Description

Technical Field

[0001] The utility model relates to the technical field of bridge beam bottom inspection vehicles, and more specifically, to a parking anchoring device for a bridge beam bottom inspection vehicle. Background Art

[0002] The bridge beam bottom inspection vehicle is a bridge maintenance and repair equipment that can move at the bottom of the bridge. Its structure is mainly composed of a truss platform, a drive component and an electronic control device. The whole vehicle relies on the drive component to hang on the beam bottom track to achieve free movement at the bottom of the bridge.

[0003] The traditional parking method of the inspection vehicle cannot park the inspection vehicle firmly in the parking position when encountering typhoons or extreme conditions with large bridge deck amplitude. Under the action of strong external forces, the parking device will be deformed and damaged, causing the inspection vehicle to slip on the track, resulting in accidents such as the vehicle body tilting or hitting the bridge pier;

[0004] The existing parking device for the bottom beam inspection vehicle mainly relies on the brake of the driving motor and the top rail screw installed on one side of the driving box to realize the parking of the inspection vehicle; wherein, the top rail screw is a parking device arranged on one side of the driving box, and a bolt with a friction head at the end is pressed against the track bottom plate through a threaded hole. The parking is mainly realized by the friction force generated by the friction head at the end of the screw and the track bottom plate. However, in typhoon weather or when the amplitude of the bridge deck is large, the friction force generated by the brake of the motor and the top rail screw cannot firmly fix the inspection vehicle on the track in the parking position. Under the action of strong external force, the top rail screw will be deformed or even broken.

[0005] In the prior art, the parking of the bottom beam inspection vehicle also uses a chain to lock the inspection vehicle bolt to the rail joint seat in the parking position. However, since the chain is a soft structure, in the event of a typhoon or when the bridge deck has a large amplitude, the connection position will be pulled back and forth due to the sliding of the inspection vehicle, eventually causing the chain to break. It is also impossible to reliably and effectively park the inspection vehicle in the parking position under extreme circumstances. Utility Model Content

[0050] Embodiment 2:

[0051] like Figure 3-Figure 4 As shown;

[0052] A parking anchoring device for a bridge beam bottom inspection vehicle 2, used for fixing the bridge beam bottom inspection vehicle 2 to a track 1, comprises a connecting plate 1 3 arranged on the bridge beam bottom inspection vehicle 2 and located on a side close to the track 1, a connecting plate 2 4 arranged on the track 1, and a fixed shaft 5 for connecting the connecting plate 1 3 and the connecting plate 2 4; the connecting plate 1 3 and the connecting plate 2 4 are respectively provided with holes used in conjunction with the fixed shaft 5.

[0053] In some possible implementations, the connecting plates 3 are installed on the box plate 21 of the driving box in the bridge inspection vehicle and are in two groups; the two groups of connecting plates 3 are symmetrically arranged along the long direction of the track 1.

[0054] In some possible implementations, in order to effectively enable the fixed shaft 5 to pass through the connecting plate 1 3 , the connecting plate 2 4 , and the box plate 21 , a through hole 1 is provided on the box plate 21 , which is coaxially connected to the hole on the connecting plate 1 3 .

[0057] The track 1 is an I-beam structure, including an upper flange, a track 1 web, and a lower flange;

[0058] The connecting plates 2 4 are in two groups and are symmetrically arranged along the long direction of the track 1; the two groups of connecting plates 2 4 are respectively arranged at the bottom of the track 1. There is a certain gap between the two groups of connecting plates 2 4, and a U-shaped groove structure is formed with the bottom of the track 1, so that the fixed shaft 5 and the track 1 have a connection point, and the connection is more stable and reliable;

[0059] Of course, the connecting plates 2 4 can also be arranged in three or more groups.

[0060] In some possible implementations, the connecting plate 3 is disposed below the track 1 .

[0061] In some possible implementations, in order to avoid running the vehicle without unlocking the bridge beam bottom inspection vehicle 2 and the track 1, causing damage to the inspection vehicle;

[0062] A parking sensor 6 for detecting whether the fixed shaft 5 is unlocked is also provided on the driving box of the bridge beam bottom inspection vehicle 2; the parking sensor 6 is interconnected with the driving system in the driving box.

If it is not unlocked, the drive system will issue an early warning and send an unlocking signal, and the operator will unlock the fixed shaft 5; then the drive system can control the bridge beam bottom inspection vehicle 2 to move along the long direction of the track 1; avoiding the direct start-up of the vehicle when the track 1 and the bridge beam bottom inspection vehicle 2 are not unlocked, causing damage to the vehicle;

[0068] The parking sensor 6 in the present invention can adopt a photoelectric proximity switch or a capacitive proximity switch in the prior art to identify the fixed shaft 5 .

[0069] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
