Description

Technical Field

[0001] This utility model relates to the field of lifting equipment, specifically to a positioning auxiliary device for transferring train air conditioning modules. Background Technology

[0002] As a key component of rail vehicles, train air conditioning modules must be removed from the train and transferred to a specific testing and maintenance station using a special vehicle when they require regular maintenance, troubleshooting, or replacement and upgrades.

[0003] During this transfer process, it is necessary to tightly fasten the load-bearing fasteners on the special vehicle to the lifting lugs on the module to ensure the safety of handling and operation. Some existing special vehicles have sliding fasteners on their long side beams to fasten the side lifting lugs on the train air conditioning module.

[0004] Since the positions of the lifting lugs of different models or batches of air conditioning modules may vary, operators need to adjust the positions of these fasteners to accommodate different air conditioning modules.

[0005] Adjusting the position of the fasteners often requires a crane to lift or suspend the air conditioning module, which makes the adjustment process extremely cumbersome, time-consuming, and poses safety hazards. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning auxiliary device for transferring train air conditioning modules, so as to solve the problem that in the prior art, when adjusting the position of the fasteners on the special carrier to match the lifting lugs of the train air conditioning module, it is often necessary to rely on a crane to suspend the module for a long time, which leads to a cumbersome, time-consuming and safety hazard.

[0007] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: A positioning auxiliary device for transferring train air conditioning modules, used to sequentially lift the two lengthwise sides of the train air conditioning module as a whole during the process of placing the train air conditioning module on a special carrier, so that the corresponding bearing fasteners on the special carrier can be smoothly moved to the corresponding lifting lugs on the train air conditioning module. The bearing fasteners on the special carrier are used to fasten the lifting lugs on the train air conditioning module placed thereon. The device is characterized by comprising: The bottom frame is horizontally positioned and has a length extension direction; There are several scissor jacks, all of which are fixedly installed on the base frame and are distributed at intervals along the length of the base frame. Each scissor jack has a base, a top plate, and a transmission mechanism for mechanically driving the top plate to rise and fall under the action of external force. The base is fixedly connected to the bottom frame, the top plate is located directly above the base, and the transmission mechanism is located between the top plate and the base. The transmission mechanism has a horizontal rotating shaft, which is used to rotate under the action of external force to drive the transmission mechanism. The top plate is horizontal, and its top surface forms a support surface for supporting the train's air conditioning module. The length of the base frame extends parallel to the length of the train air conditioning module. The support surfaces of all the scissor jacks together form a support array along the length of the base frame. The support array is used to provide multi-point synchronous support for the train air conditioning module along its length.

[0008] Furthermore, the special vehicle has a telescopic rod structure in its width direction, and all telescopic rod structures are spaced apart along the length direction of the special vehicle. The telescopic rod structure is used to adjust the width of the special vehicle to accommodate the width specification of the train air conditioning module. The number of scissor jacks is adapted to the number of telescopic rod structures, so that there is one scissor jack between every two adjacent telescopic rod structures. The top plate of each scissor jack rises from between the corresponding two adjacent telescopic rod structures to support the bottom of the train's air conditioning module.

[0009] Furthermore, the bottom frame is composed of two strip connecting plates, which are parallel to each other, and each strip connecting plate is provided with several bolt holes evenly distributed along its length. Each side of the base that connects to the strip connecting plate has two through holes, and the spacing between the through holes is the same as the spacing between the bolt holes. The two strip connecting plates are connected to the base of all the scissor jacks by fasteners to form an integrated structure, which facilitates the movement of the whole.

[0010] Furthermore, each pair of adjacent rotating shafts is connected end to end by a transmission rod. At the end of one of the outermost rotating shafts in all the scissor jack arrangement directions, there is a main input shaft for connecting an external rotational power source.

[0011] Furthermore, the transmission rod has a spline-type telescopic structure, which is used to make adaptive telescopic adjustments when increasing or decreasing the number of scissor jacks.

[0012] Furthermore, each rotating shaft has a radial through hole at both ends, and the rotating shaft and the transmission rod are connected by a U-shaped connector. One end of the U-shaped connector is fixed to one end of the transmission rod, and a stud is fixedly connected in the groove of the U-shaped connector. The stud passes through the radial through hole at the end of the corresponding rotating shaft.

[0013] Furthermore, the bottom of the special vehicle is equipped with casters. When the top plate of the scissor jack is fully lowered, the distance between the support surface and the ground is less than the vertical height of the casters, so that the scissor jack can enter from below the special vehicle.

[0014] Furthermore, a hexagonal prism is formed on the main input shaft for use with a wrench or electric drill.

[0015] The beneficial effects of this utility model are: This invention utilizes a series of scissor jacks spaced along the length of the base frame. The top plates of all the scissor jacks together form a support array parallel to the length of the train's air conditioning module. This allows for multi-point synchronous support and overall lifting of the train's air conditioning module's sides. Without relying on large lifting equipment for suspension, this structure provides a stable vertical operating space for aligning the load-bearing fasteners on the special carrier with the module's lifting lugs. This enables operators to smoothly move and adjust the position of the load-bearing fasteners to complete the fastening operation, effectively solving the problems of cumbersome operation and safety hazards caused by the need for crane assistance during the traditional fastener position adjustment process.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This embodiment provides a positioning auxiliary device for transferring train air conditioning modules, aiming to solve the problem in the prior art that, due to the difficulty in adjusting the position of the fasteners on the special carrier 1, it is often necessary to rely on a crane to suspend the air conditioning module for a long time, which leads to cumbersome operation, time-consuming operation and safety hazards.

[0020] For details, see Figures 1 to 7 This positioning auxiliary device includes a base frame 2 and several scissor jacks 3.

[0021] The base frame 2 is set horizontally and has a length extension direction. All scissor jacks 3 are fixedly set on the base frame 2 and are distributed at intervals along the length extension direction of the base frame 2.

[0022] Each scissor jack 3 has a base 3a, a top plate 3c, and a transmission mechanism 3d for mechanically raising and lowering the top plate 3c under external force. The base 3a is fixedly connected to the base frame 2, the top plate 3c is located directly above the base 3a, and the transmission mechanism 3d is located between the top plate 3c and the base 3a.

[0023] The transmission mechanism 3d has a horizontally rotating shaft 3e, which is used to rotate under the action of external force to mechanically drive the top plate 3c to rise and fall. The top plate 3c is horizontal, and its top surface forms a support surface 3g for supporting the train air conditioning module. The length extension direction of the bottom frame 2 is parallel to the length direction of the train air conditioning module. The support surfaces 3g of all the scissor jacks 3 together form a support array in the length extension direction of the bottom frame 2.

[0024] The reason for using array-type lifting instead of single-point lifting is that the box of the train air conditioning module is generally made of sheet metal, and its bottom wall thickness is relatively thin. If only a single jack is used for single-point lifting during the transfer or positioning process, the huge concentrated load can easily cause plastic deformation or even damage to the bottom of the box.

[0025] Therefore, this device forms a support array with scissor jacks 3 distributed along the length direction, which achieves multi-point joint lifting while avoiding the vehicle structure, and evenly distributes the lifting force to multiple areas at the bottom of the module, effectively protecting the structural integrity of the air conditioning module.

[0026] In the above basic scheme, considering that the special vehicle 1 used in conjunction with the train air conditioning module of different width specifications usually has a telescopic rod structure 1a in its width direction, and all telescopic rod structures 1a are spaced apart along the length direction of the special vehicle 1, if the lifting position of the positioning auxiliary device interferes with the telescopic rod of the vehicle, it will cause the vehicle to fail to work properly.

[0027] To address this layout matching issue, the number of scissor jacks 3 in this device is adapted to the number of telescopic rod structures 1a, so that there is one scissor jack 3 between every two adjacent telescopic rod structures 1a.

[0028] During operation, the top plate 3c of each scissor jack 3 rises upwards from between the corresponding two adjacent telescopic rod structures 1a, thereby avoiding the obstruction of the telescopic rods and accurately supporting the bottom of the train's air conditioning module. As a preferred embodiment, in order to further increase the support contact area and reduce the pressure per unit area to prevent the box from deforming, a top rod or strip-shaped top block of a certain length can be added to the top of the top plate 3c of each scissor jack 3. It should be noted that, in order not to interfere with the telescopic rods of the vehicle, the length of the top rod or strip-shaped top block should be designed to be no greater than the distance between two adjacent telescopic rods.

[0029] Furthermore, since the lengths of air conditioning modules of different train models are different, the number of telescopic rods of special carriers 1 of different lengths and sizes will vary. If the position of the scissor jack 3 on the base frame 2 is permanently fixed, it will be difficult to adapt to the changing on-site working conditions. At the same time, in order to facilitate on-site operations, the dispersed jacks need to be transported as a whole.

[0030] Based on this, the base frame 2 is designed to consist of two strip connecting plates 2a, which are parallel to each other. Each strip connecting plate 2a has several bolt holes 2b evenly distributed along its length. Correspondingly, each side of the base 3a connected to the strip connecting plate 2a has two through holes 3b. The spacing between the through holes 3b is the same as the spacing between the bolt holes 2b. Through this design, the two strip connecting plates 2a and the bases 3a of all scissor jacks 3 are connected by fasteners to form an integrated structure.

[0031] This design, which connects all the jacks and the base frame 2 into one unit, is not only convenient for adjusting the spacing, but more importantly, it is for the convenience of moving the whole unit. This is because the adjustable fasteners of the special carrier 1 are set on the side beams in two length directions. When using this device, it usually follows the process of "single-sided operation": first lift up one long side of the air conditioning module, adjust the position of all the fasteners on that side to match the lifting lugs, and then lower the module after the operation on that side is completed. Then, the device needs to be moved to the other long side, and the position of the fastener on the other side needs to be adjusted in the same way. If the jacks are not fixed together, the operator needs to move and realign several jacks one by one, which is extremely time-consuming and laborious.

[0032] The integrated structure allows operators to quickly move the entire row of jacks to the other side in one go, significantly improving work efficiency.

[0033] If all jacks are driven independently, the force exerted by each jack on the bottom of the box (lifting height or speed) will inevitably vary significantly due to human error, resulting in uneven force distribution and causing deformation and damage to the box.

[0034] To solve this problem, each pair of adjacent rotating shafts 3e is connected end to end by a transmission rod 4, thereby connecting all the independent transmission units into a whole. At the end of one of the outermost rotating shafts 3e in all the scissor jacks 3, a main input shaft 5 for connecting an external rotational power source is connected.

[0035] Through this mechanical series connection, only the main input shaft 5 needs to be driven to force all scissor jacks 3 to maintain completely synchronized lifting and lowering movements, ensuring the horizontal posture and uniform force distribution of the air conditioning module during the lifting process.

[0036] Given that the spacing of the scissor jacks 3 is adjustable (by changing the position of the bolt holes 2b) as mentioned in the foregoing embodiments, when the distance between the jacks changes, the rigid transmission rod 4 of fixed length will not be able to connect to the adjacent rotating shaft 3e.

[0037] To address the adaptability of the transmission system to pitch adjustments, the transmission rod 4 is designed as a spline-type telescopic structure. The spline structure allows axial sliding while transmitting torque. Using this telescopic structure, adaptive telescopic adjustments can be made when increasing or decreasing the number of scissor jacks 3 or adjusting their pitch, without the need to replace transmission rods 4 of different lengths, greatly simplifying the adjustment process.

[0038] Furthermore, considering the ease of maintenance and assembly of the equipment, if the rotating shaft 3e and the transmission rod 4 are permanently connected by welding or interference fit, disassembly and assembly will be very difficult once a component is damaged or needs to be rearranged.

[0039] To this end, each rotating shaft 3e has a radial through hole 3f at both ends. The rotating shaft 3e and the transmission rod 4 are connected by a U-shaped connector 6. One end of the U-shaped connector 6 is fixed to one end of the transmission rod 4. A stud 7 is fixedly connected in the groove of the U-shaped connector 6. The stud 7 passes through the radial through hole 3f at the end of the corresponding rotating shaft 3e. This connection method not only ensures the reliable transmission of torque, but also realizes a detachable connection, which greatly facilitates subsequent maintenance and component replacement.

[0040] In addition, as a standalone device, the positioning aid needs to be moved under the dedicated vehicle 1 before the operation begins. Since the bottom of the dedicated vehicle 1 is usually equipped with casters for easy movement, this imposes a limitation on the height of the positioning aid itself.

[0041] If the device is too high in the retracted state, it will not be able to be pushed smoothly into the bottom of the carrier. Therefore, the device has limited the size relationship, that is, when the top plate 3c of the scissor jack 3 is fully lowered, the distance between the support surface 3g and the ground is less than the vertical height of the caster wheel. This design ensures that in the non-working state, the scissor jack 3 can enter from under the special carrier 1 without obstacles, and the lifting operation can be carried out after the position is aligned, thus realizing the efficient deployment of the equipment.

[0042] Finally, to improve the flexibility and efficiency of on-site operation, a hexagonal prism 5g is formed on the main input shaft 5 for use with a wrench or electric drill. This standardized interface design allows operators to use a wrench for fine manual adjustment or an electric drill for rapid electric lifting, thus flexibly choosing the drive method according to actual work needs.

[0043] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered as falling within the scope of protection of this utility model.
