Flexible air pipe winding and unwinding device for air supply

Abstract

The invention relates to a flexible air pipe winding and unwinding device for air supply. The device comprises an air pipe winding drum assembly, a flexible air pipe, two winding drum seats, a rotary air inlet assembly and a rotary driving assembly for driving the air pipe winding drum assembly to rotate, the air pipe winding drum assembly comprises a winding drum main body, a winding drum air pipe shaft and a winding drum rotating shaft, the rotary air inlet assembly comprises an air inlet pipe, a fixed air pipe and a rotary air pipe rotatably inserted into the fixed air pipe, the air outlet end of the air inlet pipe is connected with the air inlet end of the fixed air pipe, the air outlet end of the rotary air pipe is fixedly connected with the winding drum air pipe shaft, and an output shaft of the rotary driving assembly is fixedly connected with the winding drum rotating shaft. Compared with the prior art, automatic winding and unwinding of the flexible air pipe on the winding drum main body can be achieved, the requirement for movable air supply is effectively met, and the device is safe and reliable in structure and long in service life.

Description

technical field [0001] The invention relates to the field of air supply devices, in particular to a flexible air duct retractable device for air supply. Background technique [0002] In industrial production sites, air supply devices or air delivery devices are often required to meet the air exchange requirements of equipment and personnel, or to deliver clean air to the site to disperse toxic and harmful gases, or to directly pass unnecessary gases through the delivery pipeline Exhaust the site to ensure that the air in the equipment installation area and personnel work area is qualified. Such ventilation or air supply devices and air supply pipes are widely used, and various common flexible air ducts or rigid air ducts are fixedly arranged at industrial production sites to play the role of ventilation and air transportation. In actual application sites, there are often requirements for air supply or air delivery to mobile equipment. The short-distance method uses flexible...

Problems solved by technology

In actual application sites, there are often requirements for air supply or air delivery to mobile equipment. The short-distance method uses flexible air ducts to move with the movement of mobile equipment. Flexible air ducts are often hung or placed on the ground or equipment on the bottom surface. In addition, Some mobile equipment and the air supply equipment are located at a height difference, resulting in the layout of the air duct with an inclined or vertical feature. The mobile equipment or the position to be installed needs to be moved vertically or obliquely. , the method of direct dragging and it is easy to damage the pipeline and cause leakage. The main reason is that the flexible pipeline for ventilation is in the process of hanging or directly dragging. It is very easy to twist, knot or fold in the air, resulting in deformation of the flexible pipe. This situation will affect the flow area of ​​the air pipe, increase the resistance of gas transportation, and easily damage the gas pipeline, which will shorten the service life of the gas pipeline. Shorter; In addition, the air supply distance using the above method is relatively short, if the distance is longer, there is currently no corresponding method
