Technical Field

[0001] This utility model relates to the field of drilling equipment, and in particular to a hydraulic geological drilling device suitable for soft soil areas. Background Technology

[0002] Most existing geological drilling equipment uses mechanical rotary cutting technology, which utilizes the high torque of a diesel engine or electric motor to drive a sawtooth drill bit connected by multiple drill rods to rotate at high speed and cut through soil or rock layers. This type of equipment is not only large and heavy, but also has low operating efficiency. In addition, the steps of starting the diesel engine, cutting the rock, and rotating the drill rods all generate a lot of noise during the drilling process.

[0003] In addition, when this type of equipment is used in narrow areas, it is often difficult to meet the usage requirements due to the limitations of transportation and space occupation. The movement process also requires the use of large cranes, and it is not easy to adjust the position of the rotating hole. Utility Model Content

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0022] See Figure 1 and Figure 2 , Figure 1 and Figure 2 The present invention illustrates the specific structure of a hydraulic geological drilling device suitable for soft soil areas, including a first drill rod 1, a drill rod fixing and pressing device 2, a base 4, and wheels 5. The first drill rod 1 can pass through the drill rod fixing and pressing device 2 and the base 4. The drill rod fixing and pressing device 2 is located at the top of the base 4. The wheels 5 are located at the bottom of the base 4 and are used to move the entire hydraulic geological drilling device suitable for soft soil areas.

[0023] It should be noted that this hydraulic geological drilling device, suitable for soft soil areas, reduces noise pollution by using a drill rod fixing and pressing device 2 to press the first drill rod 1 into the ground. This invention also features two wheels 5 at the bottom of the base 4 for easy adjustment of the drilling position.

[0024] Specifically, the drill rod fixing and pressing device 2 includes a clamping plate 21 and a first drill rod fixing seat 22. The clamping plate 21 includes a first clamping plate 211 and a second clamping plate 212. The first drill rod 1 is clamped between the first clamping plate 211 and the second clamping plate 212. By increasing the friction between the first drill rod 1 and the clamping plate 21, the position of the first drill rod 1 is prevented from shifting during the process of pressing the first drill rod 1 into the ground.

[0025] Furthermore, the drill pipe fixing and pressing device 2 also includes a first drill pipe fixing seat 22, on which a pressing pump 221 is provided. The pressing pump 221 is connected to the first drill pipe 1 in a driving connection, and is used to drive the drill pipe fixing and pressing device 2 to press the first drill pipe 1 into the ground. In this embodiment, the pressing pump 221 consists of two hydraulic jacks, which are symmetrically arranged on the first drill pipe fixing seat 22 to ensure the balance on both sides of the first drill pipe fixing seat 22.

[0026] Specifically, the hydraulic geological drilling device applicable to soft soil areas also includes an automatic rod connecting device 3, which is located on the top of the base 4. The automatic rod connecting device 3 is hinged to the drill rod fixing and pressing device 2. The automatic rod connecting device 3 includes a second drill rod, which can connect the second drill rod to the top of the first drill rod 1 in the drill rod fixing and pressing device 2, so that the end of the second drill rod near the first drill rod 1 is connected to the top of the first drill rod 1.

[0027] Furthermore, the automatic rod connecting device 3 also includes a rotary motor 31, a support plate 32, and a lifting pump 33. The rotary motor 31 is mounted on the support plate 32, and one end of the support plate 32 is hinged to the base 4. The movable end of the lifting pump 33 is hinged to the support plate 32, and the lifting pump 33 can drive the support plate 32 to swing on the base 4. The rotary motor 31 can connect the second drill rod to the top of the first drill rod 1 in the drill rod fixing and pressing device 2.

[0028] The movable end of the rotary motor 31 is connected to one end of the second drill rod. After the lifting pump 33 drives the support plate 32 to swing on the base 4, the axis of the second drill rod and the axis of the first drill rod 1 are on the same straight line. The end of the second drill rod away from the rotary motor 31 can be screwed to the top of the first drill rod 1.

[0029] In this embodiment, after the drill rod fixing and pressing device 2 presses the first drill rod 1 into the ground, the automatic rod connecting device 3 starts working. After the second drill rod is placed in the automatic rod connecting device 3, the rotary motor 31 rotates and tightens the second drill rod through transmission torque. After the second drill rod and the rotary motor 31 are fully tightened, the lifting pump 33 drives the support plate 32 to adjust from horizontal to vertical, so that the head end of the second drill rod 1 is completely aligned with the end end of the first drill rod 1. After complete alignment, the rotation motor 31 is used to loosen it, and the clamping plate 21 clamps the second drill rod. Then, the pressing pump 221 drives the second drill rod into the ground. At the same time, the support plate 32 is adjusted from vertical to horizontal under the drive of the lifting pump 33 to prepare for the next rod replacement.

[0030] See Figure 3 The first drill rod 1 has a hollow structure and a through hole 11 is provided on the wall of the first drill rod 1. The through hole 11 is connected to the interior of the first drill rod 1. Preferably, the first drill rod 1 can be connected to a water supply pipe at the top through hole 11, and the side resistance of the first drill rod 1 during the pressing process can be reduced by water flowing out from other through holes 11 on the rod wall.

[0031] Furthermore, the first drill rod 1 is composed of multiple sections, each section of the first drill rod 1 is connected by threads, and the top of the first section of the first drill rod 1 is provided with a conical angle 12 of 45°□75°, so as to maximize the drilling capacity of the first drill rod 1. Preferably, the conical angle 12 provided at the top of the first section of the first drill rod 1 is 60°, at which angle the first drill rod 1 has the strongest drilling capacity.

[0032] Specifically, the base 4 includes a working platform 41 and a lifting pile 42. The lifting pile 42 is located at the bottom of the working platform 41 and is used to support the working platform 41.

[0033] In this embodiment, four lifting piles 42 are provided, all located at the corners of the working platform 41, to ensure the stability of the entire hydraulic geological drilling device suitable for soft soil areas. All four lifting piles 42 are hydraulic lifting piles, which can automatically adapt to or be manually controlled in terms of their contact with the ground to better support the platform and ensure the overall stability and verticality of the drilling process.

[0034] Preferably, the hydraulic geological drilling device suitable for soft soil areas also includes a towing bracket 6 for connecting to the work vehicle. The towing bracket 6 is located on the outside of the work platform 41 and can be connected to a general work vehicle for long-distance transportation.

[0035] As can be seen from the above, this utility model achieves efficient and automated drilling by setting up a drill rod fixing and pressing device 2 and an automatic rod connecting device 3; at the same time, by setting up a traction bracket 6 and wheels 5, the hydraulic geological drilling device suitable for soft soil areas is made easier to move.

[0036] Furthermore, due to its small size, this hydraulic geological drilling device, suitable for soft soil areas, can also be used in places inaccessible to larger drilling equipment. Because it uses a hydraulic system for drilling, high-speed cutting is no longer required compared to traditional drilling equipment, reducing noise and environmental pollution. The first drill rod 1, with its hollow structure and through-holes 11 in its wall, can be connected to a water supply pipe. Water exiting through the through-holes 11 effectively reduces the impact of lateral resistance, thereby improving drilling efficiency and quality.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
