Abstract

PROTECTIVE DOOR OF THE PROTECTION OF THE CELLWARE OPENINGS OF MINE STEMES in auth. 471273, the aim of which is to increase the safety of work, the support stand, installed with the possibility of interacting with the lateral side of the sash, and on the beam located at an angle in the zone of its hinge connection with the other beam, a ledge placed with the possibility of its interaction with the sash suspension roller.

Description

This invention relates to a shaft aperture.

According to the main auth. W 471273, a known safety door for fencing cage openings of shaft shafts, comprising two leaves, each of which is suspended on rollers with the possibility of moving a guide frame mounted on the stand of the interface machine and made in the form of two beams arranged at an angle to one another, moreover, the rays of the guide frame are interconnected by means of a horizontal hinge.

The disadvantage of the device is the possibility of opening the valves manually and thereby creating a danger of a person falling into the trunk.

The purpose of the invention is to increase the safety of work.

This goal is achieved by the fact that in the safety door of the cage openings of the shaft shafts includes two shutters, each of which is suspended on rollers with the POSSIBILITY of movement along the guide frame mounted on the stand of the conjugation machine and made in the form of two beams at one angle to the other, where the rays of the guide frame are interconnected by means of a horizontal hinge, the linkage stand has a stop installed with the possibility of interaction with the side of the leaf, and on the beam, At an angle in the swivel zone with another beam, a step is made, which is arranged to interact with the sash suspension roller,

Figure 1 shows the proposed door in the closed position, the OSES view; Fig.2 - a door with an open left sash and tilt up the beam

right sash; in Fig. 3 and 4, the hinged connection of the rays and their conjugation in Fig. 3 is a section along the hinge.

The door consists of two wings 1, each of which rolls on rollers 2 along its frame & 3, consisting of two beams 4 and 5, interconnected by a horizontal hinge b and fixed by device 7, with an inclined beam; 5 forms a step 8 with the horizontal beam 4, which is a lock for the movement of the rollers when the beam 4 is horizontal. The beam 4 is supported through the fork 9 on the bracket 10, through which the rod 11 passes, transmitting the force from the pneumatic cylinder 12 to the guide frame. The pneumatic cylinder 12 and the bracket 10 are rigidly connected to the stand 13 of the machine tool. On the same rack

the bracket 14 of the hinge 15 is fixed rigidly 16. The hinge b consists of two kerchiefs 17 fixed to the beam 5 and one kerchief 16 fixed to the beam 4, interconnected by an ISt sleeve. The latter is loosely mounted on the axis 20, which is cantilever-mounted on the middle rack 21 of the mating machine. The device 22 is located on the axis 20, preventing the sash from sliding. The racks 13 are fixed to the stops 23, located opposite the end of each sash, with the possibility of sliding along the end of the sash as they move 3 vertical planes.

The device works as follows t

In the absence of a crate, the doors are in the closed position. At this time, the beam 4 is in a horizontal position and the ledge 8 does not allow the sash to be opened manually, as the roller 2 rests on this ledge and cannot hit it. When the cage reaches the horizon, Pneumatic cylinder 12 is turned on, the rod of which rises up. The slide in the bracket 10, the rod with its upper end lifts the beam 4 upwards, while the flap 1 also begins to rise, as the ledge 8 interferes with its rolling to the right, and the stop 23 does not allow the flap to deviate from the horizontal position. As a result of this, the right roller of the sash begins to lift, and as soon as it rises to the height of the ledge, the sash will start rolling right from beam 4 to beam 5 until beam 5 is in a horizontal position. In such a position, the door is open for people to leave the cage or exchange trolleys.

When the piston of the pneumatic cylinder 12 moves, the sash will start moving to the left. The left sash roller moves unimpededly along beam 4, and the right roller, having reached step 8, hangs over it and begins to descend onto beam 4 together with the leaf.

Similar to the work and the right door leaf. When approaching the stand with the length gauge, the safety device 22 is removed, the left flap is moved to the left, while the guide frame 3 rotates the axis of the axis passing through the hinge 15, the bracket GO, the rod 11 and the axis of the pneumatic cylinder 12, then release the fixing device 7 and rotate beam 5 relative to the horizontal hinge b to the right. In this position, the left opening is ready to skip the length gauge. The closure of the opening is reversed.

The proposed technical solution increases the safety of the operation of the safety doors, since it eliminates the possibility of opening them manually and improves the operation of the structure due to the smooth rolling of the leafs on the rollers each in its own way. ,
