Pulling device of foam fire extinguishing device

Abstract

The invention discloses a pulling device of a foam fire extinguishing device in the technical field of fire extinguishing equipment, the pulling device comprises a cart and a foam fire extinguishing device body, a push rod is welded to one end of the top of the cart, a wire winding mechanism with a self-locking function is installed on the push rod, a rope is wound on the wire winding mechanism, a universal wheel and a directional wheel mechanism are installed at the two ends of the bottom of the trolley respectively, and the end, away from the winding mechanism, of the rope is connected with a snapping mechanism for fixing the directional wheel mechanism. A rope is released or stored through the winding mechanism, so that an outer spline body on the clamping mechanism is engaged with or disengaged from an outer spline wheel in the directional wheel mechanism, meanwhile, a fixing block is driven to rotate to abut against and disengage from the ground, and therefore the directional wheel is rapidly fixed and disengaged.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing equipment, in particular to a pulling device of a foam fire extinguishing device. Background technique [0002] The foam fire extinguishing device is mainly composed of a foam liquid storage tank, a spray gun, a proportional mixer, a hose, and a trolley chassis. It is a new type of environmentally friendly and efficient foam fire extinguishing device. It is easy to operate, flexible and reliable. . In the initial stage of a fire, the device can be driven flexibly to the fire scene for fire extinguishing. This device can be used independently as a fire protection equipment, and can also be used as an auxiliary remedy in conjunction with a large fixed foam fire extinguishing system. [0003] When extinguishing the fire, the pipe joints at both ends of the pipeline proportional mixer are connected to the fire hose, and connected to the pressure water source. When water with a pressure of...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a pulling device for a foam fire extinguishing device to solve the problem that the bottom of the general trolley proposed in the above background technology can be fixed by using wheels with self-locking functions, but it requires the staff to squat down one by one. The wheels are locked, and they need to be opened one by one when they need to move, which is not conducive to the problem of fast movement and fixation in the case of fire fighting.
