(54) PLATFORM FOR FIXING REPAIR EQUIPMENT

one

This invention relates to the mechanization of repair work in mine metallurgical units, such as blast furnaces, and air heaters.

A device for fixing repair equipment in blast furnaces is known, comprising a platform with sliding telescopic rods. The necessary equipment is placed on the site or the actuators are suspended from it. The boom extension system is either hydraulic or combined - hydraulic with mechanical. 1.

The drawbacks of the device are complicated; the design of the structure and its maintenance in connection with the presence of 1 pumping station and hydraulic devices.

A device for fixing reylon equipment is known, comprising a platform with telescopic distance beams fixed in extended positions with pins. At the ends of the telescopic spacer beams screw jacks are fastened. When securing the platform in the furnace, the beams are preliminarily advanced by a certain amount, they are fixed and then the gap between the furnace wall and the beam is selected using screw jacks 2.

The disadvantages of this device include: low installation performance, due to the need to adjust each screw pair separately; The reliability is due to the fact that inaccuracy in adjusting at least one of the pairs causes an uneven distribution of loads on the elements of the device;

Q is a hard working condition, as each pair is adjusted manually in the repair area.

The purpose of the invention is to increase productivity, reliability and improve working conditions.

Claims (2)

15 The goal is achieved by the fact that in the site for fixing repair equipment, mainly in mine-type devices, including a working steel with retractable spacers and re2Q support elements that are guarded in length, the adjustable support elements are made in the form of flexible rubber-cord shells attached to the hinges of the joint. At the same time, the platform can be equipped with a protective metal support fixed on the supporting rtoBepxHOCTH shell. On fng. 1 shows the proposed site, general view; in fig. 2 - position of the telescopic rod relative to the wall of the metallurgical unit before filling the rubber-casing shell with air; in fig. 3 - the same, after filling the rubber-cord shells with air. The platform contains working flooring 1 with air preparation unit 2 and distribution device 3 placed on it. Spacer rods 4 consisting of fixed 5 and retractable sections are attached to the platform from 4 sides. Fixing the relative position of the sections is carried out with the help of a screw 7 through the holes 8 in the sections. At the ends of the sliding sections 6 of the Shchtang 4 there are adjustable supporting elements, each of which contains an oiory plate 9 fixed to the sliding section b by means of a joint 10. The flexible rubber-cord shell 11 with a protective metal support 12 is strengthened to the plate 9 device 3 through the pipelines 13. The device operates as follows. A site with maintenance equipment is installed in a metallurgical unit. An air line is connected to the site for feeding the air shells 11. The sliding sections 6 of the spacer bar 4 are installed so that between the supporting surfaces of the protective metal supports 12 installed on the air shells 11, and the wall of the metallurgical unit have a gap axial direction of the metallurgical unit. After fixing the retractable rod 6 from the 6, with respect to the fixed section 5, air is supplied to the pneumatic shells by means of a screw 7 from the distribution device. relative to the hinge 9 to the orientation of the protective metal support 12 parallel to the wall of the metallurgical unit. If necessary, the platform 1 along the osmi-metallurgical unit relieves pressure from the pneumatic shells 11, and, without changing the relative position of the sliding 6 and stationary 5 sections, the platform is moved and refilled the pneumatic shells 11. The formula of the invention. A platform for fixing repair equipment, mainly in mine-type devices, including a working floor with retractable spacers and adjustable bearing elements, which, in order to increase productivity, reliability and improve working conditions, the adjustable support elements are made in the form of flexible rubber-cord shells attached to shchtangam sharnirio. 2. The platform of claim 1, wherein each shell is provided with a protective metal support fixed to the shell support surface.
