Large coal bunker blockage cleaning robot

Abstract

The invention provides a large coal bunker blockage cleaning robot, relates to the technical field of warehousing equipment, and solves the technical problem of mechanical cleaning in a coal bunker. The coal bunker cleaning robot comprises a revolving mechanism, a lifting mechanism, a water storage tank, a left working arm, a right working arm, a walking car, a bunker cleaning manipulator, a balance device and a stand column; the revolving mechanism is connected with the upper end of the stand column through a gear; the lifting mechanism is arranged on the stand column; a connecting support rod is arranged at the lower end of the stand column; the left working arm and the right working arm are arranged on the connecting support rod; the balance device is arranged on the left working arm; the walking car is arranged on the right working arm; a windlass is arranged on the walking car; the bunker cleaning manipulator is connected with the walking car through a steel wire rope; and the steel wire rope is used for adjusting rotation of the left working arm and the right working arm and the position of the bunker cleaning manipulator to finish internal cleaning of a coal bunker. In addition, the coal bunker cleaning robot has the advantages of safe and efficient cleaning, wide application range and convenience for installation and disassembly.

Description

technical field [0001] The invention relates to the technical field of storage equipment, in particular to a robot device used for large coal bunkers and capable of automatically cleaning the coal bunkers. Background technique [0002] The ground coal bunker is used as an intermediate storage device for storing coal. The raw coal in the coal bunker continuously flows in and out. The upper part of the raw coal bunker structure is a cylinder, and the lower part is a hyperbolic cone. The upper opening is large, the lower opening is small, and the raw coal falls from top to bottom by its own weight. As the falling raw coal flows in the conical coal bunker, the area gradually decreases when it flows downwards, forming a greater squeeze on the raw coal itself, increasing the external force and probability of the fine coal powder sticking to the inner wall of the coal bunker, and the flow direction of the raw coal is The raw coal flows from the inner wall of the coal bunker to the...

AI Technical Summary

Problems solved by technology

Therefore, in the natural state, raw coal fine powder is very easy to stick to the inner wall of the coal bunker. After the raw coal powder sticks to the inner wall of the coal bunker, the friction coefficient increases rapidly. The use space of the coal bunker is reduced, and the production efficiency of the coal bunker is reduced, so the coal bunker needs to be cleaned regularly

[0003] The traditional cleaning of coal bunkers mainly depends on manual cleaning and blasting. The former is prone to safety accidents during the cleaning process, and the latter is difficult to control the amount of explosives, which can easily cause damage to the bunker wall.

The Chinese patent announcement number is CN201510582875.1, a circular-driven high-pressure water jet coal bunker coal accumulation cleaning device and cleaning method. Although this solution can clean the coal bunker, it has low efficiency and a small range of application bin types, especially not suitable for Cleaning of large coal bunkers on the ground

In addition, it is difficult to install coal bunker cleaning equipment in large coal bunkers, and it is inconvenient to disassemble and overhaul, so it is necessary to further improve the existing coal bunker cleaning equipment
