Description

Technical Field

[0001] This application relates to the field of measurement technology, specifically to a device for measuring the straightness of a highway corrugated guardrail. Background Technology

[0002] During highway construction, corrugated guardrails need to be installed on both sides of the highway. During and after installation, the straightness of the guardrails needs to be checked.

[0003] The traditional testing method involves randomly selecting a 20-meter section of guardrail. Two people at both ends pull the rope taut and attach it to the top and side of the guardrail. Another person visually estimates the maximum gap and measures it with a steel ruler. This maximum gap is the maximum measured value of straightness.

[0004] In actual straightness testing, the positions of the string and steel ruler need to be frequently adjusted. However, during these frequent adjustments, negligence or lack of skill on the part of the measuring personnel may lead to inaccurate measurement positions. Inaccurate measurement positions directly affect the straightness calculation results, resulting in inaccurate assessments. This may necessitate re-measurement or correction of existing data, increasing the complexity and uncertainty of the work.

[0005] Therefore, it is necessary to provide a device for measuring the straightness of highway corrugated guardrails to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figure 1 As shown, this application provides a device for measuring the straightness of a highway corrugated guardrail, including a bracket 2 and a measuring wheel 1 rotatably disposed between the lower ends of the bracket 2. The measuring wheel 1 has a diameter of 15.9 cm and a circumference of 50 cm, so as to further improve the accuracy of the measurement in the future.

[0032] Furthermore, a vertical telescopic rod 3 is fixedly installed on the upper end of the bracket 2. The vertical telescopic rod 3 is used to provide variables when measuring the longitudinal straightness of the guardrail. At the same time, a horizontal telescopic rod 4 is installed at the top of the vertical telescopic rod 3. The horizontal telescopic rod 4 is used to provide variables when measuring the lateral straightness of the guardrail.

[0033] Meanwhile, a sensor 6 is fixedly installed on one side of the measuring wheel 1, and a receiver 7 is installed at the lower end of the vertical telescopic rod 3. The sensor 6 and the receiver 7 cooperate with each other. The sensor 6 contacts the receiver 7 at the lower end of the vertical telescopic rod 3 to record data and transmit the data to the data processing system for analysis.

[0034] When it is necessary to test the longitudinal straightness of the guardrail, first place the measuring wheel 1 on the road surface, then place the horizontal telescopic rod 4 on the upper part of the guardrail, and finally push the entire device forward to make the measuring wheel 1 roll on the road surface. At this time, the vertical telescopic rod 3 will extend and retract due to the longitudinal undulation of the guardrail. After the measuring wheel 1 rotates once, the sensor 6 on the measuring wheel 1 will contact the receiver 7 installed on the vertical telescopic rod 3. At this time, the deformation of the vertical telescopic rod 3 is recorded. Push the measuring wheel 1 forward and record a deformation every 50cm. Finally, take the average value of all recorded deformations as the longitudinal straightness of the guardrail installation.

[0035] In order to measure the lateral straightness of the guardrail, a measuring arc plate 5 is detachably installed at the other end of the lateral telescopic rod 4. The arc and size of the measuring arc plate 5 match the size of the protruding end of the guardrail, and the measuring arc plate 5 can rotate 90° so that it can fit against the guardrail during the measurement process, further improving the stability of the measurement. When the measurement begins, the measuring arc plate 5 is first installed at the other end of the lateral telescopic rod 4 and made to fit tightly against the protruding end of the guardrail. Then, the measuring wheel 1 is pushed to move. At this time, the lateral telescopic rod 4 will deform due to the lateral bending of the guardrail. When the sensor 6 on the measuring wheel 1 and the receiver 7 on the vertical telescopic rod 3 come into contact, the deformation of the lateral telescopic rod 4 is recorded. The measuring wheel 1 is pushed forward and a deformation is recorded every 50cm. Finally, the average value of all recorded deformations is taken as the lateral straightness of the guardrail installation.

[0036] To address the issue of the measuring wheel 1 being obstructed by stones and other obstacles on the road surface during its movement, a leveling mechanism 8 is installed at one end of the support 2. Figures 1-3 As shown, the sweeping mechanism 8 is used to sweep away stones and sharp objects in the path of the measuring wheel 1.

[0037] The sweeping mechanism 8 includes a mounting bracket 80 fixedly mounted at one end of the bracket 2, a fixing rod 81 fixedly mounted at the other end of the mounting bracket 80, a mounting plate 82 fixedly mounted at the other end of the fixing rod 81, and a cover 83 fixedly mounted at the bottom end of the mounting plate 82.

[0038] Furthermore, a rotating shaft 87 is rotatably arranged inside the housing 83, and a small gear 86 is fixedly arranged on the rotating shaft 87 inside the housing 83, so that the small gear 86 can rotate inside the housing 83 along with the rotating shaft 87.

[0039] Meanwhile, a motor 84 is fixedly installed on the mounting plate 82. The output end of the motor 84 extends through the cover 83 into the interior and is fixedly connected to a large gear 85. The large gear 85 meshes with a small gear 86 so that the motor 84 can be started to drive the small gear 86 through the large gear 85 to drive the rotating shaft 87 to rotate.

[0040] Furthermore, the other end of the rotating shaft 87 extends through the cover 83 to the outside. A sweeping plate 88 is fixedly installed at the other end of the rotating shaft 87. The sweeping plate 88 is in direct contact with the ground to facilitate the movement of stones and obstacles on the subsequent cleaning route. The starting motor 84 drives the small gear 86 through the large gear 85 to rotate the rotating shaft 87, thereby causing the sweeping plate 88 to perform a fan-shaped swing operation. While swinging, the stones and obstacles are swept to both sides, thus achieving the effect of clearing obstacles on the route.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
