Description

Technical Field

[0001] The present invention relates to the technical field of hoisting in the electric power industry, and in particular to a hoisting and transporting device and method for a generator stator and a combustion engine. Background Art

[0002] The stator is the stationary part of the motor and one of the key components of the steam turbine generator. The stator consists of three parts: the stator core, the stator winding and the frame. For high-voltage and large-capacity synchronous motors, a rotating magnetic pole structure is used. Since the capacity and voltage of the excitation part are often much smaller than the armature, the armature is installed on the stator and the main magnetic pole is installed on the rotor. The generator stator mainly acts on the rotating magnetic field formed by the rotor to cut the magnetic field to generate voltage;

[0003] A Chinese patent with publication number CN201825672U discloses a generator stator hoisting device, which uses an advanced combined hoisting frame and a hydraulic lifting device to hoist the generator stator, effectively improving the safety of hoisting and the convenience of installation and disassembly;

[0004] However, in the actual use process, after the stator is lifted to the stator base, it cannot be placed in the installation direction. The only way is to re-arrange the steering beam and hook above the lifting frame, and then control the hydraulic lifting device to lift the stator again and turn it in the stator installation direction. The operation steps are numerous and the process is complicated, which reduces the efficiency of lifting;

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] The object of the present invention is to provide a hoisting and transporting device and method for generator stators and fuel turbines. By setting a guide component, the generator stator can be hoisted to the stator by using a lower hoisting frame, an upper hoisting frame and a pair of mobile transporters, and the installation direction of the generator stator can be directly adjusted by using the movement and displacement of two groups of mobile transporters, thereby saving the installation personnel the step of rearranging and measuring the hooks.

A connecting hole is provided on the upper surface of the hoisting plate near the two ends, and guide rails are provided on both sides of the connecting hole. A second mobile transporter is provided between two groups of guide rails corresponding to the same connecting hole, and the lower end of the second mobile transporter passes through the connecting hole and is connected to a connecting piece, the lower end of the connecting piece is connected to a hook, a measuring instrument is provided on the upper outer surface of the hoisting plate at a position corresponding to the two groups of second mobile transporters, and the measuring instrument is connected to an electrical signal of a control panel, the control panel is connected to an external controller, and the staff inputs the required offset angle value X1 of the generator stator through the controller before transportation;

[0010] The control panel includes a data acquisition module, a data processing module and a control module;

[0011] The data acquisition module is used to collect the offset coordinates of the two groups of mobile transporters 2 from the standard point and transmit the data to the data processing module;

[0012] After receiving the above data, the data processing module obtains the real-time offset angle X2 of the generator stator through processing and transmits it to the control module;

[0013] After receiving the real-time offset angle of the generator stator, the control module compares it with X1. When X1=X2, the control module controls the second mobile transporter to stop working.

[0014] Furthermore, the connecting member includes a connecting block 1, a connecting block 2, a fixed shaft, a gear and a rack, the connecting block 1 is fixedly connected to the mobile transporter 2, and the bottom end of the connecting block 1 passes through the interior of the connecting hole and is fixedly connected to the connecting block 2, the lower end of the connecting block 2 is provided with a connecting groove, and a bearing is provided on the inner surface of the connecting groove near the bottom end, the inner surface of the bearing is fixedly connected to the fixed shaft, and the top end of the fixed shaft is located inside the connecting groove and is fixedly connected to the gear, and the bottom end of the fixed shaft is fixedly connected to the hook.

[0017] Furthermore, the real-time offset angle processing method of the generator stator is:

[0018] Before transporting, the staff inputs the required offset angle value X1 of the generator stator through the controller, and then uses the upper hoisting frame, the lower hoisting frame and the mobile transporter 1 to transport the generator stator to the specified position. At this time, if the angle of the generator stator needs to be adjusted, the control panel is used to adjust one or two groups of mobile transporters 2 as needed to move in the direction of the required offset angle value, wherein the Y-axis coordinate of the measuring instrument along the direction parallel to the connecting hole is set to the standard point, and the Y-axis offset coordinates of the front and rear two groups of mobile transporters 2 from the standard point are set to L1 and L2 respectively, and the vertical spacing of the two groups of connecting holes is set to L3. According to the fitting formula: The real-time offset angle X2 of the generator stator is obtained.

[0020] Step 1: Before transporting, the staff inputs the required offset angle value X1 of the generator stator through the controller, and then uses the upper hoisting frame, the lower hoisting frame and the mobile transporter to transport the generator stator to the designated location;

[0021] Step 2: If the angle of the generator stator needs to be adjusted at this time, one or two groups of mobile transporters 2 are adjusted to work according to the needs through the control panel, so that they move in the direction of the required offset angle value, wherein the Y-axis coordinate of the measuring instrument along the direction parallel to the connecting hole is set to the standard point, and the Y-axis offset coordinates of the front and rear groups of mobile transporters 2 from the standard point are set to L1 and L2 respectively, and the vertical spacing of the two groups of connecting holes is set to L3.

When X2=X1, the control module controls the second mobile transporter to stop working, and uses the upper hoisting frame and the lower hoisting frame to move the generator stator to the specified position;

[0022] Step 3: When the two groups of mobile transporters 2 move synchronously at the same time, the generator stator device can be controlled to move forward and backward along the axial direction perpendicular to the generator stator, thereby increasing the application range of the device;

[0023] Step 4. When the connecting block 1 moves inside the connecting hole along with the mobile transporter 2, the connecting block 2 drives the hook to move, and at this time, the connecting block 2 drives the gear to move along the rack direction. Since the gear and the rack are meshed with each other, during the movement of the connecting block 2, the gear drives the fixed shaft and the hook to rotate along the rotation direction of the generator stator, thereby reducing the torsional force on the steel rope 2 during the movement of the corresponding mobile transporter 2.

A second mobile transporter 111 is provided between two groups of guide rails 113 corresponding to the same connecting hole 81, and the lower end of the second mobile transporter 111 passes through the connecting hole 81 and is connected to the connecting piece 12. The lower end of the connecting piece 12 is connected to the hook 9. A measuring instrument 112 for measuring the offset coordinates of the second mobile transporter 111 corresponding to the two groups of second mobile transporters 111 is provided on the upper outer surface of the hoisting plate 8 at a position corresponding to the two groups of second mobile transporters 111, and the measuring instrument 112 is connected to the control panel 10 by electrical signals, and the control panel 10 is connected to the external controller. The staff inputs the required offset angle value X1 of the generator stator 5 through the controller before transportation;

[0037] The control panel 10 includes a data acquisition module, a data processing module and a control module; the data acquisition module is used to collect the offset coordinates of the two groups of mobile transporters 111 from the standard point and transmit the data to the data processing module; after receiving the above data, the data processing module obtains the real-time offset angle X2 of the generator stator 5 through processing and transmits it to the control module; when the angle of the generator stator 5 needs to be adjusted, the control panel 10 is used to adjust one or two groups of mobile transporters 111 as needed to move in the direction of the required offset angle value, wherein the Y-axis coordinate of the measuring instrument 112 along the direction parallel to the connecting hole 81 is set to the standard point, the Y-axis offset coordinates of the front and rear two groups of mobile transporters 111 from the standard point are set to L1 and L2 respectively, and the vertical spacing of the two groups of connecting holes 81 is set to L3, according to the fitting formula: The real-time offset angle X2 of the generator stator 5 is obtained. When X2=X1, the control module controls the second mobile transporter 111 to stop working, and uses the upper hanging frame 2 and the lower hanging frame 1 to move the generator stator 5 to a designated position.

[0038] Embodiment 2:

[0039] In the first embodiment, when the two sets of mobile transporters 111 move asynchronously, the steel strand 13 will generate a large twisting force on the hook 9 and itself due to the overall movement of the hook 9 and the connecting member 12. Long-term use will reduce the service life of the steel strand 13 and the hook 9. Therefore, by providing the connecting member 12, the hook 9 can rotate synchronously with the steel strand 13 along the rotation direction of the generator stator 5, thereby reducing the steel strand 13 in the corresponding mobile transporter 111. The twisting force received during the movement ensures the service life of the steel rope 13 and the hook 9. The connecting member 12 includes a connecting block 121, a connecting block 122, a fixed shaft 123, a gear 124 and a rack 125. The connecting block 121 is fixedly connected to the mobile transporter 111. The mobile transporter 111 drives the connecting block 121 to move, and the bottom end of the connecting block 121 penetrates the inside of the connecting hole 81 and is fixedly connected with the connecting block 122. The lower end of the connecting block 122 is opened. A connecting groove 126 is provided, and a bearing 127 is provided on the inner surface of the connecting groove 126 near the bottom end, and a fixed shaft 123 is fixedly connected to the inner surface of the bearing 127, and the top end of the fixed shaft 123 is located inside the connecting groove 126 and fixedly connected to a gear 124, and the bottom end of the fixed shaft 123 is fixedly connected to the hook 9; a rack 125 is fixedly connected to the inner side of the connecting hole 81, and the rack 125 passes through the connecting block 122, and the rack 125 and the gear 124 mesh with each other. The gear 124 rotates simultaneously with the movement of the fixed shaft 123. The two sides of the connecting block 122 are fixedly connected with the limiting blocks 128, and the connecting hole 81 and the limiting groove 129 are provided at the corresponding position of the limiting block 128 to increase the support force of the connecting block 122. The limiting block 128 is slidably connected with the limiting groove 129. The surfaces of the limiting block 128 and the limiting groove 129 are both provided with a polytetrafluoroethylene coating, which can reduce the friction between the limiting block 128 and the limiting groove 129.

[0040] When the two sets of mobile transporters 111 move synchronously at the same time, the generator stator 5 device can be controlled to move forward and backward along the axial direction perpendicular to the generator stator 5, thereby increasing the application range of the device;

[0041] When the connecting block 121 moves inside the connecting hole 81 along with the mobile transporter 2 111, the connecting block 122 drives the hook 9 to move, and at this time, the connecting block 122 drives the gear 124 to move along the direction of the rack 125. Since the gear 124 and the rack 125 are meshed with each other, during the process of moving along with the connecting block 122, the gear 124 drives the fixed shaft 123 and the hook 9 to rotate along the rotation direction of the generator stator 5.

[0042] The working principle of the present invention is as follows: before transportation, the staff inputs the required offset angle value X1 of the generator stator 5 through the controller, and then uses the upper hoisting frame 2 and the lower hoisting frame 1 and the mobile transporter 1 3 to transport the generator stator 5 to the specified position. At this time, if the angle of the generator stator 5 needs to be adjusted, the control panel 10 is used to adjust one or two groups of mobile transporters 111 to work as needed, so that it moves in the direction of the required offset angle value, wherein the Y-axis coordinate of the measuring instrument 112 along the direction of the parallel connecting hole 81 is set to the standard point, and the Y-axis offset coordinates of the front and rear groups of mobile transporters 111 from the standard point are set to L1 and L2 respectively, and the vertical spacing of the two groups of connecting holes 81 is set to L3. According to the fitting formula: the real-time offset angle X2 of the generator stator 5 is obtained. When X2=X1, the control module controls the mobile transporter 111 to stop working, and uses the upper hoisting frame 2 and the lower hoisting frame 1 to move the generator stator 5 to the specified position;

[0043] When the two sets of mobile transporters 111 move synchronously at the same time, the generator stator 5 device can be controlled to move forward and backward along the axial direction perpendicular to the generator stator 5, thereby increasing the application range of the device;

[0044] When the connecting block 121 moves inside the connecting hole 81 along with the mobile transporter 2 111, the connecting block 122 drives the hook 9 to move, and at this time, the connecting block 122 drives the gear 124 to move along the direction of the rack 125. Since the gear 124 and the rack 125 are meshed with each other, during the process of moving along with the connecting block 122, the gear 124 drives the fixed shaft 123 and the hook 9 to rotate along the rotation direction of the generator stator 5.
