Description

Technical Field

[0001] This application relates to the field of maintenance devices, and particularly to a central air-conditioning maintenance device. Background Art

[0002] At present, the central air-conditioning system consists of one or more cold and heat source systems and multiple air-conditioning systems. Different from traditional refrigerant air conditioners (such as single units, VRVs), it centrally processes air to meet comfort requirements. It uses the principle of liquid gasification refrigeration to provide the required cooling capacity for the air-conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air-conditioning system to offset the cooling and heating loads of the indoor environment.

[0003] The indoor units of existing central air conditioners are generally hoisted on the ceiling with the air outlet facing downwards. When maintaining the indoor unit of the central air conditioner, ladders are often used.

[0004] The above-mentioned prior art solutions have the following defects: When using a ladder to maintain the central air conditioner, someone else needs to hand the repair tools to the maintenance personnel. During the process of handing and receiving the tools, there is a situation where the tools may fall and injure people. Utility Model Content

[0005] This application provides a central air-conditioning maintenance device in order to improve the safety of maintenance personnel when maintaining the central air conditioner.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A central air-conditioning maintenance device includes an operation platform, support frames, and a toolbox. There are two support frames. One end of each of the two support frames abuts against the working surface. The other ends of the two support frames are respectively located on both sides of the operation platform and are hinged to the operation platform. The toolbox is fixedly connected to the operation platform, and the toolbox is used to place repair tools.

[0008] By adopting the above solution, the two support frames are opened at an angle until the operation platform is in a horizontal state. The maintenance personnel can climb onto the operation platform through the support frames and then maintain the central air conditioner. Since a toolbox is provided on the operation platform and tools are placed in the toolbox, the maintenance personnel can obtain the operation tools through the toolbox without the need for others to deliver them to the maintenance personnel, avoiding the situation where the tools fall off and injure people or damage the working surface during the delivery process, achieving the effect of improving the safety of maintenance personnel when maintaining the central air conditioner.

[0009] Further, the toolbox includes a first side plate, a second side plate, a bottom plate, and a connecting plate. The first side plate is fixedly connected to the operation platform. The first side plate and the second side plate are arranged opposite to each other. The bottom plate is located between the first side plate and the second side plate. Both ends of the bottom plate are fixedly connected to the first side plate and the second side plate respectively. There are two connecting plates, which are symmetrically arranged. Both connecting plates are fixedly connected to the first side plate, the second side plate, and the bottom plate. The height of the second side plate is lower than that of the first side plate.

[0010] By adopting the above solution, when putting tools into the toolbox or taking tools out of the toolbox, due to the fact that the height of the second side plate is lower than that of the first side plate, the tools can be tilted and placed into the toolbox, and the aperture formed between the first side plate, the second side plate, and the connecting plate is increased, which is convenient for maintenance personnel to take the tools in the toolbox.

[0011] Further, a partition plate is arranged between the first side plate and the second side plate. Both ends of the partition plate are respectively connected to the first side plate and the second side plate. There are several partition plates, and the partition plates are used to divide the toolbox into several units.

[0012] By adopting the above solution, due to the arrangement of several partition plates, the toolbox is divided into several units by the several partition plates. Each unit contains one tool, which avoids the situation that several tools are all placed in one unit, resulting in stacking and inconvenient taking.

[0013] Further, several first dovetail grooves are opened on the first side plate, and a second dovetail groove corresponding to each first dovetail groove is opened on the second side plate. Dovetail bars are fixedly connected to both sides of the partition plate, and the dovetail bars on both sides of the partition plate are respectively inserted and matched with the first dovetail groove and the second dovetail groove.

[0014] By adopting the above solution, since several first dovetail grooves are opened on the first side plate and a second dovetail groove corresponding to each first dovetail groove is opened on the second side plate, the position of each partition plate can be adjusted, and then the distance between adjacent partition plates can be adjusted, so that different sizes of tools can be carried in each unit.

[0015] Further, a guiding plate is fixedly connected to the second side plate, and the guiding plate is integrally arc-shaped.

[0016] By adopting the above solution, by setting the guiding plate, it is convenient to put tools into the toolbox.

[0017] Further, a connecting piece is arranged between the two support frames. Both ends of the connecting piece are respectively fixedly connected to the two support frames, and the connecting piece is made of a soft and tensile material.

[0018] By adopting the above solution, since a connecting piece is arranged between the two support frames, when the two support frames are unfolded at an angle, the connecting piece is straightened, thereby limiting the two support frames.

[0019] Furthermore, a moving component is arranged on the support frame. The moving component includes a moving frame and rollers. The rollers are arranged inside the moving frame and are fixedly connected to the moving frame. Lifting grooves are formed on both sides of the moving frame away from each other. Each lifting groove is slidably connected to the support frame. Locking components are arranged on both sides of the lifting groove. The locking components are used to lock the relative position between the support frame and the lifting groove.

[0020] By adopting the above solution, lifting grooves are formed on both sides of the moving frame, and the lifting grooves are slidably connected to the support frame. Then the moving frame is slidably connected to the lifting member. Since rollers are also connected to the moving frame, when the device needs to be moved, the moving frame is pushed towards the working surface until the rollers are in contact with the working surface and the legs of the support frame are separated from the working surface. After the positional relationship between the support frame and the moving frame is determined, the moving component locks the relative positional relationship between the support frame and the moving frame.

[0021] Furthermore, each locking component includes a locking plate and a locking rod. One end of the locking plate is fixedly connected to the support frame. A threaded hole is formed on the locking plate. The locking rod is threadedly connected to the threaded hole. The locking rod passes through the threaded hole and abuts against the support frame.

[0022] By adopting the above solution, after the positional relationship between the support frame and the moving frame is determined, the locking rod is rotated. The locking rod moves away from the locking plate along the threaded hole until the locking rod abuts against the moving frame. Since the locking plate is fixedly connected to the support frame, when the locking rod abuts against the moving frame, the relative positional relationship between the support frame and the moving frame is locked.

[0023] In summary, the present application has the following technical effects:

[0024] 1. By providing a maintenance device, the two support frames are opened at an angle until the operating platform is in a horizontal state. Maintenance personnel can climb to the operating platform through the support frames, and then repair the central air conditioner. Since a toolbox is arranged on the operating platform and tools are placed in the toolbox, maintenance personnel can take operation tools through the toolbox without others delivering tools to them, avoiding the tools falling off and injuring people or the working surface during the delivery process, achieving the effect of improving the safety of maintenance personnel when repairing the central air conditioner;

[0025] 2. By providing partition plates, several partition plates divide the toolbox into several units, and each unit contains one tool, avoiding several tools being placed in one unit and stacking, resulting in inconvenient taking;

[0026] 3. By providing a connecting member, when the two support frames are unfolded at an angle, the connecting member is straightened, thereby limiting the two support frames. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Referring to Figure 1 , a central air-conditioning maintenance device provided in this embodiment includes an operation platform 1, support frames 2 and a toolbox 3. There are two support frames 2. One end of each of the two support frames 2 abuts against the working surface. The other ends of the two support frames 2 are respectively located on both sides of the operation platform 1 and are both hinged to the operation platform 1. The toolbox 3 is arranged on the operation platform 1. The toolbox 3 is fixedly connected to the operation platform 1. The toolbox 3 is used to place repair tools. The maintenance personnel stand on the operation platform 1 and take tools through the toolbox 3, and then repair the central air-conditioning. In this embodiment, an anti-falling rope is arranged at one end of the operation platform 1 away from the toolbox 3. The anti-falling rope is detachably connected to the operation platform 1.

[0033] Referring to Figure 1 , each support frame 2 includes a support frame 21 and a cross bar 22. A plurality of cross bars 22 are provided. Both ends of each cross bar 22 are respectively fixedly connected to the inner wall of the support frame 21, so that the overall support frame 2 is in the shape of a straight ladder, enabling the maintenance personnel to climb onto the operation platform 1 through the support frame 2; a connecting member 5 is arranged between the two support frames 2. Both ends of the connecting member 5 are respectively fixedly connected to the cross bars 22 of the two support frames 2. In this embodiment, the connecting member 5 is made of a soft and tensile material, for example, a steel wire rope. When the two support frames 2 are unfolded at an angle, the connecting member 5 is straightened, and a triangle is formed by the connecting member 5 and the two support frames 2, thereby limiting the two support frames 2.

[0034] Referring to Figure 1 - Figure 2 , the toolbox 3 is composed of a first side plate 31, a second side plate 32, a bottom plate 33 and two connecting plates 34. The first side plate 31 and the second side plate 32 are arranged correspondingly. The first side plate 31 is fixedly connected to the operation platform 1. The bottom plate 33 is located between the first side plate 31 and the second side plate 32. Both ends of the bottom plate 33 are fixedly connected to the first side plate 31 and the second side plate 32 respectively. There are two connecting plates 34, and the two connecting plates 34 are symmetrically arranged. Both connecting plates 34 are fixedly connected to the first side plate 31, the second side plate 32 and the bottom plate 33. The height of the second side plate 32 is lower than that of the first side plate 31, so that tools can be placed in the toolbox 3 obliquely, and the aperture of the opening formed between the first side plate 31, the second side plate 32 and the connecting plate 34 is increased, which is convenient for maintenance personnel to take the tools in the toolbox 3; a guiding plate 4 is fixedly connected to the second side plate 32. The guiding plate 4 is integrally arc-shaped. The guiding plate 4 is inclined downward from the second connecting plate 34 in a direction away from the second connecting plate 34, which is convenient for putting tools into the toolbox 3.

[0035] Referring to Figure 2 , a plurality of first dovetail grooves 311 are formed on the first side plate 31, and a second dovetail groove 321 corresponding to each first dovetail groove 311 is formed on the second side plate 32. Dovetail bars are fixedly connected to both sides of the partition plate 9. The dovetail bars on both sides of the partition plate are respectively inserted and matched with the first dovetail groove 311 and the second dovetail groove 321, so that the position of each partition plate 9 can be adjusted, and then the distance between adjacent partition plates 9 can be adjusted, so that tools of different sizes can be carried in each unit.

[0036] Referring to Figure 1, the crossbars 22 of each support frame 21 close to the working surface are all cut off, and a moving component 6 is arranged at each cut-off position. Each moving component 6 includes a moving frame 61 and rollers 62. The rollers 62 are fixedly connected to the inner wall of the moving frame 61. Lifting grooves are formed on both sides of the moving frame 61, and both lifting grooves are slidably connected to the crossbar 22; one end of each moving frame 61 away from the working surface is fixedly connected to a handrail rod 8; locking components 7 are arranged at both ends of the two lifting grooves. Each locking component 7 includes a locking plate 71 and a locking rod 72. One end of each locking plate 71 is fixedly connected to the crossbar 22. Threaded holes are formed in each locking plate 71. The locking rod 72 is threadedly connected to the threaded hole, and the locking rod 72 passes through the threaded hole and abuts against the support frame 2; by controlling the sliding of the two lifting grooves and the crossbar 22, the position of the moving frame 61 relative to the working surface can be controlled until the rollers 62 abut against the working surface and the support frame 21 is separated from the working surface. At this time, rotate the locking rod 72, and the locking rod 72 moves towards the direction close to the lifting groove until the locking rod 72 abuts against the lifting groove, thereby locking the relative position between the lifting groove and the support frame 21. Then, by pushing the device, the device can be displaced along the working surface.

[0037] The implementation principle of a central air-conditioning maintenance device in an embodiment of the present application is as follows: First, open the two support frames 2 at an angle until the connecting member 5 is straightened; then the maintenance personnel stand on the operation platform 1 by climbing the support frame 2, and then take the tools in the toolbox 3 to repair the air conditioner; when the device needs to be moved, push each handrail rod 8 towards the end close to the working surface, and each handrail rod 8 drives each moving frame 61 to move towards the direction close to the working surface until each roller 62 abuts against the working surface and each support frame 21 is separated from the working surface. Then, push the device to make the device displace along the working surface.

[0038] This specific embodiment is only an explanation of the present application, and it is not a limitation of the present application. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
