Description

The invention relates to lifting machinery and can be used to reload shoe pallets with fruit and vegetable products.

A fork is known to the loader, which contains two extreme movable along a horizontal guide and one non-adjustable middle forks and drive 1.

A disadvantage of the known capture is its low productivity.

The aim of the invention is to increase productivity.

The goal is achieved by the fact that in the gripper to the loader, which contains two extreme horizontal guides and one stationary middle pitchfork and drive, the latter contains two double-acting hydraulic cylinders located in the horizontal guide and two three-position distributors connected via pipelines to the hydraulic cylinders, respectively at the same time, the working part of each fork has an M-shaped contour, while the middle fixed forks have a length of the working part greater than the extreme movable forks.

FIG. 1 shows a schematic diagram of the proposed load gripping with an indication of possible options for the movement of forks, the general view; in fig. 2 — load grip, grasping two rows of sliding pallets, side view; in fig. 3 - fork cell, side view; in fig. 4 - execution of a load gripper with an odd (three) number of forks, grabs, general view.

The fork fork to the loader consists of a base 1, which is visited by a conventional (without lateral displacement) loader carriage. The base 1 has horizontal longitudinal guides 2 along which the forks with the help of the two-acting hydraulic cylinders 3 arranged in it can move the forks 4 connected directly to the hydraulic cylinders 5. Each cylinder is connected via pipelines 6 to a separate three-way valve 7 or to a separate hydraulic section of the block valve. The control knob 8 of the three-way control valve 7, for changing the direction of fluid flow, has three positions: left, right and neutral. This almost separate hydraulic drive of each extreme fork pickup provides, through various combinations of the direction of flow of the working fluid by pipeline 6, the following movements: and the right pickup - to the left; in the right pickup - right; with the left pickup - right; d left grab - to the left; both pods are simultaneously toward the middle (shifted); f both pickups are simultaneously moved apart; g both grabs at the same time to the left; h both grabs are simultaneously to the right.

Although there are an odd number (three) of fork pickups, the middle pickup 9 is stationary and is attached to the bottom of the load grab 1, and for convenience of loading into the pan 10, its working part has a slightly larger length than the extreme pickups. In this case, the working part of each fork has an M-shaped contour.

0 Fork tacks 4 and 9 are made monolithic, i.e., from one steel sheet, and their upper working surface slopes towards the ends of the forks. To facilitate fit, there are notches outside the specified cross sections. Such a design of the fork pickup enables the working part to be made sufficiently thin and, at the same time, durable to grip and lift two rows of sliding pallets.

The overloading of the slip pallets with the help of the proposed load gripping is done as follows.

To the pallets 10, installed, for example, on the car, pulls up the truck with a load capture. The driver, controlled by the handles 8 of the hydraulic distributor 7, using various options for the movement of the fork arms 4, sets them in the most convenient position for insertion into the openings of the pallets.

Forklift forward forklift

0 grabs are inserted into the pallet apertures. Depending on the performance of the load gripper, four (two rows) or three slider boards 1a are simultaneously captured and raised. After lifting the pallets, the driver uses fork motion options.

5 pickups, brings the group of pallets into an ordered state, since in a car they could stand with gaps and displacements relative to each other. A group of pallets is then transported, for example, to a stacker or conveyor belt.

° When stacked, for accurate, accurate and reliable installation of pallets, the driver uses the appropriate options for the movements of the forks, along with the pallets. Options provided

5 movements also allow pallets to be placed in storage conveyors. After. installing pallets loader drives off, withdrawing fork hooks from openings. The cycle is then repeated many times. Similarly, slip pallets can overload

0 with and in other technological schemes, where you can use the proposed load gripper.

The use of the invention provides a significant increase in the productivity of the overloading of slider pallets with fruit and vegetable products, especially at fruit and vegetable bases, which is of great national and economic significance, since the reduction of

saves the number of people engaged in ethnologies, increases the safety of vegetables

have worked. The time of storing trans-fruits and fruits is reduced, which in total gives a significant tailoring tools under the reloading one-economic effect.
