 The invention relates to a lifting (conveying technique, in particular to the tong tongs.

The aim of the invention is to simplify the design.

The drawing shows a clamp grip, a general view.

Tick-borne grip consists of two levers 1, having a common horizontal axis 2, interconnected by a strap 3 with a Z-shaped groove 4, a spring-loaded spring 5, horizontally | Talny axis 6, in contact with a Z-shaped | different groove 4, t g 7 and 8, connecting the suspension 9 with two-arm levers | 1 and with the common axis 2. spring 10.

Tick capture works as follows.

With its suspension 9, the device is hinged on the hook of the next: 1 machine, with the bar 3 being placed in a vertical position Under the action of a spring: 10 two shoulders 1) arms 1, consumed, allowing the group to snap, and then two arms 2 and 2 squeeze and fix the strap 4, translating it into a horizontal position. When it is, axis 6 interacts with the Z-groove 4 of the strap. When lifting a tick-borne gripper, by a lifting mechanism under the force of gravity of a hooked load, the two shoulders levers 1 continue to compress. Axis 6, slid along the Z-shaped groove 4, is moved all the way to the extreme left position. The plate 3 is rotated by a certain angle under the action of the spring 5 and the axis 6 takes a middle position in the Z-shaped groove 4 of the bar 3. After the product is installed, its gravity ceases to operate. The arms 1 lend by an action of force , axis 6 goes to the extreme right position.

At the same time, the bar 3 again rotates at a certain angle and the axis 6 occupies the uppermost position.

In order to offload cargo, it is necessary to start lifting by hoisting machine. In this case, the two shoulders levers 1 are compressed, the axis 6, moving along the Z-shaped groove 4 of the bar 3, exits the groove 4 and under the action of the spring 5 the bar 3 takes a vertical position. After that, the load is lowered, the two shoulders levers 1 under the action of the spring 10 are consumed. There is an automatic handling of cargo.

Claims (1)

Claims of the invention Tick-borne gripper containing double shoulders connected to a common horizontal axis, on the upper arms of which, by means of horizontal axes, secure the tie rods connected by free ends between themselves and to the suspension for the hook of the hoisting machine with a common horizontal axis, and fixing the double-arm levers at one end on the horizontal axis of the connection of one of the tg with the upper pin of the lever, a bar, at the free end of which a shaped groove is made to interact with the horizontal The other axis of the joint is another bar with the upper arm of the other lever, characterized in that, in order to simplify the design, the common horizontal axes of the bar and two shoulders are spring-loaded one relative to the other, the fixed end of the bar is spring-loaded relative to the adjacent rod, and the shaped groove is made Z- shaped with a muffled end on the side of the lower horizontal section and an open end on the side of the upper horizontal section.
