DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0026] In one embodiment, see Figure 1-Figure 11 , a deep foundation pile verticality detector, comprising a support beam 1, a clamping mechanism 2 and a lifting and adjusting mechanism 3; 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 direction, a first support frame 4 is arranged on the left side of the support beam 1, the first support frame 4 is rotatably connected to a walking roller 5 arranged in a front-to-back direction, and the right side of the clamping side plate 7 is rotatably connected to the front and rear ends of the support beam 1, the front and rear two clamping side plates 7 are symmetrically arranged relative to the center of the support beam 1, and a second support frame 6 is arranged on the side of the clamping side plate 7 close to the walking roller 5, the second support frame 6 is rotatably connected to a clamping roller 8 in the same plane as the walking roller 5, the side walls of the walking roller 5 and the clamping roller 8 are both concave arc surfaces, so that the clamping roller 8 and the walking roller 5 can better contact with the side wall of the pipe pile, and a rubber layer can be arranged on the side walls of the clamping roller 8 and the walking roller 5 to improve the friction; The lifting and lowering adjustment mechanism 3 includes a through hole 26 arranged in the middle of the support beam 1. The through hole 26 is arranged in a front-to-back direction so that the left and right sides of the support beam 1 are connected through the through hole 26. A cross beam 27 arranged in a front-to-back direction is arranged in the middle of the through hole 26. The front and rear sides of the cross beam 27 are fixedly connected with fixed rods 29 arranged in a left-to-right direction. The left end of the fixed rod 29 is fixedly connected with a second fixed block 41. The middle part of the second fixed block 41 is rotatably connected with a lifting drive wheel 28. The lifting drive wheel 28 is tightly attached to the walking roller 5. Therefore, when the lifting drive wheel 28 rotates, it can drive the walking roller 5 to rotate. A support plate 30 is arranged below the right side of the support beam 1. A winding wheel 31 arranged in a front-to-back direction is arranged above the support plate 30. A suspension rope 32 is wound around the outside of the wheel 31, and a weight 33 is provided at the free end below the suspension rope 32. The weight 33 is acted upon by gravity, so that the suspension rope 32 remains in a vertical downward state, thereby achieving the effect of verticality detection by comparing the pipe pile with the suspension rope 32. A rotation drive assembly 34 is provided at the right end of the fixed rod 29. The rotation drive assembly 34 can drive the winding wheel 31 and the lifting drive wheel 28 to rotate synchronously, and make the linear speed of the winding wheel 31 and the outer side of the walking roller 5 the same. Therefore, when the walking roller 5 moves upward along the side wall of the pipe pile, the winding wheel 31 will adaptively release the suspension rope 32, and the released suspension rope 32 is the same as the rising distance, so that the weight 33 is always at the bottom.

[0027] In one case of the present embodiment, a synchronous rotation component 9 is arranged between the walking roller 5 and the clamping roller 8. The synchronous rotation component 9 realizes the effect of power transmission, so that the walking roller 5 can drive the front and rear clamping rollers 8 to rotate synchronously, and a clamping drive component 10 is arranged above the support beam 1. The clamping drive component 10 can drive the front and rear clamping side plates 7 to rotate synchronously in opposite directions, so that the front and rear 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 and the pipe pile.

[0028] In one case of the present embodiment, the clamping drive assembly 10 includes a slide groove 12 arranged on the upper surface of the support beam 1, the slide groove 12 is arranged in a front-to-back direction, and the front and rear ends of the slide groove 12 are slidably connected with a first slider 14, the right side surface 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 vertical rod 16, the lower end of the vertical rod 16 is fixedly connected to the right end of the upper surface of the clamping side plate 7, and the front and rear ends of the slide groove 12 are provided with a first fixed plate 11 fixedly connected to the support beam 1, the middle part of the first fixed plate 11 is rotatably connected to the front and rear ends of the screw rod 13, the front and rear sides of the screw rod 13 are provided with threads of opposite rotation directions, and the front and rear sides of the screw rod 13 are respectively threadedly connected to the front and rear first sliders 14, so when the screw rod 13 rotates, the front and rear first sliders 14 separate from each other or move closer to each other, so that the front and rear clamping side plates 7 rotate closer to or away from each other, thereby achieving the effect of clamping drive.

[0029] In one case of the present embodiment, the synchronous rotation component 9 includes a sliding sleeve 23 arranged between the walking roller 5 and the clamping roller 8, and the front and rear sides of the sliding sleeve 23 are slidably connected with an extension rod 24, a spring located inside the sliding sleeve 23 is arranged between the two extension rods 24, and a universal connector 25 is arranged at the end of the extension rod 24 away from the sliding sleeve 23, and the front and rear two universal connectors 25 are respectively connected to the front and rear clamping rollers 8 and the end of the walking roller 5. Therefore, when the walking roller 5 rotates, the walking roller 5 drives the sliding sleeve 23 and the extension rod 24 to rotate through the universal connector 25, and the extension rod 24 drives the clamping roller 8 to rotate through the universal connector 25. In the clamping process, the angle between the clamping roller 8 and the walking roller 5 changes. At this time, the extension rod 24 moves inside the sliding sleeve 23, so that the universal connector 25 always maintains the effect of power transmission. In order to ensure the stability of the sliding sleeve 23, a second fixed plate 17 is set at the front and rear ends of the left side of the extended beam 53, the second fixed plate 17 is fixedly connected to a sliding rod 18 arranged in a front-to-rear direction, the middle part of the sliding rod 18 is slidably connected to the second sliding block 20, the left side of the second sliding block 20 is rotationally connected to the right end of the second top plate 21, the left end of the second top plate 21 is rotationally connected to the right side of the fixed seat 22, the middle part of the fixed seat 22 is fixedly connected to the middle part of the sliding sleeve 23, so that the sliding sleeve 23 maintains a horizontal state for operation, and a buffer spring 19 is set between the second fixed plate 17 and the second sliding block 20, so that the sliding sleeve 23 will not shake.

[0030] In one case of the present embodiment, the rotary drive assembly 34 includes an extending beam 53 arranged on the front and rear sides of the lower side of the through hole 26, and the right end of the extending beam 53 is rotatably connected to a rotary drive wheel 40 arranged in a front-to-rear direction. The rotary drive wheel 40 is pressed on the top of the winding wheel 31, so when the rotary drive wheel 40 rotates, the winding wheel 31 will adaptively rotate, thereby achieving the effect of releasing the suspension rope 32, and the first fixed block 35 is fixedly connected to the right end of the fixed rod 29, and the middle parts of the front and rear first fixed blocks 35 are rotatably connected to the front and rear sides of the rotating wheel 36, and the middle part of the rotating wheel 36 is recessed, and the annular rotating belt 37 is sleeved on the outside of the rotating wheel 36, and a gear lever 49 is provided on the left and right sides of the rotating wheel 36, and the gear lever 49 prevents the rotating belt 37 from rotating. The first pulley 38 is provided at the front and rear ends of the rotating wheel 36, and the first pulley 38 drives the second pulley 39 and the third pulley 42 to rotate at the same time through the synchronous belt 43. The second pulley 39 is fixed to the front and rear ends of the rotating drive wheel 40, and the third pulley 42 is fixed to 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, so that when the walking roller 5 drives the detector to move up and down, the winding wheel 31 will synchronously retract or release the suspension rope 32.

[0031] The third fixing block 50 is rotatably connected to the front and rear sides of the winding wheel 31, and a limit plate is provided at the lower end of the top rod 52, and a tensioning spring 51 is provided between the limit plate and the supporting plate 30. The tensioning spring 51 is sleeved on the outside of the top rod 52, and the tensioning spring 51 will push the top rod 52 upward, so that the winding wheel 31 will be tightened against the outside of the rotating driving 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 adaptively move upward, so that the rotating driving wheel 40 will always drive the winding wheel 31 to rotate, and even if the diameter of the suspension rope 32 wrapped outside is reduced, the linear speed outside the winding wheel 31 will remain stable, so that the release speed of the suspension rope 32 remains stable.

[0032] In one case of the present embodiment, limit teeth 44 which rotate synchronously with the rotating wheel 36 are provided on the front and rear sides of the rotating wheel 36, and a hanging frame 47 is provided on the upper surface of the first fixed block 35, and the hanging frame 47 is slidably connected with a vertically arranged limit slide bar 48, and the lower end of the limit slide bar 48 is fixedly connected with a limit head 45 which cooperates with the limit tooth 44, and a limit spring 46 is provided between the hanging frame 47 and the limit head 45, and the limit spring 46 is sleeved on the outside of the limit slide bar 48, and the limit spring 46 will push the limit head 45 downward to press against the outside of the limit tooth 44, so that when the rotating wheel 36 rotates with the rotating belt 37, the limit head 45 will rise and fall, but when the rotating belt 37 is loosened from the rotating wheel 36, the limit head 45 will press against the limit tooth 44, so that the rotating wheel 36 will not rotate actively, so when the detector moves to a higher position, the detector will not fall due to the gravity of the detector.

[0033] During the implementation of this embodiment, the pipe pile is lifted vertically by the lifting equipment, and the lower end of the pipe pile is dropped to the position where it needs to be installed. At this time, the verticality detector is installed.

[0034] Take out the detector, place the support beam 1 on the right side of the pipe pile with it facing forward and backward, and rotate the screw rod 13. The screw rod 13 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 respectively clamped on the side walls of the pipe pile, and as the clamping roller 8 is tightened, the two clamping rollers 8 and the traveling roller 5 achieve the effect of automatic leveling. 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, and at this time the clamping roller 8 is located on the left side of the pipe pile, so that the detector will not loosen from the right side of the pipe pile.

[0035] The operator pulls the rotating belt 37 downward, and the rotating belt 37 is wrapped around the outside of the rotating wheel 36. The rotating belt 37 drives the rotating wheel 36 to rotate, so that the lifting drive wheel 28 and the rotating drive wheel 40 rotate synchronously. The lifting drive wheel 28 drives the detector to move upward along the side wall of the pile through the walking roller 5, and the rotating drive wheel 40 drives the winding wheel 31 to release the suspension rope 32. When the detector moves to the top of the pile, the suspension rope 32 is in a vertical state under the action of the gravity of the weight 33. By comparing the angle between the suspension rope 32 and the pile itself, the pile is adjusted to keep the pile in a vertical state.

[0036] The upper end of the pipe pile is pressurized by the pressure-applying device, so that the pipe pile is slowly inserted into the ground, and the angle between the suspension rope 32 and the pipe pile is continuously compared in the initial stage of insertion to ensure that the pipe pile always remains in a vertical state. When the weight 33 contacts the ground, the pipe pile is also inserted into the ground for a distance without deflection. At this time, the rotating belt 37 can be used to drive the rotating wheel 36 to rotate in the reverse direction, so that the walking roller 5 drives 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 rod 13 can be rotated in the reverse 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 pressure on the pipe pile can be continued to be applied again, so that the pipe pile can be completely inserted into the ground.

[0037] The present invention is applicable to a verticality detector for deep foundation piles. By arranging a clamping roller 8 and a walking roller 5 with adjustable angles and synchronous rotation, the detector can fix the pile and actively adjust the inclination angle. When the detector moves upward along the pile, the winding wheel 31 continuously releases a suspension rope 32 of the same length, so that the pile can be compared with the suspension rope 32 maintained in a vertical state, thereby achieving the effect of verticality detection. The entire detector does not require additional power supply, can be operated by a single person, and is easy to use.

[0038] 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 present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
