Description

Technical Field

[0001] This invention relates to the field of pipe pile testing technology, specifically a verticality testing instrument for deep foundation pit pipe piles. Background Technology

[0002] Deep foundation pipe piles are prefabricated pile foundation components, usually circular, made of high-strength concrete or steel. They are driven into the ground to a certain depth through methods such as driving and static pressure, serving as the foundation of buildings or other structures, bearing various loads from the superstructure and transferring them to the deep bearing layer.

[0003] Before driving pipe piles into the ground, it is necessary to test their verticality. The conventional method requires multiple construction workers to use handheld laser testing equipment to measure the verticality of the pipe piles, which makes the entire testing operation difficult and requires the cooperation of multiple operators. Therefore, it is necessary to improve the method. Summary of the Invention

[0004] This invention provides a verticality testing instrument for deep foundation pit pipe piles, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The clamping mechanism includes a clamping side plate rotatably connected to the end of the support beam. A traveling roller is rotatably connected to the side of the support beam. A clamping roller that rotates synchronously with the traveling roller is located on the side of the clamping side plate near the traveling roller. The lifting and adjusting mechanism includes a through hole in the middle of the support beam. A crossbeam is located in the middle of the through hole. A fixed rod is located on the crossbeam and connected through the through hole. A lifting drive wheel that drives the traveling roller to rotate is located on the side of the fixed rod near the traveling roller. A support plate is located on the side of the support beam away from the traveling roller. A winding wheel is located on the support plate. A suspension rope is wound around the outside of the winding wheel. A weight is located at the free end of the suspension rope. A rotation drive assembly that drives the lifting drive wheel and the winding wheel to rotate synchronously is located on the side of the fixed rod away from the traveling roller. The winding wheel and the traveling roller have the same linear velocity. When the traveling roller moves along the side wall of the pipe pile in a direction away from the ground, the winding wheel releases the suspension rope.

[0007] In a preferred embodiment of the present invention, a synchronous rotation assembly for transmission is provided between the traveling roller and the clamping roller, and a clamping drive assembly for driving the two clamping side plates to rotate synchronously in opposite directions is provided on the support beam. The clamping drive assembly includes a slide groove provided on the support beam, a first slider slidably connected to the slide groove, one end of a first top plate rotatably connected to the side of the first slider, and a vertical rod fixedly connected to the end of the clamping side plate rotatably connected to the other end of the first top plate. A first fixing plate fixedly connected to the support beam is provided at the end of the slide groove, and a lead screw threadedly connected to the first slider is rotatably connected to the first fixing plate.

[0008] In a preferred embodiment of the present invention, the synchronous rotation assembly includes a sliding sleeve disposed between the traveling roller and the clamping roller. Extending rods are slidably connected to both ends of the sliding sleeve, and the ends of the extending rods are connected to the ends of either the traveling roller or the clamping roller via universal joints. A second fixing plate is provided on the side of the support beam, and a sliding rod is fixedly connected to the second fixing plate. A second slider is slidably connected to the sliding rod, and a buffer spring is provided between the second slider and the second fixing plate. One end of a second top plate is rotatably connected to the side of the second slider, and the other end of the second top plate is rotatably connected to a fixed seat fixedly connected to the sliding sleeve.

[0009] As a preferred embodiment of the present invention, the rotary drive assembly includes an extension beam disposed on the side of the through hole, an extension beam having a rotary drive wheel rotatably connected to its end, which rotates synchronously with the winding wheel, a first fixing block being disposed at the end of the fixing rod away from the traveling roller, a rotary wheel being rotatably connected to the middle of the first fixing block, a rotary belt for driving the rotary wheel to rotate being sleeved on the outside of the rotary wheel, a first pulley being disposed at the end of the rotary wheel, the first pulley driving the second pulley and the third pulley to rotate simultaneously via a synchronous belt, the second pulley being coaxially connected to the rotary drive wheel, and the third pulley being coaxially connected to the lifting drive wheel.

[0010] As a preferred embodiment of the present invention, a top rod is slidably connected to the support plate, a third fixing block is provided at the end of the top rod, the third fixing block is rotatably connected to the winding wheel, and a clamping spring is provided between the top rod and the support plate to drive the top rod to move in the direction of the rotating drive wheel.

[0011] In a preferred embodiment of the present invention, the outer side of the rotating wheel is provided with a limiting tooth, and a suspension frame is provided on the side of the first fixed block. The suspension frame is slidably connected to a limiting slide rod, and the end of the limiting slide rod is provided with a limiting head that cooperates with the limiting tooth. A limiting spring is provided between the limiting head and the suspension frame to drive the limiting head to move toward the limiting tooth. Stop bars are provided on both sides of the first fixed block to prevent the rotating belt from disengaging from the rotating wheel.

[0012] The present invention has the following advantages:

[0013] By setting adjustable clamping rollers and traveling rollers that rotate synchronously, the detector can fix the pipe pile and actively adjust the tilt angle. As the detector moves upward along the pipe pile, the winding wheel continuously releases the same length of suspension rope, allowing the pipe pile to be compared with the suspension rope that keeps it vertical, thus completing the verticality detection. The entire detector does not require an additional power supply and can be operated by a single person, making it convenient to use. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In one embodiment, see Figures 1-11 A verticality testing instrument for deep foundation pit pipe piles includes a support beam 1, a clamping mechanism 2, and a lifting and adjusting mechanism 3;

[0029] The clamping mechanism 2 includes a clamping side plate 7 rotatably connected to the end of the support beam 1. The support beam 1 is arranged in a front-to-back orientation. A first support frame 4 is provided on the left side of the support beam 1. The first support frame 4 is rotatably connected to a traveling roller 5 arranged in a front-to-back orientation. The right side of the clamping side plate 7 is rotatably connected to both ends of the support beam 1. The two clamping side plates 7 are symmetrically arranged with respect to the center of the support beam 1. A second support frame 6 is provided on the side of the clamping side plate 7 near the traveling roller 5. The second support frame 6 is rotatably connected to a clamping roller 8 that is in the same plane as the traveling roller 5. The side walls of the traveling roller 5 and the clamping roller 8 are both concave arc surfaces, which allows the clamping roller 8 and the traveling roller 5 to better contact the side wall of the pipe pile. A rubber layer can be provided on the side walls of the clamping roller 8 and the traveling roller 5 to increase friction.

[0030] The lifting adjustment mechanism 3 includes a through hole 26 located in the middle of the support beam 1. The through hole 26 is oriented front-to-back, allowing the left and right sides of the support beam 1 to pass through it. A crossbeam 27 oriented front-to-back is located in the middle of the through hole 26. Fixed rods 29 oriented left-to-right are fixedly connected to the front and rear sides of the crossbeam 27. A second fixed block 41 is fixedly connected to the left end of the fixed rod 29. A lifting drive wheel 28 is rotatably connected to the middle of the second fixed block 41. The lifting drive wheel 28 is in close contact with the traveling roller 5, so when the lifting drive wheel 28 rotates, it can drive the traveling roller 5 to rotate. A support plate 30 is located below the right side of the support beam 1. A winding wheel 31 oriented front-to-back is located above the support plate 30. A suspension rope 32 is wound around the outside of the wheel 31. A weight 33 is installed at the free end of the suspension rope 32. The weight 33 is subjected to gravity, which keeps the suspension rope 32 in a vertical downward state. The verticality of the pipe pile is detected by comparing the suspension rope 32 with the pipe pile. A rotary drive assembly 34 is installed at the right end of the fixed rod 29. The rotary drive assembly 34 can drive the winding wheel 31 and the lifting drive wheel 28 to rotate synchronously, and make the linear velocity of the outer side of the winding wheel 31 and the traveling roller 5 the same. Therefore, when the traveling roller 5 moves upward along the side wall of the pipe pile, the winding wheel 31 will adaptively release the suspension rope 32. The released suspension rope 32 is the same as the upward distance, so that the weight 33 is always at the bottom.

[0031] In one embodiment, a synchronous rotation component 9 is provided between the traveling roller 5 and the clamping roller 8. The synchronous rotation component 9 realizes the effect of power transmission, so that the traveling roller 5 can drive the two clamping rollers 8 to rotate synchronously. Furthermore, a clamping drive component 10 is provided above the support beam 1. The clamping drive component 10 can drive the two clamping side plates 7 to rotate synchronously in opposite directions, so that the two clamping rollers 8 can be clamped on the front and rear sides of the pipe pile, thereby achieving the effect of fixing the verticality detector to the pipe pile.

[0032] In one embodiment, the clamping drive assembly 10 includes a slide groove 12 disposed on the upper surface of the support beam 1. The slide groove 12 is arranged in a front-back orientation. Both the front and rear ends of the slide groove 12 are slidably connected to first sliders 14. The right side of the first slider 14 is rotatably connected to the left end of the first top plate 15. The right end of the first top plate 15 is rotatably connected to the upright rod 16. The lower end of the upright rod 16 is fixedly connected to the right end of the upper surface of the clamping side plate 7. Both the front and rear ends of the slide groove 12 are provided with first fixing plates 11 fixedly connected to the support beam 1. The middle part of the first fixing plate 11 is rotatably connected to the front and rear ends of the lead screw 13. The front and rear sides of the lead screw 13 are provided with threads of opposite directions. The front and rear sides of the lead screw 13 are respectively threaded to the front and rear first sliders 14. Therefore, when the lead screw 13 rotates, the front and rear first sliders 14 separate or move closer to each other, thereby causing the front and rear clamping side plates 7 to rotate closer or further apart, achieving the clamping drive effect.

[0033] In one embodiment, the synchronous rotation assembly 9 includes a sliding sleeve 23 disposed between the traveling roller 5 and the clamping roller 8. Extending rods 24 are slidably connected to both the front and rear sides of the sliding sleeve 23. A spring is disposed between the two extending rods 24 inside the sliding sleeve 23. A universal connector 25 is disposed at the end of the extending rod 24 away from the sliding sleeve 23. The two universal connectors 25 are respectively connected to the ends of the clamping roller 8 and the traveling roller 5. Therefore, when the traveling roller 5 rotates, it drives the sliding sleeve 23 and the extending rods 24 to rotate through the universal connectors 25. The extending rods 24 then drive the clamping roller 8 to rotate through the universal connectors 25. During clamping, the angle between the clamping roller 8 and the traveling roller 5 changes. At this time, the extending rods 24 move inside the sliding sleeve 23, ensuring that the universal connectors 25 always maintain the effect of power transmission. To ensure the stability of the sliding sleeve 23, a second fixing plate 17 is provided at both ends of the left side of the extended beam 53. The second fixing plate 17 is fixedly connected to a sliding rod 18 arranged in a front-back orientation. A second slider 20 is slidably connected to the middle of the sliding rod 18. The left side of the second slider 20 is rotatably connected to the right end of the second top plate 21. The left end of the second top plate 21 is rotatably connected to the right side of the fixing seat 22. The middle of the fixing seat 22 is fixedly connected to the middle of the sliding sleeve 23, thereby keeping the sliding sleeve 23 in a horizontal state during operation. A buffer spring 19 is provided between the second fixing plate 17 and the second slider 20 to prevent the sliding sleeve 23 from shaking.

[0034] In one embodiment, the rotary drive assembly 34 includes protruding beams 53 disposed on the front and rear sides of the lower side of the through hole 26. The right end of the protruding beams 53 is rotatably connected to a rotary drive wheel 40 arranged in a front-rear orientation. The rotary drive wheel 40 presses on top of the winding wheel 31. Therefore, when the rotary drive wheel 40 rotates, the winding wheel 31 will rotate accordingly, thereby achieving the effect of releasing the suspension rope 32. A first fixing block 35 is fixedly connected to the right end of the fixing rod 29. The middle of the two first fixing blocks 35 is rotatably connected to the front and rear sides of the rotary wheel 36. The middle of the rotary wheel 36 is recessed, and the annular rotating belt 37 is sleeved on the outside of the rotary wheel 36. Stop bars 49 are provided on the left and right sides of the rotary wheel 36 to prevent the rotating belt 37 from moving. The rotating wheel 36 becomes loose from the recessed part, so after pulling the rotating belt 37 down, the rotating belt 37 will wrap around the top of the rotating wheel 36. At this time, when the rotating belt 37 rotates, the rotating wheel 36 will also rotate accordingly. First pulleys 38 are set at both the front and rear ends of the rotating wheel 36. The first pulleys 38 drive the second pulley 39 and the third pulley 42 to rotate simultaneously through the synchronous belt 43. The second pulley 39 is fixed at both the front and rear ends of the rotating drive wheel 40, and the third pulley 42 is fixed at both the front and rear ends of the lifting drive wheel 28. Therefore, when the rotating wheel 36 rotates, the lifting drive wheel 28 and the rotating drive wheel 40 will rotate synchronously. This realizes that when the traveling roller 5 drives the detector to move up and down, the winding wheel 31 will synchronously retract or release the suspension rope 32.

[0035] In one embodiment, a vertically arranged top rod 52 is slidably connected to the right end of the support plate 30. The upper end of the top rod 52 is fixedly connected to a third fixing block 50. The third fixing block 50 is rotatably connected to the front and rear sides of the winding wheel 31. A limiting plate is provided at the lower end of the top rod 52. A tightening spring 51 is provided between the limiting plate and the support plate 30. The tightening spring 51 is sleeved on the outside of the top rod 52 and pushes the top rod 52 upward, so that the winding wheel 31 is pressed against the outside of the rotating drive wheel 40. When the suspension rope 32 outside the winding wheel 31 is continuously released, the diameter of the suspension rope 32 wrapped by the suspension rope 32 will decrease. At this time, the winding wheel 31 will move upward adaptively, so that the rotating drive wheel 40 will always drive the winding wheel 31 to rotate. Even if the diameter of the suspension rope 32 wrapped outside decreases, the linear velocity outside the winding wheel 31 will remain stable, so that the release speed of the suspension rope 32 remains stable.

[0036] In one embodiment, limiting teeth 44 that rotate synchronously with the rotating wheel 36 are provided on both the front and rear sides of the rotating wheel 36. A suspension frame 47 is provided on the upper surface of the first fixed block 35. The suspension frame 47 is slidably connected to a vertically arranged limiting slide rod 48. The lower end of the limiting slide rod 48 is fixedly connected to a limiting head 45 that cooperates with the limiting teeth 44. A limiting spring 46 is provided between the suspension frame 47 and the limiting head 45. The limiting spring 46 is sleeved on the outside of the limiting slide rod 48. The limiting spring 46 will push the limiting head 45 downward and press it against the outside of the limiting teeth 44. Therefore, when the rotating wheel 36 rotates with the rotating belt 37, the limiting head 45 will move up and down. However, when the rotating belt 37 is disengaged from the rotating wheel 36, the limiting head 45 will press against the limiting teeth 44, so that the rotating wheel 36 will not rotate on its own. Therefore, when the detector moves to a higher position, the detector will not fall due to its own weight.

[0037] In this embodiment, the pipe pile is vertically lifted by hoisting equipment and the lower end of the pipe pile is placed at the position where it needs to be installed. At this time, the verticality measuring instrument is installed.

[0038] Take out the testing instrument and place the support beam 1 facing forward and backward on the right side of the pipe pile. Rotate the screw 13, which drives the two clamping side plates 7 to move closer to each other, so that the clamping roller 8 and the traveling roller 5 are clamped on the side wall of the pipe pile respectively. As the clamping roller 8 is tightened, the two clamping rollers 8 and the traveling roller 5 achieve an automatic leveling effect. That is to say, when the clamping roller 8 can no longer move, the clamping roller 8 and the traveling roller 5 are both in a state perpendicular to the side wall of the pipe pile. At this time, the clamping roller 8 is located on the left side of the pipe pile, so that the testing instrument will not be released from the right side of the pipe pile.

[0039] The operator pulls down the rotating belt 37, which wraps around the rotating wheel 36. The rotating belt 37 drives the rotating wheel 36 to rotate, causing the lifting drive wheel 28 and the rotating drive wheel 40 to rotate synchronously. The lifting drive wheel 28 drives the detector to move upward along the side wall of the pipe pile through the traveling roller 5. The rotating drive wheel 40 drives the winding wheel 31 to release the suspension rope 32. When the detector moves to the height of the pipe pile, the suspension rope 32 is in a vertical state under the action of the weight of the counterweight 33. By comparing the angle between the suspension rope 32 and the pipe pile itself, the pipe pile is adjusted to keep it in a vertical state.

[0040] Pressure is applied to the upper end of the pipe pile by the pressure-applying device, causing the pipe pile to slowly insert into the ground. During the initial insertion, the angle between the suspension rope 32 and the pipe pile is continuously compared to ensure that the pipe pile remains vertical. When the weight 33 contacts the ground, the pipe pile has also inserted a certain distance into the ground and will no longer deflect. At this time, the rotating belt 37 can drive the rotating wheel 36 to rotate in the opposite direction, so that the traveling roller 5 can drive the detector to move downward along the pipe pile. At the same time, the winding wheel 31 continuously winds the suspension rope 32. When the detector moves to the bottom, the screw 13 can be rotated in the opposite direction to disengage the clamping roller 8 from the side wall of the pipe pile. At this time, the detector can be removed, and the pipe pile can be pressured again to allow the pipe pile to be fully inserted into the ground.

[0041] This invention relates to a verticality testing instrument for deep foundation pit pipe piles. By setting up clamping rollers 8 and traveling rollers 5 with adjustable included angles and synchronous rotation, the testing instrument can fix the pipe pile and achieve the effect of actively adjusting the inclination angle. When the testing instrument moves upward along the pipe pile, the winding wheel 31 continuously releases a suspension rope 32 of the same length, so that the pipe pile can be compared with the suspension rope 32 that keeps it in a vertical state, thereby completing the verticality testing effect. The entire testing instrument does not require an additional power supply, can be operated by a single person, and is easy to use.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
