Problems solved by technology

Small fires can be extinguished with ordinary fire extinguishers, while large fires require fire trucks to spray water. At present, two firefighters are required to hold a high-pressure fire hose to spray water. High pressure makes the work of firefighters more difficult and increases the The number of personnel engaged in firefighting work

Abstract

A semi-automatic fire-fighting lance carrying rack with two degrees of freedom comprises a gear drive mechanism, a cam mechanism and a sheave drive mechanism, wherein the gear drive mechanism comprises three gears and three rotating shafts; the cam mechanism comprises a pulling buckle, a cam and a tappet; and the sheave drive mechanism comprises a first drive plate, a first straight pin, a second drive plate, a second straight pin, a sheave, a compression spring, a spline and a splined hub. The cam is driven to push the tappet so as to enable the spline at the upper end of the sheave to be jointed with the splined hub, a motor transmits power to the drive plates through the gear drive mechanism, the straight pins on the two drive plates drive the sheave to rotate, the two straight pins rotate in the opposite directions and have 180-degree phase difference, so that a splined hub upper mechanism is driven to swing back and forth in the range of 0-90 degrees, a lance is embedded to a lance bayonet which can rotate around a rotating shaft of the bayonet and is locked by a locking nut, and a height adjustment rod can be adjusted vertically and locked. The semi-automatic fire-fighting lance carrying rack can reduce the fire-fighting work intensity and reduce the number of staff for the fire-fighting work.

Description

technical field [0001] The invention relates to fire-fighting equipment for fire-fighting vehicles, in particular to a double-degree-of-freedom semi-automatic fire-fighting water gun carrying frame. Background technique [0002] Fires occur from time to time in residential areas, and forest fires are not uncommon, which pose a serious threat to people's lives and properties. Small fires can be extinguished with ordinary fire extinguishers, while large fires require fire trucks to spray water. At present, two firefighters are required to hold a high-pressure fire hose to spray water. High pressure makes the work of firefighters more difficult and increases the The number of personnel involved in firefighting efforts. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dual-degree-of-freedom semi-automatic fire-fighting water gun carrying frame, which can reduce the work difficulty of firefighters, reduce the number...
