Description

Technical Field

[0001] The utility model relates to the field of metal material processing and manufacturing, in particular to a special lifting device for a metal material processing suction cup. Background Art

[0002] Metal workpieces, especially large-sized and large-size metal plates (aluminum plates, copper plates, steel plates, etc.), need to be placed on the processing surface of the machining center for fixing during machining. Unlike ordinary small workpieces, metal plates cannot be clamped and fixed by ordinary fixtures due to their large area. Instead, they are fixed by suction cups placed on the processing table of the machining center, and the metal plates are sucked and fixed by the negative pressure air grooves on the suction cups. The size of the suction cups must be larger than the size of the metal plates, and they are hoisted and installed on the processing table before processing the metal plates. The usual suction cup device is provided with several horizontally arranged threaded holes on the side, and the lifting rings are screwed into the threaded holes. The lifting rings are fixedly connected to the wire rope of the overhead crane, thereby lifting and moving the suction cup platform.

[0003] However, the currently used lifting method has the following hidden dangers. Since the lifting ring screw is in a horizontal direction, the lifting ring bears the upward pulling force of the wire rope, so the screw mainly bears the shear force. However, the ideal state of the screw is usually to be subjected to tension. When subjected to shear force, the strength is greatly reduced. Therefore, when lifting and processing the suction cup, there are great hidden dangers in operational safety. When the lifting ring is subjected to excessive shear force exceeding the limit, the lifting ring screw will break, and the entire suction cup will fall down, causing a safety accident. Summary of the invention

[0004] The utility model provides a special lifting device for metal material processing suction cups, which has an improved design for lifting the processing suction cups, can prevent the breakage of the lifting rings during the lifting of the processing suction cups, prevent oblique pulling and oblique lifting, and optimize the force mode of the lifting rings; the same lifting device can also adapt to the lifting of processing suction cups of different sizes, and the adaptation process is simple and convenient.

[0005] In order to achieve the above objectives, the technical solution of the utility model is as follows:

[0006] A special lifting device for a metal material processing suction cup, wherein protrusions are respectively arranged at the four corners of the processing suction cup, and lifting rings are arranged on the upper end faces of the protrusions; the positions of the lifting rings match the positions of the lifting hooks of the lifting device, and the lifting hooks are fixed on the crossbeams of the lifting device, and the crossbeams and the longitudinal beams constitute the frame of the lifting device, and triangular trusses are respectively arranged at both ends of the frame, and the triangular trusses are connected by hanging plates, and two hanging holes are arranged on the hanging plates, and the hanging holes are connected to the hooks of a double-hook overhead travelling crane.

[0007] The utility model changes the current situation of the lifting ring being directly installed on the side wall of the processing suction cup for oblique lifting. The lifting ring is directly threaded and screwed into the screw hole of the protruding part, changing the shear force of the lifting ring into the tensile force of the thread. The lifting ring is not directly connected by a wire rope, but connected to the double-hook overhead crane through a special lifting device. The advantages are: the distance between the two lifting hooks of the double-hook overhead crane is fixed, and the distance between the lifting holes on the hanging plate is also fixed and matches the distance between the double-hook overhead crane; when the double-hook overhead crane lifts the lifting device, the hook hooks the lifting ring vertically, and there is no oblique lifting, and the stress state between the various components is stable.

[0008] The middle beam of the triangular truss is fixedly connected to both ends of the hanging plate. The triangular truss transmits the lifting force of the hanging plate to the lifting frame. The whole lifting device has good rigidity and stability.

[0009] A crossbar is arranged on the upper part of the hook, a hook is welded to the lower end surface of the middle part of the crossbar, and both ends of the crossbar are mounted on the crossbeam and provided with a plurality of screw holes, and the heads of the fixing bolts pass through the through holes and are screwed to the screw holes of the crossbeam. Since a plurality of screw holes are evenly distributed on the crossbeam, the hook can be fixed at a suitable position according to the length of the suction cups of different sizes, thereby improving the application range of the lifting device.

[0010] There are several beams, and the hook crossbar can be installed on any two adjacent beams. The hook can be installed on two suitable adjacent beams according to the width of the suction cups of different sizes, thereby improving the application range of the sling.

[0011] The lower end surface of the protrusion is provided with reinforcing ribs connected to the side wall of the processing suction cup. The triangular reinforcing ribs can improve the force bearing capacity of the protrusion and prevent the protrusion from breaking with the edge of the suction cup.

[0012] Advantages of utility models:

[0013] 1. The utility model changes the current situation of the lifting ring being sheared during horizontal lifting, and changes the lifting ring vertically screwed into the screw hole to a tensile state, thereby reducing the risk of the lifting ring breaking; in addition, a special lifting device is used so that the lifting ring is only subjected to vertical tension, further improving the stress state of the lifting ring, ultimately greatly reducing the probability of the suction cup falling, and improving production safety.

[0014] 2. The utility model sling can also adapt to the lifting of suction cups of different sizes, and the hook position can be adjusted within a certain range in the horizontal X and Y directions, which greatly improves the adaptability of the special sling.

[0015] 3. The special lifting device of the utility model has a stable structure of a triangular prism as a whole, has good overall rigidity, and is not easy to deform and twist. BRIEF DESCRIPTION OF THE DRAWINGS
