Description

Technical Field

[0001] This invention belongs to the field of mine backfilling technology, specifically relating to a mine underground pipeline erection and installation device and its usage method. Background Technology

[0002] In the metal mine production system, the underground drainage system, along with ventilation, transportation, and power supply systems, is a core system for ensuring the safety of underground operations and maintaining production continuity. Its smooth and efficient operation directly affects the overall production efficiency of the mine and the safety of the underground working environment. As the mining depth of metal mines continues to extend downward, the underground geological environment becomes increasingly complex. On the one hand, factors such as rock seepage and groundwater recharge lead to severe scaling in the underground horizontal tunnel drainage pipes, resulting in increased drainage time, higher energy consumption, and lower efficiency. It is necessary to replace the severely scaled horizontal tunnel drainage pipes in a timely manner.

[0003] Currently, the traditional construction method of using scaffolding as a high-altitude work platform is commonly used in underground pipeline replacement construction. When erecting scaffolding, components such as uprights, horizontal bars, and scaffold boards must be assembled section by section according to the tunnel height and pipeline route. This not only consumes a large amount of steel and labor but also takes a long time. After the pipeline installation is completed, the scaffolding must be dismantled and transported, further increasing construction time and costs. This construction method is not only inefficient but also leads to a prolonged pipeline replacement period. If the drainage system is in a state of partial shutdown for an extended period, it may affect the normal production progress of the mine and even trigger a sudden increase in underground drainage pressure, adversely affecting mine production and operation. Summary of the Invention

[0004] The purpose of this invention is to provide a device for installing underground pipelines in mines, so as to solve the problem that the existing underground space in mines is limited and it is impossible to quickly replace drainage pipelines.

[0005] Another objective of this invention is to provide a method for using a pipeline installation device in underground mines.

[0006] The technical solution of the present invention is: a pipeline erection and installation device for underground mines, including a trolley, with columns symmetrically fixed on one side of the top of the trolley, and adjustable sliding rods slidably connected to the inner sides of the two columns. A hand-operated hoist is provided at the top of the sliding rod, and a support assembly is provided inside the sliding rod. The support assembly includes symmetrically arranged threaded rods, support beams, and telescopic rods. A threaded sleeve is connected between the two threaded rods. The threaded rods are detachably connected to the sliding rods. The support beams are symmetrically connected to the threaded rods, and the two telescopic rods are movably connected to the two support beams respectively.

[0007] As a further improvement of the present invention, the inner sides of the two columns are provided with sliding limiting grooves, and the sliding rod is slidably connected in the sliding limiting grooves.

[0008] As a further improvement of the present invention, the sliding rod is provided with multiple limiting holes, and the column is provided with multiple mounting holes, and the limiting holes and mounting holes are connected by positioning pins.

[0009] As a further improvement of the present invention, a plug is provided on the outside of the threaded rod, and the plug is respectively inserted into the corresponding limiting hole.

[0010] As a further improvement of the present invention, a hanging rod is provided at the top of the sliding rod, and a hand-operated hoist is connected to the hanging rod.

[0011] As a further improvement of the present invention, both support beams are provided with grooves, and the top of the telescopic rod is provided with a slider, which is slidably connected in the groove, and the other end of the telescopic rod is in contact with the ground.

[0012] As a further improvement of the present invention, a fixing rod is provided between the two support beams to increase the support effect.

[0013] As a further improvement of the present invention, the bottom of the trolley is connected to a connecting shaft via a sleeve, and wheels are connected to both sides of the connecting shaft.

[0014] As a further improvement of the present invention, the trolley has a slot on the side away from the column, and multiple counterweights are provided in the slot.

[0015] A method for using a pipeline installation device in underground mines includes the following steps: A. Place a spare pipe on the trolley, move the trolley to the pipe installation location using wheels, fix the wheels with rails and wooden blocks, extend the sliding rod to the required height, and fix the sliding rod to the column by passing the positioning pin through the positioning hole and the limiting hole in sequence. Place a suitable counterweight in the slot of the trolley to prevent tipping. B. Suspend the pipe to be installed on the hand chain hoist. Raise the pipe to the highest position by pulling the hand chain hoist. First, extend the telescopic rod to the appropriate height. Then, insert the slider into the slide groove so that the telescopic rod raises the support beam to a stable state. Control the hand chain hoist to lower the pipe smoothly and place the pipe on the support beams on both sides. C. The pipe is pulled by a hand chain hoist to roll on the support beam. The staff adjusts the telescopic rod to lift the support beam and tilt it counterclockwise so that the support beam contacts the installation position. Finally, the hand chain hoist is controlled to roll the pipe to the installation position. D. First, the staff will spot weld the replacement pipes to fix them in place, completing the initial fixation. Then, a professional welder will perform the welding to complete the final pipe installation.

[0016] The beneficial effects of this invention are: 1. This invention combines a sliding rod, a hand-operated hoist, and a support assembly, so that when replacing or installing pipes, there is no need to build additional scaffolding. Only a small number of workers are required to complete the installation and transportation of pipes, which effectively improves the work efficiency of workers and greatly reduces the workload.

[0017] 2. The present invention also enables the installation and transportation of pipelines by using a support component and a threaded rod in combination, and by using a support beam that can rotate on the threaded rod. This facilitates the sliding of the pipeline to the required installation position, simplifies the installation process, avoids the dangers of manually carrying pipelines up and down scaffolding, protects the safety of workers, and improves work efficiency.

[0018] 3. This invention relies on the wheels at the bottom of the trolley. By using different wheel types, it can be transported on the track in the tunnel, or directly in the tunnel. It can also be transported and installed in places without tracks, making it easy to adapt to various terrains in the tunnel and improving the applicability of the parts transportation.

[0019] 4. This invention has a simple structure and is convenient for pipeline installation. By using a hand-operated hoist to lift the pipeline, it greatly eliminates safety risks, improves work efficiency, and reduces labor intensity. It has strong practicality and broad prospects for promotion and application. Attached Figure Description
