[0041] Furthermore, in the pipeline transportation and installation equipment suitable for narrow pipe corridors of the present invention, the automatic pipe holding mechanism 5 includes two first automatic connecting rods 51, two second automatic connecting rods 52, a lower pressure block 53 and two automatic rocker arms 54, one end of the two first automatic connecting rods 51 is symmetrically hinged on the bracket 41, one end of the two second automatic connecting rods 52 is respectively hinged to the other end of the two first automatic connecting rods 51, the other end of the two second automatic connecting rods 52 is respectively hinged to the two automatic rocker arms 54, the automatic rocker arms 54 are hinged to the bracket 41, and a lower pressure groove 45 is provided on the side of the bracket 41 close to the sliding base 42, and the lower pressure block 53 is installed in the lower pressure groove 45, thereby effectively ensuring that the medium and high-rise pipelines can be fixed on the bracket 41 during transportation and installation, thereby improving transportation safety.

[0042] Furthermore, in the pipeline transportation and installation equipment suitable for narrow pipe corridors of the present invention, the distance from the hinge of the rocker arm and the bracket 41 to the hinge of the second automatic connecting rod 52 is smaller than the distance from the hinge of the rocker arm and the bracket 41 to the head of the rocker arm, and the width of the lower pressure groove 45 is greater than or equal to the connection length of the two first automatic connecting rods 51, thereby effectively ensuring that the automatic rocker arm 54 can automatically hold the pipeline when the lower pressure block 53 is subjected to the gravity of the pipeline, and the head of the automatic rocker arm 54 can automatically unlock the holding state by relying on gravity when the lower pressure block 53 is not under pressure.

[0043] Furthermore, in the pipeline transportation and installation equipment suitable for narrow pipe corridors of the present invention, the hydraulic pipe holding mechanism 6 includes two hydraulic cylinders 61 and two hydraulic rocker arms 62. The two hydraulic cylinders 61 are symmetrically hinged on the installation frame 31. The two hydraulic rocker arms 62 are respectively hinged to the output ends of the two hydraulic cylinders 61. The hydraulic rocker arms 62 are hinged to the installation frame 31, thereby effectively ensuring that the low-level pipeline can be fixed on the installation frame 31 during transportation and installation, thereby improving transportation safety.

[0044] Furthermore, in the pipeline transportation and installation equipment suitable for narrow pipe corridors of the present invention, the distance from the hinge point of the hydraulic rocker arm 62 and the installation frame 31 to the hinge point of the hydraulic rocker arm 62 and the hydraulic cylinder 61 is smaller than the distance from the hinge point of the hydraulic rocker arm 62 and the installation frame 31 to the head of the hydraulic rocker arm 62, which effectively ensures the opening and closing of the hydraulic pipe holding mechanism 6.

[0045] Furthermore, in the pipeline transportation and installation equipment suitable for narrow pipe corridors of the present invention, the hydraulic cylinder 61 is connected to the oil circuit of the hydraulic system 25, thereby effectively ensuring the power supply of the hydraulic cylinder 61.

[0046] Furthermore, in the pipeline transportation and installation equipment suitable for narrow pipe corridors of the present invention, a fixing component 8 is also included, and the fixing component 8 includes a connecting pull plate 81 and a connecting pin 82. The transport frame 21, the installation frame 31 and the bracket 41 are all provided with connecting holes 9, and the connecting pin 82 matches the connecting hole 9. The transport frame 21 and the installation frame 31, and the installation frame 31 and the bracket 41 can be connected by the connecting pull plate 81, so that the transport frame 21, the installation frame 31 and the bracket 41 are connected as a whole. When not in use, the transport frame 21 is lifted off the running track 1 by the lifting cylinder 33, and the installation frame 31 is moved laterally to avoid affecting the passability of the pipe corridor.

[0047] Specifically, when transporting and installing the lower layer pipeline, there is no need to install the pipeline bracket 4. The pipeline is placed on the installation frame 31 and the hydraulic system 25 supplies energy to the hydraulic cylinder 61 to drive the hydraulic rocker arm 62 to fix the pipeline on the installation frame 31. At this time, the power device 24 drives the longitudinal wheel group 22 to transport the pipeline to the installation position along the running track 1 through the reduction motor 23. When the transport equipment 2 arrives at the installation position, the hydraulic system 25 supplies energy to the lifting cylinder 33. The lifting cylinder 33 rises to make the transverse wheel group 34 contact with the ground, and then continues to lift. In this process, each lift The lowering cylinder 33 is used in conjunction with a rigid guide column 32. The lifting cylinder 33 only bears vertical loads, while the rigid guide column 32 bears eccentric loads. At this time, the hydraulic motor 35 can drive the transverse wheel group 34 to be transported horizontally to the installation layer to the installation position. The vertical degree of freedom of the pipeline can be adjusted by adjusting the lifting cylinder 33 as a whole. The rotational degree of freedom in the transverse and longitudinal directions can be adjusted by adjusting the lifting cylinder 33 in pairs. The transverse wheel group 34 can be slightly moved forward and backward to adjust the transverse degree of freedom. The forward and backward movement of the driving wheel group can adjust the rotational degree of freedom around the vertical direction, thereby improving the installation accuracy of the pipeline;

[0048] When transporting and installing the middle and upper pipelines, the pipeline bracket 4 is stacked according to the layer height through the cooperation of the conical pin 44 and the installation slot 7, and connected to the installation frame 31. When the pipeline is placed on the bracket 41, the pipeline relies on its own weight to press the lower pressure block 53 to sink, and the first automatic connecting rod 51 and the second automatic connecting rod 52 drive the active end of the automatic rocker arm 54 to rock up and hold the pipeline tightly. At this time, the power device 24 drives the longitudinal wheel group 22 to transport the pipeline to the installation position along the running track 1 through the reduction motor 23. When the transport tool 2 arrives at the installation position, the hydraulic system 25 supplies energy to the lifting cylinder 33, and the lifting oil The cylinder 33 rises to make the transverse wheel set 34 contact the ground, and then continues to lift. At this time, the transverse wheel set 34 can be driven by the hydraulic motor 35 to be transported horizontally to the installation layer to the installation position. The vertical degree of freedom of the pipeline can be adjusted by adjusting the lifting cylinder 33 as a whole. The rotational degree of freedom in the horizontal and longitudinal directions can be adjusted by adjusting the lifting cylinders 33 in pairs. The transverse wheel set 34 can be slightly moved forward and backward to adjust the lateral degree of freedom. The driving wheel set can be moved forward and backward to adjust the rotational degree of freedom around the vertical direction. The sliding base 42 cooperates with the adjusting nut column 43 to make the longitudinal fine adjustment of the pipeline, thereby improving the installation accuracy of the pipeline.

[0049] When the pipeline does not need to be transported and installed, the transport frame 21, the installation frame 31 and the bracket 41 can be connected into one by connecting the pull plate 81 and the connecting pin 82, and the lifting cylinder 33 is lifted to lift the transport equipment 2 as a whole and move it horizontally to the designated empty space without affecting the passability of the pipeline corridor.

[0050] In summary, compared with the prior art, the pipeline transportation and installation equipment suitable for narrow pipe galleries of the present invention has the following advantages and beneficial effects:

[0051] By adopting the coordination of transport equipment and installation equipment, the transport and installation can be separated or integrated. The overall structure occupies a small space and is suitable for pipe galleries in narrow spaces. The automatic pipe holding mechanism and the hydraulic pipe holding mechanism are used to fix the pipelines, which effectively improves the safety during transportation and installation. The coordination of the lifting cylinder, the transverse wheel set and the sliding base effectively improves the installation accuracy and effectively guarantees the installation efficiency.
