Description

one

The invention relates to mine lifting devices and can be used to equip mines and mines.

The aim of the invention is to reduce the material consumption of the device and simplify its manufacture.

FIG. 1 shows a drum, general view, in section; in fig. 2 shows section A-A in FIG. one; in fig. 3 —Use 1 in FIG. 1 (one option); in fig. 4 - the same, (another option).

A cylindrical split drum consists of a shaft 1 on which a jammed drum part 2 is rigidly seated, containing a shell 3, end walls 4 and a hub 5. On the shaft 1, with a certain clearance relative to the stuck part 2, the adjustable part 6, which has a shell 7, faces wall 8, which is supported on shaft 1 by means of bearing 10 mounted in a bore 9. The latter is made spherical, which allows the mounting part 6 to provide one support point to the shaft 1. The second support point of the moving part 6 is located on the face 4 of the wedged part. The rest of the retractable part is carried out using rollers 11 mounted on the end wall 8 and interacting with the treadmill 12, which is provided with the end wall 4. Adjacent to the rollers 11 on the end wall 8 are stops 13, which are also in contact with treadmill 12. The stops 13 can be made in the form of adjusting screws 14 {FIG. 3) or racks 15, which are hinged on the end wall 8 of the relocatable part and connected to the force cylinders 16. The wedged part 2 is connected to the reversible part 6 when lifting the load by means of the release device 17.

The drum works as follows.

1 When the shaft 1 rotates, the jammed part 2 rotates and the swiveling part 6 connected to it with the help of the release device 17. The rope on which the load is fixed is wound on the shells 3 and 7, the passage through

the gap between them. The uniformity of the gap between the shells is ensured by the stops 13, which also serve to receive the axial forces arising when winding the rope on the adjustable part 6. (In known designs of drums, this force is perceived due to the rigidity of the shaft). Effort with reversible part

through the stops 13 is transmitted to the treadmill 12 of the wedged part 2. When the ropes are pulled, it becomes necessary to adjust them. The adjustment is made by

cranking the wedged part 2 relative to the adjustable part. This rotation is carried out in the following order. The lugs 13 come out of contact with the treadmill 12. If this is the adjustment screws 14, they are unscrewed. When making stops in the form of pillars 15, they are retracted from the treadmill with the help of power cylinders 16. Reusable part 6 disengages

with jammed part 2 including

the release device 17, and slow it down. .

The rotating shaft 1 moves the jammed part 2 relative to the adjustable part 6. At the same time, the rollers 11 roll over the treadmill 12 and maintain an even gap between the shells 3 and 7.

After adjusting the lengths of the ropes, the stops 13 are brought into contact with the treadmill 12. At this point, the loads are already transmitted through the stops 13 and not through the rollers 11. Thus, the loading of the rollers 11 is eliminated by the force from the workload and their durability is increased. After aligning the lengths of the ropes, the drum works in the usual order.

The implementation of the drum with the adjustable part having one point of support on the shaft, and the second on the end wall of the stuck part, allows to ensure uniformity of the gap between the shell 3 and 7 not by increasing the rigidity of the shaft, but by reducing the effect of bending loads on it, arising from the effort in the rope. These loads are perceived not by the shaft, but by the end wall.
