Abstract

The utility model discloses an air door interlocking rope tightening device, which comprises a shell, wherein sliding grooves are formed on an upper wall and a lower wall of the shell; a left end in the shell is fixedly provided with a first static pulley; a movable pulley is arranged inside the shell; two ends of the movable pulley are positioned inside the sliding grooves; a tension spring is fixedly connected with the movable pulley; the other end of the tension spring is fixedly connected to the right end in the shell; a second static pulley is fixedly arranged in the sliding grooves and is positioned between the movable pulley and the first static pulley; a positioning bolt and a limiting bolt are fixedly arranged in the sliding grooves; the positioning bolt is positioned on the right side of the second static pulley; the limiting bolt is positioned on the right side of the movable pulley; and an outer face of the shell is fixedly connected with a fixing claw. The air door interlocking rope tightening device is arranged in the middle of two air doors, when the air doors are opened, an interlocking rope stored in the rope tightening device is pulled out by means of opening force of the air doors, the air doors are opened, and pedestrians and vehicles safely pass through; and when the air doors are closed, the rope tightening device stores excessive interlocking rope by means of own tightening force, and a phenomenon that the air door interlocking rope is too long is effectively eliminated.

Description

Air door interlocking euphroe
Technical field
The utility model relates to a kind of mining device, relates in particular to a kind of air door interlocking euphroe.
Background technology
The air door interlocking main pulley type interlocking that uses in present mine is restricted, and the interlocking rope is hung and prolonged the positive silk tense wire rope of employing, promptly fixedly hangs the rope of interlocking with thin wire, or adopts the gate interlock rope of keeping watch to penetrate fine steel tube and hang method, or on the air door wall, orders pulley and interlock.Adopt this method of hanging, though can realize the requirement of underground air door interlocking, this operation causes the frictional force of air door interlocking rope big; Cause air door interlocking rope serious wear, cause the interlocking fracture of rope easily, thereby do not have the interlocking effect; The thin wire corrosion fracture of making moist easily simultaneously causing the interlocking rope to come off, and does not equally also have the interlocking effect; Cause air door interlocking rope to change, keep in repair frequently, even cause the twice air door to open simultaneously, make the distinguished and admirable short circuit of work plane; Threaten staff's life security, bring great loss for colliery enterprise.
Summary of the invention
The purpose of the utility model provides a kind of air door simple in structure, safe and convenient to use interlocking euphroe.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of air door interlocking euphroe; Comprise shell, the upper wall and the lower wall of shell have sliding tray, it is characterized in that: the left end in the shell is installed with the first quiet pulley; Be provided with movable pulley in the shell; The two ends of movable pulley are positioned at sliding tray, are fixedly connected with extension spring on the movable pulley, and the other end of extension spring is fixedly connected right-hand member in the enclosure.
According to described air door interlocking euphroe, it is characterized in that: be installed with the second quiet pulley in the said sliding tray, the second quiet pulley is between the movable pulley and the first quiet pulley.
According to described air door interlocking euphroe, it is characterized in that: be installed with pilot pin and caging bolt in the said sliding tray, pilot pin is positioned at the said second quiet pulley right side, and caging bolt is positioned at said movable pulley right side.
According to described air door interlocking euphroe, it is characterized in that: said enclosure is fixedly connected with fixed claw.
The utility model is installed in the middle of the twice air door, when air door is opened, relies on the opening force of air door to pull out the interlocking rope that stores in the euphroe, and door opening, pedestrian and vehicle safety pass through.When air door was closed, euphroe relied on the expanding force of self, and unnecessary interlocking rope is stored, and had effectively stopped the appearance of the long phenomenon of air door interlocking rope, and is simple in structure, safe and convenient to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing:
1, interlocking rope; 2, the first quiet pulley; 3, shell; 4, the second quiet pulley; 5, pilot pin; 6, sliding tray; 7, movable pulley; 8, caging bolt; 9, extension spring; 10, fixed claw.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of air door interlocking euphroe, as shown in Figure 1, comprise shell 3; The upper wall of shell 3 and lower wall have sliding tray 6; Left end in the shell 3 is installed with the first quiet pulley 2, is provided with movable pulley 7 in the shell 3, and the two ends of movable pulley 7 are positioned at sliding tray 6; Be fixedly connected with extension spring 9 on the movable pulley 7, the other end of extension spring 9 is fixedly connected on the right-hand member in the shell 3.In the present embodiment, be installed with second quiet pulley 4, the second quiet pulleys 4 in the sliding tray 6 between the movable pulley 7 and the first quiet pulley 2.Be installed with pilot pin 5 and caging bolt 8 in the sliding tray 6, pilot pin 5 is positioned at the said second quiet pulley 4 right sides, and caging bolt 8 is positioned at said movable pulley 7 right sides.Shell 3 fixed outside are connected with fixed claw 10.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design concept, common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model; The technology contents that the utility model is asked for protection all is documented in claims.
The utility model is applied to the mine ventilation security fields, and making before and after the door opening can automatic interlock, has stopped the phenomenon that the twice air door can be opened simultaneously, has guaranteed the stable of district ventilation system, has guaranteed staff's life security.Can also avoid because of restrict long cause scrape people's phenomenon, increase the safety factor of pedestrian's driving.
The utility model makes before and after the door opening can automatic interlock, has kept the stable of mine ventilation system, helps the safety in production of mine, compares with other air door interlocks, more pays attention to improving the safety of air door interlocking.In addition, can reduce wearing and tearing tension, help economical with materials steel wire.
