Abstract
The utility model aims to provide a kind of suspension hook with anti-drop device, comprise suspension hook body, tongue piece, inhibiting device, tongue piece is movably hinged on suspension hook body, described inhibiting device is the rectangle frame structure that comprises position-limited edge, one end is fixed on the point of connection place on tongue piece, form T character form structure with tongue piece, the other end, through suspension hook body, is connected with position-limited edge; The length of inhibiting device is slightly smaller than the longest distance of point of connection to suspension hook body outside.The utility model is made simple, can directly on existing suspension hook, transform, and cost is low, easy to use, can greatly improve the safety of factory's reinforcement hoisting crane.
Description
Technical field
The utility model relates to the suspension hook of weight-lifting equipment, is specifically related to a kind of suspension hook with anti-drop device.
Background technology
Press workshop hoisting crane (driving), in the time of die hoisting, in order to prevent hung mould and suspension hook disengagement, increases tongue piece conventionally on suspension hook, throws off in order to restriction.But in actual use,, tongue piece can, because connecting device is loosening or be subject to external force, effect of inertia while rising and carry out left and right, outwards mobilely cause throwing off suspension hook, lose limitation function, has great potential safety hazard.
Utility model content
The utility model is intended to solve the safety issue of said structure, and a kind of suspension hook with tongue piece and inhibiting device is provided, and this suspension hook limits the motion of tongue piece by inhibiting device, and tongue piece is remained and the contacting of suspension hook, and avoids lifting rope to depart from suspension hook.
The technical scheme that the utility model technical solution problem adopts is as follows: a kind of suspension hook with anti-drop device, comprise suspension hook body, tongue piece, inhibiting device, tongue piece is movably hinged on suspension hook body, described inhibiting device is the rectangle frame structure that comprises position-limited edge, one end is fixed on the point of connection place on tongue piece, form T character form structure with tongue piece, the other end, through suspension hook body, is connected with position-limited edge; The length of inhibiting device is slightly smaller than the longest distance of point of connection to suspension hook body outside.
The Length Ratio point of connection of described inhibiting device is to the little 4～15mm of longest distance in suspension hook body outside.
Inhibiting device is fixed on tongue piece by welding or bolt.
The end of described tongue piece is resisted against the inner side of the bill of suspension hook body.
Inhibiting device of the present utility model can be made of the less dead-soft steel round steel of diameter, makes simple, with low cost.
The structure that the utility model is combined with inhibiting device at tongue piece, sway or the outside mobile situation that causes lifting rope to throw off suspension hook of having avoided tongue piece to occur in actual use, tongue piece is movably hinged on suspension hook body, the stop gear of tongue piece and inhibiting device composition can rotate taking hinged place as axle center, because the length of inhibiting device is slightly smaller than the longest distance of point of connection to suspension hook body outside, when general state, inhibiting device is under self gravitation, its position-limited edge contacts in the position that approaches bottom with suspension hook body, tongue piece is resisted against the bill inner side of suspension hook body, be subject to the restriction of suspension hook body, inhibiting device can not continue to rotate, therefore the tongue piece connecting as one with inhibiting device is also restricted and can not upwards departs from suspension hook body, in the time that needs are sling goods, the upwards rotation of inhibiting device, and tongue piece move downward unrestricted, therefore as long as this stop gear of rotating limit device and tongue piece composition, just lanyard can be placed in suspension hook, then decontrol suspension hook, inhibiting device and tongue piece just under Action of Gravity Field on the restriction site in suspension hook body, thereby ensured that the lifting rope that hangs weight can not depart from suspension hook.And, the setting of this spacing position, also help make whole suspension hook body in hoisting heavy in vertical state, make suspension hook be difficult for tilting, further reduced weight and hauled out the risk of suspension hook.
In sum, suspension hook provided by the utility model, can avoid suspension hook tongue piece in handling weight process to throw off the situation that causes lifting rope to be deviate to the left and right and outwards effectively, has greatly improved the safety of factory's reinforcement hoisting crane; Meanwhile, the utility model is made simple, can directly on existing suspension hook, transform, and cost is low, easy to use, has a good application prospect.
Brief description of the drawings
Fig. 1 is the constructional drawing of the utility model with the suspension hook of anti-drop device.
In figure, each several part sequence number and title are as follows:
1 is suspension hook body, and 2 is tongue piece, and 3 is inhibiting device, and 4 is position-limited edge, and 5 is point of connection.
Detailed description of the invention
Further illustrate the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, comprise suspension hook body 1, tongue piece 2, inhibiting device 3 with the suspension hook of anti-drop device; Tongue piece 2 is movably hinged on suspension hook body 1, and described inhibiting device 3 is the rectangle frame structure that comprises position-limited edge 4, and one end is fixed on point of connection 5 places on tongue piece 2, forms T character form structure with tongue piece 2, and the other end, through suspension hook body 1, is connected with position-limited edge 4; The Length Ratio point of connection 5 of described inhibiting device 3 is to the little 4～15mm of longest distance in suspension hook body 1 outside; The end of described tongue piece 2 against with the outside of the bill of suspension hook body 1.
The utility model is as follows with the suspension hook use procedure of anti-drop device: in the time of needs hook weight, stir inhibiting device 3 or tongue piece 2, tongue piece 2 is rotated, leave bill, the lifting rope that hangs weight is inserted in suspension hook; Unclamp suspension hook, inhibiting device 3 or tongue piece 2 reset under Action of Gravity Field, the position-limited edge 4 of inhibiting device 3 contacts near the position of bottom with suspension hook body 1 outside, tongue piece 2 ends prop up bill inner side, be subject to the restriction of suspension hook body, inhibiting device can not continue to rotate, and therefore the tongue piece connecting as one with inhibiting device is also restricted and can not upwards departs from suspension hook body; When handling completes need to shift out lifting rope time, stir inhibiting device 3 or tongue piece 2, make tongue piece 2 leave bill, take out lifting rope.
