AI Technical Summary

Technical Problem

The limited range of rotation of the fire hose reel inside the fire box makes the fire hose prone to bending, jamming, friction and wear when pulled out, affecting its service life and water supply flow.

Method used

A cantilevered fire hose reel was designed. Through components such as a base, fixed support, cantilever arm, rotating shaft, and bidirectional thrust ball bearing, the fire hose reel can be adjusted from a vertical to a horizontal state, increasing the working space, ensuring that the direction of pulling out the fire hose is consistent with the direction of the reel, and reducing friction and bending.

Benefits of technology

This solves the problem of limited rotation range of fire hose reels, avoids excessive bending and jamming of fire hoses, extends service life, maintains efficient water flow, and improves fire extinguishing efficiency.

Abstract

This utility model discloses a cantilevered fire hose reel. A fixed support column is vertically fixed to the center of a base, with a fitting groove at its lower end. The bottom end of the cantilever arm is hinged to the fixed support column via a first rotating shaft and has a fitting head matching the fitting groove. The cantilever arm can rotate around the shaft from a vertical position to a horizontal working position, at which point the fitting head is embedded in the fitting groove for limiting support. An anchor plate is provided below the fixed support column, and the fitting head is locked by a pull rod and a safety pin. A fixed head is fixedly installed at the top of the support arm. A bidirectional thrust ball bearing is fixed inside the fixed head, and a rigid water pipe is fixed to the inner ring of the bidirectional thrust ball bearing and can rotate freely. One end of the rigid water pipe has a movable water inlet connector, and the other end is closed. The pipe body is fixedly connected to a first hose reel frame, a second hose reel frame, a bent water outlet connector, and a movable water inlet connector. This utility model achieves an externally cantilevered fire hose reel, solving problems such as hose bending, jamming, and friction wear caused by space limitations inside fire boxes.
