Trolley for detecting surface evenness

Abstract

The invention discloses a trolley for detecting surface evenness. The trolley for detecting the surface evenness comprises a flat car. One end of the flat car is fixedly connected with a hanging hook.Two ends of the flat car are fixedly connected with two support bases and an iron sheet. Each support base is hinged with a telescopic cylinder. The opposite faces of a pair of the telescopic cylinders are fixedly connected with magnets. Each magnet corresponds to the iron sheet. A support rod is moveably inserted in a pair of the magnets. A telescopic rod is moveably inserted in the telescopic cylinder. One side, away from the magnet, of the telescopic cylinder is fixedly connected with a sleeve. An inserting rod is moveably inserted in the sleeve. One end, away from the sleeve, of the inserting rod passes through the telescopic cylinder and is extended into the telescopic rod. The telescopic rod is provided with multiple inserting holes corresponding to the inserting rods. The trolley for detecting the surface evenness is rational in structure, the flat car is used as a carrier, and multiple adjustable measuring cylinders are installed. In addition, the detection area is adjustable,the telescopic cylinders are foldable, the practicability is strong, and the popularization is easy.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a trolley used for detecting the smoothness of road surfaces. Background technique [0002] With the rapid development of my country's economy, the current development focuses on the periphery of big cities and villages. Among them, rural road construction is the largest and most important project in my country's current infrastructure construction. Road construction will definitely bring rural people Come for real sweetness. When multiple projects are carried out at the same time, it is inevitable that there will be road quality problems. The smoothness of the road surface is an important indicator of the road surface quality. In order to test the smoothness parameters, major manufacturers have developed and manufactured a variety of road leveling However, most of these devices are placed on the road for temporary detection, and then change the monitoring point, so the flexibili...

When multiple projects are carried out at the same time, it is inevitable that there will be road quality problems. The smoothness of the road surface is an important indicator of the road surface quality. In order to test the smoothness parameters, major manufacturers have developed and manufactured a variety of road leveling However, most of these devices are placed on the road surface for temporary detection, and then change the monitoring point, so the flexibility of the device is poor, because the detection of flatness itself is random sampling, and the device with poor flexibility will It makes the random sampling of inspectors more perfunctory, and even some road sections are directly omitted without inspection, so the quality of the road cannot be guaranteed
