Description
Technical field
The utility model relates to the apparatus of realizing spaced loading in a kind of open-air or down-hole VCR explosion, specifically a kind of pull-type channel interval device.
Background technology
Employed blast hole channel interval device generally has two kinds of structures in bursting works such as mining, earth and rock works, a kind of is the channel interval device of opening valve outside the hole, the valve venting speed of the used aerosol jar of this product is slow, the powder charge stand-by period is long, influences the operating efficiency of blast hole charging; Another kind is the channel interval device of Open valve in the hole, this product is perfect not enough at present, thereby can not be used for the blast hole of small-bore (as Φ 90mm), and this channel interval device is in transportation and use, the unexpected phenomenon of opening of aerosol valve also appears easily, make product failure, cause unnecessary loss.
Summary of the invention
The purpose of this utility model just provides a kind of pull-type channel interval device, to improve the degree of accuracy of channel interval device placement position, shortens the powder charge stand-by period.
The utility model is achieved in that a kind of pull-type channel interval device, and the aerosol jar is housed in airbag, is connected to lifting rope in the outside of described airbag, is connected to mass in the bottom of described aerosol jar.
The utility model has installed mass additional by the bottom at the aerosol jar, has increased the overall weight of aerosol jar and this channel interval device.In use, just can be earlier this channel interval device be accurately hung onto desired depth in the blast hole with lifting rope, put forward a part on the lifting rope with the aperture exposed parts of blast hole then, put down rapidly more afterwards, aerosol jar in this channel interval device is removed by the gravity one of appended mass to be dashed, thereby the aerosol valve on the aerosol jar is opened under the effect of inertia force, pot liquid ejection and gasification, make the rapid distending of airbag, the desired depth of support in blast hole realized the accurate input of this channel interval device in blast hole and the spaced loading operation in blast hole thus.
Described mass is that weight is housed in box body, the bottom that is connected described aerosol jar suitable for reading of described box body.
Described mass is that weight is housed in polybag, and the top of polybag is bonded in the bottom or the bottom of described aerosol jar.
In the welding of the upper edge of described airbag suspension rod is arranged, the top of described suspension rod and the lower end of described lifting rope join, and the bottom of described suspension rod is connected with described aerosol jar by lanyard.Adopt this structure, valve control mechanism on aerosol jar and the aerosol jar all is encapsulated in the airbag, lifting rope not with the aerosol jar on valve control mechanism directly link to each other, the quiet lifting rope that draws can not opened the aerosol valve, has avoided the product failure that in use causes because of maloperation thus.
The lower end of described lanyard is connected on the control lever of described aerosol jar.
The double-layer seal bag that described airbag is made up of inner bag and the socket of outer bag is to improve product reliability.
Outside at described airbag is with woven bag, with the protection airbag, prevents to scratch.
External beam after described airbag and described woven bag package has the safety belt that will hold out against on the described aerosol jar in the airbag upper edge.So just can avoid in the Product transport process preventing product failure because of the unexpected situation of opening of aerosol valve of loading and unloading due to colliding with takes place.
Described lifting rope is marked with lifting rope length, so just the lifting rope double as can be used for measuring the rope chi, thereby this channel interval device is hung onto desired depth in the blast hole exactly.
The utility model can the desired depth in blast hole be opened the aerosol tank valve, makes airbag fast aeration expansion location, and the powder charge stand-by period in the bursting work has been shortened in the degree of accuracy that has improved channel interval device placement position thus.The breakdown action of the aerosol valve in the utility model is reliable, can reduce the inefficacy and the scrappage of product, reduces production costs.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Surface structure schematic diagram when Fig. 2 is the utility model package.
The specific embodiment
As shown in Figure 1, the airbag of this channel interval device is by the inner bag 3 double-layer plastic sealing bag that 4 sockets are formed with outer bag.Aerosol jar 5 is housed in airbag.Aerosol jar 5 is the special-purpose aerosol jar of channel interval device, can adopt disclosed patent aerosol jar ZL200920254180.0 number.Bottom at aerosol jar 5 is connected with mass.This mass is that weights such as sand, stone or bushel iron piece, the bottom that is fixedly connected on aerosol jar 5 by screw socket or other connected modes suitable for reading of box body 6 are housed in the tubular box body 6 of a upper shed.
In the welding of the upper edge of airbag suspension rod 2 is arranged.The middle part of suspension rod is shaped on a physa sheet, connects the double-deck bag of airbag in order to hot melt.The top of suspension rod 2 connects lifting rope 1, and the bottom of suspension rod 2 connects lanyard 10, and the depression bar 8 of the valve control mechanism in the lower end of lanyard 10 and the aerosol jar 5 is connected.Last strut and tie 8 can make the aerosol valve 9 on the aerosol jar 5 open.
Lifting rope 1 is a kind of rope that length mark is arranged.The setting of length mark can be every meter rice number of locating to mark correspondence at lifting rope 1, can also be to do length mark on the surface of lifting rope 1 with the different colours section, and the length of each color segment is 1 meter, and forming with rice is the length mark of unit.Certainly also can use other modes to be provided with or the length of mark lifting rope 1.Like this, when in blast hole, throwing in this channel interval device, just can accomplish accurate input.
For improving the protective of airbag, this channel interval device is with woven bag 11 in the outside of airbag, and, with woven bag 11 after airbag is wrapped in, push away on the aerosol jar with interior dress, make the upper end of aerosol jar hold out against upper edge at airbag, afterwards, again in the outside of the woven bag 11 of package, a safety belt 12 (as shown in Figure 2) is tightened in the bottom of the bottom margin of aerosol jar relatively, to prevent the slip of aerosol jar in airbag, can avoid this channel interval device thus in transportation and process that prepare to use, because of the generation of the unexpected failure conditions that play caused of aerosol jar.
Using method of the present utility model is, the safety belt 12 that will be banded in this channel interval device outside is earlier opened, with lifting rope this channel interval device is transferred to the degree of depth predetermined in the blast hole in advance again, to be entangled on the pin at the lifting rope of blast hole aperture exposed parts and slam, upwards lift the lifting rope 1.5-2 rice in the hole, loose one's grip then and transfer lifting rope rapidly, aerosol valve 9 on the aerosol jar 5 relies on inertial force to be opened, liquid in jar is ejection and gasification rapidly, airbag expands rapidly, support realizes the spaced loading operation in blast hole thus at the blast hole degree of depth place that sets.
