The light anti-abrasion delivery tube is mainly used for concrete delivery.

Description

The light wear-resistant concrete delivery pipe
Technical field
The present invention relates to a kind of concrete delivery pipe, particularly a kind of light wear-resistant concrete delivery pipe.
Background technique
At present, when construction industry is constructed, generally all adopt concrete mixer, drag the delivering concretes such as pump.Power by these machineries provide can pour into operation to the position of appointment with concrete conveyance by conveyance conduit.
In the concrete conveyance operation process, delivery pipe will bear larger pressure and pulling force and be subject to erosion and wearing and tearing, so delivery pipe very easily damages.Require to have higher intensity, toughness and hardness because improving the stability of carrying operation process, the convenience of installation, carrying, lighter quality, present delivery pipe mainly contains the homogenous material delivery pipe; Or by the composition metal delivery pipe that different metal material consists of, also there is patent to propose to adopt polymer matrix composites to substitute the outer tube of bimetallic material composite conveying pipe, to reduce total quality.
This resin base composite conveying pipe reduces total quality, comes adpting flange because its bend pipe adopts the welding of the interior outside to strengthen steel plate, in the extremely difficult realization of practice of construction process; And straight tube adopts the outside projection of flange to be connected with resin base, very easily comes off again.Resin-based materials has higher intensity and toughness, but its springform material deficiency is less 10 times than steel, and it is not enough that this patent fails to solve its rigidity, and resin layer is out of shape, causes the cracked deficiency of inner tube behind the inner tube pressurized.
Applied for disclosed patent CN201110229216 on December 28th, 2011 " a kind of concrete delivery pipe and manufacture method thereof " on 08 11st, 2011 such as Li Zongxian, it adopts novel hypereutectic high-chromium white cast iron material, fusible pattern, sand mold or centrifugal casting moulding are to satisfy the requirement of high-wearing feature; Curved outer tube, straight outer tube adopt low carbon high-strength Steel Pipe Heat pushing or cold drawn forming, though have the characteristics such as cost is low, easy-formation, its quality is heavier, has increased operation easier.
Summary of the invention
The purpose of this invention is to provide and a kind ofly have high wear resistance, high strength, be difficult for the light wear-resistant concrete delivery pipe that explosion, working life are long, quality is light.
The technical solution adopted for the present invention to solve the technical problems is: it comprises flange 1 and wear-resistant pipe 2, flange 1 is formed a team affixed with wear-resistant pipe 2, wear-resistant sleeve 3, flange 1 engage sleeves is contained in wear-resistant sleeve 3 and wear-resistant pipe 2 outsides, wear-resistant pipe 2 outsides are coated with wear resistant outer layer 6, be provided with stiffening rib 4 in the wear resistant outer layer 6, flange 1 also is provided with flange fixed hole 5, one or more flange reinforcing ribs can be set pass flange fixed hole 5 connections two end flange.
Wear resistant outer layer 6 of the present invention can adopt glass fibre reinforced plastics, resin, fiber base or engineering plastics sill.
Wear-resistant pipe 2 of the present invention can adopt the high-abrasive materials such as rich chromium cast iron, tool steel, spring steel or wear-resistant ceramic to make, and can be made into straight tube or bend pipe, the outer stiffening rib 4 that arranges can adopt around or the mode of straight cloth arrange.
Wear-resistant sleeve 3 of the present invention can adopt high-chromium casting or wear-resistant ceramic material to make.
The invention has the beneficial effects as follows: have high wear resistance, high strength, be difficult for explosion, working life is long, quality is light.
