Abstract

The invention relates to lifting and handling equipment, in particular in crane mechanical gripping devices for reloading packages of round wood in sling. The purpose of the invention is to increase the safety when the hooks interact with the bundling of the attachment. The hooks are made of the upper link 3 moving in translation in the guide tube 9 of the carriage 2, and the lower link 4 connected by a hinge 5 coming out of the load from the guide tube, which, when the hooks of the gripping device are turned, rotates relative to the hinge axis in the direction of the seized load sling, preventing the sling from dropping from the lower link of the hook. 3 il.

Description

The invention relates to hoisting equipment, in particular to crane mechanical gripping devices for reloading balances (packages) of round timber in a sling harness from the water to the ship.

The purpose of the invention is to increase safety during the interaction of hooks with the sling of the package.

Figure 1 shows a gripper, General view; figure 2 is the same, a top view; in Fig.3 - section aa in Fig.2.

The device comprises a frame 1 with horizontal guides, carriages 2, bearing hooks consisting of an upper link 3 and a lower (gripping) link 4 connected by a hinge 5. The lower link 4 of the hook can move translationally in the guide tube 9 of the carriage 2. Two pairs are attached to the guide frames track rollers 6, end blocks 7, block device 8. The roundwood package 10 is fastened with sling straps 11.

The device operates as follows.

The operation of the device is controlled by a crane operator using a two-rope crane system, end blocks 7 and block device 8.

After installing the gripping device suspended on the crane with the carriages 2 on the forest pack 10 support rollers 6 with the smallest possible angle between the longitudinal axes of the gripping device and the package, the hooks are pulled apart by selecting one of the two ropes of the crane when the other is loosened.

The lower parts of the 4 hooks located below the level of the track rollers 6, moving between the logs of the forest package, come into contact with the slings of the strapping 11 of the package, causing them to tension. When this capture is automatically installed symmetrically with respect to the slings of the strapping 11 using the block device 8. The load is carried out with the subsequent lifting of the gripping device with both ropes. Moreover, under the influence of the load, the hinge 5. connecting the lower (for the gripping) link 4 of the hook with the upper one, which moves only translationally in the guide pipe 9 of the carriage 2 of the gripper, leaves the pipe. This allows the lower link 4 of the hook to rotate relative to the axis of the hinge 5 in the direction of the captured sling of the strapping 11 of the package, which prevents the self-suspension of the suspended load in the case of inclusion of the rope selection information carriages 2.

After sequentially installing the load on the site and capturing the load, the carriages 2 are reduced to the stop. In this case, the lower links of the 4 hooks, moving between the logs at the lower level of the strapping of the strapping 11, are subsequently freed from the strapping of the strapping 11 of the load with the subsequent lifting of the gripper.

Freight hooks with the help of springs 12 are raised to their original position, in which the hinge 5 is located in the guide tube, which eliminates the possibility of rotation of the lower link 4 of the hook.

Claims (1)

Claim A device for capturing packages of timber containing a frame mounted on a crane lifting device with horizontal guides and mounted in the latter carriages, connected by means of a cable block system with a lifting device and having gripping hooks, characterized in that, in order to increase safety when hooks interact with the strap of the package , each carriage is provided with a guide in the form of a pipe vertically placed on it, and the hook connected to this carriage is made integral of pivotally connected links installed in the pipe with the possibility of limited vertical movement with the placement of the hinge connecting the links in the latter, spring-loaded in the direction of this movement and turned with its bent end to the side opposite to the middle part of the horizontal guide carriages, FIG.
