Description

Technical Field

[0001] This utility model relates to the field of drilling rig drill rod technology, and in particular to a drilling rig drill rod clamping and support structure for trenchless construction. Background Technology

[0002] Drill pipe is a key component connecting the drilling rig and drill bit in drilling operations. It is primarily used to transmit power, transport drilling fluid, and withstand complex working conditions. The following are detailed classifications and characteristics: Basic Functions: Drill pipe forms the drill string through threaded connections, transmitting power from the drilling rig to the drill bit, transporting drilling fluid to cool the drill bit, carrying cuttings, and withstanding extreme conditions such as high pressure, torque, and vibration. Main Classifications: Square drill pipe is located at the top of the drill string and is divided into square and hexagonal types. It is made of high-strength alloy steel and has a wall thickness three times greater than that of ordinary drill pipe.

[0003] An existing drilling rig rod clamping and support structure for trenchless construction has a problem: when workers cooperate with support equipment to support the drilling rig rods for trenchless construction, the clamping and limiting positions of the support equipment are fixed because the lengths of the drilling rig rods vary. This makes it inconvenient for the support equipment to limit and clamp the drilling rig rods according to their actual length, thus affecting the stability of the support equipment when clamping the drilling rig rods. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a drill rod clamping and support structure for trenchless construction.

[0005] This utility model is achieved by the following technical solution: a drilling rod clamping and support structure for trenchless construction, including a drilling rod, a fixing ring slidably connected to the surface of the drilling rod, a locking screw threadedly connected to the inside of the fixing ring, and a rotating column fixedly connected inside the fixing ring.

[0006] A connecting crossbar is hinged to the surface of the first rotating column. A rotating column is fixedly connected inside the connecting crossbar. An adjusting cross plate is hinged to the surface of the rotating column. An adjusting screw is slidably connected inside the adjusting cross plate. A locking nut is threadedly connected to the surface of the adjusting screw. A second rotating column is hinged to the surface of the second rotating column. A second fixing ring is fixedly connected to the surface of the second fixing ring. A connecting screw is threadedly connected to the surface of the second fixing ring. A supporting vertical plate is hinged to the surface of the adjusting screw. A limit base is hinged to the interior of the supporting vertical plate.

[0007] Through the above technical solution, the pre-embedded rotating column extends outward to two hinged fulcrums symmetrically distributed on the left and right with the center line as the axis, which are respectively connected to the connecting crossbars on both sides. These two crossbars, like mechanical arms, transmit power to the execution unit below, forming the first-level motion conversion system.

[0008] As a further improvement to the above solution, the second fixing ring is slidably connected to the surface of the drill rod of the drilling rig, the second fixing ring is located at the bottom of the first fixing ring, and the second fixing ring is located at the bottom of the locking screw.

[0009] As a further improvement to the above scheme, the number of the rotating column and the connecting crossbar is set to two, and the two rotating columns and the connecting crossbar are symmetrically distributed on the left and right sides with the fixed ring as the center.

[0010] With the above technical solution, the fixing ring 1 serves as the initial installation reference component, with its inner wall slidingly fitted onto the surface of the drill rod of the drilling rig, and the axial position is locked by a radially inserted locking screw.

[0011] As a further improvement to the above solution, the surface of the locking nut is in contact with the surface of the supporting vertical plate, and the number of the locking nuts is set to several, which are symmetrically distributed back and forth around the adjusting horizontal plate.

[0012] Through the above technical solution, the built-in groove of this horizontal plate allows the adjusting screw to pass through it longitudinally. The locking nuts at both ends can generate deformation stress by squeezing the horizontal plate through the tightening operation, thereby precisely controlling the extension range of the entire lever system. The two sets of adjusting screws are arranged in a left-right mirror image directly below the drill rod to ensure balanced force and no off-center load phenomenon.

[0013] As a further improvement to the above scheme, the number of the adjusting screws is set to two, and the two adjusting screws are symmetrically distributed on the left and right sides with the drill rod of the drilling rig as the center, and the adjusting screws are located at the bottom of the connecting crossbar.

[0014] As a further improvement to the above solution, the number of the supporting vertical plate and the limiting base is set to two, and the two supporting vertical plates and the limiting base are symmetrically distributed on the left and right sides with the drill rod of the drilling rig as the center.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] After the fixed rings 1 and 2 are installed on the drill rod of the drilling rig, the fixed distance between the fixed rings 1 and 2 can be adjusted by using the internally hinged connecting crossbar and adjusting crossbar. After disassembling from the surface of the adjusting screw and the supporting vertical plate by rotating the locking nut, the supporting vertical plate can be pulled to slide inside the adjusting crossbar in conjunction with the adjusting screw. This allows for adjustment of the support angle between the supporting vertical plate and the limiting base, increasing the overall flexibility of the equipment and the support stability during fixing.

[0017] This utility model sets up a hinged rotating column at the end of the adjusting horizontal plate, which drives the fixed ring at the moving end to swing synchronously. The ring also adopts a split structure and slides on the outer circle of the drill rod, and is located in the vertical projection area of ​​the upper fixed ring. The two together form a double clamp-type constraint system. The rigid connection between the two rings is further strengthened by setting a connecting screw added at the bottom, which effectively suppresses the risk of loosening caused by high frequency vibration.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4 This embodiment of a drilling rig rod clamping and support structure for trenchless construction includes a drilling rig rod 1, a fixing ring 2 slidably connected to the surface of the drilling rig rod 1, a locking screw 3 threadedly connected to the inside of the fixing ring 2, and a rotating column 4 fixedly connected to the inside of the fixing ring 2.

[0027] A connecting crossbar 5 is hinged to the surface of the rotating column 4. A rotating column 6 is fixedly connected inside the connecting crossbar 5. An adjusting crossbar 7 is hinged to the surface of the rotating column 6. An adjusting screw 8 is slidably connected inside the adjusting crossbar 7. A locking nut 9 is threadedly connected to the surface of the adjusting screw 8. A rotating column 10 is hinged to the surface of the adjusting crossbar 7. A fixing ring 11 is fixedly connected to the surface of the rotating column 10. A connecting screw 12 is threadedly connected to the surface of the fixing ring 11. A supporting vertical plate 13 is hinged to the surface of the adjusting screw 8. A limiting base 14 is hinged to the interior of the supporting vertical plate 13.

[0028] The pre-embedded rotating column 4 extends outward to two hinged fulcrums symmetrically distributed on the left and right with the center line as the axis, which are respectively connected to the connecting crossbars 5 on both sides. These two crossbars, like mechanical arms, transmit power to the execution unit below, forming the first-level motion conversion system.

[0029] Fixed ring 2 11 is slidably connected to the surface of drill rod 1 of the drilling rig. Fixed ring 2 11 is located at the bottom of fixed ring 1 2 and at the bottom of locking screw 3. After fixed ring 1 2 and fixed ring 2 11 are installed on drill rod 1 of the drilling rig, the fixed distance between fixed ring 1 2 and fixed ring 2 11 can be adjusted by using the internally hinged connecting crossbar 5 and adjusting crossbar 7. After the locking nut 9 is removed from the surface of adjusting screw 8 and support vertical plate 13 by rotating it, the support vertical plate 13 can be pulled to slide inside adjusting crossbar 7 in conjunction with adjusting screw 8. This can adjust the support angle between support vertical plate 13 and limit base 14, increasing the overall flexibility of the equipment and the support stability during fixing.

[0030] The number of rotating column 4 and connecting crossbar 5 is set to two, and the two rotating column 4 and connecting crossbar 5 are symmetrically distributed on the left and right with the fixed ring 2 as the center.

[0031] The fixing ring 2 serves as the initial installation reference component, with its inner wall slidingly fitted onto the surface of the drill rod 1 of the drilling rig, and its axial position is locked by the radially inserted locking screw 3.

[0032] The surface of the locking nut 9 is in contact with the surface of the supporting vertical plate 13. The number of locking nuts 9 is set to several, and the several locking nuts 9 are symmetrically distributed back and forth with the adjusting horizontal plate 7 as the center.

[0033] The built-in groove of this horizontal plate allows the adjusting screw 8 to pass through it longitudinally. The locking nuts 9 at both ends can generate deformation stress by tightening the horizontal plate, thereby precisely controlling the extension range of the entire lever system. The two sets of adjusting screws 8 are arranged in a left-right mirror image directly below the drill rod to ensure balanced force and no off-center load.

[0034] Two adjusting screws 8 are set, and the two adjusting screws 8 are symmetrically distributed on the left and right sides with the drill rod 1 of the drilling rig as the center. The adjusting screws 8 are located at the bottom of the connecting crossbar 5. The rotating column 10 is hinged to the end of the adjusting crossbar 7, which drives the fixed ring 11 at the moving end to swing synchronously. The ring body also adopts a split structure and slides on the outer circle of the drill rod, and is located in the vertical projection area of ​​the upper fixed ring 2. The two together form a double clamp-type constraint system. The rigid connection between the two rings is further strengthened by setting the connecting screw 12 added at the bottom, which effectively suppresses the risk of loosening caused by high frequency vibration.

[0035] The number of supporting vertical plates 13 and limiting bases 14 is set to two, and the two supporting vertical plates 13 and limiting bases 14 are symmetrically distributed on the left and right with the drill rod 1 of the drilling rig as the center.

[0036] The implementation principle of the drilling rod clamping support structure for trenchless construction in this application embodiment is as follows: After the fixing ring 11 and fixing ring 22 are installed on the drilling rod 1, the fixed distance between fixing ring 11 and fixing ring 21 can be adjusted by the internally hinged connecting crossbar 5 and adjusting crossbar 7. After the locking nut 9 is removed from the surface of the adjusting screw 8 and the supporting vertical plate 13 by rotating it, the supporting vertical plate 13 can be pulled to slide inside the adjusting crossbar 7 in conjunction with the adjusting screw 8. This can adjust the support angle between the supporting vertical plate 13 and the limiting base 14, increasing the overall flexibility of the equipment and the support stability during fixing. By setting the adjusting crossbar 7 to be hinged to the rotating column 210, the fixed ring 21 at the moving end is driven to swing synchronously. The ring body also adopts a split structure and slides on the outer circle surface of the drilling rod, and is located in the vertical projection area of ​​the upper fixing ring 12. The two together form a double clamp constraint system. By setting the connecting screw 12 added at the bottom, the rigid connection between the two rings is further strengthened, effectively suppressing the risk of loosening caused by high frequency vibration.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
