Abstract
The present invention relates to an adjustable bolt electrical heating rod. The defects are overcome that a current bolt electrical heating rod has a constant length, is only suitable for heating bolts with one length specification and cannot meet the requirements of heating bolts with a plurality of length specifications. The adjustable bolt electrical heating rod comprises a front heat insulation segment, a heating segment and a back heat insulation segment which are connected in order. The back heat insulation segment is connected with a connection segment capable of position adjustment through axial movement with respect to the back heat insulation segment, the maximum external diameters of the front heat insulation segment and the connection segment are both larger than the external diameter of the heating segment, and the maximum external diameters of the front heat insulation segment and the connection segment are adaptive to the aperture of the bolt bore. The connection segment is axially moved with respect to the back heat insulation segment so that the length between the front heat insulation segment and the back heat insulation segment is changed and the apparent length of the heating segment is changed, and the length of the heating is adjusted after an electrical heating rod is inserted into a bolt bore so that the adjustable bolt electrical heating rod is able to adapt heating requirements of bolts with a plurality of length specifications.
Description
Technical field
The present invention relates to a kind of heater, especially a kind of bolt is heated and the adjustable bolt electrically heated rod of adjustable heated length.
Background technology
Bolt electric heating rod is that turbine bolt mounting or dismounting are heaters of heating, and conventional sieve i bolt electrically heated rod mainly in design is considered coordinating of heating rod diameter and bolt bore, and generally getting gap is 0.5-1.0mm. Heating rod is divided into three parts, and lower length is mainly considered insulation, prevents because resistance wire too closely produces arc phenomenon with tail end metal shell distance; Heating rod middle part is bringing-up section, and heading-length is in order to adapt to the heating needs of different length bolt; Heating rod top is the section of heating not, and the section of heating does not mainly prevent heat transmission, avoids terminal box handle place temperature superelevation, causes handle internal wiring Yin Gaowen to occur the softening short circuit phenomenon causing of cable.
But existing bolt electric heating rod is all regular length, a kind of heating rod of specification length can only heat for a kind of bolt of length specification, cannot adapt to the bolt heating needs of other length specifications.
And, existing bolt electrically heated rod middle part heading-length is excessive, cause the outer interlock of bolt position also heated, make interlock position occur extra-stress, and owing to can directly causing also heated expansion of flange section after this position heating, thereby make bolt entirety be subject to extra effect of stress, finally may damage bolt. Simultaneously, long heating rod cannot be avoided contacting with the hole wall of bolt bore in actual use, when heating rod is vertically placed, the upper position of heating rod bringing-up section and bolt bore hole wall are collided, when horizontal positioned, the middle part of bringing-up section and bolt bore hole wall are collided, and heating rod contacts with building bolt endoporus hole wall and can cause the local thawing of bolt bore. For low-expansion coefficient, high-intensity high temperature resistant novel cobalt-based material, as Alloy783, exist notch sensitivity relatively large, the King Wen such as anti-fatigue ability is relatively poor, the defect that problems causes will become the origin place of crackle, and causes bolt fracture.
Summary of the invention
The invention solves existing bolt electrically heated rod is regular length, can only adapt to heat a kind of bolt of length specification, cannot adapt to the defect of the bolt heating needs of different lengths specification, a kind of adjustable bolt electrically heated rod is provided, can regulate the actual heated length of pars intermedia bringing-up section, thereby adapt to the bolt heating needs of different lengths specification.
The present invention has also solved existing bolt electrically heated rod and can contact with the hole wall of bolt bore in actual use, cause the outer interlock of bolt position heated, make interlock position occur the defect of extra-stress, a kind of adjustable bolt electrically heated rod is provided, the front-end and back-end of middle part bringing-up section are provided with the adiabatic section that size strengthens, thereby control the reasonable clearance between bringing-up section and bolt bore hole wall, prevent contact, thereby avoid the outer interlock of bolt position heated.
The technical solution adopted for the present invention to solve the technical problems is: a kind of adjustable bolt electrically heated rod, comprise the front adiabatic section, bringing-up section and the rear adiabatic section that are connected successively, on rear adiabatic section, connect can be relatively after adiabatic section move axially the linkage section of adjusting position, the maximum outside diameter of front adiabatic section and the maximum outside diameter of linkage section are all greater than the external diameter of bringing-up section, and the aperture of the maximum outside diameter of front adiabatic section and the maximum outside diameter of linkage section and bolt bore is suitable.
