Description

Technical Field

[0001] The utility model relates to the technical field of exploration engineering drilling equipment, in particular to a drilling device for exploration. Background Art

[0002] Drilling equipment refers to mechanical devices and equipment used in specific drilling operations, primarily consisting of drilling rigs, mud pumps and mud purification equipment, mud mixers, and drilling towers. Drilling equipment is often used for sampling during land resource exploration.

[0003] However, the drilling equipment currently on the market for land resource exploration and sampling is not only complex in structure but also single in function. Its shock absorption effect is poor and internal components are easily damaged due to vibration during movement, which reduces the service life of the drilling equipment. In addition, the drill bit position of the existing drilling equipment is fixed and cannot be adjusted. When fine-tuning the drilling position is required, the entire drilling equipment must be moved, which is less practical.

[0004] For example, a drilling device for land resource exploration and sampling disclosed in Chinese patent publication number CN211851658U can reduce the vibration generated during the movement of the drilling device through the provided shock-absorbing spring, thereby achieving a certain shock-absorbing purpose and extending the service life of the drilling device. The provided sliding component can realize the left and right sliding of the drill rod, and the position of the drill bit can be adjusted to provide convenience for the drilling operation. During use, the telescopic cylinder is started to drive the piston rod to drive the second slider to slide left and right along the second slide groove, and then drive the third slider to slide left and right through the fixed block, thereby driving the drill bit to slide left and right through the drill rod, and the provided drive motor works to drive the screw to rotate, thereby causing the first slider to drive the crossbeam to slide up and down along the screw, thereby driving the drill bit to slide up and down through the drill rod, thereby achieving the purpose of drilling.

[0005] First, the above-mentioned device uses screws symmetrically arranged at both ends of the drill bit and the drill rod to connect the drive motor to complete the height lifting of the drill rod. On this basis, the sliding of the slider in the slide groove further completes the horizontal movement of the drill rod. However, in the above-mentioned device, the drill rod and the drill bit rub against the soil and rock formations for too long during long-term drilling work, so the temperature of the drill rod and the drill bit rises sharply. In addition, the motor is directly connected to the other end of the drill rod, which can easily cause the motor to overheat and melt. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention provides a drilling device for exploration, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a drilling device for exploration, comprising a mobile mounting base, a sealed shell for protection and sealing is provided on the top of the mobile mounting base, a sealed mounting frame is provided inside the sealed shell and is located directly above the mobile mounting base, and a drilling module for exploration is installed on the mounting frame;

[0008] The drilling module includes a driving motor installed on the top of the mounting frame and the output end of which is connected to the drill rod through a coupling. A drill bit is fixedly connected to the bottom of the drill rod. A spiral portion is provided between the drill rod and the drill bit. The upper and lower sliding sleeves of the drill rod are respectively provided with an upper cooling jacket and a lower cooling jacket.

[0009] In this embodiment, the driving motor drives the drill rod and the drill bit thereon to complete the drilling operation. The spiral portion provided can further improve the drilling effect. During the long drilling process, due to the long-term friction between the drill bit and the drill rod and the soil layer, the heat is transferred to the upper middle area of ​​the drill rod. In order to avoid heat conduction with the upper end driving motor, after the lower cooling jacket initially completes the cooling of the drill rod body, the upper cooling jacket is cooled again to ensure the cooling effect and avoid high-temperature short circuit of the directly connected driving motor.

[0010] A further improvement of the technical solution of the present invention is that a transmission plate located outside the drill pipe is provided on the outside of the upper cooling jacket, and the transmission plate is connected to the condensation box through water supply hoses inserted therein and symmetrically arranged at both ends, and the condensation box is installed on the side of the movable mounting seat.

[0011] A further improvement of the technical solution of the present invention is that: a plurality of transmission tubes 1 are arranged in a circle array on the transmission disk, the other end of the transmission tube 1 is connected to the upper cooling jacket through the upper cooling jacket and the seal thereon, and the upper cooling jacket and the lower cooling jacket are connected by a transmission tube 2; further, the coolant is transmitted to the upper cooling jacket through the transmission disk serving as a transfer, and the water supply hose and transmission tube 1 connected thereto, and the coolant circulates between the upper cooling jacket and the lower cooling jacket through the transmission tube 2, and both the upper cooling jacket and the lower cooling jacket need to be rotatably connected to the drill pipe; the seal provided therein is to prevent the coolant from overflowing.

[0012] A further improvement of the technical solution of the present utility model is that: a temperature detection component is slidingly provided on the drill rod and is limitedly installed on the mounting frame. The temperature detection component is close to the drill rod. The temperature detection component is connected to the water hose and the electric control valve is arranged on it. In order to ensure that overheating of the rod body can be detected in time and to avoid human contact to perceive the temperature, a temperature detection component is provided that is close to the rod body to complete the temperature detection work, and after the temperature is overheated, the conduction component and the sensor component inside it send an electrical signal to the electric control valve to complete the transmission of the cooling liquid; further, because the temperature detection component and the upper and lower cooling sleeves all need to ensure detection sensitivity and conduction sensitivity, they are all close to the rod body of the drill rod. On this basis, the surfaces of the temperature detection component and the upper and lower cooling sleeves that contact the rod body are smooth.

[0013] A further improvement of the technical solution of the present invention is that in order to avoid deviation of the mounting frame during lifting and lowering in the sealed shell and to further ensure the guiding performance of the lifting, a hydraulic rod for connection is provided between the mounting frame and the sealed shell, and the bottom of the mounting frame is symmetrically slidably connected to a guide block, the other end of which is welded to the top of the movable mounting seat.

[0014] A further improvement of the technical solution of the present utility model is that universal wheels for movement are symmetrically arranged at the bottom of the mobile mounting seat, and a pressure rod with a bottom fixedly connected to a limiting pressure pad is provided on the mobile mounting seat, and a limiting rod is provided on one side of the pressure rod which is limitedly inserted into the mobile mounting seat.

[0015] Beneficial effects

[0016] The utility model provides a drilling device for exploration. Compared with the prior art, it has the following beneficial effects:

[0017] 1. The drilling device used for exploration uses the lower cooling jacket in the drilling module to initially cool the drill pipe body, and then the upper cooling jacket performs cooling again to ensure the cooling effect. It uses heat conduction to avoid overheating of the drill pipe body, thereby avoiding high-temperature short circuit of the directly connected drive motor, further ensuring long-term normal drilling operation.

[0018] 2. The drilling device used for exploration ensures that it can detect overheating of the rod body in a timely manner through the temperature detection component, and avoids human contact to sense the temperature. The temperature detection component attached to the rod body completes the temperature detection work, and when the temperature is overheated, the conduction component and the sensor component inside it send an electrical signal to the electric control valve to complete the transmission of the coolant to complete the autonomous cooling.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figures 1-4 , this utility model provides three technical solutions:

[0030] Example 1:

[0031] A drilling device for exploration includes a mobile mounting base 1, a sealed housing 101 for protection and sealing is provided on the top of the mobile mounting base 1, a mounting frame 102 is provided inside the sealed housing 101 and is located directly above the mobile mounting base 1 and is sealed, and a drilling module for exploration is installed on the mounting frame 102;

[0032] The drilling module includes a driving motor 102-1 installed on the top of the mounting frame 102 and the output end of which is connected to the drill rod 102-2 through a coupling. A drill bit 102-3 is fixedly connected to the bottom of the drill rod 102-2. A spiral portion 102-4 is provided between the drill rod 102-2 and the drill bit 102-3. The upper and lower parts of the drill rod 102-2 are respectively provided with an upper cooling sleeve 102-5 and a lower cooling sleeve 102-6.

[0033] In this embodiment, the driving motor 102-1 drives the drill rod 102-2 and the drill bit 102-3 thereon to complete the drilling operation. The provided spiral portion 102-4 can further improve the drilling effect. In addition, during the long drilling process, due to the long-term friction between the drill bit 102-3 and the drill rod 102-2 and the soil layer, the heat is transferred to the upper middle area of ​​the drill rod 102-2. In order to avoid heat conduction with the upper end driving motor 102-1, after the lower cooling jacket 102-6 initially completes the cooling of the drill rod 102-2 rod body, the upper cooling jacket 102-5 is cooled again to ensure the cooling effect and avoid high temperature short circuit of the directly connected driving motor 102-1.

[0034] Example 2:

[0035] Based on Example 1:

[0036] A transmission plate 102-5a is provided outside the upper cooling jacket 102-5 and is located outside the drill rod 102-2. The transmission plate 102-5a is connected to the condensation box 102-5c through water supply hoses 102-5b symmetrically arranged at both ends and inserted therein. The condensation box 102-5c is installed on the side of the movable mounting base 1.

[0037] Several transmission tubes 102-5a-1 are arranged in a circular array on the transmission disk 102-5a. The other end of the transmission tube 102-5a-1 is connected to the upper cooling jacket 102-5 through the upper sealing member 102-5a-2. The upper cooling jacket 102-5 and the lower cooling jacket 102-6 are connected by the transmission tube 2 102-5a-3.

[0038] In this embodiment, based on the cooling solution provided in the first embodiment, the coolant is further transferred to the upper cooling jacket 102-5 through the transfer plate 102-5a, the water hose 102-5b connected thereto, and the first transfer pipe 102-5a-1. The coolant flows between the upper cooling jacket 102-5 and the lower cooling jacket 102-6 through the second transfer pipe 102-5a-3. Both the upper cooling jacket 102-5 and the lower cooling jacket 102-6 need to be rotatably connected to the drill pipe 102-2.

[0039] The sealing member 102-5a-2 is provided to prevent the coolant from overflowing.

[0040] A temperature detection assembly 102-2a is slidingly provided on the drill rod 102-2 and is limitedly mounted on the mounting frame 102. The temperature detection assembly 102-2a is close to the drill rod 102-2 and is connected to the water hose 102-5b and the electric control valve 102-2b is provided thereon.

[0041] In this embodiment, based on the first and second embodiments, in order to ensure that overheating of the rod body can be detected in a timely manner and to avoid human contact to sense the temperature, a temperature detection component 102-2a is provided in close contact with the rod body to complete the temperature detection work. When the temperature is overheated, the conductive component and the sensor component therein send an electrical signal to the electronically controlled valve 102-2b to complete the transmission of the coolant.

[0042] Furthermore, since the temperature detection component 102-2a and the upper and lower cooling sleeves need to ensure detection sensitivity and conduction sensitivity, they are all tightly attached to the rod body of the drill rod 102-2. On this basis, the surfaces of the temperature detection component 102-2a and the upper and lower cooling sleeves in contact with the rod body are all smooth.

[0043] Example 3:

[0044] On the basis of Example 1 and Example 2: In order to avoid the displacement of the installation frame 102 during the lifting and lowering in the sealed shell 101 and to further ensure the guidance of the lifting, a hydraulic rod 103 for connection is provided between the installation frame 102 and the sealed shell 101, and the bottom of the installation frame 102 is symmetrically slidably connected to a guide block 104, the other end of which is welded to the top of the movable mounting base 1.

[0045] The bottom of the mobile mounting base 1 is symmetrically provided with universal wheels 105 for movement, and the mobile mounting base 1 is provided with a pressure rod 107 with a fixed connection to a limiting pressure pad 106 at the bottom. One side of the pressure rod 107 is provided with a limiting rod 108 that is inserted into the mobile mounting base 1. During the drilling process, to prevent the entire drilling device from moving, the pressure rod 107 is pressed down, and its pressure pad 106 is raised as a support leg. At this time, the limiting rod 108 is inserted into the pressure rod 107 and the mobile mounting base 1 to limit the insertion.
