Bridge swivel support leveling device and leveling method thereof

Abstract

The invention discloses a bridge swivel support leveling device which comprises a jack, a height adjusting sliding block, a swivel support bracket and two sets of leveling bolts, the jack is fixed to a swivel support padstone, the height adjusting sliding block is arranged on the swivel support padstone and fixedly connected with a horizontal ejector rod of the jack, the top face of the height adjusting sliding block is an upper inclined face, and the height adjusting sliding block is arranged on the swivel support padstone and fixedly connected with a horizontal ejector rod of the jack. The bottom face of the rotating body support bracket is a lower inclined face, the middle of the rotating body support bracket is supported on the upper inclined face of the height adjusting sliding block, the two ends of the rotating body support bracket are each connected with a set of vertically-arranged leveling bolts, and the bottom end of each leveling bolt is supported on the rotating body support padstone. The working direction of the jack is adjusted to be horizontal pushing from vertical lifting through the height adjusting sliding block, the pushing force applied by the jack is far smaller than the gravity, borne by lifting, of the swivel support, the leveling bolt is introduced to serve as a supporting assembly, auxiliary construction of large machines such as a crane is omitted, the construction cost is reduced, and the construction efficiency is improved. And the mounting efficiency of the swivel support is improved.

Description

technical field [0001] The invention relates to the technical field of swivel bridges, in particular to a bridge swivel bearing leveling device and a leveling method thereof. Background technique [0002] With the acceleration of my country's modernization process and the increasing development of public transportation construction, in order to ease the urban traffic congestion, overpasses with upper and lower layers that do not interfere with each other in multiple directions are increasingly used in expressway interchange, urban expressways, and main roads. under construction. In the construction of bridges that need to cross existing roads and railways, the common construction techniques include hanging basket cantilever casting, steel pipe column support door openings and swivel bridge methods. Among them, because the swivel bridge transforms the operation above the obstacle into the operation on the shore or near the ground, it is widely used in the situation where the ...

Problems solved by technology

This leveling method has a long working cycle and cumbersome procedures.

For the construction of adjacent existing lines, the long-term working status of the crane will bring certain risks to the safe operation of the existing lines, and will cause large mechanical shift costs and labor costs, high costs, insufficient automation, and low efficiency. Delayed working hours

If the swivel support is leveled by placing the hydraulic jack below, since the height difference between the swivel support and the pad stone is small, and the swivel support needs to be placed in the pre-embedded bolt holes, it does not have the Space conditions for hydraulic jacks
