Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a micro pile steel pipe insertion positioning and sag limiting device. Background Art

[0002] Micropiles have been widely used in various construction projects, geological disaster control projects and special foundation reinforcement projects due to their significant advantages such as flexible construction, high bearing capacity and little impact on the surrounding environment. Especially in narrow spaces, complex geological conditions or areas sensitive to existing buildings, micropile construction has become a key technical means. Steel pipe insertion positioning and vertical limiting are the core links of micropile construction, which directly affect the construction quality of micropiles and the overall safety of the project.

[0003] Traditional micropile steel pipe insertion construction mostly relies on manual positioning and simple supporting equipment, and there are still some inconveniences in use. In the existing technology, simple tools and manual experience are usually used to determine the center position of the steel pipe. In complex geological environments or projects with extremely high positioning accuracy requirements, this method is difficult to ensure that the center of the steel pipe is accurately aligned with the design point, resulting in the micropile bearing performance cannot be fully utilized, affecting the safety and stability of the entire project structure. During the lowering of the steel pipe, the existing technology lacks a stable guiding mechanism. The steel pipe is prone to shaking under the action of its own weight and the external force of insertion, and it is difficult to stably lower it to the exact center of the pit, which increases the difficulty and risk of construction. Moreover, the existing technology has limited ability to adjust the position of the steel pipe. Once an offset occurs, it is difficult to make accurate and convenient adjustments. Re-construction or remedial measures can only be taken, increasing construction costs and time. Summary of the Invention

[0013] Furthermore, a coupling block is fixedly installed on the bottom surface of the side frame body, a dual-axis motor is arranged inside the coupling block, a rotating shaft is arranged on both output ends of the dual-axis motor, a rotating plate is arranged at the other end of the rotating shaft, and a bottom laser light is arranged on the bottom surface of the rotating plate body.

[0014] Furthermore, a bottom frame is provided on the bottom surface of the rotating plate body, a force-bearing bottom frame is provided on one side surface of the bottom frame, and a plurality of supporting rollers are provided on the upper surface of the force-bearing bottom frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this solution, a limiting component is provided, and the servo motor drives the meshing screw to rotate, driving the meshing sliding block to move. The elastic connecting belt is used to clamp the steel pipe body with the fitting side plate. The reel controls the side frame to descend together with the steel pipe body into the pile pit, thereby achieving precise positioning and stable descent of the steel pipe body in the pile pit, effectively avoiding shaking and deviation of the steel pipe body during the descent process, ensuring that the steel pipe body can be accurately installed at the exact point in the center of the pit, improving the construction accuracy and quality, and reducing the construction risks and costs caused by position deviation.

[0017] 2. In this solution, by providing a detection component, the flip cover can be flipped over to cover the top of the feed pipe, and the auxiliary lens on its bottom can cooperate with the total station to locate the center point of the micro pile. The camera on the upper surface observes the laser crosshairs projected by the bottom laser light at the bottom of the pit from the center of the steel pipe body through the center of the feed pipe, so that the staff can intuitively judge whether the steel pipe body is aligned with the target point. When the crosshairs are not aligned, the staff can remotely control the device to drive the four control motors to rotate to different degrees, adjust the rotation amplitude of the rotating support, and thus make small adjustments to one end of the steel pipe body. At the same time, the four side laser lights are used to observe whether the steel pipe body is offset. If one end of the bottom surface of the steel pipe body does not block the side laser light spot, it indicates that there is no offset. If offset occurs, it can be adjusted in time by controlling the rotating support. This component realizes real-time and accurate detection and adjustment of the position of the steel pipe body, so that the staff can promptly discover and correct the position deviation of the steel pipe body and ensure the accuracy of the installation position of the steel pipe body.

[0018] 3. In this solution, a support assembly is provided, and the output shaft of the internal electric rod extends to push the drive motor and the rotating pin to move downward. The drive motor drives the rotating pin to rotate at high speed and insert it into the ground. At the same time, the rotating connecting plates on both sides are flipped to make the load-bearing rollers add weight to the support legs to increase stability. The device forms a stable support system through the support legs, top frame and rotating pins. The support frame further enhances the stability of the support legs to prevent shaking or tilting. This component provides stable and reliable support for the entire device, ensures the stability of the device during construction, enables the device to be accurately positioned and operated, and avoids the positioning accuracy and construction quality of the steel pipe body affected by shaking or tilting of the device, thereby improving the safety and reliability of construction.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1 to 8 A micro pile steel pipe insertion positioning and sag limiting device, comprising:

[0031] The center limiting sleeve 1 and the side surface of the center limiting sleeve 1 are provided with a support assembly, which includes: four storage tubes 9, which are respectively provided on the four side surfaces of the center limiting sleeve 1, and a top frame 2 is provided on the end of the storage tube 9 away from the center limiting sleeve 1. The support assembly also includes four support legs 3, and the surfaces of the four support legs 3 are also provided with a support frame 5 that cooperates with the top frame 2. The side surfaces of the support legs 3 are provided with side connecting blocks 34, and each side connecting block 34 is connected to one end of the two top frames 2. An internal electric rod 35 is provided inside the support leg 3, and a drive motor 36 is provided at the end of the output shaft of the internal electric rod 35. A rotating pin 37 is provided at the end of the output shaft of the drive motor 36. An additional disc 38 is also provided on the upper surface of the rotating pin 37. A rotatable rotating connecting plate 39 is provided on both side surfaces of the additional disc 38. A shaft body is provided at the connection between the rotating connecting plate 39 and the additional disc 38, and a load-bearing roller 40 is provided on one side surface of the rotating connecting plate 39;

[0032] When in use, the staff first uses the total station to mark the exact point on the bottom surface of the pile pit. Then, the staff moves the device to the upper surface of the pile hole, and locates the center point of the micro pile through the cooperation of the auxiliary lens 12 and the total station, and fine-tunes the position of the device to align the center position of the device with the center point of the micro pile. Then, the staff sends a signal through the external control device to drive the internal electric rod 35 to start, so that the output shaft of the internal electric rod 35 extends, pushing the drive motor 36 and the rotating pin 37 to move downward. At the same time, the drive motor 36 is also started, driving the rotating pin 37 to rotate at high speed. During the rotation, the rotating pin 37 gradually inserts into the ground by using its conical head and rotational torque. As the rotating pin 37 is inserted, the staff flips the two load-bearing rollers 40 by rotating the connecting plates 39 on both sides. At this time, the load-bearing rollers 40 can add weight to the support legs 3 to increase stability. When the side surfaces of the load-bearing rollers 40 come into contact with the ground, the device forms a stable support system through the support legs 3, the top frame 2 and the rotating pin 37. During the support process of the device, the support frame 5 further enhances the stability of the support legs 3, prevents the support legs 3 from shaking or tilting, and ensures stable support of the device.

[0033] The lower surface of the center limiting sleeve 1 is also provided with a limiting component, which includes: four servo motors 8, the four servo motors 8 are respectively located at one end of the four storage tubes 9, and the output end of the servo motor 8 is provided with an engaging screw 13, the engaging screw 13 is located inside the storage tube 9, the surface of the engaging screw 13 is engaged with an engaging sliding block 14, and the bottom surface of the engaging sliding block 14 is provided with a reel 15, the interior of the reel 15 is reeled with a connecting rope 20, one end of the connecting rope 20 is provided with a connecting block 16, and the bottom surface of the connecting block 16 is provided with a side frame 11, one side surface of the side frame 11 is provided with a fitting side plate 42, and an elastic connecting belt 41 is connected between the four fitting side plates 42, and a rotatable rotating support foot 18 is provided on the side surface of the side frame 11 away from the fitting side plate 42, and a control motor 17 is provided on the side surface of the side frame 11, and the output shaft of the control motor 17 is connected to one end of the rotating support foot 18. A limiting block 19 is provided to cooperate with the rotating support foot 18, a slidable sliding inner plate 22 is provided inside the rotating support foot 18, and an inner groove 23 is provided on the inner side surface of the rotating support foot 18 to cooperate with the sliding inner plate 22, a connecting spring 24 is connected between the sliding inner plate 22 and the inner side surface of the rotating support foot 18, a small telescopic rod 25 is provided on the inner side surface of the rotating support foot 18, and a contact roller 21 is provided at one end of the sliding inner plate 22, and a coupling block 26 is fixedly installed on the bottom surface of the side frame body 11, a dual-axis motor is provided inside the coupling block 26, and a rotating shaft 27 is provided on both output ends of the dual-axis motor, and a rotating plate body 28 is provided at the other end of the rotating shaft 27, and a bottom laser light 29 is provided on the bottom surface of the rotating plate body 28, and a bottom frame body 10 is also provided on the bottom surface of the rotating plate body 28, and a force-bearing base frame 30 is provided on one side surface of the bottom frame body 10, and a plurality of supporting rollers 31 are provided on the upper surface of the force-bearing base frame 30;

[0034] After the equipment is erected, the staff flips the flip cover 7 above the feed pipe 4 to expose the entrance above the feed pipe 4, and then puts the steel pipe body 6 in from the top of the feed pipe 4 through equipment such as a crane. After one end of the steel pipe body 6 enters the interior of the feed pipe 4, it is mounted on top of multiple force-bearing base frames 30 below the center of the center limit sleeve 1. The bottom surface of one end of the steel pipe body 6 contacts multiple support rollers 31 above the force-bearing base frame 30. At this time, the servo motor 8 is started under the signal drive of the staff, driving the meshing screw 13 to rotate, and the four meshing sliding blocks 14 all move toward the direction of the center limit sleeve 1 under the meshing state of the meshing screw 13, and with the convergence effect of the elastic connecting belt 41, the servo motor 8 is used to rotate. The four fitting side plates 42 clamp the side surface of the steel pipe body 6, and then the reel 15 pays out the line under the control of the staff, so that the side frame body 11 and the steel pipe body 6 are lowered together and enter the interior of the pile pit. After entering the interior of the pile pit, the control motor 17 is rotated under the drive of the staff to rotate the rotating support leg 18. The contact roller 21 at one end of the rotating support leg 18 fits the inner side surface of the pit and slides on the inner side wall of the pile pit when the steel pipe body 6 descends. At this time, the output shaft end of the small telescopic rod 25 inside the rotating support leg 18 does not contact one end of the sliding inner plate 22. The rotating support leg 18 and the sliding inner plate 22 are connected by a connecting spring 24. When the contact roller 21 slides on the inner wall of the pile pit When the steel pipe body 6 is completely inserted into the feed pipe 4, the small telescopic rod 25 extends and contacts one end of the sliding inner plate 22 through the end of the output shaft, and produces a restriction effect on both sides of the pit wall, so that the sliding inner plate 22 will not move under the action of the connecting spring 24. At this moment, the steel pipe body 6 is fixed in position, and then the staff can flip the flip cover 7 to allow the detection component to detect the steel pipe body. The position of the steel pipe body 6 is detected (here, the deviation of the steel pipe body 6 to the right side of the accurate point is taken as an example. At this time, the control motor 17 on the right side can be controlled to rotate in the reverse direction to make the rotating support leg 18 on the right side expand a distance, and the control motor 17 on the left side rotates forward to make the rotating support leg 18 on the left side converge a distance. Under the action of the inner wall of the pile pit, one end of the steel pipe body 6 can be moved to the left and aligned with the accurate point). In this way, the steel pipe body 6 can be installed at the accurate point. When the crosshairs are aligned with the mark on the accurate point, it can be determined that the position is correct. Subsequently, the staff drives the dual-axis motor inside the joint block 26 to rotate through the signal, and drives the rotating plate 28 to rotate through the rotating shaft 27. At this time,As the rotating plate 28 rotates, the upper surface of the load-bearing base frame 30 gradually loses contact with one end of the steel pipe body 6. At this time, the steel pipe body 6 is completely fixed by the lifting rope above. Subsequently, the steel pipe body 6 is lowered and contacts the ground under the action of the lifting machinery. After contact, one end of the steel pipe body 6 can be hammered from above the feed pipe 4 to fix it on the ground. Finally, the rotating support leg 18 rotates and converges under the drive of the control motor 17, and finally stops after being restricted by the limit block 19. The servo motor 8 rotates again under the drive of the staff, driving the meshing sliding block 14 to move, so that the four contact side plates 42 are away from the surface of the steel pipe body 6. Subsequently, the reel 15 is retracted and the side frame body 11 is pulled out of the pit. Subsequently, the staff can use the internal electric rod 35 to pull the rotating pin 37 out of the ground, and rotate the load-bearing roller 40 to make contact with the ground again and move the equipment.

[0035] A detection assembly is provided on the upper surface of the center limiting sleeve 1, and the detection assembly includes: a feed pipe 4, which is fixedly mounted on the upper surface of the center limiting sleeve 1, a steel pipe body 6 is provided at the center of the feed pipe 4, a rotatable flip cover 7 is provided on one side surface of the feed pipe 4, a connecting shaft is provided at the connection between the flip cover 7 and the feed pipe 4, an auxiliary lens 12 is provided on the bottom surface of the flip cover 7, a camera 32 is provided at the center of the upper surface of the flip cover 7, and a side laser light 33 is also provided on the upper surface of the flip cover 7;

[0036] The staff can flip the flip cover 7 and put it back on the top of the feeding pipe 4. Because the size of the flip cover 7 is slightly smaller than the feeding pipe 4, there is still a gap on the edge of the flip cover 7 when the flip cover 7 is covered on the top of the feeding pipe 4, which is convenient for the normal operation of the lifting rope. The four bottom laser lights 29 project a laser crosshair on the surface of the pit bottom. The staff can observe the crosshair from the center of the steel pipe body 6 through the display screen of the external connection device and the camera 32 located on the bottom surface of the flip cover 7 at this time. When the crosshair is not aligned with the target After the point is set, the staff can use the control device to drive the four control motors 17 to rotate to different degrees. By controlling the rotation amplitude of the rotating support leg 18 and adjusting the force in the pit wall, one end of the steel pipe body 6 can be adjusted slightly, and the four side laser lamps 33 are used to observe whether the steel pipe body 6 is offset. When the four side laser lamps 33 are irradiated on the surface of the steel pipe body 6, if one end of the bottom surface of the steel pipe body 6 does not produce an obstruction of the light spot, it is in an unobstructed state. If an offset occurs, it can be adjusted by controlling the rotation amplitude of the rotating support leg 18.

[0037] The working principle of the present invention is:

[0038] When in use, the staff first uses the total station to mark the exact point on the bottom surface of the pile pit. Then, the staff moves the device to the upper surface of the pile hole, and locates the center point of the micro pile through the cooperation of the auxiliary lens 12 and the total station, and fine-tunes the position of the device to align the center position of the device with the center point of the micro pile. Then, the staff sends a signal through the external control device to drive the internal electric rod 35 to start, so that the output shaft of the internal electric rod 35 extends, pushing the drive motor 36 and the rotating pin 37 to move downward. At the same time, the drive motor 36 is also started, driving the rotating pin 37 to rotate at high speed. During the rotation process, the rotating pin 37 gradually inserts into the ground by using its conical head and rotational torque. As the rotating pin 37 is inserted, the staff flips the two load-bearing rollers 40 by rotating the connecting plates 39 on both sides. At this time, the load-bearing rollers 40 can add weight to the support legs 3 to increase stability. When the side surfaces of the load-bearing rollers 40 come into contact with the ground, the device forms a stable support system through the support legs 3, the top frame 2 and the rotating pin 37. During the support process of the device, the support frame 5 further enhances the stability of the support legs 3, prevents the support legs 3 from shaking or tilting, and ensures the stable support of the device.

[0039] After the equipment is erected, the staff will flip the flip cover 7 above the feed pipe 4 to expose the entrance above the feed pipe 4. Then, the steel pipe body 6 is put in from the top of the feed pipe 4 through a crane or other equipment. After one end of the steel pipe body 6 enters the interior of the feed pipe 4, it is carried above the multiple force-bearing base frames 30 below the center of the center limiting sleeve 1. The bottom surface of one end of the steel pipe body 6 contacts the multiple support rollers 31 above the force-bearing base frames 30. At this time, the servo motor 8 is started under the signal drive of the staff, driving the meshing The engaging screw 13 rotates, and the four engaging sliding blocks 14 all move toward the direction of the center limiting sleeve 1 under the meshing state of the engaging screw 13. Under the tightening effect of the elastic connecting belt 41, the side surface of the steel pipe body 6 is clamped by the four fitting side plates 42. Subsequently, the reel 15 pays off the line under the control of the staff, so that the side frame body 11 and the steel pipe body 6 are lowered together and enter the interior of the pile pit. After entering the interior of the pile pit, the control motor 17 is driven by the staff to rotate, so that the rotating support leg 18 moves forward. The contact roller 21 at one end of the rotating support leg 18 is in contact with the inner side surface of the pit and slides on the inner side wall of the pile pit when the steel pipe body 6 descends. At this time, the output shaft end of the small telescopic rod 25 inside the rotating support leg 18 does not contact one end of the sliding inner plate 22. The rotating support leg 18 and the sliding inner plate 22 are connected by a connecting spring 24. When the contact roller 21 slides on the inner wall of the pile pit, if it encounters unevenness, the connecting spring 24 will contract, driving the contact roller 21 to avoid it. The four contact rollers 21 act on the side surfaces of the pile pit, so that the steel pipe body 6 can avoid shaking during the descent process and can be placed in a more stable state at the accurate point in the center of the pit. After the steel pipe body 6 has completely entered the interior of the feed pipe 4, the small telescopic rod 25 extends and contacts one end of the sliding inner plate 22 through the end of the output shaft, and exerts a restraining effect on both sides through the pit wall, so that the sliding inner plate 22 will not move under the action of the connecting spring 24. At this point, the steel pipe body 6 is completely fixed in position.

[0040] The staff can flip the flip cover 7 and put it back on the top of the feeding pipe 4. Because the size of the flip cover 7 is slightly smaller than the feeding pipe 4, there is still a gap on the edge of the flip cover 7 when the flip cover 7 is covered on the top of the feeding pipe 4, which is convenient for the normal operation of the lifting rope. The four bottom laser lights 29 are used to project a laser crosshair on the surface of the pit bottom. The staff can observe the crosshair from the center of the steel pipe body 6 through the display screen of the external connection device and the camera 32 located on the bottom surface of the flip cover 7 at this time. When the crosshair is not aligned with the target point, the staff can drive the control device to turn on the flip cover 7. The four control motors 17 rotate to different degrees, and by controlling the rotation amplitude of the rotating support leg 18 to adjust the force in the pit wall, one end of the steel pipe body 6 can be adjusted slightly (here, taking the steel pipe body 6 deviating to the right side of the accurate point as an example, at this time, the control motor 17 on the right side can be controlled to rotate in the reverse direction to make the rotating support leg 18 on the right side expand a distance, while the control motor 17 on the left side rotates forward to make the rotating support leg 18 on the left side converge a distance. Under the action of the inner wall of the pile pit, one end of the steel pipe body 6 can be moved to the left and aligned with the accurate point), so that the steel pipe body 6 can be adjusted to the right side. The main body 6 can be installed at the exact point. When the crosshairs are aligned with the mark on the exact point, it can be determined that the position is correct. Subsequently, the staff drives the dual-axis motor inside the coupling block 26 to rotate through the signal, and drives the rotating plate 28 to rotate through the rotating shaft 27. At this time, the upper surface of the force-bearing base 30 gradually loses the contact effect with one end of the steel pipe main body 6 as the rotating plate 28 rotates. At this time, the steel pipe main body 6 is completely fixed by the lifting rope above. Subsequently, the steel pipe main body 6 is lowered under the action of the lifting machinery and contacts the ground. After contact, the steel pipe main body can be lifted from above the feed pipe 4. One end of the body 6 is hammered to fix it on the ground. Finally, the rotating support leg 18 rotates and converges under the drive of the control motor 17, and finally stops after being restricted by the limiting block 19. The servo motor 8 rotates again under the drive of the staff, driving the meshing sliding block 14 to move, so that the four fitting side plates 42 are away from the surface of the steel pipe body 6. Then, the winder 15 is tightened and the side frame body 11 is pulled out of the pit. Then, the staff can use the internal electric rod 35 to pull the rotating pin 37 out of the ground, and rotate it to make the ground of the load-bearing roller 40 contact the equipment again, and move the equipment.

[0041] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
