Description

"one

The invention relates to loading and unloading devices, in particular, for unloading a package: steel sheets, for example, from the body of a UUiUbl,

The purpose of the invention is to improve the efficiency and reliability of operation of the device.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. 15 in FIG. 3 is a section BB in FIG. 2; in fig. 4 - the mechanism for moving cargo along ball bearings.

The device works in the following way.

A vehicle with a load of 28, for example, with a sheet of steel sheet, and open-M1 sides, is installed parallel to the lifting platform 3 in close proximity to it, the platform 3 is in the initial position, and the forks are pulled inwards. At the beginning of the unloading, the nlatform 3 with the help of the hydraulic cylinder 5 and the levers 4 is pushed until the level of the lower surface of the fork reaches the level of the car body. The drive of the chain mechanism 27 is turned on and the forks roll in on the wheels 17 into the lumen between the supports of the pallet 29, a load is placed on the JcoTopoM, then with the help of the hydraulic cylinder 10 and the lever 11 pivotally connected by a hydraulic cylinder rod, the upper supporting profile of the fork will move until the until the load is detached from the noddon and doesn’t have 15 forks on the hooks.

When Iodiem upper support profile and turn triangular rspsh

The 16 wheels are removed and the bottom frame 8 lies on the floor of the car body. As soon as the load is on the ball bearings, the mechanism for moving the load on the ball bearings turns on, at this time the carriage 18 with the pusher 21 in horizontal polishing moves from the lifting platform 3 to the end of the forks, moving 1 each, guiding 19 and passing under the load. Then the carriage 18 is stopped, the pusher 21 is rotated around the axis 20 and rests on the load. The carriage 18 moves in the opposite direction and the pusher 21 moves the load along the ball bearings .15 of the upper frame 9 to the lift

platform 3, from where the cargo is removed, and the cargo from platform 3 can be removed from either side, since it lies on the ball oior 15 of the platform. After the truck is unloaded, the hydraulic cylinder is turned on, with the help of which the upper frame 9 slides down through the lever 1.1, the triangular levers turn, the wheels 17 extend and stand on the floor of the body. Turn on the chain mechanism 27, forks clean inside the plate 3, while the wheels

17kTs but the floor of the car body without load.
