As shown in fig. 1 to 2, the present embodiment provides a plunger type support-free ductile cast iron pipe connecting device, which comprises a pipe body socket end 1, a pipe body socket end 2, a sealing ring 3, an anti-falling chassis 4 and an anti-falling structure 5; wherein the method comprises the steps of

The pipe body socket end 1 is arranged inside the pipe body socket end 2; the sealing ring 3 is arranged in the pipe body socket end 2, and the sealing ring 3 is used for sealing between the pipe body socket end 2 and the pipe body socket end 1;

the anti-drop chassis 4 is arranged at the end part of the pipe body socket end 2;

the anti-falling structure 5 comprises a socket ring 51 arranged on the socket end 1 of the pipe body and a plunger 52 arranged on the anti-falling chassis 4;

the plunger 52 is mounted in an outboard orientation of the socket ring 51, and the plunger 52 is able to bear against the socket ring 51 to prevent the pipe socket end 1 from being removed from the pipe socket end 2 when the pipe socket end 1 has a tendency to move outwardly.

As a preferred embodiment, in this embodiment, a plurality of plunger through holes are disposed along the radial direction of the anti-drop tray 4 at the outer periphery of the anti-drop tray 4, and the plungers 52 are inserted into the plunger through holes. Typically, the plunger 52 needs to be inserted until it abuts against the outer periphery of the body socket end 1.

As a preferred embodiment, the plunger through holes in this embodiment include a first ring of plunger through holes 6 and a second ring of plunger through holes 7, and a plurality of first plunger through holes 61 are disposed on the first ring of plunger through holes 6, and a plurality of first plunger through holes 61 are disposed along the outer periphery of the anti-falling chassis 4; the second ring plunger through holes 7 are provided with a plurality of second plunger through holes 71, and a plurality of second plunger through holes 71 are arranged along the outer periphery of the anti-drop chassis 4.

In this embodiment, the first plunger through holes 61 and the second plunger through holes 71 are staggered. The number of the first plunger through holes 61 is 2 to 20, and the number of the second plunger through holes 71 is 2 to 20.

It should be noted that, in this embodiment, a plurality of first plunger through holes 61 and a plurality of second plunger through holes 71 are provided and are staggered. Mainly for improving the flexibility of the connection installed between the spheroidal graphite cast iron pipes.

Referring to fig. 1, further explanation is made here that when the central axis of the pipe body socket end 1 is aligned with the central axis of the pipe body spigot end 2, the plunger is inserted into the first ring of plunger through hole 61.

Referring to fig. 2, when the pipe socket end 1 is deviated due to the external installation environment (for example, the pipe socket end 1 is deviated leftwards, rightwards, upwards or downwards relative to the pipe socket end 2), in this case, the central axis of the pipe socket end 1 and the central axis of the pipe socket end 2 form a certain included angle, which is not on the same straight line;

when a first plunger is inserted into the first-round plunger through-hole, there is a case where the plunger is not inserted into the first-round plunger through-hole on the other side of the anti-drop bottom plate 4 with respect to the first plunger (including, but not limited to, a case where the plunger cannot be inserted because the socket ring 51 blocks a part of the plunger through-hole). At this time, on the other side of the anti-drop tray 4 with respect to the other side, it is adopted to insert a plunger in the second-round plunger through hole 7. So as to realize the anti-falling function.

That is, the first ring plunger through hole 6 and the second ring plunger through hole 7 can play a role in preventing falling off as long as the plunger can be inserted.

The ductile cast iron pipe is circular, and some plungers are located below the ductile cast iron pipe in the working condition, and if no plunger positioning steel column 8 is used for clamping the plungers, the plungers are easy to drop.

As a preferred embodiment, the socket ring 51 is disposed around the outer periphery of the socket end 1 of the pipe body in this embodiment.

It should be further noted that in this embodiment, the plunger is inserted from a plunger through hole on the outer periphery of the drop-proof chassis 4, and forms a length of extension body across the inner surface of the drop-proof chassis 4. The socket ring 51 has a first face a and a second face B; when the pipe body socket end 1 moves forwards, the first surface A of the socket ring 51 can be abutted against the end surface of the pipe body socket end 2; when the socket end 1 of the pipe body moves backwards, the second face B of the socket ring 51 can be abutted against the extending body of the plunger;

the device provided by the utility model is additionally provided with the anti-falling chassis 4 and the anti-falling structure 5, wherein the anti-falling structure 5 comprises a socket ring 51 arranged on the socket end 1 of the pipe body and a plunger arranged on the anti-falling chassis 4; the pipe body socket and the pipe body socket end 2 are firmly connected, and are not easy to separate after earthquake or geological change, so that the water leakage event caused by separation in the prior art is overcome. The device provided by the utility model can be used less or even no abutment is needed when the ductile cast iron pipes are connected, and the use of the abutment is effectively reduced under the condition of increasing the structural strength. The plunger through holes in the utility model comprise a first circle of plunger through holes 6 and a second circle of plunger through holes 7, and a plurality of first plunger through holes 61 and a plurality of second plunger through holes 71 are staggered. The staggered arrangement has the advantage that the flexibility of the connection installed between the nodular cast iron pipes can be improved; the device is beneficial to effectively installing under the condition of slope or turning.
