Description

Technical Field

[0001] The utility model relates to the technical field of height detection equipment for corrugated steel guardrail plates, in particular to a center height detector for corrugated steel guardrail plates. Background Art

[0002] The corrugated guardrail is a combined corrugated plate movable steel guardrail used at the opening of the central isolation belt of a highway. It is usually used on both sides of the highway and is usually fixed to each other by bolts and connected to a support column fixed to the ground at one end by bolts.

[0003] Currently, when detecting the center height of the corrugated steel guardrail plate in the corrugated guardrail, one person needs to align a leveling staff with the center position of the corrugated steel guardrail plate. After the first person aligns with the center of the corrugated steel guardrail plate and keeps it horizontal, another person then uses a steel tape measure to measure the center height of the corrugated steel guardrail plate. Theoretically, this measurement method is feasible. However, in actual operation, since the equipment is suspended and purely leveled manually, the error is very large. Moreover, measuring the center height of the corrugated steel guardrail plate with a steel tape measure by the naked eye is inaccurate, and it is also very difficult to ensure that the staff holding the leveling staff does not shake during the measurement process, further increasing the error. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the utility model provides a center height detector for corrugated steel guardrail plates, which solves the problem of large detection errors caused by the difficult cooperation of manual operations when measuring the center height of corrugated steel guardrail plates in the prior art.

[0005] According to the technical solution of the utility model, a center height detector for corrugated steel guardrail plates includes a connecting rod. A slider is slidably connected to the middle of the connecting rod. A slideway for the vertical passage of the connecting rod is provided in the slider. Clamping rods are rotatably connected to both ends of the connecting rod. A locking mechanism is connected between the clamping rod and the connecting rod. A clamping member is fixedly connected to the end of the clamping rod away from the locking mechanism. A first laser rangefinder is provided on the side of the slider facing the corrugated steel guardrail plate, and a second laser rangefinder is also provided on the vertical bottom surface of the slider.

[0006] The technical principle of the present utility model is as follows: Each time of detection, first rotate the clamping rods located at both ends of the connecting rod to clamp them on the upper and lower ends of the corrugated steel guardrail plate. While the locking mechanism locks the two clamping rods on both sides, adjust the connecting rod to keep the connecting rod as vertical as possible. Subsequently, use the first laser rangefinder on the slider facing the corrugated steel guardrail plate to measure the distance between the detector and the corrugated steel guardrail plate, and gradually slide the slider. When reaching the farthest distance, that is, between two waves of the corrugated steel guardrail plate, the first laser rangefinder on the slider facing the corrugated steel guardrail plate is exactly at the central position of the corrugated steel guardrail plate. Then, use the second laser rangefinder installed at the bottom end of the slider to measure the height from the ground. This data is the central height of the corrugated steel guardrail plate. In this way, it solves the problem of large detection errors caused by the difficult cooperation of manual operation in measuring the central height of the corrugated steel guardrail plate in the prior art.

[0007] Compared with the prior art, the present utility model has the following beneficial effects: By setting a slider that can slide in the vertical direction and a first laser rangefinder fixed on the surface facing the corrugated steel guardrail plate, and installing clamping rods and a locking mechanism at both ends of the connecting rod, now only one person can operate, avoiding the problem of inaccurate measurement results caused by difficult cooperation and various limitations of visual measurement during manual detection. Now only one person can operate, which solves the problem of large detection errors caused by the difficult cooperation of manual operation in measuring the central height of the corrugated steel guardrail plate in the prior art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] The technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] As Figures 1-3 shown, an embodiment of the present utility model provides a central height detector for a corrugated steel guardrail plate, which includes a connecting rod 1. A slider 2 is slidably connected in the middle of the connecting rod 1. A slideway 3 for the vertical passage of the connecting rod 1 is provided in the slider 2. Clamping rods 4 are rotatably connected to both ends of the connecting rod 1. A locking mechanism 5 is connected between the clamping rods 4 and the connecting rod. A clamping member 6 is fixedly connected to the end of the clamping rod 4 away from the locking mechanism 5. A first laser rangefinder 8 is provided on the side of the slider 2 facing the corrugated steel guardrail plate 7, and a second laser rangefinder 9 is also provided on the vertical bottom surface of the slider 2.

[0017] Specific operation process: Each time of detection, first rotate the clamping rods 4 at both ends of the connecting rod 1 to clamp the upper and lower ends of the corrugated steel guardrail plate 7. While the locking mechanism 5 locks the two clamping rods 4, adjust the connecting rod 1 to keep the connecting rod 1 as vertical as possible. Then use the first laser rangefinder 8 on the side of the slider 2 facing the corrugated steel guardrail plate 7 to measure the distance between the detector and the corrugated steel guardrail plate 7, and gradually slide the slider 2. When reaching the farthest distance, that is, between two waves of the corrugated steel guardrail plate 7, as Figure 1 shown, the first laser rangefinder 8 on the side of the slider 2 facing the corrugated steel guardrail plate 7 is exactly at the central position of the corrugated steel guardrail plate 7. Then use the second laser rangefinder 9 installed at the bottom end of the slider 2 to measure the height from the ground. This data is the central height of the corrugated steel guardrail plate 7. By providing the slider 2 that can slide in the vertical direction and the first laser rangefinder 8 fixed on the side facing the corrugated steel guardrail plate, and installing the clamping rods 4 and the locking mechanism 6 at both ends of the connecting rod 1, it avoids the problem of inaccurate measurement results caused by the difficulties in cooperation during manual detection and various limitations of visual measurement. Now only one person can operate, solving the problem of large detection errors caused by the large difficulty in manual operation and cooperation when measuring the central height of the corrugated steel guardrail plate 7 in the prior art.

[0018] According to another embodiment of the present utility model, as Figure 4 、 5As shown in the figure, a central height detector for a corrugated steel guardrail plate. A rocker 10 is provided on the end face of the slider 2. The rocker 10 is connected to a fixing member 11. The first laser rangefinder 8 is arranged on the side of the fixing member 11 facing the corrugated steel guardrail plate 7, and the second laser rangefinder 9 is arranged on the vertical bottom surface of the fixing member 11. In this solution, the rocker 10 is divided into a spherical part and a control rod. The connection part with the end face of the slider 2 is the spherical part. The spherical part is clamped inside the end face of the slider 2, but the spherical part can rotate inside the slider 2. One end of the control rod close to the end face of the slider 2 is connected to the spherical part, and the other end of the control rod is connected to the fixing member 11. This is because even if the connecting rod is not adjusted to the vertical state, as long as the fixing member is adjusted to be perpendicular to the corrugated steel guardrail plate 7, the orientations of the first laser rangefinder 8 and the second laser rangefinder 9 can be kept unchanged during the process of sliding the slider 2. Subsequently, the first laser rangefinder 8 on the fixing member 11 facing the corrugated steel guardrail plate surface is used to measure the maximum distance between the detector and the corrugated steel guardrail plate 7, and the slider 2 is gradually slid. When the maximum distance is reached, that is, between two waves of the corrugated steel guardrail plate 7, the first laser rangefinder 8 on the fixing member 11 facing the corrugated steel guardrail plate surface is exactly at the central position of the corrugated steel guardrail plate 7. Then, the second laser rangefinder 9 installed at the bottom end of the fixing member 11 is used to measure the height from the ground. This data is the central height of the corrugated steel guardrail plate 7.

[0019] According to an embodiment of the present invention, as Figure 1 shown, a central height detector for a corrugated steel guardrail plate. A level 12 is further installed on the top surface of the fixing member 11. In this solution, the level 12 can facilitate the staff to detect in real time whether the fixing member 11 remains horizontal during the process of sliding the slider 2. If the fixing member 11 does not remain horizontal or is not perpendicular to the corrugated steel guardrail plate 7, it can be adjusted to be perpendicular by rotating the rocker 10 manually.

[0020] According to an embodiment of the present invention, as Figure 1 、 2 shown, a central height detector for a corrugated steel guardrail plate. The locking mechanism 5 includes a connecting member 501 and a locking member 502. The connecting member 501 is a screw rod, and the locking member 502 is a nut. The head of the connecting member 501 is fixedly connected to the connecting rod 1, and the locking member 502 is rotatably connected to the connecting member 501. One end of the clamping rod 4 close to the connecting rod 1 is located between the head of the connecting member 501 and the locking member 502. In this solution, the connecting rod 1 uses the connecting member 501 to hinge the clamping rod 4 to meet the clamping function. At the same time, a locking member 502 is arranged on the connecting member 501, and when it is screwed towards the head of the connecting member 501, it clamps the clamping rod 4 to keep the clamping action.

[0021] According to an embodiment of the present utility model, as Figure 2 shown, a center height detector for a corrugated steel guardrail plate, the rotating connection part of the clamping rod 4 near the connecting piece 501 is a closed through hole, and the diameter of the closed through hole is larger than the diameter of the connecting piece 501. In this solution, since the diameter of the closed through hole is larger than the maximum diameter of the screw part of the connecting piece 501, it can meet the rotation condition on the connecting piece 501.

[0022] According to an embodiment of the present utility model, as Figure 1 shown, a center height detector for a corrugated steel guardrail plate, the clamping member 6 is a barb, and rough surfaces are provided at the clamping parts on both sides of the barb. In this solution, one end of the barb is pointed and can be inserted between the corrugated steel guardrail plate 7 and its fixed bottom column. The clamping member 6 and the clamping rod 4 can make the detector firmly clamp the corrugated steel guardrail plate 7. And a rough surface is provided on the surface of the barb to increase the friction between the corrugated steel guardrail plate 7 and the barb, which can prevent the clamping rod 4 from falling off during the clamping process. In this solution, the barb can also be replaced with other clamping structures, such as hinged clips, and the clips clamp both sides of the corrugated steel guardrail plate 7 to achieve the fixing effect.

[0023] According to an embodiment of the present utility model, as Figure 3 shown, a center height detector for a corrugated steel guardrail plate, a threaded hole 13 is provided on the end face of the slider, the threaded hole 13 is vertically communicated with the slideway 3, and a clamping member 14 is docked with the threaded hole 13. In this solution, the staff can make the bottom of the clamping member 14 abut against the connecting rod 1 by screwing the clamping member 14 into the threaded hole 13, so that the slider 2 cannot slide, realizing the locking function of the slider 2.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and all of them should be covered by the scope of the claims of the present utility model.
