Description

Technical Field

[0001] The utility model relates to the technical field of warning barriers, in particular to an anti-dumping warning barrier. Background Art

[0002] Warning barriers are used to remind and warn construction site personnel and passersby. Through eye-catching signs and warnings, warning barriers remind construction workers and passersby of potential safety risks, helping them to improve their safety awareness. By marking dangerous areas and construction activities, warning barriers reduce the probability of accidents, indicate appropriate routes and construction areas, ensure that passersby can safely bypass construction areas, and reduce the risk of traffic accidents.

[0003] Warning barriers help organize and manage construction sites, alert potential dangers, mark construction areas, prevent unauthorized entry, ensure construction site safety, and enhance safety awareness among the public and construction workers. Due to the complex construction environment, various equipment and materials are easily piled up on construction sites. At this time, it is necessary to raise the warning barriers to reduce the obstruction of the warning barriers by equipment and materials. When the warning barriers are raised, the center of gravity of the warning barriers themselves increases, making them susceptible to wind or external forces, increasing the possibility of tipping over. Therefore, we propose an anti-tipover warning barrier. Utility Model Content

[0004] The utility model aims to provide an anti-dumping warning bar to solve the problem that after the warning bar is raised, the center of gravity of the warning bar itself rises accordingly, which makes it easy to be affected by wind or external force, increasing the possibility of dumping.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-dumping warning fence, comprising a base frame and a railing, a railing is arranged on the upper side of the base frame, a connecting rod is fixed on the inner side of the railing, the connecting rod is slidably docked with a first sliding rod, the support rods on both sides of the base frame are slidably docked with a second sliding rod, and the second sliding rod is fixed to the railing, a fixing rod is fixed to the middle part of the railing, and a screw rod is docked on the lower side of the fixing rod, a first transmission assembly is arranged below the screw rod, and the first transmission assembly includes a synchronous wheel and a synchronous belt.

[0006] Preferably, the lower end of the screw rod is fixed to the synchronous wheel of the first transmission assembly, and the synchronous wheel of the first transmission assembly away from the screw rod is connected to the knob.

[0007] Preferably, the synchronous wheel and the knob of the first transmission assembly are movably connected to the base frame via bearings respectively.

[0008] Preferably, a second transmission assembly is arranged below the synchronous wheel of the first transmission assembly close to the screw, and the second transmission assembly includes five bevel gears, and the lower side of the synchronous wheel of the first transmission assembly close to the screw is fixed to the bevel gear of the second transmission assembly through a center rod.

[0009] Preferably, the lower sides of the bevel gears on both sides of the second transmission assembly are fixed to the toothed disc via a center rod, and the bevel gears and toothed disc of the second transmission assembly are movably connected to the base frame via bearings respectively.

[0010] Preferably, tooth plates are respectively connected to both sides of the toothed disc, and one end of the tooth plate is fixed to a support plate, and the support plate is slidably connected to a bottom plate on the lower side of the bottom frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when the height of the warning bar is adjusted, the electric wrench drives the knob to rotate, so that the knob can drive the screw rod and the bevel gear of the second transmission assembly to rotate through the first transmission assembly. When the screw rod rotates, the railing can be moved away from the base frame, so that the height of the warning bar can be adjusted, and at the same time, the gear disc can drive the two tooth plates to move in opposite directions, so that the tooth plate can push the support plate to slide along the inner side of the bottom plate of the base frame, so that the support plate can stably expand the support range of the warning bar, so that the warning bar can enhance stability and is not easy to tip over after being raised.
