Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy and hydropower construction, and particularly relates to water conservancy drilling construction equipment. Background Art

[0002] Water conservancy and hydropower engineering focuses on the fundamental knowledge and skills of water resources, hydraulic structures, hydraulics and fluid dynamics, and hydraulic engineering technology. This discipline conducts the survey, planning, design, construction, and management of water conservancy and hydropower projects. Drilling equipment is often required during the construction phase of water conservancy and hydropower projects.

[0003] Existing drilling equipment has a casing on the outside of the drill bit for guidance, and a straightening mechanism on the outside of the drill bit to correct the drill hole and prevent deviation. During use, the straightening mechanism and casing are fixed underground, the drill bit passes through the casing to drill, and the casing and straightening mechanism are removed after use. However, during the drilling process, rock dust moves up and then falls back. Since there is a certain gap between the straightening mechanism and the casing, and they are installed separately, when the drill bit is working, the rock dust falls back, which will inevitably cause a large amount of rock dust to be generated between the casing and the straightening mechanism, which will make it impossible to remove the straightening mechanism and casing from the ground later. Summary of the Invention

[0004] In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a hydraulic drilling construction equipment, which solves the problem in the prior art that the straightening mechanism and the casing cannot be removed from the ground during the drilling process.

[0005] To achieve the above purpose, the technical solution provided by the present invention is:

[0007] With the above-mentioned structural design, the sealing disk is fixedly connected to the righting mechanism, and the gap between the righting mechanism and the casing is sealed, which can effectively prevent rock powder from entering and accumulating between the righting mechanism and the casing. The righting mechanism, casing and sealing disk are designed as an integrated whole, and the casing is driven up and down by the driving mechanism, which can prevent the righting mechanism and casing from being unable to be removed from the ground.

[0008] Preferably, the guide member is a cylindrical structure, and a disc connection is provided at the upper end.

[0009] With the above structural design, the guide member cooperates with the sleeve structure design to play a guiding role during the up and down movement of the sleeve. Since movable grooves are provided on both sides of the guide member, a disc is provided on the top to connect and fix the guide member.

[0010] Preferably, the sleeve and the sealing disk are integrally formed, and the sealing disk forms a mounting portion on the outside of the sleeve and a sealing portion on the inside of the sleeve, and a through hole communicating with the inside of the sleeve is opened in the middle.

[0013] With the above structural design, the base, the sealing disk and the sleeve are connected by a pressure rod. When the sleeve moves up and down, the pressure rod is subjected to pressure and can be retracted and extended.

[0015] With the above structural design, the upper end of the straightening mechanism is precisely connected and matched with the sealing part inside the sealing disk, and can be fixed together by integral molding or welding. The aperture size is large enough for the drill bit to pass through, thereby effectively sealing the gap between the casing and the straightening mechanism to prevent rock powder from falling in and accumulating during drilling.

[0016] Preferably, the driving mechanism includes a first fixed rod, a square frame, a connecting rod and a second fixed rod, one end of the first fixed rod is fixedly mounted on the guide member, and the other end is pivotally connected to the square frame, one end of the second fixed rod is fixedly connected to the sleeve in the movable groove, and the other end is pivotally connected to the connecting rod, and the other end of the connecting rod is pivotally connected to the upper end of the square frame.

[0017] With the above structural design, the rotation of the direction frame drives the connecting rod to move, thereby driving the sleeve to move up and down, so as to provide power for installing and removing the sleeve.

[0018] Preferably, driving mechanisms are provided on both sides of the sleeve to drive the sleeve to move up and down in the guide member.

[0019] With the above structural design, the forces on both sides are more evenly distributed during the removal of the cannula, making it easier to remove the cannula.

When the drilling rig is drilling, it can effectively prevent rock powder from entering and accumulating between the straightening mechanism and the casing. The straightening mechanism, casing and sealing disk are designed as an integrated whole. At the same time, the casing is driven up and down by the driving mechanism, which can prevent the straightening mechanism and casing from being unable to be removed from the ground due to rock powder accumulation.

The guide 2 is fixedly mounted on the base 1. A dragging handrail 1a is provided on one side of the base 1, and supporting feet 1b are provided around the lower end for supporting the water conservancy drilling construction equipment in contact with the ground after installation. The sleeve 3 is movably mounted in the guide 2 and passes through the lower end of the base 1 below, and the sealing disk 5 is formed at the lower end of the sleeve 3. Movable grooves 2a are provided on both sides of the guide 2, and the driving mechanism 4 is fixedly mounted outside the guide 2 and connected to drive the sleeve 3 to move up and down. The upper end of the straightening mechanism 6 is fixedly mounted in the sleeve 3 and connected to the sealing disk 5. In this embodiment, driving mechanisms 4 are provided on both sides of the sleeve 3 to drive the sleeve 3 to move up and down in the guide 2, which can ensure that the sleeve 3 is evenly stressed and easier to remove.

[0033] In this embodiment, the guide member 2 is a cylindrical structure, and a disc 2b is provided at the upper end for connection. Specifically, the guide member 2 is two arc-shaped guide plates, and movable grooves 2a are left on both sides for connecting and installing the driving mechanism 4. Therefore, the design of the above-mentioned disc 2b can connect and fix the two guide plates to ensure the stability of the entire guide member 2.

[0034] Please continue reading Figure 3The sleeve 3 and sealing disc 5 are integrally formed, with the sealing disc 5 forming a mounting portion 5a on the outside of the sleeve 3 and a sealing portion 5b inside the sleeve 3. A through-hole 5c is provided in the middle of the sealing disc 5, which communicates with the interior of the sleeve 3. The inner diameter of the straightening mechanism 6 is the same as the aperture of the through-hole 5c, and the top of the straightening mechanism 6 is fixedly connected to the sealing portion 5b to form a sealed structure. When drilling with a drilling rig, the size of the drill bit is adapted to the inner diameter of the straightening mechanism 6 and the aperture of the through-hole 5c. The top of the straightening mechanism 6 is connected via the internal sealing portion 5b, thereby ensuring that the gap between the straightening mechanism 6 and the sleeve 3 is sealed.

[0035] Furthermore, a plurality of pressure rods 7 are provided between the base 1 and the mounting portion 5a. The ends of the pressure rods 7 extend out of the bottom of the mounting portion 5a to form latches 7a. The pressure rods 7 can be retracted and extended under pressure, thereby ensuring the stability of the connection between the base 1 and the sealing disk 5 without affecting the vertical movement of the sleeve 3, that is, the removal of the sleeve 3. At the same time, the protrusions below form latches 7a, which can play a role in fixing the device during installation and use.

[0036] Specifically, the driving mechanism 4 includes a first fixed rod 4a, a square frame 4b, a connecting rod 4c and a second fixed rod 4d. One end of the first fixed rod 4a is fixedly mounted on the guide member 2, and the other end is pivotally connected to the square frame 4b. One end of the second fixed rod 4d is fixedly connected to the sleeve 3 in the movable groove 2a, and the other end is pivotally connected to the connecting rod 4c. The other end of the connecting rod 4c is pivotally connected to the upper end of the square frame 4b.

[0037] Working principle of the present invention:

[0038] When using the hydraulic drilling construction equipment of the present invention, the equipment is used in conjunction with the drilling equipment. When drilling is required, the equipment is pushed to the drill hole, and the driving mechanism 4 drives the casing 3 and the straightening mechanism 6 to move down and is installed on the ground for fixation, wherein the latch 7a is fixed on the ground. The drill bit is then inserted into the casing 3 and passes through the casing 3 and the straightening mechanism 6 to drill a hole. The design of the sealing disk 5 can seal and isolate the gap A between the straightening mechanism 6 and the casing 3, so that the rock powder generated by the drilling will not fall back into the gap and accumulate, and the straightening mechanism 6 will not be unable to be removed. After the drilling is completed, the casing 3 and the straightening mechanism 6 can be removed by simply rotating the square frame 4b of the driving mechanism 4.
