Example Embodiment

[0030] Example 1

[0031] Such as Figure 1-6 As shown, a metal tube cement mortar lining machine includes a metal tube axial installation device 1, a metal tube lifting device 2, a rotating supporting wheel set 3, an auxiliary liner 4, a PLC control cabinet 17 and a cement placing boom 16. The lining machine can realize the automatic axial installation and insertion of the metal pipe into the auxiliary lining cylinder 4. The auxiliary liner 4 includes a liner 41, a clamping member 42, a ring body 5 and a supporting wheel assembly 6. The supporting wheel assembly 6 includes a supporting roller 61, a rotating shaft 62, a supporting frame 63, an elastic member 64, a bearing 65 and a fastener 66.

[0032] During and after the installation of the metal tube 7 to the auxiliary liner 4, the supporting roller 61 of the supporting wheel assembly 6 applies appropriate pressure to it to complete the radial positioning and elliptical rounding of the metal tube, and weld it to the liner 41 ...

Example Embodiment

[0038] Example 2

[0039] Such as Figure 1-6 As shown, in this embodiment, a metal pipe cement mortar lining machine includes a metal pipe axial installation device 1, a metal pipe lifting device 2, a rotating roller set 3, an auxiliary lining ring 4, and a PLC control cabinet? And cement placing boom 16. The lining machine realizes that the metal pipe is automatically installed and inserted into the auxiliary liner 4 in the axial direction. The auxiliary liner 4 completes the positioning, clamping, ellipse correction and improvement of the rigidity of the metal pipe. After the lining is completed, the metal pipe axis The disassembly of the metal pipe to the installation device 1 is automatically completed. Compared with Embodiment 1, the difference between the auxiliary liner 4 and the auxiliary liner 4 is that the cylinder 41 for connecting two sets of auxiliary liners 4 is reduced, so that the auxiliary liner 4 only includes the ring body 5 and the support wheel assembly 6...

[0041] Example 3

[0042] Such as Figure 1-6 As shown, in this embodiment, a metal tube cement mortar lining machine includes a metal tube axial installation device 1, a metal tube lifting device 2, a rotating roller set 3, an auxiliary lining cylinder 4, and a PLC control cabinet? And cement placing boom 16. The lining machine realizes that the metal pipe is automatically installed and inserted into the auxiliary liner 4 in the axial direction. The auxiliary liner 4 completes the positioning, clamping, ellipse correction and improvement of the rigidity of the metal pipe. After the lining is completed, the metal pipe axis The disassembly of the metal pipe to the installation device 1 is automatically completed. Compared with the first embodiment, the rotating supporting wheel set 3 reduces the passive supporting wheel 8 that cooperates with the rotating action of the metal tube, and only the active supporting wheel 9 is retained, and the auxiliary ring 4 is rotated under the d...

Abstract

The invention discloses a metal pipe cement mortar lining machine, and relates to the technical field of metal pipe manufacturing. The metal pipe cement mortar lining machine comprises a metal pipe axial installing device, a metal pipe lifting device, rotary supporting roller sets, auxiliary lining cylinders and a PLC control cabinet. The metal pipe axial installing device is located above the metal pipe lifting device, the rotary supporting roller sets are arranged on the left side of the metal pipe axial installing device, the auxiliary lining cylinders are located between the two rotary supporting roller sets and the metal pipe axial installing device, the metal pipe lifting device and the rotary supporting roller sets are controlled by the PLC control cabinet. When the lining machine is used for conducting metal pipe inner wall cement mortar lining operation, the lining machine is especially high in adaptability of the ovality of a thin-wall metal pipe, and the metal pipe cement mortar lining machine has the advantages of being convenient to use, high in automation degree and the like.

Description

technical field [0001] The invention relates to the technical field of metal pipe manufacturing, in particular to a metal pipe cement mortar lining machine. Background technique [0002] At present, there are various forms of cement mortar lining equipment for linear metal pipes. The technological process is cement mortar cloth and centrifugal compaction. Cement mortar distributing methods are as follows: 1. The cement mortar is basically evenly stored in the bottom of the inner cavity of the horizontally placed metal pipe along the axial direction; 2. The mud mortar is basically evenly sprayed on the inner wall of the metal pipe by spraying; 3. The cement mortar is basically Apply evenly on the inner wall of the metal pipe. The cement lining coating is realized by the friction and centrifugal force between the inner wall of the metal pipe and the cement mortar generated by the rotation of the metal pipe, and the leveling of the cement mortar. The cement lining is compacte...
