Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Referring to fig. 1, the present embodiment provides a horizontal hole fisher throwing propulsion device, which specifically includes a hollow water pipe joint 5, a pressure regulating pipe 1, a hollow pressure collecting pipe 7, and a rope conveying pipe 3, which are sequentially arranged from top to bottom.
The rope conveying device comprises a rope conveying pipe 3, a pressure gathering pipe 7, a sealing element 2, a rope conveying pipe 3 and a first avoidance hole 6, wherein the sealing element 2 is arranged in the pressure gathering pipe 7, the bottom end of the sealing element 2, the bottom end of the pressure gathering pipe 7 and the top end of the rope conveying pipe 3 are on the same plane, and the top end of the rope conveying pipe 3 and the sealing element 2 are both provided with the first avoidance hole 6; the top at the pressure-concentrating pipe 7 is connected to pressure regulation pipe 1 is detachable, be provided with the second in the pressure regulation pipe and dodge hole 8, hole 8 and the first coaxial setting of dodging hole 6 are dodged to the second to make wire rope's one end pass the second in proper order and dodge hole 8, the first hole 6 of dodging, send rope pipe 3 and be connected with the fisher, because the second dodges hole 8 and the first coaxial setting of dodging hole 6, make wire rope can pass this horizontal hole fisher smoothly and throw in advancing device. Illustratively, the diameters of the first avoidance hole 6 and the second avoidance hole 8 in the horizontal hole fisher throwing propulsion device are 12 mm; during specific implementation, the diameters of the first avoidance hole 6 and the second avoidance hole 8 can be flexibly designed according to the diameter of the steel wire rope, and the diameters of the first avoidance hole and the second avoidance hole can be matched with the diameter of the steel wire rope and meet the requirement of normal passing of the steel wire rope.
Meanwhile, the bottom end of the rope conveying pipe 3 is oppositely connected with the top end of a drill rod arranged in a drill hole; and the one end setting of water pipe head 5 is on the lateral wall of rope pipe 3 to make outside water pass through water pipe head 5 in proper order, send rope pipe 3 to get into in the drilling rod, in order to promote wire rope and fisher to move to the drilling bottom, wherein, the one end of water pipe head 5 for example can weld on the lateral wall of rope pipe 3. The pressure adjusting pipe 1 can move up and down along the pressure gathering pipe 7, so that the outer wall of the sealing element 2 is in sealing fit with the inner wall of the pressure gathering pipe 7, and the rope clamping position of the steel wire rope passes through the pressure gathering pipe 7.
During specific implementation, the sealing element 2 is firstly placed inside the pressure gathering pipe 7, and then one end of the steel wire rope sequentially passes through the second avoiding hole 8, the first avoiding hole 6 and the rope conveying pipe 3 and penetrates out of the bottom end of the rope conveying pipe 3 to be connected with the fisher. One end of the steel wire rope can be tied with the fisher to realize the connection and fixation of the steel wire rope and the fisher; in some embodiments, a rope clip may be disposed at one end of the steel wire rope, and a buckle that is connected to the rope clip in a matching manner is disposed on the fisher, so as to fix the connection between the steel wire rope and the fisher. Treat that wire rope's one end and fisher are connected fixedly back, put into the drilling rod of horizontal drilling with the fisher again, then will send rope pipe 3 to be connected with the drilling rod relative of horizontal hole, link together pressure regulating pipe 1 and pressure collecting pipe 7 detachablely at last, it links to each other to screw up the high-pressure pipe of water pump and water pipe head 5 simultaneously, and inspect the fastness of its connection, open the water pump this moment, increase the pump pressure gradually, in order to promote under water pressure and make fisher and wire rope move to the hole bottom, can accomplish the input of horizontal hole fisher and impel. After the fisher reaches the bottom of the horizontal drilling hole, the fisher can be buckled with an inner pipe assembly arranged at the upper part of an inner pipe filled with samples such as rock samples or soil samples, and the samples can be taken out by pulling up the steel wire rope and the fisher so as to carry out geological exploration analysis research.
When the fisher is thrown in the ultra-deep horizontal hole, the loss and splicing of the steel wire rope are increased, so that the problem of rope clamping is easy to occur when the steel wire rope is thrown and pushed. At first, the pressure regulating pipe 1 is normally connected with the pressure accumulating pipe 7, wherein the sealing element 2 inside the pressure accumulating pipe 7 can enable the inside of the pressure accumulating pipe 7 to be in an initial sealing state, and at the moment, pressure is formed in the pressure accumulating pipe 7 and can push the steel wire rope to normally move. And can block in pressure pipe 7 when pressure pipe 7 is pressed through gathering to the concatenation department when wire rope, only need adjust pressure regulating pipe 1 this moment make it follow pressure pipe 7 downstream in order to press sealed sealing member 2 to make sealed member 2's outer wall and gather and press sealed laminating between the inner wall of pipe 7, thereby increased the pressure of pressure pipe 7 inside, the pressure that increases in the twinkling of an eye makes wire rope's card rope department smoothly pass through pressure pipe 7 that gathers. And after the rope is clamped, the pressure adjusting pipe 1 moves upwards along the pressure gathering pipe 7, even if the position of the pressure adjusting pipe 1 is restored to the original state, the process is repeated, and when the rope is clamped, the steel wire rope can pass through smoothly according to the steps, so that the throwing and propelling task of the horizontal deep hole fisher is realized.
That is to say, this advancing device is thrown in to horizontal hole fisher when the card rope problem of wire rope concatenation department appears, need not to dismantle whole device, only need through make pressure regulating pipe 1 move down in order to adjust the smooth passing through that the inside pressure of pressure collecting pipe 7 can realize wire rope concatenation department to greatly saved the manpower, reduced the input time of fisher, also improved the normal operating efficiency of fisher simultaneously, and protected the structure of the water pump of being connected with water pipe head 5. For example, when the horizontal hole fisher throwing propulsion device is applied to an ultra-deep horizontal hole with the depth of 1000m, the throwing time of the fisher can be reduced to about 40 minutes from 210 and 250 minutes in the prior art.
After the putting-in and fishing work of the fisher is completed, the fisher in the horizontal hole is only required to be put in the pushing device to be loosened from the drill rod, then the steel wire rope is pulled upwards to drive the fisher and the inner pipe filled with the sample to move upwards, the fisher and the inner pipe are moved out of the drilled hole, and finally the fisher in the horizontal hole is pushed to be placed beside the drilling machine without being detached for next use.
