Detailed Description

As shown in fig. 1, 2, 3, 4 and 5, a specific embodiment of an automatic picking and hanging safety sling includes a main body 1, a hanging nail 2 and a driving device 3 mounted on the main body 1. Two hook plates 4 are hinged to the main body 1 at opposite positions through a rotating shaft 7, so that the two hook plates can rotate by taking the rotating shaft as a center, and the lower ends of the two hook plates are separated/closed. The driving device 3 is configured to drive the two hook plates 4 to turn in opposite directions for separation, specifically, the driving device 3 is an up-down driving device, and a driving body 5 is installed at a telescopic end of the driving device 3. The inner sides of the two hook plates 4 are provided with guide plates 6, the lower sides of the two guide plates 6 are respectively formed with first inclined surfaces 601, the two first inclined surfaces 601 form a structure with a wide lower part and a narrow upper part, the cross section of the lower end of the driving body is large in size, and the lower end of the driving body 5 is clamped between the two first inclined surfaces 601 to prevent the hook plates from freely rotating. When the driving body moves upwards, the lower end of the driving body presses the two first inclined surfaces to two sides to separate the two hook plates, and when the driving body moves downwards, the two hook plates are closed under the action of gravity. Holes 401 are formed in the two hook plates 4, flange plates 201 are fixed to two sides of the hanging nail 2, and downward protrusions 203 are arranged on the edges of the flange plates 201. The hanging nail 2 is installed on the upper portion of the building component in advance, the axis of the flange plate 201 is horizontal and is on the same plane with the symmetry axis of the hook plates 4 on the two sides, when the two hook plates 4 are closed, the two flange plates 201 are respectively inserted into the two holes 401, the hook of the component is achieved, and the protrusion on the lower side of the flange plate can prevent the hook plates from sliding outwards to cause unhooking.

Two proximity switch 8 is all installed in the outside of hook plate 4, and proximity switch is located the position that the protruding of hanging nail flange plate was located after the couple was accomplished, can judge the hook plate and hang nail flange plate whether contact, judges promptly whether to get in touch well, can give alarm information when two side hook plates do not get in touch unsuccessfully or unilateral couple is unsuccessful, can prevent unexpected unhook and virtual string.

Second inclined planes 202 are formed on the upper sides of the flange plates 201 on the two sides of the hanging nail 2, and the two second inclined planes 202 form a structure with a narrow upper part and a wide lower part. In the hooking stage, when the main body integrally descends, the two second inclined planes guide the two hook plates to be relatively opened under the action of self weight, and in the process of continuing descending, the flange plates of the hanging nails gradually enter the holes of the hook plates, and the hook plates on the two sides are close to each other. The lower sides of the flange plates 201 on the two sides of the hanging nail 2 are respectively provided with a protrusion 203, when the flange plates of the hanging nail are provided with a hole for the protrusion part to completely enter the hook plate, the hook main body is integrally lifted, and the lower edge of the hole is contacted with the lower part of the flange plate to complete the hook. When the hook is unhooked, the main body moves downwards, and then the driving body is controlled to move upwards, so that the hook plates on the two sides are relatively opened and separated from the flange plates of the hanging nails.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
