Device capable of walking freely in pipeline

Abstract

The invention relates to a device capable of walking freely in a pipeline. The device comprises a front walking mechanism and a rear walking mechanism. The front walking mechanism and the rear walking mechanism are the same in structure. The front walking mechanism and the rear walking mechanism are respectively composed of a servo motor, an outer sleeve, an inner sleeve, a walking telescopic arm and a fixed telescopic arm. Each outer sleeve is placed on the periphery of the corresponding inner sleeve. The walking telescopic arms and the fixed telescopic arms are selectively connected with the ends of the inner sleeves and the ends of the outer sleeves. Each servo motor drives the corresponding inner sleeve and the corresponding outer sleeve to make intermittent relative movement through a transmission mechanism. The front walking mechanism and the rear walking mechanism are connected through an electric push rod, and a walking motor used for driving the electric push rod to be telescopic is arranged in the rear walking mechanism. According to the device, the walking telescopic arms and the fixed telescopic arms make selective contact with the inner wall of the pipeline, due to the fact that the electric push rod is driven by the walking motor, the entire device can be driven to walk freely inside the pipeline, the device can replace manual work to conduct maintaining, overhauling and dredging operations of pipelines and pipe networks, the labor of workers is lightened, and dangerous accidents are avoided.

Description

technical field [0001] The present invention relates to a device that can freely walk in the pipeline, more specifically, it relates to a walking and fixed telescopic arm of the front and rear traveling mechanism that alternately contacts the inner wall of the pipeline and is driven by an electric push rod to move freely in the pipeline. A device that moves freely inside. Background technique [0002] The overhaul and maintenance of urban underground pipe networks and factory production pipe networks are generally done manually. For the urban underground pipe network, because it is in a sealed, humid and dark state for a long time, it is easy to generate harmful H 2 S, flammable and explosive CO, CH 4 etc. If workers enter the underground pipe network for operation, poisoning accidents and explosion accidents are very likely to occur. For the pipeline network of a production enterprise, since the pipeline network generally circulates corrosive, toxic, and flammable gases ...

Problems solved by technology

For the urban underground pipe network, because it is in a sealed, humid and dark state for a long time, it is easy to generate harmful H 2 S, flammable and explosive CO, CH 4 etc. If workers enter the underground pipe network for operation, poisoning accidents and explosion accidents are very likely to occur

For the pipeline network of a production enterprise, since the pipeline network generally circulates corrosive, toxic, and flammable gases or liquids, if manual access to the pipeline is used for cleaning or maintenance, it will cause harm to the physical and mental health of the staff.

[0003] With the development of electronic technology and automation technology, robots used to replace manual work in dangerous places are emerging. However, due to the special structure of pipelines and pipe networks, there is currently no effective mechanical device that can move freely in pipelines. Walking instead of manual maintenance, overhaul and dredging of pipelines and pipe networks
