Description

Technical Field

[0001] The utility model relates to the technical field of constant force support and hanger brackets and discloses a highly stable constant force support and hanger bracket. Background Art

[0002] Constant force hangers, also known as constant force spring hangers, are widely used in the fields of petroleum, chemical industry, electric power, etc. For example, inside the pipeline of a power boiler, constant force hangers are used to support pipelines and equipment. Springs, moving plates, cables and rotating plates are arranged inside the constant force hangers. The external pipeline is connected to one end of the rotating plate, and the other end of the rotating plate is connected to the moving plate through a cable. The spring is fixed between the moving plate and the frame and is located outside the cable. The rotating plate rotates under the action of the pipeline load, so that the cable pulls the moving plate to move and squeeze the spring. When the thermal displacement is large, it can support the pipeline to avoid dangerous bending stress and adverse stress transfer in the pipeline system.

[0003] When the existing constant force support and hanger is working, the force applied to the movable plate when it moves under force usually has an upward component, and it is usually subjected to large local stress, which makes it easy for the force-bearing part of the movable plate to wear out. After long-term use, it is easy to loosen due to wear, which can easily lead to instability of the support and hanger. In addition, the constant force support and hanger will absorb and transfer the heat of the boiler pipeline during the contact process with the power generation boiler pipeline, which can easily cause the staff to be scalded when they come into contact with the constant force support and hanger during maintenance, causing physical harm to the staff. Utility Model Content

[0004] The purpose of the utility model is to provide a high-stability constant force support and hanger to address the above-mentioned problems and deficiencies, so as to prevent users from accidentally touching the high-stability constant force support and hanger body and getting burned when repairing and maintaining pipelines, while effectively reducing the wear of the movable plate and effectively improving the stability of the constant force support and hanger.

[0005] A highly stable constant force support and hanger, comprising a mounting tube, the front and rear ends of the left side of the mounting tube are both connected with mounting plates, and a rotating plate is provided between the two mounting plates;

[0006] An intermediate plate and a movable plate are respectively provided in the middle and right sides of the interior of the installation tube, a through hole is opened on the left side of the installation tube, a pull rope passing through the through hole is connected between the left end of the movable plate and the rotating plate, the pull rope passes through the intermediate plate, a spring 1 located outside the pull rope is connected between the intermediate plate and the movable plate, and a spring 2 located outside the pull rope is connected between the intermediate plate and the left side of the inner wall of the installation tube;

[0007] A positioning rod is connected between the two mounting plates and passes through and fixed on the lower end of the rotating plate. A sliding groove is opened in front of the front mounting plate. A rotating column connected to the front of the rotating plate is slidably connected inside the sliding groove. A cooling component is provided on the mounting cylinder.

[0008] Furthermore, the rotating plate is V-shaped, the left end of the rotating plate is rotatably connected to a connecting rod, a fixing frame is installed at the lower end of the connecting rod, and an insulation layer is attached to the inner wall of the fixing frame.

[0009] Furthermore, the cooling assembly includes a button, a fan and a cover, and the button is embedded and installed on the right side of the inner wall of the slide slot.

[0010] Furthermore, the fan is installed above the installation cylinder, the fan faces the rotating plate and the connecting rod, and the button is electrically connected to the fan.

[0011] Furthermore, the upper ends of the two mounting plates are connected with mounting frames, and the cover is connected between the mounting tube and the mounting frame and is located outside the fan.

[0012] The beneficial effects of the utility model are as follows:

[0013] When the high-stability constant force support and hanger is in use, the power pipeline is installed inside the fixed frame. The heat insulation layer inside the fixed frame can block the heat emitted by the power boiler pipeline, thereby reducing the heat transferred from the pipeline to the high-stability constant force support and hanger body. When the pipeline is displaced by thermal vibration, the connecting rod can drive the rotating column to rotate under the action of the load, and the pressing of the button by the rotating column can be released, and the fan starts to work. The wind blown by the fan can cool the rotating plate and the connecting rod, thereby further reducing the heat transferred from the pipeline to the high-stability constant force support and hanger body, avoiding users from accidentally touching the high-stability constant force support and hanger body and getting burned when repairing and maintaining the pipeline;

[0014] When the rotating plate rotates, it drives the pull rope on its right side to move to the left, and at the same time, it can drive the movable plate to move to the left. The stiffness coefficient of spring one is smaller than that of spring two. When the movable plate moves to the left, spring one is compressed and the middle plate is pushed to the left and spring two is compressed at the same time. The tension on the pull rope can be dispersed on spring one, the middle plate, the movable plate and spring two, thereby effectively reducing the wear of the movable plate and effectively improving the stability of the constant force support and hanger.

DETAILED DESCRIPTION

[0019] like Figures 1 to 3 As shown, the present application is a highly stable constant force support and hanger, comprising a mounting tube 1, the front and rear ends of the left side of the mounting tube 1 are connected to mounting plates 8, a rotating plate 12 is provided between the two mounting plates 8, an intermediate plate 3 and a movable plate 4 are provided in the middle and right parts of the interior of the mounting tube 1, respectively, a through hole 7 is opened on the left side of the mounting tube 1, a pull rope 6 passing through the through hole 7 is connected between the left end of the movable plate 4 and the rotating plate 12, the pull rope 6 passes through the intermediate plate 3, a spring 1 2 located outside the pull rope 6 is connected between the intermediate plate 3 and the movable plate 4, and a spring 2 5 located outside the pull rope 6 is connected between the intermediate plate 3 and the left side of the inner wall of the mounting tube 1;

[0020] A positioning rod 13 is connected between the two mounting plates 8 and passes through and is fixed to the lower end of the rotating plate 12. A slide groove 17 is provided in front of the front mounting plate 8. A rotating column 14 connected to the front of the rotating plate 12 is slidably connected inside the slide groove 17. A cooling component is provided on the mounting cylinder 1.

[0021] The rotating plate 12 is V-shaped, and the left end of the rotating plate 12 is rotatably connected to a connecting rod 15, and a fixing frame 16 is installed at the lower end of the connecting rod 15. The inner wall of the fixing frame 16 is attached with a heat insulation layer, and the upper ends of the two mounting plates 8 are connected to mounting frames 9;

[0022] When the high-stability constant-force support and hanger is in use, bolts are passed through the mounting frame 9 to install the entire high-stability constant-force support and hanger at the desired position, and then the power pipeline is installed inside the fixing frame 16. The power pipeline is, for example, a pipeline of a power boiler. The heat insulation layer fitted inside the fixing frame 16 can block the heat emitted by the pipeline of the power boiler. The material of the heat insulation layer can be selected from heat insulation materials such as asbestos, thereby reducing the heat transferred from the pipeline to the main body of the high-stability constant-force support and hanger;

[0023] The cooling assembly includes a button 18, a fan 10 and a cover 11. The button 18 is embedded and installed on the right side of the inner wall of the slide slot 17. The fan 10 is installed above the installation cylinder 1. The fan 10 faces the rotating plate 12 and the connecting rod 15. The button 18 is electrically connected to the fan 10. The cover 11 is connected between the installation cylinder 1 and the mounting frame 9 and is located outside the fan 10.

[0024] When the pipe is displaced by thermal vibration, the connecting rod 15 can drive the rotating plate 12 to rotate around the positioning rod 13 under the action of the load, and the rotating column 14 in front of the rotating plate 12 can rotate with it. Figure 3 As shown, the front end of the rotating column 14 can move to the left along the slide groove 17, and the pressing of the button 18 by the rotating column 14 can be released, and the fan 10 starts to work. Since the fan 10 is facing the rotating plate 12 and the connecting rod 15, the wind blown by the fan 10 can cool the rotating plate 12 and the connecting rod 15, thereby further reducing the heat transferred from the pipeline to the high-stability constant force support and hanger body, and preventing the user from accidentally touching the high-stability constant force support and hanger body when repairing and maintaining the pipeline and getting burned;

[0025] Since the cover 11 is connected between the mounting tube 1 and the mounting frame 9 and is located outside the fan 10, the cover 11 can shield the fan 10 from dust falling from above to a certain extent, thereby preventing the fan 10 from being adhered to a lot of dust and affecting the cooling effect;

[0026] like Figure 1 As shown, the rotating plate 12 rotates while driving the pull rope 6 on its right side to move left. The pull rope 6 is made of steel wire, which is wear-resistant and strong. When the pull rope 6 moves to the left, it can drive the movable plate 4 to move to the left. The stiffness coefficient of spring 1 2 is smaller than that of spring 2 5. When the movable plate 4 moves to the left, spring 1 2 is compressed and the middle plate 3 is pushed to the left and spring 2 5 is compressed at the same time. The tension on the pull rope 6 can be dispersed on spring 1 2, middle plate 3, movable plate 4 and spring 2 5, thereby effectively reducing the wear of the movable plate 4, thereby effectively improving the stability of the constant force support hanger.
