Problems solved by technology

However, the bottom lift method of the ZL200810024399.1 patent introduces a car barrier that is opened by the bottom lift method. In the lifting of the mine infinite rope or shuttle car, the hoisting wire rope presses the car barrier and cannot be opened well, so the scope of application has certain limitations.

Abstract

A bottom lifting type U-shaped tram guard comprises a buffer, a steel cable, and a baffle screen which comprises a baffle screen framework and a connecting support; a baffle screen receiving chamber is arranged below a tram road of a well lane; a track bridge which can be opened and closed is arranged above the baffle screen receiving chamber; a baffle screen lifting mechanism is arranged on a side part of the baffle screen receiving chamber; the baffle screen is provided with a left part, a right part and a middle connecting trough plate; the connecting trough plate is provided with a notch through which the tramcar lifting wire cable passes when the baffle screen lifts; a reinforcing plate is arranged on the edge of the notch of the connecting trough plate; and the connecting trough plate is provided with anti-slip teeth which are vertical to the connecting trough plate and prevents the baffle screen from slipping from a locked tramcar. A robe pile is arranged on a connecting position between both sides of the connecting trough plate and the baffle screen framework. In the situation that the lifting wire cable presses the tram guard, the tram guard is guaranteed to open in place, and the application range of the bottom lifting type U-shaped tram guard is expanded; and the bottom lifting type U-shaped tram guard can be applied in an endless rope, a shuttle tram or double-rail hoist, and has good application prospect.

Description

technical field [0001] The invention relates to a mine inclined shaft rail transportation technology, in particular to a bottom-lifting U-shaped barrier. Background technique [0002] The mine inclined shaft rail transportation that this patent relates to is that the mine car is pulled by a hoisting winch to lift materials along the track laid in the inclined shaft. In the process of lifting and lowering the material, due to various reasons, the lifted mine car may be out of traction control. The out-of-control mine car slid down the track rapidly, damaging the shaft facilities and posing a great threat to the lives of the staff in the disembarkation yard. Therefore, the sports car protective device is a very important safety measure, and the barrier is the most important part of the sports car protective device. [0003] At present, the barrier of the sports car protection device that has been commercialized is basically a flexible barrier that adopts a wire rope net. Ac...
