Abstract
The utility model discloses a hydraulic fitting bolt, which comprises a stretching bolt, wherein a bolt rod with taper is arranged at the middle part of the stretching bolt, two ends of the stretching bolt are provided with external screw threads matched with the lock nuts, an expansion taper sleeve is mounted on the bolt with taper, and a taper corresponding with the taper of the bolt rod is arranged at the internal periphery of the expansion taper sleeve. The utility model has the advantages of reasonable structure, good operating effect and convenient mounting and disassembly.
Description
Technical field:
The utility model relates to a kind of bolt.
Background technique:
Existing plain bolt when connecting large-sized flange, can not produce desirable stable being rigidly connected, the installing/dismounting trouble.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, good working effect, the hydraulic pressure fitting-up bolt of easy installation and removal.
Technical solution of the present utility model is:
A kind of hydraulic pressure fitting-up bolt, it is characterized in that: comprise turnbuckle, the intermediate portion of turnbuckle is the screw rod that has tapering, the two ends of turnbuckle have the outside thread that cooperates with locking nut, the expansion tapered sleeve is housed having on the screw rod of tapering, has in week and the corresponding tapering of screw portion tapering in the expansion tapered sleeve.
The utility model is rational in infrastructure, good working effect, easy installation and removal.During use, adpting flange is through accurate centering, and axially clamp until its Metal Contact, put into turnbuckle and lining in the bolt hole together with hand, enter tapered sleeve by the stretching stretching screw, and the radial expansion of extrusion expansion tapered sleeve, interference fit formed with screw, then with its further relatively wherein nut carry out axial tension and reach the pretension load, again the another nut is manually tightened with the round bar spanner.The expansion of bolt and pretension during installation, all adopting accurately, controlled hydraulic elongator carries out.During Bolt dismantling, discharge bolt pretightening, adopt creosoting process to discharge the expansive force of tapered sleeve then with hydraulic elongator.Need oil hydraulic pump band pressure gauge, extreme pressure hose, rapid pipe joint etc. during to hydraulic elongator pressurization and creosoting process release tapered sleeve.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of hydraulic pressure fitting-up bolt, comprise turnbuckle 1, the intermediate portion of turnbuckle is the screw rod 2 that has tapering, the two ends of turnbuckle have the outside thread that cooperates with locking nut 3,4, expansion tapered sleeve 5 is housed having on the screw rod of tapering, has in week and the corresponding tapering of screw portion tapering in the expansion tapered sleeve.
