Heated type bolt dismantling device
Technical field
The utility model relates to a kind of provision for disengagement, is specifically a kind of heated type bolt dismantling device.
Background technology
Generating set is large with bolt volume, during installation, for making its faying face produce the prestressing force requiring, need to overlap top nut it is heated, and its expanded by heating is extended, and then by hand nut is screwed to precalculated position.While unclamping nut maintenance, need to heat bolt equally, it is extended, just can back out nut.The earliest, the heating of bolt is manually to use spray gun to face toward the heating of bolt hole flame, and manual control flame size and flame color, by experience and length heating estimated time, can not effectively be controlled heating-up temperature, make bolt cross thermal oxide and damage; At present, bolt heating is general adopts electric bolt electric heating rod to heat, and is the resistance heated rod inserting bolt centre bore will with resistance wire, by resistance wire, generates heat, radiation heating bolt bore surface, thereby heating bolt, though this mode of heating heat time can be controlled, the heat time is longer, and sometimes because heating current and heat time are controlled inaccurate, make electric bolt electric heating rod short circuit and puncture, can not take out, and making the problem of bolt failure.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides that a kind of efficiency is high, firing rate is fast, the life-span is long, the reliable heated type bolt dismantling device of handling safety.
In order to solve above technical problem, the utility model provides a kind of heated type bolt dismantling device, comprise spanner, heater coil, radiator, power module and shell, the chuck of spanner is fixed on the front end face of shell, power module is arranged on the middle rear end of shell, the wire of heater coil is connected with power module through the front end face of shell, and radiator is wrapped in the outside of heater coil wire, and heater coil is load coil.
The technical scheme that the utility model further limits is:
Further, the coated at least one deck metal aluminum foil in load coil surface.
Further, the outer surface of load coil is evenly placed with feet along its cross-sectional circumferential direction.
Further, the junction of load coil and its wire is provided with heat guard.
Further, the top of heat guard is provided with load coil insertion depth adjuster.
Further, load coil is the HTSC coil being arranged in vacuum chamber.
The utility model can adopt existing device or module as corresponding units completely, and its composition is linked together and can realize technique scheme, therefore practical.
The beneficial effects of the utility model are: the utility model unites two into one spanner and firing equipment, convenient to use, the heating of employing induction coil, its firing rate and security performance are obviously better than the Resistant heating using at present, by heat guard, completely cut off heat and be delivered to miscellaneous part, the spike on surface makes induction coil can, too near a side, not make homogeneous heating and safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: spanner 1, HTSC coil 2, radiator 3, power module 4, shell 5, wire 6, feet 7, heat guard 8, depth adjuster 9, metal aluminum foil 10.
The specific embodiment
embodiment 1
A kind of heated type bolt dismantling device that the present embodiment provides, comprise spanner 1, be arranged on the HTSC coil 2 in vacuum chamber, radiator 3, power module 4 and shell 5, the chuck of spanner 1 is fixed on the front end face of shell 5, power module 4 is arranged on the middle rear end of shell 5, the wire 6 of HTSC coil 2 is connected with power module 4 through the front end face of shell 5, radiator 3 is wrapped in the outside of wire 6, the HTSC coil 2 coated multiple layer metal aluminium foils 10 in surface, outer surface at HTSC coil 2 is evenly placed with feet 7 along cross-sectional circumferential direction, HTSC coil 2 is provided with the junction of wire 6 heat guard 8 that micro-porous calcium silicate is made, the top of heat guard 7 is provided with HTSC coil 2 insertion depth adjusters 9.
During use, first by HTSC coil 2 inserting bolt centre bores, according to bolt length, the degree of depth that stretches into that regulates HTSC coil 2 by depth adjuster 9, starts to heat bolt, although heating-up temperature is high after adjusting, duration is long, but heat guard 8 can stop heat to be delivered on wire 6 well, until bolt, be heated to and specify after requirement, directly the adjustable wrench by provision for disengagement unloads bolt.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
