Description

Technical Field

[0001] This invention relates to the field of switchgear trolley transfer technology, specifically to a 10kV trolley switchgear transfer device. Background Technology

[0002] In substation maintenance, it is necessary to move 10kV trolleys from their working positions to outside the switchgear. Different substations have different switchgear models, so different types of 10kV trolley switch transfer devices are required, which is costly.

[0003] Substation maintenance may require moving multiple 10kV trolleys from their switchgear locations, necessitating the use of multiple 10kV trolley transfer units. This not only occupies significant space in the switchgear room but also incurs high costs. If there are insufficient transfer units on-site, multiple people are needed to lift the 10kV trolleys from the transfer units before moving them to another 10kV trolley, resulting in substantial manpower and time consumption. Summary of the Invention

[0004] This invention proposes a 10kV handcart switch transfer device, which solves the problem that the height of the existing handcart transfer trolley cannot be adjusted or is inconvenient to adjust, thus requiring the manufacture of a specific transfer trolley for each individual switch cabinet.

[0005] The technical solution of the present invention is as follows:

[0018] As a further technical solution, the drive assembly also includes a first foot pedal hinged at the center of the base plate and a second foot pedal hinged at the center of the base plate. The first foot pedal has a first foot pedal end and a first hinge end, which are located at opposite ends of the first foot pedal. The first hinge end is used to hinge with the first piston rod. After the first foot pedal swings along the center of the base plate, it is used to drive the second piston rod to move within the second telescopic cavity.

[0030] The working principle and beneficial effects of this invention are as follows:

[0031] In this invention, to address the problem of inflexible or inconvenient height adjustment of existing handcart transfer trolleys, a 10kV handcart switch transfer device is provided. This trolley achieves height adjustability through a series of ingenious structural designs, thus adapting to the handcart transfer needs of different switchgear cabinets without requiring the manufacture of a specific transfer trolley for each individual switchgear cabinet. Specifically, the transfer trolley in this embodiment includes a base plate with mounting plates on both sides. Each mounting plate has a first sliding groove on one side. A first sliding rod is slidably disposed within the first sliding groove, while a first hinge rod is hinged to the other side of the mounting plate.

This height-adjustable design gives the transfer trolley greater versatility and flexibility, making it suitable for various switchgear handcarts of different models and sizes. This solves the problem of requiring a separate transfer trolley for each switchgear in existing technologies, greatly improving the practicality and economy of the transfer trolley.

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] Example

[0051] like Figure 1 and picture Figure 3 As shown, a 10kV handcart switch transfer device is characterized in that it includes a base plate 10 set on the ground and mounting plates 21 set on both sides of the base plate 10, wherein one side of the mounting plate 21 has a first sliding groove 22.

[0052] A first slide rod 23 is slidably disposed within the first slide groove 22. A first hinge rod 24 is hingedly disposed on the side of the mounting plate 21 away from the first slide groove 22. Second hinge rods 25 are hingedly disposed at both ends of the first slide rod 23. The center of the first hinge rod 24 and the center of the second hinge rod 25 are hinged together. After the first slide rod 23 slides within the first slide groove 22, it drives the second hinge rod 25 to slide synchronously with the first slide rod 23. The second hinge rod 25 and the first hinge rod 24 rotate relative to each other around their centers.

[0053] It also includes a drive assembly 30 for pushing the second hinge rod 25 to slide within the first groove 22;

[0054] It also includes a support plate 26 hinged to one end of the second hinge rod 25 away from the base plate 10. The base plate 10 has a second slide groove 22. It also includes a second slide rod slidably disposed in the second slide groove 22. One end of the first hinge rod 24 away from the base plate 10 is hinged to the second slide rod. The support plate 26 is used to support the handcart.

[0055] The support plate 26 has two mounting rails 27, and the handcart is slidably mounted on the mounting rails 27. In this invention, there can be a plurality of first hinge rods 24 and second hinge rods 25, and the plurality of first hinge rods 24 and second hinge rods 25 are connected end to end.

[0056] As a specific implementation method, to solve the problem of the inability or inconvenience of adjusting the height of the handcart transfer trolley in the prior art, this embodiment provides a 10kV handcart switch transfer device. This trolley achieves height adjustability through a series of ingenious structural designs, thereby adapting to the handcart transfer needs of different switchgear cabinets, eliminating the need to manufacture a specific transfer trolley for each individual switchgear cabinet. Specifically, the transfer trolley in this embodiment includes a base plate 10, with mounting plates 21 on both sides of the base plate 10. Each mounting plate 21 has a first sliding groove 22 on one side. A first sliding rod 23 is slidably disposed within the first sliding groove 22, while a first hinge rod 24 is hinged to the other side of the mounting plate 21. Second hinge rods 25 are hinged to both ends of the first sliding rod 23, and the center of the first hinge rod 24 is hinged to the center of the second hinge rod 25. This design allows the first sliding rod 23 to slide synchronously with the second hinge rod 25 when it slides within the first sliding groove 22. Furthermore, the second hinge rod 25 can rotate relative to the first hinge rod 24 around its center, providing height adjustment capability for the transfer trolley. The addition of the drive assembly 30 further enhances the functionality of the transfer trolley, enabling it to push the second hinge rod 25 to slide within the first sliding groove 22, thereby achieving height adjustment of the support plate 26. The support plate 26 is hinged to the end of the second hinge rod 25 furthest from the base plate 10. The base plate 10 has a second sliding groove 22, within which a second sliding rod is slidably mounted. The end of the first hinge rod 24 furthest from the base plate 10 is hinged to the second sliding rod. The support plate 26 supports the handcart and has two mounting rails 27 on it, allowing the handcart to slide smoothly on these rails. Through this design, the transfer trolley can not only adapt to handcarts of different heights but also provide stable support during transport, preventing the handcart from tipping over. This highly adjustable design makes the transfer trolley more versatile and flexible, and can be used for various switchgear trolleys of different models and sizes. This solves the problem of having to manufacture a separate transfer trolley for each switchgear in the existing technology, and greatly improves the practicality and economy of the transfer trolley.

[0057] like Figure 4 As shown, as a further technical solution, the driving component 30 includes:

[0058] A first piston rod 31 is provided on the base plate 10. The telescopic end of the first piston rod 31 is provided on the first slide rod 23. The first piston rod 31 has a first telescopic cavity 311. It also includes an oil storage cavity 32 provided on the base plate 10. The oil storage cavity 32 has an oil outlet 321. A one-way valve 33 is provided at the oil outlet 321. The oil storage cavity 32 communicates with the first telescopic cavity 311 through the oil outlet 321. It also includes a second piston rod 34 provided on the base plate 10. The second piston rod 34 has a second telescopic cavity 341. The oil storage cavity 32 communicates with the second telescopic cavity 341 through the oil outlet 321.

[0059] When the first piston rod 31 moves away from the oil storage cavity 32, the one-way valve 33 is in the open / closed state; when the first piston rod 31 moves closer to the oil storage cavity 32, the one-way valve 33 is in the closed state.

[0060] The oil storage cavity 32 also has a pressure relief port 322, which is connected to the first telescopic cavity 311. It also includes an adjusting member 35 disposed between the oil storage cavity 32 and the first telescopic cavity 311, which is used to open or close the pressure relief port 322.

[0061] In this embodiment, we further optimized the drive assembly 30 of the 10KV handcart anti-tipping transfer trolley to improve its operational flexibility and safety. The core of the drive assembly 30 includes two piston rods and a precision-designed hydraulic system.

[0062] Specifically, a first piston rod 31 is mounted on the base plate 10, and its telescopic end is connected to the first slide rod 23, forming the main part of the drive assembly 30. The first piston rod 31 has a first telescopic cavity 311 inside for storing hydraulic oil. Correspondingly, the base plate 10 also has an oil storage cavity 32, serving as a reservoir for hydraulic oil. The oil storage cavity 32 has 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, preventing backflow.

[0063] When the first piston rod 31 extends outward, moving away from the oil reservoir 32, the one-way valve 33 opens, allowing hydraulic oil to flow from the oil reservoir 32 into the first telescopic cavity 311. This pushes the piston rod to extend, thereby causing the first slide rod 23 and the second hinge rod 25 to slide within the slide groove 22, achieving height adjustment of the support plate 26. Conversely, when the first piston rod 31 retracts inward, moving closer to the oil reservoir 32, the one-way valve 33 closes, preventing oil backflow and ensuring that the pressure within the first telescopic cavity 311 is maintained.

[0064] To further control the pressure of the hydraulic system, the oil reservoir 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 pressure when the system pressure is too high, preventing system damage. An adjusting component 35 is installed between the oil reservoir 32 and the first telescopic cavity 311. This adjusting component 35 can open or close the pressure relief port 322 as needed. In this way, the operator can precisely control the pressure of the hydraulic system according to actual usage conditions, ensuring the stability and safety of the transfer trolley under different loads and operating conditions.

[0065] Through this design, our drive assembly 30 not only provides precise height adjustment capability, but also enhances the safety performance of the system, enabling the 10KV handcart anti-tipping transfer trolley to work reliably under various operating conditions.

[0066] like Figure 6 As shown, as a further technical solution, the adjusting member 35 includes:

[0067] A third piston rod 36 is provided on the base plate 10, and an abutment ball 37 is provided on the third piston rod 36;

[0068] The pressure relief port 322 has an abutting inclined surface 3221. 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.

[0069] In this embodiment, we have innovatively designed the adjusting member 35 to achieve precise control of the pressure relief port 322. The core of the adjusting member 35 is a third piston rod 36, which is mounted on the base plate 10 and has an abutment ball 37 installed on it. 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.

[0070] The specific operation is as follows: The pressure relief port 322 is designed with an abutting inclined surface 3221. When the third piston rod 36 extends outward, the abutting ball 37 moves accordingly and contacts the abutting inclined surface 3221, thus closing the pressure relief port 322 and preventing hydraulic oil from flowing out of the first telescopic cavity 311, maintaining system pressure. Conversely, when the third piston rod 36 retracts inward, the abutting ball 37 leaves the abutting inclined surface 3221, and the pressure relief port 322 opens accordingly, allowing hydraulic oil to flow out of the first telescopic cavity 311, thereby releasing system pressure.

[0071] 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 status and load of the trolley transfer vehicle to ensure the stability and safety of the system.

[0072] As a further technical solution, the drive assembly 30 also includes a first foot pedal 38 hinged at the center of the base plate 10 and a second foot pedal 39 hinged at the center of the base plate 10. The first foot pedal 38 has a first foot pedal end 381 and a first hinge end 382, ​​which are respectively located at both ends of the first foot pedal 38. The first hinge end 382 is used to be hinged to the first piston rod 31. After the first foot pedal 38 swings along the center of the base plate 10, it is used to drive the second piston rod 34 to move within the second telescopic cavity 341.

[0073] The second foot pedal 39 has a second foot pedal end 391 and a second hinge end 392. The second foot pedal end 391 and the second hinge end 392 are respectively located at both ends of the second foot pedal 39. The second hinge end 392 is used to hinge with the second piston rod 34. After the second foot pedal 39 swings along the center on the base plate 10, it is used to drive the third piston rod 36 to move. In addition, this solution provides elastic elements at the first piston rod 31 and the second piston rod 34 to provide the force for the first foot pedal 38 and the second foot pedal 39 to return.

[0074] In this embodiment, to improve the maneuverability and convenience of the 10KV handcart anti-tipping transfer trolley, we further optimized the drive assembly 30 and introduced a foot pedal mechanism. Specifically, we hinged two foot pedals at the center of the base plate 10: a first foot pedal 38 and a second foot pedal 39.

[0075] The first foot pedal 38 is designed with a first foot pedal end 381 and a first hinge end 382, ​​which are located at opposite ends of the foot pedal. The first hinge end 382 is hinged to the first piston rod 31, so that when the operator presses down on the first foot pedal 38, the foot pedal swings around its center point on the base plate 10. This action drives the first piston rod 31, which in turn pushes the second piston rod 34 to move within the second telescopic cavity 341. This design allows the operator to control the pressure of the hydraulic system through simple foot pedal movements, thereby adjusting the height of the support plate 26.

[0076] The second foot pedal 39 also has a second foot pedal end 391 and a second hinge end 392, which are located at opposite ends of the foot pedal. The second hinge end 392 is hinged to the second piston rod 34. When the operator presses 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. Its movement can control whether the abutment ball 37 contacts the abutment slope 3221 of the pressure relief port 322, thereby regulating the pressure release of the hydraulic system.

[0077] This foot pedal design provides a direct and effortless way to control the hydraulic system of the transfer trolley, allowing operators to easily adjust the height of the support plate 26 and the pressure of the hydraulic system without the need for additional tools or complex operations. This design not only improves operational efficiency but also reduces labor intensity during 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 transfers while simultaneously improving work efficiency.

[0078] like Figure 2 As shown, as a further technical solution, the support plate 26 has a sliding groove 41, and both mounting rails 27 have protrusions 42. The protrusions 42 are slidably disposed in the sliding groove 41. After the protrusions 42 slide in the sliding groove 41, the two mounting rails 27 move closer to each other or further away from each other.

[0079] The protrusion 42 is threaded with a first threaded rod 43, and the first threaded rod 43 is rotatably mounted on the support plate 26. After the first threaded rod 43 rotates on the support plate 26, it is used to drive the two protrusions 42 to move closer to each other or further away from each other.

[0080] In this embodiment, we have innovated the design of the support plate 26 to enable dynamic adjustment of the mounting rails 27, allowing them to adapt to handcarts of different sizes. A sliding groove 41 is specially designed on the support plate 26, while both mounting rails 27 are provided with protrusions 42. These protrusions 42 are slidably set through the sliding groove 41, allowing the mounting rails 27 to be adjusted to move closer or further apart as needed.

[0081] 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 helical nature of the thread, it can drive the protrusion 42 connected to it to move along the sliding groove 41. If the first threaded rod 43 rotates clockwise, the protrusion 42 will move closer to the center along the sliding groove 41, causing the two mounting rails 27 to move closer together; conversely, if the first threaded rod 43 rotates counterclockwise, the protrusion 42 will move to both sides along the sliding groove 41, causing the two mounting rails 27 to move away from each other.

[0082] 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 transfer requirements, ensuring that the trolley can be stably placed on the support plate 26. By rotating the first threaded rod 43, the operator can easily make fine adjustments to the mounting rails 27 without additional tools or complicated steps, greatly improving the adaptability and ease of operation of the transfer trolley.

[0083] 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 groove 51 along the sliding groove 41, the first through groove 51 has second through grooves 52 on both sides, and a second threaded rod 53 is rotatably provided in the first through groove 51, and also includes a first slider 54 threaded on the second threaded rod 53 and located in the first through groove 51.

[0084] A third threaded rod 55 is rotatably disposed in the second through groove 52, and a second slider 56 is threaded on the third threaded rod 55 and located in the second through groove 52;

[0085] Both the first slider 54 and the second slider 56 have abutment surfaces 57. After the handcart slides on the mounting rail 27, the handcart abuts against the abutment surface 57 of the first slider 54 and pushes the first slider 54 to slide in the first through groove 51. After the first slider 54 slides, it drives the second threaded rod 53 to rotate. It also includes a transmission assembly 58 that drives the third threaded rod 55 to rotate synchronously when the second threaded rod 53 rotates. After the third threaded rod 55 rotates, it drives the second slider 56 to slide in the second through groove 52. The sliding directions of the first slider 54 and the second slider 56 are opposite.

[0086] In this embodiment, we further refined the design of the support plate 26 to achieve more precise adjustment and control. The support plate 26 has a first through groove 51 along the sliding groove 41, and second through grooves 52 are respectively provided on both sides of this through groove. Within the first through groove 51, we installed a rotatable second threaded rod 53, on which a first slider 54 located within the first through groove 51 is threaded. Similarly, within the second through grooves 52, we installed a rotatable third threaded rod 55, on which a second slider 56 located within the second through groove 52 is threaded.

[0087] Both sliders are designed with abutment surfaces 57. When the handcart slides on the mounting rail 27, it abuts against the abutment surface 57 of the first slider 54, thereby pushing the first slider 54 to move in the sliding direction within the first through groove 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 allowing the second slider 56 to slide in the opposite direction within the second through groove 52.

[0088] The design of the transmission assembly 58 is crucial. It includes first gears 581 mounted on both the second threaded rod 53 and the third threaded rod 55, and two transmission rods rotatably mounted on the support plate 26. Each end of these transmission rods 582 is equipped with a second gear 583. The two transmission rods 582 with their sides closer together mesh with the first gear 581 on the second threaded rod 53, while the two second gears 583 with their sides further apart mesh with the first gear 581 on the third threaded rod 55. This design allows the second threaded rod 53 and the third threaded rod 55 to rotate synchronously, enabling the first slider 54 and the second slider 56 to slide in opposite directions.

[0089] This design allows the handcart to slide on the mounting rail 27, and through the relative sliding of the first slider 54 and the second slider 56, the handcart can push the first slider 54 to slide to a certain extent until the second slider 56 also comes into contact with the handcart, thereby achieving the limit braking of the handcart.

[0090] like Figure 6 As shown, as a further technical solution, the transmission assembly 58 includes:

[0091] Both the second threaded rod 53 and the third threaded rod 55 are provided with a first gear 581. Two transmission rods 582 are rotatably arranged on the support plate 26, and both ends of the two transmission rods 582 are provided with a second gear 583. The two transmission rods 582 that are close to each other mesh with the first gear 581 on the second threaded rod 53, and the two second gears 583 that are far apart from each other mesh with the first gear 581 on the third threaded rod 55.

[0092] In this embodiment, we describe in detail the configuration of a transmission assembly 58 for synchronously controlling 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 and operational precision of the support plate 26.

[0093] Specifically, the core of the transmission assembly 58 includes two transmission rods 582 mounted on the support plate 26, each with a second gear 583 at both ends. These two transmission rods 582 are arranged in parallel and can rotate freely on the support plate 26. First gears 581 are mounted on both the second threaded rod 53 and the third threaded rod 55, and these gears mesh with the second gears 583 on the transmission rods 582.

[0094] When the handcart 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, transmitting 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, thereby driving the third threaded rod 55 to rotate.

[0095] This design ensures the synchronous rotation of the second threaded rod 53 and the third threaded rod 55, allowing the first slider 54 and the second slider 56 to move in opposite directions, thereby achieving the limiting effect on the handcart.

[0096] like Figure 1 and Figure 2 As shown, as a further technical solution, drawers 60 are slidably provided on both sides of the base plate 10.

[0097] As a further technical solution, the base plate 10 is rotatably provided with several detachable sliding wheels 70.

[0098] As a further technical solution, the support plate 26 has a pusher 80 for pushing the support plate 26.

[0099] In this embodiment, sliding drawers 60 are designed on both sides of the base plate 10. These drawers 60 can be easily pulled out and pushed back from the base plate 10. These drawers 60 are used to store tools, spare parts, or other necessary items, allowing for quick access to the required items during trolley transport and maintenance. The sliding track design of the drawers 60 ensures smooth and quiet operation. Meanwhile, the edges of the drawers 60 are designed with magnetic sealing strips to prevent dust and moisture from entering the interior of the drawers 60, protecting the stored items.

[0100] To improve the mobility of the transfer trolley, several detachable casters 70 are installed on the base plate 10. These casters 70 are evenly distributed under the base plate 10, providing stable support and a smooth movement experience. Each caster 70 is fixed to the base plate 10 by a quick-release mechanism, allowing the operator to quickly remove or install the wheels to adapt to different usage scenarios. For example, the casters 70 can be installed when using on a smooth surface, while they can be removed when using on a rough surface or when the trolley needs to be fixed in place.

[0101] A push handle 80 is designed on the support plate 26 for pushing the support plate 26 when the handcart position needs to be moved or adjusted. The position and shape of the push handle 80 are ergonomically designed to ensure that the operator feels comfortable and effortless when pushing the support plate 26. The push handle 80 is made of non-slip and wear-resistant material to improve durability and safety. In addition, the push handle 80 can be folded or disassembled to reduce obstruction to the operator when pushing is not needed.

[0102] The above are merely 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 within the protection scope of the present invention.
