Description

The invention relates to the field of hoisting-and-transport devices and can be used to lift loads that exceed the rated load capacity of the lift cab.

The closest technical solution of the known ones is a lift containing 1ka | bina and opposite weight, equipped with vertical guides and connected to each other by means of ropes, enveloping a trailing driver, coupled by means of a coupling to a gearbox of the winch 1.

The disadvantage of this device is the impossibility of lifting the load, disturbing the nominal capacity.

The aim of the invention is the depletion of the ability to lift a load exceeding the carrying capacity of the cabin.

This is achieved in that the clutch is made with an axially movable loule coupling, parallel to the output shaft of the gearbox there is a drum, the shaft of which is connected to the OUTPUT shaft of the gearbox by means of a gear drive, the gear which is connected to the movable coupling half, and an additional gear provided with at the free end of the cargo hook.

The cabin roof is made with a hole through which the additional traction unit is passed, and in the lower part of the cabin there are straps fixing the load.

The drawing is punished. The proposed lift, a general view.

The ram contains a cab / and a counterweight 2, suspended on a traction device 3. The envelope is a traction head 4. The shaft of the pulley 4 is connected to the shawl 6 of the gearbox 7 of the winch 8 by a clutch coupling 9 having axially half coupling) 0. Parallel to the axis of the pulley 4, a drum 1 is mounted, the shaft 12 of which is mounted in the bearing supports 13 and connected to the gearbox shaft 6 of the gearbox 7 by a gear drive with the wheel 14 and gear 15, which is rigidly connected to the coupling half 10. On the drum 1 is wound a traction body 16, for example, a rope, the free end of which chmeet hook 17.

In the cabin / there are extensions 18 for securing the load 19 exceeding the nominal, and in the roof of the cabin there is a hole for the passage 17.

Works lift as follows.

When transport; 1rovke nominal load lift works in the usual way. Cab 1 with cargo located on the floor.

moved by a winch from 1katumanation1 lUKi-moM, and the shaft 5 is connected to the shaft 6 of the gearbox with the HELP of the coupling 9, sixth. pn / 5 At this time it is disengaged, which ensures the detachment of the drum // from the gearbox 7. When transporting the load is unnecessary, I will also cut the I1 , its nominal, clutch (base) clutch), disconnect - traction sheave 4 from gearbox 7 and traction presenter 4 becomes a conventional unit.

The gear wheel / 5 engages with the wheel 14, the endless drum / //. Connection with the gearbox leyedkn. In this way, the same winch itself, and the hoist is already used in conjunction with a ba.raban instead of caiover: h) W | Knva. To the traction body 16: when the NOMO1CI hook / 7 lodges the load 19, which has been fastened in the cab by stretching 18, and prevents it from swaying when it is moving. In this case, the force in the traction body 16 is equal to the difference between the sum of the weights D) usa J9 and the cab / minus the weight of the counterweight 2. The choice of the ineffectual Number depends on the ratio of the load on the traction body 16 to the difference of the weights of the counterweight and; In the same way, the speed of the cab moves relative to the rated speed of the lift.

In this way, the design of the lift makes it possible to transport both cargo and, if necessary, cargo, not only nominal, which is achieved without a significant change in conventional i-lifts, without an increase in stiffness: kaoins and all butt-fit settings. winch), calculated for the terminal load lifter. five
