A kind of reusable wear-resistant concrete pump pipe

Technical field

The utility model relates to concrete pump conveyance conduit technical fields, and in particular to a kind of reusable wear-resisting mixed Solidifying soil pump line.

Background technique

Currently, in the field of construction, often using concrete, these concrete are conveyed, in addition to a small amount of barreled etc., In heavy construction, often use concrete mixer, concrete mixer abbreviation pump truck again, be it is a kind of using pressure by concrete It is continuously conveyed along pipe special to the mechanical equipment of required position, except the component part of automobile, pump truck is mainly by concrete Delivery pump and conveyance conduit composition, can be divided into piston type, squash type or hydraulic diaphragm formula by structure type concrete pump, mix Solidifying soil delivery pump remilitarizes scalable or tortuous conveyance conduit on automobile chassis, just forms pump truck.

Concrete pump conveyance conduit is the important component of pump truck, referred to as pump line.Pump line is with concrete conveyance The appearance of pump and a kind of architectural engineering accessory occurred simultaneously, it substantially increases the efficiency of construction, by artificial or The operation mode of one barrel of bucket of crane or a pipeful of bucket transfer concrete has been changed to the place for being directly poured concrete conveyance to needs Operation mode, improve construction efficiency nearly a hundred times.

Existing pump line mostly uses high-intensitive manganese steel pipe, or using the high-intensitive manganese steel pipe of inner wall high-frequency quenching and double Layer pipe, however these pump lines have the following disadvantages:

(1) inner wall abrasion is very fast in use for high-intensitive manganese steel pipe, needs to frequently replace because cause cannot be after for abrasion The continuous pump line used, so that the integrated operation cost of this kind of pump line is high；

(2) the high-intensitive manganese steel pipe of inner wall high-frequency quenching compares common high-intensitive manganese steel pipe, has made service life It improves, but due to the influence of existing quenching technical, the depth for quenching layer is that non-uniform, relatively thin quenching layer defines and makes With the service life, so that the service life that this kind of pump line can improve is limited；

(3) bimetallic tube is at high cost, the deficiency in economic performance of this kind of pump line.

Utility model content

The purpose of this utility model is to provide a kind of reusable wear-resistant concrete pump pipes, to solve existing pump The problem of pipe service life due to not wear-resisting is low, operating cost is high and deficiency in economic performance.

To achieve the above object, the utility model provides a kind of reusable wear-resistant concrete pump pipe comprising Outside steel pipe and silicon carbide lining are lining in the inside of the outside steel pipe, the silicon carbide lining in the silicon carbide lining It is fitted closely between the outside steel pipe by adhesive.

Wherein, the outside steel pipe is manganese steel pipe.

Wherein, the silicon carbide lining is coat of silicon carbide.

Wherein, anticorrosive paint layer is coated in the inner wall of the outside steel pipe.

Wherein, anti-cracking protective layer is additionally provided on the excircle of the silicon carbide lining.

The utility model has the advantages that

Reusable wear-resistant concrete pump pipe provided by the utility model, outside steel pipe is to keep pump line that should have Intensity and toughness, to bear the interior pressure of pump truck output cement slurry, silicon carbide lining improves pump line inner wall wear-resisting property, Abrasion of the concrete to pump line inner wall is reduced, and then extends the service life of pump line, avoids occurring pump line leakage in the construction process The generation of the failures such as slurry, booster, makes the pump of unit concrete at the non-cutting time for saving a large amount of shutdown maintenance, replacing pump line It send cost to substantially reduce, while also can guarantee the progress of construction, improve construction quality；Between silicon carbide lining and outside steel pipe It is fitted closely by adhesive, after silicon carbide lining is worn to a certain extent, passes through adhesive on the inside of outside steel pipe and bond New silicon carbide lining, to reuse outside steel pipe, further reduces operation to supplement worn-out silicon carbide lining Cost is increased economic efficiency.
