Problems solved by technology

The structure of existing automatic fire monitor such as figure 1 As shown, including the cannon body, support, cannon body horizontal rotary drive mechanism and cannon body pitch rotary drive mechanism, the two sets of rotary drive mechanisms are both worm and worm gear transmission pairs, and are installed in series on the cannon body, so there are the following problems: 1. The cannon body is a cantilever beam structure with large volume, high center of gravity and low rigidity. It is affected by the recoil force of liquid spray during fire extinguishing, resulting in large overall deformation, which will not only reduce positioning accuracy, but also affect its service life; 2. Fire protection The error at the muzzle of the gun is the accumulation and amplification of the errors of the two sets of tandem rotary drive mechanisms, which makes it difficult to align the muzzle of the fire monitor with the center of the fire point; 3. The motor of the rotary drive mechanism is installed on the moving gun body, increasing the The inertia of the system affects the motion performance and response speed of the fire monitor

Abstract

The invention discloses a fire-fighting monitor with in-parallel two-freedom-degree type slewing mechanisms. The fire-fighting monitor comprises a monitor body, a support, a monitor-body horizontal-slewing driving mechanism and a monitor-body pitching-slewing driving mechanism, wherein the monitor body is provided with a monitor pipe; the central line Y of the monitor pipe, the horizontal slewing central line Z of the monitor body and the pitching-slewing central line X of the monitor body are intersected into one point O, and the horizontal slewing central line Z of the monitor body and the pitching-slewing central line X of the monitor body are vertical; the monitor-body horizontal-slewing driving mechanism and the monitor-body pitching-slewing driving mechanism are arranged on the support or a fixed frame which is fixedly connected with the support, and are connected with the monitor body by connecting rods of the monitor-body horizontal-slewing driving mechanism and the monitor-body pitching-slewing driving mechanism.

Description

technical field [0001] The invention belongs to the field of fire-fighting equipment, in particular to an automatic fire-fighting monitor. Background technique [0002] The fire monitor is an important fire extinguishing equipment. The rationality of its structure and the motion accuracy of the slewing mechanism directly determine the positioning accuracy, response speed and use effect of the fire monitor. The structure of existing automatic fire monitor such as figure 1 As shown, including the cannon body, support, cannon body horizontal rotary drive mechanism and cannon body pitch rotary drive mechanism, the two sets of rotary drive mechanisms are both worm and worm gear transmission pairs, and are installed in series on the cannon body, so there are the following problems: 1. The cannon body is a cantilever beam structure with large volume, high center of gravity and low rigidity. It is affected by the recoil force of liquid spray during fire extinguishing, resulting in ...
