Description

Pump sending cement pole spout connects

Technical Field

The invention belongs to the technical field of pumping cement electric pole pouring, and particularly relates to a nozzle joint of a pumping cement electric pole.

Background

With the rapid development of the construction technology of modern engineering construction sites, the demand of the cement telegraph poles is large, the cement telegraph poles are small in diameter but long in length, cement is poured from the inside through a pressure pump when the cement is poured, a nozzle of the cement telegraph pole is subjected to high-pressure high-speed abrasion of concrete slurry during the pouring of the cement telegraph poles, particularly, the joint parts have pressure from all aspects when the slurry is sprayed, and the abrasion rate is higher.

At present, cement pouring pipelines all over the country adopt a cast wear-resistant steel manufacturing process, and due to the fact that material media are hard and large in particles and mechanical movement is added, a stirring knife is easy to wear, one-time pouring pipeline or joint replacement can be caused, the machine halt maintenance time is shortened, and the maintenance cost is increased; and a safety accident may occur.

Therefore, there is a great need for a nozzle joint for pumping concrete poles to solve the problems existing in the prior art.

Disclosure of Invention

The pump truck stirring cutter solves the problems that in the prior art, a pump truck stirring cutter is complex in structure, complex in installation, troublesome in maintenance and replacement, time-wasting, labor intensity-increasing and easy to wear and has a short service life.

In order to solve the technical problem, the invention discloses a nozzle joint of a pumping cement electric pole, which adopts the following technical scheme:

the utility model provides a pump sending cement pole spout connects, both ends are respectively for connecting in injection apparatus's link, passageway and the spout end that sprays cement, its characterized in that, include inside lining porcelain ring, seamless steel pipe and the outer lining porcelain ring that sets gradually from inside to outside, paste through first high strength viscose layer and second high strength viscose layer respectively between inside lining porcelain ring, seamless steel pipe and the outer lining porcelain ring, the inside welding of connecting end has the inside lining steel ring of seamless steel pipe, inside lining steel ring thickness equals inside lining porcelain ring is the thickness on second high strength viscose layer in addition.

Preferably, the length of the upper semicircular ring at the nozzle end is smaller than that of the lower semicircular ring, and the radius of the tail end of the lower semicircular ring is gradually reduced.

Preferably, the tail part of the lower semicircular ring is provided with an extension part, and an inner lining ceramic ring, an outer lining ceramic ring and a ceramic ring are respectively stuck to the upper side, the lower side and the outer side of the seamless steel pipe in the extension part.

Compared with the prior art, the invention has the following beneficial effects: the invention adopts the high-strength ceramic sheet or the steel ceramic composite sheet as the anti-abrasion and anti-corrosion part, thereby having low cost and long service life; simple and practical structure, simple manufacture, low cost and good effect. Wear-resisting anticorrosive, practice thrift the maintenance cost, it is more convenient to use.
