Technical Field
[0001] This invention relates to the field of handling device technology, and in particular to a novel intelligent power distribution cabinet handling trolley. Background Technology
[0002] Intelligent distribution cabinet transport trolleys, professionally known as intelligent switchgear transfer trolleys or intelligent auxiliary transfer trolleys for switchgear, are mainly used for the safe handling, disassembly, installation, and positioning of switchgear equipment in power system substations and distribution rooms. They are used to transport the components of the intelligent distribution cabinet during the production process and to transport the entire intelligent distribution cabinet after production. There are various types of intelligent distribution cabinet transport trolleys available, but their core purpose is to improve the efficiency and safety of intelligent distribution cabinet handling.
[0003] In the production process of intelligent power distribution cabinets, a transport trolley is needed to transfer the boards that make up the power distribution cabinet. Existing transport trolleys are mostly composed of a loading frame, wheels, and a push handle. During the transport of the boards, the boards are neatly arranged on the loading frame of the transport trolley, and then the push handle is held to push the trolley to move. When encountering uphill or downhill slopes during the transport process, the transport trolley will be tilted. At this time, the center of gravity of the transport trolley and the boards will shift, making the transport trolley more likely to tip over. Once the transport trolley tip over, it will not only damage the boards and the transport trolley, but also cause injury to the workers. Summary of the Invention

Detailed Implementation
[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0021] Example 1 A new type of intelligent power distribution cabinet handling trolley, such as Figures 1-3 As shown, the system includes a chassis plate 1, a push handle 2 fixedly connected to the left side of the chassis plate 1, a movable plate 3 hinged to the chassis plate 1, and a frame 4 fixedly connected to the upper side of the movable plate 3. The frame 4 is used to separate the panels. When the frame 4 is removed, the intelligent power distribution cabinet can be directly placed on the movable plate 3 for transport. The chassis plate 1 is rotatably connected to two axles 5, and two wheels 6 are fixedly connected to the axles 5. The chassis plate 1 is rotatably connected to two threaded rods 7, and the threaded rods 7 are threadedly connected to transmission components 8. The transmission components 8 are slidably and rotatably connected to the movable plate 3. When the threaded rods 7 rotate, the height of the transmission components 8 can be adjusted, thereby changing the angle between the movable plate 3 and the chassis plate 1. The chassis plate 1 is fixedly connected to a motor 9, and the output shaft of the motor 9 is driven by a pulley belt to rotate the two threaded rods 7. The threads of the two threaded rods 7 are in opposite directions, which is used to drive the movable plate 3 to rotate. When the output shaft of the motor 9 drives the threaded rods 7 to rotate through the pulley belt, the two transmission components 8 can move in opposite directions.
[0022] like Figure 3 and Figure 4 As shown, a rotating component 10 is rotatably connected to the chassis plate 1, and a swing rod 11 is fixedly connected to the rotating component 10. The swing rod 11 is made of conductive material, and a weight 12 is fixedly connected to the lower side of the swing rod 11. The rotation axis of the rotating component 10 and the rotation axis of the movable plate 3 are on the same straight line.
[0023] like Figure 3 and Figure 4 As shown, two power sources 13 are fixedly connected to the chassis plate 1. Two first metal plates 14 are fixedly connected to the lower side of the movable plate 3. The opposing sides of the two first metal plates 14 are provided with inclined surfaces. A second metal plate 15 is fixedly connected to the upper side of the swing rod 11. A metal column 16 is fixedly connected to the second metal plate 15. The metal column 16 is used to connect with the first metal plate 14 to form a passage. The metal column 16 moves along the inclined surface of the first metal plate 14. The second metal plate 15 deforms and gradually increases the pressure between the metal column 16 and the first metal plate 14, thereby maintaining the contact between the two. One electrode of the motor 9 is electrically connected to a first wire 17. The first wire 17 is a three-way wire. The first wire 17 is electrically connected to different electrodes of the two power sources 13 at the same time. The other electrode of the motor 9 is electrically connected to the swing rod 11 by a second wire 18. The first metal plate 14 is electrically connected to the other electrode of the adjacent power source 13 by a third wire 19. When the metal column 16 contacts different first metal plates 14, the output shaft of the motor 9 rotates in different directions. The second metal sheet 15 is made of elastic material and is used to make the metal column 16 fit tightly against the first metal sheet 14.
[0024] like Figure 1 and Figures 5-7 As shown, a first braking component 20 is slidably connected to the vehicle floor 1. A first spring 21 is provided between the first braking component 20 and the vehicle floor 1. The first braking component 20 is used to stop the rotating component 10. The first spring 21 is always in a compressed state, so that when the vehicle floor 1 moves on flat ground, the rotating component 10 will not rotate due to sudden movement or stopping. A brake cable 22 is fixedly connected to the first braking component 20. A cable conduit 23 is fixedly connected to the vehicle floor 1. A fixing member 24 is fixedly connected to the push handle 2. The cable conduit 23 is fixedly connected to the fixing member 24. A handle 25 is rotatably connected to the fixing member 24. The brake cable 22 passes through the cable conduit 23 and is fixedly connected to the handle 25. By rotating the handle 25, the first braking component 20 can be separated from the rotating component 10.
[0025] When using this device, first push it to the power distribution cabinet material storage area, then move the materials onto the movable plate 3, and separate the materials using the plate rack 4. After the materials are loaded, push the device using the push handle 2. The device moves from right to left. When encountering an uphill slope, squeeze the handle 25. The handle 25 pulls the brake cable 22, which in turn pulls the first braking element 20. The first braking element 20 moves upward, separates from the rotating element 10, and compresses the first spring 21. During the uphill process, the left side of the vehicle floor 1 gradually rises. The swing rod 11 remains vertical under the action of the weight 12. At this time, the rotating element 10 rotates counterclockwise relative to the vehicle floor 1. The movable plate 3 and the vehicle floor 1 remain in their original state due to the fixation of the threaded rod 7. Therefore, the rotating element 10 also rotates relative to the movable plate 3. The swing rod 11 drives the second metal plate 15 to rotate, and the second metal plate 15 drives the metal column 16 to rotate. The metal column 16 is brought into contact with the left-side plate frame 4, forming a circuit. Current flows from the left-side power source 13, through the first wire 17 to the motor 9, then through the second wire 18 to the swing rod 11, then through the second metal plate 15 to the metal column 16, and then back to the left-side power source 13 through the first metal plate 14 and the third wire 19. This causes the output shaft of the motor 9 to rotate clockwise, and drives the threaded rod 7 to rotate via the pulley belt. At this time, the threaded rod 7 on the left causes the left-side transmission component 8 to move down, and the threaded rod 7 on the right causes the right-side transmission component 8 to move up. The two transmission components 8 drive the movable plate 3 to rotate counterclockwise, gradually approaching horizontality. When the movable plate 3 returns to a horizontal state, the movable plate 3 drives the first metal plate 14 to rotate until it separates from the metal column 16. At this time, the circuit is broken, the motor 9 stops working, thus maintaining the current state of the movable plate 3 and restoring the center of gravity of the plate on it to the middle, preventing the center from tipping over.
[0026] When the device moves from the slope to flat ground, the left side of the chassis 1 gradually moves down, restoring the chassis 1 to a horizontal state. At this time, the chassis 1 drives the movable plate 3 to rotate, and the rotating component 10 rotates clockwise relative to the movable plate 3, causing the metal column 16 to contact the first metal plate 14 on the right. At this time, the second metal plate 15, the metal column 16, the third wire 19 on the right, the power supply 13 on the right, the first wire 17, the motor 9, the second wire 18, and the swing rod 11 form a circuit, causing the output shaft of the motor 9 to reverse. At this time, the output of the motor 9... The output shaft drives two threaded rods 7 to rotate via a pulley and belt. The threaded rod 7 on the left moves the transmission component 8 on the left upward, and the threaded rod 7 on the right moves the transmission component 8 on the right downward. This causes the movable plate 3 to return to a horizontal state after the device reaches the flat ground. After the movable plate 3 returns to a horizontal state, the passage is disconnected. At this time, the handle 25 can be released. The first braking component 20 moves downward under the action of the first spring 21, so that the first braking component 20 stops the rotating component 10, thus preventing the weight 12 from shaking due to sudden start or stop when it is on the flat ground.
[0027] Example 2 Based on Example 1, such as Figure 2 and Figure 8 As shown, a ratchet 26 is fixedly connected to the left axle 5, and a slide rail 27 is fixedly connected to the lower side of the movable plate 3. A first sliding member 28 is slidably connected to the bottom plate 1. A pawl 29 is rotatably connected to the first sliding member 28. The pawl 29 is used to make the ratchet 26 rotate in one direction. Initially, the pawl 29 does not contact the ratchet 26. When going uphill, the ratchet 26 rotates normally. When an accident occurs during the uphill process and the bottom plate 1 slides down, the ratchet 26 is stuck by the pawl 29 and cannot rotate, thereby preventing the bottom plate 1 from sliding down. An elastic piece 30 is provided between the pawl 29 and the first sliding member 28. The elastic piece 30 is stretched when the pawl 29 rotates, and after the pawl 29 is no longer squeezed, the elastic piece 30 pulls the pawl 29 back to its original position. A second sliding member 31 is slidably connected to the first sliding member 28. The second sliding member 31 is slidably and rotatably connected to the slide rail 27.
[0028] like Figure 8 As shown, a second spring 32 is provided between the first sliding member 28 and the second sliding member 31. The second spring 32 is used to keep the pawl 29 in contact with the ratchet 26. When the vehicle floor 1 moves from the slope to the flat ground, even if the second sliding member 31 gradually moves upward, the pawl 29 can still maintain contact with the ratchet 26 until the vehicle floor 1 moves to the flat ground.
[0029] like Figure 2 , Figure 3 and Figure 5As shown, a third sliding member 33 is slidably connected to the left side of the vehicle floor 1. The third sliding member 33 consists of a flat plate and an L-shaped rod. A second braking member 34 is fixedly connected to the third sliding member 33. The second braking member 34 is semi-circular and uses friction to decelerate the left axle 5, thereby preventing the vehicle floor 1 from going too fast during the downhill process. A tension spring 35 is provided between the third sliding member 33 and the movable plate 3.
[0030] When the device moves uphill, the left side of the chassis 1 and the left side of the movable plate 3 move closer to each other. The movable plate 3 drives the slide rail 27 to move downward, and the slide rail 27 drives the second sliding member 31 to move downward. The second sliding member 31 pushes the first sliding member 28 to move through the second spring 32. The first sliding member 28 drives the pawl 29 to move, so that the pawl 29 contacts the ratchet 26. During the uphill movement, the left axle 5 drives the ratchet 26 to rotate forward. The ratchet 26 squeezes the pawl 29, causing the pawl 29 to rotate and stretch the elastic sheet 30. If the device loses thrust and slides down during the movement, the axle 5 drives the ratchet 26 to rotate backward. At this time, the ratchet 26 is stuck by the pawl 29 and cannot rotate, thus achieving the effect of stopping. When the device reaches flat ground, the movable plate 3 drives the slide rail 27 to move upward, and drives the pawl 29 and the ratchet 26 to separate.
[0031] When the device is going downhill, the left side of the chassis 1 and the left side of the movable plate 3 move away from each other. The movable plate 3 pulls the third sliding member 33 upward through the tension spring 35. The third sliding member 33 drives the second braking member 34 to contact the axle 5, thereby slowing down the rotation of the axle 5 and preventing the device from going downhill faster and faster. The greater the angle of the slope, the greater the distance between the chassis 1 and the movable plate 3, which in turn increases the tension of the tension spring 35 and the friction of the second braking member 34 against the axle 5, resulting in a better deceleration effect. When the device goes from downhill to flat ground, the distance between the chassis 1 and the movable plate 3 is restored, the tension of the tension spring 35 disappears, and the second braking member 34 separates from the axle 5.
[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
