Mine capacitive conveyor
(57) Abstract:Usage: mine conveyor relates to the field of mining hoisting plants for selective movement of minerals, host rocks and materials on steeply inclined and vertical trunks without the use of hoisting ropes, a traction bodies grushovtsy moving along a closed path, according to the continuous distribution scheme. The inventive mine conveyor includes rigidly mounted on the shootings reinforcement rails with curved sections, mounted for movement on rollers, guides covering from two opposite sides, and connected by links with suspended freely on axes bottoms down load-carrying bodies with gears for providing selective movement of the load and actuator in the form of cylinders. On the axes of the links of the hinge is installed and symmetrically placed on two load-bearing body. Axis units are rigidly mounted on the cheeks, on which are rollers. Hydraulic cylinders pivotally mounted and located in the middle part of the axis sequentially along the guides on the reinforcement of the mine workings. The chain will mix as p is oimi the toe rods jumbled links: pushed or lowered, depending on their location in the overall chain conveyor and a given program. 3 Il. The invention relates to the field of mining hoisting plants for selective movement of minerals, host rocks and other materials on steeply inclined and vertical trunks deep mines, mines, without the use of hoisting ropes, a traction bodies, with grushovtsy moved hydraulically in open and closed conduits, discontinuous and continuous distribution scheme.Known devices of continuous operation for transporting materials on steeply inclined plane and vertical, such as:
design by combining two types of transport: vertical and horizontal.with. USSR N 30128 from 08.06.1930, B 65 G 17/36) that to move material vertically, use a bucket conveyor, in which the buckets are attached and move on to the chains;
elevators, including (but.with. USSR N 923317, B 65 G 17/13, B 65 G 43/00, 1982) in which the buckets are attached and move on traction bodies-chains or belts.All these designs use the traction body in the form of chains, belts, ropes. Because of the strength of their traction they did not find and isalnum or steeply inclined trunks.A close analogue of mine magneticly conveyor, patent of Russia No. 1244042, B 65 G 17/00 from 05.07.1984, in which the guides (guides) are moved on the slopes covering the conductors from two opposite sides, which are interconnected trolleys with suspended axles carrying bodies and the actuator. The trolley is supplied successively installed at equal distances from each other stops. Mover-torque and power actuators are placed sequentially on the shootings reinforcement in the trunk with the opportunity to interact with the stops trolleys.On curved sections of road actuators equipped with deflector cylinders.Containers are filled with minerals or host rocks in the pit development on the desktop horizon unload containers on the surface. Materials (dimensions) for delivery to the mine loaded on the surface, unloaded on the desktop horizon.In the movement of mine magneticly the conveyor belt is driven torque and power hydraulic motors, which consistently pairs are located on the executions of the reinforcement in the trunk along the conductors. Joining successively the right, the left system of hydrocele the th curve. Download tanks of cars is carried out with bunkers on the desktop horizon, unloading at the place of installation of the rail, which runs the gear capacity and tilt capacity.Placement drive by shootings in the barrel allows you to damping of each trolley on executions reinforcement of the trunk, the last on the rocks. Mine magneticly conveyor has a greater intensity, significant hard base trolleys is not possible to have small radii curves on the mating conductors guides. It lengthens the overall length of the conveyor, extended generation and associated facilities. The application of the forces of the hydraulic cylinders eccentric to the axis of movement of the trolleys, which leads to imbalance of trolleys, one-sided wear of the rays of rollers and guides.To improve the reliability of the design of the pipeline, reducing the number of cylinders, rollers, reduce metal consumption, the length of the rigid base, the minimum radius of curvature, length of the workings and designs of the pipeline on compound curves, providing axial application force of the cylinders and to unify them, giving of technological design in General equal terms: the depths of transportation and proseware, including rigidly mounted on the shootings reinforcement rails with curved sections, mounted for movement on rollers, guides covering from two opposite sides, and connected by links with suspended freely on axes bottoms down load-carrying bodies with gears for providing selective movement of the load, and an actuator in the form of cylinders, the axes of the links of the hinge is installed and symmetrically placed on two load-bearing body, and an axis of hard-coded links on the cheeks, on which are rollers, when the hydraulic cylinders pivotally mounted and located in the middle part of the axis sequentially along the guides on the reinforcement of mines.As in the prototype chain can be moved in open and closed conduits.Moving is power cylinders, which their toe rods move links: pushed or lowered, depending on their location in the chain conveyor and the specified program.In Fig. 1 3 depicts the link conveyor with hydraulic power cylinder.In Fig. 1 a front view; Fig. 2 is a side view, and Fig. 3 in planetary rigidly mounted axle 5.On the axis 5 on the hinges 6 installed capacity two protonotes 7 in such a way that always take the position head down with a toothed wheel 8.The connection 9 between the links via the hinges 10. They oversee distances and ensure the sustainability of the link.The moving parts of the conveyor exercise of the power cylinders 11. They are mounted on hinges 12 on the reinforcement of the stem 13 in either direction from the axis along the conductors 1.Hydraulic cylinders the piston rods 14, Fri 15, gliding over the grooves 16, move axis 5 together with placed on them carrying bodies 7, along the guides on the trunk and adjacent workings.Movement is both closed and open-ended conductors incorporated in the work right (downstream) of the cylinders. Their heels 15 rest against the axis 5 and move the link to the full stroke distance equal to the step size between adjacent axes 5.The left hydraulic cylinders are in their initial position. When the movement of the rods 14 of the right-wing cylinders are approaching the maximum, included the cylinders left. Their heel 15, sliding troughs 16 are in contact with the axis 5 with the of ingrow and they occupy the original position.The power cylinders 11 left move the rods 14 Fri 15 conjugate chain conveyor until end of turn stem.Included right cylinders and, thus, the driven shaft conveyor.As in the prototype, the conveyor may be operated through one trunk, and shifted opubco, two barrel. The loading conveyor is made under the bunkers in unloading the yard by the nature of the cargo.The unloading conveyor is made selectively in the field installation of the rails. The cylinders are distributed along the conveyor rails (guides) on the shootings. The pipeline consists of individual links. Each link unloads his load on the execution of the last one on the rocks, which will take place the barrel. Mine conveyor, comprising rigidly mounted on the shootings reinforcement rails with curved sections, mounted for movement on rollers, guides covering from two opposite sides, and connected by links with suspended freely on axes bottoms down load-carrying bodies with gears for providing selective movement of the load, and an actuator in the form of hydraulic cylinders, otlichie links rigidly installed on the cheeks, on which are rollers, the hydraulic cylinders pivotally mounted and located in the middle part of the axis sequentially along the guides on the reinforcement of the mine workings.
FIELD: metallurgy; rolling.
SUBSTANCE: invention can be used for transportation of hot-rolled coils. Proposed conveyor chain has identical-shape links interconnected by axles, with fork at one end and eye at the other end of each link. Fork and eye are provided with link turning angle limiters in vertical plane made in form of solid end-face flat bevels over entire width of link. Bevels are mated with load-carrying surface of links at equal angle of tilting to said surface. Projections forming slot are made on outer vertical surface of one of fork cheeks. Head of axle with flats is fitted in said slot.
EFFECT: improved serviceability and reliability of conveyor chain.
