Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a calibrating device for cast-in-place piles. Background Technology

[0002] Cast-in-place piles are a common construction technique for foundation engineering. They refer to piles formed in the foundation soil by mechanical drilling, steel pipe extrusion, or manual excavation, followed by the placement of a steel cage in the pile hole and the pouring of concrete. Cast-in-place pile calibration devices are equipment used to calibrate and control the position, verticality, diameter, and parameters of the pile during the construction process to ensure that the cast-in-place piles meet the design requirements and construction specifications.

[0003] A search revealed Chinese Patent Publication No. CN217480140U, which discloses a calibration device for a post-insertion reinforced concrete pile. The device includes a main body, a retrieval mechanism, and a calibration mechanism. The retrieval mechanism is located above the main body, and the calibration mechanism is located below it. The main body includes a fixed plate, a threaded mounting hole, a limiting plate, a placement groove, and a limiting ring. The threaded mounting hole is fixedly disposed on the upper end of the fixed plate, and the limiting plate is fixedly disposed in the middle of the upper end of the fixed plate. The fixed plate is perforated. The retrieval mechanism includes a calibration pile, a limiting block, a retrieval lifting hole, a pile entry groove, a baffle, an electric push rod, a hydraulic telescopic rod, an adjusting placement plate, a slider, a fixed groove, and a pile. The calibration device for the post-insertion reinforced cage cast-in-place pile facilitates the smooth removal of concrete after the pile is used, effectively reducing the burden on subsequent users and greatly increasing the device's practicality. However, the existing device cannot be adapted to cast-in-place piles of different diameters. When the pile diameter changes, such as from 800mm to 1200mm, additional calibration components need to be replaced or modified, resulting in poor versatility and increased usage costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a calibrating device for cast-in-place piles, which aims to improve the problem that existing devices cannot be adapted to cast-in-place piles of different diameters, have poor versatility, and thus increase the cost of use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a grouting pile calibration device, comprising a ground base plate, an irrigation cylinder fixedly connected to the bottom of the ground base plate, and multiple clamping mechanisms equidistantly installed on the top of the ground base plate, the clamping mechanisms being used to clamp grouting piles of different sizes for calibration; a protective mechanism is installed on the top right side of the ground base plate, the protective mechanism being used to cover and protect the grouting piles after grouting; the clamping mechanism includes a movable plate, the movable plate being equidistantly installed on the top of the ground base plate, a semi-circular plate being fixedly connected to each adjacent side of the outer wall of the movable plate, a semi-circular spring plate being fixedly connected to each adjacent side of the outer wall of the semi-circular plate, and a driving assembly being installed on the front and rear sides of the top of the outer wall of the irrigation cylinder.

[0006] The above technical solution achieves adaptive clamping by having semi-circular spring plates on adjacent sides of the outer walls of the two semi-circular plates move closer together and contract.

[0007] As a further description of the above technical solution: The drive assembly includes an elongated hollow plate, which is installed on the front and rear sides of the outer wall of the irrigation cylinder. Threaded rods are rotatably connected to the inner wall of the elongated hollow plate, and worm gears are fixedly connected to the left end of the outer wall of each threaded rod. A worm is rotatably connected to the middle of the inner wall of the elongated hollow plate, and an electric drill is installed at the front end of the outer wall of the worm. Elongated grooves are formed on adjacent sides of the outer wall of the elongated hollow plate.

[0008] The above technical solution works as follows: when the electric drill is started, it drives the worm to start rotating. When the worm rotates, the worm wheel that meshes with it will be driven. Since the worm wheel is fixed to the left end of the threaded rod, the threaded rod will rotate synchronously with the worm wheel.

[0009] As a further description of the above technical solution: The protective mechanism includes an elastic protective reel, which is installed on the top right side of the base plate. A long plate is fixedly connected to the left end of the outer wall of the elastic protective reel, and a power assembly is installed on the front side of the outer wall of the long plate.

[0010] The above technical solution involves using a power component to pull the elongated plate, which in turn moves the elastic protective belt connected to it, causing it to unfold synchronously for protection.

[0011] As a further description of the above technical solution: The power assembly includes a motor, which is installed on the front side of the outer wall of the elongated plate. A fixed rod is fixedly connected to the output end of the motor. An inner sliding groove support frame is fixedly connected to the top right side of the base plate. Multiple square support plates are fixedly connected at equal intervals to the left side of the outer wall of the inner sliding groove support frame. A drum is rotatably connected to the adjacent side of the outer wall of the square support plates. A winding rope is installed on the outer wall of the drum.

[0012] The above technical solution involves starting a motor, which drives the fixed rod at the output end to rotate synchronously with the drum. The drum rewinds, and the rope pulls the elongated plate to slide to the left along the inner sliding groove support frame, thereby pulling out and unfolding the elastic protective tape from the left side to cover the cast-in-place pile. The elastic protective tape is made of flexible material and can freely expand and contract with the movement of the elongated plate. The left side of the tape is fixed to the inner sliding groove support frame, while the right side is unfolded and rewound through the sliding of the elongated plate. The elastic protective tape can effectively block direct ultraviolet radiation, reduce concrete moisture evaporation, prevent surface cracking, and adapt to the needs of different curing stages, thus improving the durability of the pile and the construction quality.

[0013] As a further description of the above technical solution: The other end of the outer wall of the coiled rope is fixedly connected to the left side of the outer wall of the elongated plate, and the outer wall of the elongated plate is slidably connected to the inside of the inner groove support frame.

[0014] The above technical solution allows the retraction of the coiled rope to move the elongated plate, thereby causing the elastic protective roll to unfold and provide protection.

[0015] As a further description of the above technical solution: A protective shell is fixedly connected to the left side of the outer wall of the inner slide groove support frame, and the left side of the outer wall of the elastic protective roll is fixedly connected to the right side of the outer wall of the inner slide groove support frame.

[0016] Through the above technical solution: the protective shell can protect the motor, and the inner slide groove support frame can fix the elastic protective tape for installation and use.

[0017] As a further description of the above technical solution: The worm gear is meshed with the worm wheel, the interior of the moving plate is threadedly connected to the outer wall of the threaded rod, and the outer wall of the moving plate is slidably connected to the interior of the elongated groove.

[0018] The above technical solution involves a worm gear meshing with a worm wheel, which drives a threaded rod to rotate. When the threaded rod rotates, it drives the outer wall moving plate to move. The elongated groove then restricts the direction and trajectory of the moving plate.

[0019] As a further description of the above technical solution: The bottom of the inner slide support frame is fixedly connected with multiple fixing plates at equal intervals, and the top of the fixing plates is threaded with multiple bolts at equal intervals.

[0020] The above technical solution enables quick disassembly and installation by tightening the bolts on the top of the fixing plate.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the worm gear is driven to rotate by starting the electric drill, and the threaded rod is driven to rotate by the worm wheel, so that the moving plate moves in a straight line along the long sliding groove. The moving plate drives the semi-circular spring plate to move closer to the center of the cast-in-place pile. The elasticity of the spring plate automatically adapts to different pile diameters to form an embracing structure, ensuring the verticality and positional accuracy of the cast-in-place pile.

[0022] 2. In this utility model, the starting motor drives the fixed rod and the drum to rotate synchronously. The winding rope of the drum pulls the long plate to slide along the inner sliding groove support frame, so that the elastic protective belt unfolds to cover the grouting pile. The flexible belt can freely extend and retract. It can be unfolded and rolled up by sliding the long plate, effectively preventing sun exposure and keeping the soil moist. It can adapt to different maintenance stages and improve the durability of the pile and the construction quality. Attached Figure Description

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.

[0026] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a calibrated pile, comprising a ground base plate 1, an irrigation cylinder 4 fixedly connected to the bottom of the ground base plate 1, and multiple clamping mechanisms 2 equidistantly installed on the top of the ground base plate 1 for clamping and calibrating calibrated piles of different sizes. A protective mechanism 3 is installed on the top right side of the ground base plate 1 for covering and protecting the calibrated piles. The clamping mechanism 2 includes a movable plate 201 equidistantly installed on the top of the ground base plate 1. A semi-circular plate 203 is fixedly connected to each adjacent side of the outer wall of the movable plate 201, and a semi-circular spring plate 202 is fixedly connected to each adjacent side of the outer wall of the semi-circular plate 203. A driving assembly 204 is installed on the front and rear sides of the top of the outer wall of the irrigation cylinder 4. The driving assembly 204 includes an elongated hollow... The core plate 2041 and the long hollow plate 2041 are installed on the front and rear sides of the outer wall of the irrigation cylinder 4. The inner wall of the long hollow plate 2041 is rotatably connected with threaded rods 2045. The left end of the outer wall of the threaded rods 2045 is fixedly connected with worm gears 2043. The middle of the inner wall of the long hollow plate 2041 is rotatably connected with a worm 2042. The front end of the outer wall of the worm 2042 is equipped with an electric drill 2044.

The outer wall of the long plate 302 is slidably connected to the inner groove support frame 3037. The long plate 302 can be moved by retracting the rope 3035, thereby driving the elastic protective belt 301 to unfold for protection. Specifically, starting the electric drill 2044 drives the worm gear 2042 to rotate. The worm gear 2042 meshes with the worm wheel 2043, transmitting the rotational motion to the two threaded rods 2045. Since the two threaded rods 2045 rotate within the elongated hollow plate 2041 with opposite threads, and since the moving plate 201 is threadedly connected to the threaded rods 2045 and slides and is limited by the elongated groove 2046, the rotation of the threaded rods 2045 drives the moving plate 201 to move linearly along the elongated groove 2046. The moving plate 201 drives the semi-circular plate 203 and the semi-circular spring plate 202 to move synchronously, causing multiple... A semi-circular spring plate 202 moves towards the center of the cast-in-place pile. The semi-circular spring plate 202 is elastic and can automatically deform according to the pile diameter when it contacts the outer wall of the cast-in-place pile, forming a tightly fitting ring structure. This enables adaptive clamping of cast-in-place piles of different diameters, ensuring that the verticality and center position of the cast-in-place pile meet the design requirements during the calibration process.

The protective shell 3032 can protect the motor 3031. The inner slide support frame 3037 can fix the elastic protective belt 301 for installation and use. Specifically, by starting the motor 3031, the fixed rod 3033 at the output end and the drum 3034 rotate synchronously. The drum 3034 winds up the rope 3035, which pulls the elongated plate 302 to slide to the left along the inner sliding groove support frame 3037, thereby pulling out and unfolding the elastic protective tape 301 from the left side to cover the cast-in-place pile. The elastic protective tape 301 is made of flexible material and can freely expand and contract with the movement of the elongated plate 302. The left side of the tape is fixed to the inner sliding groove support frame 3037, and the right side is unfolded and wound up by sliding the elongated plate 302. The elastic protective tape 301 can effectively block direct ultraviolet rays, reduce concrete moisture evaporation, prevent surface cracking, and adapt to the needs of different curing stages, improving the durability of the pile and construction. The quality is achieved by starting the motor 3031, which drives the fixed rod 3033 at the output end to rotate synchronously with the drum 3034.

[0029] Working principle: Starting the electric drill 2044 drives the worm gear 2042 to rotate. The worm gear 2042 meshes with the worm wheel 2043, transmitting the rotational motion to the two threaded rods 2045. Since the two threaded rods 2045 rotate within the elongated hollow plate 2041 with opposite threads, and because the moving plate 201 is threadedly connected to the threaded rods 2045 and slides and is limited by the elongated groove 2046 against the elongated hollow plate 2041, the rotation of the threaded rods 2045 is driven... The movable plate 201 moves linearly along the elongated slide 2046. The movable plate 201 drives the semi-circular plate 203 and the semi-circular spring plate 202 to move synchronously, so that multiple semi-circular spring plates 202 move closer to the center of the cast-in-place pile. The semi-circular spring plates 202 are elastic and can automatically deform according to the pile diameter when they contact the outer wall of the cast-in-place pile, forming a tightly fitting ring structure, realizing adaptive clamping of cast-in-place piles of different diameters, and ensuring that the verticality and center position of the cast-in-place pile meet the design requirements during the calibration process. By starting the motor 3031, the fixed rod 3033 at the output end and the drum 3034 rotate synchronously. The drum 3034 winds up the rope 3035, and the rope 3035 pulls the elongated plate 302 to slide to the left along the inner sliding groove support frame 3037, thereby pulling out and unfolding the elastic protective tape 301 from the left side to cover the top of the cast-in-place pile.
