A chassis component and pipeline robot

Abstract

This invention discloses a chassis component and a pipeline robot. The chassis component includes a chassis, a pressure booster, and two traveling members. The chassis is arranged along the front-to-back direction, and the two traveling members are arranged on both sides of the chassis along the front-to-back direction. The pressure booster is arranged on the chassis along the front-to-back direction. The upper end of the pressure booster is a flat surface, and its lower end protrudes downward in the front-to-back direction as an arc surface. The pressure booster moves in the opposite direction along the front-to-back direction with the chassis in the water flow and is subjected to downward pressure by the water flow. In this way, the pressure booster can apply a downward force to the chassis component under the action of the water flow, thereby improving the grip of the chassis component's traveling members. This makes the chassis component move stably under the impact of the water flow.

Description

Technical Field

[0001] This invention belongs to the field of pipeline robots, and particularly relates to a chassis component and a pipeline robot. Background Technology

[0002] For underwater pipeline robots, their grip on the bottom of the pipeline is mainly based on their own weight (minus the buoyancy they experience). When the water inside the pipeline is flowing, the pipeline robot is easily affected by the current and drifts with the current due to insufficient grip, which leads to poor walking stability. Currently, the main way to improve the grip of pipeline robots in water flow is to increase their own weight. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a chassis component with a simple structure that can rely on water flow to provide downforce and thus improve grip in water flow.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A chassis component includes a chassis, a pressurizing component, and two traveling components. The chassis is arranged along the front-rear direction, and the two traveling components are arranged on both sides of the chassis along the front-rear direction. The pressurizing component is arranged on the chassis along the front-rear direction. The upper end of the pressurizing component is a flat surface, and its lower end protrudes downward in the front-rear direction as an arc surface. The pressurizing component moves in the opposite direction along the front-rear direction with the chassis in the water flow and is subjected to downward pressure by the water flow.

[0005] The beneficial effect of the above technical solution is that the pressurizing component can apply a downward force to the chassis component under the action of water flow, thereby improving the grip of the chassis component's steering component, thus making the chassis component move stably under the impact of water flow.

[0006] The traveling component described in the above technical solution is a track wheel or a wheel.

[0007] The beneficial effect of the above technical solution is that its structure is simple.

[0008] The above technical solution includes two booster components, which are respectively located on both sides of the chassis.

[0009] The beneficial effect of the above technical solution is that by setting a supercharger on each side of the chassis, the balance of the two sides of the chassis is well achieved.

[0010] In the above technical solution, the booster component has multiple first connecting ears spaced apart along the front-rear direction on the middle part of the side near the chassis. Each first connecting ear has a first through hole that extends from left to right. Both sides of the chassis have multiple second connecting ears arranged along the front-rear direction. Each second connecting ear has a second through hole that extends from left to right. The multiple first connecting ears and multiple second connecting ears on the same side correspond one-to-one, are aligned with each other, and are bolted together.

[0011] The advantages of the above technical solution are that it has a simple structure and makes it easier to install and remove the supercharger on the chassis.

[0012] The pressurizing component described in the above technical solution is provided with two first connecting ears.

[0013] The advantages of the above technical solution are: its structure is simple, and the two first connecting ears and two second connecting ears can be used to stably install the supercharger on the chassis.

[0014] The pressurizing component described in the above technical solution is hollow inside, and its side wall is provided with a sand injection port communicating with its interior, and a cover is provided at the sand injection port.

[0015] The beneficial effect of the above technical solution is that by filling the supercharger with sand, the weight of the entire chassis component can be increased, thereby increasing its grip.

[0016] The pressure boosting component described in the above technical solution is a plastic component.

[0017] The advantages of the above technical solution are that it has a simple structure and low cost.

[0018] In the above technical solution, the lower end of the chassis protrudes downward in an arc shape in the front-to-back direction.

[0019] The beneficial effect of the above technical solution is that it allows the fluid to exert downward pressure on the chassis when it flows over it, which can further improve the grip of the chassis components.

[0020] The second objective of this invention is to provide a pipeline robot with a simple structure and good grip in water flow.

[0021] To achieve the above objectives, the technical solution of the present invention is as follows: a pipeline robot, comprising the chassis component as described above.

[0022] The advantages of the above technical solution are: it has a simple structure, good grip in water flow, and good driving stability. Attached Figure Description

Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0030] Example 1

[0031] like Figure 1 As shown, this embodiment provides a chassis component, including a chassis 1, a pressurizing component 2, and two traveling members 3. The chassis 1 is arranged along the front-rear direction, and the two traveling members 3 are arranged on both sides of the chassis 1 along the front-rear direction. The pressurizing component 2 is arranged on the chassis 1 along the front-rear direction. The upper end of the pressurizing component 2 is a flat surface, and its lower end protrudes downward in the front-rear direction as an arc surface. The pressurizing component 2 moves in the opposite direction along the front-rear direction with the chassis 1 in the water flow and is subjected to downward pressure by the water flow (the principle is similar to the upward bulging of an airplane wing, where the airflow exerts an upward buoyancy on it. However, in this embodiment, the pressurizing component protrudes downward, so the force exerted by the water flow is downward). In this way, the pressurizing component can exert a downward force on the chassis component under the action of the water flow, thereby improving the grip of the chassis component's traveling members. This makes the chassis component move stably under the impact of the water flow.

[0032] The traveling component 3 in the above technical solution is a track wheel or a wheel, which has a simple structure.

[0033] like Figure 2 As shown, the above technical solution provides two booster components 2, which are respectively located on both sides of the chassis 1. By providing one booster component on each side of the chassis, the chassis achieves good balance on both sides.

[0034] like Figure 3 and Figure 4 As shown in the above technical solution, the booster component 2 is provided with a plurality of first connecting ears 21 at intervals along the front-back direction on the middle part of the side near the chassis 1. The first connecting ears 21 are provided with a first through hole 22 that passes through from left to right. The chassis 1 is provided with a plurality of second connecting ears 11 along the front-back direction on both sides. The second connecting ears 11 are provided with a second through hole 12 that passes through from left to right. The plurality of first connecting ears 21 and the plurality of second connecting ears 11 on the same side correspond one-to-one and are aligned with each other and bolted together (that is, the first through hole 22 on the corresponding first connecting ear 21 and the second through hole 12 on the corresponding second connecting ear 11 are aligned and a bolt 41 is inserted, and at least one nut 42 is threadedly connected to the threaded end of the bolt 41 to install the booster component on the chassis 1). Its structure is simple and makes it more convenient to disassemble and assemble the booster component on the chassis.

[0035] The booster component 2 described in the above technical solution is provided with two first connecting ears 21. Its structure is simple, and the two first connecting ears and two second connecting ears can be used to stably install the booster component on the chassis.

[0036] In the above technical solution, the booster component 2 is hollow inside, and its side wall is provided with a sand injection port 23 communicating with its interior. A cover 24 is provided at the sand injection port 23. In this way, the weight of the entire chassis component can be increased by filling the booster component with sand, thereby increasing its grip. The sand injection port is an outwardly protruding tubular interface with external threads on its outer side wall. The cover can be a groove-shaped cover with internal threads on its inner wall. The cover can be threaded onto the sand injection port. Sand can be pre-filled into the booster component during operation, and after use, it can be removed from the chassis and the sand inside can be emptied.

[0037] The booster component 2 described in the above technical solution is a plastic component, which has a simple structure and low cost.

[0038] See details Figure 4 In the above technical solution, the lower end of the chassis 1 protrudes downward in the front-rear direction as an arc surface, so that when the fluid flows over the chassis, it can also apply downward pressure to the chassis, which can further improve the grip of the chassis components.

[0039] like Figure 5As shown, the thickness of the booster gradually decreases from the side closer to the chassis 1 to the side farther away from the chassis. This reduces the resistance of the chassis components when traveling in water because the water flow is guided outward after passing under the booster.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
