Description

Technical Field

[0001] This utility model relates to the field of steel pipe galvanizing technology, and in particular to a steel pipe galvanizing device that can assist in hoisting. Background Technology

[0002] Galvanizing is a surface treatment technology that coats the surface of metals, alloys, or other materials with a layer of zinc for aesthetic purposes, rust prevention, and other functions. According to different galvanizing methods, it can be divided into hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life, and is widely used in steel pipe anti-corrosion processes to form galvanized steel pipes. When galvanizing steel pipes, a steel pipe galvanizing device is required.

[0003] Chinese Patent Publication No. CN 220503147 U discloses a novel steel pipe galvanizing device, including a galvanizing box. An adjustment mechanism is installed on the back side of the galvanizing box, and the adjustment mechanism includes an adjustment frame. A servo motor is fixedly connected to the right side of the adjustment frame, and an adjustment screw is fixedly connected to the output end of the servo motor. An adjustment sleeve is threaded onto the surface of the adjustment screw. This novel steel pipe galvanizing device uses a servo motor to drive the adjustment screw to rotate. The rotation of the adjustment screw causes the adjustment sleeve to move, which in turn moves a connecting rod. The movement of the connecting rod moves a drying box, which in turn moves a drive motor and a heating element. This allows for the drying of galvanized steel pipes, solving the problem that existing galvanizing methods leave zinc residue on the surface of the steel pipe, which is then statically air-dried, resulting in low galvanizing efficiency and affecting the galvanizing effect.

[0004] The existing technical solutions mentioned above have the following shortcomings: Although the technical solutions can fix the steel pipes during use, their applicability is limited. There will be dead corners in the galvanizing of the steel pipes covered by the positioning rings, which has certain room for optimization. Therefore, it is necessary to design a steel pipe galvanizing device that can assist in hoisting to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a steel pipe galvanizing device that can assist in hoisting, so as to solve the problem of poor clamping effect mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe galvanizing device that can assist in hoisting, including a hoisting frame and a galvanizing tank, wherein the hoisting frame is fixed to the outside of the galvanizing tank;

[0007] The bottom of the hoisting frame is connected to a movable frame, and electric telescopic rods are fixed to both sides of the top of the movable frame. A hoisting plate is fixed between the output ends of the electric telescopic rods, and a hoisting ring is fixed to both sides of the bottom of the hoisting plate. The bottom of each hoisting ring is connected to an inner support mechanism via a hoisting rope. The inner support mechanism includes a hanging seat, which is connected to the bottom of the hoisting rope. Each hanging seat has an internal groove, and a first threaded rod is rotatably connected inside the internal groove. A movable rod is threaded to the outside of each first threaded rod via a first threaded groove, and a second hinged rod is evenly hinged to the outside of each movable rod. The outside of the hanging seat is evenly connected to the first hinged rod, and an inner support ring is connected to the outside of both the first and second hinged rods. A knob is connected to one side of the hanging seat, and one end of the knob is connected to the first threaded rod.

[0008] Furthermore, guide blocks are fixed on both sides of the movable frame, and horizontal plates are fixed on both sides of the hoisting frame, with guide grooves provided inside the horizontal plates.

[0009] Furthermore, the width of the guide block is matched with the width of the guide groove, and the cross-sections of both the guide block and the guide groove are convex.

[0010] Furthermore, the hoisting frame has an internal receiving groove, and a lead screw is rotatably connected inside the receiving groove. A threaded sleeve is threadedly connected to the outer side of the lead screw, and the bottom end of the threaded sleeve is connected to the top end of the movable frame. A motor is fixed to one side of the hoisting frame by a bracket, and the output shaft of the motor is connected to the lead screw.

[0011] Furthermore, the width of the threaded sleeve matches the width of the receiving groove, and the cross-section of the threaded sleeve is rectangular.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the steel pipe galvanizing device that can assist in hoisting achieves the function of convenient hoisting while being easy to clamp;

[0015] The inner support mechanism is lowered to the front of the galvanizing tank by activating the electric telescopic rod, and then placed on both sides of the steel pipe. Turning the knob drives the first threaded rod to rotate, and under the action of the threaded connection, the moving rod moves outward, driving the first hinge rod, the second hinge rod, and the inner support ring to open outward, so that the inner support ring is tightly fitted to the inner wall of the steel pipe. It is suitable for steel pipes of different inner diameters. It is simple to operate and convenient to use. It not only clamps stably and does not affect the normal galvanizing of the steel pipe, but also facilitates the subsequent hoisting and unloading of steel pipes, enhancing the practicality and flexibility of the device.

[0027] A hoisting frame 1 is fixed to the outside of the galvanizing tank 8, and a movable frame 2 is connected to the bottom of the hoisting frame 1;
