Description

Technical Field

[0001] The present invention relates to the technical field of verticality detection, in particular to a verticality detection tool for bridge pier construction. Background Art

[0002] Bridge piers are a crucial component of bridge structures, used to support the bridge superstructure and transfer loads to the foundation. During the construction process, due to their own weight and temporary construction loads, the abutments and foundations gradually sink, which may cause the bridge piers to tilt during installation. Therefore, verticality detection tools must be used during the construction of bridge piers to detect their verticality. This can strengthen the quality control of the bridge pier construction process and strengthen the management of the inspection and acceptance procedures.

[0003] For example, the patent name disclosed in the prior art with the announcement number "CN220729251U" is "A warning type verticality real-time measurement tool", which discloses that the composite gear includes an amplifying wheel and a transmission gear of a coaxial integrated structure, the amplifying wheel is located at the rear side of the transmission gear and the diameter of the amplifying wheel is larger than the diameter of the transmission gear, the diameter of the amplifying wheel is smaller than the diameter of the counterweight gear, the counterweight gear and the transmission gear are meshed with each other, a contact-type pointer is fixed at the middle position of the lower end of the front of the amplifying wheel, a scale line is provided on the front of the panel corresponding to the bottom edge of the amplifying wheel, and a left limit contact is provided on the left side of the scale line and a right limit contact is provided on the right side, an alarm wire is provided at the lower end of the front of the panel, and an alarm and a power supply are installed on the alarm wire, and the patent name disclosed in the prior art with the publication number "CN117451007A" is "A bridge pier formwork verticality detection device", which discloses that four pull ropes can be adjusted separately, so that Prove that the balance plate is in a horizontal state, then rotate the second limit bolt so that one end of the sliding block pushes the sliding block upward to compress the second spring until the driving gear and the driven gear are engaged, and then rotate the second knob to make one of the second rotating rods drive the two transmission parts to rotate. Relying on the steering part, the two power transmission parts are rotated in opposite directions, and the winding devices on both sides are rotated in opposite directions. In this way, the four pull ropes can be reeled in synchronously, thereby raising the laser rangefinder to the specified measurement position. The laser rangefinder can accurately measure the horizontal distance from it to the pier column template. By relying on the horizontal distance values L1 and L2 measured at two different heights and combining the height difference H between the two measuring points, the inclination angle of the pier column template can be calculated, thereby judging whether the verticality of the pier column template meets the construction requirements. In addition, the detection device can measure multiple sets of data to verify the detection results, effectively ensuring the accuracy of the measurement results.

[0004] When the verticality detection tooling in the above-mentioned prior art is in use, the laser rangefinder inside it directly measures the horizontal distance from it to the bridge pier. If after the bridge pier is demolded, the surface of the bridge pier is uneven due to improper demolding operation or other factors, when the part of the bridge pier measured by the laser rangefinder is uneven, it will cause errors in the measured inclination, which will in turn affect the accuracy of the verticality detection, and thus affect the verticality detection operation. Therefore, we have proposed a verticality detection tooling for bridge pier construction to solve the above-mentioned problems. Summary of the Invention

The specific contents are as follows:

[0017] (1) The auxiliary roller is placed in contact with the outer side of the bridge pier, so that the auxiliary roller can block the inner concave part of the bridge pier. Therefore, the horizontal distance value between the laser rangefinder and the bridge pier can be obtained by adding the value of the horizontal distance between the laser rangefinder and the auxiliary roller to the diameter of the auxiliary roller. This reduces the error of the inclination measurement data and improves the accuracy of the verticality detection, so that it can be accurately judged whether the verticality of the bridge pier meets the construction requirements;

[0018] (2) While the auxiliary roller drives the upper processing plate to move upward, the upper processing plate is lifted and lowered reciprocatingly by the automatic control component, so that the upper processing plate can scrape off the protruding impurities on the surface of the bridge pier while moving upward, thereby further avoiding the influence of the protruding impurities on the accuracy of the verticality detection in the later stage, and reducing the error of the inclination measurement data in the later stage;

[0019] The upper processing plate is connected to the guide plate through a rotating rod and a first vortex spring, which ensures that the upper processing plate is always in close contact with the outer side of the inclined bridge pier. At the same time, the scraped raised impurities can be diverted and discharged through the arc-shaped guide plate to prevent the scraped raised impurities from falling onto the auxiliary roller.

[0020] Impurities adhering to the outer side of the auxiliary roller can be scraped off by the arc-shaped lower processing plate to prevent the impurities from affecting the accuracy of the measurement data.

[0021] (3) By using the control rope in the automatic control component in conjunction with the single-rotation reciprocating screw, the upper processing plate can be automatically driven to move up and down in a reciprocating manner without the need for an additional power source, making the entire verticality detection tooling structure simple and the production cost low.

[0034] 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.

The laser emitted by the laser rangefinder 8 is perpendicular to and intersects with the horizontal center line of the auxiliary roller 11. The support assembly includes a connecting frame 9 symmetrically installed on the upper rear side of the load-bearing plate 7, and the rear end of the connecting frame 9 is connected to the cross frame 10, and the inner side wall of the cross frame 10 is grooved and slidably connected with a movable frame 13. The movable frame 13 is rotatably installed on both ends of the auxiliary roller 11, and a guide column 131 is provided inside the end of the movable frame 13 away from the auxiliary roller 11. The guide column 131 is installed in a groove opened inside the cross frame 10, and a reset spring 132 is nested and connected to the outer side of the guide column 131.

[0037] An upper regulating frame 14 is connected to the interior of one end of the horizontal frame 10 close to the auxiliary roller 11, and an inclined upper processing plate 12 and an arc-shaped guide plate 15 are provided above the auxiliary roller 11. The left and right sides of the guide plate 15 are connected to the other end of the upper regulating frame 14. A rotating rod 151 is installed in a groove inside the rear side of the guide plate 15, and the upper processing plate 12 is fixed to the outer side of the rotating rod 151. The left and right ends of the rotating rod 151 are nested and connected to the outer sides of the first vortex spring 152. The automatic regulating component includes a single-rotation reciprocating screw 18 installed in a groove opened inside the rear end of the horizontal frame 10, and the outer side of the single-rotation reciprocating screw 18 is threadedly connected to a connecting block 19 , and the rear side of the connecting block 19 is connected to the upper regulating frame 14 through a second manual telescopic rod 142. The lower part of the upper regulating frame 14 is connected to the upper surface of the movable frame 13 through a first manual telescopic rod 141. The auxiliary roller 11 and the guide plate 15 move back and forth synchronously. The outer side of the lower end of the single-rotation reciprocating screw 18 is nested and connected with a second vortex spring 181. The upper end of the second vortex spring 181 is connected to the bottom surface of the cross frame 10. The outer side of the single-rotation reciprocating screw 18 corresponding to the second vortex spring 181 is wound with a regulating rope 17. The lower end of the regulating rope 17 is connected to the upper surface of the support plate 2 after being guided by the guide wheel installed on the bottom surface of the cross frame 10.

[0038] First, install the clamp 4 on the rear side of the entire verticality detection tooling on the outside of the cylindrical bridge pier. At this time, the outer sides of the auxiliary roller 11 and the upper processing plate 12 are in contact with the front side of the bridge pier, and the reset spring 132 is in a squeezed state. Then, use the spirit level 5 to determine whether the support plate 2 is in a horizontal position. When the support plate 2 is not in a horizontal position, manually rotate the worm 32, and the worm 32 drives the worm wheel 31 and the regulating rod 3 to rotate. The regulating rod 3 drives the support plate 2 to rotate. When the spirit level 5 shows that the support plate 2 is in a horizontal position, stop rotating the worm 32, so that the support plate 2 can be adjusted to a horizontal position. The worm 32 and the worm wheel 31 can be self-locking, thereby ensuring that the support plate 2 is placed stably (the level 5 is a prior art and will not be described in detail here). At the same time, through the cooperation of the rotating rod 151 and the first vortex spring 152, the outer side surface of the upper processing plate 12 is always in contact with the front side surface of the bridge pier. If there is a concave in the detection area of the bridge pier, the auxiliary roller 11 can block the concave part, and then the first detection work can be carried out. The diameter of the auxiliary roller 11 is D1. The laser emitted by the laser rangefinder 8 just irradiates the horizontal center line of the auxiliary roller 11. The horizontal distance detected by the laser rangefinder 8 to the auxiliary roller 11 is L11. At this time, the horizontal distance between the laser rangefinder 8 and the bridge pier during the first detection is L11+D1=L1.

[0039] When the first detection is completed, the electric push rod 6 is started, and the electric push rod 6 drives the carrying plate 7 and the laser rangefinder 8 to rise to a certain height position. At this time, the carrying plate 7 drives the auxiliary roller 11 and the upper processing plate 12 to move upward to a certain height position through the connecting frame 9 and the cross frame 10. At the same time, when the cross frame 10 rises, it pulls the regulating rope 17, so that the regulating rope 17 drives the single-rotation reciprocating screw rod 18 to rotate. At this time, the second vortex spring 181 accumulates force, and when the single-rotation reciprocating screw rod 18 rotates, it drives the connecting block 19 connected to the outer thread to rise and fall. Then the connecting block 19 drives the second manual telescopic rod 142, the upper regulating frame 14 and the guide plate 15 to rise and fall, and the guide plate 15 drives the upper processing plate 12 to rise and fall, and then the upper processing plate 12 is lifted and lowered at the same time during the rising process. Therefore, the upper processing plate 12 can scrape off the protruding impurities on the outer side of the bridge pier to avoid affecting the accuracy of the later measurement data. At this time, the protruding impurities are discharged through the arc-shaped guide plate 15.

[0040] During the upward movement of the auxiliary roller 11 and the upper processing plate 12, when the bridge pier is tilted, the stored force of the return spring 132 will drive the moving frame 13 and the auxiliary roller 11 to move forward or backward, so that the auxiliary roller 11 is always in contact with the outer side of the tilted bridge pier, and the moving frame 13 will drive the upper regulating frame 14 to move forward or backward through the first manual telescopic rod 141. At this time, the setting of the second manual telescopic rod 142 will not affect the forward or backward movement of the upper regulating frame 14. The upper regulating frame 14 will drive the guide plate 15 and the upper processing plate 12 to move forward or backward together. At the same time, through the setting of the rotating rod 151 and the first vortex spring 152, the upper processing plate 12 is rotatably connected to the guide plate 15, so that the upper processing plate 12 can always be in contact with the outer side of the tilted bridge pier. Contact, when it rises to a certain height, the electric push rod 6 stops working, and then a second detection is carried out. The diameter of the auxiliary roller 11 is D1, and the laser rangefinder 8 detects that the horizontal distance from the auxiliary roller 11 is L22. At this time, the horizontal distance between the laser rangefinder 8 and the bridge pier during the second detection is L22+D1=L2. If L1 is equal to L2, the measured inclination is 0, which proves that the bridge pier is installed vertically. At this time, the verticality of the bridge pier meets the construction requirements. If L1 is greater than or less than L2, it proves that the bridge pier is installed at an angle. At this time, combined with the height difference H between the two measuring points, the inclination of the bridge pier can be calculated, thereby judging whether the verticality of the bridge pier template meets the construction requirements. Since the calculation of the inclination of the bridge pier is an existing technology, it will not be introduced in detail here.

[0041] Example 2: The verticality detection tooling for bridge pier construction in this embodiment can further improve the accuracy of measurement data and reduce measurement errors based on Example 1. For specific structure, please refer to the attached Figure 5 As shown, a lower processing plate 16 is fitted below the auxiliary roller 11. The lower processing plate 16 is arranged in an arc shape, and the left and right sides of the lower processing plate 16 are connected to the bottom surface of the movable frame 13 through a lower regulating frame 161. The upper regulating frame 14, the movable frame 13, the lower regulating frame 161 and the connecting frame 9 are all arranged in an "L" shape.

[0042] When the auxiliary roller 11 rotates and moves upward, the arc-shaped lower processing plate 16 can scrape off the impurities adhered to the outer side of the auxiliary roller 11, preventing the impurities from adhering to the outer side of the auxiliary roller 11 and affecting the accuracy of the subsequent measurement data, thereby completing a series of tasks.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
