The specific embodiment
Below in conjunction with embodiment the present invention is done to specify further, but embodiment of the present invention is not limited thereto.
Embodiment
Shown in Fig. 1～3, the present invention mainly is made up of dead man 1, said dead man 1 whole cylindrical structure.Be provided with external screw thread 2 in the lower end of said dead man 1, this external screw thread 2 matches with internal thread on the alignment pin 14, during use with the screw-internal thread fit on this external screw thread 2 and the alignment pin 14, thereby dead man 1 is screwed in alignment pin 14 inside, like Fig. 1, shown in 3.
On said dead man 1, also be provided with bracing frame, support frame as described above comprises supporter 3, and this supporter 3 is the cylindrical structural of inner hollow, and promptly its cross section is an annulus, and this supporter 3 is enclosed within on the dead man 1.The interior ring circular diameter of said supporter 3 is greater than the diameter of dead man 1, and promptly dead man 1 is a matched in clearance with the interior ring of supporter 3, and dead man 1 is free to rotate in supporter 3.Simultaneously, on said supporter 3, also be provided with top board 4, said top board 4 is arranged on the top of supporter 3, and with supporter 3 structure that is solidified as a whole.On said top board 4, then be provided with the through hole 5 that matches with dead man 1; Said top board 4 through this through hole 5 be enclosed within on the dead man 1 after dead man 1 cooperates; And the diameter of this through hole 5 is also greater than the diameter of dead man 1; Promptly this through hole 5 also is a matched in clearance with dead man 1, and then dead man 1 also can freely rotate in the through hole 5 of top board 4.
For the ease of dead man 1 is positioned on the top board 4, thereby on dead man 1, form a strong point,, on said dead man 1, also be provided with dead man axle neck 6 so that rotate dead man 1.Said dead man axle neck 6 is whole cylindrical, and this dead man axle neck 6 and dead man 1 structure that is solidified as a whole.Simultaneously, the diameter of this dead man axle neck 6 is greater than the diameter of through hole 5, and this dead man axle neck 6 is positioned at the top of top board 4.During use, the external screw thread of dead man 12 is screwed in the internal thread of alignment pins 14, then the lower surface of dead man axle neck 6 is fitted on the upper surface of top board 4, the fixed-site of dead man 1 this moment on top board 4.Be rotated further dead man 1, then under the effect of the screw thread that cooperatively interacts, dead man 1 invariant position, 14 of alignment pins move upward, thereby alignment pin 14 is extracted from the pin-and-hole of equipment.
Height for the ease of adjustable support body 3; Thereby be convenient to extract the bigger alignment pin of length 14, on said supporter 3, also be provided with height adjustable ring 7, said height adjustable ring 7 overall structures are identical with supporter 3; Should height adjustable ring 7 also be the cylindrical structural of inner hollow promptly; Its cross section also is an annulus, and the interior ring diameter of this annulus is also greater than the diameter of dead man 1, and then dead man 1 can rotate at these height adjustable ring 7 internal freedoms.For the ease of regulating height; Be provided with in the lower end of said supporter 3 and highly regulate external screw thread; On said height adjustable ring 7, be provided with simultaneously with this and highly regulate the height adjusting internal thread that external screw thread is complementary; Said supporter 3 is connected on the height adjustable ring 7 after highly regulating external screw thread and highly regulate screw-internal thread fit through it; Highly regulate internal thread and highly regulate the height that external screw thread cooperates thereby can regulate, be i.e. the whole height of adjustable support body 3 and height adjustable ring 7 according to the length needs of alignment pin 14.
For the ease of rotation dead man 1, thereby extract alignment pin 14, also be provided with runner assembly in the upper end of said dead man 1, said runner assembly comprises handle 8.In order to increase moment of torsion,, between said handle 8 and dead man 1, also be provided with connecting rod 9 so that use littler torsion to rotate dead man 1.For the ease of connecting rod 9 one ends are connected on the dead man 1, the other end with this connecting rod 9 is connected on the handle 8 simultaneously, is respectively equipped with attaching parts at said connecting rod 9 two ends, and 9 on said connecting rod is connected on dead man 1 or the handle 8 through attaching parts.Said attaching parts comprise the pin 11 that connects connecting rod 9 and dead man 1 or handle 8, and this pin 11 passes connecting rod 9 and dead man 1 or handle 8, thereby connecting rod 9 is connected with dead man 1 or handle 8, and is as shown in Figure 2, and should can rotate by pin 11.11 to deviate from order preventing to pin, to be provided with pin cap 10 at these 11 1 ends of pinning, this pin cap 10 and pin 11 structure that is solidified as a whole, thus make the structure of this pin cap 10 and a unitary pin of pin 11 formation.Simultaneously, then be provided with pad 12 at these 11 other ends of pinning, this pad 12 is connected on the pin 11 through screw 13.For the ease of dismounting and assembling, said screw 13 is a sunk screw.
During use; Height adjustable ring 7 is placed on the alignment pin 14 that need extract directly over; Be about to pin pulling out device integral body of the present invention be placed on the alignment pin 14 that need extract directly over, simultaneously according to the length adjustment height adjustable ring 7 of alignment pin 14 and the whole height of supporter 3.With the pin between connecting rod 9 and the dead man 1 11 is that the center rotates connecting rod 9, and promptly pivot link 9 in perpendicular makes connecting rod 9 and dead man 1 perpendicular.With the screw-internal thread fit of external screw thread 2, screw in the direction swing handle 8 of the internal thread of alignment pin 14 then along external screw thread 2, simultaneously even handle 8 rotates around dead man 1 with alignment pin 14; This moment, handle 8 was perpendicular and parallel with dead man 1 with connecting rod 9, so that the operator is to handle 8 firmly as shown in Figure 1; Connecting rod 9 then forms the arm of force; And connecting rod 9 passes to dead man 1 with the torsion of swing handle 8, through the arm of force effect of connecting rod 9, uses 8 of less torsion swing handles on dead man 1, to form bigger rotatory force; This rotatory force screws in dead man 1 in the alignment pin 14 after overcoming the frictional force between the internal thread of external screw thread 2 and alignment pin 14; Then dead man 1 moves downward, and is fitted on the upper bottom surface of top board 4 up to the bottom surface of dead man axle neck 6, and is as shown in Figure 1.Be that the center rotates handle 8 with the pin between handle 8 and the connecting rod 9 11 then; Make handle 8 and connecting rod 9 be straight line; Promptly this handle 8 and connecting rod 9 form the arm of force with the perpendicular integrative-structure of dead man 1; Thereby increased the arm of force, promptly used identical torsion then can increase the moment of torsion of dead man 1, made swing handle 8 more laborsaving.Continuation is around dead man 1 swing handle 8; Then connecting rod 9 rotates with handle 8; Can drive simultaneously dead man 1 rotates; Dead man 1 continues to screw in the alignment pin 14 under the effect of the external screw thread that cooperatively interacts 2 and the internal thread of alignment pin 14, and dead man 1 no longer moves downward under the effect of dead man axle neck 6, and then alignment pin 14 moves upward.Continue swing handle 8, deviate from the pin-and-hole of equipment, then alignment pin 14 is extracted up to alignment pin 14.The interaction of the external screw thread 2 of internal thread through the alignment pin 14 that cooperatively interacts and dead man 1 is at last extracted alignment pin 14 from dead man 1, so that the present invention uses next time.
As stated, just can realize the present invention preferably.
