Summary of the invention
The present invention has overcome the deficiencies in the prior art, a kind of extracting tool for built-in part is provided, and the instrument in the past that solved can not be used for the built-in parts dismounting of different sizes, the larger and awkward problem of limitation.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: for the extracting tool of built-in part, comprise pressing plate, left hook, right hook, linkage board, screw screw and elevating lever, described left hook and outside, right hook bottom are provided with grab, described pressing plate two ends are provided with chute, described left hook and right hook upper end are respectively through chute I, and left hook and right hook can vertical liftings, described linkage board end is provided with chute II equally, the described screw that screws is connected with left hook and right hook upper end through chute II, and screw screw upper end and be clamped on linkage board upper surface, described linkage board middle part is provided with tapped through hole, described elevating lever is provided with the external screw thread coordinating with tapped through hole, and elevating lever is positioned at pressing plate upper center through tapped through hole posterior end, described elevating lever upper end is welded with the bar of shaking hands.
The width of described chute I equals the width of left hook or right hook.
Described pressing plate upper center is provided with locating hole, and described elevating lever lower end is positioned at locating hole.
The upper surface of described grab is horizontal plane.
Described left hook and right hook all adopt 30CR material to make.
Compared with prior art, the invention has the beneficial effects as follows: this extracting tool for built-in part of the present invention's design, the spacing of left hook and right hook is adjustable, thereby go for the dismounting of the built-in part of different-diameter size, thereby make tool availability stronger, and the present invention is simple in structure, easy to use, can for convenience detachly change long service life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Label in figure is: the bar of 1, shaking hands; 2, elevating lever; 3, screw screw; 4, chute II; 5, linkage board; 6, chute I; 7, pressing plate; 8, left hook; 9, grab; 10, locating hole; 11, right hook.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.Embodiments of the present invention include but not limited to the following example.
Embodiment 1
The extracting tool for built-in part as shown in Figure 1, comprise pressing plate 7, left hook 8, right hook 11, linkage board 5, screw screw 3 and elevating lever 2, described left hook 8 and right hook 11 outsides, bottom are provided with grab 9, described pressing plate 4 two ends are provided with chute 6, described left hook 8 and right hook 11 upper ends are respectively through chute I 6, and left hook 8 and right hook 11 can vertical liftings, described linkage board 5 two ends are provided with chute II 4 equally, the described screw 3 that screws is connected with left hook 8 and right hook 11 upper ends through chute II 4, and screw screw 3 upper ends and be clamped on linkage board 5 upper surfaces, described linkage board 5 middle parts are provided with tapped through hole, described elevating lever 2 is provided with the external screw thread coordinating with tapped through hole, and elevating lever 2 is positioned at pressing plate 7 upper center through tapped through hole posterior end, described elevating lever 2 upper ends are welded with the bar 1 of shaking hands.
When the present embodiment uses, left hook 8 and right hook 11 lower ends are extend into axle endoporus, pipeline, drilling rod connector, valve bodies etc. need maintenance or change in the object of built-in part, the grab 9 of left hook 8 and right hook 11 lower ends is stuck in to sealing ring, packing ring, bearing, the lower end of the built-in parts such as filter, treat that grab 9 clamps, pressing plate 7 two ends are pressed in the upper end open end of object, be used for supporting whole device, grasp and shake hands bar 1 and rotate the bar 1 of shaking hands, elevating lever 2 raises in rotation, drive linkage board 5 to move upward simultaneously, when linkage board 5 moves upward, left hook 8 and 11 interlocks of right hook move upward, thereby grab 9 upwards promotes built-in part in rising, until pull out built-in part completely, the apparatus structure of the present embodiment is simple, arrange rationally, built-in part only can move vertically in the time of dismounting, can reduce dismounting difficulty and the damage to built-in part, convenient disassembly is quick simultaneously, built-in part, maintenance part is well protected simultaneously, can repeatedly utilize, one people can take out built-in part, practical.
In the time that needs are dismantled the built-in part of different size dimensions, left hook 8 and right hook 11 can be moved axially to adjusting along chute I at pressing plate 4, in the time being adjusted to applicable dismounting, to screw screw 3 and be tightened on linkage board 5 upper ends, screw screw 3 left hook 8 and right hook 11 entirety are clamped on linkage board 5, can be used for built-in part dismounting; By the built-in parts of the detachable different size of above step, make this tool availability more extensive, and regulate and use all very convenient, the parts on instrument can singlely be changed, and have reduced the waste of material, and greatly extend service life.
The present embodiment has been optimized following structure on the basis of embodiment 1: the width of described chute I 6 equals the width of left hook 8 or right hook 11.
Vertical in order to guarantee left hook 8 and 11 maintenances of right hook in the present embodiment, while making to dismantle, left hook 8 and right hook 11 are stable, keep grab 9 can clamp all the time built-in part, so the width of chute I 6 equals the width of left hook 8 or right hook 11, thereby can keep left hook 8 and right hook 11 existence very close to each other with chute I 6 close contacts, guarantee that left hook 8 and right hook 11 keep stable in the time of vertical lifting.
Embodiment 3
The present embodiment has been optimized the structure of pressing plate on the basis of embodiment 1 or embodiment 2, is specially: described pressing plate 7 upper center are provided with locating hole 10, and described elevating lever 2 lower ends are positioned at locating hole 10.
The locating hole 10 of the present embodiment can well be located elevating lever 2, avoid elevating lever 2 axially to occur tilting when rotated, thereby damaged screw also can avoid elevating lever 2 to clamp simultaneously, affect the problem that device uses, improved and installed overall stability and security.
The present embodiment is further optimized on the basis of above-mentioned arbitrary embodiment, is specially: the upper surface of described grab 9 is horizontal plane.
The grab 9 of the present embodiment because needs clamp built-in part and drive it to rise, so be horizontal plane by the upper surface of grab 9, can guarantee that grab 9 is interior to be well clamped on built-in part lower end and unlikely dropping, guarantee normally carrying out of dismounting.
The present embodiment has done following optimization on the basis of above-mentioned arbitrary embodiment: described left hook 8 and right hook 11 all adopt 30CR material to make.
In the present embodiment, 30CR can use after modified or normalizing, can increase its wear-resistant and intensity rub resistance, not only can reduce the degree that left hook 8 and right hook 11 damage, increase the service life of left hook 8 and right hook 11, also can guarantee that grab 9 uses for a long time and indeformable, assurance device can not lose efficacy simultaneously.
Be as mentioned above embodiments of the invention.The present invention is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, within all falling into protection scope of the present invention.
