Description

; 54) TOWER INSTALLATION FOR CUTTING EXTREME

one

The invention relates to ropeway type vehicles and can be used in the mining, construction and other industries.

The known suspended tower installation for backfilling of grooves, containing movable supports with drives of a carrying rope mounted on them with two parallel branches and a pull rope with trolleys 1 fixed on it.

The disadvantage of this cableway is low efficiency when working together with different types of transport in some technological schemes, for example, in cyclic-continuous mining of minerals in quarries. In particular, for working with conveyors by trains, due to the relatively low carrying capacity of the rolling stock of the cableway, it is impossible to organize a continuous reloading of the rock mass from the conveyor train. It is also impossible without additional crushing to provide loading with rock mass, since the maximum size of a piece transported by a conveyor train is 1200 mm, and transported by a trolley is 160 mm.

The purpose of the invention is to increase the capacity of the installation.

The goal is achieved by the fact that the trolleys are made in the form of sections forming a continuous load-carrying platform, equipped at the margins with rollers interacting with the branches of the carrying rope and fixed on the traction rope with the possibility of rotation.

Figure 1 shows the installation for filling the grooves, a general view; Fig.215 is the same, top view; Fig. 3 is a section along A-A in Fig. 1.

A rope system with a traction winch 2, a winch 3, and a TURN1 TRAIL1 cable 4 between the branches of the driving rope 5, which forms a horizontal overpass with a sectioned cargo 6 with it, is suspended between the movable tower supports 1 installed above the pitted recess.

Next to one of the towers 1, perpendicular to the cable system, there is a movable loading device 7 with conveyor trains 8 mounted on rails, made, for example, in the form of a 30 vertical discharge loop for trains with a chute curved in the direction of movement of the load-carrying fabric 6. The sections of this fabric 6 are fastened between by means of fastening 9 and overlap each other with their transverse edges, forming a continuous groove. The sectional load-carrying canvas 6 is provided along the edges with rollers 10, resting on the branches of the driving rope 5. The sections of the blade b along the middle line are made out of two sections 11 and 12 of which are movably rotated to the sides, with nodes securing 9 sections to the tow rope 4. When the tower installation is in operation, the conveyor trains 8 bring the weight of the furnace to the loading device 7, which, in its initial position, is mounted with its groove on the cargo carrying canvas / b below it. obom at boot time. When the carriage rolls over of the conveyor train 8 on the vertical loop of the loading device 7, the weight of the mountains is poured out and flows along the chute to the load-carrying canvas 6 of the tower installation, which, as it is filled, moves at a low speed synchronously with the movement of the conveyor train carriages 4 winch work 2. After the loading is completed, the loading device is moved back from the zone of the rope aging, increasing the rotational speed of the drum of the pull winch 2, thereby increasing the speed of movement of the loaded load-carrying web b to the transportation speed. Moving the blade b occurs on the rollers 10 along the branches of the m-drive rope 5. Above the place of unloading of the rock mass, the load-carrying cloth is stopped with the b and winch 3 and they lower the branches of the ride-over rope 5 until parts of sections 11 and 12 are rotated around the hinges 13 on the attachment points 9 and will not occupy the lowest position, in which the mass of the hearth is poured in both directions from the gland into the recess. After termination of unloading, the branches of the driving rope 5 are tensioned with a winch 3 and lifted them to the extreme upper position until the complete connection of both parts 11 and 12 of the load carrying section and the formation of a continuous groove is complete. After that, the winch 2 winds the rope 4 and returns the load-carrying canvas to the loading device 7, where it is stopped and the loading device 7 is fitted along the rails, installing its chute again over the cargo-carrying canvas b. Then, the operation of loading the rock mass from the conveyor train 8 supplied to the loading device 7 is repeated. Due to the heavy loading capacity of the load-carrying fabric compared to the trolleys of the known mounted aerial cableways, as well as due to the provision of a continuous operation of transferring the rock mass from the conveyor train without intermediate dumping operations , the performance of the proposed installation is 8-10 times higher than that of known structures with a capacity of 230 t / h. The possibility of reducing the shock loads during the overload of the rock mass: on the load-carrying fabric, the simplicity, accuracy and reliability of the unloading operation increases the efficiency of the installation and allows to obtain a high total economic effect. The invention The tower installation for seeding grooves, containing movable supports with mounted on them load-carrying rope drives with two parallel branches and a traction rope, with trolleys fixed on it, in order to increase the load capacity of the installation, The trolleys are made in the form of sections that carry out the load carrying platform and are equipped with rollers interacting with the branches of the carrying cable and fixed on the cable so that they can be rotated.
