Abstract

The utility model discloses a support stepping type bearing device for a moving equipment train, comprising two motor trolleys which are connected with each other by a traction hydraulic cylinder. Support frames are respectively and vertically arranged at four corner parts of each motor trolley; a hydraulic cylinder is hoisted in each support frame by a spring; and the lower end of the hydraulic cylinder props against the ground surface, and the top end of the hydraulic cylinder props against the top surface of a mine pit. In the support steeping type bearing device, the operation is convenient, the labor force is saved, the work efficiency is improved, and the safety factor is greatly increased when the equipment train is moved.

Description

Supporting stepping mobile equipment train carrying device

technical field

The utility model relates to a mechanical device for moving a mining equipment train, in particular to a supporting device for a stepping moving equipment train.

Background technique

Most coal mining enterprises in the country have moved towards comprehensive mechanized coal mining technology, and modern electromechanical equipment has achieved large-scale, high-speed, continuous and automated. In order to facilitate the management of equipment, coal mining enterprises concentrate the electronic control systems of all equipment in the return air or transportation lane, between 40-150m away from the working face, collectively referred to as equipment trains. Due to the impact of the geological structure, the roadway with a large inclination angle is often arranged straight in sections. Each section of the roadway has up and down slopes. The equipment train has always been drawn by a winch, and the winch needs to be moved every other section on site. The labor intensity of the operators is high. Security is not strong.

Contents of the invention

The purpose of the utility model is to provide a supporting device for a stepping moving equipment train, which has a simple structure and can effectively move the mining equipment train without winch traction. It is easy to operate, saves labor, improves work efficiency, and has a high safety factor. .

The purpose of this utility model is achieved in this way, a kind of supporting step-type shifting equipment train load-carrying device comprises two railcars, and the two railcars are connected by traction hydraulic cylinders, respectively at the four corners of each railcar A support frame is vertically arranged, and a hydraulic cylinder is hoisted in each support frame by a spring, the lower end of the hydraulic cylinder is against the ground, and the top of the piston rod of the hydraulic cylinder is against the top surface of the coal mine tunnel.

When the utility model is in use, the four hydraulic cylinders on the previous rail car work, so that the lower end of the hydraulic cylinder is against the ground, and the top of the piston rod of the hydraulic cylinder is against the top surface of the coal mine tunnel, so that the previous rail car can keep relative Fixed, through the traction hydraulic cylinder between the two rail cars, the latter rail car is pulled forward, and then the hydraulic cylinders at the four corners of the latter rail car work, so that the lower end of the hydraulic cylinder touches the ground, and the piston rod of the hydraulic cylinder The top is against the top surface of the coal mine tunnel, and after the rear rail car is relatively fixed, the four hydraulic cylinders on the front rail car shrink, and under the action of the traction hydraulic cylinder between the two rail cars, the previous rail car is pushed forward, so that Repeatedly and step by step, the equipment train in the coal mine tunnel can move forward by itself without additional traction. The device has a simple structure and a novel concept, can effectively move the mining equipment train, is convenient to operate, saves labor, improves work efficiency, and has a high safety factor.

Description of drawings

The utility model will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is a front structural schematic diagram of the utility model.

Detailed ways

A supporting step-type moving equipment train bearing device, as shown in Figure 1, includes two railcars 1, the two railcars 1 are connected through a traction hydraulic cylinder 3, and the expansion and contraction of the traction hydraulic cylinder 3 is used to change the two railcars. car position. A support frame 5 is vertically arranged at the four corners of each rail car 1, and a hydraulic cylinder 2 is hoisted by a spring 6 in each support frame 5, and the lower end of the hydraulic cylinder 2 is against the ground. The top of the piston rod 4 is against the top surface of the coal mine tunnel. When the hydraulic cylinder piston rods in the support frame 5 are retracted, under the action of the spring 6, the upper and lower ends of each hydraulic cylinder 2 are out of contact with the top surface of the tunnel and the tunnel ground. The utility model has the advantages of convenient operation, labor saving, improved work efficiency and greatly improved safety factor in the process of moving the car.

Claims (1)
