Description

I The invention relates to lifting devices used for supplying bulk materials from storehouses, receiving equipment of the process equipment or as an intrashop vehicle. A lift is known, which includes curved guides and a carriage with a capacity associated with a cable drive lj. However, this elevator is characterized by the impossibility of a more extensive development of horizontal sections of the route for the purpose of loading and unloading at several points. In addition, it has a four-thread scheme of guides (two external and two internal guides), which creates difficulties in manufacturing and installation and does not exclude jamming of the trolley rolls in the guides. The closest to the invention to the technical essence and the achieved result is a lift that includes guides with horizontal and vertical sections, a trolley with a container for bulk materials, moving along cable guides and deflecting blocks for working and hauling ropes mounted on curves of the road 21. However, the limelift takes the load only at one loading point, its structure does not allow arranging the lower horizontal section of the route with several consecutive loading points, besides, it is possible that the cart is wedged in curved sections. The purpose of the invention is to expand the technological capabilities and increase the reliability of work by eliminating jamming of the trolley in the rails. The goal is achieved by the fact that in a lift, including guides with horizontal and vertical sections, a trolley with a capacity for bulk materials, moving along guiding rope drives and deflecting blocks for working and hauling ropes, are mounted on curved sections of the route In the loading area, the additional parts are provided with a horizontal section, while the trolley is made in the type 732 of two parallel threads, each of which is made of me- dium with the help of carriage plates, with cm on average parallel filaments carriages mounted container for bulk materials, and extreme karetki.parallelnyh filaments bonded together, and each pair of cross members associated crossmembers carriages provided with two cross pieces mounted on leveling blocks, and two pairs of guide units for respective ropes. In addition, the deflecting units are located along the path in two rows to the axis of their grooves and coincide in plan with the axes of the grooves of the guides. blocks of carriages. FIG. 1 shows a lift with a trolley located at the top in the extreme right position, a general view; in fig. 2 - lift, plan; in fig. 3 - trolley with capacity, side view; in fig. 4 .- view A in FIG. 3; in fig. 5 is a section BB in FIG. one; in fig. 6 is a sectional view BB in FIG. 4. The elevator contains two parallel I-profile profile guides, having lower horizontal, vertical, and upper horizontal sections articulated to each other along radius curves. In the horizontal sections, the guides are suspended in U-shaped supports 2, the vertical and curved sections are fixed to the metalwork of the 3 mines. On the rails 1, a trolley 4 is installed, by means of which the cargo is transported from the loading points at the lower level to the unloading points at the higher level. The carriage 4 consists of carriages 5, the rollers 6 of which rest on the guides 1. The carriages 5 are arranged with a certain pitch, are jointly interconnected by plates 7 and form two parallel threads, while the extreme carriages 5 are connected by cross-pieces 8 and 9. On the front cross-bar 8 there are two equalizing blocks 10 and 11 and two pairs of guide blocks 12 and 13 in which the working rope 14 moves the trolley in the forward direction. With the rear cross member 9, a pull rope 15 is connected to move the trolley in the opposite direction. In the opening of the trolley 4 on the middle carriages 5, a container 17 for the bulk material is hinged on the fingers 16, maintaining the horizontal position throughout the movement, since the center of the bone section is located below the axis of the suspension. On the upper platform, behind the guides 1, a lift drive is placed, consisting of a drum 18, driven by the electric motor 19 through a gearbox 20. On the electric shaft, there is a shoe brake installed on the shaft. On drum 18, working 14 is placed, opposite the diameter of the side with pull 15 ropes, which are placed in the same streams. When the working rope 1A is being wound, the pull rope 15 is pulled out from the foot of the jack 18 and vice versa. The work rope 14 moves the carriage 4c with the loaded container 17 from any of the loading points to the unloading points. The grab of the cart 4 to the working rope 14 is produced; it is driven by two equalizing blocks 1 and 11. The pull rope 15 captures i the cart 4 from the opposite side through two equalizing blocks 21 and 22. This eliminates the distortion and jamming of the cart 4 while moving; An open rope 15 displaces the movement of the cart 4 with an empty tank 17 from the loading point to the loading point. ; On the curved sections of the track from the side of the concavity, there are guide blocks 23, on which worker 14 and pull ropes 15 rest. Deviation blocks 23 are installed on the left and right sides of the following directions: 1 for the trolley 4 running away from the trolley 4 and for the rope running over the trolley 4 branches. The second ends of the worker 14: and the rest 15 ropes at the ends of the guides 1 are secured to the metal structure through a spring 24 of sufficient rigidity and a tension screw 25 The elevator works as follows. The elevator is equipped with a centralized address address system. On the lower floor there is a control panel 26, from which the addresses of the loading and unloading station addresses are set by pressing the corresponding buttons. After filling the container 17 with bulk material, the cable drive electric motor 19 is automatically switched on. The pull rope 15 is unwound from the drum 18, while 734 working rope 14 is wound onto it, occupying the vacated grooves. The working rope 14, which bends the head block 27, the deflecting blocks 23 and the passage blocks of the trolley 4, moves the latter with a capacity of 17 along the guide rails 1. The pull rope 15, which remains in a stretched state, follows the trolley 4. When moving on a horizontal Both branches of the working 14 and both branches of the pull 15 ropes occupy a horizontal position, as well as the sama trolley 4. When the trolley 4 approaches the lower curve between the direction of movement of the front cross member 8 and the branches of the working rope 14, a divergence angle is formed, insignificant in magnitude There are differences on the curves of several deflecting blocks 23. Regardless of the deviation of the branches of the ropes in the vertical plane, the worker 14 and the retractable 15 ropes enter their equalizing blocks strictly along the axis of the groove, since each equalizing block has its own pair of guide blocks 12 and 13 , 28 and 29, which also fulfill the second purpose: during the forward movement of the carriage 4, the front pair of guide blocks 12 and 13 remove the rope from the -. clone blocks 23, and rear pairs of guide blocks 28 and 29 lay the branches of the OTT.SENSIVE rope 15 on the deflecting blocks 23. The axes of the deflecting blocks 23 of the route coincide in plan with the axes of the yush, their blocks 12 and 13, 28 and 29, the carriages 4, but the deflecting units 23 have a somewhat larger width for a safe stowage. On them the rope descending from the drum 18 when the carriage 4 moves. trailing paths .23 as they pass relative to each other are set to a minimum of 10 mm. The vertical portion of the path of the cart 4 passes suspended on the ropes behind the equalizing blocks 10 and 11, to limit the oscillations on the guide tracks, counter-tires 30 are arranged, ensuring the passage of the rollers 6 of the cart 4 with a small gap. When the trolley 4 enters the upper curve, the driving branches of the working rope 14, resting on the upper curve deflecting blocks 23, are formed by directing the movement of the front puller I 1 of the rank 8 of the trolley 4 to the opposite angle, the angle is negligible, making it difficult for the trolley 4 to pass the curve the plot is not created. With the " approach of the cart 4 to the predetermined point of discharge, the addressing system is triggered; the cart 4 stops at the desired place. After the tank 77 is unloaded, the drum 18 obtains the opposite rotation, the carriage 4 reverses by means of a pull rope 15. The working cable 14 is unrolled from the drum 18, follows the carriage 4 and is placed on the deflecting units 23. The proposed lift is advantageously applied to transport bulk materials along a complex curved path, alternately from several bunkers or aggregates combined into one group, into another group of equipment installed at a higher level (crushers, mills, dried and, mixers, etc.) ..
