Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline robots, and particularly relates to a spring-supported walking mechanism for a pipeline robot. Background Art
[0002] A pipeline robot is a mechatronic system that can automatically walk inside or outside a small pipeline, carry one or more sensors and operating machinery, and perform a series of pipeline operations under the remote control of a staff member or computer automatic control. Among them, the wheel-wall type pipeline robot is widely used. This type of robot drives the robot to move forward and backward by means of multiple mechanical arms with extendable walking wheels closely attached to the inner wall of the pipeline. However, the mechanical arms of the existing robots are in a linkage relationship and extend synchronously, which cannot ensure that the pipeline robot travels in the center of the pipeline, nor can it meet the usage requirements of pipelines with different sizes and irregular shapes. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the problems existing in the prior art, and provide a spring-supported walking mechanism for a pipeline robot. Each walking wheel is pulled by its own spring and independently expands, which can better support the pipeline robot to travel in the center of the pipeline, and can also meet the usage requirements of pipelines with different sizes and irregular shapes, and has a wide application range.
[0004] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0005] A spring-supported walking mechanism for a pipeline robot includes a connecting end cover, a certain number of wheel arms, walking wheels and tension springs. An articulated seat is arranged on the outer end face of the connecting end cover. The wheel arms are circumferentially and evenly distributed, one end of which is connected to the articulated seat through a hinge rod A, and the other end is connected to the walking wheel through a hinge rod B. A certain number of circumferentially and evenly distributed screw holes A are arranged on the side surface of the connecting end cover. A screw A is arranged in the screw hole A. A screw hole B is arranged on the wheel arm, and a screw B is arranged in the screw hole B. The two ends of the tension spring are respectively connected to the screw A and the screw B. The connecting end cover is installed at both ends of the pipeline robot main body. Under the action of the tension spring, the wheel arms expand outwards along the articulated seat. When in the pipeline, it is ensured that the walking wheels are closely attached to the inner wall of the pipeline.
[0006] Preferably, a threaded section is arranged on the side surface of the connecting end cover, and matching threaded sections are arranged at both ends of the pipeline robot main body, which is convenient for connection and installation.
[0007] Preferably, a main shaft is arranged in the middle of the outer end face of the connecting end cover.
[0008] Preferably, a pull-ring screw is arranged at the end of the main shaft, which is convenient for connecting a rope or other pipeline robots.
[0009] Preferably, the number of the wheel arms is three, and correspondingly, the numbers of the traveling wheels and the tension springs are also three respectively.
[0010] The advantages of the present utility model are as follows: each traveling wheel of the traveling mechanism of the present utility model is pulled by its respective spring and independently opens, which can better support the pipeline robot to travel in the center of the pipeline, and can also meet the usage requirements of pipelines with different sizes and irregular shapes, and has a wide application range.
