Problems solved by technology
The traditional safety shelters are demolished by truck cranes or tower cranes, but these cranes will hinder the operation safety of existing lines, and the demolition of the station safety shelters is limited by the space on the construction site, making it impossible to allow large cranes to enter the site Auxiliary construction, which has a great impact on the demolition of the safety shelter

Embodiment Construction
[0029] First make as image 3 Shown a frame, makes 4 altogether, and frame is welded by track tooling tire frame girder 3 and track tooling tire frame column 5. The width of the bottom of the frame is 3200mm, the width of the top is 4000mm, and the height of each layer is 1120mm, 1900mm, 1900mm, 2180mm and 1620mm. The support bar 6 is set at the midpoint of the main beam 3 of the horizontal track tooling tire frame. The support bar 6 is made of round steel pipe with a specification of φ89x4, the same as below. The penultimate layer is set at 3200mm, and the bottom layer is 1007mm, 1600mm and 2194mm respectively. Set up support rods.
[0030] The 4 frames obtained in the previous step are welded and connected by the main beam 3 of the tire frame of the longitudinal track tooling, with an interval of 3000mm, and a total of three spans of 9000mm; Figure 7 structure shown.
[0031] On the 5 sides of the track tooling frame column of the formed structure, a cantilever crane 2 i...

The invention relates to a quick dismantling method for a safety protective shed of an overpass high-speed railway operation line. Firstly, quick dismantling devices of the safety protective shed of the overpass high-speed railway operation line are manufactured and mounted; when safety protective shed roof panels and longitudinal secondary beams are dismantled, through moving of the quick dismantling devices on the two sides of the protective shed on a railway, components such as the dismantled protective shed roof panels and secondary beams are manually moved to the quick dismantling devicesto be disassembled and outwards transported; and when transverse primary beams are dismantled, through cantilever cranes on the quick dismantling devices, the primary beams are horizontally moved toa reserved operating platform of a nearby station building to be disassembled. According to the quick dismantling method, the problem that the spaces of certain actual construction sites are insufficient and thus the cranes cannot be used is solved, operation is easy, and the construction efficiency is high.
Description
technical field [0001] The invention relates to a device for removing a safety protection shed, in particular to a method for quickly removing a safety protection shed on an upper-span high-speed rail operation line. Background technique [0002] Due to the increase of railway lines, it is inevitable to encounter the situation of building new buildings across existing lines from above. This is especially common at stations where multiple lines meet. The usual practice is to set up safety shelters on existing lines. Setting up a safety shed can prevent the construction of adjacent or upper-span projects from affecting the normal operation of existing lines. At present, the construction of safety sheds on the existing lines in normal operation on the upper span is mainly for installation and construction, but as a temporary structure, the safety shed must be dismantled after the construction is completed. The traditional safety shelters are demolished by truck cranes or tower...
