Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1 to Fig. 2.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
Consult shown in Fig. 1, bilateral scissors hold down gag comprises a clamp sleeve 3, is equipped with a buffering bolt 2 in clamp sleeve 3.The rear end of buffering bolt 2 is fixedly connected with by the tail end of locking nut 5 with clamp sleeve 3, and the front end of buffering bolt 2 is stretched out from the head end of clamp sleeve 3, and buffering bolt 2 is arranged with one group of butterfly spring sheet.The tail end of clamp sleeve 3 is provided with two otic placodes, 10, two otic placodes 10 be parallel to each other and is provided with concentric connecting hole.When changing the butterfly spring sheet on the buffering bolt 2 of dismounting clamp sleeve 3 inside, the locking nut 5 that its rear end and clamp sleeve tail end are fixed must be dismantled.Therefore, the elastic force effect how solving spring on absent-mindedness buffering bolt is after stopping to lay down locking nut, and buffering bolt ejects instantaneously, causes the key factor that the accidental mechanical injury accident of maintainer occurs.
Based on above object, consult shown in Fig. 2, be shown as the structural representation of the dismounting frock of the utility model bilateral scissors hold down gag, dismounting frock comprises a pilot sleeve 4, the two ends of pilot sleeve 4 connect a front support stand and a rear support stand respectively, form approximate " H " type, the middle part of H is the pilot sleeve 4 of tubulose, is used for entangling clamp sleeve 3 and plays guide effect.Front support stand comprises the baffle plate 7 that is oppositely arranged on pilot sleeve front, baffle plate 7 is equipped with one for propping up the adjusting bolt 1 of buffering bolt front end.Rear support stand comprises two fixed head 9, two fixed heads 9 parallel with pilot sleeve 4 and is provided with two concentric fixing holes, wears a fixed bar 6 in two fixing holes.
Assembly and disassembly methods below in conjunction with the dismounting frock of bilateral scissors hold down gag is described in further detail, and dismounting step is as follows:
1) pilot sleeve 4 is sheathed on clamp sleeve 3.
2) use fixed bar 6 simultaneously through two connecting holes and two fixing holes.
3) adjusting bolt 1 is rotated, until adjusting bolt 1 advances to the front end propping up buffering bolt 2, thus the butterfly spring sheet on clamp sleeve internal damping bolt is compressed further, and then the locking nut 5 that buffering bolt rear end is connected with clamp sleeve is in free state, and there is certain interval with clamp sleeve 3.
4) if locking nut 5 can unclamp, directly unclamp and disassemble, if become rusty dead or be welded on buffering bolt in order to locking, then use cutting tool to cut off locking nut 5.Because the elastic force of butterfly spring sheet is withstood in the clamping torque reaction of adjusting bolt 1 to buffering bolt 2.Ensure that locking nut 5 is laid down moment and can not be ejected injury maintainer, eliminate accidental mechanical injury accident and occur, ensure that normally carrying out of upkeep operation.
5) dismantle after locking nut 5, unclamp adjusting bolt 1, the elastic force of absent-mindedness butterfly spring sheet, dismounting fixed bar 6, takes out buffering bolt 2, changes one group of new butterfly spring sheet;
6) put into new buffering bolt 2 in clamp sleeve 3, fixed bar 6 through two connecting holes and two fixing holes, tightens adjusting bolt 1, holddown spring elastic force simultaneously, installs and tightens locking nut 5, and use the firm locking nut of electric welding, installation.
As further improvement of the utility model, front support stand comprises between two gripper shoe 8, two gripper shoes 8 parallel with pilot sleeve and arranges baffle plate 7.Baffle plate 7 is provided with the screwed hole of one and clamp sleeve axle center conllinear, wears adjusting bolt 1, thus play better guide effect in screwed hole, when preventing from rotating adjusting bolt 1, and bolt sideslip, displacement.
6 people *, 8 hours/day replacing hold down gag buffering bolts are needed before improvement.2 people and replaceable hold down gag buffering bolt is only needed after improving.Save labour: 4 people * 300 yuan/time=1200 yuan.
In sum, the utility model solves a difficult problem for loaded down with trivial details maintenance hold down gag buffering bolt, stopped that unexpected personal injury occurs hidden danger, reduce the labour intensity of maintainer, improve overhaul efficiency.So the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
