Description

Technical Field

[0001] This utility model relates to the technical field of building leak repair equipment, and in particular to a crack cleaning device for building leak repair. Background Technology

[0002] In the routine maintenance and repair of buildings, especially during waterproofing and leak repair, the first step is usually to clean any cracks in the walls, floors, or ceilings to ensure that the subsequent filling repair material can bond firmly to the substrate. Currently, construction workers commonly use handheld electric grinders or cutters to complete this task.

[0003] These handheld tools perform adequately when dealing with cracks within the normal operating height range of a person, meeting basic cleaning needs. However, cracks in building structures come in a variety of locations, with a significant number appearing in ceilings, high walls, and other areas requiring work at height.

[0004] In this situation, the limitations of existing handheld tools become apparent. Due to their fixed and relatively short overall length, operators must use ladders, scaffolding, or other auxiliary equipment, and must maintain an elevated arm position for extended periods. This not only significantly increases the operator's workload, easily leading to arm pain and fatigue, but more importantly, fatigue significantly reduces the stability and precision of tool handling, affecting the quality of crack cleaning and creating safety hazards due to tool slippage or operational errors.

[0005] Therefore, this utility model proposes a crack cleaning device for building leak repair to overcome the shortcomings of the prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a crack cleaning device for building leak repair, which solves the problem that the overall length of existing crack cleaning devices for building leak repair is fixed, resulting in laborious operation, unstable grip, and safety hazards when cleaning cracks at high places.

[0007] To achieve the above objectives, this utility model provides a crack cleaning device for building leak repair, comprising: a protective shell, a grinding wheel, a telescopic mechanism; and a locking component and an auxiliary block.

[0008] The telescopic mechanism includes a fixed column with one end fixedly connected to the rear side of the protective shell, and a sliding column that is slidably sleeved inside the fixed column.

[0009] Furthermore, the locking component is located inside the sliding column and is used to lock the relative position of the sliding column and the fixed column. The locking component includes a sliding block arranged radially along the sliding column, a telescopic column connected to the inner end of the sliding block, and a spring sleeved on the telescopic column with its two ends abutting against the inner wall of the sliding column and the telescopic column, respectively; the auxiliary block is fixedly connected to the outer wall of the sliding column.

[0010] Preferably, the crack cleaning equipment for building leak repair further includes an adjustment mechanism, which is installed on the protective shell and is used to limit the length of the grinding wheel extending out of the protective shell.

[0011] Preferably, the adjustment mechanism includes a limiting block that slides in contact with the side of the grinding wheel, and a stud that passes through the protective shell perpendicular to the sliding direction of the grinding wheel and is threadedly connected to the limiting block.

[0012] Preferably, the adjustment mechanism further includes a fixing component, which includes a rotating column and a rotating plate. The rotating column is fixed to the protective shell, and one end of the rotating plate is rotatably connected to the protective shell through the rotating column, while the other end is used to selectively abut against the grinding wheel for auxiliary fixing.

[0013] Preferably, the fixed column has multiple positioning holes along its axial direction on its tube wall. Under the action of the spring force, the outer end of the telescopic column passes through the tube wall of the sliding column and is locked into one of the positioning holes, thereby achieving locking.

[0014] Preferably, pressing the sliding block causes the telescopic column to move radially within the sliding column and compress the spring, thereby causing the outer end of the telescopic column to disengage from the positioning hole to release the lock.

[0015] Preferably, by rotating the stud in the forward or reverse direction, the limiting block can be driven to move along the axial direction of the stud, thereby achieving clamping and fixing or sliding release of the grinding wheel.

[0016] Preferably, the crack cleaning device for building leak repair also includes an electric wire, one end of which is connected to an external power source, and the other end passes through the interior of the telescopic mechanism and is electrically connected to a built-in motor that drives the grinding wheel to rotate.

[0017] 1. In this utility model, by setting a telescopic mechanism consisting of a fixed column, a sliding column and a spring locking assembly, the problem of the fixed overall length of existing crack cleaning tools, which leads to laborious operation and safety hazards when cleaning cracks at high altitudes, is solved. The technical effect of being able to conveniently adjust the total length of the equipment, easily adapt to different height operation needs, and improve the convenience and safety of high-altitude operation is achieved.

[0018] 2. In this utility model, by setting an adjustment mechanism consisting of a limiting block, a stud, and a fixing component, the problem that the exposed length of the grinding wheel of existing tools is not adjustable and it is difficult to effectively clean cracks of different depths is solved. The technical effect of being able to accurately control the extension length of the grinding wheel and flexibly adapt to various crack depths is achieved, thereby improving the cleaning quality and equipment applicability.

[0019] 3. This utility model solves the problem of unstable grip and fatigue for operators when holding equipment at heights by adding an auxiliary block to the retractable sliding column. It enhances the grip stability of the equipment during high-altitude operations, effectively reduces arm pain for operators, further ensures construction safety, and improves work efficiency.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example: Please refer to Figures 1 to 5This utility model provides a crack cleaning device for building leak repair, which aims to solve the problem that the existing crack cleaning tools have a fixed cutting depth and overall length, making them difficult to adapt to different working scenarios at different depths and heights, and there is a safety hazard of unstable grip when operating at heights.

[0025] like Figure 1 As shown, the crack cleaning equipment for building leak repair includes a protective shell 1, a grinding wheel 2 set inside the protective shell 1, a telescopic mechanism 4 for adjusting the overall length of the equipment, and an adjustment mechanism 3 for adjusting the extension length of the grinding wheel 2. One end of the telescopic mechanism 4 is fixedly connected to the rear side of the protective shell 1, the adjustment mechanism 3 is installed on the protective shell 1, and the wire 5 passes through the interior of the telescopic mechanism 4 and is electrically connected to the built-in motor that drives the grinding wheel 2 to rotate. Specifically, refer to Figure 1 , Figure 4 and Figure 5 The telescopic mechanism 4 includes a fixed column 41 and a sliding column 42. One end of the fixed column 41 is fixedly connected to the rear end of the protective shell 1. The sliding column 42 is slidably sleeved inside the fixed column 41. In order to lock the sliding column 42 at any extended position inside the fixed column 41, a locking component is also provided inside the sliding column 42. Furthermore, the locking assembly includes a sliding block 45, a telescopic post 43, and a spring 44. The sliding block 45 is radially arranged along the sliding post 42 and extends through the tube wall of the sliding post 42. The telescopic post 43 is disposed inside the sliding post 42, and its inner end is fixedly connected to the inner end of the sliding block 45. The spring 44 is sleeved on the telescopic post 43, and its two ends abut against the inner wall of the sliding post 42 and the flange on the telescopic post 43, respectively, to provide a restoring elastic force. To achieve locking, multiple positioning holes are formed along the axial direction on the tube wall of the fixed post 41. Under the elastic force of the spring 44, the telescopic post 43... The outer end is pushed out and passes through the tube wall of the sliding column 42, and then gets stuck in one of the positioning holes, thereby achieving a firm lock between the sliding column 42 and the fixed column 41. When the length needs to be adjusted, the sliding block 45 is pressed, and the sliding block 45 drives the telescopic column 43 to move radially inside the sliding column 42 and compress the spring 44, so that the outer end of the telescopic column 43 is disengaged from the positioning hole. At this time, the locking state is released, and the operator can pull or push the sliding column 42. In order to facilitate the grip and pull during high-altitude operation, an auxiliary block 46 is also fixedly connected to the outer wall of the sliding column 42.

[0026] Please refer to the following carefully. Figure 2 and Figure 3 The core structure of the adjustment mechanism 3 will be described in detail below: The adjustment mechanism 3 includes a limiting block 31 and a stud 32. The limiting block 31 is located inside the protective shell 1 and its side is in sliding contact with the side of the grinding wheel 2. The stud 32 is set perpendicular to the sliding direction of the grinding wheel 2, passes through the wall of the protective shell 1 and is threadedly connected to the limiting block 31. By rotating the stud 32 in the forward or reverse direction, the limiting block 31 can be driven to move along the axial direction of the stud 32, thereby achieving clamping and fixing or sliding release of the grinding wheel 2. This threaded clamping structure ensures that the grinding wheel 2 can be stably locked after being adjusted to any extended position, avoiding displacement during operation. Meanwhile, to provide double stability, the adjustment mechanism 3 also includes a fixing component 33, which includes a rotating column 331 and a rotating plate 332. The rotating column 331 is fixed to the protective shell 1. One end of the rotating plate 332 is rotatably connected to the protective shell 1 through the rotating column 331, and the other end is a free end. After the position of the grinding wheel 2 is adjusted and initially locked by the stud 32, the rotating plate 332 can be rotated to a specific angle so that its free end tightly abuts against the other side of the grinding wheel 2, and the rotating plate 332 is locked in this position by a nut. This abutment-type auxiliary fixing structure further enhances the reliability of limiting the grinding wheel 2 and ensures its stability under high-speed working conditions.

[0027] As a preferred embodiment of the locking method for the telescopic mechanism 4, please refer to... Figure 4 and Figure 5 In order to achieve precise and reliable segmented locking, multiple positioning holes with equal spacing are opened on the pipe wall of the fixed column 41 along its axial direction. The shape and size of the outer end of the telescopic column 43 are adapted to the positioning holes. When the outer end of the telescopic column 43 is aligned with and locked into one of the positioning holes under the elastic force of the spring 44, the locking of the sliding column 42 can be completed. By setting multiple positioning holes, the overall length of the equipment can be adjusted in multiple positions to meet the needs of different heights. As a preferred embodiment of the unlocking operation of the telescopic mechanism 4, when it is necessary to adjust the length of the equipment, the operator presses the sliding block 45 inward. The sliding block 45 will drive the telescopic column 43 to overcome the elastic force of the spring 44 and move radially inward in the sliding column 42 until its outer end is completely disengaged from the positioning hole. At this time, the lock between the sliding column 42 and the fixed column 41 is released, and the operator can freely pull or push the sliding column 42. When the required length is adjusted and the outer end of the telescopic column 43 is aligned with the next positioning hole, the sliding block 45 is released, and the telescopic column 43 will automatically reset and lock into the positioning hole under the elastic force of the spring 44, completing the new locking. As a preferred embodiment of the power supply for the equipment, the equipment also includes a wire 5. One end of the wire 5 is used to connect to an external power source, and the other end passes through the hollow interior of the fixed column 41 and the sliding column 42 in order not to affect the normal operation of the telescopic mechanism 4, and finally connects to the built-in motor that drives the grinding wheel 2 to rotate at high speed. This built-in wiring design avoids the wire 5 from being tangled or pulled on the outside, and improves the safety and convenience of operation.

[0028] The working principle is as follows: When it is necessary to clean cracks at height, the operator first presses the sliding block 45 on the telescopic mechanism 4. The sliding block 45 drives the telescopic column 43 to move radially inside the sliding column 42 and compresses the spring 44, so that the outer end of the telescopic column 43 is disengaged from the positioning hole on the fixed column 41. After unlocking, the operator holds the auxiliary block 46 to pull the sliding column 42 out of the fixed column 41 to the appropriate length, and then releases the sliding block 45. The telescopic column 43 automatically resets under the elastic force of the spring 44 and is locked into the nearest positioning hole, thereby reliably fixing the total length of the equipment to the required length, solving the problem of inconvenience in high-altitude operations caused by fixed length.

[0029] When dealing with cracks of different depths, the operator first loosens the nut used to lock the rotating plate 332, turning the rotating plate 332 away from the grinding wheel 2. Then, the operator rotates the stud 32 of the adjusting mechanism 3 in the opposite direction. The stud 32 drives the limit block 31, which is threadedly connected to it, to move, thereby releasing the clamping force on the grinding wheel 2. At this time, the grinding wheel 2 can be manually adjusted along its sliding direction to the specified height extending out of the protective shell 1. After adjustment, the operator rotates the stud 32 in the forward direction to clamp the grinding wheel 2. Then, the operator rotates the rotating plate 332 back and presses it against the other side of the grinding wheel 2 before locking it. This completes the adaptation of the cleaning depth and solves the problem of poor cleaning effect caused by the inability to adjust the depth. After all adjustments are completed, the operator connects the power supply through the wire 5, and the built-in motor drives the grinding wheel 2 to rotate at high speed, enabling efficient and safe crack cleaning operations.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
