Abstract

Usage: the invention relates to the mining industry, and specifically to the mine mine-based transport. SUMMARY OF THE INVENTION: A trenching machine includes a platform 1 on a rail track, on which a rotary column 2 is installed, on the upper part of which a telescopic boom 3 is hingedly placed with a bucket 4 and a hydraulic jack. The latter consists of a handle 5 and a lever 6 mounted on an arrow 3 with the possibility of a fixed rotation in the horizontal plane and pivotally connected to the handle, while the hydraulic cylinder 8 controls the handle. The hinge 7 for fastening the lever to the boom 3 is made of two tubular elements with a screw pair 9 for fixing. 1 hp ff, 2 ill. (, /)

Description

FIG, G

The invention relates to the mining industry, in particular to the mine underground transport.

The purpose of the invention is to simplify the design of the trenching machine by eliminating additional working equipment.

This goal is achieved by the fact that a trenching machine for mine workings, including a platform on a rail track, a rotary column placed on a platform, an arrow hinged on a rotary column, a handle, a bucket hinged on a handle, and hydraulic cylinders of a boom, a handle and a bucket, the boom being connected to the hand by means of an intermediate lever mounted on the boom with the possibility of fixed rotation in the horizontal plane and pivotally connected to the hand when cylinder control handle is mounted to five but the intermediate lever and the intermediate lever mounted on the arm by a hinge formed of two tubular elements mounted respectively on the boom and the intermediate lever and having a pair of screw for fixation.

Fig. 1 shows a side projection of a ditch cleaning machine; figure 2 - the same in the plan.

A ditch cleaning machine according to the invention includes a platform 1 on a rail track, on which a rotatable column 2 is mounted, to the upper part of which a telescopic boom 3 with a bucket 4 and a hydraulic-hydraulic mechanism is pivotally attached. The hydro-multiple bucket control mechanism 4 consists of a handle 5, which is approximately centrally hinged to an intermediate (additional) lever 6, which in turn is fixed to a main telescopic boom 3 by means of a planar fixed hinge 7. with a hydraulic jack 8, the other end of which is fixed on the additional lever 6. The hinge 7 is made in the form of a tubular quick-disconnect coupling, the flanges of which are fixed on the ends of the telescopic boom 3, etc. an intermediate lever 6 and additionally fixed by means of a screw pair 9.

The position of the bucket 4 relative to the handle 5 is changed by the hydraulic jack 10. The position of the telescopic boom 3 in

the vertical plane is varied and fixed by the hydraulic jack 11, in the horizontal plane by the hydraulic jack 12, and the change in the boom length - by the hydraulic jack 13.

Platform 1 with a rotary column 2 is made in the form of a frame-oil tank. The platform also contains an oil pump with an engine and a control panel with hydraulic distributors.

The cleaning of drainage channels in the mine workings with the help of a machine is carried out as follows.

To platform 1 from the side of the arrow 3 and

the bucket 4 attaches a mine car with a deep body. An electric locomotive is delivered to the trenching unit where it is necessary to clean the gutter. Depending on the location of the ditch, a telescopic boom 3 with a bucket 4 is installed. The length of the boom 3 is determined by the distance of the gutter from the tracks and the length of the car (distance to the place of unloading). In this case, the boom 3 is set at an angle to the rail tracks, and the additional lever 6 is parallel to the railways and grooves. To set the lever 6 to the required tightening position of the screw

pairs 9 are loosened, and after installation they are tightened again.

The required height of the bucket lift is determined by sliding the hydraulic jacks 11 and 8, and the position of the bucket 4 during scooping,

lifting and unloading - hydraulic jack 10.

As the ditch cleans the machine together

with the car moving along the rail

of the way. By changing the distance between

rail track and ditch the position of the bucket is adjusted by turning the boom 3 in the horizontal plane and turning the additional lever 6 around the hinge 7.
