Description

This invention relates to a rolling stock of specialized road transport.

A cargo handling device on a camper is known, advantageously for joint cargoes, comprising a trolley movable along guides along the body driven by the power box of the truck.

However, such devices do not provide a lot of light-weight bodywork and are inconvenient in ecological operation.

The purpose of the invention is to provide a lot of light-weight mechanized loading of gravity loads over (the whole area of the floor of the body and increase of the ease of use.

This is achieved by the fact that, in the proposed device, the trolley drive is provided with two winches, and the trolley is made with a cantilever part carrying a movable carriage and a traverse that is led to the carriage through a polyspast with a pair of ropes, one end fixed on one of the winches, and the other In this case, another pair of ropes is connected to the second winch.

FIG. 1 shows the described device, a general view: in FIG. 2-unit trolley with a carriage; in fig. 3-cart with carriage, plan view; in fig. 4 is a scheme for fastening the ropes to the traverse and winding deflecting rollers with them; in fig. 5, side view; in fig. 6-position of the ropes on the front wall of the van; in fig. 7- drive device; in fig. 8-extreme upper position of the traverse; in fig. 9-move containers or pallets in a locked position.

The device comprises a cantilever carriage consisting of frame 1, traveling wheels 2 and roLIK01B 3 located along the edges of the frame, a carriage consisting of frame 4, traveling wheels 5 and rollers 6 located along the edge of the frame of the carriage. The carriage frame is provided with stops 7 and 8. The traverse to which the load is attached consists of a beam 9 supporting

rollers 10 and hooks 11.

The mechanism for lifting and moving cargo inside the van consists of two winches 12 and 13 and is driven by the power box of the van. On camper

envelope rollers 14 are installed. Two ropes 15 and 16 of the winch 12 and ropes 17 and 18 of the winch 13 are wound on the drums of the winches. Ropes 15 and 16, rounding the rollers 14, 3, 6, 10, are stored in traverse in the form of a chain hoist. Ropes 17 and 18 are attached to the carriage.

Brake 19 is put on the drum of the winch 13, and on both drums there are mounted gear 20 and 21, which can be interlocked by means of the clutch 22. The drive for rotating the drums can be

fully hydraulically by means of a hydraulic motor 23 connected to the drum shaft of the winch 12, or mechanically using a cardan shaft connecting the drum of the winch 12 to the power take-off of the car. For moving the carriage inside the body, guides 24 are installed, supported by the uprights 25.

The handling device operates as follows.

For lifting or pulling the traverse with a load, the drums of both winches are separated, i.e., the coupling of the coupling 22 is disengaged from the shchestryi 20 and 21.

In this case, when the drum of the winch 12 is reversed, the load rises or the OR goes down. At the same time, the carriage remains stationary and is kept from shifting to the left under the influence of the weight of the load with the help of ropes 17 and 18 of the braked drum of the winch 13.

To enable the horizontal movement of the yoke with a load along the body, the clutch 22 is brought into engagement with the gears 20 and 21 and connects both drums for joint rotation. As a result, the synchronous speed of the tO1s of both winches is ensured. When moving to the left, the pulling body is a winch 12 or the weight of the load, and the winch 13 at this time provides the synchronous feeding of the ropes 17 and 18. When moving the yoke, the pulling power is the winch 13, and the winch 12 provides the simultaneous feeding of the ropes 15 and 16 The bice ropes of both winches are automatically tensioned with the weight of the traverse with the load.
