Description

Technical Field

[0001] The utility model relates to the technical field of lining pipe traction, in particular to a traction device for lining pipe construction. Background Art

[0002] In order to prevent internal corrosion of the pipeline and prevent chemical reactions between the transported liquid and the pipeline, a material different from the pipe material is made inside the pipeline. It is called an inner liner pipe. During the installation of the inner liner pipe, a traction winch is used as the power to pull the inner liner pipe from one end of the pipeline to the other end. After the inner liner pipe is inserted, it is punched to restore it and fit tightly to the original inner wall of the pipeline. It can be seen that the traction winch is a necessary equipment in the traction installation process of the inner liner pipe.

[0003] In the actual installation of the liner pipe, due to the limited length of the pipeline, after the traction winch completes the traction of the liner pipe, the staff needs to manually cut the pipeline. During the cutting process, other cutting equipment is required, and there is a certain deviation in manual cutting. The overall operation reduces the work efficiency and also causes uneven cuts on the liner pipe. For this reason, we propose a traction device for liner pipe construction to solve the above problems.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A traction device for liner pipe construction includes a traction winch 1, a connecting rod 13 is symmetrically connected to the upper side of the traction winch 1, and the upper side of the connecting rod 13 is connected through a docking plate 2, a cylinder 3 is engaged inside the docking plate 2, and a connecting block 4 is provided at the bottom end of the cylinder 3, a cutter 5 is provided on the other side of the connecting block 4, and a support plate 6 is connected to the front of the traction winch 1.

[0023] Further, see Figure 3 and Figure 4 It can be known that a sleeve block 11 is provided on the outer side of the cylinder 3, and a support rod 12 is symmetrically connected to the outer side of the sleeve block 11. The support rod 12 is arranged in an L-shaped structure, and the bottom end of the support rod 12 is fixedly connected to the docking plate 2. When in use, the sleeve block 11 and the support rod 12 cooperate with each other to reinforce and protect the cylinder 3 to prevent the cylinder 3 from being deformed by external impact.

[0024] Further, see Figure 4 It can be seen that the connecting block 4 is configured as a U-shaped structure, and the front side of the connecting block 4 is connected to the upper side of the cutter 5 by means of screws 14. When in use, since the connecting block 4 is configured as a U-shaped structure, the cutter 5 can be inserted into the connecting block 4. By setting the screws 14, the connecting block 4 and the cutter 5 can be connected to each other, so that the staff can replace the cutter 5 that has reached the end of its service life in a timely manner.

[0025] Further, see Figure 1 and Figure 2 It can be known that a steel plate 15 is installed inside the support plate 6, an electric slide 16 is installed on the front of the traction winch 1, and the back of the support plate 6 extends into the electric slide 16. Through the arrangement of the steel plate 15, the overall structural strength of the support plate 6 can be effectively improved to prevent it from being damaged by the impact of the cutter 5. The electric slide 16 is a prior art, which is composed of a combination of a linear slide and a motor drive, wherein the motor drive is connected to the back of the support plate 6, thereby driving the support plate 6 to slide up and down, so as to support the inner liner pipe through the support plate 6, so that the inner liner pipe on the upper side of the support plate 6 is in a horizontal state, so as to achieve the effect of subsequent cutting thereof.

[0026] Further, see Figure 3 and Figure 4It can be known that a rotating block 8 is connected to the center position of the top of the connecting block 4, a driving motor 9 is installed on the lower side of the docking plate 2, and the output end of the driving motor 9 is connected to a rotating shaft 10, and the other end of the rotating shaft 10 extends into the rotating block 8, the end of the rotating shaft 10 is connected to the inner wall of the rotating block 8, and the end of the cylinder 3 is movably sleeved on the outer side of the rotating shaft 10. When in use, the rotating block 8 can be driven to rotate forward and backward through the forward and reverse driving of the driving motor 9 to realize the flipping of the cutter 5, thereby realizing the storage work of the cutter 5 and preventing the cutter 5 from always being in a vertical state.

[0027] Further, see Figure 1 and Figure 2 It can be known that the connecting rod 13 is set as an L-shaped structure, and the lower side of the connecting rod 13 is connected to the traction winch 1 through bolts.

[0028] Further, see Figure 4 It can be known that the end of the cutter 5 is connected with a snap-fit ​​block 7, and a positioning groove adapted to the snap-fit ​​block 7 is provided inside the connecting block 4. When in use, the cutter 5 can be pre-positioned through the mutual cooperation of the snap-fit ​​block 7 and the positioning groove, so that the staff can dock the connecting block 4 and the cutter 5.

[0029] Working principle: When the utility model is in use, the staff can first place the device at a suitable position, and then start the traction winch 1 to pull out the liner tube set on the outside. At this time, the staff can insert the end of the liner tube into the corresponding pipeline. When the liner tube completely penetrates the pipeline, the staff can stop the traction winch 1, and then start the electric slide 16, and then drive the support plate 6 to lift up, so that the support plate 6 contacts with the liner tube and supports the liner tube. Then the staff can start the drive motor 9 to drive the rotation The rotation of the shaft 10 can drive the rotating block 8 to rotate at the same time because the rotating block 8 is connected to the rotating shaft 10, and because the rotating block 8 is connected to the connecting block 4, the connecting block 4 can be turned over as a whole to drive the cutter 5 and the docking plate 2 to maintain a vertical state. At this time, the staff can remotely start the work of the cylinder 3, so that it drives the cutter 5 as a whole downward to achieve rapid cutting of the inner lining pipe on the upper side of the support plate 6. After the cutting is completed, the cutter 5 can be turned over again by starting the driving motor 9 in the reverse direction to achieve the storage of the cutter 5. The above is the entire working principle of the utility model.
