Description

one

This invention relates to roadless vehicles with mechanized loading and unloading of unit loads.

FIG. 1 shows a side view of the vehicle; FIG. 2 is a view A of FIG. ; in fig. 3 - settlement BB in FIG. 2; in fig. 4 is a section BB in FIG. 2; in fig. 5 is a section B-B in FIG. 2; in fig. 6 - vehicle hydraulic system.

The swivel frame 1 is hinged in the rear part with the chassis frame 2 by means of a bracket 3 with supporting rollers 4, and in the front part with two movable supports 5 made of rods of hydraulic cylinders for fixing the swing frame. The loading platform 6 is mounted on a pivoting frame 1 with the ability to move along it from the transport position to the loading position and is equipped with a safety device, by means of which it interacts with the pivoting frame when turning in the range from the transport position to the extreme upper one.

The winch 7 is mounted on the chassis frame 2 and is equipped with a flexible element 8 connecting it through blocks 9 and 10 of the rack 11 mounted behind the driver's cab of the vehicle on the chassis frame with 1 steering platform 6.

The device for fixing the pivot frame relative to the chassis frame during loading and unloading operations comprises a cylindrical retainer 13 placed in the hydraulic cylinder body 12. part of the hydraulic cylinders 15. The control lever, installed in the cab of the vehicle, by means of ropes 16, lever mechanisms 17, 18 and crank 19, rigidly connected with the cylinder eral retainer 13, ensures its rotation Hollow cylinders 15 connected to the tank 20, the shutoff valve 21 and the check valve 22, flexible piping 23.

The work is carried out as follows.

The winch 7 is turned on to wind the flexible element 8 onto the drum with the valve 21 closed 5 and the loading platform 6 is rotated together with the swing frame 1 (due to the interaction of the platform catch with the swing frame) relative to the ball 10

low pivot frame

with chassis frame. At the same time, the hydraulic cylinder rods with stops 5 are advanced and the cavity of the hydraulic cylinders 15 is filled with working fluid. The check valve 22 prevents the outflow of working fluid from the hydraulic cylinder 15, thereby fixing the stops 5 in the extended position. increase the reliability of fixation of the lugs 5 by the control lever by means of the ropes 8, the lever mechanisms 17, 18 and the crank 19 rotate the latch 13 to combine its cylindrical surface with a sample on the tail parts

stops 5 of the rods of hydraulic cylinders. When this happens, a rigid mechanical fixation of the lugs occurs. 5. The winch 7 is turned on to bend the flexible element 8, and skipping occurs.

cargo platform 6 with a rotary wound 1 until it stops with a rear cut into the ground.

Flexible element 8 is connected with a cargo by means of a first load and includes a winch 7 on its loading. At the same time, the load is pulled onto the load platform 6 and then the platform with the load rolls onto the swing frame 1. When the lever is fully rolled, the axis rotates the cylindrical clamp 13 until the grooves 5 align with the cylindrical surface of the stops 5, and the valve 21 opens the cavity of the hydraulic cylinders 15 seconds. tank 20. Include winch 7 on unwinding of the flexible element 8. In this case, the pivoting frame 1 together with the loaded platform 6 rotates into the transport polo. The stops, the stops 5 move in, into the hydraulic cylinders 15, Si, the working fluid flows into the tank 20.

The cargo is unloaded in the same sequence.
