Description

(54) GRIPPING CAPTURE

The invention relates to a lifting transport machinery, in particular to hydraulic grab mechanisms for the processing of timber cargo.

According to the main author. St. No. 656951 is a grab grab containing a frame with guides and a groove in the middle part 1.

They are mounted in directions Yush. They are movable from the hydraulic cylinders of the carriage, each of which is pivotally attached with several gripping two shoulders, equipped with rollers, and stops installed in the middle part of the frame, interacting with the non-working shoulders of the double shoulders.

However, this grapple does not capture single logs.

In order to ensure that the grab holds single logs, the frame with the guides is made of two parts interconnected overlapping and offset relative to each other beyond the axis of symmetry of the grip.

FIG. 1 shows the proposed grab grab; in fig. 2 - the same, top view.

5 wider right half-frames 5. Each half-frame has trough-shaped guides of channel type.

The left 1 and right 2 gripping levers are also made of different widths, and the upper parts are equipped with a cantilevered 10 ni rollers 6, which are placed in the direction of the left 4 and the right 5 semi-frames with the possibility of moving along them. Hydraulic cylinders (7) serve as the PryvShShSh chelyustsy, with one ends hingedly connected to the Yrfthyrchrcfyrtojtojyram, and to the other (gtgperechischinami jaws.

Left 4 and right 5 half-frames are displaced relative to each other by an amount that ensures rolling of the rollers of the left gripping lever 1 by the rollers of the right

20 gripping lever 2 with fully extended rods of the hydraulic cylinders 7. This ensures the overlapping of the teeth of the jaws relative to each other in their reduced position.

Claims (1)

785177 The capture operation is carried out as follows. Prior to bringing the load to the place where the goods are located, the rods of the hydraulic cylinders 7 are advanced. At the same time, rollers 6, rolling over guides of half-frames 4 and 5, disengage gripping levers 1 and 2 and raise them to extreme position I. After pointing the gripper lowers, rods of hydraulic cylinders 7 are pulled and gripping levers move along the guides to each other . At the initial moment of lowering the gripping levers, a rotationally accessible movement occurs from the ends to position II, ensuring the introduction of the gripping levers into the scooped load. By their subsequent movement, they scoop up pieces of wood located on a large area, compress them and form them in a pack. This process occurs when working with weights such as logging wastes, softwood feet, etc. When loading thin logs, thin logs from thinning, and other similar loads, not only is bundle formation, but also reliable retention of separate thin-bore wood: by rolling the rollers of the left and right jaws behind each other and moving the jaws to position III, ensuring the overlapping of their teeth. Claims of invention St. No. 656951, characterized in that, in order to ensure the capture of single logs, the frame with the guides is made of two parts interconnected by an overlap and cMet relative to each other on the axis of symmetry of the grip.
