Description

Technical Field

[0001] This utility model relates to the technical field of guide wheel installation and positioning, and specifically to a guide wheel installation structure, chassis mechanism and transport vehicle. Background Technology

[0002] In logistics handling equipment (such as AGV trolleys, rail transport trolleys, etc.), guide wheels are the core guiding and load-bearing components. The reliability, adjustability and adaptability of their installation structure directly affect the operational stability and lifespan of the equipment.

[0003] In existing technology, guide wheels are usually fixed to one side of the chassis by a mounting base. They can abut against the guide rail and roll along the guide rail to provide rolling support for the chassis. Usually, in order to adapt to guide rails of different heights, the mounting base needs to be removed and the height of the guide wheel is adjusted by adjusting the height of the mounting base. This results in a large area needing to be reserved on the chassis for the height adjustment of the mounting base, which affects the overall compactness of the pallet truck. Utility Model Content

[0004] This utility model addresses the aforementioned problems and aims to provide a guide wheel mounting structure, chassis mechanism, and transport vehicle. The wheel body can be adjusted vertically on the mounting base via the mounting shaft, making it suitable for guide rails of different heights. Furthermore, it eliminates the need to reserve adjustment space for the mounting base on the chassis, resulting in a more compact overall structure.

[0005] To achieve the above objectives, this utility model provides a guide wheel mounting structure, comprising:

[0006] The mounting base has a positioning hole and an adjustment gap. The positioning hole passes through two opposite sides of the mounting base. The adjustment gap is located on one side of the positioning hole and is used to adjust the size of the positioning hole. When the width of the adjustment gap increases, the positioning hole can be enlarged. When the width of the adjustment gap decreases, the positioning hole can be reduced.

[0007] The guide wheel includes a wheel body and a mounting shaft. The wheel body is fixed to one end of the mounting shaft, and the other end of the mounting shaft away from the wheel body can be inserted into the positioning hole.

[0008] When the width of the adjustment gap is less than or equal to the preset value, the mounting shaft is in a locked state, and the inner wall of the positioning hole can fit against the outer wall of the mounting shaft to lock the mounting shaft.

[0009] When the width of the adjustment gap is greater than a preset value, the mounting shaft is in an unlocked state, and the inner wall of the positioning hole can be separated from the outer wall of the mounting shaft to unlock the mounting shaft.

[0010] According to the guide wheel mounting structure described above, the adjustment gap extends through the two opposite sides of the mounting base along the axial direction of the positioning hole and communicates with the positioning hole.

[0011] According to the guide wheel mounting structure described above, the mounting base includes a first clamping member and a second clamping member that are integrally formed or separately formed. The first clamping member and the second clamping member surround and form the positioning hole, and the adjustment gap is located between the first clamping member and the second clamping member.

[0012] The guide wheel mounting structure described above further includes a first locking structure, which includes a first locking bolt. The first locking bolt passes between the first clamping member and the second clamping member and is threadedly connected to the first clamping member or the second clamping member. The width of the adjustment gap can be adjusted by rotating the first locking bolt.

[0013] According to the guide wheel mounting structure described above, one end of the first clamping member is provided with a first threaded hole, and one end of the second clamping member is provided with a first through hole communicating with the first threaded hole. The first locking bolt can be inserted into the communicating hole between the first through hole and the first threaded hole, and the threaded part of the first locking bolt can be threadedly engaged with the first threaded hole. The nut part of the first locking bolt can abut against the outer side of the second clamping member.

[0014] According to the guide wheel mounting structure described above, when the first clamping member and the second clamping member are integrally formed, the adjustment gap is set to one. One end of the first clamping member is provided with a first abutting surface, and one end of the second clamping member is provided with a second abutting surface corresponding to the first abutting surface. The first abutting surface and the second abutting surface together form the adjustment gap.

[0015] According to the guide wheel mounting structure described above, when the first clamping member and the second clamping member are separately formed, the adjustment gap is set to two. The first clamping member has a first abutting surface at both ends, and the second clamping member has a second abutting surface at both ends corresponding to the two first abutting surfaces. The two first abutting surfaces and the two second abutting surfaces together form the two adjustment gaps.

[0016] The guide wheel mounting structure described above further includes a second locking structure, which includes a second locking bolt. The other end of the first clamping member is provided with a second threaded hole, and the other end of the second clamping member is provided with a second through hole communicating with the second threaded hole. The second locking bolt can be inserted into the communicating hole between the second through hole and the second threaded hole, and the threaded part of the second locking bolt can be threadedly engaged with the second threaded hole. The nut part of the second locking bolt can abut against one side of the second clamping member.

[0017] A chassis mechanism, comprising:

[0018] Chassis main body;

[0019] As described above, in the guide wheel mounting structure, one end of the mounting base is provided with a positioning plate, and the mounting base is fixedly connected to the chassis body through the positioning plate.

[0020] A transport vehicle, comprising:

[0021] The chassis mechanism as described above;

[0022] The frame mechanism is located above the chassis mechanism.

[0023] This utility model has the following beneficial effects:

[0024] 1. The size of the positioning hole can be adjusted by changing the gap, thereby enabling the clamping and release of the mounting shaft. When the mounting shaft is in the unlocked state, it can move up and down along the positioning hole, thereby driving the guide wheel to adjust its position up and down. There is no need to move the mounting base or reserve adjustment space on the chassis, making the overall structure more compact.

[0025] 2. The adjustment gap is formed by the first clamping member and the second clamping member. The width of the adjustment gap can be adjusted by rotating the first locking bolt, which makes the operation more convenient and makes locking and unlocking the mounting shaft easier.

[0026] 3. The first clamping component and the second clamping component are integrally formed, which is convenient for forming. Attached Figure Description

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] Example 1

[0034] like Figure 1-2 As shown, a guide wheel mounting structure includes a mounting base 100 and a guide wheel 200. The guide wheel 200 is vertically and heightably mounted on the mounting base 100. The height of the guide wheel 200 can be adjusted to suit guide rails of different heights, thereby improving the applicability of the guide wheel 200. That is, one guide wheel 200 can be used for guide rails of various different heights.

[0035] Specifically, the mounting base 100 is provided with a positioning hole 110 and an adjustment gap 120. The positioning hole 110 penetrates through the two opposite sides of the mounting base 100. In this embodiment, the positioning hole 110 is arranged vertically and penetrates the upper and lower sides of the mounting base 100. The adjustment gap 120 is located on one side of the positioning hole 110 and is used to adjust the size of the positioning hole 110. When the width of the adjustment gap 120 increases, the positioning hole 110 can be enlarged; when the width of the adjustment gap 120 decreases, the positioning hole 110 can be reduced. The guide wheel 200 includes a wheel body 210 and a mounting shaft 220. The wheel body 210 is fixed to... One end of the mounting shaft 220, and the other end of the mounting shaft 220 away from the wheel body 210, can be inserted into the positioning hole 110. The mounting shaft 220 is locked by the side wall of the positioning hole 110 wrapping around it. Due to the adjustability of the positioning hole 110, the mounting shaft 220 can be locked and unlocked. When the mounting shaft 220 is in the unlocked state, its position in the positioning hole 110 can be adjusted, thereby adjusting the height of the wheel body 210 to suit guide rails of different heights without replacing the guide wheel 200. When the mounting shaft 220 is in the locked state, the wheel body 210 is fixed and can perform corresponding guiding work.

[0036] In this embodiment, the wheel body 210 is fixed to the lower end of the mounting shaft 220, and the upper end of the mounting shaft 220 passes through the positioning hole 110.

[0037] In this embodiment, when the width of the adjustment gap 120 is less than or equal to a preset value, the mounting shaft 220 is in a locked state, and the inner wall of the positioning hole 110 can fit against the outer wall of the mounting shaft 220 to lock the mounting shaft 220. When the width of the adjustment gap 120 is greater than the preset value, the mounting shaft 220 is in an unlocked state, and the inner wall of the positioning hole 110 can separate from the outer wall of the mounting shaft 220 to unlock the mounting shaft 220. The preset value is determined by the size of the mounting shaft 220 and the positioning hole 110.

[0038] Furthermore, the adjustment gap 120 extends through the axial direction of the positioning hole 110 to the opposite sides of the mounting base 100. Taking the positioning hole 110 as an example where it is arranged in the vertical direction, the adjustment gap 120 extends through the upper and lower sides of the mounting base 100. Moreover, the adjustment gap 120 is connected to the positioning hole 110. When the width of the adjustment gap 120 changes, it can drive the inner wall of the positioning hole 110 to move, thereby realizing the adjustment of the size of the positioning hole 110.

[0039] Of course, in addition to penetrating the two opposite sides of the axial mounting seat 100 along the positioning hole 110, the adjustment gap 120 also penetrates the mounting seat 100 on the radial side of the positioning hole 110, which allows one side of the positioning hole 110 to communicate with the outside, making it convenient to adjust the width of the adjustment gap 120.

[0040] Furthermore, in this embodiment, the mounting base 100 includes an integrally formed first clamping member 130 and a second clamping member 140. The first clamping member and the second clamping member 140 together form a positioning hole 110. The adjustment gap 120 is located between the first clamping member 130 and the second clamping member 140. In this embodiment, since the first clamping member 130 and the second clamping member 140 are integrally formed, it is only necessary to open a gap between the first clamping member 130 and the second clamping member 140 that meets the above conditions. This gap can form the adjustment gap 120, and only one adjustment gap 120 is required. The adjustment gap 120 can be adjusted by driving the first clamping member 130 and the second clamping member 140 to move closer to or further away from each other.

[0041] Of course, in this embodiment, the first clamping member 130 and the second clamping member 140 need to be made of a material with a certain elasticity to allow the first clamping member 130 and the second clamping member 140 to deform, thereby realizing the adjustment of the positioning hole 110 and the adjustment gap 120.

[0042] Furthermore, in order to drive the first clamping member 130 and the second clamping member 140, the guide wheel 200 mounting structure also includes a first locking structure. The first locking structure includes a first locking bolt, which passes between the first clamping member 130 and the second clamping member 140 and is threadedly connected to the first clamping member 130 or the second clamping member 140. In this embodiment, when the first locking bolt rotates, it can drive the first clamping member 130 or the second clamping member 140 to perform horizontal displacement, thereby realizing the adjustment of the width of the adjustment gap 120.

[0043] Furthermore, to keep the mounting shaft 220 in a locked state, the first clamping member 130 and the second clamping member 140 need to be held in a preset position. One end of the first clamping member 130 has a first threaded hole 131, and one end of the second clamping member 140 has a first through hole 141 communicating with the first threaded hole 131. The first locking bolt can be inserted into the communicating hole between the first through hole 141 and the first threaded hole 131, and the threaded portion of the first locking bolt can engage with the threaded portion of the first threaded hole 131. The nut portion of the first locking bolt can also engage with the first threaded portion of the first threaded hole 141. One side of the clamping member 130 abuts against the first locking screw. Taking the first clamping member 130 moving towards the side closer to the second clamping member 140 as an example, when the first locking screw is rotated, the first clamping member 130 is driven by the first locking screw to move towards the side closer to the second clamping member 140. The second clamping member 140 will be affected by the nut part and will also move towards the side closer to the first clamping member 130, thereby reducing the width of the adjustment gap 120. When the positioning hole 110 is reduced to clamp the mounting shaft 220, the first locking screw can no longer rotate in that direction.

[0044] In this embodiment, a chassis mechanism includes a chassis body and a guide wheel 200 mounting structure as described above. One end of the mounting base 100 is provided with a positioning plate 150, and the mounting base 100 is fixedly connected to the chassis body through the positioning plate 150. The positioning plate 150 is provided with a plurality of first positioning pin holes, and the chassis body is provided with a plurality of second positioning pin holes. The plurality of first positioning pin holes and the plurality of second positioning pin holes correspond one-to-one, and positioning pins can be inserted into the connecting holes of the first positioning pin holes and the second positioning pin holes to achieve positioning.

[0045] In this embodiment, a transport vehicle includes a chassis mechanism and a frame mechanism, with the frame mechanism located above the chassis mechanism. The chassis mechanism is used to provide movable support for the frame mechanism.

[0046] In this embodiment, a guide wheel 200 mounting structure, a chassis mechanism, and a transport vehicle are disclosed. The guide wheel 200 mounting structure includes a mounting base 100 and a guide wheel 200. The mounting base 100 has a positioning hole 110 and an adjustment gap 120. The positioning hole 110 penetrates both opposite sides of the mounting base 100. The adjustment gap 120 is located on one side of the positioning hole 110 and is used to adjust the size of the positioning hole 110. When the width of the adjustment gap 120 increases, the positioning hole 110 can be enlarged; when the width of the adjustment gap 120 decreases, the positioning hole 200 can be... The guide wheel 200 includes a wheel body 210 and a mounting shaft 220. The wheel body 210 is fixed to one end of the mounting shaft 220, and the other end of the mounting shaft 220 away from the wheel body 210 can be inserted into the positioning hole 110. The size of the positioning hole 110 can be controlled by adjusting the size of the gap 120, thereby locking and unlocking the mounting shaft 220. When the mounting shaft 220 is in the unlocked state, the height of the mounting shaft 220 can be adjusted, thereby adjusting the height of the wheel body 210 to suit guide rails of different heights. The adjustment is also relatively convenient.

[0047] Example 2

[0048] In this embodiment, unlike in embodiment one, the first clamping member and the second clamping member are formed separately, that is, the first clamping member and the second clamping member are independent of each other. In this forming method, there are two adjustment gaps. The first clamping member has a first abutment surface at both ends, and the second clamping member has a second abutment surface at both ends corresponding to the two first abutment surfaces. The two first abutment surfaces and the two second abutment surfaces together form two adjustment gaps, and the positioning hole can be adjusted by adjusting the two adjustment gaps.

[0049] In this embodiment, since there are two adjustment gaps, in addition to the first locking structure adjusting one of the adjustment gaps, a second locking structure should also be provided. The second locking structure is used to adjust the other adjustment gap. The second locking structure includes a second locking bolt. The other end of the first clamping member is provided with a second threaded hole, and the other end of the second clamping member is provided with a second through hole communicating with the second threaded hole. The second locking bolt can be inserted into the communicating hole between the second through hole and the second threaded hole, and the threaded part of the second locking bolt can be threadedly engaged with the second threaded hole. The nut part of the second locking bolt can abut against one side of the second clamping member.
