DETAILED DESCRIPTION

[0024] The utility model is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the utility model in a schematic manner, so they only show the components related to the utility model.

[0025] like Figure 1-Figure 3As shown, a constant force disc spring bracket includes a box body 100, a pressure plate 200, a pull rod 300, a pressure assembly 400, a linkage assembly 500, a disc spring group 600 and a weighing sensor 700. The box body 100 is hollow in the shape of a "concave" character. The pressure plate 200 is arranged directly above the box body 100. The pull rod 300 is symmetrically arranged at the left and right ends of the box body 100. The pull rod 300 slides through the top plate of the box body 100, and its top end is connected to the pressure plate 200. The pressure assembly 400 slides through the middle of the top plate of the box body 100 and the middle of the pressure plate 200, and its bottom end is connected to the bottom ends of the two pull rods 300 through the linkage assembly 500 respectively. The disc spring group 600 is arranged between the box body 100 and the pressure plate 200, and is sleeved on the pressure assembly 400. The weighing sensor 700 is installed on the top of the pressure assembly 400. The box body 100 is designed to be a hollow "concave" shape, and the bottom end of the pull rod 300 and the bottom end of the pressing assembly 400 are connected by the linkage assembly 500, so that the structural design is compact and the overall height is reduced, so that it can adapt to a small space. Combined with the setting of the weighing sensor 700, the supporting load of the pipeline or equipment can be seen in real time and intuitively, so that the judgment of the supporting force is simple and reliable. Specifically, the linkage assembly 500 is divided into two groups, which are symmetrically arranged on the left and right sides of the pressing assembly 400; the box body 100 is provided with an outer cover tube 1000 to protect the pressing plate 200.

[0026] like Figure 1 and Figure 4 As shown, the pressing assembly 400 includes a sleeve 410, a screw 420, a load plate 430 and a cross plate 440. The sleeve 410 slides through the middle of the top plate of the box 100 and the middle of the pressing plate 200, and its bottom end is connected to the middle of the top of the cross plate 440. The screw 420 is arranged in the sleeve 410 and threadedly matched with the sleeve 410. The top of the screw 420 extends out of the sleeve 410 and is connected to the bottom of the load plate 430. The weighing sensor 700 is installed at the top of the load plate 430. The height of the load plate 430 can be adjusted by rotating the screw 420 to further adapt to the distance between the pipeline or equipment and the foundation.

[0027] like Figure 3 and Figure 4As shown, the linkage assembly 500 includes a rotating frame 510, a main shaft 520, a roller 530, a pull plate 540 and a joint 550. The rotating frame 510 is mirror-imaged on the left and right sides of the horizontal plate 440, and its end away from the horizontal plate 440 is rotatably connected to the box 100 through the main shaft 520. The roller 530 is rotatably installed at the end of the rotating frame 510 close to the horizontal plate 440. The left and right ends of the horizontal plate 440 are respectively overlapped on the roller 530. The pull plate 540 is symmetrically arranged on the front and rear sides of the rotating frame 510. The bottom end of the pull plate 540 is hinged to the middle of the rotating frame 510, and the top end is hinged to the joint 550. The joint 550 is installed at the bottom end of the pull rod 300. The supporting force is transmitted through two sets of linkage assemblies 500, so that the pipeline or equipment produces vertical displacement without deflection or offset.

[0028] like Figure 4 and Figure 5 As shown, the linkage assembly 500 further includes a mirror stainless steel plate 560, which is respectively mounted on the bottom surfaces of the left and right ends of the horizontal plate 440 and contacts the roller 530. The setting of the mirror stainless steel plate 560 reduces the friction between the horizontal plate 440 and the roller 530 and prolongs the service life.

[0029] like Figure 5 As shown, the pressing assembly 400 further includes a limiting plate 450, which is symmetrically mounted on the front and rear sides of the horizontal plate 440, and the end of the rotating frame 510 close to the horizontal plate 440 is located between the two limiting plates 450. The two limiting plates 450 are arranged to limit the rolling direction of the roller 530, thereby preventing the pressing assembly 400 from deflecting or offsetting.

[0030] like Figure 2 and Figure 3 As shown, the constant force disc spring bracket also includes a guide assembly 800, which includes a fixed plate 810, a guide rod 820 and an adjusting nut 830. The fixed plate 810 is arranged above the pressure plate 200, and the sleeve 410 slides through the center of the fixed plate 810. The guide rod 820 slides through the pressure plate 200 and the fixed plate 810, and its bottom end is connected to the top plate of the box body 100. The adjusting nut 830 is symmetrically arranged on the upper and lower sides of the fixed plate 810 and is threadedly sleeved on the guide rod 820. The setting of the guide assembly 800 guides the lifting and lowering of the pressure plate 200. By rotating the adjusting nut 830, the height of the fixed plate 810 can be adjusted to adapt to the lifting and lowering stroke of the pressure plate 200. Specifically, there are four guide rods 820, which are evenly arranged along the circumference of the sleeve 410.

[0031] like Figure 1-Figure 3 , Figure 5As shown, the left and right ends of the limit plate 450 are respectively installed with a shipping assembly 900, and the shipping assembly 900 includes a positioning pin 910, a tooth block 920 and a rack 930. The positioning pin 910 is longitudinally installed on the two limit plates 450, and its two ends respectively pass through the waist hole 110 opened on the box body 100, and the positioning pin 910 and the waist hole 110 are clearance-matched. The tooth block 920 is respectively installed at the two ends of the positioning pin 910, and the rack 930 is symmetrically arranged on the left and right sides of the tooth block 920 and installed on the outside of the box body 100. The tooth block 920 is meshed with the rack 930. Through the setting of the shipping assembly 900, the pressing assembly 400 is locked to avoid overpressure of the disc spring group 600 during transportation. Specifically, the tooth block 920 is slidably matched with the positioning pin 910 and is limited by the retaining spring. When the constant force disc spring bracket is transported to the place for use, the retaining ring is removed and the tooth block 920 is taken off, so that the positioning pin 910 can move freely in the waist hole 110.

[0032] In the initial state, the disc spring assembly 600 contacts the pressure plate 200 so that the pressure plate 200 is located above the box 100. When the pipeline and equipment are displaced due to thermal expansion and contraction or vibration, the pressing assembly 400 produces a vertical displacement, for example, the pressing assembly 400 moves downward, and the downward movement of the pressing assembly 400 presses down the end of the rotating frame 510 close to the horizontal plate 440 through the horizontal plate 440, forcing the rotating frame 510 to rotate around the main axis 520. At this time, the roller 530 rolls on the mirror stainless steel plate 560, and the rotation of the rotating frame 510 pulls down the pull rod 300 through the pull plate 540, thereby synchronously pulling the pressure plate 200 downward, and the pressure plate 200 squeezes the disc spring assembly 600.

[0033] The above-mentioned implementation mode is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
