In a kind of concrete execution mode, described sliding connector comprises hook and slide block.
In the present invention, the length of described guard shield C, guard shield B and guard shield A is corresponding or longer to the length of forearm, rear telescopic arm and front stretching arm respectively, makes the slip between guard shield C and guard shield B and between guard shield B and guard shield A smoothly and can not depart from.
In the present invention, the rear end of described guard shield and front end refer to rear 1/2 part in guard length direction and front 1/2 part, in rear 1/3 part that preferred support A, support B, support C and support D are all arranged on guard length direction and front 1/3 part.
In a kind of concrete execution mode, described guard shield C, guard shield B and guard shield A are in the height direction in setting gradually up and down.Line protecting apparatus compact overall structure while set-up mode like this makes pipeline can obtain adequately protecting, convenient and practical.
Line protecting apparatus, the width of described guard shield is the diameter sum being greater than two pipelines, and can accommodating more than two pipelines arranged in parallel in guard shield.In a kind of concrete execution mode, pipeline (flexible pipe of such as conveying liquid force feed and control cable) is all arranged on and comprises in the same group of guard shield of guard shield C, guard shield B and guard shield A.
In a kind of concrete execution mode, in described device, also comprise the pipe clamp be fixed in a place of pipeline or many places in guard shield.Correct position in guard shield arranges marshalling between pipeline that pipe clamp can make in guard shield, the characteristics of motion.
In a kind of concrete execution mode, described guard shield be strip axially in both ends open and radial section be hat by the guard shield of steel plate bending.
In a kind of concrete execution mode, described pipeline comprises the soft pipeline that at least two sections can be done bending campaign, and in pipeline, remainder is hard tube line and/or soft pipeline.Pipeline integrity of the prior art needs to do bending campaign as shown in Figure 1, and thus pipeline is wherein all soft pipeline.And the part paragraph in pipeline of the present invention is fixedly installed in guard shield, thus these paragraphs can be soft pipeline or hard tube line.As shown in Figure 3, the bending pipeline between the pipe clamp 14 of two fixed pipelines is soft pipeline.Flexible pipe line segment in the present invention is all arranged in guard shield, can not bear the destruction from adverse circumstances in tunnel in work progress, and it can adapt to the high frequency bending campaign of flexible pipe in work progress well.
The present invention also provides a kind of boom system, comprises line protecting apparatus described above and comprises the jib of forearm, rear telescopic arm and front stretching arm.
The present invention is also corresponding provides a kind of concrete spraying vehicle, comprises boom system as above.
The present invention at least has following beneficial effect:
1) pipeline such as hydraulic tube is fixed in guard shield by pipe clamp, and the pipeline of length in reserve is also all arranged in guard shield.When wet-spraying machine operation, no longer there is situation about arbitrarily swinging in pipeline; And pipeline can not be hung with miscellaneous part and mixes, pipeline is caused to damage or the situation of other damage of components.Thus can available protecting pipeline, effectively extend its useful 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 the unlikely distortion under pipeline and guard shield Gravitative Loads of flexible pipe guard shield; Solve the high and yielding problem of flexible pipe guard shield frequency of utilization.
