Description
Technical Field
[0001] This application relates to the field of supports and hangers, and in particular to an auxiliary tooling for adjusting large supports and hangers. Background Technology
[0002] In thermal power plants, due to space constraints, hangers are often used to secure the boiler body or piping. One end of the hanger is fixed to the boiler body or piping, and the other end is bolted to an overhead steel beam, thus providing stable support for the boiler body or piping. However, adjusting the position of the boiler body or piping often presents difficulties due to various reasons, such as working at height, heavy loads on the hangers, and bolt corrosion after long-term operation. This can lead to long-term disrepair of the hangers, posing a safety hazard to the safe and stable operation of the unit.
[0003] Currently, the auxiliary adjustment measures mainly involve manual chain hoists and hydraulic jacks. The manual chain hoist is fixed to the boiler body or pipes, and then a pulling force is applied to suspend the boiler body or pipes, reducing the load on the hanger, which is then adjusted. Similarly, a hydraulic jack is used to lift the boiler body or pipes, thereby relieving the load on the hanger, which is then adjusted. However, these methods have problems such as high risk of use, low adjustment efficiency, and inconvenience. Summary of the Invention
[0004] To make hanger adjustment more convenient and efficient, this application provides an auxiliary tooling for adjusting large hangers.
[0005] This application provides an auxiliary tooling for adjusting large supports and hangers, which adopts the following technical solution: An auxiliary tooling for adjusting large supports and hangers includes: Horizontal board; The first vertical plate and the second vertical plate are both set on the horizontal plate. The first vertical plate and the second vertical plate are both located below the horizontal plate and are both perpendicular to the horizontal plate. The first vertical plate and the second vertical plate are parallel to each other. A connecting block is disposed on the first vertical plate and the second vertical plate, located between the first vertical plate and the second vertical plate, and with a gap between it and the horizontal plate. The connecting block has a first through hole for the hanger rod of the hanger to pass through. A set of fixing nuts is provided on the connecting block and communicates with the first through hole on the connecting block. The set of fixing nuts is threadedly engaged with the lifting rod passing through the first through hole. An adjustment assembly, mounted on the steel beam and connected to the cross plate, is used to lift the cross plate. The limiting block assembly, located between the connecting block and the steel beam, is used to support and limit the connecting block, restricting it to a specified height.
[0006] By adopting the above technical solution, the horizontal plate is used to fix the first and second vertical plates, and the first and second vertical plates are used to fix the connecting block. A gap is left between the connecting block and the horizontal plate, so that the hanger rod can pass through the first through hole of the steel beam and the connecting block and the fixing nut group can be screwed onto the hanger rod. The worker tightens the fixing nut group, thereby fixing the hanger rod and changing the stress point of the hanger from below the steel beam to above the steel beam. When the worker needs to adjust the hanger, the worker lifts the horizontal plate by adjusting the component. The horizontal plate drives the first and second vertical plates, the connecting block and the hanger rod on the connecting block to move vertically upward. After adjusting to the required position, the limiting block group is placed between the connecting block and the steel beam, thereby supporting and limiting the connecting block and fixing the displacement of the adjusted hanger rod. That is, the longitudinal displacement adjustment of the hanger rod is performed from above the steel beam. Compared with the current use of hand hoists, jacks and other tools to adjust the hanger, it is more efficient and convenient.
[0007] Optionally, the adjustment assembly includes two jacks, the cylinders of the two jacks are mounted on the steel beam, the telescopic rods of the two jacks are mounted on the bottom surface of the horizontal plate, the two jacks are respectively located on the side of the first vertical plate opposite to the connecting block and the side of the second vertical plate opposite to the connecting block, and the first vertical plate and the second vertical plate are located between the two jacks.
[0008] By adopting the above technical solution, by setting two jacks to apply upward thrust to the horizontal plate on both sides of the first and second vertical plates respectively, the force on the horizontal plate is more even. Using two jacks makes the adjustment of the hanger more reliable and can lift a larger load.
[0009] Optionally, the limiting block group includes multiple sub-limiting blocks, each sub-limiting block consisting of two limiting parts, each limiting part having a semi-circular notch.
[0010] By adopting the above technical solution, after adjusting the hanger, the two limiting parts of the sub-limiting block are brought closer to each other from both sides of the hanger, thus merging into a single sub-limiting block. Multiple sub-limiting blocks can improve the adjustment range of the hanger.
[0011] Optionally, the thicknesses of the multiple sub-limiting blocks in the limiting block group are different.
[0012] By adopting the above technical solution, the adjustment of the hanger can be made more flexible by using multiple sub-limiting blocks of different thicknesses, and can be adjusted to various required displacement amounts according to needs.
[0013] Optionally, the fixing nut assembly includes a first nut and a second nut, wherein the thickness of the first nut is less than that of the second nut, and the first nut is located below the second nut.
[0014] By adopting the above technical solution, the first nut and the second nut are tightened on the hanger rod of the hanger, making the hanger rod more firmly fixed on the connecting block and preventing the hanger rod from loosening.
[0015] Optionally, a third vertical plate is provided on the horizontal plate, the third vertical plate is perpendicular to the horizontal plate, and the length direction of the third vertical plate is consistent with the length direction of the horizontal plate; The horizontal plate is provided with multiple reinforcing plates, which are located on both sides of the third vertical plate. One end of each reinforcing plate is fixed to the horizontal plate and the other end is fixed to the third vertical plate.
[0016] By adopting the above technical solution, the third vertical plate is set vertically on the horizontal plate, thereby improving the strength of the horizontal plate. When the jack lifts the horizontal plate, the horizontal plate is not easily deformed. The setting of multiple reinforcing plates further increases the strength of the horizontal plate.
[0017] Optionally, a first fixing bolt is threaded onto the connecting block, and a limiting piece is provided on the connecting block, with the first fixing bolt passing through one end of the limiting piece.
[0018] By adopting the above technical solution, the limiting plate plays a blocking and restricting role on the limiting block, making it difficult for the limiting block to fall off the steel beam. After the first fixing bolt is tightened, the limiting plate becomes more secure, improving the blocking effect of the limiting plate on the limiting block.
[0019] Optionally, the limiting plate has an elongated second through hole, and a second fixing bolt is provided on the limiting plate, the second fixing bolt passing through the second through hole; the steel beam has a threaded hole, and the second fixing bolt passes through the second through hole and engages with the threaded hole.
[0020] By adopting the above technical solution, the second fixing bolt slides freely in the elongated second through hole, making the second fixing bolt more flexible. After the hanger is adjusted to the required position, the second fixing bolt is tightened into the threaded hole on the steel beam. The first fixing bolt and the second fixing bolt work together to further improve the firmness of the limiting plate and improve the limiting and blocking effect on the limiting block.
[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The horizontal plate is used to fix the first and second vertical plates, which in turn are used to fix the connecting block. A gap is left between the connecting block and the horizontal plate, allowing the hanger rod to pass through the first through hole in the steel beam and the connecting block, and the fixing nut assembly to be screwed onto the hanger rod. The worker tightens the fixing nut assembly, thus fixing the hanger rod and changing the stress point of the hanger from below the steel beam to above the steel beam. When the worker needs to adjust the hanger, the worker lifts the horizontal plate by adjusting the assembly. The horizontal plate drives the first and second vertical plates, the connecting block, and the hanger rod on the connecting block to move vertically upward. After adjusting to the required position, the limiting block assembly is placed between the connecting block and the steel beam, thus supporting and limiting the connecting block and fixing the displacement of the adjusted hanger rod. That is, the hanger rod of the hanger is adjusted longitudinally from above the steel beam, which is more efficient and convenient than the current method of adjusting the hanger using a hand hoist or jack.
[0022] 2. The use of multiple sub-limiting blocks of different thicknesses allows for more flexible adjustment of the hanger, enabling it to be adjusted to various required displacement amounts as needed. Attached Figure Description

Detailed Implementation
[0026] The present application will be further described in detail below with reference to the accompanying drawings.
[0027] This application discloses an auxiliary tooling for adjusting large supports and hangers.
[0028] Reference Figure 1 and Figure 2An auxiliary tooling for adjusting a large support bracket includes a horizontal plate 1, a first vertical plate 21, a second vertical plate 22, a connecting block 23, an adjusting assembly 4, a fixing nut assembly 3, and a limiting block assembly 5. The hanger rod 100 of the bracket is threaded. The hanger rod 100 passes through the steel beam 10 and then through the first through hole 231 on the connecting block 23. The operator then uses the fixing nut assembly 3 to tighten it onto the thread of the hanger rod 100, thus fixing the hanger rod 100 to the connecting block 23.
[0029] Reference Figure 1 and Figure 2 The first vertical plate 21 and the second vertical plate 22 are both welded to the horizontal plate 1 and are both located below the horizontal plate 1. The first vertical plate 21 and the second vertical plate 22 are parallel to each other. The connecting block 23 is located between the first vertical plate 21 and the second vertical plate 22, and the connecting block 23 is welded to the first vertical plate 21 and the second vertical plate 22 respectively. A gap is left between the connecting block 23 and the horizontal plate 1, so that one end of the lifting rod 100 is located in the gap, and it is convenient to screw the fixing nut assembly 3 onto the lifting rod 100 in the gap. The adjusting assembly 4 includes two jacks 41. The two jacks 41 are located on the side of the first vertical plate 21 away from the connecting block 23 and the side of the second vertical plate 22 away from the connecting block 23 respectively. That is, the first vertical plate 21, the second vertical plate 22 and the connecting block 23 are located between the two jacks 41. When the hanger needs adjustment, the operator can place two jacks 41 on the steel beam 10. The telescopic rods of the two jacks 41 press against the horizontal plate 1, applying a pushing force to the horizontal plate 1, causing it to move vertically upward. During the movement of the horizontal plate 1, the first vertical plate 21, the second vertical plate 22, the connecting block 23, and the hanger's rod 100 move upward, thus adjusting the hanger. After adjustment to the desired position, a gap appears between the connecting block 23 and the steel beam 10. The operator places the sub-limiting block 51 from the limiting block group 5 into the gap, thereby fixing the displacement of the hanger 100 and preventing it from falling back. Then, the operator can remove the two jacks 41, keeping the hanger's rod 100 at the adjusted height. In other embodiments, the cylinders of the two jacks 41 can be fixedly connected to the steel beam 10, and the telescopic rods can be fixedly connected to the horizontal plate 1. The fixed connection can be achieved by welding.
[0030] To allow for more flexible adjustment of the distance of the hanger rod 100, refer to Figure 1 and Figure 2The limiting block group 5 consists of multiple sub-limiting blocks 51, and the thickness of the sub-limiting blocks 51 is also different. Specifically, the thickness of the sub-limiting blocks 51 can be 3cm, 1cm, 5cm, etc. The number of sub-limiting blocks 51 of each thickness can be one or more. Each sub-limiting block 51 consists of two limiting parts 521. The sub-limiting block 51 is generally square, and each limiting part 521 has a notch 522, which is semi-circular. After the hanger rod 100 is adjusted to the required position, the operator moves the two limiting parts 521 of the sub-limiting block 51 from below the connecting block 23, so that the notches 522 of the two limiting parts 521 cover the hanger rod 100, and the sub-limiting block 51 fits more closely with the connecting block 23.
[0031] To ensure the hanger rod 100 is more securely fixed to the connecting block 23, refer to... Figure 1 and Figure 2 The fixing nut assembly 3 includes a first nut 31 and a second nut 32, where the thickness of the first nut 31 is less than that of the second nut 32. When fixing the boom 100, the operator first screws the first nut 31 onto the boom 100 and tightens it against the upper surface of the connecting block 23. Then, the operator screws the second nut 32 onto the boom 100 and tightens it against the upper surface of the first nut 31. The cooperation between the first nut 31 and the second nut 32 makes the boom 100 more securely fixed, and the fixing nut assembly 3 and the boom 100 are less likely to loosen.
[0032] To improve the strength of the horizontal plate 1, refer to Figure 1 and Figure 2 A third vertical plate 61 is fixedly connected to the upper surface of the horizontal plate 1. Specifically, the third vertical plate 61 can be welded to the horizontal plate 1. The third vertical plate 61 is perpendicular to the horizontal plate 1, and its length direction is consistent with that of the horizontal plate 1. The third vertical plate 61 is located in the middle of the horizontal plate 1. The third vertical plate 61 increases the strength of the horizontal plate 1, making it less prone to deformation when the two jacks 41 lift it. Furthermore, multiple reinforcing plates 62 are welded to the horizontal plate 1. The reinforcing plates 62 are triangular and are respectively arranged on both sides of the third vertical plate 61 at equal intervals. The two right-angled sides of the reinforcing plates 62 are welded to the horizontal plate 1 and the third vertical plate 61, respectively. By setting the reinforcing plates 62, the strength of the horizontal plate 1 is further improved.
[0033] To ensure greater stability of the sub-limiting block 51 between the connecting block 23 and the steel beam 10, refer to... Figure 1 and Figure 2A first fixing bolt 71 is threadedly connected to the side of the connecting block 23. A limiting piece 72 is provided on the first fixing bolt 71. The first fixing bolt 71 passes through the limiting piece 72 and is threadedly connected to the connecting block 23. The limiting piece 72 can rotate along the first fixing bolt 71. A long strip-shaped second through hole 721 is opened on the limiting piece 72. A second fixing bolt 73 is placed in the second through hole 721 and can slide freely in the second through hole 721. A threaded hole (not shown in the figure) is opened on the steel beam 10 to cooperate with it. The second fixing bolt 73 is threadedly engaged with the threaded hole on the steel beam 10. After the worker places the sub-limiting block 51 between the connecting block 23 and the steel beam 10, the worker tightens the first fixing bolt 71 and the second fixing bolt 73, so that the limiting piece 72 blocks the sub-limiting block 51, making it difficult for the sub-limiting block 51 to fall off. Furthermore, a set of first fixing bolts 71, limiting plates 72, and second fixing bolts 73 are provided on both sides of the connecting block 23 adjacent to the first vertical plate 21 and the second vertical plate 22, thereby blocking and limiting the sub-limiting block 51 from all directions. In order to make the blocking effect of the limiting plates 72 more effective, when placing the sub-limiting block 51, the operator places the two limiting parts 521 of the sub-limiting block 51 from the side where the limiting plates 72 are provided. Since the limiting parts 521 have semi-circular notches 522, after the two limiting parts 521 are combined, the hanging rod 100 is located in the two notches 522, which plays a limiting role on the sub-limiting block 51. The limiting block is not easy to fall off from the side. The use of the two limiting plates 72 together makes the sub-limiting block 51 more stable. In other embodiments, after the staff adjusts the hanger to the required position and places the sub-limiting block 51, the bottom sub-limiting block 51 can be welded to the steel beam 10, and then multiple sub-limiting blocks 51 can also be welded together to form a whole, making the connection between the limiting block and the steel beam 10 more stable.
[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
