Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining electromechanical transportation technology, and in particular to a vehicle stopper, specifically a vehicle stopper for mining car ramps. Background Technology
[0002] Rail transport has many advantages, such as simple structure, large carrying capacity, long transport distance and high reliability. It is widely used in various industries, especially in coal mines, where a large amount of transportation relies on rails.
[0003] Mobile substations are installed in the transport roadways of fully mechanized coal mining faces. Each equipment train consists of ten flatbed cars. As the working face advances, the entire train needs to be moved along the tracks to a designated location. When moving, the train requires a wheel stop. In existing technology, the wheel stop head can only stop the wheels of the flatbed cars, typically set at a height of about 10 centimeters. While this works on level ground, most roadways have steep inclines. When stopping on the downhill section of the slope, the existing wheel stop is ineffective, easily causing the car to jump or run away, resulting in loss of control of the flatbed car. Summary of the Invention
[0004] This invention addresses the problem that current car stoppers have insufficient height, can only stop the wheels of flatbed cars, and cannot adapt to slopes in tunnels. On the downhill section of the slope, the car stopper fails to stop the car, leading to the car jumping off the road, running away, and a series of other problems, causing the flatbed car to lose control. This invention provides a car stopper for mine car slopes.
[0005] This utility model is achieved using the following technical solution:
[0006] A car stop for a mine car ramp includes a support base with a rail groove on its side wall to accommodate a rail. The top plate of the support base has mounting holes symmetrically arranged on both the inner and outer sides of the rail. An L-shaped clamp is located below the mounting holes on the support base. The support base is fitted onto the rail with the L-shaped clamp and secured with bolts. The free edge of the vertical surface of the L-shaped clamp rests on the lower surface of the support base, and the free edge of the horizontal surface of the L-shaped clamp is fitted onto the rail neck. The support base includes a front support and a rear support arranged in parallel. The front and rear support bases are fixedly connected by a cross brace. A car stop rail is fixed in the middle section of the front support base, and an inclined car stop rail brace is fixed between the upper part of the car stop rail and the rear support base.
[0007] In implementation, the system includes a support base with a rail groove on its side wall to accommodate the rails. The support base is made of 12# channel steel and spans two rails. The top plate of the support base has symmetrical support base mounting holes on both the inner and outer sides of the rails, that is, each support base has four support base mounting holes. Below the support base mounting holes, there is an L-shaped clamp. The width of the L-shaped clamp is smaller than the width of the top plate of the support base. That is, the L-shaped clamp is installed between the side walls of the support base. The support base and the L-shaped clamp are clamped onto the rails and fixed with fastening bolts. The L-shaped clamps on the left and right sides of the same rail and the support base are fastened together to form a complete rail cavity.
[0008] The free edge of the vertical plate of the L-shaped clamp is mounted on the lower surface of the support base, and the free edge of the horizontal plate is clamped on the rail neck. The horizontal plate of the L-shaped clamp has a clamp mounting hole facing the support base mounting hole. A nut is welded below the clamp mounting hole, and the nut cooperates with the fastening bolts that pass through the support base mounting hole and the clamp mounting hole in sequence.
[0009] As an alternative, the L-shaped clamp is made of thick steel plate, with threaded holes made in the horizontal clamp of the L-shaped clamp.
[0010] With the direction facing the flatbed car as the front, the support base includes a front support base and a rear support base arranged in parallel. The length of both the front and rear support bases is greater than the distance between the rails. The front and rear support bases are fixedly connected by a support base cross brace. The front and rear support bases and the support base cross brace form a stable support base. The base is rectangular. A car stop rail is fixed in the middle section of the front support base. Specifically, the car stop rail includes a pair of car stop longitudinal frames, which are vertically fixed on the front support base. A car stop crossbar is fixed between the two car stop longitudinal frames. A reinforcing rib is fixed between the center of the car stop crossbar and the front support base. To facilitate installation, save materials, and improve the strength of the car stop, the distance between the two car stop longitudinal frames is less than the distance between the support base mounting holes located on the inner sides of the two ends of the front support base. An inclined car stop rail diagonal brace is fixed between the upper part of the car stop rail and the rear support base. The angle between the car stop rail diagonal brace and the support base cross brace is 30~60°. Optimally, the angle between the car stop rail diagonal brace and the support base cross brace is 40°.
[0011] Compared with the prior art, this application has the following advantages:
[0012] This utility model provides a mine car ramp stopper that, through its heightened barrier design, effectively prevents mine cars from derailing and jumping off the tracks. It offers high safety, a simple and robust structure, and can be manufactured at low cost using ordinary steel, supporting self-processing and installation. It is also compatible with various mine car models, making it widely applicable. Furthermore, the stopper features a quick-release structure, allowing for rapid movement as the mine car's position changes. Installation and disassembly require only one step, flexibly adapting to different track position fixing needs, significantly improving operational efficiency. For short-distance movement, simply loosening the fastening bolts is sufficient; complete removal is unnecessary, making it convenient and quick.
[0013] This utility model is applied to the 15016 longwall mining face. After being fixed, it fits tightly with the track without slippage. After braking, the maximum sliding distance of the car stop on the track is 0m, and there is no phenomenon of car jumping or running away. It completely solves the hidden dangers of loosening and slippage of traditional temporary car stops. Its stability and reliability are significantly improved. It can not only firmly block mine cars, but also dynamically ensure the safety of parking on slopes. It takes into account both convenience and safety, and provides a higher level of safety benefits for mine car operations. Attached Figure Description
