Abstract

The invention relates to the mining industry and is intended to guide the stands in vertical shafts with frontal conductors. The goal is to increase the reliability of the equipment, as well as to expand the scope of use by allowing the use of barriers with light barrier doors in barrels. The equipment includes: the metal structure of the trunk reinforcement ,, composite conductors (П) 1, the fixation mechanism, the upper and lower JtL horizontal directions of the body 7. At the same time, П 1 have movable pieces 3 joined with fixed part П 1 by means of bevelled ends and installed in the area of the security doors of the reception area. On the non-working side of the segments 3, the brackets 5 with paired rollers 6 at the ends supported by the guides 7 are hinged. The transmissions of the movement of these segments 3 are executed in the form of slider-and-slide mechanisms. The arm 8 of the latter is pivotally connected with the drive 4 and the metalwork of the reinforcement, and the slider with the cut 3. One of the brackets 5 is attached to the piece 3 with the possibility of movement along its axis and has an elastic element for pressing the rollers 6 to the guide 7. For carrying out - unloading operations of the cage is installed in the area of the receiving site. The locking mechanism separates the segment 3 and the stationary fixed P1. The actuator 4 is turned on, which, acting on the slingshot 8, retracts segment 3 to the side, freeing the passage into the cage for people and cargo. 1 hp f-ly, 2 ill. (L c: 4 a co od c 1C fi.

Description

The invention relates to the mining industry, is intended to guide the stands in vertical shafts with -bout conductors, in particular to ensure the maximum speed of their movement in areas of intermediate horizons.

 The purpose of the invention is to increase the reliability of equipment J as well as expand the scope of use by allowing barrels to be used with light and barrier-type safety doors.

Fig. 1 shows a general view of the equipment (the movable segment of the conductor of the right section is retracted to the side) in Fig. 2 - the same, side view.

The equipment of the mine shaft of the glue pot in the area of the receiving site consists of conductor 1, fixed on the horizontal balts 2 of the copra machine or. interface horizon with the barrel and having a movable segment 3 of the actuator 4 and the locking mechanism (not shown), the movable segment 3 of the conductor. Equipped w-mounted on it with the help of brackets 5 rollers 6 j resting on the horizontal guides 7, which can be fixed on the horizontal Beams The brackets 5 are spaced apart by the height of the movable segment 3 and two rollers 6 are mounted on each of them. Moving the conductor segment 3 is carried out j, for example, using the streets 8, hinged:.) on the beam 2. KopoTKHii lever connected to the rod of the hydraulic shaft of the drive unit 4, and the second end is provided with a roller or a slider 9, which interacts with the movable length 3 of the conductor and moves along its longitudinal axis in the guides 10. The brackets 5 are hinged on the conductor, one of them can move along the longitudinal axis of the conductor, for which there is a groove in the conductor. The movable bracket is connected to the conductor through an elastic element, for example, a spring 11, which is installed between the bracket and the metal structure of the reinforcement of the movable segment of the conductor. The stiffness of the elastic element must be chosen so that the load from the mass of the moving conductor is distributed

approximately evenly between the upper and lower rollers. As a fixing mechanism, any of the known mechanisms can be applied, which can be controlled either by a lever or remotely using a hydraulic or pneumatic actuator.

During the operation of the lifting installation, the movable sections of the 3 conductors are in the working position, ensuring the movement of the vessels throughout the entire turn, Including in the sections of the weft horizons, To carry out loading and unloading operations, the stand is installed The receiving platform, which is then actuated by a locking mechanism separating the movable segment 3 of the conductor from the fixed stationary 1, activates the actuator 4, which, acting on the short lever of the link 8, retracts the movable segment 3 of the conductor to one hundred ONU, releasing the passage in the cage for people and goods. After the end of the loading and unloading operations, W-1J, segment 3 of the conductor returns to its place and. is fixed. In order to ensure the safety of the operation, the device is equipped with protections for switching on the drives of the lifting machine, the movable piece of wire and the fixing device.
