Description

Technical Field

[0001] The utility model relates to the technical field of train braking, in particular to an anti-slip wheel stopper. Background Art

[0002] A wheel skid is a railway safety device used to prevent a train from sliding or losing control. It is usually installed on the track and contacts the wheels to provide a braking effect. When the train wheels step on the iron shoes, the friction between the wheel and the rail is converted into sliding friction, thereby preventing the train from moving forward.

[0003] The wheel stopper lacks a buffer device. Due to the large mass of the train, the inertia generated is also large. When the wheels of the train impact the wheel stopper, it is easy to cause impact damage to the wheel stopper, reducing the service life of the wheel stopper. Summary of the invention

[0004] The utility model provides an anti-slip wheel stopper to solve the problem that the wheel stopper is easily damaged by impact caused by train wheels due to lack of a buffer device on the wheel stopper, and can prolong the service life of the wheel stopper.

[0005] In order to solve the above problems, the technical solution of the utility model is:

[0006] The cam is an arc-shaped protrusion which is located on the left side of the movable seat and has an arc-shaped protrusion facing downwardly. A cross bar is fixed on the right side of the force-bearing plate, and the free end of the cross bar movably penetrates the left side of the groove. A spring is arranged on the outer sleeve of the cross bar in the groove, and one end of the spring is connected to the right end of the cross bar and the other end is connected to the left side of the groove. The right side of the force-bearing plate is connected to a sleeve, and the free end of the sleeve movably penetrates the left side of the groove. The right end of the friction column is rotatably connected to the movable seat on the right side of the groove, and the left end extends into the sleeve. A spiral groove is provided on the peripheral wall of the friction column, and a driving rod is fixed on the inner wall of the sleeve and extends into the spiral groove. Friction plates are provided on the front and rear sides of the friction column, and the two friction plates are located on the right side of the sleeve, and the opposite ends press and contact the friction column.

[0007] Furthermore, the clamping assembly includes a fixed rod, and the front and rear sides of the movable seat are fixed with fixed rods, the fixed rod is slidably connected to a connecting frame, the connecting frame is fixedly connected to a clamping block that cooperates with the track, the fixed rod is fixedly connected to a stopper, and a spring 2 is arranged between the stopper and the connecting frame and is sleeved outside the fixed rod.

[0008] Furthermore, the front and rear edges of the force-bearing plate are arc-shaped edges; the left side surface of the movable seat is an arc-shaped surface corresponding to the force-bearing plate; when the spring is in a natural state, there is a gap between the force-bearing plate and the left side surface of the movable seat; when the force-bearing plate contacts the left side surface of the movable seat, there is a gap between the right end of the sleeve and the friction plate.

[0009] Furthermore, the two friction plates are symmetrical in front and back, the rear end of the front friction plate is an arc surface corresponding to the front part of the peripheral wall of the friction column, the front end is movable through the moving seat on the front side of the groove, a vertical plate is fixed to the front end of the top surface of the friction plate, and a spring three is connected between the vertical plate and the front side surface of the moving seat.

[0010] Furthermore, when the arc surface of the friction plate contacts the friction column, the spring three is in a stretched state.

[0011] Furthermore, the friction column is a cylinder made of metal fiber reinforced material, and the friction plate is a plate made of metal fiber reinforced material.

[0012] Through the above technical solution, the beneficial effects of the utility model are:

[0013] After the force-bearing plate of the utility model is impacted by the train wheel, the force-bearing plate moves toward the moving seat, and the spring 1 is stretched, so that a part of the impact energy of the wheel is converted into the potential energy of the spring 1; in the process that the sleeve moves with the force-bearing plate, it can drive the friction column to rotate, so that a part of the impact energy of the wheel is converted into the internal energy between the friction plate and the friction column, and then it can provide a buffering effect, so that the energy directly acting on the moving seat by the wheel is weakened, the impact damage of the wheel on the utility model is reduced, and the service life is increased.
