Description

one

The invention relates to process equipment and is used in industry that extracts mineral resources, in particular, during combine development workings.

The known mechanized drift lining, consisting of two sections, and transverse traverse, reinforced on retractable racks 1.

A feature of this support is that the transverse traverse (top) is made telescopic and with the help of, hydraulic hydraulic piston mechanisms are shifted and moved apart in the longitudinal direction.

Closest to the invention according to the technical solution is a temporary support frame, mounted on a combine, consisting of a top with two racks having retractable shoes 2.

The disadvantages of the known frames are the complexity of the design of the top - the presence of an extra consumer of energy on the frame, and this causes the need for an extra pair of telecommunication hoses for remote installation.

The purpose of the invention is to reduce the size of the top frame and device for its

erection in conditions of flat roofing.

The goal is achieved by the fact that the upper side is provided with a working position stop and a hinge with a vertical axis 5 for folding in the process of shifting, placed in the middle part of the upper one.

FIG. 1 shows the face, fixed by the frames of the temporary support of the proposed design, general view; in fig. 2 - frame 10 temporary support, general view; in fig. 3 - temporary support frame and guide, top view; in fig. 4 — stoppers of the upper frame and guide.

The temporary support frame consists of a top 15 on 1, containing in the plane of the frame a hinge 2 with a stopper 3, and hinged forwards on its sides 4, which at the lower end are equipped with telescopically extendable shoes 5.

20 To relocate the temporary support frames for the face, the sinking combine or a special portal is equipped with a device consisting of a catch 6 and a stopper 7 and a guide 8.

The rearrangement of the proposed temporary support frame is performed as follows.

After driving the production on one frame, the combine is stopped.

The most distant from the fence of the temporary support, close to which the fixed support frame is already installed, is lowered onto the grip 6, releasing the oil from the telescopic shoes 5.

In this case, the stopper 3 under the action of the weight of the top 1 and the entire frame releases the hinge 2.

At the moment of detachment of the shoes 5 from the working soil, the mechanism for moving the gripper 6 along the guide 8 and the frame, folded in the hinge 2, is transported between the standing temporary support frames to the bottom. In the extreme position of the gripper 6 up to 1, the stoppers 7 are inserted, which rise after the passage of the upper one and prevent it from moving backwards.

The reverse of the movement mechanism of the gripper 6 is turned on and the upper to 1 is pushed onto the stoppers 7 and the upper is aligned with the hinge 2.

The telescopic shoes 5 apply pressure, due to which they rest against the soil and raise the upper to 1 above the gripper 6,

and the stopper 3 under the action of its own weight (or spring) falls and locks the hinge 2 in the working position. Continuing to advance, the shoes 5 gush the frame between the roof and the ground, the girrozamkie racks 4 work, and the frame is ready to carry the workload.
