[0002] A steam turbine is a rotary steam power plant that performs work by converting steam energy into mechanical energy.

[0003] In the actual assembly process, the turbine rotor and other rod-shaped components need to be transported to the upper part of the target area by traction equipment such as overhead cranes, and then lowered together with the traction equipment to complete the assembly of the rotor and other components in the target area. During the descent phase of the traction equipment, workers need to manually adjust the position of the rod-shaped components to avoid excessive assembly errors. Due to human factors, the assembly efficiency of the rod-shaped components is low. Summary of the Invention

[0008] The push-pull member is connected to the limiting member, the base is provided with a push-pull groove, the limiting member is located in the push-pull groove, and the push-pull member is used to drive the limiting member to move in the push-pull groove;

[0009] The limiting member is used to position the component to be assembled on the base.

[0010] The above technical solution has the following advantages or beneficial effects:

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Please see Figure 1 , Figure 1 This is one of the structural schematic diagrams of an assembly device provided in the embodiments of this application, such as... Figure 1 As shown, the assembly device includes:

[0019] Base 10, lifting component 20, push-pull component 30, and limiting component 40;

[0020] The lifting component 20 is disposed on the base 10, and the lifting component 20 is used to drive the base 10 to rise and fall;

[0021] The push-pull member 30 is connected to the limiting member 40. The base 10 is provided with a push-pull groove 11. The limiting member 40 is located in the push-pull groove 11. The push-pull member 30 is used to drive the limiting member 40 to move in the push-pull groove 11.

[0022] The limiting member 40 is used to place the component to be assembled on the base 10.

[0023] The assembly device provided in this application embodiment uses an automated assembly method involving lifting component 20, pushing and pulling component 30, and limiting component 40 to replace the conventional manual assembly method, thereby improving the assembly efficiency of the components to be assembled.

[0024] When the component to be assembled is confined within the limiting member 40 and the assembly device is close to the target area, the lifting member 20 first controls the base 10 to rise, so that the pushing member 30, the limiting member 40 and the component to be assembled rise together with the base 10 to a preset height; then the pushing member 30 controls the limiting member 40 to move towards the target area, so that the component to be assembled moves to the top of the target area; then the limiting member 40 is released from the position lock of the component to be assembled, and the lifting member 20 controls the base 10 to descend, so that the component to be assembled is placed in the target area.

[0025] The aforementioned components to be assembled are rod-shaped components, such as the rotor of a steam turbine or the intermediate shaft for high and low speeds. The aforementioned target area is the predetermined installation position of the components to be assembled, and the height of the predetermined installation position is lower than the aforementioned preset height. The aforementioned lifting component 20 and pushing / pushing component 30 can be electric cylinders, or they can be screw jacks and lead screws driven by motors, etc. This application embodiment does not limit them in this way.

[0026] In addition, in practical applications, the push-pull groove 11 is used to limit the position of the limiting member 40 so as to prevent the limiting member 40 from deviating in position when the push-pull member 30 controls the movement of the limiting member 40, so that the limiting member 40 can still have good stability during the movement.

[0027] Optionally, the limiting member 40 includes two parallel support arms 41. Each support arm 41 includes a straight portion 411 and a limiting portion 412 extending from the straight portion 411. The straight portion 411 and the limiting portion 412 cooperate to form a groove. A limiting block 413 is provided on the straight portion 411. The limiting block 413 is used to cooperate with the groove to place the component to be assembled on the base 10.

[0028] like Figure 2 and Figure 3 As shown, two parallel support arms 41 support and limit the two sides of the component to be assembled (i.e., the rod-shaped component) to ensure that the component to be assembled is placed stably on the limiting member 40. Each support arm 41 includes a straight part 411 and a limiting part 412. The limiting part 412 is bent or arc-shaped. The straight part 411 and the limiting part 412 cooperate to form the groove. The groove is used to place the component to be assembled. The limiting block 413 is set to further limit the component to be assembled in conjunction with the groove to ensure the safe use of the assembly device (i.e., to prevent the component to be assembled from falling out of the groove during the lifting and lowering process with the base 10).

[0029] To facilitate the placement of the component to be assembled in the tray, a telescopic groove is provided in the straight portion 411. The end of the limiting block 413 away from the tray is rotatably connected to one side of the telescopic groove, and the end of the limiting block 413 near the tray is connected to the other side of the telescopic groove by a spring. This allows the component to be assembled to roll along the extension direction of the straight portion 411 toward the position of the limiting portion 412. During the rolling process, the component to be assembled applies pressure to the limiting block 413 to press the limiting block 413 into the telescopic groove as a whole. After the component to be assembled rolls into the tray, the elastic potential energy of the spring drives the end of the limiting block 413 near the tray to extend out of the telescopic groove and abut against the component to be assembled, so as to prevent the component to be assembled from leaving the tray.

[0030] Optionally, a first rotating member 414 is provided on the limiting part 412. The rotation axis of the first rotating member 414 extends along the thickness direction of the support arm 41. A pressure member 415 is connected to the rotation axis of the first rotating member 414. The pressure member 415 rotates around the rotation axis. The pressure member 415 is used to cooperate with the bracket and the limiting block 413 to place the component to be assembled on the base 10.

[0031] Through the above settings, the position of the component to be assembled is locked by the cooperation of the tray, the limiting block 413 and the pressure member 415. The pressure member 415 is set to apply pressure to the component to be assembled toward the tray surface, so that the component to be assembled and the tray surface are pressed together, preventing the component to be assembled from passing over the obstacle of the limiting block 413 and leaving the tray under the action of inertia (referring to the process of the component to be assembled moving with the base 10 or moving with the limiting member 40).

[0032] The aforementioned pressure member 415 can be a long strip-shaped plate structure; the side of the pressure member 415 facing the groove surface is an arc surface, which can further increase the contact area between the pressure member 415 and the component to be assembled, reduce the probability that the component to be assembled will detach from the constraint of the pressure member 415 under inertia, and allow the component to be assembled to be stably placed on the limiting member 40. In practical applications, the aforementioned first rotating member 414 can be a motor.

[0033] Optionally, the limiting member 40 further includes two parallel support plates 42, the support plates 42 being located within the push-pull groove 11, the push-pull member 30 being connected to the support plates 42, and the two support plates 42 being connected to the two support arms 41 respectively.

[0034] By setting up the support plate 42, the component to be assembled can be suspended on the two support arms 41, which can reduce the probability of interference between the component to be assembled and other parts of the assembly device.

[0035] Optionally, the limiting part 412 is rotatably connected to the support plate 42, and the support plate 42 is provided with a lifting member, which is located below the flat part 411, and the flat part 411 abuts against the lifting member.

[0036] As described above, the limiting part 412 of the support arm 41 is rotatably connected to the corresponding support plate 42, and the straight part 411 of the support arm 41 is connected to the corresponding support plate 42 through the lifting member. When the component to be assembled is placed in the slot, the lifting member lifts the straight part 411 upward, so that the end of the straight part 411 away from the limiting part 412 is higher than the end of the straight part 411 close to the limiting part 412, so as to further enhance the limiting effect of the component to be assembled in the slot.

[0037] Optionally, the lifting member includes a second rotating member 431 disposed on the support plate 42. An elliptical wheel 432 is connected to the rotation axis of the second rotating member 431. The elliptical wheel 432 includes two long axis ends and two short axis ends, and the short axis ends abut against the straight portion 411.

[0038] By setting the elliptical wheel 432, while cooperating with the bracket to further enhance the limiting effect on the component to be assembled, the positional change of the straight part 411 of the support arm 41 under the action of the lifting member is reduced, so that the straight part 411 can smoothly complete the switching between the positional deviation (the position of one end of the straight part 411 is higher than the position of the other end of the straight part 411) and the positional level (the two ends of the straight part 411 are at the same horizontal height), so as to ensure the safe use of the assembly device (i.e., reduce the risk of the component to be assembled falling off the bracket).

[0039] When the major axis end of the elliptical wheel 432 abuts against the straight portion 411, the straight portion 411 is in an skewed position. When the minor axis end of the elliptical wheel 432 abuts against the straight portion 411, the straight portion 411 is in a horizontal position.

[0040] The second rotating component 431 mentioned above can also be a motor. There are two elliptical wheels 432. One elliptical wheel 432 is set on one support plate 42 and the other elliptical wheel 432 is set on another support plate 42. In order to ensure the synchronous rotation of the two elliptical wheels 432, in practical applications, it is preferable to set the two elliptical wheels 432 to be driven by the same motor. That is, the motor is installed on one of the support plates 42, and the output shaft of the motor is coaxially fixedly connected to a transmission shaft. The transmission shaft passes through the two support plates 42, and the two elliptical wheels 432 are coaxially fixedly connected to the transmission shaft.

[0041] Optionally, the lifting member includes a second rotating member 431 disposed on the support plate 42, and an eccentric wheel 433 is connected to the rotation shaft of the second rotating member 431, the eccentric wheel 433 abutting against the straight part 411.

[0042] like Figure 3 As shown, by setting the eccentric wheel 433, while cooperating with the bracket to further enhance the limiting effect on the component to be assembled, the positional change of the straight part 411 of the support arm 41 under the action of the lifting member is reduced, so that the straight part 411 can smoothly complete the state switching between position tilt and position level, thereby ensuring the safe use of the assembly device.

[0043] There are two eccentric wheels 433. The installation positions of the two eccentric wheels 433 are the same as the installation positions of the two elliptical wheels 432 mentioned above. To avoid repetition, they will not be described again.

[0044] In practice, the user can choose either the eccentric wheel 433 or the elliptical wheel 432 (in conjunction with the second rotating member 431) as the lifting member to complete the switching of the straight part 411 of the support arm 41 between the tilted position and the horizontal position. This application embodiment does not limit this.

[0045] Optionally, the assembly device further includes a distance sensor 50, which is disposed on the limiting member 40.

[0046] The distance sensor 50 is electrically connected to the push-pull member 30. During the movement of the limiting member 40 towards the target area, controlled by the push-pull member 30, the distance sensor 50 precisely controls the movement distance of the limiting member 40 and the assembly placed on it, ensuring that the assembly ultimately moves directly above the target area. The distance sensor 50 can be a displacement sensor or a position sensor, etc.

[0047] Optionally, the base 10 includes a first support portion 12 and two second support portions 13 extending from the first support portion 12. The two second support portions 13 are arranged opposite to each other. There are two push-pull grooves 11, one push-pull groove 11 is arranged on one second support portion 13 and the other push-pull groove 11 is arranged on the other second support portion 13. The push-pull member 30 is arranged on the first support portion 12.

[0048] By using two opposing second support portions 13, a gap area is formed between the two second support portions 13. During the process of the assembly device placing the component to be assembled into the target area, the existence of this gap area can reduce the probability of the assembly device colliding with other components in the target area.

[0049] In addition, such as Figure 4and Figure 5 As shown, when the components to be assembled are placed on the two second support parts 13, in order to prevent the assembly device from tilting or tipping over, multiple counterweights 60 can be arrayed on the first support part 12 to increase the weight of the first support part 12.

[0050] As mentioned above, when the second rotating component 431 is a motor, the motor can be placed on the first supporting part 12. This increases the weight of the first supporting part 12 and avoids occupying space in the second supporting part 13. In this case, a transmission rod 72 is coaxially fixedly connected to the output shaft of the motor. The transmission rod 72 passes through the two support plates 42 respectively, and both protruding ends of the transmission rod 72 are coaxially fixedly connected to the driving wheel 73. A driven wheel 74 is also provided to cooperate with the driving wheel 73 (the driving wheel 73 and the driven wheel 74 are driven by a belt), and the driven wheel 74 and the elliptical wheel 432 are coaxially fixedly connected to the linkage rod 75. When the length of a single transmission rod 72 is limited, two or more transmission rods 72 can be connected by a coupling 71 to obtain a transmission group (the length of the transmission group is greater than the distance between the two support plates 42).

[0051] Furthermore, to further enhance the structural stability of the assembly device and ensure that the limiting member 40 maintains good stability during its sliding within the push-pull groove 11, a support rod 76 is also provided between the two support plates 42. One end of the support rod 76 is fixedly connected to one of the support plates 42, and the other end of the support rod is fixedly connected to the other support plate 42.

[0052] Optionally, the base 10 is provided with a navigation component 15, a power component, and a plurality of transport wheels 14. The navigation component 15 is electrically connected to the power component, and the power component is connected to the transport wheels 14.

[0053] By using multiple transport wheels 14, the assembly unit acquires a transport function, replacing traction equipment such as overhead cranes to transport components to be assembled from the warehouse to the vicinity of the target area. In practical applications, the aforementioned transport wheels 14 can be omnidirectional wheels.

[0054] During the process of transporting the components to be assembled by the assembly device, the navigation component 15 is used to plan a transportation path from the warehouse to the target area for the assembly device, so that the power component drives the multiple transport wheels 14 to move based on the transportation path, so as to quickly complete the transportation of the components to be assembled.

[0055] The above settings can save labor costs during the transportation of components to be assembled and improve the transportation efficiency of components to be assembled.

[0056] In practical applications, the navigation component 15 can be an electronic device with navigation function, such as a magnetic navigation sensor, and the power component can be a motor.

[0057] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
