Description

The utility model relates to road-building machines, in particular to excavator-type earth-moving machines, and is intended for snipping pipes during repairs.

Famous single-bucket hydraulic excavator (Berkman I.L., Rannev A.V., Reish A.K. Single-bucket construction excavators: Textbook for medium vocational schools - 3rd ed., Revised and additional - M: Higher. school., 1986. - 272 pp., ill. - (Vocational education) p. 78-82), the working equipment of which consists of an arrow, a stick, a bucket, hydraulic control cylinders.

However, the known device has the following disadvantages:

- the inability to dig the pipeline from two sides without moving the excavator;

- decrease in performance when fragmenting pipelines due to the increase in cycle time.

The closest known by technical nature and the achieved result is the working equipment of the excavator (Gavrilov NI, Litvak A.E., Ionin Yu.N. et al. Hydraulic excavator EO-4121. - M.: Mechanical Engineering, 1980. - 232 p. (Pp. 172-173)), containing: boom, stick, bucket, control hydraulic cylinders. The working equipment is fixed on the frame of the excavator and does not have the ability to move across the excavator.

The known device has the following disadvantages:

- the inability to dig the pipeline from two sides without moving the excavator;

- decrease in performance when snatching pipelines due to the increase in cycle time.

The objective of the invention is to increase productivity during stripping operations, expanding the functionality of the excavator.

The specified technical result is achieved by the fact that the proposed working equipment of the excavator, consisting of an arrow, a stick, a bucket, control hydraulic cylinders, is mounted on a movement mechanism equipped with two telescopic hydraulic cylinders, and is a trolley with metal rollers in contact with a guide beam fixed to the frame of the excavator while the rails are fixed on the platform, on which the trolley is mounted using rollers. By means of the movement mechanism and telescopic hydraulic cylinders installed on it, the movement of working equipment is carried out.

The invention is illustrated by the accompanying drawings, in which Fig. 1 shows an image of the working equipment of the excavator, side view, Fig. 2 shows the image of the working equipment of the excavator, top view, Fig. 3 shows the image of the working equipment of the excavator with the moved position of the working equipment, top view, figure 4 shows the image of digging by an excavator pipeline, side view.

The excavator’s working equipment includes boom 1, two boom hydraulic cylinders 2, handle 3, handle hydraulic cylinder 4, bucket 5 and bucket hydraulic cylinder 6, movement mechanism 7, two movement mechanism hydraulic cylinders 8, guide beam 9,

rollers of the movement mechanism 10, rails 11, support rollers of the movement mechanism 12. The boom 1 and two hydraulic cylinders of the boom 2 are attached to the movement mechanism 7, the telescopic hydraulic cylinders 8 are attached to the upper part of the movement mechanism. The movement mechanism 7 is a trolley with rollers 12 that move along the rails 11 and the rollers 10 along the guide beam 9. The movement mechanism is mounted on the guide beam 9 and prevents tipping of working equipment. The movement mechanism allows you to move work equipment with the goal of digging pipelines on both sides and for digging soil over pipelines without moving the excavator. This scheme of the working body allows with less time to carry out overburden work in the repair of pipelines.

When opening the pipeline, the movement mechanism first moves the working equipment to one side of the pipeline and digs it out, then over the pipe and on the other side of the pipeline.
