Description
Technical field
The present invention relates to engineering fishing device, fixture is salvaged in especially a kind of engineering construction.
Background technique
During engineering construction, such as cut-pff wall, diaphram wall pore-forming (slot) and in pile foundation pore forming process, often
Drill bit, draw tube occurs to property, connects sand hopper or the cable of fracture crashes into the accidents such as slot, these objects must take out out of slot
Come, otherwise can not carry out next step construction.Currently, there is no special fishing tool in construction, the tool of field fabrication is utilized
Partial component can be salvaged, but since some Components Shapes are irregular, the material is soft, cause clamping highly difficult out,
Influence subsequent construction.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of engineering construction salvage fixture, can fast salvaging junk,
Operation is simple.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
A kind of engineering construction salvaging fixture, outer sleeve, inner cylinder and screw rod including ecto-entad setting, wherein
Outer sleeve and inner cylinder are slidably connected and are locked by retaining mechanism；
Inner cylinder connect with wire rod thread, drives inner cylinder to move up and down relative to outer sleeve by screw rod；
The outer sleeve lower end and inner cylinder lower end are along the circumferential direction uniformly surrounded with multiple connecting rods, multiple clamping bars, housing respectively
Cylinder, connecting rod, multiple clamping bars and inner cylinder successively hingedly constitute four-bar mechanism.
The screw rod end is equipped with antiskid thread.
The retaining mechanism includes the positioning sliding block being mounted on outer sleeve inner wall, and positioning sliding block is convex shape structure, convex
Character form structure two sides sleeveless jacket is equipped with dentation spring pad, and corresponding position is equipped with the groove being adapted with positioning sliding block in inner cylinder,
The dentalation being meshed with dentation spring pad is equipped in groove.
The clamping bar includes pole, and pole inner lower edge is equipped with anti-slop serrations, is equipped with multiple lance hooks on the outside of pole.
The multiple clamping bar constitutes handgrip, and two opposite clamping bars are equipped with hook on handgrip.
The clamping bar is magnet steel.
Fixture is salvaged in a kind of engineering construction of the present invention, is had following technical effect that
1) it, by setting outer sleeve and inner cylinder, and is slided using screw rod, realizes the opening or purse up of lower end handgrip, in addition grab
It is additionally provided with lance hook, hook on hand, in this way, to different components, it can be achieved that clamping, hooking or a combination of both, to realize quick
By component salvage come, high-efficient, opening or purse up additionally, due to handgrip can be adjusted at any time, thus with lance hook, support
When hook cooperates, it can quickly be adjusted, improve the flexibility of salvaging.
2), by setting dentation spring pad, it can be achieved that the clamping in a normal state of outer sleeve and inner cylinder, so as to retaining clip
Hold state；The opposite sliding in force, and then realize the opening or purse up of handgrip, this adjustment process moves automatic with screw rod
It carries out, therefore easy to operate.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples:
Fig. 1 is schematic diagram of the invention.
Fig. 2 is the schematic diagram of clamping bar in the present invention.
Fig. 3 is the schematic diagram of dentation spring pad in the present invention.
Schematic diagram when Fig. 4 is retaining mechanism locking state in the present invention.
In figure: outer sleeve 1, inner cylinder 2, screw rod 3, retaining mechanism 4, connecting rod 5, clamping bar 6, antiskid thread 7, positioning sliding block 8,
Dentation spring pad 9, pole 10, anti-slop serrations 11, lance hook 12, hook 13.
Specific embodiment
As shown in Figs 1-4, fixture is salvaged in a kind of engineering construction, outer sleeve 1, inner cylinder 2 including ecto-entad setting and
Screw rod 3, wherein outer sleeve 1 is slidably connected with inner cylinder 2 and is locked by retaining mechanism 4；Inner cylinder 2 and 3 screw thread of screw rod connect
It connects, drive inner cylinder 2 to move up and down relative to outer sleeve 1 by screw rod 3；1 lower end of outer sleeve and 2 lower end edge of inner cylinder circle
Circumferential direction is uniformly surrounded with multiple connecting rods 5 respectively, and every 5 end of connecting rod and 6 middle part of clamping bar are hinged, the corresponding clamping bar 6
End and 2 lower end of inner cylinder are hinged, in use process, grasp outer sleeve, by rotary screw, turn screw rod and drive inner cylinder
Opposite outer sleeve slides up and down, so that the handgrip for forming clamping bar opens accordingly or purse up, to realize to different component
Clamping is salvaged.
3 end of screw rod is equipped with antiskid thread 7.Thus structure avoids hand from skidding in rotary screw 3.
The retaining mechanism 4 includes the positioning sliding block 8 being mounted on 1 inner wall of outer sleeve, and positioning sliding block 8 is in sliding process
Positioning action is played, guarantees inner cylinder with respect to outer sleeve vertical shift.Positioning sliding block 8 is convex shape structure, convex shape structure two
Side sleeveless jacket is equipped with dentation spring pad 9, and corresponding position is equipped with the groove being adapted with positioning sliding block 8 in inner cylinder 2, sets in groove
There is the dentalation being meshed with dentation spring pad 9.Dentation spring pad and inner cylinder in the non-moving condition of inner cylinder, outer sleeve
Dentalation engagement on body, realizes the limit to the two axial direction, and after rotary screw, inner cylinder generates becoming for forward movement
Gesture, dentalation exert a force to dentation spring pad, and after power reaches certain value, dentation spring pad and dentalation deform,
And then relatively move, realize that dentalation is engaged with next dentation spring pad, while inner cylinder moves forward a tooth pitch.This
For sample in inner cylinder forward continuous motion process, the dentalation on inner cylinder slips over dentation spring pad one by one, when arrival refers to
Positioning postpones, and dentalation is engaged with dentation spring pad, achievees the purpose that lock again.
The clamping bar 6 includes pole 10, and 10 inner lower edge of pole is equipped with anti-slop serrations 11, is equipped with multiple lance hooks on the outside of pole 10
12.During being clamped for general component, anti-slop serrations can be improved chuck(ing) capacity, prevent component from sliding.When to frame
When the outer junk of frame is salvaged, the handgrip that clamping bar is constituted can be extend into outside frame inside junk, then by moving down
Cylinder realizes the opening of handgrip, and lance hook realizes the hook to junk outside frame, to smoothly lift component, pull out.
The multiple clamping bar 6 constitutes handgrip, and two opposite clamping bars 6 are equipped with hook 13 on handgrip.When junk is fracture
When cable, when handgrip clamps cable, two hooks of clamping bar bottom end are drawn close and are mutually staggered, and form shearing clamping,
In this way by above grab, it is lower folder form secondary clamping, guarantee the secured of cable clamping, and once press from both sides out.
The clamping bar 6 is magnet steel.Due to drill bit, draw tube, connect sand hopper etc. for steel production, by be arranged magnet steel, clamping
It is attracted each other in the process using magnetic force, improves clamping effect.
