Description
Technical field
The present invention relates to a kind of unilateral bolt fastener auxiliary mounting tool, especially relate to a kind of split nested type
Unilateral bolt fastener installs adaptor.
Background technology
Current in civil construction and mechanical erection field, the installation requirements amount that structural member connects fastening is big.Just
For the bolt commonly used at present, when implementing to connect terminal operation to component, staff needs simultaneously at structure
The operation of part both sides, is still the best implementation method for monolateral mounting means.This method for fastening connection structure
It is simple and convenient to operate, carries, but be only applicable in opening section component, in some special occasions, such as
To closed cross-section member or inconvenience when the component that other side operates is attached fastening, just cannot use this
Conventional bolt and nut method for fastening connection.And on domestic market, there is no corresponding monolateral bolt product, public
The Patents opened or weaken shank of bolt too much or bolt head stress point is very few, foreign market has been similar to product
Product, but above-mentioned existing patent or product are all difficult to, at erection stage, bolt is applied bigger pretension to form friction
Type bolt joint, the comprehensive mechanical property of its carrying is unsatisfactory, is subject in Anti-quake Architectural Structure Design is applied
To considerable restraint.
Applicant has obtained a kind of split Nested-type single-side bolt fastener of mandate national inventing patent, and (grant number is
103671447B), this patent can realize unilateral operation, the connection completing structural member and fastening.General installation side
In formula, directly electric wrench sleeve is connected with nut, it is impossible to ensure that bolt does not rotates.When bolt occurs to turn
Time dynamic, the frictional force existed between bolt and split type pad can cause split type pad generation sliding to rotate, it is impossible to
Several pieces of pads are made to be uniformly distributed and make unbalance stress.Contact friction force when between pad and connector is not enough simultaneously
Time, bolts and nuts are easy to rotate together, it is impossible to the torque value reaching to set completes installment work.
It is electronic that the patent of Application No. 2015108219651 discloses a kind of split Nested-type single-side bolt fastener
Installation tool, is used for installing split Nested-type single-side bolt fastener, and this instrument includes main body and is arranged in main body
Input mechanism and output mechanism, described output mechanism includes output shaft inner sleeve and is set in its outside output
Outer shaft sleeve cylinder, described output shaft outer sleeve outer wall is provided with and engages, with input mechanism, the first gear being connected, described
Output shaft inner sleeve is fixed in main body, and during installation, output shaft outer sleeve is connected with nut, output shaft inner sleeve with
Bolt connects, and input mechanism rotation is also rotated by the first gear driven output shaft outer sleeve, makes output shaft inner sleeve
Produce relative rotation with output shaft outer sleeve, so that screw bolt and nut relatively rotates.
But the output shaft outer sleeve of this instrument is the gear by outer wall engages with input mechanism, this structure takies sky
Between big；Fixing reliability between output shaft inner sleeve and main body is the highest.
It is thus desirable to a kind of suitably adaptor, it is possible to realize fixing during installing bolt motionless while twist
Jack panel.
