[0028] See also Figure 1 , Figure 2 and Figure 3 , showing the improved two-way anti-slip wheel stopper of the utility model.

[0029] like Figure 1 As shown, the improved two-way anti-skid wheel stopper of the utility model includes a wheel stopper base 10, a wheel stop block 20 and a handle 30. The wheel stop block 20 is detachably fixed to the wheel stopper base 10 by a plurality of fastening bolts 40, and the handle 30 is fixed to the wheel stopper base 10 by fixing bolts 50.

[0030] Also see Figure 2The wheel stopper base 10 includes a base plate 11, a front wing 13, a rear wing 12 and a support handle 15 which are welded and fixed together. The base plate 11 is located at the bottom to be set on the rail, the front wing 13 and the rear wing 12 are symmetrically structured and are respectively welded and fixed to the two sides of the base plate 11, and the support handle 15 is welded and fixed to the outer side of the front wing 13 to fix the handle. The front wing 13 and the rear wing 12 are correspondingly formed with a plurality of through holes 14 for fastening bolts 40 to pass through. The wheel stopper 20 is located between the front wing 13 and the rear wing 12 and is provided with a plurality of fixing holes for fastening bolts 40 to pass through and fix. Therefore, the plurality of fastening bolts 40 pass through the front wing 13, the wheel stopper 20 and the rear wing 12 in turn and are fixed. The two ends of the wheel stopper 20 are symmetrically structured and are respectively formed with stopping arc surfaces, thereby realizing the bilateral use function without turning the direction of the wheel stopper.

[0031] The base plate 11 is formed by bending a 2-3 mm thick steel plate, which is bent downward at an angle of 165-175°, and the bending radius is R50-R100, so that a shape close to the rail head is formed on the lower surface of the base plate 11, achieving better contact and stable support.

[0032] Among them, the through holes on the front wing 13 are 4 circular through holes, and the through holes on the rear wing 12 are 4 square through holes. The fastening bolt is a semicircular head square neck bolt. The circular through hole is for the thread of the semicircular head square neck bolt to pass through, and the square through hole matches the square neck of the semicircular head square neck bolt to effectively prevent the bolt from rotating when the fastening nut is tightened, providing better operating performance, making it more convenient and quick for operating and maintenance personnel to disassemble and fix, and preventing movement.

[0033] The support handle 15 is made of round steel, one end of which is welded to the outer side surface of the front wing 13 at an angle of 60-65 degrees, and the other end is provided with a through hole for assembling the handle.

[0034] like Figure 3 As shown, the handle 30 is composed of a handle rod 31 and a grip 32. One end of the handle rod 31 forms a mounting hole 34 corresponding to the through hole on the support handle 15, so that the fixing bolt 50 passes through the through hole of the support handle 15 and the mounting hole 34 of the handle rod 31 in sequence to fix the handle to the wheel stopper base 10. The handle rod 31 and the grip 32 are both made of round tubes. The grip 32 is vertically welded to the other end of the handle rod 31. Both ends of the handle 32 are sealed by handle plugs 33 to prevent the round tube from causing harm to the operator.

[0035] The handle bar 31 is a telescopic bar, so different lengths can be selected to accommodate people of different heights.

[0036] The wheel stopper 20 is made of flexible materials, including but not limited to rubber, polyurethane, plastic and other materials, has a long service life, can effectively protect the train wheels, and can be replaced when damaged without replacing the entire set of wheel stoppers.

[0037] It can be seen that the advantages of the utility model are:

[0038] 1. It has a long service life and can effectively protect the train wheels. When damaged, just replace the wheel chock instead of the whole set of wheel chocks.

[0039] 2. The handle and the wheel stopper base are split structures and can be disassembled. The handle can be removed after the wheel stopper is installed without affecting the maintenance work around the train. The wheel stopper and the wheel stopper base are fixed with bolts, which is easy to install, reliable in fixing, and easy to replace.

[0040] 3. It has the function of bilateral use and is easy to operate. The wheel stopper is made of flexible material and can be replaced separately. The base plate of the wheel stopper fits well with the top surface of the rail. The handle can be removed and can be replaced with handles of different lengths, which is more adaptable.
