Abstract

FIELD: mining engineering.

SUBSTANCE: method of assembling a metal stripping copro with pads on the platforms includes an integration assembly on the stand of the main blocks of the copra in the form of a central tubular stand, a mooring line, a continuous and constant podshnevnyh platforms and a machine, and then mounting them above the mouth of the vertical trunk. The first on the foundation in the design position is installed the central tubular post and to it is mounted and attached the mounted jib, then on the ground at the zero mark above the mouth of the vertical trunk a perforation pad is constructed, consisting of two identical parts, which then rises along the guide central tubular column and Is fixed in the design position, and then a permanent pad platform is assembled on it, which, in turn, also rises along the guide of the center pillar and fixed in the project position.

Description

The technical solution is intended for use in the mining industry, namely in the construction and operation of shaft vertical shafts.

In the practice of building coal and ore mines, various designs of metal mowing machines are used: four-post, four-post with two jibs, tent and A-shaped, which due to their design features are separated during installation work into separate large mounting units structural elements. Depending on the design of these elements, weight, height, a given deadline for putting the copra into operation, the installation method is selected, on which economic and technological indicators depend.

There is a method of mounting a mine sloping tent-frame metal pile driver with a pendant machine, adopted as a prototype, including an enlargement assembly on the stand of the main blocks of the pile driver: a machine with podshkivny areas and podshivnoy device in the form of a tent with their subsequent installation over the mouth of a vertical shaft (Yakimenko A. P. Designing slanting mine pile drivers of a new type / A.P. Yakimenko, S.F. Zolotarev // Mine construction, 1981. - No. 9. - C 20-21).

The disadvantage of this method is the complexity and the complexity of the installation of the shaft sloping hipped-frame metal headstock, which consists in the following:

- the copra machine, consisting of two enlarged spatial blocks weighing 80 tf each, is mounted together with the underframe pads on the assembly stand and for moving them to the installation site, the device of knurling tracks and the use of special equipment are required;

- for the installation of a copra machine with cushion pads in the design of a tent-frame copra, it is necessary to use special lifting devices mounted on the tent structure, the weight of which must exceed the weight of the copra machine with pivot pads, which requires a lot of labor and time;

- the assembly assembly of the jib hinges of a tent-frame copra weighing 100 tf each is carried out simultaneously with the assembly of the copra machine with the underfloor platforms on a special stand located near the mouth of the vertical trunk, and their connecting assembly in the vertical position is carried out using sophisticated equipment: mounting masts, 50-ton chain hoists, winches and cranes, which requires large labor costs;

- when mounting the copra machine, double alignment and straightening are required - when enlarging the assembly of spatial blocks with podkivnoy platforms on the assembly site and then, when installing the machine with podkivnoy platforms at a height in the tent-frame copra.

Thus, in general, the installation of a sloping hinged-frame copra requires a lot of labor, time and stopping to work on the trunk.

The technical result of the proposed technical solution is to increase the efficiency of installation of a metal mine head, reducing the complexity and economic costs and eliminating a long break in the work on the trunk.

The specified technical result is achieved by the fact that the method of installation of a metal mowing head with podkvichnymi platforms, including enlarging the assembly on the stand of the main blocks of the copra in the form of a central tubular stand, jib, sinking and constant podkashivnyh platforms and the machine, followed by their installation over the mouth of a vertical shaft, which in that the central tubular stand is installed first on the foundation in the design position and the mounted jib is installed and attached to it, after which on the ground at a zero mark above the mouth of the vertical trunk, a tunneling platform is assembled, consisting of two identical parts, which then rises along the guide of the central tubular column and is fixed in the design position, and then a permanent suspension platform is assembled on it, which, in turn, also rises along the guide of the central tubular rack and secured in the design position;

- a method characterized in that a machine made of separate ring elements is mounted above the barrel’s mouth using a tunneling pad as a mounting platform.

The claimed technical solution is illustrated by drawings, where in FIG. 1, 2, 3 shows the sequence of installation of a metal mowing head with podshkivny platforms, and in Fig. 4 - mounted pile driver with podshkivny platforms and the machine tool.

Installation of a metal mowing head with podshkivny platforms is carried out in the following sequence. On the assembly stand, located in the immediate vicinity of the barrel under construction, is the assembly in the horizontal position of the Central tubular rack 1 . The assembled stand by the sliding method with the help of two cranes working as a mast, is pulled to the trunk, brought into a vertical position and mounted on the foundation in the design position (Fig. 1, a).

On the assembly stand, an enlargement assembly of the jib 2 is also carried out in a horizontal position, followed by sliding to the barrel using two cranes, where it is installed in the design position and secured to the central tubular post 1 (Fig. 1, b).

Driving pad 3 assembled on an assembly stand in the form of two blocks, which are individually moved to position I at elev. ± 0.00 m, where they are interconnected (Fig. 2, a). Using two taps using a central tubular standoneas a guide, tunneling pad 3 raise to the design position (Fig. 2, b).

The permanent underfloor pad 4 is also assembled on the assembly stand in the form of two blocks, which are individually moved and stacked on the underfloor pad 3 using two cranes (Fig. 3, a). On the tunneling pad 3, the final assembly of the permanent mounting pad 4 from two enlarged blocks and its rise to the design elevation (Fig. 3, b) are performed. Lifting is carried out using two cranes using the central tube rack 1 as a guide.

Machine 6 (Pat. 154286 U1 (RU), Е04Н 12/26) consists of annular elements 5, which are individually moved and stacked on a tunneling pad 3 for subsequent installation by the method of "top-down" above the mouth of the barrel 7 (Fig. 4).

The effectiveness of the proposed method of installation of the mowing head with podshkivnyh sites is estimated by:

- use of the central tubular stand as a guide, which significantly reduces the number of straightening and alignment of structures during installation;

- reduction of labor costs for installation of podshkivny platforms;

- the use of subsurface pads as assembly and assembly;

- reduction of labor costs for the installation of the machine, which is assembled independently of the podshchivnyh sites and other structural elements of the copra;

- the absence of labor costs on the device of the rolling paths for feeding the ring elements of the machine to the installation site due to their low weight;

- reducing the weight of the copra due to the use of light metal structures of variable cross-section and breaking them into mounting blocks of light weight;

- reduction of the total installation time of the copra and, in connection with this, a significant reduction in interruptions in the production of work on the trunk, a significant reduction in the total labor costs and the cost of installing the copra;

- minimizing work at heights.
