Description

Technical Field

[0001] The utility model relates to a fully automatic micro-penetration vehicle for geotechnical engineering detection. Background Art

[0002] With the progress of urbanization, the technical requirements of various municipal engineering and housing construction projects are getting higher and higher. In the construction of construction projects, the stability of the foundation determines the stability of the superstructure. Usually, the foundation construction is a hidden project. If there are problems in the later stage, it is quite complicated to deal with. Therefore, foundation testing is the premise to ensure the quality of the construction project and is one of the indispensable and important links in the entire construction process. Micro-penetration instrument is one of the commonly used foundation testing methods. The traditional testing method is that the operator carries the instrument to randomly select the test points in the site, presses the micro-penetration instrument into the soil by manpower, and records the results. The detection efficiency is low, and a lot of human resources are required. It is difficult to cover the entire site with detection points. At the same time, it is greatly affected by the individual differences of the operators. Even the penetration speed and penetration degree of the same operator are difficult to maintain consistency each time, which has a great impact on the final results. The fully automatic micro-penetration vehicle involved in the utility model uses a radio remote control to control the micro-penetration vehicle to move freely. When the micro-penetration vehicle reaches the detection point and records the measured coordinates, the closed-loop stepper motor drives the pressure rod to penetrate the micro-penetration probe into the soil, ensuring that the penetration speed during the detection is uniform and the penetration degree meets the requirements, avoiding errors caused by individual operation differences. The micro-penetration vehicle has a simple overall structure and is easy to operate, which greatly reduces the input of manpower and increases the accuracy of detection. Summary of the invention

[0003] In order to solve the above-mentioned deficiencies, the utility model provides a fully automatic micro-penetration vehicle for geotechnical engineering detection.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: the main components of the fully automatic micro-penetrating vehicle include a vehicle-mounted instrument platform, a small crawler walking system and a supporting cylinder. The vehicle-mounted instrument platform is welded on the small crawler, and the supporting cylinder is installed in the center of the vehicle-mounted instrument platform. A bracket that can slide up and down is arranged inside the supporting cylinder. The pressure rod is connected to the sliding bracket in the supporting cylinder through a thread. The closed-loop stepper motor installed on the sliding bracket can drive the bracket to slide up and down. The closed-loop stepper motor can be controlled by a radio remote control, so that the micro-penetrating probe can be uniformly pressed into the soil to be detected through the reserved circular hole on the vehicle-mounted instrument platform to realize data collection. A data recorder, a spare probe box, and a battery box are placed around the vehicle-mounted instrument platform. The battery box provides power for the small crawler walking system. The data recorder is used to record the data collected by the micro-penetrating probe. Two different spare probes are placed in the spare probe box to facilitate the switching of probes between different soil bodies. At the same time, a window is arranged at the lower part of the supporting cylinder near the micro-penetrating probe 9 to facilitate the calibration and replacement of the probe.

[0005] Most of the components of the fully automatic micro-penetration vehicle, including GPS, small crawler walking system, closed-loop stepping motor, and radio remote control, can be made of mature components available on the market. The on-board instrument platform, supporting cylinder and bracket can be made of common metal and alloy materials, as long as they have sufficient rigidity. The modification is relatively easy. The micro-penetration instrument probe and data acquisition instrument can be purchased from the instrument manufacturer.

[0006] The utility model has the characteristics of simple structure, strong operability, practical functions and the like. BRIEF DESCRIPTION OF THE DRAWINGS
