The above patent arranges support members on the inner wall of the casing body. Multiple support members in each group cooperate with each other to control the position of the pipeline passing through the floor. Multiple groups of support members cooperate with each other to make the axis of the floor-penetrating pipe parallel to the axis of the casing body, thereby ensuring that the floor-penetrating pipe is located in the middle of the reserved hole. However, the following deficiencies still exist in actual use: From a practical point of view, the friction between the support members of the device and the pipeline will affect the safety of the pipeline, and there is no corresponding operation for some uncontrollable collisions during the construction process, which may affect the safety of the pipeline.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] See also Figure 1-3 The utility model provides a pipeline construction positioning and fixing sleeve, comprising: a fixing sleeve 1, the number of the fixing sleeves 1 is two, and they are symmetrically distributed; the outer surface of one side of the upper end of the symmetrical fixing sleeve 1 is fixedly connected with a connecting piece 2, and the symmetrical connecting piece 2 is threadedly connected through a rotating shaft 4; the middle part of the inner surface of the symmetrical connecting piece 2 is fixedly connected with a symmetrical fixing piece 5, and the other end of the symmetrical fixing piece 5 is provided with a groove 501, and the symmetrical fixing piece 5 is located inside the groove 501 and a sliding device 6 is installed; the two ends of the inner surface of the symmetrical connecting piece 2 are fixedly connected with a buffer device 3.

[0022] Further as Figure 1 and Figure 2 As shown, it is worth specifically explaining that the number of the plurality of symmetrical buffer devices 3 is four, and the plurality of symmetrical buffer devices 3 all include a connecting plate 301, the rear end of the connecting plate 301 is fixedly connected to a spring 302, the other end of the spring 302 is fixedly connected to the inner surface of the fixing sleeve 1, and one side of the connecting plate 301 is fixedly connected to a spring plate 303, the other end of the spring plate 303 is fixedly connected to one side of the fixing member 5, through the plurality of buffer devices 3, that is, when the pipeline enters between two symmetrical connecting plates 301, when a pipeline in any direction changes its position angle, the pipeline in the corresponding direction will squeeze the spring 302 on the corresponding side, that is, the elastic force of the spring 302 offsets the force generated by the change in the position angle of the pipeline to a certain extent, thereby effectively improving the protection of the pipeline.

[0023] Further as Figure 1 and Figure 2 and Figure 3As shown, it is worth specifically explaining that the number of the plurality of symmetrical sliding devices 6 is four, and the plurality of symmetrical sliding devices 6 all include baffles 601, the plurality of baffles 601 all fit and are fixedly connected to the two ends of the groove 501 provided in the middle of the fixing member 5, and the middle of the plurality of symmetrical baffles 601 is fixedly connected with a connecting shaft 602, and the outer surface of the connecting shaft 602 is slidably connected with a plurality of pulleys 603, through the sliding devices 6 provided in the middle of the plurality of fixing members 5, that is, when the pipeline enters between two symmetrical fixing members 5, when the outer surface of the pipeline contacts the outer surface of the pulley 603, the pipeline is moved and the pulley 603 rotates immediately, thereby converting conventional sliding friction into rolling friction, that is, reducing friction, thereby not only saving manpower and facilitating installation, but also further improving the protection of the pipeline, and improving the safety and practicality of the positioning and fixing casing of the pipeline construction.

[0024] This solution has the following working process: when it is necessary to use the pipeline construction positioning and fixing sleeve, first, place the lower end of the pipeline construction positioning and fixing sleeve in the reserved hole, and then rotate the rotating shaft 4. The rotating shaft 4 drives the threaded connection 2 to move in the opposite direction, and then drives the fixing member 5 and the buffer device 3 to move in the opposite direction. Then put the pipeline between the fixing member 5 and the buffer device 3, and then the construction is completed. When the position angle of a pipeline in any direction changes, the pipeline in the corresponding direction will squeeze the spring 302 on the corresponding side, that is, the elastic force of the spring 302 offsets the force generated by the change in the position angle of the pipeline to a certain extent. When the pipeline enters between the two symmetrical fixing members 5, the outer surface of the pipeline contacts the outer surface of the pulley 603, the pipeline is moved, and the pulley 603 rotates immediately, thereby converting the conventional sliding friction into rolling friction, that is, reducing the friction.

[0025] According to the above working process, it can be known that: through a plurality of buffer devices 3, that is, when the pipeline enters between two symmetrical connecting plates 301, when the position angle of a pipeline in any direction changes, the pipeline in the corresponding direction will squeeze the spring 302 on the corresponding side, that is, the elastic force of the spring 302 offsets the force generated by the change in the position angle of the pipeline to a certain extent, thereby effectively improving the protection of the pipeline, and through a plurality of sliding devices 6 provided in the middle of the fixing parts 5, that is, when the pipeline enters between two symmetrical fixing parts 5, when the outer surface of the pipeline contacts the outer surface of the pulley 603, the pipeline is moved and the pulley 603 rotates immediately, thereby converting conventional sliding friction into rolling friction, that is, reducing friction, thereby not only saving manpower and facilitating installation, but also further improving the protection of the pipeline, and improving the safety and practicality of the positioning and fixing casing of the pipeline construction.

[0026] Further as Figure 2As shown, it is worth specifically explaining that the number of the plurality of symmetrical fixing members 5 and the connecting plate 301 is four, and the upper and lower ends of the plurality of symmetrical fixing members 5 and the connecting plate 301 are both rounded. By designing the upper and lower ends of the plurality of symmetrical fixing members 5 and the connecting plate 301 to be rounded, the outer surface of the pipeline can be prevented from being scratched, thereby effectively improving the protection of the pipeline.

[0027] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that a threaded hole 202 is provided in the middle of the symmetrical connecting member 2, and a nut 201 is provided at the outer end of the threaded hole 202 on one side of the connecting member 2. By rotating the rotating shaft 4 through the threaded hole 202 and the nut 201, the connecting member 2 will move in relative or opposite directions.

[0028] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the outer surfaces of the symmetrical rotation axis 4 are respectively threadedly connected to the threaded holes 202 on the fixed sleeve 1, and the outer surface of the other end of the symmetrical rotation axis 4 is fixedly connected with a fixed handle 401, which facilitates the operator to operate the rotation of the symmetrical rotation axis 4.

[0029] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the outermost ends of the plurality of pulleys 603 slightly protrude from the inner surface of the fixing member 5. Through the positional relationship between the plurality of pulleys 603 and the fixing member 5, the pipe will first contact the pulley 603. Thus, when the outer surface of the pipe contacts the outer surface of the pulley 603, the pipe is moved and the pulley 603 rotates immediately, thereby converting conventional sliding friction into rolling friction, that is, reducing friction.

[0030] In summary: when it is necessary to use the pipeline construction positioning and fixing sleeve, first, place the lower end of the pipeline construction positioning and fixing sleeve in the reserved hole, and then rotate the rotating shaft 4. The rotating shaft 4 drives the threaded connection 2 to move in the opposite direction, and then drives the fixing member 5 and the buffer device 3 to move in the opposite direction, and then put the pipeline between the fixing member 5 and the buffer device 3, and then the construction is completed. When the position angle of a pipeline in any direction changes, the pipeline in the corresponding direction will squeeze the spring 302 on the corresponding side, that is, the elastic force of the spring 302 offsets the force generated by the change in the position angle of the pipeline to a certain extent. When the pipeline enters between the two symmetrical fixing members 5, the outer surface of the pipeline contacts the outer surface of the pulley 603, and the pipeline is moved, and the pulley 603 rotates immediately. Thereby, conventional sliding friction is converted into rolling friction, that is, friction is reduced. The rounded corners of the upper and lower ends of the several symmetrical fixing members 5 and the connecting plate 301 can prevent the outer surface of the pipeline from being scratched, thereby effectively improving the protection of the pipeline. The threaded hole 202 and the nut 201 can be used to rotate the rotating shaft 4, and the connecting member 2 will move in relative or opposite directions. The fixed handle 401 facilitates the operator to operate the rotation of the symmetrical rotating shaft 4. Through the positional relationship between the several pulleys 603 and the fixing members 5, the pipeline will first contact the pulley 603. When the outer surface of the pipeline contacts the outer surface of the pulley 603, the pipeline is moved and the pulley 603 rotates immediately, thereby converting conventional sliding friction into rolling friction, that is, friction is reduced.
