Problems solved by technology

[0004] In the case of short-term use, it is reasonable to use a bridge inspection vehicle instead of the beam bottom support platform, but under long-term construction conditions, it is obviously uneconomical to use a bridge inspection vehicle, especially when there are many obstacles on the side of the bridge, or the sidewalks on both sides of the bridge. When the width of the motorway exceeds 3.5m, the use of the bridge inspection vehicle is subject to many restrictions, which cannot meet the needs of normal construction. At this time, the hanger under the bridge or the fixed platform at the bottom of the beam are usually selected.
[0005] For porous expressway bridges and urban viaducts (most of which are ten-meter-level small hole span pier-column bridges, and some bridges have a length of several kilometers), when the large area of ​​​​the bottom of the beam is overhauled for a long time, ordinary hangers and bottom beams under the bridge The fixed platform is no longer suitable. The fixed platform is not easy to set up, and it cannot be turned around in a large range, which is not economical and not suitable; Suspenders, etc.) and bridge piers (columns) under the bridge, on the one hand, the hangers under the bridge cannot move continuously along the direction of the bridge, and it is usually necessary to install and remove the hangers once under the bridge. The under-bridge hanger cannot be installed with the help of lifting equipment. Obviously, the existing under-bridge hanger is not economical or suitable, and cannot meet the requirements of use.

Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0043] Such as Figure 1-4 As shown, a beam bottom maintenance platform capable of spanning bridge piers and obstacle columns of the present invention includes a column-span truss vehicle 4, a pier-span column hanger 5, a hoisting system 6 and a connecting unit 7, and the column-span truss vehicle 4 includes two pairs of The truss trucks 8 on the inside of the guardrails 2 on both sides of the bridge 1 can move along the direction of the bridge and are symmetrically arranged. The truss trucks 8 stick to the side of the guardrail and protrude four detachable cantilever rods 8.10. Each pair of truss trucks 8 The cantilever rods on the top are respectively hoisted by the hoisting system 6 to jointly lower the pier-span hangers 5, and...

Abstract

The invention belongs to the technical field of bridge engineering, and in particular relates to a beam bottom overhaul platform capable of spanning bridge piers and obstacle pillars and a use method of the beam bottom overhaul platform. The beam bottom overhaul platform comprises pillar spanning truss trolleys, pier pillar spanning hanging racks, hoisting systems and connecting units, wherein the pillar spanning truss trolleys comprise two pairs of truss trolleys which are positioned on the inner sides of guardrails on two sides of a bridge, are capable of moving in the direction of the bridge and are arranged in symmetry; a plurality of detachable cantilever rods stretch outwards from one side adhering to the guardrails, of each truss trolley; the pier pillar spanning hanging racks are suspended on the cantilever rods on each pair of the truss trolleys through the hoisting systems; adjacent pier pillar spanning hanging racks are connected through the connecting units; the pier pillar spanning hanging racks comprise a plurality of truss units which are arranged in the direction of the bridge; adjacent truss units are in detachable fixed connection. The beam bottom overhaul platform has the advantages of high applicability, simple operation, good security, good economic property, good application prospect and the like.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a beam bottom maintenance platform capable of crossing bridge piers and obstacle columns and a use method thereof. Background technique [0002] With the development of bridge construction in our country, nearly one million bridges in highways and cities have entered the stage of regular inspection and maintenance. And adapted construction platforms, for different bridge profiles, the existing construction platforms include beam bottom brackets, bridge inspection vehicles, bridge hangers and beam bottom fixed platforms. [0003] When the clearance under the bridge is low, it is better to use the beam bottom support, but when the clearance under the bridge is high, the use of the beam bottom support requires more supporting structures, which is obviously uneconomical and undesirable. [0004] In the case of short-term use, it is reasonable to use a bridge i...
