Abstract

The invention relates to lifting devices mounted on a loader, and can be used for the handling of cylindrical loads with a central opening, in particular packages of automobile tires in warehouses and covered wagons. The purpose of the invention is to expand the functionality by ensuring the orientation of the pins relative to an arbitrarily laid load. Pin grip to the loader contains a frame 1, hung on the plate of the loader. The frame 1 is fixed to the rotation mechanism, made, for example, in the form of a block of power cylinders 3 with the rod-rails 4, interacting with a gearbox (L 05 with Yu Figure 1

The invention relates to lifting devices mounted on a loader, and can be used for the handling of cylindrical loads with a central opening, in particular, packages of automobile tires in warehouses and covered wagons.

The purpose of the invention is to expand the functional possibilities by ensuring the orientation of the pins relative to an arbitrarily laid load.

FIG. 1 shows the pin hook, front view, of FIG. 2 is the same side view} in FIG. 3 - the position of the grip before taking an arbitrarily laid load (orientation of the pins) J in FIG. 4 - the position of the grip during the transportation of cargo in the car in FIG. 5 shows the position of the grip when taking the load from the upper tier in the car in FIG. 6 - the position of the grip when installing cargo in the racks.

The pin hook to the loader contains frame 1, fitted with brackets 2 for attachment to the loader plate. The frame 1 is fixed to the rotation mechanism, made in the form of a block

4, interacting with the gear wheel 5, the axis 6 of which is mounted in the support 7 fixed to the frame 1. The first lever 8 is rigidly connected to the wheel 5, the second lever 9 is hinged at the free end of the second lever 9. The latter is equipped with a turning drive that made in the form of a cylinder 10, the body of which zakreprychagov 8 and 9 in one line: in the initial position, they are located at an acute angle. The pins 9 and 12 are placed on the lever 9, the lever 9 being installed on the same axis as the pin 11, and the pin 12 can be made permutable along the length of the lever 9, in which holes 13 are provided for this, depending on the diameter of the load (tire) , 1 з.п, ф-л, 6 Il.

flax on the lever 9, and the rod on the lever B, full stroke of the cylinder 10 provides the location of the levers 8 and 9 in one line, in the initial position they are located at an acute angle. The pins 9 and 12 are placed on the lever 9, and the lever 9 is mounted on the same axis as the pin 11, and the pin 12 can be made permutable along the length of the lever 9, which has holes 13 for this, depending on the diameter of the load 14. Control gripping is done from a conventional two-piece loader valve.

Pin capture to the loader works as follows.

In the initial position for working in covered wagons, the lever 9 is mounted horizontally. Depending on the diameter of the tires 14, the position of the pin 12 is adjusted. A loader with a grab, brought into position, moves up to the tire stack and seizes them. Since at any arbitrary arrangement of tires of the same size the center distance of two adjacent tires is equal to their diameter, to capture the load 14 by driving the movement of the levers 8 and 9, the position of the pins 12 relative to the central openings of the tires 14 is adjusted.

In order to take (or stack) tires 14 from the top floor of the carriage, the levers 8 and 9 are rotated to the upper position (Fig. 5). The loader with the cargo is sent to the place of storage of the cargo,

To facilitate the maneuverability of the loader with cargo, the lever 9 is rotated at an angle of 45 ° to the horizon. This reduces the size of the cargo 14 in width, which is especially important for free passage in the doorway of the car while working with a cargo of large diameter (Fig. 4).

To install the tires 14 in the racks (Fig. 6), the levers 8 and 9 are set by the drive in a horizontal position. Formula of invention
