Description

Technical Field

[0001] This application relates to the field of warehousing and logistics technology, and in particular to a stealthy forklift robot. Background Technology

[0002] With the popularization of intelligent manufacturing in today's society, various types of logistics mobile robots are widely used in various occasions, such as using lurking forklift robots to transport materials in the work area.

[0003] A stealth forklift robot typically consists of a frame and fork assembly. The frame has a fork receiving slot to accommodate the fork assembly and can move the fork assembly. The fork assembly can lift, extend, and retract to pick up materials. When the frame moves the fork assembly, it is usually hung on a bracket on the side wall of the fork receiving slot, keeping the fork assembly suspended to reduce friction with the ground when the stealth forklift robot moves on the ground. When the stealth forklift robot moves to the receiving point, the lifting mechanism of the fork assembly lowers the bottom plate to the ground and lifts the top plate, causing the top plate to detach from the bracket on the side wall. Then, the entire fork assembly moves outward towards the fork receiving slot, aligning the clearance groove of the fork assembly with the bracket. The top plate is then lowered, and during the descent, the bracket passes through the clearance groove to avoid impact with the top plate. Finally, the entire fork assembly extends out of the fork receiving slot and reaches under the material to receive it. In the prior art, when the fork assembly is attached to the rack, the large gap between the fork assembly and the inner wall of the fork receiving slot causes the fork assembly to shift significantly when the fork robot rotates, moves laterally, or vibrates. This can lead to problems such as the fork assembly colliding with the side wall of the fork receiving slot, falling off the rack, or interfering with the slide rail or other structures in the fork receiving slot after falling. Utility Model Content

[0004] The purpose of this application is to provide a stealthy forklift robot to solve the problem that the fork assembly will shift significantly within the fork receiving groove when the stealthy forklift robot rotates, moves laterally, or vibrates. The specific technical solution is as follows:

[0005] This application provides a stealthy forklift robot, which includes: a mobile frame, a fork leg assembly, and a first limiting member; the mobile frame has a fork leg receiving groove for accommodating the fork leg assembly, and brackets are respectively provided on the side walls on both sides of the fork leg receiving groove. When the fork leg assembly is in a retracted state, the brackets can support the fork leg assembly; the first limiting member is disposed on the side walls on both sides of the fork leg receiving groove and protrudes from the side walls, at least partially located above the brackets, for limiting the displacement of the fork leg assembly carried on the brackets along a first direction, the first direction being a horizontal direction perpendicular to the horizontal extension and retraction direction of the fork leg assembly.

[0006] In some embodiments, the side of the first limiting member closest to the first axis of the fork leg receiving groove is an inclined surface, and the distance between the inclined surfaces of the first limiting members on both sides gradually narrows from top to bottom. The inclined surface can guide the fork leg assembly when the fork leg assembly falls. The first axis is the central axis of the fork leg receiving groove parallel to the telescopic direction.

[0007] In some embodiments, the first limiting member includes a connecting portion and a guiding portion; one end of the connecting portion is connected to the side wall of the fork leg receiving groove, and the other end extends toward the first axis and is fixedly connected to one end of the guiding portion, wherein the side of the guiding portion near the first axis is the inclined surface.

[0008] In some embodiments, a support member is provided on the bottom wall of the fork leg receiving groove. The support member is used to assist in supporting one end of the fork leg assembly near the bottom wall of the fork leg receiving groove. The support member is also provided with a second limiting member. The top area of ​​the second limiting member protrudes from the top surface of the support member. A limiting fitting hole is provided at one end of the fork leg assembly near the bottom wall of the fork leg receiving groove. The top area of ​​the second limiting member can extend into the limiting fitting hole.

[0009] In some embodiments, the top region of the second limiting member is conical or frustum-shaped.

[0010] In some embodiments, the hanger is integrally formed with the first limiting member and fixedly connected to the side wall.

[0011] In some embodiments, the hanger and the first limiting member are detachably connected to the side wall of the fork leg receiving groove via connectors.

[0012] In some embodiments, the second limiting member is integrally formed with the support member, or the second limiting member is detachably connected to the support member.

[0013] In some embodiments, the upper surface of the bracket has an arcuate surface, and the fork leg assembly has a mounting groove that mates with the arcuate surface of the bracket.

[0014] In some embodiments, the top of the hanger is provided with a cushioning elastic element.

[0015] The lurking forklift robot provided in this application embodiment has a first limiting member that is disposed on the side walls on both sides of the fork leg receiving groove and protrudes from the side walls. Therefore, the first limiting member can block the fork leg assembly hanging on the bracket, limit the displacement of the fork leg assembly carried on the bracket along the first direction, and thus limit the offset range of the fork leg assembly. Therefore, it can solve the problem that the fork leg assembly has a large offset in the fork leg receiving groove when the lurking forklift robot rotates, moves laterally or vibrates.

[0016] Of course, any product implementing this application does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0033] This application provides a stealthy forklift robot, such as Figures 1 to 4 As shown, Figure 1 An axonometric view of the forklift robot provided in this application embodiment, showing the fork assembly attached to the bracket; Figure 2 for Figure 1 The image shows an axonometric view of the forklift assembly in the lurking forklift robot detaching from the rack and descending. Figure 3 for Figure 2 The image shows a magnified view of the lurking forklift robot at point A. Figure 4 for Figure 3This is a schematic diagram from another angle of the enlarged partial view; the lurking forklift robot includes: a mobile frame 10, a fork leg assembly 20, and a first limiting member 30; the mobile frame 10 has a fork leg receiving groove 11 for accommodating the fork leg assembly 20, and hangers 13 are respectively provided on the side walls 121 on both sides of the fork leg receiving groove 11. When the fork leg assembly 20 is in a retracted state, the hangers 13 can support the fork leg assembly 20; the first limiting member 30 is disposed on the side walls 121 on both sides of the fork leg receiving groove 11 and protrudes from the side walls 121. At least a portion of the first limiting member 30 is located above the hangers 13 and is used to limit the displacement of the fork leg assembly 20 carried on the hangers 13 along the first direction Y, where the first direction Y is a direction perpendicular to the horizontal extension and retraction direction X of the fork leg assembly 20 in the horizontal direction.

[0034] In this embodiment, since the first limiting member 30 is disposed on the sidewalls 121 on both sides of the fork leg receiving groove 11 and protrudes from the sidewalls 121, the first limiting member 30 can block the fork leg assembly 20 hanging on the bracket 13, and can limit the displacement of the fork leg assembly 20 carried on the bracket 13 along the first direction Y, thereby limiting the offset range of the fork leg assembly 20. Therefore, it can solve the problem that the fork leg assembly 20 has a large offset in the fork leg receiving groove 11 when the lurking forklift robot rotates, moves laterally or vibrates, thereby making the lurking forklift robot more stable when moving.

[0035] Specifically, there is at least one set of hangers. When there are multiple sets of hangers, there are also multiple sets of first limiting members 30. Multiple sets of hangers can be arranged at intervals along the telescopic direction X on the side wall of the fork leg receiving groove. Multiple sets of first limiting members 30 are located above different hangers.

[0036] More specifically, when the fork assembly is located in the middle of the fork receiving groove without tilting, the distance between the position of the first limiting member closest to the fork assembly and the fork assembly is very small. This application does not limit this distance and it can be set according to actual processing requirements.

[0037] It should be noted that the mobile frame 10, as the main support structure of the lurking forklift robot, is capable of overall movement such as rotation, lateral movement, and straight-line travel; specifically, for example... Figure 1 and Figure 2 , Figure 5 As shown, Figure 5 for Figure 1The diagram shows an axonometric view of the top plate of the forklift assembly in the lurking forklift robot when it is raised. The mobile frame 10 has a frame drive wheel 101, which can drive the mobile frame 10 to move in all directions. The forklift assembly 20 includes a forklift body 21 and a forklift drive wheel 22. The forklift drive wheel 22 can drive the forklift body 21 to reciprocate. The forklift body 21 includes a base plate 211, a lifting drive device 212, and a top plate 213. The lifting drive device 212 is used to drive the base plate 211 and the top plate 213 to move closer or further apart along the height direction Z. The top plate 213 has clearance grooves 2131 on both sides. Figure 1 , Figures 6 to 8 As shown, Figure 6 for Figure 5 The fork-leg assembly shown is a front view when it is attached to the bracket. Figure 7 for Figure 6 The side view shown is of the fork-leg assembly attached to the bracket. Figure 8 for Figure 6 The diagram shows a top view of the fork assembly when it is attached to the bracket. When the fork assembly 20 is in the retracted state, it is located in the fork receiving groove 11 of the mobile frame 10. The top plate 213 of the fork assembly 20 is attached to the bracket 13, which supports the fork assembly 20, thus suspending it in the air and reducing friction between the fork assembly 20 and the ground when the mobile frame 10 moves it. Figure 2 , Figures 9 to 11 As shown, Figure 9 for Figure 5 The front view of the fork-leg assembly after the top plate is raised and the bottom plate is lowered; Figure 10 for Figure 9 Side view of the fork-leg assembly after the top plate is raised and the bottom plate is lowered; Figure 11 for Figure 9 The diagram shows a top view of the forklift assembly with its top plate raised and bottom plate lowered. When goods need to be picked up, the lifting drive device 212 of the forklift assembly 20 first lowers the bottom plate 211 to the moving surface, then raises the top plate 213 so that it can detach from the hanger 13. The forklift assembly 20 is then moved towards the outside of the forklift receiving groove 11, aligning the clearance groove 2131 of the forklift assembly 20 with the hanger 13. The top plate 213 is then lowered, and during this descent, the hanger 13 passes through the clearance groove 2131 to prevent it from impacting the top plate 213. Finally, the forklift assembly 20 extends out of the forklift receiving groove 11 and into the bottom of the material to receive it.

[0038] Furthermore, such as Figure 3As shown, the side of the first limiting member 30 closest to the first axis of the fork leg receiving groove 11 is an inclined surface 301. The distance between the inclined surfaces 301 of the first limiting members 30 on both sides of the fork leg receiving groove gradually narrows from top to bottom. The inclined surface 301 can guide the fork leg assembly 20 when it falls. The first axis is the central axis of the fork leg receiving groove 11 parallel to the telescopic direction X.

[0039] In other embodiments, the side of the first limiting member 30 near the first axis of the fork leg receiving groove 11 may also be a vertical surface, that is, perpendicular to the movement surface of the moving frame 10.

[0040] It should be noted that "the fork assembly 20 falling from above the bracket 13" specifically refers to the top plate 213 of the fork assembly 20 falling from above the bracket 13. When the top plate of the fork assembly 20 falls from above the bracket 13, the inclined surface 301 can contact the corresponding side of the top plate 213 of the fork assembly 20, guiding the falling path of the top plate 213 and ensuring that the top plate falls accurately to the preset position on the bracket 13.

[0041] Furthermore, the first limiting member 30 includes a connecting portion 31 and a guide portion 32. One end of the connecting portion 31 is connected to the side wall 121 of the fork leg receiving groove 11, and the other end extends towards the first axis and is fixedly connected to one end of the guide portion 32. The side of the guide portion 32 closest to the first axis is an inclined surface 301. The connecting portion 31 achieves a stable connection between the first limiting member 30 and the side wall 121, and the inclined surface 301 of the guide portion 32 guides the fork leg assembly 20. The structure is simple and highly reliable. Specifically, the connecting portion 31 can be fixed to the side wall 121 by bolts, welding, etc., and the guide portion 32 and the connecting portion 31 can be integrally formed, such as by casting, forging, or welding, to ensure structural strength.

[0042] In other embodiments, the other end of the connecting part 31 may be detachably connected to one end of the guide part 32 so as to replace the guide part 32 with different specifications according to different specifications of fork leg assemblies.

[0043] Based on all the above embodiments, such as Figure 2 , Figure 5 and Figure 11 , Figure 12 As shown, Figure 12 for Figure 2The diagram shows a partial enlarged view of point B in the lurking forklift robot. A support member 14 is provided on the bottom wall 122 of the fork leg receiving groove 11. The support member 14 assists in supporting the end of the fork leg assembly 20 near the bottom wall 122 of the fork leg receiving groove 11. A second limiting member 15 is also provided on the support member 14. The top region 151 of the second limiting member 15 protrudes from the top surface of the support member 14. A limiting fitting hole 201 is provided at the end of the fork leg assembly 20 near the bottom wall 122 of the fork leg receiving groove 11, and the top region 151 of the second limiting member 15 can extend into the limiting fitting hole 201. The support member 14 assists in supporting the end of the fork leg assembly 20 near the bottom wall 122 when the fork leg assembly 20 falls, thereby distributing the load on the bracket 13 and improving structural stability. The inner diameter of the limiting fitting hole 201 is slightly larger than the maximum outer diameter of the top region 151 of the second limiting member 15. When the fork assembly 20 falls onto the support member 14, the top area 151 of the second limiting member 15 can extend into the limiting mating hole 201, and restrict the displacement of the fork assembly 20 in the horizontal direction (including the displacement in the first direction Y and the telescopic direction X) through the hole-shaft mating, further preventing the fork assembly 20 from deviating.

[0044] In other embodiments, the support member 14 may not be provided, and the number of hangers 13 may be multiple. At least two of the multiple hangers 13 are provided at the end of the side wall 121 of the fork leg receiving groove 11 near the bottom wall 122, so as to improve the structural stability.

[0045] Furthermore, such as Figure 5 and Figure 11 , Figure 12 As shown, the top region 151 of the second limiting member 15 is conical or frustum-shaped. Through this conical or frustum-shaped top structure, during the descent of the fork assembly 20, the guiding effect of the conical surface guides the limiting mating hole 201 and the second limiting member 15 to precise alignment, reducing alignment difficulties caused by assembly errors or offsets, and ensuring that the second limiting member 15 can smoothly extend into the limiting mating hole 201. This application does not limit the taper of the cone or frustum.

[0046] In some other embodiments, the top region 151 of the second limiting member 15 may also be cylindrical. This application does not limit the shape of the second limiting member 15.

[0047] Furthermore, the second limiting member 15 and the support member 14 can be configured according to actual installation and maintenance needs. The second limiting member 15 and the support member 14 can be integrally formed, or they can be detachably connected. Integral forming, such as casting or forging, can improve the connection strength between the second limiting member 15 and the support member 14; detachable connection, such as threaded connection or bolt connection, facilitates the individual replacement of the second limiting member 15. A suitable connection method can be selected according to actual needs.

[0048] Specifically, the support member 14 can be a rectangular block with mounting holes. Part of the second limiting member is installed within these mounting holes. More specifically, the second limiting member can be a guide pin. Even more specifically, the support member 14 can be detachably connected to the bottom wall of the fork leg receiving groove using fasteners such as screws or bolts. Figure 12 As shown, the fastener connection holes on the support member 14 can be set on both sides of the guide pin mounting hole.

[0049] Based on all the above embodiments, the connection method between the hanger 13 and the first limiting member 30 can be selected according to processing and maintenance requirements. In some embodiments, the hanger 13 and the first limiting member 30 are integrally formed and fixedly connected to the side wall 121. Specifically, they can be manufactured using integral forming processes such as casting and forging, and then fixed to the side wall 121 by bolts, welding, etc., which can improve the connection strength between the hanger 13 and the first limiting member 30 and reduce assembly errors. In other embodiments, the hanger 13 and the first limiting member 30 are detachably connected to the side wall 121 of the fork leg receiving groove 11 through connectors. It should be noted that the form of the connector can be selected according to actual installation requirements, for example, such as Figure 3 and Figure 4 As shown, the bracket 13 can be connected to the side wall 121 of the fork leg receiving groove 11 via the first connector 16, and the first limiting member 30 can be connected to the side wall 121 of the fork leg receiving groove 11 via the second connector 17; the mobile frame 10 is provided with a mounting groove 102, which is located on the first side of the side wall 121. The two ends of the first connector 16 along the extension direction X are fixedly connected to the mounting groove 102 via the first fastener 162. The first connector 16 has a connecting groove 161, and one end of the bracket 13 is fixedly connected to the connecting groove 161. Inside 61, the other end passes through the second side of the sidewall 121 and extends towards the fork leg receiving groove 11; the second connector 17 is located on the side of the first connector 16 near the sidewall 121, and is fixedly connected to the first side of the sidewall 121 by the second fastener 172. The second connector 17 has a clearance hole 171 for avoiding the hanger 13. The first limiting member 30 is fixedly connected to the top of the second connector 17. The detachable connection facilitates the maintenance and replacement of the hanger 13 or the first limiting member 30 in the future, reducing maintenance costs. Specifically, the first fastener 162 and the second fastener 172 can be bolts, screws, etc.

[0050] Based on all the above embodiments, such as Figures 3 to 5As shown, the upper surface of the bracket 13 has an arc surface, and the fork assembly 20 has a mounting groove 202 that mates with the arc surface of the bracket 13. The inner surface of the mounting groove 202 is a curved surface adapted to the arc surface. Through the mating of the arc surface and the curved surface, stress concentration when the bracket 13 and the fork assembly 20 come into contact can be reduced, reducing wear caused by long-term contact. At the same time, it provides a certain degree of cushioning when the fork assembly 20 shakes slightly, avoiding rigid collisions.

[0051] In some other embodiments, the upper surface of the hanger 13 may also be a plane, and this application does not limit the shape of the hanger 13.

[0052] Based on all the above embodiments, the top of the bracket 13 is provided with a buffer elastic element (not shown). The buffer elastic element can be made of elastic materials such as nitrile rubber and polyurethane. The buffer elastic element can absorb the impact force when the fork leg assembly 20 is attached and the vibration during the movement process, further reducing the shaking of the fork leg assembly 20, improving the stability of the attachment state, and reducing noise.

[0053] In some other embodiments, the top of the bracket 13 may not be provided with a buffer elastic element, that is, the top of the bracket 13 directly contacts the fork leg assembly 20.

[0054] Based on all the above embodiments, such as Figure 1 and Figure 2 As shown, a photoelectric sensor 23 can be provided at one end of the bottom wall 122 of the fork assembly 20 away from the fork receiving groove 11. The photoelectric sensor 23 can be used to detect materials or obstacles in front of the fork assembly 20, providing signal reference for the extension and movement of the fork assembly 20, thereby improving the safety and accuracy of the lurking forklift robot operation. It should be noted that the support member 14, the buffer elastic member, and the photoelectric sensor 23 can be set simultaneously, or any combination of several can be set, or only one of them can be selected for setting.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
