Description

Technical Field

[0001] The invention relates to the technical field of supporting bases, and in particular to a supporting base for a drilling rig and a drilling platform. Background Art

[0002] The base of the drilling equipment is usually located at the bottom of the drilling rig. It is a key structure that supports the weight of the entire drilling rig. It is usually welded from steel and has sufficient strength and rigidity to ensure the stability and safety of the drilling rig. The base not only supports and fixes various parts of the drilling rig and provides a working place, but also facilitates the relocation and transportation of the drilling rig, installs and fixes wellhead equipment, and protects the drilling rig and the ground.

[0003] In the prior art, in order to meet the relocation and transportation needs of the drilling rig, the base usually adopts a modular design that can be easily disassembled and assembled. However, the base composed of multiple components and assemblies often has a complex structure and many parts. This complexity not only increases the manufacturing cost, but also may lead to difficulties in maintenance and repair. The use of multiple assembly parts may also affect the stability and reliability of the base, bringing potential risks to the drilling operation. In addition, during the relocation and transportation of the base, the control equipment installed on the top also needs to be disassembled and transported separately, which not only increases the risk of accidental collision, but also increases the transportation cost and time, which is not conducive to the rapid movement of the base.

[0004] In addition, when fixing the base of the equipment, transport frames are currently installed on both sides for auxiliary support. However, the transport frames are mostly used to disperse the gravity applied downward by the derrick, and their gripping ability is relatively weak. However, during the construction process, the entire device is prone to up and down vibrations, causing partial displacement of the base, making it difficult to remove the drill bit driven into the ground, which is not conducive to the smooth progress of the drilling process.

[0005] In view of this, the present invention proposes a drilling rig rig support base to compensate for and improve the deficiencies of the prior art. Summary of the invention

[0016] Preferably, the blocking piece is located below the rotating ring block, and a protrusion is provided on the top of the rotating block.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During mobile transportation, the drilling platform body and the support frame can be transported together through the setting of the self-balancing mechanism, avoiding the use of multiple parts for disassembly and assembly, so as to reduce transportation costs and time. Under complex terrain conditions, the crawler and the protective shell seat can be flipped up and down along the slope of the ground and move forward, but the arc-shaped chassis slides on the top of the protective shell seat, so that the drilling platform body and the control equipment installed on its top can always maintain a stable state, reducing the risk of accidental collision of the control equipment. At the same time, the sliding range of the arc-shaped chassis is controllable under the stretching and limiting action of the telescopic rod at the bottom of the drilling platform body, and the roller is set to roll in the rolling groove, which can reduce the friction between the arc-shaped chassis and the protective shell seat, so that within a certain slope range, the protective shell seat and the crawler move along the slope of the ground, and the arc-shaped chassis drives the top support frame and the drilling platform body to automatically maintain the initial position without tilting, thereby increasing the stability between the equipment on the top of the drilling platform body, improving the safety of drilling operations, and facilitating the rapid relocation and transportation of the base, thereby increasing operating efficiency.

[0018] Secondly, by opening the folding rod horizontally, the two sides of the protective shell seat are fixed to make the force even, to prevent the large difference in terrain on both sides from causing the support frame to deform due to the lateral shear force, further enhancing the operating ability of the drilling platform in extreme environments, expanding the scope of application, and reducing equipment damage and maintenance costs caused by environmental factors. In addition, while the folding rod is horizontally unfolded, the arc guide plate is moved downward and close to the ground. The arc on the surface of the arc guide plate can be used as protection and guidance. During the movement, the gravel and soil in front of the crawler track are pushed away first, eliminating unnecessary resistance and obstacles to the advance, and assisting the crawler track to run smoothly.

[0019] 2. Through the mutual cooperation of the telescopic rod, the elastic slider and the casing, the end design of the elastic slider can significantly reduce the collision between the arc-shaped base and the protective shell seat. This buffering effect is particularly important when the drilling platform is started and stopped. It can effectively reduce the impact force caused by sudden acceleration or deceleration, and effectively prevent the equipment parts on the drilling platform body from shifting or being damaged, thereby protecting the integrity and functionality of the equipment. In conjunction with the locking function of the card block, it can also assist in leveling the drilling platform body, which helps to improve the working efficiency and operation accuracy of the drilling platform, and ensure the accuracy and safety of operations such as drilling.

[0020] 3. During drilling construction, the side support stabilization mechanism is set up and double-headed piles are used to connect the outer edge of the protective shell seat to the ground to prevent the device from tipping over or supporting shaking. The inclined setting of the double-headed piles can effectively reduce the resistance when driving into the ground. At the same time, after the double-headed piles are tilted and nailed into the ground, the vertical force during construction is difficult to move the double-headed piles, which improves the grip of the base and avoids the phenomenon of partial displacement of the base due to up and down vibrations, making it difficult to remove the drill bit. At the same time, the setting of the two pile heads of the double-headed piles increases the piling area and improves the overall stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The blocking piece 46 is located below the rotating ring block 44 , and a protrusion is provided on the top of the rotating block 49 .

[0041] The protrusion on the top of the rotating block 49 is used to prevent the rotating ring block 44 from derailing and cooperates with the blocking piece 46 to limit the position.

[0042] The effects achieved by this embodiment are as follows: In the prior art, the base composed of multiple components and assemblies is often complex in structure and has many parts. This complexity not only increases the manufacturing cost, but also may lead to difficulties in maintenance and repair. The use of multiple assembled parts may also affect the stability and reliability of the base, bringing potential risks to drilling operations. Compared with the prior art, through the implementation of this embodiment, the self-balancing mechanism 4 is set to be able to move synchronously along the slope of the ground when the terrain is uneven, but the arc-shaped base frame 45 moves one step slower under the action of inertia, and because the bottom of the arc-shaped base frame 45 is set as an arc surface, the roller 411 rolls in the rolling groove 412, which reduces the friction between the arc-shaped base frame 45 and the protective shell seat 41, so that within a certain slope range, the protective shell seat 41 and the crawler 3 move along the slope of the ground, and the arc-shaped base frame 45 drives the top support frame 2 and the drilling platform body 1 to automatically maintain the initial position without tilting.

[0043] For further examples, please refer to Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the side support stabilizing mechanism 5 includes a pair of double-headed cylinders 51 fixedly connected to the middle part of the protective shell seat 41, the outer walls of the pair of double-headed cylinders 51 are fixedly connected to the side of the protective shell seat 41 away from each other, the tops of the double-headed cylinders 51 are fixedly connected to a pair of branch pipes 52, the output ends of the four branch pipes 52 are fixedly connected to the first inclined blocks 53, and the outer walls of the four first inclined blocks 53 are slidably connected to the outer wall of the protective shell seat 41.

[0044] The side support stabilization mechanism 5 also includes four slide rods 54 slidably connected to the inner wall of the first inclined block 53. A pair of limiting grooves 58 are opened on both sides of the protective shell seat 41 near the slide rods 54. The outer walls of the four slide rods 54 are slidably connected to the limiting grooves 58. The side of the slide rod 54 away from the first inclined block 53 is slidably connected to the second inclined block 55. The outer walls of the four second inclined blocks 55 are fixedly connected to the outer wall of the protective shell seat 41. The bottom of the slide rod 54 is slidably connected to a double-headed pile 56. The outer walls of the bottom of the four double-headed piles 56 are slidably connected to a pair of inclined sliding blocks 57. The outer walls of the four pairs of inclined sliding blocks 57 are fixedly connected to the outer wall of the protective shell seat 41.

[0045] The double-headed piles 56 are both inclined relative to the slide rod 54, and the second inclined block 55 and the first inclined block 53 are symmetrically arranged.

[0046] The inclination angle of the limiting groove 58 is consistent with that of the second inclined block 55 .

[0047] The inclination angle of the limiting groove 58 is consistent with that of the second inclined block 55 , so as to ensure that the slide rod 54 moves downward in parallel and moves toward the direction of the second inclined block 55 , thereby increasing the oblique squeezing force on the double-headed pile 56 .

[0048] The effects achieved by this embodiment are as follows: In the prior art, most transport frames are used to disperse the gravity of the derrick, and their gripping ability is relatively weak. During the drilling process, the base often vibrates, causing partial displacement of the base, making it difficult to remove the drill bit. Compared with the prior art, through the implementation of this embodiment, the side support stabilization mechanism 5 is set up, and the outer edge of the protective shell seat 41 can be connected to the ground with a double-headed pile 56 to prevent the device from tipping over or supporting shaking. In addition, the double-headed pile 56 is set at an angle, which reduces the resistance when it is driven into the ground, and the vertical force is difficult to move the double-headed pile 56, thereby improving the gripping ability.

[0049] The complete usage steps and working principle of the above embodiment are as follows: in the initial state: the arc-shaped base frame 45 is located in the middle of the protective shell seat 41, the rotating block 49 is clamped to the outer wall of the clamping block 47, and the double-headed pile 56 is retracted to the outer wall of the protective shell seat 41.

[0050] When in use, after the equipment completes drilling, first remove the derrick and other equipment, then the crawler 3 can be used to drive the drilling platform body 1 and the support frame 2 to move to the next location. Before moving, the staff can first rotate the rotating ring block 44 to move the rotating ring block 44 toward the direction of the casing 43, thereby releasing the abutment of the rotating ring block 44 on the rotating block 49. Therefore, the rotating block 49 can rotate at the top of the casing 43 and release the clamping of the rotating block 49 and the clamping block 47, so that the telescopic rod 48 can drive the elastic slider 410 to slide arbitrarily on the inner wall of the casing 43. When the crawler 3 is started, the crawler 3 can drive the protective shell seats 41 on both sides to move synchronously. If it encounters a ground In the case of uneven terrain, the crawler 3 and the protective shell seat 41 move synchronously along the slope of the ground, but the arc-shaped base frame 45 sliding on the top of the protective shell seat 41 moves slower under the action of inertia, and because the bottom of the arc-shaped base frame 45 is set as an arc surface, the roller 411 rolls in the rolling groove 412, which reduces the friction between the arc-shaped base frame 45 and the protective shell seat 41, so that within a certain slope range, the protective shell seat 41 and the crawler 3 move along the slope of the ground, and the arc-shaped base frame 45 drives the top support frame 2 and the drilling platform body 1 to automatically maintain the initial position without tilting, thereby increasing the firmness of the equipment on the top of the drilling platform body 1.

[0051] Furthermore, when the ground slope reaches the maximum value of the device, the telescopic rod 48 drives the elastic slider 410 to slide to the end of the sleeve 43, and the elastic force of the elastic slider 410 itself is used to buffer the drilling platform body 1, thereby reducing the collision between the arc-shaped base frame 45 and the protective shell seat 41. At the same time, when the slope is within the normal range, the telescopic rod 48 drives the elastic slider 410 to telescopically support in the sleeve 43, which also plays a buffering role, effectively preventing the equipment parts on the drilling platform body 1 from being displaced or damaged, thereby increasing the service life of the equipment. Before construction, the rotating ring block 44 needs to be rotated to reset, so that the rotating ring block 44 can engage the rotating block 49 and the clamping block 47 to limit the position, complete the locking, which is beneficial to construction safety. At the same time, during the movement of the protective shell seat 41, the staff can open the folding rod 413 horizontally, and use the locking rod 421 to clamp and fix the folding rod 413. The protective shell seat 41 is fixed on both sides by the folding rod 413 and the fixing rod 42, so that the force is evenly distributed, so as to prevent the shear force from being too strong and twisting the support frame 2 under complex terrain. , and while the folding rod 413 is horizontally unfolded, the sliding rod 418 fixed on the folding rod 413 is driven to approach the direction of the arc guide plate 415, so that the rotating rod 417 rotates, and the pressing plate 416 and the arc guide plate 415 are synchronously pressed down by the rotating rod 417 to stretch the first spring 414. After the arc guide plate 415 is pressed down, it always slides with the protective shell seat 41 to limit the position. Similarly, the sliding rod 418 on the other side is squeezed and pushed by the folding rod 413 to stretch the second spring 420, so that The arc guide plate 415 on the other side also moves downward, so that the arc guide plate 415 moves downward horizontally and close to the ground. The arc on the surface of the arc guide plate 415 can be used as protection and guidance to push away the gravel and soil in front of the crawler 3 in advance, thereby assisting the crawler 3 to travel smoothly. During construction, the folding rod 413 needs to be rotated and retracted to fit the protective shell seat 41, and then the second spring 420 drives the rotating rod 417 to reset. The arc guide plate 415 moves upward under the elastic force of the first spring 414 without hindering the leveling of the device.

[0052] Please refer to the above working process Figures 1 to 7 , Fig. 9 .

[0053] Furthermore, when the drilling position is selected and drilling is ready, the crawler 3 is driven by the external control system to move the drilling platform body 1 to the specified position, and then the double-headed cylinders 51 on both sides are started, so that the output end of the branch pipe 52 simultaneously pushes the first inclined block 53 to move in the direction of the second inclined block 55. Under the limiting action of the four pairs of limiting grooves 58, the first inclined block 53 pushes the slide rod 54 to move downward in parallel and move in the direction of the second inclined block 55 at the same time, thereby increasing the oblique squeezing force on the double-headed pile 56. Then, under the limiting action of the inclined slider 57, the double-headed pile 56 is driven downward into the ground along its own inclination angle, so that the outer edge of the protective shell seat 41 is firmly connected to the ground to prevent the device from tipping over or supporting shaking. In addition, the inclined double-headed pile 56 reduces the pile driving resistance and improves the gripping ability. The two pile heads of the double-headed pile 56 increase the pile driving area and improve the stability.
