[0021] The present invention provides components such as a fixed-distance tooth plate, a pinion, a penetration frame and a bent shaft. When the penetration frame is driven by a pull rope to move downward, the slider applies a thrust to the slider at the upper end of the penetration frame under the resistance of the upper frame and the lower frame, and the pinion moves to the upper end of the fixed-distance tooth plate at the same time. The pinion meshes with the fixed-distance tooth plate and drives the drawing pen through the bent shaft to be perpendicular to the drawing paper surface it contacts, so that the drawing pen can draw lines on the drawing paper surface when moving downward. When the penetration frame moves upward, the slider first moves upward relative to the slider under the resistance of the upper frame and the lower frame, and then pushes the slider to move upward after the lower end of the penetration frame contacts the slider. After the pinion meshes with the fixed-distance tooth plate, it drives the bent shaft and the drawing pen to rotate. The drawing pen rotates to a vertical state, so that the drawing pen will not contact the drawing paper when moving upward, thereby preventing the drawing pen from drawing on the drawing paper surface when moving upward and confusing the downward lines.

[0024] The following is combined with Figure 1-Figure 9 The present invention is described in further detail.

[0025] The embodiment of the present invention discloses a device for measuring the verticality of a pipe pile in a construction project. Figure 1-Figure 9 As shown, it includes a central column 1, a plurality of telescopic structures 5 are installed at the lower end of the central column 1, a frame structure 6 is installed at one end of the telescopic structure 5 away from the central column 1, a shaft sleeve 12 is slidably sleeved on the outer surface of the central column 1, a power telescopic rod 13 is fixed on the upper surface of the shaft sleeve 12, the power telescopic rod 13 is fixed to the central column 1, and the power telescopic rod 13 is telescopically moved to drive the shaft sleeve 12 to move up and down relative to the central column 1, the lower end of the central column 1 is in contact with the upper end of the pipe pile, and the detection position can be changed by manually controlling the rotation of the central column 1 relative to the pipe pile.

[0026] The telescopic structure 5 includes an inner transverse frame 51 and an inner rod 52. The inner rod 52 is slidably inserted into the inner transverse frame 51. The inner transverse frame 51 is fixed to the central column 1. The upper surface of the inner rod 52 is rotatably connected with a hinged rod 53. The upper end of the hinged rod 53 is rotatably connected to the sleeve 12. The inner rod 52 is connected to the upper end of the connected frame structure 6. When the sleeve 12 moves up and down, the hinged rod 53 pushes the inner rod 52 to slide in the inner transverse frame 51 to control the distance between the inner rod 52 and the central column 1.

[0027] A slider 2 is inserted into the frame structure 6 for damping sliding. A contact rod 3 is elastically slidably penetrated on one side of the slider 2 close to the axis of the central column 1. A drawing structure 7 is installed on the end of the contact rod 3 away from the axis of the central column 1. The drawing structure 7 is connected to the adjacent slider 2. Two shaft cylinder structures 8 are arranged on one side of the drawing structure 7. Both ends of each shaft cylinder structure 8 are rotatably connected to both ends of the adjacent frame structure 6 respectively. A damping structure 9 is installed on the upper end of each shaft cylinder structure 8, and the damping structure 9 is connected to the adjacent frame structure 6.

[0028] A vertical tooth plate 4 is installed at one end of the slider 2 away from the center column 1, and a one-way transmission structure 10 is meshed with the side of the vertical tooth plate 4 close to the center column 1. The one-way transmission structure 10 is rotatably connected to the upper end of the adjacent frame structure 6, and the one-way transmission structure 10 is connected to the upper end of the adjacent shaft cylinder structure 8. When the vertical tooth plate 4 moves upward and meshes with the one-way transmission structure 10, the connected shaft cylinder structure 8 can be driven to rotate through transmission. When the vertical tooth plate 4 moves downward, it will not drive the multi-connected shaft cylinder structure 8 to rotate.

[0029] The frame structure 6 includes an upper frame 61 and a lower frame 62 . The upper frame 61 and the lower frame 62 are slidably connected to each other, and the upper frame 61 is connected to the adjacent telescopic structure 5 .

[0030] The shaft cylinder structure 8 includes an upper shaft wheel 81 and a lower shaft wheel 82, and the upper shaft wheel 81 and the lower shaft wheel 82 are coaxially slidably connected. The ends of the upper shaft wheel 81 and the lower shaft wheel 82 that are away from each other are respectively rotatably connected to the upper frame 61 and the lower frame 62. When the distance between the upper frame 61 and the lower frame 62 changes, the distance between the connected upper shaft wheel 81 and the lower shaft wheel 82 changes synchronously.

[0031] A threaded rod 63 is rotatably passed through the upper end of the upper frame 61, and the upper end of the lower frame 62 is threadedly sleeved on the lower end of the threaded rod 63. The slider 2 is inserted into the upper frame 61 and the lower frame 62 in a damped sliding manner. The distance between the upper frame 61 and the lower frame 62 can be adjusted by rotating the threaded rod 63.

[0032] A drawing paper 11 is arranged on one side of the drawing line structure 7, and two ends of the drawing paper 11 are respectively wound and connected to the outer surfaces of two adjacent shaft cylinder structures 8. The damping structure 9 includes a damping disc 91 and an elastic damping plate 92. The elastic damping plate 92 is fixed to the adjacent upper shaft wheel 81. The inner annular surface of the damping disc 91 is a groove-shaped structure. The elastic damping plate 92 is engaged with the groove-shaped structure of the damping disc 91. The elastic damping plate 92 is inserted into the damping disc 91 to generate resistance to the rotation of the upper shaft wheel 81. When the upper shaft wheel 81 and the lower shaft wheel 82 on one side rotate to wrap around the drawing paper 11, the drawing paper 11 can remain taut. The damping disc 91 is fixed to the upper end of the upper frame 61, and the two ends of the drawing paper 11 are respectively detachably wound and connected with the upper shaft wheel 81 and the lower shaft wheel 82 on both sides, and the drawing paper 11 can be removed from the upper shaft wheel 81 and the lower shaft wheel 82.

[0033] The drawing structure 7 includes a bent shaft 71 and a pinion 72. The bent shaft 71 is coaxially connected to the contact rod 3 for rotation. The bent shaft 71 is L-shaped. One end of the bent shaft 71 coaxial with the contact rod 3 is a prism end. The pinion 72 is slidably sleeved on the outer surface of the bent shaft 71. The pinion 72 slides relative to the bent shaft 71 and rotates synchronously. A fixed-pitch tooth plate 73 is meshed on one side of the pinion 72. Both the upper and lower ends of the fixed-pitch tooth plate 73 are arc-shaped toothless ends. The meshing side of the fixed-pitch tooth plate 73 and the pinion 72 is concave. A through frame 74 is provided on one side of 73, and the two ends of the through frame 74 are respectively fixed to the two ends of the spacing tooth plate 73, and the through frame 74 is slidably connected with the adjacent slider 2. The friction between the through frame 74 and the slider 2 is less than the friction between the slider 2 and the upper frame 61 and the lower frame 62. When the through frame 74 moves, the through frame 74 first moves relative to the slider 2, and then drives the slider 2 to move synchronously after one end of the through frame 74 contacts the slider 2. When the through frame 74 moves relative to the slider 2, it drives the spacing tooth plate 73 to engage with the pinion 72.

[0034] The upper frame 61 and the lower frame 62 are both installed with synchronous motors 79 at one end away from each other, and pull ropes 710 are fixed at the upper and lower ends of the through-frame 74. The two pull ropes 710 are respectively wound and connected with the output ends of the two synchronous motors 79 at one end away from each other. The two synchronous motors 79 rotate synchronously. The upper synchronous motor 79 can wind the connected pull rope 710, and the lower synchronous motor 79 can pay out the connected pull rope 710. Conversely, the upper synchronous motor 79 pays out the pull rope 710, and the lower synchronous motor 79 winds the pull rope 710, which can respectively pull the through-frame 74 up and down.

[0035] A pen holder 75 is installed at the end of the bending shaft 71 away from the contact rod 3, and a plurality of elastic splints 76 are evenly fixed inside the pen holder 75. An end of the pen holder 75 away from the adjacent drawing paper 11 is elastically connected to an end holder 77, and a drawing pen 78 is installed inside the end holder 77 and between the plurality of elastic splints 76. The plurality of elastic splints 76 inside the end holder 77 can limit and clamp the drawing pen 78 therebetween. The elastic connection between the end holder 77 and the pen holder 75 has a tendency to push the drawing pen 78 closer to the drawing paper 11. The axis of the drawing pen 78 is perpendicular to the axis of the adjacent contact rod 3. When the through-frame 74 moves downward, the pinion 72 moves to the upper end of the fixed-distance tooth plate 73, and the pinion 72 is connected to the fixed-distance tooth plate 73 by the pinion 72. The spacing tooth plate 73 is meshed, and the bending shaft 71 drives the drawing pen 78 to be perpendicular to the surface of the drawing paper 11 it contacts, so that the drawing pen 78 can draw lines on the surface of the drawing paper 11 while moving downward. The drawing pen 78 synchronously draws corresponding lines on the drawing paper 11 due to changes in the circumferential surface of the pipe pile. The surface of the drawing paper 11 with different inclinations of the pipe pile presents different curved lines. When the through frame 74 moves upward, the pinion 72 meshes with the spacing tooth plate 73 and drives the bending shaft 71 and the drawing pen 78 to rotate. The drawing pen 78 rotates to a vertical state, so that the drawing pen 78 will not contact the drawing paper 11 when moving upward, preventing the drawing pen 78 from moving upward and drawing the line on the drawing paper 11 The surface is confused with the downward line.

[0036] The one-way transmission structure 10 includes a one-way gear 101, a worm 102 and a worm wheel 103. The worm wheel 103 is fixedly sleeved on the upper end of the adjacent upper shaft wheel 81. The worm wheel 103 is meshed with the worm 102. The worm 102 is rotatably connected to the upper end of the upper frame 61. The one-way gear 101 is coaxially rotatably sleeved on the outer surface of the worm 102. The worm 102 is located inside the one-way gear 101 and has a ratchet groove structure at one end. The inner ring surface of the one-way gear 101 is elastically rotatably connected with ratchet teeth 104. The ratchet teeth 104 are connected to the one-way gear 101. 04 meshes with the ratchet groove structure of the worm 102. When the vertical tooth plate 4 moves upward and meshes with the one-way gear 101, the one-way gear 101 pushes the worm 102 to rotate through the ratchet teeth 104, so that the worm 102 drives the connected upper shaft wheel 81 to rotate. When the vertical tooth plate 4 moves downward, the ratchet teeth 104 are meshed with the one-way gear 101 to drive the ratchet teeth 104 to rotate in the opposite direction. The ratchet teeth 104 will not push the worm 102 to rotate by rotating relative to the one-way gear 101, and no power will be output to the worm 102.

[0037] A method for using a construction pipe pile verticality measuring device comprises the following steps: S1: The pipe pile to be inspected is placed between a plurality of frame structures 6, with the central column 1 in contact with the upper end of the pipe pile.

[0038] S2: When the slider 2 moves downward, the drawing line structure 7 draws a line on the drawing paper 11. At the same time, the contact rod 3 slides relative to the circumferential surface of the pile under the elastic connection with the slider 2. The changes of the circumferential surface of the pile are synchronously drawn by the drawing line structure 7 on the drawing paper 11. By observing the curve on the surface of the drawing paper 11, the inclination of the pile at different positions can be observed.

[0039] S3: After the slider 2 moves upward again to drive the vertical tooth plate 4 upward to engage with the one-way transmission structure 10, the slider 2 continues to drive the vertical tooth plate 4 upward, driving the connected shaft cylinder structure 8 to rotate, driving the drawing paper 11 to move, so that the drawing paper 11 with the drawing line part is misaligned with the drawing line structure 7, so that the new blank part of the drawing paper 11 contacts the drawing line structure 7.

[0040] S4: After the central column 1 is controlled to move relative to the pipe pile, the contact rod 3 detects the change in position, and at the same time, the line drawing structure 7 can draw lines on the blank position of the drawing paper 11 after the movement.

[0041] The working principle is: make the pipe pile located between multiple frame structures 6, control the contact rod 3 to contact the circumferential side of the pipe pile, and at the same time make the contact rod 3 elastically propped up relative to the slider 2, so that the slider 2 moves downward, and the contact rod 3 can move synchronously according to the concave-convex changes on the surface of the pipe pile, driving the drawing line structure 7 to draw lines on the drawing paper 11, and the drawing line structure 7 draws corresponding curved lines on the surface of the drawing paper 11 according to the different positions and different inclinations of the surface of the pipe pile. When the slider 2 moves upward again to drive the vertical tooth plate 4 upward to engage with the one-way transmission structure 10, it drives the connected shaft cylinder structure 8 to rotate, changes the position of the drawing paper 11, and makes the drawing paper 11 of the drawing line part misaligned with the drawing line structure 7. Then, after changing the pipe pile part contacted by the contact rod 3, when it moves downward again, the drawing line structure 7 can draw lines on the new part of the drawing paper 11. At the same time, after all measurements are completed, the drawing paper 11 is disassembled, and the drawing paper 11 is unfolded to compare and observe multiple drawing lines.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
