Description

Technical Field

[0001] The present invention relates to the technical field of spring hanger coating processing, and particularly to an integrated device for manufacturing and transporting spring hangers and its working method. Background Art

[0002] Spring hangers are designed based on the principle of moment balance. Within the specified load displacement range, the load moment and the spring moment always remain balanced. Therefore, when the pipes and equipment supported by constant hangers undergo displacement, a constant supporting force can be obtained, without imposing additional stress on the pipes and equipment. Constant hangers are generally used in places where displacement stress needs to be reduced, such as the main body of power station boilers, the suspended parts of steam, water, and flue gas pipes and burners in power plants, as well as petrochemical equipment and other places where displacement stress needs to be reduced. Among them, small spring hangers need to be coated with wear-resistant coatings on their surfaces during production to ensure that they are not corroded and rusted in various environments and to increase their service life. The coating effect of existing spring hanger coating production devices is average, and the steps of coating, transporting, and air-drying are cumbersome and inefficient, and some improvements are needed.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0027] Please refer to Figure 1-7 , the present invention provides a technical solution: a manufacturing and transportation integrated device for spring hangers and its working method, including a box body 1, a first motor 5 is fixedly connected to one side of the box body 1, a first rotating rod 6 is arranged on one side of the first motor 5, a third rotating rod 20 is rotatably connected through the inside of the box body 1, a second belt pulley assembly 13 is arranged on the surfaces of the first rotating rod 6 and the third rotating rod 20, trays 14 are fixedly connected to one ends of the first rotating rod 6 and the third rotating rod 20, a second motor 9 is fixedly connected to one side of the box body 1, a second rotating rod 12 is arranged on one side of the second motor 9, a fan blade 21 is arranged on the surface of the second rotating rod 12, a spring hanger 16 is installed on one side of the tray 14, a baffle 17 is arranged in the hole groove on the surface of the spring hanger 16, a pair of first fixed seats 10 are fixedly connected to one side of the box body 1, a worm 11 is rotatably connected inside the first fixed seat 10, a first belt pulley assembly 8 is arranged on the surfaces of the worm 11 and the first rotating rod 6, a fourth rotating rod 22 is rotatably connected through the box body 1, a worm gear 7 is fixedly connected to one end of the fourth rotating rod 22, the worm gear 7 is meshed with the worm 11, a circular plate 23 is fixedly connected to one end of the fourth rotating rod 22, a first fixed rod 24 is fixedly connected to one end of the circular plate 23, a reciprocating ring 25 is arranged on the surface of the first fixed rod 24, guide rods 26 are fixedly connected to both sides of the reciprocating ring 25, a pair of corresponding guide seats 27 are fixedly connected to one side of the box body 1, the guide rods 26 are slidably connected inside the guide seats 27, connecting plates 28 are fixedly connected to both ends of the guide rods 26, a nozzle 30 is arranged on one side of the connecting plate 28, an infusion assembly is arranged between the connecting plate 28 and one side of the box body 1, and a transportation assembly is arranged on one side of the box body 1.

[0028] Specifically, the surface hole groove of the spring support hanger 16 is blocked by a baffle 17 to prevent the internal spring assembly from being affected during coating. At this time, the motor 5 is started, and the motor 5 drives the rotating rod 6 set on one side to rotate, and the rotating rod 6 drives the pulley assembly 8 set on the surface to operate, and the pulley assembly 8 drives the internal worm 11 to rotate, and the worm 11 drives the meshing worm wheel 7 on one side to rotate, and the rotating rod 22 and the circular plate 23 fixed on one side of the worm wheel 7 rotate accordingly, and the circular plate 23 drives the fixed rod 24 fixed on the surface to move in a circular trajectory, and the fixed rod 24 moves the surface reciprocating ring 25. Due to the reciprocating ring Guide rods 26 are fixed on both sides of 25, and the guide rods 26 are slidably connected with the guide seat 27, so the reciprocating ring 25 and the guide rods 26 make linear reciprocating sliding displacement, which drives the connecting plate 28 to make linear reciprocating displacement in the vertical direction. At this time, the nozzle 30 cooperates with the infusion component to coat the outer ring of the rotating spring support hanger 16. As the spring support hanger 16 rotates, the worm gear assembly slows down so that the coating assembly and the spring support hanger 16 can complete the offset coating, and finally the entire outer ring is coated. After the coating is completed, the motor 5 is stopped, and then the spring support hanger 16 is transported to the transport assembly. Figure 2 In the tray on the left, the left tray 14 and the rotating rod three 20 can be directly driven to rotate by the motor assembly. Since the motor is a prior art, it is not drawn in the figure. This is the preferred solution one. The preferred solution two can set a pulley assembly two 13 on the surface of the rotating rod three 20 and the rotating rod one 6, so that the rotating rod one 6 rotates and drives the rotating rod three 20 to rotate, so that the spring support hanger 16 and the fan blade 21 are aligned. At this time, the new spring support hanger 16 to be coated is installed in the right tray 14. At this time, the motor one 5 is started again, and the motor two 9 is started. The motor two 9 drives the fan blade 21 for air drying. The positions of the two trays 14 should be kept at a certain distance to prevent the coating work from affecting the air drying work, and vice versa. The motor one 5 drives the right tray 14 to rotate and drives the spring support hanger 16 to rotate, and at the same time makes the coating assembly make a linear reciprocating sliding displacement in the vertical direction to coat the entire outer ring of the spring support hanger 16, and the work efficiency is high.

[0029] The infusion assembly includes a liquid storage tank 18, which is fixedly connected to a side of the box body 1, a liquid storage tank 29 is arranged on one side of the connecting plate 28, and an infusion tube 19 is arranged between the liquid storage tank 18 and the liquid storage tank 29. The infusion tube 19 is of suitable length and soft texture.

[0030] Specifically, the coating work needs to process multiple spring hangers 16, which requires a large amount of coating liquid. If the liquid storage tank is completely installed on the surface of the connecting plate 28, the weight will be increased and the motor load will be increased. It is divided into two parts, and the main body is installed on the surface of the box body 1. The coating liquid is transported to the nozzle 30 for processing through the infusion pipe 19 and the branch liquid storage tank 29, which can effectively avoid this situation.

[0031] The transport component includes a chute 4 which is arranged on the upper surface of the box body 1. Inside the chute 4, a first cylinder assembly 31 is fixedly connected. On one side of the first cylinder assembly 31, there is a sliding seat 32. On one side of the sliding seat 32, there is a second cylinder assembly 33. On one side of the second cylinder assembly 33, a second connecting plate 34 is fixedly connected. On one side of the second connecting plate 34, a number of support rods are fixedly connected. One end of the support rod is fixedly connected with a bottom plate 35. On one side of the second connecting plate 34, a third cylinder assembly 36 is fixedly connected. On one side of the third cylinder assembly 36, there is a third connecting plate 37. On both sides of the bottom plate 35, a number of symmetric guide plates 39 are fixedly connected. At both ends of the third connecting plate 37, there are sliding plates 38. Inside the guide plates 39, there are sliding blocks 40 slidingly connected. On the surfaces of the sliding plates 38 and the sliding blocks 40, a number of second fixing rods 41 are fixedly connected. On the surface of the second fixing rods 41, a connecting rod 42 is rotatably connected. On the surface of the second fixing rods 41 fixed inside the sliding blocks 40, a pair of clamping jaws 43 are fixedly connected. On one side of the clamping jaws 43, there is a stabilizing rod 44.

[0032] Specifically, when it is necessary to transport the spring hanger 16, first, the position of the sliding seat 32 is adjusted through the first cylinder assembly 31. After the position is correct, the second cylinder assembly 33 is used to push the second connecting plate 34 to drive the bottom plate 35 to descend. At this time, the gap between the clamping jaws 43 can pass through the base on the spring hanger 16. Now, to contract and fix the clamping jaws 43, the third cylinder assembly 36 is started. With the bottom plate 35 stationary, it drives the third connecting plate 37 and the sliding plates 38 fixed on both sides to move downward. The sliding plates 38 drive the second fixing rods 41 fixed on the surface to move downward. The second fixing rods 41 are also fixed on the surface of the sliding blocks 40. The corresponding second fixing rods 41 on the surfaces of the sliding plates 38 and the sliding blocks 40 are rotatably connected by the connecting rod 42. Now, the sliding plates 38 and the second fixing rods 41 fixed on their surfaces slide downward to pull the connecting rod 42 to move downward, causing the respective sliding blocks to approach and slide, driving the corresponding clamping jaws 43 to approach each other to complete the fixation, clamping the upper base of the spring hanger 16. The spring hanger 16 processed here is a small spring hanger, which can adapt to this transportation method and will not be unable to be clamped and transported due to excessive weight.

[0033] On one side of the box body 1, there is a box door 2, and on the surface of the box door 2, there is a handle 3.

[0034] Specifically, the box door 2 can be closed during coating processing to prevent liquid from splashing to the outside, and the handle 3 facilitates opening and closing the box door 2.

[0035] On one side of the tray 14, there is a protective ring 15.

[0036] Specifically, the protective ring 15 is used to ensure that the spring hanger 16 can be successfully installed in the center of the tray 14, preventing position deviation and affecting coating.

[0037] On one side of the box body 1, there is a cover plate 45, and the tray 14 is in clearance fit with the cover plate 45.

[0038] Specifically, the cover plate 45 can cover the inner lower wall of the box body 1 to prevent the coating from affecting the operation of components such as the first rotating rod 6. The tray 14 is in clearance fit with the cover plate 45 without affecting the rotation of the tray 14. A small amount of coating liquid seeping in from the gap is cleaned regularly, and the impact is not significant.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows mutual communication; it can be directly connected, or it can be the internal communication between two components or the interaction relationship between two components.
