Use the torque to keep the vertical bridge construction with strong suction to stabilize the warning device

Abstract

The invention discloses a strong-suction stable warning device capable of keeping upright by using torque used for bridge construction. The strong-suction stable warning device structurally comprisesa warning board, an upright keeping mechanism, a fixing disc, a triangular supporting frame and a stabilizing device, wherein the warning board is installed on the top of the upright keeping mechanismand mechanically connected with the upright keeping mechanism, and the upright keeping mechanism is mechanically connected with the triangular supporting frame through the fixing disc. The strong-suction stable warning device has the advantages that by using the characteristic that the action point of the gravity center in a conical cavity is in the center of an iron layer all the time, the torque of the iron layer is larger than the torque of the end, connected with the warning board, of a U-shaped connecting rod all the time, so that it is achieved that the warning board keeps upright; thewarning device is sucked to the ground surface through a sucker, the holding force between the triangular supporting frame and the ground is increased, it is avoided that the warning board is collapsed under the action of external force, and the situation that after the warning board is collapsed, unwitting people enter a construction site by accident is avoided.

Description

technical field [0001] The invention relates to the field of warning signs, in particular to a strong suction stabilizing warning device for bridge construction which uses the magnitude of moment to keep it upright. Background technique [0002] During the construction of the bridge, it is necessary to carry out procedures such as measurement and lofting, base formwork construction, steel bar construction, and pouring. The construction period is relatively long. Since the construction of the bridge has not yet been completed, there are potential safety hazards. Therefore, non-workers are not allowed to enter during the construction process. Construction site, so need to set up safety warning signs on the construction site, the current warning signs for bridge construction have the following defects: [0003] At present, in order to prevent the warning signs from collapsing, most construction sites will place stones on the warning sign stands to increase the gravity of the wa...

[0002] During the construction of the bridge, it is necessary to carry out procedures such as measurement and lofting, bottom formwork construction, steel bar construction, and pouring. The construction period is long. Since the construction of the bridge has not yet been completed, there are potential safety hazards. Therefore, non-workers are not allowed to enter during the construction process. Construction site, so need to set up safety warning signs on the construction site, the current warning signs for bridge construction have the following defects:

[0003] At present, most construction sites will place stones on the warning sign frame to increase the gravity of the warning sign to prevent the warning sign from collapsing, and prevent the warning sign from collapsing under the action of external force. The surrounding environment of the bridge is relatively open, so the wind is strong. It is easy to blow off the warning sign, causing uninformed people to enter the construction site by mistake, posing a safety hazard
