Description

Technical Field

[0001] This invention relates to the field of subway vehicle maintenance technology, and in particular to a tooling for separating the car body and bogie of a subway vehicle. Background Technology

[0002] During the production and maintenance of subway vehicles, it is necessary to separate the car body from the bogie. CN202211241275.5 discloses a tooling for separating the car body and bogie of a subway vehicle. This tooling uses the force at the threaded connection between the collar and the lifting screw to support the center pin, and the separation between the car body and the bogie is achieved by rotating the lifting screw, eliminating the need for a jack and minimizing safety hazards. However, in actual use, during the upward lifting process, the car body and bogie may rise simultaneously. This can make it difficult to separate the car body and bogie, and can also cause the lifting screw to deform due to excessive force. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tooling for separating the car body and bogie of a subway vehicle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tooling for separating the car body and bogie of a subway vehicle includes a sliding seat, two upright plates fixedly connected to the upper side of the sliding seat, a sliding plate slidably connected between the two upright plates, a gantry frame fixedly connected to the upper side of the sliding plate, a motor mounted on the gantry frame, a central shaft fixedly connected to the main shaft of the motor, a screw sleeve detachably connected to the upper end of the central shaft, two sliding grooves provided on the upper side of the gantry frame, a slider slidably connected in each groove, an upright fixedly connected to the upper side of each slider, and a semi-circular rod fixedly connected to one side of each upright. When the two semi-circular rods are aligned, a ring is formed between the two semi-circular rods, and the ring is used to guide the screw sleeve. When the two semi-circular rods are misaligned, the two semi-circular rods support and protect the central shaft to prevent deformation of the central shaft.

[0006] Preferably, the upper end of the central shaft is provided with a hexagonal hole, a hexagonal rod is fixedly connected to the lower side of the screw sleeve, the hexagonal rod is inserted into the hexagonal hole, and a spring is fixedly connected between the bottom of the hexagonal hole and the hexagonal rod.

[0007] Preferably, a lifting device is installed on the upper side of the sliding seat, which is used to drive the slide plate to move up and down.

[0008] Preferably, a base plate is fixedly connected to the upper side of the upright plate, and a pressing device is provided on one side of the base plate. When the central axis is lifted upward, the pressing device generates downward pressure through the linkage component.

[0009] Preferably, the pressing device includes a fixed beam, one end of which is fixedly connected to a hinge seat, a mounting rod is hinged inside the hinge seat, an adjusting screw is threaded onto the mounting rod, and one end of the adjusting screw is fixedly connected to the pressing shaft.

[0010] The beneficial effects of the present invention are as follows: During the upward lifting process of separating the car body and bogie of a subway vehicle, the two semi-circular rods are misaligned with each other, and the two semi-circular rods support and protect the screw sleeve from both sides to prevent the central shaft from deforming during the lifting process; during the upward lifting process, the linkage component causes the pressing device to generate downward pressure on the bogie, thereby facilitating the separation of the car body and the bogie.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] Example 1

[0023] like Figures 1-4As shown, a tooling for separating the car body and bogie of a subway vehicle in this embodiment includes a sliding seat 1, two upright plates 11 are fixedly connected to the upper side of the sliding seat 1, and a sliding plate 13 is slidably connected between the two upright plates 11. A lifting device 12 is installed on the upper side of the sliding seat 1. The lifting device 12 is used to drive the sliding plate 13 to move up and down. The lifting device 12 is the prior art. In this embodiment, the lifting device 12 adopts a hydraulic cylinder.

[0024] The upper side of the skateboard 13 is fixedly connected to the gantry frame 14, the gantry frame 14 is equipped with a motor 15, the main shaft of the motor 15 is fixedly connected to the central shaft 16, the upper end of the central shaft 16 is detachably connected to the screw sleeve 17, the upper end of the central shaft 16 is provided with a hexagonal hole, the lower side of the screw sleeve 17 is fixedly connected to the hexagonal rod 18, the hexagonal rod 18 is inserted into the hexagonal hole, and a spring 19 is fixedly connected between the bottom of the hexagonal hole and the hexagonal rod 18.

[0025] The gantry frame 14 has two sliding grooves on its upper side, and a slider 21 is slidably connected in each groove. Each slider 21 is fixedly connected to a vertical rod 2 on its upper side, and a semi-circular rod 24 is fixedly connected to one side of each vertical rod 2. When the two semi-circular rods 24 are aligned, a ring is formed between the two semi-circular rods 24. The ring is used to guide the screw sleeve 17. When the two semi-circular rods 24 are misaligned, the two semi-circular rods 24 are used to support and protect the central shaft 16 to prevent the central shaft 16 from deforming.

[0026] When using, please refer to Figure 10 The inspection point is located inside the inspection pit 100. The bottom of the inspection pit 100 is equipped with a guide rail 200. The sliding seat 1 in this embodiment can slide back and forth along the guide rail 200. This allows the specific position of the tooling used to separate the subway car body and bogie in this embodiment to be finely adjusted according to the parking position of the subway car. During the separation process, the lifting device pushes the sliding plate 13 upward, causing the screw sleeve 17 to engage with the connecting screw between the subway car body and the bogie. As the sliding plate 13 rises, the screw sleeve 17 moves downward and enters the ring formed by the two semi-circular rods 24. At this point, the sliding plate 13 stops rising, and the motor drives the central shaft 16 to rotate, thereby causing the screw sleeve 17 to rotate and disassemble the connecting screw. When the connecting screw is disassembled, the hexagonal rod 18 moves downward within the hexagonal hole to make room, providing sufficient space to remove the connecting screw. Therefore, the purpose of setting the hexagonal rod 18, the hexagonal hole, and its spring is to make room for the screw sleeve 17, allowing it to enter the ring, guiding and protecting it. Furthermore, it allows the screw sleeve 17 to move downward with the connecting screw, thus removing it.

[0027] After the screws are removed, the screw sleeve 17 and hexagonal rod 18 are removed. A lifting screw is inserted into the hexagonal hole, and the sliding plate 13 is raised using the lifting device. This, in turn, lifts the center pin between the subway car body and the bogie, thus separating the subway car body from the bogie. During the upward lifting process, the two semi-circular rods 24 are misaligned, providing support and protection for the screw sleeve 17 from both sides, preventing deformation of the center shaft 16 during the lifting process.

[0028] Simultaneously, during the lifting process, to prevent the car body and bogie from rising simultaneously, a base plate 31 is fixedly connected to the upper side of the upright plate 11. A pressing device 4 is provided on one side of the base plate 31. When the central shaft 16 is lifted upward, the pressing device 4 generates downward pressure through a linkage assembly. The pressing device 4 includes a fixed beam 41, one end of which is fixedly connected to a hinge seat 42. A mounting rod 43 is hinged inside the hinge seat 42, and an adjusting screw 44 is threaded onto the mounting rod 43. One end of the adjusting screw 44 is fixedly connected to a pressing shaft 45. Thus, during the upward lifting process, the pressing device 4 generates downward pressure on the bogie through the linkage assembly, thereby facilitating the separation of the car body and the bogie.

[0029] Example 2

[0030] See Figure 7 and Figure 8 and combined Figures 1-3 Based on Embodiment 1, the linkage component includes a base plate 31 fixed on the upright plate 11. The base plate 31 is vertically arranged, and a first vertical groove and a second vertical groove are provided on one side of the base plate 31. The first vertical groove and the second vertical groove are located on the same side of the base plate 31. A first vertical slide rod is slidably connected in the first vertical groove, and a first rack 32 is fixedly connected to one side of the first vertical slide rod. A second vertical groove is slidably connected in the second vertical groove, and a second vertical slide rod is slidably connected in the second vertical groove. A second rack 34 is fixedly connected to one side of the second vertical slide rod. The fixing beam 41 of the pressing device 4 is fixed to the second vertical slide rod. A gear 33 is rotatably connected to one side of the base plate 31, and both the first rack 32 and the second rack 34 mesh with the gear 33. At the same time, an insertion tube 35 is fixedly connected to one side of the first vertical slide rod, and an insertion rod 23 is fixedly connected to one side of the upright rod 2. The insertion rod 23 and the insertion tube 35 can be inserted and engaged. Before lifting, the upright 2 moves horizontally, allowing the insert rod 23 to be inserted into the insert tube 35. During the lifting process, the first vertical slide rod and the first rack 32 rise, and under the action of the gear 33, the second vertical slide rod and the second rack 34 descend, and the pressing device 4 descends, thereby causing the pressing shaft 45 to exert downward pressure on the bogie. At the same time, when providing downward pressure to the bogie, the bogie's suspension system deforms. A rangefinder is installed on the top of the base plate 31 (not shown in the figure). The rangefinder monitors the deformation on both sides of the bogie. If the deformation on both sides is inconsistent, further inspection of the suspension system on both sides is required.

[0031] Example 3

[0032] See Figure 5 and Figure 6 and combined Figures 1-3 Based on Embodiment 1, the linkage component includes a base plate 31 fixed on the upright plate 11. The base plate 31 is vertically arranged, and a first vertical groove and a second vertical groove are provided on one side of the base plate 31. The first vertical groove and the second vertical groove are respectively located on both sides of the base plate 31. A first vertical slide rod is slidably connected in the first vertical groove, and a first rack 32 is fixedly connected to one side of the first vertical slide rod. A second vertical groove is slidably connected in the second vertical groove, and a second vertical slide rod is slidably connected in the second vertical groove. A second rack 34 is fixedly connected to one side of the second vertical slide rod. The fixing beam 41 of the pressing device 4 is fixed to the second vertical slide rod. A gear 33 is rotatably connected to one side of the base plate 31, and the first rack 32 meshes with the gear 33. An intermittent gear 36 is coaxially fixedly connected to the other end of the gear 33, and the teeth of the intermittent gear 36 mesh with the second rack 34. At the same time, an insertion tube 35 is fixedly connected to one side of the first vertical slide rod, and an insertion rod 23 is fixedly connected to one side of the upright rod 2. The insertion rod 23 and the insertion tube 35 can be inserted and engaged. Before lifting, the upright 2 moves horizontally, allowing the insert 23 to be inserted into the insert tube 35. During the lifting process, the first vertical slide bar and the first rack 32 rise. The rise of the first rack 32 causes the gear 33 to engage with the intermittent gear 36, resulting in the intermittent descent of the second vertical slide bar and the second rack 34. The pressing device 4 also descends intermittently, causing the pressing shaft 45 to exert downward pressure on the bogie multiple times. Simultaneously, the multiple downward pressures on the bogie cause deformation of the bogie's suspension system. A rangefinder (not shown in the figure) is mounted on the top of the base plate 31. The rangefinder monitors the deformation on both sides of the bogie. If the deformation on both sides is inconsistent, further inspection of the suspension system on both sides is required. Compared to embodiment 2, this embodiment can provide multiple downward pressures on the bogie, better aligning the car body and bogie, and causing multiple deformations of the suspension system. The rangefinder can also monitor the deformation on both sides of the bogie multiple times, resulting in more accurate monitoring.
