Abstract
It the utility model is related to a kind of explosion-proof pipe for escaping end protective cover of rotor; include the hollow cone protective cover of integrally formed round and smooth arc-shaped head; flashing light is installed in the tapered middle inside of protective cover; four knobs are installed uniformly at intervals in the cone lateral wall of flashing light opposite side; dustcloth is pasted in cone lateral wall surrounding; four fixations are fixedly mounted with the cone inside edge of flashing light side to grab, and are formed with the middle part of four fixations are grabbed and are bent in an arc shape arc.Explosion-proof pipe for escaping end protective cover of rotor provided by the utility model is integrated the hollow cone protective cover for making circular arc head; how it can reflect away in the stone of pipe end of escaping; fully ensure that pipe safety; can be by fragile pipe for escaping edge; effectively prevent pipeline breaking caused by the surprise attack of rubble; means of escape is safer, ensures life channel.
Description
Technical field
The utility model belongs to protection field, more particularly to a kind of explosion-proof pipe for escaping end protective cover of rotor.
Background technology
The tunnel in tunnel and mine in the construction process, due to being influenced by complicated geology and other factors, happens occasionally
Landslide phenomenon, wherein landslide phenomenon consequence of closing the door is the most serious, once the life for occurring to seriously affect in-cavity construction personnel is pacified
Entirely.Therefore, for the phenomenon of caving in tunnel, constructing tunnel, to avoid personnel casualty accidents as far as possible, unnecessary warp is reduced
Ji loss, carries out the setting of tunnel pipe for escaping, it appears extremely important.
Required according to domestic associated documents, tunnel V grades of country rock paragraph and the ground that the high risk that collapses is in through risk assessment
Section and other locations are when enclosing rock measure adds up to deform more than 100mm, it is necessary to pipe for escaping are set, to ensure tunnel excavating process
The personal safety of middle construction personnel.Between secondary lining and face, face is not greater than away from the safe step pitch between inverted arch
Distance as defined in design and specification.Between tunnel tunnel face and secondary lining, pipe for escaping should be set, with excavation drilling depth not
Disconnected reach, pipe for escaping distance, which excavates face, should be not more than 20m, stretch into and applied inverted arch section and cannot be less than 5 meters.
The end of a pipe for escaping part the most fragile, how to protect the entrance termination of pipe for escaping becomes means of escape
The main task of protection.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, there is provided a kind of structure is novel, can reflect
The explosion-proof pipe for escaping end protective cover of rotor of stone.
The technical scheme adopted by the utility model is that：
A kind of explosion-proof pipe for escaping end protective cover of rotor, includes the hollow cone protection of integrally formed round and smooth arc-shaped head
Cover, installs flashing light in the tapered middle inside of protective cover, four is installed uniformly at intervals in the cone lateral wall of flashing light opposite side
A knob, pastes dustcloth in cone lateral wall surrounding, is fixedly mounted with four fixations in the cone inside edge of flashing light side and grabs,
Four fixations grab middle part and are formed with and are bent in an arc shape arc.
Moreover, axial fin is formed with arc is grabbed.
Moreover, phosphor strip is fixedly mounted with knob.
The advantages of the utility model and good effect are：
Explosion-proof pipe for escaping end protective cover of rotor provided by the utility model is integrated the hollow cone for making circular arc head
Protective cover, can reflect away how escape pipe end stone, fully ensure that pipe safety, can be by fragile pipe for escaping
Edge, effectively prevents pipeline breaking caused by the surprise attack of rubble, and means of escape is safer, ensures life channel.
Explosion-proof pipe for escaping end protective cover of rotor provided by the utility model has multiple handles, and phosphor strip is installed on handle
Band, can identify handling position moment, improve escape efficiency.
The edge of explosion-proof pipe for escaping end protective cover of rotor provided by the utility model is fixedly mounted with dustcloth, on the one hand can protect
The edge of protective cover is demonstrate,proved, on the other hand can protect impact of the stone from opposite direction to protective cover and pipeline, it is safer.
Brief description of the drawings
Fig. 1 is the structure diagram of stent.
Fig. 2 is the sectional view along A-A of Fig. 1.
Fig. 3 is the structure diagram of knob.
Embodiment
With reference to embodiment, following embodiments, which are illustrative, are not limited is further illustrated to the utility model
, it is impossible to limit the scope of protection of the utility model with following embodiments.
A kind of explosion-proof pipe for escaping end protective cover of rotor, includes the hollow cone protection of integrally formed round and smooth arc-shaped head
Cover 2, installs flashing light 3 in the tapered middle inside of protective cover, is installed uniformly at intervals in the cone lateral wall of flashing light opposite side
Four knobs, paste dustcloth 1 in cone lateral wall surrounding, are fixedly mounted with four fixations in the cone inside edge of flashing light side and grab
4, it is formed with the middle part of four fixations are grabbed and is bent in an arc shape arc 6, the sealing ring for being embedded in pipe for escaping extends out arc.
In order to further enhance the fixed intensity grabbed, axial fin is formed with arc is grabbed.
Knob is seen in order to moment, and phosphor strip 7 is fixedly mounted with knob.Explosion-proof pipe for escaping provided by the utility model
End protective cover of rotor has multiple handles, and fluorescent bands are installed on handle, can identify handling position moment, improves escape efficiency.
Four fixations in the application grab and can be inlaid in the sealing ring of embedded pipe for escaping when mounted and extend out on arc, by
In being all arcuate structure, it is very easy to remove, improves escape efficiency.
