Description

A kind of still door gripping unit of environment-friendly rubber cracking still

Technical field

The utility model relates to a kind of gripping unit, especially a kind of still door gripping unit of environment-friendly rubber cracking still.

Background technology

Frequent unlatching rubber cracking still door filling raw material is the indispensable step link of production process in the production process of rubber cracking, unlatching and closure at the still door all is with standing bolt or chain connecting bolt still door and kettle to be fixed and compressed at present, and there are many problems in this kind mode in actually operating.1, the take-down time long, influence production efficiency, every bolts nut all will separate in dismounting, every every still of machine approximately needed about half an hour, had just directly influenced time production cycle of every stove, had also reduced production efficiency certainly.2, labor intensity of operating staff is big, because of the rubber cracking still is that big-and-middle-sized equipment (diameter is more than two meters) event push bolt nut diameter is in 24 millimeter, so the outfit spanner also weighs again with regard to greatly inevitable and quality in dismounting.3, bolt and nut is short work-ing life, is not only because of the demounting bolt nut and unscrews, and will twist separation to nut, just can open the still door, so the nut wearing-in period is long relatively, life cycle is short, needs the take-down time long.4, part is lost easily, after the operator generally dismantles in the dismounting, and general placement conveniently.5, easily cause entanglement in the dismounting, aggravation damages, every bolts nut is unscrewed the degree varies sample, damage intensity is also different, in loading and unloading, intersect repeatedly and use, produce degree of tightness and differ, will aggravate damage intensity, therefore need a kind of gripping unit that can conveniently open with closed still door, to improve above-mentioned defective.

The utility model content

The utility model provides a kind of still door gripping unit of environment-friendly rubber cracking still at the problem that runs in existing rubber cracking still still door unlatching and the closure, and its concrete scheme is as follows:

Comprise kettle, described kettle is located on the base, and kettle one end is provided with kettle cover, uses bolted splice between this kettle and the kettle cover, and described kettle is provided with frame near an end of kettle cover, and described frame is provided with band dead point self-locking clamp mechanism.

Preferably, this band dead point self-locking clamp mechanism comprises that described kettle is near kettle cover position hinged respectively rocking bar and tightening latch;

Between described rocking bar and described tightening latch, also be hinged with connecting rod;

Preferably, an end of tightening latch sensing kettle cover also is provided with the set screw pressure head.

Preferably, the set screw pressure head is the screw that passes tightening latch.

Preferably, screw screws out end and also is provided with nut.

Preferably, the screw threads inlet side also is provided with packing ring.

Preferably, described band dead point self-locking clamp mechanism has a plurality of.

Use the technical solution of the utility model,, it is advantageous that to have substituted bolt or chain connecting bolt in the past:

1, only needs to promote rocking bar and can realize the unlatching of still door, reduce the still door and open required time, improved production efficiency;

2, utilize lever principle to open the still door, reduced labor intensity of operating staff;

3, band dead point self-locking clamp mechanism self wearing-in period is short, and work-ing life is longer relatively;

Need not when 4, opening the still door management is convenient in the dismounting of band dead point self-locking clamp mechanism;

5, there is not the phenomenon that the component intersection is used in bolt or the chain connecting bolt.

Embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.

As shown in Figures 1 to 3, length is that 8000mm, bottom surface diameter are the jar shape rubber cracking still of 3000mm, its kettle 1 level is located on the base 2, and the end at kettle 1 is provided with the opening that is used for input and output material, opening is provided with the kettle cover 3 with the opening shape coupling, therefrom mind-set edge attenuation gradually of kettle cover, kettle cover diameter 3000mm, center thickness 400mm, and kettle cover 3 is hinged by the kettle cover bolt with kettle 1 opening, makes kettle cover 3 closure or openness as required; In kettle 1 periphery near kettle cover 3 positions, the fastening circular frame 4 that is provided with, this frame cross section is a right-angled trapezium, and frame cross section upper base and kettle 1 are conflicted, and the oblique waist of frame cross section is located at by kettle cover 3 one sides; And on the oblique waist of frame 4, be hinged with rocking bar 5; Equally on frame 4 oblique waists, more depart from a side of kettle 1 than rocking bar 5 pin joints, also be hinged with tightening latch 6; Mid point at rocking bar 5 and tightening latch 6 is respectively equipped with pin joint, is hinged with a connecting rod 7 between two pin joints.

In the foregoing description scheme, frame 4 cross section inclined-planes, rocking bar 5, tightening latch 6 and connecting rod 7, the common four-bar mechanism of forming a band dead-centre position, with rocking bar 5 is driving lever, tightening latch 6 is a follower lever, when needs carry out closure to kettle cover 3, close kettle cover 3 earlier, promote rocking bar 5 and make rocking bar 5 and connecting rod 7 conllinear, this moment, four-bar mechanism was in the dead-centre position, and the movable end of tightening latch 6 and kettle cover 3 are conflicted, thereby realize the clamped closed to kettle cover 3, when needing to open kettle cover 3, oppositely promote rocking bar 5, can make four-bar mechanism break away from the dead-centre position, tightening latch 6 breaks away from from kettle cover 3 conflicts, and realizes kettle cover 3 unlatchings.

As the improvement of the foregoing description technical scheme, be to improve the closed degree of shape of tightening latch 6 and kettle cover 3, also be provided with screw at the movable end of tightening latch, and screw passed screw screw 8 and kettle cover are conflicted.

Embodiment technical scheme after the above-mentioned improvement can be by adjusting the clamping degree that the precession degree of screw 8 on tightening latch come set screw and kettle cover.

As the improvement of the foregoing description technical scheme, screw 8 screws out on the end and also is provided with nut.

As the improvement of the foregoing description technical scheme, also be provided with packing ring on the screw 8 precession ends.

As the improvement of the foregoing description technical scheme, described band dead point self-locking clamp mechanism has a plurality of, is distributed in the kettle open circumferential.

More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
