A device for correcting deviation during caisson construction

Abstract

This utility model provides a caisson construction correction device, including a central support frame and a top frame. A bidirectional screw is rotatably connected to the middle position inside the central support frame. Transmission groove plates are spirally connected to the upper and lower sides of the bidirectional screw. A transmission rod is rotatably connected to the side of the transmission groove plate. A correction top pressure plate is rotatably connected to the outer end of the transmission rod. This utility model can be installed on a crane via a hook and placed inside the caisson by the crane. Rotation of a stepper motor drives the bidirectional screw to move the upper and lower transmission groove plates in opposite directions, thereby enabling the transmission rod to drive four correction top pressure plates to move simultaneously outward or inward. This allows the four correction top pressure plates to perform concentric point correction on two connected circular templates and to correct the alignment of square templates. After correction, the templates can be removed, making it more convenient and faster to use, while also improving the correction effect.

Description

Technical Field

[0001] This utility model relates to the field of caisson construction technology, and in particular to a caisson construction correction device. Background Technology

[0002] During the construction of caissons, due to various factors such as uneven soil quality, asymmetrical excavation, uneven stress at the cutting edge, and unfavorable geological conditions, the caisson sinks at an uneven rate, making it easy for the caisson to tilt or deviate. If this deviation is not corrected in time, it will lead to difficulties in the subsequent sinking of the caisson, affect the accuracy of the final position of the structure, and may also cause quality problems such as uneven stress on the caisson wall and cracks.

[0003] A caisson construction correction device with existing patent number CN119686362A has a lifting module that applies downward pressure to the highest point, and a rope pulling module that pulls the gripper to apply downward pull to both ends of the highest point to prevent stress concentration during correction and deformation of the caisson wall. The ground anchor can change the direction of the force to adjust the position of the cable. This invention can apply pressure precisely to prevent excessive pressure from causing secondary displacement of the caisson. It can also apply force from multiple directions to ensure uniform force distribution during caisson correction and improve the stability of correction.

[0004] 1. This device requires the construction of a support frame during use, and can only perform one-sided correction during the correction process. This can easily cause the connected templates to deviate from front to back, and it is difficult to correct the deviation of caisson construction templates of different shapes.

[0005] Second, although this device is equipped with a pressing mechanism on one side, this pressing mechanism cannot press down in different directions at the same time. The correction and pulling ropes also pull to one side, which will also cause the template to tilt. It is impossible to correct the installation at the same time as the template can be installed smoothly.

[0006] To address this, a caisson construction correction device is proposed. Utility Model Content

[0007] In view of this, the present invention provides a caisson construction correction device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0008] The technical solution of this utility model is achieved as follows: a caisson construction correction device, comprising a central support frame and a top frame:

[0009] A bidirectional screw is rotatably connected to the inner middle position of the central support frame. Both the upper and lower sides of the bidirectional screw are helically connected to transmission groove plates, which are slidably connected to the central support frame. A transmission rod is rotatably connected to the side of the transmission groove plate, and a correction pressure plate is rotatably connected to the outer end of the transmission rod. A top frame is fixedly connected to the upper end of the central support frame. A threaded shaft is provided on the inner side of the top frame, and the threaded shaft is rotatably connected to the upper wall of the central support frame. A cross plate is helically connected to the outer side of the threaded shaft, and the cross plate is slidably connected to the top frame. An electric telescopic rod is fixedly connected to the middle position of the outer end of the cross plate, and a mounting pressure frame is fixedly connected to the outer end of the inner movable rod of the electric telescopic rod.

[0010] More preferably, a stepper motor is fixedly connected at the lower middle position of the central support frame, and the output shaft of the stepper motor is fixedly connected to the bidirectional screw.

[0011] More preferably, there are four correction top pressure plates, which are arranged symmetrically about the central axis of the central support frame.

[0012] More preferably, a limiting telescopic rod is fixedly connected at the middle position of the outer side of the central support frame, and the inner movable rod of the limiting telescopic rod is fixedly connected to the correction top pressure plate.

[0013] More preferably, a top plate is fixedly connected to the upper end of the top frame, a motor box is fixedly connected to the middle position of the upper end of the top plate, and a hook is fixedly connected to the upper end of the motor box.

[0014] More preferably, a drive motor is fixedly connected inside the motor housing, the output shaft of the drive motor is fixedly connected to a threaded shaft, and the threaded shaft is rotatably connected to the motor housing and the top plate respectively.

[0015] More preferably, a limiting rod is fixedly connected to the outer side of the inner end face of the mounting frame, the limiting rod is slidably connected to the cross plate, and an insertion hole is opened inside the outer plate of the cross plate. The position and size of the insertion hole correspond to the position and size of the limiting rod. There are four mounting frames, and the mounting frames are symmetrically arranged about the central axis of the cross plate.

[0016] More preferably, an anti-slip plate is fixedly connected to the lower side of the outer end face of the correction top pressure plate, and a top pressure roller is rotatably connected to the upper side of the outer end face of the correction top pressure plate.

[0017] The present invention has the following advantages due to the adoption of the above technical solution:

[0018] I. This utility model can be installed on a crane using a hook, and placed inside the caisson by the crane. The rotation of the stepper motor causes the bidirectional screw to drive the upper and lower transmission slot plates to move in opposite directions, thereby enabling the transmission rod to drive the four correction top pressure plates to move outward or inward simultaneously. This allows the four correction top pressure plates to perform concentric point correction on the two connected circular templates and to correct the position of the square template. After correction, the template can be removed, making it more convenient and faster to use, while also improving the correction effect.

[0019] II. This utility model uses the rotation of a drive motor to enable the threaded shaft to rotate, thereby allowing the cross plate to move up and down. The electric telescopic rod drives the installation pressure frame to move outward to adjust its position, so as to adjust it according to the position of the upper wall of the template. It can also achieve simultaneous pressing and installation docking in four directions. During correction, the top pressure roller can provide rolling support for the template to be installed on the upper side, so that the correction mechanism and the installation pressing mechanism can operate simultaneously without affecting each other.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, this embodiment of the utility model provides a caisson construction correction device, including a central support frame 1 and a top frame 6:

[0030] A bidirectional screw 2 is rotatably connected to the center of the central support frame 1. Both the upper and lower sides of the bidirectional screw 2 are helically connected to transmission groove plates 3, which are slidably connected to the central support frame 1. A transmission rod 4 is rotatably connected to the side of the transmission groove plate 3, and a correction pressure plate 5 is rotatably connected to the outer end of the transmission rod 4. The rotation of the bidirectional screw 2 drives the upper and lower transmission groove plates 3 to move in opposite directions, thereby enabling the transmission rod 4 to drive the correction pressure plate 5 to move outward or inward. A top frame 6 is fixedly connected to the upper end of the central support frame 1, and a threaded shaft 7 is provided on the inner side of the top frame 6. The threaded shaft 7 is connected to the central support frame 1... The upper walls are rotatably connected, and a cross plate 8 is spirally connected to the outer side of the threaded shaft 7. The cross plate 8 is slidably connected to the top frame 6. An electric telescopic rod 9 is fixedly connected to the middle position of the outer end of the cross plate 8. An installation pressure frame 10 is fixedly connected to the outer end of the inner movable rod of the electric telescopic rod 9. The cross plate 8 can be moved and guided by the action of the top frame 6, and the cross plate 8 can be moved up and down by the rotation of the threaded shaft 7, so as to press the template down for installation. The electric telescopic rod 9 can drive the installation pressure frame 10 to adjust its position, so as to adjust it according to the size of the template and improve the applicability of the device.

[0031] In one embodiment, a stepper motor 11 is fixedly connected at the lower middle position of the central support frame 1. The output shaft of the stepper motor 11 is fixedly connected to the bidirectional screw 2. The stepper motor 11 can be automatically controlled by the control terminal to achieve automatic correction of the template installation.

[0032] In one embodiment, there are four correction top pressure plates 5, which are symmetrically arranged about the central axis of the central support frame 1, so that the four correction top pressure plates 5 can perform concentric correction and alignment processing on the two mating templates, ensuring the correction effect.

[0033] In one embodiment, a limiting telescopic rod 12 is fixedly connected at the middle position of the outer side of the central support frame 1. The inner movable rod of the limiting telescopic rod 12 is fixedly connected to the correction top pressure plate 5. The limiting telescopic rod 12 can prevent the correction top pressure plate 5 from tilting due to its supporting and limiting effect.

[0034] In one embodiment, a top plate 13 is fixedly connected to the upper end of the top frame 6, a motor box 14 is fixedly connected to the middle position of the upper end of the top plate 13, and a hook 15 is fixedly connected to the upper end of the motor box 14. The device can be quickly installed by hanging it on a crane through the action of the hook.

[0035] In one embodiment, a drive motor 16 is fixedly connected inside the motor housing 14. The output shaft of the drive motor 16 is fixedly connected to a threaded shaft 7. The threaded shaft 7 is rotatably connected to the motor housing 14 and the top plate 13 respectively. The rotation of the drive motor 16 enables the threaded shaft 7 to rotate quickly, so as to facilitate the rapid installation of the docking template.

[0036] In one embodiment, a limiting rod 17 is fixedly connected to the outer side of the inner end face of the mounting frame 10. The limiting rod 17 is slidably connected to the cross plate 8. An insertion hole 18 is provided inside the outer plate of the cross plate 8. The position and size of the insertion hole 18 correspond to the position and size of the limiting rod 17. The limiting rod 17 can provide stable support and limit the mounting frame 10. There are four mounting frames 10. The mounting frames 10 are symmetrically arranged about the central axis of the cross plate 8, which can simultaneously press down on the four points of the mating template to avoid uneven pressure and tilting of the mating template.

[0037] In one embodiment, an anti-slip plate 19 is fixedly connected to the lower side of the outer end face of the correction top pressure plate 5. The anti-slip plate can fit tightly against the inner wall of the lower template. A top pressure roller 20 is rotatably connected to the upper side of the outer end face of the correction top pressure plate 5, so that the upper installation template can move downward smoothly, ensuring that correction and downward pressure installation can be carried out simultaneously, thereby improving the construction quality of the caisson.

[0038] In operation, this invention works as follows: First, the device is suspended on a crane using hook 15. The crane then moves the device to the inside of the caisson. The required mating template is installed on the upper end of the lower template. The stepper motor 11 is controlled to rotate via a remote control terminal, causing the bidirectional screw 2 to rotate. This drives the upper and lower transmission slot plates 3 to move towards each other, and the transmission rod 4 drives the four correction top pressure plates 5 to move outward simultaneously. At this time, the limiting telescopic rod 12 provides stable limiting support for the correction top pressure plates 5, allowing the outer end of the correction top pressure plates 5 to perform concentric correction and alignment of the two circular or square mating templates. After the upper template is aligned, the electric telescopic rod 9 and the limiting rod 17 are used to extend and retract the four mounting pressure frames 1. The 0 can move outwards simultaneously, and the rotation of the drive motor 16 causes the threaded shaft 7 to rotate, thereby allowing the cross plate 8 to move downwards along the direction of the top frame 6. At the same time, it drives the electric telescopic rod 9, the limit rod 17, and the installation pressure frame 10 to move downwards, so that the installation pressure frame 10 can simultaneously press and install the upper end of the required docking template in four directions, ensuring that the docking template can be installed stably and avoiding the deviation of the docking template caused by pressing down at a single point. During the pressing and installation process, the anti-slip plate 19 can stably fit against the inner side of the lower template, while the set top pressure roller 20 can ensure that the upper template can be pressed and installed quickly and correctly, so that the correction and pressing installation can be carried out simultaneously without affecting each other, ensuring the construction quality.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
