Description
Technical field
The present invention relates to a kind of bolt disassembly instrument, and in particular to bolt dismounts and store under water instrument.
Background technology
In radioactivity occasion, when being related to being bolted, underwater remote disassembly and installation bolt is required for.It is existing underwater
Remote Bolt dismantling technology, which is generally on stock, installs sleeve additional, but the technology can only be dismantled and cannot installed, and spiral shell after dismounting
Bolt easily slides and falls into pond, and also someone improves in above-mentioned technology, and steel ball and spring are added at sleeve, possesses remote
Function is accommodated apart from bolt, but this elastic grappling fixture bulky dimensions, when the spatial joint clearance of bolt and surrounding is very small, it is impossible to
It is reliably completed remote disassembling work.
The content of the invention
It is an object of the invention to solve removing and installing instrument and cannot meeting the underwater long distance of close gap for existing bolt
From removing and installing the problem of requiring, there is provided a kind of underwater dismantling device of bolt to solve the above problems.
The present invention is achieved through the following technical solutions：
The underwater dismantling device of bolt, including operation lever, the elastic grappling fixture that top is fixedly connected with the bottom of the operating lever end；Institute
Stating elastic grappling fixture includes resilient sleeve, the locking sleeve for being arranged on resilient sleeve and being opened for resilient sleeve closure；
The operation lever includes outer tube, and the mobile bar being arranged on inside outer tube；Described resilient sleeve one end is equipped with
Two sliding channels radially set along resilient sleeve, which is provided with extrudes time-varying for locking sleeve
The extruding straight slot that shape compresses；
The mobile bar bottom is stretched into resilient sleeve, and mobile bar bottom terminal ends be provided through two sliding channels and
The stop pin being fixedly connected with locking sleeve；The outer tube bottom is fixedly connected with resilient sleeve.
The present invention can effectively realize bolt head by the cooperation between the resilient sleeve and locking sleeve of elastic grappling fixture
Clamping and relieving.Elasticity grappling fixture of the invention is compact, and possesses nut clamping function, and then can be non-in bolt and surrounding space gap
In the case of often small, bolt disassembly work is reliably completed.Why elastic grappling fixture can accomplish so compact be based in the present invention
Following reason：In the case where not increasing resilient sleeve diameter, by being axially provided with extruding straight slot, shape in the front end of resilient sleeve
Into resilient sleeve, by the extruding of locking sleeve, it can be achieved that resilient sleeve clamps the effect of nut, effect is very notable.
Preferably, two sliding channels are symmetrical arranged along the central axes of resilient sleeve.
Further, torsion resistant device is set in the resilient sleeve, and the torsion resistant device includes being provided with the company of connection straight slot
Female connector cylinder, is fixed on branch sleeve one end end and with extruding the matched rib tooth of straight slot.
Hexagonal prisms hole is provided with position inside the resilient sleeve and between extruding straight slot and sliding channel, should
It is provided between rib tooth and sleeve and the matched hexagonal prisms in hexagonal prisms hole.
The present invention is due to being axially provided with uniformly distributed extruding straight slot in resilient sleeve front end, thus its torsional property substantially drops
Low, in order not to reduce its torsional property, in order to solve the problems, such as that this adds torsion resistant device, which includes branch sleeve
The rib tooth of resilient sleeve is caught in rib tooth, and triangular prism installed in antitorque hexagonal prisms front end, formed small―gap suture coordinates,
The hexagonal prisms hole inside hexagonal prisms and resilient sleeve set in the middle part of torsion resistant device is interference fitted, and is welded as a whole, and can be made
Restriction of the torsion resistant device to resilient sleeve circumferential position is more stablized, and then instrument is born the moment of torsion of bigger.
Further, the quantity of the extruding straight slot is arranged to three, is evenly distributed on the end of locking sleeve；The rib
The quantity of tooth is also configured as three, and the position which is set is corresponding with the position for extruding straight slot.
In order to preferably be operated, it is additionally provided with the operation lever for driving locking sleeve along joystick shaft
The driving device that line direction moves up and down.The driving device is to be fixed on the pneumatic mechanism on operation lever top.The pneumatic motor
Structure top is additionally provided with handle.
It is easier without manual mobile locking sleeve, operation by the setting of said structure.
Preferably, the material of the resilient sleeve is precipitation-hardening stainless steel.
Compared with prior art, the present invention have the following advantages and advantages：
1st, the present invention can in radioactivity or underwater occasion, and it is very small in bolt and surrounding space gap in the case of, energy
It is reliably completed bolt disassembly work；
2nd, the configuration of the present invention is simple, easy to operate, is very suitable for promoting and applying.
