Automatic sand throwing fire extinguishing device and articulated vehicle

Abstract

The invention provides an automatic sand throwing fire extinguishing device and an articulated vehicle. The articulated vehicle, an auxiliary frame, a power system, a hydraulic system, a sandbox assembly and a throwing system are included, wherein the auxiliary frame, the power system, the hydraulic system, the sandbox assembly and the throwing system are arranged on the articulated vehicle. A fire extinguishing agent can be quickly and continuously thrown to a fire area at a long distance, the throwing amount is large, the throwing distance is long, high-efficiency fighting can be achieved, and the fighting efficiency and safety of a fire disaster of dangerous chemicals avoiding water are improved; the power of the independent sand throwing fire extinguishing device is independent, and therefore more play is given to power performance; walking while working can be achieved, the fire extinguishing angle can be adjusted in time, and the needs for high-efficiency and safe fire extinguishing of special fires in various ranges are met; and the articulated vehicle can be mounted on all kinds of traction main vehicles, the demand for mounting the articulated vehicle on more vehicles in enterprises and institutions is met, and the vehicle utilization rate is improved.

Description

technical field

[0001] The invention relates to the field of emergency rescue, in particular to an independently powered sand throwing fire extinguishing device and a trailer. Background technique

[0002] In recent years, with the increasing number and scale of enterprises related to flammable and explosive dangerous goods in our country, it has caused a large number of casualties, property losses and environmental pollution, bringing immeasurable losses to the society. According to the guiding opinions of the State Council on fire protection work, large enterprises and institutions such as large oil fields, ports, chemicals, and electric power companies with high fire hazards are required to establish full-time enterprise fire brigades to be responsible for fighting special fires in their own enterprises. At present, when a special fire, especially a solid hazardous chemical fire that avoids water, cannot be extinguished with water, foam, or carbon dioxide, dry powder or s...

Examples

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0037] combine figure 1 and figure 2 , an automatic sand throwing fire extinguishing device of the present invention includes a sandbox assembly 6 and a throwing system 7; the sandbox assembly 6 includes a cargo box 601 for storing sand, which is arranged at the bottom of the cargo box to deliver sand to the feeding twister. The feeding bottom plate 602 of the dragon 603 and the feeding auger 603 that sand material is twisted into the throwing system; the throwing system 7 includes a rotatable throwing impeller 702 that throws sand material outward; All are driven to rotate by hydraulic motors; the feeding bottom plate 602 is driven to reciprocate by the expansion and contraction of hydraulic...
