[0002] Steel structure grid is a network structure composed of steel materials, which has the advantages of light weight, large span, material saving and fast construction speed. After being covered with shielding materials, it can be widely used in the construction of some shed areas, such as rain and sun shading equipment in squares.

[0022] The implementation method of the anti-dumping steel structure grid assembly comprises the following steps:

[0023] Step 1: Steel structure grid assembly

[0024] The bottom plate is fixed to the bottom of the hollow sliding column, the lifting sliding column is installed in the upper end of the hollow sliding column, the fixed cross plate is installed between the hollow sliding columns, the fixed cross frame is installed between the lifting sliding columns, the threaded sleeve and the second motor are installed on the fixed cross plate, the transmission gear is fixedly connected to the position of the upper end of the threaded sleeve, the output end of the second motor is installed with a motor gear, the motor gear is meshed with the transmission gear, the first threaded rod is cooperatively installed in the threaded sleeve, the top of the first threaded rod is fixed to the bottom surface of the fixed cross frame, an intermediate ceiling is installed on the top of the lifting sliding column, a side beam is installed on the side of the lifting sliding column in the area below the intermediate ceiling, an electric cylinder and a rotating hinge are installed on the side beam, one end of the electric cylinder is hinged to the lifting block, and the other end is hinged to the driving arm, and a wind sensor is installed on the top of the intermediate ceiling;

[0025] A first fixing bar is installed on the driving arm and the rotating hinge, a second fixing frame is installed on the first fixing bar, a third fixing bar is installed on a side of the second fixing frame away from the first fixing bar, a second grid is installed in the second fixing frame, a second threaded rod and a sliding rod are installed between the first fixing bar and the third fixing bar, a first motor is installed on the first fixing bar, an output end of the first motor is connected to the second threaded rod, the second fixing bar is slidably connected between the two sliding rods, the second threaded rod is threadedly connected to the second fixing bar, a first fixing frame is installed on one side of the second fixing bar, a first grid is installed in the first fixing frame, and the second grid and the first grid are both covered with a cover plate;

[0026] Step 2: Fix components and adjust uplink

[0027] Install expansion bolts in the installation holes and fix them on the ground. The second motor drives the threaded sleeve to rotate through the motor gear and the transmission gear, driving the first threaded rod, the fixed cross frame, and the lifting slide column to move upward to the set height.

[0028] Step 3: Expand and extend

[0029] The locking hole and the locking pin are separated. After separation, the electric cylinder is started, and the output end of the electric cylinder is retracted. At the same time, the lifting block on the side away from the lifting slide column is driven upward, and the lifting block on the side close to the lifting slide column is driven downward through the gear body. The anti-retraction elastic tooth part on the side away from the lifting slide column is adapted to the tooth surface at the top of the moving groove, ensuring that the sliding body moves unidirectionally along the moving groove toward the side away from the lifting slide column, and at the same time, it will also drive the sliding body to move. While moving, the moving rod will also move toward the side away from the moving groove, exposing the elastic clamp head. As the output end of the electric cylinder continues to retract, the side wall of the first fixing bar will squeeze the elastic clamp head until it enters the limiting hole, releasing the force at the end of the electric cylinder. It is only necessary to provide a force to ensure the adaptation of the anti-retraction elastic tooth part and the tooth surface.

[0030] The first motor drives the first threaded rod to rotate, and the second fixing bar drives the first fixing frame to expand outward to form a larger shielding area;

[0031] Step 4: Adjust downwards and fold for storage

[0032] When the wind force sensor detects that the wind force exceeds the set tolerance threshold, the second motor drives the threaded sleeve to rotate through the motor gear and the transmission gear, driving the first threaded rod, the fixed horizontal frame, and the lifting slide column to move downward to the set height;

[0033] The first motor drives the first threaded rod to rotate in the opposite direction, and the second fixing bar drives the first fixing frame to retract;

[0034] The electric cylinder starts to extend the output end again, first driving the lifting block on the side away from the lifting slide column downward, and driving the lifting block on the side close to the lifting slide column upward through the gear body, the anti-retraction elastic tooth part and the tooth surface on the side away from the lifting slide column are separated, and the lifting block and the tooth surface on the side close to the lifting slide column are adapted. As the electric cylinder drives the sliding body to move toward the side close to the lifting slide column, it also drives the moving rod to move toward the side close to the lifting slide column until the elastic clamp and the limiting hole are separated. After separation, as the output end of the electric cylinder continues to extend, the first fixing bar is rotated downward until the locking hole and the locking pin are matched.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The present invention can detect the wind force when in use by setting up a wind sensor. When the wind force is strong, the second grid and the first grid can be folded by the lifting assembly, the moving assembly and the folding assembly, thereby reducing the influence of the wind force. At the same time, after folding, the locking pin can be inserted into the locking hole for locking, thereby further improving the strength, increasing the wind resistance and avoiding tipping damage in windy weather.

[0037] 2. The present invention releases the output end force of the electric cylinder by setting a lifting block, a sliding body, and a moving part, thereby ensuring the long-term stability of the component structure, and utilizes an elastic clamp and an anti-retraction elastic tooth part to selectively adjust the position of the electric cylinder and freely switch the fixed and unlocked states of the first fixing bar to achieve a stable and reliable structure.

[0061] The implementation method of the anti-dumping steel structure grid assembly comprises the following steps:

[0062] Step 1: Steel structure grid assembly

[0065] Step 2: Fix components and adjust uplink

[0066] Install the expansion bolts in the mounting hole 5 and fix them on the ground. The second motor 21 drives the threaded sleeve 23 to rotate through the motor gear 20 and the transmission gear 22, driving the first threaded rod 19, the fixed cross frame 16, and the lifting slide column 2 to move upward to the set height.

[0067] Step 3: Expand and extend

[0068] The locking hole 4 and the locking pin 6 are separated. After the separation, the electric cylinder 12 is started, and the output end of the electric cylinder 12 is retracted. At the same time, the lifting block 175 away from the lifting slide post 2 is driven upward, and the lifting block 175 close to the lifting slide post 2 is driven downward through the gear body. The anti-retraction elastic tooth piece 176 on the side away from the lifting slide post 2 is adapted to the tooth surface at the top of the moving groove 171, ensuring that the sliding body 172 moves unidirectionally along the moving groove 171 away from the lifting slide post 2, and at the same time, it will also drive the sliding body 172 to move. While moving, the moving rod 1731 will move to the side away from the moving groove 171, exposing the elastic clamp head 1732.

[0072] The first motor 15 drives the first threaded rod 19 to rotate in the opposite direction, and the second fixing bar 26 drives the first fixing frame 7 to retract;

[0073] The electric cylinder 12 starts to extend the output end again, first driving the lifting block 175 on the side away from the lifting slide 2 downward, and driving the lifting block 175 on the side close to the lifting slide 2 upward through the gear body, and the anti-retraction elastic tooth part 176 on the side away from the lifting slide 2 is separated from the tooth surface, and the lifting block 175 on the side close to the lifting slide 2 is adapted to the tooth surface. As the electric cylinder 12 drives the sliding body 172 to move toward the side close to the lifting slide 2, it also drives the moving rod 1731 to move toward the side close to the lifting slide 2 until the elastic clamp 1732 and the limiting hole 241 are separated. After separation, as the output end of the electric cylinder 12 continues to extend, the first fixing bar 24 is rotated downward until the locking hole 4 and the locking pin 6 are matched.
