[0022] The force-applying structure 5 includes an electric push rod 51, a concave plate 52, teeth 53 and a gear 54. The electric push rod 51 is fixed on the left side of the operating table 3. The output end of the electric push rod 51 is fixed to the bottom of the concave plate 52. There are several teeth 53, which are respectively fixed on the opposite sides of the concave plate 52. The inside of the gear 54 is fixed to the surface of the rotating shaft on the left side of the baffle plate 4. The concave plate 52 is meshed with the gear 54 through the teeth 53. In this way, when the baffle plate 4 is driven to deflect, the electric push rod 51 can be started, and the concave plate 52 can be driven to move downward, and then the gear 54 and the baffle plate 4 are driven to deflect through the teeth 53.
[0023] The fixing structure 12 includes a fixing plate 121, a screw 122, a crank 123 and a fixing plate 124. The fixing plate 121 is fixed to the outer side of the base 1. The surface of the screw 122 is connected to the internal thread of the fixing plate 121. One end of the screw 122 is fixed to one side of the crank 123, and the other end of the screw 122 is fixed to one side of the fixing plate 124. In this way, after the device is moved to the specified position, the crank 123 can be rotated, and the screw 122 and the fixing plate 124 can be driven to move downward, so that the fixing plate 124 is in contact with the ground, thereby improving the stability of the device when it is placed later.
[0024] Support plates 6 are fixedly connected to the front and rear of the left side of the operating table 3, and the surface of the support plate 6 is movably connected to the inside of the concave plate 52, so that the concave plate 52 can be auxiliary supported and its stability can be maintained when it moves up and down.
[0025] A placement box 13 is provided on the left side of the top of the operating table 3, and a plurality of placement slots are provided on the top of the placement box 13, so that it is convenient to place some of the repaired parts inside the placement slots to avoid loss.
[0026] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.
[0027] Working principle: When in use, the device can be moved to the desired position, and then the base 1 can be fixed by the fixing structure 12. After the fixing is completed, the staff can stand inside the operating table 3, and then with the lifting and lowering of the lifting mechanism 2, the operating table 3 will be driven upward to the position close to the central air conditioner. After lifting to the specified height, in order to prevent small parts on the air conditioner from falling down and accidentally injuring others during maintenance, the front and rear chain two shielding plates 4 can be driven by the force structure 5 to deflect to the opposite side, thereby shielding the front and rear positions under the central air conditioner. Later, during the maintenance process, in order to avoid lifting and lowering back and forth to take the corresponding tools, the motor 7 can be started at this time, and the winding roller 8 can be driven to rotate, so that the pull rope 10 is in an unwinding state, and the tool box 11 is driven to fall downward. Finally, the required tools can be placed inside the tool box 11 for lifting and taking.
