Description

one

The invention relates to the field of hoisting equipment.

Known lifting and turning devices, such as a clamp grip, suspended on the tsryuke crane, on the tongs of which are fixed pressure plates. Electric motors, imitated in tongs, provide rotation of the pressure plates. The tongs are unclamped and compressed using hydraulic cylinders. Such devices are structurally complex, require pneumatic, hydraulic or electric drive and skilled labor, difficult to maintain.

The purpose of the invention is to simplify the design of the gripping device and to automate the processes of unclamping and compressing the pivot arms. This is achieved by the fact that in addition to the traverse of the gripping-turning device, two two-armed support posts are hinged together.

In order to ensure quick and smooth rotation of the load, the pressure packs of the proposed turner are equipped with return springs and restrictive stops. The axes of rotation of the pressure pads are displaced in the direction of turning towards a vertical axis passing through the axis of the suspension link.

FIG. 1 shows the proposed grabber in the initial position, front view; in fig. 2 - the same gripper-tilter at the seizure of cargo, front view; in fig. 3 - the same, side view; in fig. 4 - the same occupant with perekantovanny load, front view.

The gripper-turner contains the yoke 1, on the ends of which are fixed the axis 2 of the rotary levers 3 (see Fig. 2), and in the middle of it is the stand 4 of the locking mechanism 5. To the slider 6 of the locking mechanism the axle 7 is attached, on which the hinge is fixed suspension 8 and two ti gi 9. T gi other ends with the help of the axles 10 of the connector with pivoting levers. On the pivoting levers are hinged in the fingers 11 of the body 12 of the supports, in which the fingers of the 13 clamping pads rotate. these overlays. Two traversing two shoulders are attached to the traverse 1 on the wasps x 17 and the legs (18) are 18.

In the initial position, before receiving the load with a tilting device, mechanism 5 fixes the olecro 6, and through it the rods 9 and

pivoting levers 3 with lining 14 in the extended position (see Fig. 1). With the help of a crane, the tilting device is lowered in order to grip and perekantovat the load from the vertical to the horizontal position, before the contacting pillars 18 touch the end of the load. Under the action of the weight of the slider 6 with axes 7, 10 and t 9 and its own weight, the pivot levers are dispersed until the mechanism 5, which unlocks the initial position, is triggered.

When the crane is raised, the swivel arms with 3 pads 14 grip the load; the force of the load is determined by its weight. Upon further lifting of the hook, the load, together with the linings, is smoothly turned over in the bearings of the housing 12, expanding the spring 15. The curvature is turned to the horizontal position, at which the stops 16 come into contact with the pivoting arms. At the beginning of the canting, the two shoulders of the uprights 18 are rotated on the axes 17, carried along by the load, then get out of the engagement with the latter and occupy the initial position (see Fig. 4). The tipping of the load when it is lifted spontaneously, since the axes of the fingers 13 of the pressure pads are below the weight of the load, for example, by the value τ and are displaced horizontally in the direction of turning towards the vertical axis passing through the axis of the suspension link 8, for example, by .

When the krap hook is further lowered, the swivel arms 3 are consumed by the vehicle, the gripper is tipped with two shoulder arms 18 and rests against the re-curtailed weight, the pressure pads 14 are returned to their original position by means of springs 15, the mechanism 5 is fixed

the swivel arms in the diluted state and the gripper are ready to accept the new load (see Fig. 1).

When seizing and transporting cargo without the need for tilting, the cargo is captured slightly above the center of gravity, and the two arms are shortened.
