Technical Field

[0001] This utility model relates to the technical field of hydropower station unit maintenance equipment, and in particular to a bridge crane paralleling device. Background Technology

[0002] During the installation and subsequent maintenance of hydropower station generating units, when it is necessary to lift the generator rotor, the rotor is extremely heavy and bulky. Therefore, it is essential to connect two cranes in parallel to facilitate the lifting operation. In standard operating procedures, the cranes use both electrical and mechanical connections to ensure that the two cranes maintain synchronized positions when operating in parallel. Typically, the mechanical connection is achieved through mechanical linkages between the two cranes.

[0003] For example, patent CN216038278U discloses a novel bridge crane paralleling connecting rod installation device. The connecting rod is placed on a fixed pulley and pushed towards the gap between the main beams of the two bridge cranes, so that the connecting rod is placed in the groove of the base of the two bridge cranes. The upper clamping plate is then fastened onto the base, and the fixing bolts are tightened to clamp the connecting rod, completing the paralleling of the two bridge cranes. However, this device requires manual handling of the connecting rod during paralleling, and the considerable weight of the connecting rod makes the operation difficult, especially in high-altitude, edge-prone environments, where this operation method has a relatively high risk factor. Utility Model Content

[0014] More preferably, it also includes a control mechanism, which is electrically connected to both the bridge crane and the fixing mechanism. Sensors are provided on both the first mating surface and the second mating surface, and the sensors are electrically connected to the control mechanism.

[0015] Based on the above technical solutions, preferably, both the first movable end and the second movable end are provided with flexible components.

[0016] Based on the above technical solution, preferably, there are two detachable components, which are respectively disposed on the first connector and the second connector.

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0034] like Figures 1 to 8As shown, this utility model provides a bridge crane paralleling device, which includes a positioning mechanism 1 and a fixing mechanism 2. The positioning mechanism 1 includes a first positioning member 11 and a second positioning member 12, which are respectively disposed on two bridge cranes 4. The first positioning member 11 and the second positioning member 12 are correspondingly disposed and respectively disposed on one side of the two bridge cranes 4 facing each other. The fixing mechanism 2 includes a first connecting member 21, a second connecting member 22 and a detachable component 23. The first connecting member 21 is disposed on the first positioning member 11, the second connecting member 22 is disposed on the second positioning member 12, and the detachable component 23 connects the first connecting member 21 and the second connecting member 22 through plug-in engagement, snap-fit ​​engagement or clamping engagement.

[0035] The bridge crane paralleling device is used for paralleling operations when multiple bridge cranes 4 are operating in conjunction. It is installed on the bridge crane 4. The corresponding arrangement of the first positioning component 11 and the second positioning component 12 provides a positioning reference for the paralleling of bridge cranes 4. The detachable component 23 connects the first connecting component 21 and the second connecting component 22 through plug-in, snap-fit, or clamping engagement, so that the first connecting component 21 and the second connecting component 22 are stably connected. The detachable connection method is not only convenient to operate, but also provides a firm connection, which can meet the stability of the bridge crane 4 in parallel operation and the flexibility during disassembly, effectively adapting to the usage needs of different scenarios. This device significantly reduces the need for operators, especially avoiding the risks and inconveniences of working at heights or on dangerous edges, greatly improving the safety and efficiency of operations.

[0036] Optionally, the positioning mechanism 1 is located at the end of the main beam of the bridge crane 4. The end of the main beam of the bridge crane 4 has relatively high structural strength and rigidity, and can withstand the weight of the merging device and the additional forces generated during merging. Installing the merging device at the end can make full use of the structural strength of the main beam end and ensure the stability of the device during operation. Of course, in different application scenarios, the positioning mechanism 1 can also be located at other positions on the main beam of the bridge crane 4, or at other positions on the bridge crane 4.

[0037] In some embodiments, the first connecting member 21 is a through hole formed in the first positioning member 11, and the second connecting member 22 is a through hole formed in the second positioning member 12. The first connecting member 21 and the second connecting member 22 are correspondingly arranged. The detachable component 23 includes a driving member 231 disposed on the first positioning member 11 or the second positioning member 12. The movable end of the driving member 231 is provided with a plug-in member 232, which is used to plug into the through hole. The driving member 231 is used to drive the movement of the plug-in member 232, inserting the plug-in member 232 into the through hole to achieve a quick plug-in connection. The plug-in connection structure is simple to operate, easy to implement, and has high stability after connection. It can effectively prevent the bridge crane 4 from loosening or falling off during parallel operation, significantly improving the safety and reliability of the parallel operation device.

[0038] The detachable component 23 can be disposed on either the first positioning member 11 or the second positioning member 12. For example, if the detachable component 23 is disposed on the first positioning member 11, the first connecting member 21 is a through hole extending through the first positioning member 11, and the second connecting member 22 is a blind hole extending through the second positioning member 12; similarly, if the detachable component 23 is disposed on the second positioning member 12, the second connecting member 22 is a through hole extending through the second positioning member 12, and the first connecting member 21 is a blind hole extending through the first positioning member 11. The component 232 is then connected to the first connecting member 21 and the second connecting member 22 via a movable insertion.

[0039] Optionally, the driving component 231 includes a hydraulic driver and an electric driver. In this embodiment, the driving component 231 is a driving cylinder. The piston rod of the driving cylinder is connected to the plug-in component 232 to drive the reciprocating movement of the plug-in component 232.

[0040] The first positioning member 11 and the second positioning member 12 are arranged vertically correspondingly, or the first positioning member 11 and the second positioning member 12 are arranged side by side. The opening direction of the through hole is adaptively opened according to the corresponding position of the first positioning member 11 and the second positioning member 12, thereby ensuring the stability and reliability of the connection between the first positioning member 11 and the second positioning member 12 after the connector 232 is inserted into the through hole.

[0041] like Figures 1 to 8As shown, in some embodiments, the positioning mechanism 1 further includes a first rotating component 13 and a second rotating component 14. The first rotating component 13 and the second rotating component 14 are respectively disposed on the two bridge cranes 4. The first positioning element 11 is disposed on the rotating end of the first rotating component 13, and the second positioning element 12 is disposed on the rotating end of the second rotating component 14. The first rotating component 13 is used to adjust the swing angle of the first positioning element 11, and the second rotating component 14 is used to adjust the swing angle of the second positioning element 12. Thus, even if there is an angular deviation in the initial position of the bridge crane 4, the first positioning element 11 and the second positioning element 12 can be quickly aligned by adjusting the first rotating component 13 and the second rotating component 14, further improving the flexibility and adaptability of parallel operation and reducing the requirements for the initial position accuracy of the bridge crane 4.

[0042] Optionally, the first positioning member 11 and the second positioning member 12 rotate in the same plane, and the rotation directions of the first positioning member 11 and the second positioning member 12 are opposite.

[0043] Furthermore, when the bridge cranes 4 do not need to be paralleled, the first positioning member 11 and the second positioning member 12 can be rotated and stored in the side of the bridge crane 4, reducing the space occupied by the bridge crane 4 and facilitating operation. For example, taking the direction of the two bridge cranes 4 side-by-side as the width direction, when the bridge cranes 4 do not need to be paralleled, the first positioning member 11 and the second positioning member 12 are extended along the length direction by rotation and stored in the side of the bridge crane 4. When paralleling is required, the first positioning member 11 and the second positioning member 12 are extended along the width direction by rotation to cooperate with each other for parallel connection.

[0044] The first rotating component 13 and the second rotating component 14 can be driven to rotate using any structure, such as a motor or a rotary cylinder. The structures of the first rotating component 13 and the second rotating component 14 can be the same or different. In this embodiment, both the first rotating component 13 and the second rotating component 14 are motors. Of course, in different application scenarios, the first rotating component 13 and the second rotating component 14 may also include a transmission component for transmission connection. The transmission component can be a mechanism such as a linkage, a gear set, or a pulley.

[0045] In some embodiments, the positioning mechanism 1 further includes a first mounting base 15 and a second mounting base 16, which are respectively disposed on two bridge cranes 4, and the opposing sides of the first mounting base 15 and the second mounting base 16 are respectively a first mating surface 151 and a second mating surface 161; the first positioning member 11 is disposed on the first mounting base 15, and the first movable end 111 of the first positioning member 11 corresponds to the first mating surface 151; the second positioning member 12 is disposed on the second mounting base 16, and the second movable end 121 of the second positioning member 12 corresponds to the second mating surface 161. The first mating surface 151 and the second mating surface 161 can further limit the range of motion of the first positioning member 11 and the second positioning member 12, ensuring their stability during operation, thereby improving the reliability of the entire positioning mechanism 1 and providing a more reliable positioning guarantee for the parallel operation of the bridge cranes 4.

[0046] like Figures 1 to 8 As shown, in some embodiments, the bridge crane paralleling device further includes a control mechanism, which is electrically connected to both the bridge crane 4 and the fixing mechanism 2. Sensors 3 are installed on both the first mating surface 151 and the second mating surface 161, and are electrically connected to the control mechanism. The sensors 3 can monitor the relative position and distance between the first mating surface 151 and the second mating surface 161 in real time and feed the data back to the control mechanism. Based on this information, the control mechanism precisely controls the movement of the bridge crane 4 and the operation of the fixing mechanism 2, achieving an automated paralleling process, thereby improving paralleling efficiency and accuracy, and reducing errors and risks associated with manual operation.

[0047] Optionally, the sensor 3 includes a contact sensor or a pressure sensor, used to measure whether the first swing end and the second swing end are in contact with the second mounting base 16 and the first mounting base 15, and whether they are in position.

[0048] In some embodiments, both the first swing end and the second swing end are provided with a flexible member 17. The flexible member 17 can absorb impact force when they come into contact with each other, avoid hard collisions, thereby reducing wear, extending service life, and improving the smoothness of the paralleling process.

[0049] In some embodiments, the detachable component 23 connects the first connector 21 and the second connector 22 via a snap-fit ​​engagement. The detachable component 23 includes a hook and a ring, one of which is disposed on the first connector 21 and the other on the second connector 22. The hook engages with the ring, thus achieving a fixed connection between the first positioning component 11 and the second positioning component 12.

[0050] Of course, the detachable component 23 can also adopt a James coupler structure. Two detachable components 23 are provided, respectively disposed on the first connector 21 and the second connector 22. Each detachable component 23 includes a drop pin 233, a hook tongue 234, and a connecting pin 235. The hook tongue 234 is rotatably mounted on the first connector 21 or the second connector 22 via the connecting pin 235. The drop pin 233 is used to lock the hook tongue 234. Through the cooperation of the hook tongue 234 with the first connector 21 or the second connector 22 and the locking of the drop pin 233, the connection's firmness can be ensured, effectively preventing loosening or detachment even under complex working conditions, significantly improving the reliability of the paralleling device.

[0051] Optionally, both the first connector 21 and the second connector 22 have a cavity 236 on opposite sides, and the detachable component 23 is correspondingly disposed within the cavity 236. The cavity 236 serves to protect the detachable component 23, preventing it from being interfered with or damaged by external forces during operation, resulting in a more aesthetically pleasing appearance and facilitating maintenance and repair.

[0052] In some embodiments, the detachable component 23 connects the first connecting member 21 and the second connecting member 22 through a clamping engagement. The detachable component 23 includes a gripper disposed on the first positioning member 11 or the second positioning member 12, the gripper being used to clamp and fix the first positioning member 11 and the second positioning member 12. Alternatively, the detachable component 23 may also include a robotic arm disposed on the first positioning member 11 or the second positioning member 12, the robotic arm being used to clamp and fix the first positioning member 11 and the second positioning member 12. The opening and closing of the gripper or the robotic arm allows for quick and easy fixing of the first positioning member 11 and the second positioning member 12 together, with simple and fast operation. Furthermore, the clamping force can be adjusted as needed, further improving the applicability and flexibility of the paralleling device and meeting users' needs for speed and convenience in paralleling operations.

[0053] like Figures 1 to 8As shown above, the bridge crane paralleling device provided in this application controls the extension directions of the first positioning member 11 and the second positioning member 12 to be parallel to the bridge crane 4 when paralleling is not required. When paralleling is required, the first rotating member 13 and the second rotating member 14 drive the first positioning member 11 and the second positioning member 12 to rotate from the direction parallel to the bridge crane 4 to the vertical direction, respectively. Then, the two bridge cranes 4 approach each other. When they reach a suitable distance, the first movable end 111 contacts the sensor 3 on the second mating surface 161, and the second movable end 121 contacts the sensor 3 on the first mating surface 151. The sensor 3 sends a contact signal to the control mechanism. Upon receiving the signal from the sensor 3, the control mechanism controls the bridge crane 4 to stop running and transmits a signal to the fixing mechanism 2 for fixing operation. Once the fixing mechanism 2 is connected, it sends a completion signal to the bridge crane 4 operating system, and the bridge crane 4 performs parallel lifting work.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
