There is also a type of central air-conditioning that uses refrigerant Freon VRV air-conditioning units. It is different from ordinary household air-conditioning and can be used in large-scale buildings. At present, when maintaining a central air-conditioning main unit, a support device is needed to carry the disassembled central air-conditioning main unit.

[0003] For example, the utility model with the patent publication number CN219426748U provides a support device for the maintenance of a central air-conditioning main unit, including a maintenance table.

[0024] The following describes the implementation manners of the present utility model by specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figures 1 - 5 , the present utility model provides a support device for the maintenance of a central air-conditioning host, including a bottom plate 1. Universal moving wheels 2 are provided at the bottom corners of the bottom plate 1. The number of the universal moving wheels 2 is at least two pairs. The universal moving wheels 2 can provide mobility for the entire support device, so as to move in the maintenance area of the central air-conditioning host. An elevating mechanism 3 is arranged on the bottom plate 1. A main maintenance bearing plate 5 for receiving parts of the central air-conditioning host is mounted on the elevating mechanism 3. The elevating mechanism 3 can provide lifting power for the main maintenance bearing plate 5. A pair of auxiliary maintenance bearing plates 6 are connected to both sides of the main maintenance bearing plate 5 through hinges. The auxiliary maintenance bearing plates 6 can adjust the supporting area of the main maintenance bearing plate 5 according to the area of the maintenance space or the size of the central air-conditioning host. At least one pair of extension assemblies 7 are arranged on the elevating mechanism 3 and the pair of auxiliary maintenance bearing plates 6. In this application, at least one pair of extension assemblies 7 are provided. The extension assemblies 7 are used to control the rotation of the auxiliary maintenance bearing plates 6 on the main maintenance bearing plate 5. At least one pair of auxiliary support assemblies 8 are arranged on the main maintenance bearing plate 5 and the pair of auxiliary maintenance bearing plates 6. In this application, at least one pair of auxiliary support assemblies 8 are provided.

[0026] Brake pads are arranged on the universal moving wheels 2. The brake pads can enable the universal moving wheels 2 to have a braking function, so that the entire support device can be more stable in the stopped state.

[0027] The elevating mechanism 3 includes an elevating device 31. The elevating device 31 is fixedly connected to the top of the bottom plate 1. The output end of the elevating device 31 is fixedly connected to an elevating plate 32. In this application, the elevating device 31 can adopt an elevating motor as the elevating equipment, and two pairs of elevating devices 31 can be arranged at the bottom corners of the top of the bottom plate 1. In this way, the elevating device 31 can pull the elevating plate 32 to perform vertical lifting actions, so as to provide lifting power for the main maintenance bearing plate 5. In this way, when the parts of the central air-conditioning host are disassembled and placed on the main maintenance bearing plate 5 for maintenance, the position height of the parts of the central air-conditioning host can be effectively adjusted to meet the maintenance height requirements of the operator.

[0028] A column 4 is fixedly connected to the elevating plate 32. The main maintenance bearing plate 5 is fixedly connected to the column 4. Tool boxes 51 are arranged at both ends of the main maintenance bearing plate 5. Accessories for the maintenance of the central air-conditioning host can be stored in the tool boxes 51.

[0029] The stretching component 7 includes a lead screw 71 which is rotatably connected to the lifting plate 32 and the main maintenance bearing plate 5. A threaded sleeve 72 is threadedly connected to the lead screw 71. A pair of first struts 73 are hinged to the threaded sleeve 72. The ends of the first struts 73 facing away from the threaded sleeve 72 are hinged to the secondary maintenance bearing plate 6.

[0030] A rotating device 9 is fixedly connected to the bottom of the lifting plate 32. The output end of the rotating device 9 passes through the lifting plate 32 and is fixedly connected to one end of the lead screw 71. The rotating device 9 can use a forward and reverse rotating motor as the rotating equipment, and the rotating motor is a self-locking motor.

[0031] Specifically, by driving the lead screw 71 to rotate in the positive or negative direction through the rotating device 9, under the limited rotation of the hinge on the secondary maintenance bearing plate 6, the feeding of the threaded sleeve 72 on the thread of the lead screw 71 can pull the secondary maintenance bearing plate 6 through the first strut 73. In this way, with the function of the hinge connection, a pair of secondary maintenance bearing plates 6 can perform horizontal and vertical state actions on both sides of the main maintenance bearing plate 5. When the secondary maintenance bearing plate 6 is horizontally arranged, it can expand the supporting area of the main maintenance bearing plate 5. When the secondary maintenance bearing plate 6 is vertically arranged, without affecting the space occupancy rate, the main maintenance bearing plate 5 can be used alone as the support for the central air-conditioning main unit.

[0032] The auxiliary support component 8 includes a slide rail 81 which is fixedly connected to the bottom of the main maintenance bearing plate 5. A pair of sliding seats 82 are slidably connected to the slide rail 81. A second strut 83 is hinged to each sliding seat 82. The end of the second strut 83 facing away from the sliding seat 82 is hinged to the secondary maintenance bearing plate 6. When a pair of secondary maintenance bearing plates 6 perform horizontal and vertical state actions on both sides of the main maintenance bearing plate 5, the second struts 83 hinged to the secondary maintenance bearing plate 6 can drive the sliding seats 82 to slide adaptively on the slide rail 81. When the secondary maintenance bearing plate 6 and the main maintenance bearing plate 5 are horizontally arranged, while the first strut 73 supports the bottom of the secondary maintenance bearing plate 6, the second strut 83 can further provide a fulcrum for the secondary maintenance bearing plate 6, so as to ensure the supporting strength when the secondary maintenance bearing plate 6 is horizontally arranged.

[0033] It should be noted that a power supply and a controller can be arranged on the support device of the present application. The controller can be electrically connected to the lifting device 31 and the rotating device 9 respectively through wires via the power supply, so as to facilitate controlling the operation of the lifting device 31 and the rotating device 9.
