Description

Technical Field

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

[0002] A stacker crane overhead rail guide is a guiding system used to guide and control the operation of a stacker crane. It typically consists of an overhead rail and guide devices on the stacker crane.

[0003] A stacker crane overhead rail is a guide rail fixed to the warehouse ceiling to guide the stacker crane to move within the warehouse. Overhead rails are usually made of high-strength, durable materials, such as steel or aluminum alloy, to ensure their stability and load-bearing capacity.

[0004] The guide device is a device installed on the top of the stacker crane and connected to the overhead rail. The existing guide wheels are mostly fixed in the installation position on the guide device. When the guide device is installed on the overhead rail, there will be gaps between it and the guide rail. This will result in poor stability of the guide device when assisting the stacker crane to move, and it will be difficult to flexibly adjust the precision of the fit between the guide wheel and the rail.

[0005] In addition, the existing stacker crane overhead rail guide device does not have an automatic lubrication function. During routine maintenance, the user has to climb to a high place to lubricate the rail and pulleys, which is not very convenient to use.

[0006] In addition, when the guide device stops, it is prone to inductive collision with the two ends of the overhead rail, resulting in poor protection when the stacker crane stops running. Utility Model Content

The synchronous opposing movement of the mounting seat in the mounting box can be achieved through the cooperation of the bidirectional screw rod and the adjustment knob.

[0013] The present invention is further configured such that the locking structure includes multiple sets of locking plates arranged in an array on the outside of the bidirectional screw, and locking nuts are screwed onto the outer threads of the multiple sets of locking plates. The locking nuts and locking plates can be used to lock and fix the bidirectional screw on the mounting box.

[0014] The present invention is further provided with an anti-slip pad on the inner side of each locking piece, which can improve the surface anti-slip properties of the locking piece.

[0015] The present invention is further configured such that a limiting slider is provided at the bottom end of the mounting base, and a limiting groove is provided in the inner cavity of the mounting box to cooperate with the limiting slider. The cooperation between the limiting slider and the limiting groove can improve the movement stability of the mounting base in the mounting box.

[0016] The present invention is further configured such that the buffer protection structure includes a buffer protection pad disposed on the surface of the protective plate, and the surface of the buffer protection pad is uniformly provided with multiple buffer protrusions. The buffer protection pad and the buffer protrusions can improve the impact protection effect of the surface of the protective plate.

[0017] The present invention is further provided with a plurality of anti-slip protrusions evenly provided on the extended end of the bidirectional screw. The anti-slip protrusions can improve the locking and anti-slip effect of the locking plate on the bidirectional screw.

[0018] The present invention is further configured such that a liquid injection tube is provided on the storage box, and a sealing cap is provided on the liquid injection tube to realize the replenishment of lubricating oil in the storage box.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the present invention provides a stacker crane overhead rail guide device, which has the following beneficial effects:

[0021] 1. This utility model includes a track and a frame. Two sets of mounting boxes are symmetrically arranged at both ends of the frame. Two sets of mounting seats are symmetrically arranged inside each mounting box. A synchronous opposing movement structure is provided in conjunction with the mounting seats. A mounting column is provided on each mounting seat, and a guide wheel is rotatably mounted on the mounting column via a bearing. The guide wheel rolls in conjunction with the track. The synchronous opposing movement structure includes a bidirectional screw rod rotatably mounted inside the mounting box via a bearing. The mounting seat is threaded onto the bidirectional screw rod, which extends to the outside of the mounting box and is equipped with an adjustment knob. A locking structure is provided on the mounting box in conjunction with the bidirectional screw rod. The locking structure includes… The system includes multiple sets of locking plates arranged on the outside of the bidirectional screw. Locking nuts are screwed onto the outer threads of these locking plates. When guiding the stacker crane's overhead rail, the guide wheels are positioned on either side of the rail. Turning the adjustment knob controls the rotation of the bidirectional screw. The threaded engagement between the bidirectional screw and the mounting base allows the two mounting bases to move synchronously towards each other within the mounting box. The movement of the mounting bases controls the relative movement of the mounting column and the guide wheels, thereby adjusting the distance between the two sets of guide wheels. This improves the accuracy and stability of the connection between the guide wheels and the rail.

[0022] After adjusting to the appropriate position, tighten the locking nut onto the locking plate to lock and fix the double-ended screw, thereby achieving stable installation of the mounting base in the mounting box and improving the stability of the guide wheel when it moves on the track.

[0023] 2. This utility model has a spring assembly on the outside of the mounting box, a protective plate on the outside of the spring assembly, and a buffer protection structure on the surface of the protective plate. The buffer protection structure includes a buffer pad on the surface of the protective plate, and multiple buffer protrusions are evenly distributed on the surface of the buffer pad. In this way, when the frame is moving with the stacker crane and the stacker crane needs to be stopped, the protective plate can come into contact with the external impact interface, causing the spring assembly to contract, thereby assisting the frame to stop and avoiding rigid impact between the frame and the external interface. The buffer pad and buffer protrusions can further enhance the impact resistance of the frame.

[0024] 3. This utility model has a storage box on the frame, a pump body connected to the storage box, and a delivery pipe at the output end of the pump body. The tail end of the delivery pipe extends to both sides of the track and is equipped with atomizing nozzles. In this way, when the guide wheel moves on the track, the pump body can be activated to draw out the lubricating oil from the storage box and deliver it to the atomizing nozzles through the delivery pipe for spraying outward, thereby spraying lubricating oil on the track surface, reducing the moving friction resistance between the guide wheel and the track, and improving the smoothness of the stacker crane movement.

[0034] Please see Figure 1-5 A stacker crane overhead rail guide device includes a rail 1 and a frame 2. Two sets of mounting boxes 3 are symmetrically arranged at both ends of the frame 2. Two sets of mounting seats 4 are symmetrically arranged inside the mounting boxes 3. A synchronous opposing movement structure is provided in cooperation with the mounting seats 4. Mounting columns 5 are provided on the mounting seats 4. Guide wheels 6 are rotatably mounted on the mounting columns 5 through bearings. The guide wheels 6 are in rolling cooperation with the rail 1. The synchronous opposing movement structure includes a bidirectional screw 13 rotatably mounted in the mounting box 3 through bearings. The mounting seats 4 are threaded onto the bidirectional screw 13. The bidirectional screw 13 extends to the outside of the mounting box 3 and is provided with an adjustment knob 14. A locking structure is provided on the mounting box 3 in cooperation with the bidirectional screw 13. The locking structure includes multiple sets of locking plates 15 arranged in an array on the outside of the bidirectional screw 13. Locking nuts 16 are screwed onto the outer threads of the multiple sets of locking plates 15.

[0035] Specifically, when guiding the stacker crane's overhead rail, the guide wheels 6 are positioned on both sides of the track 1. The adjustment knob 14 is turned to control the rotation of the bidirectional screw 13. The threaded engagement between the bidirectional screw 13 and the mounting base 4 controls the synchronous movement of the two sets of mounting bases 4 in the mounting box 3. The movement of the mounting bases 4 controls the mutual movement between the mounting column 5 and the guide wheels 6, thereby adjusting the distance between the two sets of guide wheels 6. This improves the accuracy and stability of the connection between the guide wheels 6 and the track 1.

[0036] After adjusting to the appropriate position, tighten the locking nut 16 onto the locking plate 15 to lock and fix the double-ended screw 13, thereby achieving stable installation of the mounting base 4 in the mounting box 3 and improving the stability of the guide wheel 6 when it moves on the track 1.

[0037] This utility model features a spring assembly 7 on the outside of the mounting box 3, a protective plate 8 on the outside of the spring assembly 7, and a buffer protection structure on the surface of the protective plate 8. The buffer protection structure includes a buffer pad 20 on the surface of the protective plate 8, and multiple buffer protrusions 21 are evenly distributed on the surface of the buffer pad 20. In this way, when the frame 2 is moving with the stacker crane and the stacker crane needs to be stopped, the protective plate 8 can come into contact with the external impact interface, causing the spring assembly 7 to contract, thereby assisting the frame 2 to stop and avoiding rigid impact between the frame 2 and the external interface. The buffer pad 20 and the buffer protrusions 21 can further enhance the impact resistance of the frame 2.

[0038] This invention features a storage box 9 on a frame 2, a pump body 10 connected to the storage box 9, and a delivery pipe 11 at the output end of the pump body 10. The tail end of the delivery pipe 11 extends to both sides of the track 1 and is equipped with atomizing nozzles 12. Thus, when the guide wheel 6 moves on the track 1, the pump body 10 can be activated to extract the lubricating oil from the storage box 9 and deliver it to the atomizing nozzles 12 through the delivery pipe 11 for spraying outward. This achieves the spraying of lubricating oil on the surface of the track 1, thereby reducing the moving friction resistance between the guide wheel 6 and the track 1 and improving the smoothness of the stacker crane's movement.

[0039] Please see Figures 1-5 As one implementation of the locking plate 15: each locking plate 15 is provided with an anti-slip pad 17 on its inner side. The anti-slip pad 17 can increase the friction force when the locking plate 15 presses and fixes the bidirectional screw 13, thereby improving the locking effect of the locking plate 15 on the bidirectional screw 13.

[0040] Please see Figures 1-5 As one embodiment of the mounting base 4: a limiting slider 18 is provided at the bottom of the mounting base 4, and a limiting groove 19 is provided in the inner cavity of the mounting box 3 in cooperation with the limiting slider 18. The cooperation between the limiting slider 18 and the limiting groove 19 can improve the movement stability of the mounting base 4 in the mounting box 3.

[0041] Please see Figures 1-5 As one embodiment of the bidirectional screw 13: the extended end of the bidirectional screw 13 is uniformly provided with a plurality of anti-slip protrusions 22.

[0042] Specifically, the anti-slip ridge 22 can improve the locking stability of the locking plate 15 to the bidirectional screw 13 and improve the installation stability of the mounting base 4 in the mounting box 3.

[0043] Please see Figures 1-5 As one embodiment of the storage box 9: the storage box 9 is provided with a liquid injection tube 23, and a sealing cap 24 is provided on the liquid injection tube 23.

[0044] Specifically, the injection tube 23 facilitates the addition of lubricating oil into the storage box 9, and the sealing cap 24 enables the injection tube 23 to be sealed and closed.

[0045] In summary, when using the overall equipment:

[0046] Place the guide wheels 6 on both sides of the track 1, and turn the adjustment knob 14. The adjustment knob 14 can control the rotation of the bidirectional screw 13. The threaded engagement between the bidirectional screw 13 and the mounting base 4 can control the two sets of mounting bases 4 to move synchronously towards each other in the mounting box 3. The movement of the mounting base 4 controls the mutual movement between the mounting column 5 and the guide wheels 6, thereby adjusting the distance between the two sets of guide wheels 6, so that the guide wheels 6 fit closely with the guide rail, thereby improving the accuracy and stability of the connection between the guide wheels 6 and the track 1.

[0047] After adjusting to the appropriate position, tighten the locking nut 16 onto the locking plate 15 to lock and fix the locking plate 15 onto the bidirectional screw 13, thereby achieving stable installation of the mounting base 4 in the mounting box 3 and improving the stability of the guide wheel 6 when it moves on the track 1.

[0048] During use, the pump body 10 is started, and the lubricating oil in the storage box 9 is drawn out through the pump body 10 and delivered to the atomizing nozzle 12 through the delivery pipe 11 and sprayed outward, thereby spraying the lubricating oil on the surface of the track 1, thereby reducing the moving friction resistance between the guide wheel 6 and the track 1 and improving the smoothness of the stacker crane when it moves.

[0049] Meanwhile, when the stacker crane needs to be stopped during the movement of the frame 2 carrying the stacker crane, the protective plate 8 can come into contact with the external impact interface, causing the spring assembly 7 to contract, thereby assisting the frame 2 to stop and avoiding rigid impact between the frame 2 and the external interface. The setting of the buffer protective pad 20 and the buffer protrusion 21 can further enhance the impact resistance of the frame 2.

[0050] In all the solutions mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although the embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.

[0051] In all the solutions mentioned above, the operation of electrical components is controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and circuit connections are existing, well-known, and mature technologies. Therefore, their electrical connection relationships and specific circuit structures will not be elaborated here.
