Description

Technical Field

[0001] This application belongs to the field of well construction operation technology, specifically relating to a well drilling device. Background Technology

[0002] Currently, drilling operations above manholes generally rely on manual labor. Workers need to carry handheld impact drills or cutting equipment to drill holes in the concrete or masonry walls of the manhole. This process has significant drawbacks: First, the working space is extremely limited and the environment is complex. It is very inconvenient for workers to operate heavy equipment, making it difficult to accurately control the drilling position and size, which can easily lead to positional deviations or irregular hole diameters, affecting the sealing and smoothness of subsequent pipeline connections. Second, the drilling process is high-intensity, physically demanding labor. The continuous impact and vibration cause significant physical exertion and fatigue for workers, resulting in low efficiency and difficulty in maintaining accuracy over long periods, with errors easily accumulating.

[0003] More seriously, manual drilling is accompanied by significant safety risks and cost issues. The operation generates large amounts of dust, debris, and noise, seriously endangering workers' respiratory health and hearing, and posing a risk of injury from flying debris. Simultaneously, the impact and vibration may cause unknown damage to existing well structures and internal pipelines. Furthermore, manual work is inefficient and time-consuming, significantly extending the project cycle and increasing labor costs and indirect economic losses due to construction delays. Therefore, a safer, more efficient, and precise alternative is urgently needed to overcome the many drawbacks of existing purely manual operations. Utility Model Content

[0004] The purpose of this application is to provide a well drilling device that solves the problems of low efficiency, poor quality, and high risk in existing manual well drilling.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A well drilling device includes a clamping assembly with an inverted U-shaped structure. The outer side of the clamping assembly is connected to the inner end of a drilling assembly via an arc-shaped transition assembly. The arc-shaped transition assembly includes a connecting plate, an arc-shaped sliding hole, and a locking pin. The outer side of the clamping assembly is connected to the connecting plate, which has an arc-shaped sliding hole. A locking pin is provided inside the arc-shaped sliding hole and is connected to the inner end of the drilling assembly.

[0007] Furthermore, the clamp assembly includes a frame, which has an inverted U-shaped structure. A vertical pressing component is provided on the crossbeam at the top of the frame, and horizontal top supports are provided on both sides of the frame.

[0008] Furthermore, the frame is a frame structure welded together from horizontal bars, vertical bars, and elongated bars.

[0009] Furthermore, the crossbeam is sleeved longitudinally on the frame.

[0010] Furthermore, the vertical pressing component includes an adjusting screw, the threaded section of which is threadedly connected to the crossbeam, the lower end of which is connected to the pressure plate, and the upper end of which is connected to the handle.

[0011] Furthermore, the horizontal support component includes a support screw, the threaded end of which is threadedly connected to the frame body.

[0012] Furthermore, at least two horizontal support members are provided on both sides of the frame.

[0013] Furthermore, the connecting plate is provided with at least two concentric arc-shaped sliding holes.

[0014] Furthermore, the drilling assembly includes a drilling track, on which a drilling rig travels along the track, and a drill bit is provided at the inner end of the drilling rig.

[0015] Furthermore, the drilling track is provided with a travel slide, and the drilling rig is provided with a slider that slides on the travel slide.

[0016] Furthermore, the drilling track is equipped with a traveling rack, and the drilling rig is equipped with a traveling motor, the gear of the traveling motor meshing with the traveling rack.

[0017] The beneficial effects of this application are:

[0018] (1) The drilling operation of the well is realized by mechanized equipment, which avoids the problems of low efficiency, poor quality and high risk of manual operation. It can reduce the labor intensity of manual operation, ensure the quality and accuracy of the final hole, and greatly improve the efficiency of construction operation.

[0019] (2) The device is installed at the wellhead of the pipe well by means of the clamping assembly.

Detailed Implementation

[0027] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0028] refer to Figures 1-4 As shown, a well drilling device includes a clamping assembly 200, an arc-shaped transition assembly 300, and a drilling assembly 400.

[0029] The clamping assembly 200 has an inverted U-shaped structure. It is used to clamp the device at the wellhead of the wellbore 100; that is, the clamping assembly 200 is directly inverted and fixed to the wellbore 100, providing a stable foundation for the drilling assembly 400. After the clamping assembly 200 is released, the circumferential and vertical positions of the drilling assembly 400 can be adjusted along the wellbore 100.

[0030] The outer side of the clamping assembly 200 is connected to the inner end of the drilling assembly 400 through the arc-shaped transition assembly 300. The arc-shaped transition assembly 300 realizes the rotational connection between the clamping assembly 200 and the drilling assembly 400, so as to adjust the circumferential position of the drilling assembly 400 by a small range and ensure the working accuracy of the drilling assembly 400.

[0031] The drilling assembly 400 is used for specific hole drilling. It has a radial travel function and a rotating drill bit, which can complete the functions of forward drilling and retraction after hole completion.

[0032] The clamp assembly 200 includes a frame 201, a crossbeam 202, an adjusting screw 203, a pressure plate 204, a handle 205, and a top support screw 206. The frame 201 is the main frame of the clamp assembly 200, and the frame 201 has an inverted U-shaped structure, which is installed at the wellhead with an inverted snap-fit. Preferably, the frame 201 is a frame structure welded together with crossbars, longitudinal bars, and vertical bars.

[0033] A vertical pressing component is provided on the crossbeam 202 at the top of the frame 201. The vertical pressing component presses the frame 201 onto the top surface of the wellhead, keeping the vertical position of the frame 201 fixed. Horizontal support components are provided on both sides of the frame 201. The horizontal support components support the frame 201 on the sides of the wellhead, keeping the radial position of the frame 201 fixed.

[0034] The crossbeam 202 is fitted onto the frame 201 longitudinally (radially), so the radial position of the vertical pressing component can be adjusted, thereby adjusting the position of the pressing action. The crossbeam 202 and the frame 201 can be locked together with screws, or the reaction force from the vertical pressing component can be used to create friction between the crossbeam 202 and the frame 201 to achieve position locking.

[0035] The vertical pressing component includes an adjusting screw 203, a pressure plate 204, and a handle 205. The threaded section of the adjusting screw 203 is threadedly connected to the crossbeam 202, and the vertical height is adjusted by rotating the adjusting screw 203. The lower end of the adjusting screw 203 is welded to the pressure plate 204, which provides specific pressing contact to the top surface of the wellhead. The upper end of the adjusting screw 203 is welded to the handle 205, facilitating rotation of the adjusting screw 203.

[0036] The horizontal support component includes a support screw 206, the threaded end of which is threadedly connected to the frame 201. Tightening or loosening is achieved by rotating the support screw 206, which together compresses the wellhead sidewall from both sides, thus fixing the radial position. At least two horizontal support components are provided on each side of the frame 201 to ensure reliable and secure horizontal support on each side.

[0037] The arc-shaped transition component 300 includes a connecting plate 301, an arc-shaped sliding hole 302, and a locking pin 303. The outer side of the clamping component 200, i.e., the outer side of the frame 201, is welded to the connecting plate 301. The connecting plate 301 has an arc-shaped sliding hole 302. After the device is installed, the center of the arc-shaped sliding hole needs to be aligned with the center of the well 100. The locking pin 303 is installed inside the arc-shaped sliding hole 302, and the locking pin 303 is connected to the inner end of the drilling component, i.e., the inner end of the drilling track 401.

[0038] Loosening the locking pin 303 allows for a small range of circumferential position adjustment of the drilling assembly 400 relative to the clamping assembly 200. If the clamping assembly 200 is not positioned precisely, the drilling assembly 400 can be directly adjusted, avoiding repeated adjustments to the clamping assembly 200 and delaying construction. Tightening the locking pin 303 secures the drilling assembly 400 relative to the clamping assembly 200.

[0039] The connecting plate 301 is provided with at least two concentric arc-shaped sliding holes 302 to ensure the stability of the connection transition and avoid the problem of instability of a single arc-shaped sliding hole 302.

[0040] The drilling assembly 400 includes a drilling track 401, a drilling rig 402, and a drill bit 403. The drilling rig 402, which travels along the drilling track 401, is mounted on the drilling track 401. The drill bit 403 is mounted on the inner end of the drilling rig 402. The drilling rig 402 moves back and forth along the drilling track 401, driving the drill bit 403 to move radially forward or backward. At the same time, the drilling rig 402 drives the drill bit 403 to rotate, drilling into the well wall.

[0041] The drilling track 401 is equipped with a travel slide, and the drilling rig 402 is equipped with a slider that slides on the travel slide to ensure smooth and stable movement of the drilling rig 402. The drilling track 401 is equipped with a travel rack, and the drilling rig 402 is equipped with a travel motor. The gear of the travel motor meshes with the travel rack to achieve forward and backward movement.

[0042] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
