Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the present embodiment provides a railway track oiling device, including an oiling trolley 1, a track roller 3 is installed on the lower surface of the oiling trolley 1, and the track roller 3 is movably connected to the oiling trolley 1. Both sides of the track roller 3 are located on the lower surface of the oiling trolley 1 and a slide groove 101 is opened. The interior of the slide groove 101 is provided with a limiting mechanism 5. The limiting mechanism 5 includes: an outer sleeve 501 and an extension frame 504. The extension frame 504 is movably connected to the outer sleeve 501. The lower end of the extension frame 504 is installed with a clamping roller 505. The holding roller 505 is rotatably connected to the extension frame 504, and a spring 506 is connected between the extension frame 504 and the outer sleeve 501. The spring 506 is fixedly connected to the extension frame 504 and the outer sleeve 501. The upper end of the outer sleeve 501 is located inside the slide groove 101 and a limiting slider 502 is installed. The outer sleeve 501 is slidably connected to the slide groove 101 through the limiting slider 502. A reciprocating screw rod 401 is installed inside the slide groove 101, and one end of the reciprocating screw rod 401 is located outside the oiling trolley 1 and a hand crank 4 is installed.

[0024] like Figure 2-5 As shown, in the present embodiment, an oil filling hole 7 is installed on the upper surface of the oiling trolley 1, and the oil filling hole 7 is arranged through the oiling trolley 1, a push rod 2 is installed on one side end of the oiling trolley 1, and the push rod 2 is fixedly connected to the oiling trolley 1, and an oil injection mechanism 6 is installed on one side of the push rod 2, and an oil injection hole 102 is installed on the lower surface of the oiling trolley 1, and a control valve is installed inside the oil injection hole 102, and an engaging sleeve 503 is arranged on the outer side of the reciprocating screw 401 and inside the limit slider 502, and the engaging sleeve 503 is engaged and movably connected with the reciprocating screw 401.

[0025] The working principle of the utility model is as follows: before use, the limiting mechanism 5 is arranged inside the slide groove 101 away from the two sides of the track roller 3, and after the oiling trolley 1 is placed on the top of the track as a whole, the hand rocker 4 is used to apply torque to control the reciprocating screw 401 to rotate as a whole, so that the meshing sleeve 503 inside the limiting mechanism 5 meshes and rotates as a whole on the outside of the reciprocating screw 401, and after the two limiting mechanisms 5 are controlled to move to the position of the rail as a whole and to the two sides of the track, the extension frame 504 is pulled downward as a whole inside the outer sleeve 501 so that the spring 506 is stretched and deformed, and the clamping roller 505 at the lower end of the extension frame 504 is stretched to a position below the track, Continue to apply torque to the hand joystick 4 to control the clamping rollers 505 at both ends to be clamped on both sides of the track as a whole.
