Description

Technical Field

[0001] The invention relates to a turning device which can be used as a main drive of a shield machine with a super large diameter. Background Art

[0002] The main drive is an inseparable and heaviest component in the shield machine, and its unit value is also relatively high. From the perspective of ensuring the installation quality of the main drive, it is very important to be able to simply, quickly and safely realize the installation of the main drive. In the previous main drive assembly and installation operations, the main drive needs to be turned over at least three times. For these three turning operations, three sets of independent turning devices were designed in the past, corresponding to different occasions and turning operations. Although this method can realize the hoisting and turning operations of the main drive of the super-large diameter shield machine, the turning device is not universal for the above three turning operations. In addition, for main drives of different thicknesses and diameters, the turning device is often not universal. The turning of the main drive is only used during installation and disassembly.

The cylinder connecting vertical plate 132 is obliquely arranged on the cylinder connecting base plate 131.

[0050] See attached Figure 6 To Attachment Fig.11 As shown, the plate assembly includes a C-shaped plate 21, an L-shaped plate 22, an I-shaped plate 23, an H-shaped steel beam 24, and a cutter disc rotating ring pad 25. The C-shaped plate 21 includes a first horizontal plate 211 and a second horizontal plate 212 arranged parallel to each other, and a first vertical plate 213 fixedly connected between the first horizontal plate 211 and the second horizontal plate 212.

[0051] Specifically, see Appendix Figure 6 As shown, the C-shaped plate 21 includes a C-shaped upper plate 21a and a C-shaped lower plate 21b. The first vertical plate 213 of the C-shaped lower plate 21b further has a first arc protrusion 2131, and the first arc protrusion 2131 is located on the outer side of the C-shaped lower plate 21b; see the attached Figure 7 As shown, the L-shaped plate 22 includes an L-shaped upper plate 22a and an L-shaped lower plate 22b.

[0052] As shown in the accompanying drawings, the connecting plate assembly 112, the first horizontal plate 211, the second horizontal plate 212, the third horizontal plate 221 and the I-type plate 23 are all provided with a first connecting hole group 113, the connecting vertical plate 132 and the second vertical plate 222 are all provided with a second connecting hole group 133, the C-type plate 21, the L-type plate 22 and the H-type steel beam 24 are all provided with a third connecting hole group 241, the C-type plate 21, the L-type plate 22 and the I-type plate 23 are all provided with lifting holes 214, and the cutter disc rotating ring pad 25 is provided with a plurality of cutter disc connecting holes 114. In this way, not only the versatility of the lifting ear assembly and the plate assembly is improved, but also the design difficulty of the turning device is reduced, thereby saving design costs.

[0053] Specifically, the first connection hole group 113 includes a pin connection hole 1131 and a plurality of first splicing holes 1132. When the lifting ear assembly and the plate assembly are connected, the center lines of the pin connection hole 1131 on the lifting ear assembly and the pin connection hole 1131 on the plate assembly coincide with each other, and the first splicing hole 1132 on the lifting ear assembly and the first splicing hole 1132 on the plate assembly correspond to each other. The second connection hole group 133 includes a pin connection hole 1131 and a plurality of second splicing holes 1331. When the oil cylinder mounting ring lifting ear 13 and the L-shaped plate 22 are connected to each other, When the C-shaped plate / L-shaped plate 22 is connected to the H-shaped steel beam 24, the center lines of the pin connecting hole 1131 on the cylinder mounting ring ear 13 and the pin connecting hole 1131 on the L-shaped plate 22 coincide with each other, and the second splicing hole 1331 on the cylinder mounting ring ear 13 and the second splicing hole 1331 on the L-shaped plate 22 correspond one to one; the third connecting hole group 241 includes a plurality of third splicing holes 2411. When the C-shaped plate / L-shaped plate 22 and the H-shaped steel beam 24 are connected to each other, the third splicing holes 2411 on the H-shaped steel beam 24 and the third splicing holes 2411 on the C-shaped plate / L-shaped plate 22 correspond one to one.

[0054] See attached Figure 1 To Attachment Figure 3 As shown, the connecting plate assembly 112 includes a first connecting plate 1121 and a second connecting plate 1122 arranged parallel to each other, at least one of the first connecting plate 1121 and the second connecting plate 1122 has a first connecting hole group 113, the first connecting plate 1121 and the second connecting plate 1122 are both provided with pin connecting holes 1131, the center lines of the pin connecting holes 1131 on the first connecting plate 1121 and the second connecting plate 1122 coincide, and there is a gap between the first connecting plate 1121 and the second connecting plate 1122, and the width of the gap is the same as the thickness of the C-shaped plate 21, the L-shaped plate 22, and the I-shaped plate 23. In this way, when installing the turning device, it can be ensured that the components are closely matched and will not shake.

[0055] See attached Fig. 9 and attached Fig.10 As shown, the H-shaped steel beam 24 extends along its own length direction, and the cross-section of the H-shaped steel beam is H-shaped. There are fixing plates 242 at both ends of the H-shaped steel beam 24. The third connection hole group 241 is opened on the fixing plate 242. The H-shaped steel beam 24 is provided with multiple groups of different lengths. When the diameter of the main drive changes, it is only necessary to replace the H-shaped steel beams of different lengths without the need for redesign and production.

[0056] See attached Fig.11As shown, the cutter disc rotating ring gasket 25 is installed between the ring surface of the cutter disc rotating ring 32 and the cutter disc connecting base plate 111. The cutter disc rotating ring gasket 25 has multiple groups, and the thicknesses of the multiple groups of cutter disc rotating ring gaskets 25 are different. In this way, when the thickness of the main drive changes, the number of cutter disc rotating ring gaskets 25 can be added / reduced between the cutter disc rotating ring 32 and the cutter disc connecting base plate 111, thereby further improving the versatility of the turning device.

[0057] The drive box 31 has a drive box ear connection hole (not shown in the figure) on the annular surface. In the present embodiment, the arrangement of the drive box connection holes 122 on the drive box connection base plate 121 is the same as the cutter disc rotating ring ear connection holes; the cutter disc rotating ring 32 has a cutter disc rotating ring ear connection hole (not shown in the figure) on the annular surface. In the present embodiment, the cutter disc connection holes 114 on the cutter disc connection base plate 111 are arranged in the same manner as the cutter disc rotating ring ear connection holes; the cylinder mounting ring 33 has a mounting plane (not shown in the figure) on the outer cylindrical surface, and the mounting plane is provided with a cylinder mounting ring ear connection hole (not shown in the figure). In the present embodiment, the cylinder connection holes 134 on the cylinder connection base plate 131 are arranged in the same manner as the cylinder mounting ring ear connection holes.

[0058] See attached Fig.11 To Attachment Fig. 20 As shown, the turning device has three usage states, including the turning state in the factory, the light turning state and the turning state on the construction site. In the same project, when the main drive is turned over three times, the ear assembly and the plate assembly can be combined to form three turning devices, and there is no need to separately design and produce three sets of corresponding turning devices, so that the versatility of the ear assembly and the plate assembly can be achieved; and in different projects, it is only necessary to adjust the length and shape of the cutter head connecting base plate 111, the drive box connecting base plate 121 and the cylinder connecting base plate 131, thereby reducing the production cost of the turning device.

[0059] See attached Fig.12 , Attachment Fig.16 and attached Fig.17 As shown, when the turning device is in the turning state in the factory, the cutter head rotating ring ear 11 is detachably mounted on the cutter head rotating ring 32 ring surface, and the I-shaped plate 23 is detachably mounted on the cutter head rotating ring ear 11.

Specifically, four groups of cutter disc rotating ring lifting ears 11 are arranged along the circumference of the cutter disc rotating ring 32, and four groups of cylinder mounting ring lifting ears 13 are arranged along the circumference of the cylinder mounting ring 33. The arrangement of the cylinder mounting ring lifting ears 13 is the same as the arrangement of the cutter disc rotating ring lifting ears 11. Two of the four groups of cutter disc rotating ring lifting ears 11 are detachably connected with I-type plates 23. The two groups of cutter disc rotating ring lifting ears 11 installed with I-type plates 23 and the other two groups of cutter disc rotating ring lifting ears 11 are centrally symmetrically distributed relative to the rotation center of the cutter disc rotating ring 32. The two groups of I-type plates 23 are parallel to each other, and the center lines of the lifting holes 214 on the two groups of I-type plates 23 coincide.

[0060] When the turning device is in the state of turning over in the factory, two groups of turning pin shaft assemblies 331 and two groups of turning frames (not shown in the figure) are installed on the outer cylindrical surface of the cylinder mounting ring 33. The two groups of turning pin shaft assemblies 331 are located at both ends of a certain diameter of the cylinder mounting ring 33. Each group of turning pin shaft assemblies 331 has a turning pin shaft (not shown in the figure). The axis lines of the two groups of turning pin shafts coincide. The two groups of cutter disc rotating ears 11 with I-shaped plates 23 installed and the other two groups are symmetrically distributed about the axis lines of the turning pin shafts. The turning pin shaft assembly and the turning frame are rotatably connected. The cylinder mounting ring 33 is located between the two groups of turning frames. The cutter disc rotating ring 32 is embedded in the drive box 31. The drive box 31 and the cylinder mounting ring 33 are detachably connected. The rotation centers of the cutter disc rotating ring 32, the drive box 31 and the cylinder mounting ring 33 coincide, and the cylinder mounting ring 33 is located at the bottom. When the drive box 31, the cutter disc rotating ring 32 and the cylinder mounting ring 33 need to be turned over, the main hook (not shown in the figure) hooks the lifting hole 214 on the I-plate, and the auxiliary hook (not shown in the figure) hooks the pin shaft connecting hole 1131 on the cylinder mounting ring 33. The turning over can be achieved by coordinating the forces between the main hook and the auxiliary hook.

The cutter disc rotating ring 32 is embedded in the drive box 31, and the rotation center of the cutter disc rotating ring 32 coincides with the rotation center of the drive box 31, and the cutter disc rotating ring 32 is located on the upper side of the drive box 31. The C-shaped plate 21 is connected between the cutter disc rotating ring ear 11 and the drive box ear 12, and the H-shaped steel beam 24 is connected to the C-shaped plate 21.

[0062] Specifically, four groups of cutter disc rotating ring ears 11 are arranged along the circumference of the cutter disc rotating ring 32, and four groups of drive box ears 12 are arranged along the circumference of the drive box 31. The arrangement of the drive box ears 12 is the same as the arrangement of the cutter disc rotating ring ears 11. The C-shaped plate 21 is provided with four groups parallel to each other, two groups of which are C-shaped upper plates 21a arranged parallel to each other, and the other two groups are C-shaped lower plates 21b arranged parallel to each other. Multiple groups of H-shaped steel beams 24 are detachably installed between the two groups of C-shaped upper plates 21a, and multiple groups of H-shaped steel beams 24 are detachably installed between the two groups of C-shaped lower plates 21b.

[0063] During the turning over process, a hook (not shown in the figure) is hooked on the lifting hole 214 on the C-shaped upper plate 21a, and the first arc protrusions 2131 of the two sets of C-shaped lower plates 21b are supported on the ground. Turning over can be achieved by adjusting the force of the hook. Such a setting not only facilitates turning over, but also reduces the impact generated during the turning over process.

[0065] Specifically, four groups of cutter disc rotating ring ears 11 are arranged along the circumference of the cutter disc rotating ring 32, and four groups of cylinder mounting ring ears 13 are arranged along the circumference of the outer cylindrical surface of the cylinder mounting ring 33.

The L-shaped plate 22 is provided with four groups parallel to each other, two groups of which are L-shaped upper plates 22a arranged in parallel to each other, and the other two groups are L-shaped lower plates 22b arranged in parallel to each other. The third horizontal plate 221 of the L-shaped plate 22 and the connecting plate assembly 112 on the cutter disc rotating ring ear 11 are detachably connected, the second vertical plate 222 of the L-shaped plate 22 and the connecting vertical plate 132 on the cylinder mounting ring ear 13 are detachably connected, and multiple groups of H-shaped steel beams 24 are detachably connected between the two groups of L-shaped upper plates 22a, and multiple groups of H-shaped steel beams are detachably installed between the two groups of L-shaped lower plates 22b.

[0066] During the turning process, the hook (not shown in the figure) is hooked on the lifting hole 214 on the L-shaped upper plate 22a, and the second arc protrusions 2221 of the two sets of L-shaped lower plates 22b are supported on the ground. The turning can be achieved by adjusting the force of the hook. This arrangement is not only convenient for turning, but also can reduce the impact generated during the turning process. Since the ring surface of the cylinder mounting ring 33 is equipped with an oil cylinder, this turning only requires adjusting the ring surface of the cutter head rotating ring 32 and the cylinder mounting ring 33 from the horizontal direction to the vertical direction.

[0067] The turning device of the present invention has a plurality of combination modes of its lifting ear assembly and plate assembly, which can be suitable for turning over the main drive in different occasions, thereby improving the versatility of the turning device. When the diameter of the main drive changes, only the lifting ear assembly needs to be adjusted, thereby reducing the cost of the turning device. Moreover, by increasing / decreasing the number of the cutter disc rotating ring pads 25 between the annular surface of the cutter disc rotating ring 32 and the cutter disc rotating ring lifting ear 11, it can also adapt to changes in the thickness of the main drive, thereby further improving the versatility of the turning device.
