Description

Technical Field

[0001] The utility model relates to the technical field of geological drilling, in particular to a supporting structure used for geological drilling. Background Art

[0002] Geological drilling refers to the use of deep drilling mechanical engineering technology to mine underground or other natural resources, or to take actual cross-sections of strata and extract physical samples to provide experiments to obtain relevant data. In geotechnical engineering surveys, geological drilling can directly obtain samples of rock and soil layers at different depths underground.

[0003] Geological drilling rigs will generate strong impact force and continuous vibration during operation. If there is a lack of effective support, the rig will easily move, shake or even fall on the ground, which will not only seriously affect the accuracy of drilling, but also lead to problems such as borehole position offset and depth error, making the acquired geological samples unrepresentative and unable to provide reliable data for subsequent projects. It may also cause safety accidents and cause personal injury to on-site operators. By supporting the rig, the huge pressure generated by the rig during operation can be dispersed, allowing the rig to maintain stable contact with the ground, reducing the risk of instability caused by soft and uneven ground under complex geological conditions. A good support structure can also buffer the vibration of the rig to a certain extent, reduce the loss of vibration to the precision components inside the equipment, extend the service life of the rig, and ensure that the drilling work is carried out efficiently and stably.

[0004] After searching, the existing patent authorization announcement number: CN221856643U discloses a support structure and geological drilling device used for geological drilling, including a mounting plate, a drilling rig is detachably mounted in the middle of the mounting plate, a drill bit is detachably connected to the working end of the drilling rig, a positioning mechanism is fixedly connected to the top of the mounting plate, and two support plates are fixedly connected to the bottom of the mounting plate. The two support plates are symmetrically arranged on both sides of the working end of the drilling rig, which can improve the stability of the drilling device during operation.

[0005] The above-mentioned device fixes the drilling rig through a positioning ring, and the positioning ring is prone to deformation in a vibrating environment. Since the positioning ring is fixed in size and lacks an adjustable design, when subjected to high-frequency vibration shocks from the drilling process, the internal stress distribution of the structure is uneven. In the stress concentration area, microcracks will gradually appear on the positioning ring, eventually leading to structural deformation. Continuous and strong vibrations will be generated during geological drilling. If the device is in such a vibrating environment for a long time, the hinge shaft in the device is prone to loosening, and its loosening will destroy the stability of the entire supporting structure. The above-mentioned device does not lack secondary protection function. When the positioning rod is damaged, it will lose support for its top. Utility Model Content

[0006] The utility model aims to provide a supporting structure for geological drilling, which can solve the problem that the above-mentioned device fixes the drilling rig by a positioning ring of fixed size, and the positioning ring of fixed size is very easy to deform in a vibration environment. Since the positioning ring is fixed in size and lacks an adjustable design, when subjected to high-frequency vibration impact from the drilling process, the internal stress distribution of the structure is uneven. In the stress concentration area, micro cracks will gradually appear in the positioning ring, which will eventually lead to structural deformation. Continuous and strong vibrations will be generated during the geological drilling process. In such a vibration environment for a long time, the hinge shaft in the device is prone to loosening, and its loosening will destroy the stability of the entire supporting structure.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a support structure used for geological drilling, comprising support legs, and also comprising a fixing mechanism arranged outside the end of the support legs;

[0008] The fixing mechanism includes a fixing frame, which is arranged on one side of the supporting leg, and a plurality of groups of connecting plates are annularly fixedly connected to the inner side of the end of the fixing frame, sliding columns are fixedly connected to the outer sides of both ends of the connecting plates, and clamping blocks are slidably connected to the outer sides of the sliding columns, and two first rotating arms are rotatably connected to one side of the connecting plate, and the inner side of the end of the first rotating arm is rotatably connected to the second rotating arm, and the connection between the first rotating arm and the second rotating arm is rotatably connected to the third rotating arm, and the inner side of the end of the third rotating arm is rotatably connected to the connecting block, and an adjustment component is arranged on one side of the supporting leg.

[0009] As a preferred embodiment, a telescopic cylinder is installed on one side of the connecting plate, and the outer side of one end of the telescopic cylinder is fixedly connected to one side of the connecting block.

[0010] As a preferred implementation, one side of the clamping block is provided with an arc structure.

[0011] As a preferred implementation, a limiting block is fixedly connected to the outer side of one end of the sliding column.

[0012] As a preferred embodiment, the clamping blocks are arranged in four groups in a ring shape inside the fixing frame, and their arc-shaped structures form a complete circle.

[0013] As a preferred embodiment, the adjustment assembly includes a slider, which is slidably connected to the inner side of one end of the supporting leg. The inner side of the end of the supporting leg is rotatably connected to a threaded rod, and the outer side of the threaded rod is threadedly connected to the inner side of one end of the slider.

[0014] As a preferred implementation, a motor is installed on the outer side of one end of the supporting leg, and the outer side of the main shaft of the motor is fixedly connected to the outer side of one end of the threaded rod.

[0015] As a preferred implementation, a plurality of conical blocks are fixedly connected to the outer side of the bottom end of the support leg.

[0016] Compared with the prior art, the advantages and positive effects of the utility model are:

[0017] 1. The utility model, when in use, ensures that the geological drilling device can be stably clamped even when it vibrates through the self-locking function of the clamping device. The self-locking support design reduces the damage to the connection of the device and the telescopic cylinder caused by vibration, greatly improves the stability and reliability of the support, and ensures the smooth progress of the drilling work. The large-area arc structure on one side of the clamping block can fit the outer side of the geological drilling device to provide stable support for it, further enhances the overall support effect, disperses the pressure of the drilling device, prevents uneven stress distribution, reduces local excessive force, and extends the service life of the device. At the same time, when the telescopic cylinder fails, the self-locking function of the device can ensure the clamping force and reduce the occurrence of accidents. At the same time, the fixing mechanism of the device can quickly disassemble and fix the drilling rig machinery, which increases the convenience of using the device.

[0018] 2. When the utility model is in use, the user starts the motor to drive the threaded rod to rotate, thereby causing the slider threadedly connected to the threaded rod to move in the vertical direction on the inner side of the end of the support leg, thereby driving the clamped geological drilling device to move in the vertical direction. The height position of the geological drilling device can be flexibly adjusted to meet the height requirements of different drilling operations, thereby increasing the flexibility and adaptability of the device. The conical block can increase the friction between the device and the ground, which makes the supporting structure more stable during operation and reduces the shaking or displacement of the device caused by factors such as ground conditions or vibrations generated by drilling operations, thereby ensuring the smooth progress of geological drilling work, improving the accuracy and safety of drilling, and also reducing the risk of damage to the drilling equipment due to device instability.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 - Figure 4 The utility model provides a technical solution: a support structure used for geological drilling, including a support leg 1, and also including a fixing mechanism 2 arranged on the outer side of the end of the support leg 1, the fixing mechanism 2 includes a fixing frame 21, the fixing frame 21 is arranged on one side of the support leg 1, and the inner side of the end of the fixing frame 21 is annularly fixedly connected with multiple groups of connecting plates 22, the outer sides of both ends of the connecting plates 22 are fixedly connected with sliding columns 23, the outer side of the sliding column 23 is slidably connected with a clamping block 24, one side of the connecting plate 22 is rotatably connected with two first rotating arms 25, and the inner side of the end of the first rotating arm 25 is rotatably connected with a second The rotating arm 26, the first rotating arm 25 and the second rotating arm 26 are rotatably connected to the third rotating arm 27 at the connection point, and the inner side of the end of the third rotating arm 27 is rotatably connected to the connecting block 28. An adjustment component is provided on one side of the supporting leg 1, and a telescopic cylinder 29 is installed on one side of the connecting plate 22. The outer side of one end of the telescopic cylinder 29 is fixedly connected to one side of the connecting block 28. An arc structure is provided on one side of the clamping block 24, and the outer side of one end of the sliding column 23 is fixedly connected to the limiting block 210. The clamping block 24 is provided with four groups in a ring shape on the inner side of the fixed frame 21, and its arc structure forms a complete circle.

[0028] When the user uses the device, the device can be transferred to a designated position. At this time, the user can place the geological drilling device that needs to be supported on the inner side of the multiple clamping blocks 24 and start the telescopic cylinder 29 at the same time. The length of the telescopic cylinder 29 increases, and at the same time, the connecting block 28 at its end is driven to move. When the connecting block 28 moves, it pushes the third rotating arm 27 to both sides. The third rotating arm 27 rotates a certain angle on both sides of the connecting block 28. At the same time, the other end of the third rotating arm 27 pushes one side of the first rotating arm 25 and the second rotating arm 26 until the first rotating arm 25 and the second rotating arm 26 are pushed to the same vertical axis. At this time, the two third rotating arms 27 are on the same axis, so the first rotating arm 25 and the second rotating arm 26 have no component force in the tilting direction. At the same time, the third rotating arm 27 It is in a vertical state with the first rotating arm 25 and the second rotating arm 26, and the self-locking function of the clamping device is realized. Therefore, the geological drilling device can be stably clamped when it vibrates. The large-area arc structure on one side of the clamping block 24 can stably support the outside of the geological drilling device. The self-locking function of the clamping of the device ensures that the geological drilling device can be stably clamped when it vibrates, greatly improving the stability and reliability of the support, effectively preventing the geological drilling device from shaking or shifting during operation, and ensuring the smooth progress of the drilling work. The large-area arc structure on one side of the clamping block 24 can fit the outside of the geological drilling device and stably support it, further enhancing the overall support effect, dispersing the pressure of the drilling device, reducing the situation of excessive local force, and extending the service life of the device.

[0029] like Figure 1 - Figure 4 As shown, the adjustment assembly includes a slider 211, which is slidably connected to the inner side of one end of the supporting leg 1, and a threaded rod 212 is rotatably connected to the inner side of the end of the supporting leg 1. The outer side of the threaded rod 212 is threadedly connected to the inner side of one end of the slider 211, and a motor 213 is installed on the outer side of one end of the supporting leg 1. The outer side of the main shaft of the motor 213 is fixedly connected to the outer side of one end of the threaded rod 212, and a plurality of conical blocks 214 are fixedly connected to the outer side of the bottom end of the supporting leg 1.

[0030] When the user starts the motor 213, the threaded rod 212 can be driven to rotate, thereby causing the slider 211 threadably connected to the threaded rod 212 to move vertically on the inner side of the end of the support leg 1, thereby driving the clamped geological drilling device to move in the vertical direction. The height position of the geological drilling device can be flexibly adjusted to meet the height requirements of different drilling operations, thereby increasing the flexibility and adaptability of the device. The conical block 214 can increase the friction between the device and the ground, which makes the support structure more stable during operation and reduces the shaking or displacement of the device caused by factors such as ground conditions or vibrations generated by drilling operations, thereby ensuring the smooth progress of geological drilling work, improving the accuracy and safety of drilling, and also reducing the risk of damage to the drilling equipment due to device instability.

[0031] Working principle: When using the device, the user can move the device to a designated position. At this time, the user can place the geological drilling device that needs to be supported on the inner side of the multiple clamping blocks 24, and start the telescopic cylinder 29 at the same time. The length of the telescopic cylinder 29 increases, and at the same time, the connecting block 28 at its end is driven to move. When the connecting block 28 moves, it pushes the third rotating arm 27 to both sides. The third rotating arm 27 rotates at a certain angle on both sides of the connecting block 28, and at the same time, the other end of the third rotating arm 27 pushes one side of the first rotating arm 25 and the second rotating arm 26 until the first rotating arm 2 5 and the second rotating arm 26 are pushed to the same vertical axis. At this time, the two third rotating arms 27 are on the same axis, so the first rotating arm 25 and the second rotating arm 26 have no component force in the tilting direction. At the same time, the third rotating arm 27 is in a vertical state with the first rotating arm 25 and the second rotating arm 26, realizing the self-locking function of the device. Therefore, the geological drilling device can be stably clamped when it vibrates. The large-area arc structure on one side of the clamping block 24 can stably support the outer side of the geological drilling device. The self-locking function of the device ensures that the geological drilling device can be stably clamped when it vibrates. The stability and reliability of the support are greatly improved, and the shaking or displacement of the geological drilling device during operation is effectively prevented, so as to ensure the smooth progress of the drilling work. The large-area arc structure on one side of the clamping block 24 can fit the outer side of the geological drilling device to provide stable support for it, further enhancing the overall support effect, dispersing the pressure of the drilling device, reducing the situation of excessive local force, and extending the service life of the device. When the user starts the motor 213, the threaded rod 212 can be driven to rotate, so that the slider 211 threadedly connected to the threaded rod 212 is vertically moved on the inner side of the end of the support leg 1. The geological drilling device can be moved in a vertical direction to drive the clamped geological drilling device to move. The height position of the geological drilling device can be flexibly adjusted to meet the height requirements of different drilling operations, thereby increasing the flexibility and adaptability of the device. The conical block 214 can increase the friction between the device and the ground, which makes the support structure more stable during operation and reduces the shaking or displacement of the device caused by factors such as ground conditions or vibrations generated by drilling operations, thereby ensuring the smooth progress of geological drilling work, improving the accuracy and safety of drilling, and also reducing the risk of damage to the drilling equipment due to unstable devices.
