Abstract
A dedicated elbow inner container for a double-layer wear-resistant concrete pump truck is provided with an arc elbow serving as a main body, the outside wall thickness of the arc elbow is larger than the inside wall thickness, the thickness on the outside wall is gradually reduced and continuously changed from the intermediate line position to two side positions, the arc elbow approaches an even hollow barrel in the two end surface positions of the arc elbow, and meanwhile, during the gradual whole thickness change process, the outside wall thickness ranges from 8 mm to 15 mm, and the inside wall thickness ranges from 4 mm to 7 mm. The dedicated elbow inner container for the double-layer wear-resistant concrete pump truck is simple in technology, convenient to machine, and easy to assemble, and can effectively improve the own service life.
Description
Technical field
The utility model relates to the concrete mixer accessory, is specially a kind of special-purpose bend pipe inner bag of double-deck abrasion-proof concrete pump truck that can be used for concrete pump truck arm.
Background technique
In the construction industry, often can use concrete mixer in modern times, as a critical function spare on the concrete mixer; The jib bend pipe of concrete mixer mainly is used for carrying medium for building, and it is to be made up of the bend pipe with two connection mouths, and the medium of conveying is mainly concrete; Be the hybrid type cream slurry type fluid of cement, grit, mortar, its viscosity is high, frictional force is big to tube wall frictional force, and because the flow velocity in fluid its outside in the bend position of bend pipe is greater than the flow velocity of curve inner side; Therefore; Bend outside serious wear in the jib bend pipe, so damaged rapidly, though the wearing and tearing of the inboard of bend are very slight; Also have to change, thereby caused sizable wasting of resources.
The model utility content
The technical problem that the utility model solved is to provide a kind of double-deck abrasion-proof concrete pump truck special-purpose bend pipe inner bag, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technological scheme to realize:
The special-purpose bend pipe inner bag of double-deck abrasion-proof concrete pump truck, its main body is a curve bend, the outboard tube wall thickness of said curve bend is greater than the inside tube wall thickness; And on the outboard tube wall, reduce gradually and be continuous variation to two side position pipe thicknesses from the medium line position, during to the both ends of the surface position of curve bend, curve bend levels off to an even hollow cylindrical shell; Simultaneously; In whole pipe thickness progressive formation, the outboard tube wall thickness remains on 8mm～15mm, and the inside tube wall thickness is at 4mm～7 mm.
In the utility model, the bend angle of curve bend is 6 ° ~ 90 °.
In the utility model, said inner bag preferably adopts high abrasion, multielement low chrome casting.
In the utility model, the internal diameter of said bend pipe inner bag is 120mm～160mm.
In the utility model, the external diameter of said bend pipe inner bag is 130mm～180mm.
Beneficial effect: the utility model is reasonable in design; Can effectively utilize the variation of tube wall to adapt to the impact that cream is starched fluid, the sidewall wear-out period of outer curve unanimity in accomplishing is when saving material; Be convenient for changing maintenance, can effectively reduce the operating cost of concrete mixer.

Fig. 1 is the schematic representation of the preferred embodiment one of the utility model.
Fig. 2 is the schematic representation of the preferred embodiment two of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment one referring to the special-purpose bend pipe inner bag of double-deck abrasion-proof concrete pump truck of Fig. 1; In the present embodiment; The bend angle of curve bend is 90 °; 1 place is that the outboard tube wall thickness at A-A tangent plane place is 14mm to curve bend in the neutral position, greater than the 5.5mm of inside tube wall thickness, and on the outboard tube wall from the medium line position to two side positions promptly along A-A, A

4Direction, pipe thickness reduce and when being endface position 2 places that are changed to curve bend continuously gradually, and it is the hollow cylindrical shell of 5.5mm that curve bend levels off to a wall thickness.
In another embodiment of Fig. 2, the bend angle of curve bend is 6 °, and its outer wall thickness is changed to 5mm by 10mm to two side positions from the medium line position successively.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; 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 variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
1. the special-purpose bend pipe inner bag of double-deck abrasion-proof concrete pump truck is characterized in that its main body is a curve bend; The outboard tube wall thickness of said curve bend is greater than the inside tube wall thickness; And on the outboard tube wall, reduce gradually and be continuous variation to two side position pipe thicknesses from the medium line position, during to the both ends of the surface position of curve bend, curve bend levels off to an even hollow cylindrical shell; Simultaneously; In whole pipe thickness progressive formation, the outboard tube wall thickness remains on 8mm～15mm, and the inside tube wall thickness is at 4mm～7 mm.
