Description

Perforating machine for coal mine underground water power industry

Technical Field

The invention belongs to the field of coal mine machinery, and particularly relates to a through hole machine for repairing an underground old hole of a coal mine.

Background

After the underground coal mine gas extraction drill hole is networked for extraction, along with the effects of extraction influence and ground stress, particularly for soft coal seams, the wall of the drill hole can often displace, so that the extraction drill hole is seriously deformed or even locally collapsed, the extraction drill hole is blocked, the gas extraction concentration is quickly attenuated, the extraction effect of the drill hole is influenced, finally, the extraction drill hole which costs huge manpower, material resources and financial resources for construction is reduced into a waste hole, the gas treatment effect of the coal mine is seriously influenced, and potential safety hazards are left for the normal production of the coal mine.

Under the modern coal mine gas treatment technology, after a collapsed hole of an extraction drill hole, gas is continuously extracted after the extraction drill hole is generally encrypted in a form of a supplementary drilled hole around the collapsed hole, however, in order to ensure that no blank zone is left for extraction, the designed initial extraction drill hole is quite dense, and various deviations are generated due to condition limitation in the drilling process, so that the hole crossing phenomenon of the supplementary drilled hole often occurs, the final extraction effect of the supplementary drilled hole is greatly reduced, and the final gas treatment effect is influenced. Therefore, the technology for repairing the drilled hole to be popularized and applied is definitely proposed in thirty-two coal mine gas prevention and control released in Henan province in 2018, and the problems of hole collapse and hole blocking of the drilled hole are solved.

The invention relates to a hydraulic working machine for a mine, which is an invention patent with the application number of 2012104898950, wherein the invention discloses the hydraulic working machine which is adjustable in direction, high in equipment concentration and suitable for a narrow underground working space by using a coiled tubing technology in the petroleum industry and combining a high-pressure water jet theory in the coal mine industry. The hydraulic power working machine is characterized in that a lifting oil cylinder is arranged on a sledge-shaped base, a roller main shaft is arranged on the lifting oil cylinder, a left supporting arm, a right supporting arm and a roller wound with a flexible steel pipe are arranged on the roller main shaft, a pipe conveying device and a pipe collecting hydraulic motor are arranged on the left supporting arm and the right supporting arm, a pipe discharging hydraulic motor is arranged on the pipe conveying device, the pipe discharging hydraulic motor is in driving connection with a double-row chain wheel in the pipe conveying device, the flexible steel pipe is clamped between double-row chain wheels, a nozzle is arranged at one end of the flexible steel pipe, the other end of the flexible steel pipe is wound on the roller after passing through the pipe conveying device. When the pipe is collected, the pipe collecting hydraulic motor supplies oil, the pipe releasing hydraulic motor does not supply oil, the pipe collecting hydraulic motor drives the roller main shaft to rotate, the roller main shaft drives the roller to rotate, so that the flexible steel pipe is wound on the roller main shaft, and the pipe collecting action is finished; when the pipe is released, the pipe releasing hydraulic motor supplies oil, the pipe collecting hydraulic motor does not supply oil, the pipe releasing hydraulic motor drives the double-row chain wheel in the pipe conveying device to rotate, the double-row chain wheel drives the flexible steel pipe to feed the pipe into the drill hole through friction force, and the roller is passively reversed under the pulling of the flexible steel pipe, so that the pipe conveying action is realized.

The hydraulic power operation machine realizes the height adjustment of the pipe conveying through controlling the extension and retraction of the lifting oil cylinder. The direction adjusting mechanism is arranged between the left support arm and the roller main shaft and comprises a pinion shaft, a turbine, a worm and a hydraulic motor, the left support arm and the right support arm on the roller main shaft can be driven to rotate around the roller axis through the matching of the pinion shaft, the turbine, the worm and the hydraulic motor, and then the pipe conveying device arranged on the left support arm and the right support arm can adjust the direction around the roller axis and always keep the pipe conveying direction of the pipe conveying device consistent with the tangential direction of the roller, so that the pipe conveying device can work at different angular positions.

When the hydraulic power operation machine works, the flexible steel pipe is firstly sent into a hole blocking section in a drill hole, the high-pressure water pump station is started, high-pressure water is sprayed out through the flexible steel pipe and the spray heads at the end parts of the flexible steel pipe and acts on a slag block blocking the drill hole, the slag block is punched and broken and then flushed out of the drill hole, the drill hole is dredged, the extraction drill hole which falls into a waste hole is recycled, and the service life of the drill hole is prolonged.

In order to realize the multilayer orderly winding of the flexible steel pipes on the roller, a reciprocating shaft is arranged in a spline shaft of a main shaft of the roller, the roller rotates in the same direction and simultaneously realizes axial reciprocating motion, and the flexible steel pipes are always kept consistent with the center of a pipe conveying pipe of the pipe conveying device in the left and right directions when moving along the tangential direction of the outer circumference of the roller, so that the orderly winding of the flexible steel pipes on the roller is ensured.

The following problems are found in practical applications:

1. the roller is rotated and simultaneously moves along the axis direction of the roller main shaft by arranging the reciprocating shaft on the roller main shaft, so that the roller is limited by the large weight of the roller and the requirement on precision machining of the internal structure dimension of the roller main shaft, the phenomena of loose and disordered winding of the flexible steel pipe on the roller can be caused, and the structural reliability is poor.

2. When the inclination angle of the pipe conveying device is adjusted, the left support arm and the right support arm which are arranged on the roller main shaft are driven by the direction-adjusting hydraulic motor to rotate around the axis of the roller main shaft, and the roller main shaft does not synchronously rotate, so that the distance between a chain in the pipe conveying device and the roller is changed, and when the distance between the pipe conveying device and the roller is reduced, the flexible steel pipe between the pipe conveying device and the roller can be loosened and bent, and the orderly winding of the flexible steel pipe on the roller is influenced.

3. This hydraulic power operation machine's sledge-shaped base does not possess automatic walking and horizontal direction rotation function, need artifically or with the help of the winch to transport equipment to the operation place before using, then rotate sledge-shaped base position and just can make the play tub position of flexible steel pipe aim at the drilling, because hydraulic power operation machine fuselage weight is big, the space is narrow and small in the pit, the ground undulates unevenly, can not use large-scale instrument and equipment to remove and adjust sledge-shaped base, only rely on workman mobile device and adjustment base position, not only intensity of labour is big, and the adjustment precision is poor, inconvenient operation.
