Description

1136

The invention relates to a lifting machinery, in particular 1 gripping devices.

The aim of the invention is to increase reliability in operation.

FIG. 1 shows the gripping device; in fig. 2 - an assembly unit for cams and blocks on the frame.

The gripping device comprises a frame 1 and two groups of vertical fingers 2, which clamp and hold the weights. The fingers 2 pass through the holes in the gripping bodies 3 fixed on the lower ends of the vertical shafts 4, on the upper ends of which the cams 5 are fixed with grooves on the end surfaces. The cams 5 are connected in pairs by cables 6, the envelopes 7 below, mounted vertically on frame 1, and block 8 mounted vertically on rod 9, rod 9 passes through a vertical central hole in cross member 10 and spring 11 through which rod 9 rests on cross member 10 The crossbar .10 is pivotally fixed on the rods of the power cylinders 12, the housings of which are fixed to the frame 1. The springs 13 provide for the return of the fingers 2 to the initial position, are fixed at one end to the cams 5, and to the other on the longitudinal beams of the frame 1. On the frame 1 also fixed enes on the rotary cylinder 14, the gripping levers 15. The frame 1 is hinged to the cross member 16.

The gripping device operates as follows.

At the beginning of work, fingers 2 in the initial position are turned counterclockwise up to the stop and the gripping levers 15 are raised. Before seizing items, the device is lowered on top of them.

After the gripping device is lowered, the products are pressurized to the power cylinders 12. The cross bar 10 rises, the block 8 t is no cables 6, which act on the cams 5, the shafts 4, and the fingers 2 turn clockwise. When the movement stops, when the fingers 2 are clamped, the springs 11 start to compress. To the cat; In the end, all the products are squeezed with fingers 2. On the window

With the clamp, the gripper rises along with the clamped articles.

g When lowering products, the power cylinders 12 retracted their rods, the cross member 10 is lowered, and the springs 13. return the gripping bodies 3 to its original position.

In some cases, when a group of products is captured, the products are first captured by fingers 2, and then the gripping levers 15,

Invention Formula

A gripping device containing a traverse attached to a lifting mechanism, a frame connected with it by hinges, gripping members with moving vertical fingers, pivotally fixed on the frame and connected by a horizontal shaft drive spring-loaded gripping levers, force cylinders of gripping the gripping members and a transmission mechanism motions to the latter from their power cylinders, including vertically mounted on transverse beams of the frame, shafts at the lower ends of which the gripping bodies are rigidly fixed, lichayuschees the fact that, for the purpose of reliable povsh1eni

In operation, the mechanism for transferring movement to the gripping bodies from their power cylinders further includes rigidly mounted on the upper ends of the shafts and cams with grooves on the end surfaces, spring-loaded relative to the longitudinal beams of the frame, and articulated to the rods of the vertically mounted power cylinders with central vertical holes MI located in them and spring-loaded relative to the cross member of the rod and cable-block systems, one of the blocks of each of which is fixed vertically on the bottom m late

rod, and the other two - vertically on the longitudinal beams of the frame, while the cable is located in the grooves oppositely placed cams, rigidly fixed to them with their ends and alternately rounds the blocks located on the frame and rod.

Claims (1)

Claim A gripping device comprising a traverse connected to the load-lifting mechanism, a frame connected to it by swivel links, vertical gripping bodies passing through a vertical central hole in the cross member 10 and a spring 11 through which the rod 9 rests on the cross member 10. The cross member .10 is pivotally mounted on the rods power cylinders 12, the cases of which are fixed on the frame 1. The springs 13 ensure the return of the fingers 2 to their original position, fixed at one end on the cams 5, and the other on the longitudinal beams of the frame 1. On the gripping levers 15 are also fixed to the frame 1, which are rotated from the power cylinder 14. The frame 1 is pivotally attached to the traverse 16. The gripping device operates as follows. When starting work, the fingers 2 in the initial position are turned counterclockwise to the stop and the gripping arms 15 are raised. Before capturing products, the device is lowered onto them from above. After lowering the gripping device, pressure is applied to the products in the power cylinders 12. The cross member 10 rises, block 8 pulls the cables 6, which act on the cams 5, the shafts 4, and the fingers 2 are rotated clockwise. When their movement stops, when the fingers 2 clamped the product, springs 11 begin to compress. fingers, pivotally mounted on the frame and connected by a horizontal shaft, spring-loaded drive gripping levers, grippers for moving the gripper bodies and a mechanism for transmitting movement to the latter from their hoisting cylinders, including shafts vertically mounted on the transverse beams of the frame, the gripping bodies are rigidly fixed to their lower ends characterized in that, in order to increase reliability ~ ^<: March ₅ NOSTA in operation, motion transmission mechanism for the gripping organs from their cylinders rigidly fasten further comprises Cams with grooves on the end surfaces located at the upper ends of the shafts and spring-loaded relative to the longitudinal beams of the frame, a cross-member hinged with the rods of vertically mounted power cylinders with central vertical holes, located in them and spring-loaded relative to the cross-member of the rod and cable-block systems, one of the blocks of each from which it is mounted vertically on the lower end of the rod, and the other two vertically on the longitudinal beams of the frame, while the cable is located in the grooves opposite to nnym cam is rigidly fixed to them at their ends and ponechnom a result, all the items turn out the next 55 encircles blocks located binding clamped fingers 2. okon- HA frame and boom.
