Description

Technical Field

[0001] This utility model relates to the field of anti-seepage wall technology, specifically to an anti-seepage wall slot hole tilt correction device. Background Technology

[0002] In the field of concrete construction technology for cutoff walls or diaphragm walls, cutoff walls are a key seepage prevention system in water conservancy and hydropower projects, dikes, and dam foundations. The construction quality of these walls directly determines the safety, stability, and long-term durability of the entire structure. In such projects, cutoff walls are usually constructed using the trench method, which involves drilling narrow trenches using equipment such as impact drills, grab buckets, or trench milling machines, and then pouring concrete into the trenches to form a continuous cutoff wall. However, during the trench drilling process, the problem of hole inclination frequently occurs due to factors such as uneven strata, the natural sway of the drill bit itself under its own weight and impact. Hole inclination not only leads to uneven joints, forks, or misalignments in the trenches, damaging the continuity and seepage prevention effect of the cutoff wall, but may also prevent the trenches from reaching the designed embedment depth, weakening the wall's load-bearing capacity. Therefore, a special hole inclination correction device is needed to control the verticality of the trenches.

[0003] Existing devices for correcting the deviation of trench holes in anti-seepage walls have significant shortcomings: Firstly, the mounting frames of existing devices are mostly fixed-width structures without adjustable width components. When the trench width changes during construction, the fixed-width mounting frames cannot accommodate different trench sizes, requiring workers to replace the correction device with one of the appropriate width. This not only increases the procurement cost of construction equipment but also prolongs the preparation period and reduces overall construction efficiency due to the time-consuming replacement process. Secondly, the limiting structures of existing devices mostly use rigid guides that contact the drill string's wire rope without friction-reducing components. The wire rope experiences significant sliding friction as it moves within the guides, which over time leads to wear and shortens its lifespan. Excessive friction also causes instability in the drill string's operation, affecting the accuracy and effectiveness of the deviation correction and failing to meet the stringent requirements for trench verticality. Therefore, a new device for correcting the deviation of trench holes in anti-seepage walls is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for correcting the misalignment of grooves in anti-seepage walls. This solves the technical problem that the fixed-width mounting brackets cannot be adapted to grooves of different specifications, requiring construction workers to replace the device with one of the corresponding width before continuing operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for correcting the deviation of groove holes in a seepage-proof wall, comprising:

[0006] The mounting bracket and the limiting structure set on the upper surface of the mounting bracket are provided. The lower surface of the mounting bracket is equipped with casters around its perimeter, and telescopic rods are added to both sides of the upper part of the inner cavity of the mounting bracket. The limiting structure includes a limiting rod, and a bearing is installed on the outer surface of the limiting rod. The upper surface of the mounting bracket is evenly provided with first connecting holes at the front and rear ends, and the lower surface of the limiting rod is evenly provided with second connecting holes. The shape and size of the first connecting holes and the second connecting holes correspond to each other.

[0007] The installation frame is moved to the corresponding construction position of the anti-seepage wall groove by using the casters;

[0008] The width of the mounting frame is adjusted by using a telescopic rod to fit the slot being constructed.

[0009] The limiting structure is installed on the upper surface of the mounting bracket by matching the first connecting hole on the upper surface of the mounting bracket with the second connecting hole on the lower surface of the limiting rod.

[0010] The wire rope of the drilling tool passes through the bearing, and the bearing rotates as the wire rope moves, thus constraining the direction of the wire rope's movement.

[0011] When the slot hole is misaligned, first disassemble the limiting structure, then realign the first connecting hole and the second connecting hole to move the limiting structure to a position opposite to the misalignment direction, and then reinstall the limiting structure on the upper surface of the mounting bracket to correct the misalignment of the slot hole.

[0012] Preferably, the telescopic rod comprises a hollow column and a telescopic column, and the telescopic column and the hollow column are slidably connected. Through the sliding engagement of the telescopic column and the hollow column, the overall length of the telescopic rod can be flexibly adjusted, adapting to the length requirements of the telescopic rod in different scenarios, thus improving the applicability and flexibility of the telescopic rod.

[0013] Preferably, the upper surface of the hollow column is uniformly provided with limiting holes, and the center positions of both sides of the inner wall of the hollow column are provided with positioning grooves. The uniformly distributed limiting holes on the hollow column can realize the length limitation of the telescopic rod at multiple positions to meet the fixed requirements of different lengths; the positioning grooves on both sides of the inner wall can guide the subsequent sliding structure, avoid deviation during sliding, and ensure the stability and accuracy of the telescopic rod during adjustment.

[0014] Preferably, an outer connecting plate is added to the outer end of the telescopic column, and a screw is installed at the center of the back side of the outer connecting plate, with the screw threadedly connected to the center of the inner cavity of the telescopic column. Utilizing the self-locking characteristic of the threaded connection, rotating the screw can precisely control the position of the outer connecting plate, ensuring the positional accuracy of the outer connecting plate when connected to external components; at the same time, the threaded connection is stable and reliable, effectively maintaining the adjusted position of the outer connecting plate, preventing loosening during use, and improving connection stability.

[0015] Preferably, a slider is installed at the inner end of the telescopic column, and the surface of the slider is slidably fitted against the inner wall of the hollow column. Positioning blocks are installed at the center of both sides of the slider, and these positioning blocks are slidably fitted against their corresponding positioning grooves. The sliding fit between the slider and the inner wall of the hollow column increases the contact area, improving the stability of the telescopic column during sliding and preventing it from wobbling. The sliding cooperation between the positioning blocks and the positioning grooves further limits the sliding direction of the slider, preventing it from rotating or shifting during sliding and ensuring that the telescopic column is always stably adjusted along a preset direction.

[0016] Preferably, a limiting post is inserted and connected to the center of the upper surface of the slider, and a compression spring is added between the bottom end of the limiting post and the inner cavity of the slider. The top end of the limiting post corresponds to the shape and position of the limiting hole. The compression spring can realize the automatic reset of the limiting post without manual operation, simplifying the operation steps of fixing the length of the telescopic rod and improving the convenience of use. The corresponding insertion of the limiting post and the limiting hole can quickly fix the position of the telescopic post, and the fixing method is simple and reliable, which facilitates quick switching of the length of the telescopic rod to meet different usage needs.

[0017] Preferably, guide cylinders are added to both sides of the lower part of the inner cavity of the mounting bracket, and guide rods are slidably connected to the inner cavities of the guide cylinders. The guide rods are designed with radii at both ends greater than the center radius. The guide cylinders provide a stable sliding guide path for the guide rods, ensuring accurate sliding direction and preventing deviation. The design of the guide rods with radii at both ends greater than the center radius effectively prevents the guide rods from detaching from the inner cavity of the guide cylinders during sliding, avoiding component detachment and improving the safety and stability of the structure.

[0018] Preferably, a return spring is sleeved at the center of the guide cylinder, and both ends of the return spring are respectively in contact with the inner end of the guide rod and the inner wall of the guide cylinder. The return spring enables the guide rod to automatically return to its original position without manual operation, simplifying the operation process and improving ease of use; at the same time, the elasticity of the return spring can buffer the impact force when the guide rod slides, reduce the collision and wear between the guide rod and the guide cylinder, and extend the service life of the components.

[0019] Preferably, the mounting bracket has studs threadedly connected to both the front and rear ends, with an external connecting handle mounted on the top of the stud and a plug-in pin rotatably connected to the bottom of the stud. The external connecting handle increases the contact area for hand operation, making it easier to rotate the stud with less effort and reducing the difficulty of operation; the threaded connection allows for precise adjustment of the vertical position of the plug-in pin, and the threaded connection is self-locking, ensuring that the position of the plug-in pin is stable after adjustment and preventing it from moving on its own; the rotatable connection between the plug-in pin and the stud prevents the plug-in pin from affecting subsequent insertion and mating due to rotation of the stud, ensuring the functionality of the plug-in pin.

[0020] Preferably, the outer surface of the caster wheel is uniformly provided with insertion grooves, and the insertion grooves are connected to the corresponding insertion posts. The insertion connection between the insertion posts and the insertion grooves can quickly achieve braking and fixing of the caster wheel, preventing the caster wheel from rolling on its own when no movement is needed, and improving the stability of the overall structure; the uniformly provided insertion grooves on the outer surface of the caster wheel ensure that the insertion posts can find the corresponding insertion positions when the caster wheel is at any rotation angle, achieving all-round braking and improving the flexibility and reliability of braking.

[0021] Compared with the prior art, this utility model provides a device for correcting the deviation of groove holes in an anti-seepage wall, which has the following beneficial effects:

[0022] The anti-seepage wall trench hole tilt correction device has telescopic rods on both sides of the upper part of the inner cavity of the mounting frame. The width of the mounting frame can be flexibly adjusted by extending and retracting the telescopic rods, so that the device can be adapted to anti-seepage wall trench holes of different widths and specifications. There is no need to replace the entire device due to changes in trench hole width, which effectively improves the versatility of the device and reduces construction costs and preparation time.

[0023] The outer surface of the limit rod is equipped with a bearing. When the wire rope of the drill bit is working, it comes into contact with the bearing. The rolling characteristics of the bearing can reduce the friction between the wire rope and the limit structure, reduce the wear of the wire rope, extend the service life of the wire rope, and at the same time ensure the stability of the drill bit's operation, indirectly improving the hole deviation correction effect.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides a technical solution: a device for correcting the tilt of grooves in a seepage-proof wall, comprising: (see details below) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The mounting frame 1 and the limiting structure 2 are provided on the upper surface of the mounting frame 1. The lower surface of the mounting frame 1 is equipped with casters 3 around its perimeter. Telescopic rods 4 are provided on both sides of the upper part of the inner cavity of the mounting frame 1. The limiting structure 2 includes a limiting rod 5. A bearing 6 is installed on the outer surface of the limiting rod 5. The upper surface of the mounting frame 1 is evenly provided with first connecting holes at the front and rear ends. The lower surface of the limiting rod 5 is evenly provided with second connecting holes. The shape and size of the first connecting holes and the second connecting holes correspond to each other.

[0033] The universal wheels 3 drive the mounting frame 1 to the corresponding construction position of the anti-seepage wall groove;

[0034] The width of the mounting frame 1 is adjusted by the telescopic rod 4 so that the mounting frame 1 can fit the groove hole being constructed.

[0035] By matching the first connecting hole on the upper surface of the mounting bracket 1 with the second connecting hole on the lower surface of the limiting rod 5, the limiting structure 2 is installed on the upper surface of the mounting bracket 1.

[0036] The wire rope of the drilling tool passes through the bearing 6, and the bearing 6 rotates as the wire rope moves, thus constraining the direction of the wire rope's movement.

[0037] When the slot hole is skewed, first remove the limiting structure 2, then realign the first connecting hole and the second connecting hole, and move the limiting structure 2 to a position opposite to the skewed direction. Then reinstall the limiting structure 2 on the upper surface of the mounting bracket 1 to correct the skewed slot hole.

[0038] The casters 3 on the lower surface of the mounting frame 1 can move the mounting frame 1 freely, allowing the installation position of the device to be adjusted without relying on external handling equipment, which greatly reduces the difficulty of relocation on the construction site and improves construction efficiency.

[0039] The telescopic rod 4 at the upper part of the inner cavity of the mounting frame 1 can drive the mounting frame 1 to adjust its width, which can adapt to the anti-seepage wall grooves of different widths and specifications, avoiding the problem of having to replace different correction devices due to differences in groove size, and reducing equipment investment costs.

[0040] With the help of the corresponding engagement of the first connecting hole of the mounting bracket 1 and the second connecting hole of the limiting rod 5, the limiting structure 2 can be easily disassembled and its position adjusted. For the hole tilt in different directions, the limiting structure 2 can be moved to the opposite direction to complete the correction without complicated operation. This effectively avoids problems such as uneven joints of the slots and holes and weakened load-bearing capacity, ensuring the continuity and seepage prevention effect of the anti-seepage wall.

[0041] The bearing 6 on the outer surface of the limit rod 5 rotates as the wire rope moves, converting the sliding friction between the wire rope and the limit structure 2 into rolling friction, which greatly reduces the wear of the wire rope and the limit rod 5. At the same time, the structural design of the bearing 6 can also reduce its own wear and extend the overall service life of the device.

[0042] The limiting structure 2 can be detachably installed on the mounting bracket 1 through the first connecting hole and the second connecting hole. When the limiting rod 5 or the bearing 6 is damaged, the limiting structure 2 can be disassembled separately for maintenance or replacement without the need for the entire device to be scrapped, thus reducing maintenance costs.

[0043] Please see Figure 3 The telescopic rod 4 comprises a hollow column 7 and a telescopic column 9, which are slidably connected. The telescopic column 9 slides relative to the hollow column 7. Through the sliding connection between the telescopic column 9 and the hollow column 7, the length of the telescopic rod 4 can be changed, thereby adjusting the width of the mounting bracket 1. Through the sliding cooperation between the telescopic column 9 and the hollow column 7, the overall length of the telescopic rod 4 can be flexibly adjusted, adapting to the usage requirements of the telescopic rod 4 in different scenarios, thus improving the applicability and flexibility of the telescopic rod 4.

[0044] The upper surface of the hollow column 7 is uniformly provided with limiting holes 8, and the center positions of the two sides of the inner wall of the hollow column 7 are provided with positioning grooves 13. The limiting holes 8 provide the insertion and positioning positions for the subsequent limiting structure 2, and the positioning grooves 13 provide the sliding guide path for the subsequent positioning structure, providing the basic conditions for the length adjustment and stable sliding of the telescopic rod 4; the evenly distributed limiting holes 8 on the hollow column 7 can realize the length limiting of the telescopic rod 4 at multiple positions to meet the fixed requirements of different lengths; the positioning grooves 13 on both sides of the inner wall can guide the subsequent sliding structure, avoid deviation during sliding, and ensure the stability and accuracy of the telescopic rod 4 during adjustment.

[0045] An outer connecting plate 10 is added to the outer end of the telescopic column 9, and a screw 11 is installed at the center of the back side of the outer connecting plate 10, with the screw 11 threadedly connected to the center of the inner cavity of the telescopic column 9. Rotating the outer connecting plate 10, through the threaded connection between the screw 11 and the center of the inner cavity of the telescopic column 9, allows the outer connecting plate 10 to move closer to or further away from the telescopic column 9 in a linear motion, thereby adjusting the position of the outer connecting plate 10. Utilizing the self-locking characteristic of the threaded connection, rotating the screw 11 can precisely control the position of the outer connecting plate 10, ensuring the positional accuracy of the outer connecting plate 10 when connected to external components. At the same time, the threaded connection is stable and reliable, effectively maintaining the adjusted position of the outer connecting plate 10, preventing loosening during use, and improving connection stability.

[0046] Please see Figure 4 A slider 12 is installed at the inner end of the telescopic column 9, and the surface of the slider 12 slides against the inner wall of the hollow column 7. Positioning blocks 14 are installed at the center of both sides of the slider 12, and the positioning blocks 14 slide against the corresponding positioning grooves 13. The telescopic column 9 drives the slider 12 to slide relative to the inner wall of the hollow column 7, while the slider 12 drives the positioning blocks 14 to slide within the corresponding positioning grooves 13, simultaneously achieving length adjustment and directional limitation of the telescopic column 9. The sliding contact between the slider 12 and the inner wall of the hollow column 7 increases the contact area, improving the stability of the telescopic column 9 during sliding and preventing it from shaking. The sliding cooperation between the positioning blocks 14 and the positioning grooves 13 further limits the sliding direction of the slider 12, preventing the slider 12 from rotating or shifting during sliding, ensuring that the telescopic column 9 is always stably adjusted along the preset direction.

[0047] A limiting post 15 is inserted and connected to the center of the upper surface of the slider 12, and a compression spring 16 is added between the bottom end of the limiting post 15 and the inner cavity of the slider 12. The top end of the limiting post 15 corresponds to the shape and position of the limiting hole 8. When the limiting post 15 is pressed, the limiting post 15 compresses the compression spring 16 and slides downward relative to the inner cavity of the slider 12, causing the top end of the limiting post 15 to disengage from the limiting hole 8. When the limiting post 15 is released, the compression spring 16 returns to its original shape, causing the limiting post 15 to slide upward relative to the inner cavity of the slider 12, so that the top end of the limiting post 15 inserts into the corresponding limiting hole 8. The compression spring 16 can realize the automatic reset of the limiting post 15 without manual operation, simplifying the operation steps of fixing the length of the telescopic rod 4 and improving the convenience of use. The corresponding insertion of the limiting post 15 and the limiting hole 8 can quickly fix the position of the telescopic rod 9, and the fixing method is simple and reliable, which facilitates quick switching of the length of the telescopic rod 4 to meet different usage needs.

[0048] Please see Figure 5 The mounting bracket 1 has guide cylinders 17 installed on both sides of the lower part of its inner cavity, and guide rods 18 are slidably connected to the inner cavity of the guide cylinders 17. The guide rods 18 are designed with radii at both ends greater than the center radius. The guide rods 18 slide relative to the inner cavity of the guide cylinders 17. The guide cylinders 17 guide the guide rods 18, limiting the sliding direction of the guide rods 18. The guide cylinders 17 provide a stable sliding guide path for the guide rods 18, ensuring the accuracy of the sliding direction of the guide rods 18 and avoiding deviation. The design of the guide rods 18 with radii at both ends greater than the center radius effectively prevents the guide rods 18 from detaching from the inner cavity of the guide cylinders 17 during sliding, avoiding component detachment and improving the safety and stability of the structure.

[0049] A return spring 19 is fitted at the center of the guide cylinder 17, with its two ends respectively fitting against the inner end of the guide rod 18 and the inner wall of the guide cylinder 17. When the guide rod 18 slides relative to the guide cylinder 17, the inner end of the guide rod 18 presses against or releases the return spring 19, causing the return spring 19 to deform. When the external force is removed, the return spring 19 returns to its original deformation, causing the guide rod 18 to slide in the opposite direction relative to the guide cylinder 17, returning to its initial position. The return spring 19 enables the guide rod 18 to automatically reset, eliminating the need for manual operation, simplifying the operation process, and improving ease of use. At the same time, the elasticity of the return spring 19 can buffer the impact force when the guide rod 18 slides, reducing the collision and wear between the guide rod 18 and the guide cylinder 17, and extending the service life of the components.

[0050] Please see Figure 6The mounting bracket 1 has studs 20 threadedly connected to both its front and rear ends. An external connecting handle 21 is mounted on the top of each stud 20, and a plug-in pin 22 is rotatably connected to the bottom of the stud 20. Rotating the external connecting handle 21 causes the stud 20 to rotate relative to the mounting bracket 1. Through the threaded connection between the stud 20 and the mounting bracket 1, the plug-in pin 22 moves vertically up and down. The external connecting handle 21 increases the contact area for hand operation, making it easier and less strenuous to rotate the stud 20, thus reducing operational difficulty. The threaded connection allows for precise adjustment of the vertical position of the plug-in pin 22, and its self-locking property ensures the stability of the plug-in pin 22 after adjustment, preventing it from moving on its own. The rotatable connection between the plug-in pin 22 and the stud 20 prevents the plug-in pin 22 from affecting subsequent insertion and ensures its functionality.

[0051] The outer surface of the caster wheel 3 is uniformly provided with insertion slots 23, and the insertion slots 23 are inserted into the corresponding insertion posts 22. When the insertion post 22 moves downward in a straight line, the insertion post 22 inserts into the corresponding insertion slot 23 on the outer surface of the caster wheel 3; when the insertion post 22 moves upward in a straight line, the insertion post 22 disengages from the corresponding insertion slot 23 on the outer surface of the caster wheel 3. The insertion connection between the insertion post 22 and the insertion slot 23 can quickly achieve braking and fixing of the caster wheel 3, preventing the caster wheel 3 from rolling on its own when it does not need to move, and improving the stability of the overall structure. The uniformly provided insertion slots 23 on the outer surface of the caster wheel 3 ensure that the insertion post 22 can find the corresponding insertion position when the caster wheel 3 is at any rotation angle, realizing all-round braking and improving the flexibility and reliability of braking.

[0052] In this scheme: the caster wheel 3 drives the mounting frame 1 to move to the corresponding construction position of the anti-seepage wall groove; rotate the outer connecting handle 21, the outer connecting handle 21 drives the stud 20 to rotate relative to the mounting frame 1, the stud 20 drives the plug-in post 22 to move downward in a straight line, and the plug-in post 22 is inserted into the corresponding plug-in groove 23 on the outer surface of the caster wheel 3.

[0053] Pressing the limiting post 15 compresses the compression spring 16 and slides downward relative to the inner cavity of the slider 12. The top of the limiting post 15 disengages from the limiting hole 8 on the hollow column 7. The telescopic post 9 drives the slider 12 to slide relative to the inner wall of the hollow column 7. The slider 12 drives the positioning block 14 to slide in the positioning groove 13 on the inner wall of the hollow column 7. At the same time, the guide rod 18 slides relative to the inner cavity of the guide cylinder 17. The inner end of the guide rod 18 compresses or releases the reset spring 19. The reset spring 19 deforms, and the telescopic rod 4 drives the mounting bracket 1 to adjust its width. Releasing the limiting post 15 restores the deformation of the compression spring 16. The compression spring 16 drives the limiting post 15 to slide upward relative to the inner cavity of the slider 12. The top of the limiting post 15 inserts into the corresponding limiting hole 8 on the hollow column 7. When the external force is removed, the reset spring 19 restores its deformation. The reset spring 19 drives the guide rod 18 to slide in the opposite direction relative to the guide cylinder 17, returning to the initial position.

[0054] By matching the first connecting hole on the upper surface of the mounting frame 1 with the second connecting hole on the lower surface of the limiting rod 5, the limiting structure 2 is installed on the upper surface of the mounting frame 1; the wire rope of the drill bit passes through the bearing 6, and the bearing 6 rotates as the wire rope moves, thus constraining the direction of movement of the wire rope.

[0055] When the slot hole is skewed, first disassemble the limiting structure 2, then realign the first connecting hole and the second connecting hole to move the limiting structure 2 to a position opposite to the skewed direction, and then reinstall the limiting structure 2 on the upper surface of the mounting bracket 1; if it is necessary to adjust the position of the outer connecting plate 10, rotate the outer connecting plate 10, and through the threaded connection between the screw 11 and the center of the inner cavity of the telescopic column 9, the outer connecting plate 10 moves closer to or further away from the telescopic column 9 in a straight line.

[0056] If the limit rod 5 or bearing 6 is damaged, disassemble the limit structure 2 for maintenance or replacement; when the mounting bracket 1 needs to be moved again, rotate the outer connecting handle 21, the outer connecting handle 21 drives the stud 20 to rotate relative to the mounting bracket 1, the stud 20 drives the plug-in post 22 to move upward in a straight line, the plug-in post 22 disengages from the corresponding plug-in groove 23 on the outer surface of the universal wheel 3, and the universal wheel 3 drives the mounting bracket 1 to move freely.
