Rate, process cost is added, through eliminating substantially.2. quenched using seamless steel steel pipe or No. 45 welded tubes by inwall at heat
Reason, to increase its anti-wear performance, present quenching pipe can improve to 20,000 to 2.5 ten thousand cubes or so of delivering concrete amount, with economy
It is applicable and has obtained market and widely utilize.3. draw the external composite straight pipe of mouth, outer tube is common seamless steel pipe, inner sleeve be potassium steel or
High-speed steel material inner tube, the method anti-wear performance is higher, and shelf life, product design was more about at 40,000 to 4.5 ten thousand cubes or so
Change quick, but be due to domestic without manufacturer, import price is higher, increases cost.
Utility model content
The purpose of this utility model is in order to solve the above problems, to devise a kind of automobile-used high-performance abrasion-proof of concrete pump double
Layer straight tube.
Realize that above-mentioned purpose the technical solution of the utility model is, a kind of automobile-used high-performance abrasion-proof of concrete pump is double-deck straight
Abrasion-resistant hollow pipe is provided with pipe, including outer tube, the outer tube, the abrasion-resistant hollow pipe outer circumference surface is provided with shock-absorbing protecting layer,
The outer tube two ends, which are respectively equipped with flange, each flange, is machined with three groups of screwed holes, and each flange side surface is set
Have in protection layer, the abrasion-resistant hollow pipe and be machined with striped groove.
The outer tube is made by No. 45 or No. 20 steel.
The outer tube adds the casting of other alloying elements by high-chromium alloy and formed, mainly contain 18.6% metal ferrochrome,
Other rare metals composition such as carbon of 4.2% nickel, 5.5% molybdenum and 2.0-2.5%.
The shock-absorbing protecting layer material is PU foams.
The double-deck straight tube of the automobile-used high-performance abrasion-proof of a kind of concrete pump made using the technical solution of the utility model, this dress
Put with characteristics such as high intensity, shock resistance, high abrasions, strengthen 7 to 8 times compared to other like product wear-out periods, so as to reach
Operating cost, material, the effect that number of times lowers significantly is changed, improve service life and production efficiency, serve energy-saving ring
The effect of guarantor.

Embodiment
The utility model is specifically described below in conjunction with the accompanying drawings, as shown in Figure 1-2, a kind of automobile-used high property of concrete pump
Abrasion-resistant hollow pipe (2) is provided with energy Wear-resistant double-layered straight tube, including outer tube (1), the outer tube (1), the abrasion-resistant hollow pipe (2) is outside
Periphery is provided with shock-absorbing protecting layer (3), and outer tube (1) two ends, which are respectively equipped with flange (4), each flange (4), to be added
Work has three groups of screwed holes (5), and each flange (4) side surface is provided with protection layer (6), and the abrasion-resistant hollow pipe (2) is interior
It is machined with striped groove (7)；The outer tube (1) is made by No. 45 or No. 20 steel；The outer tube (1) adds it by high-chromium alloy
Its alloying element casting form, mainly contain 18.6% metal ferrochrome, 4.2% nickel, 5.5% molybdenum and 2.0-2.5% carbon etc. its
What his rare metal was constituted；Described shock-absorbing protecting layer (3) material is PU foams.
The characteristics of the present embodiment is that the abrasion-resistant hollow pipe in outer tube is in plant running, and abrasion-resistant hollow pipe is more wear-resisting,
Shock-absorbing protecting layer on abrasion-resistant hollow pipe outer circumference surface plays a part of damping, and the flange of outer tube two ends respectively plays the work of connection
With three groups of screwed holes on each flange are used for connecting, and the protection layer of each flange side surface is used for sealing, abrasion-resistant hollow
Volume striped groove is used for buffering in pipe, and the present apparatus has the characteristics such as high intensity, shock resistance, high abrasion, compared to other like products
Wear-out period strengthens 7 to 8 times, so as to reach operating cost, material, change the effect that number of times lowers significantly, improves and uses
Life-span and production efficiency, serve the effect of energy-conserving and environment-protective.
In the present embodiment, device material especially has superpower resistance in terms of delivering concrete, sandstone and ore
Mill is acted on, and is 5-8 times of existing potassium steel material.In to straight tube course of conveying in impact, the research process of abration position, obtain
At to straight tube flange inwall be most be hit, position most easy to wear.According to this result, specially docked when designing inner tube
Mouth flange inwall has carried out thickening processing, so as to reach the technical requirements of " easily mill position is most wear-resisting ".Inner tube is by accurate number
Equipment die sinking is controlled, is formed by machine centrifugal casting, and has carried out to flange most easy to wear the thickening more than 5mm
Processing, and being examined by strict detection device, ensured inherent material, size it is qualified.Outer tube flange is according to interior
The one-to-one design of size of pipe flange is by precision optical machinery processing and fabricating, and size is complete after inner tube flange is inserted in outer tube flange
It coincide seamless.The cost price of this bimetallic tube is only higher by 20% than domestic normal quenching straight tube, but is general in application aspect
5 to 6 times of logical quenching straight tube, that is to say, that can just complete the workload of 6 to 8 normal quenching straight tubes using 1 present apparatus.
Such a two-layer compound straight tube substantially reduces operation expense by contrast, has reached the purpose for saving material resources.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Some variations that personnel may make to some of which part embody principle of the present utility model, belong to the utility model
Protection domain within.
