Description

Technical Field

[0001] The invention relates to the technical field of hot-dip galvanizing, in particular to a hot-dip galvanizing device for electric iron accessories. Background Art

[0002] Iron accessories generally refer to the iron parts on concrete poles and their connections, such as various clamps, nails, fork beams, cross beams, pull rods, wire rods, etc. Iron accessories have a wide range of applications and are easy to use. They are widely used in: communications or electricity, line construction and installation, such as laying optical cables, laying electrical cables, etc., used in conjunction with steel strands, used for ground pulling or making suspension line end knots, used to fix steel strands, lining rings are used in conjunction with ground stones, ground anchor rods, pull wires, and suspension wires.

[0003] Iron accessories need to be hot-dip galvanized during the processing to achieve the purpose of corrosion protection. For some smaller iron accessories, the small iron accessories are generally placed inside the holding tube (the holding tube is hung on the overhead crane), and then the holding tube is placed in the pickling tank. After rust removal in the pickling tank, it is immersed in molten zinc liquid at about 500°C to make a zinc layer adhere to the surface of the iron accessories. After galvanizing, the zinc needs to be thrown off. After the zinc throwing is completed, the holding tube needs to be removed and the plated parts are poured into the water tank for post-processing. If automated equipment is used to complete the above process, at least a set of tube grabbing device, tube unloading device and dumping device is required. The equipment is highly complex and needs to be improved. Summary of the invention

[0004] In order to solve the problems mentioned in the background technology, the object of the present invention is to provide a hot-dip galvanizing device for electric iron accessories.

[0005] In order to achieve the above object, the technical solution of the present invention is:

[0006] A hot-dip galvanizing device for electric iron accessories comprises a galvanizing tank and a crane, the crane can pass over the galvanizing tank, a first lifting mechanism is installed on the crane, a first lifting seat is connected to the lifting end of the first lifting mechanism, a second lifting mechanism is installed on the first lifting seat, a second lifting seat is connected to the lifting end of the second lifting mechanism, a rotary motor is longitudinally installed on the second lifting seat, a conical orifice plate is arranged below the rotary motor, the cone tip of the orifice plate is coaxially connected to the main shaft of the rotary motor through a connecting shaft, a collar is horizontally arranged below the first lifting seat, the collar is connected to the first lifting seat through a plurality of connecting rods, a rotating drum is rotatably installed in the collar, the rotating drum is concentrically arranged with the orifice plate, and the second lifting mechanism can drive the orifice plate to be clamped at the bottom of the rotating drum or make the orifice plate leave the rotating drum.

[0007] Further, a splash-proof cylinder is longitudinally arranged below the overhead crane. The splash-proof cylinder is fixedly connected to the overhead crane through a plurality of connecting columns. The first lifting mechanism can drive the rotating cylinder and the orifice plate to enter or extend out of the splash-proof cylinder.

[0008] Further, the inner diameter of the rotating cylinder is the same as the outer diameter of the orifice plate. A plurality of through holes are evenly distributed on the circumferential surface of the rotating cylinder. A plurality of clamping protrusions are connected to the bottom edge of the orifice plate. Corresponding to the plurality of clamping protrusions, notches are arranged at the bottom edge of the rotating cylinder. When the second lifting mechanism drives the orifice plate to rise, the plurality of clamping protrusions can be respectively clamped in the plurality of notches.

[0009] The beneficial effects of the present invention are as follows: The working process of the present invention is as follows. When the orifice plate and the rotating cylinder are docked, iron accessories can be placed. When the overhead crane moves above the galvanizing tank, the first lifting mechanism drives the rotating cylinder and the orifice plate to move downward into the galvanizing tank, so that the iron accessories can be galvanized. After galvanizing is completed, the first lifting mechanism drives the rotating cylinder and the orifice plate to leave the galvanizing tank. The rotary motor drives the orifice plate to rotate, further driving the rotating cylinder to rotate to realize zinc flinging. After zinc flinging is completed, the overhead crane is driven to move above the water tank, and the second lifting mechanism is used to drive the orifice plate to move downward to separate it from the rotating cylinder, and the iron accessories will slide into the water tank under the action of gravity. A set of devices integrates the functions of galvanizing, zinc flinging, and feeding, eliminating the need to set up a grab cylinder device, a discharging cylinder device, and a dumping device, greatly simplifying the equipment requirements of the production line.
