Abstract

This invention relates to a lifting and transport equipment. The purpose of the invention is to expand the operational capabilities by ensuring that the force is controlled to clamp the load of various sizes. The lifting device includes two shoulders levers 1, at the ends of the upper arms of which sectors 2 are fixed, along the curvilinear surface of which the rollers 11 of the spacer rods 8 move, driving the levers 1 and causing a smooth increase in the clamping force. 1 il.

Description

The invention relates to lifting machinery, in particular, to load handling devices.

The aim of the invention is to expand the operational capabilities by providing control of the clamping of the load of different sizes.

The drawing shows a view of the type of load gripping device .. g

The load gripping device contains two symmetrically located double-arm levers 1 with sectors 2, articulated by means of brackets 3 to the frame 4, on which the vertical is attached - 5) the front 5 with a slider 6, forming a four-contact mechanism 7. fixing the two-arm positions. On the slider 6 fixed spacer telescopic rods 8., limiters 20 9 and safety nets 10,

Two shoulders levers 1 welded from the pipe part of the bottom and sheet metal - top. In the pipe parts, bolts with the possibility of 25 vertically moving the rod 1I are located and fastened to which the clamping jaws I2, the length of which corresponds to the size of the cargo package, are attached with bolts through the flanges. DOR At the ends of the upper arms of the two shoulders 1 the hinged sectors 2 with a curved working surface and holes for adjusting the angle of inclination to the vertical are strengthened. The welded hinge brackets 3 are connected at one end to the two-arm levers 1, and the other, cylindrical, is mounted with the possibility of moving into the frame 4. On the frame 4, the Q vertical upright 5 dd of the slider 6 is reinforced, which are included in the four-stroke mechanism 7 for fixing the positions of the double-arm levers 1. In the upper part of the upright 5, the limiters 9 limiting the movement of the slider are rigidly fixed 6, which are segments of chains, the second end of which is fixed on the inner surface of double-arm levers I. In the horizontal CQ of the slider 6 with the possibility of extension, bolts are attached with bolts 8., on the axes of which are mounted rollers. On the slider 6 strengthened suspension.

 The device works as follows. . ,

To adjust the load gripping device to a certain size of the cargo by maximally extending the brackets 3 from frame 4 and the rods 8 from the slider 6, the lower arms of the double-shouldered arms 1 are moved apart. With the help of a lifting device, the load gripping device is hung on the hook, , slide the brackets 3 into the frame 4 and the rods 8 into the slider 6, reduce the lower arms of the levers 1 to the load. Then, using a series of holes in sectors 2, the latter are installed on the upper arms of levers 1 with an angle of inclination to the vertical (/ e) equal to 10-20. Then the device, applying a force to the suspension, moves the slider 6 up, the rollers move along the curved surface of the sectors 2 and pushing the upper shoulders of the levers I, whose lower shoulders, shifting, clamp the load. The locking mechanism 7 locks the two shoulders levers 1 in the working position. The lifting machine lifts the load handler with a load. When lowering the load, the slider 6 is lowered along the pillar 5, due to the imbalance of the arms of the levers 1, the upper shoulders move and the lower arms move apart, freeing the brick package. The levers 1 are locked in the open position by the locking mechanism 7.

Claims (1)

Claims: Load-carrying device comprising a frame, two shoulders pivotally attached to it, upper arms of which are inclined to the vertical axis of symmetry, and clamping jaws are attached to the lower arms, a four-stroke locking mechanism including a vertical rack fixed on the frame and a slide mounted on the slide and spaced rods located in the horizontal plane for interaction with the upper arms of the double-arm levers and the suspension for the hoist of the hoisting machine, characterized in that spherical capabilities by controlling the force of clamping a load of various sizes, it is provided with sectors located in parallel vertical planes facing 4A with their curvilinear end surfaces down and fixed pivotally at the ends of the upper shoulders of two shoulders 51595780 levers with the possibility of interaction of the planes of the upper shoulders of the double-arm ry- with the ends of the spacer rods and fixation; chagov, with spacer rods of their positions relative to the lateral non-telescopic.
