Description

Technical Field

[0001] This utility model relates to the field of railway maintenance equipment technology, specifically a railway track maintenance device. Background Technology

[0002] Railway maintenance mainly includes two aspects: railway line maintenance and railway structure maintenance. Railway line maintenance involves the repair and upkeep of the roadbed and tracks, while railway structure maintenance involves the upkeep and upkeep of railway bridges, tunnels, and buildings.

[0003] Existing railway track maintenance equipment has low integration and cannot perform simultaneous maintenance on rails and sleeper foundations. Tracks are inconvenient to maintain multiple times, the equipment is prone to tipping over during track maintenance, and the equipment is inconvenient to move after maintenance, resulting in low maintenance efficiency. Therefore, we propose a railway track maintenance device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a railway track maintenance device. This device can not only maintain the sleeper foundation and prevent the foundation settlement from affecting the normal use of the track, but also grind the surface of the rail. The track has strong stability during use, which can prevent the maintenance device from falling or derailing. At the same time, the maintenance device is easy to move, thereby improving the maintenance efficiency and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a railway track maintenance device, comprising a base plate, steel wheels fixedly connected to the four corners of the lower surface of the base plate, and a drive shaft fixedly connected between the front steel wheels, a motor fixedly connected to the front right side of the upper surface of the base plate, the output shaft of the motor being connected to the drive shaft via a synchronous belt, mounting grooves being provided on the left and right sides of the middle of the upper surface of the base plate, an electric cylinder being fixedly connected inside the mounting groove, a fixing plate being fixedly connected to the telescopic end of the electric cylinder, shock-absorbing blocks being fixedly connected to both ends of the lower surface of the fixing plate, and a vibration pump being fixedly connected to the lower end of the shock-absorbing blocks, a battery being fixedly connected to the front left side of the upper surface of the base plate, a wireless signal control module being fixedly connected to the middle right side of the upper surface of the base plate, and connecting frames being fixedly connected to the left and right sides of the rear side of the base plate, with a contour grinding mechanism fixedly connected to the lower end of the connecting frames;

[0006] Wherein: the input terminal of the wireless signal control module is electrically connected to the output terminal of the battery, and the output terminal of the wireless signal control module is electrically connected to the input terminals of the electric cylinder, the vibration pump, the motor and the discharge valve respectively.

[0007] Furthermore, it also includes a protective cover, which is fixedly connected to the front end of the upper surface of the base plate.

The front surface of the protective cover has an inspection port, and a sealing plate is hinged to the inspection port. The installed protective cover can protect the battery, wireless signal control module and motor, prevent debris from splashing and damaging the equipment and affecting its normal use, thereby making the equipment safer during use.

[0008] Furthermore, it also includes a steel grit hopper and a discharge valve. The steel grit hopper is fixedly connected to the rear side of the upper surface of the base plate. Discharge valves are fixedly connected to the left and right sides of the rear side of the steel grit hopper, and the inlet end of the discharge valve is connected to the outlet of the steel grit hopper. The discharge valve is an electric ball valve, and the input end of the discharge valve is electrically connected to the output end of the wireless signal control module.
