Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse inner film installation, in particular to a greenhouse inner film installation platform. Background Art

[0002] Greenhouse lining generally refers to the technology of covering the interior of a greenhouse or greenhouse with a thin film. This technology creates an air layer between the inner and outer layers of greenhouse film, utilizing the heat-insulating effect of this air layer to raise the temperature inside the greenhouse, thereby maintaining a healthy growth environment for crops.

[0003] Greenhouse lining installation platforms are usually installed in greenhouses to assist workers in installing lining films in the greenhouse. Greenhouse lining installation platforms usually include guide rails and an operating platform. The rollers on the top of the operating platform are compatible with the guide rails. When the greenhouse lining film needs to be installed, the workers need to align the rollers on the top of the operating platform with the guide rails. After it is placed stably, the workers can then board the operating platform by themselves. However, at this time the operating platform is suspended in mid-air. When the workers board the operating platform, the operating platform is unstable and easily tilts to one side, which makes it difficult for the workers to board the operating platform alone.

[0004] Therefore, it is necessary to provide a new greenhouse inner film installation platform to solve the above technical problems. Utility Model Content

Support devices are provided at the four top corners of the bottom of the operating platform.

[0007] The supporting device includes a fixed seat and a telescopic rod, the telescopic rod is slidably arranged in the fixed seat, the fixed seat is fixedly connected to the bottom of the operating platform, a pair of mounting plates are fixedly arranged at one end of the fixed seat away from the operating platform, a rotating rod is arranged between the pair of mounting plates, a limiting device is rotatably connected to the rotating rod, a pressing groove is provided at the end of the fixed seat away from the operating platform, a first limiting groove and a second limiting groove are respectively provided at both ends of the telescopic rod, and the end of the limiting device can be extended into the first limiting groove and the second limiting groove.

[0008] Preferably, the limiting device includes a pressing plate and a spring, one end of the pressing plate is fixedly connected to the limiting column, the other end of the pressing plate is fixedly connected to the connecting plate, the bottom end of the connecting plate is fixedly connected to the spring, the other end of the spring is fixedly connected to the bottom of the pressing groove, and the limiting column can extend into the first limiting groove and the second limiting groove.

[0009] Preferably, when the spring is in a naturally extended state, the limiting column extends into the first limiting groove or the second limiting groove.

[0010] Preferably, when the limiting column extends into the first limiting groove, the telescopic rod is retracted into the fixing seat; when the limiting column extends into the second limiting groove, the telescopic rod extends out of the fixing seat and plays a supporting role.

[0011] Preferably, a same cross bar is welded to the inner sides of the top ends of the two brackets to make the operating platform more stable.

[0018] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0019] Please refer to Figures 1-4 ,in, Figure 1This is a structural diagram of a greenhouse inner film installation platform provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of the supporting device shown; Figure 3 for Figure 2 Another state diagram of the supporting device shown; Figure 4 for Figure 3 An enlarged view of point A is shown.

[0020] In the specific implementation process, Figures 1-4 As shown, a greenhouse inner film installation platform includes a guide rail 1 and an operating platform 5. The two ends of the guide rail 1 are fixedly connected to the two ends of the greenhouse shed 8. Brackets 3 are provided on both sides of the top of the operating platform 5. The tops of the two brackets 3 are each provided with a roller 2. The roller 2 can slide on the guide rail 1, thereby driving the operating platform 5 to move on the guide rail 1, making it convenient for workers to install the inner film in the entire greenhouse shed 8. Support devices are provided at the four top corners of the bottom of the operating platform 5.

[0021] The supporting device includes a fixed seat 6 and a telescopic rod 7. The telescopic rod 7 is slidably arranged in the fixed seat 6. The fixed seat 6 is fixedly connected to the bottom of the operating platform 5. A pair of mounting plates 14 are fixedly arranged at the end of the fixed seat 6 away from the operating platform 5. A rotating rod 15 is arranged between the pair of mounting plates 14. The rotating rod 15 is rotatably connected to a limiting device. A pressing groove 17 is provided at the end of the fixed seat 6 away from the operating platform 5. A first limiting groove 9 and a second limiting groove 10 are respectively provided at both ends of the telescopic rod 7. The end of the limiting device can be extended into the first limiting groove 9 and the second limiting groove 10.

[0022] The limiting device includes a pressing plate 11 and a spring 16. One end of the pressing plate 11 is fixedly connected to the limiting column 13, and the other end of the pressing plate 11 is fixedly connected to the connecting plate 12. The bottom end of the connecting plate 12 is fixedly connected to the spring 16. The other end of the spring 16 is fixedly connected to the bottom of the pressing groove 17. The limiting column 13 can extend into the first limiting groove 9 and the second limiting groove 10. Before the staff installs the greenhouse inner film, they press the pressing plate 11 downward away from one end of the telescopic rod 7. The connecting plate 12 and the spring 16 are squeezed by the pressing plate 11 and move into the pressing groove 17, driving the limiting column 13 at the other end of the pressing plate 11 to leave the second limiting groove 10 and pull the telescopic rod 7 out of the fixed seat 6 so that the telescopic rod 7 is against the bottom of the greenhouse shed 8. At this time, the pressing plate 11 is released to allow the limiting column 13 to extend into the first limiting groove 9, thereby supporting the operating platform 5.

[0023] When the spring 16 is in a naturally extended state, the limiting column 13 extends into the first limiting groove 9 or the second limiting groove 10 , thereby limiting the telescopic rod 7 and supporting the operating platform 5 .

[0024] When the limiting column 13 extends into the first limiting groove 9, the telescopic rod 7 is retracted into the fixing seat 6. When the limiting column 13 extends into the second limiting groove 10, the telescopic rod 7 extends out of the fixing seat 6 and plays a supporting role.

[0025] The same crossbar 4 is welded to the inner sides of the top ends of the two brackets 3 to make the operating platform 5 more stable.

[0026] The working principle provided by the present invention is as follows: the greenhouse inner film installation platform is installed in the greenhouse shed 8. Before the staff installs the greenhouse inner film, they press the pressing plate 11 downward away from one end of the telescopic rod 7. The connecting plate 12 and the spring 16 are squeezed by the pressing plate 11 and move into the pressing groove 17, driving the limiting column 13 at the other end of the pressing plate 11 to leave the second limiting groove 10, and pull the telescopic rod 7 out of the fixed seat 6, so that the telescopic rod 7 is against the bottom of the greenhouse shed 8. At this time, the pressing plate 11 is released to allow the limiting column 13 to extend into the first limiting groove 9, thereby supporting the operating platform 5. After that, the staff can board the operating platform 5, and can hold the guide rail 1 and pull it backward to drive the operating platform 5 to slide forward, so that the inner film of the greenhouse shed 8 can be installed.
