Description

Technical Field

[0001] The utility model relates to the technical field of pipeline robots, in particular to a roller and a pipeline robot. Background Art

[0002] As a moving part used in a new type of driving system, rollers are increasingly used in the special robot industry, especially in the pipeline robot industry. Rollers enable special robots to move on special environments such as water surfaces, water, and silt and sand, and are a supplement to wheeled motion.

[0003] Since the drum needs to move on the water surface, mud and other environments, it must be lightweight, wear-resistant, and have certain strength. However, there are two existing solutions for drums. One is to use a non-metallic shell solution for lightweighting. This solution can make the drum lighter, but the wear resistance is very poor and the life is very short; the other is to use a full metal drum. This type of drum has a good life and strength, but because it is too heavy, the movement effect of this type of drum in the water surface and other environments is not good. The existing technology cannot solve the problem of taking both lightness and wear resistance into consideration at the same time. Utility Model Content

[0004] The main purpose of the utility model is to provide a roller, aiming to provide a lightweight, wear-resistant and high-strength roller.

[0005] In order to achieve the above-mentioned purpose, the roller proposed by the utility model comprises:

[0007] The wear-resistant part is made of metal and is arranged on the outer surface of the spiral blade.

[0008] Optionally, the wear-resistant parts are made of aluminum alloy, stainless steel or titanium alloy.

[0009] Optionally, the roller body is made of synthetic resin or nylon composite material.

[0010] Optionally, the wear-resistant part includes a connecting portion and a working portion, the connecting portion is embedded in the spiral blade, and the working portion is coated on a side surface of the spiral blade away from the outer peripheral wall of the drum body.

[0011] Optionally, the connection portion is provided with a plurality of injection holes, the plurality of injection holes are arranged at intervals along the extension direction of the wear-resistant part, and the injection holes are used for integrally injection-molding connection between the roller body and the connection portion.

[0012] Optionally, the width of the working portion is greater than the width of the connecting portion.

[0013] Optionally, the height of the connecting portion is the same as the height of the spiral blade.

[0014] Optionally, the drum further includes a connecting seat, which is made of metal and is embedded in the outer surface of the spiral blade by a rubber coating process. The wear-resistant part is overlapped with the connecting seat and is detachably connected.

[0015] Optionally, two wear-resistant parts are embedded in the outer surface of the spiral blade, and the two wear-resistant parts are arranged alternately at intervals.

[0016] The utility model also provides a pipeline robot, comprising the roller as described above.

[0017] The technical solution of the utility model is that the outer surface of the spiral blade located on the drum body is provided with a wear-resistant part. The drum body is made of non-metallic material, and the wear-resistant part is made of metal material.

The roller body 10 is made of non-metallic material. A spiral blade 11 is convexly provided on the outer peripheral wall of the roller body 10 . The wear-resistant part 30 is made of metal material. The wear-resistant part 30 is arranged on the outer surface of the spiral blade 11 .

[0029] In this embodiment, non-metallic materials generally have the characteristics of being lightweight, and metal materials generally have the characteristics of high hardness, high wear resistance, and high strength. The wear-resistant parts 30 made of metal are arranged on the outer surface of the spiral blades 11. When the drum 1 contacts the external environment, the wear-resistant parts 30 can be in abutment contact, that is, the wear-resistant parts 30 are in contact and friction with the ground in different environments. By utilizing the characteristics of the metal material, the structure of the wear-resistant parts 30 can be maintained to achieve long-life use; the large-volume structure of the drum body 10 is made of non-metallic material. By utilizing its light weight, the overall weight of the drum 1 can be reduced, and the overall lightweight of the drum 1 can be achieved.

[0030] Furthermore, the wear-resistant part 30 and the drum body 10 can be combined by integral injection molding. When the drum body 10 is injection molded, the wear-resistant part 30 is arranged as an insert at the position of the drum body 10 corresponding to the spiral blade 11, and then the wear-resistant part 30 can be combined to the position corresponding to the outer surface of the spiral blade 11 to achieve the combination of the two.

[0031] Furthermore, the wear-resistant part 30 completely covers the length of the spiral blade 11 in the extension direction, and thus the wear-resistant part 30 can overlap different positions of the spiral blade 11, thereby ensuring that the wear-resistant part 30 is in contact with the external environment for the entire spiral blade 11, thereby maintaining the overall integrity of the spiral blade 11.

[0032] The technical solution of the utility model is that the outer surface of the spiral blade 11 located on the drum body 10 is provided with a wear-resistant part 30. The drum body 10 is made of non-metallic material, and the wear-resistant part 30 is made of metal. When the drum 1 moves and contacts with the ground, mud surface, sand and other ground, the wear-resistant part 30 contacts and generates friction. The wear-resistant part 30 is made of metal material and has good strength and wear resistance, which can greatly improve the overall strength and wear resistance of the drum 1. The drum body 10 is made of non-metallic material, which reduces the overall weight of the drum 1 and achieves lightness.

[0033] In an embodiment of the present invention, the wear-resistant part 30 is made of aluminum alloy, stainless steel or titanium alloy.

[0034] In this embodiment, when the wear-resistant part 30 is made of aluminum alloy, the aluminum alloy has the characteristics of light weight, high strength, good sealing performance, corrosion resistance, good rigidity, and durability. The appearance and structure of the wear-resistant part 30 can be maintained under the use environment of the wear-resistant part 30, so that it has a long service life.

[0035] Furthermore, when the wear-resistant part 30 is made of stainless steel, stainless steel has the characteristics of corrosion resistance, good rigidity, and durability, and can maintain the appearance and structure of the wear-resistant part 30 under the use environment of the wear-resistant part 30, so that it has a long service life. Similarly, titanium alloy also has the characteristics of high strength, good sealing performance, corrosion resistance, and good rigidity, and the wear-resistant part 30 made of this material has a long service life.

[0036] In an embodiment of the present invention, the drum body 10 is made of synthetic resin or nylon composite material.

[0037] In this embodiment, when the roller body 10 is made of synthetic resin, preferably, the synthetic resin is styrene resin. Synthetic resin has good strength and toughness, and has high impact resistance. Its tensile strength and bending strength are relatively high, and it can withstand large static and dynamic loads. It has good fatigue resistance, that is, it can still maintain high strength and toughness under long-term deformation cycle loading, and is not easy to crack and break. In addition, it also has the characteristics of excellent molding performance and high surface aesthetics.

[0038] Furthermore, when the drum body 10 is made of a nylon composite material, the nylon composite material: nylon is a synthetic fiber with the characteristics of high strength, wear resistance, corrosion resistance, etc., and can be well adapted to the working environment of the drum body 10.

[0039] In one embodiment of the present invention, Figure 2 As shown, the wear-resistant part 30 includes a connecting portion 31 and a working portion 33 . The connecting portion 31 is embedded in the spiral blade 11 , and the working portion 33 is coated on a side surface of the spiral blade 11 away from the outer peripheral wall of the drum body 10 .

[0040] In this embodiment, the wear-resistant part 30 includes a connecting portion 31 and a working portion 33. The connecting portion 31 is embedded in the spiral blade 11, and the working portion 33 is covered on the side surface of the outer peripheral wall of the spiral blade 11 facing away from the drum body 10. The connecting portion 31 is embedded in the spiral blade 11 as a part connected to the spiral blade 11 to be tightly connected to the spiral blade 11, and the working portion 33 is a part that is in direct contact with the external environment, that is, the wear-resistant part 30 is in contact and friction with the ground in different environments, thereby realizing protection for the drum body 10 and the spiral blade 11.

[0041] In one embodiment of the present invention, Figure 2 As shown, the connection part 31 is provided with a plurality of injection holes 311 , which are arranged at intervals along the extension direction of the wear-resistant part 30 , and the injection holes 311 are used for integrally connecting the drum body 10 and the connection part 31 by injection molding.

[0042] In this embodiment, the connection part 31 is provided with a plurality of injection holes 311, and the plurality of injection holes 311 are arranged at intervals along the extension direction of the wear-resistant part 30, and the injection holes 311 are used for the roller body 10 to be connected with the connection part 31 by injection molding. The wear-resistant part 30 and the roller body 10 can be combined by injection molding. When the roller body 10 is injection molded, the injected glue is penetrated through the injection holes 311 and solidified in the injection holes 311 and the outer surface of the connection part 31, and then the connection part 31 can be arranged as an insert at the position of the roller body 10 corresponding to the spiral blade 11, and then the connection part 31 can be combined with the position corresponding to the outer surface of the spiral blade 11 to achieve the combination of the two.

[0043] In one embodiment of the present invention, Figure 2 As shown, the width of the working portion 33 is greater than the width of the connecting portion 31 .

[0044] In this embodiment, the width of the working portion 33 is greater than the width of the connecting portion 31. In this way, the working portion 33 can cover the outer surface of the spiral blade 11, and when the drum 1 moves and contacts the ground, muddy surface, sandy ground, etc., the wear-resistant part 30, as a connecting surface, contacts the ground and generates friction, thereby protecting the drum body 10 and the spiral blade 11.

[0045] In one embodiment of the present invention, Figure 2 As shown, the height of the connecting portion 31 is the same as the height of the spiral blade 11 .

[0046] In this embodiment, the height of the connecting portion 31 is the same as the height of the spiral blade 11. In this configuration, since the connecting portion 31 needs to be embedded in the spiral blade 11, the height of the connecting portion 31 is the same as the height of the spiral blade 11, which can ensure the embedding thickness of the connecting portion 31, and further ensure the tightness of the connection between the connecting portion 31 and the spiral blade 11, and ensure the connection stability between the connecting portion 31 and the spiral blade 11 and the stability of the working portion 33 during the working process.

[0047] In one embodiment of the utility model, the drum 1 also includes a connecting seat, which is made of metal and is embedded in the outer surface of the spiral blade 11 through a rubber coating process. The wear-resistant part 30 is overlapped with the connecting seat and is detachably connected.

[0048] In this embodiment, the drum 1 also includes a connection seat, which is made of metal. The connection seat is embedded in the outer surface of the spiral blade 11 through a rubber coating process. The wear-resistant part 30 overlaps with the connection seat and is detachably connected. In this way, the connection seat is first embedded in the spiral blade 11, and then the wear-resistant part 30 is detachably connected to the connection seat, so that the wear-resistant part 30 can be disassembled, replaced and repaired. The connection seat is also made of metal, so the connection strength is guaranteed by being made of the same metal material as the wear-resistant part 30. The detachable connection method can be a threaded connection, a snap connection, a key connection, etc., which is not limited here.

[0049] In one embodiment of the present invention, Figure 2 As shown, two wear-resistant parts 30 are embedded in the outer surface of the spiral blade 11, and the two wear-resistant parts 30 are alternately arranged.

[0050] In this embodiment, two wear-resistant parts 30 are embedded on the outer surface of the spiral blade 11, and the two wear-resistant parts 30 are arranged alternately. Such arrangement ensures that when there are two spiral blades 11, the wear-resistant parts 30 cover the outer surface of the drum body 10 and wrap the outer surface, which can greatly improve the overall strength and wear resistance of the drum 1.

[0051] The utility model also proposes a pipeline robot, which includes a roller 1. The specific structure of the roller 1 refers to the above embodiment. Since the pipeline robot adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0052] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
