Description

Technical Field

[0001] The utility model belongs to the technical field of hot-dip galvanizing, in particular to a hot-dip galvanizing hanger device. Background Art

[0002] For the hot-dip galvanizing process of long and heavy steel pipes, the current common practice is to manually connect multiple steel pipes together, use hooks to vertically lift multiple steel pipes, and then multiple steel pipes are arranged from top to bottom, with hooks at the top, and the steel pipes are moved and transported into the treatment pool. After galvanizing, the multiple steel pipes are vertically lifted out, and finally the connected multiple steel pipes are manually disassembled into single steel pipes. The whole process requires a lot of manpower, high labor costs, and the connection and disassembly process of the steel pipe will inevitably affect its hot-dip galvanizing effect, resulting in more defects in the final product and poor coating uniformity. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a hot-dip galvanizing hanger device, which can independently control the hanger units at both ends of the workpiece to achieve the tilted extension of the workpiece out of the liquid pool, so that the coating of the workpiece is more uniform.

[0004] The utility model solves the technical problem by adopting the following technical solution: a hot-dip galvanizing hanger device, comprising at least two sets of hanger units arranged relatively to each other, wherein the hanger units comprise supporting members for mounting workpieces, and limiting members located above the supporting members for pressing the workpieces; the two ends of the workpieces are respectively arranged on the hanger units at both sides, and the lifting and lowering of the hanger units are independently controlled so that the workpieces can be tilted or horizontally extended out of the liquid pool.

[0005] In the utility model, at least two groups of hanger units located at both ends of the workpiece can be used to achieve the workpiece to be tilted out of the liquid pool, so that the liquid on the surface of the workpiece can be quickly discharged, avoiding excessive local accumulation of liquid due to the excessive length of the workpiece and affecting the uniformity of the coating; multiple workpieces can be placed side by side on the supporting member at intervals, and multiple workpieces can be processed simultaneously with the same processing time, thereby improving processing efficiency and high processing consistency; the limit member and the supporting member cooperate to achieve stable clamping of the workpiece, avoiding random displacement of the workpiece, and ensuring a good processing effect.

[0006] Furthermore, the support member is provided with a plurality of positioning grooves at intervals, and the end of the workpiece has a lower claw portion that can cooperate with the positioning groove. The positioning groove and the lower claw portion cooperate to prevent the workpiece from lateral separation from the support member, and also prevent the workpiece from shifting relative to the support member when the workpiece is tilted.

[0007] Furthermore, the end of the workpiece has an upper claw portion that can cooperate with the limiting member.

[0008] Furthermore, the positioning groove is an inclined V-shaped notch groove, the end of the workpiece is placed in the V-shaped notch groove, and the side wall of the V-shaped notch groove is tapered. The V-shaped notch groove design reduces the contact area between the workpiece and the positioning groove, which facilitates the rapid downward discharge of the material liquid of the workpiece, and the tapered side wall of the V-shaped notch groove further reduces the contact area between the positioning groove and the joint, and also facilitates the rapid discharge of the material liquid on the joint, so that the coating on the surface of the workpiece is more uniform.

[0009] Furthermore, the upper claw and the lower claw both have a guide surface, and the bottom of the upper claw forms an inclined guide surface. The design of the guide surface and the inclined guide surface facilitates the rapid discharge of the liquid, avoids the accumulation of the liquid on the workpiece, and ensures the uniformity of the coating.

[0010] Furthermore, the hanger unit includes a main frame, and a movable frame connected to the main frame, the supporting member is arranged at the bottom of the main frame, the limiting member is arranged at the bottom of the movable frame, and the movable frame can be vertically lifted relative to the main frame. The main frame and the movable frame are designed to be light in weight, and the overall matching structure is stable and effective. When the movable frame moves up and down relative to the main frame, it can drive all the limiting members to move up and down synchronously, which is convenient for clamping or releasing the workpiece.

[0011] Furthermore, the top of the movable frame is provided with a counterweight, and the bottom of the movable frame is provided with a fork, which can be abutted against the outside to lift the movable frame upward relative to the main frame. The design of the fork facilitates the outside to lift the movable frame upward, so that the workpiece can be separated from the hanger unit.

[0012] Furthermore, a blocking block is provided on the top of the main frame body, which can abut against the counterweight block, and the height of the blocking block is equivalent to the height of the clamped part of the workpiece. The blocking block limits the movable frame body to a set position to prevent it from excessively moving downward, and prevents it from causing damage to the workpiece while ensuring a stable clamping of the workpiece.

[0013] Furthermore, the limiter comprises a plurality of supporting parts connected to the bottom of the movable frame, and a limiter rod connected to the plurality of supporting parts, and the side wall of the limiter rod is cut to form an inclined surface. The limiter rod is connected to the supporting part to increase the structural stability of the limiter, and the side wall of the limiter rod is cut to form an inclined surface to reduce the contact area between the limiter rod and the workpiece, thereby ensuring the uniformity of the coating of the workpiece.

[0014] Furthermore, the workpiece is in the shape of a long rod.

[0015] The beneficial effects of the utility model are as follows: the workpiece is tilted out of the liquid pool, and the liquid on its surface can be quickly discharged, avoiding local accumulation of liquid and affecting the uniformity of the coating; the contact area between the workpiece and the hanger unit is small, the liquid on the workpiece can be quickly discharged downward, and the coating uniformity on the surface of the workpiece is good; multiple workpieces are placed side by side and at intervals on the supporting member to achieve synchronous processing, which improves the processing efficiency and has high processing consistency; the limit member and the supporting member cooperate to achieve stable clamping of the workpiece, avoid arbitrary displacement of the workpiece, and ensure good processing effect; the cooperation of the main frame and the movable frame facilitates the clamping and unclamping of the workpiece.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] like Figure 1 , Figure 2 As shown, a hot-dip galvanizing hanger device includes at least two sets of hanger units 1 arranged opposite to each other, the hanger unit 1 includes a supporting member 3 for erecting a workpiece 2, and a limit member 4 located above the supporting member 3 and used to press the workpiece 2, the two ends of the workpiece 2 are respectively arranged on the hanger units 1 on both sides, and the lifting and lowering of the hanger units 1 on both sides are independently controlled, so that the workpiece 2 can be tilted or horizontally extended out of the galvanizing pool liquid pool, where the liquid pool can be a galvanizing pool or a pickling pool, and there is no specific limitation. The above-mentioned independent lifting and lowering control of the hanger units 1 on both sides means that the hanger units 1 on both sides do not move up or down synchronously, so that the hanger units 1 on both sides can be at different heights, which is convenient for the workpiece 2 to be tilted out or tilted into the liquid pool.

[0029] In this embodiment, there are two hanger units 1, which are respectively located at the two ends of the workpiece 2. Of course, in other embodiments, there may be multiple hanger units 1, in which one end of the workpiece 2 has one, two or more hanger units 1 at the same time.

[0030] like Fig. 9 , Fig.10 As shown, the workpiece 2 is in the shape of a long rod with a joint 20 at its end. The joint 20 has a lower claw portion 21 and an upper claw portion 22. The lower claw portion 21 has a guide surface 211, and the upper claw portion 22 has a guide surface 221 and an inclined guide surface 222 located at the bottom thereof.

[0031] like Figure 3 , Figure 5-Figure 8As shown, the support member 3 is provided with a plurality of positioning grooves 31 at intervals. The positioning grooves 31 are inclined V-shaped notch grooves. The end joint 20 of the workpiece 2 is placed in the V-shaped notch groove. Specifically, the lower claw portion 21 of the workpiece 2 is adaptively placed in the V-shaped notch groove, so that the workpiece 2 will not be moved laterally (in the form of a vertical axis). Figure 4 The direction shown in the figure is used as an example to detach from the supporting member 3, and also to avoid the workpiece 2 from shifting relative to the supporting member 3 when the workpiece 2 is tilted. At the same time, multiple workpieces 2 are ensured to be arranged at intervals to avoid interference between adjacent workpieces 2 and ensure the uniformity of the coating on the workpiece 2.

[0032] The positioning groove 31 is a V-shaped notch groove. When the workpiece 2 is mounted in the positioning groove 31, the contact area between the two is very small, especially there is no large contact area at the bottom, so that the material liquid on the workpiece 2 can be quickly discharged downward through the lower claw 21 and the V-shaped side wall of the V-shaped notch groove, and the material liquid will not accumulate at the bottom of the positioning groove 31, resulting in uneven coating of the workpiece 2. Under this premise, in order to further reduce the contact area between the positioning groove 31 and the joint 20, and at the same time facilitate the rapid discharge of the material liquid on the joint 20, the side wall of the V-shaped notch groove is tapered. Specifically, the thickness of the side wall of the V-shaped notch groove decreases from the direction close to the joint 20 to the outside, so that the material liquid can flow outward quickly along the inclined side wall of the V-shaped notch groove.

[0033] like Figure 7 As shown, the hanger unit 1 includes a main frame 11 and a movable frame 12 connected to the main frame 11, the supporting member 3 is arranged at the bottom of the main frame 11, the limiting member 4 is arranged at the bottom of the movable frame 12, and the movable frame 12 can be vertically raised and lowered relative to the main frame 11.

[0034] In this embodiment, the main frame 11 is a square frame structure, and the supporting member 3 is connected to the bottom closed end of the main frame 11; the movable frame 12 is also a square frame structure, and the limiting member 4 is connected to the bottom closed end of the movable frame 12. The top of the movable frame 12 is provided with a counterweight 13, or the top of the movable frame 12 itself is a counterweight, and the top of the main frame 11 is provided with a blocking block 111. In a natural state, due to the action of the counterweight 13, the top of the movable frame 12 is against the blocking block 111. Since the height of the blocking block 111 is equivalent to the height or thickness of the clamped part of the workpiece 2, the limiting member 4 and the supporting member 3 cooperate to just clamp the joint 20 of the workpiece 2 up and down.

[0035] A fork portion (not shown in the figure) is provided at the bottom of the movable frame 12, which extends vertically downward from the bottom ends of both sides of the movable frame 12, that is, its lower end exceeds the movable frame 12 and the main frame 11. The fork portion can be against the outside world, so that under the support of the outside world, the movable frame 12 can overcome the counterweight block 13 and lift upward relative to the main frame 11, so that the limit member 4 releases the pressure on the joint 20 of the workpiece 2, thereby facilitating the workpiece 2 to separate from the hanger unit 1.

[0036] like Figure 5 , Figure 6 As shown, the limiting member 4 includes a plurality of supporting parts 41 connected to the bottom of the movable frame 12, and a limiting rod 42 connected to the plurality of supporting parts 41. The limiting rod 42 may be one, which connects the plurality of supporting parts 41 together to increase the overall stability. Of course, the limiting rod 42 may be multiple, which are respectively fixedly connected to the plurality of supporting parts 41. In order to reduce the mating contact area between the limiting rod 42 and the claw part 22 on the joint 20, the side wall of the limiting rod 42 may be cut to form an inclined surface 421, that is, the thickness of the limiting rod 42 decreases upward from the direction close to the joint 20.

[0037] The working process of the utility model is to use the outside world and the fork to cooperate to lift the movable frame 12 upward, place multiple workpieces 2 on the supporting member 3, specifically, the lower claw portion 21 of the joint 20 is placed on the positioning groove 31, and the lifting effect on the movable frame 12 is released. The movable frame 12 automatically moves downward relative to the main frame 11, so that the limit member 4 is pressed on the inclined drainage surface 222 of the upper claw portion 22, and the operation at the other end of the workpiece 2 is the same as above; drive the two groups of hanger units 1 to move downward, and at the initial position, the two groups of hanger units 1 are at different heights, so that the workpiece 2 tilts into the liquid pool, or the two groups of hanger units 1 have the same initial height, but the downward movement speed is different, so that the workpiece 2 tilts into Entering the liquid pool, of course, the workpiece 2 can also be in a horizontal state when entering the liquid pool; after the workpiece 2 has completed the treatment in the liquid pool, for example, after completing the hot-dip galvanizing treatment in the galvanizing pool, the two sets of hanger units 1 cooperate to tilt the workpiece 2 out of the liquid pool (of course, horizontal or nearly horizontal tilting out of the liquid pool is not excluded). At this time, due to the tilt of the workpiece 2, the liquid on its surface can be quickly discharged downward, and the liquid in the joint 20 can be quickly discharged along the inclined drainage surface 222 and the guide surface 221 of the upper claw 22, and the guide surface 211 of the lower claw 21, so that the entire surface of the workpiece 2 can achieve the purpose of uniform coating, and will not cause the local coating of the workpiece 2 to be thick, and the coating effect is good.

[0038] The above specific implementation modes are used to explain the present invention rather than to limit the present invention.
