Abstract

The invention relates to lifting mechanisms, mainly to mechanisms for lowering and lifting a diving bell. The purpose of the invention is to improve the quality of laying rope. A gearbox and a two-piece drum connected with it are installed on the housing. A carriage moves along the drum. On the carriage there are two pairs of rollers through which the guide ropes pass. 2 Il.

Description

The invention relates to lifting mechanisms, mainly to mechanisms for lowering and lifting a diving bell.

The aim of the invention is to reduce the weight and dimensions and reduce costs in manufacturing.

Figure 1 schematically shows a winch, a general view; figure 2 - the same. plan view.

The winch consists of the housing 1, in which the reducer 2 is placed. The drum associated with it has two identical sections 3. On the housing 1, the guide 4 and the lead screw 5 are installed. They have right and left screw cuts on which the carriage 6 is mounted. along the drum 3 with the help of a lead 7. On the carriage 6, two pairs of guide rollers 8 are installed at a given distance of 9. 9. Guide ropes 10. 11 pass from deflecting blocks 12. 13 through a corresponding pair of guide rollers 8. 9 and wound in several layers on a two-piece bar ban 3. having a cylindrical shell 14 and the flanges 15-17.

The winch works as follows.

When lifting the guide ropes 10. 11 two-piece drum 3. rotating, winds the guide ropes on itself

10.11. coming from the deflecting units 12. 13 through an appropriate pair of guide rollers 8. 9. which are mounted on the carriage 6. movable along the spindle screw 5 having a kinematic connection with the drum 3. which ensures the synchronization of the rotation of the drum 3 and the movement of the carriage 6. By this provide a constant step of laying guide ropes and synchronous tight laying of guide ropes 10. 11. This increases the efficiency of multi-layered flexible elements on the drum by increasing the utilization rate of the useful capacity of the drum.

To ensure uniform and synchronous laying of the guide ropes on the two-section drum 3, the distance between the axes of the guide ropes 10.

11. passing through an appropriate pair of guide rollers 8. 9. equal to the distance between the flanges 15. 16 and 16. 17.

The leash 7 is mounted in the carriage in such a way that to ensure its movement along the drum along the lead screw 5 along (L

the latter has a screw right and left cut with a length equal to the difference in distance between the flanges of one of the sections and the diameter of the guide rope.

Claims (1)

Invention Formula A winch for directing ropes of a diving bell, containing a drum, spun out of two sections divided by flanges, and a device for laying guide ropes, which is located parallel to the longitudinal the drum axis and the lead screw kinematically connected to the latter, on which the carriage is mounted with a carriage with a lead, characterized in that, in order to improve the quality of laying the rope, it is equipped with two pairs of guide rollers mounted on the carriage, while the distance between the guide rollers and equal to the distance between the flanges of each of the sections, and the length of the threading of the lead screw is less than the length of each of the sections of the drum by the size of the diameter of the guide rope.
