(5) WORKING EQUIPMENT EXCAVATORADRAGLINE

one

The invention relates to earthmoving machines, namely single-bucket excavators with dragline working equipment.

The working equipment of the dragline is known, including the boom with the head blocks, the bucket with the lifting and hauling ropes l.

It is also known working equipment of the dragline, including the boom with the head unit, the bucket with lifting and traction cables 2.

The disadvantage of the equipment is that the precise unloading of the bucket into the vehicles is not ensured, as a result of which the productivity is reduced.

The purpose of the invention is to increase equipment productivity by improving the accuracy of unloading the bucket into vehicles.

This is achieved by the fact that in the working equipment of a dragline excavator, including an arrow, containing

the head part with the block and the middle part, the bucket with the lifting and traction cables, the middle part of the boom is equipped with a winch having installation and lifting cables, the ends of which have an annular clip, freely mounted on the lifting cable of the bucket, while the head part of the boom has an additional block and associated with him lifting cable ring 10 th ring.

FIG. 1 shows a dragline, a general view; in fig. 2 - the lower position of the ring cage when unloading the bucket J in FIG. 3 - top position

15 ring cage.

The working equipment of the dragline includes a sling 1 with the head unit 2, through which the lifting cable 3 passes, connected to the bucket t: B

20 A cable 5 is attached to the bucket at the point where the cable is attached to the bucket’s rocker. In the middle part of the boom winch 7 is installed. It is equipped with cables 8 and 9i and the cable 8 passes through an additional unit 10 installed on the boom bucket TC to the ring holder 11, loosely seated on the lifting weight 3When digging the soil in the face with a bucket C, the ring clip 11 is pulled up with a suspension cable B using a winch 7 DR block 2, loosening the installation cable 9 (the upper position of the ring clip is shown unktirom). The upper position of the ring cage has no effect on the normal operation of the excavator during the mining operation. When the excavator is rotated to unload, the winch 7 lowers the lifting cable 8 and the ring holder 11 under the action of its own weight freely falls along the lifting cable 3 down to the place of its connection with the rocker arm where the shock absorber 5 is installed. Then the winch 7 using the adjusting cable 9 fixed rigidly on the ring cage 11, pulls the bucket C to the required one for unloading-position and releases the haul cable 6. The bucket 6 is unloaded into the vehicle a. During unloading, the installation cable 9 is in a tensioned state, thereby preventing the bucket from swaying and thus providing 9 34 accurate and fast unloading of the bucket into the vehicle. Then the cycle is repeated. Applying the invention provides improved performance by more accurately unloading the bucket over the vehicle. Claims of the excavator docking line equipment including a boom containing a head with a block and a middle part, a bucket with lifting and hauling cables, characterized in that, in order to improve equipment performance by improving the accuracy of unloading the bucket into vehicles, the middle part is equipped with a winch having installation and lifting cables, the ends of which have an annular clip, freely mounted on the lifting cable of the bucket, while the boom head has an additional block, an associated lifting cable holder ring.
