As shown in Fig. 1-5 or 7, the technical solution that present embodiment provides is as follows, comprising:
Claw pulling mechanism 2, for extract be disassembled part 200, the claw pulling mechanism 2 include multiple pull rods 22 and with multiple pull rods
The adjusting bracket 21 of 22 one end connection, the other end of multiple pull rods 22 are disassembled part 200 for catching on；
Anti-drop device 3, for preventing claw pulling mechanism 2 from breaking off relations, which includes set on multiple 22 peripheries of pull rod
Frame body 31 and the first propulsion arm 33 on frame body 31, first propulsion arm 33 contact after passing through frame body 31 with pull rod 22；
Driving mechanism 4, for providing removal force, which is set to adjusting bracket 21 and is fixed between part 100.
Wherein, being disassembled part 200 can be shaft coupling, flange, bearing or other cover parts, and fastening is linked in solid
Determine on part 100, retaining element 100 is generally axis, bar.
Wherein, driving mechanism 4 is linear motion, can be electric cylinders, cylinder, oil cylinder, hydraulic cylinder, jack, preferably thousand
Jin top.
Wherein, the shape of frame body 31 can be regular polygon, preferably equilateral triangle, the quantity and drawing of the regular polygon
The quantity of bar 22 is consistent.
Wherein, claw pulling mechanism 2 includes multiple pull rods 22, and one end of multiple pull rods 22 is connect with adjusting bracket 21, and the other end is used
It is disassembled part 200 in catching on, and driving mechanism 4 is used to withstand retaining element 100, after retaining element 100 is withstood, pulling claw
Mechanism 2, which is caught on, is disassembled part 200, and when driving mechanism 4 works, piston rod stretches out, and leads to be disassembled part 200 relative to fixation
The directly raw relative displacement of part 100, splits out so that part 200 will be disassembled.
And pull rod 22 perpendicular contact of the first propulsion arm 33 of anti-drop device 3 after frame body 31 with claw pulling mechanism 2, it is pulling out
During drawing, pull rod 22 is resisted by the first propulsion arm 33, to prevent pull rod 22 from loosening outward.
Anti-drop device 3 first can be placed on pull rod with unrestricted choice, before operation by the position of anti-drop device 3
22 periphery is preferably placed at the hook portion of pull rod 22, can reach best stressed effect.
Present embodiment, the anti-drop device 3 of the periphery by the way that claw pulling mechanism 2 is arranged in, can pull out to avoid claw pulling mechanism 2
The problem of loosening is easily deformed during drawing.
As the further preferred of present embodiment, the adjusting bracket 21, which is equipped with, opens distance for adjusting yoke 22
Regulating tank 23, regulating tank 23 is preferably radial arrangement, and the quantity of regulating tank 23 is consistent with the quantity of pull rod 22, pull rod 22
One end is sticked in regulating tank 23, and the other end is disassembled part 200 for catching on.
By this preferred embodiment, pull rod 22 can move freely in regulating tank 23, can be conveniently adjusted pull rod 22
Opening amplitude meets the disassembly of different part sizes.
As shown in fig. 7, baffle 24 can be arranged far from the end of anti-drop device 3 in pull rod 22, spiral shell is set on baffle 24
Bolt, so that pull rod 22 is fastened in regulating tank 23 and connecting with baffle spiral shell mosquito.
As the further preferred of present embodiment, it can be equipped with the second propulsion arm 25 on the adjusting bracket 21, described the
Two propulsion arms 25 contact after passing through adjusting bracket 21 with the pull rod 22 in regulating tank 23, further anticreep.
As the further preferred of present embodiment, anti-drop device 3 can also include adjustable plate 32 and be set in frame body 31
Guide groove 34, when frame body 31 be regular polygon when, guide groove 34 can be set to regular polygon interior vertex, adjustable plate 32 block
Together in the guide groove 34, adjustable plate 32 is equipped with the threaded hole for installing the first propulsion arm 33.
Wherein, the length of adjustable plate 32 can be plurality of specifications, as shown in fig. 7, adjusting when selecting biggish adjustable plate 32
Save plate 32 position will toward moving down because guide groove 34 be it is tapered, it is more bigger down, so when using biggish adjusting
When plate 32, adjustable plate is forced to move down, and can be adapted for lesser part disassembly at this time, and the first propulsion arm 33 passes through adjustable plate 32,
Because guide groove 34 is taper, after the first propulsion arm 33 resists pull rod 22, reaction force can be generated on adjustable plate 32, led
Adjustable plate 32 and guide groove 34 is caused to be in close contact, to realize anticreep.It, can be with, whereas if when selecting lesser adjustable plate 32
It is applicable in biggish part disassembly.
As shown in figure 4, show the utility model another embodiment, present embodiment the difference is that:
Frame body 31 is regular polygon, preferably regular triangular, and guide groove 34 is set to the interior vertex of regular polygon, the first top
Push rod 33 passes through frame body 31 and adjustable plate 32 is threadedly coupled, and is equipped with third propulsion arm 35 in the center on 31 side of frame body, preferably
For screw rod, pass through after frame body 31 be disassembled part 200 and contact.When part is smaller, because the first of polygon vertex
The length of propulsion arm 33 is often inadequate, even and if length it is enough, as too long and rigidity is insufficient, at this point it is possible to not more
It changes on the basis of frame body 31, frame body 31 is rotated, third propulsion arm 35 is made to be directed at pull rod 22, directly utilize third propulsion arm 35,
Pull rod 22 is resisted, to prevent pull rod 22 from breaking off relations.
First propulsion arm described in embodiment of above, the second propulsion arm and third propulsion arm can be screw rod.
As it can be seen that can be used for dismantling the tighter shaft coupling of shaft hole matching, flange, bearing or other by the utility model
When cover parts, due to being provided with anti-drop device 3 in structure, it can be easily deformed the problem of loosening to avoid claw pulling mechanism 2, greatly
It improves work efficiency greatly；
Also, the utility model can adapt to wider size by adjustable plate 32 and the guide groove 34 in frame body 31
Part disassembly in range；
Also, the utility model will not generate additional radial clamping force in use, i.e., will not be to axial disassembly
Power impacts, to reduce input power.
It should be noted that, in this document, the terms "include", "comprise" or its any other variant are intended to non-row
His property includes, so that the process, method, article or equipment for including a series of elements not only includes those elements, and
And further include other elements that are not explicitly listed, or further include for this process, method, article or equipment institute it is intrinsic
Element.
Specific case used herein is expounded the principles of the present invention and embodiment, above example
Illustrate the method and its core concept for being merely used to help understand the utility model.The above is only the preferred implementations of the utility model
Mode, it is noted that due to the finiteness of literal expression, and objectively there is unlimited specific structure, for the art
Those of ordinary skill for, without departing from the principle of this utility model, can also make it is several improve, retouching or become
Change, above-mentioned technical characteristic can also be combined in the right way；These improve retouching, variation or combination, or without changing
Other occasions are directly applied to by the conception and technical scheme of utility model, are regarded as the protection model of the utility model
It encloses.
