Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to an infrared distance measuring engineering measurement ruler. Background Art

[0002] The infrared distance measurement engineering measuring ruler is an advanced road surface flatness detection equipment. It combines infrared distance measurement technology and precise measurement principles to accurately measure the flatness of the road surface. The design of this measuring ruler aims to improve measurement efficiency and accuracy and reduce the labor intensity of manual measurement, especially when conducting rapid and large-area road surface flatness detection. It is more advantageous and aims to overcome the limitations of traditional three-meter rulers and wedge-shaped feeler gauges or depth vernier calipers in terms of measurement accuracy and convenience, especially when dealing with large flatness differences on road surfaces or slopes.

[0003] The core technology of the infrared ranging engineering measuring ruler is based on the principle of infrared ranging. By emitting a beam of infrared light to the surface to be measured and receiving the light reflected from the surface, it can perform multi-point measurements on the road surface in a short time. By measuring the time difference between emission and reception, combined with the speed of infrared light, the distance between the light and the surface to be measured can be accurately calculated to obtain the height data of the road surface, that is, the length of the measuring ruler. This technology not only improves the measurement accuracy, but also effectively avoids the road surface damage that may be caused by contact in traditional measurement methods, and reduces the impact of environmental factors on the measurement results. Taking into account the needs of on-site measurement, the infrared ranging engineering measuring ruler is made of lightweight and durable materials, and is designed to be handheld or vehicle-mounted, which is convenient for rapid deployment and use in different locations.

[0004] The existing infrared distance measurement engineering measuring ruler is generally used to test the depth of the top surface of the ruler from the ground at the maximum gap position with a depth vernier caliper. The depth minus the ruler height is the height of the maximum gap at the test point. The problem of cumbersome measurement is being improved. For example, the infrared distance measurement engineering measuring ruler disclosed in the authorized Chinese patent CN212779111U can detect the distance from the ground within the entire ruler range through the use of structures such as the ruler body, cavity, side wall I, opening, infrared rangefinder, sliding rod, sliding member, push rod, side wall II, notch, spring pin and pin hole, so that the accuracy of the slope or road surface flatness measurement is improved. The flatness detection can be completed by gently pushing the push rod, thereby improving the efficiency of the operation and construction.

[0005] However, when using the infrared distance measuring engineering measuring ruler in the above cited document, the operator needs to push a push rod to complete the flatness detection. This operation method has obvious disadvantages. First, the infrared distance measuring technology itself is a high-precision measurement method, which can provide information such as distance and speed. However, when this technology is applied to the engineering measuring ruler, its advantages are not fully utilized. Manual operation means that a skilled operator is required for each measurement, which is not only time-consuming but also inefficient. It is impossible to achieve fast and continuous measurement. Due to the limited reaction speed and accuracy of humans, this directly affects the stability and accuracy of the measurement results. Secondly, manual operation lacks consistency. Due to differences in experience, skills and attention among operators, these factors will affect the accuracy of the measurement results, resulting in deviations in the measurement results. In addition, in the case of continuous operation or multi-person collaboration, the limitations of this manual operation are more obvious because it cannot be automated and standardized, thereby reducing work efficiency and measurement accuracy.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-3The utility model provides a technical solution: an infrared distance measurement engineering measuring ruler, comprising a driving and regulating box 1, a moving support foot 2, an anti-skid support foot 3, a push handle 4 and an infrared rangefinder body 6, one side of the push handle 4 is fixedly mounted on one side of the driving and regulating box 1 by bolts, the moving support foot 2 and the anti-skid support foot 3 are respectively fixedly mounted on the same side of the driving and regulating box 1 close to the ground by bolts, the number of the moving support foot 2 and the number of the anti-skid support foot 3 are both two, a horizontal moving mechanism 500 is installed in the driving and regulating box 1, and one side of the infrared rangefinder body 6 is installed on the horizontal moving mechanism 500;

[0033] It should be noted that the driving force assembly includes a servo motor 5021 and a rotating rod 5022; one side of the servo motor 5021 is fixedly mounted on one side of the driving control box 1, one end of the rotating rod 5022 is fixedly connected to the output shaft of the servo motor 5021, and the other end thereof penetrates the driving control box 1 and extends into the groove 503 to be connected to the gear transmission assembly, and the outer side of the rotating rod 5022 is rotatably connected to the inside of the driving control box 1 through a bearing so as to be able to stably drive the gear transmission assembly to rotate.

[0034] It can be understood that the gear transmission assembly includes a driving bevel gear 5041 and a follower bevel gear 5042; one side of the driving bevel gear 5041 is fixedly connected to an end of the rotating rod 5022 away from the servo motor 5021;

[0038] The inner wall of the driving control box 1 is provided with a limit groove 508 for the sliding adjustment block 5071 to slide against.
