Description

Technical Field

[0001] This utility model relates to the field of road inspection, specifically to an instrument for detecting the cross-sectional dimensions of drainage ditches on highways. Background Technology

[0002] Currently, the cross-sectional dimensions of drainage ditches along highways are mostly measured at intervals using steel tape measures. Highways are generally long, and using traditional measuring tools and methods is labor-intensive and inefficient. Because the collected data is scattered rather than continuous, if points are not taken at locations where dimensions are inappropriate, some unsuitable sections will be missed. Therefore, traditional measurement methods are inaccurate, prone to omissions, and prone to errors due to manual measurement.

[0003] Therefore, in order to solve the above-mentioned problems, an instrument for detecting the cross-sectional dimensions of highway drainage ditches is proposed. Utility Model Content

[0004] This invention addresses the problems mentioned above by designing an instrument for detecting the cross-sectional dimensions of highway drainage ditches. The device can be placed inside the drainage ditch. By moving a mobile vehicle, the side rod is moved to conform to the side wall of the ditch. When the side wall is uneven, the side rod will move inward or outward, and the deformation monitoring device will record the deformation, thus proving that the side wall of the ditch is uneven.

[0005] To achieve the above objectives, this utility model provides an instrument for detecting the cross-sectional dimensions of highway drainage ditches, comprising: a mobile vehicle, a supporting base rod, side rods, a connecting rod device, and a deformation monitoring device. The bottom of the mobile vehicle is equipped with a support base rod that can be telescopically adjusted in length. Both ends of the support base rod are rotatably connected to the side rods. The connecting rod device is a telescopic rod structure, and both ends of the connecting rod device are rotatably connected to the side rods on both sides. The deformation monitoring device is mounted on the connecting rod device.

[0006] By adjusting the length of the support rod as described above, both ends can be close to the side wall of the drainage ditch. The side rod is tilted and attached to the side wall by gravity. When the moving vehicle moves forward, the side rod will move when the side wall is uneven. At this time, it will drive the connecting rod device to extend or retract. The detection device records data through electrical signals under the deformation of the connecting rod device.

[0007] Furthermore, the linkage device includes a sleeve rod and a plug rod, the plug rod being slidably connected in the sleeve rod, and the ends of the sleeve rod and the plug rod being rotatably connected to the side rods on both sides respectively.

[0008] Furthermore, the deformation monitoring device includes a recording device and a transmission device. The recording device is mounted on the sleeve rod, and the transmission device is mounted on the insertion rod. The transmission device is slidably connected to the recording device.

[0009] Furthermore, the recording device includes: a recording plate, a protective cover, a conductive plate, a slide rail, and a signal receiver. The recording plate is installed on the side of the sleeve rod. The recording plate is provided with a slide rail. Two conductive plates are provided inside the slide rail. The protective cover is fixedly connected to the recording plate and covers the outside of the slide rail. The two conductive plates are respectively connected to the signal receiver through wires. The end of the transmission device is slidably connected inside the slide rail.

[0010] Furthermore, the transmission device includes: a mounting plate, a support column, a slide rod, a long slot, and a pin. The mounting plate is fixedly connected to the insert rod, and the mounting plate has a long slot. The support column is connected to the long slot of the mounting plate through the pin. The slide rod is fixedly connected to the top of the support column, and the end of the slide rod is slidably connected to the side of the recording device.

[0011] In the above manner, when the side rod moves, it drives the sleeve rod and the insertion rod to move, resulting in relative displacement. The slide rod moves in the slide rail and touches the conductive plates on both sides. The signal receiver is connected to the conductive plates through wires. The conductive plates on the same side are not connected to each other. The slide rod connects the conductive plates on the upper and lower sides, and the circuit is connected to generate an electrical signal.

[0012] Furthermore, it also includes a guide seat, which is fixedly connected to the inner wall of the end of the protective cover. Ball bearings are rotatably connected to both the inner wall of the sleeve rod and the guide seat, and the insert rod is slidably connected to the ball bearings.

[0013] Furthermore, it also includes an auxiliary device, one end of which is fixedly connected to the support column, and the other end is rotatably connected to the bottom of the protective cover.

[0014] Furthermore, the auxiliary device includes: a support plate, a bracket, and a movable wheel. The support plate is fixedly connected to both sides of the support column, the bracket is fixedly connected to the support plate, and the movable wheel is rotatably connected to the end of the bracket. The movable wheel is in rolling connection with the bottom surface of the protective cover.

[0015] Furthermore, the supporting base rod includes: a main rod, a secondary rod, an adjustment groove, and a positioning rod. The main rod is provided with a positioning rod, and the secondary rod is provided with an adjustment groove. The positioning rod is slidably connected in the adjustment groove to realize the relative sliding of the main rod and the secondary rod.
