[0002] Hot-dip galvanizing, also known as hot-dip galvanizing, is a metal surface treatment technology that forms a layer of zinc and / or zinc-iron alloy coating on the surface of standard parts (such as bolts) by immersing them in molten zinc liquid. This treatment not only enhances the corrosion resistance of standard parts, but also increases their service life.

[0003] The structure of the currently commonly used zinc removal equipment is as follows: Figure 1 As shown, it includes a frame 1, a clutch 2, a motor 3, a barrel throwing assembly 4, a cylinder 5, a cover plate 6 and a zinc blocking barrel 15; the clutch 2 and the motor 3 are arranged inside the frame 1, the motor 3 drives the clutch 2 through a coupling, and the clutch 2 drives the barrel throwing assembly 4 through a bevel gear to start or stop zinc throwing. The barrel throwing assembly 4 includes an outer ring 41, a bearing 42, an inner ring 43, a throwing frame 44, and a barrel 45. The inner ring 43 and the throwing frame 44, and the throwing frame 44 and the barrel 45 are all fixedly connected. The clutch 2 drives the inner ring 43, the throwing frame 44, and the barrel 45 to rotate at a high speed through the bevel gear, and the zinc-immersed standard parts in the barrel 45 are thrown out at a high speed. The excess zinc liquid on the surface of the standard parts is thrown out through the holes on the barrel 45, and the zinc blocking barrel 15 can block the zinc liquid thrown out from the side wall 451 of the barrel 45. The air cylinder 5 drives the cover plate 6 to cover the top of the barrel 45 , which can prevent the zinc liquid from splashing out from the top opening 452 of the barrel 45 or the standard parts from flying out from the top opening 452 .

[0004] However, the zinc retaining cylinder 15 is fixed on the frame 1. After the zinc is thrown out, the zinc liquid and zinc slag attached to the zinc retaining cylinder 15 are not easy to clean. Utility Model Content

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A zinc-swinging device for facilitating cleaning of a zinc-blocking cover comprises a frame, a power assembly fixed inside the frame, a bucket-swinging assembly connected to the output end of the power assembly, and a zinc-blocking cover for blocking splashing of zinc liquid; the bucket-swinging assembly comprises a swinging frame connected to the output end of the power assembly, and a barrel fixedly sleeved with the swinging frame, the zinc-blocking cover is sleeved on the outside of the barrel, the zinc-blocking cover is slidably arranged on the frame, the zinc-blocking cover comprises a first split body and a second split body, the first split body and the second split body both perform linear reciprocating motion along the length direction of the frame, and the first split body and the second split body cover the side wall and the top opening of the barrel when they slide relative to each other until they abut against each other.

[0008] As a limitation of the present utility model: the first split body and the second split body have the same structure, the first split body includes a top plate and side plates fixedly connected, the side plates are used to cover the side walls of the barrel, and the top plate is used to cover the top opening of the barrel, and the shape formed when the first split body and the second split body are abutted is adapted to the shape of the barrel.

[0009] As a further limitation of the present invention: two sets of driving components are arranged on the frame, and the two sets of driving components respectively drive the first split body and the second split body to slide in opposite or reverse directions.

[0010] As a further limitation of the present invention: the driving assembly includes a cylinder fixed on the frame, the telescopic direction of the cylinder is arranged along the length direction of the frame, and the output end of the cylinder is connected to the first split body or the second split body.

[0011] As another limitation of the present invention: the power assembly includes a motor and a clutch, the output end of the motor is connected to the input end of the clutch, the output end of the clutch is connected to the swing frame, and the rotation axis of the clutch is parallel to the central axis of the barrel.

[0012] As a further definition of the utility model: a first bevel gear and a second bevel gear of meshing transmission are arranged between the motor and the clutch, the intersection angle between the axes of the first bevel gear and the second bevel gear is 90°, the output end of the motor is fixedly connected to the first bevel gear, the second bevel gear is fixedly connected to the input end of the clutch, and the rotation axis of the motor is perpendicular to the rotation axis of the clutch.

[0013] As a further limitation of the present utility model: a transmission shaft is connected to the output end of the motor, the axial direction of the transmission shaft is arranged along the length direction of the frame, and one end of the transmission shaft away from the motor is fixedly connected to the first bevel gear.

[0014] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0015] (1) The utility model is an improvement made to the existing zinc throwing equipment. The improvement lies in that the zinc shielding cover covering the outside of the barrel is set as a split structure, and the zinc shielding cover includes a first split body and a second split body, and the first split body and the second split body are slidably arranged on the frame and perform linear reciprocating motion along the length direction of the frame; during the zinc throwing operation, the first split body and the second split body are relatively slid, and when the first split body and the second split body are abutted, they can completely cover the side wall and the top opening of the barrel; after the zinc throwing is completed, the first split body and the second split body are slid away from each other to facilitate cleaning of the zinc liquid and zinc slag attached to the zinc shielding cover;

[0016] (2) The motor and clutch in the prior art are relatively close. Since the motor cannot withstand the high temperature of the zinc pot, the zinc-spinning device cannot be placed above the zinc pot during use. Therefore, the spun zinc liquid cannot be reused. In the utility model, a transmission shaft and a first bevel gear and a second bevel gear for meshing transmission are arranged between the motor and the clutch. There is a certain distance between the motor and the clutch. The device can be placed above the zinc pot.

The output end of the clutch is directly connected to the swing frame, which has a fast response speed and higher transmission efficiency, thereby improving the zinc swing efficiency.

[0018] In summary, the utility model is convenient for cleaning the zinc shield, can realize the reuse of the zinc liquid thrown out, and can improve the transmission efficiency and the zinc throwing efficiency; the utility model is suitable for the hot-dip galvanizing industry and is used for drying the excess zinc liquid on the surface of standard parts.

[0031] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and do not constitute a limitation to the present invention.

[0032] The directional terms or positional relationships such as "left", "right", "front", and "back" described in the embodiments are based on the drawings in the specification of the utility model. Figure 2 , 3 The orientation relationship is only for the convenience of describing the present invention and simplifying the description. It does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the content protected by the present invention.

[0033] The length direction mentioned in this embodiment refers to the left and right directions.

[0034] like Figure 2 to Figure 6 As shown, this embodiment includes a frame 1, a power assembly fixed inside the frame 1, a bucket-swinging assembly 4 connected to the output end of the power assembly, and a zinc-blocking cover 7 for blocking zinc liquid from splashing. The zinc-blocking cover 7 includes a first split body 71 and a second split body 72. The first split body 71 and the second split body 72 both make linear reciprocating motion along the length direction of the frame 1. The first split body 71 and the second split body 72 slide relative to each other until they abut against each other so as to cover the side wall 451 and the top opening 452 of the barrel 45, and then the zinc-swinging operation begins. After the zinc-swinging is completed, the first split body 71 and the second split body 72 are slid in opposite directions, and the first split body 71 and the second split body 72 are separated from the barrel 45, so as to clean the zinc liquid and zinc slag attached to the zinc-blocking cover 7.

[0035] 1. Bucket swinging assembly 4;

[0036] like Figure 2 , 5 As shown, the barrel assembly 4 includes a swing frame 44 connected to the output end of the power assembly, and a barrel 45 fixedly sleeved with the swing frame 44. A plurality of holes are provided on the side wall 451 of the barrel 45 so that the zinc liquid can be thrown out from the holes when the zinc is thrown. Since the structures of the swing frame 44 and the barrel 45 are the same as those in the prior art, they will not be described in detail in this embodiment.

[0037] 2. Zinc shield 7;

[0038] like Figure 2 As shown, the zinc shield 7 is sleeved on the outside of the barrel 45 and slidably arranged on the frame 1. Specifically, the zinc shield 7 includes a first split body 71 and a second split body 72. The first split body 71 and the second split body 72 have the same structure. The first split body 71 is taken as an example for description: Figure 3 , 5 As shown, the first split body 71 includes a top plate 73 and a side plate 74 that are fixedly connected. The side plate 74 is in an arc shape and is used to cover the side wall 451 of the barrel 45; the top plate 73 is in a semicircular shape and is used to cover the top opening 452 of the barrel 45. The first split body 71 and the second split body 72 can both slide in the left and right directions. When the first split body 71 slides to the right and the second split body 72 slides to the left until the two are in contact, the shape formed by the first split body 71 and the second split body 72 (i.e., the overall shape of the zinc shield 7) is adapted to the shape of the barrel 45, see Figure 2 Here, the matching means that the overall shape of the zinc shield 7 is similar to the barrel 45, the two side plates 74 are connected to form a conical cylindrical structure, and the two semicircular top plates 73 are connected to form a full circle. Of course, the zinc shield 7 can also be a cylinder, a cube or other structures.

[0039] 3. Drive components;

[0040] like Figure 2 , 3 As shown, two groups of driving components are arranged on the frame 1, one group is arranged on the left side of the frame 1, and is used to drive the first split body 71 to slide in the left and right directions, and the other group is arranged on the right side of the frame 1, and is used to drive the second split body 72 to slide in the left and right directions, so as to achieve the purpose of sliding the first split body 71 and the second split body 72 in relative or opposite directions.

[0041] The structures of the two drive components are the same. Take the drive component on the left side of rack 1 as an example:

[0042] like Figure 3-6As shown, the drive assembly includes a cylinder 5, which is fixed on the frame 1 through a bracket 12, and the telescopic direction of the piston rod 8 in the cylinder 5 is set along the length direction of the frame 1. A connecting plate 13 is fixed on the side plate 74 in the first split body 71, and a movable plate 14 is fixed on the end of the connecting plate 13 close to the piston rod 8. The output end of the cylinder 5 (i.e., the right end of the piston rod 8) is fixedly connected to the movable plate 14, and the piston rod 8 drives the first split body 71 to slide to the left or right. The cover plate in the prior art is driven by the cylinder to rotate upward and open. Since the cover plate is heavy, its weight is completely borne by the cylinder, which makes the cylinder easy to be damaged and has a short service life. In this embodiment, the piston rod 8 in the cylinder 5 drives the first split body 71 to move linearly, and the weight of the first split body 71 is borne by the frame 1, which increases the service life of the cylinder 5.

[0043] In order to ensure the sliding stability of the first split body 71, two guide posts 16 extending in the left and right directions are fixed on the bracket 12. Figure 5 , 6 , two guide posts 16 are arranged at intervals. Four limit blocks 17 are fixedly arranged at the bottom of the moving plate 14, two of which are arranged at the front and rear sides of the moving plate 14, the two limit blocks 17 at the front side are jointly sleeved on the front guide post 16, and the two limit blocks 17 at the rear side are jointly sleeved on the rear guide post 16. This structure ensures the linearity of the sliding of the moving plate 14 and the first split body 71, and prevents the front and rear swings from affecting the sliding stability. The connection between the drive assembly on the right side of the frame 1 and the second split body 72 is the same as described above, and will not be repeated here.

[0044] It should be noted that the driving assembly in this embodiment can also be replaced with other structures in the prior art, as long as it can drive the first sub-body 71 and the second sub-body 72 to slide left and right. For example, a structure in which a motor and a lead screw are matched is adopted, and a lead screw is fixed between the two guide posts 16 on the bracket 12. The lead screw axially extends in the left and right directions. Correspondingly, a sliding block is fixed at the middle position of the bottom of the moving plate 14. The sliding block is threadedly sleeved on the lead screw. The motor drives the lead screw to rotate, and the moving plate 14 has a tendency to rotate with the lead screw. However, the matching of the guide post 16 and the limit block 17 restricts the moving plate 14 from rotating. At this time, under the thread matching, the moving plate 14 can only move left and right along the lead screw, so that the first sub-body 71 can only slide left and right. Since the method of realizing linear motion by a motor and a lead screw is a prior art, it will not be elaborated here.

[0045] 4. Power components;

[0046] like Figure 3As shown, the power assembly includes a motor 3 and a clutch 2, the clutch 2 adopts an electromagnetic clutch of the prior art, the output end of the motor 3 is connected to the input end of the clutch 2, and the output end of the clutch 2 is connected to the swing frame 44. Specifically, a first bevel gear 9 and a second bevel gear 10 of meshing transmission are arranged between the motor 3 and the clutch 2, the axis angle between the first bevel gear 9 and the second bevel gear 10 is 90°, the output end of the motor 3 is fixedly connected to the first bevel gear 9, the second bevel gear 10 is fixedly connected to the input end of the clutch 2, the rotation axis of the clutch 2 is parallel to the central axis of the barrel 45, and the rotation axis of the motor 3 is perpendicular to the rotation axis of the clutch 2. In this structure, the clutch 2 is directly connected to the swing frame 44, eliminating the installation of the inner ring, bearing, and outer ring in the prior art, improving the reaction speed, and the transmission efficiency and zinc swing efficiency are higher.

[0047] Further, the output end of the motor 3 is connected with a transmission shaft 11, and the axial direction of the transmission shaft 11 is arranged along the length direction of the frame 1, and the transmission shaft 11 is fixedly arranged at the output end of the motor 3, and the first bevel gear 9 is fixedly arranged at one end (i.e., the left end) of the transmission shaft 11 away from the motor 3, and the motor 3 works to drive the transmission shaft 11 and the first bevel gear 9 to rotate, thereby rotating the second bevel gear 10 and the clutch 2, and the throwing frame 44 works. The motor 3 and the clutch 2 in the prior art are relatively close and have the same axis of rotation, but because the motor 3 cannot withstand the high temperature of the zinc pot, the zinc throwing device cannot be placed above the zinc pot, so the zinc liquid thrown out cannot be reused. In the present embodiment, a transmission shaft 11, a first bevel gear 9, and a second bevel gear 10 are arranged between the motor 3 and the clutch 2, and there is a certain distance between the motor 3 and the clutch 2, and the device can be placed above the zinc pot, after placement, the barrel 45 and the clutch 2 correspond to the zinc pot, and the motor 3 is located outside the zinc pot, and the zinc liquid thrown out can flow back into the zinc pot, realizing the reuse of zinc liquid, and solving the problem of difficulty in zinc liquid recovery.

[0048] 5. Rack 1;

[0049] like Figure 2 , 5 As shown, in this embodiment, the frame 1 is a rectangular parallelepiped frame, and the frame 1 is composed of thick-walled square tubes, which can withstand the gravity and centrifugal force of the barrel-spinning assembly 4 without deformation.

[0050] When using this embodiment, place this embodiment above the zinc pot, with the barrel 45 and the clutch 2 corresponding to the zinc pot, operate the cylinder 5 to separate the first split body 71 and the second split body 72, put the barrel 45 into the swing frame 44, start the cylinder 5 to make the first split body 71 and the second split body 72 move relative to each other until they abut, see Figure 2 , start the motor 3, the clutch 2 works, the throwing frame 44 rotates to start the zinc throwing, and after the zinc throwing is completed, the throwing frame 44 stops rotating, and the cylinder 5 is operated to move the first split body 71 to the left and the second split body 72 to the right. Figure 5As shown, after the first sub-body 71 and the second sub-body 72 are away from the barrel 45, the zinc liquid and zinc slag attached to the zinc shield 7 (i.e., the first sub-body 71 and the second sub-body 72) can be cleaned; since the device is placed above the zinc pot, the zinc liquid thrown out by the barrel 45 will fall back into the zinc pot and can be reused.

[0051] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiment, those skilled in the art can still modify the technical solutions recorded in the above embodiment or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
