In the installation, the ropes are connected to the lifting vessels by means of an equalizing hydraulic yctrodust 113. However, this hydraulic device is cumbersome in design and has a relatively small stroke, approximately equal to the length of the working hydraulic cylinder. Due to the fact that the pendant device, the dummy device is inseparably moving along with the vessel being moved, difficulties arise in its control and revision. The small stroke of the leveling device, moreover, leads to a large

Цель изобретени - повышение надежности подъемной установки и улучшение ее эксплуатации.The purpose of the invention is to improve the reliability of the lifting installation and improve its operation.

оabout

Дл достижени поставленной цели уравнительные устройства выполнены в виде конических зубчатых венцов, жестко закрепленных на обращенных друг к другу торцах шкивов соосно с ними, а на валу неподвижно смонтированы поперечjttie оси со свободно установленными на них коническими шестерн ми, зацепленными с зубчатыми венцами шкивов, причем последние выполнены с возможностью вращени относительно упом нутого вала.To achieve this goal, the balancing devices are made in the form of bevel gear rims, rigidly mounted on the end faces of the pulleys facing each other coaxially with them, and transverse axes with freely mounted bevel gears meshed with the gear rims of the pulleys are fixed on the shaft, the latter made rotatable with respect to said shaft.

Claims

FA: 1 shows cable installation, general view; in fig. 2 - drive shaft with a friction pulley and balancing devices. 3S The multi-gang lifting installation includes an actuator 1 (Fig. 1) on a drive shaft 2 of which the pulleys of friction 3, which are bent by ropes 4 attached directly to the lifting vessel 5, are mounted with rotation. On the drive shaft 2 there are transverse axes 6 on which - Gears 7, which are engaged with the toothed conical rims of 8 pulleys of the firing 3. The lifting installation works as follows. When the drive shaft 1 rotates the drive shaft 2, rotation through the transverse axles 6 and bevel gears 7 is transmitted to the toothed bevel rim 8 and, consequently, to the chippers of the firing 3. The mixing of the vessel 5 is carried out due to the presence of friction forces between the pulleys 3 and the ropes 4. In the event of a difference in tension in two adjacent ropes 4, the difference in torques created by the corresponding pins 3 results in their relative rotation and the greater the difference in tension. Due to the rotation of the pulleys 3 relative to the area of the aruga, there is a partial displacement of the ropes 4, one of which increases the tension in the rope towards the deco side and the other towards increasing it. Thus, tension is built up in the ropes. When rotating the drive shaft 2 in the reverse direction, the operation of the lifting unit and the balancing device is similar. In a lifting installation, the snatching tension leveling stroke is determined by 5 collars of the pulleys relative to each other and thus is practically unlimited. The location of the balancing device directly on the drive shaft of the lifting mask significantly improves the operating conditions of the suspension and increases its reliability. Since the screws are made with the possibility of separate rotation from each other, the process of weighting and adjustment of their lengths is simplified. Claims of the invention: A multi-channel lifting installation comprising pulleys mounted on the drive shaft and the pulleys around which the ropes are suspended and vessels and balancing devices, which, in order to increase reliability and improve operating conditions, balancing devices are made shaped bevel gears, rigidly fixed on facing each other ends of the shchivs coaxially with them, and transverse axles are fixedly mounted on the shaft with freely mounted "" and conical gears, hooks Shmi Wendy toothed pulley, the latter being made rotatable relative to said shaft.
