Embodiment Construction

[0013] The steel tank road brake is composed of a suspension device, pipelines and multiple sets of braking units. The suspension device is installed between the hoisting wire rope and the lifting container, and the braking unit is installed on the lifting container. The unit's cylinder connections (such as figure 1 shown). When the hoisting system is in normal operation, the hoisting wire rope always maintains tension under the gravity of the hoisting container and the lifting object, and the oil in the oil cylinder of the suspension device is pressed into the oil cylinder of each brake unit under the tension of the hoisting wire rope, pushing the oil cylinder to extend. Long, overcome the spring force, drive the brake pads to move downward along the slope, out of contact with the steel tank road, the brake does not brake. When the hoisting wire rope breaks, the tension of the wire rope drops rapidly, the oil pressure of the oil cylinder of the suspension device drops accord...

Abstract

The invention relates to a safety braking device for braking on a steel can track brake. A steel can track brake is composed of a suspension device, pipelines and a plurality groups of braking units, wherein the suspension device is mounted between a hoisting steel rope and a hoisting container, the braking units are mounted on the hoisting containers, and a cylinder of the suspension device is communicated with cylinders of the braking units through pipelines. (shown in figure 1) Aiming to solve the security problem which occurs when the steel rope of a vertical shaft hoisting system in the prior steel can track, the technical scheme of the steel can track brake includes that cylinders and a compression spring are driven to release the brake under the stretching force of the hoisting steel rope when the hoisting steel rope is not broken, a braking block is driven to brake under the elastic force of the spring when the hoisting steep rope is broken, the braking block is designed to be a wedge shape (smaller at the top and larger at the bottom), friction force is produced when the braking block contacts with the can track and pushes the braking block to be embedded in the clearance between the can track and a base of the brake, braking force increases until the hoisting container stops on the can track, and thus safe braking is achieved.

Description

1. Technical field [0001] The invention relates to a safety braking device used on a steel tank road (rail), and the braking device is installed on a shaft hoisting container. When the shaft is hoisted normally, the braking device is in the open state (no braking); when the hoisting wire rope breaks, the braking device brakes and stops the lifting container on the steel tank road to prevent tank falling accidents and reduce casualties and property loss. The name of the braking device is steel tank road brake. 2. Technical Background [0002] The vertical shaft is a channel commonly used in mines to vertically transport personnel and materials. The vertical shaft hoisting system consists of a hoist, hoisting containers (cages, skips, etc.), wire ropes, and shaft equipment. The hoist drags the hoisting container through the wire rope to run along the tank road (track) in the shaft to realize the vertical transportation of personnel, goods and ores. In order to ensure the li...
