The construction quality of the V-shaped canyon high pier is directly related to the overall stability and safety of the bridge, and the verticality of the pier formwork assembly is one of the key factors affecting the construction quality. If the verticality of the formwork assembly deviates, it will cause uneven stress of the poured pier structure, easily causing cracks, deformation and other problems, and even seriously affecting the service life and traffic safety of the bridge. Therefore, it is crucial to accurately and efficiently monitor the verticality of the formwork assembly during the construction of the V-shaped canyon high pier.

[0049] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0050] like Figures 1-2 The V-shaped canyon pier verticality monitoring device shown has a pier formwork component I34 precisely embedded in the foundation to complete the foundation positioning. A base 1 is positioned on top of the formwork component I34 and is made of a high-strength alloy material to stably support the weight of the components above. A prism measuring rod 2, used in conjunction with a total station, is mounted on top of the base 1. The prism measuring rod 2 has a prism at its tip, and its surface is specially treated to more accurately reflect the signals emitted by the total station. Figure 3 As shown, a mounting base I15 is fixed to the top of the base 1. A universal ball bearing 16 is embedded inside the mounting base I15. Lubricant is applied between the balls of the universal ball bearing 16 and the mounting base I15 to reduce friction during rotation. The bottom end of the prism measuring rod 2 is fixedly connected to the universal ball bearing 16, allowing the prism measuring rod 2 to be adjusted at multiple angles using the universal ball bearing 16. During adjustment, a smooth rotation can be felt, facilitating the horizontal adjustment of the prism measuring rod 2 and finding a suitable position when used with a total station.

[0051] The outer wall of the mounting base I 15 has multiple clearance grooves 17, which are evenly distributed. The universal ball bearings 16 are placed inside these grooves, allowing the mounting base I 15 to contract evenly when compressed. A clamping sleeve 18 is fitted onto the bottom end of the prism measuring rod 2. The inner wall of the clamping sleeve 18 has fine threads that perfectly mesh with the threads on the outer wall of the mounting base I 15. When the prism measuring rod 2 is adjusted to the desired angle, the clamping sleeve 18 is held and rotated, gradually compressing the clearance grooves 17. This causes the inner wall of the mounting base I 15 to slowly tighten, tightly encasing the universal ball bearings 16, thus fixing the adjusted universal ball bearings 16 in place and ensuring that the prism measuring rod 2 will not easily wobble due to slight external vibrations during operation.

[0052] like Figure 8 As shown, guide rail I6 is placed on the ground and fitted onto the outside of template assembly I34. A gap is left between the inner side of guide rail I6 and the top connecting flange of template assembly I34 to avoid direct friction and wear.

The prism measuring rod 2 is provided with an adjusting support which is detachably connected with the plurality of connecting supports 5.

[0053] The outer ring of the connecting bearing 14 uniformly fixes four extension rods 3, the extension rods 3 are distributed in a radial manner, the other end is fixedly installed with a guide sleeve 4 through which a stud 19 penetrates, the inner wall of the guide sleeve 4 is smooth, so as to facilitate smooth movement of the stud 19 therein. The surface of the stud 19 is subjected to rust-proof treatment. The top of the connecting support 5 is fixed with a connecting pad 12 made of wear-resistant material, the top is provided with an internally threaded hole 23, the stud 19 is threadedly connected with the internally threaded hole 23, the outer wall of the stud 19 is threadedly sleeved with a nut ring 20, the edge of the nut ring 20 is provided with an anti-skid pattern, so as to facilitate hand tightening. The nut ring 20 abuts against the top end of the guide sleeve 4, through the stud 19, the bottom end of the stud 19 is in the internally threaded hole 23 at the top of the connecting support 5, after the nut ring 20 is tightened, the relative position of the stud 19 and the guide sleeve 4 is fixed, so as to realize stable connection of the adjusting support and the connecting support 5, at this time, during adjustment of the prism measuring rod 2 and the horizontal process, the guide rail I 6 and the guide rail II 7 are adjusted at the same time, so as to ensure that the centers of the guide rail I 6 and the guide rail II 7 coincide with the construction point, when disassembly is needed, after the nut ring 20 is loosened, the stud 19 can be taken out of the internally threaded hole 23, so as to facilitate disassembly.

[0054] The electromagnetic block 13 is provided on the plurality of connecting supports 5, and the adsorption surface of the electromagnetic block 13 is smooth and flat, so that the electromagnetic block 13 can be tightly attached to the template assembly I 34. The bottom of the connecting support 5 is provided with a sliding push rod 24 which is slidably penetrated, and the surface of the sliding push rod 24 is polished, so that the sliding push rod 24 can slide smoothly without jamming. The electromagnetic block 13 is fixed to the inner end of the sliding push rod 24, and the other end of the sliding push rod 24 is fixed with a limiting baffle 25, the diameter of the limiting baffle 25 is larger than the hole diameter of the penetration of the sliding push rod 24, so that the sliding push rod 24 cannot slide out of the mounting seat I 15. When the connecting support 5 needs to be fixed to the template assembly I 34, the electromagnetic block 13 is powered, the current passes through the coil inside the electromagnetic block 13 to generate a magnetic field, so that the electromagnetic block 13 generates a magnetic force to tightly adsorb on the template assembly I 34, so that the connecting support 5 and the template assembly I 34 are fixed, and the guide rail I 6 and the guide rail II 7 cannot move forward and backward and left and right after the connecting support 5 and the template assembly I 34 are fixed. After power-off, the magnetic field disappears, and the magnetic force also disappears, so that the connecting support 5 can be taken off from the template assembly I 34 with a little force.

[0055] The sliding support 8 is slidably arranged on the guide rail I 6 and the guide rail II 7, and the part of the sliding support 8 in contact with the guide rail is provided with a wear-resistant sliding block to reduce wear during sliding.

Figure 5 As shown in the figure, the output end of the motor 22 is fixedly sleeved with a rolling wheel 26, and the surface of the rolling wheel 26 is provided with anti-skid lines, so that the rolling wheel 26 is not easy to slip when it is in contact with the guide rail I 6. When the motor 22 is started, the rotor in the motor 22 starts to rotate, and drives the rolling wheel 26 to rotate through the output shaft, so that the rolling wheel 26 rolls on the guide rail I 6, and the friction generated during rolling drives the sliding support 8 to move on the guide rail I 6 and the guide rail II 7. In the moving process, the infrared distance meter 9 continuously emits infrared rays to the template assembly I 34, and calculates the distance between the guide rail I 6 and the template assembly I 34 by receiving the reflected infrared rays, and the measurement data is displayed on the display screen in real time. By analyzing these distance data, it can be judged whether the template assembly system composed of the template assembly I 34, the template assembly II 35, the template assembly III 36 and the template assembly IV 37 is offset or tilted. Figure 9 As shown in the figure, the output end of the motor 22 is fixedly sleeved with a rolling wheel 26, and the surface of the rolling wheel 26 is provided with anti-skid lines, so that the rolling wheel 26 is not easy to slip when it is in contact with the guide rail I 6. When the motor 22 is started, the rotor in the motor 22 starts to rotate, and drives the rolling wheel 26 to rotate through the output shaft, so that the rolling wheel 26 rolls on the guide rail I 6, and the friction generated during rolling drives the sliding support 8 to move on the guide rail I 6 and the guide rail II 7. In the moving process, the infrared distance meter 9 continuously emits infrared rays to the template assembly I 34, and calculates the distance between the guide rail I 6 and the template assembly I 34 by receiving the reflected infrared rays, and the measurement data is displayed on the display screen in real time. By analyzing these distance data, it can be judged whether the template assembly system composed of the template assembly I 34, the template assembly II 35, the template assembly III 36 and the template assembly IV 37 is offset or tilted.

[0056] As shown in the figure, the output end of the motor 22 is fixedly sleeved with a rolling wheel 26, and the surface of the rolling wheel 26 is provided with anti-skid lines, so that the rolling wheel 26 is not easy to slip when it is in contact with the guide rail I 6. When the motor 22 is started, the rotor in the motor 22 starts to rotate, and drives the rolling wheel 26 to rotate through the output shaft, so that the rolling wheel 26 rolls on the guide rail I 6, and the friction generated during rolling drives the sliding support 8 to move on the guide rail I 6 and the guide rail II 7.

After the avoiding groove 17 is extruded, the inner wall of the mounting seat I 15 will be tightened inward, tightly wrapping the universal ball 16, thereby firmly fixing the position of the adjusted prism measuring rod 2, avoiding the position deviation caused by external vibration in the subsequent monitoring process, and ensuring that the total station can stably and accurately receive the signal reflected by the prism.

[0061] The sliding push rod 24 is pushed to drive the electromagnet block 13 to approach the template assembly I 34, the power supply of the electromagnet block 13 is turned on, the current passes through the coil inside the electromagnet block 13 to generate a strong magnetic field, so that the electromagnet block 13 is firmly adsorbed on the metal surface of the template assembly I 34, thereby stably fixing the connecting support 5 and the guide rail I 6 and the guide rail II 7 connected therewith on the template assembly I 34.

[0062] Then the adjusting support and the connecting support 5 are separated, the nut ring 20 is unscrewed and the stud 19 is unscrewed from the internal threaded hole 23.

[0063] The motor 22 is powered on and runs, the output shaft drives the rolling wheel 26 to rotate, and the friction force generated between the rolling wheel 26 and the guide rail I 6 drives the sliding support 8 to move stably along the guide rail I 6 and the guide rail II 7. The infrared range finder 9 installed on the sliding support 8 is fixed through the rotating support 31, and in the moving process of the sliding support 8, the emitting end of the infrared range finder 9 continuously emits infrared light beams to the surface of the template assembly, and the infrared light beams are reflected back to the receiving end of the infrared range finder 9 after encountering the surface of the template assembly. The processor inside the infrared range finder 9 calculates the distance between the infrared range finder 9 and the surface of the template assembly according to the propagation time and the speed of the infrared light beams, and displays it on the display screen in real time. Because the sliding support 8 moves along the guide rail, the infrared range finder 9 measures the distances of different positions on the surface of the template assembly. The operator compares the measured distances of different positions to judge the position degree of the template assembly: if the measured distances of each point in the vertical direction are basically consistent, or the deviation is within the preset allowable error range, it indicates that the perpendicularity of the template assembly system is good; if there is a significant difference in the measured distances of different positions, and the deviation exceeds the allowable error range, it indicates that the template assembly system exists deviation and inclination phenomenon.

[0064] Then the template assembly II 35 is installed on the template assembly I 34, and the operator rotates the hand crank to drive the worm 29 to rotate, which drives the worm wheel 28 and the rotating shaft 27 connected thereto to rotate through the meshing transmission of the worm 29 and the worm wheel 28, and the rotating shaft 27 further drives the rotating support 31 to rotate, thereby adjusting the detection angle of the infrared distance meter 9 so that it can detect the distance of the surface of the template assembly II 35. The above method is used to sequentially detect the template assembly III 36 and the template assembly IV 37.

[0065] The sliding support 8 moves while the cleaning assembly moves synchronously with the infrared distance meter 9. One end of the telescopic rod 10 is fixedly connected to the other end of the rotating shaft 27 extending out of the mounting seat II 21 through a shaft coupling. When the rotating shaft 27 rotates to adjust the angle of the infrared distance meter 9, the telescopic rod 10 also rotates. When the sliding support 8 moves, the telescopic rod 10 moves together with the rotating shaft 27 and the sliding support 8. The telescopic rod 10 is composed of a plurality of telescopic joints with diameters decreasing in sequence. The outermost telescopic joint is connected to the rotating shaft 27, and the innermost telescopic joint is fixedly provided with a connecting end head 11 at the end. The shape of the connecting end head 11 is adapted to the detection position of the surface of the template assembly to be monitored, and the outer surface of the connecting end head 11 is wrapped with a cleaning towel. The cleaning towel is made of soft microfiber material and has good dust absorption and stain removal capabilities. Before the infrared distance meter 9 detects the surface of the template assembly to be monitored, the cleaning towel will first contact the detection position of the surface of the template assembly to be monitored. With the movement of the infrared distance meter 9, the cleaning towel gently wipes the surface of the template assembly to remove dust, stains and other impurities at the detection position, so as to avoid the influence of these impurities on the reflection of the infrared light beam, thereby ensuring the measurement accuracy of the infrared distance meter 9. When it is necessary to adjust the cleaning towel to be unable to contact the surface of the template assembly to be monitored, the screw 33 on the telescopic rod 10 is loosened, the bottom end of the screw 33 is separated from the inner telescopic joint, and at this time, the inner telescopic joint can be pulled to adjust the overall length of the telescopic rod 10, so that the cleaning towel maintains appropriate contact pressure with the surface of the template assembly to be monitored. After the adjustment is completed, the screw 33 is tightened, the bottom end of the screw 33 tightly abuts against the inner telescopic joint, the position of the inner telescopic joint is fixed, and the cleaning process is stable and reliable.

[0066] After all the detection is completed, the guide rail I 6 and the guide rail II 7 can be disassembled into two halves and removed from both sides of the template assembly I 34.

[0067] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
