Description

Discharge pipe for concrete pump

Technical field

The utility model relates to the discharge pipe fields of concrete pump, and in particular, to a kind of going out for concrete pump Pipe material.

Background technique

With the rise of modern industry, have become the master of construction industry construction using concrete as the construction mode of main material One of construct, very big ratio is occupied in various engineering constructions construction, therefore but also the development of concreting machinery passes through It does not wane long, and has more and more fiery situation.

The discharge port (such as discharge port of tubular pile concrete pump) of existing concrete pump is generally connected with discharge nozzle in turn Road and concrete conveyance long tube, during actual use, the discharge port of this concrete pump is not the horizontal (method of discharge port Blue end face and horizontal plane have 82.5 ° or so of angle), in order to guarantee that concrete conveyance long tube and subsequent pipeline are in same water Plane is not 180 ° of straight angles for connecting but having 172.5 ° or so between discharge pipe and concrete conveyance long tube, Therefore the flange for connecting discharge pipe on existing concrete conveyance long tube is relative to concrete conveyance long tube itself Inclined (angle between the end face and concrete conveyance long tube of flange with 82.5 ° or so), to guarantee concrete conveyance Long tube and subsequent pipeline are in same level, but since concrete conveyance long tube itself is longer, above-mentioned inclined flange is substantially The installation difficulty (concrete conveyance long tube needs to rotate contraposition during installation) of concrete conveyance long tube is increased, and due to going out With 172.5 ° or so of angle, (for pumped (conveying) medium, camber means to hinder between pipe material and concrete conveyance long tube Power has resistance that will generate and is seriously worn, so camber is present in where which section will wear aggravation, coagulation in the construction process Soil is present in pipeline, concrete conveyance long tube replaced compared with discharge pipe with clear up it is more troublesome with it is inconvenient), actually coagulation Soil conveying long tube close to above-mentioned inclined flange inner surface to concrete by producing obstructions, therefore discharge pipe and mix The inner surface close to above-mentioned inclined flange of solidifying soil conveying long tube is very easy to abrasion, even if existing discharge pipe inner surface Using the wear-resisting Welding of heap, (the wear-resisting weldering of heap can form step in discharge pipe inner surface or lead to discharge pipe inner surface very It is coarse, increase resistance), discharge pipe be still prone to wear (pumping C60 and the above high grade concrete when, tubular pile concrete Continuous work service life 10 days or so discharge pipes of pump will gall, and seriously delay production).

Summary of the invention

The purpose of the utility model is to provide it is a kind of be easily installed maintenance, long service life, high reliablity for coagulation The discharge pipe of soil pump.

To achieve the goals above, the utility model provides a kind of discharge pipe for concrete pump, the discharge nozzle Road includes that first pipe, ceramic conveying member, first flange and second flange, the first flange are used for and the concrete pump Discharge port connection, the second flange with concrete conveyance long tube for connecting, the first flange and the second flange one One is arranged in correspondence at the both ends of the first pipe, and the ceramics conveying member is arranged in the first pipe, and described The inner surface of ceramic conveying member with concrete for contacting to form the transfer passage for delivering concrete.

Further, the ceramic conveying member is earthenware duct or potsherd group, and the potsherd group includes multiple edges The potsherd that circumferencial direction is arranged successively.

Further, the centre bore of the first flange has first annular table top, and the centre bore of the second flange has There is the second circular table, the both ends of the first pipe are connected to the first annular table top and second annular table respectively Face, and the end face at the both ends of the earthenware duct is connected to the first annular table top and second circular table respectively.

Further, the ceramic conveying member is made of silicon carbide ceramics.

Further, the outer surface of the ceramic conveying member is adhered to the inner surface of the first pipe by ceramic glue.

Further, the ceramic conveying member with a thickness of 7~20 millimeters.
