Bridge hanging basket construction potential safety hazard monitoring system and control method

Abstract

The invention discloses a bridge hanging basket construction potential safety hazard monitoring system, which is applied to hanging basket equipment. The system comprises a sensing module, an action module, an alarm, a PLC electrical control module, a serial port server module, a switch, a router and a local handheld terminal; the sensing module, the action module and the alarm are electrically connected with the PLC electrical control module; the PLC electrical control module is further connected with a remote serial port module; the serial port server module is connected to the switch; the switch is connected to the router; and the local handheld terminal is connected with the router in a local area network. Each parameter value in a construction process of the hanging basket equipment is detected through the sensing module; and the PLC electrical control module is used for sending alarm information after each parameter value is compared with a preset value on one hand, and performing visual display at the local handheld terminal through the local area network and sending out a control command to carry out safety protection on the other hand, so that the monitoring of potential safety hazards of hanging basket construction is realized.

Description

technical field [0001] The invention relates to the field of bridge hanging baskets, in particular to a monitoring system and a control method for potential safety hazards in the construction of bridge hanging baskets. Background technique [0002] Bridge construction is an important part of road traffic construction. Regardless of the shape of the bridge or the construction environment, the hanging basket is one of the key equipment in bridge construction. The hanging basket is the main equipment in the cantilever construction. According to the structure, it can be divided into truss type, inclined There are 4 types of pull type, steel type and mixed type. The hanging basket is light in weight, simple in structure, strong and stable, easy to move forward and assemble and disassemble, has strong reusability, small deformation after stress, etc., and there is sufficient space under the hanging basket, which can provide a large construction work surface, which is beneficial to...

AI Technical Summary

Problems solved by technology

Hanging basket construction is often located on high-altitude bridge piers, which belongs to high-altitude operations, with a high degree of risk, and the risk factor of manual operation is high. There are many unsafe factors based on the experience of construction personnel; hanging basket construction is high-altitude operations, and the effect of crosswinds will have a negative impact on the system. Disturbance affects construction accuracy, and there is even a risk of overturning under strong winds. In practice, the impact of wind speed on the moving hanging basket equipment is enough to cause derailment or even overturning of the hanging basket equipment, and the positioning of the moving hanging basket equipment is difficult to accurately grasp; For hanging basket construction, the concrete pouring has strict temperature requirements to ensure the quality of the bridge. If the temperature is too low or too high, the quality of concrete pouring cannot be guaranteed, especially for the construction of the bridge section. Therefore, The ambient temperature of the actual construction needs to be monitored in real time; at the same time, the hanging basket equipment carries a large number of electrical equipment and many of them are strong electrical equipment, and there are fire hazards caused by excessive load during work.
