Mine car arrester

Abstract

The invention relates to a mine car arrester, which comprises an outer arm and an inner arm; An upper end of that out arm and an upper end of the inner arm are respectively provide with connecting holes; An upper end of that out arm and an inner arm are connected with each other by nail bolts; The upper part of the inner arm is provided with a pillow beam for receiving the shearing of the wheel rim of the mine; The upper part of the outer arm is butted to the pillow beam with a stop; The sleeper beam includes a sleeper surface that coincides with the rail head surface and resists shearing of amine wheel; A locking block is arranged on the lower inner side of the inner arm. A mine car stop of that invention fastens the car stop into an integral body and is jacketed on the rail head of therail through nail bolts, and the car stop does not detach from the rail in any case; The car arrester can be rotated integrally under the impact of the wheel rim of the mine, so that the four lockingsurfaces can be reliably contacted with the lower part of the rail head and the upper part of the rail bottom, and the manufacturing cost is low; operation is easy, only two bolts need to be tightenedduring installation; the mine car arrester is light in weight, easy to carry, no need for maintenance and repair, high reliability of vehicle blocking.

Description

technical field [0001] The invention relates to a temporary vehicle stop device required for track leveling operations, in particular to a mine car stop device. Background technique [0002] Mine trucks are the most widely used major transportation equipment in industries such as mines and building materials. They are responsible for the important transportation tasks of various materials, equipment, coal, ore, timber and other products as well as personnel. Operations in rail roadways, such as the installation, maintenance and repair of various pipes, wires, cables and equipment and facilities, are the main daily work of maintenance personnel in mining enterprises. In order to ensure safety, the company strictly stipulates that before the operation, a vehicle blocking device should be installed at both ends of the work place. Over the years, research on vehicle arresters has never ceased. There are various structures and types of fixed-mounted vehicle arresters, and they a...
