Abstract
Description
Technical Field
[0001] This application relates to the field of portable drilling equipment technology, and specifically discloses a portable drilling equipment for underground geological exploration. Background Technology
[0002] Mineral exploration engineering, sometimes also called exploration technology, generally refers to the engineering technology related to geological exploration work. At a predetermined location, drilling equipment is used to drill through rock strata to obtain physical data such as rock samples, water samples, and soil samples. The drilling is also used to conduct underground physical measurements or groundwater dynamic observations. It is the most widely used technology in geological exploration.
[0003] Since drilling depth can significantly affect drilling results, strict requirements are necessary. Currently, most portable drilling devices do not have strict requirements on drilling depth. These portable drilling devices often limit drilling depth using a ruler, which is installed on the drill rod to mark the depth. While the operation itself is not problematic, portable drilling devices are prone to tilting. Once the drilling is tilted, this method becomes inaccurate. Furthermore, due to the direction of force application and human error, existing portable drilling devices often cannot control whether the drill rod is driven vertically, which can lead to the aforementioned series of problems. In view of this, the inventor proposes a portable drilling device for underground geological exploration. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the drill rod in traditional portable drilling devices is not driven vertically, which leads to large errors in the scale reading.
[0005] To achieve the above objectives, this utility model provides the following basic solution:
[0006] A portable drilling device for underground geological exploration includes a telescopic component that contacts the ground and a connecting component that connects to the telescopic component.
[0007] Telescopic assembly: includes several support rods in contact with the ground, collars that slide up and down on the support rods, and a scale set on the support rods; the connecting assembly is fixedly connected to the collars.
[0008] Connection assembly: includes a mounting bracket, a connecting cylinder detachably connected to the mounting bracket, and a rotating assembly connected to the rotating cylinder. One end of the rotating assembly is connected to a drive assembly, and the other end of the rotating assembly is detachably connected to a drill rod for drilling.
[0009] The principle and effect of this basic scheme are as follows:
[0010] 1. Compared with the existing technology, this device has a simple structure and ingenious design. This device is equipped with a connecting component, which can be connected to a manual drive component or a mechanized drive component, thereby realizing manual or automated drilling. Through manual or automated drilling, this device can flexibly select the power form, thereby achieving reasonable drilling.
[0011] 2. Compared with the prior art, this device is equipped with a telescopic component, which is set together with the connecting component. When the telescopic component moves, it can drive the connecting component to move. The amount of movement of the telescopic component is the amount of movement of the connecting component, thus realizing the drilling volume. This solves the problem of large scale reading errors caused by the non-vertical driving of the drill rod in traditional portable drilling devices.
[0012] 3. Compared with the prior art, this device can avoid non-vertical drilling of the drill rod. This is because the telescopic component of this device is fixed, and the connecting component can only move up and down relative to the telescopic component, without any movement in other directions. Therefore, the connecting component will only be driven in vertically, thus ensuring the correct driving direction of this device.
[0013] Furthermore, each free end of the support rod is fixedly connected to a pin, all of which are inserted below the ground. The drill rod includes a drill rod body and a drill bit, with the drill bit in contact with the ground. This achieves stable support for the device.
[0014] Furthermore, it also includes a fixing nut. The collar has a number of sliding holes, each corresponding to a specific position on the support rod. The support rod has external threads, and the fixing nut is threadedly connected to the external threads. This allows the collar to move up and down under the action of the fixing nut.
[0015] Furthermore, connecting rods are fixedly connected to all four sides of the mounting frame, and the free ends of the connecting rods are fixedly connected to the inner wall of the collar. The inner wall of the mounting frame is provided with a mounting platform, and the inner wall of the mounting platform is provided with connecting threads, through which the connecting cylinder is connected. This achieves a detachable connection of the connecting cylinder.
[0016] Furthermore, the connecting cylinder includes a cylinder body and end caps disposed at both ends of the cylinder body, and the rotating assembly includes a rotating shaft and a first shaft connector and a second shaft connector disposed at both ends of the rotating shaft. The first shaft connector is connected to the driving assembly, and the second shaft connector is connected to the drill rod.
[0017] Furthermore, the drive component is a hand crank, which is coaxially connected to the first shaft connector.
[0018] Furthermore, the driving component is a motor, and the output shaft of the motor is coaxially connected to the first shaft connector.
[0019] Furthermore, the second shaft connector is an internally threaded connector, which connects to the drill rod.
[0020] Furthermore, the drill pipe is made of stainless steel, ensuring its service life and strength.
[0021] Furthermore, the stainless steel drill pipe is made of 304 stainless steel. This ensures the service life and strength of the drill pipe while maintaining a certain level of cost. Attached Figure Description
[0022] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0023] Figure 1 This paper shows a schematic diagram of the structure of a portable drilling device for downhole geological exploration according to an embodiment of this application;
[0024] Figure 2 This image shows a front view of a portable drilling device for downhole geological exploration according to an embodiment of this application. Detailed Implementation
[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0026] The reference numerals in the accompanying drawings include: collar 1, connecting rod 2, support rod 3, connecting cylinder 4, mounting platform 5, first shaft connector 6, scale 7, pin 8, drill rod 9, fixing nut 10, and external thread 11.
[0027] Implementation, for example Figure 1 and Figure 2 As shown:
[0028] A portable drilling device for underground geological exploration includes a telescopic component that contacts the ground and a connecting component that connects to the telescopic component.
[0029] Telescopic assembly: includes several support rods 3 in contact with the ground, a collar 1 that is fitted on the support rods 3 to allow them to slide up and down, and a scale 7 set on the support rods 3. The connecting assembly is fixedly connected to the collar 1.
[0030] Specifically: such as Figure 1As shown, each free end of the support rod 3 is fixedly connected to a pin 8, and all pins 8 are inserted below the ground. The drill rod 9 includes a drill rod body and a drill bit, with the drill bit in contact with the ground. This achieves stable support for the device.
[0031] The pin 8 needs to be fully inserted below the ground, and the scale 7 needs to be set on the support rod 3, reasonably avoiding the position of the external thread 11. Regarding the external thread 11:
[0032] It also includes a fixing nut 10. The collar 1 has a number of sliding holes, each corresponding to a different support rod 3 in terms of quantity and position. The support rod 3 has an external thread 11 on its exterior. The fixing nut 10 is threadedly connected to the external thread 11. This allows the collar 1 to move up and down under the action of the fixing nut 10.
[0033] Specifically:
[0034] Since this case uses the movement of the telescopic component to drive the movement of the connecting component, the collar 1 is used to achieve the height change of the connecting component at different heights, and the position of the collar 1 is fixed by the fixing nut 10. Thus, while achieving the height change of the connecting component, the position of the connecting component is also fixed.
[0035] Connection assembly: includes a mounting bracket, a connecting cylinder 4 detachably connected to the mounting bracket, and a rotating assembly connected to the rotating cylinder. One end of the rotating assembly is connected to a drive assembly, and the other end of the rotating assembly is detachably connected to a drill rod 9 for drilling.
[0036] On the connection:
[0037] The mounting bracket is fixedly connected to all four sides by connecting rods 2. The free ends of the connecting rods 2 are fixedly connected to the inner wall of the collar 1. The inner wall of the mounting bracket is provided with a mounting platform 5, and the inner wall of the mounting platform 5 is provided with connecting threads. The connecting cylinder 4 is connected through the connecting threads, thereby realizing the detachable connection of the connecting cylinder 4.
[0038] Regarding connecting cylinder 4:
[0039] The connecting cylinder 4 includes a cylinder body and end caps disposed at both ends of the cylinder body. The rotating assembly includes a rotating shaft and a first shaft connector 6 and a second shaft connector disposed at both ends of the rotating shaft. The first shaft connector 6 is connected to the drive assembly, and the second shaft connector is connected to the drill rod 9.
[0040] In the driver component:
[0041] The drive component is a motor, and the output shaft of the motor is coaxially connected to the first shaft connector 6.
[0042] The drive component is a hand crank, which is coaxially connected to the first shaft connector 6.
[0043] Specifically:
[0044] The device can be connected to a manual drive component or a mechanical drive component to enable manual or automated drilling. By using manual or automated drilling, the device can flexibly select the power source to achieve optimal drilling results.
[0045] Regarding the connection of drill pipe 9:
[0046] The second axis connector is an internally threaded connector, which connects to the drill rod 9. The drill rod 9 is made of stainless steel. This ensures the service life and strength of the drill rod 9; specifically, the stainless steel drill rod 9 is made of 304 stainless steel. This approach ensures the service life and strength of the drill rod 9 while maintaining a certain level of cost control.
[0047] Specific implementation process:
[0048] First, after all the pins 8 are on the ground, fix the device, select the drill bit and drill rod 9 body, and then determine the drilling depth;
[0049] The second step is to adjust the fixing nut 10 after the drilling depth is determined. The distance the fixing nut 10 moves downward is determined by the scale 7. The distance the fixing nut 10 moves downward is the distance the connecting component moves downward.
[0050] Third, the worker stabilizes the collar 1 and gradually moves it downwards, bringing the collar 1 close to the fixing nut 10. During this process, it is necessary to select whether the output power source is a motor or a hand crank, depending on the actual situation. Then, since the collar 1 contacts the fixing nut 10, drilling will stop. It is important to note in this case that before adjusting the fixing nut 10, after installing the drill rod 9, the head of the drill bit needs to contact the ground to ensure the accuracy of the drilling depth.
[0051] This device solves the problem of large errors in scale readings caused by the non-vertical driving of the drill rod 9 in traditional portable drilling devices.
[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
