Embodiment 1

[0031] Such as Figure 1-6 As shown, a metal pipe cement mortar lining machine includes a metal pipe axial installation device 1, a metal pipe lifting device 2, a rotating support wheel group 3, an auxiliary lining 4, a PLC control cabinet 17 and a cement distribution boom 16. The lining machine can automatically install and insert the metal pipe into the auxiliary liner 4 in the axial direction. The auxiliary liner 4 includes a liner 41 , a clamping part 42 , a ring body 5 and a support wheel assembly 6 . The support wheel assembly 6 includes a support roller 61 , a rotating shaft 62 , a support frame 63 , an elastic member 64 , a bearing 65 and a fastener 66 .

[0032] During and after the installation of the metal pipe 7 to the auxiliary liner 4, the support roller 61 of the support wheel assembly 6 exerts appropriate pressure on it to complete the radial positioning and ellipse calibration of the metal pipe, and the welding on the liner 41 After the metal pipe 7 is posit...

Embodiment 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 support wheel group 3, an auxiliary lining ring 4, and a PLC control cabinet? And cement placing boom 16. The lining machine realizes the automatic axial installation of the metal pipe and inserts it into the auxiliary lining 4. The auxiliary lining 4 completes the positioning, clamping, ellipse correction of the metal pipe and the improvement of the rigidity of the metal pipe. After the lining is completed, the metal pipe axis The removal of the metal pipe to the installation device 1 is automatically completed. Compared with Embodiment 1, the difference between the auxiliary bushing 4 and the auxiliary bushing 4 is that the cylinder 41 used to connect two sets of auxiliary bushings 4 is reduced, so that the auxiliary bushing 4 only includes the ring body 5 and the supporting wheel asse...

Embodiment 3

[0042] 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 support wheel group 3, an auxiliary lining 4, and a PLC control cabinet? And cement placing boom 16. The lining machine realizes the automatic installation and insertion of the metal pipe axially into the auxiliary liner 4, and the auxiliary liner 4 completes the positioning, clamping, ellipse correction of the metal pipe and the improvement of the rigidity of the metal pipe. After the lining is completed, the metal pipe axis The removal of the metal pipe to the installation device 1 is automatically completed. Compared with embodiment 1, the rotating supporting roller group 3 reduces the passive supporting roller 8 that cooperates with the rotation of the metal pipe, and only keeps the active supporting roller 9, and the auxiliary lining 4 rotates under the drive of the driving supporti...

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...
