Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment installation, in particular to a ventilation equipment installation lifting platform. Background Art

[0002] In order to ensure people's life safety, the windows of current high-rise office buildings and residences are usually not fully opened, resulting in poor air circulation in the house. Therefore, in order to ensure the quality of indoor air, people usually choose to install ventilation equipment. The ventilation equipment sends sufficient fresh air that has been filtered and dust-removed into the indoor space, while expelling the dirty air in the room to achieve the purpose of improving indoor air quality.

[0003] Since ventilation equipment is usually installed on the ceiling or suspended ceiling, and it is installed as an integral whole and is heavy, it is very dangerous to rely on a few decoration workers to lift it up with ladders for installation. Not only may the equipment fall, but it may also cause unnecessary casualties.

[0004] The current installation lifting platform can only meet the lifting height requirements, but there is no limiting component on its surface, and because the supporting point of the scissor frame will move to one side when it is lifted and extended, it is easy to cause the top lifting component to tilt.

[0005] In order to solve the above problems, we have made improvements and proposed a ventilation equipment installation lifting platform. Utility Model Content

[0010] As a preferred technical solution of the utility model, the hydraulic telescopic rod is rotatably installed on the inner bottom surface of the support base, a connecting ring is fixedly installed on the top of the hydraulic telescopic rod, a connecting rod is rotatably connected between the central connection points of the lower part of the scissor frame, the connecting ring is sleeved at the center of the connecting rod, and the connecting ring is rotatably connected to the connecting rod.

[0011] As a preferred technical solution of the utility model, the two bidirectional threaded rods are both rotatably connected to the inner surface of the fixed plate, the two ends of the two bidirectional threaded rods are both sleeved with sliders, the sliders are both threadedly connected to the bidirectional threaded rods, the sliders are slidably connected to the inner surface of the fixed plate, two servo motors are fixedly installed on the outer surface of the fixed plate, and the two bidirectional threaded rods are coaxially fixedly connected to the rotating shaft of a servo motor respectively.

[0014] The beneficial effects of the utility model are: this type of ventilation equipment installation lifting platform provides stable lifting support for the scissor frame through the hydraulic telescopic rod. When the scissor frame is extended, the counterweight block will be pushed in the direction of the center of gravity movement, thereby reducing the impact of the unbalanced force on the top caused by the extension of the scissor frame, and improving the overall stability of the lifting platform. The top limit block of the fixed plate prevents the ventilation equipment placed on the upper part from sliding and affecting the accuracy of the installation positioning.

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-4 As shown, a ventilation equipment installation lifting platform includes a support base 1, a scissor frame 2 and a hydraulic telescopic rod 3 are installed on the support base 1, a support top plate 5 is installed on the top of the scissor frame 2, the upper surface of the support top plate 5 is fixedly connected to a fixed plate 7, a counterweight block 11 is installed on the lower surface of the fixed plate 7, two bidirectional threaded rods 15 are installed in a "cross" shape inside the fixed plate 7, the two bidirectional threaded rods 15 are staggered up and down, and four limit blocks 8 are slidably installed on the upper surface of the fixed plate 7.

[0023] One end of the bottom of the scissors frame 2 is rotatably connected to the inner side surface of the support base 1, and one end of the top of the scissors frame 2 is rotatably connected to the inner side surface of the support top plate 5. The side surfaces of the support base 1 and the support top plate 5 are both provided with movable grooves 4. The other end of the bottom of the scissors frame 2 is slidably connected to the support base 1 through the movable groove 4, and the other end of the top of the scissors frame 2 is slidably connected to the support top plate 5 through the movable groove 4. When the scissors frame 2 is extended, the sliding end can move along the movable groove 4.

[0024] A movable block 10 is slidably installed on the outer side of the movable groove 4 supporting the top plate 5. The movable block 10 is rotatably connected to the scissor frame 2. A slide bar 6 is fixedly installed on the movable block 10. The other end of the slide bar 6 is fixedly connected to the counterweight block 11. A slide groove 14 is provided on the lower surface of the fixed plate 7. The counterweight block 11 is slidably connected to the fixed plate 7 through the slide groove 14. When the scissor frame 2 is extended, the movable block 10 moves to the left. At this time, the supporting center of gravity of the scissor frame 2 moves to the left, and the left side of the fixed plate 7 is easy to tilt up. The movable block 10 drives the slide bar 6 and the counterweight block 11 to move to the left at the same time, thereby adding weight to the left side of the fixed plate 7, thereby achieving the balance of the fixed plate 7 when the scissor frame 2 is active.

The two ends of the two bidirectional threaded rods 15 are both sleeved with sliders 16. The sliders 16 are threadedly connected to the bidirectional threaded rods 15. The sliders 16 are slidably connected to the inner surface of the fixed plate 7. Two servo motors 17 are fixedly installed on the outer surface of the fixed plate 7. The two bidirectional threaded rods 15 are respectively coaxially fixedly connected to the rotating shaft of a servo motor 17. The rotation of the bidirectional threaded rods 15 can be controlled by controlling the forward and reverse rotation of the servo motor 17, so as to drive the sliders 16 to move in opposite directions, thereby realizing the clamping of the ventilation equipment by the limit block 8.
