Embodiment Construction
[0015] The present invention will be further described below in conjunction with the examples, and the purpose is only to better understand the content of the present invention.
[0016] The tunnel engineering train-type quick-lifting and folding work platform described in this embodiment uses the bottom plate 13 of the rail flat car as the installation base, and each section of the rail flat car is an independent operation unit, which can be combined arbitrarily to form multiple operation units.
[0017] Referring to the accompanying drawings, the main truss of the platform is composed of front and rear truss pieces and inter-column diagonal braces 20 connecting the front and rear truss pieces. And upper beam 15 adopts steel pipe to make, has vertical chute 12 on platform main truss column 8, and platform main truss column 8 upper end is hung with chain block 6 by welding lug plate 17. The lifting platform column 2 made of steel pipes is also set in the platform main truss co...

The invention relates to working platforms for railway tunnel defect treatment, in particular to a tunnel engineering train type rapid lifting and folding working platform. The working platform comprises track flat cars, a platform primary truss, a lifting platform and folding platforms, wherein the platform primary truss is fixed on a bottom plate of the track flat cars, lifting platform columns are sleeved on platform primary truss columns in a telescoping mode, and folding platform brackets are hinged on the platform primary truss columns. The working platform is installed and used with each section of track flat car serving as one unit, large-area construction can be performed within total lengths of trains, effective maintenance time can be fully utilized, the construction process can be accelerated, meanwhile, engineering trains advance and quit wholly, so that timely site removal can be guaranteed, on-schedule and safe operations of existing trains can be guaranteed, repetitive operation time can be reduced substantially, engineering costs can be saved, and the construction safety can be guaranteed.
Description
technical field [0001] The invention relates to a working platform for railway tunnel disease control and construction, in particular to a train-type rapid lifting and folding working platform for tunnel engineering. Background technique [0002] Railway tunnels that have been in operation for a long time will have different degrees of disease, especially for railway electrification reconstruction projects, where electric catenary is required in the tunnel, and the diseased tunnel must be comprehensively treated first. At present, the tunnel improvement generally adopts a disassembled simple working platform. The general structure of the platform is: a 2m×2m frame is made, and 4 small wheels are set under the frame to contact the top surface of the track, which can slide and move on the top surface of the track. Scaffold steel pipes are used to build a 1.8m×1.8m square working platform. The height of the platform is set up according to the working height. Usually, the two wo...
