Abstract

to the application for a utility model “Loading and unloading device of a vehicle”.

The solution relates to handling devices mounted on vehicles.

It is proposed to install a channel on horizontal racks of the platform by means of couplings with pendants, along the guides of which a carriage is moving, carrying a block mechanism for lifting the load.

This ensures the movement of cargo in all directions.

Description

The solution relates to loading and unloading devices installed on vehicles: closed and open bodies and platforms of trucks and trailers, transport containers, removable onboard platforms, etc.

A device is known for loading and unloading vehicles or containers (US Pat. RF No. 39051, B60P 1/00, publ. 2003.09.10). The device has a platform with a loading and unloading mechanism, a robot that transfers goods to a telescopic conveyor.

This device is, in fact, a mechanical arm, which is driven into the cargo space on a trolley (closed body, platform, transport container), occupying it. The conveyor also occupies cargo space.

As a prototype, a device for self-loading-self-unloading of a vehicle was adopted (ed. Certificate of the USSR No. 1735084, B60P 1/00 publ. 05.23.1992). The device comprises vertical racks mounted on the platform with horizontal rails, means for moving cargo in the form of a trolley built into the platform and moved along it, and means for capturing cargo in the form of T-shaped elements hinged on the frame with the possibility of interaction with the container strapping.

However, this device is intended only for transporting containers, i.e. bulky goods, mainly in the horizontal direction. The trolley occupies the cargo space of the body, it must always be carried along with the platform.

These shortcomings are eliminated by the proposed solution.

The task to be solved is the creation of an easily mounted and dismountable device for loading and unloading operations on a car platform.

The technical result is the mobility of the installation, the liberation of the workspace.

This technical result is achieved by the fact that in the loading and unloading device of the vehicle, containing vertical racks with horizontal rungs mounted on the platform, means for moving and gripping the cargo, the latter is made in the form of a channel installed by means of suspensions

on couplings on horizontal rails of the racks with the possibility of moving along them across the platform and changing the overhang of the channel along the platform, and in the channel guides on the rolling elements there is a carriage carrying a block mechanism consisting of a block, a winch with a reel and a cable, a lifting hook a block to the carriage and a sling hook to the winch body through thrust bearings and forks; the cable of the block mechanism is thrown through the block at the carriage and fixed to the bracket mounted on the winch body, to which the sling hook is also attached.

The implementation of the means of moving the cargo in the form of a channel with a carriage and couplings movable perpendicular to the movement of the channel and the carriage ensures the movement of cargo to any point on the platform. The block mechanism makes it easy to lift a load of significant weight (up to 0.5 t) and dimensions. The proposed loading and unloading device is shown in the drawings: in Fig. 1 is a general view, in Fig. 2 is a side view, in Fig. 3 is a carriage with rolling elements and a block suspension on a carriage.

The device comprises a platform 1 (possibly with sides and an awning) with vertical struts 2 and horizontal rungs 3, which can be removable. The cargo transfer means consists of a channel 4, fixed by means of couplings 5 on the crossbars 3 on suspensions 6 (for example, L-shaped), attached to the couplings 5.

The couplings 5 are movable along the crossbars 3 across the platform, and the channel 4 can move (manually) along the suspensions 6 along the platform 1. In the guides of the channel 4 there is a carriage 7 on the rolling elements (tapered rollers) 8. There are studs 9 on the channel that limit the movement of the carriage 7 and channel 4. The carriage 7 carries a block mechanism for lifting the load, consisting of a block 10 mounted on the carriage 7 body through a fork 11 and a thrust bearing 12, a coil 13 with a cable 14 thrown over the block 10 of the carriage 7 and fixed to the bracket 15, reinforced on the winch housing 16 and 17 of the lifting hook, also attached to the winch housing by means of a plug and a support bearing (as above, positions 11 and 12). For rigidity of the structure of the uprights 2 they are fastened with stiffeners 18. In the lower part of the uprights 2 are reinforced with heels 19, and the fastening of the uprights 2 is carried out from the bottom of the platform 1 by plates 20 and pins 21. The device is operated as follows.

To carry out work using, for example, a GAZELLE car, the device is mounted on the crossbars of 3 racks 2. The channel 4 and the carriage 7 are installed in the desired position, manually moving them to the position from where to load the goods. Through the block 10, located on the carriage 7, the cable 14 is thrown from the coil 13 of the winch 16 and the cable 14 is hooked to the bracket 15. The load is suspended on the lifting hook 17, and lifted by a manual winch 16 to the desired height. Manually move the carriage 7 along the channel 4 inside the body. At the same time, the channel 4 acts as an arrow of the lifting mechanism. Depending on the required location of the load on the platform 1, the couplings 5 are moved to the right or left, thus compactly stacking the load.

Fastening by a fork 11 and a bearing 12 ensures the rotation of the load. For unloading, the actions are carried out in the reverse order. The proposed device was tested under industrial conditions during loading and unloading of various cargoes (box-shaped, flat, tubular, short and long logs, etc.), which fully confirmed its industrial applicability.

The weight of the device is about 150 kg. One person can handle the job, as not much physical effort is required. This ensures safety, as loading and unloading is carried out not from the side, but from the rear side, the stability of the vehicle is not violated, the loads are rationally distributed.
