Technical Field
[0001] The present application relates to the technical field of ductile iron pipe elbows, and in particular to an anti-slip and anti-falling device for ductile iron pipe elbows in power tunnels. Background Art
[0002] In the field of power tunnel construction, ductile iron pipes are widely used due to their excellent durability and performance.
[0003] However, in actual application, due to the special shape and connection method of the elbow, this area is prone to unstable connection, easy disconnection and water seepage. These problems not only affect the overall safety and stability of the power tunnel, but may also lead to serious operational failures and increased maintenance costs.
[0004] At present, although there are some solutions on the market for enhancing the stability of elbow connections, such as the use of auxiliary materials such as anti-skid pads, these solutions still have many shortcomings in practical applications. For example, although traditional anti-skid pads can increase friction and reduce sliding to a certain extent, their high cost and limited anti-skid effect often make it difficult to meet actual needs. In addition, these auxiliary materials may also increase installation complexity and maintenance difficulty, thereby reducing overall engineering efficiency.
[0005] Therefore, in response to the problems existing in the elbow connections of ductile iron pipes in power tunnels, an economical and efficient anti-slip and anti-falloff technical solution is urgently needed to improve the stability of the connection, reduce the risks of detachment and water seepage, and thus ensure the long-term safe operation of the power tunnel.

[0009] By adopting the above technical solution, the anti-dropping fixing ring can be fixedly installed at both ends of the elbow body to ensure that it will not fall off, and the connection is convenient and does not require the use of auxiliary tools, and can be manually rotated.
[0010] As a preferred implementation, the number of the connection holes and the number of the bolts are both three, and the three connection holes and the three bolts are distributed in a ring shape on the inner wall of the anti-dropping fixing ring.
[0011] By adopting the above technical solution, the connected pipe can be inserted into the inner wall position of the anti-slip fixing ring, and then the bolts are tightened to the inner wall position of the pipe through the connecting holes to firmly connect the pipe and the anti-slip fixing ring.
[0012] As a preferred embodiment, the anti-slipping fixing ring is made of high-strength alloy, the number of the anti-slipping fixing ring is two, and the two anti-slipping fixing rings are distributed at both ends of the elbow body.
[0013] By adopting the above technical solution, the firmness of the device can be improved, ensuring that the inner wall of the anti-slip fixing ring will not be damaged at will when water flows through and impacts it.
[0014] As a preferred implementation, the inner diameter of the rubber lining is 0.5 mm larger than the inner diameter of the anti-slip fixing ring, and the rubber lining is elastic.
[0015] By adopting the above technical solution, it is possible to provide elastic support when connecting pipes, fill the gaps in the joints, and prevent moisture penetration.
[0016] As a preferred embodiment, the anti-slip gasket is arranged at a middle position between the anti-slip fixing ring and the outer edge of the connecting pipe, and the anti-slip gasket is made of silicone.
[0017] By adopting the above technical solution, friction can be increased, further preventing the pipeline from slipping at the connection point, and thus significantly increasing the friction with the surface of the ductile iron pipe, thereby effectively preventing the elbow body from sliding or disengaging when subjected to external force.
[0018] Beneficial effects of this application:
[0019] 1. The anti-slip and anti-skid device of the ductile iron pipe elbow of the power tunnel is made of high-strength alloy through the anti-slip fixing ring to ensure sufficient supporting force.

[0020] 2. The anti-slip and anti-falling device of the ductile iron pipe elbow in the power tunnel can fix the anti-slipping fixing ring at both ends of the elbow body by connecting the internal thread of the inner wall of the connecting ring to the outer edge of the thread line to ensure that it will not fall off.
