Abstract
The utility model discloses a fracture bolt remove device, including cylindrical hollow sleeve pipe (1), open afterburning pole jack (2) that have along radially running through sleeve pipe (1) on the pipe wall of sleeve pipe (1) one end, during the use, sleeve pipe (1) that will prefabricate is a disconnected silk bolt hole shen ru, and the welding rod is by deep in the sleeve pipe (1), then welds (sleeve pipe (1) external diameter should be less than diameter of bolt 10mm) to a disconnected contact point. Disconnected silk is taken out with afterburning pole rotary casing (1) in the firm back of welding. The utility model discloses it is swift convenient to use, has reduced workman's intensity of labour, the timely equipment hidden danger that has got rid of, and the success rate is high, and is especially high to bolt success rate more than the M30, can effectively solve the bolt fracture problem of taking out.
Description
Technical field
This utility model is related to break bolt, takes out the device of break bolt especially with welding manner.
Background technology
In the running of equipment, because of unit vibrations, screw-in bolt is stretched stress and shear stress for a long time,
Thus causing screw-in bolt fracture, bolt fracture causes great hidden danger to equipment.Because the general bolt of main equipment screws in length
Degree is longer, and screw thread cooperation is closely and bolt hardness is big, and current withdrawing device for broken threaded parts cannot meet requirement it is impossible to complete task.
Content of the invention
The technical problems to be solved in the utility model is：A kind of break bolt withdrawing device is provided, is suitable for screw-in length
Longer break bolt is taken out, the device that particularly cooperation welding manner takes out, and success rate is high, and operation is simple.
The technical solution of the utility model is as follows：
A kind of break bolt withdrawing device, including cylinder type hollow sleeve pipe, the tube wall of sleeve pipe one end has and radially passes through
The afterburning bar jack of sleeve-penetrating.The external diameter of sleeve pipe generally little than bolt external diameter 10mm, during use by said structure without plus
In one end insertion bolt fracture hole of power bar jack, then from sleeve pipe hollow intracavity, sleeve pipe is welded with fracture of wire intersection,
After the completion of, with the afterburning bar jack rotation of round steel side insertion, exit the bolt of fracture.
Groove along sleeve pipe axial direction is had on the inwall of sleeve pipe.In order to improve the convenient of sleeve pipe internal cavity welding further
Property, reduce difficulty, be conveniently accurately positioned solder joint by opening groove in inwall.
Described groove has four, and the angle such as annular sleeve inwall circumference is distributed.The axis of groove length direction presss from both sides two-by-two
90 degree of angle, according to circumstances may be selected two of which during welding, the end of three or four grooves is welded.
Sleeve outer wall is provided with movable loop, and the collar comprises a coned face, coned face has same with casing axis
The circular scale of axle.External diameter due to sleeve pipe is less than the external diameter of bolt, therefore not necessarily can keep after insertion bolt hole and break
Silk is coaxial, for this reason, one movable loop carrying taper seat of processing, can be along sleeve outer wall slide anteroposterior, its taper seat being capable of portion
Point insertion bolt hole, meanwhile, using the circular scale on taper seat surface confirm sleeve pipe whether coaxial with bolt hole (for bolt
The axially bored line situation vertical with equipment surface, when circular scale overlaps interval scale sleeve pipe also with bolt hole together with bolt hole aperture
Axle).
Afterburning bar jack at least two, and the axis angle of two neighboring reinforcing bar jack is 90 degree, setting is multigroup to be added
Power bar jack is to insert from all directions.
This utility model completes to be connected with the welding of faying face at bolt fracture of wire using internal surface of sleeve pipe, the afterburning bar jack of cooperation
Easily fracture of wire bolt can be screwed out, time saving and energy saving, success rate is high, simple to operate.
Brief description
Fig. 1 is principle schematic of the present utility model；
Fig. 2 and Fig. 3 is the structural representation that this utility model carries movable loop and groove.
Specific embodiment
As shown in figure 1, a kind of break bolt withdrawing device, including cylinder type hollow sleeve pipe 1, on the tube wall of sleeve pipe 1 one end
Have the afterburning bar jack 2 extending radially through sleeve pipe 1, afterburning bar jack 2 has 3, and the axis of two neighboring reinforcing bar jack 2
Angle is 90 degree.Groove 3 along sleeve pipe 1 axial direction is had on the inwall of sleeve pipe 1.Groove 3 has four, and annular sleeve 1 inwall is justified
(90 degree) distributions of the angles such as week.Sleeve pipe 1 outer wall is provided with movable loop 4, and the collar 4 comprises a coned face, in coned face
There is the circular scale 5 with sleeve pipe 1 axis coaxle.
