SU752010A1 - Set for deepening vertical mine shafts - Google Patents

Description

one

The invention relates to mining equipment, which is widely used in the excavation of vertical shafts, to open and prepare new horizons and to reconstruct existing 5 mines.

Bundling complexes for driving vertical shafts are known, consisting of a bucket, a hitch and a guide frame.

The guide frame in the complexes with a non-tilting bucket can be structurally designed so that when using the same frame size, the type of guide devices can be changed depending on the type of conductors. This replacement allows the guide frame to move along only one type of conductor: either cable or rigid, 1.

The disadvantage of this complex is 20 that it can provide movement of the guide frame either only along the cable or only along rigid conductors, and only one specific rail type, and are intended for use on the surface in a short section of the order of 10. -15 M within the copra, i.e., from the zero frame to the unloading device during the normal sinking of a new trunk.

Also known is a badge complex intended for the sinking of vertical shafts, including a self-tipping bucket, a hitch, a guide frame, a regimental guide socket, an unloading box, rope and rigid conductors {2.

In this complex, the scaffold is suspended on a trailer device to the lifting rope and moves along the trunk also together with a vertically movable frame, which with the help of guide devices moves along two guide ropes.

When deepening vertical shafts from the surface, one usually uses the detachment of one of the operational lifts, which can be dismantled for the time of the hollow of the trunk, to accommodate the tub and other tunneling equipment.

The disadvantage of this complex is that, in order to be able to approach the bucket to the bottom of the recessed shaft, it is necessary to simultaneously with the excavation works on the trunk dredging after the bottom is pushed in full or in part to carry out complex works on the erection of rigid conductors in the recessed parts of the trunk to allow movement on them

The guide frame, which greatly complicates the work and reduces the rate of dimple.

The aim of the invention is to simplify the mining operations, increase the productivity of the tunnel lift, improve the technological schemes and increase the depth of the shaft shafts.

This goal is achieved by the fact that the complex is equipped with an additional guide socket, is placed at the border of the reinforced and unreinforced sections of the recessed shaft, and the guide frame is made with dual guide devices in the form of sleeve guides and shoes with the possibility of simultaneous movement along the cable and rigid guides and skis, while the bell has tapering curvilinear guides in contact with the skis of the guide frame to stabilize its movement.

 FIG. Figure 1 shows a complex for dredging the trunk at the moment of loading the tub at the bottom of the barrel, general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 - guide frame; in fig. 5 and 6 are structural elements of each set of dual guiding devices; in fig. 7- additional guide socket. The plow complex contains a pail 1, which is attached to the overhead rope with the help of a hitch, a regimental guide socket 2 to pivot the pouch when it approaches the bottom of the trunk and fix it in a certain position in the guide frame 3 for joint movement along the trunk and providing self-unloading The tubs on the discharge section 4, with the guide frame 3 having four sets of the proposed double guide devices 5 and an additional guide socket 6. The rigid 7 and cable 8 conductors are located in the core the existing (reinforced) part of the trunk, and the cable conductors in the recessed part of the trunk.

The guide frame 3 consists of a frame 9, a detachable assembly of sleeve bushings 10, the body and cover of which in this case is designed as a ski guide, a removable shoe 11 which is attached to the assembly of guide devices 5 by bolting, and a ski guide 12 .

The dual guide device 5 is made as a single welded assembly and is attached by a welded joint to the vertical stand of the frame 9 of the guide frame 3. The detachment of the sleeve bush assembly 10 and the removability of the shoe 11 are necessitated by the need to replace these rubbing parts of the guide devices 5 during operation . The additional guide socket 6 consists of a cylindrical body 13 having conical wide beams in the upper and lower parts of the socket 6.

On the inner walls of the cylindrical part of the bell 6, two gifts of diametrically arranged tapering guide curves 14 are welded.

The complex works as follows.

After unloading on the special section 4 located in the scraper on the surface, the tub 1 starts to move downward into the bottom of the recessed shaft, where within the existing (reinforced) part of the barrel the guide frame 3 with four sets of dual guide devices 5 moves simultaneously cable and rigid conductors. This is achieved by contacting the four shoes 11 with two rigid conductors 7, which can be rail, box, wood, etc., and four stub tracks 10 with two cable conductors 8, laid along the entire length of the trunk. After the bucket 1 enters the recessed (unreinforced) part of the barrel, the guide devices 5 of the frame 3 move only along two cable conductors 8, which is ensured by contacting four sleeve guides 10 with them.

When the tub 1 is moving upwards from the bottom hole within the unreinforced portion of the barrel, the guide devices 5 of the frame 3 move only along two cable conductors 8.

When the bucket approaches the existing (reinforced) trunk section, a reliable smooth transition from the guide frame movement with the tub 1 from the bottom upwards only along the cable conductors 8 to simultaneous movement along the cable 8 and rigid 7 conductors within the existing (reinforced) part of the trunk is provided by contacting the guides curves 14 in the additional guide flap 6 with the guide skis of the guide devices 5 of the frame 3. The spout 6 is installed in the place where the rigid conductors 7 begin. equalizing skis on guide devices 5 at a reduced speed is caught by the tapering curves 14 of the additional guide socket 6, its movement is stabilized, the swinging decreases to a value that provides the main entrance of the shoes 11 to the rigid conductors 7, and the 7 with frame 3 continues to move upwards simultaneously along cable 8 and rigid 7 conductors at increased speed, then enters the unloading device on the surface, where the tank 1 itself is unloaded on de 4.

In the zone of the unloading device, the guide frame 3 is located only on the cable n-conductors 8, which ensures that the commercially available field 4 is used for unloading.

The use of the complex, which has dual guide devices on the guide frame and an additional guide socket, makes it possible to place the tunnels of the increased capacity in the cramped conditions of the existing part of the trunk, cluttered with executions, and to simplify the mining works in the deepened part of the trunk in connection with the fact that there is no need to perform a constant reinforcement following the advance of the trunk.

Thus, the complex makes it possible to increase the productivity of the tunnel lift, to complete technological schemes, to increase the rate of dredging of mine shafts by about 1.5 times compared to the performance of these works using known equipment.
