Description

Technical Field

[0001] This invention relates to an auxiliary construction device for anti-buoyancy anchor bolts, and more particularly to a device for lowering and positioning the reinforcing bars of anti-buoyancy anchor bolts. Background Technology

[0002] In the anti-buoyancy design of underground structures, anti-buoyancy anchors are widely used due to their simple, fast, and economical construction. However, in the foundation pit engineering of large pool structures, the anti-buoyancy anchor reinforcement bars are generally quite long, making the lowering of these bars difficult.

[0003] Currently, the construction method for lowering anti-buoyancy anchor bars is as follows: lowering is achieved through a support system combined with manual lifting. This support system is a tripod structure consisting of three diagonal braces connected at the top and distributed at the bottom, providing support for the lowering of the anti-buoyancy anchor bars. This tripod structure has the following shortcomings:

[0004] 1. During construction, the support is manually moved to the hole position, the lifting rope is fixed to the steel bar, and then manually lifted and lowered. The whole process is time-consuming and labor-intensive, and the construction is inconvenient.

[0005] 2. The positioning accuracy of the anti-buoyancy anchor bars is determined by manual visual identification, which cannot guarantee the reliability of positioning. The anti-buoyancy anchor bars are easily disturbed by external factors such as wind force, and are prone to swaying and colliding with the hole wall during the lowering process, which poses a high safety risk and makes it difficult to meet the requirements of efficient and standardized construction.

[0006] 3. The tripod structure has poor stability. There may be slippage between the bottom of the tripod structure and the ground. When the anti-buoyancy anchor rod is lowered, it may shake and cause the tripod structure to shift or become unstable. In addition, the tripod structure also has the safety hazard of overturning in adverse weather conditions such as strong winds.

[0007] Therefore, there is a need for a positioning device that can assist in the stable, safe, and accurate lowering of anti-buoyancy anchor bars. Summary of the Invention

[0008] The purpose of this invention is to provide a device for positioning and lowering anti-buoyancy anchor bars, which can assist in the safe, stable, and accurate lowering of anti-buoyancy anchor bars into the hole.

[0009] This invention is implemented as follows:

[0010] A device for lowering and positioning anti-buoyancy anchor bars includes a vehicle base assembly, a support frame, a horizontal positioning assembly, a lifting assembly, a bar fixing assembly, and a fixing rod assembly. The support frame is fixedly installed on the vehicle base assembly. The horizontal positioning assembly is horizontally movable and installed on both the vehicle base assembly and the support frame. The lifting assembly is installed on the horizontal positioning assembly and moves horizontally synchronously with it. The bar fixing assembly is installed on the lifting assembly and clamps the upper end of the anti-buoyancy anchor bar. The bar fixing assembly and the anti-buoyancy anchor bar are raised and lowered synchronously via the lifting assembly. The fixing rod assembly is set on the vehicle base assembly, and the lower end of the anti-buoyancy anchor bar passes through the fixing rod assembly, so that the anti-buoyancy anchor bar is vertically positioned above the hole.

[0011] The vehicle base assembly includes a vehicle body, wheels, and an electrical control box; several pairs of wheels are symmetrically installed on both sides of the bottom of the vehicle body via axles, the electrical control box is installed in the middle of the bottom of the vehicle body, and the output end of the electrical control box is connected to the axle of the wheels; the horizontal positioning assembly and the support frame are both installed on the top of the vehicle body, and the fixing rod assembly is installed on the outer wall of the electrical control box.

[0012] The horizontal positioning component includes horizontal rails, horizontal adjustment brackets, and a first fixed bracket; a pair of horizontal rails are symmetrically installed on the vehicle body, the first fixed bracket is fixedly installed on the support frame, and a pair of horizontal rails are symmetrically installed on the first fixed bracket; the lower ends of the pair of horizontal adjustment brackets are movably connected to the vehicle body through a pair of horizontal rails, and the upper ends of the pair of horizontal adjustment brackets are movably connected to the first fixed bracket through a pair of horizontal rails; the lifting component is installed on the horizontal adjustment bracket.

[0013] The lifting assembly includes a second fixed bracket and a lifting device; the lower end of the second fixed bracket is fixedly installed in the middle of the horizontal adjustment bracket, so that the second fixed bracket is vertically positioned above the vehicle body and can move horizontally synchronously with the horizontal adjustment bracket; the lifting device is located at the upper end of the second fixed bracket, and the lifting end of the lifting device is connected to the steel bar fixing assembly.

[0014] The second fixed bracket has a pair of lifting rails symmetrically installed on both sides. The pair of lifting rails are vertically arranged, and the two ends of the steel bar fixing component are slidably connected to the pair of lifting rails.

[0015] The aforementioned rebar fixing assembly includes an upper clamping plate, a lower clamping plate, and a connecting plate. The two ends of the connecting plate are detachably connected to one end of the upper clamping plate and one end of the lower clamping plate, respectively. A pair of connecting plates are respectively connected to the two ends of the upper clamping plate and the lower clamping plate, so that an anchor bar clamping gap is formed between the upper clamping plate and the lower clamping plate. The upper end of the anti-buoyancy anchor bar is bent and inserted into the anchor bar clamping gap, and the main body of the anti-buoyancy anchor bar is in a vertical state. The pair of connecting plates are slidably connected to a pair of lifting rails.

[0016] Stabilizing arms are installed at each corner of the vehicle body. One end of the stabilizing arm can be flipped and connected to the vehicle body, while the other end of the stabilizing arm can be fixed to the ground mat.

[0017] The vehicle body is equipped with lifting lugs, with a pair of lifting lugs symmetrically arranged at both ends of the vehicle body.

[0018] The vehicle body is equipped with a positioning scanning device, which is positioned facing the anchor bolt control point.

[0019] The fixed rod assembly includes a fixed rod body, a fixed clamping part, and a movable clamping part; one end of the fixed rod body is rotatably mounted on the outer wall of the electrical control box, and the fixed clamping part is fixedly set at the other end of the fixed rod body; both the fixed clamping part and the movable clamping part are semi-circular ring structures, and the movable clamping part can be connected to the fixed clamping part to form a ring-shaped clamping part, so that the anti-buoyancy anchor rod reinforcement can pass through the clamping part.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. Because the present invention includes a vehicle base assembly and a horizontal positioning assembly, the vehicle base assembly can be moved flexibly by wheels, which facilitates the movement of the entire lowering and positioning device on the construction site and the adjustment of the lateral position of the anti-buoyancy anchor bar; the horizontal positioning assembly can adjust the longitudinal position of the anti-buoyancy anchor bar by sliding the horizontal adjustment bracket along the horizontal track, thereby aligning the anti-buoyancy anchor bar with the hole. Compared with the manual visual positioning of the prior art, the present invention can effectively improve the positioning efficiency and accuracy.

[0022] 2. Because the present invention is equipped with a lifting component, it can drive the anti-buoyancy anchor bar to rise and fall under the drive of the lifting equipment. During the lifting process, the verticality of the anti-buoyancy anchor bar is adjusted by the self-weight of the anti-buoyancy anchor bar. At the same time, it can stably and safely control the lowering of the anti-buoyancy anchor bar into the hole without the need for manual lifting and lowering, which greatly improves the construction safety and efficiency of lowering the anti-buoyancy anchor bar.

[0023] 3. Because the present invention is equipped with a steel bar fixing component and a fixing rod component, the steel bar fixing component can clamp the upper bent part of the anti-buoyancy anchor bar, so that the anti-buoyancy anchor bar hangs vertically and passes through the clamping part of the fixing rod component, thereby playing an effective limiting and guiding role for the anti-buoyancy anchor bar, ensuring that the anti-buoyancy anchor bar remains vertical during the lowering process, is not affected by external factors such as wind, avoids collision with the hole wall, and improves construction safety.

[0024] 4. The present invention has a simple structure, low weight, low cost, high structural strength, good load-bearing capacity, flexible use and movement, high recycling rate, and can clamp multiple anti-buoyancy anchor bars at the same time, which is conducive to improving the construction efficiency of anti-buoyancy anchor bars and is suitable for anti-buoyancy construction of various underground structures.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Please see the appendix Figure 1 A device for lowering and positioning anti-buoyancy anchor bars includes a vehicle base assembly, a support frame 2, a horizontal positioning assembly, a lifting assembly, a bar fixing assembly, and a fixing rod assembly. The support frame 2 is fixedly installed on the vehicle base assembly. The horizontal positioning assembly is horizontally movable and installed on the vehicle base assembly and the support frame 2. The lifting assembly is installed on the horizontal positioning assembly and moves horizontally synchronously with it. The bar fixing assembly is installed on the lifting assembly and clamps the upper end of the anti-buoyancy anchor bar 4. The bar fixing assembly and the anti-buoyancy anchor bar 4 are raised and lowered synchronously through the lifting assembly. The fixing rod assembly is set on the vehicle base assembly, and the lower end of the anti-buoyancy anchor bar 4 passes through the fixing rod assembly, so that the anti-buoyancy anchor bar 4 is vertically positioned above the hole.

[0033] The anti-buoyancy anchor rod 4 and the fixing rod assembly are clamped and limited to a vertical position by the anchor rod fixing assembly. The horizontal position of the anti-buoyancy anchor rod 4 can be adjusted by the vehicle base assembly and the horizontal positioning assembly to achieve alignment between the anti-buoyancy anchor rod 4 and the hole. After the horizontal position is adjusted to the correct position, the anti-buoyancy anchor rod 4 is lowered vertically into the hole by the lifting assembly, achieving a safe, stable, and precise lowering of the anti-buoyancy anchor rod 4.

[0034] Please see the appendix Figure 1 The vehicle base assembly includes a vehicle body 11, wheels 12, and an electrical control box 13; several pairs of wheels 12 are symmetrically installed on both sides of the bottom of the vehicle body 11 via axles, and the electrical control box 13 is installed in the middle of the bottom of the vehicle body 11. The output end of the electrical control box 13 is connected to the axle of the wheels 12; the horizontal positioning assembly and the support frame 2 are both installed on the top of the vehicle body 11, and the fixing rod assembly is installed on the outer wall of the electrical control box 13.

[0035] The wheels 12 can be swivel wheels with brake plates, facilitating the movement of the vehicle body 11 on the construction site. This allows the vehicle body 11 to be moved to the work area and positioned for lowering the anti-buoyancy anchor rod 4, facilitating the lowering operation. The fixing rod assembly is located on the front outer wall of the electrical control box 13, allowing it to work in conjunction with the rebar fixing assembly to secure the anti-buoyancy anchor rod 4.

[0036] The electrical control box 13 can be equipped with computer equipment or PLC equipment, with a built-in motor and battery. The battery provides power to the motor, which can also be powered by an external power source. The motor's output shaft is connected to the axle of the wheel 12 to drive its movement. An existing automatic power-off locking device can be installed inside the electrical control box to lock the motor's output shaft in case of insufficient power or a sudden power outage, thereby locking the wheel 12 and preventing accidental slippage of the vehicle body 11. This ensures the safety and functionality of the entire lowering and positioning device. A remote control receiver can be configured inside the electrical control box 13, allowing construction personnel to remotely control the movement of the vehicle body 11.

[0037] Please see the appendix Figure 2 The horizontal positioning component includes a horizontal rail 51, a horizontal adjustment bracket 52, and a first fixed bracket 53; a pair of horizontal rails 51 are symmetrically installed on the vehicle body 11, and the first fixed bracket 53 is fixedly installed on the support frame 2, with a pair of horizontal rails 51 symmetrically installed on the first fixed bracket 53; the lower ends of the pair of horizontal adjustment brackets 52 are movably connected to the vehicle body 11 via a pair of horizontal rails 51 through sliders, and the upper ends of the pair of horizontal adjustment brackets 52 are movably connected to the first fixed bracket 53 via a pair of horizontal rails 51 through sliders; a lifting component is installed on the horizontal adjustment bracket 52.

[0038] Preferably, the horizontal adjustment bracket 52 and the first fixed bracket 53 can be made of welded steel pipes, and the pair of horizontal rails 51 can be made of channel steel. One end of the slider is embedded in the channel steel, and the other end of the slider is connected to the horizontal adjustment bracket 52. The pair of horizontal adjustment brackets 52 are vertically arranged and slide along the upper and lower pairs of horizontal rails 51 via sliders to adjust the horizontal position of the anti-buoyancy anchor rod 4 back and forth, so that it can be accurately positioned for lowering. The first fixed bracket 53 is a C-shaped structure with one end open to avoid collision between the anti-buoyancy anchor rod 4 and the first fixed bracket 53 when adjusting the horizontal position.

[0039] Please see the appendix Figure 3 The lifting assembly includes a second fixed bracket 61 and a lifting device 62; the lower end of the second fixed bracket 61 is fixedly installed in the middle of the horizontal adjustment bracket 52, so that the second fixed bracket 61 is vertically set above the vehicle body 11 and can move horizontally synchronously with the horizontal adjustment bracket 52; the lifting device 62 is set at the upper end of the second fixed bracket 61, and the lifting end of the lifting device 62 is connected to the steel bar fixing assembly.

[0040] Preferably, the lifting device 62 can be a winch, electric hoist, or other lifting equipment. The lifting end of the winch or electric hoist is connected to the steel bar fixing component via a wire rope, thereby driving the steel bar fixing component to rise and fall. The method of lifting or lowering objects using a winch or electric hoist via a wire rope is existing technology and will not be described in detail here. Driven by the lifting device 62, the steel bar fixing component moves up and down relative to the second fixed support 61, thereby driving the anti-buoyancy anchor steel bar 4 to rise and fall stably and safely.

[0041] The second fixed support 61 can be made of welded steel pipe and fixed to the middle of the horizontal adjustment support 52 by welding the mounting plate. The height of the second fixed support 61 can be determined according to the length of the anti-buoyancy anchor bar 4 and its lowering distance, preferably not less than 10 meters.

[0042] Please see the appendix Figure 3 The second fixed bracket 61 has a pair of lifting rails 63 symmetrically installed on both sides. The pair of lifting rails 63 are vertically arranged, and the two ends of the steel bar fixing component are slidably connected to the pair of lifting rails 63 by sliders.

[0043] One end of the slider is embedded in the lifting rail 63, and the other end of the slider is connected to the end of the rebar fixing component. The pair of lifting rails 63 and slider are used to guide and limit the lifting of the rebar fixing component, which helps to control the lifting trajectory of the rebar fixing component, ensure the lifting stability of the rebar fixing component, and thus ensure the safe, stable and accurate lowering of the anti-buoyancy anchor rebar 4.

[0044] Please see the appendix Figure 4The steel bar fixing assembly includes an upper clamping plate 71, a lower clamping plate 72, and a connecting plate 73. The two ends of the connecting plate 73 are detachably connected to one end of the upper clamping plate 71 and one end of the lower clamping plate 72, respectively. A pair of connecting plates 73 are respectively connected to the two ends of the upper clamping plate 71 and the lower clamping plate 72, so that an anchor bar clamping gap is formed between the upper clamping plate 71 and the lower clamping plate 72. The upper end of the anti-buoyancy anchor bar 4 is bent and inserted into the anchor bar clamping gap, and the main body of the anti-buoyancy anchor bar 4 is in a vertical state. The pair of connecting plates 73 are slidably connected to a pair of lifting rails 63 by sliders.

[0045] The upper bent portion of the anti-buoyancy anchor bar 4 is inserted through the clamping gap between the upper clamping plate 71 and the lower clamping plate 72. The height of the clamping gap can be adjusted according to actual needs. After adjustment, it is fixed and limited by bolts through a pair of connecting plates 73, thereby ensuring that the upper clamping plate 71 and the lower clamping plate 72 stably clamp the upper end of the anti-buoyancy anchor bar 4. The bent portion at the upper end of the anti-buoyancy anchor bar 4 facilitates clamping by the upper clamping plate 71 and the lower clamping plate 72, so that the main body of the anti-buoyancy anchor bar 4 hangs down under the action of gravity and remains in a vertical state, which facilitates precise lowering.

[0046] Preferably, the lengths of the upper clamping plate 71 and the lower clamping plate 72 can be determined according to the specifications and quantity of the anti-buoyancy anchor rods 4, and the upper clamping plate 71 and the lower clamping plate 72 can clamp multiple anti-buoyancy anchor rods 4 at the same time.

[0047] The support frame 2 has a C-shaped opening on one side, forming a three-sided surround arrangement. The anti-buoyancy anchor rod 4 is located at the opening of the support frame 2, and the anti-buoyancy anchor rod 4 can move horizontally towards or away from the opening of the support frame 2 via a horizontal positioning component. The support frame 2 has high stability and load-bearing capacity, providing reliable support and ensuring the stability of the anti-buoyancy anchor rod 4 during adjustment, positioning, and lowering.

[0048] Please see the appendix Figure 1 Stabilizing arms 14 are installed at each corner of the vehicle body 11. One end of the stabilizing arm 14 is rotatably connected to the vehicle body 11 via a pivot, and the other end of the stabilizing arm 14 can be fixed to the ground mat layer by expansion bolts.

[0049] The length and number of stabilizing arms 14 can be adjusted according to actual needs. By fixing the stabilizing arms 14 to the ground cushion layer, the stability of the vehicle body 11 can be improved, preventing the vehicle body 11 from overturning. This ensures stability when the anti-buoyancy anchor bar 4 is lowered, avoiding collision with the hole wall.

[0050] Please see the appendix Figure 1 The vehicle body 11 is equipped with lifting lugs 15, and a pair of lifting lugs 15 are symmetrically arranged at both ends of the vehicle body 11.

[0051] Preferably, a pair of lifting lugs 15 can be provided, and lifting holes are opened on the lifting lugs 15 to facilitate the hoisting of the entire lowering and positioning device to the working surface by lifting equipment such as tower cranes. Since the excavation depth of the foundation pit on site is large, hoisting can avoid the complex ground environment of the construction site affecting the self-movement of the vehicle body 11.

[0052] Please see the appendix Figure 1 The vehicle body 11 is equipped with a positioning scanning device 16, which is set facing the anchor bolt control point.

[0053] Preferably, the positioning scanning device 16 can be installed on the top of the vehicle body 11 for positioning and centering with the anchor control points marked on the operating surface, thereby further ensuring the positioning accuracy of the anti-buoyancy anchor reinforcement.

[0054] Please see the appendix Figure 5 The fixed rod assembly includes a fixed rod body 31, a fixed clamping part 32, and a movable clamping part 33. One end of the fixed rod body 31 is rotatably mounted on the outer wall of the electrical control box 13 via a rotating shaft, and the fixed clamping part 32 is fixedly disposed at the other end of the fixed rod body 31. Both the fixed clamping part 32 and the movable clamping part 33 have a semi-circular structure. The movable clamping part 33 can be connected to the fixed clamping part 32 to form a circular clamping part, so that the anti-buoyancy anchor rod 4 can pass through the clamping part.

[0055] When adjusting the position of the anti-buoyancy anchor bar 4, the fixing rod body 31 can be folded towards the electrical control box 13 to avoid collision and damage to the anti-buoyancy anchor bar 4. When the anti-buoyancy anchor bar 4 is adjusted to the correct position, the fixing rod body 31 is flipped open via a pivot, so that the anti-buoyancy anchor bar 4 is located inside the fixed clamping part 32. The movable clamping part 33 is then installed so that the clamping part can match and clamp the anti-buoyancy anchor bar 4 to ensure its stability. The radii of the fixed clamping part 32 and the movable clamping part 33 can be adjusted according to the diameter of the anti-buoyancy anchor bar 4, so that the inner diameter of the clamping part is slightly larger than the diameter of the anti-buoyancy anchor bar 4, which serves to limit and guide, preventing the anti-buoyancy anchor bar 4 from shaking or tilting.

[0056] Please see the appendix Figure 1 To be continued Figure 5 The method of use and working principle of this invention are as follows:

[0057] The entire lowering and positioning device is hoisted to the work area and roughly aligned with the hole by connecting it to the lifting lug 15 via a tower crane, and then disconnected from the tower crane.

[0058] The upper end of the anti-buoyancy anchor bar 4 is bent and the bent part is clamped by the upper clamping plate 71 and the lower clamping plate 72. The connecting plate 73 is bolted to both ends of the upper clamping plate 71 and the lower clamping plate 72 to ensure reliable clamping of the anti-buoyancy anchor bar 4.

[0059] Based on the location of the hole, the wheel 12 is controlled to roll via the electrical control box 13, adjusting the lateral position of the anti-buoyancy anchor bar 4 so that it moves directly above the hole. Then, the longitudinal position of the anti-buoyancy anchor bar 4 is adjusted by sliding the horizontal adjustment bracket 52 horizontally along the two pairs of horizontal rails 51, ensuring precise alignment between the anti-buoyancy anchor bar 4 and the hole, thus improving the positioning accuracy of the anti-buoyancy anchor bar 4. The stabilizing arm 14 is then rotated downwards onto the ground surface via a rotating shaft and locked with expansion bolts to prevent accidental movement of the vehicle body 11.

[0060] The lifting device 62 drives the steel bar fixing assembly and the anti-buoyancy anchor bar 4 to rise and fall, so that the anti-buoyancy anchor bar 4 is in a vertical state. Then, the fixing rod assembly is flipped outward by rotating the shaft and opened. The movable clamping part 33 is installed on the fixed clamping part 32 by bolts to form a ring-shaped clamping part. The lower end of the anti-buoyancy anchor bar 4 is adjusted to pass through the clamping part to ensure the verticality of the anti-buoyancy anchor bar 4.

[0061] Finally, the lifting device 62 drives the steel bar fixing assembly and the anti-buoyancy anchor bar 4 to be lowered into the hole along the lifting track 63. Under the drive of the lifting device 62, the lowering process of the anti-buoyancy anchor bar 4 is safe and stable, and the verticality of the anti-buoyancy anchor bar 4 is ensured when it is lowered by the clamping and limiting of the steel bar fixing assembly and the fixing rod assembly, so as to avoid shaking or collision with the hole wall by external force.

[0062] After the anti-buoyancy anchor bar 4 is lowered into place, subsequent grouting and other work will be carried out. The subsequent work on the anti-buoyancy anchor bar 4 can be carried out using existing processes, which will not be elaborated here.

[0063] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
