Description

Technical Field

[0001] The utility model relates to the technical field of mechanical maintenance, in particular to a voltage regulator inlet flange turnover platform. Background Art

[0002] The weight of the DN150 / ANSI300 pressure regulator valve body is 480 kg. It is almost impossible to dismantle and overhaul it without safe and reliable lifting equipment. However, due to the circular structure of the valve body, it is still difficult and dangerous to assemble the pressure regulator only with lifting equipment. At the same time, during the overhaul of the DN150 / CLASS300 FL pressure regulator, it is necessary to replace the sealing ring between the inlet flange and the valve body. Since the connecting bolts between the valve body and the inlet flange of the pressure regulator of this specification are inside the valve body, the inlet valve body needs to be turned over before the bolts can be removed during the overhaul. The total weight of the valve body and the inlet flange is about 600 catties. In the past, it took 2-3 people to cooperate to complete the overturn by hooking the bolt hole with a hook, and it was easy to cause the hook to fall, resulting in equipment collision and personal injury. It is a major safety hazard in the maintenance of the pressure regulator. Therefore, we need to propose a pressure regulator inlet flange overturning platform. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 The utility model provides a pressure regulator inlet flange flip platform, including a frame 1 and a valve body 2. A support ring 3 for supporting the valve body 2 is arranged at the center of the top of the frame 1. A positioning component is arranged between the valve body 2 and the support ring 3. The valve body 2 is locked and fixed to the surface of the support ring 3 through the positioning component. The positioning component includes a positioning bolt 5 arranged at the bottom of the support ring 3. The top end of the positioning bolt 5 sequentially penetrates the support ring 3 and the valve body 2 and extends to the top of the valve body 2 and is threadedly connected with a positioning nut 6. The bottom of the positioning nut 6 fits with the surface of the valve body 2.

[0020] By setting the positioning assembly, the valve body 2 that needs to be repaired can be installed and fixed on the surface of the support ring 3. During installation, the user can place the valve body 2 on the top of the support ring 3, and then pass the top end of the positioning bolt 5 through the support ring 3 and the valve body 2 and tighten the positioning nut 6 at its top end to lock the valve body 2 on the support ring 3.

[0021] A flip assembly for flipping the valve body 2 is installed on the top of the frame 1, and the flip assembly includes a flip shaft 7 fixedly installed on both sides of the support ring 3. A gear box 8 is fixedly installed on one side of the top of the frame 1, and the input shaft of the gear box 8 is fixedly connected to a handwheel 9. One end of one group of flip shafts 7 is fixedly connected to the output shaft of the gear box 8, and the other group of flip shafts 7 is rotatably installed on the top of the frame 1 through the support assembly. The support assembly includes a support frame 10 fixedly installed on the top of the frame 1, and a thrust bearing 11 is fixedly installed on the top of the support frame 10. One end of the flip shaft 7 is keyed to the inner ring of the support shaft 14.

[0022] After the valve body 2 is fixed on the top of the support ring 3, the user can turn the hand wheel 9. The rotation of the hand wheel 9 will drive one set of the flip shafts 7 to rotate through the gear box 8, so as to drive the support ring 3 and the valve body 2 to flip, and stop rotating after flipping 180 degrees. In this embodiment, the reduction ratio of the gear box 8 is 10:1, and the total weight of the support ring 3, the flip shaft 7 and the thrust bearing 11 is greater than 1.5 times the weight of the valve body 2. Through the setting of the support assembly, the other set of flip shafts 7 can play an auxiliary supporting role to improve the stability of the flipping of the support ring 3 and the valve body 2.

[0023] It is worth mentioning that the inner cavity of the frame 1 is provided with a support plate 4, and a lifting assembly is installed at the bottom of the support plate 4. The lifting assembly includes a support seat 16 fixedly installed on the top of the slider 15, and a worm gear lift 17 is fixedly installed on the top of the support seat 16. A lifting screw 18 is installed on the worm gear lift 17. The top of the lifting screw 18 is fixedly connected to the bottom of the support plate 4, and the input end of the worm gear lift 17 is fixedly connected with a hand wheel 2 19. A movable mounting assembly is arranged between the lifting assembly and the frame 1, and the lifting assembly and the support plate 4 are movably connected to the inner cavity of the frame 1 through the movable mounting assembly. The movable mounting assembly includes two sets of fixed frames 12 fixedly installed at the bottom of the inner cavity of the frame 1, and fixed plates 13 are fixedly installed on the front and rear sides of the top of the fixed frame 12. A support shaft 14 is fixedly installed between the two sets of fixed plates 13, and a slider 15 is slidably connected to the surface of the support shaft 14.

[0024] Through the setting of the movable installation component, after the valve body 2 is flipped, the user can move the support plate 4 to the bottom of the valve body 2 by pushing the support seat 16. Through the coordinated use of the lifting component and the support plate 4, after the valve body 2 is flipped, the user can turn the hand wheel 2 19. The rotation of the hand wheel 2 19 will drive the lifting screw 18 to move through the worm gear lift 17, thereby driving the support plate 4 to move upward to support the valve body 2. Then the user can remove the internal bolts of the valve body 2, easily separate the outlet flange from the valve body 2, clean the interior, replace the sealing ring, and then perform the reverse installation.

[0025] In addition, a through hole 20 is opened on the surface of the support seat 16 and at a corresponding position of the lifting screw 18. The surface of the lifting screw 18 is slidably connected to the inner cavity of the through hole 20. Through the setting of the through hole 20, a moving space can be provided for the lifting screw 18. When it moves downward, the bottom of the lifting screw 18 will pass through the through hole 20 and extend to the bottom of the support seat 16.
