Electric device of fire monitor barbette

Abstract

The invention provides an electric device of a fire monitor barbette, which comprises a main box, a motor, a deceleration mechanism, a stroke control mechanism, a manual/electric switching mechanism, a manual operation mechanism and a direct introduction type cable inlet seal mechanism. The deceleration mechanism comprises a worm arranged in the main box, an output shaft connected with the main box by a bearing, a worm wheel and a multichannel worm which are arranged on the output shaft, the worm is vertically engaged with the worm wheel, a worm gear with one end engaged with a motor gear of a motor shaft head is sleeved on the worm. The invention has the beneficial effects that the main box and a control box cover use an aluminum alloy material and a direct introduction type explosion-proof structure, so that the volume of barbette is decreased and the weight of the barbette is mitigated. The electric device of the fire monitor barbette is capable of greatly facilitating the installation and carrying, reducing the design difficulty and manufacture cost of the fire monitor, and raising the explosion-proof performance of the electric device. The deceleration mechanism is composed of a primary gear pair and a primary multichannel worm gear pair and increases the output speed.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to an electric device for a fire-fighting monitor mount with high output speed, good protection performance, light weight and small volume. Background technique [0002] In the existing technology, fire monitor manufacturers often use valve actuators produced by valve actuator manufacturers in order to realize the one-round rotation of the fire monitor gun body. However, the main box cover of the commonly used multi-rotation valve actuators is made of cast iron and The indirect lead-in type explosion-proof junction box structure is adopted, which causes its volume and weight to be too large, which is not convenient for installation and transportation; the explosion-proof junction box, cables and wires of the main box are indirect lead-in type, which makes the gun mount bulky and cumbersome to connect And the manufacturing cost is high; at the same time, t...

[0002] In the existing technology, fire monitor manufacturers often use valve actuators produced by valve actuator manufacturers in order to realize the one-round rotation of the fire monitor gun body. However, the main box cover of the commonly used multi-rotation valve actuators is made of cast iron and The indirect lead-in type explosion-proof junction box structure is adopted, which causes its volume and weight to be too large, which is not convenient for installation and transportation; the explosion-proof junction box, cables and wires of the main box are indirect lead-in type, which makes the gun mount bulky and cumbersome to connect And the manufacturing cost is high; at the same time, the reduction mechanism adopts a large speed ratio worm gear pair structure, so that the output speed is too slow, generally 18r / min
