Description

Technical Field

[0001] This utility model relates to the field of steam turbine maintenance technology, and in particular to a hydraulic motor support device. Background Technology

[0002] Nuclear power turbines are equipped with several valves, such as main steam valves, main control valves, reheat main steam valves, and reheat main control valves. Each valve is equipped with a hydraulic actuator to control its opening. The main components of the hydraulic actuator are a small but powerful hydraulic cylinder and an integrated block for controlling the direction of hydraulic oil. The cylinder is a single-acting cylinder. Under the action of high-pressure hydraulic oil, the hydraulic actuator provides the force to open the valve, and under the action of a spring, it provides the reaction force to close the valve. Therefore, the hydraulic actuator is an important component of nuclear power turbines.

[0003] To ensure the stable performance of the hydraulic actuator, regular preventative disassembly and maintenance are necessary. This mainly involves removing the hydraulic actuator's servo valve, solenoid valve, unloading valve, filter, check valve, inlet valve, and orifice plate for maintenance, replacing O-rings in relevant locations, and finally reassembling and performing minimum operating tests, trial runs, internal leakage tests, pressure tests, external leakage tests, and full-stroke tests. Disassembly and maintenance are highly specialized and usually require transporting the hydraulic actuator to the manufacturer. This necessitates handling and transporting the hydraulic actuator. Current technology typically involves placing the hydraulic actuator directly on the vehicle and securing it simply, but this positioning method has low reliability and makes it difficult to guarantee the stability of the hydraulic actuator's position during transportation.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] In existing technologies, the hydraulic actuator is usually placed directly on the vehicle and simply fixed in place. However, this positioning method has low reliability and it is difficult to ensure the stability of the hydraulic actuator's position during transportation.

[0032] In response to this problem, this embodiment provides a hydraulic motor support device to solve the above-mentioned issues.

[0033] Please refer to Figure 1 The hydraulic motor support device includes a base 1, a first support structure 2, and a second support structure 3. The first support structure 2 is fixedly installed on the base 1, and the first support structure 2 includes supports along a first direction (e.g., ...). Figure 1 A first support block 21 and a second support block 22 are spaced apart (in the direction indicated by the middle arrow ab). The first support block 21 has a first support surface 211, and the second support block 22 has a second support surface 221. Both the first support surface 211 and the second support surface 221 are used to fit against the outer surface of the hydraulic motor. A second support structure 3 is fixedly installed on the base 1. The second support structure 3 and the first support structure 2 are aligned along a second direction (e.g., as indicated by the middle arrow ab). Figure 1 The second support structure 3 includes a third support block 31, which has a third support surface 311. Along the first direction, the third support block 31 is located between the first support block 21 and the second support block 22. The third support block 31 is positioned relative to the base 1 along a third direction (e.g., as indicated by the middle arrow cd). Figure 1 The position (in the direction indicated by the middle arrow ef) is adjustable. The third support surface 311 is used to fit against the outer surface of the oil motor. The first direction, the second direction and the third direction are perpendicular to each other.

[0034] The motor support device provided in this embodiment supports the cylinder of the hydraulic motor through the first support structure 2 and the second support structure 3, and when the hydraulic motor is supported, the axis of the hydraulic motor extends along the second direction.

[0035] Specifically, the first support structure 2 and the second support structure 3 support the cylinder of the hydraulic motor at intervals along the second direction. The first support block 21 and the second support block 22 in the first support structure 2 support two positions on the outer surface of the cylinder of the hydraulic motor, and the third support block 31 in the second support structure 3 supports one position on the outer surface of the cylinder of the hydraulic motor, thereby forming multi-point support. Furthermore, the support positions of the first support block 21 and the second support block 22 on the hydraulic motor are distributed along the circumferential direction of the hydraulic motor, which can ensure the relative position stability of the hydraulic motor and the base 1, thereby improving the positional stability of the hydraulic motor during transportation.

[0036] In this embodiment, the first support block 21 and the second support block 22 are separately configured. This reduces the contact area between the first support structure 2 and the oil motor while ensuring the stability of the support for the oil motor, making it easier to manufacture and effectively reducing costs. Of course, in other embodiments, the first support block 21 and the second support block 22 can be made into one piece as needed. However, this would increase the contact area between the first support structure 2 and the oil motor, thereby increasing the manufacturing difficulty and production costs.

[0037] Optionally, the second support structure 3 also includes a stud 32 fixedly connected to the third support block 31, and a support seat 33 fixedly connected to the base 1, with the stud 32 and the support seat 33 threadedly connected. With this configuration, the height of the third support block 31 can be adjusted by turning the stud 32 to accommodate different support height requirements for the cylinder of the hydraulic motor.

[0038] In other embodiments, the third support block 31 can also be slidably connected to the base 1, and several pin holes are provided on the third support block 31 along the third direction. By passing a pin through one of the pin holes and inserting it into the base 1, the relative position of the third support block 31 and the base 1 along the third direction can also be adjusted.

[0039] Optionally, the first support surface 211, the second support surface 221, and the third support surface 311 are all arc surfaces, and the radii of the first support surface 211 and the second support surface 221 are equal and concentrically arranged. It is understood that the outer surface of the cylinder of the hydraulic actuator is a cylindrical surface, and setting the first support surface 211, the second support surface 221, and the third support surface 311 as arc surfaces can effectively fit against the outer surface of the cylinder of the hydraulic actuator to ensure the stability of the hydraulic actuator support.

[0040] Optionally, the first support block 21 and the second support block 22 are symmetrically arranged about the third support block 31 along a first direction. With this arrangement, the third support surface 311 of the third support block 31 will support the lowest part of the cylinder of the hydraulic motor. Since the third support surface 311 is an arc surface, it inherently possesses a certain anti-rotation function. Combined with the first support surface 211 of the first support block 21 and the second support surface 221 of the second support block 22, which support the cylinder of the hydraulic motor from both sides along the first direction, the stability of the hydraulic motor support can be effectively guaranteed.

[0041] Optionally, the hydraulic motor support device includes multiple first support structures 2. Along the second direction, the multiple first support structures 2 are all located on one side of the second support structure 3, and are arranged at intervals along the second direction. This arrangement, by supporting the cylinder block of the hydraulic motor with multiple first support structures 2, can further improve the stability of the hydraulic motor support effect. In this embodiment, an example of a hydraulic motor support device including two first support structures 2 is provided. In other embodiments, the number of first support structures 2 can be selected according to actual needs.

[0042] Optionally, the first support structure 2 further includes a first connecting block 23 and a second connecting block 24. The first connecting block 23 is fixedly connected to the first support block 21, and the second connecting block 24 is fixedly connected to the second support block 22. Both the first connecting block 23 and the second connecting block 24 are fixedly connected to the base 1. This arrangement facilitates assembly. Preferably, the first connecting block 23 is fixed to both the first support block 21 and the base 1 by welding, and the second connecting block 24 is also fixed to both the second support block 22 and the base 1 by welding.

[0043] Optionally, the first support structure 2 further includes a first reinforcing block 25 fixedly connected to the first connecting block 23 and the base 1, and a second reinforcing block 26 fixedly connected to the second connecting block 24 and the base 1. This configuration strengthens the connection between the first connecting block 23 and the base 1 through the first reinforcing block 25, and strengthens the connection between the second connecting block 24 and the base 1 through the second reinforcing block 26. In this embodiment, the first reinforcing block 25 is welded to both the first connecting block 23 and the base 1, and the second reinforcing block 26 is welded to both the second connecting block 24 and the base 1.

[0044] Optionally, the hydraulic motor support device further includes a plurality of lifting lugs 4 fixedly disposed on the base 1. The lifting lugs 4 are used for hoisting the hydraulic motor support device and can also be used in conjunction with ropes to further secure the hydraulic motor supported on the hydraulic motor support device. In this embodiment, an example of six lifting lugs 4 is provided. In other embodiments, the number of lifting lugs 4 can be set according to actual needs.

[0045] Optionally, the base 1 includes two parallel and spaced-apart longitudinal beams 11, and two transverse beams 12 connected between the two longitudinal beams 11. The two longitudinal beams 11 are spaced apart along a first direction, and the transverse beams 12 are spaced apart along a second direction. A first support structure 2 and a second support structure 3 are respectively installed on the two transverse beams 12. This configuration makes the structure of the base 1 simple and its weight low. In other embodiments, the base 1 can also be replaced by a steel plate, etc.

[0046] Optionally, the base 1 further includes a reinforcing beam 13 connecting the two longitudinal beams 11, with the reinforcing beam 13 located between the two transverse beams 12. This arrangement further enhances the structural strength of the base 1. In this embodiment, one of the two first support structures 2 is mounted on one of the transverse beams 12, and the other is mounted on the reinforcing beam 13.

[0047] In this embodiment, the number of reinforcing beams 13 is specifically one. In other embodiments, the number of reinforcing beams 13 can also be set to two or more as needed.

[0048] Optionally, the longitudinal beam 11, the transverse beam 12, and the reinforcing beam 13 are all made of channel steel. This arrangement allows the longitudinal beam 11, the transverse beam 12, and the reinforcing beam 13 to be made of profiles, which is convenient for processing and has a lower cost. In other embodiments, the longitudinal beam 11, the transverse beam 12, and the reinforcing beam 13 can also be made of square steel or I-beams, etc.

[0049] The method of using this hydraulic motor support device is as follows:

[0050] Step 1: Remove the hydraulic actuator from the steam turbine;

[0051] Step 2: Connect the lifting device's slings to the lifting lug 4 on the hydraulic motor support device, and use the lifting device to lift the hydraulic motor support device onto the transport vehicle.

[0052] Step 3: Adjust the height of the third support block 31 according to the size of the hydraulic motor;

[0053] Step 4: Hoist the removed hydraulic motor onto the hydraulic motor support device, and support it through the first support structure 2 and the second support structure 3;

[0054] Step 5: Secure the hydraulic motor further by threading the rope through the hole in lug 4.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
