Description

Technical Field

[0001] This utility model belongs to the field of mine filling technology, specifically relating to a mine underground pipeline erection and installation device. 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. Utility Model Content

[0004] The purpose of this utility model 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] The technical solution of this utility model 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 on 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.

[0006] As a further improvement of this utility model, 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.

[0007] As a further improvement of this utility model, the sliding rod is provided with multiple limiting holes, and the column is provided with multiple mounting holes. The limiting holes and the mounting holes are connected by positioning pins.

[0008] As a further improvement of this utility model, a plug is provided on the outside of the threaded rod, and the plug is inserted into the corresponding limiting hole.

[0009] As a further improvement of this utility model, a hanging rod is provided at the top of the sliding rod, and the hand-operated hoist is connected to the hanging rod.

Columns 5 are symmetrically fixed to one side of the top of the trolley 1. Adjustable sliding rods 6 are slidably connected to the inner sides of the two columns 5. A hand-operated hoist 10 is installed at the top of the sliding rod 6. A support assembly is located inside the sliding rod 6. The support assembly includes symmetrically arranged threaded rods 12, support beams 15, and telescopic rods 13. A threaded sleeve 17 connects the two threaded rods 12. The threaded rods 12 are detachably connected to the sliding rods 6. The support beams 15 are symmetrically connected to the threaded rods 12. The two telescopic rods 13 are movably connected to the two support beams 15 respectively.

[0022] The inner sides of the two columns 5 are provided with sliding limit grooves 11, and the sliding rod 6 is slidably connected in the sliding limit grooves 11.

[0023] Multiple limiting holes 8 are provided through the sliding rod 6, and multiple mounting holes 7 are provided through the column 5. The limiting holes 8 and the mounting holes 7 are connected by positioning pins 9.

[0024] The threaded rod 12 is provided with a plug 20 on the outside, and the plug 20 is inserted into the corresponding limiting hole 8.

[0025] The top of the sliding rod 6 is provided with a hanging rod 14, and the hand chain hoist 10 is connected to the hanging rod 14.

[0026] Both support beams 15 are provided with grooves 18, and the top of the telescopic rod 13 is provided with a slider 19. The slider 19 is slidably connected in the groove 18, and the other end of the telescopic rod 13 is in contact with the ground.

[0027] A fixing rod 16 is provided between the two supporting beams 15.

[0028] The bottom of the trolley 1 is connected to a coupling 3 via a sleeve, and wheels 2 are connected to both sides of the coupling 3.

[0029] The trolley 1 has a slot on the side away from the column 5, and multiple counterweights 4 are installed in the slot to prevent the trolley 1 from tipping over due to excessive weight on the pipe-laying side.

[0030] A method for using a pipeline installation device in underground mines includes the following steps: A. Place a spare pipe on the trolley 1, move the trolley 1 to the pipe installation location using the wheels 2, fix the wheels 2 with the track chocks, extend the sliding rod 6 to the required height, and fix the sliding rod 6 to the column 5 by passing the positioning pin 9 through the positioning hole 7 and the limiting hole 8 in sequence. Place a suitable counterweight 4 in the slot of the trolley 1 to prevent tipping. B. Suspend the pipe to be installed on the hand chain hoist 10, and lift the pipe to the highest position by pulling the hand chain hoist 10.
