Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 to 6, the present invention provides a hanging tool device with changeable angle for hanging a workpiece 5. In the present embodiment, the angle-changeable hanger device is used for hot dip galvanizing, but is not limited thereto.

The angle-changeable hanger device comprises a connecting piece 3 and a balancing stand 6. The link 3 is intended to be mounted to a suspended conveyor line for movement. The balance frame 6 is connected to the connecting member 3. The balance frame 6 is used for suspending the workpiece 5. The balancing stand 6 can drive the workpiece 5 to turn over to change the angle.

In the illustrated embodiment, the connecting member 3 is an H-beam. Two gimbals 6 are suspended from each link 3. It will be appreciated that in other embodiments, the link 3 may suspend one or more gimbals 6.

The connecting piece 3 is connected to the electric hoist 1 of the suspension conveying line. In the illustrated embodiment, the connecting members 3 are connected to an electric hoist 1 at positions near both ends. The angle-changeable hanger device also comprises a connecting rod 2. The length of the connecting rod 2 is matched with the positions of two lifting points of the connecting piece 3. The connecting rod 2 is used for connecting two hoisting points, so that the two electric hoists 1 keep synchronous.

The balancing stand 6 comprises a frame 6-1, a rotating shaft 6-2 and two fixing rods 6-4. The frame 6-1 is rotatably connected to the link 3 by a rotation shaft 6-2. The rotating shaft 6-2 is deviated from the center of gravity of the frame 6-1, so that the balance frame 6 is obliquely suspended from the connecting member 3 with a first end higher than a second end. The two fixing rods 6-4 are arranged at two ends of the frame 6-1. The fixing rod 6-4 can be clamped on the upper surface of the connecting piece 3 after extending out, and the balancing stand 6 is in an inclined state.

In one embodiment, the frame 6-1 is further provided with two position-limiting members. The two limiting parts are respectively positioned at two ends of the frame 6-1 and are arranged at intervals along the vertical direction with the corresponding fixed rods 6-4. The two limit pieces are stopped by the lower surface of the connecting piece 3 to limit the rotation angle of the balancing stand 6. When the limiting piece is contacted with the lower surface of the connecting piece 3, the fixing rod 6-4 at the same end is extended out and then clamped on the upper surface of the connecting piece 3, so that the balancing stand 6 is fixed.

The balance frame 6 connects the plurality of chains 4. The plurality of chains 4 are respectively arranged on two sides of the rotating shaft 6-2. A plurality of chains 4 are used to connect both sides of the workpiece 5 for suspension. The balancing stand 6 drives the suspended workpiece 5 to rotate synchronously with the workpiece, so that the workpiece 5 and the balancing stand 6 keep the same inclination state.

The balancing stand 6 is formed by welding two steel structures, and the two steel structures are connected into a whole by angle steel at two ends.

In one embodiment, a weight block is further fixed on the balancing stand 6, and the weight block is used for adjusting the rotation speed of the balancing stand 6.

The utility model also provides a use method of the hanging tool device of convertible angle, include:

s1: the balancing frame 6 is arranged on the connecting piece 3 through the rotating shaft 6-2, and the heavier end (the second end) of the balancing frame 6 is lifted and fixed through the corresponding fixing rod 6-4.

After fixation, the second end of the balancing stand 6 is higher than the first end.

Since the balance frame 6 does not suspend the workpiece 5 yet, the rotation thereof is easy.

The heavier end of the balancing stand 6 is manually lifted until the limiting part contacts the lower surface of the connecting piece 3. Then, the corresponding fixing rod 6-4 is pushed out, so that the fixing rod 6-4 is clamped on the upper surface of the connecting piece 3.

S2: the workpiece 5 is suspended from the balance frame 6.

The balance frame 6 is lifted to a certain height through the electric hoist 1 to facilitate material hanging, and after the material hanging is completed, the balance frame 6 is lifted to a transportation height through the electric hoist 1.

S3: and moving the workpiece 5 into the plating solution for plating through a hanger device with a changeable angle.

Because the second end of the balancing stand 6 is higher than the first end, when the workpiece 5 moves into the plating solution, the part of the workpiece 5 close to the first end firstly enters the plating solution, and the part close to the second end then enters the plating solution.

Two gib heads of electric block 1 descend simultaneously, slowly immerse work piece 5 in zinc liquid level, and this in-process keeps connecting piece 3 to be the horizontality, can have the inclination of small width, but need avoid connecting piece 3 and zinc petticoat pipe, zinc pot platform collision to interfere.

S4: the fixing rod 6-4 is moved to release the balancing stand 6, so that the balancing stand 6 rotates under the action of gravity until the lighter end (first end) is lifted and fixed by the corresponding fixing rod 6-4.

Since the workpiece 5 is positioned in the plating solution, the resistance to moving the fixing bar 6-4 to release the balancing stand 6 is small, which facilitates the operation. The balancing stand 6 rotates under the action of gravity, the heavier side slowly sinks, and the lighter side slowly floats, and no additional power is needed in the process. Until the limiting part contacts the lower surface of the connecting piece 3, the lower surface is fixed by a corresponding fixing rod 6-4. Because only the workpiece is below the zinc liquid level and the balancing stand 6 is above the plating solution, workers can see the workpiece by naked eyes in the rotating process, and even if some emergency occurs, the workers can take related measures at any time, so that the safety and the reliability of the film coating process are ensured.

S5: and (5) finishing coating, and removing the workpiece 5 from the plating solution.

Since the balance frame 6 has been turned over, its first end is higher than the second end. When the workpiece 5 is moved out, the plating solution is firstly discharged from the part of the workpiece 5 close to the first end, and the plating solution is discharged from the part of the workpiece 5 close to the second end.

In addition, those skilled in the art should realize that the above embodiments are illustrative only and not limiting to the present application, and that suitable changes and modifications to the above embodiments are within the scope of the disclosure of the present application as long as they are within the true spirit and scope of the present application.
