Background technology
At present, known drum type flying shears is mainly made up of parts such as flying shear frame, transmission mechanism, rotary drum and synchromesh gear, flying shear blade, blade hydraulic locking mechanism, stub bar and material tail gathering-devices.This cutting mechanism is connected with main gear reducer by gear coupling by an ac synchronous motor, and main gear reducer output is connected with lower rotary drum by crown gear coupling, between upper and lower rotary drum, is connected by synchromesh gear.In the time of motor-driven, drive lower rotary drum to rotate, upper rotary drum also rotates simultaneously, synchronously reaches clipped position by being contained in one group of blade that matches on upper and lower rotary drum, shears head or tail.Blade is arranged in the notch on rotary drum, and each rotary drum has two blades, arranges according to crop or back-end crop interval certain angle.While shearing due to flying shearing machine, can produce very large impulsive force, loosening when avoiding knife cut, the disk spring that blade arranges before by hydraulic cylinder in rotary drum is locked, hydraulic oil by the 16～20MPa pressure from hydraulic trolley promotes the piston rod in hydraulic cylinder, compression disk spring, the briquetting being pressed on blade can be unclamped to more allowing blade replacement.Because drum type flying shears blade abrasion in shearing work is very large, replacement frequency is high, changes online drum type flying shears blade and needs the omnidistance cooperation of rane trolley, and holding time is long, affects other overhauling project and implements, and has hindered the raising of upkeep operation rate.General Production Lines is equipped with two drum type flying shears, and when a breaks down, entirety hangs, and off-line is changed drum type flying shears blade.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, easy to use, the online device of changing drum type flying shears blade, make drum type flying shears not rely on rane trolley and carry out online more allowing blade replacement, increase work efficiency, and rane trolley being without taking for a long time.
The utility model is taked following technical scheme, a kind of device of online replacing drum type flying shears blade, on the framework memorial archway of rotary drum, being fixed with two of four pillars and left and right is one group, above every group of pillar, fixedly mount crossbeam, both sides at crossbeam longitudinally fixedly mount slide rail, form frame structure; Assembly pulley is installed on slide rail, and assembly pulley is connected with bottle gouard moved by hands by U-shaped support.
Described slide rail is that shaped as frame and below are provided with opening formation chute, and assembly pulley is arranged in chute.
Described slide rail is I-beam, and assembly pulley is installed in " work " font groove of I-beam both sides.
Described assembly pulley is arranged on the slide rail in one group of pillar crossbeam outside.
Described one group of pillar is than the high 50mm～100mm of another group pillar.
When the utility model uses, the bottom of four pillars is fixed on the framework memorial archway of rotary drum, can uses.
The beneficial effects of the utility model are, according to shear-blade dismounting position, more changing device is set, can change online drum type flying shears blade, alleviate the use burden of rane trolley in repair schedule, do not need off-line to change drum type flying shears blade and remove miscellaneous part, improve operating efficiency, and simple in structure, easy for operation.

In figure: 1, slide rail, 2, assembly pulley, 3, bottle gouard moved by hands, 4, pillar, 5, crossbeam, 6, suspension ring, 7, blade, 8, retaining mechanism, 9, rotary drum, 10, hydraulic trolley, 11, framework memorial archway, 12, U-shaped support, 13, chain, 14, power transmission shaft.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.Referring to Fig. 1, Fig. 2, a device for online replacing drum type flying shears blade is fixed with four pillars 4 on the framework memorial archway 11 of rotary drum and two of left and right are one group, laterally fixedly mounts crossbeam 5 above every group of pillar 4, both sides at crossbeam 5 longitudinally fixedly mount slide rail 1, form frame structure; Assembly pulley 2 is installed on slide rail 1, and assembly pulley 2 is connected with bottle gouard moved by hands 3 by U-shaped support 12.
Described slide rail 1 is that shaped as frame and below are provided with opening formation chute, and assembly pulley 2 is arranged in chute.
Described slide rail 1 is I-beam, and assembly pulley 2 is installed in " work " font groove of I-beam both sides.
Described assembly pulley 2 is arranged on the slide rail 1 in one group of pillar, 4 crossbeam 5 outsides.
Described one group of pillar 4 is than the high 50mm～100mm of another group pillar 4.
embodiment 1:as shown in Figure 1, its cutting mechanism of existing drum type flying shears is mainly by providing hydraulic locking mechanism 8, hydraulic trolley 10 on the blade 7 installed on the framework memorial archway 11 of lower rotary drum, upper and lower rotary drum 9 and rotary drum 9, blade 7 to form.Upper and lower rotary drum 9 is connected by synchromesh gear; Hydraulic locking mechanism 8 inside are hydraulic cylinder, according to 7～15 of the length operated by rotary motion of blade 7, hydraulic cylinder front portion is provided with disk spring, by the tension-stretched briquetting being pressed on blade 7 of disk spring, hydraulic cylinder rear portion is oil transportation channel, connects by sebific duct in the end of rotary drum 9 with hydraulic trolley 10; Power is provided by the power transmission shaft 14 connecting with motor.As can be seen from Figure 1, four pillars 4 of the present utility model are for the ease of installing, and bottom is welded with steel plate, is provided with screw on it, is fixed by bolts on the framework memorial archway 11 of rotary drum.Four pillars 4 are divided into two groups, and two of left and right are one group, make of channel-section steel, divide the both sides that stand in rotary drum 9, connect or are welded and fixed crossbeam 5 is installed above every group of pillar 4 with bolt, and crossbeam 5 adopts channel-section steel to make.Longitudinally connect with bolt or be welded and fixed on the both sides of crossbeam 5 slide rail 1 is installed, form frame structure.Frame structure is with bolts is to be convenient to dismounting carrying, be welded and fixed certainly more durable, but frame structure weight, carrying is inconvenient, is applicable to not need the occasion of often removing.Slide rail 1 adopts three channel-section steels to be welded into shaped as frame, below two channel-section steel openings be oppositely arranged, leave gap, form chute with channel-section steel welding above, assembly pulley 2 is arranged in chute, the roller on assembly pulley 2 can roll back and forth in chute.As Fig. 2, the axle on assembly pulley 2, through two holes on U-shaped support 12, forms suspension ring.In order to reduce assembly pulley 2 strokes, assembly pulley 2 is preferably disposed on the slide rail 1 in one group of pillar, 4 crossbeam 5 outsides.Stable for lifting operation, preferably slide rail 1 tilts to install, and one group of pillar 4, than the high 50mm～100mm of another group pillar 4, makes assembly pulley 2 lean against crossbeam 5 limit operations.
embodiment 2:as Fig. 3, the slide rail 1 in the utility model can also adopt I-beam, and now assembly pulley 2 adopts female bracket to be installed in " work " font groove of I-beam both sides.Assembly pulley 2 is connected with the hook of bottle gouard moved by hands 3 by U-shaped support 12.Other are identical with embodiment 1.
The utility model in use, the hydraulic fluid pressure compression disk spring that utilizes hydraulic trolley 10 to provide, open drum type flying shears insert retention mechanism 8, make blade 7 in releasing orientation, assembly pulley 2 slides into crossbeam 5 outer fixs, hang up bottle gouard moved by hands 3, hook the suspension ring 6 at blade 7 two ends by bottle gouard moved by hands 3 bottom suspension hooks, pull the chain 13 on bottle gouard moved by hands 3, promote blade 7 and depart from rotary drum 9, outside slide rail 1, drawing assembly pulley 2 to make blade 7 and the distance of rotary drum 9 is 600mm～800mm, puts down, and completes dismantlement work.
