[0015] The beneficial effects of the utility model are:

[0016] 1. The oil pipeline welding rail car travel mechanism solves the problem of existing equipment in actual use that the gears in the rail car gear box will produce metal abrasives due to friction during long-term operation through the cooperation between various components.

[0028] refer to Figures 1 to 5 The input end of the transmission shaft 302 passes through the left side of the gear protection box 301 and is fixedly connected to the output end of the drive motor 2. The output end of the transmission shaft 302 passes through the right side of the box body 1 and is fixedly connected to the left side of the travel drive gear 5. The installation cover 403 is fixedly installed on the front side of the gear protection box 301 by bolts. The front end of the spring card 404 is movably connected to the rear end of the strong magnet 402. The surface of the travel drive gear 5 is meshed and connected to the surface of the travel track. A junction box 6 is fixedly installed on the front side of the box body 1, and mounting screw holes 7 are provided at the four corners of the bottom end of the box body 1.

[0029] The above scheme is adopted: through the setting of the torque converter gear 303, the output power of the driving motor 2 can be changed in speed and torque, thereby increasing its torque; through the setting of the spring card 404, the strong magnet 402 can be limited and fixed, thereby avoiding the strong magnet 402 from shifting and shaking during use; through the setting of the mounting screw hole 7, the device can be installed to the specified installation position using the mounting bolts.

[0030] refer to Figures 1 to 5 A ventilation hole 8 is opened on the left side of the box body 1, and the ventilation holes 8 are distributed in an array with equal intervals. An anti-skid pad 9 is fixedly connected to the bottom end of the box body 1, and the material of the anti-skid pad 9 is rubber.

The inner cavity of the magnetic suction box 401 is fixedly connected to a limit block 12, and the surface of the limit block 12 is movably connected to both sides of the strong magnet 402.

[0031] The above scheme is adopted: through the setting of the ventilation hole 8, the inner cavity of the box body 1 can be ventilated, so as to cool the driving motor 2 and avoid the high temperature phenomenon of the driving motor 2 during operation; through the setting of the anti-slip pad 9, the friction at the bottom of the box body 1 can be increased, and the rubber material can absorb and reduce some vibrations; through the setting of the inspection cover 10, the internal components of the box body 1 can be inspected and replaced to avoid the impact of component failure on the operation of the device; through the setting of the bearing body 11, the surface wear of the transmission shaft 302 can be reduced to avoid its breakage during use; through the setting of the limit block 12, the strong magnet 402 can be limited and fixed to avoid its falling off during use.

[0032] Working principle:

[0033] When in use, the components of the device are inspected and replaced through the PLC control panel, and the device is connected to the input power supply through the junction box 6 to provide power for the device. The drive motor 2 is controlled to work to drive the transmission shaft 302 to rotate, and the torque converter gear 303 is rotated by the rotation of the transmission shaft 302. The output end power of the drive motor 2 is changed in speed and torque by the torque converter gear 303, so that its torque is increased, thereby increasing the power, and then the increased power is transmitted to the travel drive gear 5 through the transmission shaft 302 to drive the travel drive gear 5 to rotate. The travel drive gear 5 is meshed and connected with the travel track, so as to drive the device to move on the surface of the travel track. During the operation of the transmission shaft 302 and the torque converter gear 303, wear will occur, thereby generating metal abrasive particles, and the debris will be mixed in the lubricating oil and flow in the inner cavity of the gear protection box 301. When the lubricating oil flows to the surface of the strong magnet 402, the metal abrasive particles in the lubricating oil are adsorbed on the surface of the strong magnet 402 by the strong magnet 402, and no longer flow with the lubricating oil.

[0034] In summary: the oil pipeline welding rail car travel mechanism, through the cooperation between the various components, solves the problem of existing equipment in actual use. During the long-term operation of the gears in the rail car gearbox, metal abrasives will be generated due to friction. The long-term mixing of metal abrasives between the gears will increase the friction between the gears, thereby aggravating the wear between the gears and causing the gearbox to have a short service life.

Ordinary technicians in the relevant technical field can modify or deform the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
