Abstract

The invention provides a beam bridge walking part compensation device which comprises two adjacent side walking parts, at least one side walking part is a part of a beam bridge walking part, a preset telescopic part is arranged between the adjacent walking parts, and a compensation part covering the preset telescopic part is arranged between the adjacent walking parts. The width of the compensation part completely or partially covers the width of the preset telescopic part between the adjacent walking parts; the length of the compensation part is greater than the telescopic length of the preset telescopic part between the adjacent walking parts; the two ends of the compensation part are connected with the walking parts on the two sides in a supporting mode. At least one end of the compensation part horizontally rotates relative to the walking part on one side, and the rotation angle is smaller than 90 degrees; the walking parts on the two sides and the compensation part are provided with walking faces located on the same plane. After improvement, the preset telescopic part of the beam bridge is large in adjusting distance, still has a flat walking plane under the condition of large temperature difference change, and can keep the overall precision after being used for a long time.

Description

technical field [0001] The present application relates to the technical field of road traffic, in particular to a compensation device for the running part of a girder bridge. Background technique [0002] The existing road traffic system generally includes road traffic or rail traffic. No matter what kind of traffic system, it will set up a transition connection area due to the phenomenon of thermal expansion and contraction, so as to adapt to the adjustment of the running surface of the road or track due to thermal expansion and contraction. The phenomenon of approaching or moving away, such as using various connection devices to deal with. [0003] The existing compensation device, as shown in patent No. CN201911047599, is to adapt to the thermal expansion and contraction of the girder bridge by setting a movable plate between two fixed plates, and the relative sliding of the two fixed plates on the movable plate, but the movable plate will In the case of rising or moving...
