Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and the embodiment of civil construction I standard span first and second line traffic bridge engineering of the second line ship lock project of Xijin Water Conservancy Project.

[0025] Such as image 3 As shown, the No. 9 pier 90 to No. 8 pier 80 of the main bridge is constructed by the hanging basket cantilever pouring method. The span of No. 9 pier 90 to No. 8 pier 80 is 50m, and the cantilever pouring is 45m, which is divided into 12 pouring units. From the 1# pouring unit to the 12# pouring unit, the longitudinal centerline of the box girder bends from a straight line to the left into an arc, and the radius of curvature decreases from infinity to 50m.

[0026] Such as Figure 1 to Figure 5 As shown, the present invention includes a road wheel bracket 1, two main road wheel assemblies 2, a track 3 and two groups of steering wheel combinations 4, and the two main r...

Abstract

The invention discloses a steerable hanging basket traveling device, which comprises a traveling wheel bracket, two main traveling wheel assemblies, an H-shaped steel track and two sets of steering wheel combinations. The two sets of steering wheel combinations are arranged on the lower sides of corresponding main wheels. The lower sides of the two main wheels are supported on the upper side of the track. The lower side of the track is fixed on a box girder. Each steering wheel combination comprises a pair of steering wheels and steering wheel axial movement mechanisms, the end surfaces of thepair of steering wheels are oppositely horizontally arranged on the both sides of an H-shaped steel intermediate web, the outer peripheral faces of the steering wheels are abutted against the lower side face of an H-shaped steel top flange plate, and outer end screws of support shafts are connected with the steering wheel axial movement mechanisms fixed on the outer sides of vertical side plates.A steering method comprises the method of turning left and turning right. The device has a simple structure and is simple in method. The self-locking principle of the worm and worm gear transmissionis used, to make the support shafts to be locked in the required moving positions, so that the problem of steering on the arc-shaped track of the hanging basket traveling device is solved.

Description

technical field [0001] The invention relates to a hanging basket walking device for bridge cantilever box girder cast-in-place construction, in particular to a steering device used for hanging basket suspension trusses on arc-shaped tracks when moving, and belongs to the technical field of bridge construction. Background technique [0002] The hanging basket is a construction platform for high-altitude operations during the cantilever pouring of the box girder on the upper part of the bridge. It is suspended under the suspension truss, and the hanging basket walking device on the lower side of the suspension truss is supported on the track by the main traveling wheel in several traveling wheel brackets. After the cantilever box girder of a bridge has been poured and the concrete curing period has passed, the traveling device is driven by a jack to carry the suspension truss, hanging basket and bottom form support frame on the lower side of the suspension truss to the cantilev...
