Description
Technical field
The present invention relates to the cable bearer field, particularly relate to a kind of high-temperature cable support and installation method thereof that is used for the diesel exhaust gas collector.
Background technique
The exhaust header high-temperature cable support of low-speed diesel engine is mainly used on the exhaust header of large-scale diesel engine top.Exhaust header has the high characteristics of the big temperature of shake.Main effect is to the shake of diesel engine cable to be carried out the mechanical property protection, prevents the damage of cable machinery property, simultaneously worst hot case is isolated, and prevents that the cable protective layer is aging, thereby causes short circuit between heart yearn.
Because former design exhaust header high-temperature cable support is installed in exhaust header fuel oil side; Because various pipings are numerous here; Be easy to generate the interference of exhaust header high-temperature cable support and piping; All kinds of pipings have limited the setting height(from bottom) of exhaust header high-temperature cable support again, make the cable can not stow away from heat.Former design is usually proposed to reprocess requirement by shipyard behind diesel car.
Through production practices, the following problem that existing technology exists:
The shake of the one, support is severe, and when the diesel engine high load running, because means of fixation is unreasonable, the support shake is severe.Though support has been carried out the reinforcement measure of all directions, but has not reached the acceptance requirement of shipyard.
The 2nd, is because the piping of fuel oil side is suppressed, and the cable bearer design height is restricted, and can't satisfy the requirement of cable stow away from heat.Query when often receiving the shipyard examination is often mentioned cable and is scorched by high temperature easily in reprocessing report, require the cable stow away from heat.
The 3rd. former design support is at the mounting type of fuel oil side, because the compacting of all kinds of pipings, installing space is narrow and small, causes the workshop difficult installation, and the workshop is installed lack of standardization, and support is because the piping compacting can not be unified design form.Cause serial problems such as workshop site operation difficulty.
For this reason, we are necessary the cable bearer structure and the mounting point of exhaust header are designed again.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existing technology; A kind of high-temperature cable support and installation method thereof that is used for the diesel exhaust gas collector is provided; Prevent shake through the rack arrangement position being adjusted, being reached, prevent high temperature; Satisfy requirement, the purpose that makes things convenient for site operation to install to cable protection.
Technical solution of the present invention is following:

Fig. 7 is that the present invention is used for the high-temperature cable support of diesel exhaust gas collector and the schematic representation that is connected of exhaust header, and Fig. 8 the present invention is used for the high-temperature cable support embodiment schematic representation of diesel exhaust gas collector.As shown in the figure, be used for the installation method of the high-temperature cable support of diesel exhaust gas collector, comprise the following steps:
1. on the body of diesel exhaust gas collector, lean on diesel exhaust gas a side radially screw is passed described bending support and described straight bending support is arranged in order; The straight plate or the extension plate of the T steel plate of described high-temperature cable support directly are welded on the body of diesel exhaust gas collector, and the straight plate of this T steel plate or extension plate length are higher than outside the high temperature separation layer of described exhaust header;
2. lay asbestos slate at described bending support and described straight bending rack surface;
3. the high-temperature cable with described diesel exhaust gas collector is securely fixed on the described asbestos slate.
Through integral solder after employing bending support and the straight bending support production, guaranteeing under the firm prerequisite of support overall appearance that can effectively reduce the manufacture process requirement (removing the postwelding manufacturing procedure) to support, minimizing manufacturing process promptly reduces production costs.Ensure yield rate.Lay asbestos slate earlier at rack surface, cabling on asbestos slate utilizes asbestos to completely cut off the excellent specific property of thermal source so again, simultaneously support is installed in outside the exhaust header high temperature separation layer, can carry out high temperature protection to cable from two aspects.Actual measurement makes the cable surface mean temperature that is protected between 55 ℃-65 ℃ under main frame 100% load, significantly reduces than the preceding 85 ℃ of degree of design.
Contrast former design and existing design can significantly be found, the rack arrangement position moves by side to the reverse side exhaust side of exhaust header from the fuel oil of exhaust header, has avoided the thermal source of each cylinder relief opening.And away from the body thermal source of exhaust header (it is outer that support has been contained in exhaust header high temperature separation layer), contoured cradle is more attractive in appearance than former design, and the fastness of support promotes significantly, has eliminated the support shake that diesel engine 100% load causes down.Support installs and fixes pattern to be solidified more and simplifies than former design, and on-the-spot the installation as long as adopt simple Wrench just can accomplish solidified dismounting process.As long as the exhaust header diameter according to different type of machines is different, revise the circular support diameter in proportion.Fine setting is welded on the dull and stereotyped quantity with waist-shaped hole between two pipes, just can satisfy the low-speed diesel engine of different cylinder diameters and produce needs.
The present invention is when the raising support is prevented trembling heat insulation performance; Beautify the outward appearance of homemade diesel engine, and on production technology, optimized, solidified mounting process; Different type of machines all can adopt with a installation dispatch, has advanced homemade diesel engine standardization seriation design work.Under the precondition that reduces production costs, take into account performance, searched out the equinoctial point of design performance and cost, saved installation work-hour, improved the quality that the machine outward appearance has promoted machine, have advantages such as installation is convenient.
