Its design typically has high shear strength and can cope with impact loads under complex working conditions.

[0003] In the existing technology, the lifting bolt removal and installation equipment with strong shear resistance used in train maintenance is usually installed on a mobile base. This design is mainly to meet the needs of flexible movement and stable support of the equipment during maintenance operations.

However, the wheel structure has limited adaptability to gravel roads, and jamming may occur under complex working conditions on train tracks, ultimately affecting the overall work efficiency. Therefore, a shear-resistant lifting bolt removal and installation equipment for train maintenance is proposed to address the above problems. Utility Model Content

During the movement of the track wheel along the track, it can drive the connecting tooth column to rotate. The connecting tooth column drives the rotating rod to rotate through the transmission gear and transmission belt, thereby driving the lifting belt to rotate upward. The rotating lifting belt can also move protruding stones. Finally, the stones are moved upward by the lifting belt and enter the storage area on the side wall of the mobile base.

[0018] Specific implementation examples are given below.

[0019] like Figure 1-4As shown, a high-shear-strength lifting bolt assembly / disassembly device for train maintenance includes a movable base 1; a connecting disc 11 is rotatably connected to the inner bottom of the movable base 1; a pair of track wheels 12 are rotatably connected to both side walls of the movable base 1; multiple sets of extrusion plates 13 are slidably connected to the inner side of the track wheels 12; elastic connecting plates 14 are fixedly connected to the side walls of the multiple sets of extrusion plates 13; the elastic connecting plates 14 are interconnected with the inner side walls of the track wheels 12; an extrusion column 15 is slidably connected to the inner side of the track wheels 12; a threaded column 16 is rotatably connected to the end of the extrusion column 15; a limiting rod 17 is sleeved on the inner side of the threaded column 16; the limiting rod 17 is interconnected with the side wall of the movable base 1; a threaded rotating column 110 is rotatably connected to the side wall of the track wheel 12 near the limiting rod 17; a rotating bevel gear column 18 is rotatably connected to both side walls of the movable base 1; the end of the bevel gear column 18 meshes with the side wall of the threaded rotating column 110; a transmission belt is rotatably connected to the outer side walls of the pair of bevel gear columns 18. 19; The inner wall of the transmission belt 19 is rotatably connected to the outer wall of the connecting disc 11; During operation, the operator can move on the track-driven mobile base 1 via multiple pairs of track wheels 12. When it is necessary to push the mobile base 1 to move on the gravel road within the track, the connecting disc 11 can be directly rotated, causing the transmission belt 19 to drive a pair of bevel gear columns 18 to rotate. Because the bevel gear columns 18 and the threaded rotating column 110 mesh with each other, and the movement range of the threaded column 16 is limited by the limiting rod 17, the threaded column 16 can only move horizontally inside the track wheel 12. During the movement of the threaded column 16, multiple sets of extrusion plates 13 can be pushed outward by the extrusion column 15. At this time, the curved plates on the outer walls of the multiple sets of extrusion plates 13 cooperate with each other to directly support the track wheel 12 and rotate instead of the track wheel 12. The overall device can reduce the possibility of jamming in complex working conditions of train tracks due to the limited adaptability of the wheel structure to gravel roads, thereby improving the overall work efficiency.

The sidewalls are rotatably connected. During operation, as the track wheel 12 moves along the track, it drives the connecting toothed column 2 to rotate. The connecting toothed column 2, through the transmission gear 21 and the transmission belt 22, drives the rotating rod 23 to rotate, thereby driving the lifting belt 24 to rotate upward. The rotating lifting belt 24 can move the protruding stones, and finally the stones move upward through the lifting belt 24 and enter the storage area on the sidewall of the mobile base 1. The overall device improves the flatness of the stone path in the track and reduces the risk of the protruding stones on the stone path scratching the chassis of the mobile base 1.

[0021] Furthermore, such as Figure 1 As shown, fixed seats 3 are fixedly connected to both sides of the movable base 1; a sealing plate 31 is fixedly connected to the bottom of the fixed seat 3; the sealing plate 31 is located above the bevel gear column 18; during operation, the fixed seat 3 and the sealing plate 31 cooperate with each other to block external impurities, thereby reducing the occurrence of external impurities directly adhering to the meshing point between the bevel gear column 18 and the threaded rotating column 110; the overall device improves the stability when the bevel gear column 18 drives the threaded rotating column 110 to rotate.

[0023] Furthermore, such as Figure 1 As shown, a pair of connecting columns 5 are fixedly connected to one side of the movable base 1; an operating column 51 is fixedly connected between the top ends of the pair of connecting columns 5; during operation, the connecting columns 5 and the operating column 51 cooperate with each other, and the operator can move the movable base 1 through the operating column 51, thereby improving the stability of the movable base 1 when it moves.

[0024] Furthermore, such as Figure 1 As shown, the side wall of the enclosure plate 31 is provided with an observation window 6; during operation, the staff can directly observe the inside of the enclosure plate 31 through the observation window 6, thereby improving the ease of changing the size of the track wheel 12.

[0025] Furthermore, such as Figure 3 As shown, a protective layer 7 is fixed to the outer wall of the lifting belt 24. During operation, the protective layer 7 itself is made of wear-resistant material, and the overall device reduces the situation where the lifting belt 24 is subjected to long-term friction with the stones, which could lead to severe wear.

[0026] Working principle: During operation, the operator can move the movable base 1 on the track driven by multiple pairs of track wheels 12.

Because the bevel gear columns 18 and the threaded rotating column 110 mesh with each other, and the movement range of the threaded column 16 is limited by the limiting rod 17, the threaded column 16 can only move horizontally inside the track wheels 12. During the movement of the threaded column 16, multiple sets of extrusion plates 13 can be pushed outward by the extrusion column 15; at this time, multiple The curved plates on the outer side of the extrusion plate 13 cooperate with each other to directly support the track wheel 12 and replace the track wheel 12 in rotation. The overall device can reduce the possibility of jamming in complex working conditions of train tracks due to the limited adaptability of the wheel structure to gravel roads, thereby improving the overall work efficiency. During the movement of the track wheel 12 along the track, it can drive the connecting toothed column 2 to rotate. The connecting toothed column 2, through the transmission gear 21 and the transmission belt 22, drives the rotating rod 23 to rotate, thereby driving the lifting belt 24 to rotate upward. The rotating lifting belt 24 can also move protruding stones. Finally, the stones move upward via the lifting belt 24 and enter the storage area on the side wall of the moving base 1. The overall device improves the flatness of the stone path within the track; the overall device reduces the risk of protruding stones on the stone path scraping the chassis of the moving base 1; the fixed seat 3 and the sealing plate 31 cooperate to block external impurities, thereby reducing the occurrence of external impurities directly adhering to the meshing point of the conical tooth column 18 and the threaded rotating column 110; the overall device improves the stability when the conical tooth column 18 drives the threaded rotating column 110 to rotate; the fixed plate 4 and the fixed ring 41 cooperate to support the middle part of the connecting plate 11. The support structure reduces the load at the connection between the connecting plate 11 and the movable base 1, thus improving the stability of the connecting plate 11 during long-term operation. The connecting column 5 and the operating column 51 work together, allowing the operator to move the movable base 1 via the operating column 51, thereby improving the stability of the movable base 1 during movement. The operator can directly observe the inside of the closed plate 31 through the observation window 6, thus improving the ease of changing the size of the track wheel 12. The protective layer 7 is made of wear-resistant material, reducing the risk of severe wear caused by prolonged friction between the lifting belt 24 and the stones.
