Description of the drawings
Fig. 1 is a kind of wedge pin pin pulling device structure schematic diagram of the present invention,
Fig. 2 is the sectional view of Fig. 1,
Fig. 3 is the right view of Fig. 1.
Specific implementation mode
For ease of those skilled in the art understand that technical solution of the present invention, in conjunction with Figure of description to the technology of the present invention side
Case is described further.
As shown in Figures 1 to 3, a kind of wedge pin pin removal, including screw rod 2 of pulling pin, described 2 one end of screw rod of pulling pin, which is provided with, pulls out
Hook 6 is cased with fixes sleeve 1 and rotating nuts 3 outside screw rod 2 of pulling pin, and 3 end face of the rotating nuts and fixes sleeve 1 are close,
It is provided with plane bearing 14 on rotating nuts 3 and the close end face of fixes sleeve 1, rotation is connected on 3 lateral surface of rotating nuts
Handle 5；This structure converts the linear movement for screw rod 2 of pulling pin to the rotation of rotating nuts 3, then the rotation of rotating nuts 3 is turned
The strength that the needs pulled pin consume is saved in the rotation for turning to handle 5, while but also operation of pulling pin is simpler.
As illustrated in fig. 1 and 2, screw rod 2 of pulling pin includes threaded shank 11 and the polished rod portion 10 of integrally connected, described to pull out the setting of hook 6
In end of the polished rod portion 10 far from threaded shank 11,10 diameter of polished rod portion is less than threaded shank 11, and threaded shank 11 is far from polished rod portion 10
End set has round fixed block 4；10 diameter of polished rod portion is set smaller than threaded shank 11, is for the ease of screw rod 2 of pulling pin by solid
Determine to take out in sleeve 1, threaded shank 11 and polished rod portion 10 are wholely set, and are enhanced the intensity for screw rod 1 of pulling pin, are made it will not in pulling pin
Situations such as being broken.
As shown in Fig. 2, the fixes sleeve 1 includes sleeve 8 and fixed column 9,9 end face of the fixed column is set as taper
Face 12,8 end face of sleeve are welded with taper surface 12；The setting of taper surface 12 convenient for sleeve 8 be close to fixed column 9 and with fixed column 9
Welding, avoids sleeve 8 from being slided on 9 end face of fixed column.
As shown in Fig. 2, 11 outer diameter of threaded shank of 9 internal diameter of the fixed column and screw rod 2 of pulling pin is adapted, 8 side of the sleeve
Face is additionally provided with open slot 7, and 7 width of the open slot is more than 2 diameter of screw rod of pulling pin；Open slot 7 is arranged, and person easy to operation is from opening
Mouthful slot 7 observation screw rod 2 of pulling pin is pulled pin situation, is avoided pulling out hook 6 and is fallen off and do not know from pin.
It is arranged fluted on the end face of plane bearing 14 as shown in Fig. 2, the rotating nuts 3 are arranged, plane bearing 14 is set
In in groove, the depth of groove is less than 14 thickness of plane bearing, and plane bearing 14 is located at end face and fixing sleeve outside groove
9 end face of fixed column of cylinder 1 is adjacent to；The setting of plane bearing 14 effectively reduces the friction between rotating nuts fixed column in March 9
Power and abrasion, while being also conducive to reduce the dynamics that the rotation of rotating nuts 3 needs.
Such as Fig. 1 to 3, two symmetrical U-lags 13 are provided on 3 lateral surface of the rotating nuts, 5 one end of the handle is placed in
In a wherein U-lag 13, it is additionally provided with the mounting hole for being horizontally through U-lag 13 in the rotating nuts 3, is set in the mounting hole
It is equipped with connection bolt 16, the connection bolt 16 realizes the articulated connection of handle 5 and rotating nuts 3；Two U-lags 13 are set,
In a conduct it is spare, it is described pull pin 2 length of screw rod be more than fixes sleeve 1 and rotating nuts 3 the sum of length so that spiral shell of pulling pin
Bar can stretch out fixes sleeve end and be placed in wedge pin to be pulled out.
As shown in Figures 1 to 3, a kind of wedge pin pin removal of technical solution of the present invention when work, is reversely turned using handle 5
Dynamic rotating nuts 3, or directly hold round fixed block 4 and rotate screw rod 2 of pulling pin so that fixes sleeve is stretched out in 2 end of screw rod of pulling pin
1, and the hook 6 that pulls out for 2 end of screw rod of pulling pin is fixed with wedge pin to be pulled out, then a hand-held fixes sleeve 1, rotates hand on the other hand
Handle 5, realization is pulled pin.
Technical solution of the present invention is exemplarily described invention above in conjunction with attached drawing, it is clear that the present invention implements
It is not subject to the restrictions described above, as long as the various unsubstantialities for using inventive concept and technical scheme of the present invention progress change
Into, or it is not improved the design of invention and technical solution are directly applied into other occasions, in protection scope of the present invention
Within.
