Problems solved by technology

In the process of ventilation or dust collection, there are no reliable sealing or compensation measures for the gaps, and the air leakage rate is large, which affects the ventilation or dust collection effect
In the actual application of the vacuum cover, measures such as manual winding of flexible materials are also taken to reserve gaps to avoid collisions. However, due to the limited installation height and space when implementing measures such as winding flexible materials, it results in labor-intensive, time-consuming, and Inconvenient to operate
Until now, there is no convenient and reliable device or measure to solve the air leakage in the gap between the fixed pipe and the switch joint of the vacuum hood

Abstract

The invention discloses a driving type expansion joint and application thereof. The driving type expansion joint includes an expansion joint main body, the two ends of the expansion joint main body are fixedly provided with end flanges, the end flange at one end is fixedly provided with a driving mechanism, and the telescopic end of the driving mechanism is connected to the end flange at the otherend. The driving type expansion joint can achieve active extension and compression, collision between a dust suction hood and a fixed pipe during movement of the dust suction hood can be avoided, andcollision accidents and equipment damage are avoided; and a gap generated after positioning and docking of the dust suction hood and the fixed pipe can be made up, the air leakage rate is reduced, the pipe ventilation and dust collection efficiency is improved, manual sealing is saved, time and labor are saved, and operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pipeline ventilation, and in particular relates to a driving expansion joint and its application. Background technique [0002] In the ventilation or environmental protection dust removal pipeline system, some pipelines or dust collection hood facilities need to frequently move through the track and switch to one or more other fixed pipelines. Sufficient clearance must be left between the pipe axes to avoid collisions. In the process of ventilation or dust collection, there are no reliable sealing or compensation measures for the gaps, and the air leakage rate is large, which affects the ventilation or dust collection effect. In the actual application of the vacuum cover, measures such as manual winding of flexible materials are also taken to reserve gaps to avoid collisions. However, due to the limited installation height and space when implementing measures such as winding flexible materials, it result...
