Belt winding and unwinding device and fire truck

Abstract

The invention provides a belt winding and unwinding device and a fire truck and belongs to the field of fire-fighting equipment. The belt winding and unwinding device comprises a belt guide mechanism, a belt winding mechanism and a rotating mechanism. The belt guide mechanism is connected with the belt winding mechanism. The belt winding mechanism is connected with the rotating mechanism and can rotate under the drive of the rotating mechanism. The fire truck comprises a truck body and the belt winding and unwinding device. The rotating mechanism of the belt winding and unwinding device is mounted on the top of the truck body. The belt winding and unwinding device can achieve quick winding and unwinding of fire-fighting water belts in multiple positions and meanwhile can achieve automatic dragging, placing and lifting up of fire-fighting water pumps, so that the operation convenience of the firefighters and the practicability of the belt winding and unwinding device are improved effectively, and the defects existing in the prior art are made up for; and the belt winding and unwinding mechanism is mounted on the top of the fire truck, and flexible and quick winding and unwinding of the fire-fighting water belts can be achieved, so that related operation of the firefighters is facilitated, and accordingly the defects in the prior art are made up for.

Description

Technical field [0001] The invention relates to the field of fire fighting equipment, in particular to a retractable belt device and a fire truck. Background technique [0002] The existing retractable belt mechanism on the roof of the fire truck can only release and retract the belt at the front end of the fire truck, and the fire water pump needs to be manually released and lifted, which is inconvenient to operate and poor in practicability, and cannot achieve fast and flexible retracting of the fire hose. Put the problem. Summary of the invention [0003] The purpose of the present invention is to provide a retractable belt device, which can easily realize the rapid retracting and releasing of the fire hose in multiple positions, and at the same time, it can realize the automatic release and holding of the fire water pump, thereby effectively improving the convenience of firefighters. And the practicability of the retractable belt device of the fire truck. [0004] Another obje...
