Description

Technical Field

[0001] The utility model relates to the field of hose manufacturing, in particular to a vacuum transport hose. Background Art

[0002] In the logistics and transportation industry, vacuum hoses are important components of vacuum lifting equipment such as suction cranes, balance cranes, transfer vehicles, and transport vehicles. The vacuum hose moves above the goods, and a negative pressure vacuum is generated inside the vacuum lifting equipment. The vacuum hose performs vacuum suction, and the suction cup at the end of the tube firmly sucks the goods. Then the vacuum hose shortens and lifts the goods to a predetermined position at a high place. The goods are unloaded after the vacuum is removed. It is easy to understand that during the process of suction, lifting, and transfer, the vacuum hose needs to be frequently extended and retracted and acted upon by gravity to drive the goods to a high place or move to a low place to absorb the goods. High elasticity is an important performance of the vacuum hose.

[0003] Since most existing vacuum hoses are made by extrusion molding, due to the technical limitations of the extruder and the extrusion process, the wall of the extruded pipe is thicker, and the thick-walled pipe will have a greater impact on the expansion and contraction efficiency. In addition, due to frequent expansion and contraction, the resilience of the vacuum hose is also particularly important, and the resilience of the thick-walled pipe also needs to be further improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model aims to provide a vacuum handling hose, which can solve the problem of insufficient elasticity and resilience of the prior vacuum hose.

[0005] The utility model is realized by the following technical solutions:

[0006] A vacuum handling hose comprises: an elastic metal wire, which is a spiral structure; a tubular layer, which comprises: a fiber cloth layer; the tubular layer is wound around the elastic metal wire; the tubular layer and the elastic metal wire are bonded and fixed to form a tubular structure; and a winding, which is tightly wound around the tubular layer along the extension direction of the elastic metal wire so that the tubular layer and the elastic metal wire are tightly fitted.

[0007] Furthermore, the tubular material layer further comprises: a rubber layer or a silicone layer calendered on the front and back surfaces of the fiber cloth layer.

[0008] Furthermore, the elastic metal wire is a spiral steel wire spirally wound on a tubular mold and shaped.

[0009] Furthermore, the steel wire is coated with a rubber layer.

[0010] Furthermore, the adhesive layer is rubber or silicone.

[0011] Furthermore, the rubber layer is chloroprene rubber or synthetic rubber.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] During the production process, the elastic metal wire is spirally wound on a tubular mold to form a shape. The tube layer is first made into a coil with a sufficiently thin thickness, and then the coil is cut into strips of appropriate specifications. The strips are wrapped around the mold, that is, the tube layer is tightly wrapped around the spiral elastic metal wire, and the two are tightly bonded to form a tubular structure; then, the tube layer and the elastic metal wire are tightly fitted through the tight winding of the wire.

[0014] Compared with the hose made by the extrusion molding process in the past, the utility model adopts the winding shaping method. In this way, the pipe layer can be made thin enough first, and then it can be tightly wrapped on the spiral elastic metal wire. After the two are tightly fitted, a vacuum hose with a thin enough wall can be made, thereby improving the elasticity of the vacuum hose. In addition, the spiral elastic metal wire can also provide good resilience for the hose and improve the telescopic effect. At the same time, the method of fitting the elastic metal wire to the inner wall of the pipe is more convenient and quick to manufacture, and the integrity of the pipe layer is better than the embedded steel wire fixation in the prior art.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] The utility model discloses a vacuum handling hose, which is particularly used for vacuum lifting equipment such as a suction lifting machine, a balance crane, a transfer vehicle, and a transport vehicle. Figure 1-Figure 2 The vacuum handling hose comprises: an elastic metal wire 10, a tubular material layer 20 and a winding wire 30. The elastic metal wire 10 is a spiral structure; the tubular material layer 20 comprises a fiber cloth layer, and the tubular material layer 20 is wound and wrapped on the elastic metal wire 10; the tubular material layer 20 and the elastic metal wire 10 are bonded and fixed to form a tubular structure; the winding wire 30 is tightly wound on the tubular material layer 20 along the extension direction of the elastic metal wire 10, so that the tubular material layer 20 and the elastic metal wire 10 are tightly fitted.

[0023] Preferably, the elastic metal wire 10 is an elastic steel wire, which is spirally wound on a tubular mold for shaping. Further preferably, the steel wire is also coated with a rubber layer to improve its adhesion to the tubular layer 20. The rubber layer can be rubber or silicone.

[0024] Preferably, the pipe layer 20 further comprises: a rubber layer or a silicone layer calendered on the front and back surfaces of the fiber cloth layer; further, the rubber layer can be made of chloroprene rubber or synthetic rubber. The vacuum handling hose provided by the utility model has good chemical resistance, oil resistance, water resistance, and good heat resistance.

[0025] During production, the elastic metal wire 10 is coated with rubber, coated with adhesive, and spirally wound on a tubular mold at a certain interval to shape it. The fiber cloth is rolled on both sides of the rubber or silicone material to make a coil with a sufficiently thin thickness, and then the coil is cut into strips of suitable specifications, and then the strips are wrapped around the mold, that is, the tubular layer 20 is tightly wrapped on the spiral elastic metal wire 10, and the two are tightly bonded to form a tubular structure, and then vulcanized to make the elastic metal wire 10 and the tubular layer 20 tightly combined together; finally, through the tight winding of the winding wire 30, the tubular layer 20 and the elastic metal wire 10 are further tightly fitted (from Figure 1 As can be seen in the figure, since the tubular layer 20 is made of a flexible material and the elastic metal wire 10 is made of a rigid material, after being tightly wrapped, protrusions of the elastic metal wire 10 will be embossed on the outer wall of the tubular layer 20).

[0026] Compared with the hose made by the extrusion molding process in the past, the utility model adopts the winding shaping method. In this way, the tube layer 20 can be made into a sufficiently thin thickness first, and then it can be tightly wrapped on the spiral elastic metal wire 10. After the two are tightly fitted, a vacuum hose with a sufficiently thin tube wall can be made, thereby improving the elasticity of the vacuum hose. In addition, the spiral elastic metal wire 10 can also provide good resilience for the hose and improve the telescopic effect. At the same time, the method of fitting the elastic metal wire 10 to the inner wall of the pipe is more convenient and quick to manufacture compared to the steel wire embedded fixation in the prior art, and the integrity of the tube layer 20 is better.

[0027] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
