Description

Technical Field

[0001] The invention relates to an intelligent transport trolley for high-voltage vacuum circuit breakers and relates to the technical field of transport equipment. Background Art

[0002] The rated current of the 10KV vacuum circuit breaker in the high-voltage switch cabinet ranges from 630A to 3150A, and the heaviest one weighs nearly 300 kilograms. It is difficult and unsafe to move it manually, so transfer carts are installed in the distribution room.

[0003] Conventional transfer carts are used in existing power distribution rooms. They adopt a mechanical structure with fixed height and fixed width. The equipment is relatively simple, easy to process and low in cost. However, when transferring the circuit breaker in the switch cabinet, the transfer cart and the switch cabinet need to be aligned in height and level. Conventional transfer carts can only be adjusted by manually rotating the screw. Due to the heavy weight of the circuit breaker, the alignment adjustment is difficult and the work efficiency is low. Moreover, a transfer cart is only suitable for transferring circuit breakers of the same height and breaking degree (the various cabinet-type circuit breakers in the power distribution room have different high voltages and widths). It has great limitations. A substation often needs to be equipped with multiple transfer carts, which occupy a large space. It is necessary to select circuit breakers of matching height according to the installation height of the circuit breaker. Moreover, during the transportation of circuit breakers at a higher position, due to the high center of gravity, there is a risk of overturning, falling, etc., which endangers the personal and equipment safety of the operation and maintenance personnel. In addition, the bottom of the circuit breaker support of the existing transfer cart is closed. When the bottom position of the circuit breaker needs to be repaired, it needs to be transported to other positions again, which increases the workload and transportation risks.

DETAILED DESCRIPTION

[0026] See also Figure 1-Figure 8 As shown, the technical solution adopted in this specific embodiment is: it includes a transfer trolley body 1, and the transfer trolley body 1 includes an active lifting column 11 and a driven lifting column 12, the active lifting column 11 and the driven lifting column 12 are connected by a synchronous belt transmission, and a supporting arm 4 is arranged on them. In this embodiment, there is a connecting cavity between the two lifting columns, and a synchronous belt is arranged in the cavity to connect them, so that the active lifting column can drive the driven lifting column to synchronously drive the two supporting arms to lift;

[0027] A translation mechanism 3 is provided on the support arm 4, and an adjustable tray mechanism 2 is provided on the translation mechanism 3. The translation mechanism can drive the adjustable tray mechanism to translate on it, so that after the height adjustment is completed, it can be further adjusted with the circuit breaker to ensure that the circuit breaker can be accurately moved to the adjustable tray mechanism;

[0028] More specifically, the translation mechanism 3 includes a bottom plate 31, which is a frame structure. A translation guide rail 33 is arranged in the middle of the bottom plate 31, and a translation bracket 32 ​​is slidably arranged on the translation guide rail 33. In this embodiment, the bottom plate is a frame structure with a large area of ​​empty slots. When the circuit breaker is transferred to the adjustable tray mechanism, the circuit breaker can be directly repaired from the bottom without having to transfer it to the maintenance station, which can greatly improve work efficiency and solve the problem of difficult maintenance.

[0029] A limiting wheel 34 is provided on the translation bracket 32, and a mounting groove 25 is provided at the bottom center of the adjustable tray mechanism 2, and the mounting groove 25 is matched and connected with the limiting wheel 34. The adjustable tray mechanism is connected with the limiting wheel through the mounting groove, and a notch can be provided on the mounting groove to match the limiting wheel, which can make connection and positioning more convenient. At the same time, after the limiting wheel is connected to the mounting groove, it can also drive the entire adjustable tray mechanism to translate;

[0030] The front end of the support arm 4 is provided with a laser radar 5, model T50 three-dimensional depth imaging laser radar;

[0031] In this embodiment, when transporting a circuit breaker, first move the transport trolley body to the relative position of the circuit breaker to be transported, press the switch to power on the equipment, the equipment performs self-test, and all mechanisms are reset. At this time, select the corresponding size on the control panel according to the required width of the transported circuit breaker, and the adjustable tray automatically adjusts to the corresponding width. Then, by selecting the height control, the active lifting column drives the driven lifting column to move up and down, thereby driving the translation mechanism to move up and down to the position of the circuit breaker. After the translation mechanism moves to the height of the circuit breaker, the laser radar is automatically turned on for alignment. The laser radars on both sides perform three-dimensional imaging alignment of the circuit breaker and transmit the alignment data back to the control main board. When the laser radar is in the same position as the edge of the circuit breaker during the scanning process, the laser radar will automatically start to align with the position of the circuit breaker. If the edge of the laser radar is aligned with the edge of the circuit breaker, the circuit breaker can be pulled out for transportation after the alignment is completed. If the laser radar position is not aligned with the edge of the circuit breaker, the control main board sends a control message to drive the translation mechanism to move slowly horizontally. The laser radar continues to scan and detect until the alignment is accurate, and the control main board sends a stop signal to the translation mechanism. At this time, the adjustable tray is aligned with the circuit breaker, and the circuit breaker can be pulled out for transportation. During the entire operation, the operator only needs to move the transfer trolley body to the position of the circuit breaker to be transported, and set the corresponding height and width. The equipment will automatically lift and adjust the position. After the adjustment, the circuit breaker can be directly pulled out. The overall degree of automation is high, the work intensity of the operators is low, and the safety is higher.

[0032] More specifically, a first T-shaped lead screw 111 is arranged in the active lifting column 11, a first lifting guide rail 114 is arranged on one side of the first T-shaped lead screw 111, a servo motor 113 is arranged at the bottom of the first T-shaped lead screw 111, and the bottom of the first T-shaped lead screw 111 is connected to the output shaft of the servo motor 113, a transmission wheel 112 is also arranged on the first T-shaped lead screw 111, a first lifting seat 115 is arranged on the first T-shaped lead screw 111, and a guide groove is arranged on the inner side of the first lifting seat 115 to match the first lifting guide rail 114. In this embodiment, a T-shaped lead screw is used, and the T-shaped lead screw has a self-locking function. When the equipment fails, it can effectively prevent the safety accident caused by sliding down during sudden power failure. During operation, the servo motor drives the first T-shaped lead screw to rotate and drives the first lifting seat to lift and lower along the first lifting guide rail.

[0033] More specifically, the driven lifting column 12 is provided with a second T-shaped screw rod 121, a second lifting guide rail 124 is provided on one side of the second T-shaped screw rod 121, a second lifting seat 126 is provided on the second T-shaped screw rod 121, and a guide groove is also provided on the inner side of the second lifting seat 126 to match the second lifting guide rail 124, a driven wheel 123 is provided on the second T-shaped screw rod 121, and the driven wheel 123 is connected to the transmission wheel 112 through a synchronous belt transmission, and a driving electromagnetic clutch 122 is provided at the bottom of the second T-shaped screw rod 121. In this embodiment, the driven lifting column is synchronously driven by the active lifting column, specifically The driven wheel and the transmission wheel are connected through a synchronous belt drive. The transmission wheel can synchronously drive the driven wheel to drive the second T-type lead screw to rotate, thereby synchronously driving the second lifting seat to lift and lower. When horizontal adjustment is required, the driving electromagnetic clutch model is DDL3-20. The rotation of the second T-type lead screw is controlled by controlling the on and off of the driving electromagnetic clutch. When power is on, power is transmitted. When power is off, the coil magnetic field disappears, the separation disk relaxes, the driven device is separated from the transmission device, and the power transmission is interrupted. By continuously controlling the opening and closing of the battery, the continuous opening and closing of the clutch can be achieved, so that unilateral lifting adjustment can be performed, thereby achieving precise horizontal adjustment.

[0034] More specifically, the active lifting column 11 and the driven lifting column 12 are respectively provided with a first controller 116 and a second controller 125 at the top, and a control mainboard is provided in the first controller 116. The first controller 116 is also provided with a three-color prompt light, a voice control module and a voice speaker. The control mainboard is the main control, and automatic control is performed through a PLC control system. The height and width parameters are preset in the PLC control system, and one-button operation can be achieved. In this embodiment, the first controller is electrically connected to the second controller. The first controller controls the power-on state of the entire device and is electrically connected to the laser radar. The second controller is electrically connected to the servo motor and the driving electromagnetic clutch, and is mainly used for lifting, translation and horizontal state adjustment control. After receiving the laser radar and the input control information, the control mainboard automatically controls each mechanism. Therefore, not only the control accuracy is high, but also the workload of operators is reduced, and the operation safety is improved. When the equipment is running, the three-color prompt light cooperates with the voice control module to give prompts corresponding to the operating status. At the same time, the voice control module controls the voice speaker to give voice warnings to the corresponding prompt light. Specifically, when the equipment is powered on for self-test, the PLC control system sends a corresponding signal, the prompt light is displayed in yellow, and the voice control module sends a corresponding signal, and the speaker broadcasts "power supply self-test". After the self-test is completed without any faults, the speaker broadcasts "equipment is normal" and the prompt light is displayed in blue, indicating that there is no fault in power supply and the equipment is normal. When the equipment fails, such as the failure of each detection device to complete the adjustment and feedback to the control main board, the PLC control system sends the corresponding detection device's broadcast information to the voice control module, and then sends a corresponding voice broadcast "equipment failure" through the speaker.

[0035] More specifically, the adjustable tray mechanism 2 includes a tray bracket 21 and a circuit breaker base plate 22. Four base plate guide rails 23 are arranged on the tray bracket 21. Two circuit breaker base plates 22 are movably arranged on the base plate guide rails 23. A transverse driving mechanism 24 is arranged at the bottom of the circuit breaker base plate 22. The two movably arranged circuit breaker base plates are slidably connected with the base plate guide rails through the bracket and the guide grooves thereon, so that the two circuit breaker base plates can move laterally on the tray bracket, thereby realizing width adjustment, and can be adapted to circuit breakers of different specifications, so that one tray can be used in the entire distribution room without the need to configure multiple transfer carts.

[0036] More specifically, pallet lock sensors 26 are provided on both sides of the installation slot 25, and lock holes 251 are provided at positions of the installation slot 25 corresponding to the pallet lock sensors 26. A pallet drive servo motor 35 is also provided at the bottom of the base plate 31. The pallet drive servo motor is electrically connected to the second controller and to the laser radar. The output end of the pallet drive servo motor 35 is connected to the bottom of the translation bracket 32. A locking mechanism 36 is provided on one side of the translation bracket 32 ​​to cooperate with the lock hole 251 on the installation slot 25. In this embodiment, the pallet lock sensor is provided on the same side as the locking mechanism and is away from the transfer side of the circuit breaker. When the installation slot contacts the locking mechanism and is plugged into place, the locking mechanism is rotated so that the locking piece on the locking mechanism is turned into the lock hole to lock the installation slot. At this time, the pallet lock sensors on both sides detect that the locking mechanism has been locked in place and send a signal of being in place. Only then can the lifting operation be performed, thereby ensuring the safety of the operation.

[0037] In addition, in this embodiment, the adjustable tray also needs to perform a small range of translation adjustment to ensure that it can correspond to the position of the circuit breaker. A small range of movement is achieved by setting a tray drive servo motor to drive the translation bracket to move on the translation guide rail, and the translation alignment is automatically adjusted through laser radar signal judgment, with a high degree of automation and more convenient operation.

[0038] To be more specific, a tray support adjustment roller 41 is provided at the upper front end of the support arm 4, and the tray support adjustment roller 41 is rollingly connected to the tray bracket 21. The tray support adjustment roller can make the adjustable tray mechanism move more smoothly, thereby improving the stability and safety of the equipment operation.

[0039] The working principle of the present invention is as follows: when performing the circuit breaker transfer operation, first press the start switch on the first controller 116 to perform a power-on self-test of the equipment, confirm that the installation slot 25 has been inserted into the end of the translation bracket 32, and lock the adjustable tray mechanism 2 and the translation mechanism 3 through the locking mechanism 36. The tray lock sensor 26 detects that the locking mechanism 36 has been locked in place and sends a position signal. At this time, the transfer operation can be started, and the trolley is moved to the required transfer circuit breaker position through the handle on the transfer trolley body 1. According to the width of the circuit breaker, the corresponding operation item is selected on the first controller 116, and the fork position button is pressed. The control signal is output through the direction operation key of the second controller 125. The horizontal drive mechanism 24 receives the signal to control the rotation of the transmission rod on it and drive the two circuit breaker bottom plates 22 to move horizontally to adjust the spacing, and select the lifting height according to the position of the circuit breaker. The servo motor 113 starts to work, drives the first T-type screw rod 111 to rotate, and the transmission wheel 112 rotates synchronously with the first T-type screw rod 111, and drives the driven wheel 123 to rotate synchronously under the synchronous belt drive, so that The second T-type screw rod 121 is driven to rotate. While the two screw rods are rotating, the first lifting seat 115 and the second lifting seat 126 rise along the first lifting guide rail 114 and the second lifting guide rail 124, thereby driving the two supporting arms 4 to rise, and driving the adjustable tray mechanism 2 and the translation mechanism 3 to rise to the required transportation position of the circuit breaker. At this time, if the adjustable tray mechanism 2 is not in a completely horizontal position, the electromagnetic clutch 122 can be controlled by the second controller 125 to be turned on and off, so as to drive the second T-type screw rod 121 alone, so as to adjust the lifting of the second lifting seat 126 to achieve the adjustment of the horizontal position. After the adjustment is completed, the laser radar 5 is automatically started for alignment, and the tray drive servo motor 35 is controlled to work, through which the translation bracket 32 ​​is driven to translate on the translation guide rail 33, and it is completely corresponding to the position of the circuit breaker. After all adjustment operations are completed, the circuit breaker can be pulled out to the adjustable tray mechanism 2 for transportation. The entire adjustment process can be completed by operating the control panel, with a high degree of automation, which greatly reduces the work intensity of the operators and improves the work efficiency.
