Abstract
The utility mode relates to a portable safety device of rock bar foundation ditch blasting excavation has solved the problem that the existence of current rock bar foundation ditch blasting excavation safety protection is wasted time and energy, the covering is fragile and the security alert scope is big. Including moving platform and walking capable track, be provided with high pressure nozzle in the moving platform, moving platform terminal surface from top to bottom all is provided with the protection network, is provided with away the road wheel below the moving platform left and right sides, is provided with a roll curtain around the moving platform above the both sides and receive and releases the waterwheel, and the book curtain is provided with protection network book curtain in receiving and releasing the waterwheel, and the lower extreme of protection network book curtain is provided with the tenesmus and personally experiences sth. Part of the body. The utility model has the advantages of reasonable design reliably, can effectively avoid among the foundation ditch blasting excavation process safety influence of popping rock around to to can reduce the pollution of blasting dust through high pressure spraying dust fall function, have simple structure, protecting effect is good, reuse rate is high and sets up and remove the fast advantage of protection.
Description
Technical field
This utility model relates to foundation ditch blasting safety protection device, is specially a kind of rock bar shaped foundation ditch Blasting Excavation moving type security preventer.
Background technology
Along with the construction of underground structures such as urban rail transit in China develops, subway station get more and more, subway station belongs to list structure, and being frequently run onto rock stratum during excavation needs to carry out Blasting Excavation.
Subway station is generally located on busiest section, city, and personnel, vehicle and building are the most intensive, causes security incident for preventing broken stone from splashing, and during explosion, phenomenon must take effective safety prevention measure.At present, mostly use and cover the covering methods such as straw mattress or straw bag (built-in a small amount of sand, soil), the big gun quilt of junked tire establishment, wire netting, and carry out a range of shotfiring safety warning.These safeguard procedures, exist that covering is fragile, Security alert scope big to some extent, affects the drawbacks such as the normal urban highway traffic of periphery, and workload is big, time-consuming, cost is high in covering simultaneously.
Summary of the invention
This utility model is in order to solve the problem that existing rock bar shaped foundation ditch Blasting Excavation security protection existence is wasted time and energy, covering is fragile and Security alert scope is big, it is provided that a kind of rock bar shaped foundation ditch Blasting Excavation moving type security preventer.
This utility model adopts the following technical scheme that realization: rock bar shaped foundation ditch Blasting Excavation moving type security preventer, intersect fixing mobile platform and the walking rails being arranged on the rock bar shaped foundation ditch left and right sides including by crossbeam and longeron, high-pressure nozzle it is provided with in mobile platform, mobile platform upper and lower end face is provided with protection network, mobile platform is provided with travelling wheel below the left and right sides, before and after mobile platform, both sides are provided above roller shutter folding and unfolding winch, being provided with protection network roller shutter in roller shutter folding and unfolding winch, the lower end of protection network roller shutter is provided with lower falling body.
When carrying out protecting operation, stop slungshot by protection network and protection network roller shutter and absorb slungshot energy, and light transmission is easy to operating area daylighting under foundation ditch；Moved by travelling wheel, carry out depositing dust after explosion by high-pressure nozzle simultaneously, overcome the protection of existing rock bar shaped foundation ditch exist waste time and energy, covering is fragile and Security alert scope is big problem.
This utility model reasonable in design is reliable, the slungshot security implication to surrounding during foundation ditch Blasting Excavation can be prevented effectively from, and can there is simple in construction by the pollution of High Pressure Spray for Dust Suppression function reduction blasting dust, protection effect is good, recycling rate of waterused is high and arranges and release the fireballing advantage of protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-crossbeam, 2-longeron, 3-walking rails, 4-high-pressure nozzle, 5-protection network, 6-travelling wheel, 7-roller shutter folding and unfolding winch, 8-protection network roller shutter, falling body under 9-.
Detailed description of the invention
Rock bar shaped foundation ditch Blasting Excavation moving type security preventer, intersect fixing mobile platform and the walking rails 3 being arranged on the rock bar shaped foundation ditch left and right sides including by crossbeam 1 and longeron 2, high-pressure nozzle 4 it is provided with in mobile platform, mobile platform upper and lower end face is provided with protection network 5, travelling wheel 6 it is provided with below the mobile platform left and right sides, before and after mobile platform, both sides are provided above roller shutter folding and unfolding winch 7, being provided with protection network roller shutter 8 in roller shutter folding and unfolding winch 7, the lower end of protection network roller shutter 8 is provided with lower falling body 9.
