Accurate butt-joint device for automatic clamping of pipeline and movable butt-joint device

Abstract

The invention discloses an accurate butt-joint device for automatic clamping of a pipeline and a movable butt-joint device. The accurate butt-joint device comprises a rack, a clamping mechanism, a pipeline joint moving mechanism and a pipeline joint head, wherein the clamping mechanism and the pipeline joint moving mechanism are arranged on the rack; the clamping mechanism is positioned and a moving pipeline butt-joint at the moving end is clamped; the pipeline joint moving mechanism drives the pipeline butt-joint head to horizontally move relative to the pipeline. The movable butt-joint device comprises a movable pipeline butt-joint, a positioning spring, a movable plate, a universal ball, an elastic component and a base, wherein the clamping mechanism is positioned and clamped after the movable pipeline butt-joint is in position, a pipeline butt-joint is pushed by a pushing mechanism and is connected with the movable pipeline butt-joint; and the movable pipeline butt-joint is driven by a movable plate to move to a correct position under the common function of the clamping mechanism and an elastic component when the movable pipeline butt-joint is positioned. The accurate butt-joint device has the advantages of high positioning accuracy and reliability, simple structure, low cost and easiness for maintenance.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection, and in particular relates to a pipeline automatic clamping and precise docking device and a mobile docking device. Background technique [0002] In large-span mobile equipment, especially in heavy chemical, sugar, pharmaceutical, metallurgical and other equipment that needs to be moved and repeatedly positioned, the automatic, reliable and accurate docking of pipes and cables on the mobile equipment with the fixed end is very important for the realization process. Automation and improved efficiency, safety and reliability are of great significance. At present, for the connection of large-span mobile work equipment and fixed-location pipelines and cables, manual connection, spherical or conical mechanical guidance positioning, video control positioning, and position sensor positioning are generally used. Manual connection has low efficiency, poor reliability, and difficult to guarante...

AI Technical Summary

Problems solved by technology

Manual connection has low efficiency, poor reliability, and difficult to guarantee safety, especially not conducive to the realization of process automation, and difficult to adapt to the needs of modern production; the traditional spherical or conical mechanical guidance positioning method, the positioning accuracy is not high enough, it is difficult to meet accurate positioning, especially large The precise positioning accuracy of the mechanical pipeline is less than 2mm; the video control positioning adopts advanced machine vision, high-performance computing and control technology, which has high requirements for the use environment and weak anti-interference ability, which is difficult to meet the requirements of the large industrial production environment , generally only used in light industry and microelectronics industry; position sensor control method, due to relatively high manufacturing cost and use environment requirements, poor reliability and maintainability, cannot meet the needs of precise positioning
