Description

Technical Field

[0001] This application relates to the field of pile foundation construction technology, and for example to a pile foundation positioning and anti-deviation device. Background Technology

[0002] A related technology (publication number: CN219653712U) discloses a pile foundation positioning and anti-deviation device for pile foundation engineering, including an annular base, several clamping plates, and a tightening structure. The annular base is assembled from a pair of semi-annular base plates, through which the pile foundation passes. Several clamping plates are evenly distributed along the circumference of the pile foundation, and the pile foundation is clamped between each clamping plate. The clamping plates are connected to the annular base by support rods, and the two ends of the support rods are respectively hinged to the back of the clamping plates and the upper side of the base plates. The tightening structure is used to fix the clamping plates to the pile foundation. The tightening structure includes an internally threaded bidirectional threaded cylinder and a pair of threaded rods. The two threaded rods are respectively threaded onto the upper and lower parts of the internally threaded bidirectional threaded cylinder, and the ends of the two threaded rods away from the internally threaded bidirectional threaded cylinder are respectively hinged to the middle of the support rod and the upper side of the base plate. An adjusting handwheel is fixedly fitted into the middle of the internally threaded bidirectional threaded cylinder.

[0003] In implementing the above embodiments, at least the following problems were found in the related technology:

[0004] During use, the device drives the two internal threaded cylinders on both sides to rotate. Through the interaction between the threads, the extension length of the threaded rods on both sides can be changed, thereby causing the support rods on both sides to rotate. Ultimately, the clamping plates on both sides abut against the pile foundation, positioning the pile foundation and preventing it from deviating. However, manually driving the two internal threaded cylinders on both sides to rotate has a large error and can easily cause the extension length of the threaded rods on both sides to be different, resulting in uneven stress on the pile foundation and tilting, thus resulting in poor positioning and deviating prevention effect.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0009] Optionally, it further includes: cam bearings, respectively installed between the first bracket and the support arm on the same side; wherein the bolts of the cam bearings on both sides are respectively connected to the first brackets on both sides, and the thick outer ring needle roller bearings of the cam bearings on both sides are respectively connected to the support arms on both sides.

[0010] Optionally, it further includes: a first linear bearing, which is respectively mounted on the second bracket on both sides; wherein the first optical axis on both sides is respectively mounted inside the first linear bearing on both sides.

[0015] Optionally, it also includes: a first reinforcing plate, fixed to the bend of the first bracket.

[0016] Optionally, it also includes a second reinforcing plate, fixed to the bend of the second bracket.

[0017] The pile foundation positioning and anti-deviation device provided in this embodiment can achieve the following technical effects:

[0018] This disclosure provides a pile foundation positioning and anti-deviation device, comprising a support plate, a first bracket, a support arm, a second bracket, a first optical axis, a support block, a second optical axis, a clamping block, a movable plate, and a hydraulic cylinder. The support plate includes a first notch for accommodating the pile foundation. The first bracket is connected to the support plate and located on both sides of the support plate along its length, with each first bracket supporting a rotatable support plate. The support arm is rotatably mounted on both first brackets and can rotate relative to each first bracket. The second bracket is connected to the support plate and adjacent to both first brackets, supporting a slidable first optical axis. The first optical axis slidably passes through both second brackets along the thickness of the support plate and can move linearly relative to each second bracket. The support block is connected to one end of each first optical axis and supports a slidable second optical axis. The second optical axis is slidably mounted on both support blocks along the length of the support plate and can move linearly relative to each support block. The clamping blocks are respectively connected to one end of the two second optical axes on both sides, and are used to abut against the pile foundation. The other ends of the two second optical axes are rotatably connected to the two support arms on both sides, and move under the drive of the two support arms. The movable plate is connected to the other end of the two first optical axes on both sides, and is used to make the two second optical axes move synchronously. The movable plate includes a second notch, which is also used to accommodate the pile foundation. After the pile foundation is accommodated inside the first notch and the second notch, it is located between the two clamping blocks. The hydraulic cylinder is rotatably mounted between the two support arms on both sides, and can rotate relative to the two support arms on both sides, and is used to provide driving force.

[0019] During operation, the hydraulic cylinders are controlled to rotate the support arms on both sides relative to the first supports on both sides. Then, guided and supported by the first optical axes on both sides, the second optical axes on both sides drive the support blocks on both sides to move longitudinally. Simultaneously, this causes the clamping blocks on both sides to move closer or further apart, thereby clamping or releasing the pile foundation located within the first and second notches, thus achieving a positioning and anti-deviation function. Furthermore, the design of the movable plate allows the first optical axes on both sides to move synchronously. This, in turn, causes the support blocks on both sides to rise or fall synchronously, ultimately enabling the second optical axes on both sides to drive the clamping blocks on both sides to simultaneously clamp or release the pile foundation. This prevents the pile foundation from tilting due to uneven force distribution, improving the positioning and anti-deviation effect of the pile foundation.

The hydraulic cylinder 10 is rotatably mounted between the two support arms 3. Both the first and second notches are used to accommodate the pile foundation.

[0037] This disclosure provides a pile foundation positioning and anti-deviation device, comprising a support plate 1, a first bracket 2, a support arm 3, a second bracket 4, a first optical axis 5, a support block 6, a second optical axis 7, a clamping block 8, a movable plate 9, and a hydraulic cylinder 10. The support plate 1 includes a first notch for accommodating the pile foundation. The first bracket 2 is connected to the support plate 1 and located on both sides of the support plate 1 along its length, with each side supporting a rotatable support plate 1. The support arm 3 is rotatably mounted on both sides of the first bracket 2 and can rotate relative to each side of the first bracket 2. The second bracket 4 is connected to the support plate 1 and is adjacent to both sides of the first bracket 2, supporting a slidable first optical axis 5. The first optical axis 5 slidably passes through both sides of the second bracket 4 along the thickness direction of the support plate 1 and can move linearly relative to each side of the second bracket 4. The support block 6 is connected to one end of each side of the first optical axis 5 and supports a slidable second optical axis 7. The second optical axis 7 is slidably mounted on the two side support blocks 6 along the length of the support plate 1, and can move linearly relative to the two side support blocks 6. Clamping blocks 8 are connected to opposite ends of the two side second optical axes 7, and are used to abut against the pile foundation. The other ends of the two side second optical axes 7 are rotatably connected to the two side support arms 3, and move under the drive of the two side support arms 3.

[0038] During operation, the hydraulic cylinder 10 is activated, allowing the support arms 3 on both sides to rotate relative to the first supports 2 on both sides. Then, guided by the first optical axes 5 on both sides, the second optical axes 7 on both sides drive the support blocks 6 on both sides to move longitudinally. Simultaneously, this causes the clamping blocks 8 on both sides to move closer or further apart, thus clamping or releasing the pile foundation located within the first and second notches, achieving a positioning and anti-deviation effect.

This prevents the pile foundation from tilting due to uneven force distribution, improving the positioning and anti-deviation effect of the pile foundation.
