Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to pipeline pouring technical field, and especially relates to centrifugal counterweight assembly. BACKGROUND
[0002] Centrifugal casting method is a method for forming tubular or hollow cylindrical products by using centrifugal force, which places the casting raw material in a rotating centrifugal mold or hollow pipe, and makes it rotate at high speed around a single shaft. At this time, the casting raw material put in is forced to be distributed in the near wall part of the mold by centrifugal force.
[0003] For the centrifugal casting of straight pipes, the straight pipes are usually directly placed in the centrifugal device for centrifugal casting. However, for pipes with branch pipes, due to the existence of branch pipes, there are problems of pipe deflection during centrifugation, which reduces the service life of the centrifuge and causes uneven distribution of centrifugal lining material. At present, for the pipes with branch pipes, the same mass counterweight block is usually welded at the symmetrical position of the pipe branch to achieve mass balance during pouring. However, after pouring is completed, the surface of the pipe will be damaged when the counterweight block is removed, which affects the pouring quality of the pipe and is time-consuming and costly.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a centrifugal counterweight assembly 1, which is installed on a pipe 2 and used as a counterweight during centrifugal casting of the pipe 2. The pipe 2 includes a straight pipe 21 and a branch pipe 22, with the branch pipe 22 located on the straight pipe 21 and in a position perpendicular to the straight pipe 21. The centrifugal counterweight assembly 1 is installed at the connection between the straight pipe 21 and the branch pipe 22.
[0024] The centrifugal counterweight assembly 1 includes a fixing member 11 and a counterweight member 12. The counterweight member 12 is connected to the fixing member 11 and is installed on the pipe 2 through the fixing member 11.
[0025] Specifically, the fastener 11 has two mirror-symmetrical structures, including a fixing part 111 and a mounting part 112. The mounting part 112 is installed below the fixing part 111. The fixing part 111 is used to connect with the pipe 2, and the mounting part 112 is used to install the counterweight 12.
[0026] The fixing part 111 is a hollow cylinder. When installed on the pipe 2, the two mirror-symmetrical fixing parts 111 form a cylindrical whole that wraps around the straight pipe 21. Therefore, the inner diameter of the fixing part 111 is the same as the outer diameter of the straight pipe 21, allowing the fixing part 111 to fit snugly against the straight pipe 21 and maintain a stable state during centrifugal operation. A fixing plate 1111 is provided on the fixing part 111. The fixing plate 1111 and the mounting part 112 are symmetrical about the center of the fixing part 111. The fixing part 111 is fixedly installed on the straight pipe 21 through the fixing plate 1111. In this embodiment, the fixing plate 1111 has screw holes, and each set of fixing plates is connected and fixed through the screw holes. Simultaneously, the fixing part 111 also has fixing holes 1112. When the fixing part is installed on the straight pipe 21, the branch pipe 22 passes through the fixing holes 1112. The fixing hole 1112 and the mounting part 112 are symmetrical about the center of the fixing part 111, which ensures that the mounting part 112 and the branch pipe 22 are in a symmetrical position. The inner diameter of the fixing hole 1112 is greater than or equal to the outer diameter of the branch pipe 22. In a preferred embodiment, the inner diameter of the fixing hole 1112 is the same as the outer diameter of the branch pipe 22. In this embodiment, two sets of fixing pieces 1111 are provided on the fixing part 111, and the fixing hole 1112 is located between the two sets of fixing pieces 1111.
[0027] The mounting portion 112 is approximately inverted "T" shaped, including a connecting piece 1121 and a mounting piece 1122 arranged perpendicularly to each other. The mounting piece 1122 is mounted on the fixing portion 111 via the connecting piece 1121. The mounting piece 1122 has multiple first mounting holes 1123, and the counterweight 12 has multiple second mounting holes 121. The second mounting holes 121 match the first mounting holes 1123, allowing the counterweight 12 to be mounted onto the mounting portion 112 through both the second mounting holes 121 and the first mounting holes 1123. In this embodiment, the counterweight 12 is plate-shaped, and multiple counterweights can be stacked. The specific number and weight of the counterweights 12 are selected based on the weight of the branch pipe 22.
[0028] In use, first, the fixing member 11 is fitted onto the straight pipe 21, so that the branch pipe 22 passes through the fixing hole 1112. Then, the corresponding fixing piece 1111 and the connecting piece 1121 are connected and fixed to each other. Finally, according to the weight of the branch pipe 22, a suitable weight and number of counterweights 12 are selected and installed on the mounting piece 1122 to balance the counterweights 12 with the branch pipe 22.
[0029] like Figure 3 and Figure 4As shown, in another embodiment, the fixing member 11 further includes two opposing clamping portions 113, which are installed between two mirror-symmetrical fixing plates 1111 for clamping the branch pipe 22. Specifically, the clamping portion 113 includes a mounting plate 1131 and a clamping plate 1132. The mounting plate 1131 is installed at the bottom edge of the clamping plate 1132. After the clamping plate 1132 is installed on the fixing plate 1111 via the mounting plate 1131, the clamping plate 1132 is located above the fixing hole 1112 and is arc-shaped. When the branch pipe 22 passes through the fixing hole 1112, the position of the mounting plate 1131 can be adjusted to clamp the branch pipe 22 with the opposing clamping plates 1132. The clamping portion 113 allows the fixing member 11 to be adapted to branch pipes 22 of different diameters, improving the versatility of the centrifugal counterweight assembly 1.
[0030] Furthermore, the pipe 2 mentioned in this utility model can be either the pipe product itself with branch pipes or a tubular mold used to produce pipes with branch pipes.
[0031] In summary, the centrifugal counterweight assembly 1 provided by this utility model, through the cooperation of the fixing member 11 and the counterweight member 12, can be flexibly applied to the centrifugal casting of the pipe 2 with branch pipes 22 of different weights, thereby improving the efficiency and quality of the pipe 2 manufacturing.
[0032] Although the present invention has been described and illustrated in detail with reference to preferred embodiments, the present invention is not limited to the disclosed examples, and those skilled in the art can derive other variations therefrom without departing from the protection scope of the present invention.
