Abstract
The utility model discloses a novel automatic shackle special for hoisting and relates to a shackle. The novel automatic shackle comprises a U-shaped retaining ring and a pin, wherein the position of the U-shaped retaining ring, which is close to the tail end, is provided with two fastening holes; the first end of the pin can penetrate through the two fastening holes of the U-shaped retaining ring, so that the U-shaped retaining ring is closed; the novel automatic shackle also comprises a pull rod, a sleeve and a spring, wherein the first end of the pull rod is fixedly connected with the second end of the pin; the sleeve is fixedly connected to one side of the U-shaped retaining ring and is sleeved outside the second end of the pin and the pull rod; the second end of the pull rod penetrates through a sleeve cover of the sleeve, which is far away from one end of the U-shaped retaining ring; the tail of the second end of the pull rod is connected with a retaining ring; and one end of the spring is pressed against the tail of the second end of the pin, and the other end of the spring is pressed against the inner side of the sleeve cover of the sleeve, which is far away from one end of the U-shaped retaining ring. The novel automatic shackle has the advantages that the shackle can be automatically loosened and fastened after hoisting is finished and is convenient to use and high in safety performance.
Description
Technical field
The utility model relates to a kind of shackle, especially a kind of automatic shackle of using in hoisting engineering.
Background technology
In hoisting engineering, thing is hung in shackle commonly used and steel rope combination colligation.Shackle commonly used is the shackle of D type, and the shackle of D type be utilize pin with
U-shaped claspButton hole (as shown in Figure 1) that be threaded, lifting puts in place can't be out of stock automatically.After lifting puts in place, must personnel (suspension centre of colligation) goes to untie shackle to the high-altitude.This prior art has the following disadvantages: 1.
U-shaped claspWith being connected in conjunction with the employing bolt of pin, after lifting was finished, the colligation point of steel rope was aerial at height; 2. (suspension centre of colligation) goes to untie shackle to the high-altitude to need personnel, and complex operation is consuming time more of a specified duration, has safety hazard; 3. need personnel to arrive aloft work, the steel rope of loosening needs default people's cat ladder, the expense of the taking a lot of work material gone up.
The utility model content
The new type auto shackle of the lifting special use that the purpose of this utility model provides and a kind ofly can release automatically after finishing lifting, performance easy to use, safe is good.
The technical scheme that the utility model adopts for achieving the above object is: a kind of new type auto shackle that lifts special use, comprise U-shaped clasp and pin, U-shaped clasp is provided with two relative button holes by the end, two button holes that first end of pin can pass U-shaped clasp make U-shaped clasp sealing, described new type auto shackle also comprises pull bar, sleeve and spring, first end of pull bar is captiveed joint with second end of pin, sleeve is fixedly connected on U-shaped clasp one side and is enclosed within outside pin second end and the pull bar, second end of pull bar passes sleeve away from the socket cover of U-shaped clasp one end, the second end end of pull bar is connected with the draw ring that releases, and the second end end of spring one end and pin offsets, the other end and sleeve offset away from the socket cover inboard of U-shaped clasp one end.
Owing to adopt said structure, the special-purpose new type auto shackle of the lifting of the utility model has following beneficial effect:
1, it is more convenient to hang thing in conjunction with the steel rope colligation, and safety performance is better;
2, the pin pressure that is subjected to spring is combined tightr with the button hole of U-shaped clasp;
3, adopt new type auto shackle, the draw ring that releases at the pull bar second end end can connect the rope that releases, can draw the rope that releases on ground after finishing lifting, pin first end is deviate from the button hole of U-shaped clasp, namely be implemented in the purpose that easily releases in ground, cat ladder need not be set climb the operation of releasing to the high-altitude, can save and make the cat ladder expense, guarantee construction safety again;
4, through facts have proved, to compare with adopting fixedly the shackle hanging method, pillar of every lifting can be saved 20 minutes, has saved manually and the mechanical one-shift expense, and economic benefit is obvious.
Below in conjunction with drawings and Examples the special-purpose new type auto shackle of the utility model lifting is described further.

Fig. 1 is prior art shackle structural representation;
Fig. 2 is the structural representation of the special-purpose new type auto shackle closed state of the utility model lifting;
Fig. 3 is the structural representation of the special-purpose new type auto shackle opening of the utility model lifting.
The main element label declaration: first end of first end of 1-U-shaped clasp, 2-pin, 21-pin, second end of 22-pin, 3-sleeve, 4-spring, 5-socket cover, 6-pull bar, 61-pull bar, 62-pull bar second end, 7-draw ring releases.
The specific embodiment
Shown in Fig. 2 to 3, the special-purpose new type auto shackle of the utility model lifting, comprise U-shaped clasp 1 and pin 2, U-shaped clasp 1 is provided with two relative button holes by the end, two button holes that first end 21 of pin can pass U-shaped clasp 1 make U-shaped clasp 1 sealing, described new type auto shackle also comprises pull bar 6, sleeve 3 and spring 4, first end 61 of pull bar is captiveed joint with second end 22 of pin, first end 61 of pull bar is captiveed joint with second end 22 of pin by welding in the present embodiment, and second end 22 of pin is the other end relative with first end 21 of pin.Sleeve 3 is fixedly connected on U-shaped clasp 1 one sides and is enclosed within outside pin second end and the pull bar 6, and sleeve 3 also is to be fixedly connected by welding in U-shaped clasp 1 one sides in the present embodiment.Second end 62 of pull bar passes sleeve 3 away from the socket cover 5 of U-shaped clasp 1 one ends, outstanding socket cover 5 outsides, second end, 62 ends of pull bar are connected with the draw ring 7 that releases, and second end, 22 ends of spring 4 one ends and pin offset, the other end and sleeve 3 offset away from socket cover 5 inboards of U-shaped clasp 1 one ends.The draw ring 7 that releases can connect for the rope (not shown) that releases of threading off.
Pin is subjected to spring 4 pressure under the usual state, and first end 21 of pin inserts in the button hole of U-shaped clasp 1, forms closed state, the steel rope colligation is gone in the U-shaped clasp, steel rope is enclosed in U-shaped clasp 1 interior being blocked by pin and is difficult for deviating from, as Fig. 2, and not shown steel rope.After finishing lifting, need to release, as long as draw the rope that releases that is connected with the draw ring 7 that releases on ground, the rope that releases pulling pull bar 6, spring 4 is subjected to force compresses, pull bar 6 connects pin, second end 22 of pin is drawn first end 21 of back pin to break away from the button hole of U-shaped clasp 1, and steel rope is deviate from from U-shaped clasp 1 opening part, as Fig. 3.Unclamp the rope that releases, namely releasing lever 6, and pin 2 is subjected to spring 4 pressure, and first end 21 of pin snaps in the button hole of U-shaped clasp 1, recover closed state, as shown in Figure 2.
