Description

Technical Field

[0001] This invention relates to the field of power tools, and in particular to a convenient 10kV switch transfer trolley. Background Technology

[0002] A 10kV switch transfer trolley is a tooling trolley used to pull out or push circuit breakers from switchgear into the circuit breaker compartment. Existing technologies, such as invention patent CN116845756A and utility model patent CN208028464U, disclose liftable transfer trolleys. These require placing the circuit breaker on the trolley's frame, manually pushing it into the circuit breaker compartment, and locking the circuit breaker's locking clip to the switchgear. To pull out the circuit breaker, the transfer trolley is docked with the switchgear, the locking clip is unlocked, and the circuit breaker is manually pulled out. The circuit breaker itself is heavy, and the transfer trolley occupies the opening of the switchgear. Operators need to lean to pull it out or push it into the circuit breaker compartment, which is quite strenuous. Furthermore, since the switchgear is a high-voltage power distribution device, operators may face the risk of electric shock. Summary of the Invention

[0003] The purpose of this invention is to provide a convenient 10kV switch transfer trolley, which solves the problems of laborious and unsafe movement of circuit breakers in the prior art, making the movement of circuit breakers more labor-saving, simple and safe.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a convenient 10kV switch transfer trolley, comprising a frame and a control center. The frame is equipped with a transfer platform for carrying circuit breakers inside the switch cabinet. The frame is equipped with a lifting and adjusting mechanism for adjusting the height of the transfer platform. The transfer platform is equipped with an operating gripper, a horizontal driver, a vertical driver, a vertical slide rail, and a horizontal slide rail slidably connected to the vertical slide rail. The operating gripper is connected to the horizontal slide rail. The circuit breaker is equipped with a locking buckle that can move laterally and lock or unlock with the switch cabinet, and an operating handle that moves synchronously with the locking buckle. The operating gripper and the operating handle are manually connected. The control center controls the vertical driver to drive the horizontal slide rail to slide longitudinally on the vertical slide rail to push the circuit breaker into or out of the switch cabinet. The control center controls the horizontal driver to drive the operating gripper to slide laterally to lock or unlock the locking buckle with the switch cabinet.

[0005] After adopting the above technical solution, the present invention has the following advantages: the operator only needs to manually connect the operating gripper and the operating handle. Subsequent operations are controlled by the control center to control the actions of the longitudinal and transverse drives, realizing the automatic pushing in, moving out, locking or unlocking of the circuit breaker, which greatly reduces manual intervention. The operator can perform the connection operation from a more natural position without having to tilt their body or enter narrow spaces, making the movement of the circuit breaker more effortless and convenient, improving work efficiency, and minimizing direct contact between the operator and high-voltage equipment, reducing the risk of electric shock and enhancing safety. Furthermore, the longitudinal and transverse slide rails provide a more stable moving path for the operating gripper, ensuring that it can reach the predetermined position with high precision. This not only helps to improve the docking accuracy between the circuit breaker and the switchgear, but also ensures that the locking buckle and the switchgear locking or unlocking process proceed smoothly.

[0006] Furthermore, the frame is also equipped with a position sensor that identifies the position of the locking buckle and converts it into an electrical signal to be sent to the control center. The control center controls the start of the longitudinal drive after the position sensor identifies that the locking buckle is in the unlocked position.

[0007] By adopting the above technical solution, the position sensor automatically detects whether the locking buckle is in the unlocked position and feeds the information back to the control center. Only when the control system confirms that the circuit breaker has been fully unlocked will the longitudinal drive be activated to push in or remove the buckle. This effectively prevents equipment damage caused by improper unlocking.

[0008] Furthermore, the transverse slide rail includes a base, a screw rod disposed on the base, and a first slider. The first slider is threadedly connected to the screw rod via a nut. The operating gripper is disposed on the first slider. The output end of the transverse driver is fixedly connected to the screw rod.

[0009] By adopting the above technical solution, the screw drive system usually has a certain self-locking characteristic. When the driver stops working, the friction between the screw and the nut can prevent the slider from sliding on its own.

[0010] Furthermore, the base is provided with guide rails arranged along the axial direction of the screw, and the first slider is provided with a connecting groove that mates with the guide rails.

[0011] By adopting the above technical solution, the cooperation between the guide rail and the connecting groove ensures that the first slider can only move along the predetermined path, reducing lateral offset or wobbling, thereby maximizing the straightness and positional accuracy of the operating gripper movement.

[0012] Furthermore, the longitudinal slide rail includes a rack and pinion slide and a second slider, the second slider being connected to the rack and pinion slide via a gear, and the output end of the longitudinal driver being fixedly connected to the gear.

[0013] Furthermore, the longitudinal drive is vertically positioned perpendicular to the transfer platform.

[0014] By adopting the above technical solution, the longitudinal drive is set vertically to the transfer platform, which can effectively save horizontal space, making the whole equipment more compact and reducing interference with other equipment.

[0015] Furthermore, there are two operating grippers, two transverse slide rails, and two transverse drivers. The two transverse slide rails are arranged laterally on both sides of the longitudinal slide rail and are simultaneously slidably connected to the longitudinal slide rail. The two transverse drivers simultaneously drive the two operating grippers to move laterally towards or away from each other.

[0016] Using the above technical solution, the two operating grippers can be precisely and synchronously controlled to ensure that they move towards or away from each other at the same time, thereby achieving smooth gripping and release of the circuit breaker's operating handle.

[0017] Furthermore, the operating gripper includes a connecting seat, an operating handle, and a gripper portion. One end of the operating handle is rotatably connected to the connecting seat, and the other end of the operating handle is fixedly connected to the gripper portion. The connecting seat is provided with a locking element for locking the operating handle.

[0018] By adopting the above technical solution, the locking component can be firmly locked after the operating handle is adjusted to the appropriate position, ensuring that the operating gripper remains stable throughout the operation and does not change its angle due to external force or vibration, thereby improving the reliability and safety of gripping.

[0019] Furthermore, the vehicle frame is also equipped with a lateral adjustment mechanism for adjusting the horizontal position of the transfer platform.

[0020] By adopting the above technical solution, different switchgear and circuit breakers may have different installation position requirements. The lateral adjustment mechanism allows the transfer platform to be adjusted according to specific circumstances, which enhances the versatility and adaptability of the equipment.

[0021] Furthermore, the transfer platform is equipped with cable routing racks for the horizontal and vertical drives.

[0022] By adopting the above technical solution, the cable tray can help to arrange cables in an organized manner, making the space on the transfer platform more tidy and orderly. Attached Figure Description

[0033] The technical solution of the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0034] like Figures 1 to 3 As shown, the present invention provides a convenient 10kV switch transfer trolley, including a frame 10 and a control center 20. The frame 10 is provided with a transfer platform 30 for carrying circuit breakers 60 in the switch cabinet. The frame 10 is provided with a lifting adjustment mechanism 40 for adjusting the height of the transfer platform 30. The transfer platform 30 is provided with an operating gripper 50, a horizontal driver 51, a vertical driver 52, a vertical slide rail 53, and a horizontal slide rail 54 slidably connected to the vertical slide rail 53. The operating gripper 50 is connected to the horizontal slide rail 54. The circuit breaker 60 is provided with a locking buckle 61 that can move laterally and lock or unlock with the switch cabinet, and an operating handle 62 that moves synchronously with the locking buckle 61. The operating gripper 50 and the operating handle 62 are manually connected. The control center 20 controls the vertical driver 52 to drive the horizontal slide rail 54 to slide longitudinally on the vertical slide rail 53 to push the circuit breaker 60 into or out of the switch cabinet. The control center 20 controls the horizontal driver 51 to drive the operating gripper 50 to slide laterally to lock or unlock the locking buckle 61 with the switch cabinet.

[0035] The operator only needs to manually connect the operating gripper 50 to the operating handle 62. Subsequent operations are controlled by the control center 20, which controls the longitudinal drive 52 and the transverse drive 51. This enables the automatic pushing in, moving out, locking, and unlocking of the circuit breaker 60, greatly reducing manual intervention. The operator can perform the connection operation from a more natural position without having to tilt their body or enter narrow spaces, making the movement of the circuit breaker 60 easier and more convenient, improving work efficiency, and minimizing direct contact between personnel and high-voltage equipment, thus reducing the risk of electric shock and enhancing safety. Furthermore, the longitudinal slide rail 53 and the transverse slide rail 54 provide a relatively stable movement path for the operating gripper 50, ensuring that it can reach the predetermined position with high precision. This not only helps to improve the docking accuracy between the circuit breaker 60 and the switchgear, but also ensures that the locking buckle 61 locks or unlocks the switchgear smoothly.

[0036] Since the position of the locking buckle 61 is difficult to observe when the switchgear is locked, if the locking buckle 61 is in the locked position and the longitudinal drive 52 is directly activated, it will cause damage to the locking buckle 61. Therefore, in this invention, the frame 10 is also equipped with a position sensor that identifies the position of the locking buckle 61 and converts it into an electrical signal to be sent to the control center 20. The control center 20 controls the activation of the longitudinal drive 52 after the position sensor detects that the locking buckle 61 is in the unlocked position. By automatically detecting whether the locking buckle 61 is in the unlocked position through the position sensor and feeding the information back to the control center 20, the longitudinal drive 52 will only be activated to perform the push-in or pull-out operation when the control system confirms that the circuit breaker 60 has been fully unlocked. This effectively prevents equipment damage caused by incorrect unlocking.

[0037] It should be noted that the position sensor can be a camera that acquires the position of the locking buckle 61.

[0038] The circuit breaker 60 is equipped with two locking buckles 61, which are fixedly connected to the operating handle 62. The locking buckles 61 are also slidably connected to the circuit breaker 60. Therefore, in this invention, there are two operating grippers 50, two transverse slide rails 54, and two transverse actuators 51. The two transverse slide rails 54 are arranged laterally on both sides of the longitudinal slide rail 53 and are simultaneously slidably connected to the longitudinal slide rail 53. The two transverse actuators 51 simultaneously drive the two operating grippers 50 to move laterally towards or away from each other. The two operating grippers 50 can be precisely synchronized to ensure that they move simultaneously towards or away from each other, thereby achieving smooth gripping and release of the operating handle 62 of the circuit breaker 60.

[0039] It should be noted that the locking buckle 61 locks with the switch cabinet when moving laterally in opposite directions, and unlocks with the switch cabinet when moving laterally towards each other.

[0040] Specifically, the transverse slide rail 54 includes a base 541, a screw 542 mounted on the base 541, and a first slider 543. The first slider 543 is threadedly connected to the screw 542 via a nut. An operating gripper 50 is mounted on the first slider 543. The output end of the transverse driver 51 is fixedly connected to the screw 542. The screw 542 transmission system typically has a certain self-locking characteristic; when the driver stops working, the friction between the screw 542 and the nut can prevent the slider from sliding on its own.

[0041] To ensure more accurate positioning of the operating gripper 50, the base 541 is provided with guide rails 544 arranged along the axial direction of the screw 542, and the first slider 543 is provided with a connecting groove that mates with the guide rails 544. The cooperation between the guide rails 544 and the connecting groove ensures that the first slider 543 can only move along a predetermined path, reducing lateral offset or wobbling, thereby maximizing the straightness and positional accuracy of the operating gripper 50's movement.

[0042] Furthermore, the longitudinal slide rail 53 includes a rack and pinion slide 531 and a second slider 532. The second slider 532 is connected to the rack and pinion slide 531 via a gear, and the output end of the longitudinal driver 52 is fixedly connected to the gear. The longitudinal driver 52 is vertically arranged perpendicular to the transfer platform 30, which can effectively save horizontal space, making the entire device more compact and reducing interference with other devices.

[0043] Furthermore, the operating gripper 50 includes a connecting seat 501, an operating handle 502, and a gripper portion 503. One end of the operating handle 502 is rotatably connected to the connecting seat 501, and the other end of the operating handle 502 is fixedly connected to the gripper portion 503. The connecting seat 501 is provided with a locking member 504 for locking the operating handle 502. The locking member 504 can securely lock the operating handle 502 after it has been adjusted to a suitable position, ensuring that the operating gripper 50 remains stable throughout the entire operation process and does not change its angle due to external forces or vibrations, thereby improving the reliability and safety of gripping.

[0044] It should be noted that the locking element 504 may be a locking plate, which is rotatably connected to the connecting seat 501. The locking plate has a first position that restricts the rotation of the operating handle 502 and a second position that is away from the operating handle 502 so that the operating handle 502 can rotate.

[0045] Specifically, the operating handle 502 can rotate up and down to allow the claw 503 to hook into the operating handle 62. The connecting seat 501 is provided with a receiving groove 505 to accommodate the operating handle 502. When the operating handle 502 is horizontally positioned in the receiving groove 505, the claw 503 is lower than the operating handle 62. The operating handle 502 needs to be flipped up to hook the claw 503 into the operating handle 62. One end of the locking plate is hinged to one side of the receiving groove 505. The locking plate can rotate horizontally. When the locking plate is in the first position, both ends of the locking plate are located on both sides of the receiving groove 505. The locking plate is located above the receiving groove 505 to restrict the upward rotation of the operating handle 502. When the locking plate is in the second position, the locking plate rotates around the hinge point, and the other end of the locking plate leaves the other side of the receiving groove 505. The locking plate rotates away from the top of the receiving groove 505, allowing the operating handle 502 to rotate upward.

[0046] Different switchgear and circuit breaker 60 may have different installation position requirements. Furthermore, the frame 10 is also equipped with a lateral adjustment mechanism 70 for adjusting the horizontal position of the transfer platform 30. The lateral adjustment mechanism 70 allows the transfer platform 30 to be adjusted according to specific conditions, enhancing the equipment's versatility and adaptability. The transfer platform 30 is also equipped with a positioning lock plate and a positioning handle. The positioning lock plate is located at the front of the transfer platform 30, and the positioning handle is located at the rear of the transfer platform 30. The switchgear has a partition slot, and the lateral adjustment mechanism 70 is connected to the control center 20.

[0047] Because of the multiple drive structures, the transfer platform 30 has a large number of cables. Therefore, in this invention, the transfer platform 30 is provided with a cable tray 90 for the horizontal drive 51 and the vertical drive 52. The cable tray 90 helps to arrange the cables in an organized manner, making the space on the transfer platform 30 neater and more orderly.

[0048] When using the circuit breaker 60, before pushing the 10kV switch transfer trolley from outside the switch cabinet into the switch cabinet, carefully check whether the circuit breaker 60 is intact, whether there are any missing parts, tools or other miscellaneous items placed in the mechanism box or switch. After confirming that there are no problems, install the circuit breaker 60 on the transfer platform 30 and lock the corresponding lock. Push the 10kV switch transfer trolley to the front of the switchgear. Raise the transfer platform 30 to a suitable position using the lifting and adjusting mechanism 40. Adjust the lateral movement of the transfer platform 30 using the lateral adjusting mechanism 70 so that the positioning locking plate inserts into the middle partition slot of the switchgear, locking the 10kV switch transfer trolley to the switchgear. Manually connect the operating gripper 50 and the operating handle 62. Then, start the automatic push-in program for the circuit breaker 60. The control center 20 controls the longitudinal driver 52 to drive the lateral slide rail 54 to slide longitudinally on the longitudinal slide rail 53, pushing the circuit breaker 60 into the switchgear. The control center 20 also controls the lateral driver 51 to drive the operating gripper 50 to slide laterally, causing the locking buckle 61 to move in opposite directions and lock with the switchgear. After confirming that the circuit breaker 60 is locked to the switchgear, manually release the operating gripper 50 and the operating handle 62, run the exit program to return to the initial position. Then, manually release the lock between the transfer trolley and the switchgear, and push the 10kV switch transfer trolley away.

[0049] Circuit breaker 60 is equipped with an auxiliary circuit aviation plug. The switch cabinet is equipped with an instrument panel with indicator lights. When operating circuit breaker 60 inside the switch cabinet, the auxiliary circuit aviation plug should be plugged in. If energized, the test position indicator light on the instrument panel will illuminate. Close all cabinet doors, insert the key into the lock hole of the cabinet door, lock the cabinet door, and confirm that circuit breaker 60 is in the open position. At this time, insert the crank handle into the operating hole on the instrument panel and turn the crank handle clockwise until the crank handle is clearly obstructed and a crisp sound of the auxiliary switch switching is heard. At the same time, the working position indicator light on the instrument panel will illuminate. Then remove the crank handle. At this time, the main circuit is connected, and circuit breaker 60 is in the working position. It can be closed and opened through the control circuit.

[0050] Circuit breaker 60 deactivation procedure: First, confirm that circuit breaker 60 is in the open position. Insert the crank handle and turn it counterclockwise until the handle is obstructed and a clear sound of the auxiliary radiator switch switching is heard. Circuit breaker 60 will then return to the test position. At this point, the main circuit is completely disconnected, and the cabinet door is closed. When removing circuit breaker 60 from the switch cabinet, first ensure that circuit breaker 60 is in the test position, and then disconnect the auxiliary circuit aviation plug. Push the 10kV switch transfer trolley to the front of the switchgear. Raise the transfer platform 30 to a suitable position using the lifting and adjusting mechanism 40. Adjust the lateral adjustment mechanism 70 to move the transfer platform 30 left and right so that the positioning lock plate is inserted into the slot of the middle partition of the switchgear to lock the 10kV switch transfer trolley to the switchgear. Then manually connect the operating gripper 50 and the operating handle 62. Then start the automatic exit program of the circuit breaker 60. The control center 20 controls the longitudinal driver 52 to drive the lateral slide rail 54 to slide longitudinally on the longitudinal slide rail 53 and approach the circuit breaker 60. The control center 20 controls the lateral driver 51 to drive the operating gripper 50 to slide laterally so that the locking buckle 61 moves towards the switchgear to unlock it. The control center 20 controls the longitudinal driver 52 to drive the lateral slide rail 54 to slide longitudinally on the longitudinal slide rail 53 to move the circuit breaker 60 out of the switchgear. Then unlock the positioning lock plate and pull the 10kV switch transfer trolley outward.

[0051] It should be noted that the frame 10 is also equipped with a support plate 80. The transfer platform 30 is slidably mounted on the support plate 80. The lifting and adjusting mechanism 40 is used to drive the support plate 80 to lift and lower, thereby adjusting the height of the transfer platform 30. The support plate 80 is equipped with a laterally extending track 81. The transfer platform 30 is slidably mounted on the track 81. The lateral adjusting mechanism 70 is used to drive the transfer platform 30 to move laterally along the track 81. The lifting and adjusting mechanism 40 includes a lifting screw and a lifting nut. The lifting nut and the lifting screw are threaded together. The lifting screw is fixedly connected to the frame 10. The lifting nut is connected to the support plate 80 through a bearing. Rotating the lifting nut drives the support plate 80 to lift and lower. The lateral adjusting mechanism 70 is a linear motor. The linear motor is fixedly connected to the support plate 80. The output end of the linear motor is connected to the transfer platform 30. The output end of the linear motor extends and retracts to drive the transfer platform 30 to move laterally.

[0052] It should be noted that the circuit breaker 60 can also be installed on a handcart, and the operating gripper 50 can move the circuit breaker 60 by pulling the handcart.

[0053] In addition to the preferred embodiments described above, the present invention has other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
