Problems solved by technology

This method of opening and closing the mesh block is because the mesh block and the steel wire rope occupy the space on the top and both sides of the roadway. Lifting and landing between the top and the track, the opening and closing stroke is long, so that the opening time is long in advance, forming a large protective dead zone

Embodiment 1

[0026] The present embodiment is accomplished in this way, a bottom lift type car barrier is composed of a buffer 1, a steel wire rope 2, a net 3, a lifting mechanism 4, a track bridge 5, a base 6, a net stick connection support 7, and a track 8 ( See accompanying drawing 1, 2).

[0027] Wire rope 2 passes through retaining net 3 two ends and is respectively connected to buffer 1 on both sides of track, retaining net 3 is connected with lifting mechanism 4, track bridge 5 is above base 6, and base 6 is connected with track 8. The lifting mechanism 4 can open or close the screen. When the retaining net was in the closed state, the rail bridge 5 was attached to the base 6, and the retaining net was in the net retaining chamber 23 below the rail bridge 5, and the hoisting mine car passed through the rail bridge 5. Track bridge 5 is opened when opening, and hoisting mechanism 4 opens screen 3 . When the mine car sports car, the head car hits the net 3, so that the net 3 is disen...

Embodiment 2

[0031] In this embodiment, the connection support is integrated with the track bridge. Rail bridge 5 plays the effect of net stick connection support 7 again, and cylinder 9 promotes retaining net 3 to rotate around rotating shaft 11 through power arm 10, and rail bridge 5 is connected with rotating shaft 11 by the shear pin that can be cut off. When the runaway mine car bumped into the barrier, the net 3 would disengage from the track bridge 5, and the track bridge 5 would fall down under the impact of external force to cut off the shear pins that it was connected with the rotating shaft 11, so as to prevent the track bridge 5 from being damaged.

Embodiment 3

[0033] In this embodiment, the mesh sticks are connected by soft link chains. When the retaining net falls, it can be folded in the retaining net storage chamber 23. Block net 3 is fixed on tackle 19 by screw or iron wire and is pulled by traction rope, and column 18 leads tackle 19, and pulley 17 changes traction direction. The track bridge 5 is connected with the shaft 16 , and the finger 13 and the balance arm 14 are connected with the shaft 16 . The balance arm 14 and the spring 15 are used to adjust the balance state, so that the track bridge will not fall naturally.

[0034] Working principle: when the block net 3 is opened, the tackle moves up, the driving rod 12 fixed on the tackle leaves the finger 13, the track bridge 5 is opened and maintained under the action of the balance force, and the block net is in an open state. When the retaining net 3 is closed, the tackle moves down, and the retaining net 3 is folded in the retaining net storage room 23 below the track ...

Abstract

A vehicle hurdle of a bottom raised type is provided, which comprises a buffer, a wire rope and a baffle screen; two ends of the baffle screen are connected with the buffer fixed at two sides of tramroad by the wire rope; a baffle screen holding room is arranged at the lower part of the tramroad of mine working, the upper part of which is provide with a rail bridge which can be started and stopped; the side part of the baffle screen holding room is provided with a baffle screen lifting mechanism. The rail bridge can be started by a starting and stopping mechanism arranged at the side of the baffle screen holding room and can also connect the baffle screen and can be lifted with the baffle screen. The baffle screen can adopt a rotation starting method or a vertical lifting method. The wire rope of the buffer screen is arranged on the ground of two sides of laneway; the buffer screen moves under the rail and the height of the moving is lower than the height of tramcar, which takes no space at the top and two sides of the laneway; as the baffle screen is not started to place and the material of the mine vehicle is too wide, the baffle screen can not cause mine vehicle to scrap the screen. furthermore, as the starting and stopping travel of a bottom raised type buffer screen is shorter than a top raised type buffer screen, the start-up time is shortened, dead work space is effectively reduced and protection scope for running vehicle is increased.

Description

technical field [0001] The invention relates to a protective device for a sports car in an inclined shaft of a coal mine, in particular to a bottom-lifting type barrier. Background technique [0002] In the mine inclined shaft track transportation that this patent relates to, the mine car is pulled by a winch along the track laid in the inclined shaft to lift materials. 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, sports car protection is a very important safety measure, and the barrier is the most important part of the sports car protection device, whether it can stop the sports car is the key. Inclined shaft sports car accidents are random, irreproducible, and instantly destructive, so it is difficult to study thi...
