Description

Technical Field

[0001] The utility model relates to the technical field of geothermal well drilling equipment, in particular to a mobile drilling frame for geothermal well drilling. Background Art

[0002] Geothermal well drilling is an engineering technology specifically for the exploration and development of geothermal resources. This technology involves drilling deep wells in the earth's crust to reach the geological layers that store heat energy, thereby extracting geothermal resources for use.

[0003] Existing geothermal well drilling equipment is divided into two types: surface drilling and underground drilling. The advantage of underground drilling is that it reduces the drilling depth, thereby reducing the amount of work and the workload of the staff.

[0004] When drilling equipment is drilling underground, a rail car mobile frame is required to facilitate the movement or transfer of the entire equipment.

[0005] A rail vehicle disclosed in Chinese patent publication number CN221049679U can increase the overall structural strength and rigidity of the rail vehicle through a protective frame, thereby reducing deformation, distortion or vibration of the vehicle during operation and improving the stability and reliability of the transport vehicle.

[0006] However, compared with the existing technologies in related fields, drilling equipment needs to constantly adjust its position when drilling underground, and the existing drilling equipment is not convenient to adjust its position after being fixed on the rail car. At the same time, after the position is adjusted, it is easy to have an unbalanced center of gravity, there is a risk of rollover, and the safety is relatively low. Utility Model Content

[0028] As a preferred technical solution of the utility model, Figures 2 to 5 As shown, the adjusting component 6 includes a first screw rod 61 rotatably arranged inside the mounting box 41, and sliding rods 62 are fixedly arranged on the left and right sides inside the mounting box 41. The positions of the two sliding rods 62 of the mounting plate 42 and the accommodating box 43 are fixedly provided with sliding members 63 slidably connected thereto, and the mounting plate 42 and the accommodating box 43 are both threadedly connected to the first screw rod 61 through the meshing component 7. A motor 8 is fixedly installed at the rear end of the mounting box 41 corresponding to the position of the first screw rod 61, and the output end of the motor 8 passes through the mounting box 41 and is connected to the first screw rod 61. By using the driving component 5 and the adjusting component 6, it is convenient to quickly align the drilling rig on the mounting plate 42 with the drilling point and improve the drilling efficiency of the drilling rig. At the same time, gravity can be applied to the other side of the rail vehicle 2 through the counterweight block 44 inside the accommodating box 43 to ensure the balance of the rail vehicle 2 and prevent the rail vehicle 2 from tipping over.

[0029] As a preferred technical solution of the utility model, Figure 3 , Figure 6 and Figure 7As shown, the meshing assembly 7 includes a slider 71, and the two sliders 71 are fixedly arranged at the bottom of the mounting plate 42 and the accommodating box 43 respectively. The left and right sides of the slider 71 are slidably provided with a meshing clip 72, and the slider 71 is rotatably provided with a second screw rod 73. The two meshing clips 72 are both threadedly connected with the second screw rod 73. The first screw rod 61 and the second screw rod 73 are both left-handed and right-handed threaded rods. The meshing clip 72 has a thread groove 721 matching the first screw rod 61 at a position corresponding to the first screw rod 61, and a threaded hole 722 matching the second screw rod 73 at a position corresponding to the second screw rod 73. The slider 71 is in a T-shape, and the meshing clip 72 has a slide groove 723 matching the second screw rod 73 at a position corresponding to the slider 71. A knob 731 is fixedly provided at one end of the second screw rod 73. When the model or weight of the drilling rig changes, the second screw rod 73 is rotated by the knob 731, so that the two meshing clamps 72 move away from each other, and then the two meshing clamps 72 are separated from the first screw rod 61. At this time, the accommodating box 43 can be slid, so as to utilize the lever principle to ensure the balance of the rail vehicle 2. At the same time, when in use, the second screw rod 73 can be rotated in the opposite direction by the knob 731, so that the two meshing clamps 72 are close to each other, so that the two meshing clamps 72 clamp the first screw rod 61 to achieve the limitation of the first screw rod 61, and ensure the stability of the drilling rig when drilling in the tunnel, so that the device can be adapted to various models of drilling rigs.

[0030] The rail vehicle 2, motor 8 and drilling rig described in this application are well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

[0031] The working process is as follows:

[0032] S1. When using, Figure 1 and Figure 2 As shown, the drilling rig is mounted on a mounting plate 42, and then a counterweight 44 of appropriate weight is selected according to the weight of the drilling rig, and then the counterweight 44 is placed inside a receiving box 43;

[0033] S2, such as Figures 2 to 5 As shown, after the equipment is installed, the drilling rig is transferred to the designated drilling point by the rail vehicle 2, and then the mounting platform 3 is controlled to rotate by the driving assembly 5 so that the drilling head of the drilling rig is close to the drilling point;

[0034] S3, such as Figure 2 , Figure 3 and Figure 4As shown, when the drilling head approaches the drilling point, the motor 8 controls the first screw 61 to rotate, so that the mounting plate 42 and the receiving box 43 move away from each other, so that the mounting plate 42 drives the drilling head of the drilling rig to align with the drilling point. At this time, the counterweight block 44 inside the receiving box 43 will apply gravity to the other side of the rail car 2 to ensure the balance of the rail car 2 and prevent the rail car 2 from tipping over. Then, the drilling rig can be used to drill in the tunnel;

[0035] S4, such as Figures 1 to 5 As shown, after the drilling is completed, the drilling head of the drilling rig is reset, and then the first screw 61 is controlled by the motor 8 to rotate in the opposite direction, so that the mounting plate 42 and the receiving box 43 are close to each other, thereby reducing the space occupied by the drilling rig and the receiving box 43, and facilitating the movement of the rail vehicle 2 in the tunnel;

[0036] S5, such as Figure 3 , Figure 6 and Figure 7 As shown, when the model or weight of the drilling rig changes, the second screw rod 73 is rotated by the knob 731, so that the two engaging clamps 72 move away from each other, and then the two engaging clamps 72 are separated from the first screw rod 61. At this time, the accommodating box 43 can be slid, so as to utilize the lever principle to ensure the balance of the rail vehicle 2. At the same time, when in use, the second screw rod 73 can be rotated in the opposite direction by the knob 731, so that the two engaging clamps 72 are close to each other, so that the two engaging clamps 72 clamp the first screw rod 61, so as to limit the first screw rod 61 and ensure the stability of the drilling rig when drilling in the tunnel.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
