A cyclic maintenance device for prefabricated box girder of viaduct

Abstract

The invention relates to a cycle curing device for a prefabricated box girder of a viaduct. By means of the cycle curing device, the problem of wasting of water resources caused by the incapability ofrecovering the water resources in the curing process of an existing box girder is effectively solved. According to the technical scheme, the cycle curing device comprises a water tank; the left sideand the right side of the water tank are each connected with a spray pipe; a planetary gear train structure is arranged at the bottom of the water tank; a motor is connected to a sun gear; a planet carrier is connected with a planet wheel; a transverse shaft is arranged on each of the left side and the right side of the planet carrier; the rotation of the planet carrier can drive the transverse shafts on the two sides to rotate; a transverse plate is fixed above each transverse shaft; first gears are rotatably connected to the transverse plates; the rotation of the transverse shafts can drivethe first gears to rotate; the outer side of each first gear is engaged with a rack; a water collecting box which can slide in the length direction of the rack is arranged on the outer side of each rack; the water collecting boxes communicates with the water tank; a rope is fixed to the front end surface and the rear end surface of each water collecting box; and the other end of each rope go roundthe rack end on the corresponding side and then fixed to the corresponding transverse plate.

Description

technical field [0001] The invention relates to the field of bridge maintenance equipment, in particular to a cyclic maintenance device for viaduct prefabricated box girders. Background technique [0002] Prefabricated box girders are an important part of viaducts. Box girders usually need to be prefabricated in the girder factory. The prefabricated box girders are placed side by side in the girder factory. This is convenient for transportation and maintenance. During the maintenance of the girder, the box girder needs to be sprayed with water. Because the upper plane of the box girder is horizontal to store water, it is more convenient to maintain, but the left and right sides are inclined and have a large arc, which is not easy to store water. During maintenance, continuous water spraying is required to ensure that the water stays on the box girder for a sufficient time to improve the quality of maintenance, but long-term water spraying is a great waste of water resources,...
