Description

A crawler-type remote control wind fire extinguisher fan transmission mechanism

technical field

The invention relates to a fan transmission mechanism of a crawler-type remote-controlled wind fire extinguisher. Specifically, by manually operating the clutch, the intermediate shaft assembly and the main shaft of the high-pressure centrifugal fan realize the control of the working state of the high-pressure centrifugal fan through the power transmission of the pulley .

Background technique

In recent years, the frequency of large-scale forest fires has increased significantly compared with the past, threatening human life and property safety at all times. Forest fire is a natural disaster that is sudden, destructive, and difficult to deal with and rescue. Due to terrain, weather and other reasons, carbon dioxide fire extinguishers, dry powder fire extinguishers and other fire extinguishers suitable for small area fires are not suitable for fighting forest fires, so the research and development of related fire extinguishing equipment should be paid attention to. At present, energy-saving and environmentally friendly portable fire extinguishers are widely used to extinguish forest fires. However, due to the limitation of manual loads, portable fire extinguishers often have low power and low fire extinguishing efficiency. For this reason, invent a kind of crawler-type remote control wind fire extinguisher to effectively improve fire extinguishing efficiency, improve the safety of fire extinguishing operators.

Contents of the invention

The purpose of the present invention is to provide a crawler-type remote control wind fire extinguisher fan transmission mechanism with simple structure, easy operation and easy manipulation.

In order to achieve the above object, the technical solution adopted by the present invention to solve the technical problem is: the right side of the pulley clutch is connected with the separation assembly 1 and the separation assembly 2, and the joystick is connected with the separation assembly 2 through the joystick connecting rod. When the fire extinguisher is close to the fire source, manually operate the joystick to merge the separation assembly 2 and the separation assembly 2, and the power from the engine is transmitted to the pulley clutch through the belt, and then the power is transmitted to the intermediate shaft connected with the pulley clutch, The intermediate shaft drives the two large pulleys at the right end, and the large pulley on the right transmits power to the small pulley of the right fan through the belt, and the small pulley of the right fan drives the main shaft of the right fan to rotate, so that the right high-pressure centrifugal fan starts At the same time, the left large pulley transmits power to the left fan small pulley through the belt, and the left fan small pulley drives the left fan shaft to rotate, so that the left high-pressure centrifugal fan starts to work.

The invention has the advantages of simple structure, easy manipulation, manual clutch control of the ventilator, and high transmission efficiency.

Detailed ways:

Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

The present invention mainly consists of a right fan assembly (1), a fan connecting plate (2), a left fan assembly (3), a joystick connecting rod (4), a joystick (5), and a joystick chuck (6) , Intermediate shaft assembly (7) and belt (8) constitute. The right fan assembly (1), the left fan assembly (3) and the intermediate shaft assembly (7) are fixed on the fan connecting plate (2); the two large pulleys (7-5) pass through two belts respectively Connect with the small pulley of the fan on the left side (3-2) and the small pulley of the fan on the right side (1-5) to carry out power transmission. Among them, the intermediate shaft assembly (7) is mainly composed of pulley clutch (7-1), bolt (7-2), intermediate shaft connecting plate (7-3), set screw (7-4), large pulley ( 7-5), intermediate shaft spacer sleeve (7-6), flat key (7-7), intermediate shaft gland (7-8), intermediate shaft (7-9), vertical seat bearing (7-10 ), separation assembly 1 (7-11), separation assembly 2 (7-12); separation assembly 1 (7-11) is fixed with the intermediate shaft connection plate (7-3) by bolts (7-2) ;The vertical seat bearing (7-10) is fixed with the intermediate shaft connecting plate (7-3) through the flat washer (7-10-1) and the bolt (7-10-2); the joystick (5) is fixed through the joystick The connecting rod (4) is connected with the separation assembly 2 (7-12), and the joystick (5) can be manually switched in the joystick chuck (6) to achieve separation assembly 1 (7-11) and separation assembly 2 (7-12) are separated or merged to control the work of the high-pressure centrifugal fan; the two large pulleys (7-5) are fixed with the intermediate shaft (7-9) by the flat key (7-7) to realize power transmission.

The working process of the present invention is: under normal state, separation assembly 1 (7-11) and separation assembly 2 (7-12) are in separation state, and intermediate shaft does not rotate. When the fire extinguisher is close to the fire source, manually switch the joystick (6) to merge the separation assembly 1 (7-11) and the separation assembly 2 (7-12), and the power from the engine is transmitted to the pulley clutch (7 -14), now drives the intermediate shaft (7-9) to rotate, and the intermediate shaft (7-9) drives two large pulleys (7-5) to rotate. The right large belt pulley (7-5) transmits power to the right fan small pulley (1-5) through the belt (8), and the right fan small pulley (1-5) drives the right fan main shaft (1-5). 5) Rotate, so that the right high-pressure centrifugal fan (1-1) starts to work; at the same time, the left large pulley (7-5) transmits power to the left fan small pulley (3-2) through the belt (8) ), the left fan small pulley (3-2) drives the left fan main shaft (3-5) to rotate, thus the left high-pressure centrifugal fan starts to work.
