[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] When the high-voltage switch operating mechanism is being assembled and finished, it is necessary to flip the mechanism 180 degrees and stick the sealing strip. The operation of this process is still mainly done manually. During the operation, the operating mechanism is hoisted by using lifting equipment, and then manually flipped. Due to the heavy weight of the operating mechanism itself, manual flipping is very inconvenient. The flipping operation of a single mechanism takes about ten minutes. At the same time, due to the manual operation, there are technical problems such as high risk and low efficiency.

[0032] In order to solve the above technical defects, the inventor provides an automated high-voltage switch operating mechanism clamping and flipping device and method.

[0033] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figure 1-Figure 3As shown, in the embodiment of the present invention, the first aspect provides an automated high-voltage switch operating mechanism clamping and flipping mechanism, comprising: a load device, on which a conveying device is provided; a lifting device, one end of which is connected to the load device and the other end of which is connected to a flipping device; a flexible clamping device, which is connected to the flipping device, and a buffer device is provided on the flexible clamping device; a control device, which is electrically connected to the conveying device, the lifting device, the flipping device and the flexible clamping device; wherein the conveying device is used to convey the operating mechanism to be flipped to the load device, and the flipping device, the flexible clamping device and the buffer device cooperate to clamp and flip the operating mechanism to be flipped. The mechanism realizes the full-process automated operation from conveying, clamping to flipping of the operating mechanism to be flipped by integrating the conveying device, the lifting device, the flipping device and the flexible clamping device, which greatly reduces manual intervention, improves production efficiency, and reduces the risk of errors or safety accidents caused by improper human operation. At the same time, the design of the flexible clamping device, in conjunction with the buffer device, can provide appropriate pressure and buffer when clamping the operating mechanism, avoids damage to the mechanism, ensures stability during the flipping process, and reduces positioning deviations caused by vibration or impact. In addition, automated operation reduces the impact of human factors on product quality, such as uneven operating force and inaccurate positioning. In addition, by precisely controlling the flip angle and speed, the mechanism can ensure that the operating mechanism remains in the best condition during the flipping process, thereby improving the overall quality and reliability of the product. Due to the improvement in production efficiency and product quality, the production cost and maintenance cost are also reduced accordingly. The mechanism has a certain degree of versatility and can adapt to operating mechanisms of different models or sizes by adjusting the control program or replacing some components. This flexibility and adaptability enable the mechanism to be widely used in the production and maintenance of various high-voltage switches. Figure 1As shown, the conveying device includes a tray 3 and a rotary disc 2 mounted on the tray 3, and the tray 3 is mounted on the top of the load device; the flexible clamping device includes a clamping block 4, a fixed seat 5, a fixed seat mounting plate 6, a first side plate 7, a cylinder mounting plate 13, a mounting bent plate 14, a tail flange 15, a second side plate 16, a first sliding bearing base 17, a rod end flange 28, a clamping cylinder 27, a piston rod 31 and a guide shaft 32, and the first side plate 7 and the second side plate 16 are both mounted with a fixed seat mounting plate 6, and the fixed seat mounting plate 6 is mounted with a fixed seat 5 and a clamping block 4, and three groups of clamping blocks 4 are provided. In the above structure, the combination design of the tray 3 and the rotary disc 2 enables the operating mechanism to be turned over to be stably placed on the tray 3, and to achieve accurate positioning and transportation through the rotary disc 2, ensuring that the operating mechanism will not deviate or slip during the transportation process, improving the accuracy and stability of transportation, and being able to continuously and efficiently transport the operating mechanism to be turned over, reducing manual handling and waiting time, thereby improving overall production efficiency. Through the cooperation of the clamping module composed of three groups of clamping blocks 4 and fixed seat 5, fixed seat mounting plate 6, first side plate 7, second side plate 16, cylinder mounting plate 13, rod end flange 28, clamping cylinder 27, fixed seat 5, fixed seat mounting plate 6, clamping block 4 and piston rod 31, the stable clamping of the flip operating mechanism is achieved. This multi-point clamping method can evenly distribute the clamping force and avoid local damage to the operating mechanism. In addition, the cylinder mounting plate 13 and the mounting bent plate 14 enable the clamping device to flexibly adjust the clamping position and angle according to actual needs, thereby improving the flexibility and accuracy of the operation. The clamping cylinder 27 drives the clamping block 4 to perform the clamping operation through the piston rod 31, thereby realizing automatic control, reducing manual intervention, and improving the accuracy and efficiency of the operation. The cooperation of the guide shaft 32 and the rod end flange 28 not only provides a stable guide for the clamping operation, but also plays a buffering and protective role to a certain extent, reducing the impact and vibration during the clamping process.

[0034] In this embodiment, the first side plate 7 is fixedly connected to the clamping cylinder 27 by installing the bent plate 14 and the tail flange 15, providing a stable support point for the clamping cylinder 27, ensuring the stability of the clamping cylinder 27 during operation, and effectively preventing the clamping cylinder 27 from being offset due to uneven force or vibration, thereby improving the accuracy and reliability of the clamping operation. The bent plate 14 and the tail flange 15 are installed as connectors, making the connection between the clamping cylinder 27 and the first side plate 7 more flexible and adjustable. During the installation or commissioning of the equipment, the working position and clamping force of the clamping cylinder 27 can be optimized by adjusting the position and angle of these connectors, thereby meeting the clamping requirements of operating mechanisms of different models or sizes. Since the clamping cylinder 27 is connected to the first side plate 7 by installing the bent plate 14 and the tail flange 15, when the clamping cylinder 27 needs to be repaired or replaced, it can be disassembled and reinstalled more conveniently, reducing the difficulty and cost of maintenance.

[0035] In this embodiment, the clamping cylinder 27 is equipped with a piston rod 31, and the other end of the piston rod 31 is fixed to the second side plate 16. The piston rod 31 directly connects the clamping cylinder 27 and the second side plate 16, realizing direct force transmission, reducing intermediate transmission links, making the clamping action more rapid and sensitive, and helping to shorten the clamping time and improve production efficiency. The direct connection between the piston rod 31 and the second side plate 16 makes the structure of the clamping device more compact, reducing unnecessary space occupation, and the fixed connection between the piston rod 31 and the second side plate 16 is usually a simple threaded connection or a pin connection, which is easy to disassemble and replace. When the clamping device needs to be repaired or overhauled, the piston rod 31 and the second side plate 16 can be quickly disassembled, reducing the difficulty and cost of maintenance.

[0036] The guide shaft 32 is arranged on the flipping device, and a limit nut 33 is arranged on one side of the guide shaft 32, and a first limit pin 34 is installed on the limit nut 33, and a polyurethane pad 35 is installed on one side of the first limit pin 34. A first sliding bearing base 17 is sleeved on the guide shaft 32, and two first sliding bearing bases 17 are provided, one of which is connected to the first side plate 7, and the other is connected to the second side plate 16. The guide shaft 32 provides a stable guide for the flipping device, ensuring the stability and accuracy during the flipping process. Through the cooperation of the two first sliding bearing bases 17 and the guide shaft 32, the lateral deviation of the flipping device during the flipping process is limited, making the flipping action more stable and reliable. The first sliding bearing base 17, as the supporting point of the guide shaft 32, has a strong bearing capacity. The two first sliding bearing bases 17 are respectively connected to the first side plate 7 and the second side plate 16, which disperses the load generated during the flipping process and improves the bearing capacity of the entire flipping device.

[0037] A sliding bearing or lubrication device is usually provided inside the first sliding bearing base 17, which can reduce the friction and wear between the guide shaft 32 and the first sliding bearing base 17, extend the service life of the guide shaft 32 and the first sliding bearing base 17, and reduce the maintenance cost of the equipment; and, through the cooperation of the guide shaft 32 and the first sliding bearing base 17, the flipping angle and speed of the flipping device can be accurately controlled, thereby improving the accuracy and controllability of the flipping, and helping to meet different production needs. Finally, the connection between the guide shaft 32 and the two first sliding bearing bases 17 forms a stable triangular structure, which enhances the structural rigidity of the flipping device, making it less likely for the flipping device to be deformed or damaged when subjected to a large load, thereby improving the stability and durability of the equipment. Figure 1As shown, the flipping device includes a speed reducer 24, a first shaft 37, a first operating arm 18, a second operating arm 36 and a rolling bearing 39, a mounting plate 40 is installed on one side of the rolling bearing 39, and a micro switch 41 is installed on one side of the mounting plate 40; a lifting device is provided on the speed reducer 24, and the driving end of the speed reducer 24 is connected to the first shaft 37, and the first operating arm 18 and the second operating arm 36 are installed on the first shaft 37. As a power source, the speed reducer 24 can provide a stable and adjustable driving force. Through the speed reducer 24, the flipping speed and flipping torque can be accurately controlled to meet the needs under different working conditions. As the main transmission component of the flipping device, the first shaft 37 connects the speed reducer 24 and the first operating arm 18 and the second operating arm 36 to realize the transmission of power. The first operating arm 18 and the second operating arm 36 are installed on the first shaft 37 and can flip with the rotation of the first shaft 37, thereby realizing accurate control of the flipped object and reducing friction and wear. The introduction of the rolling bearing 39 effectively reduces the friction and wear during the flipping process. The rolling bearing 39 can withstand large radial and axial loads while maintaining a low friction coefficient, thereby extending the service life of the flipping device. The first spring 25 is installed on the second stop pin 26, and the rod end flange 28 is installed on the clamping cylinder 27. The rolling bearing 39 also has good self-rotation performance, which helps to reduce energy loss during the flipping process and improve flipping efficiency. Through the coordinated action of the reducer 24, the first shaft 37, the first operating arm 18 and the second operating arm 36, the flipping device can efficiently complete the flipping operation of the object, thereby improving work efficiency. At the same time, since the motion trajectory and force conditions of each component during the flipping process are accurately controlled, the safety of the operation is also improved, and the possibility of accidents is reduced.

[0038] In this embodiment, the lifting device includes a bearing seat 38, a square tube 42, a third sliding bearing base 43, a second shaft 44, a lifting piston rod 46 and a lifting cylinder 47. The lifting piston rod 46 is arranged in the lifting cylinder 47, and the end of the lifting piston rod 46 is connected to the square tube 42. The bearing seat 38 and the second shaft 44 are installed on the square tube 42, and the second shaft 44 passes through the third sliding bearing base 43. The lifting cylinder 47, as a power source, transmits the lifting force through the lifting piston rod 46, which can provide a continuous and controllable lifting force to ensure the smooth progress of the lifting process. The direct connection between the lifting piston rod 46 and the square tube 42 reduces the loss in the force transmission process and improves the lifting efficiency. The square tube 42, as the main supporting structure of the lifting device, has sufficient strength and rigidity and can withstand various forces and moments in the lifting process. The installation of the bearing seat 38 and the second shaft 44 provides stable support and guidance for the square tube 42, ensuring stability and accuracy during the lifting process. The second shaft 44 passes through the third sliding bearing base 43, reducing friction and wear and improving the durability of the lifting device.

[0039] In this embodiment, the buffer device includes a support plate protective pad 8, a support plate 9, a sliding arm 10, a first guide pin 11, a base 12, a second sliding bearing base 19, a buffer spring 20, a second guide pin 21, a washer 22, a nut 23, a second spring 29, and a stop sleeve 30; the second sliding bearing base 19 is fixed on the fixed seat mounting plate 6 of the clamping device, the second sliding bearing base 19 is covered with the buffer spring 20, and the second sliding bearing base 19 is penetrated with the second guide pin 21. The buffer spring 20 is sleeved outside the second sliding bearing base 19. When subjected to external impact or vibration, the buffer spring 20 can absorb and disperse these energies, thereby playing an effective buffering role, helping to protect the clamping device and the mechanism to be flipped clamped therein from damage and prolonging the service life of the device. The second guide pin 21 passes through the second sliding bearing base 19, providing a stable guide for the sliding arm 10, ensuring the stability and accuracy of the sliding arm 10 during movement, and preventing errors caused by offset or shaking. At the same time, the second sliding bearing base 19 serves as a supporting point, providing a solid support for the entire buffer device and enhancing the rigidity and stability of the device; the coordinated use of the nut 23 and the washer 22 allows the preload force of the buffer spring 20 to be easily adjusted, and the buffering effect of the buffer device can be adjusted according to actual needs, thereby improving the flexibility and adaptability of the device.

[0040] A washer 22 and a nut 23 are mounted on one end of the second guide pin 21. The washer 22 and the nut 23 are used to limit the position of the buffer spring 20. The combination of the washer 22 and the nut 23 can accurately control the compression and extension of the buffer spring 20. By adjusting the tightening degree of the nut 23, the preload of the buffer spring 20 can be changed, thereby achieving accurate adjustment of the buffer effect, which helps to ensure that the buffer device can perform buffering in a predetermined manner when subjected to impact or vibration, thereby improving the stability and reliability of the device. The combination of the washer 22 and the nut 23 effectively prevents the buffer spring 20 from falling off or deviating from the second guide pin 21 during vibration or impact, thereby ensuring that the buffer spring 20 always remains in the correct position, thereby ensuring the normal operation of the buffer device. The nut 23 is fastened to the second guide pin 21, and together with the washer 22, forms a stable connection structure, which enhances the rigidity and stability of the buffer device, enabling it to better withstand external impact and vibration. At the same time, it also helps to reduce the noise and wear caused by vibration or impact, thereby extending the service life of the device. The design of the washer 22 and the nut 23 makes it easier to install and replace the buffer spring 20. During installation, the buffer spring 20 only needs to be sleeved on the second guide pin 21 and then fixed with the washer 22 and the nut 23. During maintenance, if the buffer spring 20 needs to be replaced or adjusted, it can also be easily achieved by removing the nut 23 and the washer 22.

[0041] In this embodiment, the other end of the second guide pin 21 is fixed to the sliding arm 10, and the first guide pin 11 is also fixed to the sliding arm 10. The other end of the first guide pin 11 is provided with a second spring 29 and a stop sleeve 30; the first guide pin 11 and the base 12 form a sliding pair, and the base 12 is provided with a support plate 9, and the support plate protection pad 8 is provided on the support plate 9. The sliding pair formed by the first guide pin 11 and the base 12 provides a stable guide and sliding path for the sliding arm 10, ensuring that the sliding arm 10 can slide smoothly along a predetermined trajectory without deviation or shaking when subjected to external forces. The second spring 29 and the stop sleeve 30 provide a buffer and limit function for the sliding arm 10. When the sliding arm 10 is impacted or vibrated, the second spring 29 can absorb and disperse the energy, thereby reducing the impact on other parts of the device. At the same time, the stop sleeve 30 limits the movement range of the sliding arm 10 to prevent it from excessive movement causing damage or safety accidents. The provision of the support plate 9 and the support plate protection pad 8 provides additional support and protection for the clamping device or the workpiece. The support plate 9 can bear part of the weight and force, while the support plate protection pad 8 can prevent direct contact with the support plate 9, thereby avoiding scratches or damage.

[0042] In this embodiment, the load device includes a load support frame 1 and a gantry 45 . The gantry 45 is disposed on the top of the load support frame 1 , and the tray 3 is disposed on the top of the gantry 45 .

[0043] In a second aspect, a method for clamping and flipping an automated high-voltage switch operating mechanism is provided, wherein the method is performed using the clamping and flipping mechanism as described above. Figure 4 As shown, including: S101, place the operating mechanism to be flipped on the conveying device so that the operating mechanism to be flipped is moved to the load device; illustratively, the clamping and flipping mechanism is controlled by a PLC controller as a whole, wherein there are magnetic rings in the clamping cylinder 27 and the lifting cylinder 47. When the clamping cylinder 27 contracts or extends, the magnetic rings feedback signals to the PLC controller, and the PLC controller sends a signal for the next action after timing for several seconds. At the same time, the mounting plate 40 and the micro switch 41 provided in the device are used to cut off the power supply of the reducer 24 circuit and the control circuit signal when the flipping mechanism to be flipped is flipped into place. The specific action principle is as follows: before the clamping and flipping mechanism is operated, it is in the initial position, and the square tube 42 and the first operating arm 18 and the second operating arm 37 installed thereon are in the lifting state; when the clamping operation is required, the operating mechanism to be flipped is placed on the rotary disc 2 of the conveying device, and together with the conveying device as a whole, it is transported to the load support frame 1 of the load device through the conveyor belt; at this time, the remote control button is pressed to issue a mechanism clamping and flipping instruction.

[0044] S102, using the control device to make the turning device, the flexible clamping device and the buffer device cooperate to turn the operating mechanism to be turned over 180 degrees. For example, after the PLC controller receives the command, the circuit of the reduction motor 24 is connected, the reducer 24 rotates, and drives the turning device, the clamping device, the buffer device and the clamped operating mechanism to rotate 180 degrees around the first axis 37 to the top of the load support frame 1. At this time, the micro switch 41 is switched, the circuit of the reduction motor 41 is powered off, and the PLC controller issues a descending command.

[0045] After the PLC controller receives the command, the solenoid valve acts to control the lifting cylinder 47 and the lifting piston rod 46 of the lifting device to contract, driving all other devices except the load device and the conveying device to descend. When descending to the preset position, the magnetic ring in the lifting cylinder 47 sends a signal of descending to the PLC controller, and after several seconds, the PLC controller issues a clamping command; after the clamping and flipping mechanism receives the clamping command, the solenoid valve controls the clamping cylinder 27 and the piston rod 31 to contract. When contracted to the preset position (the clamping action has been completed at this time), the magnetic ring in the clamping cylinder 27 sends a signal of clamping to the PLC controller, and after several seconds, the PLC controller issues a flipping command; after receiving the clamping command, the circuit of the reduction motor 24 is connected, and the reducer 24 rotates, driving the flipping device, the clamping device, the buffer device and the operating mechanism to be flipped to rotate around the first axis 37. When the flip is completed by 180 degrees, the second operating arm 36 presses the micro switch 41 to switch it, and the power supply of the circuit of the reduction motor 24 is disconnected, and a release command is issued to the PLC controller. After several seconds, after the PLC controller receives the command, the solenoid valve controls the clamping device's clamping cylinder 27 and piston rod 31 to relax and disconnect the control signal; at this time, the buffer device buffers and supports the clamping flip mechanism, and the flip device returns to its initial position. At this point, the flip operation is completed, and the sealing strip can be manually pasted. After the pasting is completed, the operating mechanism can be manually transferred to the storage area, and the device can be controlled again to finish pasting the sealing strip on the next machine.
