Abstract
The utility model discloses an auto -lock hook assembly, including colluding the body, anticreep spare and wire rope, collude the internal auto -lock chamber that has, anticreep spare articulates the auto -lock intracavity is provided with the torsional spring that makes anticreep spare open in articulated department, the inner of anticreep spare has the pull rod, wire rope inserts the auto -lock chamber through the upper end of coupler body, wire rope is last to have and prevents that wire rope breaks away from the knot of coupler body, pull rod and wire rope connect. This hook assembly has improved the stability of anticreep spare greatly, improves the anticreep effect.
Description
Technical field
The utility model belongs to technical field of municipal construction, relates to a kind of self-locking hook device.
Background technology
Suspension hook is modal a kind of suspender in elevator machinery.Suspension hook often by means of member hangs such as assembly pulleys on the steel rope of lifting mechanism.Suspension hook is provided with anti-falling piece usually, and anti-falling piece is hinged on coupler body, and arranges torsion spring in hinged place, is being linked into by after the lifting rope that falls on thing, and the opening that anti-falling piece blocks suspension hook departs from suspension hook to prevent lifting rope.This suspension hook is easy to when anti-falling piece encounters foreign matter because of carelessness be opened, and there is larger potential safety hazard.
Summary of the invention
The utility model proposes a kind of self-locking hook device for prior art Problems existing, and object is the stability improving anti-falling piece in suspension hook, improves anticreep effect.
The utility model is achieved in that
A kind of self-locking hook device, comprise and hook body, anti-falling piece and steel rope, it is characterized in that, in described hook body, there is self-locking chamber, described anti-falling piece to be hinged in described self-locking chamber and to be provided with the torsion spring that anti-falling piece is opened in hinged place, and the inner of described anti-falling piece has pull bar, and described steel rope inserts self-locking chamber by the upper end of coupler body, described steel rope has the knot preventing steel rope from departing from coupler body, described pull bar is connected with steel rope.
Preferably, described pull bar is connected with described steel rope by tightrope.
Preferably, the inner end of described steel rope has butting section, and described steel rope is arranged with spring, and the lower end abutment of described spring is on butting section, and the upper end of described spring is resisted against on the roof in self-locking chamber.
A kind of self-locking hook device provided by the utility model, when falling to haul goods thing, under the Action of Gravity Field of goods, steel rope moves up relative to coupler body until knot abuts on the roof in self-locking chamber, steel rope can pull pull bar to rotate around the hinged place of anti-falling piece, thus drive anti-falling piece to turn to the aperture position of coupler body, such anti-falling piece has just blocked the opening of coupler body, when anti-falling piece encounters foreign matter because of carelessness, need the gravity overcoming goods just can open anti-falling piece, so just substantially increase the stability of anti-falling piece, improve anticreep effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model cargo hook gear.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Present embodiments provide a kind of self-locking hook device, as shown in Figure 1, comprise and hook body, anti-falling piece 200 and steel rope 300, in described hook body, there is self-locking chamber 110, steel rope 300 inserts in self-locking chamber 110 by the upper end of coupler body 100, the part that steel rope 300 inserts in self-locking chamber 110 is insertion section, insertion section has knot 310, and knot 310 can be movable and can prevent steel rope 300 from departing from coupler body 100 in self-locking chamber 110.Anti-falling piece 200 is hinged in self-locking chamber 110, is provided with the torsion spring that anti-falling piece 200 can be made to open in this hinged place, and that is, under the effect not having external force, anti-falling piece 200 is in open mode under the effect of torsion spring.The inner of anti-falling piece 200 has pull bar 210, has angle between pull bar 210 and anti-falling piece 200, and angle angular range is preferably 75-105 degree, and pull bar 210 is connected with steel rope 300 by tightrope 220.
When falling to haul goods thing, under the Action of Gravity Field of goods, steel rope 300 moves up relative to coupler body 100 until knot 310 abuts on the roof in self-locking chamber 110, steel rope 300 can pull pull bar 210 to rotate around the hinged place of anti-falling piece 200, thus drive anti-falling piece 200 to turn to the aperture position of coupler body 100, such anti-falling piece 200 has just blocked the opening of coupler body 100, when anti-falling piece 200 encounters foreign matter because of carelessness, need the gravity overcoming goods just can open anti-falling piece 200, so just substantially increase the stability of anti-falling piece 200, improve anticreep effect.When goods fall to move to position put down goods time, drag hook loses the gravity of goods, and under the effect of torsion spring, anti-falling piece 200 is opened automatically, easily can unload goods.
Further, the inner end of steel rope 300 has butting section 320, steel rope 300 is arranged with spring 330, and the lower end abutment of spring 330 is on butting section 320, and the upper end of spring 330 is resisted against on the roof in self-locking chamber 110.Because steel rope 300 is comparatively hard, be not easy to need larger power could move in self-locking chamber 110, spring 330 can assist torsion spring to open anti-falling piece 200.
Should be understood that; the foregoing is only preferred embodiment of the present utility model; be not sufficient to limit the technical solution of the utility model; for those of ordinary skills; within spirit of the present utility model and principle; can be increased and decreased according to the above description, replaced, converted or improved, and all these increases and decreases, replacement, conversion or the technical scheme after improving, all should belong to the protection domain of the utility model claims.
