Embodiment 1

[0049] by attaching figure 1 and 2 It can be seen that the present invention relates to a bridge pier maintenance and detection operation device for railway bridges, which includes a portal frame 1 connected with a horizontal truss and shaft trusses on both sides, a main frame 2 is suspended under the portal frame, and the main frames 2 on both sides are lowered. The slewing mechanism 3 and the maintenance and inspection work platform 4 are respectively connected, and it is characterized in that the maintenance and inspection work platform 4 is a two-stage cantilever structure, and the maintenance and inspection work platform 4 is divided into two sections, which are hung on the main frames on both sides respectively. 2, and can be rotated relative to the main frame 2 to form a two-part rotatable operating arm 5. When the rotatable operating arm 5 passes through the bridge pier, it rotates around the bridge pier to realize maintenance and testing around the bridge pier under t...

Embodiment 2

[0053] The structure of the second embodiment is basically the same as that of the first embodiment. It is a railway bridge around the pier maintenance inspection device, including the gantry connected by the horizontal truss and the shaft truss on both sides. A main frame is suspended under the gantry, and the main A slewing mechanism and a maintenance and inspection work platform are respectively connected under the frame. It is characterized in that the maintenance and inspection work platform is a two-stage cantilever structure, and the maintenance and inspection work platform is divided into two sections, which are respectively hung under the main frames on both sides. And it can rotate relative to the main frame to form a two-part rotatable operating arm. When the rotatable operating arm passes through the bridge pier, it can rotate around the bridge pier to realize the maintenance and inspection work around the bridge pier under the bridge.

[0054] It’s just that the sl...

Embodiment 3

[0056] Embodiment 3 has basically the same structure as Embodiment 1. It is a railway bridge pier-wrapping operation device for repairing and testing around pier, which includes a gantry connected by horizontal trusses and shaft trusses on both sides. A main frame is suspended under the gantry, and the main A slewing mechanism and a maintenance and inspection work platform are respectively connected under the frame. It is characterized in that the maintenance and inspection work platform is a two-stage cantilever structure, and the maintenance and inspection work platform is divided into two sections, which are respectively hung under the main frames on both sides. And it can rotate relative to the main frame to form a two-part rotatable operating arm. When the rotatable operating arm passes through the bridge pier, it can rotate around the bridge pier to realize the maintenance and inspection work around the bridge pier under the bridge.

[0057] It’s just that the slewing mec...

Abstract

The invention discloses a pier-bypassing railway bridge maintenance and detection method and device. A portal alternate walking type maintenance and detection system using trimmer beams under guardrails on the two sides of the high-speed railway bridge as walking and working fulcrum is adopted; rotary working arms are arranged on the two sides of the lower surface of a walking part of the portal alternate walking type maintenance and detection system respectively, and pier-bypassing maintenance and detection work is conducted through rotation of the rotary working arms. By the adoption of the device, various kinds of maintenance and detection work below bridges can be completely achieved, bridge maintenance and detection can be conducted uninterruptedly under the condition that the high-speed rail runs normally, all work requirements of high-speed railway bridge maintenance and detection are met, and working efficiency is high.

Description

technical field [0001] The invention relates to a method and device for maintenance and detection of railway infrastructure, in particular to a method and device for maintenance and detection of a railway bridge to ensure the normal and safe operation of the railway bridge, and belongs to the technical field of detection and maintenance of railway infrastructure. [0002] Background technique: [0003] When building a railway, it often encounters rivers, valleys, highways or crosses with another railway. In order for the railway to cross these terrain obstacles, various railway bridges need to be built. Therefore, railway bridges are on the railway line. important parts of. Especially with the rapid development of high-speed railways, my country's high-speed railway bridges have been widely used in high-speed railways. The main characteristics of my country's high-speed railway bridges are: bridges account for a large proportion of lines, and there are many multi-span viaduct...
