Abstract
Description
Technical Field
[0001] This invention relates to the field of construction equipment technology, specifically to an adjustable water drill hole-opening device. Background Technology
[0002] In the field of construction engineering, during actual construction or later use, it is often necessary to create secondary openings in completed structural parts such as walls and floors due to reasons such as missing pre-reserved openings, design changes, functional adjustments, or renovations. Currently, such opening operations commonly use mechanical drilling equipment such as water drills. To ensure stability and accuracy during the drilling process, traditional methods typically rely on expansion bolts to firmly fix the drilling equipment to the work surface.
[0003] However, this fixing method has significant drawbacks. First, the drilling process itself can cause localized damage to the wall or floor structure when driving in expansion bolts, potentially weakening the overall load-bearing capacity of the components, especially posing potential safety hazards to thin-walled walls, prestressed areas, or critical load-bearing parts. Second, building structures typically have complex embedded electrical wiring, water supply and drainage pipes, and other concealed facilities. Drilling for expansion bolts is difficult to precisely avoid these concealed works, easily leading to pipe ruptures, causing leaks, electrical faults, signal interruptions, and other problems, resulting in serious construction accidents. Once such damage occurs, repairs often require shutting down water and power, not only interrupting on-site construction and delaying the project, but also necessitating additional repairs and restoration of the damaged areas, increasing project costs. Summary of the Invention
[0004] This invention provides an adjustable water drill hole-opening device, which aims to securely, reliably, and non-destructively fix mechanical drilling equipment.
[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:
[0006] An adjustable water drill hole-opening device includes a pole fixing frame fixed to a foundation surface and a pole movable frame sleeved on it; the pole fixing frame has multiple height adjustment holes spaced apart along its length; the lower part of the pole movable frame is provided with a pole adjustment box; a first adjustment gear is rotatably installed on the inner side wall of the pole adjustment box; the teeth of the first adjustment gear pass through the pole adjustment holes opened on the pole movable frame and mesh with the height adjustment holes; a pin hole is provided on the top plate of the pole adjustment box; a pin is provided in the pin hole to fix the first adjustment gear; the first adjustment gear is connected to a height adjustment handle that drives its rotation.
[0007] The upper part of the upright movable frame is equipped with a fixed plate, which is movably installed in the height adjustment hole of the upright fixed frame by two mounting bolts. A horizontal movable frame is provided on the fixed plate along the horizontal direction. Multiple horizontal position adjustment holes are opened at intervals along the length of the horizontal movable frame. A horizontal adjustment slot is fitted on the horizontal movable frame, and the horizontal adjustment slot can only move horizontally along the length of the horizontal movable frame. A motor is installed at the top of the horizontal adjustment slot, and a drill bit is provided at the output end of the motor. A second adjustment gear is rotatably installed in the horizontal adjustment slot. The second adjustment gear meshes with the horizontal position adjustment hole. The second adjustment gear is fixedly connected to the horizontal adjustment handle set on the outer wall of the horizontal adjustment slot.
[0008] Furthermore, the connection between the pole adjustment box and the pole movable frame is a fixed connection.
[0009] Furthermore, the connection between the fixed plate and the movable frame of the upright is a fixed connection.
[0010] Furthermore, the bottom of the pole fixing frame is provided with a first fixing base, which is a plate-shaped structure.
[0011] Furthermore, a second fixed base is provided on the top of the movable pole frame, and the second fixed base is a plate-shaped structure.
[0012] Furthermore, the fixed connection is a bolted connection.
[0013] The present invention has the following beneficial effects:
[0014] This invention achieves accurate and repeatable positioning support for drilling equipment. The height of the upright support is adjusted via a first adjusting gear and a height adjusting hole in the height direction. The horizontal position of the drill is adjusted by a second adjusting gear engaging with a horizontal position adjusting hole in the horizontal direction. Finally, the working height of the drill is adjusted in real time via two bolts, achieving non-destructive drilling and completing bidirectional precise adjustment and positioning of both height and horizontal position. The operator can intuitively and reliably position the drill bit to the target coordinate point. Each adjusting hole corresponds to a fixed position, effectively avoiding deviations caused by visual inspection or experience in traditional methods, ensuring the accuracy of the drilling position. Simultaneously, the locking pin prevents displacement due to vibration or external forces during operation, improving the reliability and repeatability of positioning.
[0015] Furthermore, the device uses double fixing to firmly connect the uprights between the ground and the ceiling, forming a stable spatial force-bearing frame. This effectively absorbs and counteracts the reaction forces, vibrations, and torques generated during drilling, reducing equipment vibration and sway. This not only ensures a smooth and stable drilling process but also reduces the operator's labor intensity and skill dependence, making the operation safer and less strenuous.

Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0025] Please refer to Figure 1-7 This embodiment describes in detail an adjustable water drill hole-opening device, which includes a pole fixing frame 1 fixed to the foundation surface and a pole movable frame 2 sleeved on it; the pole fixing frame 1 has a plurality of height adjustment holes 12 spaced apart along its length direction; the lower part of the pole movable frame 2 is provided with a pole adjustment box 22; a first adjustment gear 23 is rotatably installed on the inner side wall of the pole adjustment box 22; the teeth of the first adjustment gear 23 pass through the pole adjustment holes 25 opened on the pole movable frame 2 and mesh with the height adjustment holes 12; a pin hole is provided on the top plate of the pole adjustment box 22; a pin 13 for fixing the first adjustment gear 23 is provided in the pin hole; the first adjustment gear 23 is connected to a height adjustment handle 24 that drives its rotation;
[0026] The upper part of the upright movable frame 2 is provided with a fixed plate 31. The fixed plate 31 is movably installed in the height adjustment hole 12 of the upright fixed frame 1 by two mounting bolts 37. A horizontal movable frame 32 is provided on the fixed plate 31 along the horizontal direction. Multiple horizontal position adjustment holes 36 are opened at intervals along the length direction of the horizontal movable frame 32. A horizontal adjustment slot 33 is fitted on the horizontal movable frame 32. The horizontal adjustment slot 33 can only move horizontally along the length direction of the horizontal movable frame 32. A motor 6 is provided at the top of the horizontal adjustment slot 33. A drill bit 7 is provided at the output end of the motor 6. A second adjustment gear 34 is rotatably arranged in the horizontal adjustment slot 33. The second adjustment gear 34 meshes with the horizontal position adjustment hole 36. The second adjustment gear 34 is fixedly connected to the horizontal adjustment handle 35 provided on the outer wall of the horizontal adjustment slot 33.
[0027] The upright support frame 1 is the stationary part of the device, providing stable support for the entire device. The upright support frame 1 can be made of DN65 steel pipe, with a length of 1500-2000mm. Multiple height adjustment holes 12 are opened at fixed intervals along its length. The distance between the two ends of each height adjustment hole 12 and the end of the upright support frame 1 is 150mm. The size of the height adjustment holes 12 is chosen to ensure effective engagement with the first adjusting gear 23 without excessively weakening the strength of the pole. The center lines of all height adjustment holes 12 are on the same straight line, and this straight line is parallel to the axis of the upright support frame 1. The range of height adjustment holes 12 covers the expected working height range of the device.
[0028] A pole adjustment box 22 is fixedly installed at the lower part of the pole movable frame 2. The pole adjustment box 22 is a rectangular mounting box. A first adjusting gear 23 is rotatably mounted on the inner side wall of the pole adjustment box 22 via bearings. The axis of the first adjusting gear 23 is perpendicular to the side plate surface of the pole adjustment box 22. To drive the first adjusting gear 23 to rotate, a height adjustment handle 24 is fixedly connected on its coaxial axis. The height adjustment handle 24 can be a crank handle or a straight handle with anti-slip texture. On the side wall of the pole movable frame 2, corresponding to the installation position of the first adjusting gear 23, a pole adjustment hole 25 is provided. The size of the pole adjustment hole 25 is slightly larger than the tooth tip circle diameter of the first adjusting gear 23. Its function is to provide a channel for the teeth of the first adjusting gear 23, so that the teeth can pass through the tube wall of the pole movable frame 2 and extend into the interior of the pole movable frame 2.
[0029] When the movable upright frame 2 is fitted onto the fixed upright frame 1, the teeth of the first adjusting gear 23, which passes through the upright adjusting hole 25, can mesh with the height adjusting hole 12 on the fixed upright frame 1. That is, the teeth of the first adjusting gear 23 extend into the height adjusting hole 12. When the gear rotates, the tooth surface abuts against the front and rear edges of the inner wall hole of the height adjusting hole 12, generating a driving force to move the movable upright frame 2 up and down. By rotating the first adjusting gear 23 through the height adjusting handle 24, the gear moves from one hole to an adjacent hole, thus achieving a fixed height change. Each height adjusting hole 12 represents a specific height position. In the non-driving state, a pin 13 is inserted into the pin hole at the top of the upright adjusting box 22 to fix the first adjusting gear 23. The pin 13 can abut against the teeth to prevent the first adjusting gear 23 from rotating in the opposite direction under the weight of the upper component after height adjustment, causing an unexpected height change.
[0030] Height adjustment working principle: Rotating the height adjustment handle 24 drives the first adjustment gear 23 to rotate. Since the first adjustment gear 23 meshes with the height adjustment hole 12 on the fixed upright bracket 1, the rotational motion of the first adjustment gear 23 is converted into the linear motion of the upright bracket 1. Because the axis of the first adjustment gear 23 is fixed together with the upright movable frame 2 through the upright adjustment box 22, the linear motion of the first adjustment gear 23 drives the entire upright movable frame 2 and all its components to move up and down relative to the upright fixed frame 1. When the target height is reached, stop rotating the height adjustment handle 24, insert the pin 13 through the pin hole on the upright adjustment box 22, and the pin 13 locks the teeth of the first adjustment gear 23. The teeth on the side of the first adjustment gear 23 are fixed by the height adjustment hole 12, and the teeth at the top are fixed by the pin 13, thus locking the device at that height.
[0031] A fixing plate 31 is fixedly installed on the upper part of the upright movable frame 2. The fixing plate 31 is movably installed in the height adjustment hole 12 of the upright fixed frame 1 by two mounting bolts 37. The fixing plate 31 is a thick steel plate, and its shape can be rectangular or square, and it is placed vertically. A horizontal movable frame 32 is fixedly installed on the side surface of the fixing plate 31 in the horizontal direction. The horizontal movable frame 32 is the reference track for horizontal adjustment and can be a rectangular steel guide rail. The horizontal movable frame 32 is installed perpendicular to the fixing plate 31 by bolts or welding. The length of the horizontal movable frame 32 covers the maximum stroke of horizontal adjustment.
[0032] Along the length of the horizontal movable frame 32, a plurality of horizontal position adjustment holes 36 are provided at constant intervals. The horizontal position adjustment holes 36 function similarly to the height adjustment holes 12, and their dimensions are matched with the second adjustment gear 34.
[0033] A horizontal adjustment slot 33 is fitted onto the horizontal movable frame 32. The horizontal adjustment slot 33 has a through hole that matches the cross-sectional shape of the horizontal movable frame 32. The horizontal adjustment slot 33 has a rectangular through hole, slightly larger than the horizontal movable frame 32, forming a sliding pair.
[0034] It is important to emphasize that the mating structure between the horizontal adjustment slot 33 and the horizontal movable frame 32 ensures that the horizontal adjustment slot 33 can only move horizontally along the length of the horizontal movable frame 32, and cannot rotate around it or move in other directions. Therefore, the cross-section of the horizontal movable frame 32 must be designed as a non-circular symmetrical shape, such as a rectangle or a circle with a keyway; the shape of the sliding hole inside the horizontal adjustment slot 33 must perfectly match it.
[0035] Inside the horizontal adjustment slot 33, a second adjustment gear 34 is rotatably mounted via bearings. The axis of the second adjustment gear 34 is perpendicular to the horizontal movement direction. The teeth of the second adjustment gear 34 mesh with the horizontal position adjustment hole 36 on the horizontal movable frame 32, achieving step adjustment in the horizontal direction. A horizontal adjustment handle 35 is fixedly connected to the outer wall of the horizontal adjustment slot 33 to drive the second adjustment gear 34 to rotate. Since the width of the horizontal adjustment slot 33 is greater than the width of the motor 6, the rotation of the adjustment handle 35 will not interfere with the motor 6. By rotating the handle 35, the second adjustment gear 34 meshes with the fixed horizontal position adjustment hole 36, thereby driving the entire horizontal adjustment slot 33 to move horizontally in a straight line along the horizontal movable frame 32.
[0036] The top of the horizontal adjustment slot 33 serves as a mounting platform to fix the motor 6, which is directly mounted using clamps or bolts. The motor 6 can be a handheld water drill or a dedicated electric drill. A drill bit 7 is mounted on the output end of the motor 6, with the appropriate drill bit selected based on the hole diameter and material. The motor 6 and drill bit 7 can move horizontally together with the horizontal adjustment slot 33. The fixing plate 31, the horizontal movable frame 32, the horizontal adjustment slot 33, and the motor 6 and drill bit 7 on them are fixed to the vertical movable frame 2 by inserting two mounting bolts 37 from the fixing plate 31 into specially designed bolt mounting holes on the vertical movable frame 2. Figure 7 As shown, the projection of the movable support frame 2 on the horizontal plane is set to be greater than the projection of the fixed support frame 1 on the horizontal plane, and the bolt mounting holes are positioned to avoid the fixed support frame 1. By operating the mounting bolts 37 and the horizontal adjustment handle 35, the operator can accurately position the drill bit 7 to any target coordinate point on the working surface, achieving safe and stable drilling operations.
[0037] Furthermore, the connection between the pole adjustment box 22 and the pole movable frame 2 is a fixed connection.
[0038] Furthermore, the connection between the fixed plate 31 and the movable support frame 2 is a fixed connection.
[0039] Furthermore, the bottom of the pole fixing frame 1 is provided with a first fixing base 11, which is a plate-shaped structure.
[0040] The first fixed base 11 is a plate-like structure, a rectangular steel plate with a thickness of 10-15mm, whose dimensions are much larger than the cross-section of the upright fixing frame 1 to provide a stable support surface. The center of the first fixed base 11 is welded and fixed to the bottom end of the upright fixing frame 1. Multiple mounting holes for fixing bolts are opened on the edge of the first fixed base 11. When the foundation surface is a structural plate, expansion bolts can be driven into the structural plate through the mounting holes to fix the upright fixing frame 1.
[0041] Furthermore, the top of the movable pole frame 2 is provided with a second fixed base 21, which is a plate-shaped structure.
[0042] To improve the overall stability of the device during drilling, especially its ability to resist torsional reaction forces when drilling larger diameter holes, this embodiment also includes a second fixed base 21 on top of the movable upright frame 2. The function of the second fixed base 21 is to fix the top of the movable upright frame 2 to the upper support structure, increasing the fixing area. The second fixed base 21 can also be a rectangular plate structure with a thickness of 10-15mm. An anti-slip rubber pad can also be provided on the top of the second fixed base 21 to protect the support surface and increase friction. If the upper support structure allows, a bolt fixing method similar to the first fixed base 11 can also be used.
[0043] To facilitate assembly and disassembly during use, in one specific embodiment, the fixed connection can be a bolted connection. For example, holes can be drilled at corresponding positions on the pole adjustment box 22 and the pole movable frame 2, and high-strength bolts can be used for fastening. Alternatively, the fixing plate 31 can be bolted to the pole body of the pole movable frame 2 in the same manner.
[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
