Embodiment

[0023] This embodiment is basically as figure 1 , figure 2 , image 3 and Figure 4 Shown:

[0024] A bridge 13 lifting type swivel system, comprising a lower pier 1 and an upper pier 2, the top of the lower pier 1 is integrally formed with a rectangular fixed column 5, the bottom of the upper pier 2 is provided with a cavity, and the upper pier 2 passes through the cavity The top of the lower pier 1 is evenly provided with four lifting chambers 4 in a circular array, and a hydraulic system 3 (such as an electric jack) is arranged in the lifting chamber 4. The output end of the hydraulic system 3 is connected to the upper pier. The bottom ends of 2 are offset; the side wall of the lower pier 1 is distributed with four grooves 16 in a circumferential array, and the grooves 16 are respectively connected with the corresponding lifting chamber 4; vertical connecting grooves 7 are arranged on the inner wall of the cavity, and the upper The side walls of the piers 2 are provide...

specific Embodiment approach

[0025] After the upper pier 2, the lower pier 1 and the bridge 13 are poured and formed, the hydraulic system 3 in the bridge 13 needs to be raised to start, and the hydraulic system 3 pushes the upper pier 2 to slide upward until the bottom of the bridge 13 is higher than the tops of the remaining bridges 13 , close the hydraulic system 3; use the hydraulic system 3 such as a jack to pull the traction cable, start the booster hydraulic device 11 to push the fixed rod 17, and boost the winch 10, thereby driving the winch 10 to rotate, and the winch 10 then drives the bridge 13 to rotate, and through infrared rays The cooperation between the receiver and the infrared emitter ensures that the trapezoidal groove 15 and the trapezoidal portion 14 between adjacent bridges 13 are in the right position.

[0026] Start the hydraulic system 3 in the raised bridge 13, and the hydraulic system 3 drives the upper pier 2 to slide down until the adjacent bridge 13 is parallel, at this time, ...

Abstract

The invention relates to the field of bridge construction, and specifically discloses an elevating bridge swivel system, which includes a lower pier and an upper pier, the top of the lower pier is fixed with a rectangular fixed column, the bottom of the upper pier is provided with a cavity, and the upper pier passes through The cavity is slidingly connected to the fixed column; the top of the lower pier is evenly provided with four lifting chambers in a circular array, and a hydraulic system is installed in the lifting chamber, and the output end of the hydraulic system is offset against the bottom of the upper pier; A winch with a traction cable is connected in rotation, and a swivel drive device for driving the winch is arranged on the top of the upper pier; a bearing platform is fixed on the top of the winch, and a bridge is fixed on the bearing platform; one end of the bridge is provided with a trapezoidal trapezoidal groove, and the bridge A trapezoidal portion corresponding to the shape of the trapezoidal groove is fixed at the other end of the trapezoidal groove.

Description

technical field [0001] The invention relates to the field of bridge construction systems, and specifically discloses a lift-type bridge swivel system. Background technique [0002] The bridge swivel construction method refers to a construction method in which the bridge is cast or assembled at a position deviated from the design, and then the bridge is rotated into place by means of power. This method can overcome terrain restrictions, the construction does not affect the traffic, it is convenient for prefabrication, and the construction is rapid, so it is more and more widely used. [0003] However, in the prior art, when the bridges are rotated and spliced, a large gap needs to be reserved between adjacent bridges. After the rotation is completed, it is necessary to re-concrete and seal it, which greatly prolongs the construction period. Contents of the invention [0004] The purpose of the present invention is to provide a lifting bridge swivel system to solve the prob...
