Abstract
The utility model relates to a protective device for an air door of a coal-mining roadway, and the air door is arranged in the roadway. An air door bumper comprises a cross beam and two vertical rods, wherein the vertical rods are fixed on the outer side of the air door in the width direction of the roadway, and distances are formed between the vertical rods and the air door; the distance between the vertical rods is smaller than the length of the cross beam; and one end of the cross beam is arranged on one vertical rod through a vertical rotating shaft, the other vertical rod is positioned between the cross beam and the air door, and the other end of the cross beam is connected with the air door. The protective device for the air door of the coal-mining roadway adopts the rotatable cross beam, and a certain distance is formed between the cross beam and the air door, so that equipment can touch the cross beam when passing through the roadway; and the cross beam is limited by the other vertical rod, so that the air door is protected, the problem that the air door is broken due to collision is avoided, and the service life of the air door is prolonged.
Description
Technical field
The utility model relates to the coal mine roadway safety device, and particularly the tunnel air door specifically is a kind of coal mine roadway air door protector.
Background technology
Air door is the important foundation facility of mine ventilation, is undertaking stable well ventilation system, controls distinguished and admirable short circuit, is guaranteeing each vital task with the wind effective wind rate of production system.If the sealing performance of the air door that mine uses is bad, it is serious to leak out, just may cause usefulness wind places such as getting working face gentle breeze, calm to occur, can not effectively dilute gas and other pernicious gases, even can cause distinguished and admirable short circuit, its result must be ventilation system disorder, operating area gentle breeze and calm.For many years, locomotive transportation in big lane, down-hole often has generation because misoperation breaks the phenomenon of air door, owing to the destruction that air door is caused, also can cause situations such as mine air short circuit, causes the ventilation safety accident.
Summary of the invention
The purpose of this utility model is to provide a kind of coal mine roadway air door protector, and described this coal mine roadway air door protector will solve the technical problem that air door of the prior art is often collided by passing transport vehicle and damage easily.
The purpose of this utility model is achieved through the following technical solutions: air door is located in the tunnel, this air door beam is made of a crossbeam and two montants, these two montants are fixed in the air door outside along the span length direction and also and between the air door are provided with distance, distance between two montants is less than the length of crossbeam, crossbeam one end is located on the montant by vertical rotating shaft, another root montant is between crossbeam and air door, and the crossbeam other end is connected with air door.
The crossbeam other end is connected with air door by wire rope, and wire rope one end of diameter 7.5mm is fixed on the crossbeam, and the wire rope other end is fixed on the air door.
Crossbeam is made of i iron, and the length of crossbeam is 2m, and crossbeam is 0.5m apart from the height on ground, tunnel.
The length of two montants is 1m, and the distance between two montants and the air door is 0.5m.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model adopts a rotary crossbeam in coal mine roadway air door protector; be provided with certain distance between crossbeam and the air door; when passing equipment when the tunnel is passed through; at first can meet this crossbeam; and crossbeam is spacing by another root montant; thereby protected air door, the problem of avoiding air door to be broken, the application life of prolongation air door.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, in the present embodiment, air door 1 is located in the tunnel 2, this air door beam is by a crossbeam 3 and two montants 4,5 constitute, these two montants 4,5 along tunnel 2 widths be fixed in air door 1 outside and and air door between be provided with the distance of 0.5m, two montants 4, distance between 5 is less than the length of crossbeam 3, crossbeam 3 one ends are located on the montant 4 by vertical rotating shaft, another root montant 5 is between crossbeam 3 and air door 1, crossbeam 3 other ends are connected with air door by wire rope 6, wire rope 6 one ends of diameter 7.5mm are fixed on the crossbeam 3, and wire rope 6 other ends are fixed on the air door 1.Crossbeam 3 is made of i iron, and the length of crossbeam is 2m, and crossbeam is 0.5m apart from the height on ground, tunnel.Two montants are made of i iron, and the length of two montants is 1m.
As shown in Figure 2, because the distance between two montants 4,5 is less than the length of crossbeam 3, so the crossbeam other end can be under the stopping of montant, and avoid colliding with air door, thereby protect air door.Simultaneously, when air door is opened, the i iron crossbeam is backed down by the air door self-acting; When air door is closed, make crossbeam and air door close synchronously again by wire rope.
