Abstract
The invention discloses a conveying pipe for a light-weight concrete pump truck arm frame. The conveying pipe is characterized in that a layer of carbon fiber ropes with glue is uniformly and straightly wound on the outer surface of the conveying pipe of the concrete pump truck arm frame, then, a layer of carbon fiber ropes with glue is uniformly wound in the transverse direction, flanges arranged at the two ends of the conveying pipe are also simultaneously wound during the transverse winding, after the winding completion, the conveying pipe is placed into a baking oven with the temperature reaching 150 DEG C, and the heating baking is carried out for 5 minutes. The conveying pipe for the light-weight concrete pump truck arm frame processed and manufactured in such a way has the advantages that the impact-resistant and pressure-resistant intensity of a cast iron pipe fitting of the original concrete pump truck arm frame is improved, particularly, the anti-cracking performance is enhanced, the service life is prolonged, the economic benefits are improved, and the safety and the stability during the whole vehicle work operation process of the concrete pump truck are greatly improved.
Description
Technical field
The invention discloses a kind of light concrete pumping vehicle arm rack delivery pipe, particularly all kinds of concrete pump truck arm delivery pipe loss of weight and manufacture new technology.
Background technique
Along with developing by leaps and bounds of modernization project site construction technology, concrete mixer obtains a large amount of popularization and applications.Existing concrete pump truck arm delivery pipe is all weld one deck steel plate materials at cast iron tube outer surface, although solve the working life that concrete pump truck arm pipe explosion is hurted sb.'s feelings and extended concrete pump truck arm pipe, but cost is high, complex process, the flange connected between the mouth of pipe is fragile, fit the slurries oozed out at place between flange and pipe fitting and easily corrode the steel plate materials be wrapped in outside concrete pump truck arm pipe fitting, be wrapped in the weight that outer steel plate materials has also increased the weight of concrete pump truck arm pipe, directly have influence on the stability that the work of concrete mixer car load runs, working efficiency is all not very good.Although also have now and a kind ofly use glass fibre reinforced plastic material parcel concrete pump truck arm delivery pipe and by technology such as carbon fiber composite surface injection mouldings, though alleviate the weight of concrete pump truck arm straight tube, but strength deficiency easily makes delivery pipe burst after parcel, and cost is higher, use can not be popularized.For solving these problems above, spy have developed a kind of light concrete pumping vehicle arm rack delivery pipe of low cost, namely meets compressive strength, alleviates the weight of delivery pipe, solve again the problems such as delivery pipe easily bursts.
Summary of the invention
The concrete pump truck arm delivery pipe that technical problem to be solved by this invention there is provided a kind of low cost and manufacturing process is simple, durable, safety, integrity are good, overall weight is light.
The technological scheme that the present invention solves the employing of its technical problem is: on the outer surface of concrete pump truck arm delivery pipe, mucilage binding is wound around two-layer carbon fiber rope, namely at the first straight carbon fiber rope to being wound around one deck band glue uniformly of the outer surface of concrete pump truck arm delivery pipe, then one deck band glue carbon fiber rope is laterally wound around uniformly, also be together wound around at the flange being laterally wound around delivery pipe two ends simultaneously, the baking box that temperature reaches 150 DEG C is put into after being wound around, heated baking 5 minutes, so just produce technique simple, durable, safety, integrity is good, the concrete pump truck arm delivery pipe that overall weight is light.
The present invention has the advantage of the following aspects:
(1), improve shock resistance, compressive strength, alleviate the weight of pipe fitting;
(2), solve all kinds of pipe fitting resistance to compression value after wearing and tearing that is hit and reduce the problem of easily explosion;
(3), manufacturing process is easy, tightness and adhesiveness strong, extend working life, reduce cost;
(4), this technology is applicable to all kinds of pipe fittings of the material such as cast iron and ceramet;
The pipe fitting price that the pipe fitting that carbon fiber rope is wound around wraps up than steel plate materials is cheaply many, and it is higher than the pipe fitting intensity of glass fibre reinforced plastic material parcel, and manufacturing process is simple, cost is low, greatly improves stability when all kinds of cast iron and the work of ceramet pipe fitting run and Security.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of light concrete pumping vehicle arm rack cylinder iron pipe fitting medium cast iron bend pipe;
Fig. 2 is light concrete pumping vehicle arm rack cylinder iron pipe fitting medium cast iron bend pipe A-A sectional drawing;
In figure: 1, carbon fiber rope 2, flange.
Embodiment
Below for a kind of light concrete pumping vehicle arm rack cylinder iron bend pipe pipe fitting, 1 description doing into enforcement of the present invention by reference to the accompanying drawings.
The first step: artificial by epoxy resin glue uniform application at same cast iron outer surface of bent pipe with on the kraft board of homalographic, then the carbon fiber rope of tailoring by comparable size in advance directly to being attached on cardboard uniformly, and smear one deck epoxy resin glue uniformly again on carbon fiber rope;
Second step: manually by posting the cardboard of the carbon fiber rope of band epoxy resin glue directly to wrapping cast iron bend pipe, when epoxy resin glue does not parch, tear at outer field kraft board;
3rd: cast iron bend pipe is laterally put into rotatable special fixture, the metal trough of epoxy resin glue that had one to fill between carbon fiber rope and fixture, fixture clamp cast iron bend pipe rotate and drive carbon fiber rope time, carbon fiber rope necessarily passes the metal trough of epoxy resin glue, equipment rotarily drives the carbon fiber rope speckling with epoxy resin glue can the horizontal uniform carbon fiber rope being wound around one deck band epoxy resin glue at cast iron outer surface of bent pipe, and the flange at delivery pipe two ends is also together wound around simultaneously;
4th: put into the baking box that temperature reaches 150 DEG C after the carbon fiber rope on cast iron bend pipe surface has been wound around, heated baking 5 minutes, allows epoxy resin glue fully parch;
By above step, just produce simple process, durable, safety, integrity are good, overall weight
Light and shock resistance value and the high a kind of light concrete pumping vehicle arm rack delivery pipe of compressive strength.
The light concrete pumping vehicle arm rack bend pipe, straight tube and the Taper Pipe that produce with said method are while entirety alleviates the weight of concrete pump truck arm delivery pipe, also improve the cylinder iron pipe fitting shock resistance of original concrete pump truck arm, measuring body intensity, enhance anti-spalling especially, extend working life, improve economic benefit, more greatly improve the security and stability when work of concrete mixer car load runs.
