Description

Technical Field

[0001] This application relates to the technical field of wheelset transfer fixtures, and particularly to a wheelset transfer bracket. Background Technology

[0002] During the maintenance of wheelsets on bullet trains and high-speed trains, the wheelsets usually need to be transported using wheelset transfer brackets.

[0003] In the existing technology, the storage and transportation of wheelsets are based on wooden pallets as the base support. During the operation, the wheelsets are first placed on the wooden pallets using a crane, and then the wooden pallets loaded with wheelsets are transported to the destination using a forklift. However, in the existing technology, wooden pallets cannot be adapted to the specifications of the wheelsets. When faced with wheelsets of different specifications, the height can only be adjusted by adding or removing wooden blocks to meet the placement requirements of the wheelsets. Furthermore, existing wooden pallets will be worn down during forklift transportation, causing wood chips to fall to the ground, affecting subsequent forklift operations and resulting in poor usability. In addition, worn wooden pallets will also scratch the surface of new wheelsets, affecting not only the appearance of the product but also potentially reducing its functionality and service life. Utility Model Content

[0004] This utility model provides a wheelset transfer bracket, which improves the ease of operation during the storage and transfer of wheelsets and reduces the risk of damage to new wheelsets.

[0005] This technology avoids rigid compression between wheelsets and the problem of sawdust obscuring ground markings during wheelset storage and transportation, thus improving work efficiency and environmental cleanliness.

[0006] To achieve the aforementioned objectives, this application adopts the following technical solution: A wheelset transfer bracket, comprising A support base, on which several sets of support platform mechanisms are provided, the support platform mechanisms being located near opposite ends of the support base. One end of the support base is also provided with a hinge frame, and the bottom of the support base is provided with several pads, with forklift bays formed between adjacent pads; and A support device is connected to the support base. The support device is connected to one end of the support base by flipping and folding. The support device includes a column-shaped support base, a locking sleeve sleeved on the outside of the column-shaped support base, and a support head mechanism connected to the top of the column-shaped support base. Hinges are respectively provided on the opposite side walls near the bottom of the column-shaped support base. The hinges cooperate with the hinge frame to realize the hinge connection between the column-shaped support base and the support base.

[0007] In some alternative embodiments, a set of support platform mechanisms includes two support platform mechanisms, which are respectively disposed on opposite sides of the bracket base. Each support platform mechanism includes a base and a support block disposed on the base. The support block cooperates with the base to form the support platform mechanism.

[0008] In some optional embodiments, the support base is further provided with several sets of support plate mechanisms, which are located between the support platform mechanisms.

[0009] In some alternative embodiments, a set of support plate mechanisms includes two support plate mechanisms, which are respectively disposed on opposite sides of the support base. Each support plate mechanism includes a base and a support plate disposed on the base, and the support plate cooperates with the base to form the support plate mechanism.

[0010] In some alternative embodiments, the locking sleeve has slots on its opposite side walls, the slots having the same shape as the hinge frame, and the slots engaging with the hinge frame.

[0011] In some optional embodiments, the side wall of the locking sleeve is further provided with a guide hole, and the side wall of the column support is further provided with a locking mechanism. The locking mechanism and the column support are connected by bolts. When locking by the locking mechanism, the locking mechanism passes through the guide hole, extends from the outer side wall of the locking sleeve to the column support, and is bolted to the column support.

[0012] In some alternative embodiments, the guide hole is shaped like an oblong hole.

[0013] In some optional embodiments, the top of the column support is provided with a connecting hole, and the support head mechanism includes a support rod and a support head connected to the support rod. One end of the support rod is connected to the support head, and the other end is connected to the column support through the connecting hole.

[0014] In some optional embodiments, the support rod is provided with a set of positioning bolts, which respectively limit the connection position between the support head and the support rod and the depth to which the support rod extends into the column support base through the connection hole.

[0015] In some alternative embodiments, a set of positioning bolts includes at least two positioning bolts, one of which positions the connection between the support head and the support rod, and the other positioning bolt positions the depth to which the support rod extends into the column support base through the connection hole.

[0016] The wheelset transfer bracket provided in this application has the following beneficial effects: In the technical solution adopted in this application, a wheelset transfer bracket, during daily operation, has a vertical column support seat in the support device, which supports the roller shaft of a single-sided wheelset through the support head on the support device, while the single-sided wheel is supported by the support platform mechanism and support plate mechanism away from the support device. When the single-sided wheelset does not need to be supported, the locking mechanism is manually turned to loosen the locking sleeve. Then, the locking sleeve is lifted upwards, and at the same time, the locking mechanism moves along the direction of the guide hole, and the slot disengages from the hinge frame to release the vertical locking of the column support seat. Finally, the column support seat acts as a hinge rod and hinge frame. The support device is folded down 90° towards the base of the bracket to complete its storage. Furthermore, when supporting single-sided wheelsets of different specifications, the height of the support head can be adjusted by turning the positioning bolts to adjust the length of the support rod extending into the connection hole. The shorter the length extending into the connection hole, the higher the support head, and vice versa. During transport, a forklift is used to move the transport bracket carrying the single-sided wheelset through the forklift positions formed between the pads. This improves the ease of operation during wheelset storage and transport, and also reduces the risk of damage to new wheelsets. Attached Figure Description

[0024] refer to Figure 1A wheelset transfer bracket includes a bracket base 10 and a support device 20 connected to the bracket base 10. The support device 20 is connected to one end of the bracket base 10 by flipping and folding. The surface and ends of the bracket base are trimmed and have no sharp corners.

[0025] Continue to refer to Figure 1 Please refer to them together. Figure 2 The support base 10 is provided with several sets of support platform mechanisms 11 and several sets of support plate mechanisms 12. Specifically, the support platform mechanisms 11 are close to the opposite ends of the support base 10, and the support plate mechanisms 12 are located between the support platform mechanisms 11. Each set of support platform mechanisms 11 includes two support platform mechanisms 11, which are respectively arranged on opposite sides of the support base 10. Similarly, each set of support plate mechanisms 12 includes two support plate mechanisms 12, which are respectively arranged on opposite sides of the support base 10. The support platform mechanism 11 includes a base 111 and a support block 112 disposed on the base 111. The support block 112 cooperates with the base 111 to form the support platform mechanism 11. The support plate mechanism 12 includes a base 121 and a support plate 122 disposed on the base 121. The support plate 122 cooperates with the base 121 to form the support plate mechanism 12. The support plate mechanism 12 is designed to increase the contact area between the support and the wheelset during the support process, thereby improving the stability of the forklift during loading and unloading. In addition, the support block 112 and the support plate 122 are made of plastic to avoid scratching the surface of the wheelset during support. The top of the support block and the corner that contacts the wheelset are chamfered at an angle of 45°. Specifically, the support blocks 112 in a set of support platform mechanisms 11 are opposite each other, and the chamfers on the support blocks are also opposite each other, thus forming a support posture for the bracket, which increases stability and improves the durability of the bracket during support. One end of the bracket base 10 is also provided with a hinge frame 13, which can be directly fixed to the support plate. One end of the support base 10 can also be fixed to the support base 10 by a support frame, as long as it does not cause interference during the folding process of the support device 20; the hinge frame 13 is rectangular in shape; the bottom of the support base 10 is also provided with several pads 14, and a forklift position 15 is formed between adjacent pads 14, so that the forklift can be inserted into the forklift position 15 through the working end of the forklift to transport the support or the support carrying a single-sided wheel pair. It should be noted that the pad is long and narrow, and its two ends can be without end caps or with end caps.

[0026] Continue to refer to Figure 1 Please refer to them together. Figure 3 , Figure 4 and Figure 5The support device 20 includes a column-shaped support base 21, a locking sleeve 22 sleeved on the outside of the column-shaped support base 21, and a support head mechanism 23 connected to the top of the column-shaped support base 21. Hinges 24 are respectively provided on opposite side walls near the bottom of the column-shaped support base 21. The hinges 24 cooperate with the hinge frame 13 to achieve hinge connection between the column-shaped support base 21 and the support base 10. Slots 221 are respectively provided on opposite side walls of the locking sleeve 22. The shape of the slots 221 is the same as that of the hinge frame 13. The slots 221 are sleeved with the hinge frame 13 to lock the angle of the column-shaped support base 21. In the locked state, the column-shaped support base 21 cannot be folded. The locking sleeve 22 is also provided with a guide hole 222 on its side wall. The guide hole 222 is oblong in shape. The column support 21 is also provided with a locking mechanism 25 on its side wall. The locking mechanism 25 is connected to the column support 21 by bolts. When locking by the locking mechanism 25, the locking mechanism 25 passes through the guide hole 222 from the outer side wall of the locking sleeve 22 to the column support 21 and is bolted to the column support 21. This achieves the locking mechanism 25 and the column support 21 clamping the locking sleeve 22, avoiding misoperation of the locking sleeve 22 and avoiding the risk of the wheelset falling off during storage.

[0027] Continue to refer to Figure 3 Please refer to them together. Figure 6The column-shaped support base 21 has a connecting hole 211 on its top. The support head mechanism 23 includes a support rod 231 and a support head 232 connected to the support rod 231. Specifically, one end of the support rod 231 is connected to the support head 232, and the other end is connected to the column-shaped support base 21 through the connecting hole 211. It should be noted that the connection between the support rod 231 and the column-shaped support base 21 through the connecting hole 211 can be either a plug-in connection or a threaded connection. In addition, the support position of the support head 232 includes, but is not limited to, an inverted triangular opening or an inverted trapezoidal opening, for supporting and contacting the wheelset. For different specifications of wheelsets, the support head 232 with an inverted triangular opening or an inverted trapezoidal opening with a suitable angle needs to be matched to meet the support requirements of different specifications of wheelsets and improve the stability of the contact. Furthermore, the surface of the support head 232 that contacts the wheelset is provided with a pad to avoid damage to the wheelset caused by rigid contact between the wheelset and the support head 232. The material includes, but is not limited to, plastic. The lifting range of the support head 232 is 376~526mm, and the support head 232 can also rotate 360°, thereby improving the convenience of operation when placing the wheelset on the bracket. In addition, a set of positioning bolts 26 are provided on the support rod 231. The set of positioning bolts 26 respectively limits the connection position between the support head 232 and the support rod 231 and the depth of the support rod 231 extending into the column-shaped support base 21 through the connection hole 211. Specifically, the set of positioning bolts 26 includes at least two positioning bolts 26. One positioning bolt 26 positions the connection position between the support head 232 and the support rod 231, and the other positioning bolt 26 positions the depth of the support rod 231 extending into the column-shaped support base 21 through the connection hole 211, thereby realizing the adjustment of the support height of the support head mechanism 23. This allows for adjusting the height of the support device 20 or folding down the support device 20 according to different wheelet specifications, thereby meeting the wheelet placement requirements.

[0028] To facilitate understanding, the working principle of this application is further described as follows: A wheelset transfer bracket, during daily operation, requires support for a single-sided wheelset. The column-shaped support base 21 in the support device 20 is in a vertical state, and the support head 232 on the support device 20 supports the roller shaft of the single-sided wheelset. The main support is provided by the support platform mechanism 11 located away from the support device 20, while the support plate mechanism 12 provides auxiliary support for the single-sided wheelset. The operation process involves manually rotating the support device 90° away from the bracket base 10, after which the locking sleeve 22 falls, and the slot 221 engages with the hinge frame 1. The three components work together to make the column support 21 vertical. At the same time, the locking mechanism 25 moves along the guide hole 222. Finally, by turning the locking mechanism 25, the locking sleeve 22 is fixed, so that the support device 20 remains vertical. Finally, when different specifications of single-sided wheels are supported by the bracket, in order to meet the usage requirements, if it is necessary to adjust the height of the support head 232, the length of the support rod 231 extending into the connection hole 211 can be adjusted by turning the positioning bolt 26. The shorter the length extending into the connection hole 211, the higher the height of the support head 232, and vice versa. When there is no need to support the single-sided wheelset, the locking mechanism 25 is manually turned to release the locking sleeve 22. Then, the locking sleeve 22 is lifted upward. At the same time, the locking mechanism 25 moves along the direction of the guide hole 222, and the slot 221 disengages from the hinge frame 13 to release the vertical locking of the column support 21. Finally, under the action of the hinge rod 24 and the hinge frame 13, the column support 21 is folded 90° towards the support base 10, and the positioning bolt is turned to retract the support rod 231 as much as possible into the storage space formed by the column support 211 corresponding to the connection hole 211, thus completing the storage of the support device 20. During transport, the working end of the forklift uses the forklift position 15 formed between its pads 14 to transport idle supports or supports carrying single-sided wheelsets. This allows the supports to be adjusted according to the specifications of different wheel sets during storage and transport, improving the convenience of operation. Furthermore, during the transport of supports carrying wheelsets by the forklift, the original wooden pallet is prevented from falling wood chips. In addition, the transport of supports in this application also effectively reduces the risk of damage to the surface of new wheelsets.
