Description

Technical Field

[0001] The present application relates to the technical field of bridge detection, and more specifically, to a device for detecting the verticality of a bridge pile. Background Art

[0002] The beam column is an important part of the bridge, and its quality is related to the quality and safety of the entire bridge. After the construction of the bridge column is completed, the verticality of the column is an indispensable inspection item. If the verticality of the bridge column exceeds the limit, it will seriously affect the stress state of the column and seriously endanger the safety of the bridge. At present, the most commonly used method is the plumb bob measurement, but the plumb bob measurement process is very susceptible to the influence of the external environment and can be easily blown off by the wind, resulting in deviations in the test results and affecting the test accuracy. Therefore, the efficiency of plumb bob detection is not high.

[0003] The document with prior art publication number CN 219640942 U provides a bridge column verticality detection device, which can detect the verticality of the column more intuitively and accurately through a naturally drooping connecting frame and an arc-shaped slide rail. At the same time, the spirit level on the connecting frame can ensure that the connecting frame is always perpendicular to the ground, further improving the detection accuracy.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the device needs to be fixed on the beam column through a mounting frame when in use. The outer diameter of the beam column is relatively large, so the outer diameter is also relatively large. At the same time, columns with different outer diameters require different mounting frames, which increases the transportation burden, occupies a large space, and is inconvenient to carry and use.

[0005] In view of this, we propose a bridge pile verticality detection device. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The purpose of the present application is to provide a bridge pile verticality detection device, which solves the technical problems in the above-mentioned background technology and achieves the technical effect of reducing space occupancy and facilitating portability.

[0008] 2. Technical solution

[0009] The technical solution of the present application provides a bridge pile verticality detection device, comprising: an annular frame, on which a plurality of height-adjustable support feet are distributed in an annular manner, a support frame is fixedly mounted on the annular frame, a vertical correction mechanism is rotatably connected to the support frame, and a vertically arranged laser pen is fixedly mounted on the vertical correction mechanism.

[0010] By adopting the above technical solution, the supporting state of the annular frame is fine-tuned by the supporting feet. Under the action of gravity, the vertical correction mechanism rotates freely on the supporting frame and maintains a parallel state with the vertical line. At the same time, the laser pen is driven to be parallel to the vertical line. The laser pen is turned on and against the bottom of the column. The light of the laser pen is projected upward, and multiple detection points are selected around the column. When the light beam of the laser pen is projected onto the column, it indicates that the column is tilted, which is convenient for quickly detecting the verticality of the pile body, occupies little space and is easy to carry.

[0011] As an optional solution of the technical solution of this application document, the support foot is threadedly connected to the annular frame.

[0012] By adopting the above technical solution, the supporting foot is a long screw rod and is threadedly connected to the annular frame, so that the supporting foot can be adjusted by rotation to fine-tune the overall supporting state of the annular frame.

[0013] As an optional solution of the technical solution of this application document, the vertical correction mechanism includes a sphere, an L-rod fixed vertically to the sphere, and a plumb bob fixed on the sphere and colinear with the L-rod, and the laser pen is vertically fixed on the L-rod.

[0014] By adopting the above technical solution, the vertical rod of the L rod, the plumb bob and the sphere are in the same line, and the horizontal rod of the L rod is vertically fixed to the laser pen. When the plumb bob is parallel to the vertical line, the light beam projected by the laser pen is parallel to the vertical line.

[0015] As an optional solution of the technical solution of the present application document, the support frame includes a fixing rod fixed on the annular frame and a ball ring fixed on the fixing rod, and the round ball is adapted to rotate with the ball ring.

[0016] By adopting the above technical solution, the ball ring is a two-petal structure that is welded and fixed to each other, and the openings at the upper and lower ends are smaller than the outer diameter of the ball to prevent the ball from falling from the ball ring. Then, under the action of gravity, the plumb bob pulls the ball to rotate in the ball ring to achieve automatic vertical correction of the laser pen.

[0017] As an optional solution to the technical solution of the present application document, a locking screw that abuts against the ball is threadedly connected to the ball ring.

[0018] By adopting the above technical solution, the locking screw and the ball are abutted against each other, so that the laser pen after vertical correction can be fixed in strong wind weather to prevent the laser pen from swinging.

[0019] 3. Beneficial effects

[0020] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0021] 1. The present application adjusts the entire annular frame by rotating and adjusting multiple supporting feet, and then places the detection device close to one side of the column. Under the action of the gravity of the plumb bob, the vertical rod of the L-rod is pulled parallel to the vertical line, and the horizontal rod is perpendicular to the vertical line, so that the light beam projected by the laser pen is finally parallel to the vertical line. Finally, the laser pen is brought close to the column, and then multiple positions of the column are detected in a circular manner, thereby achieving the technical effect of reducing space occupancy and facilitating carrying.

[0029] Reference Figure 1-Figure 4 The supporting state of the annular frame 1 is fine-tuned by the supporting feet 2. Under the action of gravity, the vertical correction mechanism 4 rotates freely on the supporting frame 3 and maintains a parallel state with the vertical line, while driving the laser pen 5 to be parallel with the vertical line. The laser pen 5 is turned on and against the bottom of the column. The light of the laser pen 5 is projected upward, and multiple detection points are selected around the column. When the light beam of the laser pen 5 is projected onto the column, it indicates that the column is tilted, which is convenient for quickly detecting the verticality of the pile body, occupies little space and is easy to carry.

[0033] Reference Figure 3 The vertical rod of the L rod 402, the plumb bob 404 and the sphere 401 are collinear, and the horizontal rod of the L rod 402 is vertically fixed to the laser pen 5. When the plumb bob 404 is parallel to the vertical line, the light beam projected by the laser pen 5 is parallel to the vertical line.

[0035] Reference Figure 1 and Figure 2 The ball ring 301 is a two-petal structure that is welded and fixed to each other, and the openings at the upper and lower ends are smaller than the outer diameter of the ball 401 to prevent the ball 401 from falling from the ball ring 301. Then, under the action of gravity, the plumb bob 404 pulls the ball 401 to rotate in the ball ring 301 to achieve automatic vertical correction of the laser pen 5.
