Embodiment 1

[0032] This embodiment provides a bridge inspection car leveling device, such as figure 2 shown, including:

[0033] The bridge inspection vehicle respectively includes a truss maintenance platform 1 and a gantry 9 surrounding the outside of the truss maintenance platform 1; a connecting piece 2, which is movably connected above the gantry; a walking beam 3, the connecting piece 2 The position is variably connected to the walking beam 3, and the walking beam 3 is driven by the running mechanism 4 to drive the connecting piece 2 to make the bridge inspection vehicle move along the extending direction of the track 8;

[0034] At least one damper 5 is connected between the walking beam 3 and the gantry, and the buffer device is used to drive the The truss inspection platform 1 is used to stabilize the truss inspection platform 1 in a horizontal state.

[0035] Specifically, as figure 2 As shown, the damper 5 is connected to the left side of the truss inspection platform 1, a...

Embodiment 2

[0041] This embodiment is made on the basis of Embodiment 1. In this embodiment, the damper is replaced with a lead screw elevator 6. When the door frame 9 rotates synchronously with the walking beam 3, the lead screw The elevator 6 drives the truss maintenance platform 1 to rotate to a horizontal state by adjusting its own length.

[0042] Specifically, when the truss maintenance platform 1 tilts, the lead screw elevator 6 performs an elongation or shortening action consistent with the relative movement trend of the truss maintenance platform 1 relative to the walking beam 3 .

[0043] As a connector, the screw lift 6 can drive the synchronous movement of the walking beam 3, the gantry, and the truss maintenance platform. When the walking beam 3 tilts, the truss maintenance platform 1 will also tilt accordingly. At this time, the screw lift 6 can adjust its own length, so that the raised part of the truss maintenance platform 1 gradually becomes horizontal under the drive of ...

Embodiment 3

[0048] This embodiment provides a bridge inspection equipment, including at least two groups of bridge inspection vehicle leveling devices described in Embodiment 1 or 2, the bridge inspection vehicle leveling devices of the two groups are arranged in parallel to each other, and the bridge inspection vehicle leveling devices of each group are The car leveling device is connected with a track 8 respectively.

[0049] As a modification, the bridge inspection equipment may have a bridge inspection vehicle leveling device in Embodiment 1 and a bridge inspection vehicle leveling device in Embodiment 2 at the same time.

[0050] In this embodiment, at least one set of lifting and maintenance platforms is arranged inside the truss maintenance platform of the bridge inspection vehicle leveling device. When the height of the maintenance personnel cannot touch the box girder, the maintenance personnel stand on the lifting maintenance platform, and the lifting maintenance platform is rai...

Abstract

The invention provides a bridge inspection vehicle leveling device and bridge inspection equipment. As a buffering device is arranged in the bridge inspection vehicle leveling device, the buffering device can apply an acting force to a portal frame when a truss overhauling platform is inclined, the portal frame drives the truss overhauling platform so that the truss overhauling platform can slowlyrecover to the horizontal state; therefore, when a running mechanism moves to a steep slope position, the truss overhauling platform is prevented from shaking to cause injuries of operation workers within the truss overhauling platform and on a lifting overhauling platform and affect equipment within the truss overhauling platform and on the lifting overhauling platform.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a leveling device for a bridge inspection vehicle. Background technique [0002] The bridge inspection vehicle is a kind of work platform that can provide bridge inspection personnel during the inspection process. It is equipped with bridge inspection instruments and is used for mobile inspection and maintenance operations. [0003] The bridge inspection vehicle includes a truss maintenance platform for accommodating operators and operating equipment, and a gantry surrounding the outer side of the truss maintenance platform for driving the movement of the truss maintenance platform. [0004] There are usually two parallel tracks at the bottom of the bridge, and each track is provided with a set of running gear, and the two sets of parallel running gear move synchronously to drive the truss maintenance platform to run along the direction of the track extension. In the pr...
