Description

The invention relates to the field of lifting and transport machinery, in particular to elevators, and is an improvement of the invention according to the author. No. 1261233. The purpose of the invention is to increase the reliability of work.

FIG. 1 shows the elevator, a general view; in FIG. 2, node I in FIG. 1, in FIG. 3 - the same, in the process of spontaneous lowering of the overloaded cabin; in fig. 4 shows section A-A in FIG. 2 ..

The elevator contains a cab 1 and a counterweight 2, which are connected by a pull rope 3, the enveloping traction head pulley 4 of the winch 5. A speed limiter 6 is installed in the shaft with a power rod 7 which is kinematically connected to the safety gear 9.

Cab 1 is equipped with a load monitoring device 10 having a sensor detecting the excess of the operating load limit to which the magnetic diverter 1 1 is connected.

The mechanism for engaging catchers has, lever 12, interconnected with wedges 13 catchers and rigidly connected with shaft 8.

An additional mechanism 9 is included catchers contains a four-link consisting of a link 14, rigidly connected with the shaft 8, pivotally connected to it the shackles 15 and 16, the second ends of which are pivotally connected to the rod 17. One end of the rod 17 is equipped

tick device 10 control boot. Magnetic pickup 11 receives a signal from the specified sensor and its pusher acts on the support bar 18 of the rod 17. Due to the fact that the link 14 and the earrings 15 and 16 are connected to each other and pivotally to the rod 17, it is extended.

When the elevator control circuit is broken, the cab cannot be moved from the control panel.

If cab 1 continues to load

and the overload reaches such a value that the tow ropes 3 begin to slip along the traction supervisor. pulley 4, the cab begins to descend spontaneously. In this movie 19,

mounted on the rod 18, which is in the open position from the impact of the magnetic layer 11, interacts with one of the lugs 20 installed in the mine

in the area of this stop. Upon further lowering of the cab 1, the rod 17 will turn around the shaft 8 of the safety mechanism engaging mechanism.

Together with the shaft 8, the levers 12 rigidly connected with it rotate, which, when rotated, will raise the wedge 13 of the catchers to contact with the guide, i.e. cabin with children on catchers.
