Description

Technical Field

[0001] This invention belongs to the field of coal mine safety production technology. Specifically, it relates to a device that pushes a gas extraction pipe into a gas extraction borehole and also serves as a drilling screen. Background Technology

[0002] Coal resources are one of my country's important energy resources. For coal and gas outburst and high-gas mines, coal seam gas extraction is essential during the coal mining process. Gas extraction can not only reduce the possibility of gas disasters, but also develop and utilize gas resources, turning harm into benefit.

[0003] In coal seam gas drainage operations, constructing drainage boreholes and inserting gas drainage pipes is a crucial preliminary step. However, as the length of the gas drainage pipe increases during insertion, the friction between it and the borehole wall also increases, making insertion increasingly difficult. Furthermore, to prevent the gas drainage pipe from falling out of the borehole, multiple people are usually required to complete the task. The gas drainage pipe inserted into the borehole consists of two parts: one with perforated surfaces and the other without. The section without perforated surfaces is used as a sealing section of the borehole, while the section with perforated surfaces is used to prevent borehole collapse and blockage, and also to utilize the perforated surfaces for gas drainage. The section with perforated surfaces is usually a custom-made product, therefore its perforated section length is fixed. However, when different screen hole lengths of gas extraction pipes are required on-site, manual drilling is necessary. This increases operating costs and prevents the adjustment of the screen hole length in real-time. Therefore, it is necessary to develop a device that can both push the extraction pipe into the gas extraction borehole and drill for screen holes. Summary of the Invention

[0004] The purpose of this invention is to provide a device that is simple in structure, easy to operate, and allows for adjustment of the screen hole section length of the gas extraction pipe. This device pushes the extraction pipe into the gas extraction borehole and also drills for screen holes. By setting corresponding punches on the corresponding punching wheel to punch holes in the gas extraction pipe, and when the gas extraction pipe reaches the required screen hole section length, the punches are removed and the gas extraction pipe is continued to be transported, thereby controlling the screen hole section length of the gas extraction pipe and improving the applicability of the device.

The drilling assembly includes at least one set of upper drilling wheels 3 and lower drilling wheels 4 arranged vertically opposite each other, and at least one set of left drilling wheels 5 and right drilling wheels 6 arranged horizontally opposite each other. The upper drilling wheels 3 and lower drilling wheels 4 are arranged horizontally, while the left drilling wheels 5 and right drilling wheels 6 are arranged vertically. Several first drilling spikes 7 are detachably mounted on the outer circumference of the upper drilling wheels 3 and lower drilling wheels 4. Several second drilling spikes 8 are detachably mounted on the outer circumference of the left and right opening wheels. During operation, the front ends of the left booster assembly 41 and the right booster assembly 42 are aligned with the gas extraction hole. The gas extraction pipe is placed between the left booster assembly 41 and the right booster assembly 42 and is conveyed into the gas extraction hole from back to front. During the conveying process, the drilling assembly drills screen holes on the gas extraction pipe. When the gas extraction pipe reaches the required screen hole section length, the first drilling spike 7 and the second drilling spike 8 are removed. Then the gas extraction pipe is conveyed until it is completely inserted into the gas extraction hole.

[0029] The mounting bracket 43 includes a left mounting vertical plate 9 and a right mounting vertical plate 10 arranged opposite each other. An upper mounting horizontal plate 11 and a lower mounting horizontal plate 44 are arranged opposite each other between the left mounting vertical plate 9 and the right mounting vertical plate 10.

A third pulley is located at the upper end of the third upper mounting shaft. The second pneumatic motor 19 is connected to the third pulley and the fourth pulley via a second transmission belt 46, causing the two booster wheels of the right booster assembly to rotate synchronously and in the same direction. Furthermore, the booster wheels of the left booster assembly 41 and the right booster assembly 42 rotate in opposite directions to facilitate the boosting operation. Figure 2 As shown, both the first transmission belt 45 and the second transmission belt 46 are synchronous belts. The first transmission belt 45 simultaneously drives the rotation of the first pulley and the second pulley, while the second transmission belt 46 simultaneously drives the third pulley and the fourth pulley. The air intake pipe of the first pneumatic motor 18 is connected to the air intake pipe 20 of the first cylinder; the air intake pipe of the second pneumatic motor 19 is connected to the air intake pipe 21 of the second cylinder.

[0033] Both the upper drilling wheel 3 and the lower drilling wheel 4 are cylindrical bodies arranged horizontally from left to right. The upper drilling wheel 3 has a first left mounting shaft 24 and a first right mounting shaft 25 at its left and right ends, respectively. The upper mounting plate 11 has an upper elongated mounting hole 22. The lower drilling wheel 4 has a second left mounting shaft and a second right mounting shaft at its left and right ends, respectively. The lower mounting plate 44 has a lower elongated mounting hole corresponding to the upper elongated mounting hole 22. Both the upper elongated mounting hole 22 and the lower elongated mounting hole have bearing mounting grooves 23 at their left and right ends. The upper drilling wheel 3 is mounted in the upper elongated mounting hole 22 through bearings mounted on the first left mounting shaft 24 and the first right mounting shaft 25.

Both the left punching wheel 5 and the right punching wheel 6 are vertically arranged cylinders. The left punching wheel 5 has a first upper connecting shaft 26 and a first lower connecting shaft 27 at its upper and lower ends, respectively. The first upper connecting shaft 26 is mounted on the upper mounting plate 11 through a third upper buffer assembly, and the first lower connecting shaft 27 is mounted on the lower mounting plate 44 through a third lower buffer assembly. The right punching wheel 6 has a second upper connecting shaft and a second lower connecting shaft at its upper and lower ends, respectively. The second upper connecting shaft is mounted on the upper mounting plate 11 through a fourth upper buffer assembly, and the second lower connecting shaft is mounted on the lower mounting plate 44 through a fourth lower buffer assembly.

[0034] The first upper buffer assembly, the first lower buffer assembly, the third upper buffer assembly, and the third lower buffer assembly have the same structure, all including a first rectangular hole 28. A first rectangular groove 29 is provided at the left end of the first rectangular hole 28. A first rectangular pad is installed in the first rectangular groove 29. A first horizontal slide rail is provided in the first rectangular hole 28. A first rectangular slider 30 is installed on the first slide rail.

The first upper mounting shaft, the first lower mounting shaft, the second upper mounting shaft, the second lower mounting shaft, the first upper connecting shaft 26, and the first lower connecting shaft 27 are all installed in the corresponding first bearing mounting holes 31 through corresponding bearings. A first buffer spring 32 is provided between the first rectangular slider 30 and the first rectangular pad.

A second buffer spring is provided between the second rectangular slider and the second rectangular pad.

[0035] During the boosting operation, although gas extraction pipes of different diameters will be boosted, the first buffer spring 32 and the second buffer spring of this application enable this application to adapt to gas extraction pipes of different diameters. When the gas extraction pipe is larger than the gap between the left boosting component 41 and the right boosting component 42, the first buffer spring 32 and the second buffer spring are compressed. The left boosting component 41 and the right boosting component 42 clamp the gas extraction pipe under the rebound force of the first buffer spring 32 and the second buffer spring, and boost the gas extraction pipe under the rotation of the boosting wheel.

[0036] The support frame 1 includes a rectangular horizontal support plate 33. The lower surface of the horizontal support plate has four corners connected by a multi-phase rotating assembly 34, which provides multi-stage telescopic support legs 35. The multi-phase rotating assembly 34 includes a perforated cylindrical solid, a perforated cylindrical shell, an upper ear plate, a first lower ear plate, and a second lower ear plate. The upper end of the perforated cylindrical solid is located on the lower surface of the horizontal support plate. The perforated cylindrical solid has several first circular holes around its circumference. The perforated cylindrical shell has second circular holes corresponding to the first circular holes. The perforated cylindrical shell is open at the top and closed at the bottom, and is fitted onto the outside of the perforated cylindrical solid by corresponding pins. The upper ear plate is located on the lower surface of the driving cylindrical shell. The first and second lower ear plates are both located at the top of the multi-stage telescopic support legs 35. The multi-stage telescopic support legs 35 and the rectangular horizontal support plate 33 are connected by corresponding pins that pass sequentially through the ear plate holes of the first lower ear plate, the upper ear plate, and the second lower ear plate. The height of the entire device can be adjusted by adjusting the length of the multi-stage telescopic support legs 35, thus ensuring that the booster mechanism 2 is directly opposite the gas extraction hole during operation.

[0037] The booster mechanism 2 is covered with a protective cover 36. The rear end face of the protective cover 36 has an inlet hole 37, a first pipe hole 38 corresponding to the first cylinder inlet pipe 20, and a second pipe hole 39 corresponding to the second cylinder inlet pipe 21. The inlet hole 37 is located directly behind the booster mechanism 2. The front end face of the protective cover 36 has an outlet hole 40, which is located directly in front of the booster mechanism 2. During operation, the gas extraction pipe enters between the left booster component 41 and the right booster component 42 through the inlet hole 37 and leaves the protective cover 36 through the outlet hole 40 to enter the gas extraction hole.

[0038] In operation, this application first uses suitable transportation equipment to smoothly transport the device to the pre-set location of the reserved gas extraction pipe inlet. Upon arrival at the site, a preliminary inspection of the surrounding environment is conducted. Then, based on the actual terrain and the height of the reserved gas extraction pipe inlet, the overall height of the device is slowly adjusted by adjusting the multi-stage telescopic support legs 35, aligning the outlet pipe 40 with the reserved gas extraction pipe inlet. Next, the power sources for the first pneumatic motor 18 and the second pneumatic motor 19 are connected and started. Close monitoring of various parameters during startup is maintained to ensure normal operation. After starting the first and second pneumatic motors 18 and 19, the device is preheated for 2-3 minutes. During the preheating process, continuously observe the operating status of each component of the device, and check for any abnormal vibrations, noises, or other signs of instability. If any are found, address them promptly. If none are found, wait until the device is running stably, then check for any foreign objects or damage behind the device. If any are found, address them promptly. If none are found, proceed with the boosting operation of the gas extraction pipe. Specifically, insert one end of the gas extraction pipe into the protective cover 36 through the inlet 37. The gas extraction pipe enters from the rear end of the boosting mechanism 2 between the first left booster wheel 14 and the first right booster wheel 16, and is continuously conveyed forward under the rotation of the first left booster wheel 14 and the first right booster wheel 16. When passing the upper perforating wheel 3 and the lower perforating wheel 4, the first perforation on the upper perforating wheel 3 and the lower perforating wheel 4... The drill bit 7 punches holes in the gas extraction pipe. As it passes the left and right punching wheels 5 and 6, the second drill bit 8 on these wheels punches holes in the pipe. The gas extraction pipe continues to move forward between the second left booster wheel 15 and the second right booster wheel 17. Under the combined action of the first left booster wheel 14, the first right booster wheel 16, the second left booster wheel 15, and the second right booster wheel 17, it continues to move forward. The gas extraction pipe exits through the outlet hole 40, leaves the protective cover 36, enters the gas extraction hole, and continues to move forward. Then, based on the needs of on-site gas extraction, the length of the screen hole section on the gas extraction pipe is calculated. When the required length of the screen hole section on the gas extraction pipe is observed, the boosting is stopped and all pneumatic motors are turned off. Remove the protective cover 36 to expose the booster mechanism 2. Remove the first punch 7 from the upper punching wheel 3 and the lower punching wheel 4, and remove the second punch 8 from the left punching wheel 5 and the right punching wheel 6. After removing all the punches, check each component of the device for damage or abnormalities. If any are found, repair or replace them promptly. If none are found, install the protective cover 36, restart all pneumatic motors, and continue the booster operation of the gas extraction pipe until the gas extraction pipe is completely inside the gas extraction hole. Finally, after the gas extraction pipe is completely inside the gas extraction hole, confirm that the gas extraction pipe is in place and there are no abnormalities. After confirmation, shut down the entire device, disconnect the power source, and clean and maintain the device in a timely manner to prepare for the next operation.

[0039] This application detachably installs several first perforating spikes 7 along the outer circumference of the upper perforating wheel 3 and the lower perforating wheel 4, and several second perforating spikes 8 along the outer circumference of the left opening wheel and the right opening wheel. The gas extraction pipe is perforated by the first perforating spikes 7 and the second perforating spikes 8. After the gas extraction pipe reaches the required screen hole section length, the first perforating spikes 7 and the second perforating spikes 8 are removed and the gas extraction pipe is transported again, thereby realizing the control of the screen hole section length of the gas extraction pipe and improving the applicability of the device.
