Description

Technical Field

[0001] This invention belongs to the field of geological exploration technology, and more specifically, relates to a vehicle-mounted drilling rig for coal geological exploration. Background Technology

[0002] In the field of coal geological exploration, it is often necessary to study deep soil layers. As a core piece of equipment, truck-mounted drilling rigs play a crucial role in obtaining information about underground coal resources.

[0003] Current truck-mounted drilling rigs still have the following shortcomings:

[0004] The sampling process is complex and cumbersome. Existing drilling rigs lack efficient sampling structures. When it is necessary to collect coal samples at different depths, it is often necessary to raise the drill multiple times and use different tools. This not only consumes a lot of time and manpower, but also easily leads to sample contamination, affecting the accuracy of the test results. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a vehicle-mounted drilling rig for coal geological exploration. This addresses the issue raised in the background section where existing drilling rigs lack efficient sampling structures. When collecting coal samples at different depths, it is often necessary to repeatedly lift the drill and use different tools, which not only consumes a lot of time and manpower but also easily leads to sample contamination, affecting the accuracy of the test results.

[0006] The purpose and effectiveness of this invention, a vehicle-mounted drilling rig for coal geological exploration, are achieved through the following specific technical means:

[0007] A vehicle-mounted drilling rig for coal geological exploration includes: a self-propelled base and a drill rod; the self-propelled base adopts a rectangular seat structure, and a wheel structure is rotatably arranged around the perimeter of the self-propelled base; the drill rod adopts an internally hollow cylindrical structure, and a through-type arc-shaped groove structure is opened on one side of the bottom of the drill rod, and a through-type circular groove structure is opened on the inner side of the bottom of the drill rod; a cylindrical slide rod is slidably arranged in the circular groove at the bottom of the drill rod; an arc-shaped scraper is fixedly connected to one side of the slide rod, and the size of the scraper matches the size of the arc-shaped groove on one side of the bottom of the drill rod; a rack is fixedly connected to the inner end of the scraper.

[0008] Furthermore, an L-shaped block structure mounting seat is fixedly provided on the top of the self-propelled base; a set of cylinders is rotatably connected to both sides of the mounting seat.

[0009] Furthermore, a rectangular block structure connecting block is rotatably connected to the front side of the mounting base; a rectangular frame structure fixing frame is fixedly installed on the front side of the connecting block, and a guide rail structure is provided on the front side of the fixing frame; a rectangular block structure fixing block is fixedly installed in the middle of the rear side of the fixing frame, and the two sides of the fixing block are rotatably connected to two sets of cylinders respectively; a winding machine is fixedly installed on one side of the fixing block; and rollers are rotatably installed on the top of the fixing frame.

[0010] Furthermore, a U-shaped sliding block is slidably provided on the front side of the fixed frame, and the sliding block is connected to the winding machine through a steel wire rope that passes around the roller. A drill rod is rotatably provided at the bottom of the sliding block; a second motor is fixedly provided at the bottom of the sliding block, and the second motor is connected to the drill rod through a gear set.

[0011] Furthermore, a drill bit is fixedly connected to the bottom end of the drill rod; a cylindrical transmission rod is rotatably mounted on the inner side of the drill rod; a first motor is fixedly mounted at the top end of the drill rod, and the first motor is connected to the transmission rod in a transmission connection; a gear is fixedly mounted at the bottom of the transmission rod, and the gear is meshed with a rack.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes a unique automatic sampling structure. After drilling to a preset depth, simply activating the first motor allows the scraper to extend and conform to the borehole wall. The second motor then rotates the drill rod to complete the scraping and sampling, avoiding the tedious operation of repeatedly lifting the drill and changing tools, thus significantly improving sampling efficiency. Simultaneously, after sampling, the scraper can seal the arc-shaped groove of the drill rod, effectively preventing soil from different depths from mixing in, ensuring sample purity, and significantly improving the accuracy of subsequent testing.

[0014] The combination of the self-propelled base and the adjustable drill frame allows the drilling rig to be easily moved to different working positions. The angle of the fixed frame and the drill bit can be flexibly adjusted by the cylinder. Whether it is vertical drilling or inclined drilling, whether it is flat ground or complex terrain environment, it can easily cope with the needs, greatly expanding the applicable scenarios of the equipment.

[0015] The drill pipe lifting system, consisting of a winder, wire rope, and rollers, utilizes rollers to change the direction of force on the wire rope and reduce friction, ensuring a smooth and stable lifting process. Combined with the guide rails of the fixed frame for precise guidance of the sliding blocks, this effectively improves stability and accuracy during drilling, reduces the risk of equipment failure, and ensures efficient and reliable coal geological exploration.

[0023] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown:

[0025] This invention provides a vehicle-mounted drilling rig for coal geological exploration, comprising: a self-propelled base 1 and a drill rod 109; the self-propelled base 1 adopts a rectangular base structure, and a wheel structure is rotatably arranged around the perimeter of the self-propelled base 1; the drill rod 109 adopts an internally hollow cylindrical structure, and a through arc-shaped groove structure is opened on one side of the bottom of the drill rod 109, and a through circular groove structure is opened on the inner side of the bottom of the drill rod 109; a cylindrical slide rod 114 is slidably arranged in the circular groove at the bottom of the drill rod 109; an arc-shaped scraper 115 is fixedly connected to one side of the slide rod 114, and the size of the scraper 115 matches the size of the arc-shaped groove on one side of the bottom of the drill rod 109; a rack 116 is fixedly connected to the inner end of the scraper 115.

[0026] The fixed frame 104 has a U-shaped sliding block 108 slidably mounted on its front side. The sliding block 108 is connected to the winding machine 106 via a wire rope that passes over the roller 107. A drill rod 109 is rotatably mounted on the bottom of the sliding block 108. A second motor 117 is fixedly mounted on the bottom of the sliding block 108. The second motor 117 is connected to the drill rod 109 via a gear set to provide power for the rotation of the drill rod 109, enabling the drill bit 110 to cut and drill into the formation.

[0027] The drill rod 109 has a drill bit 110 fixedly connected to its bottom end; a cylindrical transmission rod 111 is rotatably mounted on the inner side of the drill rod 109; a first motor 112 is fixedly mounted at the top end of the drill rod 109 and is connected to the transmission rod 111; a gear 113 is fixedly mounted at the bottom of the transmission rod 111 and is meshed with a rack 116. When the first motor 112 is working, it drives the transmission rod 111 to rotate, which in turn causes the scraper 115 to extend or retract through the transmission of the gear 113 and the rack 116.

[0028] The specific usage and function of this embodiment are as follows:

[0029] After drilling to the preset depth, when sampling is required, the first motor 112 is started, which drives the transmission rod 111 to rotate. Through the meshing of the gear 113 and rack 116, the slide rod 114 drives the scraper 115 to extend radially along the arc-shaped through groove at the bottom of the drill rod 109 until the scraper 115 is in close contact with the borehole wall. Then, the second motor 117 is started again to drive the drill rod 109 to rotate slowly. The scraper 115 scrapes the surrounding coal, allowing some coal to enter the cavity at the bottom of the drill rod 109. After sampling is completed, the first motor 112 is rotated in the opposite direction to retract the scraper 115 to the outside of the drill rod 109, sealing the arc-shaped through groove of the drill rod 109. This prevents soil of different depths from entering the cavity of the drill rod 109 during the lifting process, which could contaminate the sample and affect the accuracy of subsequent testing. This provides better protection for the sample and meets the sampling needs at different depths, greatly improving the efficiency of coal geological exploration.

[0030] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown:

[0031] The self-propelled base 1 has an L-shaped block structure mounting seat 101 fixedly installed on its top; a set of cylinders 102 are rotatably connected to both sides of the mounting seat 101.

[0032] The mounting base 101 has a rectangular block connecting block 103 rotatably connected to its front side; a rectangular frame fixing frame 104 is fixedly installed on the front side of the connecting block 103, and a guide rail structure is provided on the front side of the fixing frame 104; a rectangular block fixing block 105 is fixedly installed in the middle of the rear side of the fixing frame 104, and the two sides of the fixing block 105 are rotatably connected to two sets of cylinders 102 respectively; a winding machine 106 is fixedly installed on one side of the fixing block 105; a roller 107 is rotatably installed on the top of the fixing frame 104. The winding machine 106 controls the feed of the drill rod 109 through a wire rope. The roller 107 changes the direction of force on the wire rope and reduces friction, ensuring that the drill rod 109 rises and falls smoothly.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In this invention, the position of the entire device is moved and adjusted by the self-propelled base 1. After being moved to the designated position, the two sets of cylinders 102 retract, driving the fixed frame 104 and the fixed block 105 to rotate around the front end of the mounting base 101, thereby adjusting the overall angle and the drilling angle of the drill bit 110 to meet different construction needs. After the adjustment is completed, the wire rope is wound and released by the winding machine 106, thereby driving the sliding block 108 to slide up and down along the fixed frame 104, thereby adjusting the feed depth of the drill rod 109 and the drill bit 110. The second motor 117 is started, which drives the drill rod 109 to rotate through the gear set, and the drill bit 110 begins to drill into the stratum.
