[0002] As is well known, the safety and reliability of the operation and maintenance of industrial electrical equipment is a primary concern for power supply departments.

[0003] Specifically, in the industrial power electrical equipment sector, typically using 10kV power systems, indoor AC withdrawable switchgear is a complete set of power distribution equipment for single busbar and single busbar segmented systems. This type of switchgear can be used in power plants, power transmission from small and medium-sized generators, power distribution in industrial and mining enterprises, and power receiving, transmission, and starting of large high-voltage motors in secondary substations of power systems. It plays a crucial role in controlling, protecting, and monitoring power equipment, ensuring smooth operation of power systems and protecting electrical equipment.

This allows for vertical and horizontal lifting and pulling operations of the components to be transferred, such as the trolley or instrument transformer, into the frame. Before the transfer cart and the rotary disconnect circuit breaker are pulled into the frame, the locking assembly can lock the electrical cabinet of the rotary disconnect circuit breaker, ensuring mutual fixation between the frame and the electrical cabinet. Subsequently, the gripping assembly grips the trolley or instrument transformer into the frame, enabling the transfer and maintenance of the trolley or instrument transformer. The operation is convenient, time-saving, labor-saving, and provides accurate positioning and rapid adjustment.

[0045] refer to Figure 1-12b According to one embodiment of the present invention, an intelligent transfer vehicle 100 is provided, which includes...

[0046] The frame 10 includes a base 12, columns 14 arranged longitudinally from the four corners of the base 12, and a pair of longitudinal beams 18 and a pair of transverse beams 16 connecting two adjacent columns 14 at their top ends. The pair of longitudinal beams 18 are arranged in parallel, the pair of transverse beams 16 are arranged in parallel, and each longitudinal beam 18 is perpendicular to the adjacent transverse beam 16.

[0047] The lifting assembly 20 includes a motor 24 mounted on one of the crossbeams 16, a drive shaft 26 disposed between two columns 14 at both ends of the crossbeam 16 and driven to rotate by the motor 24, a longitudinal drive belt 268 disposed at both ends of the drive shaft 26 and driven by the drive shaft 26 to rotate along the height direction of the corresponding column 14, and a fixed frame 28 fixed to the longitudinal drive belt 268 and capable of lifting and lowering along the height direction of the corresponding column 14.

[0048] The track assembly 60 includes a track mounting frame 62 fixed to a corresponding mounting frame 28 and a track 64 disposed between the two track mounting frames 62, one end of the track 64 having an extension end 642 extending beyond the frame 10;

[0049] The push-pull assembly 70 includes a push-pull motor 72 fixed on one of the track mounting brackets 62 and a horizontal conveyor belt 74 driven by the push-pull motor 72 to rotate along the length of the track 64.

[0050] The gripping assembly 30 includes a movable beam 32 fixed to the horizontal conveyor belt 74 and two first gripping mechanisms 36 and a second gripping mechanism 34 disposed on the movable beam 32.

[0051] A locking component 40 is provided at the end of the protruding end 642; and

[0052] An electrical control box 80 is installed on the frame 10 to control the lifting assembly 20, the push-pull assembly 70, the gripping assembly 30, and the locking assembly 40.

[0053] In the above embodiments, the base 12 of the frame 10 can be constructed by connecting multiple, for example, four, profiles of suitable length, such as aluminum alloy profiles or stainless steel profiles. Considering that the entire intelligent transfer vehicle 100 needs to transfer heavy current transformers or circuit breakers inside the electrical switch cabinet, it needs to have a certain load capacity. Therefore, the base 12 needs to have sufficient structural strength, so it is preferable to use steel, such as stainless steel, to form the base 12. Multiple profiles can be fixed to each other in an appropriate way, such as riveting, threaded connection, or welding. In another embodiment, the frame 10 adopts a square tube integral welded structure, which ensures the strength of the entire vehicle body and meets the load-bearing requirements.

[0054] Preferably, in one embodiment, a motor mounting plate 22 is provided on one of the crossbeams 16, and the motor 24 is fixed on the motor mounting plate 22. Here, since the cross-sectional area of ​​the crossbeam 16 is much smaller than that of the motor 24, directly mounting the motor 24 to the crossbeam 16 may result in unsuccessful installation due to the limited mounting area, or even if installation is possible, the connection strength after installation may be insufficient, easily causing the motor 24 to shift position during operation, thus failing to accurately transmit power to the drive shaft 26. Adding the motor mounting plate 22 effectively increases the contact area for motor 24 installation, thus making the installation of the motor 24 more secure and stable, ultimately enabling accurate power transmission to the drive shaft 26.

[0055] In another embodiment, the motor 24 has a horizontal drive shaft 242 on which a drive gear 244 is disposed; correspondingly, a driven gear 262 meshing with the drive gear 244 is disposed on the transmission shaft 26. Through the meshing of the two gears, the power output by the motor 24 is transmitted to the transmission shaft 26, causing the transmission shaft 26 to rotate.

[0056] Preferably, upper drive wheels 264 are provided at both ends of the drive shaft 26 near the corresponding columns 14, and lower drive wheels 266 are provided at the bottom of the corresponding columns 14 near the base 12. The longitudinal drive belt 268 is wound between the corresponding upper drive wheels 264 and lower drive wheels 266. When the drive shaft 26 rotates, it drives the upper drive wheels 264 to rotate together, thereby causing the longitudinal drive belt 268 to perform longitudinal rotational motion.

[0057] In one embodiment, reference Figure 8 The fixed frame 28 can rise and fall along the height direction of the column 14 as the longitudinal transmission belt 268 rotates. The fixed frame 28 has a base plate 282 and side clamping arms 284 disposed at both ends of the base plate 282. The two side clamping arms 284 are respectively disposed at the two ends of the corresponding column 14 so that when the fixed frame 28 moves up and down, it does not deviate from the column 14, thus preventing difficulty in raising and lowering. Here, locking blocks 286 are longitudinally disposed on the base plate 282. The longitudinal transmission belt 268 is attached to the surface of the base plate 282 away from the two side clamping arms 284 and is clamped to the surface by the locking blocks 286, so that the longitudinal transmission belt 268 moves up and down together with the fixed frame 28. It should be noted that multiple locking blocks 286 can be provided. For example, in one embodiment, two vertically distributed locking blocks 286 are provided to further clamp the longitudinal transmission belt 268 and prevent the longitudinal transmission belt 268 from slipping relative to the fixed frame 28 during the raising and lowering process, thus preventing it from failing to raise and lower normally.

[0058] It should be noted that although only one lifting component 20 is described in the above embodiment, in order to ensure a smooth lifting process, another lifting component 20 can be additionally provided, which is set on another crossbeam 16 and the corresponding column 14. This can effectively prevent the equipment from jamming.

[0059] In one embodiment, a first drive wheel 722 is provided on the push-pull motor 72; a bracket 726 is provided on the track mounting frame 62 on which the push-pull motor 72 is not provided, and a second drive wheel 724 is provided on the bracket 726; the horizontal conveyor belt 74 is wound between the first drive wheel 722 and the second drive wheel 724.

[0060] Similarly, in addition to the two lifting components 20 described above, a push-pull component 70 can be added to ensure a smoother horizontal pushing and pulling process. This component is located on a corresponding part of the other lifting component 20. This can also effectively prevent the equipment from jamming.

[0061] The second gripping mechanism 34 is used to grip the insulating board on the electrical switch cabinet so as to move the heavy insulating board into the intelligent transfer vehicle 100. It includes a base 342 fixed on the moving beam 32, a cantilever 344 provided at one end of the base 342, a second hook plate 346 rotatably provided at the other end of the base 342, and a second electric push rod 348 that is pivotally connected to the top end of the cantilever 344 and the second hook plate 346. A second slot 3462 is formed in the second hook plate 346.

[0062] Because the second gripping mechanism 34 has the aforementioned structure, when it is necessary to grip and drag the insulating board into the intelligent transfer cart 100, firstly, the intelligent transfer cart 100 moves next to the electrical switch cabinet, causing the locking component 40 to hook into the corresponding lock hole on the electrical switch cabinet. This ensures that the intelligent transfer cart 100 and the electrical switch cabinet are temporarily fixed to each other to ensure operational safety. Subsequently, when an external drive signal is applied to the second electric push rod 348, it pushes the second hook plate 346 to rotate downwards, causing the second slot 3462 to hook into the corresponding part of the insulating board. Then, under the action of the external drive signal, as the push-pull component 70 moves, the gripping action of the insulating board is realized.

[0063] Two first gripping mechanisms 36 are distributed on both sides of the second gripping mechanism 34, used to grip circuit breaker trolleys or current transformer trolleys to move them into the intelligent transfer vehicle 100. Each first gripping mechanism 36 includes a swing rod 366 rotatably sleeved on a lead screw 362 and a first hook plate 368 disposed at the end of the swing rod 366, with a first slot 3682 formed on the first hook plate 368; the lead screw 362 spans both ends of the moving beam 32 and is arranged parallel to the moving beam 32; a synchronizing rod 369 is disposed in the middle of the swing rod 366; the top of the cantilever 344 is rotatably connected to one end of a first electric push rod 367, and the other end of the first electric push rod 367 is rotatably connected to the synchronizing rod 369.

[0064] Similarly, since the first gripping mechanism 36 has the above-described structure, when it is necessary to grip and drag the circuit breaker trolley or current transformer trolley into the intelligent transfer cart 100, firstly, the intelligent transfer cart 100 moves next to the electrical switch cabinet, so that the locking component 40 hooks into the corresponding lock hole on the electrical switch cabinet. This ensures that the intelligent transfer cart 100 and the electrical switch cabinet are temporarily fixed to each other to ensure operational safety. Next, when the external drive signal acts on the first electric push rod 367, it pushes the synchronizing rod 369 to produce a positional offset. Since the synchronizing rod 369 passes through the swing rod 366, the swing rod 366 swings around the lead screw 362, thereby causing the first hook plate 368 to flip and the first slot 3682 to hook with the corresponding part of the circuit breaker trolley or current transformer trolley. Then, under the action of the external drive signal, as the push-pull component 70 moves, the first hook plate 368 hooks the circuit breaker trolley or current transformer trolley and moves it, thereby removing it from the electrical switch cabinet.

[0065] Preferably, a threaded sleeve 364 is fitted onto the lead screw 362, and the threaded sleeve 364 is axially connected to the rocker arm 366. Drive motors 361 are connected to both ends of the lead screw 362. When the drive motors 361 operate, they drive the lead screw 362 to rotate. Since the lead screw 362 spans both ends of the slide rail 38, it cannot move axially on its own. Therefore, the lead screw 362 only rotates without axial movement. The threaded sleeve 364 is threadedly connected to the lead screw 362, thus causing the threaded sleeve 364 to move axially, and simultaneously driving the two rocker arms 366 to move towards or away from each other along the axial direction of the lead screw 362. Here, when the rocker arms 366 of the two first gripping mechanisms 36 approach each other due to the relative movement between the lead screw 326 and the threaded sleeve 364, the corresponding two second slots 3682 also approach each other, thereby unlocking the circuit breaker or current transformer trolley.

[0066] More preferably, a slide rail 38 is provided on the moving beam 32, and a slider 365 is provided on the slide rail 38. The slider 365 is fixed to the sliding sleeve 364 by a connecting rod 363. When the swing arm 366 moves axially, the above-mentioned slide rail and slider cooperation is adopted to ensure the moving accuracy and stability. Specifically, since the sliding between the slider 365 and the sliding sleeve 364 is a precision sliding, and the slider 365 is fixedly connected to the sliding sleeve 364, the circumferential movement of the sliding sleeve 364 is also very smooth and stable. As a result, the swing arm 366 connected to the sliding sleeve 364 also moves smoothly and stably, thereby improving the stability and reliability of the operation.

[0067] The locking component 40 is used to lock the electrical switch cabinet before the grabbing operation, that is, to fix the entire intelligent transfer vehicle 100 and the electrical switch cabinet together first, so as to avoid the danger caused by the reaction force during the grabbing process, such as the equipment falling to the ground due to the unstable grabbing.

[0068] In one embodiment, the locking assembly 40 includes a mounting base 42, a direct-acting cylinder 44 disposed within the mounting base 42, and a locking hook body 41 that swings up and down driven by the direct-acting cylinder 44.

[0069] When an external drive signal is received, the direct-acting cylinder 44 drives the lock hook body 41 to swing up and down within a certain angle, thereby realizing the locking or unlocking of the lock hook body 41 and the electrical switch cabinet.

[0070] Preferably, one end of the mounting base 42 is provided with a bearing 422, and a pin hole 4222 is provided on the bearing 422; the direct-acting cylinder 44 is fixed to the mounting base 42 by passing a pin 424 through the pin hole 4222 and the direct-acting cylinder 44.

[0071] Preferably, a rotating seat 46 is provided at the other end of the mounting base 42, and a push block 48 is provided inside the rotating seat 46. One end of the push block 48 is connected to the movable rod 442 of the direct-acting cylinder 44, and the other end of the push block 48 is located at the bottom of the locking hook body 41. The locking hook body 41 is pivotally mounted inside the rotating seat 46. When the movable rod 442 of the direct-acting cylinder 44 extends or retracts, the push block 48 extends or retracts synchronously. Since the push block 48 is located at the bottom of the locking hook body 41, it can cause the locking hook body 41 to swing up and down relative to the rotating seat 46 to a certain extent.

[0072] More preferably, the rotating seat 46 has a first pivot hole 462; the locking hook body 41 has a body 411 and a second pivot hole 412 formed at one end of the body 411, and the locking hook body 41 is pivotally mounted in the rotating seat 46 by passing a first pivot 424 through the first pivot hole 462 and the second pivot hole 412 in sequence.

[0073] More preferably, the other end of the push block 48 is provided with a movable groove 482, and the two sides of the movable groove 482 are provided with third pivot holes 4822; the other end of the body 411 forms a hook portion 413, and the bottom of the body 411 is provided with a protrusion 414, and a sliding groove 4142 is provided in the protrusion 414 at an inclination relative to the upper surface of the body 411; the protrusion 414 is inserted into the movable groove 482, and the rotating shaft (not shown) is inserted into the third pivot hole 4822 and the sliding groove 4142.

[0074] In the above embodiment, since the slide groove is formed at an inclination relative to the upper surface of the body, when the movable rod 442 of the direct-acting cylinder 44 extends or retracts, it drives the push block 48 to extend or retract as well. The sliding of the rotating shaft in the slide groove causes the locking hook body 41 to swing up and down a certain range relative to the rotating seat 41. For example, when the movable rod of the direct-acting cylinder does not extend or retract, the locking hook body is in a horizontal state and is not hooked in the corresponding lock hole on the electrical switch cabinet. When the movable rod of the direct-acting cylinder extends, the movement of the push block causes the locking hook body to be lifted (swinging upward at a certain angle and maintaining at that angle), thereby hooking in the corresponding lock hole on the electrical switch cabinet. This ensures that the intelligent transfer vehicle and the electrical switch cabinet are temporarily fixed to each other to ensure operational safety.

[0075] More preferably, the locking assembly 40 further includes a baffle 43 disposed in front of the rotating seat 46, the baffle 43 having a window 432, and the hook 413 extending out from the window 432. The purpose of the baffle is to facilitate a secure fit between the intelligent transfer vehicle and the electrical switch cabinet when the vehicle approaches, allowing the hook to extend and enter the corresponding lock hole to achieve a locking action.

[0076] In one embodiment, the intelligent transfer vehicle 100 further includes a walking assembly 50 for moving the entire frame 10. The walking assembly 50 includes casters 52 rotatably mounted on the base 12 and a drive wheel 54 that can drive the casters 52 to move.

[0077] For example, the drive wheel 54 is mounted vertically between two adjacent columns 14. When the drive wheel 54 moves downward to a certain extent, it begins to contact the ground. Then, as the drive wheel 54 rolls relative to the ground, it provides a moving force to the entire intelligent transfer vehicle 100, allowing the intelligent transfer vehicle 100 to move on the ground.

[0078] In one embodiment, a fixing plate 56 is horizontally arranged between two adjacent columns 14, and an electric cylinder 542 is provided at the bottom of the fixing plate 56 to cause the drive wheel 54 to move up and down.

[0079] For example, the electric cylinder 542 has an electric cylinder body 5422 and an electric cylinder shaft 5424 extending from one end of the electric cylinder body 5422. The electric cylinder shaft 5424 is mounted on the fixed plate 56, and the electric cylinder body 5422 is fixedly connected to the drive steering wheel 54. When an external drive signal is applied to the electric cylinder 542, the electric cylinder shaft 5424 extends relative to the electric cylinder body 5422. Since the electric cylinder shaft 5424 is fixed to the fixed plate 56, and the fixed plate 56 itself is fixed relative to two adjacent columns 14, the electric cylinder body 5422 moves downward. Correspondingly, the drive steering wheel 54, which is fixedly connected to the electric cylinder body 5422, also moves downward and contacts the ground. As the drive steering wheel 54 rolls relative to the ground, the intelligent transfer vehicle 100 moves as a whole, thereby realizing the transportation of the equipment to be repaired, such as current transformers and circuit breakers, on the intelligent transfer vehicle 100 to the destination for maintenance.

[0080] Preferably, the electric cylinder body 5422 is fixed to one surface of the steering wheel mounting plate 59, while the drive steering wheel 54 is mounted on the other opposite surface of the steering wheel mounting plate 59. In this way, the power of the electric cylinder body 5422 is transmitted to the drive steering wheel 54 through the steering wheel mounting plate 59, causing it to contact the ground.

[0081] Further preferably, the walking assembly 50 further includes a side plate 51, on which a first support wall 514 and a second support wall 512 located below the first support wall 514 are disposed; a guide rod 516 is disposed between the first support wall 514 and the second support wall 512, the guide rod 516 passing through the steering wheel mounting plate 58, so that the steering wheel mounting plate 58 is slidably disposed between the first support wall 514 and the second support wall 512; a compression spring 53 is disposed between the steering wheel mounting plate 58 and the second support wall 512 and sleeved on the guide rod 516. The function of the compression spring 53 is to reduce the vibration when the drive steering wheel 54 rolls relative to the ground. For example, if the intelligent transfer vehicle 100 moves bumpily due to uneven road surface, which may damage the equipment, the compression spring 53 can play a shock absorption role, thereby making the walking process more stable and smooth.

[0082] Preferably, the electrical control box 80 is fixed to one side of the frame 10 via a strip-shaped mounting base to improve space utilization and avoid occupying the installation space along the push-pull direction of the frame. The electrical control box 80 contains a control module and control buttons for controlling the lifting assembly 20, the push-pull assembly 70, the gripping assembly 30, and the locking assembly 40, as well as a touch screen display 81, a three-color alarm light 82, a fan, a voice announcer, or a power supply. The touch screen display 81 is tilted at the top of the electrical control box for easy data input or reading by the operator, and the three-color alarm light 82 is mounted on the side wall of the electrical control box.

[0083] In summary, the intelligent transfer vehicle provided by this utility model can transfer circuit breaker trolleys, insulation boards, and current transformer trolleys in manual and semi-automatic modes. The transfer operation of circuit breaker trolleys and current transformer trolleys is realized by operating the control buttons and touch screen on the electrical control box.
