Description

Operation and emergency rescue device for limited space of tank equipment

Technical Field

The utility model relates to a restricted space operation technical field specifically is a jar body equipment restricted space operation and emergency rescue device.

Background

The operations of closed and semi-closed equipment and places such as furnaces, towers, kettles, tanks, tank wagons, pipelines, sewers, ditches, pits, wells, pools and the like are generally called confined space operations. The operation in limited space is very frequent in the maintenance process of chemical production devices such as biological fermentation, and hazardous substances such as poisonous, harmful, inflammable and explosive substances can remain in the limited space, and fire, explosion, poisoning and suffocation accidents occur in the production and maintenance. In addition, some devices are internally provided with various transmission devices and electrical appliance lighting systems, and if the power supply is not completely separated and cut off before overhauling, or because of the misoperation of an electrical system, accidents such as mechanical injury, electric shock and the like can occur. Therefore, special safety management must be carried out on the operation of entering the limited space, and accidents are avoided from the source as much as possible. Meanwhile, a more perfect safety operation protection device is continuously provided for operators in a limited space, so that the operators, tools and the like can safely and smoothly enter the device in the operation process, and the obstacles of collision or incapability of construction are avoided.

The disease is prevented in advance, and the disease is caught in the future. Accidents can not be avoided by 100 percent, so that the safety protection and emergency handling capacity of the staff in limited space operation is improved, and the safety production consciousness and the self-rescue, escape and risk avoidance capacity of the staff are enhanced. The operating personnel and the team personnel need to be organized in due time to carry out special emergency drilling, and the emergency rescue device is suitable for the operation of the limited space of the tank body equipment.

Because the limited space of the tank body equipment has no tying point and the space is narrow, the single high-altitude falling prevention safety measure, such as the use of a falling protector, is relatively difficult, and if a safety accident occurs, the rapid and effective rescue can not be carried out. With the progress of science and technology, although some limited space operation and emergency rescue devices appear in the market, for example, the development of a tripod fills the blank of falling protection and emergency rescue protection in high-altitude operation. But the tripod is only suitable for the operation and rescue in the flat and open limited space above the kiln well and the like, and has poor actual pertinence with the chemical production such as biological fermentation and the like. Because the manhole at the top end of the tank body equipment is relatively small and no proper space is provided for erecting a tripod, a gap exists in the limited space operation and rescue device of the tank body equipment.
