Abstract

The utility model discloses a mining air door mechanical lock, which comprises a lock casing (1). Fixed feet (3, 7, 10 and 11) are arranged outside the casing, an angle iron (12) is fixedly connected with the inside of the casing through a bolt (13) to limit ascent of a heavy punch. The mechanical lock is characterized in that two triangles (14 and 15) are sleeved on a shaft post on the lower portion of the angle iron, sliding wheels (2 and 6) which are laterally opposite to each other are arranged on the upper portion of the casing, and two digging lines (4 and 8) are additionally arranged on the casing, one ends of the digging lines are connected with a door leaf, and the other ends of the digging lines are connected with the heavy punches (5 and 9) in the mechanical lock. The mining air door mechanical lock first enables a main body of the lock to be fixed between two doors, and enables steel wire cables and the door to be connected well by fixing on the tunnel wall through the bolt, tightening degree of the two steel wire cables is adjusted to be identical, so that lock purpose can be achieved.

Description

The mine air door mechanical latching

Technical field

The utility model relates to a kind of mine air door device, especially a kind of mine air door mechanical latching.

Background technology

Air door is the mine operation imperative equipment, and it guarantees the tunnel of the required ventilation of distinguished and admirable guiding can be satisfied mine car equipment and personnel on the other hand again and normally comes in and goes out on the one hand; Consider minimizing personnel as far as possible, the distinguished and admirable loss that equipment and mine car are come in and gone out and brought, generally being two sects is one group; Promptly open at a sect, and another sect is closed. the blocking device of existing control door opening or complex structure, and cost of production is high; Performance reliability is poor, is difficult to reach the requirement of accurate synchro switch.

The utility model content

The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, and installation and maintenance are convenient; The mine air door mechanical latching of dependable performance, the purpose of the utility model realizes through following technical proposals: the utility model comprises the locking shell, and hull outside is provided with fixing feet; Is connected with angle steel through bolt in the housing, is used to limit weight and rises, it is characterized in that being socketed with two angle irons on the jack-post of angle steel bottom; The pulley of correspondence about housing top is provided with; Other is provided with two drag-lines, and drag-line one end connects with door leaf, and the other end is connected with the interior weight of mechanical latching.

The utility model is through atretic body and left and right drag-line; Control the open and close of close twice air door, utilize the gravity of weight to realize that the twice automatic door is closed, two weights and drag-line are realized through pulley; Simultaneously because angle iron only allows one to stress the hammer rising; Thereby two weights can not go up and down simultaneously, but one rise and one drop, thereby realize the purpose of adjacent two sect interlockings.

Can know that from above-mentioned situation the purpose of the utility model can realize.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

As shown in Figure 1, the utility model comprises locking shell 1, and hull outside is provided with fixing feet 3,7,10,11; Be connected with angle steel 12 through bolt 13 in the housing; Be socketed with two angle irons 14,15 on the jack-post of angle steel bottom, the pulley 2,6 of correspondence about housing top is provided with, other is provided with two drag- lines 4,8; Drag-line one end connects with door leaf, and the other end passes pulley and is connected with weight 5,9.

Earlier the locking main body is fixed in the middle of two sects during use, through being fixed on the wall of tunnel, the wire rope and the couplet on the door is connected with bolt.Wire rope (4,8)) end connects two sects respectively, and the other end links to each other with the weight (5,9) of locking, when drawing back a sect; Wire rope (4) drive weight (5) moves up to angle steel (12) and locates to stop, and this moment, this door was opened to put in place, the angle iron (14 in the locking simultaneously; 15) block another weight (9); An other sect can not be opened, thereby avoids two sects to be opened simultaneously, after the door people who opens walks; Weight (5) falls back to the home position automatically, and an other like this sect just possibly crossed above-mentioned steps and open.Angle steel (12) can avoid weight degree of being pulled through to play restriction, and angle iron position can pass through bolt (13) and regulate height.

Claims (1)

1. mine air door mechanical latching; Comprise locking shell (1), hull outside is provided with fixing feet (3,7,10,11), is connected with angle steel (12) through bolt (13) in the housing; Being used to limit weight rises; It is characterized in that: be socketed with two angle irons (14,15) on the jack-post of angle steel bottom, the pulley (2,6) of correspondence about housing top is provided with, other is provided with two drag-lines (4,8); Drag-line one end connects with door leaf, and the other end is connected with the interior weight (5,9) of mechanical latching.
