Abstract
The utility model discloses an automatic tripping gear for a lifting hook. The automatic tripping gear comprises a cover plate, a tripping body and a pull rod, wherein the tripping body is divided into an upper U-shaped section with a leftward opening and a lower supporting section; the pull rod is provided with an annular boss, and a spring is sleeved below the annular boss; the pull rod penetrates through the supporting section from bottom to top, then is inserted into the upper U-shaped section to the boss, and finally butts against the upper end of a hole in the supporting section; a steel wire rope hole is formed at the lower end of the pull rod; and the cover plate is provided with a pull rod hole through which the pull rod penetrates, and is fixed on the bottom of the supporting section to seal the spring in the hole of the supporting section. The automatic tripping gear has the beneficial effects that a steel wire rope can be automatically tripped when the pull rod is pulled downwards, so that the automatic tripping gear is simple to operate and is safe and reliable.
Description
Technical field
The utility model relates to the suspension hook technical field, particularly a kind of suspension hook automatic decoupling device.
Background technology
In the building engineering work progress, when steel structure such as pillar are installed, usually adopting steel rope directly to tack pillar lifts by crane, install after putting in place, after the installation, climb up pillar by the workmen and take out the steel rope mode, have that operation easier is large, labour intensity is high, length consuming time, inefficiency, a dangerous shortcoming such as large.
The utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of suspension hook automatic decoupling device, and automatically-unhooked after can making things convenient for lifting construction to finish.
The technical solution adopted in the utility model is such: a kind of suspension hook automatic decoupling device, comprise cover plate, unhook body and pull bar, it is opening U-shaped section and the supporting section of bottom left that described unhook body is divided into top, an annular boss is set and socket spring under it on the described pull bar, then pass from bottom to top that supporting section inserts U-shaped section epimere always until boss is resisted against the upper end, hole in the supporting section, the pull bar lower end is provided with threaded hole of steel, and described cover plate is provided with the tie rod hole that passes for pull bar and is fixed on the supporting section bottom spring is enclosed in the hole of supporting section.
As preferably, also have some screw holes on the described cover plate, cover plate is fixed in the supporting section bottom by screw.
Described pull bar passes the part and the U-shaped section common annular that consists of a sealing that supporting section inserts U-shaped section epimere.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: can by spurring pull bar downwards, can make steel rope automatically-unhooked, simple to operation, safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of mark 3 among Fig. 1.
Fig. 3 is the birds-eye view of mark 1 among Fig. 1.
Mark among the figure: 1 is cover plate, and 11 is screw hole, and 12 is tie rod hole, and 2 is spring, and 3 is pull bar, and 31 is boss, and 32 is threaded hole of steel, and 4 are the unhook body.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment: as shown in Figure 1, a kind of suspension hook automatic decoupling device comprises cover plate 1, unhook body 4 and pull bar 3, and it is opening U-shaped section and the supporting section of bottom left that described unhook body 4 is divided into top.
As shown in Figure 2, an annular boss 31 is set on the described pull bar 3, and at its lower socket spring 2, passes from bottom to top then that supporting section inserts U-shaped section epimere until boss 31 is resisted against the upper end, hole in the supporting section always.The structure of boss 31 is set specifically as shown in Figure 2 on the pull bar 3.
As shown in Figure 3, also have some screw holes 11 on the described cover plate 1, cover plate 1 is fixed in the supporting section bottom by screw.
Described pull bar 3 passes the part and the U-shaped section common annular that consists of a sealing that supporting section inserts U-shaped section epimere.
In lifting steel structure process, first steel rope is pierced in U-shaped section of unhook body 4, pull bar 3 pins steel rope under the effect of spring 2, avoid in the hoisting process steel rope from the 4 interior slippages of unhook body.
After lifting action was finished, the workmen can be on the ground by the steel wires pulling pull bar 3 in the threaded hole of steel 32 that penetrates pull bar 3 bottoms, and spring 2 is compressed, pull on steel wire until the 4 flexibly and comfortably slippages of interior steel rope of unhook body out.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
