Description

Technical Field

[0001] This utility model relates to the field of water drilling technology, specifically to a water drilling bracket. Background Technology

[0002] A water drill, also known as an engineering drill, is a common tool for drilling holes in hard substrates such as concrete and stone. It is widely used in construction, elevator installation, interior decoration, and pipeline laying due to its ability to produce large-diameter holes with smooth walls. Furthermore, during drilling, a specialized support is typically used to fix and support the water drill, eliminating the need for manual force to control it, effectively ensuring operational safety, reducing labor intensity, and ensuring drilling accuracy.

[0003] However, to ensure the stability of the water drill rig, expansion bolts are usually used to fix it to the ground. After drilling is completed, the expansion bolts must be cut and removed, making the use of water drill rigs inconvenient. Especially when drilling multiple holes, each hole requires expansion bolts to fix the water drill rig, which is very time-consuming and labor-intensive. For example, when installing a motor in an elevator machine room, it is common to drill 6 to 10 holes. If expansion bolts are still used to fix the water drill rig, the workload will be significantly increased. Therefore, sometimes workers prefer to rely on manual operation of the water drill for drilling.

[0004] Therefore, researchers have designed some extendable water drill brackets. By using the telescopic function to adjust the overall length of the water drill bracket, the water drill bracket can be tightly supported in the working space, avoiding the use of expansion bolts to fix the water drill bracket, and effectively improving the ease of use of the water drill bracket.

[0005] However, the extension and retraction adjustment methods of these retractable water drill supports mainly fall into two categories: one is stepped adjustment, which achieves fixed length adjustment by inserting pins or fasteners into adjustment holes at different intervals on the extension rod; although this method is reliable in locking, the adjustment precision is limited, and it cannot achieve precise fine-tuning. Moreover, the extension range is limited by the preset hole positions, making it difficult to extend to the maximum or retract to the minimum under extreme conditions, resulting in insufficient flexibility. The other type is stepless adjustment, which is usually achieved through a rotating clamp or friction locking mechanism, and can be locked at any position within the preset range; however, this type of adjustment often suffers from insufficient locking force and the risk of slippage when supporting water drills in high-intensity operations, resulting in poor stability.

[0006] Whether it is a simple stepped adjustment or a stepless adjustment, the total extension range of the water drill bracket is relatively fixed, making it difficult to achieve optimization in both compact storage and maximum extension at the same time. When the bracket needs to be retracted to its shortest length for easy storage and transportation, or when it needs to be extended to its longest length to cope with special height conditions, the limitations of the existing structure are particularly obvious. Utility Model Content

[0010] Specifically, an anti-slip pad is provided on the side of the top plate away from the base.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a water drill bracket. Figure 1A three-dimensional structural diagram of a water drill bracket in an embodiment of the present invention is shown. The water drill bracket includes a base 1, a support rod 2 fixedly mounted on the base 1, and a telescopic sleeve rod assembly 3 fixedly mounted on the top of the support rod 2. A water drill lifting mounting seat 200 is provided on the support rod 2. The telescopic sleeve rod assembly 3 includes an outer tube 310 fixedly mounted on the top of the support rod 2, an adjustment mechanism 320 disposed on the top of the outer tube 310, a telescopic rod 330 inserted into the outer tube 310 through the adjustment mechanism 320, and a top plate 340 disposed on the top of the telescopic rod 330. Figure 2 A schematic diagram of the overall structure of the adjusting mechanism in an embodiment of this utility model is shown. Figure 3 The diagram shows a first cross-sectional view of the adjustment mechanism in an embodiment of the present invention. The adjustment mechanism 320 includes an adjustment seat 321 fixed to the top of the outer sleeve 310, a locking wheel 322 hinged to the adjustment seat 321, a tooth 3221 formed on the outer peripheral surface of the locking wheel 322, a first handle 323 fixedly connected to the locking wheel 322, and a first rack 324 passing through the adjustment seat 321. One end of the first rack 324 is fixedly connected to the telescopic rod 330 based on a first hand-tightening fastener 325 (e.g., a hand-tightening screw), and the other end of the first rack 324 is slidably connected to the outer peripheral surface of the outer sleeve 310. Please see Figure 3 The telescopic rod 330 is provided with a plurality of adjustment through holes 331 at intervals along its own length direction, and the first hand-tightening fastener 325 passes through one of the adjustment through holes 331. The adjusting mechanism 320 has a locked state and a released state. In the locked state of the adjusting mechanism 320, please refer to... Figure 3 The tooth 3221 meshes with the first rack 324; Figure 4 A second cross-sectional view of the adjustment mechanism in an embodiment of the present invention is shown. In the released state of the adjustment mechanism 320, the tooth 3221 disengages from the first rack 324.

[0025] The water drill bracket of this utility model has a telescopic sleeve assembly 3 that achieves a larger effective telescopic range than the traditional single adjustment method through the coordinated work of "stepped adjustment (adjustment through hole 331)" and "stepless adjustment (rack-locking wheel 322 mechanism)". It can meet the working requirements of extreme height and achieve a minimized storage volume. Moreover, the adjustment mechanism 320 is locked by the engagement of the locking wheel 322 and the first rack 324. The engagement area is large, the self-locking performance is good, and it is not easy to slip, which ensures the stability and safety of the water drill during operation and overcomes the disadvantage of easy loosening of stepless adjustment such as rotary clamp or friction locking mechanism.

[0026] This utility model uses an innovative hybrid adjustment mechanism 320 to organically combine stepped adjustment and stepless adjustment, achieving a larger extension ratio. This allows the water drill bracket to retract to a shorter length for easy carrying and storage, and to extend to a longer length to adapt to higher working conditions. At the same time, it can achieve stable and reliable locking at any extension position.

[0027] Figure 5 A cross-sectional structural schematic diagram of the adjusting seat in an embodiment of the present utility model is shown. The adjusting seat 321 is provided with an anti-detachment mechanism. The anti-detachment mechanism includes a receiving groove 410 formed on the adjusting seat 321, an anti-detachment hook 420 rotatably disposed in the receiving groove 410, and a torsion spring 430 placed in the receiving groove 410. The tail end of the anti-detachment hook 420 is rotatably disposed in the receiving groove 410, and the head end of the anti-detachment hook 420 extends out of the receiving groove 410. Please see Figure 5 The receiving groove 410 has a blocking part 411 formed inside, and the blocking part 411 is located on the rotation path of the anti-disengagement hook 420; the head end of the anti-disengagement hook 420 has a first hook part 421 formed, and the tail end of the anti-disengagement hook 420 has a second hook part 422 formed, and the orientation of the first hook part 421 and the orientation of the second hook part 422 are opposite; the two ends of the torsion spring 430 are respectively provided with a first elastic foot 431 and a second elastic foot 432, and the first elastic foot 431 and the second elastic foot 432 form a V-shaped structure. The first elastic foot 431 abuts against the inner wall of the receiving groove 410, and the second elastic foot 432 abuts against the second hook part 422. The second hook part 422 is pressed against the blocking part 411 by the elastic action of the torsion spring 430. Please see Figure 5 The first handle 323 has a protrusion 3231 formed on its side; in the locked state of the adjustment mechanism 320, the first hook 421 hooks the protrusion 3231.

[0028] When the user pulls down the first handle 323, causing the adjustment mechanism 320 to enter the locking state (i.e., the teeth 3221 of the locking wheel 322 engage with the first rack 324), the protrusion 3231 on the side of the first handle 323 also moves accordingly. At the same time as the locking action is completed, the first hook 421 of the anti-disengagement hook 420 will automatically rebound and hook the protrusion 3231 under the action of the torsion spring 430. This design constitutes a reliable mechanical safety, ensuring that the first handle 323 will not rotate due to accidental vibration or external impact in the locked state, thereby greatly improving the stability and safety of locking.

[0029] When unlocking is required, the user only needs to use their finger to gently push the head of the anti-disengagement hook 420 inward (i.e. towards the adjustment seat 321) so that the first hook 421 overcomes the elastic force of the torsion spring 430 and disengages from the protrusion 3231, thereby releasing the safety. Then, the user can normally lift the first handle 323 to switch the adjustment mechanism 320 to the released state.

[0030] Figure 6 This diagram shows a first cross-sectional view of the top plate and buffer structure in an embodiment of the present invention. Figure 7 The diagram shows a second cross-sectional view of the top plate and buffer structure in an embodiment of the present invention. An anti-slip pad 341 is provided on the side of the top plate 340 away from the base 1. This anti-slip pad 341 is typically made of a material with a high coefficient of friction and high elasticity (such as rubber, silicone, or polyurethane). The anti-slip pad 341 generates significant static friction with the building surface, effectively preventing horizontal slippage of the top plate 340 and ensuring the stability of the water drill bracket.

[0031] In some specific embodiments, please refer to Figure 6 and Figure 7 The top plate 340 is disposed on the top of the telescopic rod 330 based on the buffer structure 500. The buffer structure 500 includes a buffer seat 510 fixedly disposed on the telescopic rod 330, a buffer shaft 520 movably disposed in the buffer seat 510, and a buffer spring 530 sleeved on the buffer shaft 520. The top end of the buffer shaft 520 is fixedly connected to the bottom of the top plate 340, one end of the buffer spring 530 is connected to the bottom of the top plate 340, and the other end of the buffer spring 530 is connected to the top of the buffer seat 510. Please see Figure 6 and Figure 7 The telescopic rod 330 is provided with a first limiting member 540 in the radial direction, and the buffer seat 510 is fixedly mounted on the telescopic rod 330 based on the first limiting member 540; the buffer shaft 520 is provided with a long through hole 521, the long through hole 521 extends along the length direction of the buffer shaft 520, and the first limiting member 540 passes through the long through hole 521.

[0032] When the water drill support is pressed tightly between the top of the building and the ground, the buffer structure 500, under the action of spring preload, can provide a continuous and adaptive clamping force to the top plate 340, compensating for minor unevenness of the building's top surface and enhancing the stability of the support. Moreover, when the water drill starts or vibrates during operation, the buffer spring 530 can effectively absorb most of the vertical vibration, significantly reducing the noise and impact transmitted to the building structure, thus protecting the working environment and improving the comfort and safety of the operating equipment.

[0033] Figure 8 The diagram shows a three-dimensional structure of the base, support rod, water drill lifting mounting seat and outer tube in an embodiment of the present invention. The upper end of the support rod 2 is fixedly provided with a connector 21, and the bottom of the outer tube 310 is sleeved on the connector 21. The bottom of the outer tube 310 is fixedly connected to the connector 21 based on a second hand-tightening fastener 311. This means that the support rod 2 and the outer sleeve 310 are detachably fixedly connected, realizing modular assembly and convenient maintenance. By loosening or tightening the second hand-tightening fastener 311 (e.g., a hand screw), the support rod 2 and the upper telescopic sleeve assembly 3 can be quickly separated and connected without any additional tools, greatly facilitating transportation, storage, and on-site assembly. The way the connector 21 is inserted into the outer sleeve 310 provides sufficient contact and support area, ensuring effective force transmission and keeping the overall structure stable in operation. This design allows the support rod 2, connector 21, and telescopic sleeve assembly 3 to be produced and replaced as independent modules, which not only facilitates manufacturing and maintenance but also allows for the future use of support rods 2 of different lengths or specifications according to different user needs, improving the product's versatility and flexibility.

[0034] In some specific embodiments, please refer to Figure 8 The support rod 2 is fixedly provided with a second rack 22 along its own length direction; Figure 9 The diagram shows a top view of the water drill lifting mounting base in an embodiment of the present invention. The water drill lifting mounting base 200 has a receiving cavity 201 that runs vertically through it, and the support rod 2 is movably inserted through the receiving cavity 201. Figure 10 This diagram shows a cross-sectional view of the support rod and the water drill lifting mounting base in an embodiment of the present invention. A drive shaft 210 is rotatably mounted inside one side of the water drill lifting mounting base 200. The drive shaft 210 is perpendicular to the support rod 2, and both ends of the drive shaft 210 extend out of the water drill lifting mounting base 200 (see [reference]). Figure 8 and Figure 9 ); Please see Figure 10 A gear 211 is coaxially mounted on the drive shaft 210, and the gear 211 meshes with the second rack 22; please refer to Figure 8 and Figure 9 One end of the drive shaft 210 is provided with a second handle 220, which is perpendicular to the drive shaft 210. Please see Figure 8 and Figure 10 The water drill lifting mounting base 200 has a water drill mounting part 230 on one side surface.

[0035] When the user cranks the second handle 220, it drives the drive shaft 210 and gear 211 to rotate together. Since gear 211 meshes with the fixed second rack 22, the rotation of gear 211 is converted into linear movement of the entire water drill lifting mounting base 200 along the support rod 2. In this purely mechanical transmission mechanism, the transmission of gear 211 and the second rack 22 is smooth and usually has a self-locking characteristic, which allows the water drill to be stably suspended after being raised or lowered to any position without sliding down due to its own weight, ensuring operational safety. Driven by the second handle 220, using the lever principle, the user only needs to apply a small force to easily lift the heavy water drill, greatly reducing the intensity of operation and improving adjustment efficiency.

[0036] For details, please refer to Figure 10 At least two rolling shafts 240 are rotatably disposed within the receiving cavity 201. Both rolling shafts 240 are perpendicular to the support rod 2 and are located on the side away from the water drill mounting portion 230. The circumferential surface of any rolling shaft 240 is tangent to the side surface of the support rod 2. The side of the receiving cavity 201 away from the water drill mounting portion 230 will experience a tilting moment due to the installation of the water drill, causing a significant increase in sliding friction between the inner wall of the receiving cavity 201 on that side and the support rod 2. Therefore, the rolling shafts 240 are installed on this side to replace the direct sliding friction between the water drill lifting mounting base 200 and the support rod 2 through rolling friction. This effectively reduces the jamming sensation of the water drill lifting mounting base 200 during lifting, significantly reducing the force required to crank the handle for lifting and lowering, making operation easier and smoother.

[0037] For further details, please refer to Figure 9 The accommodating cavity 201 has clamping plates 251 fixedly installed on the inner walls of opposite sides, with the clamping plates 251 avoiding the rolling shaft 240. At least one side of the water drill lifting mounting base 200 has a locking through hole leading to the surface of the clamping plate 251, and a locking fastener 252 is installed in the locking through hole. This locking fastener 252 is typically a hand-tightening screw. When the water drill is raised to the target height, the user only needs to tighten the locking fastener 252 so that its end firmly abuts or presses against the surface of the clamping plate 251. This causes the clamping plate 251 to clamp the surface of the support rod 2 and generate a large static friction force, thereby completely restricting the movement of the water drill lifting mounting base 200. The locking fastener 252, together with the aforementioned self-locking function of the gear 211 rack, constitutes a two-level safety system, consisting of a primary and a secondary system. The gear 211 rack is responsible for the primary self-locking, while the locking fastener 252 acts as an independent, manually operable mechanical safety lock. Even if the gear 211 rack transmission fails under extreme conditions, the locking fastener 252 can physically lock the water drill lifting mounting base 200 and the support rod 2, providing reliable protection.

[0038] Moreover, water drills generate strong and continuous vibrations during operation. These vibrations act on the rack and pinion pair 211 for a long time, and there is a theoretically very small probability that this could lead to slight slippage. This additional locking fastener 252 can completely eliminate this potential risk and is particularly suitable for long-term, high-intensity continuous operation scenarios.

[0039] In addition, locking this fastener ensures that the water drill lifting mounting base 200 is completely stationary during the installation, disassembly, or maintenance of the water drill rig, providing a safe and stable working environment for the operator.

[0040] For further details, please refer to Figure 8 , Figure 9 and Figure 10 A handle 260 is fixedly provided on one side of the water drill lifting mounting base 200, and the handle 260 is located on the side away from the water drill mounting part 230. The presence of the handle 260 facilitates the user to assist in drilling. When drilling on the ground, the user can press down on the handle 260 with his hand to apply a stable downward pushing force.

[0041] In some specific embodiments, please refer to Figure 8 The base 1 is equipped with casters 11, the axis of rotation of which is perpendicular to the support rod 2, and the outer circumferential surface of which is tangent to the lower surface of the base 1. When the water drill bracket needs to be moved, the user only needs to tilt the water drill bracket backward so that the casters 11 at the rear of the base 1 contact the ground, and it can be easily moved to the target work position like a handcart. When the water drill bracket is placed in the working position, returning it to a vertical position will stably press the entire base 1 onto the ground. At this time, the casters 11 are no longer under load, avoiding the problem of the support stability being affected by wheel wobbling.

[0042] In some specific embodiments, the length of the support rod 2 is L1, and the length of the telescopic sleeve assembly 3 is L2, then: 2.5m≤L1+L2≤3.5m.

[0043] L1+L2 here represents the overall dimensions of the water drill rig under two extreme conditions: the overall length of the water drill rig when fully retracted is 2.5m, and the overall length of the water drill rig when fully extended is 3.5m.

[0044] The telescopic length range of the water drill bracket covers the common indoor clear height of mainstream domestic civil and industrial buildings (usually 2.5 meters to 3.3 meters). Whether it is a residence, office building, or machine room or equipment room, the water drill bracket can be easily tightened between the ceiling and the ground through its ultra-long stroke telescopic sleeve assembly 3, providing stable support for water drilling operations.

[0045] This invention utilizes an innovative hybrid adjustment mechanism 320 to organically combine stepped and stepless adjustment, achieving a greater extension ratio. This allows the rhinestone holder to retract to a shorter length for easy carrying and storage, while extending to a longer length to adapt to more demanding work environments. Simultaneously, stable and reliable locking is achieved at any extension position. Furthermore, the adjustment mechanism 320 is equipped with an anti-disengagement mechanism to ensure that the first handle 323 will not rotate due to accidental vibration or external impact when locked, thereby greatly improving the stability and security of the locking mechanism.

[0046] The top plate 340 is equipped with anti-slip pads 341, which generate significant static friction with the building surface, effectively preventing horizontal slippage of the top plate 340 and ensuring the stability of the water drill support. Furthermore, the top plate 340 is positioned on top of the telescopic rod 330 based on a buffer structure 500. When the water drill support is pressed tightly between the building top and the ground, the buffer structure 500, under the preload of the spring, provides a continuous and adaptive clamping force to the top plate 340, compensating for minor unevenness on the building top surface and enhancing the stability of the support. Moreover, when the water drill starts or vibrates during operation, the buffer spring 530 effectively absorbs most of the vertical vibration, significantly reducing noise and impact transmitted to the building structure, protecting the working environment and improving the comfort and safety of the operating equipment.

[0047] The support rod 2 and the outer sleeve 310 are connected by a detachable fixed connection, which allows the support rod 2, connector 21 and telescopic sleeve assembly 3 to be produced and replaced as independent modules. This not only facilitates manufacturing and maintenance, but also allows for the future matching of support rods 2 of different lengths or specifications according to different user needs, thus improving the versatility and flexibility of the product.

[0048] The water drill lifting mounting base 200 is connected to the support rod 2 via a gear 211 and a fixed second rack 22. The rotation of the gear 211 is converted into the linear movement of the water drill lifting mounting base 200 along the support rod 2. In this purely mechanical transmission mechanism, the transmission of the gear 211 and the second rack 22 is smooth and usually has a self-locking characteristic, which allows the water drill to be stably suspended after being raised or lowered to any position without sliding down due to its own weight, thus ensuring operational safety. Driven by the second handle 220, using the lever principle, the user only needs to apply a small force to easily lift the heavy water drill, greatly reducing the intensity of operation and improving adjustment efficiency. Furthermore, a locking fastener 252 is provided on one side of the water drill lifting mounting base 200. This locking fastener 252 is usually a hand-tightening screw. When the water drill is raised to the target height, the user only needs to tighten the locking fastener 252 so that its end tightly abuts or presses against the surface of the clamping plate 251. This will cause the clamping plate 251 to clamp the surface of the support rod 2 and generate a huge static friction force, thereby completely restricting the movement of the water drill lifting mounting base 200. The locking fastener 252 and the aforementioned gear 211 rack self-locking function constitute a main and secondary two-level safety system. The gear 211 rack is responsible for the main self-locking, while the locking fastener 252 acts as an independent, manually operable mechanical safety lock. Even if the gear 211 rack transmission fails under extreme working conditions, the locking fastener 252 can physically lock the water drill lifting mounting base 200 and the support rod 2, providing reliable protection. In addition, the water drill generates strong and continuous vibrations during operation. These vibrations act on the rack and pinion pair 211 for a long time, and there is a theoretically very small probability that this could lead to slight slippage. This additional locking fastener 252 can completely eliminate this potential risk, and is particularly suitable for long-term, high-intensity continuous operation scenarios. Furthermore, when installing, disassembling, or maintaining the water drill, locking this fastener can ensure that the water drill lifting mounting base 200 is completely stationary, providing a safe and stable working environment for the operator.

[0049] The telescopic length range of the water drill bracket (2.5 meters to 3.5 meters) covers the common indoor clear height of mainstream domestic civil and industrial buildings (usually 2.5 meters to 3.3 meters). Whether it is a residence, office building, or machine room or equipment room, the water drill bracket can be easily tightened between the ceiling and the ground through its ultra-long stroke telescopic sleeve assembly 3, providing stable support for water drilling operations.
