Description

The invention relates to devices for transporting self-propelled vehicles, namely, supports for transporting the chassis of the trucks in the container.

A device and method for loading the chassis into a container "STANDARD" of General purpose (ISO 1496/1). The support on which the load is mounted is made in the form of sections mounted on roller bearings. Guides are fixed on the container floor along the entire length of the container. The method includes the following steps: dismantling the chassis into at least two parts - front and rear; dismantling the outer beam; and connecting the disassembled parts into one device with the possibility of moving into a container. Sections with cargo are pushed into the container along the laid guides, overcoming the rolling friction of the support rollers along the guides installed in the container (1).

The disadvantages of the known device and method of loading the chassis semi-trailer are material consumption, the complexity due to the need for laying guides in the container, as well as the presence of similar guides at the loading and unloading sections, the presence of special devices for securing the sections with cargo (screw clamps, nails, etc.), the need connection of disassembled parts into a single device, which significantly increases the cost of transporting the chassis.

The objective of the invention is:

1) reducing the cost of sea transportation of the chassis of the self-propelled machine by ensuring that the stand is pushed from the truck chassis from the loading ramp into the container without the use of additional guides;

2) improving the operational characteristics and expanding the functionality of a universal device for transporting the chassis of a self-propelled machine by ensuring the fixation of the chassis of a different base without mechanical means of attachment to a universal stand.

3) reducing the complexity of the process of installing the chassis on the stand.

The solution of the tasks is as follows.

A universal supply containing supports made according to the claimed invention in the form of two pairs of main runners, on which are fixed: front stops made in the form of protruding longitudinal beams with a support bevel, between which crossbars are installed, as well as rear V-shaped stops that form with front stops of the "bed"; back support in the form of triangular prisms formed by inclined racks. The triangular prisms of the rear support are fixed on the main runners and additional runners, which are mounted longitudinally from the two outer sides of the main runners, and are rigidly interconnected by cross members.

The method of loading the chassis of a self-propelled machine, for example, a loader on the inventive universal stand and transporting it to the container, includes two stages: the first stage is the installation and fixing of the bottom sheet of the front frame of the chassis of the loader in the "bed" of the stand, while the frame of the rear chassis frame balancer is mounted freely back support; the second stage is the transportation of the universal stand to the STANDART container by means of a pusher loader.

The invention is illustrated by the following drawings:

FIG. 2 is a general view of the universal stand when lowering the chassis onto the universal stand;

FIG. 5 is a side view of a universal stand with a chassis of a loader with a carrying capacity of 3 tons;

FIG. 6 is a side view of a universal stand with a chassis with a carrying capacity of 5 tons;

FIG. 7 - transportation of the universal stand from the chassis of the loader from the loading ramp to the container "STANDARD".

The universal stand comprises runners 1 connected in pairs with crossbars 2, on which are fixed: front stops 3 in the form of protruding longitudinal beams with a support bevel, between which rigidly mounted crossbars 4, rear V-shaped stops 5, rear support 6. Rear support 6 is made in the form of two triangular prisms formed by inclined racks 7, rigidly interconnected by crossbars 8 and fixed on the main runners 1 and additional runners 9 located on two outer sides of the main strips sieves 1 and rigidly connected to them by crossbars 10 (Fig. 1). Between the front stops 3 and the rear V-shaped stops 5 on the main runners 1 formed "beds" 11 (Fig. 2-4).

The method of loading the chassis of a self-propelled machine, such as a loader, on a stand using a universal stand for transporting a self-propelled machine is as follows.

First, the chassis of the loader is dismantled: axles with wheels, attachments, cab are removed. The bottom sheet 12 of the front frame 13 of the truck chassis is installed in the "bed" 11 - sections of the main runners between the front stops 3 and the rear stops 5 with a gap of 5-7 mm on each side. Fixing in the longitudinal and transverse directions of the front frame 13 of the chassis of the loader relative to the stand is carried out by the presence of rest friction (from the weight of the load) between the front frame 13 of the chassis and the main runners 1 on these "beds" 11 (Fig. 3). In this case, both side walls 14 of the front frame 13 of the chassis are located outside the runners 1 with a gap of 3-5 mm (Fig. 4).

The frame of the balancer 15 of the rear frame 16 of the chassis freely rests on the struts 7 of the support 6 (Fig. 5, 6). For loaders of different bases (2800-3130 mm), the lower part of the front frame 13 varies slightly. Thus, with an increase in the loader’s base, the chassis balancer frame 15 moves freely along the struts 7 of the support 6 (Fig. 6), which makes it possible to install at least two standard sizes on the universal stand of the chassis of self-propelled vehicles.

Transportation (pushing) the chassis of the loader on a universal stand in the container "STANDARD" is carried out by the second wheel loader as follows.

The pusher loader 17 through the arrow 18 and the stop 19 transfers the force to the rear frame 16 of the chassis (Fig. 7). Then, by pushing the front frame 13 against the front stops 3 (after choosing a gap of 5-7 mm), the movement is transmitted to the universal stand, which, overcoming sliding friction between the runners 1 and the plywood floor plywood of the container 20, is moved to the "STANDARD" container. The area of the runners 1 is designed in such a way that does not cause deformation of the puff plywood of the floor of the container 20 from the weight of the chassis. In the container 20, the chassis is fixed by tying the frames 13 and 16 of the chassis with textile fastening straps to the cargo eyes inside the container 20 (not shown in Fig.).

In this case, the additional clamping force from the tension of textile fastening belts together with the rest friction force from the load weight fixes the chassis on a universal device.

Pulling the truck chassis on a universal stand from the container 20 is carried out by the tractor. The tractor by means of a cable fixed to the rear towing eye (not shown in Fig.) Transmits the movement to the rear frame 16 of the chassis. The chassis by abutting the front frame 13 in the V-shaped stops 5 (after selecting a gap of 5-7 mm) transmits the movement to the universal stand and pulls it along from the container 20 to a conventional ramp. The cargo, together with the universal stand, can be transported by a conventional road train to the loader assembly site as cargo on flat supports.

Thus, the present invention allows to transport the chassis of self-propelled machines of different sizes in the container and solves the issue of loading and unloading the container "STANDARD" without the use of guides and without mechanical means of securing the load to the universal stand.
