The invention relates to a lifting and transport machinery, namely, stands for testing hoist car catchers.

The purpose of the invention is to reduce metal intensity and increase reliability.

FIG. 1 shows the stand in the initial position, a general view} in FIG. 2-node I in FIG. one; in fig. 3 is a view A of FIG. one.

The stand consists of guides 1 mounted in the shaft, in which the catchable cab 2 moves, equipped with hooks Zo With the guides 1, the beam 4 is rigidly connected, to which the vertical sleeve 5 is rigidly attached. The rod 6 is mounted coaxially to the sleeve 5 and is movable relative to the liner.

The upper end of the rod 6 has a bearing pad 7 for mounting the cab 2 on it, and its lower end is fixed relative to the sleeve by means of a ball lock 8 "The ball lock 8 consists of a sleeve 9 that is movable relative to the sleeve 5 and has a groove Q i B The rod 6 is also filled with a groove B, in which balls 10 are placed, the diameter of which is greater than the depth of the groove S о- In the sleeve 5 there are holes for smashing the sleeve 5 coaxially to the rod 6 an elastic element (spring) 15, located from the stop b overshoot cab

2 up to the moment of tripping of catchers and the way of braking. The ball lock 8 is driven by turning the two-armed lever 13, which moves down the sleeve 9, while the balls 10 release the rod 6. The cabin 2 together with the rod 6 begins to fall until the catchers 3 are triggered.

3 will not work, the energy of the cabin 2 is absorbed by the elastic element 15 and it stops. 3 silt

th; these are indicated balls 10. The lower end of the sleeve 5 is equipped with a flange 11, and between the latter and the sleeve

9 a spring 12 is placed. The ball lock 8 is driven, for example, by means of a two-arm lever 13 fixed to the beam 4, one arm of which is connected to the sleeve 9,

and the other with a rope 14, which rotates the two shoulders of the lever 13 and, consequently, moves down the bushings 9. The rod 6 has an abutment b in the form of a collar, and in the sleeve 5 a resilient element (spring) 15 is installed from the abutment b at a distance exceeding the acceleration path of cab 2 until the time of the catches triggering and the braking path.

The stand works as follows. In the 1x1 direction, a beam 4 is fastened into which the sleeve 5 is fixedly mounted. The rod 6 is in the initial position at the top and fixed to the sleeve by means of a ball lock 8. On the support platform 7 a cabin 2 is installed, installed in the guides 1 Through the two shoulders the lever 13 moves down the sleeve 9 o When this balls

10 fall into the groove Q and release the rod 6 o Cab 2 together with the rod 6 begins to fall to that number, until the catchers 3 do not work. In case the catchers 3 do not work, the energy of the supply cab 2 is absorbed by the elastic element 15 and it stops ,

To bring the stand to its initial state, it is necessary to raise the cab 2, remove the catchers 3 in it, then manually raise the rod 6 until the ball lock 8 is activated and lock the rod 6 relative to the fixed sleeve 5.
