[0042] This application provides an embodiment of a transport trolley for a circuit breaker hydraulic mechanism. Figure 1 .

[0043] The transport trolley for the circuit breaker hydraulic mechanism in this embodiment includes: a transport trolley body, which includes a top plate 1, a middle plate 2, a chassis 3 and a split hydraulic jack. A universal wheel 5 is provided at the bottom of the chassis 3, and the middle plate 2 is provided directly above the chassis 3, and the middle plate 2 is rotatably connected to the chassis 3; a self-rotating power device for driving the middle plate 2 to rotate is provided on the chassis 3, and the split hydraulic jack includes an oil cylinder and multiple pump tops 4 provided on the top of the middle plate 2, and the multiple pump tops 4 are all connected to the oil cylinder, the top plate 1 is provided directly above the middle plate 2, and the output ends of the multiple pump tops 4 are all connected to the lower surface of the top plate 1; multiple laser ranging sensors are evenly arranged on the outer periphery of the chassis 3.

[0044] It should be noted that this shipping trolley has the functions of free movement, vertical lifting and self-rotation. Among them, by utilizing the self-rotating power device to drive the middle plate 2 to self-rotate, it is suitable for small spaces and can effectively prevent the surrounding obstacles from bumping into the precision electronic components during the horizontal movement of the equipment; the split hydraulic jack is used to control the lifting and lowering of the top plate 1, which is more flexible and more stable, and can prevent the sudden drop due to abnormal pressure from causing harm to the staff and equipment (release the return oil switch and the piston automatically returns to its position). In addition, a plurality of laser ranging sensors are evenly arranged on the outer periphery of the chassis 3, which can detect the distance between the chassis 3 and the surrounding obstacles in real time during the movement, further avoiding the bumping of the equipment.

[0045] The above is the first embodiment of a transport trolley for a circuit breaker hydraulic mechanism provided by the embodiment of the present application. The following is the second embodiment of a transport trolley for a circuit breaker hydraulic mechanism provided by the embodiment of the present application. For details, please refer to Figures 1 to 3 .

[0046] The transport trolley for the hydraulic mechanism of the circuit breaker in this embodiment includes: a transport trolley body, the transport trolley body includes a top plate 1, a middle plate 2, a chassis 3 and a split hydraulic jack, a universal wheel 5 is provided at the bottom of the chassis 3, the middle plate 2 is provided directly above the chassis 3, and the middle plate 2 is rotatably connected to the chassis 3; a self-rotating power device for driving the middle plate 2 to rotate is provided on the chassis 3, the split hydraulic jack includes an oil cylinder and a plurality of pump tops 4 provided on the top of the middle plate 2, the plurality of pump tops 4 are all connected to the oil cylinder, the top plate 1 is provided directly above the middle plate 2, and the output ends of the plurality of pump tops 4 are all connected to the lower surface of the top plate 1, and when the middle plate 2 rotates, the top plate 1 can be driven to rotate synchronously by the pump tops 4; a plurality of laser ranging sensors are evenly provided on the outer periphery of the chassis 3.

[0047] It should be noted that: by connecting multiple pump tops 4 respectively through an oil cylinder, multiple pump tops 4 can be controlled to rise and fall synchronously, ensuring that the heavy objects remain stable during the lifting process, and at the same time avoiding the tilt of the top plate 1 caused by inconsistent heights of the pump tops 4.

[0048] Specifically, such as Figure 2 As shown, the self-rotating power unit includes a motor fixed to the chassis 3, a driving wheel 7 provided on the motor output shaft, and a driven wheel drivingly connected to the driving wheel 7. The driven wheel is fixedly connected to the center disk 2. It is understood that the motor can be equipped with a built-in wireless connection unit such as WiFi, RFID, and Bluetooth, so that the forward and reverse rotation of the motor output shaft can be controlled by remote control, thereby controlling the rotation direction and angle of the center disk 2.

[0049] The driven wheel can be an annular internal gear 8. A through hole 6 is provided at the center of the middle disk 2. The annular internal gear 8 is fixed in the through hole 6. The visual design facilitates maintenance and repair. It is understood that the annular internal gear 8 can be integrally formed with the middle disk 2.

[0050] like Figure 3 As shown, a first annular groove is concentrically opened on the lower surface of the middle plate 2, and a second annular groove is concentrically opened on the upper surface of the chassis 3. The diameters of the first annular groove and the second annular groove are the same. A plurality of balls 9 are arranged in the second annular groove, and the middle plate 2 is rotatably connected to the chassis 3 through the balls 9.

[0051] The distance between the lower surface of the middle plate 2 and the upper surface of the bottom plate 3 is equal to half the diameter of the ball 9, which can be used to observe the wear of the ball 9 and reduce the contact area between the ball 9 and the groove, thus preventing the middle plate 2 from falling off and effectively reducing the sliding resistance.

[0052] A mounting groove for placing the pump top 4 is provided on the top of the middle plate 2. The shape of the mounting groove matches the shape of the bottom of the pump top 4. The pump top 4 is limited by the mounting groove to prevent displacement of the pump top 4. At the same time, by using gravity to fix the pump top 4, the installation and disassembly of the pump top 4 can be more convenient, which is convenient for later maintenance. In addition, when not in use, the pump top 4 can be taken out of the mounting groove to reduce the overall volume of the device.

[0053] It is understood that the pump top 4 can also be fixedly mounted on the top of the middle plate 2 via a fixing member. Similarly, the bottom of the top plate 1 can be provided with a retaining groove that matches the shape of the output end of the pump top 4, or the output end of the pump top 4 can be fixed to the bottom of the top plate 1 via a fixing member. The specific configuration can be determined according to actual conditions and is not limited here.

[0054] In this embodiment, there are four pump tops 4, each connected to a four-way valve by a hydraulic cylinder. The four pump tops 4 are symmetrically distributed along the center of the center plate 2. The hydraulic cylinders can be individually provided and connected to the four pump tops 4 via flexible hoses, effectively reducing the size of the shipping cart. Furthermore, the hydraulic cylinders can be equipped with an external LCD display and built-in wireless connectivity such as WIFI, RFID, and Bluetooth, allowing the pump tops 4 to be raised and lowered remotely, making it even more convenient to use.

[0055] A magnetic part can be provided on the top of the top plate 1 to realize integrated consignment adsorption, making the device more stable after being placed and avoiding displacement or falling during movement.

[0056] A brake plate can be provided on the universal wheel 5, which can be used to stably fix the consignment trolley, facilitate the adjustment of the transfer direction of the transfer trolley, and improve the transfer efficiency.

[0057] The diameters of the top plate 1, the middle plate 2 and the bottom plate 3 are equal; the material of the shipping trolley body can be stainless steel, which is more sturdy and durable.

[0058] This trolley for the circuit breaker hydraulic mechanism boasts a simple structure and ease of use, making it suitable for transporting objects of all sizes. It is particularly well-suited for operations within the confines of the mechanism box or on obstructed horizontal surfaces. Its high efficiency allows for efficient heavy object handling while also ensuring safety and reliability, fully ensuring the safety of both equipment and personnel. Furthermore, its vertical, visual design facilitates maintenance and inspection, while utilizing gravity to secure the pump top 4, eliminating the tedious maintenance and inspection required by traditional screw fastenings.

[0059] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
