Water cooling structure of multi-arm manipulator

Abstract

The invention provides a water-cooling structure of a multi-arm manipulator. The first cooling shell is sleeved to an external support, the lower end of the first cooling shell is hinged to the first end of the second cooling shell through a first composite shaft sleeve, and the second cooling The second end of the casing is hinged to the upper end of the third cooling casing through the second composite shaft sleeve, the first end of the second cooling casing rotates axially along the first composite shaft sleeve, and the upper end of the third cooling casing rotates along the axis of the second composite shaft. With axial rotation, the medium circuit in the first cooling shell, the medium circuit in the second cooling shell and the medium circuit in the third cooling shell do not interfere with each other. The water-cooling structure of the multi-arm manipulator described in the present invention satisfies the multi-working-condition cooling of the manipulator, and the medium circuit of each cooling shell is implemented separately, which can synchronously and fully cool multiple cooling shells, increasing the cooling efficiency, and at the same time The installation structure saves installation space, reduces equipment cost and energy consumption.

Description

technical field [0001] The invention belongs to the field of mechanical arm cooling, in particular to a water cooling structure of a multi-arm manipulator. Background technique [0002] Boilers are commonly used combustion equipment. During operation, there are high temperature, strong alkali, strong acid, and ash deposition in the furnace, which is easy to cause wear and corrosion on the inner wall of the furnace, thereby affecting the heat transfer coefficient, reducing the thermal efficiency of the boiler, and causing high temperature corrosion. And increase the emission of gaseous pollutants, in more serious cases, it will lead to reduced load operation or shutdown of the unit, and even lead to dangerous accidents such as boiler tube explosion. This greatly affects the use and safety of the boiler. Therefore, companies that use boilers need to stop the boiler after a certain period of use to maintain and clean the inner wall of the boiler. Generally, the waste incinerat...

AI Technical Summary

Problems solved by technology

Boiler shutdown maintenance not only interrupts the daily business activities of the company, but also requires high maintenance costs, and some boilers are high in height, which is a high-risk manual operation

It is necessary to use a cleaning manipulator instead of manual operation under high temperature conditions, and the shell of the cleaning manipulator needs to be cooled by water. The water cooling in the prior art is formed by connecting multiple arms in series, and the cooling efficiency at the end of the arm is very poor.
