AI Technical Summary
In the existing technology, rutting measurement relies on traditional tape measures and rulers, which have low measurement accuracy and cannot accurately describe the rutting shape, and require two people to work together.
A handheld rapid road rutting measurement device was designed, which included a directional double-wheel set, a pull-rod displacement sensor, a cable, a fixing buckle, a handle, a mobile power supply, and a data collector. The pull-rod displacement sensor was moved up and down on the road surface, and combined with the data collector, rapid and accurate rutting depth measurement was achieved.
It can quickly and accurately measure the road rutting depth without a ruler. The device is compact and portable, easy to operate, and greatly improves measurement efficiency.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rutting measurement, and in particular relates to a handheld road rutting rapid measuring device. Background Art
[0002] Road rutting is an important indicator that directly affects the comfort and safety of vehicles during driving. It is also an important factor affecting the service performance and service life of the pavement structure. The detection of rutting depth can provide important data information for decision makers to adopt what kind of road repair and maintenance plans.
[0003] Current rutting measurements primarily use traditional tape measures or rulers, supplemented by a 3m ruler, and typically require two people to complete the measurement. However, visually determining the maximum rutting depth results in low measurement accuracy and cannot accurately describe the rutting shape. Utility Model Content
[0004] In order to solve the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides a handheld road rutting rapid measuring device.
[0005] The handheld road rutting rapid measuring device includes a directional double wheel set, a pull rod displacement sensor, a cable 1, a cable 2, a fixing buckle, a handle, a mobile power supply and a data collector;
[0006] The fixing buckle is a single-sided opening buckle. The pull rod type displacement sensor is placed vertically into the fixing buckle and fixed. The pull rod of the pull rod type displacement sensor can move up and down in the vertical direction; the bottom of the pull rod is rotatably connected to the directional double wheel group; the cable 1 connects the mobile power supply and the pull rod type displacement sensor, and the cable 2 connects the data collector and the pull rod type displacement sensor.
[0007] The bottom of the pull rod is provided with a threaded section, and the central axis of the directional double wheel set is provided with a threaded opening matching the threaded section.
[0008] The fixing buckle is made of aluminum alloy, and a handle is welded on one side of the fixing buckle.
[0009] This handheld rapid road rutting measurement device, designed for rapid, continuous acquisition and accurate measurement of road rutting depth, eliminates the need for a 3m ruler. The device can be quickly assembled and disassembled, is compact and lightweight, and is easy to carry and operate, significantly saving time and improving measurement efficiency.

[0014] Example 1
[0015] The handheld road rutting rapid measurement device includes a directional dual-wheel assembly 2, a pull-rod displacement sensor 4, a cable 1, a cable 2, a fixing buckle 5, a handle 6, a mobile power supply 9, and a data collector 10. The fixing buckle 5 is a single-sided opening buckle. The pull-rod displacement sensor 4 is vertically inserted into the fixing buckle 5 and fixed. The pull rod 3 of the pull-rod displacement sensor can move vertically up and down. The bottom of the pull rod 3 has a threaded section, and the central axis of the directional dual-wheel assembly 2 has a matching threaded opening. The bottom of the pull rod 3 is rotatably connected to the directional dual-wheel assembly 2. The cable 1 connects the mobile power supply 9 and the pull-rod displacement sensor 4, and the cable 2 connects the data collector 10 and the pull-rod displacement sensor 4. The fixing buckle 5 is made of aluminum alloy, and the handle 6 is welded to one side of the fixing buckle 5.
[0016] When using the above-mentioned handheld road rutting rapid measurement device, the device is placed on the road surface 1, and the handle 6 is held to keep the fixed buckle of the device and the upper part of the fixed pull-rod displacement sensor 4 horizontal. The handle 6 is pushed to keep the device moving at the same level on the road surface 1. The directional double-wheel group 2 moves up and down with the shape of the road rutting, and at the same time drives the pull rod 3 to move up and down. The pull-rod displacement sensor 4 measures the movement data of the pull rod 3, and then obtains the road rutting depth data.
[0017] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. It should be understood by those skilled in the art that, without departing from the spirit and principles of the present invention, the present invention may be further modified and simply replaced, and these modifications and replacements will also fall within the scope of protection of the present invention as defined by the submitted claims.
