Description
Technical Field
The invention belongs to the technical field of underground or ground drilling equipment, and particularly relates to a multipurpose propelling device for a mining drill rod built-in flexible steel pipe.
Background
The traditional measures such as hydraulic slotting, hydraulic cave making and the like are simple to operate and have certain application effect, but the influence range is limited due to the short distance of jet flow for cutting the coal body; and when the jet flow is submerged by water, the resistance is increased, the kinetic energy is attenuated by orders of magnitude, and even the ultrahigh pressure jet flow of 100MPa is not obviously improved.
The research and field tests of mechanical reaming (hole making) techniques have also begun in a very early stage. The technology is mainly used for outburst prevention measures when the coal seam is uncovered. Generally, a mechanical retractable drill bit is used to draw out a part of the coal body to release the pressure of the coal body. Compared with hydraulic punching and hydraulic scouring, the large-diameter reaming and coal unloading measures have the obvious advantages that special equipment is not needed, and the large-diameter reaming and coal unloading measures can be realized only by using a common drilling machine and a large-diameter reaming drilling tool. But the mechanical performance of the reaming equipment needs to be improved, the service life of the drill bit is short, and the reliability is not high; the diameter of the drilled hole is too large, which is easy to induce protrusion.
At present, the drilling peeping technology can only be used for shallow holes with the depth of less than 50 meters generally, and deep holes with the depth of more than one hundred meters cannot be realized. And the drill rod is required to be withdrawn and then the operation is carried out, and the peeping of the drill hole can not be carried out without withdrawing the drill rod in the drilling process.
In the current underground drilling process, no efficient solution is available for eliminating blockage and cleaning of the inner wall of a drill rod.
If soft coal (rock) is encountered in the process of drilling underground drill holes, mechanical drilling (hydraulic drilling can be adopted) cannot be continued sometimes, drilling is stopped or the drill rod is completely withdrawn to replace the drill bit to continue drilling, and time and labor are wasted.
Aiming at the actual conditions, according to coal seam occurrence conditions, roadway arrangement and mining processes, the technology similar to an oil pipe technology in oil field development is developed, hydraulic drilling by using a branch pipe made of a high-deflection low-carbon special steel material is particularly important, and in engineering practice, a device for pushing or withdrawing the branch pipe is designed as a key link for solving the problems.
The drill rod is made of a hollow steel pipe, and two ends of the drill rod are provided with threads for connection. The drill rod is a transmission part which transmits power from the drilling machine to the drill bit when the drilling machine drills underground or on the ground, not only transmits thrust, but also transmits torque, and transmits high-pressure water flow for cooling the drill bit and discharging drill cuttings. When the hydraulic coal body cutting construction or other purposes are carried out, sometimes a flexible steel pipe is arranged in a drill rod and is used for cutting a horizontal branch hole, conveying high-pressure water and other purposes. Because the distance for conveying the flexible steel pipe is long and the resistance is large, the flexible steel pipe needs to turn and convey high-pressure water flow under specific conditions, and the propelling and withdrawing of the flexible steel pipe in the drill rod need to be completed by a special mechanical device.

In the referenced drawings, the same or similar components in different drawings are denoted by the same reference numerals.
The first embodiment is as follows:
as shown in fig. 1 to 4, in the propulsion device of the multi-purpose mining drill rod built-in flexible steel pipe of the present invention, the tail of the drill rod 1 is sequentially connected with the connecting device 3, the end square pipe 42, the middle square pipe 4, the end flange 43 and the front clamp 5, and the gland 41 is used for fixing the connecting device 3 and the end square pipe 42 and enabling the connecting device 3 and the end square pipe 42 to relatively rotate. The front clamper 5 and the rear clamper 7 are both arranged on a guide rail 9, wherein the front clamper 5 is fixed, and the rear clamper 7 can move on the guide rail driven by a driving mechanism. The flexible steel pipe 6 sequentially passes through the rear clamp holder 7, the front clamp holder 5, the end flange 43, the middle square pipe 4, the end square pipe 42, the connecting device 3, the gland 41 and the drill rod 1.
The rear clamper 7 is moved back and forth along the guide rail by a hydraulic cylinder 8 of the driving mechanism. The guide rail 9 is supported by a support column 15, the support column 15 serving to fix the guide rail 9. The console 12 is used for operating the front clamper 5, the rear clamper 7 and the hydraulic cylinder 8. The pump station 13 provides hydraulic power for the hydraulic cylinder 8. The console 12 controls the operation of the entire apparatus. The pump station 13 is connected with the hydraulic oil cylinder 8 through an oil pipe 45, so that the automation of the working link is realized, and the drilling work efficiency is greatly improved.
The end square pipes 42, the middle square pipes 4 and the end flanges 43 are hinged, wherein the number of the end square pipes 42 and the number of the end flanges 43 are respectively 1, the number of the middle square pipes 4 is 5-30 according to the specific conditions (such as the length of a flexible steel pipe), and the middle square pipes 4 can rotate by an angle, and the flexible steel pipes 6 can be bent, so that any included angle can be formed between the guide rails 9 and the drilling machine 2, and the flexible steel pipes are convenient to place. The middle square tube 4 has a certain limiting effect on the flexible steel tube 6, so that the flexible steel tube is prevented from being broken or having overlarge curvature, and the resistance of the flexible steel tube 6 in propelling can be reduced.
When in use, the number of the flexible steel pipes 6 can be 1, and the length can be selected within the range of 6-200 meters; or 2-30 flexible steel pipes 6 are connected through joints 44.
The flexible steel pipe 6 is pushed in the following process:
firstly, when the operation is started, the connection of the related parts is finished.
And secondly, loosening the front clamp holder 5, and contracting the rear clamp holder 7 to enable the rear clamp holder 7 to clamp the flexible steel pipe 6.
And thirdly, under the pushing of the hydraulic cylinder 8, the rear clamp 7 moves forwards on the guide rail, and meanwhile, the flexible steel pipe 6 is pushed to move forwards in the drill rod. Until the rear clamper 7 cannot move.
Fourthly, the front clamp holder 5 is tightened, and the flexible steel pipe 6 is still. The rear clamper 7 is released, and the rear clamper 7 moves backward under the action of the hydraulic cylinder 8 and returns to the initial position.
And fifthly, repeating the steps from two to four to continuously push the flexible steel pipe 6 into the drill rod 1. The steps for withdrawing the flexible steel tube 6 from the drill rod 1 are similar.
The rear gripper 7 can move back and forth on the guide rail 9 until the flexible steel tube 6 is conveyed to a preset position.
Example two
The second embodiment is the same as the first embodiment in structure and operation, and is different from the first embodiment in that the rear clamper 7 is pushed by the rack 17 and the power device 14. The power device 14 is connected with the rear holder 7, and a gear rotating in the power device 14 is engaged with the rack 17 to push the power device 14 and the rear holder 7 to move forward (the rack 17 is fixed).
EXAMPLE III
The third embodiment is the same as the first embodiment in structure and operation, and is different in that the rear clamper 7 is pushed by a power device 16 to drive a chain 11, the chain 11 rotates around two chain wheels 10 arranged on a guide rail 9, the chain 11 is fixedly connected with the rear clamper 7, and the rear clamper 7 moves forwards and backwards along with the chain 11.
The propelling device and the drilling machine can form any angle, and the distance between the propelling device and the drilling machine can be kept between 1 and 3 meters, so that the arrangement is flexible and is not limited by space.
The flexible steel pipe 6 has higher strength, certain flexibility (the bending radius can be less than 1.2 meters) and higher pressure resistance (can convey fluid with the pressure of 30 MPa), so that the flexible steel pipe can complete various works. The multipurpose propelling device for the mining drill rod with the built-in flexible steel pipe is mainly applied as follows:
application example 1:
as shown in fig. 5, the horizontal branch hole is punched by the propulsion device of the present invention, and the flexible steel pipe 6 is turned by the guider 101 so that the front end of the flexible steel pipe points to the horizontal direction. A nozzle 104 is installed at the front end of the flexible steel pipe 6, and a coal body is cut by high-pressure water jet to form a horizontal branch hole in a coal seam 105.
Application example 2:
as shown in fig. 6, the mechanical drilling instead of the jet punching drilling without withdrawing the drill rod is realized by the invention: the drilling machine 2 is placed at the outlet of the drill hole 102, and the drill rods 1 are passed through the middle of the drilling machine 2, and a plurality of them are connected to each other until reaching the bottom of the drill hole 102. The upper part of the endmost drill rod is connected to a drill bit 203. The drill 203 has a through hole in the middle. The outer side of the flexible steel pipe 6 is connected with a high-pressure water pipe, and the high-pressure water pipe penetrates through the outermost drill rod and reaches the drill hole 102 until penetrating through the hole of the drill bit 203. The tail end of the flexible steel pipe 6 is provided with a high-pressure nozzle.
When the drill bit 203 is mechanically drilling to a certain position, normal mechanical drilling operations cannot or need not continue under certain conditions, such as: 1) when a borehole having a diameter exceeding 120mm is forbidden in a protruding coal seam; 2) the small-diameter drill hole completely meets the requirements; 3) the large-diameter drill hole is easy to collapse; 4) the drill bit is worn seriously and cannot drill. In this case, the rotation and advance and retreat of the drill rod 1 are stopped, the high-pressure water pipe is connected to the outside of the flexible steel pipe 6, the high-pressure nozzle 104 is attached to the tip, and the flexible steel pipe 6 is passed through the outermost drill rod to reach the drill hole 102 until it passes through the water passage hole of the drill bit 203. At this time, the flexible steel pipe 6 can be pushed forward by the device, and the coal rock mass in front is cut by high-pressure water to form a small-diameter drill hole 210. The mechanical drilling instead of the jet flow punching drilling is realized without withdrawing the drill rod.
Application example 3:
as shown in fig. 7, the deep hole peeking is realized by the present invention: the front end of the flexible steel pipe 6 is provided with a camera 204, the cable 202 is connected with the main machine 201 of the drilling peeping instrument, and is always connected with the camera 204 through the interior of the flexible steel pipe 6. Images and videos of the borehole 102 can be captured and recorded by the camera 204. Due to the protection of the drill rod 1 and the flexible steel pipe 6, the camera 204 and the cable 202 can be prevented from being damaged; due to the high strength of the flexible steel pipe 6, the hole collapse position of the drilling hole 102 can be easily passed. In a word, the structure can send the camera 204 into the deep part (up to 200 meters) of a deep borehole, and realizes the borehole peeping of the deep hole so as to obtain geological data of a coal rock layer.
Application example 4:
as shown in fig. 8, the drill rod is cleaned and dredged by the present invention: under certain conditions, the water through holes in the drill rod and the drill bit are blocked by coal (rock) blocks 205, or mud, cement and other attachments 206 on the inner wall of the drill rod are stuck on the inner wall of the drill rod, so that the passing of the internal water flow is influenced, and even when drilling cannot be continued, the following scheme can be adopted for solving the problem:
the front end of the flexible steel pipe 6 is provided with a spray head 104, the rear end of the flexible steel pipe is connected with a high-pressure water pipe, and under the action of a propelling device, the flexible steel pipe 6 advances in the drill rod and simultaneously sprays high-pressure water to crush and flush out the blocked coal (rock) blocks 205; and simultaneously washing away the attachments 206 on the inner wall of the drill rod.
