Abstract

The utility model discloses a hanging air pipe and relates to a mining ventilation air pipe. Two long sides of the rectangular air pipe cloth are folded in half and sewed into an air pipe with an upper convex side, a cable with the same length of the air pipe is mounted on a top end part in horizontal direction of the convex side, the cable and an outer side of the convex side are sealed by heat with a wrapped edge, and the air button holes are fixed with isometric spaces in the horizontal direction. The utility model has a simple structure, a reasonable design and an easy processing. Compared with the products in art, the using life of the utility model prolongs 2 to three times. Therefore, an integral cost of the utility model is low and the ventilation work efficiency of the mining air pipe is improved. The application of the device increases firmness and stability of the hanging air pipe.

Description

The suspension type air duct

Technical field

The utility model relates to a kind of mining vent wind cone.

Background technology

At present, mining air duct equidistantly installs the wind buttonhole in the chimb position horizontal direction of air duct butt joint usually, and above-mentioned air duct uses yielding, easily eye of wind button is torn during use, and application life is short, influences the progress of work, needs to change air duct, integrated cost height.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, the suspension type air duct of long service life.

In order to achieve the above object, the technical solution adopted in the utility model is: two long limit doublings of rectangle air duct cloth are made to constitute to go up and are the air duct of chimb shape, the rope identical with air duct length is equipped with at position, chimb horizontal direction top, a bound edge is pressed by heat seal in the rope and the chimb outside, and its horizontal direction equidistantly is fixed with the wind buttonhole.

The utility model has the advantages that:

Processing simple in structure, reasonable in design, easy, this product is than existing long product lifecycle 2-3 times, so integrated cost is low, has improved the operating efficiency of mining air duct air-supply.The fastness, the stability that adopt this device to increase to hang air duct.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 2 as can be known, the utility model is that two long limit doublings of rectangle air duct cloth are made constitute to go up and are the air duct 2 of chimb 1 shape, the rope 3 identical with air duct 2 length is equipped with at position, chimb 1 horizontal direction top, a bound edge 4 is pressed by heat seal in the rope 3 and chimb 1 outside, and its horizontal direction equidistantly is fixed with wind buttonhole 5.

Described rope 3 is the rope made of hemp, wire rope or nylon rope.

Bound edge 4 described in the utility model is to adopt hot-press method bound edge 4 firmly to be pressed together on chimb 1 position of air duct 2, simultaneously along air duct 2 horizontal directions bound edge 4 bottoms being sewed with twice binding 6 links to each other with chimb 1 bottom, chimb 1 top is provided with the rope 3 (ropes made of hemp identical with air duct 2 length, wire rope) by bound edge 4 rope 3 is fixed on the air duct 2, equidistantly install wind buttonhole 5 along air duct 2 horizontal direction bound edges 4 positions again, air duct 2 intensity are strengthened greatly, the interior air duct 2 of the drive that air duct 2 is hung is difficult for tearing, prolonged the application life of air duct 2, make mining activity efficient improve 2-3 doubly, saved because of air duct 2 damages and caused shut-down, stopping production is the ideal product of present mining air duct.

The utility model adopts heat seal or adhering process, be the 5cm of the wide edge-covering cloth of 10cm is wrapped in the air duct erecting by overhang by heat-sealing machine heat seal or viscose glue mode one side promptly by fabric width, formation is with air duct coated cloth surface-coated layer material heat fused or be adhesive in one on the whole, take identical way, during once more second half 5cm edge-covering cloth heat seal or viscose glue hanging rope is wrapped up therebetween.When the eye of wind that is provided with on this device air duct was buckled because of the whole joint of external force effect disengaging air duct, its hanging rope just can play a role to play and continue to hang air duct, allows it continue the effect of normal ventilation.This device has an integral body that makes erecting by overhang form a heat seal or adhesive means, whole firm, solid, practical, attractive in appearance, and hang straight formation straight line in use, and buckle when coming off hanging rope at the eye of wind of air duct and can also play to replenish and hang effect, can be described as the effect of playing dual fail-safe.

Claims (2)

1. suspension type air duct, comprise wind buttonhole, rope, it is characterized in that: two long limit doublings of rectangle air duct cloth are made to constitute to go up and are the air duct (2) of chimb (1) shape, the rope (3) identical with air duct (2) length is equipped with at position, chimb (1) horizontal direction top, a bound edge (4) is pressed by heat seal in the rope (3) and chimb (1) outside, and its horizontal direction equidistantly is fixed with wind buttonhole (5).

2. suspension type air duct according to claim 1 is characterized in that: described rope (3) is the rope made of hemp, wire rope or nylon rope.
