Description

Technical Field

[0001] This application relates to the field of mechanical handling equipment technology, and in particular to a transfer cart suitable for complete electrical cabinets. Background Technology

[0002] In the production, installation, and transportation of complete electrical cabinets, a transport cart is often required for movement. Existing transport carts for complete electrical cabinets typically include a chassis with casters, support rods, handrails, and a cabinet contact plate. The cabinet contact plate is fixed to the chassis, and the front of the chassis has a fulcrum. During use, at least two people are needed to lift the rear of the transport cart, using the front wheels as a fulcrum to tilt the cart, thereby using the fulcrum to lift the electrical cabinet. Another person then needs to maintain the cabinet's stability from the front. This operation requires multiple people working together, which is not only labor-intensive and physically demanding but also inefficient. Improper coordination can also pose safety hazards. Therefore, this paper proposes a transport cart suitable for complete electrical cabinets. Utility Model Content

[0003] Technical problems to be solved

The cabinet contact plate is inclinedly positioned on the upper part of the chassis. Universal wheels are installed at the four corners of the lower surface of the chassis. A handrail is fixedly connected to the rear side of the chassis. The bottom end of the cabinet contact plate is hinged to the front end of the chassis. A first U-shaped seat is fixedly connected to the rear end of the upper surface of the chassis. A jack structure is movably connected inside the first U-shaped seat. A second U-shaped seat is fixedly connected to the rear end of the lower surface of the cabinet contact plate. The upper end of the jack structure is movably connected inside the second U-shaped seat. The jack structure has a foot-pressurization structure, which is fixedly connected to the upper surface of the chassis and positioned on the same side as the handrail. A flexible hose is connected to the output end of the foot-pressurization structure, and the other end of the flexible hose is connected to the jack structure. Telescopic support rods are provided at both ends of the jack structure. The upper end of the telescopic support rod is hinged to the lower end of the cabinet contact plate, and the lower end of the telescopic support rod is hinged to the upper surface of the chassis.

[0006] By adopting the above technical solution, through the cooperation of the hinge structure between the cabinet contact plate and the front end of the chassis and the jack structure, the cabinet contact plate can rotate around the hinge point at the front end of the chassis. The jack structure drives it to stand up or return to its original position through extension and retraction, replacing the operation of "multiple people lifting the rear to tilt the trolley" in the existing technology; it enables a single person to lift and lower the electrical cabinet, eliminating the need for multiple people to cooperate, reducing manpower consumption, lowering labor intensity, and avoiding safety hazards caused by improper cooperation among multiple people; through the combination of the jack structure, foot pressure structure, and hose, the foot pressure structure transmits pressure to the jack structure through the hose, driving its extension and retraction, and operation... Operators can control the movement of the cabinet contact plate by pressing it with their feet; replacing the traditional manual lifting method, it is easier to operate, and the foot-pressurization structure is arranged on the same side as the handrail, which facilitates single-person coordinated operation and improves operating efficiency; through the setting of the first U-shaped seat, the second U-shaped seat and the telescopic support rod, the jack structure is flexibly connected to the chassis and cabinet contact plate through the first U-shaped seat and the second U-shaped seat. The telescopic support rod extends and retracts synchronously with the rotation of the cabinet contact plate, which helps to distribute the force, enhances the stability and flexibility of the structural connection, ensures smooth force transmission, avoids excessive force on a single component, extends the service life of the equipment, and improves the reliability of the trolley operation.

[0007] Preferably, the cabinet contact plate is rotatable about the hinge point with the front end of the chassis to achieve standing up and resetting.

[0008] By adopting the above technical solution, the cabinet contact plate can rotate around the hinge point with the front end of the chassis to achieve standing up and resetting. This feature allows the cabinet contact plate to change its state according to operational needs. When standing up, it is convenient for the tilting point to pass through the bottom of the electrical cabinet. When resetting and tilting, it is conducive to the stable bearing and transportation of the electrical cabinet. The operation is flexible and adaptable to the needs of different handling stages.

[0009] Preferably, the extension and retraction of the jack structure can drive the cabinet contact plate to rotate around its hinge point with the front end of the chassis, and the telescopic support rod extends and retracts with the rotation of the cabinet contact plate.

[0010] By adopting the above technical solution, the telescopic drive of the jack structure rotates the cabinet contact plate around the front hinge point of the chassis, and the telescopic support rod extends and retracts with its rotation. This linkage ensures the stability and smoothness of the cabinet contact plate's rotation process, while the telescopic support rod helps to share the force, reducing the load on the jack structure, extending the equipment's service life, and enhancing the overall reliability of the structure during operation.

[0011] Preferably, the foot pressure-applying structure includes a pedal for foot to step on.

[0012] By adopting the above technical solution, the foot-pressurized structure includes a pedal for foot to step on. The operator can control the jack structure by stepping on the pedal. The operation method is simple and labor-saving. Compared with the traditional manual lifting method, it reduces the difficulty of operation, makes single-person operation more convenient and efficient, and improves work efficiency.

[0013] Preferably, the bottom of the upper surface of the cabinet contact plate is provided with a raised point.

[0014] By adopting the above technical solution, a lifting point is provided at the bottom of the upper surface of the cabinet contact plate. When the cabinet contact plate is upright, the lifting point can pass through the bottom of the electrical cabinet to form a bottom support, preventing the electrical cabinet from slipping during transportation, ensuring the stable load-bearing of the electrical cabinet, and improving the safety of the transportation process.

[0015] Preferably, the upper surface of the cabinet contact plate is provided with a buffer and shock-absorbing layer, and the lower surface of the cabinet contact plate is provided with a wear-resistant layer.

[0016] By adopting the above technical solution, a buffer and shock-absorbing layer is set on the upper surface of the cabinet contact plate, and a wear-resistant layer is set on the lower surface. The buffer and shock-absorbing layer can buffer the electrical cabinet when it comes into contact with the cabinet contact plate, preventing the surface of the electrical cabinet from being scratched or damaged by vibration; the wear-resistant layer can reduce the friction between the cabinet contact plate and the jack structure and telescopic support rod, extending the service life of the cabinet contact plate.

[0017] Preferably, the cushioning and shock-absorbing layer is made of rubber or silicone material.

[0018] By adopting the above technical solution, the buffer and shock absorption layer is made of rubber or silicone material. Rubber and silicone have good elasticity and wear resistance, which can effectively enhance the buffer and shock absorption effect and better protect the surface of the appliance cabinet. At the same time, their material is soft and will not scratch the appliance cabinet, thus meeting the needs of appliance cabinet protection.

[0019] Preferably, the wear-resistant layer is made of metal sheet or wear-resistant resin material.

[0020] By adopting the above technical solution, the wear-resistant layer is made of metal sheet or wear-resistant resin material. Metal sheet and wear-resistant resin have high hardness and wear resistance, which can significantly reduce the wear of the lower surface of the cabinet contact plate when in contact with the jack structure and telescopic support rod and during relative movement, extend the service life of the cabinet contact plate, and ensure its structural stability for long-term use.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This is a trolley suitable for complete sets of electrical cabinets. Through the cooperation of a hinged structure between the cabinet contact plate and the front end of the chassis, and a jack structure, the cabinet contact plate can rotate around the hinge point at the front end of the chassis. The jack structure, through extension and retraction, drives the cabinet to stand up or return to its original position, replacing the existing technology that requires multiple people to lift the rear of the trolley to tilt it.

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0031] Example 1: A transport vehicle suitable for complete sets of electrical cabinets, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a chassis 1 and a cabinet contact plate 2. The cabinet contact plate 2 is inclinedly mounted on the upper part of the chassis 1. Universal wheels 3 are installed at the four corners of the lower surface of the chassis 1. A handrail 4 is fixedly connected to the rear side of the chassis 1. The bottom end of the cabinet contact plate 2 is hinged to the front end of the chassis 1. A first U-shaped seat 5 is fixedly connected to the rear end of the upper surface of the chassis 1. A jack structure 6 is movably connected inside the first U-shaped seat 5. A second U-shaped seat 7 is fixedly connected to the rear end of the lower surface of the cabinet contact plate 2. The upper end of the jack structure 6 is movably connected inside the second U-shaped seat 7. The jack structure 6 has a foot-pressurization structure 8. The foot-pressurizing structure 8 is fixedly connected to the upper surface of the chassis 1 and is located on the same side as the handrail 4. A flexible hose 9 is connected to the output end of the foot-pressurizing structure 8, and the other end of the hose 9 is connected to the jack structure 6. Telescopic support rods 10 are installed at both ends of the jack structure 6. The upper end of the telescopic support rod 10 is hinged to the lower end of the cabinet contact plate 2, and the lower end of the telescopic support rod 10 is hinged to the upper surface of the chassis 1. Through the hinge structure between the cabinet contact plate 2 and the front end of the chassis 1, and the cooperation of the jack structure 6, the cabinet contact plate 2 can rotate around the hinge point at the front end of the chassis 1. The jack structure 6... The extension and retraction drive raises or lowers the cabinet, replacing the previous method of "multiple people lifting the rear to tilt the trolley." This allows for single-person operation of raising and lowering the electrical cabinet, eliminating the need for multiple people, reducing manpower consumption, lowering labor intensity, and avoiding safety hazards caused by improper coordination. Through the combination of the jack structure 6, the foot-pressure structure 8, and the hose 9, the foot-pressure structure 8 transmits pressure to the jack structure 6 via the hose 9, driving its extension and retraction. The operator can control the movement of the cabinet contact plate 2 simply by pressing with their foot. This replaces the traditional manual lifting method, making operation more economical. The foot-pressurized structure 8 and the handrail 4 are arranged on the same side, which facilitates single-person coordinated operation and improves operating efficiency. Through the setting of the first U-shaped seat 5, the second U-shaped seat 7 and the telescopic support rod 10, the jack structure 6 is flexibly connected to the chassis 1 and the cabinet contact plate 2 through the first U-shaped seat 5 and the second U-shaped seat 7. The telescopic support rod 10 extends and retracts synchronously with the rotation of the cabinet contact plate 2, which helps to share the force, enhances the stability and flexibility of the structural connection, ensures smooth force transmission, avoids excessive force on a single component, extends the service life of the equipment, and improves the reliability of the operation of the trolley.

[0032] Reference Figure 1 , Figure 2 and Figure 4The cabinet contact plate 2 can rotate around its hinge point with the front end of the chassis 1 to achieve uprighting and resetting. The extension and retraction of the jack structure 6 drives the cabinet contact plate 2 to rotate around its hinge point with the front end of the chassis 1. The telescopic support rod 10 extends and retracts with the rotation of the cabinet contact plate 2. This feature allows the cabinet contact plate 2 to change its state according to operational needs. When upright, it facilitates the insertion of the tilting point 11 through the bottom of the electrical cabinet; when resetting and tilting, it facilitates stable load-bearing and transportation of the electrical cabinet. The operation is flexible and adaptable to the needs of different handling stages. The extension and retraction of the jack structure 6 drives the cabinet contact plate 2 to rotate around its hinge point with the front end of the chassis 1, and the telescopic support rod 10 extends and retracts with its rotation. This linkage ensures the stability and smoothness of the cabinet contact plate 2's rotation process. The telescopic support rod 10 helps to share the force, reducing the load on the jack structure 6, extending the equipment's service life, and enhancing the overall structural reliability during operation.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The foot-pressurizing structure 8 includes a foot pedal. The bottom of the upper surface of the cabinet contact plate 2 is provided with a lifting point 11. The foot-pressurizing structure 8 includes a foot pedal. The operator can control the jack structure 6 by stepping on the pedal. The operation method is simple and labor-saving. Compared with the traditional manual lifting method, it reduces the difficulty of operation, makes single-person operation more convenient and efficient, and improves work efficiency. The bottom of the upper surface of the cabinet contact plate 2 is provided with a lifting point 11. When the cabinet contact plate 2 is upright, the lifting point 11 can pass through the bottom of the electrical cabinet to form a bottom support, preventing the electrical cabinet from slipping during transportation, ensuring the stable load-bearing of the electrical cabinet, and improving the safety of the transportation process.

[0034] Reference Figure 1 , Figure 2 and Figure 5The upper surface of the cabinet contact plate 2 is provided with a buffer and shock-absorbing layer 12, and the lower surface of the cabinet contact plate 2 is provided with a wear-resistant layer 13. The buffer and shock-absorbing layer 12 is made of rubber or silicone material, and the wear-resistant layer 13 is made of metal sheet or wear-resistant resin material. The upper surface of the cabinet contact plate 2 is provided with a buffer and shock-absorbing layer 12, and the lower surface is provided with a wear-resistant layer 13. The buffer and shock-absorbing layer 12 acts as a buffer when the electrical cabinet comes into contact with the cabinet contact plate 2, preventing the surface of the electrical cabinet from being scratched or damaged by vibration. The wear-resistant layer 13 reduces the friction between the cabinet contact plate 2 and the jack structure 6 and the telescopic support rod 10, extending the service life of the cabinet contact plate 2. The buffer and shock-absorbing layer 12 is made of rubber or silicone. Rubber and silicone have good elasticity and wear resistance, which can effectively enhance the buffer and shock absorption effect and better protect the surface of the electrical cabinet. At the same time, its soft material will not scratch the electrical cabinet, which meets the needs of electrical cabinet protection. The wear-resistant layer 13 is made of metal sheet or wear-resistant resin. Metal sheet and wear-resistant resin have high hardness and wear resistance, which can significantly reduce the wear of the lower surface of the cabinet contact plate 2 when it comes into contact with the jack structure 6 and the telescopic support rod 10 and during relative movement, extending the service life of the cabinet contact plate 2 and ensuring its structural stability for long-term use.

[0035] In this embodiment, through the cooperation of the hinge structure between the cabinet contact plate 2 and the front end of the chassis 1 and the jack structure 6, the cabinet contact plate 2 can rotate around the hinge point at the front end of the chassis 1. The jack structure 6 drives it to stand up or reset by extension and retraction, replacing the operation of "multiple people lifting the rear to tilt the trolley" in the prior art; it enables a single person to complete the lifting and lowering of the electrical cabinet, without the need for multiple people to cooperate, reducing manpower consumption, reducing labor intensity, and avoiding the safety hazards of improper cooperation by multiple people; through the combination of the jack structure 6, the foot pressure structure 8 and the hose 9, the foot pressure structure 8 transmits pressure to the jack structure 6 through the hose 9, driving its extension and retraction, allowing the operator to... The movement of the cabinet contact plate 2 can be controlled by foot pressure; replacing the traditional manual lifting method, the operation is more labor-saving, and the foot pressure structure 8 is arranged on the same side as the handrail 4, which facilitates single-person coordinated operation and improves operating efficiency; through the setting of the first U-shaped seat 5, the second U-shaped seat 7 and the telescopic support rod 10; the jack structure 6 is flexibly connected to the chassis 1 and the cabinet contact plate 2 through the first U-shaped seat 5 and the second U-shaped seat 7. The telescopic support rod 10 extends and retracts synchronously with the rotation of the cabinet contact plate 2, which helps to share the force, enhances the stability and flexibility of the structural connection, ensures smooth force transmission, avoids excessive force on a single component, extends the service life of the equipment, and improves the reliability of the operation of the trolley.

[0036] The implementation principle of this application embodiment is as follows: In the initial state, the cabinet contact plate 2 is in an inclined state, and the telescopic support rod 10 is adapted to its inclination angle to prepare for subsequent operations; when it is necessary to move the electrical cabinet, the operator first holds the handrail 4 on the back of the chassis 1 to maintain the balance of the vehicle, and then steps on the foot pressure structure 8, and the pressure generated is transmitted to the jack structure 6 through the hose 9. Since the lower end of the jack structure 6 is movably connected to the chassis 1 via the first U-shaped seat 5, and the upper end is movably connected to the cabinet contact plate 2 via the second U-shaped seat 7, the jack structure 6 will extend under pressure, thereby driving the cabinet contact plate 2 to rotate around the hinge point at the front end of the chassis 1, so that the cabinet contact plate 2 stands up; then, the lifting point 11 at the bottom of the upper surface of the cabinet contact plate 2 is inserted into the bottom of the electrical cabinet. At this time, the lifting point 11 forms a bottom support for the bottom of the electrical cabinet. At the same time, the telescopic support rod 10 extends synchronously with the standing of the cabinet contact plate 2, which plays a role in stabilizing the structure; after that, the operator continues to step on the foot pressure structure 8, which shortens the jack structure 6. Under its own weight and the driving force of the jack structure 6, the cabinet contact plate 2 rotates in the opposite direction around the front hinge point and returns to the tilted state. During this process, the lifting point 11 tilts the electrical cabinet as the cabinet contact plate 2 tilts. The electrical cabinet, relying on its own weight, rests against the buffer and shock-absorbing layer 12 of the cabinet contact plate 2, achieving stable load-bearing. Simultaneously, the telescopic support rod 10 shortens to match the tilt angle of the cabinet contact plate 2. The operator holds the handle 4 and pushes the trolley using the casters 3 on the lower surface of the chassis 1, moving the electrical cabinet to the appropriate position. Upon reaching the target position, the operator again steps on the foot-pressurizing structure 8, driving the jack structure 6 to extend, causing the cabinet contact plate 2 to stand upright again around the front hinge point. Then, the lifting point 11 is pulled out from the bottom of the electrical cabinet, and the cabinet is placed stably on the ground, completing the entire handling process. Throughout the operation, the wear-resistant layer 13 on the lower surface of the cabinet contact plate 2 reduces friction between it and the jack structure 6 and the telescopic support rod 10, helping to extend the service life of the device.
