In a kind of specific embodiment, described device also includes the pipe clamp being fixed in guard shield by a place or the many places of pipeline.Correct position in guard shield arranges pipe clamp can make marshalling between the pipeline in guard shield, the characteristics of motion.
In a kind of specific embodiment, described guard shield be axially strip in both ends open and radial section be hat by the guard shield of steel plate bending.
In a kind of specific embodiment, described pipeline includes at least two sections of soft pipelines that can do bending campaign, and in pipeline, remainder is hard tube line and/or soft pipeline.Pipeline entirety of the prior art needs to do bending campaign as shown in Figure 1, thus pipeline therein is all soft pipeline.And the part paragraph in this utility model pipeline is fixedly installed in guard shield, thus these paragraphs can be soft pipeline or hard tube line.As it is shown on figure 3, the bending pipeline between the pipe clamp 14 of two fixed pipelines is soft pipeline.Flexible pipe line segment in this utility model is provided entirely in guard shield, and the destruction being not subject in tunnel adverse circumstances in work progress, it can be well adapted for the high frequency bending campaign of flexible pipe in work progress.
This utility model also provides for a kind of boom system, including line protecting apparatus described above and the jib comprising forearm, rear telescopic arm and front stretching arm.
This utility model correspondingly provides a kind of concrete spraying vehicle, including boom system as above.
This utility model at least has the advantages that
1) pipeline such as hydraulic tube is fixed in guard shield by pipe clamp, and the pipeline of length in reserve is also provided entirely in guard shield.When wet-spraying machine operation, no longer there is the situation of arbitrarily swing in pipeline；And pipeline will not hang with miscellaneous part and mix, pipeline is caused to damage or the situation of other damage of components.Thus can effectively protect pipeline, effectively extend its service life.
2) guard shield adopts steel plate bending technique to make, and as shown in Figure 6, this cross sectional shape has good rigidity to its cross sectional shape, makes flexible pipe guard shield will not deform under pipeline and guard shield Gravitative Loads；Solving flexible pipe guard shield uses frequency high and yielding problem.
