Safety device of flexible tramcar

Abstract

The invention discloses a safety device of a flexible tramcar. The safety device of the flexible tramcar comprises a frame arranged at the bottom part of the tramcar, wherein at least one baffle block is arranged on a track of a horizontal lane in a mine; a rotatable drawbar hook is arranged below the frame; a rotatable cam top block, a slide bar and a bolt seat are arranged above the frame; a toggle bar is connected to the slide bar; a lever device is arranged between the slide bar and the drawbar hook; the safe drawbar hook at the bottom part of the tramcar falls off to hook a sleeper, so as to prevent the hollow tramcar from advancing when colliding the baffle block if the bolt is not well inserted into the hollow tramcar when the hollow tramcar slides on the track of the horizontal lane; the tramcar can smoothly slide on the track of the horizontal lane only when the bolts are well inserted into all hollow tramcars, and then can enter the track of an inclined shaft to slide downwards; the tramcar stops sliding after colliding with the baffle block if the bolts are not well inserted; one baffle block is arranged on the track of the horizontal lane at an interval of a certain distance; and a plurality of baffle blocks are arranged, so that no risk at all is ensured; and the security is high.

Description

technical field

[0001] The patent of the present invention relates to mining machinery, in particular to a safety device for a flexible mine car. Background technique

[0002] Inclined shafts are the main traffic lanes for mining and transporting mines. There are many inclined shafts in some mines, and inclined shafts are drilled below the inclined shafts. There is no uniform standard for the slope of the inclined shaft, ranging from more than 30 degrees to more than 40 degrees, and its depth varies from tens of meters to thousands of meters. There is a large horizontal walkway above each inclined shaft, which is equipped with tracks and electric winches, and mine cars are placed on the tracks. The tracks are divided into heavy mine cars and empty mine cars. Put it on the loadway, and put the empty mine car on the empty driveway. When the winch pulls the heavy mine car up from the inclined shaft, the worker pulls out the bolt, and the wire rope on the winch is separated fr...
