[0047] like Figure 1 As shown in the embodiment of this application, the turbine rotor pivot bearing mounting device includes a chassis 100. On the side of the chassis 100 used to support the turbine rotor, from one end of the chassis 100 to the other end, the chassis 100 is sequentially provided with a locking assembly 130, a first support assembly 140, a first mounting assembly 150, a second support assembly 160, a second mounting assembly 170, and a third support assembly 180.
[0048] The locking assembly 130 is used to axially lock the turbine rotor shaft.
[0049] The first support assembly 140, the second support assembly 160 and the third support assembly 180 are all used to support the rotating shaft of the turbine rotor;
[0050] Both the first mounting component 150 and the second mounting component 170 are used to mount torque multipliers;
[0051] An installation station is provided between the second support component 160 and the second mounting component 170, the installation station being used to accommodate the pivot bearing.
[0052] like Figure 1 As shown, Figure 1 This is a top view of the turbine rotor pivot bearing mounting device, wherein the chassis 100 can be a frame structure, such as... Figure 1 The rectangular frame shape shown is as follows. Specifically, it can be formed by the first load-bearing rod 110, the second load-bearing rod 111, the third load-bearing rod 112, and the fourth load-bearing rod 113 connected end to end, forming a rectangular frame. Figure 1 In the directions shown, the left and right directions are the length directions of the chassis 100, and the up and down directions are the width directions of the chassis 100. In order to increase the sturdiness of the chassis 100, reinforcing bars can be set inside the rectangular frame formed by the four load-bearing bars, in the length and / or width directions of the chassis 100. The reinforcing bars can be connected to the load-bearing bars. The technical solution of this application does not impose specific restrictions on the specific location and number of reinforcing bars.
[0053] Continue to refer to Figure 1 During installation, the length direction of the turbine rotor is aligned with the length direction of the chassis 100. Along the length direction of the chassis 100, from one end to the other, the chassis 100 is sequentially equipped with a locking assembly 130, a first support assembly 140, a first mounting assembly 150, a second support assembly 160, a second mounting assembly 170, and a third support assembly 180. When the chassis 100 is placed horizontally on the ground, the locking assembly 130, the first support assembly 140, the first mounting assembly 150, the second support assembly 160, the second mounting assembly 170, and the third support assembly 180 are all located on the upward-facing side of the chassis 100.
[0054] Continue to refer to Figure 1 , Figure 2 ,exist Figure 1 In the indicated orientation, the locking assembly 130 is located at the left end of the chassis 100. The locking assembly 130 is used to match the splined end of the turbine rotor shaft. For example, a sleeve tooth 137 can be provided on the locking assembly 130. The sleeve tooth 137 matches the spline, so that when the turbine rotor shaft is placed on the chassis 100, the sleeve tooth 137 matches the spline, which can fix the turbine rotor shaft in its circumferential direction and prevent the turbine rotor shaft from rotating along its axis during the installation of the pivot bearing.
[0055] Continue to refer to Figure 1 ,exist Figure 1In the indicated orientation, the first support assembly 140 is located to the right of the locking assembly 130, with a gap between the first support assembly 140 and the locking assembly 130. The first mounting assembly 150 is located to the right of the first support assembly 140, with a gap between the first mounting assembly 150 and the first support assembly 140. The second support assembly 160 is located to the right of the first mounting assembly 150, with a gap between the second support assembly 160 and the first mounting assembly 150. The second mounting assembly 170 is located to the right of the second support assembly 160, with a gap between the second support assembly 160 and the second mounting assembly 170. The third support assembly 180 is located at the right end of the chassis 100. When installing the pivot bearing onto the turbine rotor shaft, the chassis 100 is placed horizontally on the ground. Figure 1 In the indicated orientation, the spline at the left end of the turbine rotor shaft matches the sleeve 137 of the locking assembly 130. The first support assembly 140 supports the left end of the turbine rotor shaft, the second support assembly 160 supports the middle part of the turbine rotor shaft, and the third support assembly 180 supports the right end of the turbine rotor shaft. Two pivot bearings are located between the second support assembly 160 and the second mounting assembly 170, i.e., at the mounting position between the second support assembly 160 and the second mounting assembly 170. The first mounting assembly 150 is used to install the torque multiplier. When in use, it is used with a corresponding torque wrench to install the pivot bearing on the left side. The second mounting assembly 170 is also used to install the torque multiplier. When in use, it is used with a corresponding torque wrench to install the pivot bearing on the right side. The torque multiplier is installed after the first mounting assembly 160 and the second mounting assembly 170. During installation, the output end of the torque multiplier is matched with the fastening nut of the pivot bearing, and a torque wrench or electric wrench is installed at the input end of the torque multiplier. The torque wrench or electric wrench can be used to lock the corresponding pivot bearing through the torque multiplier.
[0056] Additionally, it should be noted that the heights of the locking assembly 130, the first support assembly 140, the second support assembly 160, and the third support assembly 180 need to be matched. Matching heights means that the turbine rotor shaft can remain horizontal after being mounted on the locking assembly 130, the first support assembly 140, the second support assembly 160, and the third support assembly 180.
[0057] The turbine rotor pivot bearing mounting device in this embodiment supports the turbine rotor shaft from different positions by setting a first support component 140, a second support component 160, and a third support component 180. The locking component 130 ensures that the turbine rotor shaft does not rotate around its axis. The first mounting component 150 and the second mounting component 170 for mounting torque multipliers are provided. The two pivot bearings can be installed by means of torque multipliers that correspond to the two positions of the two pivot bearings respectively. There is no need to flip the turbine rotor during the installation process, and the turbine rotor is placed on the chassis 100 and will not fall off. Compared with the existing installation method based on lifting tools and slings, it is safer and more convenient.
[0058] like Figure 2 As shown, Figure 2 for Figure 1 In the cross-sectional view of AA in the present application embodiment, the locking assembly 130 includes: a fixing frame 131, one end of the fixing frame 131 is disposed on the chassis 100, and the other end is away from the chassis 100;
[0059] A sleeve tooth 137 is disposed at one end of the fixing frame 131 away from the chassis 100, and the sleeve tooth 137 is used to match the spline of the turbine rotor shaft.
[0060] The lower end of the fixing frame 131 is mounted on the chassis 100. For example, the fixing frame 131 can be directly mounted on the first load-bearing rod 110 of the chassis 100. Alternatively, a reinforcing rod can be installed between the second load-bearing rod 111 and the fourth load-bearing rod 113, and the lower end of the fixing frame 131 can be mounted on the reinforcing rod. Figure 1 As shown, a first reinforcing rod 120 is provided between the second load-bearing rod 111 and the fourth load-bearing rod 113, and a fixing frame 131 is provided on the first reinforcing rod 120.
[0061] Continue to refer to Figure 2 In this embodiment of the application, the fixing frame 131 includes:
[0062] A first fixing rod 132 and a second fixing rod 133 are arranged in parallel. The same end of the first fixing rod 132 and the second fixing rod 133 are fixedly connected to the chassis 100. The other ends of the first fixing rod 132 and the second fixing rod 133 extend away from the chassis 100. The end of the first fixing rod 132 away from the chassis 100 and the end of the second fixing rod 133 away from the chassis 100 are provided with a receiving groove 134. The sleeve tooth 137 is fixed in the receiving groove 134.
[0063] The first inclined rod 135 has one end fixedly connected to the upper end of the first fixed rod 132 and the other end connected to the chassis 100. The first inclined rod 135 and the first fixed rod 132 are set at an angle.
[0064] The second inclined rod 136 has one end fixedly connected to the upper end of the second fixed rod 133 and the other end connected to the chassis 100. The second inclined rod 136 and the second fixed rod 133 are set at an angle.
[0065] like Figure 2 As shown, the lower ends of the first fixing rod 132 and the second fixing rod 133 are fixedly connected to the first reinforcing rod 120. Both the first fixing rod 132 and the second fixing rod 133 extend upward perpendicularly to the first reinforcing rod 120. The upper ends of the first fixing rod 132 and the upper ends of the second fixing rod 133 together form a receiving groove 134. The upper end of the first inclined rod 135 is connected to the upper end of the first fixing rod 132, and the lower end is connected to the first reinforcing rod 120. The first inclined rod 135, the first fixing rod 132, and the portion of the first reinforcing rod 120 between the first fixing rod 132 and the first inclined rod 135 form a triangular stable structure. The upper end of the second inclined rod 136 is connected to the upper end of the second fixing rod 133, and the lower end is connected to the first reinforcing rod 120. The second inclined rod 136, the second fixing rod 133, and the portion of the first reinforcing rod 120 between the second fixing rod 133 and the second inclined rod 136 form a triangular stable structure.
[0066] In one embodiment, the outer contour of the sleeve tooth 137 is hexagonal, and the receiving groove 134 can be configured as a hexagon that conforms to the outer contour of the sleeve tooth 137. When the sleeve tooth 137 is installed in the receiving groove 134, the outer contour of the sleeve tooth 137 fits against the inner sidewall of the receiving groove 134. Since both the sleeve tooth 137 and the receiving groove 134 are hexagonal, it is ensured that the sleeve tooth 137 will not rotate within the receiving groove 134. Consequently, when the spline of the turbine rotor shaft meshes with the teeth on the inner side of the sleeve tooth 137, it is ensured that the turbine rotor shaft will not rotate. In other embodiments, the receiving groove 134 can also be configured as having two parallel straight surfaces. During installation, the two parallel straight surfaces fit against the two outer sidewalls of the hexagonal sleeve tooth 137, which also serves to fix the sleeve tooth 137. It should be noted that the receiving groove 134 and the sleeve tooth 137 can also be pentagonal, quadrilateral, or other irregular circles in other embodiments. This application does not limit the specific shape of the sleeve tooth 137 and the receiving groove 134. Figure 3 As shown, Figure 3 for Figure 1 A cross-sectional view of BB in the image. In this embodiment of the application, the first support component 140 includes:
[0067] A first support rod 141 and a second support rod 142 are arranged in parallel. The same end of the first support rod 141 and the second support rod 142 are fixedly connected to the chassis 100, and the other end of the first support rod 141 and the second support rod 142 are far away from the chassis 100.
[0068] A first annular clamp 143 is connected to one end of the first support rod 141 away from the chassis 100 and one end of the second support rod 142 away from the chassis 100. The first annular clamp 143 is used to accommodate the shaft of the turbine rotor.
[0069] In this embodiment of the application, a second reinforcing rod 121 may be provided between the second load-bearing rod 111 and the fourth load-bearing rod 113 of the chassis 100. The second reinforcing rod 121 is perpendicular to both the second load-bearing rod 111 and the fourth load-bearing rod 113. The first support component 140 may be provided on the second reinforcing rod 121. In addition, the first support assembly 140 may include a first support rod 141 and a second support rod 142. The lower end of the first support rod 141 is disposed on the second reinforcing rod 121, and the other end extends vertically upward. The lower end of the second support rod 142 is disposed on the second reinforcing rod 121, and the other end extends vertically upward. The upper ends of the first support rod 141 and the second support rod 142 are provided with a first annular clamp 143. During installation, the turbine rotor shaft is disposed within the first annular clamp 143. The first annular clamp 143 can not only support the turbine rotor shaft in the vertical direction, but also prevent the turbine rotor from moving axially after the first annular clamp 143 clamps the turbine rotor shaft, thus ensuring the stability of the turbine rotor during installation.
[0070] like Figure 4 As shown, Figure 4 for Figure 1 A cross-sectional view of CC in the image. In this embodiment of the application, the first mounting component 150 includes:
[0071] A first mounting rod 151, one end of which is disposed on the chassis 100, and the other end of which extends away from the chassis 100. A first mounting hole 152 is provided at the end of the first mounting rod 151 away from the chassis 100.
[0072] The second mounting rod 153 has one end disposed on the chassis 100 and the other end extending away from the chassis 100. The end of the second mounting rod 153 away from the chassis is provided with a second mounting hole 154.
[0073] The first mounting hole 152 and the second mounting hole 154 are used to mount the torque multiplier.
[0074] In this embodiment, one end of the first mounting rod 151 is connected to the first load-bearing rod 110, and the other end extends upward and is provided with a first mounting hole 152. One end of the second mounting rod 153 is connected to the fourth load-bearing rod 113, and the other end extends upward and is provided with a second mounting hole 154. The first mounting rod 151 and the second mounting rod 153 have the same length. The torque multiplier is installed on the first mounting hole 152 and the second mounting hole 154. The first mounting hole 152 and the second mounting hole 154 together install a torque multiplier.
[0075] Continue to refer to Figure 4 In this embodiment of the application, the first mounting rod 151 is disposed at one end of the chassis 100 and rotatably connected to the chassis 100, and the second mounting rod 153 is disposed at one end of the chassis 100 and rotatably connected to the chassis 100. Both the first mounting rod 151 and the second mounting rod 153 rotate along the width direction of the chassis 100.
[0076] One end of the first mounting rod 151 is rotatably connected to the second load-bearing rod 111 of the chassis 100, while the other end is a free end. Figure 1 In the indicated orientation, the plane containing the sweep path of the first mounting rod 151 during rotation is a cross-section along the width of the chassis 100, i.e., the section containing CC. One end of the second mounting rod 153 is rotatably connected to the fourth load-bearing rod 113 of the chassis 100, while the other end is a free end. Figure 1 In the indicated orientation, the plane containing the sweep path of the second mounting rod 153 during rotation is the cross-section in the width direction of the chassis 100, i.e., the section containing CC. When the first mounting rod 151 and the second mounting rod 153 rotate toward the chassis 100, i.e., in... Figure 4 In this orientation, the first mounting rod 151 rotates clockwise and the second mounting rod 153 rotates counterclockwise, freeing up space to facilitate the mounting of the turbine rotor shaft onto the chassis 100; when the first mounting rod 151 and the second mounting rod 153 rotate in a direction away from the chassis 100, that is, in Figure 4 In the orientation, the first mounting rod 151 is rotated counterclockwise to the appropriate position, and the second mounting rod 153 is rotated clockwise to the appropriate position, so that the torque multiplier can be installed based on the first mounting hole 152 and the second mounting hole 154.
[0077] like Figure 1As shown in the embodiment of this application, the first mounting rod 151 is disposed at one end of the chassis 100 and is slidably connected to the chassis 100 along the length direction of the chassis 100. The second mounting rod 153 is disposed at one end of the chassis 100 and is slidably connected to the chassis 100 along the length direction of the chassis 100. The sliding directions of the first mounting rod 151 and the second mounting rod 153 are parallel to the axial direction of the turbine rotor.
[0078] In this embodiment, a first slider 155 can be provided on the first load-bearing rod 110. The first slider 155 can slide along the length direction of the second load-bearing rod 111. A first mounting rod 151 is provided on the first slider 155. The first mounting rod 151 can also be rotatably connected to the first slider. The plane on which the first mounting rod 151 sweeps when it rotates is... Figure 1 In the indicated orientation, the cross-section of the chassis 100 in the width direction; a second slider 156 can be installed on the fourth load-bearing rod 113, the second slider 156 can slide along the length direction of the fourth load-bearing rod 113, and a second mounting rod 153 is installed on the second slider 156. The second mounting rod 153 can also be rotatably connected to the second slider, and the plane of the sweep path of the second mounting rod 153 when it rotates is... Figure 1 The cross-section of the chassis 100 in the width direction is shown in the diagram. Therefore, the first mounting rod 151 and the second mounting rod 153 can not only rotate to release the mounting space, but also slide along the length of the chassis 100, making operation more flexible.
[0079] like Figure 5 As shown, Figure 5 for Figure 1 A cross-sectional view of DD- in this embodiment of the application shows that the second support component 160 includes:
[0080] The third support rod 161 has one end rotatably connected to the chassis 100 and rotates along the length of the chassis 100. The other end of the third support rod 161 is provided with an arc-shaped support groove 162 for accommodating the rotating shaft of the turbine rotor.
[0081] In this embodiment, a third reinforcing rod 122 is provided between the second supporting rod 111 and the fourth supporting rod 113. The third reinforcing rod is perpendicular to both the second supporting rod 111 and the fourth supporting rod 113. One end of the third support rod 161 is mounted on the third reinforcing rod 122 and is rotatably connected to it. The plane of the sweep path of the third reinforcing rod 122 during rotation is [plane missing]. Figure 1In the indicated orientation, the cross-section along the length of the chassis 100 shows an arc-shaped support groove 162 at the end of the third support rod 161 furthest from the third reinforcing rod 122. During installation, the turbine rotor's shaft is located within the arc-shaped support groove 162. After the fulcrum bearing is installed, the turbine rotor is raised, and the third support rod 161 is rotated towards the side closer to the chassis 100 to free up space, facilitating the removal of the turbine rotor.
[0082] like Figure 6 As shown in this embodiment, the second mounting component 170 includes:
[0083] The third mounting rod 171 has one end on the chassis 100 and the other end has a third mounting hole 172.
[0084] The fourth mounting rod 173 has one end on the chassis 100 and the other end has a fourth mounting hole 174.
[0085] The third mounting hole 172 and the fourth mounting hole 174 are used to mount the torque multiplier.
[0086] In this embodiment, a fourth reinforcing rod 123 is provided between the second load-bearing rod 111 and the fourth load-bearing rod 113. The fourth reinforcing rod 123 is perpendicular to both the second load-bearing rod 111 and the fourth load-bearing rod 113. One end of the third mounting rod 171 is connected to the fourth reinforcing rod 123, and the other end extends vertically upward and is provided with a third mounting hole 172. One end of the fourth mounting rod 173 is connected to the fourth reinforcing rod 123, and the other end extends vertically upward and is provided with a fourth mounting hole 174. The third mounting rod 171 and the fourth mounting rod 173 have the same length. The third mounting hole 172 and the fourth mounting hole 174 are used to install a torque multiplier. It should be noted that the third mounting hole 172 and the fourth mounting hole 174 are used to install a single torque multiplier.
[0087] like Figure 1 As shown in this embodiment, the third support component 180 includes:
[0088] The fourth support rod 181 is rotatably connected to the chassis 100 at one end and rotates along the length of the chassis 100. The other end of the fourth support rod 181 is provided with a second annular clamp 182, which is used to accommodate the rotating shaft of the turbine rotor.
[0089] Among them, one end of the fourth support rod 181 is rotatably connected to the fourth reinforcing rod 123, and the other end is a free end. The plane in which the sweep path of the fourth support rod 181 rotates is [missing information]. Figure 1In the cross-section along the length of the chassis 100 in the indicated orientation, the free end of the fourth support rod 181 is provided with a second annular clamp 182. In use, the fourth support rod 181 is rotated to be perpendicular to the fourth reinforcing rod 123, and the turbine rotor's shaft is positioned within the second annular clamp 182. The second annular clamp 182 not only provides vertical support for the turbine rotor's shaft but also prevents axial movement of the turbine rotor after clamping it, ensuring the stability of the turbine rotor during installation. After the fulcrum bearing is installed, the second annular clamp 182 is opened, and the fourth support rod 181 is rotated towards the chassis 100 to release space, facilitating the removal of the turbine rotor.
[0090] In this embodiment of the application, buffer pads may also be provided in the first annular clamp 143, the second annular clamp 182 and the arc-shaped support groove 162 to protect the turbine rotor shaft.
[0091] In this embodiment of the application, rollers may also be provided at the bottom of the chassis 100 for easy movement.
[0092] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
