Description

Technical Field

[0001] This utility model belongs to the field of hoisting support technology, specifically a hoisting support for electroplating wells. Background Technology

[0002] In surface treatment industries such as electroplating and anodizing, electroplating wells (or process tanks, treatment tanks) are key equipment used to hold chemical solutions and treat workpieces. These electroplating wells are usually quite deep, and the steel pipes to be electroplated are usually also very long. During the electroplating process, lifting tools are needed to put the steel pipes into or out of the electroplating well. However, existing lifting devices usually put the steel pipes to be electroplated into the electroplating well individually using lifting tools. If multiple steel pipes are put in at the same time, the steel pipes will be close together, resulting in an uneven electroplating layer, which greatly affects product quality. If one steel pipe is used for electroplating at a time, it will greatly affect the production speed, requiring frequent lifting operations, which greatly reduces work efficiency. Therefore, it is necessary to design a lifting support that can lift multiple steel pipes simultaneously and keep each steel pipe separate. Utility Model Content

[0003] To address the above technical problems, this utility model provides a hoisting support that can simultaneously hoist multiple steel pipes and clearly separate each pipe, thus solving the problem that existing hoisting supports cannot hoist multiple steel pipes at the same time.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a hoisting bracket for an electroplating well, comprising an electroplating well, a steel pipe, and a cross, wherein the electroplating well is vertically arranged and its lower part is deeply buried underground, the cross is arranged above the well opening, and symmetrically arranged support legs are fixedly connected to the ground on both sides of the electroplating well. Support bases are fixedly connected to the top of the support legs, and U-shaped frames are fixedly connected to the upper surface of the support bases. The horizontal ends of the cross are detachably connected to the U-shaped frames, and the vertically downward end is inserted into the cross. Inside the electroplating well, V-shaped grooves are vertically arranged on the front and rear sides of the lower end of the cross. A pipe disc is fixedly connected above the V-shaped groove. Through holes are evenly opened on the pipe disc. A pre-tightening clamp is detachably connected to the upper end of the steel pipe. The bottom surface of the pre-tightening clamp is in contact with the upper surface of the pipe disc. An insulating layer, an iron plate, and a negative power supply are detachably connected inside the U-shaped frame. The insulating layer is respectively arranged on both sides of the cross. A pre-tightening screw is threadedly connected to the front of each U-shaped frame. A hanging lug is fixedly connected to the top of the cross.

[0005] Furthermore, the V-shaped grooves are evenly distributed on the front and rear sides of the lower end of the cross, the V-shaped grooves are circular, and each V-shaped groove corresponds to the through hole above, and the outer surface of each steel pipe is in contact with the two sides of the V-shaped groove.

[0006] Furthermore, a negative power terminal is provided between the insulating layer on one side and the cross, and the insulating layer on the other side is provided between the cross and the iron plate. One end of the pre-tightening screw penetrates the front wall of the U-shaped frame and contacts the front of the iron plate.

[0007] Furthermore, the pre-tightening clamp has two pre-tightening holes on one side of its opening, and pre-tightening bolts can be detachably connected to both pre-tightening holes.

[0008] This utility model has the following advantages compared with the prior art:

[0009] 1. This utility model, by setting a cross, facilitates the lifting of multiple steel pipes, reduces the frequency of lifting, and lowers the intensity of manual labor. By setting a pipe-distributing disc, multiple pipes can be evenly distributed on the front and back sides of the cross, preventing the steel pipes from stacking together. By setting a V-shaped groove at the bottom of the cross, the outer surface of the steel pipe can be just stuck in the V-shaped groove, increasing the stability of the steel pipe and preventing the steel pipes from moving during the electroplating process and causing collisions between multiple steel pipes, further improving the electroplating effect.

[0010] 2. This utility model can avoid power short circuits by setting insulation layers on both sides of the cross wall thickness, and transmit power from the cross to the steel pipe for electroplating. By setting an iron plate between the insulation layer and the front wall of the U-shaped frame, it can prevent the pre-tightening screw from directly contacting the insulation layer and causing damage and reducing the insulation effect.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 6 The diagram shows a hoisting support for an electroplating well, comprising an electroplating well 1, steel pipes 2, and a cross 3. The electroplating well 1 is vertically positioned and deeply buried underground. To facilitate hoisting, the cross 3 is positioned above the well opening of the electroplating well 1, with a matching lifting device directly above it for easy lifting and lowering. To support the cross 3, symmetrically arranged support legs 11 are fixedly connected to the ground on both sides of the electroplating well 1. The height of the support legs 11 is higher than the well opening height of the electroplating well 1. To increase the support area, a support base 7 is fixedly connected to the top of the support legs 11. To securely fix the cross 3, a U-shaped frame 6 is fixedly connected to the upper surface of the support base 7. The horizontal ends of the cross 3 are respectively secured to the U-shaped frame 6 by an insulating layer 15, an iron plate 16, and a pre-tightening screw 8. The vertically downward end of the cross 3 is inserted into the electroplating well 1. To prevent the steel pipes 2 from partially contacting each other when inserted into the electroplating well 1, ensuring each steel pipe is independent, two supports are installed at the front and rear ends of the lower end of the cross 3. V-grooves 5 are vertically arranged on the side, and each V-groove 5 is the same size. In order to fix the steel pipe 2 and make it evenly rest against the lower end of the cross 3, a pipe-distributing disc 4 is fixedly connected above the V-grooves 5. To facilitate the passage of the steel pipe 2, through holes 14 are evenly opened on the pipe-distributing disc 4. In order to fix the steel pipe 2 on the pipe-distributing disc 4 and prevent it from sinking into the electroplating well 1, a pre-tightening clamp 12 is provided at the upper end of the steel pipe 2. The pre-tightening clamp 12 is sleeved on the outer surface of the steel pipe 2, and is tightened by tightening the pre-tightening screw. Bolt 13 enables detachable connection. The bottom surface of pre-tightening clamp 12 contacts the upper surface of the pipe disc 4. The U-shaped frame 6 is detachably connected to the insulating layer 15, iron plate 16, and negative power supply 9. In order to complete electroplating and avoid power short circuit, the insulating layer 15 is respectively set on the front and rear sides of the cross 3 located inside the U-shaped frame 6. In order to clamp the cross 3, a pre-tightening screw 8 is threadedly connected to the front of each U-shaped frame 6. In order to facilitate cooperation with the lifting device, a hanging lug 10 is fixedly connected to the top of the cross 3.

[0020] In order to enable each V-groove 5 to match the upper through hole 14, the V-groove 5 is evenly distributed on the front and rear sides of the lower end of the cross 3. The V-groove 5 is circular, and each V-groove 5 corresponds to the upper through hole 14. The outer surface of each steel pipe 2 is in contact with the two sides of the V-groove 5.

[0021] In order to clamp the cross 3 while preventing the U-shaped frame 6 from conducting electricity, a negative power terminal 9 is provided between the insulating layer 15 on one side and the cross 3, and the insulating layer 15 on the other side is provided between the cross 3 and the iron plate 16. One end of the pre-tightening screw 8 passes through the front wall of the U-shaped frame 6 and contacts the front of the iron plate 16.

[0022] To facilitate the disassembly and assembly of the pre-tightening clamp 12, two pre-tightening holes 17 are provided on the open side of the pre-tightening clamp 12, and pre-tightening bolts 13 can be detachably connected to both pre-tightening holes 17.

[0023] The specific working process of this utility model is as follows:

[0024] In use, first tighten the pre-tightening clamps 12 to one end of each steel pipe 2 to be electroplated, and then pass the other end of the steel pipe 2 through the through hole 14, so that the lower surface of the pre-tightening clamps 12 contacts the upper surface of the pipe distribution disc 4. After one steel pipe 2 is placed in each through hole 14, lift the cross 3 with a lifting device. After lifting the cross 3, the steel pipe 2 will be vertically downward according to its own weight. Align the bottom of the steel pipe 2 with the electroplating well 1. At this time, manual intervention is required to stabilize the steel pipe 2 to prevent it from swinging too much, and to make the outer surface of the steel pipe 2 contact the two sides of the V-groove 5. After the steel pipe 2 is stable, slowly lower it until the two sides of the cross 3 are horizontal. The end is placed into the U-shaped frame 6, and then the insulation layer 15, iron plate 16, and negative power supply 9 are placed in the U-shaped frame 6 respectively. The iron plate 16 is squeezed by screwing in the pre-tightening screw 8 to firmly fix all components in the U-shaped frame 6. At this time, the steel pipe 2 is completely immersed in the electroplating solution in the electroplating well 1 for electroplating. After the electroplating is completed, the pre-tightening screw 8 is loosened, and the electroplated steel pipe 2 is removed by lifting the cross 3 with a lifting device. In this embodiment, by setting the cross 3 and setting the pipe-distributing disc 4 and the vertical V-shaped groove 5 on the cross 3, multiple steel pipes 2 can be electroplated at one time, and multiple steel pipes are avoided from being stacked together, which reduces the electroplating effect.
