Abstract
The utility model discloses a multi-functional puller. The multi-functional puller comprises a cross rod (1), a screw rod (3) and two vertical supporting rods (2). The supporting rods (2) respectively sleeve two ends of the cross rod (1). The screw rod (3) is in screwed connection with the cross rod (1). The multi-functional puller is characterized in that one end of the screw rod (3) is welded with a top point (4),and the other end of the screw rod (3) is welded with a connecting block (5), a screw (6) is formed on the lower end surface of the connecting block (5), through holes (a) are respectively formed in the connecting blocks (5) and the top point (4); claws (8) are respectively hinged with the lower ends of the supporting rods (2), fixing blocks (9) on both sides of the claws (8) are welded on the supporting rods (2) respectively. Bolt through holes (10) are respectively formed in the fixing blocks (9). The multi-functional puller also serves as a pin puller combining a pulling function and a pin pulling function together, thus multiple functions of a tool are achieved, and use ratio of resource is increased.
Description
Technical field:
The utility model relates to the technical field of drawing yard device, more specifically to the multi-functional yard device that draws of one.
Background technology:
Drawing code, is the instrument often using in flight-line maintenance.It is generally mainly used to the bearing of damage to disassemble vertically from axle, and it is made up of swing handle, screw rod and pulling claw.And drawing now code structure simple, it generally can only realize the code effect of drawing.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of multi-functional yard device that draws is provided, and it can be realized and draw code function, can realize the effect of pulling pin again.
Technology solution of the present utility model is as follows:
A kind of multi-functional yard device that draws, comprise cross bar, screw mandrel and two vertical support bars, two support bar two ends of sleeve cross bar respectively, screw mandrel is screwed onto on cross bar, that one end of screw mandrel is welded with is top, the other end is welded with contiguous block, on the lower surface of contiguous block, form screw rod, described contiguous block and the top upper through hole that all forms; The lower end of described support bar is hinged with hook, is all welded with fixed block on the support bar of hook both sides, forms bolt through-hole on fixed block.
Screw flight rotation direction on described contiguous block is contrary with the screw thread thread rotary orientation of screw mandrel.
The described yard device that draws is provided with a round bar, and round bar sleeve is in the through hole of contiguous block or in top through hole.
The lower surface of described fixed block and the bottom surface of support bar are at grade.
The beneficial effects of the utility model are:
It can be used as draws yard device to can be used as again pin removal, will draw code function and the function of pulling pin to be combined into one, makes an instrument have multiple use function, has improved the utilization rate of resource.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
In figure: 1, cross bar; 2, support bar; 3, screw mandrel; 4, top; 5, contiguous block; 6, screw rod; 7, round bar; 8, hook; 9, fixed block; 10, bolt through-hole; A, through hole.
Detailed description of the invention:
Embodiment: as shown in Figure 1, a kind of multi-functional yard device that draws, comprise cross bar 1, screw mandrel 3 and two vertical support bars 2, two support bar 2 two ends of sleeve cross bar 1 respectively, screw mandrel 3 is screwed onto on cross bar 1, that one end of screw mandrel 3 is welded with is top 4, the other end is welded with contiguous block 5, forms screw rod 6 on the lower surface of contiguous block 5, on described contiguous block 5 and top 4, all forms through hole a; The lower end of described support bar 2 is hinged with hook 8, on the support bar 2 of hook 8 both sides, is all welded with fixed block 9, forms bolt through-hole 10 on fixed block 9.
The thread rotary orientation of the screw rod 6 on described contiguous block 5 is contrary with the screw thread thread rotary orientation of screw mandrel 3.
The described yard device that draws is provided with a round bar 7, and round bar 7 sleeves are in the through hole a of contiguous block 5 or in top 4 through hole a.
The lower surface of described fixed block 9 and the bottom surface of support bar 2 are at grade.
Operation principle: the utility model support bar 2 is inserted on cross bar 1, can take off conversion direction again sleeve to cross bar 1, in the time that support bar 2 is positioned on screw mandrel 3 top 4 one side, put down hook 8, round bar 7 is inserted in the through hole a of contiguous block 5, can be used as two pawls and draw code; And in the time that support bar 2 is positioned on screw mandrel 3 contiguous block 5 one side, hook 8 is overturn upper and round bar 7 is inserted in top 4 through hole a, can be used as a pin removal, and while using as pin removal, first the screw rod on contiguous block 56 is screwed in alignment pin, the bolt through-hole 10 that support bar 2 is passed to fixed block 9 by bolt is fixed on work top to be pulled pin, thereby rotate round bar 7, alignment pin rotation is extracted.
