Description

Technical Field

[0001] The present invention belongs to the field of mine construction machinery, and specifically relates to a mine hydraulic suspension lifting device, which is applicable to the disassembly and assembly of hydraulic supports in coal mines, and is also applicable to the disassembly, assembly and loading / unloading of other fully-mechanized mining equipment (such as shearers, conveyors, transfer machines). Background Art

[0002] At present, the support of fully-mechanized coal mining faces in China has basically replaced the traditional support method with hydraulic supports. The use of hydraulic supports, shearers, and large-scale scraper conveyors has greatly improved labor productivity. However, the installation of these devices has always been a difficult problem in coal mine production, and there have been many drawbacks such as long installation cycles, high personnel requirements, high labor intensity, low work efficiency, and many potential safety hazards.

[0003] The patent application with publication number CN110127556A proposes a mine fully-mechanized mining equipment assembly and disassembly lifting device, which includes two parallel and juxtaposed bases. A bottom frame is fixedly arranged on each base. Along the direction of the bottom frame, a number of column sockets are fixedly arranged in the middle of its interior. A hydraulic column is fixedly arranged upright in the column socket. A top plate is fixedly connected to the piston top of the hydraulic column. Hanging pulleys are fixedly arranged on both sides of the top plate. Along the direction of the bottom frame, hydraulic cylinders with opposite directions are fixedly arranged on both sides of its interior. The piston top of the hydraulic cylinder is fixedly connected with a pulling wheel and a guiding wheel. One end of a steel wire rope is connected to the pulling wheel, and the other end of the steel wire rope is wound through the guiding wheel to the hanging pulley at the top plate and then hangs down. The lower end of the steel wire rope is connected with a hook. Its disadvantages are as follows: the hydraulic column is fixedly arranged, and the lifting part can only lift and cannot move. Due to the different shapes of the lifting points of different workpieces, it brings many inconveniences to the disassembly, assembly and loading / unloading of fully-mechanized mining equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a mine hydraulic suspension lifting device, which can solve the shortcoming of mechanized installation and withdrawal in fully-mechanized mining faces. The lifting part can not only lift but also move independently, and is suitable for handling various components with different lengths and sizes.

[0005] The technical solution of the present invention is as follows:

[0006] A mine-used hydraulic suspension type lifting device. Two groups of parallel I-beams are hoisted horizontally through the I-beam lifting duckbills on them. Walking suspension rails are respectively arranged at the bottoms of the I-beams. A longitudinal translation frame is installed at the bottom of the I-beams through the walking suspension rails. Two longitudinal translation frames are installed at the bottom of each group of I-beams. A transverse translation frame is arranged on the longitudinal translation frame. The transverse translation frame is in sliding fit with the longitudinal translation frame. Each longitudinal translation frame is connected with the transverse translation frame through a transverse movement cylinder installed on it. The longitudinal translation frame makes longitudinal translation along the I-beam under the action of power, and the transverse translation frame makes transverse translation along the longitudinal translation frame under the action of power.

[0007] For the mine-used hydraulic suspension type lifting device described above, a passage for the single-track hoist to pass through is left between the two groups of I-beams, and a single-track hoist is arranged at the passage.

[0008] For the mine-used hydraulic suspension type lifting device described above, motor brackets and power unit brackets are arranged on both sides of the longitudinal translation frame. An explosion-proof motor is installed on the motor bracket, and a cycloidal pinwheel speed reducer is installed on the power unit bracket. The output end of the explosion-proof motor is connected with the cycloidal pinwheel speed reducer through a chain. The output end of the cycloidal pinwheel speed reducer is connected with a walking wheel through a chain. The walking wheel is installed on a walking wheel frame through a walking wheel shaft. The walking wheel meshes with a roller chain sprocket. The two roller chain sprockets are connected through a roller chain. The roller chain sprockets are installed on both sides of the longitudinal translation frame. Driven by the explosion-proof motor and the cycloidal pinwheel speed reducer, the longitudinal translation frame and the transverse translation frame on it make longitudinal translation along the I-beam.

[0009] For the mine-used hydraulic suspension type lifting device described above, a guiding heptagonal pulley, a main lifting cylinder, a guiding pentagonal pulley, and a chain gripper are arranged on the transverse translation frame. A lifting chain is successively wound around the chain gripper, the horizontally arranged guiding heptagonal pulley, and the vertically arranged guiding pentagonal pulley and led vertically to the lower part of the longitudinal translation frame. A lifting hook for hanging heavy objects is installed at the lower end of the lifting chain. The extending end of the main lifting cylinder is connected with the upper end of the lifting chain of the chain gripper.

[0010] For the mine-used hydraulic suspension type lifting device described above, the guiding pentagonal pulley is installed on a guiding pentagonal pulley frame through a guiding pentagonal pulley shaft.

[0011] For the mine-used hydraulic suspension type lifting device described above, a remote control receiver is installed at the bottom of the longitudinal translation frame. The remote control receiver is connected with the control part of the power.

[0012] For the mine-used hydraulic suspension type lifting device described above, the remote control receiver is an explosion-proof and intrinsically safe type remote control receiver, and the corresponding remote control transmitter is a mine-used intrinsically safe type remote control transmitter.

[0013] The design concept of the present invention is:

[0014] The present invention mainly consists of a power unit, walking wheels, lifting chains, guiding heptagonal pulleys, guiding pentagonal pulleys (for redirecting and swinging), lifting hooks, main lifting cylinders, transverse movement cylinders, etc. It can move freely back and forth on the I-beam track, has the characteristic of a large internal limited space, sets up an independent walking and lifting module, realizes the function of flexible adjustment of the longitudinal length, meets the handling of extra-long parts, realizes the translation of the scattered parts of the top beam and the tail beam, and meets the technological requirements of special assembly and disassembly brackets. The 4 groups of independent longitudinal and transverse translation frames, 4 independent lifting hooks, and 4 sets of power units are all composed of a hydraulic cylinder-chain-sprocket group, meeting the requirements of lifting power and lifting stroke. The power unit adopts the principle of the telescopic thrust of the hydraulic cylinder and the increased stroke of the pulley group to complete the lifting, disassembly, and assembly work of the hydraulic support and the disassembly and assembly work of the "three machines".

[0015] The advantages and beneficial effects of the present invention are as follows:

[0017] 2. The lifting device of the present invention is provided with 4 longitudinal and transverse translation frames and a walking suspension track. The 4 longitudinal and transverse translation frames and the walking suspension track are assembled onto the lifting platform at a low position in the chamber after entering the well. The lifting platform raises the longitudinal and transverse translation frames or the lifting track to a suitable height (adjustable), and anchors are fixed on the roof by drilling holes in the roof. The whole process does not require relying on roof lifting tools.
