Description

Technical Field

[0001] The invention belongs to the technical field of occlusal pile construction, and particularly relates to an occlusal pile verticality adjustment device and a method thereof. Background Art

[0002] Interlocking piles are a type of foundation pit retaining structure with interlocking piles. The construction steps include: first constructing two side-by-side A piles: A1 and A2, then constructing B piles: B1, and then constructing B2, A3, B3, A4, and so on, in the order of arrangement. Interlocking piles are constructed using casing. This involves clamping the casing with casing construction equipment, then using a tester to verify that the casing meets the standard verticality. Excavation and soil removal are then carried out, and concrete is poured while the casing is slowly removed.

[0003] However, simply using a detector to check the verticality of the casing before drilling can affect the verticality of the pile if the casing deviates during construction. Therefore, the verticality of the interlocking pile needs to be adjusted during the construction process. Prior art, such as Chinese Patent Publication No. CN 212052762 U, discloses a vertical positioning device for bored interlocking pile installation. This device rotates a rotating plate to align with the casing to ensure the verticality of the interlocking pile. However, due to the uneven flatness of the ground, if the T-shaped slide rail that prevents the plate from rotating is installed on uneven ground, the plate will tilt from the source, affecting the accuracy of verticality adjustment. Another example is a bored interlocking pile casing for deep foundation pit construction disclosed in a Chinese patent with announcement number CN111980018 A. A receiving ring is sleeved on the outside of the casing, and four horizontal channel steels are evenly arranged on the outside of the receiving ring. A load block is slidably connected to each horizontal channel steel. Therefore, when the casing tilts to one side, the user can quickly find that the load block will slide along the light rod, and the top pin at its bottom end will also point to the side of the marking ruler, which is convenient for the user to observe the tilt direction; however, during the construction process, since the casing is constructed by rotary drilling, the receiving ring is easily driven to rotate during the rotation of the casing, causing the channel steel to generate centrifugal force and slide away from the casing, resulting in inaccurate verticality detection and adjustment during construction.

[0004] Therefore, it is necessary to propose a device and method for adjusting the verticality of an engaging pile to solve the above problems. Summary of the Invention

[0008] Furthermore, the rack is internally threaded with a screw rod, and rotating the screw rod can move the screw rod along the sliding direction of the rack. The first end of the screw rod extending into the first through hole is rotatably connected to an extrusion block.

[0009] Furthermore, the second end of the screw away from the extrusion block is fixedly connected to the first gear, and the first gear is movably installed in the limiting cylinder.

Rotating the second gear ring can rotate multiple first gears so that multiple extrusion blocks move synchronously in a direction close to or away from the center of the sleeve.

[0010] Furthermore, the outer wall of the first gear ring is provided with a tooth shape, and a second gear meshing with the outer wall of the first gear ring is installed in the limiting rotation in the limiting cylinder, the diameter of the second gear is smaller than the diameter of the first gear ring, and an angle sensor for detecting the rotation angle of the second gear is installed in the limiting cylinder, and the second gear ring is provided with an arc-shaped notch for avoiding the second gear.

DETAILED DESCRIPTION

[0025] like Figures 1 to 3As shown, the present invention provides a device for adjusting the verticality of an engaging pile, comprising: a limiting cylinder 1, a first through hole 102 for a sleeve 4 to pass through is provided on the limiting cylinder 1, an annular cavity 101 arranged around the first through hole 102 is provided in the limiting cylinder 1, a first gear ring 2 is installed in the annular cavity 101 for limiting rotation, the inner wall of the first gear ring 2 is provided with a tooth shape, a plurality of groups of adjustment components 3 are circumferentially installed in the annular cavity 101 with the axis of the annular cavity 101 as the center, each group of adjustment components 3 includes two tooth columns 301 symmetrical about the center of the annular cavity 101, the tooth columns 301 are meshed with the inner wall of the first gear ring 2, and racks 302 capable of limiting sliding along the radial direction of the annular cavity 101 are installed on both sides of each of the tooth columns 301, One end of the rack 302 extends into the first through hole 102, and the rack 302 is engaged with the gear post 301. The first rack of the two racks 302 is arranged at the top of the gear post 301, and the second rack of the two racks 302 is arranged at the bottom of the gear post 301. Rotating the gear post 301 can cause the two racks 302 engaged on the same gear post 301 to approach or move away from the central axis of the annular cavity 101 along the radial direction of the annular cavity 101, respectively. The axis of the first rack engaged on the first gear post of the two gear posts 301 and the second rack engaged on the second gear post of the two gear posts 301 are located in the same plane, and the axis of the second rack engaged on the first gear post of the two gear posts 301 and the axis of the first rack engaged on the second gear post of the two gear posts 301 are located in the same plane.

[0026] In this solution, before the construction of the casing 4, the limit cylinder 1 is installed above the preset hole pile, and the ends of the multiple racks 302 extending to the first through hole 102 are on the same circumferential surface, and the first gear ring 2 is in the initial position; during the construction of the casing 4, after the casing 4 is passed through the first through hole 102, the multiple racks 302 extend to the ends of the first through hole 102 and fit into the outer wall of the casing 4. When the casing 4 is tilted, the casing 4 squeezes the first rack 302 along the tilting direction of the casing 4, so that the first rack 302 moves in a direction away from the axis of the annular cavity 101. The first gear ring 2 slides in the direction of the rotation direction, thereby driving the corresponding first gear column 301 to rotate, thereby driving the first gear ring 2 to rotate, thereby causing the second gear column 301 to rotate, and causing the second rack 302 on the second gear column 301 to slide in the direction close to the axis of the annular cavity 101. At this time, the first gear ring 2 changes from its initial position due to its rotation, so that the inclination of the sleeve 4 can be identified by the rotation of the first gear ring 2; by rotating the first gear ring 2 to return the first gear ring 2 to its initial position, the corresponding rack 302 can be made to slide to squeeze the sleeve 4 back to its initial position.

[0027] This solution can identify the tilt of the sleeve 4 by the rotation angle of the first gear ring 2, which is convenient for identifying the tilt state of the sleeve 4; by setting multiple groups of adjustment components 3, and the two gear columns 301 in each group of adjustment components 3 are symmetrically arranged, so that rotating the first gear ring 2 can cause the relatively arranged first rack and second rack to apply thrust to the sleeve 4 at the same time, the first rack and the second rack are respectively arranged on both sides of the central axis of the annular cavity 101, and the first rack and the second rack are staggered in the longitudinal direction to ensure that the center of the sleeve 4 will not shift after the sleeve 4 returns to its original position; avoid the center offset before and after the return caused by the sleeve 4 returning to its original position after being offset by only unilateral thrust, so as to ensure the accuracy of the vertical adjustment of the occlusal pile.

[0028] In one embodiment of the present invention, the rack 302 is internally threadedly connected to the screw 303. Rotating the screw 303 can move the screw 303 along the sliding direction of the rack 302. The first end of the screw 303 extending into the first through hole 102 is rotatably connected to the extrusion block 304.

[0029] In this solution, by rotating the screw 303, the extrusion block 304 can be moved closer to or away from the casing 4 in the radial direction of the annular cavity 101, so as to adjust the diameter of the circumferential surface formed by multiple extrusion blocks 304 to adapt to casings 4 of different diameters and facilitate the rotary drilling movement of the casing 4 during the construction process.

[0030] In one embodiment of the present invention, the second end of the screw 303 away from the extrusion block 304 is fixedly connected to the first gear 305, and the first gear 305 is movably installed in the limiting cylinder 1. The first gear 305 can rotate on its own and can slide in the radial direction of the annular cavity 101. A second gear ring 306 arranged around the first gear ring 2 is installed in the annular cavity 101 for limited rotation. The second gear ring 306 is arranged between the first rack and the second rack. The second gear ring 306 has teeth on the opposite side walls. The first gear 305 connected to the first rack is engaged with the top wall of the second gear ring 306, and the first gear 305 connected to the second rack is engaged with the bottom wall of the second gear ring 306. Rotating the second gear ring 306 can rotate multiple first gears 305 to make multiple extrusion blocks 304 move synchronously toward or away from the center of the sleeve 4.

[0031] In this solution, when the second gear ring 306 is rotated, the first gear 305 can be driven to rotate. Since the first gear 305 is fixedly connected to the screw 303, the screw 303 is rotated. When the screw 303 rotates, it slides in the radial direction of the annular cavity 101, thereby causing the first gear 305 to slide in the radial direction of the annular cavity 101. That is, when the second gear ring 306 is rotated, the first gear 305 can slide in the radial direction of the annular cavity 101 while the first gear 305 rotates. Since the first gear 305 connected to the first rack and the first gear 305 connected to the second rack are respectively meshed with the second gear ring 306, the second gear ring 306 can slide in the radial direction of the annular cavity 101. 06 on both sides, so that when the second gear ring 306 is rotated, the first gear on the first rack and the first gear on the second rack rotate in opposite directions, then by setting the thread directions of the screw 303 connected to the first rack and the screw 303 connected to the second rack to be opposite, it is possible to make the extrusion block 304 on the first rack and the extrusion block 304 on the second rack move in the same direction when the second gear ring 306 is rotated, that is, rotating the second gear ring 306 can make multiple extrusion blocks 304 move synchronously, thereby facilitating the adjustment of the diameter of the circumferential surface formed by the multiple extrusion blocks 304 to adapt to sleeves 4 of different diameters.

[0032] In one embodiment of the present invention, the outer wall of the first gear ring 2 is provided with a tooth shape, and a second gear 5 meshing with the outer wall of the first gear ring 2 is installed in the limiting rotation inside the limiting cylinder 1. The diameter of the second gear 5 is smaller than the diameter of the first gear ring 2. An angle sensor for detecting the rotation angle of the second gear 5 is installed in the limiting cylinder 1, and an arc-shaped notch 307 for avoiding the second gear 5 is provided on the second gear ring 306.

[0033] In this solution, a second gear 5 is provided, and the diameter of the second gear 5 is smaller than the diameter of the first gear ring 2, so that when the first gear ring 2 rotates and drives the second gear 5 to rotate, the angular displacement is increased, thereby improving the sensitivity of the angle sensor in identifying the rotation of the second gear 5, thereby improving the accuracy of the inclination judgment of the sleeve 4; an arc-shaped notch 307 is provided to provide avoidance space for the second gear 5, thereby ensuring the rationality of the structure; and a stopper extending into the arc-shaped notch 307 is provided on both sides of the second gear 5 on the limiting cylinder 1, so that when the second gear ring 306 rotates, the inner wall of the arc-shaped notch 307 can be against the stopper to avoid the second gear ring 306 rotating to interfere with the second gear 5, and by providing a stopper, the second gear ring 306 is limited in rotation to prevent the first gear 305 from disengaging from the second gear ring 306.

[0034] In one embodiment of the present invention, the adjusting device also includes a base 7, which is provided with a second through hole 701 for the sleeve 4 to pass through, and the diameter of the second through hole 701 is larger than the diameter of the first through hole 102, and the limiting cylinder 1 is installed on the base 7 through a support rod 8, and a plurality of driving mechanisms 9 for outputting linear motion are rotatably installed on the base 7, the output end of the driving mechanism 9 is fixedly connected to the support rod 8, and the support rod 8 is rotatably connected to the limiting cylinder 1, and the driving mechanism 9 includes but is not limited to a cylinder or an electric cylinder, and a plurality of V-shaped cavities 103 corresponding to the support rod 8 are circumferentially arranged in the limiting cylinder 1 with the axis of the limiting cylinder 1 as the center, and a ball 6 is provided in the V-shaped cavity 103, and a slide 601 is slidably installed on the two inclined bottom walls of the V-shaped cavity 103, and a spring 602 is connected between the slide 601 and the side wall of the V-shaped cavity 103, and a pressure sensor for detecting the pressure of the spring 602 is installed in the V-shaped cavity 103.

[0035] In this solution, when the limiting cylinder 1 is in a vertical state, the ball 6 in each V-shaped cavity 103 is located at the bottom of the V-shaped cavity 103, and the slides 601 on both sides of the ball 6 are in contact with the ball 6. At this time, the spring 602 is in a normal state, and the pressure of the spring 602 sensed by the pressure sensor returns to 0. When the limiting cylinder 1 tilts, the ball 6 slides in the tilting direction, thereby squeezing the slide 601 set along the tilting direction to deform the corresponding spring 602. The deformation of the spring 602 can be detected by the pressure sensor to judge the tilting state of the limiting cylinder 1; then the limiting cylinder 1 is adjusted to a vertical state through the driving mechanism. Among them, the V-shaped cavity 103 is located above the annular cavity 101, that is, the ball 6 is set at the top of the limiting cylinder 1 to increase the installation height of the ball 6, so that when the limiting cylinder 1 tilts, the sensitivity of judging the tilt of the limiting cylinder 1 can be improved.

[0036] This solution determines the tilt state of the limit cylinder 1 and uses a driving mechanism to adjust the limit cylinder 1 to a vertical state, thereby avoiding the influence of poor verticality of the occlusal pile caused by the installation tilt of the limit cylinder 1 due to uneven ground.

[0037] A method for adjusting a verticality adjustment device of an occlusal pile, comprising:

[0038] S1, vertical adjustment of the limiting cylinder 1: After the base 7 is installed on the ground, the driving mechanism is started to move the support rod 8 so that the pressure of the spring 602 sensed by the pressure sensor is 0, and the ball 6 is at the lowest end of the V-shaped cavity 103;

[0039] Among them, when the spring pressure on the left side of the ball 6 sensed by the pressure sensor changes, the driving mechanism on the limit cylinder 1 close to the ball 6 is activated to drive the support rod 8 to move upward, and the driving mechanism on the limit cylinder 1 away from the ball 6 is activated to drive the support rod 8 to retract until the spring pressure sensed by the pressure sensor is 0;

[0040] S2, vertical adjustment of the sleeve 4: When the sleeve 4 is in a vertical state, the multiple extrusion blocks 304 form a same circumferential surface, and the rotation angle of the second gear 5 sensed by the angle sensor is set to the initial value; when the sleeve 4 is tilted, the change in the value sensed by the angle sensor can be used to determine that the second gear 5 has rotated. At this time, the second gear 5 is rotated to return the value sensed by the angle sensor to the initial value.

[0041] In the installation process of the sleeve 4, after the sleeve 4 passes through the first through hole 102 and the second through hole 701, the second gear ring 306 is rotated so that the multiple first gears 305 meshing with the second gear ring 306 are rotated, so that the screw 303 is rotated, so that the multiple extrusion blocks 304 move toward the center of the sleeve 4 to clamp the sleeve 4, until the second gear ring 306 cannot rotate, and the rotation angle of the second gear sensed by the angle sensor is set to the initial value.

[0042] In this solution, before construction, the influence of uneven ground is avoided by adjusting the limit cylinder 1 to a vertical state; during construction, the verticality of the sleeve 4 can be adjusted by rotating the second gear 5, and the angle sensor can improve the recognition of the inclination of the sleeve 4 and the accuracy of the vertical adjustment of the sleeve 4; during the installation of the sleeve 4, the second gear ring 306 is rotated to make the multiple extrusion blocks 304 clamp the sleeve 4. In this process, the inclination of the sleeve 4 can be pre-adjusted, and when the second gear ring 306 cannot rotate, the sleeve 4 is in a vertical state.

[0043] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
