Degree reduces frictional force when rotation, keeps rotation process more smooth laborsaving；Sleeve (4) is used as lever, while internal as accommodating
The shell of part, offers the kidney slot of specific length and width on side wall, attachment screw (11) connect lifting handle (5) and
The kidney slot opened up on sleeve (4) is passed through while T-connecting piece (13), it can be to avoid end lifting handle (5) with end nut (1)
It is same to turn；After removing nut (12), attachment screw (11) are extracted out from sleeve (4), lifting handle (5) and T-connecting piece (13), just
It can overall pulling down component as composed by tension spring (6), hook (7), pin (8) and T-connecting piece (13).To be adapted to various specifications
Locking locking plate (14), the hook (7) of various specific lengths and width can be processed, and be adapted to tension spring (6), pin (8) and T shape connect
Fitting (13), to form multiple components.The replacement of component can be completed by dismounting attachment screw (11) and nut (12), and connect
The side on the head and nut (12) that connect screw (11) is machined with annular knurl, in order to tighten by hand and unscrew；When dismantlement work is complete
Cheng Hou tightens nut (12) after rotation end nut (1) adjustment adjusts screw (11) to appropriate location, can fix a whole set of dedicated
Tool prevents loose.
The utility model technical effect:
The distinguishing feature of the utility model is: the utility model is made for dismantling reactor coolant pump hydraulic part
Locking locking plate, application method is simple and reliable, substantially reduces to the skill requirement of operator；It symmetrically exerts a force when work, it can
It effectively prevent damaging counterbore mounting groove when disassembly locking plate, and to workpiece surface without any damage.Applicability is wide, can be applied to a variety of
The locking locking plate of specification.Structure is simply readily produced and safeguards, good economy performance.
Detailed description of the invention:
Fig. 1 is the schematic diagram of the section structure of specific purpose tool.
Fig. 2 is the A-A the schematic diagram of the section structure of Fig. 1.
Specific embodiment:
As shown in Figure 1, a kind of for dismantling the specific purpose tool of locking locking plate, hook 7 passes through pin 8 and T-connecting piece 13
Hingedly, tension spring 6 is mounted in the circular hole that two hooks, 7 upper end opens up；T-connecting piece 13 passes through attachment screw 11 and lifting handle 5
It is fixedly connected；Lifting handle 5 is threadedly coupled with end nut 1；Spanner 2 is fitted into two circular holes opened up on end nut 1, O-ring 10
It is mounted in the groove of 2 one end of spanner；Backing plate 9 is pasted and fixed on 4 lower end of sleeve；End nut 1 is inserted by the boss of lower end
4 upper end of sleeve, ball bearing 3 are mounted between end nut 1 and sleeve 4.Nut 12 is threadedly coupled with attachment screw 11, such as Fig. 2 institute
Show.
As shown in Fig. 2, the kidney slot installation attachment screw 11 that its side wall of sleeve 4 opens up.
The component that tension spring 6, hook 7, pin 8 and T-connecting piece 13 form, can be with whole set replacement.In use, passing through hook
Hook 7 is inserted into the deformed part in the middle part of locking locking plate by the chamfering that 7 lower ends open up, and two hooks, 7 lower end is led to contract at this time
Upper end is caused to expand outwardly.Tension spring 6 is elongated at this time, and the pulling force of generation is by the inside upper end for tensing hook 7, when 7 lower end of hook is arrived
It in the middle part of up to locking locking plate when the lower end surface of deformed part, will expand outwardly, make the hook formation of 7 lower end of hook is promptly anti-to uncage
The lower end of deformed part in the middle part of piece；It in the circular hole that spanner 2 opens up on end nut 1 and can move left and right, to adjust rotation
The arm of force, O-ring 10 are mounted in one end of spanner 2, can prevent spanner 2 from deviating from from end nut 1；End nut 1 is rotated by spanner 2,
Threaded connection may be implemented lifting handle 5 and move up and down, to drive by tension spring 6,13 institute of hook 7, pin 8 and T-connecting piece
The component of composition is mobile simultaneously.When moving up lifting handle 5 with specific direction rotation end nut 1, it can realize that pull-out is anti-
It uncages the movement of piece；Ball bearing 3 is installed between end nut 1 and sleeve 4 can reduce rotation friction；Backing plate 9 is soft Buddhist nun
Imperial material, 4 lower end of sleeve is fixed in stickup, to prevent disfiguring workpiece surface；Sleeve 4 is used as lever, offers on side wall specific
The kidney slot of length and width is passed through while attachment screw 11 connects lifting handle 5 and T-connecting piece 13 and is opened up on sleeve 4
Kidney slot, can to avoid lifting handle 5 with end nut 1 with turning and control the stroke of attachment screw 11；After removing nut 12, from
In sleeve 4, lifting handle 5 and T-connecting piece 13 extract out attachment screw 11, can from 4 lower end overall pulling down of sleeve by tension spring 6,
Component composed by hook 7, pin 8 and T-connecting piece 13.For the locking locking plate for being adapted to various specifications, it can be processed various specific
The hook 7 of length and width, and it is adapted to tension spring 6, pin 8 and T-connecting piece 13, to form multiple components.It is connected by dismounting
Screw 11 and nut 12 can complete the replacement of component, and the head of attachment screw 11 and the side of nut 12 offer annular knurl,
In order to tighten by hand and unscrew；After the completion of dismantlement work, after the rotation adjustment of end nut 1 adjusts screw 11 to appropriate location,
Nut 12 is tightened, a whole set of specific purpose tool can be fixed, is prevented loose.
The function and effect of each part of the specific purpose tool are as follows:
