Abstract
The utility model relates to a mobile electricity-shielding protective shed, which comprises a steel-structural roofing, frameworks assembled on both sides and electricity-shielding boards; wherein, traveling wheels are arranged on the lower ends of the frameworks; a mobile track is arranged under the traveling wheels; and the electricity-shielding boards are connected with the lower side of the roofing through electricity-shielding board suspenders. The mobile electricity-shielding protective shed resolves the problem on how to protect the existing railroad line during the cantilever-casting construction of each section of articulated beams, and avoids the construction of an ultra-long fixed electricity-shielding shed, therefore the safety and use flexibility of the electricity-shielding shed are improved, and meanwhile, the structure is simplified. The mobile electricity-shielding protective shed is characterized by safety, reliability, use flexibility and simple structure. The mobile electricity-shielding protective shed is widely applicable to safety protection in the construction of cast-in-place bridges and prefabricated hoisting bridges spanning electrified railway lines in operation, or other spanning structures.
Description
Affiliated technical field
The utility model relates to strides the safety protection equipment that uses on the electric railway business line on a kind of, the anti-electricity protection of especially a kind of packaged type frame.
Background technology
China's urban development is very rapid, because the infrastructure in early stage is not enough to the estimation of local economic development, a lot of cities all are faced with form, especially urban road that enlarging transforms and stand in the breach and transform in advance, thereby, stride the overpass bridge of railway on many and need build.Whole nation arterial railway main line has all become electric railway through nearly more than 10 years transformation, on stride construction of railways, the greatest problem that is faced is: fall arrest problem and anti-electric problem between operational period.These two problems do not solve, and construction safety and railway line up train safety can't guarantee.Common means of defence is: adopt a kind of fixedly gate-type steel work of cross-line, all-insulated plate is hung on steel work, on the gate-type structure ceiling is installed again, play the measure of anti-electricity and preventing dropped material.But the shortcoming of this structure: 1, can not integral hoisting, normally a Pin one Pin installs, and so, blocks main points often, and is bigger to the railway operation influence; 2, this fixed structure usually can not be applied in a flexible way in practice of construction.When the operation place was moved, mounted anti-electric frame was just ineffective, reinstalled after must removing, and perhaps will drop into corresponding increase with preventing that electric frame does very longly; 3, structure is comparatively complicated, and processing and installation difficulty are big.
Summary of the invention
Its purpose of the utility model just is to provide the anti-electricity protection of a kind of packaged type frame, for reducing the adverse effect of construction period to the railway operation, the use flexibility that improves anti-electric frame, make simple and directization of structure simultaneously, have safe and reliablely, use flexibly characteristic of simple structure.
The technical scheme that realizes above-mentioned purpose and take, comprise steel work roofing and the framework that is installed on both sides, and all-insulated plate, described framework lower end is provided with travelling wheel, the travelling wheel lower end is provided with moving track, and described all-insulated plate is connected the roofing lower end through the all-insulated plate suspension rod.
Compared with prior art this device has the following advantages.
1 owing to adopted the anti-electric scaffolding structure design of packaged type, not only solved because of the operating area change cause fixed anti-electric frame protection less than problem, also greatly reduce interference to the existing line driving, have simple for structurely, be easy to processing, lifting and move characteristics very easily.It is the good safeguard of striding the existing electrified railway construction.
2, owing to adopted the anti-electric scaffolding structure design of packaged type, thereby efficiently solve each sections of cantilever perfusion tie-beam construction period protection question, avoided having set up the fixed anti-electric frame of overlength existing line, whole construction course safety is smooth, obtains good effect.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure schematic front view;
Fig. 2 is this device frame structural representation front view;
Fig. 3 is the three-dimensional schematic views of this apparatus structure.
