8. A method of constructing an installation for cross-track installation of railway accessories as claimed in any one of claims 1 to 7, comprising the steps of:
s1: according to construction requirements, placing auxiliary facilities on the center line of the box girder in advance according to the requirements of construction positions;
s2: the walking chassis of the paving equipment walks to the front of the attached facilities along the center of the bridge, so that the plate pile enters a lifting range; according to the requirements of cross operation, the rotary conveying arm is driven to rotate ninety degrees through rotation to cross the existing linear rail, and the equipment moves forwards 0.5 meter each time during paving to finish the paving of the auxiliary facilities;
s3: hoisting the front end of the trolley to take a plate, and hoisting the accessory facilities to a storage area of the walking chassis by adopting the hoisting trolley;
s4: grabbing the cover plate by a plate taking sucker, lifting to a designed safe height, and then translating to a position for placing a rotary conveying arm;
s5: the rotary conveying arm is used for conveying the cover plate to the front end; the positioning sucker takes a plate from the end part of the conveyor, and the plate is conveyed to a specified position through transverse conveying, longitudinal conveying and vertical conveying, and is aligned through manual adjustment;
s6: in the process of walking of the bearing chassis (3), the carrier (1203) is pushed through the transverse electric telescopic rod (1202) and then the supporting column beam (1204) is pushed through the walking balance piece (12) and the auxiliary component (13) until a limiting ball (1205) at the end part of the supporting column beam (1204) is contacted with the side wall of the trapezoidal base (2), then the vertical electric telescopic rod (1206) is started, the vertical electric telescopic rod (1206) pushes the balance roller (1208) to be contacted with the ground, in the process of walking of the bearing chassis (3), the supporting limitation of the supporting column beam (1204) is realized, the running of the bearing chassis (3) is ensured to be stable and straight, and the problem of route deviation generated during the laying work while moving is avoided; moreover, the vibration generated by the bearing chassis (3) in the moving process is buffered through the matching among the movable bearing block (1302), the balance spring (1303) and the arc-shaped plate (1308) arranged in the balance roller (1208), so that the bearing chassis has good stability; thereby ensuring the stability of the whole construction.
