Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically a drilling rig for coalfield geological exploration. Background Technology

[0002] Geological exploration uses methods such as surveying, geophysical exploration, geochemical prospecting, drilling, pitting, sampling and testing, and geological remote sensing to understand the geological conditions of the measured area, including rocks, stratigraphic structure, minerals, groundwater, and landforms. Drilling equipment, or drilling rigs, is needed to drill through the ground and sample and analyze soil or rock layers at different depths.

[0003] An engineering geological exploration drilling rig, such as one disclosed in announcement number CN222576602U, includes a housing with a drill rod positioned below it. A cooling mechanism is located inside the housing. The cooling mechanism includes a cooling coil fixedly embedded inside the drill rod. A liquid storage tank is fixedly connected to the inner wall of the housing, and an outlet pipe is fixedly connected to the left side of the storage tank. A sealing cover is fixedly connected to the outer surface of the outlet pipe, and a sealing bearing is fixedly connected to the inner wall of the sealing cover. A rotating disc is fixedly connected to the inner wall of the inner ring of the sealing bearing. A first small bearing and a second small bearing are respectively fitted onto the inlet and outlet ends of the cooling coil. This engineering geological exploration drilling rig allows for timely cooling of the drill rod, reducing thermal wear and increasing the service life of the drill rod. This enables the engineering geological exploration drilling rig to be used outdoors for extended periods without frequent drill rod replacements due to wear.

[0004] The aforementioned patent proposes that the drill rod can be cooled in time through a cooling mechanism to reduce thermal wear. However, during the use of the drilling rig, due to the complex geological structure of the coal seam, especially at the junction of the coal seam and hard rock layer, the drill rod of the drilling rig often experiences excessive resistance during drilling, which can easily lead to the breakage of the drill rod, making it impossible for the drilling tools to operate normally and affecting the geological drilling and exploration of the coalfield. Utility Model Content

[0021] 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.

[0022] Example 1: Please refer to Figures 1-4 A drilling rig for coalfield geological exploration includes a base 1 and a drilling rig assembly 2. The drilling rig assembly 2 is located at the upper end of the base 1. The base 1 is used to support the drilling rig assembly 2 and to complete the drilling exploration of coalfield geology with the help of the drilling rig assembly 2.

[0023] The drilling rig assembly 2 includes a movable structure 21 and a housing 22 mounted on the movable structure 21. A drive motor is installed inside the housing 22, and the output end of the drive motor passes through the housing 22 and is connected to the drill rod 23. A lubrication structure 24 is also installed on the movable structure 21. The lubrication structure 24 is used to spray lubricating oil onto the drill rod 23, thereby reducing the friction between the drill rod 23 and the coalfield geology, thus slowing down the wear on the drill rod 23 and preventing the drill rod 23 from breaking.

[0024] The movable structure 21 includes a fixed frame 211 and a motor 212 mounted on the upper end of the fixed frame 211. The output end of the motor 212 is connected to a lead screw 213, and the lead screw 213 is located inside the fixed frame 211. A slide 214 is threaded on the outer side of the lead screw 213. Bolts 216 are installed on the fixed frame 211, and the fixed frame 211 is fixed to the base 1 by means of bolts 216.

[0025] The outer wall of the lead screw 213 and the slide 214 are uniformly coated with a dustproof coating 215. The dustproof coating 215 helps to isolate dust from the lead screw 213 and the slide 214 and reduce wear.

[0026] The lubrication structure 24 includes a reservoir 241 containing lubricating oil and a micro pump 246 installed inside the reservoir 241. One end of the micro pump 246 is connected to a conduit 242, and the other end of the conduit 242 is connected to an annular tube 243. Several nozzles 244 are evenly distributed at the lower end of the annular tube 243. A protective cover 245 is also installed at the lower end of the housing 22. The protective cover 245 has a conical structure, and a mounting base 247 is installed at the top of the protective cover 245. The protective cover 245 can be fixed to the housing 22 by the cooperation of the mounting base 247 and screws, so that the protective cover 245 can cover the annular tube 243 and the nozzles 244, thereby achieving the purpose of protecting the annular tube 243 and the nozzles 244.

[0027] A baffle 11 is installed on the inner side of the base 1. The baffle 11 can play a good protective role and prevent personnel from being injured when the drill rod 23 breaks.

[0028] In this embodiment: During the process, the motor 212 is started, which drives the lead screw 213 to rotate. In conjunction with the slide 214, the machine housing 22 and the drill rod 23 move up and down. The dustproof coating 215 helps to isolate dust from the lead screw 213 and the slide 214, reducing wear. At the same time, the drive motor is started, which drives the drill rod 23 to rotate, allowing drilling exploration of the coalfield geology. Simultaneously, the pump body is started, which can extract the lubricating oil from the storage tank 241 and spray it out through the conduit 242, the annular pipe 243 and the nozzle 244. This allows the lubricating oil to be distributed on the drill rod 23, reducing the friction between the drill rod 23 and the coalfield geology, thereby slowing down the wear of the drill rod 23 and preventing it from breaking. Furthermore, the protective cover 245 moves with the machine housing 22, which can wrap the annular pipe 243 and the nozzle 244 to prevent the annular pipe 243 and the nozzle 244 from contacting the coalfield geology, thus achieving the purpose of protecting the annular pipe 243 and the nozzle 244.

[0029] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 The baffle 11 has a sliding plate 12 inside, and a drain pipe 13 is connected to the side wall of the baffle 11. One end of the drain pipe 13 is inserted into the baffle 11 and connected to a flushing pipe 14. The other end of the drain pipe 13 is connected to a water pump interface. Several nozzles are evenly distributed on the flushing pipe 14.

[0030] A pull rod 121 is installed at the upper end of the slide plate 12, and a positioning block 122 is fixedly installed at the lower end of the slide plate 12. A positioning groove 123 is provided on the inner bottom wall of the baffle 11, and the positioning groove 123 is the same size and shape as the positioning block 122. The slide plate 12 is slid inside the baffle 11 until the positioning block 122 is inserted into the positioning groove 123, which can block the flushing pipe 14 and the nozzle. Conversely, it can expose the flushing pipe 14 and the nozzle, and together with the drainage pipe 13 and the pump body, water can be sprayed out to flush the drill rod 23 and reduce the impurities adhering to the surface of the drill rod 23.

[0031] In this embodiment: when the drill rod 23 is drilling, the slide plate 12 is inside the baffle 11. At this time, the baffle 11 and the slide plate 12 can provide protection. After the drill rod 23 is removed from the geology, the slide plate 12 can be removed from the baffle 11 by holding the pull rod 121. At this time, the flushing pipe 14 is exposed, and water can be sprayed out by using the drainage pipe 13 and the pump body to flush the drill rod 23, reducing the impurities adhering to the surface of the drill rod 23. After flushing, the workers can use tools to wipe away the water.
