[0001] The utility model relates to the technical field of exploration hole expansion, in particular to a hole expander for engineering investigation. Background Technique
[0002] An exploration hole expander is a device specifically designed for geological exploration. It can further expand the hole diameter on the basis of an existing drill hole to facilitate subsequent operations. During geological exploration, the hole-expanding drill continuously expands the drill hole diameter by drilling deep into the ground along the drill hole. During this process, the hole-expanding drill rotates at high speed, breaks the contacting soil and rock layers, and flushes the soil and rock layers out of the drill hole through the impact force of water flow;
[0003] The underground structure is very complex and there are many crushed stones. The phenomenon of the hole-expanding drill getting stuck often occurs because the crushed stones in the drill hole are not flushed out of the drill hole, resulting in the accumulation of rock debris. This phenomenon may not only damage the equipment, but also be extremely difficult to handle because the drill hole is narrow and the hole-expanding drill is stuck. Content of the Utility Model
[0004] The purpose of the utility model is to provide a hole expander for engineering investigation to solve the problems raised in the above background technique.

[0026] Embodiment 1:
[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution: including a drill rig 1, a lifting platform 2 slidably connected in the drill rig 1, and a suspension box 3 fixedly connected to the lower surface of the lifting platform 2. A mechanism 4 for cleaning crushed stone chips is arranged below the suspension box 3, and a lifting mechanism 5 is arranged outside the suspension box 3;
[0028] The mechanism 4 for cleaning crushed stone chips includes a cleaning component 41 and a crushed stone component 42, and the cleaning component 41 is arranged inside the crushed stone component 42;
[0029] The cleaning component 41 includes a drilling motor 411. The drilling motor 411 is fixedly connected inside the suspension box 3. The output end of the drilling motor 411 penetrates through the bottom of the suspension box 3 and extends to the lower side of the suspension box 3. A drill pipe 412 is fixedly connected to the output end of the drilling motor 411. The drill pipe 412 is hollow inside. A reaming drill 413 is fixedly connected to the bottom of the drill pipe 412. A fixing rod 414 is fixedly connected to the lower surface of the suspension box 3. A connecting box 415 is fixedly connected to the lower end of the fixing rod 414. A liquid outlet 416 is formed at the bottom of the reaming drill 413. The liquid outlet 416 communicates with the outside of the reaming drill 413. A notch is formed on the drill pipe 412. The connecting box 415 communicates with the liquid outlet 416 through the notch. An output gear 417 is fixedly connected to the upper end of the drill pipe 412. A rotating shaft gear 418 is meshed and connected to one side of the output gear 417. During the drilling process of the reaming drill 413, water flow is conveyed to the liquid outlet 416 through a pipeline fixedly connected to the connecting box 415. The water flow flushes the stone chips drilled by the reaming drill 413 and cools the reaming drill 413. The connecting box 415 is rotatably connected to the rotating drum, and at the same time, the connecting box 415 is fixed by the fixing rod 414, so that the water flow can be sent to the position of the reaming drill 413 without affecting the rotation of the reaming drill 413.
[0030] Further, a shaft rod is rotatably connected inside the rotating shaft gear 418. The shaft rod is fixedly connected to the bottom of the suspension box 3. The rotating shaft gear 418 meshes and rotates during the rotation of the drill pipe 412, which is convenient for driving the rotating drum 422 to rotate subsequently.
[0031] Further, multiple rows of taper teeth with different sizes are arranged on the reaming drill 413. Driven by the reaming drill 413, the taper teeth scrape the small stones in contact from the inner wall of the drill hole.
[0032] Further, there are multiple liquid outlets 416. The liquid outlets 416 are evenly distributed at the bottom of the reaming drill 413. The even distribution of the liquid outlets 416 effectively disperses the impact of the water flow on the drill hole.
[0033] Further, the gravel component 42 includes a driven gearbox 421 and a drill barrel 422. The drill barrel 422 is arranged on the lower side of the suspension box 3. The drill barrel 422 is rotatably connected to the drill pipe 412. The driven gearbox 421 is fixedly connected to the upper end of the drill barrel 422. A grinding head 423 is fixedly connected to the lower end of the drill barrel 422. An L-shaped rod is fixedly connected to the lower end of the suspension box 3. A slurry box 424 is fixedly connected to the lower end of the L-shaped rod. The slurry box 424 is rotatably connected to the outside of the drill barrel 422. A slurry extraction channel 425 is formed in the grinding head 423 and the drill barrel 422. The slurry box 424 is communicated with the outside of the grinding head 423 through the slurry extraction channel 425. A slurry extraction pipe 426 is communicated with one side of the slurry box 424. A rack 427 is fixedly connected to the upper end of the drill barrel 422. The rack 427 is meshed with the rotating shaft gear 418. The drill barrel 422 and the rotating rod rotate in opposite directions under the action of the rotating shaft gear 418, so that the gravel structure between the reaming drill 413 and the grinding head 423 crushes the contacting stones. The slurry extraction channel 425 is arranged in the middle of the bottom end of the grinding head 423. Under the action of the slurry extraction pipe 426, the slurry extraction pipe 426 can be externally connected to a pump to suck out the slurry. During this process, the stones lifted by the scouring water flow at the reaming drill 413 are more likely to be sucked by the slurry extraction pipe 426 to the space between the grinding head 423 and the reaming drill 413, preventing gravel accumulation.
[0034] Further, the connection box 415 is rotatably connected to the outside of the drill barrel 422. The connection box 415 communicates with the inside of the drill pipe 412 without affecting the rotation of the drill pipe 412.
[0035] Embodiment 2:
[0036] Please refer to Figures 1-5 and in combination with Embodiment 1, it is further obtained that the lifting mechanism 5 includes a tooth column 501. The tooth column 501 is fixedly connected to the drill rig 1. A lifting motor 502 is fixedly connected to the lower surface of the lifting platform 2. The output end of the lifting motor 502 is fixedly connected to a meshing tooth 503. The meshing tooth 503 is meshed with the tooth column 501. Controlling the descending speed of the drill pipe 412 by the lifting motor 502 is beneficial to protecting the reaming drill 413 because different rock formations require different drilling speeds, and the rotation speed of the lifting motor 502 can be controlled by a sensor.
[0037] During the actual operation process, when this device is used, the user can control the height of the lifting platform 2 through the lifting motor 502. Water pressure is provided through a pipeline in the connection box 415, and suction is provided through the slurry extraction pipe 426 in the slurry extraction box. The drilling motor is started. The drilling motor drives the drill pipe 412 to rotate. The drill pipe 412 drives the reaming drill 413 to ream and wash the rock chips. The rotating rod drives the rotating cylinder to rotate in the opposite direction to the rotating rod through the rotating shaft gear 418. During the process of the reaming drill 413 washing the rock chips, the slurry extraction pipe 426 sucks the washed rock chips to the space between the reaming drill 413 and the grinding head 423 through the grinding head 423. The grinding tools arranged on the reaming drill 413 and the grinding head 423 crush the stones and then flow out through the slurry suction pipe.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.
