Description
Technical Field
The utility model relates to a local fan dryer especially relates to a local fan dryer connecting device in pit.
Background
The local fan under the coal mine is commonly used for tunneling roadway ventilation and air exchange, and the length of the local fan is often required to be adjusted along with the tunneling of coal and rock roadways, so that the conventional local fan air duct often adopts flexible air ducts such as corrugated pipes, but in the actual use process, because the air duct is long in length, the local fan air duct needs to be folded and stacked one by one due to the lack of guide equipment in the disassembly and folding process, and the working efficiency is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a local fan dryer connecting device in pit, through setting up ring, engaging lug, wire rope and fastener, make the dryer slide along wire rope length direction, realize the quick of dryer and release and folding.
Local fan dryer connecting device in pit include: the air duct comprises a plurality of circular rings, connecting lugs, steel wire ropes and fasteners, wherein the circular rings are sleeved along the length direction of the air duct, and the inner diameter of each circular ring is adapted to the outer diameter of the air duct; the connecting lug is fixedly connected with the outer edge of the circular ring, and a through hole is formed in the connecting lug; the steel wire rope sequentially passes through the through holes on the connecting lugs; the fastener corresponds ring and dryer suit position setting for fixed ring and dryer.
During the installation, at first with the ring suit on the dryer fastener position, through fastener fastening dryer, then pass the through hole on each engaging lug in proper order through wire rope, when needing to let out the dryer, pulling tip ring drives the dryer and slides along wire rope, can realize the quick expansion of dryer, when needing folding dryer, corresponding, to opposite side pulling ring, drives the dryer and slides along wire rope, realizes the quick folding of dryer.
The fastener sets up a set ofly at least along dryer circumference.
In order to strengthen the firmness of the connection of the air duct and the circular ring, the fastener is at least provided with one group along the circumferential direction of the air duct.
The fastener includes connecting band and wiring rope, connecting band one side and dryer outer wall fixed connection, the connecting band opposite side sets up wiring rope.
The binding rope can be a cloth rope or a steel wire rope, and the circular ring is fixedly connected with the air duct in a knotting or binding mode.
The utility model has the advantages that: through setting up ring, engaging lug, wire rope and fastener, make the dryer slide along wire rope length direction, realize the quick of dryer and release and fold.
