Description

Technical Field

[0001] This utility model relates to the field of tunnel drilling, and in particular to a drilling device with high stability. Background Technology

[0002] Currently, drilling equipment is mostly driven by electric motors, diesel engines, etc., which drive the drill bit to rotate and cut the rock through the drill pipe, or use impactors to generate impact force to break the rock. The mud pump delivers mud through the drill pipe to the bottom of the hole, which cools the drill bit, carries the rock cuttings, and stabilizes the hole wall. The rock cuttings are circulated with the mud to the surface, completing the drilling and obtaining geological samples.

[0003] Traditional drilling equipment is relatively bulky, and some pieces have complex structures with numerous parts, requiring high levels of maintenance and resulting in high costs. Furthermore, some drilling equipment has low levels of automation, relying heavily on manual operation, which is labor-intensive and demands high levels of skill and experience from operators. In addition, the high purchase cost of the equipment, its high energy consumption during operation, coupled with maintenance and labor costs, contribute to the persistently high overall cost of drilling projects.

[0004] In existing technology, for example, a high-stability drilling device with heat dissipation function, as disclosed in CN110552624A, includes a vehicle body, a drive unit, and a drill rod. The stabilization mechanism includes a support plate and two stabilization components. Each stabilization component includes a fixed box, moving wheels, a first connecting rod, a first moving plate, a second moving plate, a drive unit, two telescopic units, and two stabilization units. Each stabilization unit includes a second connecting rod, a fixed plate, and several saw teeth. The heat dissipation mechanism includes a rotating plate, two heat dissipation components, and a moving component. Each heat dissipation component includes a connecting box, a filter screen, a fan, and a cooling rod. This high-stability drilling device with heat dissipation function effectively cools the drill rod during drilling operations, preventing overheating and ensuring normal operation. The stabilization mechanism also secures the drill rod, preventing slippage and ensuring drilling accuracy and effectiveness. However, this design has certain drawbacks: the sampling tube is not replaceable, making it unsuitable for different drilling needs, and there is no storage device for the sampled material, hindering subsequent retrieval and analysis.

[0005] Therefore, this application provides a drilling device with high stability to solve the problems mentioned in the background art. Utility Model Content

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A highly stable drilling device includes a vehicle body, a drawer slidably disposed on the inner wall of the vehicle body, several partitions fixedly disposed inside the drawer, protective pads fixedly disposed on both sides of the partitions, a drive wheel and a driven wheel rotatably disposed on both sides of the vehicle body, tracks disposed on the outer sides of the drive wheel and the driven wheel, a lifting mechanism disposed at the front end of the vehicle body, a support plate fixedly disposed at the front end of the lifting mechanism, a motor fixedly disposed at the upper end of the support plate, a connecting plate fixedly disposed at the output end of the motor, and a drilling mechanism fixedly disposed at the lower end of the connecting plate.

[0009] Furthermore, multiple cylinders are fixedly installed on both the front and rear ends of the vehicle body, and connecting rods are fixedly installed at the output ends of the multiple cylinders, with rubber bases fixedly installed at the lower ends of the multiple connecting rods.

[0010] Furthermore, a control panel is fixedly installed on one side of the vehicle body.

[0011] Furthermore, the drilling mechanism includes an extension rod, the lower end of which is threaded with a sampling rod, and the lower end of which is fixedly fitted with a drill bit.

[0012] Furthermore, the upper and lower mechanism includes a forward and reverse rotating motor, a base frame is fixedly installed at the lower end of the forward and reverse rotating motor, guide rails are fixedly installed on both sides of the upper end of the base frame, and an upper limit plate is fixedly connected to the upper end of the guide rails.

[0013] Furthermore, a lead screw is fixedly installed at the output end of the forward and reverse motor, and a slider is threaded on the outer surface of the lead screw.

[0014] Furthermore, a lower limit plate is fixedly connected to the lower end of the guide rail.

[0015] This utility model has the following beneficial effects:

[0016] 1. The present invention proposes a highly stable drilling device that uses replaceable sampling tubes to flexibly adapt to different drilling needs. Facing drilling tasks with different geological conditions and depths, the sampling tubes of appropriate specifications can be replaced at any time to improve work efficiency. At the same time, it reduces maintenance costs. When the sampling tubes are worn or damaged, only the local parts need to be replaced, avoiding the replacement of the entire equipment. It is also easy to clean and disinfect, prevents cross-contamination of samples, and ensures sampling accuracy. For corrosive or contaminating samples, the sampling tubes can be replaced in time to reduce damage to the equipment.

[0017] 2. This utility model proposes a highly stable drilling equipment with a sampling material storage device. This effectively avoids the haphazard stacking of samples at the drilling site, preventing sample confusion, contamination, or damage, and ensuring the originality and accuracy of the samples. The device, through partitioned and categorized storage, can quickly identify samples of different depths and types, facilitating subsequent retrieval and analysis. Simultaneously, the enclosed or protective storage device can resist interference from external environmental factors such as rain and dust erosion, and stably protects the samples during transportation, providing reliable sample support for geological research, resource exploration, and other work.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 One embodiment provided by this utility model:

[0026] A high-stability drilling device includes a vehicle body 1. A drawer 2 is slidably arranged on the inner wall of the vehicle body 1. Several partitions 4 are fixedly arranged inside the drawer 2. Protective pads 3 are fixedly arranged on both sides of the partitions 4. A drive wheel 5 and a driven wheel 7 are rotatably arranged on both sides of the vehicle body 1. Tracks 6 are arranged on the outer sides of the drive wheel 5 and the driven wheel 7. A lifting mechanism 15 is arranged at the front end of the vehicle body 1. A support plate 13 is fixedly arranged at the front end of the lifting mechanism 15. A motor 14 is fixedly arranged at the upper end of the support plate 13. A connecting plate 12 is fixedly arranged at the output end of the motor 14. A drilling mechanism 11 is fixedly arranged at the lower end of the connecting plate 12. Multiple cylinders 10 are fixedly arranged on both the front and rear ends of the vehicle body 1. Connecting rods 9 are fixedly arranged at the output ends of the multiple cylinders 10. Rubber bases 8 are fixedly arranged at the lower ends of the multiple connecting rods 9. A control panel 16 is fixedly arranged on one side of the vehicle body 1.

[0027] Specifically, drawers 2 are slidably installed on the inner wall of the vehicle body 1. Each drawer 2 contains a temperature and humidity control device to ensure samples are stored in a suitable environment. The outer side of each drawer 2 has a recessed handle and a keyhole for locking it. Protective pads 3, made of soft material, are placed in the spaces of each drawer 2 separated by partitions 4 to hold sampling materials and prevent damage from vibrations during vehicle body 1 movement. Two SC50×100 cylinders 10 are installed on each of the front and rear ends of the vehicle body 1, with a stroke of 100mm and a maximum thrust of 196N. The drive wheel 5 is controlled by a motor, which in turn controls the movement of the track 6 and the driven wheel 7. The track 6 uses a hydraulic tensioning device to adjust the tension, which has the advantages of large tension, good stability, and less susceptibility to vibration. Multiple connecting rods 9 work with the rubber base 8 to fix the equipment. The rubber base 8 is easy to deform and has high friction, which makes the equipment stable on the ground in different environments, reduces vibration, and extends the service life of the track 6. The up and down mechanism 15 controls the up and down of the support plate 13 and the motor 14. The motor 14 controls the connection plate 12 and the drilling mechanism 11. The control panel 16 is equipped with a main power switch, a cylinder 10 control button group, a motor 14 start / stop knob, track 6 forward and backward control keys, and up and down mechanism 15 lifting adjustment buttons. The layout of each control component is reasonable and the operation labels are clear.

[0028] refer to Figure 3 The drilling mechanism 11 includes an extension rod 1101, a sampling rod 1102 is threaded at the lower end of the extension rod 1101, and a drill bit 1103 is fixedly installed at the lower end of the sampling rod 1102.

[0029] Specifically, the extension rod 1101 can extend the depth of the sampling rod 1102, making it easier to sample soil at deeper depths. The extension rod 1101 and the sampling rod 1102 are threaded together, and the sampling rod 1102 can be removed and replaced at any time.

[0030] refer to Figure 4The upper and lower mechanism 15 includes a forward and reverse motor 1506. A base frame 1507 is fixedly installed at the lower end of the forward and reverse motor 1506. Guide rails 1504 are fixedly installed on both sides of the upper end of the base frame 1507. An upper limit plate 1501 is fixedly connected to the upper end of the guide rails 1504. A lead screw 1503 is fixedly installed at the output end of the forward and reverse motor 1506. A slider 1502 is threaded on the outer surface of the lead screw 1503. A lower limit plate 1505 is fixedly connected to the lower end of the guide rails 1504.

[0031] Specifically, the slider 1502 is fixed on the guide rail 1504 to facilitate stable movement of the slider 1502. A lower limit plate 1505 and an upper limit plate 1501 are fixedly placed at both ends of the guide rail 1504 to limit the range of motion of the slider 1502. The forward and reverse motor 1506 controls the rotation direction of the lead screw 1503 by rotating forward and backward, thereby controlling the up and down movement of the slider 1502 and causing the support plate 13 to move up and down as well. The base frame 1507 has a square outer frame, which not only shields the drilling mechanism 11 from the soil and debris splashed during operation but also prevents workers from approaching.

[0032] Working principle: The vehicle body 1 is moved to the designated position using the control panel 16. First, the cylinder 10 controls the connecting rod 9 downwards, so that the connecting rod 9 and the rubber base 8 contact the ground, lifting the vehicle body 1 and fixing it to the ground. Then, the motor 14 is started, causing the drilling mechanism 11 to rotate. Then, the forward and reverse motor 1506 is controlled to rotate the lead screw 1503, causing the slider 1502 to move downwards along the guide rail 1504. The drilling mechanism 11 moves downwards to collect samples. When the drilling mechanism 11 reaches the preset drilling depth, the sampling is considered complete. After sampling is complete, the forward and reverse motor 1506 is controlled to move the drilling mechanism 11 upwards. Then, the sampling rod 1102 is unscrewed by the thread to remove the sample and place it in the drawer 2.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
