Drawings

Fig. 1 is a schematic front view of an embodiment of the present invention;

fig. 2 is a schematic top view of an embodiment of the present invention;

the names of the parts corresponding to the numbers in the figure are respectively: the method comprises the following steps of 1-a movable platform, 2-a counterweight cabinet, 3-a connecting beam, 4-a connecting longitudinal arm, 41-a bearing part, 5-a sliding seat, 6-a pedestrian maintenance base, 7-a force-borrowing pull handle, 8-a protective fence, 9-a ladder stand, 10-a support column and an A-bridge.

Detailed Description

The invention will be further explained by means of specific embodiments with reference to the drawings, in which:

referring to fig. 1 and 2, an embodiment of a bridge maintenance construction structure, the schematic diagrams are only partially schematic and omit the construction structure of the whole section of bridge a, but it is sufficient to clearly understand the scheme, specifically includes a movable platform 1 and a plurality of sets of bearing mechanisms arranged along the length direction of the bridge a, each set of bearing mechanism includes two bearing units oppositely arranged on two sides of the bridge a in the width direction, and the movable platform 1 is located below the bridge a and is connected with the bearing units in a sliding manner. The bearing unit includes counter weight cabinet 2, connect crossbeam 3 and connect trailing arm 4, counter weight cabinet 2 is fixed on bridge A surface, connect crossbeam 3 fixed connection in counter weight cabinet 2 and level and extend to the bridge A outside, connect trailing arm 4 fixed connection in connect crossbeam 3 and follow the vertical bridge A below that extends to in the bridge A outside, counter weight cabinet 2 plays counter weight and guard action, it is also comparatively common in other bridge maintenance platforms, make and connect crossbeam 3, connect trailing arm 4, movable platform 1 can both be born by safety and stability. Connecting 3 lower parts of crossbeam still fixedly connected with fixes support column 10 on bridge A, and support column 10 generally selects to realize fixedly with bridge A both sides railing department, strengthens supporting connecting crossbeam 3, promotes the structural strength and the stability of bearing unit.

The connecting trailing arm 4 is in an L shape as shown in the figure, the horizontal block part at the lower end of the connecting trailing arm is the bearing part 41 of the connecting trailing arm, all the bearing parts 41 on each side are fixedly connected with a sliding seat 5 together, the sliding seat 5 is provided with a sliding rail, and the bottom of the movable platform 1 is provided with a pulley which is connected with the sliding rail in a sliding way.
