Abstract
Description
Technical Field
[0001] This utility model relates to underground coal mine roadways for transporting coal mine machinery and mining equipment, specifically to an underground coal mine turning and hoisting structure. Background Technology
[0002] Coal mine machinery and equipment are first transported from the auxiliary shaft to the underground roadways, and then transported to the site of use by vehicles on the surface tracks of the underground roadways. The underground roadways of coal mines have a surface, ceiling, and side walls. Sleepers are laid on the surface, and tracks are laid on the sleepers. Because the cage size in the auxiliary shaft is relatively small, the components of large coal mine machinery and equipment must be smaller than the cage size to be allowed to enter the mine. To meet the cage size requirements, large equipment must be disassembled into its smallest components before being placed in the mine. After all components are in the mine, they are transported to the site of use, where they are assembled and installed using cranes and other equipment. Installation at the site of use would disrupt other normal production tasks.
[0003] Some underground coal mine work surfaces have special requirements for the direction of vehicles carrying equipment components. Therefore, some underground vehicles carrying equipment need to be transported to the shunting line to change direction before being transported to the required location. This method increases the operation time and transportation distance, and increases the workload of underground transportation. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a coal mine underground turning and hoisting structure that can complete the lifting, dismantling or assembly of coal mine machinery and mining equipment in the roadway area, and at the same time complete the task of adjusting the direction of transport vehicles on the track.
[0005] To solve the above-mentioned technical problems, the present invention provides a coal mine underground turning and hoisting structure, characterized in that: it includes six hydraulic cylinders fixed to the tunnel ceiling and arranged in pairs, with the piston rods of the front and rear pairs of hydraulic cylinders facing each other; each hydraulic cylinder has a fixed pulley frame fixed to the end of its piston rod, a turning pulley frame fixed to the tunnel ceiling along the extension direction of the piston rod, and a rope fixing plate fixed to the tunnel ceiling on one side between the turning pulley frame and the fixed pulley frame; the fixed pulley frame is equipped with a fixed pulley, the turning pulley frame is equipped with a turning pulley, and a hoisting rope is fixed to the rope fixing plate; the hoisting rope passes sequentially around the fixed pulley and the turning pulley, and a hook is attached to the end of the hoisting rope; the front and rear hydraulic cylinders are located directly above the tunnel surface track, the front right and rear right hydraulic cylinders are located to the right of the front and rear hydraulic cylinders respectively, and the front left and rear left hydraulic cylinders are located to the left of the front and rear hydraulic cylinders respectively.
[0006] As an improvement of this utility model, the fixed pulley frame has upper and lower pressure plates, the fixed pulley is mounted between the upper and lower pressure plates through a first pulley shaft, the ends of the upper and lower pressure plates are mounted on the piston rod of the hydraulic cylinder through pins, and limit baffles are respectively installed between the upper and lower pressure plates located on both sides of the pins.
[0007] As a further improvement of this utility model, the steering pulley frame includes a mounting frame and a swing frame; the mounting frame has a rectangular top plate for fixing to the roof of the tunnel, and a rectangular frame formed by front and rear end plates and left and right side plates is fixed to the bottom of the top plate; the swing frame includes a cable guide rotatably mounted between the front and rear end plates, and a strip groove with a width equal to the inner diameter of the cable guide is opened at the bottom of the cable guide; downwardly extending pulley mounting plates are fixed at the openings on the left and right sides of the strip groove, and the steering pulley is mounted between the left and right pulley mounting plates through a second pulley shaft.
[0008] Furthermore, there is a gap between the pulley mounting plates on the left and right sides and the side plates on the left and right sides, and the pulley mounting plates can swing left and right by 5°-10° with the bobbin as the axis.
[0009] Furthermore, notches are provided on the left and right side plates at positions corresponding to the second pulley shaft.
[0010] This utility model has the following beneficial technical effects: 1. Located in an underground roadway, the assembly or disassembly of coal mine machinery and mining equipment can be completed within this roadway area without affecting other normal production tasks; 2. This utility model consists of only 6 hydraulic cylinders, fixed pulleys, steering pulleys, lifting ropes, and hooks, etc., with a simple structure. Furthermore, the above-mentioned equipment and components are installed on the roadway ceiling, occupying little space and not affecting the normal passage of rail vehicles. When disassembling or assembling the equipment, the corresponding components can be lifted by the hooks on the 6 hydraulic cylinders, allowing operators to perform the necessary tasks. The following are the main features of this invention: 1. It can be used for assembly or disassembly tasks; 2. The hooks on the six hydraulic cylinders in this invention can be used in combination to turn the direction of vehicles on the roadway surface track; 3. The pulley mounting plate in this invention can swing left and right by 5°-10° with the cable drum as the axis. With the above technical features, when the hoisting rope passes through the cable drum and around the steering pulley, the phenomenon of the hoisting rope getting stuck can be avoided as much as possible, which is conducive to the smooth passage of the hoisting rope through the steering pulley; 4. The left and right side plates are respectively provided with notches at the positions corresponding to the second pulley shaft. With the above technical features, it is convenient to disassemble and assemble the second pulley shaft. Attached Figure Description
