Description

Technical Field

[0001] This invention belongs to the field of rail vehicle technology, specifically relating to a rail vehicle with an undercarriage mounting bracket featuring an added or modified positioning structure and its installation method. Background Technology

[0002] When rail vehicles are lifted and transported, they are generally lifted by connecting a lifting rope to a lifting device fixed on the rail vehicle body. However, most common lifting devices are fixed to the rail vehicle body, which makes them unadjustable. Alternatively, one type of lifting device may be matched to one type of rail vehicle, resulting in poor applicability. Furthermore, some lifting devices consist of two sets of crossbeams located under the rail vehicle body, with both ends of the lifting device extending to the sides of the rail vehicle body. However, the connection points between the two sets of crossbeams and the rail vehicle body cannot be adjusted according to the width of the bottom of the rail vehicle body, or the position of the connection point cannot be quickly fixed after adjustment, causing inconvenience in use. To address these issues, we propose a rail vehicle with an undercarriage lifting seat featuring an added positioning structure and its installation method. Summary of the Invention

[0003] The purpose of this invention is to provide a rail vehicle with an undercarriage suspension seat featuring an added or modified positioning structure and its installation method, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a rail vehicle with an undercarriage suspension seat with an added or modified positioning structure, comprising two sets of horizontally arranged transverse seats at the front and rear, the two sets of transverse seats being fixedly connected by an adjusting positioning mechanism, the adjusting positioning mechanism being used to adjust the distance between the two sets of transverse seats and then fix the two sets of transverse seats.

[0005] The sliding cavity inside the transverse seat has telescopic plates slidingly connected to the left and right ends, and gears are connected between the two sets of telescopic plates. When one set of telescopic plates moves, the gears rotate, thereby causing the two sets of telescopic plates to move towards or away from each other.

[0006] The inner end of the telescopic plate extends out of the groove at the top of the transverse seat and is connected to a support seat. The support seat is used to be locked on the bottom side of the rail vehicle. The outer end of the telescopic plate is fixed with a lifting head, and the lifting head is provided with a lifting ring for tying the lifting rope.

[0007] The top of the transverse seat is provided with a positioning locking mechanism, which is used to lock the gear and fix the length of the outer end of the telescopic plate extending out of the transverse seat, thereby realizing the adjustment of the distance between the left and right sets of support seats on the same set of transverse seats.

[0008] This invention also provides an installation method for a rail vehicle with an undercarriage mounting bracket featuring an added or modified positioning structure, specifically including the following steps:

[0009] S1. First, measure the distance between the bottom of the side of the rail vehicle. After inserting the top of the elastic plate into the slot on the side of the vertical plate, the second spring is in a compressed state, which fixes the U-shaped moving seat. The two ends of the U-shaped moving seat do not contact the gear.

[0010] Then, pull the telescopic plate outward or push it inward according to the distance, thereby adjusting the distance between the left and right sets of support seats on the same set of transverse seats, so that the subsequent support seat is locked at the bottom side of the rail vehicle.

[0011] S2. Pull the top of the elastic plate out of the slot on the side of the vertical plate. At this time, under the action of the second spring, the U-shaped moving seat moves towards the gear until both ends of the U-shaped moving seat are locked in the gear tooth groove, locking the gear and fixing the telescopic plate, so that the distance between the left and right sets of support seats can be adjusted and fixed.

[0012] S3. The bottom of the lifting rope is tied to the lifting ring on the lifting head to lift the two sets of transverse seats so that the transverse seats are located below the rail vehicle.

[0013] By moving the movable block closer to the horizontal seat using the toggle plate, the first spring is in a compressed state.

[0014] Then rotate one end of the positioning plate around the first pin until the other end of the positioning plate moves into the first U-shaped groove, while the snap-fit ​​pin is snapped into the corresponding inclined groove.

[0015] Then release the toggle plate. At this time, under the elastic force of the first spring, the moving block moves towards the locking post until the locking post is engaged in the C-shaped positioning groove, thus completing the fixing between the two sets of transverse seats.

[0016] S4. Finally, lift the hoisting rope so that after the transverse seat is lifted, the support seat is locked at the bottom side of the rail vehicle, and the rail vehicle can be lifted and transported.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a rail vehicle with an undercarriage suspension seat with an added and modified positioning structure and its installation method. When a set of telescopic plates moves, the gear rotates, thereby causing the two sets of telescopic plates to move towards or away from each other. By pulling the telescopic plates outward or pushing them inward, the distance between the left and right sets of support seats on the same set of transverse seats can be adjusted. This adjustment method is simple and quick.

[0018] Pull the top of the elastic plate out of the slot on the side of the vertical plate. At this time, under the action of the second spring, the U-shaped moving seat moves towards the gear until both ends of the U-shaped moving seat are locked in the gear tooth groove, locking the gear. In this way, the locking and fixing of the telescopic plate position can be completed simply and quickly through the setting of the positioning locking mechanism, so that the distance between the left and right sets of support seats can be adjusted and fixed.

[0019] Furthermore, after adjusting the distance between the left and right sets of support seats on the same set of transverse seats, the support seats are locked at the bottom side of the rail vehicle after the transverse seats are lifted, which can meet the lifting and transportation of rail vehicles of different sizes.

[0020] Rotate one end of the positioning plate around the first pin until the other end of the positioning plate moves into the first U-shaped groove seat, and at the same time, make the locking pin engage into the corresponding inclined groove. After the locking pin is engaged into the inclined groove at different positions, the distance between the front and rear sets of transverse seats can be adjusted. After the front and rear sets of transverse seats are lifted, they can provide stable support for the front and rear of the rail vehicle, and prevent the rail vehicle from becoming unstable when lifted because the front and rear sets of transverse seats are located in the middle of the bottom of the rail vehicle and the distance between the front and rear sets of transverse seats is too close.

[0021] Release the toggle plate. At this time, under the elastic force of the first spring, the moving block moves towards the locking post until the locking post is engaged in the C-shaped positioning groove. This completes the fixing between the two sets of transverse seats. By adjusting the setting of the positioning mechanism, the fixed connection between the two sets of transverse seats can be achieved simply and quickly, which is convenient to use.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-6 A rail vehicle with an undercarriage mounting bracket with an added and modified positioning structure includes two sets of horizontally arranged transverse seats 1 at the front and rear. The two sets of transverse seats 1 are fixedly connected by an adjustment positioning mechanism. The adjustment positioning mechanism is used to adjust the distance between the two sets of transverse seats 1 and then fix the two sets of transverse seats 1.

[0031] The sliding cavity 2 inside the transverse seat 1 has telescopic plates 5 slidingly connected to the left and right ends, and a gear 18 is connected between the two sets of telescopic plates 5. When one set of telescopic plates 5 moves, the gear 18 rotates, thereby causing the two sets of telescopic plates 5 to move towards each other or away from each other.

[0032] The inner end of the telescopic plate 5 extends out of the groove 3 at the top of the transverse seat 1 and is connected to a support seat 6. The support seat 6 is used to be locked on the bottom side of the rail vehicle 17. The outer end of the telescopic plate 5 is fixed with a lifting head 8, and the lifting head 8 is provided with a lifting ring 7 for tying the lifting rope.

[0033] The top center of the transverse seat 1 is provided with a positioning locking mechanism 10, which is used to lock the gear 18 and fix the length of the outer end of the telescopic plate 5 extending out of the transverse seat 1, thereby realizing the adjustment of the distance between the left and right sets of support seats 6 on the same set of transverse seats 1.

[0034] The inner sidewalls of the two sets of transverse seats 1 are respectively fixed with a first U-shaped groove seat 14 and a second U-shaped groove seat 16. The adjustment and positioning mechanism includes a positioning plate 4 connected between the first U-shaped groove seat 14 and the second U-shaped groove seat 16, and a positioning mechanism that positions the connection between the first U-shaped groove seat 14 and the positioning plate 4.

[0035] The rear end of the positioning plate 4 is connected to the second U-shaped groove seat 16 through the first pin 15. The front end of the positioning plate 4 is provided with a snap-fit ​​post 13. The first U-shaped groove seat 14 is provided with several sets of inclined grooves 141. After the snap-fit ​​post 13 is snapped into the corresponding inclined groove 141, the positioning mechanism prevents the snap-fit ​​post 13 from slipping out through the inclined groove 141.

[0036] The positioning mechanism includes a first spring 12 at the front end of the first U-shaped groove seat 14 and a positioning head 11 connected to the front end of the first spring 12. The positioning head 11 includes a moving block 111 that slides inside the first U-shaped groove seat 14, a C-shaped positioning groove 112 connected to the rear end of the moving block 111, and a toggle plate 113 connected to the right side of the moving block 111. The toggle plate 113 extends out through a rectangular slot on the right side of the first U-shaped groove seat 14.

[0037] Under the elastic force of the first spring 12, the moving block 111 moves backward along the inside of the first U-shaped groove seat 14 until the locking post 13 is engaged in the C-shaped positioning groove 112.

[0038] Both the inner sides of the left and right telescopic plates 5 are provided with racks 9, and the gears 18 mesh with the racks 9.

[0039] The positioning locking mechanism 10 includes a mounting base 102 fixed to the top of the transverse seat 1 by bolts 107, an L-shaped bracket 101 connected to the side of the mounting base 102, and a U-shaped movable seat 105 movably connected inside the L-shaped bracket 101.

[0040] The gear 18 inside the transverse seat 1 is movably connected to the lower middle part of the mounting seat 102 via the second pin 106;

[0041] The bottom of the L-shaped bracket 101 extends into the transverse seat 1 via the sliding groove 3. The pin 103 through the middle of the U-shaped movable seat 105 is sleeved with the second spring 104 and then screwed to the bottom of the L-shaped bracket 101. Under the elastic force of the second spring 104, the U-shaped movable seat 105 moves towards the gear 18 until both ends of the U-shaped movable seat 105 are stuck in the tooth grooves of the gear 18, thus locking the gear 18.

[0042] The vertical plate 1051 at the top of the U-shaped movable seat 105 extends through the rectangular through groove 1011 at the horizontal part of the L-shaped bracket 101, and the rectangular through groove 1011 is also provided with an elastic plate 1012. After the top of the elastic plate 1012 is inserted into the slot on the side of the vertical plate 1051, the U-shaped movable seat 105 is fixed. At this time, the two ends of the U-shaped movable seat 105 do not contact the gear 18.

[0043] This invention also provides an installation method for a rail vehicle with an undercarriage mounting bracket featuring an added or modified positioning structure, specifically including the following steps:

[0044] S1. First, measure the distance between the bottom of the side of the rail vehicle 17. After inserting the top of the elastic plate 1012 into the slot on the side of the vertical plate 1051, the second spring 104 is in a compressed state, which fixes the U-shaped moving seat 105. The two ends of the U-shaped moving seat 105 do not contact the gear 18.

[0045] Then, pull the telescopic plate 5 outward or push it inward according to the distance, so as to adjust the distance between the left and right sets of support seats 6 on the same set of transverse seats 1, so that the subsequent support seat 6 is locked at the bottom side of the rail vehicle 17.

[0046] S2. Pull the top of the elastic plate 1012 out of the slot on the side of the vertical plate 1051. At this time, under the action of the second spring 104, the U-shaped moving seat 105 moves towards the gear 18 until both ends of the U-shaped moving seat 105 are stuck in the tooth groove of the gear 18, locking the gear 18 and fixing the telescopic plate 5, so that the distance between the left and right sets of support seats 6 can be adjusted and fixed.

[0047] S3. The bottom of the lifting rope is tied to the lifting ring 7 on the lifting head 8 to lift the two sets of transverse seats 1, so that the transverse seats 1 are located below the rail vehicle 17.

[0048] By moving the movable block 111 closer to the transverse seat 1 using the toggle plate 113, the first spring 12 is in a compressed state.

[0049] Then, one end of the positioning plate 4 is rotated around the first pin 15 until the other end of the positioning plate 4 moves into the first U-shaped groove 14, while the snap-fit ​​post 13 is snapped into the corresponding inclined groove 141.

[0050] Then release the toggle plate 113. At this time, under the elastic force of the first spring 12, the moving block 111 moves towards the locking post 13 until the locking post 13 is locked into the C-shaped positioning groove 112, thus completing the fixing between the two sets of transverse seats 1.

[0051] S4. Finally, lift the hoisting rope so that after the horizontal seat 1 is lifted, the support seat 6 is locked at the bottom side of the rail vehicle 17, and the rail vehicle 17 can be lifted and transported.

[0052] In summary, compared with the prior art, when one set of telescopic plates 5 moves, the gear 18 rotates, thereby causing the two sets of telescopic plates 5 to move towards or away from each other. By pulling the telescopic plates 5 outward or pushing them inward, the distance between the left and right sets of support seats 6 on the same set of transverse seats 1 can be adjusted. This adjustment method is simple and quick.

[0053] Pull the top of the elastic plate 1012 out of the slot on the side of the vertical plate 1051. At this time, under the action of the second spring 104, the U-shaped moving seat 105 moves towards the gear 18 until both ends of the U-shaped moving seat 105 are locked in the tooth groove of the gear 18, locking the gear 18. In this way, the locking and fixing of the position of the telescopic plate 5 can be completed simply and quickly through the setting of the positioning locking mechanism 10, so that the distance between the two sets of support seats 6 can be adjusted and fixed.

[0054] Furthermore, after the distance between the two sets of support seats 6 on the same set of transverse seats 1 is adjusted, the support seats 6 are locked at the bottom side of the rail vehicle 17 after the transverse seat 1 is lifted, which can meet the lifting and transfer of rail vehicles 17 of different sizes.

[0055] Rotate one end of the positioning plate 4 around the first pin 15 until the other end of the positioning plate 4 moves into the first U-shaped groove seat 14, and at the same time, make the locking pin 13 engage into the corresponding inclined groove 141. After the locking pin 13 is engaged into the inclined groove 141 at different positions, the distance between the front and rear sets of transverse seats 1 can be adjusted. After the front and rear sets of transverse seats 1 are lifted, they can provide stable support for the front and rear parts of the rail vehicle 17, and prevent the rail vehicle 17 from being unstable when lifted because the front and rear sets of transverse seats 1 are located in the middle of the bottom of the rail vehicle 17 and the distance between the front and rear sets of transverse seats 1 is too close.

[0056] Release the toggle plate 113. At this time, under the elastic force of the first spring 12, the moving block 111 moves towards the locking post 13 until the locking post 13 is engaged in the C-shaped positioning groove 112. This completes the fixing between the two sets of transverse seats 1. By adjusting the setting of the positioning mechanism, the fixed connection between the two sets of transverse seats 1 can be achieved simply and quickly, which is convenient to use.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
