[0024] The present invention provides the following specific embodiments:

[0025] like Figure 1-4As shown, this utility model provides an armored withdrawable AC metal-enclosed switchgear, comprising a housing 1 consisting of an instrument compartment 1.1, a truck compartment 1.2, a busbar compartment 1.3, a cable compartment 1.4, and a storage compartment 1.5. The storage compartment 1.5 is located at the bottom, the cable compartment 1.4 is located above the storage compartment 1.5, the truck compartment 1.2 and the busbar compartment 1.3 are arranged sequentially from front to back above the cable compartment 1.4, and the instrument compartment 1.1 is located above the truck compartment 1.2. The truck compartment 1.2 contains a circuit breaker truck 2, and the storage compartment 1.5 contains a lifting assembly. The lifting assembly includes an upper mounting plate 3, a lower base plate 4, and a lifting drive assembly disposed between the upper mounting plate 3 and the lower base plate 4. The upper surface of the upper mounting plate 3 is provided with a travel rail 12, and the circuit breaker trolley 2 can move on the travel rail 12. The storage chamber 1.5 is provided with a first groove slide rail 5, and the lower base plate 4 is equipped with a slider that cooperates with the first groove slide rail 5. When it is necessary to move the circuit breaker trolley 2, the lifting assembly is pulled out of the storage chamber 1.5, and then the upper mounting plate 3 is raised so that the travel rail 12 on the upper mounting plate 3 is aligned with the travel rail in the trolley chamber 1.2.

[0026] Furthermore, the lifting drive assembly is a scissor lift assembly, including a scissor arm and a hydraulic cylinder, with the hydraulic cylinder driving the scissor arm to move.

[0027] Furthermore, there are two first grooved slide rails 5, which are respectively installed on the left and right inner walls of the storage chamber 1.5; the sliders include a first slider 10 and a second slider 11, the first slider 10 is arranged on the same side as the first storage chamber door 13, and the second slider 11 is arranged on the same side as the second storage chamber door 14; the front of the storage chamber 1.5 is provided with a double door composed of the first storage chamber door 13 and the second storage chamber door 14, the inner wall of the first storage chamber door 13 is equipped with a second grooved slide rail 6, and the first storage chamber door 13 can be opened so that the axis of the second grooved slide rail 6 coincides with the axis of the first grooved slide rail 5 located on that side; the inner wall of the second storage chamber door 14 is equipped with a third grooved slide rail 7, and the second storage chamber door 14 can be opened so that the axis of the third grooved slide rail 7 coincides with the axis of the first grooved slide rail 5 located on that side.

[0028] Furthermore, the front end of the third groove slide rail 7 extends beyond the edge of the second storage chamber door 14, while the front end of the second groove slide rail 6 does not extend beyond the edge of the first storage chamber door 13; the front end of the second groove slide rail 6 is not closed, while the front end of the third groove slide rail 7 is closed; the first slider 10 is cuboid, and the second slider 11 is cylindrical, with the second slider 11 arranged vertically and its cylindrical surface tangent to the rear end face of the lower substrate 4; when the axis of the second groove slide rail 6 coincides with that of the first groove slide rail 5 located on that side, there is a gap between the second groove slide rail 6 and the first groove slide rail 5 located on that side, and at this time, the length of the first slider 10 is greater than the length of the gap in the axial direction of the second groove slide rail 6.

[0029] Furthermore, a buckle 8 consisting of a card and a slot is provided between the box body 1 and the first storage room door 13. When the buckle 8 is combined, the axis of the second groove slide rail 6 and the first groove slide rail 5 located on that side coincides. A buckle 8 consisting of a card and a slot is provided between the box body 1 and the second storage room door 14. When the buckle 8 is combined, the axis of the third groove slide rail 7 and the first groove slide rail 5 located on that side coincides.

[0030] Furthermore, the slotting direction of the first grooved slide rail 5, the second grooved slide rail 6, and the third grooved slide rail 7 is downward, the lower base plate 4 is provided with casters, and the lower side of the housing 1 is provided with support legs.

[0031] Furthermore, the upper inner wall of the storage chamber 1.5 is also provided with a groove 9, which corresponds to the position of the travel rail 12 of the upper mounting plate 3.

[0032] In this embodiment, the working process is as follows:

[0033] like Figure 5 As shown, when the circuit breaker trolley 2 needs to be moved to the test position for inspection, the first storage compartment door 13 and the second storage compartment door 14 are opened, the lifting assembly is pulled out, and the upper mounting plate 3 is driven to rise so that the travel rail 12 on the upper mounting plate 3 is aligned with the travel rail in the trolley compartment 1.2. At this time, due to the obstruction of the cable compartment 1.4 box door, the lifting assembly needs to be moved to a position not below the cable compartment 1.4 box door before the upper mounting plate 3 is raised. After the upper mounting plate 3 passes the cable compartment 1.4 box door, the travel rail 12 on the upper mounting plate 3 is aligned with the travel rail in the trolley compartment 1.2. Finally, the circuit breaker trolley 2 is moved to the test position, and the upper mounting plate 3 provides support for the circuit breaker trolley 2.

[0034] like Figure 6 As shown, when the circuit breaker trolley 2 needs to be completely removed for inspection, the first storage compartment door 13 and the second storage compartment door 14 are opened, the lifting assembly is pulled out, and the upper mounting plate 3 is driven to rise so that the travel rail 12 on the upper mounting plate 3 is aligned with the travel rail in the trolley compartment 1.2. After the circuit breaker trolley 2 is moved onto the upper mounting plate 3, the lifting assembly is moved until the first slider 10 disengages from the second slotted slide rail 6, and the second slider 11 is located at the front end of the third slotted slide rail 7. At this time, the rear end face of the lower base plate 4 is in front of the second storage compartment door 14. Since the second slider 11 is cylindrical, the lower base plate 4 can rotate, so as not to affect the activities of the staff in space. After the inspection is completed, the lower base plate 4 is rotated back, the first slider 10 returns to the second slotted slide rail 6, and finally the trolley is reinstalled in the trolley compartment 1.2, and the lifting assembly is reinstalled in the storage compartment 1.5.

[0035] During the installation and construction phase of the switchgear, the lifting assembly is located in the storage chamber 1.5. The upper mounting plate 3 is raised (at this time, the travel rail 12 will enter the groove 9 to avoid being damaged), and the entire switchgear is lifted for easy movement.

[0036] After the lifting assembly located in storage chamber 1.5 is slid out, it supports the handcart. The movement trajectory of the lifting assembly is fixed, eliminating the need for docking with the transport trolley and improving work efficiency. When the lifting assembly is in storage chamber 1.5, it can be raised and moved by the casters at the bottom of the lifting assembly, facilitating the transportation of the switchgear.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
