Abstract
Description
Technical Field
[0001] This application belongs to the field of building construction, specifically to a soft soil foundation deflection correction device with sensors. Background Technology
[0002] There are many reasons for pile deviation, such as the lack of protective measures for the layout points, human movement, or measurement and positioning errors; encountering isolated boulders or sloping hard rock layers, which may cause the drill bit to deflect or be subjected to uneven force; during concrete pouring, if the speed is too fast or the guide pipe is not operated properly, the reinforcing cage may float and shift. Pile deviation correction is an important task in pile foundation construction, mainly dealing with situations where the pile body position deviation exceeds the allowable range.
[0003] Correcting pile misalignment includes correcting the reinforcement cage. If the reinforcement cage also shifts during the pile correction process, it needs to be corrected simultaneously. This may require adjusting the position of the reinforcement cage or taking reinforcement measures to enhance its stability.
[0004] In the current pile foundation construction process, if the position of the pile foundation reinforcement cage is offset, when correcting the position of the pile foundation reinforcement cage, whether the position is back to the correct position after correction basically depends entirely on the visual observation and experience of the construction personnel. Under this judgment, the probability of error is relatively large, so the pile foundation reinforcement cage that needs to be corrected is not adjusted to the correct position during the correction. Utility Model Content
[0005] The purpose of this invention is to provide a soft soil foundation pile deviation correction device with a sensor. It aims to solve the problem that when correcting the pile position of the pile foundation reinforcement cage, relying solely on the naked eye of the workers for observation and judgment results in a relatively large positional error after correction. This application combines mechanical and manual observation and judgment, and the mechanical correction can improve construction efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A soft soil foundation pile deviation correction device with sensors is characterized in that it includes a carrier and a correction device body. The carrier includes a shell and a drive assembly. The shell includes a lower shell for supporting the drive assembly and a lifting shell. The drive assembly drives the lifting shell to move up and down. The correction device body is fixed on the lifting shell. The correction device body includes an electric telescopic rod, a damping shaft, a device bearing shell, a verticality sensor, and a pile foundation reinforcement cage adjustment assembly disposed on the device bearing shell. The pile foundation reinforcement cage adjustment assembly includes a transverse threaded rod, a motor for driving the transverse threaded rod, a sliding plate, and an arc-shaped push plate disposed at the lower part of the sliding plate. The sliding plate is threadedly connected to the transverse threaded rod. The transverse threaded rod rotates forward or backward, driving the sliding plate to move left and right.
[0008] More preferably, the arc-shaped push plate is positioned with its arc opening facing the pile foundation reinforcement cage, and a number of rubber blocks are evenly spaced on the inner wall of the arc opening.
[0009] Furthermore, the drive assembly includes a dual-axis motor, a first rotating rod and a second rotating rod symmetrically connected to both sides of the output end of the dual-axis motor. The ends of the first rotating rod and the second rotating rod are each provided with a driven assembly. The driven assembly includes a driving pulley, a belt, and a driven pulley. The driven pulley is connected to a bevel gear one via a connecting round steel rod. The first bevel gear one meshes with a second bevel gear two located on a vertical threaded rod. The lifting housing includes an inner shell and an outer shell. The top surface of the outer shell is provided with an opening, and the inner cavity forms a vertical displacement limiting channel for the inner shell. The vertical threaded rod is threadedly connected to the bottom wall of the inner shell.
[0010] Furthermore, the inner shells on both sides are connected by a top plate, the electric telescopic rod is fixed to the bottom surface of the top plate, the electric telescopic rod is connected to the device bearing shell through a damping shaft, and the verticality sensor is attached to the outer wall of the device bearing shell.
[0011] Furthermore, the first rotating rod and the second rotating rod are connected to the dual-axis motor via a coupling.
[0012] In addition, the top plate and the inner shells on both sides form a portal structure, and the body of the correction device is located on the bottom surface of the top plate between the inner shells on both sides.
[0013] More preferably, the drive assembly, lifting assembly, and correction device body are all in communication with the CNC device.
[0014] Compared with the prior art, this utility model has the following features and beneficial effects:
[0015] This invention, by setting up two symmetrical lifting components, allows the correction component to be adjusted to a state that facilitates correction of the pile foundation reinforcement cage in outdoor environments with uneven terrain. This enables the correction component to better complete the correction work of the pile foundation reinforcement cage. The correction component can complete the correction work of the pile foundation reinforcement cage. At the same time, during the correction process, manual judgment combined with equipment is used to determine whether the pile foundation reinforcement cage has been adjusted to the required position after correction. This avoids the situation where construction workers rely solely on visual observation and experience to determine whether the position of the pile foundation reinforcement cage has been corrected, resulting in a large positional error of the pile foundation reinforcement cage after correction.
[0016] This invention utilizes a dual-axis motor, allowing the two lifting components to operate independently. This enables the two lifting components to better adjust the position of the correction device according to uneven outdoor terrain. The damping shaft allows the moving component to be rotated during the correction process, changing its state and enabling it to perform correction work on the pile foundation reinforcement cage from different directions and angles.

[0024] A device for correcting pile deviation in soft soil foundations with sensors, such as Figures 1-5As shown, the device includes a carrier and a correction device body. The carrier includes a housing 1 and a drive assembly 2. The housing 1 includes a lower housing for supporting the drive assembly 2 and a lifting housing. The drive assembly 2 drives the lifting housing to move up and down. The correction device body 5 is fixed on the lifting housing. The correction device body 5 includes an electric telescopic rod 51, a damping shaft 52, a device bearing housing 53, a verticality sensor 56, and a pile foundation reinforcement cage adjustment assembly 55 disposed on the device bearing housing 53. The pile foundation reinforcement cage adjustment assembly 55 includes a transverse threaded rod 552, a motor 551 for driving the transverse threaded rod 552, a sliding plate 553, and an arc-shaped push plate 554 disposed at the lower part of the sliding plate 553. The sliding plate 553 is threadedly connected to the transverse threaded rod 552. The transverse threaded rod 552 rotates forward or backward, driving the sliding plate 553 to move left and right.
[0025] The arc-shaped push plate 554 is set with its arc opening facing the pile foundation reinforcement cage, and a number of rubber blocks 555 are evenly spaced on the inner wall of the arc opening. The rubber blocks 555 are fixed by adhesive.
[0026] The drive assembly 2 includes a dual-axis motor 22, a first rotating rod 21 and a second rotating rod 23 symmetrically connected to both sides of the output end of the dual-axis motor 22. The ends of the first rotating rod 21 and the second rotating rod 23 are provided with driven components. The driven components include a driving pulley 24, a belt 25 and a driven pulley 26. The driven pulley 26 is connected to a first bevel gear 28 through a connecting round steel rod 27. The first bevel gear 28 meshes with a second bevel gear 30 provided on the vertical threaded rod 29. The lifting housing includes an inner shell and an outer shell. The top surface of the outer shell is provided with an opening, and the inner cavity forms a vertical displacement limiting channel for the inner shell. The vertical threaded rod 29 is threadedly connected to the bottom wall of the inner shell.
[0027] The two inner shells are connected by the top plate 4. The electric telescopic rod 51 is fixed to the bottom surface of the top plate 4 (which is equivalent to the fixed plate of the entire correction device). The electric telescopic rod 51 is connected to the device bearing shell 53 through the damping shaft 52. The verticality sensor 56 is attached to the outer wall of the device bearing shell 53. Rotating rod 1 21 and rotating rod 23 are connected to the dual-axis motor 22 through the coupling. The top plate 4 and the two inner shells form a portal structure. The correction device body 5 is located on the bottom surface of the top plate 4 between the two inner shells. The drive assembly 2, the lifting assembly 3 and the correction device body 5 all communicate with the CNC device and can control the operation of the entire equipment through the controller and remote control.
[0028] Specifically, two embodiments of this application are as follows:
[0029] A soft soil foundation deflection correction device with sensors includes a main shell, a drive assembly is provided on the lower front of the inner surface of the main shell, lifting assemblies are symmetrically arranged on the left and right sides of the rear side of the drive assembly, a fixing plate is fixedly connected to the upper side of the two lifting assemblies, and a correction assembly is provided in the middle of the lower end of the fixing plate.
[0030] In practice, with the help of construction machinery, the device is moved to a position where the correction component is above the steel cage that needs to be corrected. Depending on the terrain and the offset of the pile foundation steel cage, the drive component is activated to drive the two lifting components to operate independently. The position of the correction component is adjusted to a state that facilitates the correction of the pile foundation steel cage. Then, the correction component is activated to begin the correction work on the pile foundation steel cage.
[0031] Specifically, in order to adjust the position of the correction component according to the uneven outdoor terrain and the degree of deviation of the pile foundation reinforcement cage, so that the correction component can better complete the correction work of the pile foundation reinforcement cage, the drive component includes a dual-axis motor, which is fixedly connected to the lower front part of the inner surface of the main body shell. The right output end of the dual-axis motor is fixedly connected to a rotating rod one through a coupling, and the left output end of the dual-axis motor is fixedly connected to a rotating rod two through a coupling; the lifting component includes a driven component, and a threaded rod component is provided on the left side of the driven component;
[0032] The driven component includes a round rod, which is rotatably connected to the rear right side of the inner surface of the main body shell. A pulley is fixedly connected to the right side of the outer surface of the round rod. The front pulley is fixedly connected to the outer surface of the rotating rod. A bevel gear is fixedly connected to the left side of the outer surface of the round rod. The threaded rod assembly includes a threaded rod, which is rotatably connected to the lower right side of the inner surface of the main body shell. A bevel gear is fixedly connected to the lower side of the outer surface of the threaded rod. The bevel gear meshes with the bevel gear. A rectangular box is threadedly connected to the outer surface of the threaded rod. The rectangular box is slidably connected to the rear right side of the inner surface of the main body shell.
[0033] The aforementioned dual-axis motor comprises two independent rotating shafts with perpendicular rotation axes. The two shafts can receive different current signals, thereby independently controlling their respective speeds and directions. This is a mature technology in the existing field. This solution only borrows its function of controlling two objects to run simultaneously and independently, and its structure and working principle will not be elaborated further here.
[0034] In practical implementation, after moving the device to a position above the pile foundation reinforcement cage that needs to be corrected, the dual-axis motor is turned on to drive rotating rod one and rotating rod two to rotate, depending on the different terrain elevations and the offset state of the pile foundation reinforcement cage. Under the action of the two pulleys, the two round rods rotate, thereby driving the two bevel gears to rotate. Since the bevel gears one and two on the same side are meshed, the two bevel gears one rotate, thereby driving the two bevel gears two to rotate, thereby driving the two threaded rods one to rotate, thereby driving the two rectangular boxes to move up and down. The two rectangular boxes are slidably connected to the left and right sides of the inner surface of the main body shell, which can limit the up and down movement of the two rectangular boxes.
[0035] The two rectangular boxes move up and down to adjust the correction component to the required position. Due to the presence of the dual-axis motor, the up and down movement of the two rectangular boxes can be controlled independently. Thus, the height of the two rectangular boxes can be adjusted to the same height or different heights as needed. Therefore, during the correction process, the position of the correction component can be adjusted to a state that can better complete the correction work according to the correction situation.
[0036] Specifically, in order to better complete the correction operation of the pile foundation steel cage, the correction component includes an electric telescopic rod, which is fixedly connected to the middle of the lower end of the fixed plate. The lower end of the piston rod at the output end of the electric telescopic rod is fixedly connected to a damping shaft, and the lower end of the damping shaft is fixedly connected to a fixed housing. A verticality sensor is fixedly connected to the upper right part of the fixed housing, and a moving component is provided on the inner surface of the fixed housing.
[0037] The moving component includes a motor, which is fixedly connected to the right end of the fixed housing. The output end of the motor is fixedly connected to a threaded rod II via a coupling. The left end of the threaded rod II passes through the right end of the fixed housing and extends into the fixed housing. A sliding plate is threadedly connected to the outer surface of the threaded rod II. The sliding plate is slidably connected to the front and rear sides of the inner surface of the fixed housing. An arc-shaped push plate is fixedly connected to the lower left end of the sliding plate. Several rubber blocks are fixedly connected to the inner left side of the arc-shaped push plate.
[0038] The damping shaft mentioned above is a mature technology in the existing technology. It consists of two parts that can rotate relative to each other. This solution only uses the function of the object that is fixedly connected to it to generate a certain resistance after rotation, so that it will not rotate randomly and return to its original position. Its structure and working principle will not be elaborated further here.
[0039] The aforementioned perpendicularity sensor can accurately measure the tilt angle of an object's surface or structure relative to a horizontal or vertical plane, ensuring that the perpendicularity of the object or structure meets design requirements or standard specifications. It is a mature technology in the existing technology. This solution only borrows its function of accurately measuring perpendicularity, and its structure and working principle will not be elaborated further here.
[0040] In practice, by raising and lowering two rectangular boxes, the position of the moving component is adjusted to a state that can better complete the correction work of the pile foundation steel cage. The electric telescopic rod is activated, so that the position of the moving component is lowered and the arc-shaped push plate is adjusted to a position that can push the pile foundation steel cage, thereby starting the correction work.
[0041] The verticality sensor and motor are activated, which drives the threaded rod to rotate, thereby moving the slide away from the verticality sensor. The slide slide is slidably connected to the inner surface of the fixed shell, which can limit the movement of the slide slide. The movement of the slide slide drives the arc-shaped push plate to move, thereby pushing the pile foundation steel cage and starting the correction work of the pile foundation steel cage. Several rubber blocks can increase the friction, making the process of the arc-shaped push plate pushing the pile foundation steel cage more stable.
[0042] During the correction process, a verticality sensor is used to measure whether the steel cage is vertical after correction, thereby reducing the error in the position of the steel cage after correction.
[0043] During the correction process, by rotating the fixed outer shell, the position of the arc-shaped push plate is changed, allowing the arc-shaped push plate to push the pile foundation steel cage at different positions and angles, thereby better completing the correction work of the pile foundation steel cage.
[0044] It should be noted that the dual-axis motor, electric telescopic rod, motor installation method, circuit connection method, and control method used in this utility model are all conventional designs, and will not be described in detail here.
[0045] The working principle of this utility model is as follows:
[0046] With the help of construction machinery, the device is moved to a position where the moving component is above the pile foundation reinforcement cage that needs to be corrected. Depending on the different outdoor terrain elevations and the degree of offset of the pile foundation reinforcement cage, the dual-axis motor is turned on, so that the two rectangular boxes move up and down at the same time. The moving component is adjusted so that the arc-shaped push plate can better push the position of the pile foundation reinforcement cage.
[0047] Then, activate the electric telescopic rod to extend the piston rod, adjust the arc-shaped push plate to face the pile foundation reinforcement cage, and then activate the verticality sensor and electricity to move the arc-shaped push plate and push the pile foundation reinforcement cage to start the pile foundation reinforcement cage correction work. The verticality sensor can measure the verticality of the pile foundation reinforcement cage after correction.
[0048] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
