Problems solved by technology
[0004] See Figure 8, in the prior art, nickel-chromium wire with a frame is used for cutting after being energized on the construction site. The existing problems are that due to the large size of the foam board, the weight of the entire frame tool is large, the labor intensity is high, and The dimensional accuracy of the foam board is difficult to guarantee, which makes the operation of the subsequent pre-filling process more difficult, and there are also major safety hazards
Can not meet the requirements of engineering construction site processing

Embodiment Construction
[0030] like Figures 1~6 Among them, a foam board cutting device includes a portal frame 1 and a lifting cutting device 4, the lifting cutting device 4 is movably connected with the portal frame column 101 of the portal frame 1, and the lifting cutting device 4 is connected with a driving device that drives the lifting. , at least one nickel-chromium wire 5 is arranged at the bottom of the lifting and cutting device 4 , and the nickel-chromium wire 5 is electrically connected to the voltage regulating device 18 . The voltage regulating device 18 in this example is a commercially available product, which is used to step down the input voltage of 380V to a voltage of 36-110V, and adjust the current according to the processing amount. The main component is the transformer. The nickel-chromium wire 5 is made of Cr20Ni80. The foam block 10 is placed under the lifting and cutting device 4 , and the heated nickel-chromium wire 5 cuts the foam block 10 by descending the lifting and ...

The invention provides a foam sheet cutting device. The foam sheet cutting device comprises a portal frame and a lifting cutting device, wherein the lifting cutting device is movably connected with portal frame uprights of the portal frame and is also connected with a driving device for driving lifting; at least one nickel chrome wire is arranged at the bottom of the lifting cutting device and electrically connected with a voltage regulating device; side surface forming devices are arranged on two sides of the inlet position of the portal frame; and a top surface forming device is further arranged in the inlet position of the portal frame. Owing to the structure that the portal frame and the lifting cutting device are adopted, foam sheets can be cut very conveniently. The foam sheet cutting device is simple in structure and convenient to operate and can perform processing by use of materials and equipment on a construction site, and the labor intensity of processing is reduced. As the portal frame uprights serve as guide rails, the processing precision can be guaranteed.
Description
technical field [0001] The invention relates to a foam board cutting device, in particular to a foam board cutting device used in the construction of an elevated expressway. Background technique [0002] The bridge head of a planned branch road viaduct in the upper span of a highway is preloaded with an overload of 2m. The reconstruction method is as follows: a new ground express main line is built on the old road, the bridge head is located in the original overloaded preloaded road section, and the maximum filling height is about 3m. The settlement after empirical calculation does not meet the bridge head settlement control index. [0003] EPS board, also known as polystyrene foam board, is a white block made of expandable polystyrene beads containing a volatile liquid foaming agent and heated in a mold after pre-heating. Because this material has the advantages of light weight, shock resistance, drop resistance, heat insulation, sound absorption, heat preservation, self-...
