial effects: by providing a moving component, a counterweight, and a connecting component, the weight of the counterweight can counteract the tilting state caused by transporting goods on one side. Furthermore, through the cooperation of the moving component and the connecting component, multiple sets of counterweights can be automatically moved to designated positions, thereby ensuring that the weight borne by both sides is relatively consistent when transporting goods of different weights, and improving the stability of the electric vehicle wheeled slider during its movement on the guide rail.

[0025] 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.

[0026] The following is in conjunction with the appendix Figure 1-5 The embodiments of this utility model will be described in further detail.

[0027] Example 1

[0028] Please see Figures 1-5 This embodiment provides a technical solution: a stacker crane guiding device, including: a guide rail 1, an electric vehicle wheeled slider 2, a moving component 3, a counterweight 4, and a plug-in component 5;

[0029] The main body of the guiding device consists of a guide rail 1 and an electric vehicle wheel slider 2 that is slidably mounted on the guide rail 1. The electric vehicle wheel slider 2 has small motor-driven wheels around its slider. The above is the prior art and will not be described in detail below.

[0030] The moving component 3 is located at the bottom of the slider of the electric vehicle wheel slider 2. The moving component 3 includes a placement frame 301 fixed to the bottom of the slider of the electric vehicle wheel slider 2, and two sets of fixing plates 302 fixed to both sides of the outer wall of the placement frame 301. The fixing plates 302 have holes and bearings are welded inside the holes. A first motor 303 is fixed to the outer wall of one set of fixing plates 302. Threaded rods 304 with both ends set in the bearings of the two sets of fixing plates 302 and guide rods 305 welded to the inner walls of the two sets of fixing plates 302 are also included. One end of the threaded rod 304 is connected to the output end of the first motor 303. A conveying roller 306 is rotatably set at the inner bottom of the placement frame 301. There are several sets of conveying rollers 306, and a counterweight 4 is set above the conveying rollers 306.

[0031] The counterweight 4 is located inside the placement frame 301, and the number of counterweights 4 consists of several groups. The plug-in component 5 is located outside the moving component 3.

[0032] The electric vehicle wheeled slider 2 can be fixed to the stacker crane by bolts. When the stacker crane is moving goods, the other side of the electric vehicle wheeled slider 2 without goods will tilt. At this time, the plug-in component 5 is needed to limit one side of the counterweight 4. The position of the plug-in component 5 can be adjusted by moving component 3, thereby driving the counterweight 4 to move and maintaining the stability of the electric vehicle wheeled slider 2 when moving on the guide rail 1.

[0033] When it is necessary to move the plug-in block 502 and the counterweight block 4 on one side to achieve displacement, the first motor 303 on the fixed plate 302 outside the frame 301 is started. The first motor 303 will drive the threaded rod 304 on the output end to rotate. During the rotation of the threaded rod 304, it can drive the moving block 501 to achieve stable displacement on the guide rod 305. During the synchronous movement of the plug-in block 502, it can push the counterweight block 4 to achieve stable movement on the conveyor roller 306.

[0034] Example 2

[0035] Please see Figures 1-5 This embodiment provides a technical solution: a stacker crane guiding device, including: a moving block 501, a plug-in block 502, a connecting rod 503, a second motor 504, and a toggle block 505;

[0036] The plug-in assembly 5 includes a movable block 501 with one end threadedly connected to the threaded rod 304, and the other end of the movable block 501 slidably disposed on the guide rod 305. A groove is provided inside the movable block 501, a plug-in block 502 is slidably disposed in the groove of the movable block 501, and a connecting rod 503 is welded inside the plug-in block 502. A second motor 504 is fixed on the outer wall of the movable block 501, and a toggle block 505 is fixed on the output end of the second motor 504 through a shaft. The toggle block 505 has a rectangular hole, and the connecting rod 503 is disposed inside the rectangular hole of the toggle block 505.

[0037] By starting the second motor 504, the actuating block 505 is driven to rotate. During the rotation of the actuating block 505, the connecting rod 503 inside the hole and the plug-in block 502 outside the connecting rod 503 are displaced inside the sliding groove of the moving block 501. At this time, the plug-in block 502 will be inserted into the gap between the two sets of counterweights 4. The moving component 3 can drive the plug-in block 502 and the counterweight 4 on one side to move.

[0038] The implementation principle of the stacker crane guiding device of this utility model is as follows:

[0039] First, the electric vehicle wheel slider 2 can be fixed to the stacker crane by bolts. When the stacker crane is transporting goods, the other side of the electric vehicle wheel slider 2 without goods will tilt. At this time, the plug-in component 5 is needed to limit one side of the counterweight 4. The position of the plug-in component 5 can be adjusted by moving the component 3, thereby driving the counterweight 4 to move and maintaining the stability of the electric vehicle wheel slider 2 when it moves on the guide rail 1.

[0040] Secondly, by starting the second motor 504, the actuating block 505 is driven to rotate. During the rotation of the actuating block 505, the connecting rod 503 inside the hole and the plug-in block 502 outside the connecting rod 503 are displaced inside the sliding groove of the moving block 501. At this time, the plug-in block 502 will be inserted into the gap between the two sets of counterweights 4. The moving component 3 can drive the plug-in block 502 and the counterweight 4 on one side to move.

[0041] Finally, when it is necessary to move the plug-in block 502 and the counterweight block 4 on one side to achieve displacement, start the first motor 303 on the fixed plate 302 outside the frame 301. The first motor 303 will drive the threaded rod 304 on the output end to rotate. During the rotation of the threaded rod 304, it can drive the moving block 501 to achieve stable displacement on the guide rod 305. During the synchronous movement of the plug-in block 502, it can push the counterweight block 4 to achieve stable movement on the conveying roller 306.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
