This invention involves rotating a rotating plate, then pulling and rotating the second partition downwards, causing the second partition to fold. Pushing the first partition allows for easy movement and placement of the device. By unfolding the second partition, aligning the bottom end of the insert rod with the threaded hole and rotating it, then pulling each fixing plate outwards and pulling the support plate downwards, when the round-headed rod on the side of the support plate passes through the round opening on the side of the fixing plate, the first spring pushes against the round-headed rod and locks it between the inner walls of the round opening, thus fixing the support plate and supporting its bottom end on the ground, preventing it from tipping over due to adverse weather conditions. However, this method is cumbersome, requires customized parts, and is costly. Therefore, a mechanically connected anti-tipping device suitable for dynamic adjustment and modular assembly is needed.

[0023] By adjusting the shock absorption module 2, the angle of the rotatable guardrail 1 can be finely adjusted according to the slope of the working surface, so that the rotatable guardrail 1 is perpendicular to the working surface, which is suitable for different working surfaces. When an external force impacts, the shock absorption module 2 compresses and absorbs energy to prevent the rotatable guardrail 1 from structurally breaking.

[0024] Preferably, the rotatable guardrail 1 is made of circular steel pipe with a painted surface.

[0025] Furthermore, the anti-tipping connector 4 includes a connecting arm 41 and a limiting boss 42. One end of the connecting arm 41 is connected to the rotating mechanism 5, and the other end is provided with a limiting boss 42, which protrudes in the direction of the fixed support block 3.

[0026] Furthermore, the fixed support block 3 includes an installation part 31, a limiting part 32, and a limiting groove 33. The limiting groove 33 is disposed between the installation part 31 and the limiting part 32. The installation part 31 is connected to the rotating mechanism 5, and the limiting groove 33 is adapted to the limiting boss 42.

[0027] Furthermore, the rotatable guardrail 1 is fixedly connected to the rotating mechanism 5, and the rotating mechanism 5 and the fixed support block 3 are rotatably connected by fasteners 6, with wear-resistant buffers installed at the connection.

[0028] The clamping angle and position of the fixed support block 3 and the rotating mechanism 5 are dynamically adjusted by fastener 6 to accommodate shafts of different diameters. Wear-resistant buffer components reduce the transmission of vibration.

[0029] Preferably, the connection between the fixed support block 3 and the rotating mechanism 5 is a double-clamping arm structure, and the fastener 6 is a hexagonal bolt. The rotating mechanism 5 is clamped by the hexagonal bolt, and wear-resistant pads are installed on the clamping surfaces. The hexagonal bolts are designed to prevent loosening and support quick adjustment of tightness.

[0030] Furthermore, the shock absorption module 2 is a buffer spring, a silicone damping block, or a hydraulic buffer.

[0031] Furthermore, the shock absorption module 2 is replaced with anchor bolts.

[0032] Furthermore, the anti-tipping connector 4 and the rotating mechanism 5 are rotatably connected via fasteners 6, and a wear-resistant buffer is installed at the connection point. The clamping angle and position of the anti-tipping connector 4 and the rotating mechanism 5 can be dynamically adjusted via fasteners 6 to accommodate shafts of different diameters. The wear-resistant buffer reduces the transmission of vibration.

[0033] Preferably, the connection between the anti-tipping connector 4 and the rotating mechanism 5 is a double-clamping arm structure, and the fastener 6 is a hexagonal bolt. The rotating mechanism is clamped by the hexagonal bolt, and wear-resistant gaskets are installed on the clamping surfaces. The hexagonal bolts are designed to prevent loosening and support quick adjustment of tightness.

[0034] Furthermore, the rotating mechanism 5 has a zigzag structure, including a turning part 51, a rotating part 52, and a fixed connection part 53. The turning part 51 is disposed between the rotating part 52 and the fixed connection part 53. The anti-tipping connector 4 is connected to the turning part 51, the fixed support block 3 is connected to the rotating part 52, and the rotatable guardrail 1 is connected to the fixed connection part 53. The fixed support block 3 and the rotatable guardrail 1 are disposed on both sides of the rotating mechanism 5.

[0035] Furthermore, a tilt sensor is installed on the top of the rotatable guardrail 1. The tilt status of the rotatable guardrail 1 can be monitored in real time by the tilt sensor.

[0036] Preferably, the fastener 6 is a hexagonal bolt.

[0037] Furthermore, the rotatable guardrail 1 is equipped with standardized slots, through which lateral support mechanisms or diagonal support structures can be added. The slots allow for the rapid addition of extended lateral or diagonal support structures, such as lateral support rods or stay cables, improving overall stability. The standardized slot structure also enables the quick connection of additional functional modules, such as sensors and shock absorbers. Lateral support mechanisms include lateral support rods, and diagonal support structures include stay cables.

[0038] The modular adjustable mechanical connection guardrail anti-tipping device of this embodiment 1 can be used on underground scrapers. During installation, the fixed support block 3 is first installed and fixed on the plane of the underground scraper. Then, the rotatable guardrail 1 is installed on the fixed support block 3 through the rotating mechanism 5 and connected by fasteners 6. Wear-resistant buffers are installed on the clamping surface. Next, the shock absorption module 2 is adjusted so that the rotatable guardrail 1 is perpendicular to the working surface. Then, the anti-tipping connector 4 is installed on the rotating mechanism 5 and connected by fasteners 6. Wear-resistant buffers are installed on the clamping surface. Finally, according to the actual working requirements, a horizontal support rod or a diagonal cable is added to the rotatable guardrail 1 through a standardized slot to improve the overall stability. When the modular adjustable mechanical connection guardrail anti-tipping device of this embodiment 1 is not in operation, the rotatable guardrail 1 is set on the upper side of the fixed support block 3 and is set parallel to the fixed support block 3. At this time, the anti-tipping connector 4 is set between the rotatable guardrail 1 and the fixed support block 3, the connecting arm 41 is located above the limiting part 32, the limiting boss 42 is located outside the limiting groove 33, and the anti-tipping connector 4 is in the released state. During operation, the rotatable guardrail 1 is first rotated so that the shock-absorbing module 2 comes into contact with the working surface. The shock-absorbing module 2 can finely adjust the angle of the rotatable guardrail according to the slope of the working surface, so that the rotatable guardrail 1 is perpendicular to the working surface. When the rotatable guardrail 1 rotates counterclockwise, it drives the rotating mechanism 5 to rotate counterclockwise around the fastener 6 connecting the rotating mechanism 5 and the fixed support block 3, and drives the anti-tipping connector 4 to rotate around the fastener 6 connecting the rotating mechanism 5 and the fixed support block 3. At the same time, the anti-tipping connector 4 droops under its own weight during the rotation, so that the limiting boss 42 is engaged in the limiting groove 33, locking the anti-tipping connector 4 and the rotating mechanism 5, preventing the rotating mechanism 5 from rotating clockwise, thereby limiting the rotatable guardrail 1 and preventing the rotatable guardrail 1 from tipping over.
