A workbench is arranged above the base frame 1. 2. The workbench 2 includes a guardrail to protect the workers working on the workbench 2. The workbench 2 is provided with side grooves 14 on both sides of the guide block. The guide block slides with the adjacent side grooves 14. In the above, the guide block is driven to move upward or downward along the side frame 4 by the rotation of the screw rod 6. The opposite side of the side frame 4 is provided with a vertically distributed mounting groove. The screw rod 6 is located inside the mounting groove. The lower end of the mounting groove extends downward to the upper side of the bottom frame 1. The two motors are fixedly installed on the upper side of the bottom frame 1, and the guide block is slidably connected to the inside of the mounting groove.

[0033] Two parallel brackets 8 are fixedly connected to the upper side of the bottom frame 1 and located between the two side frames 4. The swing arm 3 is rotatably connected between the upper ends of the brackets 8, and the cylinder 7 is rotatably connected between the lower ends of the brackets 8. The cylinder 7 is also electrically connected to the controller, and the extension and contraction of the cylinder 7 is controlled by the controller. The upper end of the cylinder 7 is rotatably connected to the rear end of the swing arm 3. The swing arm 3 includes a short arm end and a long arm end located at the front and rear sides of the bracket 8. The short arm end of the swing arm 3 is located in the rear direction of the bracket 8, and the long arm end of the swing arm 3 is located in the front direction of the bracket 8. The upper end of the above-mentioned cylinder 7 is connected to the short arm end of the swing arm 3, and the swing arm 3 is driven to swing by the extension and contraction of the cylinder 7;

[0034] The lower side of the workbench 2 is fixedly connected to two support plates arranged in parallel and support blocks are included at the four corners of the lower side of the workbench 2. A support shaft 15 is rotatably connected between the lower ends of the two support plates. The front end of the swing arm 3 is fixedly connected to the outer side of the support shaft 15.

The counterweight frame 12 is rotatably connected, and the above-mentioned middle cylinder 7 can be replaced by a hydraulic cylinder or an electric push rod. When using the anti-sway lifting equipment for interior decoration ceiling, it is necessary to place a counterweight, such as a sandbag, on the counterweight frame 12 first. When the cylinder 7 retracts, it drives the short arm end of the swing arm 3 to rotate downward and the long arm end to rotate upward. During the process, the cylinder 7 drives the side wheel 17 to rotate through the fixed shaft, and then the side wheel 17 drives the fixed rod 18 to act on the connecting rod 10, so that the connecting rod 10 swings and drives the connecting rod 2 11 at the lower end to push the counterweight frame 12 to move forward along the first guide seat 13, thereby adjusting the center of gravity position of the anti-sway lifting equipment for interior decoration ceiling.

[0036] The slot is extended to the rear side of the workbench 2 , and a sliding plate 9 is slidably connected to the inner side of the rear end of the workbench 2 .

[0037] The rotation connection between the swing arm 3 and the bracket 8 includes a side shaft fixedly connected to the swing arm 3, and the outer side surfaces of the side shafts are fixedly connected to the top arm 5. During the swinging process of the swing arm 3, the top arm 5 swings along with the swing arm 3, and the lower end of the top arm 5 is rotationally connected to the auxiliary arm 19. An elastic telescopic rod 21 is rotationally connected between the top arm 5 and the auxiliary arm 19. The end of the auxiliary arm 19 away from the top arm 5 is rotationally connected to the roller 23. The lower side surface of the workbench 2 is fixedly connected to the second guide seat 16, and the roller 23 extends into the inner side of the second guide seat 16 for rolling connection. The elastic telescopic rod 21 includes a plurality of guide wheels, and the guide wheels 23 are connected to the second guide seat 16. It includes an outrigger rod 25, a spring 26 and a sleeve 27, one end of the outrigger rod 25 extends into the interior of the sleeve 27 and the other end is rotatably connected to the top arm 5, one end of the sleeve 27 away from the outrigger rod 25 is rotatably connected to the auxiliary arm 19, the spring 26 is fixedly connected between the outrigger rod 25 and the sleeve 27, the lower side of the auxiliary arm 19 is fixedly connected with a fixing seat 20, the outer side surface of the sleeve 27 is fixedly connected with an arc block 22, and the fixing seat 20 is provided with an arc groove that cooperates with the arc block 22, the above-mentioned middle arc block 22, the swing arm 3, the auxiliary arm 19 and the top arm 55 are all made of hard alloy steel.

[0038] A connecting shaft 24 is fixedly connected between the lower ends of the two auxiliary arms 19 , and the connecting shaft 24 is coaxially distributed with the two rollers 23 . In the above, the connecting shaft 24 facilitates the two auxiliary arms 19 to move simultaneously.

[0039] Working principle: After placing the sandbag on the counterweight frame 12, the rear side of the anti-sway lifting equipment for the interior decoration ceiling is leaned against the position of the ceiling operation. In the process of controlling the cylinder 7 to retract through the controller, the screw 6 is controlled to rotate at an unfixed speed. Here, the rotation of the screw 6 can be controlled according to the speed change of the cylinder 7 driving the swing arm 3 to push the workbench 2 to rise, and the control is programmed in advance to ensure the horizontal lifting of the workbench 2 during the process. In the process of the cylinder 7 driving the long arm end of the swing arm 3 to rotate upward, the workbench 2 is driven to move upward. During the process, the screw 6 is supported in the side groove 14 by the guide block to provide auxiliary support for the workbench 2. The forward and backward movement of the workbench 2 is achieved by the sliding cooperation between the side groove 14 and the guide block. During the process, the swing arm 3 drives the top arm 5 to rotate, but due to the telescopic characteristics of the elastic telescopic rod 21, the top arm 5 is rotated. During the rotation of the arm 5 and the auxiliary arm 19, a certain pulling force is provided, so that the auxiliary arm 19 supports the workbench 2 through the roller 23. During the process, the arc block 22 can be rotated to extend into the arc groove. After the elastic telescopic rod 21 is stretched to allow the arc block 22 to extend into the arc groove, the workbench 2 is further supported auxiliaryly. In addition, during the rotation of the cylinder 7, the fixed rod 18 is driven to rotate by the side wheel 17, and then the fixed rod 18 pushes the connecting rod 10 to swing to enlarge the stroke, and then the connecting rod 10 pushes the connecting rod 2 11 to move the counterweight frame 12 to the front side, thereby adjusting the center of gravity of the anti-sway lifting equipment of the interior decoration ceiling, improving the structural stability of the workbench 2 after extending to the rear side, and also achieving the anti-sway effect. The sliding plate 9 can be detached from the slot as needed, and the ceiling materials can be handed over to the workers on the workbench 2 from the slot.

[0040] Embodiment 2:

[0041] The difference between this embodiment and the first embodiment is that the spring 26 in the first embodiment is replaced by a rubber strip to provide elasticity. Initially, the angle between the top arm 5 and the auxiliary arm 19 decreases due to the elasticity of the rubber strip. During the process of increasing the angle between the top arm 5 and the auxiliary arm 19, the rubber strip is stretched.

[0042] Embodiment three:

[0043] The difference between this embodiment and the first embodiment is that rubber sheets are adhered to the inner and outer sides of the curve of the arc block 22 to increase the resistance between the arc block 22 and the arc groove.

[0044] Although 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.
