DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides: an auxiliary device for central air conditioning engineering maintenance, such as Figure 1-4 As shown, it includes an installation box 1, and several groups of hydraulic rods 9 are fixedly arranged at the bottom of the installation box 1. The working ends of the several groups of hydraulic rods 9 are jointly fixed with a working board 3. After the staff stands on the upper surface of the working board 3, the working board 3 is lifted by the several groups of hydraulic rods 9, so as to facilitate the maintenance personnel to repair the central air-conditioning. Two groups of sliding guardrails 4 are slidingly arranged on the upper surface of the working board 3, and two groups of fixed guardrails 5 are fixedly installed on the upper surface of the working board 3 and on the corresponding surfaces of the two groups of sliding guardrails 4. Two groups of telescopic lying boards 2 are slidingly arranged on both sides of the working board 3 close to the two groups of sliding guardrails 4, and a driving component 7 for driving the telescopic lying board 2 to be telescoped inside the working board 3 is arranged on the side of the working board 3. The two groups of sliding guardrails 4 are consistent with the extended position of the two groups of telescopic lying boards 2. When the maintenance personnel need to lie down, the sliding guardrail 4 is moved, thereby ensuring that the maintenance personnel can lie on the upper surface of the working board 3 to repair the central air-conditioning.

[0022] The driving assembly 7 includes a toothed plate 10, a transmission gear 11, a first connecting gear 12, a first belt 13 and a second connecting gear 14. The toothed plate 10 is fixedly mounted on the lower surface of the telescopic lying plate 2, the transmission gear 11 is meshedly arranged on the lower surface of the toothed plate 10, and the transmission gear 11 is rotatably arranged inside the working plate 3. The first connecting gear 12 is fixedly mounted on the side of the transmission gear 11 through a group of connecting columns. The first belt 13 is meshedly sleeved on the outer arc surface of the first connecting gear 12 and the second connecting gear 14, and the second connecting gear 14 is rotatably arranged on the side of the working plate 3. When the second connecting gear 14 rotates, the first connecting gear 12 is driven to rotate by the first belt 13, and the first connecting gear 12 drives the transmission gear 11 to rotate, thereby driving the telescopic lying plate 2 to extend and retract inside the working plate 3 through the toothed plate 10, and the toothed plate 10 and the transmission gear 11 are located inside the working plate 3, and a space for the toothed plate 10 to move and the transmission gear 11 to rotate is provided inside the working plate 3, thereby avoiding scratching of the transmission gear 11 with the inside of the working plate 3 when it rotates.

[0023] The driving assembly 7 also includes a first driving gear 15, a second belt 16, a second driving gear 17 and a turntable 18. The first driving gear 15 is fixedly mounted on the side of the second connecting gear 14 away from the working plate 3 through another set of connecting columns. The second belt 16 is meshed and sleeved on the outer arc surface of the first driving gear 15 and the second driving gear 17. When the second driving gear 17 rotates, the second belt 16 drives the first driving gear 15 to rotate, thereby driving the second connecting gear 14 to rotate.

[0024] The turntable 18 rotates the inner side of a group of fixed guardrails 5, and the second driving gear 17 penetrates the fixed guardrail 5 and is fixedly connected to the turntable 18 through a group of rotating columns. The maintenance personnel manually shake the turntable 18 on the upper surface of the working plate 3, and the turntable 18 drives the second driving gear 17 to rotate through the rotating columns, thereby driving the telescopic lying plate 2 to be telescoped inside the working plate 3 through the driving assembly 7, and the two groups of driving assemblies 7 do not contact each other to avoid affecting the movement of the two groups of telescopic lying plates 2 inside the working plate 3.

[0025] The two groups of sliding guardrails 4 are fixedly installed with limiting protrusions 19 at the bottom ends, and the upper surface of the working plate 3 is provided with two groups of sliding grooves 20 corresponding to the two groups of limiting protrusions 19. The limiting protrusions 19 are set as convex blocks, thereby ensuring that the sliding guardrails 4 can only move in a straight line along the sliding grooves 20, thereby preventing the sliding guardrails 4 from falling from the upper surface of the working plate 3.

[0026] The corresponding surfaces of the two groups of sliding guardrails 4 are fixedly installed with mounting blocks 23, and the upper surfaces of the two groups of mounting blocks 23 are penetrated by positioning rods 21, and the upper surface of the working plate 3 is provided with a plurality of positioning holes 22 corresponding to the positioning rods 21. When the maintenance personnel do not need to lie down for maintenance, the working plate 3 is surrounded by the two groups of sliding guardrails 4 and the two groups of fixed guardrails 5, so as to protect the maintenance personnel and prevent them from falling from the upper surface of the working plate 3. When the maintenance personnel need to lie down, they pull out the positioning rod 21 and then move the sliding guardrail 4. After the sliding guardrail 4 is moved to one end, the positioning rod 21 is penetrated by the mounting block 23 and inserted into the corresponding positioning hole 22, so as to fix the position of the sliding guardrail 4, thereby making it convenient for the maintenance personnel to lie down for maintenance of the central air conditioner.

[0027] A standing groove 6 is provided on the upper surface of the work board 3, and a safety belt 8 is fixedly installed inside the standing groove 6. When the maintenance personnel lies on the upper surface of the work board 3, the maintenance personnel is fixed by the safety belt 8 to prevent the maintenance personnel from falling from the upper surface of the work board 3.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
