Description

Technical Field

[0001] This utility model relates to the technical field of railway maintenance, and in particular to a track-mounting device for a two-way turnout grinding robot. Background Technology

[0002] In railway transportation systems, turnouts are critical components, and their condition directly affects the safety and smoothness of train operation. After long-term use, turnout rails are prone to wear, deformation, and other defects, requiring regular grinding and maintenance using grinding robots. Bidirectional turnout grinding robots can efficiently grind turnout rails in different directions; however, their operation faces numerous challenges.

[0003] Traditional fixed tracks are ill-suited to the complex and ever-changing environment of turnout sites, are difficult to adjust after installation, and occupy a significant amount of space during non-operational periods. While some existing movable track devices offer a degree of flexibility, they cannot meet the precise track entry and exit requirements of bidirectional turnout grinding robots under various working conditions. For example, they are difficult to deploy or move in confined spaces, and the insufficient docking precision between the track and the robot poses safety hazards during the robot's entry and exit from the track. Furthermore, the operation is cumbersome, time-consuming, and severely impacts work efficiency. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the present invention provides a track loading and unloading device for a bidirectional turnout grinding robot.

[0005] The technical solution provided by this utility model for a bidirectional turnout grinding robot's on / off track device is as follows:

[0006] A track-mounting device for a two-way turnout grinding robot includes a track frame for transporting the grinding robot and a moving mechanism mounted on the grinding robot. The track frame includes a track rod extending to the rail, and the moving mechanism includes liftable rollers that are supported by the track rods.

[0007] By adopting the above technical solution, the grinding robot can move on and off the track by moving the moving mechanism on the track frame. The vertical lifting of the rollers allows the grinding robot to be placed on or removed from the rail. This track-mounting device effectively solves the problems of poor spatial adaptability, inconvenient operation, and low safety of the current grinding robot in the process of moving on and off the track, and helps to improve the efficiency and quality of grinding operations in the railway turnout area.

[0008] Optionally, the moving mechanism also includes a housing, inside which fixed base one, fixed base two and fixed base three are fixedly connected from top to bottom. A drive rod for use with a wrench is vertically inserted through fixed base one. A lead screw rotatably mounted on fixed base two is connected to the bottom of the drive rod. A lifting rod slidingly inserted on fixed base three is threaded at the bottom of the lead screw. A mounting base is installed at the bottom of the lifting rod, and a roller is installed on the mounting base.

[0009] By adopting the above technical solution, the drive rod can be driven to rotate by a wrench, the drive rod drives the lead screw to rotate, the lead screw is threadedly connected to the lifting rod, and the rotation of the lead screw drives the lifting rod to move up and down, thereby driving the roller to move up and down. The moving mechanism has a reasonable and efficient structure and is easy to operate.

[0010] Optionally, a plug is fixed to the top of the lead screw, and a slot adapted to the plug is opened at the bottom of the drive rod. A spring is installed between the bottom of the drive rod and the second fixed seat, and the spring is sleeved on the lead screw.

[0011] By adopting the above technical solution, it is ensured that the lead screw can be driven to rotate normally only when the roller needs to be adjusted.

[0012] Optionally, the track frame may also include multiple vertically arranged legs, with connecting frames installed between the legs, and the track rods mounted on the connecting frames.

[0013] By adopting the above technical solution, the track frame structure is reasonably designed and easy to assemble and use.

[0014] Optionally, the connecting frame includes a connecting rod that is perpendicular to the support leg, a connecting seat is mounted on the connecting rod, and a track rod is mounted on the connecting seat.

[0015] By adopting the above technical solution, the connecting seat facilitates the positioning and fixing of the track rod.

[0016] Optionally, a hinged seat is installed between two adjacent horizontally connected rods, and a scissor brace is provided between two adjacent longitudinally connected rods. The scissor brace is connected to the hinged seat and the connecting seat respectively.

[0017] By adopting the above technical solution, the track frame can be folded as a whole, making it easy to transport and use.

[0018] Optionally, a slide cylinder is vertically fixed to one end of the connecting rod. The slide cylinder is slidably sleeved on the support leg. Limit holes are provided on both the slide cylinder and the support leg. The slide cylinder is fixed after height adjustment by screws cooperating with the limit holes.

[0019] By adopting the above technical solution, it is easy to adjust the position of the slide on the outrigger according to different terrains, thereby keeping the track rod horizontal and connecting the rail.

[0020] Optionally, at least two sets of track rods are arranged in parallel, and a connecting rod is installed between the ends of the track rods near the rail.

[0021] By adopting the above technical solution, the second connecting rod connects the track rods to form a whole, which improves the overall stability of the track frame. Attached Figure Description

[0029] The following combination Figures 1-6 The present invention will be described in further detail below.

[0030] This utility model discloses an upper and lower track device for a bidirectional turnout grinding robot. (Refer to...) Figure 1 The track-mounting device for the bidirectional turnout grinding robot is used when the grinding robot 1 is mounted on or off the rails. It includes a track frame 2 and a moving mechanism 3. The track frame 2 is detachably placed next to the rails, and the moving mechanism 3 is mounted on the grinding robot 1 and can move the grinding robot 1 along the track frame 2.

[0031] Reference Figures 1-3The track frame 2 includes multiple legs 20 vertically supported on the ground. A connecting frame 21 is provided between four adjacent legs 20. Two sets of track rods 22 are installed on the connecting frame 21. The track rods 22 are perpendicular to the rails. Two adjacent track rods 22 are connected by bolts in the longitudinal direction. A connecting rod 23 is bolted between the ends of the two sets of track rods 22 near the rails. The connecting frame 21 includes a connecting rod 210 perpendicular to the legs 20. Two adjacent connecting rods 210 are connected by a hinge seat 211, and bolts are provided on the hinge seat 211.

[0032] Reference Figures 2-4 A scissor brace 212 is provided between two adjacent longitudinal connecting rods 210. The end of the scissor brace 212 is connected to a hinge seat 211 and a connecting seat 213. The connecting seat 213 is installed on the connecting rod 210, and the track rod 22 is installed on the connecting seat 213. In order to adapt to different ground heights, a slide cylinder 24 is vertically fixed to the end of the connecting rod 210. The slide cylinder 24 is slidably sleeved on the support leg 20. Limit holes are provided on both the support leg 20 and the slide cylinder 24. The height of the slide cylinder 24 is fixed by screws cooperating with the limit holes.

[0033] Reference Figure 1 , Figure 5 and Figure 6 The moving mechanism 3 is installed at the four corners of the polishing robot 1. The moving mechanism 3 includes a housing 30 bolted to the polishing robot 1. Inside the housing 30, from top to bottom, there are three fixed seats: a first fixed seat 300, a second fixed seat 301, and a third fixed seat 302. A drive rod 31 is vertically slidably inserted inside the first fixed seat 300. The top of the drive rod 31 has a groove that cooperates with a wrench.

[0034] Reference Figure 6 A lead screw 32 is rotatably mounted on the second fixed base 301. A prism-shaped insert 33 is fixedly connected to the top of the lead screw 32. A slot adapted to the insert 33 is opened at the bottom of the drive rod 31. A spring 34 is installed between the bottom of the drive rod 31 and the second fixed base 301. The spring 34 is sleeved on the lead screw 32. A quadrangular prism-shaped lifting rod 35 is slidably inserted in the third fixed base 302. The lead screw 32 is threaded into the lifting rod 35. A mounting base 36 is installed at the bottom of the lifting rod 35. A roller 37 is installed in the mounting base 36. The roller 37 is supported by the track rod 22.

[0035] The implementation principle of the bidirectional turnout grinding robot using the track-mounted device in this embodiment is as follows: the track frame 2 can be assembled, disassembled and folded for easy transport and use; the connecting rod 23 is connected to the ends of the two sets of track rods 22, so that the two sets of track rods 22 form a whole to improve stability; by adjusting the height position of the slide cylinder 24 on the support leg 20, the two sets of track rods 22 can be kept horizontal and accurately connected to the track in different terrains.

[0036] The grinding robot 1 moves to the rail on the track frame 2 via the moving mechanism 3. Alternatively, the grinding robot 1 can be manually pushed, with rollers 37 rolling on the track rod 22 to move it. Once the grinding robot 1 is in position, an electric wrench is inserted into the top of the drive rod 31 and pressed down. At this point, the drive rod 31 and the lead screw 32 are connected via a slot and a plug block 33, and the spring 34 is elastically compressed.

[0037] After the electric wrench is turned on, the drive rod 31 rotates and drives the lead screw 32 to rotate. Since the lead screw 32 cannot move up and down and is threadedly connected to the lifting rod 35, the lifting rod 35 is restricted by the fixed seat 302 and can only move upward under the drive of the lead screw 32, thereby causing the roller 37 to rise and disengage from the track rod 22, and the wheel on the grinding robot 1 falls onto the rail. After the electric wrench is removed, the spring 34 elastically extends to drive the drive rod 31 to move upward and disengage from the lead screw 32, so as to ensure that the lead screw 32 can only be rotated normally when needed.

[0038] Then, removing the track frame 2 completes the upper process of the grinding robot 1, and similarly, the lower process of the track robot 1 can be performed. This track-mounting device effectively solves the problems of poor spatial adaptability, inconvenient operation, and low safety in the current process of grinding robot 1 moving up and down the track, helping to improve the efficiency and quality of grinding operations in railway turnout areas.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
