Abstract
The utility model provides a crampon anti-falling structure which comprises a breaking rope detecting mechanism, a trigger mechanism, and a safety locking mechanism. The breaking rope detecting mechanism is arranged on a crampon steel wire to detect whether steel wire ropes are broken or not. The trigger mechanism arranged between the breaking rope detecting mechanism and the safety locking mechanism is controlled by the breaking rope detecting mechanism and used to trigger the safety locking mechanism. The safety locking mechanism is contacted with the steel wire ropes, and is controlled by the trigger mechanism to clamp the steel wire ropes when the steel wire ropes are broken. The safety locking mechanism is composed of at least two pairs of wedge-shaped sliding ways and two pairs of clamp component parts, wherein the wedge-shaped sliding ways and the clamp component parts are arranged on a pair of steel wire ropes. The wedge-shaped sliding ways are composed of a plurality of strip blocks shaped like the Chinese character ' ba' and are connected with at least one pair of clamps in a movable manner. The corresponding surface of the clamps and the steel wire ropes is a crescent occlusal surface with occlusal teeth shaped like a fishhook with a barb. The crampon anti-falling structure can be used for mechanical lifting equipment.
Description
Technical field
The utility model relates to mechanical equipment technical field, relates in particular to a kind of load hook anti-falling structure.
Background technology
Falling protector is applicable to the safety precaution when preventing from being hung the workpiece accidental falling of overhead traveling crane when lifting, can effectively protect terrestrial operation personnel's life security and be hung the damage of workpiece object, is applied to metallurgical Automobile manufacturing, the industries such as petrochemical complex, engineering construction.Falling protector can be suitable for cargo hoisting limiting the interior snap catch locking of distance dropped object, protection terrestrial operation personnel's life security and hung the damage of workpiece object.Falling protector occlusal surface snap-in force is inadequate at present, and the steel rope coasting distance is large.
Summary of the invention
Technical problem to be solved in the utility model is to provide on above-mentioned crane hook anti-falling structure basis that a kind of snap-in force is larger, the better anti-falling structure of safety.
The utility model be the technical solution problem by the following technical solutions.
A kind of load hook anti-falling structure comprises: the disconnected testing agency that restricts, be installed on the load hook steel wire, and whether rupture for detection of steel rope; Trigger mechanism between disconnected rope testing agency and dead lock for safety mechanism, is controlled by the disconnected testing agency that restricts, and is used for triggering dead lock for safety mechanism; Dead lock for safety mechanism contacts with steel rope, during wire cable rupture, controlled by trigger mechanism, and steel rope is blocked; Dead lock for safety mechanism is made of contract row slideway and clamp component parts by two pairs at least, be installed in respectively on a pair of steel rope, contract row slideway is made of " eight " font stick many, and and at least one pair of clamp be flexibly connected, clamp and steel rope opposite face are the crescent occlusal surface, and occlusal tooth engaged is band hangnail barb-type.
According to an embodiment of the present utility model, the disconnected testing agency that restricts is made of circular arc shift fork and a pair of pulley, and respectively there is a pulley mounting hole at circular arc shift fork two ends, and the centre is the circular arc arm.
According to an embodiment of the present utility model, be the crescent chute in the middle of the circular arc arm.
According to an embodiment of the present utility model, trigger mechanism is two "T"-shaped, is installed in respectively on a pair of steel rope, and "T"-shaped lower end contacts with the disconnected testing agency that restricts, and the upper end contacts with dead lock for safety mechanism.
Because occlusal tooth engaged is band hangnail barb-type, so that the load hook anti-falling structure is more reliable, the strength of interlock steel rope is larger during wire cable rupture, safety and reliability.

Fig. 1 is the utility model embodiment load hook anti-falling structure figure;
Fig. 2 is clamp occlusal surface scheme drawing;
Fig. 3 is Fig. 2 A-A section-drawing;
Fig. 4 is Fig. 2 B-B section-drawing;
Fig. 5 is the stressed scheme drawing of anti-falling structure.
Below pass through the specific embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
The specific embodiment
Referring to Fig. 1 to Fig. 5, a kind of load hook anti-falling structure comprises: the disconnected testing agency 1 that restricts, be installed on the load hook steel rope 7, and whether rupture for detection of steel rope 7; Trigger mechanism 2 between disconnected rope testing agency 1 and dead lock for safety mechanism 3, is subjected to disconnected testing agency's 1 control of restricting, and is used for triggering dead lock for safety mechanism 3; Dead lock for safety mechanism 3 contacts with steel rope 7, during steel rope 7 fracture, is subjected to trigger mechanism 2 controls, and steel rope 7 is blocked; Dead lock for safety mechanism 3 is made of contract row slideway 31 and clamp 32 component parts by two pairs at least, be installed in respectively on a pair of steel rope 7, contract row slideway 31 is made of " eight " font stick many, and and at least one pair of clamp 32 be flexibly connected, clamp 32 and steel rope 7 opposite faces are the crescent occlusal surface, and the tooth engaged of occlusal surface 321 is band hangnail barb-type.
The disconnected testing agency 1 that restricts is made of circular arc shift fork and a pair of pulley 4,5, and respectively there is a pulley mounting hole at circular arc shift fork two ends, and the centre is the circular arc arm.Be the crescent chute in the middle of the circular arc arm.Trigger mechanism 2 is two "T"-shaped, is installed in respectively on a pair of steel rope 7, and "T"-shaped lower end contacts with the disconnected testing agency 1 that restricts, and the upper end contacts with dead lock for safety mechanism 3.
As shown in Figure 5, steel wire is from the inboard process of pulley, and original suspension hook 6 fall lines are constant.During normal operation, steel rope 7 is received suspension hook weight impact, has produced thrust F1 and the F2 of opposite sign but equal magnitude in shift fork pulley 4,5 inboard.Under the effect of these two power, shift fork mediates all the time, not to any one direction motion.Because the native system left-right symmetric, so only analyze on one side.Suppose that F2 diminishes or disappears when the right steel rope 7 fracture, F1 also continues maintenance, and F1 and F2 no longer keep equilibrium relation (F1〉F2).The circular arc shift fork is when stress balance, and it is motionless to remain on midway location, but when being subjected to force unbalance owing to steel rope 7 fractures (F1〉F2), shift fork moves to the direction (upper left side) of F1 along shift fork middle part falcate groove under the effect of F1.When receiving the affecting of shift fork thrust, trigger mechanism 2(is T shape jacking block namely) upward movement, remove to trigger clamping mechanism 3 steel rope 7 clamped.
When wire cable rupture, clamp 32 is subject to the promotion of trigger mechanism 2, along wedge slideway 31 upward movements, two clamps 32 when upward movement, clamping steel wire 7, simultaneously, wedge slideway 31 has produced the effect of drawing tighter and tighter, clenches steel wire.The utility model embodiment uses the tooth engaged of fish hook (band hangnail), in case bite steel wire, under the effect of hangnail, steel wire is held inflexibly, has guaranteed that weight can be from high falling.
By above-mentioned description, the related personnel can under the condition of mentality of designing of the present utility model and technical index appointment, change and revise.Technical scope of the present utility model is not limited to the content on the specification sheets, must determine technical scope according to the claim scope.
