Problems solved by technology

[0004] The existing detection methods have the following defects: (1) The maintenance inspection frequency is relatively low; (2) The evaluation is performed once a year; (3) Manual inspection is performed during daily maintenance. Considering safety issues, it is generally carried out in the middle of the expansion joint for a long time to fine-tune the disease. Sometimes it is difficult to find the disease in time; (4) The maintenance personnel cannot directly check the model of the expansion joint, the replacement process, the estimated cost, the stock of materials, etc.

Embodiment 1

[0100] This embodiment provides an accurate decision-making system for the timing of expansion joint maintenance, including a driving system, a data acquisition module, and an analysis and decision-making system. Such as Figure 5 and Figure 7 As shown, in the present embodiment, the data acquisition module includes: control system 2, laser displacement testing device 4, high-definition image acquisition device 5, infrared temperature sensing device 33, wireless transmission module (including remote control and data transmission antenna 8 and wireless network card 9), storage device (such as removable storage medium 13), power supply device 19, solar panel 1 and remote control system, etc. The control system 2, the laser displacement testing device 4, the high-definition image acquisition device 5 and the infrared temperature sensing device 33 are arranged on the top of the telescopic support arm 14 (linear type), and the bottom of the telescopic support arm 14 is fixed on t...

Embodiment 2

[0104] Such as Figure 3 ~ Figure 6 As shown, on the basis of Embodiment 1, the driving walking system also includes a detachable structure, including four lateral wheels 17 and a detachable telescopic support frame 22 . One end of the detachable telescopic support frame 22 is fixedly connected with the support frame connecting rod 23, and the other end is movably connected with the lateral wheels 17; The corner of the detachable telescopic support frame 22 is provided with a support mechanism 21 and a fixed movable spring 20 to ensure that the lateral wheels 17 clamp the anti-collision guardrail.

[0105] The drive walking system of this embodiment mainly regards the bridge anti-collision barrier as a track, walks along the anti-collision barrier, can move forward and backward, the four lateral wheels play a fixed role, and the four wheels on the top play a supporting and driving role. effect. The movable spring of the support mechanism is mainly to ensure that the side whe...

Embodiment 3

[0108] Such as Figure 8 As shown, on the basis of Embodiment 2, the linear telescopic support arm 14 is replaced with an L-shaped one.

Abstract

The invention relates to an expansion joint maintenance opportunity accurate decision-making system and method, and belongs to the technical field of highway, municipal road and bridge detection. The decision-making system comprises a driving walking system, a data acquisition module and an analysis decision-making system; the data acquisition module comprises a high-definition image acquisition device, a laser displacement testing device, an infrared temperature sensing device, a wireless transmission module, a control system and a storage module; the analysis decision-making system judges the disease type of an expansion joint through data analysis; comprehensive calculation is carried out to obtain whether maintenance or replacement is needed or not, if maintenance is needed, the maintenance content is accurately analyzed, and expansion joint information is obtained according to the bridge or road section number and the expansion joint position number; and then according to the disease type of the expansion joint, the damage volume and the raw material consumption for maintenance or replacement of the expansion joint are calculated. Various diseases of the expansion joint can be dynamically and accurately collected in real time, and dynamic monitoring and early warning are achieved.

Description

technical field [0001] The invention belongs to the technical field of highway, municipal road and bridge detection, and relates to a precise decision-making system and method for expansion joint maintenance timing. Background technique [0002] After highways, municipal roads or bridges are completed and put into use, routine inspections must be done regularly to ensure traffic safety. Routine inspection of roads, municipal roads or bridges includes inspection of expansion joints of roads, municipal roads or bridges. [0003] There is currently no decision-making system specific to the timing of bridge expansion joint maintenance. The existing maintenance method manually detects the bridge expansion joint disease, manually judges the timing of replacing parts, and then inquires about the component model and so on. There is currently no decision-making system specific to the timing of bridge expansion joint maintenance. [0004] The existing detection methods have the fol...
