Description

 The invention relates to devices such as guide rollers for mine lifting vessels, stands and skips.

 Known devices for eliminating lateral vibrations of stands and skips when moving in the trunk. Guide stands are installed on the stands and on the base / frame / skips, which are either in the form of cast steel staples or sliding shoes that are in contact with the conductors. These include the devices described in the book Stationary Machines, Moscow, Nedra, 1389, p. 347. The terminological dictionary "Mining", Moscow, "Nedra", 1981, p. 233.

 A big drawback of such sliding type devices is a high coefficient of friction, inserts into staples / paws, shoes / guiding supports are quickly worn out, and the conductors wear out a lot.

 This leads to frequent replacement of inserts and conductors.

 Known devices for eliminating lateral vibrations of the cage and skip when moving along the trunk - on the frame of the skip and the sides of the cage are mounted rotation bearings - roller guide bearings - prototype, which are in contact with the conductors. "Stationary machines", Moscow, "Nedra", 1989, p. 347, 348.

 The use of roller guide bearings, covering conductors in the trunk on a box-type type on three sides, eliminates lateral vibrations of lifting vessels, stands and skips and reduces the friction of the guide bearings on conductors compared to sliding bearings. These guide bearings consist of three rollers located on three sides of the conductor, which move along massive box-type conductors.

 In order to increase the reliability of the design to reduce the friction of the guide bearings on the conductors, to reduce the metal consumption of the supports, the metal consumption of the conductors, to make the design of the supports more adaptable under the general equal conditions of eliminating the lateral vibrations of the lifting vessels when the vessels move along the conductors in the barrel, a new design of the guide support is proposed.

 The specified technical result is achieved by the fact that instead of the guide supports of the types of shoes, guide rollers on the stand or skip frame, rectangular pivots are installed. At the free ends of the trunnion, replaceable rolling inserts are installed, consisting of a hollow rectangular base and part of the separator with rolling elements - balls.

 In the trunk of a vertical shaft or mine, metal guiding conductors are hung at the gutter profile on executions.

 The guiding bearings of the cage or skip frames, consisting of trunnions, on the free ends of which are installed replaceable rolling liners, consisting of a hollow rectangular base and part of the separator with rolling elements - balls that come into contact with opposite inner surfaces of the groove-shaped profile of metal conductors that perform also the role of the rolling guides, we will call the rolling guides.

 The conductors in the trunk are hung and operated in compliance with the requirements of the "Instructions for the production and acceptance of work on the reinforcement of the shafts of vertical shafts" SN 340-65 Gosstroy b. USSR and should not have a widening gauge of more than 8 mm.

 In order to correct the distances between the guide of the rolling support and the inner surfaces of the guides of the metal conductors, the interchangeable bearings are installed on the seat of the interchangeable bearings on the trunnion of the guide of the rolling support with the possibility of adjustable movement by means of a clamping spring.

 The use of a rolling bearing part on the rolling bearings of the lifting vessels reduces friction when the vessel moves along the metal guiding conductors in comparison with the use of rollers, reduces the metal consumption of the guiding bearings, conductors, increases manufacturability, reduces operating costs, increases the reliability and safety in operation - even with the destruction of replaceable bushings in the barrel, the vessel does not go out of the dimensions of the guide conductors - under general equal conditions for the exclusion of transverse fluctuations during the descent, ascent of vessels-stands or skips for withdrawal.

 The device is illustrated by drawings.

 Stand 1 (Fig. 1 and 2) - during descent and ascent along the shaft of a vertical shaft or mine, it moves on metal guide bearings 2, on the inner surfaces of the groove-like profile of metal guide wires - guide rails 3, on interchangeable rolling liners made on a hollow base rectangular shape 4, on the rope 5.

 Skip 6 (Fig. 3) during the descent, ascent along the shaft of a vertical shaft or mine, moves on metal guide bearings 2, along the inner surfaces of the metal trough-like profile to conductors - guide 3, on removable rolling bushings made on the basis of a hollow rectangular shape 4, on the rope 5.

 On a hollow rectangular base of replaceable rolling bushings 4, parts of the inverse hemispheres 7 and reinforced parts of the separator 8 cells are made, in which rolling elements are installed - balls 9 that are in contact with the inner surfaces of the groove-like profile of conductors - rolling guides 3, along which the balls of replaceable rolling liners 4.

 The conductors in the trunk are hung and operated in compliance with the requirements of the "Instructions for the production and acceptance of work on the reinforcement of the shafts of vertical shafts" SN 340-65 Gosstroy b. USSR and "Instructions for the production of surveying works", Moscow, "Nedra", 1987, p. 63, p.13.1.3, according to which the deviation of the gauge of metal guide conductors from the project is allowed up to 8 mm. To correct the distances between the two guide bearings, the inner surfaces of the guides of the metal conductors 3, replaceable liners 4 installed on the seats 10 with the possibility of movement on the seats. The correction of the movement of the replaceable rolling liners 4 at the seats 10 is carried out by the adjusting hold-down spring 12 with the washer 13 installed in the groove 11 made of a round shape. a stopper 14 made in the body of the seat of the replaceable rolling insert 10 and is retained in the groove 15 on the replaceable rolling insert.

 Guide rolling bearings reduce friction during movement of cage or skip vessels along metal guide conductors along the shaft of a mine or mine compared to the use of rollers, reduce metal consumption, maintenance costs for repairs, and increase safety when moving vessels along the barrel since even in case of failure of replaceable rolling shells, the rolling guides do not go out of the contour of the guiding metal conductors of the groove-shaped profile.

 The use of rolling bearings on moving vessels of mine hoisting devices increases manufacturability, reliability and safety during operation, while maintaining the same conditions for eliminating transverse vibrations of the stand or skip during the descent-ascent along the shaft of a vertical shaft or mine.
