Embodiment 1

[0034] figure 2 The cross-sectional schematic diagram of the five-shaped arm frame provided for the embodiment of the present invention, as figure 1 As shown, the pentagonal jib provided by the embodiment of the present invention includes: the jib body 100, the jib body 100 is formed by bending a sheet, and the two ends of the bent sheet are connected by welding, and the welding formed by welding The slot 200 is located on the top plate of the boom body 100 .

[0035] Specifically, the jib body 100 includes a first side plate 110 and a second side plate 120, the first side plate 110 and the second side plate 120 are parallel to each other, the lower end of the first side plate 110 and the lower end of the second side plate 120 pass through The two inclined bottom plates 150 are connected, the upper end of the first side plate 110 is connected with the first top plate 130, the upper end of the second side plate 120 is connected with the second top plate 140, the first top pla...

Embodiment 2

[0040] An embodiment of the present invention provides a wet spray machine. The wet spray machine provided by the embodiment of the present invention includes the pentagonal arm provided in the first embodiment.

[0041] Specifically, the spray humidifier provided by the embodiment of the present invention includes at least two pentagonal arm frames provided in Embodiment 1. As shown in 3, the cross-sectional shapes of adjacent pentagonal arm frames are the same but different in size; the cross-sectional size One end of the smaller pentagonal arm extends into the larger pentagonal arm, the other end is located outside, and the outer end is provided with a nozzle, two pentagonal arms form a telescopic arm, two The gap between the pentagonal arms is provided with a middle slider 300, and the middle slider 300 prevents mutual friction between the two pentagonal arms.

[0042] In the process of using the wet spray machine, the telescopic arm is extended or contracted according to ...

Embodiment 3

[0044] An embodiment of the present invention provides a method for manufacturing a polygonal boom.

[0045] The polygonal arm frame manufacturing method provided by the embodiment of the present invention is used to manufacture the above-mentioned pentagonal arm frame, comprising: bending the plate into a polygon, and the interface of the plate is located on the side of the polygon; welding.

[0046] Specifically, use a bending machine to bend a plate into a pentagon, and the side plates at both ends of the bent plate can be spliced ​​into a pentagonal side, and then, the two ends of the bent plate are welded Connected in a way to form a pentagonal arm.

[0047] Further, the two ends of the sheet are bent first, and then the middle of the sheet is bent.

[0048] Specifically, first use the bending knife 400 to bend the first top plate 130 and the first side plate 110 at one end of the plate, and bend the second top plate 140 and the second side plate 120 at the other end of...

Abstract

The invention provides a pentagonal arm frame, a wet spraying machine, and a manufacturing method of a polygonal arm frame, and relates to the technical field of engineering machines. The pentagonal arm frame comprises an arm frame body which is formed by bending of a plate, the two ends of the bent plate are connected in a welded mode, and a welded joint formed by welding is located on a top plate of the arm frame body. According to the pentagonal arm frame, the technical problems that in the prior art, the section size of the pentagonal arm frame is difficult to ensure due to the fact that welding heat input is large, and consequently, the two side faces are prone to shrinkage deformation are relieved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a method for manufacturing a pentagonal boom, a wet spray machine and a polygonal boom. Background technique [0002] Most construction machinery uses booms with quadrilateral cross-sections. Relatively speaking, booms with pentagonal cross-sections are more rigid than quadrilateral booms. For some construction machinery booms that require higher rigidity, some are changed from quadrilateral to The pentagon, such as the concrete wet spraying machine, needs to move the boom continuously and greatly during construction. To achieve where the nozzle points and hits, the entire boom needs to have good rigidity. Many wet spraying machines are now large. The arms are all pentagonal, such as figure 1 As shown, most of the existing pentagonal jibs are tailor-welded from two bent parts, and the two welds 200 are generally on the less stressed parts of the two sides of the pe...
