[0001] This utility model belongs to the field of geological drilling technology, specifically relating to a drilling device suitable for fractured strata. Background Technology
[0002] Currently, in geological drilling, drilling equipment is generally used to drill into the ground at different depths to facilitate the sampling of underground soil at different depths. This allows for a deeper understanding of the geology of strata at different depths and enables efficient drilling of different geological conditions.
[0003] Existing drilling equipment generates a large amount of dust and violent vibrations during the drilling process. The violent vibrations make it difficult for workers to operate the equipment and require a lot of physical exertion. The dust flying during the drilling process can be inhaled by workers, which is harmful to their health. Utility Model Content
[0004] To address the problems mentioned in the background art, this utility model provides a drilling device suitable for fractured strata, which solves the problems of generating a large amount of dust and violent vibration during drilling, making it difficult for workers to operate the device and requiring a lot of physical exertion, and the fact that the dust flying during drilling can be inhaled by workers, endangering their health.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device suitable for fractured strata, comprising a workbench, an installation frame fixedly mounted on one side of the workbench surface, a first motor mounted on one side of the top of the installation frame, an output end of the first motor connected to a threaded rotating shaft, a movable block threadedly connected to the surface of the threaded rotating shaft, a connecting plate fixedly connected to one side of the surface of the movable block, and one side of the surface of the connecting plate fitting against one side of the surface of the installation frame, a second motor mounted on one side of the top of the connecting plate, an outer core cylinder connected to the output end of the second motor, a core drill bit connected to one end of the outer core cylinder, an installation ring sleeved inside the outer core cylinder, a core claw fixedly connected to the bottom of the installation ring, and an inner core cylinder connected to one side of the bottom of the connecting plate.
[0006] Preferably, a dust collection box is provided on one side of the workbench surface, a vacuum cleaner is installed on one side of the surface of the dust collection box, and a vacuum suction pipe is connected to one side of the interior of the dust collection box.
[0007] Preferably, a dust suction head is connected inside the center of the workbench, and the position of the dust suction head corresponds to that of the core drill bit. One side of the inside of the dust suction head is connected to a dust suction pipe.
[0008] Preferably, a handle is fixedly installed at one end of the workbench surface.
[0009] Preferably, the mounting frame has a limiting groove inside, and the surface of the limiting groove is slidably connected to the surface of the movable block.
[0010] Preferably, each of the four corners of the bottom of the workbench is fixedly connected with an L-shaped connecting block, and a placement plate is installed on one side of the surface of the L-shaped connecting block. There are two sets of placement plates, and the positions of the two sets of placement plates correspond to each other.
[0011] Preferably, an elastic telescopic rod is connected to one side of the bottom of the L-shaped connecting block, a return spring is sleeved on one side of the surface of the elastic telescopic rod, a support block is connected to one side of the bottom of the elastic telescopic rod, and a caster wheel is installed at one end of the support block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] Through the cooperation of the limiting groove, return spring, and elastic telescopic rod, the limiting groove restricts the position of the moving block, making the core drill bit more stable during drilling and reducing the vibration generated during drilling. The severe vibration generated during drilling will cause the elastic telescopic rod to contract. When the elastic telescopic rod contracts to the critical point, the return spring will release the elastic telescopic rod, thereby absorbing most of the impact force generated during the vibration, making it easier for the staff to operate and reducing the physical exertion of the staff. Through the cooperation of the vacuum cleaner, vacuum pipe, vacuum head, and vacuum box, during the core drilling and core extraction process, the vacuum cleaner will drive the vacuum pipe and vacuum head to suck the dust generated during drilling into the vacuum box, preventing the dust from being dispersed into the air and inhaled by the staff, thus protecting the health of the staff.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-8 The present invention provides the following technical solution: a drilling device suitable for fractured strata, comprising a workbench 1, an installation frame 3 fixedly installed on one side of the surface of the workbench 1, a first motor 12 installed on one side of the top of the installation frame 3, a threaded rotating shaft 18 connected to the output end of the first motor 12, a movable block 17 threadedly connected to the surface of the threaded rotating shaft 18, a connecting plate 4 fixedly connected to one side of the surface of the movable block 17, and one side of the surface of the connecting plate 4 fitting against one side of the surface of the installation frame 3, a second motor 14 installed on one side of the top of the connecting plate 4, an outer core cylinder 15 connected to the output end of the second motor 14, a core drill bit 16 connected to one end of the outer core cylinder 15, an installation ring 19 sleeved inside the outer core cylinder 15, a core claw 20 fixedly connected to the bottom of the installation ring 19, and an inner core cylinder 21 connected to one side of the bottom of the connecting plate 4.
[0026] In this embodiment, the inner core tube 21, the outer core tube 15, and the core claw 20 form an independent core sampling channel, which better protects the integrity of the core and improves the core recovery rate in fractured strata.
[0027] In this embodiment, the vacuum cleaner 23 drives the vacuum pipe 22 and the vacuum head 24 to work, thereby sucking the dust scattered during the drilling process into the vacuum box 5, preventing the dust from being inhaled by the workers in the air and better protecting the health of the workers.
[0028] In this embodiment, the limiting groove 13 restricts the position of the movable block 17, so that the movable block 17 can only move vertically up and down, ensuring that the core drill bit 16 always remains vertical during the drilling process, reducing the risk of borehole wall collapse.
[0029] In this embodiment, the two sets of corresponding installation plates 6 can be used to temporarily place tools, making it convenient for staff to operate.
[0030] In this embodiment, the handle 2 and the caster 8 work together. The handle 2 is more ergonomically designed, making it easier for workers to push the device. The caster 8 allows workers to easily control the device to move quickly to the corresponding drilling position.
[0031] The working principle and usage process of this utility model are as follows: After the utility model is installed, the device is moved to the corresponding drilling position using handle 2. The vacuum cleaner 23 is started, causing the vacuum pipe 22 and vacuum head 24 to work. Then, the second motor 14 is started, causing the outer core cylinder 15 to rotate, thereby causing the core drill bit 16 and core claw 20 to rotate. The first motor 12 is started, causing the threaded rotating shaft 18 to rotate, thereby causing the movable block 17 to descend under the restriction of the limiting groove 13, which in turn causes the connecting plate 4, outer core cylinder 15, and inner core cylinder 21 to descend. Through the continuous rotation and descent of the core drill bit 16, the formation is drilled. The dust generated during the drilling process is sucked into the dust collection box 5 by the vacuum head 24 and the vacuum pipe 22. The violent vibration generated during the drilling process will cause the elastic telescopic rod 10 and the return spring 9 to retract, thereby... The entire device is lowered. When the return spring 9 contracts to the critical point, it releases the elastic telescopic rod 10, thereby resetting the entire device and reducing the impact force generated by vibration. During the drilling process of the core drill bit 16, outer core cylinder 15, and inner core cylinder 21, the core will enter the interior of the inner core cylinder 21. When the corresponding position is reached, the threaded rotating shaft 18 drives the movable block 17 to rise, thereby driving the outer core cylinder 15 and inner core cylinder 21 to rise. During the rising process, the core claw 20 will separate the core inside the inner core cylinder 21 from the strata. After the movable block 19 is raised to the corresponding position, the second motor 14 and the first motor 12 are turned off, and then the collected core can be taken out. All electrical equipment in this device is powered by an external power supply, and all motors or electric push rods in this paper are controlled by a PLC control system.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
