Description

Technical Field

[0001] This invention relates to the field of geological exploration equipment technology, and in particular to a geological prediction device and its usage method for the construction of steel casing for pile foundations in inclined rock areas. Background Technology

[0002] Geological and mineral exploration is based on advanced geological science theories. It relies on extensive field geological observations and the collection and organization of relevant geological data. It employs comprehensive geological methods and techniques, including geological surveying, geophysical and geochemical exploration, and drilling, to obtain reliable geological and mineral information. Geological and mineral exploration can utilize industrial microscopes to observe and test the structure of soil layers. Soil can be classified according to its depositional age as old deposited soil, general deposited soil, and recently deposited soil; according to particle size distribution or plasticity index as gravelly soil, sandy soil, silty soil, and clayey soil; according to organic matter content as inorganic soil, organic soil, carbonaceous soil, and peat; and according to engineering geological significance and the soil's special composition, state, and structural characteristics, it can be further classified as disintegrating soil, soft soil, expansive soil, saline soil, and artificial fill, etc.

[0003] Before constructing steel casing pile foundations in sloping rock areas, geological exploration is required. Existing equipment involves drilling holes with drilling rigs to collect soil samples. However, after collecting the soil samples, the existing sampling device requires manual disassembly of the drill rod, followed by hammering to extract the soil sample. This increases labor costs and slows down the sampling process. Furthermore, this method can damage the soil sample, affecting subsequent predictions and the assessment of the geology of the sloping rock area, leading to errors in the assessment and impacting later construction. Finally, the collected soil sample cannot be removed in advance; the drill rod must be raised to retrieve it, making it impossible to perform timed sampling based on the drilling depth for easy observation. Summary of the Invention

[0004] Based on the existing problems of existing geological prediction equipment, which involves removing soil samples by tapping, affecting the sampling speed, easily damaging the soil samples, affecting the prediction results, and impacting subsequent construction, and failing to automatically remove soil samples according to the situation, this invention proposes a geological prediction equipment and its usage method for pile foundation steel casing construction in inclined rock areas.

[0005] The present invention proposes a geological prediction device for the construction of steel casing for pile foundations in inclined rock areas, which includes a drive vehicle, an adjustment device, a drilling device, and a data acquisition device installed on the outer surface of the drive vehicle.

[0006] An adjustment device is located on the outer surface of the drive vehicle and adjusts the angle between the drill holes. The adjustment device includes an adjustment mechanism and a support mechanism. The adjustment mechanism includes a telescopic hydraulic cylinder, which adjusts the angle of the drilling device by telescopically extending and retracting. The support mechanism includes support feet, which support the drilling device.

[0007] A drilling device is located on the outer surface of the drive vehicle and drills holes in the ground. The drilling device includes a lifting mechanism and a drilling mechanism. The lifting mechanism includes a sliding plate. The movement of the sliding plate drives the drilling mechanism to rise and fall. The drilling mechanism includes an outer drill rod. The rotation of the outer drill rod drills holes in the ground.

[0008] A collection device is located inside the drilling device and collects soil after drilling. The collection device includes a collection mechanism and a conveying mechanism. The collection mechanism includes a separation plate, the rotation of which separates the columnar soil sample. The conveying mechanism includes a conveying plate, the movement of which fixes the collected soil.

[0009] Preferably, the adjustment mechanism further includes a support frame, the outer surface of which is hinged to the outer surface of the vehicle frame via a pin, the telescopic hydraulic cylinder being hinged to the outer surface of the vehicle frame via a pin, and one end of the telescopic hydraulic cylinder being hinged to the outer side of the support frame via a pin.

[0010] The above technical solution allows the support frame to be adjusted to remain perpendicular to the ground by the push of the telescopic hydraulic cylinder, facilitating the adjustment of the drilling angle.

[0011] Preferably, the support mechanism further includes a bracket, which is fixedly installed on the outer surface of the support frame. A support hydraulic cylinder is fixedly installed on the lower surface of the bracket. One end of the piston rod of the support hydraulic cylinder is hinged to one end of the support foot by a pin. A fixing nail is fixedly installed on the lower surface of the support foot.

[0012] The above technical solution uses a hydraulic cylinder to move the support frame, which can be adjusted to fit the ground according to the terrain, thus supporting the drilling device. The fixing nails can be inserted into the soil to stabilize the support feet.

[0013] Preferably, the lifting mechanism further includes a lead screw, which is fixedly installed on the outer surface of the support frame via bearings. A lifting motor is fixedly installed on the upper surface of the support frame. One end of the output shaft of the lifting motor is fixedly installed to one end of the lead screw via a coupling. The sliding plate is slidably inserted into the outer surface of the support frame, and the outer side of the sliding plate is threadedly connected to the outer surface of the lead screw.

[0014] The above technical solution enables the external drill rod to descend during rotation by rotating the lead screw, facilitating the drilling action.

[0015] Preferably, the drilling mechanism further includes a drilling motor, which is fixedly mounted on the outer surface of the slide plate. One end of the outer drill rod is fixedly mounted to the upper surface of the slide plate via a bearing. An outer drill bit is fixedly mounted on the lower end of the outer drill rod. An inner drill rod is fixedly mounted on the outer surface of the slide plate via a bearing. An inner drill bit is rotatably connected to one end of the inner drill rod. The outer surface of the inner drill bit is fixedly mounted to the inner wall of the outer drill bit. A drive gear is fixedly mounted on one end of the output shaft of the drilling motor. A transmission gear is fixedly mounted on one end of the outer drill rod. A moving gear is slidably inserted into the outer surface of the inner drill rod. A moving electromagnet is fixedly mounted on the outer surface of the inner drill rod. The outer surface of the moving electromagnet is magnetically connected to the lower surface of the moving gear via an adsorption element. A connecting spring that forces the moving gear to reset is fixedly mounted on the outer surface of the inner drill rod. The two drive gears mesh with the transmission gear and the moving gear, respectively.

[0016] With the above technical solution, by fixing the inner drill bit and the outer drill bit, the rotation of the outer drill bit can drive the outer drill bit to rotate. The rotation of the outer drill bit, in conjunction with the drilling of the inner drill bit, facilitates sampling. Holes can be opened on the outer drill rod to facilitate the transportation and circulation of mud. Mud can enter through the space between the inner and outer drill rods and flow out through the holes on the outer drill rod.

[0017] Preferably, the acquisition mechanism further includes a guide rail, which is fixedly installed on the inner wall of the inner drill rod. An acquisition housing is slidably inserted into the outer surface of the guide rail. A drive ring with toothed grooves is rotatably connected to the inner wall of the acquisition housing. The inner wall of the acquisition housing is hinged to one end of the separation plate. The toothed grooves of the separation plate mesh with the toothed grooves of the drive ring. A separation drill bit is fixedly installed at one end of the separation plate.

[0018] Through the above technical solution, the rotation of the drive ring can drive the separation plate to deflect, so that when the separation plate is retracted, it can not affect the rise of the soil sample. After the separation plate is deflected, the separation drill bit can cut and separate the soil sample. The rotation of the separation plate can complete the cutting action.

[0019] Preferably, a data acquisition motor is fixedly installed on the outer side of the data acquisition housing, and a deflection gear is fixedly installed at one end of the output shaft of the data acquisition motor, the deflection gear meshing with the tooth groove of the drive ring.

[0020] Through the above technical solution, in order to automatically drive the separation plate to deflect, the motor is started to drive the deflection gear to rotate, and the rotation of the deflection gear can drive the drive ring to rotate.

[0021] Preferably, the conveying mechanism further includes a conveyor housing, the outer surface of which is fixedly installed with the outer surface of the collection housing, a conveying motor is fixedly installed on the upper surface of the conveyor housing, one end of the output shaft of the conveying motor passes through the upper surface of the conveyor housing and a conveying gear is fixedly installed thereon, and a conveying rack is fixedly installed on the outer surface of the guide rail, the conveying gear meshing with the conveying rack.

[0022] With the above technical solution, after the conveyor motor is started, it can drive the conveyor gear to rotate on the conveyor rack, thereby driving the conveyor housing to rise. This allows the conveyor housing to carry the soil samples that have been divided on the collection housing to rise, and automatically transport the soil samples without having to remove the drill rod first.

[0023] Preferably, an adsorption electromagnet is fixedly installed on the upper surface of the acquisition housing, the outer surface of the adsorption electromagnet is slidably inserted into the outer surface of the conveying plate, the outer surface of the adsorption electromagnet is magnetically connected to the outer surface of the conveying plate, and a return spring is fixedly installed on the outer surface of the conveying plate, with one end of the return spring fixedly installed on the outer surface of the adsorption electromagnet.

[0024] The above technical solution allows the electromagnet to be energized to attract the conveyor plate, facilitating the removal of soil samples. The return spring helps the conveyor plate to return to its original position, and multiple conveyor plates are arranged in a tubular shape to facilitate the fixation of the soil sample.

[0025] The present invention proposes a method for using a geological prediction device for steel casing construction of pile foundations in inclined rock areas, comprising the following steps:

[0026] S1: When geological exploration is required in a sloping rock area, the vehicle is moved to the location to be explored and then fixed. When geological samples are to be collected, the support frame is pulled by the telescopic hydraulic cylinder to keep the support frame perpendicular to the ground to be sampled. At the same time, the support hydraulic cylinder on the support pushes the support foot to contact the ground. The support foot automatically adjusts the angle to keep it in contact with the ground, so that the fixing nail is pressed into the ground to keep the support frame stable.

[0027] S2: Start the lifting motor on the support frame. The lifting motor drives the lead screw to rotate, causing the slide plate to slide downward on the support frame. At the same time, the drilling motor starts, driving the drive gear to rotate. The rotation of the drive gear drives the transmission gear meshing with it to rotate. After the transmission gear drives the outer drill rod to rotate, the outer drill bit and inner drill bit below the outer drill rod rotate to drill a hole in the ground. At the same time, the soil in the center of the hole can enter the center of the collection housing through the center hole of the inner drill bit. It enters the circular tube surrounded by the conveying plate through the center of the collection housing. As the outer drill rod descends, the soil inside rises.

[0028] S3: After reaching the set depth, the acquisition motor on the acquisition housing is started. The acquisition motor drives the deflection gear to rotate, which in turn drives the drive ring to rotate. This causes the separation plate to deflect relative to the deflection. At the same time, after the moving electromagnet is energized, it attracts the moving gear, allowing the moving gear to mesh with another drive gear. The rotation of the drive gear drives the rotation of the inner drill rod. The inner drill rod, through the conveyor housing that is slidably inserted with it, drives the acquisition housing to deflect. This causes the separation drill bit to cut and separate the sample collected at the center of the acquisition housing. As the separation plate deflects, the samples above and below the separation plate are separated.

[0029] S4: After separation is completed, the moving electromagnet is de-energized, the connecting spring resets the moving gear, the inner drill rod stops rotating, and the conveyor motor on the conveyor housing starts and drives the conveyor gear to rotate. The rotating conveyor gear rotates on the conveyor rack and drives the conveyor housing to rise. The conveyor housing rises on the guide rail and carries the soil collected above the separation plate. After leaving the inner drill rod, the soil is collected by energizing the adsorption electromagnet, the reset spring is compressed, and the adsorption electromagnet adsorbs the conveyor plate. The sample between the conveyor plates can be collected manually by the collection box.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. By setting up a drilling device, drilling can be performed automatically. The rotation of the lead screw drives the outer drill rod to descend. The outer drill rod can be rotated under the control of the drive motor. Through the cooperation of the outer drill bit and the inner drill bit, the soil geology can retain the part that needs to be sampled, which is convenient for sampling. The inner drill rod can be selectively rotated by the control of the moving electromagnet. The rotation of the inner drill rod can drive the sampling device to rotate, realizing the segmentation of soil samples.

[0032] 2. By setting up a sampling device, soil samples can be separated for easy transport. The rotation of the separation plate drives the rotation of the separation drill bit, and the separation plate can also deflect to complete the segmentation of the soil sample, facilitating its ascent. When the separation plate closes, it supports the soil sample. The separation plate deflects through the rotation of the drive ring, thereby cutting and separating the soil sample. The drive ring is driven by a collection motor, enabling automatic operation. This improves sampling efficiency, reduces damage to the soil sample, and solves the technical problem in existing geological prediction equipment where soil samples are extracted by tapping, which affects sampling speed, easily damages the soil sample, and impacts subsequent prediction results and construction.

[0033] 3. By setting up a sampling device, soil samples can be automatically transported. When the conveyor motor is started, the conveyor gear rotates on the conveyor rack, driving the conveyor housing to rise, thereby automatically transporting the soil sample from the collection housing. In addition, an electromagnet is installed on the upper surface of the collection housing to attract the conveyor plate for easy removal of the soil sample. A return spring is installed on the conveyor plate to reset it. Multiple conveyor plates are arranged in a tubular shape to facilitate fixing the soil sample, thus making the soil sample collection and transportation process more automated and efficient, solving the technical problem that existing geological prediction equipment cannot automatically remove soil samples according to the situation.

[0058] Reference Figures 1-10 A method for using a geological prediction device for steel casing construction of pile foundations in inclined rock areas includes the following steps:

[0059] S1: When geological exploration is required in the sloping rock area, after the drive vehicle 1 is moved to the location to be explored, the drive vehicle 1 is fixed. When geological samples need to be collected, the support frame 2 is pulled by the telescopic hydraulic cylinder 21 so that the support frame 2 is kept perpendicular to the ground to be sampled. At the same time, the support hydraulic cylinder 31 on the bracket 3 pushes the support foot 32 to contact the ground.

At the same time, the soil in the center of the hole can enter the center of the collection housing 61 through the center hole of the inner drill bit 54. It enters the circular tube surrounded by the conveying plate 81 through the center of the collection housing 61. As the outer drill rod 51 descends, the soil inside rises.

[0061] S3: After reaching the set depth, the acquisition motor 65 on the acquisition housing 61 is started. The acquisition motor 65 drives the deflection gear 66 to rotate, and the deflection gear 66 drives the drive ring 62 to rotate, which can drive the separation plate 63 to deflect relative to each other. At the same time, after the moving electromagnet 58 is energized, it attracts the moving gear 57, so that the moving gear 57 can mesh with another drive gear 55. The rotation of the drive gear 55 can drive the rotation of the inner drill rod 53. The inner drill rod 53 drives the acquisition housing 61 to deflect through the conveyor housing 7 that is slidably inserted with it, and drives the separation drill bit 64 to cut and separate the sample collected at the center of the acquisition housing 61. With the deflection of the separation plate 63, the samples above and below the separation plate 63 can be separated.

[0062] S4: After separation is completed, the moving electromagnet 58 is de-energized, the connecting spring 59 resets the moving gear 57, the inner drill rod 53 stops rotating, the conveyor motor 71 on the conveyor housing 7 starts and drives the conveyor gear 72 to rotate. The conveyor gear 72 rotates on the conveyor rack 73 and drives the conveyor housing 7 to rise. The conveyor housing 7 rises on the guide rail 6. After the soil collected above the separation plate 63 rises and leaves the inner drill rod 53, the soil is collected by the collection box between the conveyor plates 81. After the electromagnet 8 is energized, the reset spring 82 is compressed and the electromagnet 8 attracts the soil. The collection electromagnet 8 can then collect the soil between the conveyor plates 81 manually.

6. A method for using a geological prediction device for steel casing construction of pile foundations in inclined rock areas, as described in claim 5, comprising the following steps: S1: When geological exploration is required in the sloping rock area, the drive vehicle (1) is moved to the location to be explored and then fixed. When geological samples are collected as needed, the support frame (2) is pulled by the telescopic hydraulic cylinder (21) so that the support frame (2) remains perpendicular to the ground to be sampled. At the same time, the support hydraulic cylinder (31) on the bracket (3) pushes the support foot (32) to contact the ground. The support foot (32) automatically adjusts the angle to keep it in contact with the ground, so that the fixing nail (33) is pressed into the ground to keep the support frame (2) stable. S2: Start the lifting motor (41) on the support frame (2). The lifting motor (41) drives the lead screw (4) to rotate, so that the slide plate (42) slides down on the support frame (2). At the same time, the drilling motor (5) starts, drives the drive gear (55) to rotate. The rotation of the drive gear (55) drives the transmission gear (56) meshed with it to rotate. After the transmission gear (56) drives the outer drill rod (51) to rotate, the outer drill bit (52) and inner drill bit (54) below the outer drill rod (51) rotate to drill holes in the ground. At the same time, the soil in the center of the hole can enter the center of the collection housing (61) through the center hole of the inner drill bit (54), and enter the circular tube surrounded by the conveying plate (81) through the center of the collection housing (61). As the outer drill rod (51) descends, the soil inside rises. S3: After reaching the set depth, the acquisition motor (65) on the acquisition housing (61) is started. The acquisition motor (65) drives the deflection gear (66) to rotate. The deflection gear (66) drives the drive ring (62) to rotate, which can drive the separation plate (63) to deflect relative to each other. At the same time, after the moving electromagnet (58) is energized, it attracts the moving gear (57), so that the moving gear (57) can mesh with another drive gear (55). The rotation of the drive gear (55) can drive the rotation of the inner drill rod (53). The inner drill rod (53) drives the acquisition housing (61) to deflect through the conveyor housing (7) that is slidably inserted with it, and drives the separation drill bit (64) to cut and separate the sample collected at the center of the acquisition housing (61). With the deflection of the separation plate (63), the samples above and below the separation plate (63) can be separated. S4: After separation, the moving electromagnet (58) is de-energized, and the connecting spring (59) resets the moving gear (57). The inner drill rod (53) stops rotating. The conveying motor (71) on the conveyor housing (7) starts and drives the conveying gear (72) to rotate. The conveying gear (72) rotates on the conveying rack (73) and drives the conveyor housing (7) to rise. The conveyor housing (7) rises on the guide rail (6). The soil collected above the separation plate (63) by the conveyor housing (7) rises and leaves the inner drill rod (53). After the adsorption electromagnet (8) is energized, the reset spring (82) is compressed. The adsorption electromagnet (8) adsorbs the conveying plate (81). The sample between the conveying plates (81) can be collected manually by the collection box.
