Abstract
The utility model discloses a special elbow pipe for a double-layer wear-resisting concrete pump truck. The elbow pipe comprises an elbow pipe inner pipe and a protective sleeve, wherein the protective sleeve is formed through punching of steel materials and comprises an inner sleeve and an outer sleeve, the inner sleeve and the outer sleeve are respectively used for packing the inner side of the elbow pipe and the outer side of the elbow pipe, simultaneously, the inner sleeve and the outer sleeve of the elbow pipe are welded on the side of the elbow pipe, the inner surface of a cylinder body consisting of the inner sleeve and the outer sleeve of the elbow pipe is closely attached to the outer surface of the inner pipe of the elbow pipe, at the same time, port connecting flanges are further arranged on the two sides of inner pipe of the elbow pipe, the port connecting flanges are connected with the protective sleeve in a welding mode, and flange inner sleeves are further arranged on the inner sides of the port connecting flanges. The elbow pipe is simple in process, convenient to process, and easy to assemble, and can effectively prolong the service life.
Description
Technical field
The utility model relates to the concrete pump truck arm bend pipe, is specially the special-purpose bend pipe of a kind of double-layer wear-resistant concrete mixer.
Background technology
In the modern architecture industry; often can use concrete mixer; as a critical function spare on the concrete mixer; the jib bend pipe of concrete mixer is mainly used to carry medium for building; it is to be made of the bend pipe with two connectors, and the medium of conveying is mainly concrete, i.e. the mixed type cream of cement, grit, mortar slurry class fluid; its viscosity is high, frictional force is large to tube wall frictional force, so jib bend pipe medial surface is very easy to wearing and tearing.And mostly traditional bend pipe is to make and cylinder iron makes, so that bend pipe is when work, sizable impact force and frictional force in the delivering concrete process have been born, when equipment is easy to wear, the high temperature that sidewall produces also causes Tube Bending Deformation and even explosion to hurt innocent persons easily, and the cast iron bend pipe that replacing jib bend pipe is used also comparatively takes time and effort, and easily affects programming.
The utility model content
The technical problem that the utility model solves is to provide a kind of double-layer wear-resistant concrete mixer special-purpose bend pipe, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The special-purpose bend pipe of double-layer wear-resistant concrete mixer, comprise bend pipe inner tube and sheath, wherein, described sheath is by the steel plate materials punch forming, comprise inner sleeve and overcoat, inner sleeve and overcoat are respectively applied to wrap up bend pipe inboard and the bend pipe outside, simultaneously, the inner sleeve of bend pipe be enclosed within the other seam of bend pipe side outward, and the cylinder inner surface that forms of bend pipe inner sleeve and bend pipe overcoat and the intimate applying of bend pipe inner tube; Simultaneously also be provided with the port adpting flange in the both sides of bend pipe inner tube, the port adpting flange is connected with sheath by welding manner.
In the utility model, port adpting flange inboard also is provided with the flange inner sleeve, and described flange inner sleeve is the cylindricality hollow pipe fitting of an applying port adpting flange inner surface.
Beneficial effect: the utility model utilizes the shock resistance of steel plate materials and withstand voltage.Heat-resistant quality can bear inner cast iron bend pipe when work stamping press and heat-resisting ability get a promotion, simultaneously, adopt the inner sleeve of mode bridge piece of the other seam of side and overcoat can prevent effectively that again the bend pipe extrados sheath that causes that is hit from peeling off, thereby can effectively reduce the equipment use cost, improve its application life.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to the special-purpose bend pipe of the double-layer wear-resistant concrete mixer of Fig. 1, in the present embodiment, comprise bend pipe inner tube 4 and sheath, wherein sheath comprises inner sleeve 3 and overcoat 2, between connect by welding manner, simultaneously, also be provided with flange inner sleeve 6 in the both sides of bend pipe inner tube 4, flange inner sleeve 6 external stability ports having adpting flanges 5.Simultaneously, port adpting flange 5 is by welding manner and inner sleeve 3 and overcoat 2 seam.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
