Abstract
The utility model discloses a coal mine down-hole air door interlocking device, comprising steel cables, blocks, slider bodies, a sleeve barrel, a front fixed plate, a rear fixed plate, a moving block and a pin shaft. The prior art easily causes two air doors open at the same time, thereby, air leakage is generated to destroy the system ventilating in normal. The utility model overcomes the defect existing in the prior art, and adopts the structure that the moving block and two slider bodies link and match. The two slider bodies can not simultaneously slide out of the sleeve barrel at any time, thereby, the two air doors can not be opened at the same time with the function of automatic self locking.
Description
Technical field
The utility model relates to the damper control of ventilation system under a kind of coal mine.
Background technology
At present, the air door of China's coal-mine down-hole ventilation system great majority are for singly opening or two opening structure.For solve under positive and negative aweather two kinds of situations every wind commutation problem, mostly make the structure at positive and negative two sects.The subject matter that this structure exists is: can not realize automatic self-locking between two doors, cause the twice air door to open simultaneously easily, produce air leakage phenomena, the destruction system normally ventilates.
Summary of the invention
The purpose of this utility model is to overcome the defective that above-mentioned prior art exists, and provides a kind of ventilation system that can prevent in the course of the work to leak out, and ensures the device of ventilation system operate as normal.
The technical solution of the utility model is achieved in that it is made up of wire rope, pulley, slide mass, sleeve, front shoe, rear fixed plate, moving block, bearing pin; Front shoe and rear fixed plate fix as one two sleeves, and the pin shaft hole that bearing pin passes on the moving block is fixed on the forward and backward fixed head; Slide mass is respectively charged in the sleeve, and wire rope links to each other with slide body top through pulley; Under the duty, a limit of rotor outline is positioned at sleeve upper edge top, with quill to vertical, and stretch to sleeve center of circle direction, block the part of slide body top; Paste mutually with the slide mass surface is parallel on another limit of rotor outline.
The exterior angle of moving block is 1/4th sections arc surfaces, arc surface and bearing pin concentric.
The structure that has adopted moving block and two slide masses to be linked in the technical solution of the utility model, whenever two slide masses all can not skid off sleeve simultaneously, thereby reach the technique effect of automatic self-locking.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 takes down schematic diagram behind the front shoe for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.By illustrated in figures 1 and 2, the utility model is made up of wire rope, pulley, slide mass (1), sleeve (2), front shoe (3), rear fixed plate, moving block (4), bearing pin; Front shoe (3) and rear fixed plate are fixed as one two sleeves (2) by welding or being spirally connected, and the pin shaft hole that bearing pin passes on the moving block (4) is fixed on the forward and backward fixed head with pin or welding manner; Slide mass (1) is respectively charged in the sleeve (2), and wire rope links to each other with slide mass (1) top through pulley, and the other end of wire rope links to each other with air door; Under the duty, a base of moving block (4) outline is positioned at top, sleeve (2) upper edge, and is axially vertical with sleeve (2), and stretches to sleeve (2) center of circle direction, blocks the part at slide mass (1) top; Paste mutually with slide mass (1) surface is parallel on another base of moving block (4) outline.The exterior angle of moving block (4) is 1/4th sections arc surfaces, and arc surface and bearing pin have the same center of circle.The course of work is: when an air door is opened, driving the slide mass (1) that links to each other by wire rope goes up sliding, slide mass (1) top pushes moving block (4) and makes its upset simultaneously, another slide mass (1) top is blocked in moving block after the upset (4) bottom, because the slide mass (1) that skids off sleeve (2) has earlier limited moving block (4) and can not return and turn over, thereby, also limited another slide mass (1), make it can not go up cunning, also just can not open the air door that links to each other with this slide mass (1) then.After closing air door, slide mass (1) falls back to the origin-location by deadweight, and at this moment, two air doors are in the state opened of all having an opportunity.But in case arbitrary air door is opened earlier, then another air door just can't be opened again, after the air door that only remains to be opened is earlier closed, just can open.That is, can only there be an air door to be opened at any one time, the situation that two air doors are opened simultaneously can not occur.Therefore, realized the function of air door self interlocking.
Claims (2)
1, a kind of coal mine lower wind door interlocking device, it is characterized in that: it is made up of wire rope, pulley, slide mass 1, sleeve 2, front shoe 3, rear fixed plate, moving block 4, bearing pin; Front shoe 3 and rear fixed plate fix as one two sleeves 2, and the pin shaft hole that bearing pin passes on the moving block 4 is fixed on the forward and backward fixed head; Slide mass 1 is respectively charged in the sleeve 2, and wire rope links to each other with slide mass 1 top through pulley, and the other end of wire rope links to each other with air door; Under the duty, a base of moving block 4 outlines is positioned at top, sleeve 2 upper edges, and is axially vertical with sleeve 2, and stretches to sleeve 2 center of circle directions, blocks the part at slide mass 1 top; Paste mutually with slide mass 1 surface is parallel on another base of moving block 4 outlines.
2, coal mine lower wind door interlocking device according to claim 1, it is characterized in that: the exterior angle of moving block 4 is 1/4th sections arc surfaces, arc surface and bearing pin concentric.
