A kind of brake car for inclined lane rail transport

Abstract

The invention discloses an inclined roadway rail transport braking car. The inclined roadway rail transport braking car comprises a car cover, a car frame, a movable shaft wheel pair, a fixed shaft wheel pair, four brake cylinders, rockers, four sets of wedge-shape box brakes and a braking buffering device at least; the left and right of the front side of the fixed shaft wheel pair at the front end of the car frame of the braking car are respectively and symmetrically provided with one set of wedge-shape box brakes, the left and right of the position between the two wheel pairs are respectively and symmetrically provided with one set of wedge-shape box brakes, the four brake cylinders are respectively inclined at a certain angle relative to the car frame and are symmetrically distributed on two sides of the central surface of the car frame and the inner sides of the four sets of wedge-shape box brakes, and piston rods of the four brake cylinders are respectively connected with a flat shaft of each wedge-shape box brake through the corresponding rocker; when inclined roadway rail transport braking car operates, the braking car is connected above a line of cars, the operating speed of the line of cars is extracted through a speed measuring wheel, and therefore when the line of cars operates at excessive speed, a car-mounted hydraulic system automatically controls the brake cylinders to conduct pressure relief simultaneously, the four sets of wedge-shape box brakes are pushed to conduct braking simultaneously by the brake cylinders, and namely synchronous, immediate, safe and automatic braking of the cars can be achieved. The inclined roadway rail transport braking car is simple in structure, does not need an extra power source, has large braking force, and achieves immediate, synchronous, stable and reliable braking.

Description

Technical field: [0001] The invention relates to a brake car for inclined track transport, which is especially suitable for braking mine cars for inclined track transport in coal mines and metal and nonmetal mines. Background technique: [0002] In order to reduce or avoid the hazards of sports car accidents in inclined shafts, in accordance with the requirements of the "Safety Regulations for Coal Mine" and "Safety Regulations for Metal and Nonmetal Mine", protective devices for sports cars are installed on the transportation lines of inclined shafts, so the problem of anti-sports cars in inclined shaft rail transportation is always It is a very important safety issue in the safety production of coal mines and metal and non-metal mines. [0003] "Three gears on one slope" is the anti-sports car solution mostly used in inclined lane rail transportation. The so-called "three blocks on one slope" refers to setting a car barrier or a car net at the upper, middle, and lower par...

AI Technical Summary

Problems solved by technology

[0004] The traditional "one slope and three gears" anti-sports car device cannot block or brake the convoy of cars at the first time when a mine car occurs. Completely eliminate sports car accidents

The Chinese patent announcement number is CN102259651B, which discloses an active anti-sports car device. The device uses a primary brake and a secondary brake. When the primary brake operates, the wheels and the track will slide relative to each other, which is easy to generate sparks.

The Chinese patent announcement number is CN201124828Y, which discloses an automatic anti-running braking vehicle for inclined shafts. The drum brake installed on the wheel hub is braked by the hydraulic brake transmission mechanism, thereby braking the wheel. The braking force of this braking device is small. , after braking, the wheels will still slide with the track, unable to brake the tandem cars running down, and sparks are likely to be generated when the wheels and the track are braked
