Detailed implementation manners

[0017] To make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, in the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0019] The present invention provides as Figure 1-13A feeding device for a section steel galvanizing sling, as shown, includes an L-shaped placing table 1. One side of the L-shaped placing table 1 is equipped with a feeding device which can drive the section steel to move horizontally. A plurality of first rotating rollers 2 are installed on the L-shaped placing table 1. A placing mechanism and a positioning mechanism are installed on the L-shaped placing table 1. The placing mechanism includes a lifting table 3 located above the L-shaped placing table 1. A lifting frame 4 is installed on the L-shaped placing table 1, and the lifting frame 4 can drive the lifting table 3 to move up and down. On both sides of the upper surface of the lifting table 3, limiting frames 5 are installed, and a galvanizing sling 6 is placed in the limiting frames 5. The positioning mechanism includes a positioning plate 7 located on one side above the lifting table 3. A moving frame 8 is installed on the L-shaped placing table 1. When the lifting table 3 drives the limiting frames 5 to move up and down, the moving frame 8 can be driven to drive the positioning plate 7 to move left and right. Above the limiting frames 5, there is an L-shaped limiting rod 9, and the L-shaped limiting rod 9 is installed on the L-shaped placing table 1 through a connecting frame 10.

[0020] The process of feeding the section steel by this device is as follows: Place the galvanizing sling 6 in the limiting frames 5, place the L-shaped limiting rod 9 in the connecting frame 10, and make the L-shaped limiting rod 9 located above the galvanizing sling 6. Drive the lifting table 3, the limiting frames 5, and the galvanizing sling 6 to move up and down through the lifting frame 4, and make the placing rod at the uppermost part of the galvanizing sling 6 located below the first rotating rollers 2. When driving the section steel to move horizontally through the feeding device, the section steel can pass through the inner side of the galvanizing sling 6 and above the uppermost placing rod. At this time, the section steel can be supported by the first rotating rollers 2. When one end of the section steel abuts against the positioning plate 7, the section steel can stop moving and be positioned. Then drive the lifting table 3, the limiting frames 5, and the galvanizing sling 6 to move upward through the lifting frame 4. The section steel can be lifted by the placing rod, and the placing rod of the second layer can be moved to below the first rotating rollers 2. When the limiting frames 5 move upward, the positioning plate 7 can be driven to move through the moving frame 8. Then when feeding the section steel, the second section steel can be positioned. Due to the different positions of the two positioning plates 7, the section steels can be distributed in a staggered manner. And so on. When the limiting frames 5 and the galvanizing sling 6 move upward, it is convenient to feed the section steel and distribute it in a staggered manner. When the section steel moves upward, the holes on the section steel can be sleeved outside the L-shaped limiting rod 9. When the galvanizing sling 6 is full of section steels, remove the galvanizing sling 6 and the L-shaped limiting rod 9, and then it is convenient to galvanize the section steels. Then the staff places a new galvanizing sling 6 on the limiting frames 5 again and repeats the above process to feed the section steel again.

The positions of the lifting rods 60 correspond to the placing rods of the galvanized sling 6 one by one. When the support platform 23 moves upward, the lifting rods 60 can first contact the profiled steel. At this time, the profiled steel is not placed on the placing rod of the galvanized sling 6, which can keep the profiled steel stable, prevent the profiled steel from tilting and shaking, and further facilitate the L-shaped limiting rod 9 to penetrate into the hole on the profiled steel. After the galvanized sling 6 needs to be removed, the galvanized sling 6 is lifted by the hook. The support platform 23 does not move. Further, the profiled steel can be lifted by the placing rod on the galvanized sling 6, and the L-shaped limiting rod 9 can prevent the profiled steel from shaking.
