Abstract
Disclosed is a saw cutting device and method for removing a water pressure end cover of a header pipe joint. The existing water pressure end covers of pipe joints are removed one by one in a manual gas cutting mode by the general method which is low in manual gas cutting efficiency, large in labor intensity and not beneficial to mass production. The saw cutting device comprises a mobile trolley (1) which is provided with a pedal plate (2); the pedal plate is connected with a hydraulic rod (3) which is connected with a chain (4); one end of the chain is welded on the mobile trolley and the other end of the chain is welded on a lifting platform (5); one end of the lifting platform is provided with a rubber wheel (6) which is arranged in vertical channel steel of the mobile trolley; a driving motor (7) is arranged on the lifting platform; a toothless saw blade (6) is connected onto a main shaft of the driving motor through a bolt. The saw cutting device and method is used for removing the water pressure end cover of the pipe joint.
Description
technical field:
the present invention relates to a kind of saw cutting device and sawing method of removing header pipe joint hydraulic pressure end cap.
background technology:
because boiler header need to carry out the water pressure test in manufactory, the pipe joint on it need to weld hydraulic pressure end cap and seal, and needs to remove the hydraulic pressure end cap on pipe joint after the water pressure test.
the method that removal pipe joint hydraulic pressure end cap generally adopts is at present that manual oxygen cutting is removed one by one, manual oxygen cutting efficiency is low, and labour intensity is large, is unfavorable for producing in enormous quantities, and the pipe joint for P91 class cannot directly carry out gas cutting, also need more complicated method to remove hydraulic pressure end cap.And the unevenness of pipe joint end face is large after manual oxygen cutting, larger to cutter of drill machine and the damage of drilling machine lathe bed when follow-up use drilling machine processing tube joint bevel.
summary of the invention:
the object of this invention is to provide a kind of saw cutting device and sawing method of removing header pipe joint hydraulic pressure end cap.
above-mentioned object realizes by following technical scheme:
a kind of saw cutting device of removing header pipe joint hydraulic pressure end cap, its composition comprises: moveable carriage, on described moveable carriage, pedal is installed, 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 motors is arranged on described hoistable platform, Toothless saw blade is bolted on the main shaft of described drive motors.
a kind of sawing method of removing the saw cutting device of header pipe joint hydraulic pressure end cap, when work, the pipe joint horizontal positioned of sawing will be needed, promote moveable carriage near pipe joint, pedal by dolly is adjusted the height of hoistable platform, when the upper end of Toothless saw blade and pipe joint approach, opens drive motors, slowly raises the height of hoistable platform by the pedal of liftable dolly bottom simultaneously, utilize the Toothless saw blade of High Rotation Speed to carry out sawing to pipe joint, a plurality of pipe joints of sawing.
beneficial effect:
1. the present invention adopts Toothless saw blade to carry out sawing to pipe joint, once can many pipe joints of sawing, and operating efficiency is high, and after sawing, pipe joint end is smooth, is beneficial to the carrying out of subsequent handling.
2. the invention solves P91 class pipe joint and can not remove by gas cutting mode the difficult point of hydraulic pressure surplus, can directly to P91 class pipe joint, carry out sawing to remove hydraulic pressure end cap, avoid complicated method, can remove simply and effectively the hydraulic pressure end cap of P91 class pipe joint.
3. the present invention can efficient, high-qualityly carry out sawing to pipe joint, uses after the sawing of this device, and operating efficiency is greatly improved, and simultaneously pipe joint end face is smooth, the damage while greatly having reduced finished edge, cutter of drill machine and drilling machine lathe bed having been caused.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is structural representations of elevating mechanism of the present invention.
