Description

Technical Field

[0001] The utility model relates to the technical field of hangers for surface treatment, in particular to a U-bolt contact-free production hanger. Background Art

[0002] After the screw is surface treated, a protective layer is formed on its surface. The most common method is galvanizing. Galvanizing is to immerse the bolt in a solution containing zinc ions for treatment. The surface treatment can effectively improve the rust resistance.

[0003] U-bolts are much larger than ordinary screws. When multiple U-bolts are stacked together for surface treatment, the stacked parts don't fully contact the treatment liquid, resulting in poor surface treatment. Therefore, U-bolts can be hung on a bracket (equivalent to the frame in this application), but due to the special shape of the U-bolts, they cannot be properly fixed.

[0004] For example, the patent application number "202120704579.5" proposes a U-bolt contactless production hanger, which, when in use, adjusts the distance between the movable beam 13 and the support beam by adjusting the locking screw 11, so that the high-temperature rubber pad 10 on the surface of the movable beam 13 and the support beam can clamp the threads at both ends of the U-bolt. This clamping method is suitable for clamping the two ends of a tight U-bolt, but when there are multiple tight U-bolts, the clamping operation cannot be performed because the movable beam 13 and the support beam are rigid beams. After a U-bolt is placed between the movable beam 13 and the support beam, the placed U-bolt must be clamped, otherwise it will fall, making it impossible to clamp and fix multiple bolts, and the operation process is extremely inconvenient. To this end, we propose a U-bolt contactless production hanger. Utility Model Content

[0005] In response to the deficiency that existing hangers cannot effectively support U-bolts, the utility model provides a U-bolt contact-free production hanger, which has the advantages of clamping both ends of the bolt through a clamp and then hanging the hanger on the frame to fix it, solving the problems raised in the above background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A U-bolt contact-free production hanger is designed, comprising a strip-shaped support portion, a hook provided in the middle of the surface of the strip-shaped support portion, and clamps provided at both ends of the strip-shaped support portion;

[0008] The distance between the two clamps matches the positions of the two ends of the U-bolt, and the two clamps are respectively clamped at the threads at the two ends of the U-bolt.

[0009] Optionally, the clamp includes two mounting seats arranged opposite to each other, one end of each mounting seat is connected to a clamping plate, and the ends of the two clamping plates are each provided with an opening;

[0010] The two mounting bases are rotatably connected at opposite sides, and an elastic support member is provided between the two. Under the support of the elastic support member, the two clamping plates are closed together so that the two openings clamp the ends of the U-bolts.

[0011] One end of one of the mounting seats close to the strip-shaped support portion is connected to the end of the strip-shaped support portion, and one end of the other mounting seat close to the strip-shaped support portion is connected to a pressing handle.

[0012] Optionally, the pressing handle is bent and arranged at the side surface of the strip-shaped support portion, and movable gaps are provided between the mounting seat, the strip-shaped support portion and the side surface of the strip-shaped support portion respectively.

[0013] Optionally, a U-shaped seat is installed on the opposite side of the two mounting seats, the two U-shaped seats are arranged opposite to each other and are connected by a rotating shaft, the elastic support member is a torsion spring arranged in the middle of the rotating shaft, and the free ends of the torsion spring are in elastic contact with the mounting seats respectively.

[0014] Optionally, a certain gap is provided between the two clamping plates, and arc-shaped plates are respectively provided in the openings. The inner walls of the arc-shaped plates are provided with a number of evenly distributed conical protrusions, and the tips of the conical protrusions are all facing the surface of the U-bolt.

[0015] Optionally, the strip-shaped support portion, the hook and the clamp are all conductors.

[0016] Optionally, the hook is hung on a frame, which includes a main rod with multiple layers of outwardly extending arms on its surface, and each arm is provided with multiple spaced hanging slots, and the hook is then hung in the hanging slot.

[0017] Optionally, a hook is provided on the top of the main rod.

[0018] Compared with the prior art, when using the present invention, the two ends of the U-shaped bolts to be processed can be clamped in the clamps at both ends of the strip support part. The operation is simple and easy to use. Then the hook can be hung on the frame used for surface treatment, so that multiple U-shaped bolts will not be stacked together during surface treatment, thereby affecting the treatment quality.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 The utility model provides a technical solution: a U-bolt contact-free production hanger, comprising a strip support portion 1, a hook 2 is provided in the middle of the surface of the strip support portion 1, and clamps are provided at both ends of the strip support portion 1, and the distance between the two clamps matches the position of the two ends of the U-bolt 12.

[0026] like Figure 4 As shown, in the actual application process, the frame used for surface treatment includes a main rod 15, and the surface of the main rod 15 is provided with multiple layers of outwardly extending support arms 13, and each support arm is provided with multiple spaced hanging grooves 14, and then the hook 2 is hung in the hanging groove 14. The top of the main rod 15 is provided with a hook, which is used to connect the lifting equipment. Driven by the lifting equipment, the frame is immersed in the treatment liquid. The frame, the strip support part 1, the hook 2 and the clamp are all conductors and can be energized.

[0027] like Figure 1 and Figure 2 As shown, the specific structure of the clamp includes two opposing mounting blocks 10, each connected to a clamping plate 9 at one end. The ends of both clamping plates are provided with openings 8, the size of which matches the diameter of the U-bolt 12. The two mounting blocks 10 are rotatably connected together on opposite sides, with an elastic support member provided between them. Under the support of the elastic support member, the two clamping plates 9 are closed together, so that the two openings 8 clamp the ends of the U-bolt 12, that is, the two ends of the U-bolt 12 are respectively clamped within the openings 8.

[0028] One end of one of the mounting seats 10 close to the strip-shaped support portion 1 is connected to the end of the strip-shaped support portion 1 , and one end of the other mounting seat 10 close to the strip-shaped support portion 1 is connected to a pressing handle 11 .

[0029] Specifically, the hangers proposed in this application should be multiple. In actual use, the two ends of the U-shaped bolt that needs surface treatment are placed in the clamp, that is, the operator can pinch the pressure handle 11 with one hand, open the splint 9 connected to it, place the end of the bolt in the opening, and then release the pressure handle 11.

[0030] Because the opening 8 is clamped at the threads at both ends of the screw, it has good anti-slip properties and will not allow the screw to fall out of the opening;

[0031] The present application has also made further improvements to the opening 8, further improving the stability of the bolt end. A certain gap is provided between the two clamping plates 9, and the gap is used for the movement of the two openings 8. Arc plates 7 are respectively provided in the openings 8. The height of the arc plates 7 should be less than the thread length of the two ends of the U-bolt 12. A number of evenly distributed conical protrusions 6 are provided on the inner wall of the arc plates 7. The conical protrusions 6 are pointed. The curved shape of the arc plates 7 is consistent with the curved shape of the screw surface, and the tips of the conical protrusions 6 are all facing the surface of the U-bolt 12. Therefore, when the opening is stuck on the screw end, the arc plates 7 are surrounded by the surface of the screw end, allowing the ends of the conical protrusions 6 to be stuck on the thread surface. This can prevent the screw from falling off from the opening and increase the stability of the screw.

[0032] The most important thing is that the tip of the conical protrusion 6 is stuck on the thread surface, and the conical protrusion 6 is in point contact with the screw surface, which greatly reduces the contact area between the arc plate 7 and the screw. At the same time, the conical protrusion 6 can create a gap between the arc plate and the screw surface. When it is immersed in the treatment liquid, the treatment liquid can also flow into the thread surface and treat the thread surface. The tip of the conical protrusion 6 is in point contact with the screw surface, and the contact part can be ignored, so the thread part is also treated.

[0033] In order to better press the handle 11, as Figure 1 As shown, the pressing handle 11 is bent and arranged on the side of the strip support part 1, and there is a movable gap between the mounting seat 10 and the strip support part 1 and the side of the strip support part 1 respectively. Therefore, when in use, the four fingers of the hand hold the strip support part 1, and the thumb presses the pressing handle 11 to open the clamp.

[0034] Furthermore, the specific rotational relationship between the two mounting seats 10 is that a U-shaped seat 4 is installed on the opposite side of the two mounting seats 10, the two U-shaped seats 4 are arranged opposite to each other and are connected by a rotating shaft 5, and the elastic support member is a torsion spring 3 arranged in the middle of the rotating shaft 5. The free ends of the torsion spring 3 are elastically in contact with the mounting seats 10 respectively. Driven by the elastic force of the torsion spring 3, the two splints 9 are always in a closed state.

[0035] In summary, the hanger proposed in this application can keep each U-bolt independent, allowing the rod part of the U-bolt to be placed in the treatment liquid without contact, allowing the treatment liquid to fully contact the surface of the rod of the U-bolt, and the treatment liquid can also flow into the thread to treat the surface of the thread.
