[0031] like Figure 1-5 As shown, the railway freight car coupler height adjustment device provided by the utility model includes a base 1, an adjusting screw 2 and an adjusting rod 3. The base 1 is provided with an adjusting screw 2; an adjusting rod 3 is provided on the outside of the adjusting screw 2, and the adjusting rod 3 is threadedly connected to the adjusting screw 2, and an arc-shaped support plate 4 is provided on the upper end of the adjusting rod 3; limit plates 41 are provided at both ends of the arc-shaped support plate 4, and a fixing groove 42 adapted to the bottom of the railway freight car coupler is provided in the middle of the arc-shaped support plate 4; an adjusting dial 5 is also provided on the outside of the adjusting screw 2, and the adjusting dial 5 is threadedly connected to the adjusting screw 2.
[0032] like Figure 3 As shown, when using the present invention, first, place the base 1 directly below the railway wagon coupler to be adjusted. Then, rotate the adjustment dial 5, which drives the adjustment rod 3 upward along the adjustment screw 2 until the arc-shaped support plate 4 is directly below the railway wagon coupler to be adjusted. Afterwards, fine-tune the position of the base 1 and adjustment rod 3 until the railway wagon coupler to be adjusted is located in the fixed groove 42. Under the action of the base 1 and adjustment rod 3, the arc-shaped support plate 4 lifts the railway wagon coupler to adjust the coupler height. The fixed groove 42 and the limit plate 41 prevent the coupler from sliding, reducing safety hazards and improving safety.
[0033] like Figure 1-2As shown, the base 1 includes a fixed steel plate 11 and fixed legs 12 arranged at the bottom of its four corners. A steel pad 14 is arranged on the fixed steel plate 11, and an adjustment screw 2 is arranged on the steel pad 14. The steel pad 14 can increase the contact area, reduce the pressure during use, and improve the service life.
[0034] like Figure 1-5 As shown, rollers 15 are provided on the fixed legs 12; a fixed horizontal plate 13 is provided between two adjacent fixed legs 12, and a movable handle 6 is provided on the fixed horizontal plate 13, and the movable handle 6 is located between the two rollers 15. When the base 1 is tilted, the rollers 15 come into contact with the ground, and the movable handle 6 is pushed, the movable handle 6 can be used to move the device, which is convenient to use.
[0035] like Figure 1 、 5 As shown, the upper end of the movable handle 6 is provided with a handle 61, and the lower end of the movable handle 6 is provided with a buckle 62 adapted to the fixed horizontal plate 13; the fixed leg 12 is provided with a roller 15. The movable handle 6 has a diameter of 1000 mm and is mounted on the fixed horizontal plate 13 via the buckle 62, which allows the device to be moved and is convenient to use.
[0036] like Figure 1 、 4 As shown, a fixed sleeve 7 is also provided on the outside of the adjusting screw 2; the fixed sleeve 7 is located at the lower end of the adjusting dial 5 and is provided with a locking bolt 71. The fixed sleeve 7 is moved upward along the adjusting screw 2 until it contacts the bottom of the adjusting dial 5. The locking bolt 71 is then tightened to secure the fixed sleeve 5 to the lower end of the adjusting dial 5. This prevents the adjusting dial 5 and the adjusting rod 3 from moving downward due to the weight of the railway wagon coupler, thereby improving safety.
[0037] like Figure 1 、 4 As shown, a locking nut 72 is provided at the front end of the locking bolt 71, and a tightening handle 73 is provided at the rear end of the locking bolt 71.
