Abstract
A flange bolt disassembly device comprises a main bolt sleeve which is matched with a flange bolt needing to be disassembled in shape, a connection cord of which one end is connected with the side wall of the main bolt sleeve, a rotary shaft of which the shaft body is vertically connected with the other end of the connection rod, an outer sleeve of which one end is radially symmetrically provided with through holes for allowing the rotary shaft to penetrate, an inner sleeve arranged at the other side in the outer sleeve opposite to the rotary shaft, a spring arranged in the outer sleeve and connected with one end of the rotary shaft and one end of the inner sleeve with both ends, a secondary bolt sleeve which is matched with the flange bolt needing to be disassembled in shape, wherein the outer sleeve, the connection rod and the main bolt sleeve form pivot shaft connection; one end of the inner sleeve is protruded out of the outer sleeve; the side wall of the secondary bolt sleeve is connected with one end, protruded out of the outer sleeve, of the inner sleeve. The flange bolt disassembly device solves the problems that the flange assembly and disassembly efficiency is low and the multiple persons are required for operation in the pipeline overhaul process.
Description
Technical field
The utility model relates to pipe-line equipment maintenance field, particularly a kind of flange bolt provision for disengagement.
Background technology
At present, in pipe-line equipment maintenance process, usually need flange to dismantling and installing.But in actual maintenance process, be all manually to utilize light instrument to dismantle and install conventionally.Concrete grammar is that a people utilizes spanner or pipe vice to be fixed bolt in this one end of flange bolt, and another people utilizes spanner to dismantle nut in flange nut one end simultaneously.For current installing/dismounting technology, exist installing/dismounting efficiency not high, and increase the problems such as human cost.
Summary of the invention
The purpose of this utility model is to provide a kind of flange bolt provision for disengagement, solve in pipeline maintenance process, remove and install the efficiency of flange low, need many people operational issue.
For achieving the above object, the technical solution of the utility model is:
A kind of flange bolt provision for disengagement, it comprises, kingbolt cover, the flange bolt of its profile and required dismounting matches; Connecting rod, its one end is connected with described kingbolt cover sidewall; Rotating shaft, its axis body and vertical connection of described connecting rod one end; Outer sleeve, its one end radial symmetric is established the through hole wearing for described rotating shaft, and outer sleeve is pivotally connected with connecting rod and the formation of kingbolt cover by rotating shaft; Inner sleeve, is arranged at the opposite side of phase countershaft in described outer sleeve, and inner sleeve one end protrudes from outer sleeve; One spring, is arranged in described outer sleeve, and its two ends are connection rotating shaft and inner sleeve one end respectively; Secondary bolt sleeve, its sidewall is connected with the inner sleeve one end that protrudes from described outer sleeve, and the flange bolt of described secondary bolt sleeve profile and required dismounting matches.
The utility model is adjusted the angle of kingbolt cover by rotating shaft, make kingbolt cover meet the angle of the bolt of required dismounting, and regulate the position of outer sleeve and inner sleeve by spring, kingbolt cover and secondary bolt sleeve can be arranged on smoothly need the bolt of dismounting with for fixing bolt.
The utility model has the advantage of:
The utility model utilizes mechanical balance principle, bolt one end of required dismounting is fixed, in the time applying rotatory force to nut, the frictional force producing is delivered on the bolt of required dismounting, utilizes and is arranged on for the fixture on fixing bolt, and power is transduceed at the bolt for fixing, stop and need the bolts and nuts of dismounting to rotate together, make staff can dismantle alone nut and bolt, increased the efficiency that removes and installs flange, reduced human cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the use state diagram of the utility model embodiment.
Fig. 3 is the use state profile of the utility model embodiment.
The specific embodiment
Referring to Fig. 1～Fig. 3, a kind of flange bolt provision for disengagement of the present utility model, it comprises, kingbolt cover 1, the flange bolt of its profile and required dismounting matches; Connecting rod 2, its one end is overlapped 1 sidewall with described kingbolt and is connected; Rotating shaft 3, its axis body and described connecting rod vertical connection of 2 one end; Outer sleeve 4, its one end radial symmetric is established the through hole wearing for described rotating shaft 3, and outer sleeve 4 forms pivotally connected by rotating shaft 3 and connecting rod 2 and kingbolt cover 1; Inner sleeve 5, is arranged at the opposite side of the interior phase countershaft 3 of described outer sleeve 4, and inner sleeve 5 one end protrude from outer sleeve 4; One spring 6, is arranged in described outer sleeve 4, and its two ends are connection rotating shaft 3 and inner sleeve 5 one end respectively; Secondary bolt sleeve 7, its sidewall is connected with inner sleeve 5 one end that protrude from described outer sleeve 4, and the flange bolt of described secondary bolt sleeve 7 profiles and required dismounting matches.
When use, adjust the angle of kingbolt cover by rotating shaft, make kingbolt cover meet the angle of the bolt of required dismounting, and regulate the position of outer sleeve and inner sleeve by spring, kingbolt cover and secondary bolt sleeve can be arranged on smoothly need the bolt of dismounting with for fixing bolt.
Referring to Fig. 3, in the time applying rotatory force to nut 9, produce to such an extent that frictional force is delivered on the bolt 8 of required dismounting, utilize and be arranged on for the flange bolt provision for disengagement on fixing bolt, power is conducted at the bolt for fixing, stop and need the bolt 8 of dismounting to rotate together with nut 9.
The utility model utilizes mechanical balance principle, makes staff can dismantle alone nut and bolt, has increased the efficiency that removes and installs flange, has reduced human cost.
