Embodiment Construction

[0036] The following is attached Figure 1-4 The application is described in further detail.

[0037] The embodiment of the present application discloses a swivel system across a railway bridge. refer to figure 1 , a swivel system of a cross-railway bridge includes a spherical joint lower support 1 arranged on the ground, a swivel spherical joint 2 installed on the spherical joint lower support 1, and a spherical joint installed on the swivel spherical joint 2 The upper support 3, the swivel bridge 4 poured on the upper support 3 of the spherical joint, and the counterweight balance device 5 arranged on the lower surface of the swivel bridge 4.

[0038] The swivel bridge 4 includes a short bridge body 42 arranged at one end of the upper bearing 3 of the spherical hinge and a long bridge body 41 arranged at the other end of the upper bearing 3 of the spherical hinge. The long bridge body 41 and the short bridge body 42 are integrally poured with reinforced concrete After com...

Abstract

The invention relates to the technical field of bridge construction, in particular to a swivel system crossing a railway bridge. The system is characterized by comprising a spherical hinge lower support arranged on the ground, a rotating body spherical hinge arranged on the spherical hinge support, a spherical hinge upper support arranged on the rotating body spherical hinge, a rotating body bridge arranged on the spherical hinge upper support and a balance weight balancing device arranged below the rotating body bridge; wherein the spherical hinge upper support is located on one side of the center of the swivel bridge, the swivel bridge comprises a long bridge body and a short bridge body, the balance weight balancing device is arranged below the short bridge body, and the balance weightbalancing device is used for keeping the long bridge body and the short bridge body balanced. The balance weight balancing device arranged below the short bridge body can balance the moment of force at the two ends of the swivel spherical hinge, so that the tensile stress on the swivel bridge is uniformly distributed, and the swivel bridge is uniformly deformed.

Description

technical field [0001] The present application relates to the technical field of bridge construction, in particular to a swivel system for crossing railway bridges. Background technique [0002] Bridge swivel construction is a more popular bridge construction method in modern times. It is widely applicable to various types of bridge construction, especially for bridge construction under special conditions such as crossing existing lines, deep trenches and canyons. The obvious advantage of small range and short time. The common bridge swivel construction is to divide the whole span of the bridge or divide it into two half-spans from the middle span, set the turntable rotation system at the appropriate position, and then prefabricate according to the principle of symmetrical balance. After the prefabrication is completed, the center of gravity of the rotation system basically falls on the turntable rotation At the center, use the traction device to turn the turntable to horiz...
