Abstract
The utility model discloses a locking device between underground air doors. A square iron cylinder is fixed between two air doors through a cement platform, two pulleys are fixed right above the square iron cylinder, two square column hanging blocks are arranged inside the square iron cylinder in parallel, a right angle baffle device which can swing in a left-and-right mode is arranged on the top face of the square iron cylinder and between the two square column hanging blocks, the two square column hanging blocks are respectively provided with a locking line, and two locking lines are respectively tensioned on an adjacent air door after winding around the pulleys of the locking lines respectively. When one of the air doors is opened, one square column hanging block is driven to expose from the top face of the square iron cylinder, and at the moment, the right angle baffle device is forced to swing to the other side to press on the other square column hanging block so that the square column hanging block cannot be opened. Only when the other air door is opened, and the right angle baffle device swings freely to enable the hanging block at the other side to be lifted, the other air door can be opened, and therefore locking of the two air doors is realized.
Description
Technical field
The utility model is related to underground air door.
Background technology
In underground coal mine ventilating system, according to ventilation needs will air door, to avoid divulging information in pedestrian, driving conditions, typically set the adjacent air door of twice, another closed mode when opening.However, often there is a situation where that someone does not note making twice air door open simultaneously, Air escape branch is caused, causes distinguished and admirable disorder.
The content of the invention
To solve the problem of twice air door is opened simultaneously, the utility model provides the blocking device between a kind of underground air door, and when realizing one of air door opening, another road air door can not be opened.
To reach above-mentioned purpose, the utility model is adopted the technical scheme that：A kind of blocking device between underground air door, it is to fix a square work durm with cement platform between twice air door, two pulleys are fixed directly over square work durm, two square column pendants are placed in square work durm side by side to stick together, a square buffered tower swung is installed between two square columns pendant of square work durm top surface sticks together, two square column pendants are sticked together and are respectively equipped with locking line, and two locking lines are bypassed after respective pulley respectively, are tensed respectively on the air door closed on.
Illustrate advantage of the present utility model below according to operation principle：When opening wherein one of air door, the top surface for driving square column pendant to stick together from square work durm exposes, square buffered tower is now forced to swing to opposite side, it is pressed on another square column pendant sticks together, makes to open, only road air door closes square column when falling, square buffered tower freely swings, make opposite side pendant stick together to lift, so that another road air door could be opened, so as to realize the locking between twice air door.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram；
Fig. 2 is the attachment structure enlarged drawing of square work durm and square buffered tower.
In figure, the square work durms of 1-, 2- left chain wheels, 3- right pulley, 4- lefts post pendant sticks together, and post pendant in 5- rights sticks together, 6- square buffered towers, the left air doors of 7-, the right air doors of 8-.
Embodiment
As shown in Figure 1, a kind of blocking device between underground air door, it is to fix a square work durm 1 with cement platform between twice air door, fixed left chain wheel 2 and right pulley 3 directly over square work durm 1, placed side by side in square work durm 1 left post pendant stick together 4 and right post pendant stick together 5, sticked together in the left and right square column pendant of the square top surface of work durm 1 between 4 and 5, one square buffered tower 6 swung is installed, left and right square column pendant, which sticks together, 4 and 5 is respectively equipped with locking line, and stick together 4 locking line of left post pendant is bypassed and tensed after left chain wheel 2 on left air door 7；Stick together 5 locking line of right post pendant is bypassed and tensed after right pulley 3 on right air door 8.
