Description

Technical Field

[0001] This utility model relates to a protective device, and more particularly to a movable steel space frame construction protective device, belonging to the field of safety protection technology. Background Technology

[0002] High-altitude assembly, a common installation method for steel space frames, has been widely used in engineering projects in recent years. This method involves initially hoisting the space frame in sections and blocks, forming a stable structural unit after the initial span is completed. The remaining space frames are then assembled into small triangular units on the ground and installed using the high-altitude assembly method. This method is used along the length of the coal shed, employing small units for high-altitude assembly. However, this method requires workers to constantly move and assemble at high altitudes, resulting in long working hours and high risks. Traditional safety measures typically involve wearing safety harnesses at height. However, due to the rapid assembly of small units, workers need to move frequently, leading to frequent unhooking and retraction of safety harnesses. Double-hook safety harnesses may require the use of only one hook, and frequent retraction increases the risk of operational errors, reducing the safety factor. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a movable steel grid construction protection device that can protect personnel falling from heights when the safety belt loses its protective function, ensuring the safety of construction, and is convenient to use and easy to operate.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A movable steel space frame construction protection device includes a U-shaped bracket, a pole, and a safety air cushion. There are two U-shaped brackets, and a pole is set between the bottoms of the two U-shaped brackets. The safety air cushion is set on the U-shaped bracket, and a first buffer elastic net is set at the bottom of the safety air cushion. An outer bracket is set outside the safety air cushion, and a second buffer elastic net is set on the outer bracket. Rollers are set at the bottom of the U-shaped bracket and the outer bracket respectively.

[0006] A baffle is provided on the outer side of the top of the U-shaped bracket, and sleeves are respectively provided at the bottom of both ends of the U-shaped bracket. The insertion rod passes through the sleeves at the bottom of the two U-shaped brackets and is fixed by bolts.

[0007] The outer side of the U-shaped bracket is provided with a first end plate, and the end of the outer bracket is provided with a second end plate, and the first end plate and the second end plate are fixedly connected together by bolts.

[0008] There are four outer supports, and a second buffer elastic net is provided between adjacent outer supports.

[0009] Limit bolts are provided on the bracket on the side of the roller.

[0010] The first buffer elastic net is located between the tops of the two U-shaped supports.

[0011] The positive and beneficial effects of this utility model are:

[0012] 1. This utility model facilitates the movement of the device by setting rollers at the bottom of the U-shaped bracket and the outer bracket, and locks and fixes it by setting limit bolts on the bracket outside the rollers, thus ensuring safety and stability during use.

[0013] 2. This utility model can move with the construction personnel and can protect people falling from heights when the safety belt loses its protective function. It is convenient to use and easy to operate.

[0014] 3. This utility model avoids damage to the safety air cushion during movement by placing the safety air cushion between two U-shaped supports and ensuring that it does not directly contact the ground.

[0015] 4. This utility model is equipped with multiple safety protection measures. After personnel come into contact with the safety air cushion, the lower air cushion plays a buffering role. The first buffer elastic net can play a secondary buffering role when the air cushion is not fully inflated. The second buffer elastic net around the perimeter also prevents personnel from bouncing back and falling to the ground, thus improving the overall safety factor. Attached Figure Description
