[0002] A safety net is a specified safety protection facility in a helicopter apron. The existing safety protection nets used around the apron are located around the apron and suspended in the air. Therefore, the use of stainless steel materials for traditional safety protection nets will cause the overall weight to be relatively heavy, and in a suspended state, there is an easy safety hazard of the safety net falling by itself. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a lifting safety protection net, which solves the problem that the use of stainless steel materials for traditional safety protection nets will cause the overall weight to be relatively heavy, and in a suspended state, there is an easy safety hazard of the safety net falling by itself.

[0004] To achieve the above object, the utility model is realized through the following technical solutions: A lifting safety protection net, including a base, the top of the base is movably connected with a column through a column connecting piece, reinforcing pieces are fixedly installed on the opposite sides of the column, and a connecting rod is movably connected to the top of the base. A guiding member is fixedly installed on the surface of the column, one end of the connecting rod is slidably sleeved on the guiding member, and an electric push rod is rotatably connected between the surface of the top of the base and the reinforcing piece.

[0005] Preferably, armrests are symmetrically and fixedly connected to the inner cavity of the column.

[0006] Preferably, a mesh is arranged between the armrests.

[0007] Preferably, a U-shaped frame is fixedly installed at the top of the column.

[0008] Preferably, the electric push rod is located on the side of the reinforcing piece and the base.

[0009] Preferably, both sides of the mesh are located in the inner cavity of the column.

[0010] The utility model provides a lifting safety protection net. Compared with the prior art, it has the following beneficial effects:

[0011] 1. When the electric push rod extends, the lifting safety protection net drives the upright column to rotate upward on the base through the column connecting piece due to the connection of the reinforcing piece. At the same time, it drives the connecting rod to slide in the inner cavity of the guiding piece through the guiding piece and also rotates on the base until the connecting rod slides to the limit stroke on the guiding piece, causing the upright column to drive the mesh to rotate 180 degrees from the air to 90 degrees vertically, making it stand up. When needed, the upright column can drive the handrail to reset through the above steps, thus realizing the automatic lifting function, avoiding the long-term suspended state, and effectively reducing the safety hazard of the self-falling of the safety net.

[0012] 2. The lifting safety protection net is made of aluminum alloy material, making the overall weight of the whole net lighter and reducing the weight. Secondly, the overall structure is safe, practical, beautiful and corrosion-resistant. Among them, the aluminum alloy electric push rod is small in volume, light in weight, convenient for installation and debugging, and is equipped with overload protection and stroke control mechanisms, which is convenient for realizing automatic control.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: a lifting safety protection net, including a base 1. The top of the base 1 is movably connected with a column 6 through a column connecting piece 2. Symmetrically fixed inside the column 6 are handrails 4. Between the handrails 4 is arranged a mesh sheet 5. Both sides of the mesh sheet 5 are located inside the column 6. The top of the column 6 is fixedly installed with a U-shaped frame 10. Reinforcing pieces 3 are fixedly installed on the opposite sides of the column 6. And the top of the base 1 is movably connected with a connecting rod 8. And a guiding member 7 is fixedly installed on the surface of the column 6. One end of the connecting rod 8 is slidably sleeved on the guiding member 7. There is a rotational connection between the top of the base 1 and the surface of the reinforcing piece 3 for an electric push rod 9. The electric push rod 9 is located on the side of the reinforcing piece 3 and the base 1. Among them, the shapes of the left and right bases 1 are different at multiple parts connected to the electric push rod 9, and the electric push rod 9 can be installed on either the left or the right side. This device is made of aluminum alloy material, making the overall weight of the whole net relatively light, reducing the weight. Among them, the aluminum alloy electric push rod 9 is small in volume, light in weight, and convenient for installation and debugging. It is equipped with an overload protection and a stroke control mechanism, facilitating automatic control. The guiding member 7 can effectively control the movement direction of the safety net to be consistent with the working angle.

[0019] During specific use, first install the base 1 around the apron and arrange and install the device so that its plane is suspended in the air. When it is necessary to retract, start the electric push rod 9. When the electric push rod 9 extends, due to the connection of the reinforcing piece 3, it drives the column 6 to rotate upward on the base 1 through the column connecting piece 2. At the same time, it drives the connecting rod 8 to slide inside the guiding member 7 through the guiding member 7 and also rotate on the base 1 until the connecting rod 8 slides to the limit stroke on the guiding member 7, causing the column 6 to drive the mesh sheet 5 to rotate 180 degrees from the air to a vertical 90 degrees, making it stand up. When needed, the column 6 can be driven to drive the handrail 4 to reset through the above steps, thus realizing the automatic lifting function, avoiding the long-term suspended state, and effectively reducing the safety hazard of the self-falling of the safety net.

[0020] And the aluminum alloy electric push rod safety net of this device is simple and convenient to install, light in itself and has a large load-bearing capacity. It has the debugging of the automatic lifting function and is suitable for the use of safety nets at various working angles. The aluminum alloy electric push rod safety net has the characteristics of safe overall structure, practical and beautiful appearance, and corrosion resistance.
