Problems solved by technology

At present, the pitching and slewing mechanism of the common fire monitor generally adopts an independent worm gear mechanism, and the spray angle of the fire monitor muzzle is changed by its rotation to achieve spraying. Therefore, at least three elbows are set in the conventional fire monitor structure, which will affect the fire protection. The hydraulic characteristics of the internal flow path of the fire monitor affect the spray performance of the fire monitor, and increase the volume and weight of the fire monitor

Abstract

The invention belongs to the technical field of fire fighting apparatuses and in particular relates to a pitching slewing mechanism linked with horizontal slewing for a fire monitor. The pitching slewing mechanism is composed of a gun support, a lower bending pipe, an upper bending pipe, a horizontal slewing worm gear, a horizontal slewing worm, a pitching slewing worm gear and a pitching slewing worm. According to the pitching slewing mechanism linked with horizontal slewing for the fire monitor, a structure that the horizontal slewing of the fire monitor is linked with the pitching slewing is adopted to realize pitching slewing of the fire monitor, a phenomenon that the existing fire monitor realizes pitching slewing by utilizing the pitching slewing worm gear and the pitching slewing worm independently is changed, the quantity of elbows of the fire monitor is reduced, the hydraulic characteristic of an internal flow passage of the fire monitor is optimized, the injection performance of the fire monitor is improved and the structure of the fire monitor is relatively compact.

Description

technical field [0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to a fire monitor pitching and turning mechanism linked with horizontal turning. Background technique [0002] The pitch and slewing mechanism of the fire monitor is a key component in the structure of the fire monitor, which mainly realizes the spraying of the fire monitor at different pitch angles. At present, the pitching and slewing mechanism of the common fire monitor generally adopts an independent worm gear mechanism, and the spray angle of the fire monitor muzzle is changed by its rotation to achieve spraying. Therefore, at least three elbows are set in the conventional fire monitor structure, which will affect the fire protection. The hydraulic characteristics of the internal flow path of the fire monitor affect the spray performance of the fire monitor, and increase the volume and weight of the fire monitor. Contents of the invention [0003]...
