Abstract
The invention discloses a high-temperature quenching internal spiral straight pipe used for a concrete pump truck. The high-temperature quenching internal spiral straight pipe comprises a straight pipe body and ditches. The ditches are arranged on the inner wall of the straight pipe body. The thickness of each ditch ranges from 1.5 mm to 2 mm. A 45 carbon structure seamless steel pipe is selected as the straight pipe body. The ditches are formed in the manner that a numerical control broaching machine is positioned in the straight pipe body to slice the inner portion of the straight pipe body. The self-propelling-force of concrete products is increased in the conveying process when the high-temperature quenching internal spiral straight pipe is used, the straight pipe body and a bent pipe can form upward and forward propelling force in the conveying process, the work pressure of a conveying cylinder is further reduced, and therefore the abrasion resistance of the straight pipe body is improved, the service life of the straight pipe body is prolonged, the work pressure of the conveying cylinder is reduced, and the number of replacement times of the conveying cylinder is decreased.
Description
Technical field
The present invention relates to a kind of concrete pump automobile-used hot quenching internal spiral straight tube.
Background technique
Present domestic concrete mixer (drag, pump) carries straight tube mainly following several: 1. general material, single material, as adopted the straight tube of common Welded tube production, just can complete through simple welding production.Although have any intensity and toughness, because its wear resistance is poor, working life is about 5000-8000 cube, and replacing often, thus have impact on working efficiency, adds process cost, existing substantially superseded.2. adopt seamless steel steel pipe or No. 45 welded tubes through inwall quenching heat treatment, to increase its wear-resisting property, present quenching pipe can improve delivering concrete amount to about 2 ten thousand to 2.5 ten thousand cubes, utilizes widely with the economic and practical market that obtains.3. draw the external composite straight pipe of mouth, outer tube is common seamless steel pipe, inner sleeve is the interior pipe of high manganese steel or high speed steel material, the method wear-resisting property is higher, shelf life, product specification was changed quick, but does not have manufacturer due to domestic greatly about about 4 ten thousand to 4.5 ten thousand cubes, import price is higher, increases cost.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of concrete pump automobile-used hot quenching internal spiral straight tube, in use increase the self-propelled power of concrete product in conveying, make it in straight tube and bend pipe conveying, self form a kind of upwards propelling force forward, further minimizing is by the working pressure of carrying cylinder, thus the abrasion resistance of the straight tube that is improved and service time, reduce the working pressure of conveying cylinder and change number of times.
A kind of concrete pump automobile-used hot quenching internal spiral straight tube, comprise straight tube and groove, described groove is arranged on straight tube inwall, and described groove has 1.5-2mm, described straight tube selects No. 45 carbon knot seamless steel pipes, and groove is positioned at the inner slicing of straight tube with numerical control broaching machine to form.
Described straight tube inside is provided with wearing layer, and described wearing layer thickness is 3-5mm, and described straight tube inwall hardening machine obtains wearing layer through row inwall quenching heat treatment.
Described making method is: adopt common No. 45 carbon to tie seamless steel steel pipe after Length-fixing cutting, be made into corresponding length dimension, with numerical control broaching machine location production department dark 1.5-2mm spiral inner wall groove after inner wall surface inspection, and then inwall is allowed to form the thick wearing layer of 3-5mm with inwall hardening machine through row inwall quenching heat treatment.
Compared with prior art, the present invention has following beneficial effect:
The present invention in use increases the self-propelled power of concrete product in conveying, make it in straight tube and bend pipe conveying, self form a kind of upwards propelling force forward, further minimizing is by the working pressure of carrying cylinder, thus the abrasion resistance of the straight tube that is improved and service time, reduce the working pressure of conveying cylinder and change number of times.

Embodiment
Below in conjunction with embodiment, the present invention is described further.
Embodiment
As shown in Figure 1, a kind of concrete pump automobile-used hot quenching internal spiral straight tube, comprise straight tube 1 and groove 2, described groove 2 is arranged on straight tube 1 inwall, described groove 2 has 1.5-2mm, described straight tube 1 selects No. 45 carbon knot seamless steel pipes, and groove 2 is positioned at the inner slicing of straight tube 1 with numerical control broaching machine to form.
Described straight tube 1 inside is provided with wearing layer 3, and described wearing layer thickness is 3-5mm, and described straight tube 1 inwall hardening machine obtains wearing layer 3 through row inwall quenching heat treatment.
Described making method is: adopt common No. 45 carbon to tie seamless steel steel pipe after Length-fixing cutting, be made into corresponding length dimension, with numerical control broaching machine location production department dark 1.5-2mm spiral inner wall groove after inner wall surface inspection, and then inwall is allowed to form the thick wearing layer of 3-5mm with inwall hardening machine through row inwall quenching heat treatment.
No. 40 this very common steel pipes of carbon knot seamless steel pipe are mainly had the concrete straight tube of different mechanical properties and transportation performance by the present invention through device fabrication.
Its inside is made to have the screw thread wire of similar rifling through processing in straight tube, be delivered to after in pump truck straight pipe by conveying cylinder at concrete product, make its concrete product form the conveying that turns clockwise through straight tube internal thread rifling by the effect of screw thread rifling, thus minimizing straight tube inwall is to the surface friction drag of concrete product.Increase the self-propelled power of concrete product in conveying, make it in straight tube and bend pipe conveying, self form a kind of upwards propelling force forward, further minimizing is by the working pressure of carrying cylinder, thus the abrasion resistance of the straight tube that is improved and service time, reduce the working pressure of conveying cylinder and change number of times.
The present invention in use increases the self-propelled power of concrete product in conveying, make it in straight tube and bend pipe conveying, self form a kind of upwards propelling force forward, further minimizing is by the working pressure of carrying cylinder, thus the abrasion resistance of the straight tube that is improved and service time, reduce the working pressure of conveying cylinder and change number of times.
This transporting velocity of this Novel straight tube can promote every meter 0.12 second, conveying side amount on can promote 8000-10000 cube.Calculate 50 cubes of this New pipes of the reinforcement of concrete with 56 meters of pump trucks and save 336 seconds namely 5.6 minutes than common tube, 5.6 minutes is that 1200-1500 calculating can save 1.43 liters of diesel oil by pump truck diesel engine work running speed, within 1 year, can save 28.6 liters of diesel oil by every platform work 1000 cubes of calculating.Calculate by often liter of diesel oil 5.81 yuan and can save 166.16 yuan every year.Conveying side's amount can for saving annual 87 pipes by the annual 1000 cubes of calculating of every platform, and by this kind of New pipe price 1 year needs 143980 yuan, common tube price needs 160000 yuan/root, can save 16020 yuan on year-on-year basis.Add up to 16186.6 yuan, other are negligible.
The foregoing is only some embodiments of the present invention, do not limit the present invention, the technological scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, all drop in protection scope of the present invention.
