Description

The invention relates to construction, in particular, to devices for carrying out work within mine structures.

A well-known cradle for construction and installation work, including a frame with a working platform, flexible suspensions attached to support beams installed on the floor of the building, electrically operated winches, an electrically driven power cable, and an electrical cabinet. In order to enable electric welding work from the cradle, it is equipped with a cable entry device made with a removable key and mounted in a cabinet with electrical equipment on an insulating base, and flexible hangers are attached to the support beams by means of electrical insulating sleeves.

The disadvantage of this device is the impossibility of carrying out welding work in the ends of the cradle with the existing method of protecting suspensions. Welding is possible only in a certain area along the longitudinal side of the cradle.

The closest to the proposed technical essence and the achieved result are the scaffolding for the performance of work inside the structures of the column type, containing a support frame, a loading area, flexible suspension with a drive winch with spring-loaded rubberized rollers and electrical equipment.

The disadvantage of these scaffoldings is the impossibility of their use.

And s

for installation of elevator equipment, as they are applicable only for the production of works inside structures of column type. In addition, these scaffolds are difficult to operate, there is no possibility to feed materials into the elevator shaft, they are not intended for welding. Since the brackets of the guides and the elevator doors protruding from the plane of the wall are installed in the elevator shaft, these scaffolds will not be able to move inside the shaft.

The purpose of the invention is the acceleration of the installation of elevator lifts.

This is achieved by the fact that the device, which includes a support frame, a loading platform, flexible suspensions with a drive winch, insurance catchers, expansion brackets with spring-loaded cut-off rollers and electrical equipment, is equipped with two working platforms suspended in height, the flexible suspensions are located along to the sides of the platforms and kinematically connected to catchers, which are fixed on the upper working platform, and expansion brackets with rollers are mounted on the sides of the slave chih sites,

In addition, the cargo area has cargo access hatches and a rotary lifting boom with a drive winch.

Such a constructive implementation of the device allows for installation and welding work along the entire perimeter and along the height of the shaft.

Two working platforms suspended in height on the cargo platform move with the fitters to the required height, which enables workers to assemble and weld elevator equipment from these platforms.

The removal of flexible hangers from the working area and placing them in the hollow racks of the frame of the lower working platform allows you to free up working space, thus providing ease of installation work and also increase safety, as it protects flexible hangers from sparks during welding.

Spacer brackets with rubberized rollers spring-loaded to them prevent the platforms from swaying during movement, increase the stability of the platforms and prevent their engagement with the brackets protruding in the shaft, thus increasing the safety of work.

A rotary lifting boom located on the frame of the cargo platform allows the elevator equipment to be fed through the loading hatches,

5 placed in the flooring of this site, in the mine to the place of installation.

FIG. 1 shows the device, a general view; in fig. 2 - side view; in fig. 3 and 4 are diagrams of mounting the guides and the two legs.

The device consists of a cargo platform 1 with a support frame 2 and a frame 3. The support frame 2 of the cargo platform 1 is installed on the top element of the shaft 4. On

5 frame 3 of the loading platform 1 is mounted with a lifting boom 5 with a drive winch. In the floor of the cargo area 1, there are load-lifting hatches b, through which the pivot cargo lifting boom 5 feeds equipment into the mine. Upper working platform 9 with frame 10 is fastened to the cargo platform 1 by means of flexible connections in the form of a lifting 7 and a safety 8 cables.

5 On the frame 10 there are two electric friction winch 11 with centrifugal catchers 12 and an electrical equipment cabinet 13. The lower working platform 14 with frame 15 is attached to the frame 10 of the upper working platform 9 diverting blocks 16. Lifting 7 and a safety cable 8 bends around blocks 16 and passage

5 inside the hollow pillars 17 of the frame 15 of the lower working platform 14. On the sides and frames 10, 15 of the upper 9 and lower 14 working platforms, spacer brackets 18 with spring loaded rollers 19 are hinged.

The device works as follows.

Swivel lifting boom 5 through located in the cargo area

5 1 cargo passages 6 to the place of installation are supplied with all the necessary equipment for elevators (brackets, guides, doors, equipment, etc.). For this purpose, pivot boom 5

0 made with the possibility of installing it in different places on the fence of the cargo area 1,

From the lower working platform 14, electric welding is carried out to install the bracket in the mine. Then, guide rails of the elevator and counterweight are mounted. Installation is carried out by two installers from two work sites 9, 14. The rotary load-lifting boom 5 guides are held in a vertical direction.

the position, and the installers, one on the upper working platform 9, and the other on the lower working platform 14, attach them to the previously installed brackets.

The device is controlled by means of a console located on a flexible hose and allowing control from any of the work sites and remotely.

After the assembly of the guides, the installation of the shaft doors is carried out. From the two work sites 9, 14, the fitters perform a temporary fastening, alignment and then permanently fasten by welding.

From these sites, electrical wiring, elevator signaling control circuits are installed with the installation of electrical apparatus of the mine and calling devices at landing sites.

After completion of all work in the elevator shaft, the device is dismantled.

Reduction of labor costs during installation of guides, brackets and doors is ensured with the exception of

the technological process of preparatory work associated with carrying shields and bars to the floors of the mine, followed by disassembly and monolithing of the mine pockets.

Improving safety, especially in the winter period and reducing the consumption of materials, is achieved by eliminating the need to use wood shields during the installation process, the period of which does not exceed 0.5 g.
