Technical Field
[0001] This utility model relates to the field of switch cabinet technology, specifically a multi-functional service handcart. Background Technology
[0002] As an important piece of equipment in the power system, switchgear undertakes the key tasks of power distribution, control and protection. Generally, service trolleys are used in the process of moving, installing and replacing electronic components of switchgear. In order to ensure the operating efficiency and safety of switchgear, the design and technical level of service trolleys are particularly important.
[0003] For example, utility model patent number 202321176246.5 discloses a service trolley for switchgear, comprising: a chassis, a scissor lift assembly, a tray, and two brackets. The chassis has guide wheels at its bottom. The scissor lift assembly includes at least a first scissor lift arm and a second scissor lift arm hinged together. The bottom of the first scissor lift arm is hinged to one end of the chassis, and the bottom of the second scissor lift arm is connected to a first drive mechanism. The first drive mechanism is adapted to drive the bottom of the second scissor lift arm to move closer to or further away from the bottom of the first scissor lift arm. The tray is positioned on top of the scissor lift assembly, and the two brackets are positioned on both sides of the tray via a second drive mechanism. The second drive mechanism is adapted to drive the two brackets to move closer to or further away from each other. This service trolley can accommodate switchgear of different heights and circuit breakers of different widths, achieving multi-purpose use. It eliminates the need for multiple service trolleys of different sizes in the substation, reducing space occupation within the substation and lowering maintenance costs, thus improving the substation's economic efficiency.
[0004] Although existing service trolleys can accommodate switch cabinets of different heights and circuit breakers of different widths, they cannot place and move two or more sets of switch cabinets and circuit breakers at once. Furthermore, they require more manual operation during the adjustment process, making them inconvenient to operate and not very practical. To address these issues, the inventors proposed a multi-functional service handcart. Utility Model Content
[0005] To address the problem that existing service trolleys cannot place and transport two or more sets of switch cabinets and circuit breakers at once, and require more manual operation during adjustment, making them inconvenient to use, the purpose of this utility model is to provide a multi-functional service handcart.

[0008] Preferably, the connecting frames are symmetrically distributed, and sliders are respectively installed on the connecting rods of the two sets of connecting frames. A rotating plate is installed on the outside of the slider through a damping rotating shaft, and two rotating plates are provided in each set. A clamping frame is installed on the inner side of the rotating plate through a damping rotating shaft. The surface of the clamping frame is provided with an anti-slip pad, and clamping plates are provided on both sides of the anti-slip pad. A rubber washer is provided on the inner wall of the circular hole of the clamping plate. A soft pad is provided inside the slider for anti-slip. The rotating plate can be rotated arbitrarily by force to adjust the position of the clamping frame. The position can be adjusted by holding the anti-slip pad. The switch cabinet and circuit breaker are clamped by cooperating with the baffle.

One side of the upper surface of the placement plate 10 is fixedly connected to a rail 1 13. The other side of the upper surface of the placement plate 10 is provided with a rail 2 14 that is symmetrically distributed with rail 1 13.

The upper side of the handrail frame 11 is provided with a placement rod 12.
[0022] The surface of the placement plate 10 is provided with evenly distributed through holes, a baffle 1002 is fixedly installed on the upper surface of the placement plate 10, and a handle 1001 is fixedly connected to the end face of the placement plate 10.
[0023] By adopting the above technical solution, the placement plate 10 can be pulled out by the handle 1001, making it convenient to take out the switch cabinet and circuit breaker on the placement plate 10.
[0024] A driven gear 603 is provided on the side of the driving gear 602. The driving gear 602 and the driven gear 603 mesh with each other. A screw 604 is fixedly installed on the upper end of the driven gear 603. A guide rod is provided on the side of the screw 604. The screw 604 is rotatably connected to the fixed frame 4. A motor box 5 is provided outside the motor 601, the driving gear 602 and the driven gear 603. A lifting plate 605 is provided outside the screw 604. A bidirectional linear motor 7 is fixedly installed on the lifting plate 605.
[0025] By adopting the above technical solution, motor 601 drives the active gear 602 to rotate, thereby driving the driven gear 603 to rotate. During the rotation of the driven gear 603, the screw 604 is driven to rotate, so that the lifting plate 605 can move up and down, thereby adjusting the position of the bidirectional linear motor 7.
[0026] The connecting frames 1501 are symmetrically distributed. Slider 1502 is installed on the connecting rod of the two sets of connecting frames 1501 respectively. A rotating plate 1503 is installed on the outside of the slider 1502 through a damping rotating shaft. There are two rotating plates 1503 in each set.

It can clamp the switch cabinet and circuit breaker by cooperating with the baffle 1002.
[0028] Working principle: When using this utility model, first turn on motor 601 to drive screw 604 to rotate, adjust bidirectional linear motor 7 to a suitable height, and then select one or two sets of switch cabinets and circuit breakers as needed. If one set is used, bidirectional linear motor 7 does not need to be turned on. If two sets are needed, bidirectional linear motor 7 can be turned on to adjust the position of lifting frame 8 and lifting frame 9.
[0029] After adjustment, place the switch cabinet or circuit breaker on the placement plate 10 on the lifting frame 8 and lifting frame 9 respectively. After placement, rotate and adjust the position of the clamping frame 1504, and then adjust the position of the clamping plate 1506 to clamp the electrical appliance. Then push the entire service trolley to move it to the required position.
[0030] Furthermore, through the set lifting components, bidirectional linear motor 7, lifting frame one 8 and lifting frame two 9, two sets of switch cabinets and circuit breakers can be placed simultaneously. The bidirectional linear motor 7 can adjust the distance between lifting frame one 8 and lifting frame two 9, thus adapting to switch cabinets and circuit breakers of different heights. With the lifting components, the two lifting frames can be automatically moved to the required position without manual adjustment. In addition, through the auxiliary clamping components set on the two sets of tracks, switch cabinets and circuit breakers of different models and specifications can be clamped, thus solving the problem that existing service trolleys cannot place and transport two or more sets of switch cabinets and circuit breakers at one time.
