A kind of and bolted tube bank support and restrain assembly methodTechnical field
The present invention relates to the bundling technique field of pipeline, especially relate to fixed support and the method for the tube bank of tying up pipeline, relate to one and bolted tube bank support more specifically and restrain assembly method.
Background technique
In automobile, the layout of air brake piping and electrical equipment wiring harness is tied up one and is directly subordinate to the technical barrier needing in body frame structure for automotive design to solve, layout in vehicle frame of prior art medium and heavy truck inside brake pipeline and electrical equipment wiring harness and fixation method have varied, but all be unable to do without the use of tube bank, therefore the fixation problem of pipeline and wire harness just becomes the fixation problem of tube bank, traditional tube bank fixed solution has two kinds: a kind of is tie up pipeline with nylon cable tie and fix nylon cable tie by the hole on vehicle frame, one is on vehicle frame, install panel beating support, again tube bank is fixed on panel beating support.These two kinds of conventional methods all also exist certain narrow limitation, for the method for being fixed nylon cable tie by the hole on vehicle frame, the serious layout being limited to hole, especially for just carrying out the fixing of nylon cable tie in vehicle frame when atresia, even if its constant intensity porose is also lower, usage requirement can not be met; For the method by panel beating support Fixed Tube-sheet Reboiler, due to panel beating support will be designed, the design of the whole vehicle frame of impact that can be serious, and can cost be increased, also there is the problems such as assembling comparatively bothers in panel beating support simultaneously.Also have above-mentioned two kinds of tube bank fixed solution ubiquities cannot solve contact friction problem on tube bank and vehicle frame between bolt, make tube bank easily receive damage, and then reduce its working life and Safety performance is tied up to pipeline.
Summary of the invention
The present invention is based on above-mentioned prior art problem, the proposition one of innovation is with bolted tube bank support and restrain assembly method, described tube bank support adopts nuts as body, the existing bolt on vehicle frame can be utilized easily to install, simplify tube bank fixed structure and reduce fixed cost, described tube bank support ensures to install join strength by back-off part, the arbitrarily angled requirement of arranging trend of tube bank is met by arranging multiple guiding perforation, tube bank to be fixed and bolt have been carried out effective isolation by tube bank support of the present invention simultaneously, while playing fixation to tube bank, available protecting tube bank is from the wearing and tearing of bolt.Tube bank support provided by the invention can be good at being applicable to the layout of heavy automobile air brake pipeline and electrical equipment wiring harness and fixing, both the fixation problem of tube bank had been solved, turn avoid the problem that tube bank rubs with bolt on vehicle frame, save assembly cost with the structure simplified simultaneously, there is wide marketing prospect of the application.
