Description

Technical Field

[0001] The utility model relates to the technical field of railway tracks, and more specifically, to an intelligent railway track maintenance robot. Background Art

[0002] Rails are the foundation of railway train operation and crucial to its safety. However, rails laid in the open air are susceptible to erosion by the elements, resulting in uneven heights. High-speed trains running at high speeds on deformed rails are prone to derailment, necessitating regular rail maintenance.

[0003] The traditional rail maintenance process involves manually unscrewing the nut after the location of the rail defect is determined. Multiple workers then insert a crowbar into the bottom of the rail to lift it. Based on the test data, they insert or remove a gasket of the required thickness, tighten the nut, and secure the rail in place, completing the maintenance. Due to the numerous steps involved in the maintenance process, multiple workers are required to collaborate on the construction. The positions of various parts also need to be adjusted when the rail is lifted. Manual construction is slow, and the positions of various parts are prone to offset, affecting the degree of rail fixation. Assembly and transportation are also time-consuming and labor-intensive for workers, slowing down construction and consuming significant labor and time costs. It's difficult to maintain high-quality steel rails at these low points. Utility Model Content

[0004] In order to overcome the deficiencies in the above-mentioned prior art, the utility model provides an intelligent railway track maintenance robot, which can quickly and accurately fix the rails in relative positions to complete maintenance. It has a ranging function and can quickly and accurately reach the location of track defects, providing convenience for rail maintenance work.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A railway track intelligent maintenance robot includes a robot body, a connecting rod, an auxiliary wheel group and a track lifter. The robot body is connected to the auxiliary wheel group via a connecting rod. A load-bearing platform is provided on the robot body. A track lifter control component is provided on the load-bearing platform. The track lifter control component is connected to the track lifter. The track lifter is connected to a pneumatic hydraulic jack. A control panel is provided on the top of the robot body. The control panel is electrically connected to the pneumatic hydraulic jack. A main body positioning wheel is provided at the bottom of the robot body.

[0007] The auxiliary wheel assembly includes an auxiliary wheel housing and an auxiliary positioning wheel. The auxiliary wheel housing is connected to the connecting rod. The auxiliary positioning wheel is arranged in the auxiliary wheel housing. The auxiliary positioning wheel and the main body positioning wheel are arranged at the same height.

[0008] Two floating sleeves are symmetrically arranged at the bottom of the robot body, and the floating sleeves are arranged corresponding to the positions of the track screws. A screw operating handle is arranged on the robot body, and the screw operating handle and the floating sleeves are electrically connected to the control panel.

[0009] The track lifter control assembly includes a first rotating folding arm and a second rotating folding arm, one end of the first rotating folding arm is connected to the top of the load-bearing platform through a first shaft, and the other end of the first rotating folding arm is hinged to the second rotating folding arm through a second shaft, and the track lifter is connected to the end of the second rotating folding arm away from the second shaft.

[0010] A rail lifter guide and limit assembly is provided in the second rotating and folding arm, and the rail lifter is connected to the second rotating and folding arm via the rail lifter guide and limit assembly.

[0011] The track lifter guide and limiting assembly includes a wire rope balancer, a wire rope steering guide wheel and a wire rope. The wire rope balancer and the wire rope steering guide wheel are arranged in the second rotating folding arm. One end of the wire rope is fixed on the wire rope balancer, and the other end is fixedly connected to the top of the track lifter after passing through the wire rope steering guide wheel.

[0012] The rail lifter is provided with a mechanical power-assisting handle.

[0013] The robot body is provided with a main body handle.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This device's robot integrates automatic screw adjustment and rail lifting functions, allowing only two to three people to complete routine maintenance work. The screw locking torque can be set via the control panel, and a floating sleeve automates the tightening and loosening of the screws. Equipped with a custom rail lifter, its operation is controlled by a mechanical power handle, saving time and effort, ensuring safe and reliable maintenance and precise execution. The robot consists of a robot body, rail lifter, connecting rods, and auxiliary wheels. It is easy to maintain and assemble, making it suitable for construction on existing railway lines. The rail lifter control assembly allows the rail lifter to rotate in any direction to position the rail. The rail lifter's guide and limit assembly facilitates control of the rail lifter using the wire rope, allowing it to be retracted to the robot body after use. The auxiliary wheels can also be replaced with the robot body, allowing two robots to operate in parallel, eliminating the need for forward and backward switching and improving operational efficiency. As a key tool for modern railway maintenance, it will provide a strong guarantee for safe railway operations. BRIEF DESCRIPTION OF THE DRAWINGS
