Embodiment 1

[0039]Embodiment 1, the present invention is a bridge detection device, including a base plate 1, the base plate 1 is the basis of the device, and tires are connected to it in rotation on both sides, and the base plate 1 provides a fixed foundation for the subsequent structure through the contact between the tires and the ground. To facilitate the movement of the device, the side of the base plate 1 is fixedly connected with a ladder, so that the inspectors can board the device. It is characterized in that the load-bearing plate 2 is connected to the base plate 1, and the specific contact connection method can be A number of load-bearing columns are fixedly connected to the bottom plate 1, and the load-bearing plate 2 is placed on the load-bearing columns, or other common contact connection methods can be used. The direction-changing ring gear is fixedly connected to the bottom plate 1, and the The direction-changing ring gear is meshed with a direction-changing planetary wheel...

Embodiment 2

[0040] Embodiment 2. On the basis of Embodiment 1, this embodiment provides a specific structure in which the platform 10 is adsorbed on the lower surface of the bridge, so as to ensure that the platform 10 can be adsorbed on the lower surface of the bridge after reaching the specified position. Specifically, the The four corners of the platform 10 are fixedly connected with hollow columns 12, the upper ends of the four hollow columns 12 are connected with vacuum suction cups 13, and the four hollow columns 12 are fixedly connected to the lower end surface of the platform 10 through air pipes. The vacuum pump 14 is connected, and the height of the hollow column 12 should be higher than the average height of the human body, but at the same time its height should not be too high, because the height of the hollow column 12 is the distance between the platform 10 and the lower surface of the bridge, too far is not conducive to detection For the detection of personnel, the height of...

Embodiment 3

[0041] Embodiment 3, on the basis of Embodiment 1, this embodiment provides a specific structure of the hydraulic telescopic arm 9 to ensure that the hydraulic telescopic arm 9 can lift the platform 10 to the required position Specifically, the hydraulic telescopic arm 9 includes a bottom arm 15 rotatably connected to the turntable 8, a middle arm 16 is slidably connected to the bottom arm 15, and an upper arm is slidably connected to the middle arm 16. 17. The upper end of the upper arm 17 is rotatably connected to the platform 10. The bottom arm 15 and the middle arm 16 are hollow cylindrical structures with one end open. The middle arm 16 and the bottom arm 15 The inner surface is closely attached, the upper arm 17 is a solid cylindrical structure, the upper end of the upper arm 17 is rotatably connected to the platform 10, and when the hydraulic telescopic arm 9 needs to be extended, the bottom arm 15 Fill the interior with hydraulic oil. After the hydraulic oil fills the ...

Abstract

The invention relates to a bridge detection device, which effectively solves the problems of the existing detection device, such as serious shaking, high risk, low detection efficiency, no function of preventing tipping, and inconvenient steering; A load-bearing plate is connected, and a direction-changing ring gear is fixedly connected to the bottom plate. A direction-changing planetary gear is engaged in the direction-changing ring gear, and a direction-changing sun gear is meshed next to the planetary gear. The direction-changing sun gear is connected to the direction-changing servo motor. The load-bearing plate The upper rotation is connected with a rotating ring gear, and the rotating gear is meshed inside the rotating ring gear. The rotating gear is connected with the rotating servo motor fixedly connected to the load-bearing plate. The rotating ring gear is fixedly connected with a turntable. The front end of the hydraulic telescopic arm is rotatably connected to a platform that can be adsorbed on the bottom of the bridge, and two hydraulic outriggers are fixedly connected to both sides of the load-bearing plate; the invention is easy to operate, has a high degree of intelligence and automation, improves the working efficiency of detection, and has strong practicability .

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge detection device. Background technique [0002] With the development of transportation, the development of bridge construction, which is an important part of transportation, is advancing by leaps and bounds. In order to ensure the safety of traffic participants, after the bridge is completed and put into use, regular inspections must be carried out regularly. Routine inspection of bridges includes the inspection of the substructure of bridges. Periodic inspections of bridges are the conditions for assessing the health status of bridges, understanding and controlling the occurrence and development of bridge diseases, formulating reasonable maintenance plans, prolonging the service life of bridges and ensuring the safety of bridges in service. . The impact of bridge inspection vehicles on the safety of bridge inspection personnel, project cycle and traffic plays...
