[0033] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0034] In order to make those skilled in the art better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0035] It should be noted that in the present embodiment, the directions or position relationships indicated by "up", "down", "front", "back" and the like are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, "first", "second", "third", "fourth" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0036] As Figure 1As shown, in the embodiment, a mechanical construction method for socket and spigot PVC pipes is provided, which comprises the following steps:

[0037] Step S1, initially butt joint the socket 1 and the spigot 2; that is, insert the end of the spigot 2 into the socket 1 by a certain distance, so as to ensure that the socket 1 and the spigot 2 have a certain initial connection amount, facilitating the subsequent continuous insertion action;

[0038] Step S2, set the sleeve 3 at the insertion position of the socket 1 and the spigot 2, lock the sleeve 3, and make the inner wall of the sleeve 3 respectively adhere to the outer wall of the socket 1 and the outer wall of the spigot 2; since the sleeve 3 respectively adheres to the outer wall of the socket 1 and the outer wall of the spigot 2, it can play a certain limiting role on the socket 1 and the spigot 2, that is, it can limit the upward and downward displacement of the two pipe openings during the force process, and also can increase the force area of the socket and spigot PVC pipe, so as to prevent the socket and spigot PVC pipe from being damaged during the construction process;

[0039] Of course, the sleeve 3 adheres to the outer wall of the socket 1 and the outer wall of the spigot 2, but in order to realize the insertion of the spigot 2 and the socket 1, the setting of the sleeve 3 does not affect the relative movement of the spigot 2 and the socket 1; what the sleeve 3 of the embodiment emphasizes is that it can play a certain limiting and supporting role on the socket 1 and the spigot 2 while not affecting the relative movement of the socket 1 and the spigot 2, so as to prevent the upward and downward displacement of the two pipe openings during the force process.

[0040] Step S3, set the rope 4 outside the sleeve 3, and connect the other end of the rope 4 with the power end of the power member 5; the power member 5 can drive the movement of the rope 4 and the sleeve 3, so as to drive the movement of the socket 1 facing the spigot 2, and realize the insertion of the two; of course, the rope 4 here can be replaced by other ways, as long as it can drive the movement of the sleeve 3, which will not be described here, and all falls within the protection scope of the present application;

[0041] In addition, the sleeve 3 and the socket 1 are driven to move by the rope 4, and the force is located on the sleeve 3, which can also act on the end position of the socket 1; by using the pulling mode of the rope 4, the end of the socket 1 can bear the pulling force instead of the pushing force, and the pulling force can make the insertion of the socket 1 and the spigot 2 more smooth, and reduce the arching and concave deformation of the socket and spigot PVC pipe.

[0042] Step S4, input the displacement change per minute of the power member 5, and set the maximum displacement value; control the load applied by the power member 5 to the sleeve 3 through the displacement index, so that the sleeve 3 drives the socket 1 to move towards the spigot 2, and the two are mutually butted to form a whole according to the uniform displacement change, and are inserted to the standard displacement value; at the same time, the load value of the power member 5 can be monitored, when the load value appears too large, the butt joint of the socket 1 and the spigot 2 needs to be checked whether there is a problem, until all problems are excluded, the construction can continue, so as to avoid the butt joint not in place;

[0043] After the spigot 1 and the socket 2 are inserted, the power member 5 is closed, the rope 4 is removed, the sleeve 3 is opened and taken off, and the spigot and socket PVC pipe construction work is completed.

[0044] The steps S1-S5 are repeated to construct the next spigot and socket pipe.

[0045] In summary, the sleeve 3 load can be automatically controlled according to the power member 5 displacement per minute value, the spigot and socket PVC pipe is uniformly stressed, and the labor cost is saved by replacing the manpower. At the same time, the pushing force is converted into pulling force by the rope 4 and the sleeve 3, and the sleeve 3 is used to fix and limit the up and down displacement of the spigot and socket PVC pipe, reducing the arching and sagging deformation, saving construction time, ensuring the butt joint accuracy, and improving the construction quality. In addition, the sleeve 3 and the rope 4 are combined to apply load to the spigot and socket PVC pipe, which can avoid the rope 4 directly acting on the surface of the spigot and socket PVC pipe, and the stress is uniform, which will not damage the surface of the spigot and socket PVC pipe.

[0046] In addition, the sleeve 3 includes two half-cylindrical structures, which are buckled at the insertion part of the spigot 1 and the socket 2. Specifically, in order to facilitate the installation and removal of the sleeve 3, the sleeve 3 is provided as two mutually buckled parts. When installing, the two half-cylindrical structures are buckled at the spigot 1 and the socket 2, and the two half-cylindrical structures are locked. When removing, the two half-cylindrical structures are loosened, and then the two half-cylindrical structures are removed, which is convenient and fast.

[0047] Of course, the locking member 6 is arranged on the two half-cylindrical structures. The locking member 6 can be locked by bolts and nuts, or other clamping methods, which are not limited here, as long as the two half-cylindrical structures can be completely buckled and stably locked.

[0048] It should be noted that a rubber layer is arranged on the inner wall of the sleeve 3, which contacts the outer wall of the spigot 1 and the socket 2. This can not only protect the surface of the spigot and socket PVC pipe from damage caused by rigid contact, but also increase the friction between the sleeve 3 and the spigot 1, facilitating the movement of the spigot 1.

[0049] Since the end of the socket 1 needs to be inserted into the socket 2, the end of the socket 1 will have an annular protrusion 7 with a large inner and outer diameter. In this embodiment, a first inner groove is provided on the inner wall of the sleeve 3 to engage with the annular protrusion 7. That is, the first inner groove can cooperate with the annular protrusion 7, thereby driving the annular protrusion 7 and the socket 1 to move during the movement of the sleeve 3. In addition, a second inner groove is provided on the inner wall of the other side of the sleeve 3 to cooperate with the outer wall of the socket 2. The second inner groove is cylindrical and matches the outer periphery of the socket 2. The setting of the second inner groove is just to ensure that it has a certain upper and lower limiting effect on the socket 2 to prevent the socket 2 from shaking up and down in the socket 1.

[0050] To ensure uniform force distribution on the sleeve 3 during movement, at least two power components 5 are installed, evenly distributed around the outer periphery of the socket 1 or insert 2. Specifically, the rope 4 connected to the power end of the power component 5 must exert a balanced force on the sleeve 3 to prevent one side of the sleeve 3 from experiencing greater force than the other. Of course, the power component 5 can be a hydraulic cylinder or a pneumatic cylinder, etc., without further restrictions.

[0051] Based on the above embodiments, when the sleeve 3 is moved by the rope 4, a groove can be provided around the outer periphery of the sleeve 3 to engage the rope 4, thereby ensuring that the outer periphery of the sleeve 3 is evenly stressed. Of course, other fixing methods can also be used to connect the rope 4 and the sleeve 3, such as connecting lugs with through holes, where the rope 4 passes through the through hole of the connecting lug and is fixed to the sleeve 3. These methods will not be detailed here, but all fall within the scope of this application. It should be noted that the rope 4 can also be replaced by a connecting rod or other structures, as long as it can drive the sleeve 3 to move stably.

[0052] In addition, such as Figure 1 As shown, in this embodiment, a mechanized construction device for socket-type PVC pipes is also provided. The device includes a sleeve 3, a rope 4, and a power component 5 as described above. Similar to the above, the inner wall of the sleeve 3 is respectively attached to the outer wall of the socket 1 and the outer wall of the spigot 2, and the outside of the sleeve is connected to the power end of the power component 5 through the rope 4, thereby driving the sleeve 3 and the socket 1 to move toward the spigot 2 so that the socket 1 and the spigot 2 are inserted into place.

[0053] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0054] The principles and implementations of the present application are described in detail with specific examples in this paper, and the above examples are only used to help understand the method of the present application and its core idea. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
