Abstract

1428567 Supporting hoses CONTINENTAL OIL CO 18 Sept 1973 [3 Oct 1972] 43731/73 Heading F2P A pair of hoses 13a, 13c, Fig. 1d, between a coal &c. mining machine 14 at a workface 12 and a terminal 16 to which water is supplied and from which slurry (a mix of coal &c. and the water) is pumped, includes slack to allow the hoses to move as the mining machine advances, the hoses being held off the ground. The hoses may be lifted by an overhead crane system. As shown, various forms of wheeled conveyers are used. Endless tracked carts 18 (see Fig. 2) powered by electric motors may support hoses 30, 31 one above the other in clamps 32. A 180 degree turn between hose sections 13a, 13c, Fig. 4, is effected by a conveyer 22. One such conveyer, Figs. 5, 7, is pulled or pushed by a tractor 74 and comprises side plates 71, 72 journalling conveyer rollers 73. The conveyer 22 is moved along the ground on rollers 76a, 76b which hold it at an angle to the ground (Fig. 7). Carts 80, 90, which are powered and unpowered, respectively, are connected by links 40 which are of a length to maintain correct spacing of the hoses 13 secured to the carts as they negotiate bends. The wheels of the carts 80, 90 are raised off the ground as they travel over the conveyer 22. In another form of conveyer for effecting a 180 degree turn of the hoses, the links 40, Fig. 8, connecting the carts 80, 90 carry guide discs 103 which engage a curved vertical track 101. Ground engaging wheels 42 support the conveyer. For a 90 degree turn, the guide discs 103 engage a track (200), Fig. 9 (not shown), on the ground. The powered carts, Figs. 13, 15, have each ground wheel 81 driven by an hydraulic motor 102 fed from a pump 104 actuated by an electric motor 105. The control valves 106 of the pumpmotor circuits are connected by control cables 115, 132 to the corresponding control valves of the adjacent powered carts. The arrangement is such that when one powered cart starts or stops, the adjacent carts move similarly. Wheel speed control arms 120, 121 depending below the powered carts engage steering rails (200), Figs. 18, 19 (not shown), secured to the ground where the carts have to negotiate corners. An explosion-proof box (317), Fig. 17 (not shown), on the unpowered carts 90, houses the electric controls for the system, Fig. 20 (also not shown).

Description

one

The invention is fire based in the mining industry and can be used to transport slurry hoses.

A known system that allows for smooth rotation during continuous transportation of rock mass through a system of cross-cutting mine workings, consisting of straight line sections of conveyors mounted in the mine workings and interconnected in the interface of the above mine workings the linear sections arranged at an angle to each other and the above sections llj.

The disadvantage of this system is that when it is used for transporting hoses, difficulties arise when the hoses are built up in conditions of constantly moving mines.

A system for transporting hoses is also known, comprising wheeled carts spaced from one another and connected by means of traction bars on which a hose is attached, attached at one end to the suspension bunker 1 2 J.

5The disadvantage of this device is the low reliability of maintaining the hoses both in the working position, in the tension state, and in the free state. condition.

10 The purpose of the invention is to increase reliability by maintaining hoses in a nat.

The goal is achieved by the fact that the system is equipped with a reserve part, consisting of two branches, and waiting for the hose to rotate at an angle of 18 °, which is installed in the reserve section.

FIG. 1 shows a basic 20 arrangement of hoses in a mine work system; in fig. 2 - a system of hoses in the mine workings supported by carts; in fig. 3 is a system for transporting hoses, o & axonometric view. 393 A system for transporting hoses is installed in mining section I, with which production 2 and 3 are conjugated. Along production 1, a pair of sludge passes, containing an accumulation section 4 which forms a turn on at point 5 and. forms a working section 6 connected to a food supply system and a suspension connected to the ironmaker 7. The free end of the hoses 8 is connected to point 9 of the feed line. The hoses are supported along the entire length of the trolleys 10. The system also provides a guide II when rotated by 90, and each of the trolleys Yu includes connecting means (ties) 12 connecting each of the trolleys to each other. Rotation by 18O is carried out through the conveyor platform 13, consisting of. the central part (pad) 14 and the two side parts 15 and 16. A plurality of wheels 17 is attached to it with freedom of rotation. The conveyor mobility is provided by the tractor 18. At the outlet of the hose system, one hose is connected to the hopper 19 and the other to a suspension pump. The system 11 is equipped with a conveyor 21 for the direction of the bogies of Yu. The system works as follows. As the product, such as coal, is removed by the cutting machine 7, the product is caught by the conveyor and transferred to the crusher, the crusher is well known in; technology and may have several options. The crusher system may also include a fine particle separator. The water level sensor maintains the level of the Buscher 19 at a given height, regardless of the amount of coal coming from the crusher to the bunker. One of a pair of hose; gov supplies water, while the other takes a liquid mixture of the product, called a slurry. Usually, the last hose is connected to the outlet of the suspension pump 2O, which pumps the product and water from the hopper 19 and pumps it to the discharge point 9. As the iron machine 7 moves to a new formation, coal force is transferred through connections 12 to each of the working trucks section 6 of the suspension system. As the working section moves in direction 74 of arrow 22, cumulative section 4 should become shorter, therefore transporter 13 should move in direction of arrow 23. When truck Yu reaches the conveyor, it rolls along side 15 around platform 14 to side 16. The movement of the cutting machine back from the production of the communication management system 12 is reversed, causing the carriage 10 to move in the direction 24. As the working section will now move in the direction 24, it will be necessary to lengthen the storage section 4. To accomplish this movement, the conveyor 13 must move in the direction of the arrow 25, the conveyor 21 provides the direction of the carriages and the communication system along the arc of rotation 90, protecting the suspension hoses from damage that could be caused by friction about the angle mine workings. The proposed device for conveying gylangs makes it possible to increase the wear resistance of the latter by increasing the reliability of maintaining the hoses both in the tensioned and free condition and to exclude their contact with the walls of the mine workings and in the places of their junction with each other. Formula of reel and system for transporting hoses, including wheeled carts located at a distance of one another and connected by means of rods on which a hose is attached, attached at one end to the suspension bunker, characterized in that In order to increase reliability by maintaining the hoses in tension or in a free state, the system is equipped with a reserve section consisting of two branches and a means of turning the hose at an angle of 18O installed in the reserve section.
