Box girder outer side mold plate loading and unloading trolley and mold plate loading and unloading method thereof

Abstract

The invention discloses a box girder outer side mold plate loading and unloading trolley and a mold plate loading and unloading method thereof. The trolley comprises a trolley frame, a moving mechanism, a longitudinal hydraulic jack, a lateral hydraulic jack and a vertical hydraulic jack; bearing plates are arranged on two opposite sides of the top of the trolley frame and can make translation inthe horizontal direction; the moving mechanism is installed on the trolley frame and is for driving the trolley frame to move longitudinally and horizontally and turn; the longitudinal hydraulic jackis hinged on the trolley frame; the longitudinal hydraulic jack is connected with the bearing plates in a hinged mode for driving the bearing plates to make longitudinal translation; the lateral hydraulic jack is hinged on the trolley frame; the lateral hydraulic jack is connected with the bearing plates for driving the bearing plates to make lateral translation; and the vertical hydraulic jack ishinged on the bearing plates and can stretch along the direction perpendicular to the top of the bearing plates. According to the scheme, aligning installation of a box girder outer side mold plate is simple and easy, and a dilemma existing according to the prior art is practically solved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a trolley for installing and disassembling formwork on the outer side of a box girder and a method for installing and disassembling formwork. Background technique [0002] Box girder is a kind of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, which is similar to a box, hence the name. [0003] When the prefabricated box girder adopts the block-assembled outer formwork to complete the box girder concrete pouring process at one time, the outer formwork needs to be installed and removed before and after the box girder concrete is poured. At present, gantry cranes or truck cranes are generally used for the installation and removal of the box girder block-assembled outer formwork. Due to the irregular shape of the formwork, it is difficult to control the posture of the formwork after lifting, and it is difficult to adjust the outer le...
