Fire-fighting belt take-up mechanism on fire-fighting truck

Abstract

The invention relates to the technical field of fire-fighting belts, and discloses a fire-fighting belt take-up mechanism on a fire-fighting truck. The fire-fighting belt take-up mechanism comprises abase and a reset assembly, wherein a bracket is fixedly mounted at the top end of the base; a motor is fixedly mounted at the top end of the base; a transmission belt is fixedly mounted on the outerwall of an output shaft of the motor; a transmission column is fixedly mounted on the inner wall of the top of the transmission belt; and a protection ring is movably connected to the outer wall of the transmission column. According to the fire-fighting belt take-up mechanism on the fire-fighting truck disclosed by the invention, the transmission belt can be driven to rotate through the rotation of the output shaft of the motor, the transmission column can be driven to rotate through the rotation of the transmission belt, under the effect of the transmission column, a mounting head also startsto rotate, and a fire-fighting belt main body movably connected with the mounting head is driven to rotate, so that the process of taking up the belt is started; and in the process, an elastic rope can maintain pulling force, so that a tightening plate always maintains acting force in the direction of the center of the protection ring, the belt take-up effect of the fire-fighting belt main body is compact, and the effect of automatically taking up the belt is achieved.

Description

technical field [0001] The invention relates to the technical field of fire belts, in particular to a fire belt take-up mechanism on a fire truck. Background technique [0002] The fire hose, also known as the water hose, is a tubular belt fabric that can withstand a certain liquid pressure. According to the raw materials used, it can be divided into fire hoses such as cotton, awn hemp, linen, and synthetic fiber lining rubber; according to the pressure resistance, it can be divided into Ordinary and high-pressure fire hoses, high-pressure fire hoses are usually made of high-strength and low-elongation polyester filaments, woven into tube blanks with double-shuttle circular looms, lined with 1-3mm thick rubber or coated with a layer of thinner inside and outside the tube blanks. The thin polymer synthetic material makes it able to withstand high pressure without leakage, corrosion resistance, wear resistance, and lightness. After the fire hose is finished, it needs to be wou...

[0002] The fire hose, also known as the water hose, is a tubular belt fabric that can withstand a certain liquid pressure. According to the raw materials used, it can be divided into fire hoses such as cotton, awn hemp, linen, and synthetic fiber lining rubber; according to the pressure resistance, it can be divided into Ordinary and high-pressure fire hoses, high-pressure fire hoses are usually made of high-strength and low-elongation polyester filaments, woven into tube blanks with double-shuttle circular looms, lined with 1-3mm thick rubber or coated with a layer of thinner inside and outside the tube blanks. The thin polymer synthetic material makes it able to withstand high pressure without leakage, corrosion resistance, wear resistance, and lightness. After the fire hose is finished, it needs to be wound up. However, this process usually needs to be done manually, so It will bring some troubles to firefighters, and there may be a certain amount of moisture remaining in the firefighting belt after the belt is closed. Therefore, the demand for high-reliability products is imminent, so we propose a fire belt take-up mechanism on a fire truck, which has the advantages of automatic take-up and not easy to store water, to solve the above problems
