Description

A kind of dredge pipe buoy

Technical field

The utility model relates to the design and the manufacturing technology field of the mud delivery pipeline that uses in the dredging works, relates in particular to a kind of dredge pipe buoy.

Background technology

The mud delivery pipeline that mechanical dredging workss such as river course, navigation channel, basin are dredged deeply, harbour foundation trench all need the spoil disposal pipeline to be formed by connecting transports.As the mud pipe in the mud delivery pipeline, that uses so far has various self-floating metal, a nonmetal mud pipe always, also has by the metal mud pipe of pontoon supporting etc. multi-form.Increasing along with continuous progress in science and technology and mechanical dredging works amount, the product of strap-on supporting metal mud pipe is more and more, strap-on dredge pipe buoy is also had nothing in common with each other, at present be the medium density polyethylene buoyancy aid at the buoyancy aid that extensively uses, the shell of this buoyancy aid is made by medium density polyethylene, inner chamber filled high polymer expandability foamed material, two halfpipe buoyancy aid bodies connect as one by bolton, its advantage is corrosion-resistant, but its shortcoming is to use as easy as rolling off a log generation aging under the direct projection of sunshine, influence application life, not anti-collision and easily cracked, and cause buoyancy to descend, and mud pipe is sunk under water, cause much losses in the use.Therefore how designing also as those skilled in the art, processing and manufacturing goes out the buoyancy that can keep buoyancy aid, have ageing-resistant, anti-collision, shock resistance, wear-resistant, tear-resistant buoyancy aid again, remedy the deficiency in the background technology, this is a problem that needs to be resolved hurrily with the needs that satisfy mechanical dredging works mud delivery pipeline.

Summary of the invention

Goal of the invention of the present utility model is to improve disadvantages of background technology, and provide a kind of anti-collision, wear-resistant, tear-resistant, ageing-resistant, in conjunction with firmly, dredge pipe buoy that heat resistance is good.

For achieving the above object, the utility model is to adopt following technical scheme: a kind of dredge pipe buoy, it is to be formed by connecting by two semi-tubular buoyancy aid bodies, and its special character is that described dredge pipe buoy comprises that the buoyancy aid body is for establishing an airtight cavity that is hollow structure between the inner wall layer that connects one and the outer wall layer.

The utility model is compared with background technology has following obvious improvement and outstanding characteristics: the first owing to taked will be connected establishes a technical scheme that is the airtight cavity of hollow structure between the inner wall layer of one and the outer wall, thereby not only reach the further technical characteristic that has improved the buoyancy of buoyancy aid, and make the anti-collision ability of buoyancy aid, ageing-resistant, heat resistance is more excellent, setting up by the metal buoyancy aid between mud pipe and the buoyancy aid particularly, really make it become the integral body that combination is firm, the stretch-proof that has improved dredge pipe buoy described in the utility model greatly, shock resistance, resistant to bending strength character.It two is the utility model owing to be provided with the technical scheme of elastomeric layer and fibrae circulares casing play in the outer wall layer of buoyancy aid body, inner wall layer, reached and made between each layer of buoyancy aid body described in the utility model in conjunction with firm, improved the performance of wear-resistant, the tear-resistant intensity of buoyancy aid greatly with its good rigidity and hardness, prolong product application life, reduced the use cost of dredge pipe buoy.The inventor is in design process and carry out sample processing and small lot trial-production, has proved every performance indications numerical value of background technology head and shoulders above by self testing and destructive testing, and has prepared to deliver the quality examination center and further detect and provide report.This product is confirmed as the project of filling the domestic gaps through the retrieval of Shandong Province's information retrieval center.

The specific embodiment

Describe the concrete CONSTRUCTED SPECIFICATION of a kind of dredge pipe buoy of the utility model in detail and install and use process below in conjunction with accompanying drawing.

Embodiment 1: a kind of dredge pipe buoy (referring to accompanying drawing 1, accompanying drawing 2), it is to be formed by the bolton connection that interts in bolt nest hole 4 by two semi-tubular buoyancy aid bodies.The buoyancy aid body is to be processed through cutting by steel plate, it includes the buoyancy aid body end 2 of two halfpipe buoyancy aid body outer wall layers 1, two semicircular ring, two halfpipe buoyancy aid inner body wall layers 3, an integral body that processes by welding procedure, its buoyancy aid body outer wall layer 1 and buoyancy aid local terminal end 2 constitute an airtight cavity 5 that is hollow structure between the buoyancy aid inner body wall layer 3.More than constitute a static structure of a kind of dredge pipe buoy of present embodiment.

The technical scheme of the described a kind of dredge pipe buoy of present embodiment is applicable to the mud pipe that carries out mechanical dredging works on rivers, lake, harbour and other places and use, and operating environment is a little better, and wind and wave resistance, impact resistant capability require lower slightly operating condition.

Embodiment 2: a kind of dredge pipe buoy (referring to accompanying drawing 3, accompanying drawing 4), it is poor with operating environment, and inclement condition is a precondition, has wind and wave resistance, impact resistant capability is strong, and the activity duration is long etc., and multiple particular characteristic requires and a kind of dredge pipe buoy of design.Technical scheme described in the present embodiment is except that identical with embodiment 1, other difference has: whole one deck (can increase by 3 to the 5 layers as requested) fiber reinforcement 7 in the form of a ring at least that is wound with of the lateral surface of the outer wall layer 1 of two halfpipe buoyancy aids of first body, and be one with glue bonding blending, coat with the Thermoplastic Elastomer, Olefinic material again, the inner wall layer 3 of two halfpipe buoyancy aid body, buoyancy aid body joint 9 usefulness Thermoplastic Elastomer, Olefinic coat, thereby the formation buoyancy aid body outside is fastenedly connected the elastomeric layer 8 into one.It two is that buoyancy aid body end 2 prolongs vertically, sets up a conical head 6 (also available hemispherical, dished (torispherical) head) and is provided with the bolt nest hole 4 that Bolt Connection is used, to increase the seizing force of buoyancy aid body and spoil disposal body.More than constitute another static structure of a kind of dredge pipe buoy of the utility model.
