Description
Technical Field
[0001] The utility model relates to the technical field of measurement assistance, in particular to a measurement assistance tool for road and bridge construction. Background Art
[0002] Bridge and road measurement refers to the measurement work carried out in the various stages of bridge survey and design, construction and operation. Comprehensive crack tester. This type of instrument is mainly used for crack depth detection and crack width detection in bridges, tunnels, walls, concrete pavements, metal surfaces, etc., as well as storage of images of the measured cracks. The total station electronic rangefinder is a high-tech measuring instrument that integrates optics, machinery and electricity. It is a surveying and mapping instrument system that integrates horizontal angle, vertical angle, distance and height difference measurement functions. These measurements can measure road and bridge data. When using these measuring equipment, auxiliary tools are required to reduce the workload of staff.
[0003] The prior art discloses a measuring auxiliary tool for road and bridge construction with application number CN202221093945.9. The measuring auxiliary tool for road and bridge construction can automatically adjust the height of the top support plate through a lifting component, so that the staff can measure different positions and make it more convenient for the staff to use. The internal measuring equipment can be conveniently fixed through the fixing component, and equipment of different sizes and categories can be fixed at the same time, which is convenient for the staff to use it.
[0004] However, due to the uneven road surface of the road and bridge construction site, there may be potholes or slopes. When there are many potholes in the measuring site, it is easy for the device to be placed unevenly and easily tip over. When the measuring site is a slope, the device is not easy to fix under the action of the universal wheel, and it is easy to slip. The slope will also cause the measuring instrument to tilt, which will affect the accuracy of the measurement. Secondly, when the measuring instrument needs to adjust the measuring angle, the entire device needs to be moved. On the one hand, the operation is more difficult. On the other hand, due to the terrain restrictions of the site, the entire device may not be able to be placed stably after moving and adjusting, which is of poor practicality. Secondly, in order to meet the construction deadline, many works need to be carried out in the hot sun and rainy days. Under the exposure of the hot sun, the internal temperature of the measuring instrument will rise sharply, and the high temperature will cause the measuring instrument to suspend work or be damaged. Secondly, on rainy days, rain will fall on the measuring instrument, which is easy to cause water to enter the inside of the measuring instrument, and rain will remain on the lens of the measuring instrument, making the lens blurred and affecting the operation.
