Description

Technical Field

[0001] The invention relates to the field of engineering drilling, and in particular to a drilling rig for a power pit foundation and an on-site installation method of the drilling rig for the power pit foundation. Background Art

[0002] The surface of the power pit base needs to be dug with a large diameter deep hole (according to the national standard, the diameter of the deep hole is 1.4 meters and the depth is 1.8 meters) for pouring cement to fix the pole or the foundation of the power tower. The traditional large-diameter hole digging method first drills a dense array of multiple small-diameter holes within the diameter range of the deep hole, and then digs through the small-diameter holes to obtain a large-diameter hole. The engineering survey drilling rig is often used to drill a single small-diameter hole on the surface, and to perform exploration and coring. The drilling work can be completed at one time using a drill rod with the same diameter as the small-diameter hole. In order to save costs, technicians in this field have tried to use an engineering survey drilling rig to complete the drilling of a dense array of small-diameter holes on the surface of the power pit base. However, after drilling a small-diameter hole, the prior art engineering survey drilling rig needs to move the drill rig crawler or adjust the overall position of the drill rig so that the drill rod is aligned with the next small-diameter hole, which makes the large-diameter hole digging work on the surface of the power pit base long and the process cumbersome. In particular, when drilling a small-diameter deep hole, the drill rod needs to be accurately aligned, and the direction of the drill rod needs to remain stable during the drilling process. These problems make the prior art engineering survey drilling rig unable to meet the working requirements of the power pit base occasion. Summary of the invention

[0042] The present invention will now be discussed with reference to several embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thus implement the present invention, rather than implying any limitation on the scope of the present invention.

Other explicit and implicit definitions may also be included below.

[0044] In the following description, some specific numerical values ​​or numerical ranges may be involved. It should be understood that these numerical values ​​and numerical ranges are merely exemplary, and they may be helpful in putting the idea of ​​the present invention into practice. However, the description of these examples is not intended to limit the scope of the present invention in any way. According to specific application scenarios and requirements, these numerical values ​​or numerical ranges can be set separately.

[0045] As mentioned above, the existing drilling rigs cannot meet the working requirements of power pit foundations. The drilling rig for power pit foundations and the on-site installation method of the drilling rig for power pit foundations proposed in the embodiments of the present invention at least partially solve the above problems. Figure 1-Figure 4 The technical concept and working principle of the power pit foundation drilling rig and the on-site installation method of the power pit foundation drilling rig according to the exemplary embodiment of the present invention are described. Figure 1-Figure 4 As shown, the electric power pit foundation drilling rig according to the embodiment of the present invention generally includes a base system, a first guide rail 21, a second guide rail 30, an intermediate frame 13, a base frame 33, a clean water tank 42, a mud tank 41, a diesel tank 43, an engine 44, a hydraulic oil tank 45 and a control console 46, a winch 53, a lifting frame and a power head 52, etc. Other conventional components of the prior art drilling rig are also included in the embodiment of the present invention, which will not be repeated here. Among them, the base system is composed of a frame 11 and a base plate 12. The frame 11 is used to bear the weight of the entire power pit foundation 01 drilling rig, and provides a bearing function during position adjustment and drilling. The base plate 12 is used to place drilling rig components such as a clean water tank 42, a mud tank 41, a diesel tank 43, an engine 44, a hydraulic oil tank 45 and a control console 46, providing a stable and flexible placement space for these drilling rig components; the first guide rail 21 provides a moving guide for the power head 52 along the two sides of the drilling rig, and the second guide rail 30 provides a moving guide for the power head 52 along the front and rear directions of the drilling rig. The intermediate frame is used for transition connection between the first guide rail 21 and the second guide rail 30; the base frame 33 is used to carry components such as the lifting frame, the power head 52 and the winch 53.

[0046] The frame 11 is the base of the entire drilling rig, and needs to provide sufficient placement space for other components and provide sufficient bearing strength. In one embodiment, the frame 11 is formed of a regular quadrilateral by splicing profiles together, and the four profiles of the quadrilateral are orthogonal to each other. Then, the strip-shaped rectangular substrate 12 is matched, so that the substrate 12 can be supported by three profiles at the same time, ensuring the horizontality, bearing strength and bearing stability of the substrate 12. Exemplarily, the profile constituting the frame 11 can be selected from I-beams, and the wing plates of the I-beams can be used to stably support the substrate 12. Even if the substrate 12 is only placed on the wing plates of the I-beams without any connection measures, it can be ensured that there is no movement between the substrate 12 and the frame 11, thereby improving the on-site installation speed of the drilling rig.

[0047] The first guide rail 21 is directly connected to the frame 11, and three mutually parallel first guide rails 21 are provided. The extension direction of the first guide rail 21 is consistent with the direction of the two sides of the drilling rig. In one embodiment, the two ends of the strip-shaped guide seat 211 are respectively connected to the frame 11, for example, by bolt connection. The upper surface of the guide seat 211 is flat, and the rail portion 213 is provided on the upper surface of the guide seat 211 and fixedly connected. At the same time, the substrate 12 can also be overlapped on the upper surface of the guide seat 211 to further provide a bearing effect for the substrate 12. In another embodiment, the length of the rail portion 213 is only the distance between the side surfaces of the substrates 12 on both sides, and a limit block 212 is provided between the end of the rail portion 213 and the side surface of the substrate 12, so as to limit the rail portion 213 and the substrate 12 respectively in the direction of the two sides of the drilling rig.

[0048] The intermediate frame 13 is slidably arranged on the first guide rails 21 through a sliding assembly. Since three first guide rails 21 are arranged, the intermediate frame 13 is slidably connected to the three first guide rails 21 through three pairs of sliding assemblies. In one embodiment, the intermediate frame 13 is composed of a pair of main beams 31 extending in the front-rear direction of the drilling rig, and auxiliary beams 32 extending in the two sides of the drilling rig. The two ends of the auxiliary beams 32 are respectively connected to the pair of main beams 31. The number of auxiliary beams 32 can be one pair, three or more. For example, a pair of auxiliary beams 32 are respectively connected to the main beams 31 near the front and near the rear of the drilling rig, so that a rectangular frame is formed by the main beams 31 and the auxiliary beams 32. In another example, the third auxiliary beam 32 is arranged near the middle position to further improve the structural strength of the intermediate frame 13. Since the lifting frame 51 has a large size in the front-to-rear direction of the drilling rig, in order to ensure that the lifting frame 51 still has room to move in the front-to-rear direction of the drilling rig, the above-mentioned main beam 31 and auxiliary beam 32 are used to form a structure so that the intermediate frame 13 has a large size in the front-to-rear direction of the drilling rig while still having sufficient structural strength, thereby preventing the intermediate frame 13 from deforming during the drilling process of the small-diameter deep hole 02.

[0049] A pair of second guide rails 30 are arranged above the intermediate frame 13, and the extension direction of the second guide rails 30 is consistent with the front-rear direction of the drilling rig. In one embodiment, the second guide rails 30 can be directly arranged on the upper surface of a pair of main beams 31, and the main beams 31 can provide a higher structural strength for the second guide rails 30 to ensure that the second guide rails 30 are not deformed. Exemplarily, the main beams 31 and the auxiliary beams 32 can be made of I-beams, and the second guide rails 30 are directly arranged on the upper surface of the wing plates of the I-beams.

[0050] The base frame 33 is slidably arranged on the second guide rail 30 through a sliding assembly, so that the base frame 33 drives the lifting frame 51, the power head 52 and other components to move along the front and rear directions of the drilling rig. In one embodiment, a pair of front sliding support points a and a pair of rear sliding support points b are arranged between the base frame 33 and the second guide rail 30. During the drilling of the small-diameter deep hole 02, the reaction force borne by the drill rod is transmitted to the intermediate frame 13 through the front sliding support points a and the rear sliding support points b. That is to say, the intermediate frame 13 is subjected to the largest load at the positions of the front sliding support points a and the rear sliding support points b, and is most susceptible to deformation.

[0051] In order to avoid structural deformation and ensure the stability of the drill rod direction during the drilling of the small-diameter deep hole 02, the three first guide rails 21 are arranged at intervals along the front-to-back direction of the drilling rig, wherein the first guide rail 21 located in the middle is set as the first guide rail 21 located closer to the rear of the drilling rig, thereby ensuring that the front sliding support point and the rear sliding support point of the base frame 33 are across the middle first guide rail 21 at any position within the moving range of the drilling rig in the front-to-back direction, thereby ensuring the structural stability of the intermediate frame 13. Exemplarily, the spacing between the three first guide rails 21 is arranged in parallel from front to back at L1:L2=3:2, so that the position of the middle first guide rail 21 contributes optimally to the improvement of the structural stability of the intermediate frame 13.

[0052] In one embodiment, when the intermediate frame 13 is provided with three attachment beams 32 , the positions of the three attachment beams 32 correspond to the positions of the three first guide rails 21 , thereby resisting the bearing force of the first guide rails 21 on the intermediate frame 13 and improving the structural strength of the intermediate frame 13 .

[0053] The sliding settings between the base frame 33 and the second guide rail 30, and between the intermediate frame 13 and the first guide rail 21 are all realized by sliding components, some or all of which include a slide seat 331, a slider 332 and a locking pin 333. The slider 332 is set at the bottom of the slide seat 331, and the locking pin 333 is set on the slide seat 331. The first guide rail 21 is tightened by the locking pin 333, thereby realizing the locking between the intermediate frame 13 and the first guide rail 21.

[0054] In one embodiment, the clear water tank 42 and the mud tank 41 are stacked on the base plate 12 in the area on one side of the drilling rig, and the diesel tank 43, the engine 44, the hydraulic oil tank 45 and the control console 46 are sequentially arranged from back to front on the base plate 12 in the area on the other side of the drilling rig, so that the reaction force on the drill rod when drilling into the front, rear and side small-diameter deep holes 02 is balanced with the weight of the components placed on the base plates 12 on both sides in the front and rear directions of the drilling rig and in the directions on both sides of the drilling rig. It should be noted that the arrangement of components in the embodiment of the present invention meets the weight of the component models commonly selected for industrial exploration drilling rigs on the market.

[0057] S2, three first guide rails 21 extending along the two sides of the drilling rig are installed in the frame 11, and the three first guide rails 21 are parallel to each other and arranged at intervals along the front-rear direction of the drilling rig;
