Abstract
Description
Technical Field
[0001] The utility model relates to the field of floor decking processing, in particular to a feeding device for producing steel bar truss floor decking. Background Art
[0002] Rebar truss floor decking is a floor decking structure formed by resistance welding formed rebar trusses to galvanized steel plates. Currently, during the production process of rebar truss floor decking, the rebar trusses need to be lifted to the predetermined position on the galvanized steel plates using electromagnetic lifts, and then transported horizontally to the welding station for point-by-point welding, which can efficiently realize the production operation of rebar truss floor decking.
[0003] When it comes to loading steel trusses, traditional electromagnetic lifters mostly use ropes to suspend the steel trusses. After the steel trusses are lowered to the predetermined position on the galvanized steel plate, the ropes are removed, and the operation process is relatively cumbersome. Although existing electromagnetic lifters can also lift heavy steel structures, due to the triangular cross-section of the steel trusses, the special structure of the existing electromagnetic lifting lifts can only act on the upper chord steel bars at the top of the triangle of the steel trusses. During the magnetic attraction process, it is very easy to cause the steel trusses to tip over and be dislocated, and then the side surface of the steel trusses composed of the upper chord steel bars and a group of lower chord steel bars are adsorbed on the bottom of the electromagnetic lifting lift, which causes inconvenience to the placement of the steel trusses on the galvanized steel plate. Utility Model Content

The upper ends of the two groups of second flip frames extend between the two groups of first flip frames and are hinged on a group of horizontal connecting shafts, and the two ends of the connecting shafts are connected to the carrier plate located above, so that a V-shaped opening that can accommodate the steel truss is formed between the two groups of second flip frames, and the two groups of second flip frames are provided with a magnetic suction component that can absorb the steel truss.
[0008] Preferably, each end of the connecting shaft has a group of threaded pins, and the lower end of the threaded pin is provided with a sleeve that is sleeved on the connecting shaft; the upper ends of the two groups of threaded pins pass through the carrier plate, and the upper end of the carrier plate is provided with a nut that is sleeved on the two groups of threaded pins, so that the size of the V-shaped opening can be adjusted by moving the connecting shaft up and down.
[0009] Preferably, the first flip frame is a frame with a hollowed-out middle portion, wherein the hollowed-out portion is used to avoid the magnetic attraction component when the V-shaped opening is adjusted.
[0010] Preferably, the upper end of the carrier plate is horizontally slidably mounted in the base body so that the position of the lifting assembly is adjustable.
[0011] Preferably, a horizontal guide shaft is provided at the lower end of the base body, and the upper end of the carrier plate is slidably sleeved on the guide shaft.

[0025] Reference Figure 2The two ends of the second turning frame 52 are respectively hinged on the lower end of the two first turning frames 51 and the upper end of the two second turning frames 52 extends between the two first turning frames 51. The upper ends of the two second turning frames 52 are hinged on a set of horizontal connecting shafts 54; the rotation axes at both ends of the first turning frame 51 and the axes at both ends of the second turning frame 52 are parallel to the aforementioned connecting shafts 54, and the two ends of the connecting shafts 54 are connected to the carrier plate 50 located above. Therefore, a V-shaped opening that can accommodate the steel truss 3 is formed between the two sets of second turning frames 52.
