Description

Remove saw cutting device and the sawing method of header pipe joint water pressure end cap
Technical field:
The present invention relates to a kind of saw cutting device removing header pipe joint water pressure end cap and sawing method.
Background technology:
Owing to boiler header needs to carry out the water pressure test in maker, pipe joint thereon needs welding water pressure end cap to seal, and needs to remove the water pressure end cap on pipe joint after the water pressure test.
The method removing pipe joint water pressure end cap commonly used at present is that manual oxygen cutting is removed one by one, manual oxygen cutting efficiency is low, and labor intensity is big, is unfavorable for producing in enormous quantities, and the pipe joint for P91 class cannot be made directly gas cutting, in addition it is also necessary to increasingly complex method removes water pressure end cap.And the unevenness of pipe joint end face is big after manual oxygen cutting, when pipe joint groove processed by follow-up use drilling machine, cutter of drill machine and drilling machine lathe bed are damaged bigger.
Summary of the invention:
It is an object of the invention to provide a kind of saw cutting device removing header pipe joint water pressure end cap and sawing method.
Above-mentioned purpose is realized by following technical scheme:
A kind of saw cutting device removing header pipe joint water pressure end cap, its composition includes: moveable carriage, described moveable carriage is provided with pedal, described pedal is connected with hydraulic stem, described hydraulic stem is connected with chain, one end of described chain is welded on described moveable carriage, the other end of described chain is welded on hoistable platform, one end of described hoistable platform is provided with rubber wheel, described rubber wheel is arranged in the vertical channel-section steel of described moveable carriage, drive motor is arranged on described hoistable platform, Toothless saw blade is bolted on the main shaft of described drive motor.
A kind of sawing method of the saw cutting device removing header pipe joint water pressure end cap, operationally, the pipe joint horizontal positioned of sawing will be needed, promote moveable carriage near pipe joint, adjusted the height of hoistable platform by pedal on dolly, when Toothless saw blade upper end and pipe joint close to time open drive motor, slowly raised the height of hoistable platform by the pedal of liftable dolly bottom simultaneously, pipe joint is carried out sawing by the Toothless saw blade utilizing high speed rotating, a multiple pipe joint of sawing.
Beneficial effect:
1. the present invention adopts Toothless saw blade that pipe joint is carried out sawing, once can many pipe joints of sawing, work efficiency is high, and after sawing, pipe socket end is smooth, is beneficial to the carrying out of subsequent handling.
2. the invention solves P91 class pipe joint and can not be removed the difficult point of hydraulic pressure surplus by gas cutting mode, directly P91 class pipe joint can be carried out sawing to remove water pressure end cap, the method avoiding complexity, it is possible to remove the water pressure end cap of P91 class pipe joint simply and effectively.
3. pipe joint efficient, high-quality can be carried out sawing by the present invention, and after using the sawing of this device, work efficiency is greatly improved, and pipe joint end face is smooth simultaneously, damage when greatly reducing finished edge, cutter of drill machine and drilling machine lathe bed caused.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the structural representation of the elevating mechanism of the present invention.
Detailed description of the invention:
Embodiment 1:
A kind of saw cutting device removing header pipe joint water pressure end cap, its composition includes: moveable carriage 1, described moveable carriage is provided with pedal 2, described pedal is connected with hydraulic stem 3, described hydraulic stem is connected with chain 4, one end of described chain is welded on described moveable carriage, the other end of described chain is welded on hoistable platform 5, one end of described hoistable platform is provided with rubber wheel 6, described rubber wheel is arranged in the vertical channel-section steel of described moveable carriage, drive motor 7 is arranged on described hoistable platform, Toothless saw blade 8 is bolted on the main shaft of described drive motor.
Embodiment 2:
The sawing method of the above-mentioned saw cutting device removing header pipe joint water pressure end cap, operationally, the pipe joint horizontal positioned of sawing will be needed, promote moveable carriage near pipe joint, adjusted the height of hoistable platform by pedal on dolly, when Toothless saw blade upper end and pipe joint close to time open drive motor, slowly raised the height of hoistable platform by the pedal of liftable dolly bottom simultaneously, pipe joint is carried out sawing by the Toothless saw blade utilizing high speed rotating, a multiple pipe joint of sawing.
Embodiment 3:
The described saw cutting device removing header pipe joint water pressure end cap, equipped with universal wheel bottom described moveable carriage, can promote to any direction, described lifting platform is arranged on moveable carriage by actuating device, and by the pedal Artificial Control lifting bottom dolly, described Toothless saw blade is arranged on the main shaft of drive motor, rotarily drives Toothless saw blade high speed rotating by drive motor main shaft, to carry out sawing.
