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 ...

The device is characterized by comprising a base plate, wherein the base plate is in contact connection with a bearing plate, the base plate is fixedly connected with a direction changing gear ring, the direction changing gear ring is meshed with a direction changing planetary gear, the direction changing planetary gear is meshed with a direction changing sun gear, the direction changing sun gear and a direction changing servo motor are connected, the bearing plate is in rotatable connection with a rotation gear ring, the rotation gear ring is meshed with arotation gear, the rotation gear is connected with a rotation servo motor fixedly connected with the bearing plate, the rotation gear ring is fixedly connected with a rotation disc, the rotation discis in rotatable connection with a hydraulic telescopic arm, a front end of the hydraulic telescopic arm is in rotatable connection with a platform which can be absorbed on the underside of the bridge, and two sides of the bearing plate are respectively fixedly connected with two hydraulic legs. The device is advantaged in that operation is simple and convenient, the automatic and intelligent degree is high, work efficiency of detection is improved, and high practicality is achieved.

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...
