Abstract

Usage: with the method of loading long goods onto a vehicle), the loading time is shortened and a vehicle with increased productivity is used. The vehicle contains a portal frame 8 of the chassis, a tick grip 5 with a water jaw that is pivotally mounted to a traverse mounted with the possibility of vertical movement by the drive 7 of the portal frame 8. The traverse is equipped with load gripping slings 9 and a horizontal beam 12 with fingers, and tick the grippers 5 are made with grooves 10 for mounting the said fingers 11. The method of loading long loads onto the vehicle consists in lowering the yoke and the tongs, tongs ayut of load and raise the load on the grippers 5. In this case the cargo is further connected with means of handling slings crosspiece 9 and raise their goods while lowering the tongs 5 relative to the crosspiece gripping of the latter. 2 s.p. f-ly, 4 ill. fe

Description

Figl

The invention relates to the field of transport, in particular to the loading of long loads onto a vehicle.

A known method of loading long loads onto a vehicle is that before picking up the cargo with tongs, it is connected to the lifting device, lifted, the drive jaws of the tongs of the tongs lifted under it and the load lifted onto them. The specified method is applicable when loading pipes.

The disadvantage of this method is the difficulty of its implementation when capturing and loading building elements having a flat base (plates, blocks, elements of bridge structures, etc.). In order to be gripped by tick grippers, elevation of the building elements is necessary. After lifting the load and reducing the ticks, it is necessary to lower the load to the stop with the ticks, which requires additional time and additional labor to perform the indicated action.

There is a method of loading long loads onto a vehicle, which uses a magneto-mechanical gripper with electromagnets, which consists in lowering the yoke with tick grippers, capturing the load with them, including electromagnets that lock the grips from opening when moving cargo on them, and lift the load on the grips.

The disadvantage of this method is the need to raise the load in order to be gripped by tick grippers, which requires additional labor and time.

A known method of loading long loads onto a vehicle is that the load is lifted on slings, then the tongs clamped to the traverse pivotally attached to the beam are lowered, fixed, and the load is lifted on the grips.

The disadvantage of this method is that the operations of lifting and lowering the tongs are performed at the same time, which increases the time for loading the goods.

The closest in technical essence and the achieved result is a method of loading long loads onto a vehicle containing a portal chassis frame, a tongs with drive jaws, which are pivotally attached to a beam mounted with the possibility of vertical movement by the drive, which consists in lowering the beam and tick captures, they capture the load and lift the load on the captures.

The disadvantage of this method is that after lifting the load to reduce the ticks, the load is lowered to the stop with the grippers, which requires additional time and additional labor.

The aim of the invention is to reduce the loading time of long loads.

The goal is achieved in that

5, the load is additionally connected by load gripping slings to the traverse and they lift the load while lowering the tick grippers relative to the traverse until they grab the last one: the traverse is equipped with load gripping slings and a horizontal beam with fingers, and the tongs are made with grooves for installing the mentioned fingers in them . Figure 1 shows the transport

5 means for implementing a method for loading long loads; figure 2 is a section along aa in fig. 1, pipe grip; in Fig. 3 - a section along aa in Fig. 1, the rise of a building element with a winch; figure 4 is a section along aa on

0, figure 1, lowering the tick-borne grips when lifting the lifting beam with the building element.

Loading of long loads of cargo: - as follows. First t ha

5 1 with a trailer 2 runs over a long load - transported building element 3. Then lower the beam 4 with mite clamps 5, the drive jaws of which are pivotally attached to the beam

0 4, .and connect the building element 3 with the load gripping hooks 6. After this, the traverse 4 begins to be lifted by the lifting mechanisms 7, while simultaneously providing a relative displacement of the tongs 5 and the building element 3. Depending on the type of devices used, the relative displacement of the tongs 5 and building element 3 is carried out in various ways. AT

In the first case, it is possible to lift the building element 3 by means of winches mounted on the portal frame of the chassis 8 with fixed tongs 5, i.e. the lifting beam is

5 motionless. In another embodiment, the relative displacement of the building element 3 relative to the tongs 5 can be achieved by simultaneously lowering the tongs 5 relative to the beam 4 and lifting the latter together

with the building element 3 before being captured by its tongs 5. For this, the building element 3 with load gripping slings 9 is connected to the traverse 4, and the tongs 5 are made with grooves 10 and can freely move relative to the fingers 11 installed in the grooves 10 and fixed horizontally located beam 12 attached to the traverse 4. Tick tongs 5 have a control hydraulic cylinder 13, and the lifting traverse - rollers 14. interacting with vertical guides fixed to the portal frame of the chassis 8. It is also possible an option of providing relative displacement of tick-borne grips 5 and building element 3 by lifting them to various sizes. This can be achieved by using a differential mechanism.

In order to be able to grip the building element 3 with tongs 5, it is necessary that their relative displacement be not less than the thickness of the ends of the tongs 5 so that they can be placed under the building element 3. After the tongs 5 are placed under the building element 3 and the tongs 5 are brought together by the required value, the building element 3 is lifted on the hooks 5 to the vehicle.

The claimed technical solution is more efficient in comparison with the prototype, as it allows to reduce the time of loading cargo onto the vehicle for
