[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

The first hinged rod 24 and the second hinged rod 25 in the present invention may be multiple, and multiple first hinged rods 24 and second hinged rods 25 are connected to each other.

[0021] As a specific implementation method, in order to solve the problem that the height of the trolley transfer cart cannot be adjusted or is inconvenient to adjust in the prior art, this embodiment provides a 10kV trolley switch transfer device. The trolley achieves height adjustability through a series of sophisticated structural designs, thereby adapting to the trolley transfer requirements of different switch cabinets, and there is no need to make a specific transfer trolley for each individual switch cabinet. Specifically, the transfer trolley in this embodiment includes a base plate 10, and mounting plates 21 are provided on both sides of the base plate 10, and a first slide groove 22 is provided on one side of each mounting plate 21. In the first slide groove 22, a first slide rod 23 is slidably arranged, and the other side of the mounting plate 21 is hinged with a first hinged rod 24. The two ends of the first slide rod 23 are hinged with a second hinged rod 25, and the center of the first hinged rod 24 is hinged to the center of the second hinged rod 25. Such a design enables the first slide bar 23 to slide synchronously with the second hinged rod 25 when sliding in the first slide groove 22, and the second hinged rod 25 can rotate relative to the first hinged rod 24 around the center, providing the height adjustment capability of the transfer trolley. The addition of the drive assembly 30 further enhances the functionality of the transfer trolley, which can push the second hinged rod 25 to slide in the first slide groove 22, thereby realizing the height adjustment of the support plate 26. The support plate 26 is hinged at one end of the second hinged rod 25 away from the bottom plate 10, and the bottom plate 10 is provided with a second slide groove 22, and a second slide bar is slidably arranged in the second slide groove 22, and one end of the first hinged rod 24 away from the bottom plate 10 is hinged on the second slide bar. The support plate 26 is used to support a trolley, and two mounting rails 27 are provided on it, and the trolley can be slidably arranged on these mounting rails 27. Through the above design, the transfer trolley can not only adapt to trolleys of different heights, but also provide stable support during transportation to prevent the trolley from tipping over. This height-adjustable design makes the transfer trolley more versatile and flexible, and can be applied to switch cabinet trolleys of various models and sizes, thereby solving the problem in the prior art of requiring a separate transfer trolley to be made for each switch cabinet, and greatly improving the practicality and economy of the transfer trolley.

[0022] like Figure 4 As shown, as a further technical solution, the driving assembly 30 includes: The bottom plate 10 is provided with a first piston rod 31, the telescopic end of the first piston rod 31 is provided on the first sliding rod 23, the first piston rod 31 has a first telescopic cavity 311, and also includes an oil storage cavity 32 provided on the bottom plate 10, the oil storage cavity 32 has an oil outlet 321, and a one-way valve 33 is provided at the oil outlet 321, the oil storage cavity 32 is communicated with the first telescopic cavity 311 through the oil outlet 321, and also includes a second piston rod 34 provided on the bottom plate 10, the second piston rod 34 has a second telescopic cavity 341, and the oil storage cavity 32 is communicated with the second telescopic cavity 341 through the oil outlet 321; After the first piston rod 31 moves away from the oil storage cavity 32, the one-way valve 33 is in an open state, and after the first piston rod 31 moves toward the oil storage cavity 32, the one-way valve 33 is in a closed state; The oil storage cavity 32 further has a pressure relief port 322 , which is in communication with the first telescopic cavity 311 , and also includes an adjustment member 35 disposed between the oil storage cavity 32 and the first telescopic cavity 311 , and the adjustment member 35 is used to open or close the pressure relief port 322 .

[0023] In this embodiment, we further optimize the drive assembly 30 of the 10KV trolley anti-dumping transfer trolley to improve its operational flexibility and safety. The core of the drive assembly 30 includes two piston rods and a precisely designed hydraulic system.

[0024] Specifically, a first piston rod 31 is installed on the bottom plate 10, and its telescopic end is connected to the first slide bar 23, which constitutes the main part of the drive assembly 30. A first telescopic cavity 311 is designed inside the first piston rod 31 for storing hydraulic oil. Correspondingly, an oil storage cavity 32 is also provided on the bottom plate 10 as a reserve reservoir for hydraulic oil. The oil storage cavity 32 is designed with an oil outlet 321, and a one-way valve 33 is installed at the oil outlet 321 to ensure that the oil can only flow from the oil storage cavity 32 to the first telescopic cavity 311 to prevent backflow.

[0025] When the first piston rod 31 extends outward, that is, moves away from the oil storage cavity 32, the one-way valve 33 opens, allowing hydraulic oil to flow from the oil storage cavity 32 into the first telescopic cavity 311, pushing the piston rod to extend, thereby driving the first slide rod 23 and the second hinge rod 25 to slide in the slide groove 22, and realizing the height adjustment of the support plate 26. On the contrary, when the first piston rod 31 contracts inward, that is, moves toward the oil storage cavity 32, the one-way valve 33 closes to prevent the oil from flowing back, ensuring that the pressure in the first telescopic cavity 311 is maintained.

[0026] In order to further control the pressure of the hydraulic system, the oil storage cavity 32 is also designed with a pressure relief port 322, which is connected to the first telescopic cavity 311. The function of the pressure relief port 322 is to release the pressure when the system pressure is too high to prevent the system from being damaged. Between the oil storage cavity 32 and the first telescopic cavity 311, we installed an adjustment member 35, which can open or close the pressure relief port 322 as needed. In this way, the operator can accurately control the pressure of the hydraulic system according to the actual use situation, ensuring the stability and safety of the transfer trolley under different loads and operating conditions.

[0027] With this design, our drive assembly 30 not only provides precise height adjustment capabilities, but also enhances the safety performance of the system, allowing the 10KV trolley anti-dumping transfer trolley to work reliably under various operating conditions.

[0028] like Figure 6 As shown, as a further technical solution, the adjusting member 35 includes: The bottom plate 10 is provided with a third piston rod 36, and the third piston rod 36 is provided with an abutment ball 37; The pressure relief port 322 has an abutting inclined surface 3221 , and the abutting ball 37 is used to move with the third piston rod 36 . After the third piston rod 36 moves, it is used to drive the abutting ball 37 to abut or not abut the abutting inclined surface 3221 .

[0029] In this embodiment, we have made an innovative design to the adjustment member 35 to achieve precise control of the pressure relief port 322. The core of the adjustment member 35 is a third piston rod 36, which is arranged on the bottom plate 10 and has an abutment ball 37 mounted thereon. This design allows the abutment ball 37 to move with the movement of the third piston rod 36, thereby controlling the opening and closing state of the pressure relief port 322.

[0030] The specific operation is as follows: the pressure relief port 322 is designed with an abutment slope 3221. When the third piston rod 36 extends outward, the abutment ball 37 moves accordingly and contacts the abutment slope 3221, thereby closing the pressure relief port 322 to prevent the hydraulic oil from flowing out of the first telescopic cavity 311 and maintain the system pressure. On the contrary, when the third piston rod 36 contracts inward, the abutment ball 37 leaves the abutment slope 3221, and the pressure relief port 322 opens accordingly, allowing the hydraulic oil to flow out of the first telescopic cavity 311, thereby releasing the system pressure.

[0031] This design allows the operator to precisely adjust the opening and closing of the pressure relief port 322 by controlling the movement of the third piston rod 36, thereby controlling the pressure of the hydraulic system. In actual operation, this adjustment method is very intuitive and responsive. The operator can adjust the state of the pressure relief port 322 in real time according to the working state and load condition of the trolley transfer trolley to ensure the stability and safety of the system.

[0032] As a further technical solution, the driving assembly 30 further includes a first foot pedal 38 hingedly arranged on the base plate 10 at the center and a second foot pedal 39 hingedly arranged on the base plate 10 at the center, and the first foot pedal 38 has a first foot pedal end 381 and a first hinge end 382, ​​the first foot pedal end 381 and the first hinge end 382 are respectively located at two ends of the first foot pedal 38, the first hinge end 382 is used to be hingedly arranged with the first piston rod 31, and the first foot pedal 38 is used to drive the second piston rod 34 to move in the second telescopic cavity 341 after swinging along the center on the base plate 10; The second foot pedal 39 has a second foot pedal end 391 and a second hinged end 392, and the second foot pedal end 391 and the second hinged end 392 are respectively located at the two ends of the second foot pedal 39, and the second hinged end 392 is used to be hinged with the second piston rod 34. After the second foot pedal 39 swings on the base plate 10 along the center, it is used to drive the third piston rod 36 to move, and in this scheme, elastic parts are provided at the first piston rod 31 and the second piston rod 34 to provide force for resetting the first foot pedal 38 and the second foot pedal 39.

[0033] In this embodiment, in order to improve the maneuverability and convenience of the 10KV anti-dumping transfer trolley, we further optimized the drive assembly 30 and introduced a pedal mechanism. Specifically, we hingedly set two pedals at the center of the bottom plate 10: a first pedal 38 and a second pedal 39.

[0034] The first foot pedal 38 is designed with a first foot pedal end 381 and a first hinge end 382, ​​which are respectively located at the two ends of the foot pedal. The first hinge end 382 is hingedly arranged with the first piston rod 31, so that when the operator steps on the first foot pedal 38, the foot pedal swings around the center point on the bottom plate 10, and this action can drive the first piston rod 31, and then push the second piston rod 34 to move in the second telescopic cavity 341. Such a design allows the operator to control the pressure of the hydraulic system through a simple foot pedal action to adjust the height of the support plate 26.

[0035] The second foot pedal 39 also has a second foot pedal end 391 and a second hinge end 392, which are also located at both ends of the foot pedal. The second hinge end 392 is hingedly arranged with the second piston rod 34. When the operator steps on the second foot pedal 39, the swing of the foot pedal will drive the third piston rod 36 to move. This action further controls the opening and closing state of the pressure relief port 322, because the third piston rod 36 is provided with an abutment ball 37, and its movement can control whether the abutment ball 37 contacts the abutment slope 3221 of the pressure relief port 322, thereby adjusting the pressure release of the hydraulic system.

[0036] The design of this foot pedal provides a direct and labor-saving way to control the hydraulic system of the transfer trolley, allowing the operator to easily adjust the height of the support plate 26 and the pressure of the hydraulic system without using additional tools or complicated operations. Such a design not only improves the efficiency of the operation, but also reduces the labor intensity during the operation, making the transfer trolley more user-friendly and suitable for various working environments and operating conditions. Through this foot pedal mechanism, we can ensure the stability and safety of the trolley during the transfer process, while improving work efficiency.

[0037] like Figure 2 As shown, as a further technical solution, the support plate 26 has a sliding groove 41, and the two mounting rails 27 each have a protrusion 42, and the protrusion 42 is slidably arranged in the sliding groove 41. After the protrusion 42 slides in the sliding groove 41, the two mounting rails 27 are moved closer to each other or away from each other; A first threaded rod 43 is threadedly disposed on the protrusion 42 , and the first threaded rod 43 is rotatably disposed on the supporting plate 26 . After the first threaded rod 43 rotates on the supporting plate 26 , it is used to drive the two protrusions 42 to move closer to or away from each other.

[0038] In this embodiment, we innovate the design of the support plate 26 to achieve dynamic adjustment of the mounting rails 27 so that it can adapt to carts of different sizes. A sliding groove 41 is specially designed on the support plate 26, and protrusions 42 are provided on both mounting rails 27. These protrusions 42 are slidably arranged through the sliding grooves 41, allowing the mounting rails 27 to be adjusted to move closer to or farther from each other as needed.

[0039] Specifically, each protrusion 42 is threaded with a first threaded rod 43, which can rotate freely on the support plate 26. When the first threaded rod 43 rotates, due to the spiral nature of the thread, it can drive the protrusion 42 connected thereto to move along the sliding groove 41. If the first threaded rod 43 rotates clockwise, the protrusion 42 will move toward the center along the sliding groove 41, so that the two mounting rails 27 are close to each other; on the contrary, if the first threaded rod 43 rotates counterclockwise, the protrusion 42 will move to both sides along the sliding groove 41, so that the two mounting rails 27 are away from each other.

[0040] This design allows the operator to quickly adjust the distance between the mounting rails 27 according to the specific size of the trolley and the transportation requirements to ensure that the trolley can be firmly placed on the support plate 26. By rotating the first threaded rod 43, the operator can easily fine-tune the mounting rails 27 without additional tools or complicated steps, which greatly improves the adaptability and ease of operation of the transfer trolley.

[0041] like Figure 1 , Figure 2 and Figure 7 As shown, as a further technical solution, the support plate 26 is provided with a first through slot 51 along the sliding slot 41, the first through slot 51 has second through slots 52 on both sides, and a second threaded rod 53 is rotatably provided in the first through slot 51, and further includes a first slider 54 threadedly provided on the second threaded rod 53 and located in the first through slot 51; A third threaded rod 55 is rotatably disposed in the second through slot 52, and further includes a second slider 56 threadedly disposed on the third threaded rod 55 and located in the second through slot 52; Both the first slider 54 and the second slider 56 have abutment surfaces 57. After the trolley slides on the mounting rail 27, the trolley is used to abut the abutment surface 57 of the first slider 54 and push the first slider 54 to slide in the first through groove 51. After the first slider 54 slides, it is used to drive the second threaded rod 53 to rotate. It also includes a transmission component 58 for driving the third threaded rod 55 to rotate synchronously when the second threaded rod 53 rotates. After the third threaded rod 55 rotates, it is used to drive the second slider 56 to slide in the second through groove 52, and the sliding directions of the first slider 54 and the second slider 56 are opposite.

[0042] In this embodiment, we further refine the design of the support plate 26 to achieve more precise adjustment and control. The support plate 26 is provided with a first through slot 51 along the sliding slot 41, and a second through slot 52 is provided on both sides of the through slot. In the first through slot 51, we install a rotatable second threaded rod 53, on which a first slider 54 located in the first through slot 51 is threaded. Similarly, in the second through slot 52, we install a rotatable third threaded rod 55, on which a second slider 56 located in the second through slot 52 is threaded.

[0043] Both sliders are designed with abutment surfaces 57. When the trolley slides on the mounting rail 27, the trolley will abut against the abutment surface 57 of the first slider 54, thereby pushing the first slider 54 to move in the sliding direction in the first through slot 51. The movement of the first slider 54 will drive the second threaded rod 53 to rotate. Due to the action of the transmission assembly 58, the rotation of the second threaded rod 53 will synchronously drive the third threaded rod 55 to rotate. This synchronous rotation mechanism ensures the coordinated action of the two threaded rods, thereby causing the second slider 56 to slide in the second through slot 52 in the opposite direction.

[0044] The design of the transmission assembly 58 is very important, and it includes a first gear 581 disposed on both the second threaded rod 53 and the third threaded rod 55, and two transmission rods 582 rotatably disposed on the support plate 26, and second gears 583 are disposed at both ends of these transmission rods 582. The sides of the two transmission rods 582 that are close to each other are meshed with the first gear 581 on the second threaded rod 53, and the two second gears 583 that are far away from each other are respectively meshed with the first gear 581 on the third threaded rod 55. Such a design enables the second threaded rod 53 and the third threaded rod 55 to rotate synchronously, so that the first slider 54 and the second slider 56 can slide in opposite directions.

[0045] This design allows the trolley to slide on the mounting rail 27 through the relative sliding of the first slider 54 and the second slider 56, so that the trolley can push the first slider 54 to slide to a certain extent until the second slider 56 also abuts the trolley, thereby achieving limit braking of the trolley.

[0046] like Figure 6 As shown, as a further technical solution, the transmission assembly 58 includes: The second threaded rod 53 and the third threaded rod 55 are both provided with a first gear 581, and two transmission rods 582 are rotatably provided on the support plate 26, and second gears 583 are provided at both ends of the two transmission rods 582. The sides of the two transmission rods 582 close to each other are meshed with the first gear 581 on the second threaded rod 53, and the two second gears 583 of the two transmission rods 582 away from each other are respectively meshed with the first gear 581 on the third threaded rod 55.

[0047] In this embodiment, we describe in detail the configuration of a transmission assembly 58, which is used to synchronously control the rotation of the second threaded rod 53 and the third threaded rod 55 to achieve coordinated movement of the first slider 54 and the second slider 56. This innovative design enhances the adaptability of the support plate 26 and the accuracy of operation.

[0048] Specifically, the core of the transmission assembly 58 includes two transmission rods 582 disposed on the support plate 26, and a second gear 583 is disposed at both ends of each transmission rod 582. The two transmission rods 582 are disposed in parallel and can rotate freely on the support plate 26. The second threaded rod 53 and the third threaded rod 55 are both mounted with a first gear 581, which meshes with the second gear 583 on the transmission rod 582.

[0049] When the trolley slides on the mounting rail 27 and pushes the first slider 54, the movement of the first slider 54 causes the second threaded rod 53 to rotate. The first gear 581 on the second threaded rod 53 rotates accordingly, and transmits power to the transmission rod 582 through the meshing second gear 583. One end of the transmission rod 582 meshes with the first gear 581 on the second threaded rod 53, and the other end meshes with the first gear 581 on the third threaded rod 55. Therefore, when the second threaded rod 53 rotates, the second gear 583 at the other end of the transmission rod 582 also rotates accordingly, thereby driving the third threaded rod 55 to rotate.

[0050] This design ensures the synchronous rotation of the second threaded rod 53 and the third threaded rod 55, so that the first slider 54 and the second slider 56 can move in opposite directions to achieve the limiting effect on the opponent's car.

[0051] like Figure 1 and Figure 2 As shown, as a further technical solution, drawers 60 are slidably arranged on both sides of the bottom plate 10 .

[0052] As a further technical solution, a plurality of detachable sliding wheels 70 are rotatably provided on the bottom plate 10 .

[0053] As a further technical solution, the supporting plate 26 has a push handle 80 for pushing the supporting plate 26 .

[0054] In this embodiment, sliding drawers 60 are designed on both sides of the bottom plate 10, and these drawers 60 can be easily pulled out and pushed back from the bottom plate 10. These drawers 60 are used to store tools, spare parts or other necessary items, so that the required items can be quickly accessed during the transportation and maintenance of the handcart. The sliding track design of the drawer 60 ensures smooth and quiet operation. At the same time, the edge of the drawer 60 is designed with a magnetic sealing strip to prevent dust and moisture from entering the drawer 60 and protect the stored items.

[0055] In order to improve the mobility of the transfer cart, we set a number of detachable sliding wheels 70 on the base plate 10. These sliding wheels 70 are evenly distributed under the base plate 10, providing stable support and smooth mobility. Each sliding wheel 70 is fixed to the base plate 10 through a quick release mechanism, so that the operator can quickly remove or install the wheel to adapt to different usage scenarios. For example, the sliding wheel 70 can be installed when used on smooth ground, and the wheel can be removed on rough ground or when the position of the cart needs to be fixed.

[0056] A handle 80 is designed on the support plate 26 for pushing the support plate 26 when the position of the trolley needs to be moved or adjusted. The position and shape of the handle 80 are designed with ergonomics in mind, ensuring that the operator feels comfortable and saves effort when pushing the support plate 26. The material of the handle 80 is non-slip and wear-resistant material to improve durability and safety. In addition, the handle 80 can also be folded or disassembled to reduce the hindrance to the operator when pushing is not required.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
