Description
Technical Field
[0001] The utility model belongs to the technical field of shuttle vehicles, and in particular relates to a guide device for a shuttle vehicle. Background Art
[0002] In the daily operations of warehousing and logistics, more and more factories are using integrated automation systems that combine shuttles with shelves to replace traditional warehousing and logistics operations, and the four-way shuttle system is particularly outstanding for its higher construction economy.
[0003] The guide wheels of the shuttle are generally fixed around the body of the vehicle. After being fixed, the gap between the guide wheels and the track is fixed. When the parallelism of the long track is not high, the shuttle will swing along the track surface. When the long track is used for a long time, the long track will have ups and downs and the joints will be misaligned. The guide wheels will collide with the misaligned track without buffering, affecting the operation and stability of the track.
[0004] In addition, when a manual forklift places the shuttle on the track, it is difficult for the manual forklift to place the shuttle because the gap between the guide wheel and the track is designed to be only 2-3mm on one side. When the error is large, the guide wheels of the shuttle may be mounted on the track one or more times, affecting the safety of the shuttle's manual lane change. In this case, the shuttle relies on gravity to squeeze the track to enter, affecting the designed gap, which will cause the track end spacing to become larger in the long run. At the same time, the shuttle falls into the track due to the raised guide wheels, affecting the shuttle body hardware, and there is a risk of hardware damage. Utility Model Content

DETAILED DESCRIPTION
[0032] In order to more clearly illustrate the embodiments of the utility model and the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.
[0033] The utility model embodiment provides a guide device for a shuttle vehicle, see Figure 1-Figure 8 , including a bracket 1 arranged on the side wall of the shuttle 7 rail, a guide wheel 6, an elastic support body 5 and a sliding shaft 3 slidably mounted in the bracket 1, the guide wheel 6 is rotatably arranged on the sliding shaft 3 in the bracket 1, both ends of the sliding shaft 3 and the bracket 1 are supported by the elastic support body 5, and the elastic support body 5 elastically supports the sliding shaft 3 and the guide wheel 6 carried thereon toward the outside of the bracket 1.
[0034] In the present application, the two side walls of the shuttle 7 are rail side walls, such as Figure 7 , Figure 8 As shown in , a guide device is arranged on the side wall of the rail, and preferably four guide devices can be arranged.
[0035] In the embodiment of the present application, the guide wheel 6 and the side wall of the opposing rail are elastically supported and have a certain amount of expansion and contraction space. They perform well on uneven track surfaces and when vehicles enter the track, and can play a buffering role to a certain extent, reducing the impact force between the vehicle and the rail. When entering the track, the requirements for the assembly accuracy of the track are reduced, and entering the track can be implemented more conveniently.
[0036] In the present application, the specific structure of the bracket 1 can be a "U"-shaped structure, specifically including a base plate and two side plates, the two side plates are respectively arranged at the two ends of the same side of the base plate, the sliding shaft 3 is slidably mounted between the two side plates, and the guide wheel 6 is loaded between the two side plates and is located in the middle of the sliding shaft 3.
[0037] It is understandable that, during assembly, the guide wheel 6 can be placed between the two side plates first, and then the sliding shaft 3 can be inserted into the axis of the guide wheel 6. The guide wheel 6 can serve as an anti-falling part of the sliding shaft 3 without affecting the connection relationship between the sliding shaft 3 and the two side plates.
[0038] In a specific embodiment, the sliding connection between the sliding shaft 3 and the two side panels can be realized based on the slots opened on the side panels. The slots are through-type and strip-shaped. They can be placed in the middle of the side panels and opened in the horizontal direction. It should be noted that the slots on the two side panels should be opened at the same position and can be opened symmetrically, so that the sliding shaft 3 can slide smoothly in the hole without causing the structural stop tilting phenomenon. Based on the slots of the two side panels, the two ends of the sliding shaft 3 can correspond to a side panel respectively, and slide in the slots in a horizontal position perpendicular to the side panels.
[0039] In the present application, the sliding shaft 3 and the side plate are slidably connected, and the prerequisite for extension and retraction is met. An elastic support body 5 can be added between the sliding shaft 3 and the side plate so that the extension and retraction of the sliding shaft 3 can be reset; when the sliding shafts 3 on both sides have the resetting power at the same time, the vehicle body can be automatically centered, and the rolling abutment effect between the guide wheel 6 and the track surface is better.
[0040] In a feasible embodiment, an elastic support body 5 is provided on the side plate or in the slot, and the elastic support body 5 elastically supports the sliding shaft 3 toward the outside of the bracket 1, and the elastic support of the sliding shaft 3 includes pushing and pulling toward the outside.
[0041] Specifically, both ends of the sliding shaft 3 can pass through the slot, and an elastic support body 5 is set on the outer side of the side plate to elastically support the sliding shaft 3. Under the joint support of the two elastic support bodies 5 on the two side plates, the sliding shaft 3 can slide smoothly along the slot.
[0042] It is understandable that the elastic support body 5 elastically supports the sliding shaft 3 in at least two directions, namely, pushing outward and pulling outward. Limited by the length of the slot, when the guide device is suspended, the elastic support body 5 should be in a stressed state or just unstressed state; when in a stressed state, the degree of compression or stretching should be in a relatively light state.
[0043] Specifically, an elastic support body 5 can be arranged in the slot hole, and the elastic support body 5 and the sliding shaft 3 are still elastically supported. A guide rod can be arranged to limit the running direction of the sliding shaft 3. The elastic support body 5 can be arranged on the guide rod to realize elastic support for the sliding shaft 3. The power of the elastic support can be pushing or pulling outward.
[0044] It can be understood that no matter the elastic support body 5 is based on the side plate setting or the slot setting, elastic support for the sliding shaft 3 is necessary, and the support direction and running trend should be determined, that is, the guide wheel 6 is pushed or pulled toward the outside of the bracket 1.
[0045] In the embodiment of the present application, the installation between the sliding shaft 3 and the bracket 1 needs to be completed in cooperation with the elastic support body 5, so as to realize the elastic support of the guide wheel 6. In this process, for assembly considerations, the specific structural coordination of each component can be as follows:
[0046] The sliding shaft 3 includes a first sliding portion 31 , a second sliding portion 32 , and a loading portion 33 . The guide wheel 6 is mounted on the loading portion 33 . The first sliding portion 31 and the second sliding portion 32 are slidably disposed in the slots of the two side plates, respectively.
[0047] The slot hole includes a sliding hole 11 and an assembly hole 12. The sliding hole 11 is connected to the assembly hole 12. The assembly hole 12 is a round hole, and the sliding hole 11 is a strip-shaped long hole. The width of the sliding hole 11 is smaller than the diameter of the assembly hole 12. The sizes of the first sliding part 31 and the second sliding part 32 are consistent and match the width of the sliding hole 11. The size of the loading part 33 matches the size of the assembly hole 12, and the size of the loading part 33 is larger than the width of the sliding hole 11.
[0048] For example, the first sliding part 31 and the second sliding part 32 may be quadrangular prisms, and the loading part 33 may be a cylinder. The cross section of the quadrangular prism is rectangular, and the cross section of the cylinder is circular. The rectangle is at most inscribed in the circle. The guide wheel 6 may be assembled on the loading part 33 through a bearing or other structure. The diameter of the loading part 33 matches the inner diameter of the assembly hole 12. In this case, the sliding shaft 3 may directly pass through the assembly hole 12 and penetrate between the two side plates. After the installation is completed, the two sliding parts are pushed into the sliding hole 11, and the prism structure of the sliding part slides between the sliding walls of the sliding hole 11.
[0049] The elastic support body 5 elastically supports the two ends of the sliding shaft 3 in the sliding hole 11 so that the sliding shaft 3 can slide within the length range of the sliding hole 11 , and the telescopic stroke of the elastic support body 5 can match the sliding hole 11 .
[0050] For example, the sliding hole 11 is located in front of the assembly hole 12, and the elastic support body 5 pushes the sliding shaft 3 to the area where the sliding hole 11 is located, and when the elastic support body 5 is compressed to the limit, the sliding shaft 3 is still located in the sliding hole 11. This avoids the sliding shaft 3 from retreating into the assembly hole 12, which may cause the risk of falling off or getting stuck.
[0051] Regarding the arrangement of the elastic support body 5, the present application takes the installation thereof in conjunction with the side plate structure as an example for explanation.
[0052] In a specific embodiment, the outer sides of the two side panels are fixedly connected with a fixing seat 2, and the fixing seat 2 is provided with a concave sliding cavity corresponding to the slot hole, so that the first sliding part 31 and the second sliding part 32 pass through the slot hole and are respectively slid into the sliding cavities on both sides, and elastic support bodies 5 are respectively provided between the bottom of the sliding cavities on both sides and the first sliding part 31 and the second sliding part 32, so as to synchronously and elastically support the sliding shaft 3 toward the outer side of the bracket 1.
[0053] Exemplarily, the fixing seat 2 may include a sliding cavity and side wing plates arranged on both sides of the sliding cavity, and the side wing plates are fixed to the side plates of the bracket 1, and the opening positions and directions of the sliding cavity and the slots are made to correspond.
[0054] A bottom-sealing support body 22 is provided at the bottom of the sliding cavity, and the position of the bottom cover can correspond to the assembly hole 12 or be behind the assembly hole 12 to reserve sufficient assembly space, which is used to load the elastic support body 5; a guide shaft 21 is provided in the middle of the support body 22, and a first sliding hole 311 and a second sliding hole 312 are respectively opened on the first sliding part 31 and the second sliding part 32 corresponding to the guide shaft 21, so that the two ends of the sliding shaft 3 are respectively sleeved on the guide shafts 21 on both sides; the elastic support body 5 is sleeved on the guide shaft 21 and is located between the support body 22 and the sliding shaft 3.
[0055] In this embodiment, the elastic support body 5 can be a spring, which is sleeved on the guide shaft 21, with one end abutting against the support body 22 and the other end abutting against the end of the sliding shaft 3; for example, the spring arranged on the left side plate of the bracket 1 abuts against the first sliding part 31, and the spring arranged on the right side plate abuts against the second sliding part 32; the specifications and elastic forces of the springs on both sides are the same, so as to achieve synchronous support for the sliding shaft 3, synchronously drive the two ends to slide in the sliding hole 11, and realize the telescopic effect of the sliding shaft 3 when balancing the external force.
[0056] In the present application, the sliding stroke of the sliding shaft 3 is limited by the length of the sliding hole 11. The opening of the sliding hole 11 does not exceed the side plate, so that the sliding shaft 3 will be stopped and limited when it reaches the front end of the sliding hole 11; in this scenario, the front end position of the guide shaft 21 is at least flush with the front end position of the sliding hole 11, so that the sliding shaft 3 always slides on the guide shaft 21 and does not fall off. The assembly space between the sliding shaft 3 and the support body 22 should meet the installation requirements of the elastic support body 5, for example, the length of the assembly space should be greater than the maximum compression length of the spring and not less than the free length of the spring.
[0057] When a guide device of the present application is assembled on the shuttle vehicle 7, it also includes a mounting seat 4, which is an intermediate body. Figure 1 As shown, it is a right-angle structure, and the bottom plate of the bracket 1 is fixedly arranged on the mounting seat, which can be a rotating connection or a fixed connection. The guide device is fixed to the rail side wall of the shuttle vehicle 7 through the mounting seat 4.
[0058] The bracket 1 and the mounting seat 4 can be rotatably connected, and the bracket 1 itself can be an eccentric rotating bracket. Under the action of gravity, the guide wheel 6 is in a vertical state, and the vehicle body can be smoothly guided into the track 8. During horizontal operation, the guide wheel 6 can run smoothly along the track under the action of friction. When the track surface has ups and downs, the angle and extension amount can still be freely adjusted to achieve stable operation.
[0059] As a feasible embodiment, the guide wheel 6 may include a conductive design so that the static electricity in the vehicle can be introduced into the ground through the guide wheel 6, the track 8 and the shelf, which will reduce the risk of static electricity.
[0060] In the specific implementation process, please refer to Figure 8 As shown in the figure, the upper layer is the shuttle 7 suspended in the air, and the springs on both sides are in an uncompressed state, that is, suspended and not compressed; the middle layer is after the shuttle 7 enters the track, the guide wheels 6 on both sides are in contact with the track surface, and the springs are squeezed, that is, normal compression; the lower layer is when the shuttle 7 is on the track, and the springs fail, that is, failure compression; taking the spacing between the tracks 8 as L, the maximum distance between the guide wheels 6 on both sides of the shuttle 7 is (L+10) mm, corresponding to the suspended and uncompressed state; the minimum distance between the guide wheels 6 on both sides is (L-6) mm, and after the shuttle 7 is placed in the track, the spring is in a compressed state, with a single-sided compression of 5 mm to ensure stable contact between the guide wheel 6 and the track 8, corresponding to the normal compression state; the maximum single-sided compression is 8 mm, and in the case of spring failure, the guide wheel is still 3 mm away from the track surface and can still play a guiding role, corresponding to the failure compression state.
