More than the diameter of steel wire rope, the second rectangular channel is setting one and the second rectangular channel phase on upper shear knife length direction
The logical cavity in concave；The length and width of second rectangular channel and the length and width of hinge match, and one end of steel wire rope is fixedly connected
On hinge, the termination of the other end of steel wire rope is in annular shape, and locking post with the locking integrally formed crotch of post by hanging over steel
On the termination in annular shape of cord, locking post is made up of metal material, and the diameter for engaging the cylinder of post is more than the first rectangular channel
Width, the height in the middle part of the height and hinge of the center section of cavity matches, and the entire length and height of cavity is allow
The size that hinge is flipped up, upper shear knife by several bolts be tightened in it is upper shearing tool rest on, the middle part of cavity just under
Side shears the side screwed hole of tool rest to be arranged on, and the side screwed hole is small close to the side of upper shearing tool rest, the width of hinge
In the aperture of side screwed hole；The lower section fixed setting nut of the hinge puts mechanism, and the nut, which puts mechanism, includes one
Bottom surface is provided with the cylindrical connecting plate being fixed on below hinge of cylindrical blind hole, the hole of the cylindrical blind hole
Be installed with stopper on wall, on the lateral wall of the nut matching be provided with and stopper corresponding to prodger, the prodger
One end is hinged on nut, and the other end of prodger is connected in the groove set on nut lateral wall by spring, is being connected
The circumference of the cylindrical blind hole of the bottom of plate is nearby additionally provided with the ring baffle for preventing nut from dropping, the ring baffle with
Connecting plate is integrally formed, and the external diameter of the cylindrical connecting plate is less than the aperture of side screwed hole；It is arranged on shear knife
Screwed hole below the screwed hole of side is shaped as the large cylindrical hole narrowing toward each end cylindrical hole in middle part, the large cylindrical hole
Aperture is more than the length of hinge, and the inwall in large cylindrical hole does not set internal thread, and the inwall of roundlet cylindrical hole is provided with and bolt outer wall
The internal thread of external screw thread matching.So simply slightly changed on the upper shearing tool rest of original gate shears and upper shear knife, i.e.,
Rapid-assembling/disassembling knife is realized, specific operating procedure is as follows：Hinge is first put into the second rectangular channel before dress knife（Due to the second rectangle
The size of groove matches with the size of hinge, therefore hinge is being put into rear position very just）In, while the steel wire rope being connected with hinge is put into
First rectangular channel（At this moment steel wire rope does not hang tag also only post in circular termination, and in order to ensure hinge being put into the
Exposing in circular termination for steel wire rope is longer than the first square in the side of upper shearing tool rest, the length of steel wire rope after two rectangular channels
The length of shape groove is added at the top of the screwed hole of side to the distance at the top of large cylindrical hole plus the length of the second rectangular channel）, then
The hinge inserted in the second rectangular channel is dialed in cavity by instruments such as shift forks, locking post is at this moment hung over into steel wire again
On the termination in annular shape of rope（To prevent the preponderance for engaging post that the hinge for having inserted cavity is pulled into the second rectangular channel,
At the close upper shearing tool rest side of the first rectangular channel an elastic clip can be set to clamp steel wire rope, certainly, if locking post
Material selection properly i.e. weight is not heavy to pull out hinge without this setting）, afterwards as former dress knife,
All bolts, which are tightened, will go up shearing tool rest and upper shear knife acts conjunctively to complete dress knife.
As the further improvement of the convenient assembly and disassembly knife system of gate shears of the present invention, two spiral shells close to upper shearing tool rest side

It is screwed into nut, is arranged on plus nut in circular blind hole；Nut is inverted with bolt when tearing knife open, and prodger when inverting
Due to the presence of stopper the elastic force of spring can be overcome to collapse into groove, so during bolt continues to turn, bolt
Moved downward because the screw thread with side screwed hole coordinates, and nut can only then rotate in circular blind hole, and due to spiral shell
Bolt moves downward, and hinge overcomes the torsion of torsion spring to pack up into side screwed hole with the decline of bolt to decline, until hinge
Drop down onto in large cylindrical hole, the torsion spring of hinge discharges elastic force and flare up original state without resistance（Tabular）, at this moment continue according to
Sequence unscrews whole bolts up to the bolt most on side to another side, and the bolt on both sides, will not be due to whole due to identical setting
Unscrewing for bolt and blade needs people to hold（Because now upper shearing tool rest and upper shear knife pass through hinge, steel wire rope and locking
Post is connected to, and locking post is not taken down from steel wire rope the size therefore steel that can be more than the first rectangular channel due to engaging the size of post
Cord is tight, and upper shearing tool rest and upper shear knife are ined succession by steel wire rope, are held without people）As long as at this moment take away and hang over steel
Locking post in cord can be achieved outwards to send out the reserved tool changing notch that upper shear-blade is provided with by frame both sides, more
Preferable scheme is that the length of steel wire rope is longer again, and upper shear knife is suspended in that by steel wire rope after so unscrewing whole bolts,
Operative employee by one end be raised to reserved tool changing notch by blade move to reserved tool changing notch take away again two locking posts i.e. can be achieved
Tear knife open.Also whole bolts dare not be unscrewed rapidly with needing people to hold in the past（Worry that all unscrew blade drops quickly）Tear open
Knife process is compared, and speed improves quite a lot of, and fills knife and tears knife step open almost and as before, only when filling knife and tearing knife open more than
One step.And upper shear knife loses constraint after the locking post in circular termination for hanging over steel wire rope is taken away, bolt,
Hinge and the steel wire rope upper shearing tool rest as upper shear knife leaves, again pull downward on bolt after pulling down shear knife, hinge is then
Overcome elastic force to pack up, continue to pull down bolt, hinge and the steel wire rope that bolt is realized in the blade that will be pulled down and be pulled away from and shear
Knife, bolt, hinge and the steel wire rope of pull-out are by further processing（It is specially artificial to pin nut on the other hand, continue on the other hand according to
Tearing the direction rotating bolt to be loosered a bolt during knife open before realizes the separation of bolt and hinge, follow-up can be fixedly connected again
