Device and method for picking up strong anchor rod on coal face

Abstract

The invention discloses a device and method for picking up a strong anchor rod on a coal face. The device for picking up the strong anchor rod on the coal face comprises steel anchor rods which are sequentially inserted side by side at intervals on the vertical face of a coal seam in the tunneling direction of a coal machine, wherein the steel anchor rods which are inserted side by side at intervals fall off row by row along with the excavated coal seam along with tunneling of cutting teeth of the coal machine, a steel anchor rod picker is arranged between the row of steel anchor rods to be touched by cutting teeth of the coal machine and the multiple rows of steel anchor rods arranged at intervals behind, the steel anchor rod picker comprises two supporting rods, the two supporting rods are arranged in parallel in a front-back mode, a plurality of air cylinders are fixed to the two supporting rods side by side at intervals, an air pump supplies air to the air cylinders, and the number of the air cylinders is the same as that of the steel anchor rods which are arranged in each row in an up-down spaced mode; a front pull rope is connected to a telescopic arm of each air cylinder, a rear pull rope is connected to the rear supporting rod, the front pull ropes are used for being connected with the row of steel anchor rods needing to be touched by the cutting teeth of the coal machine in a bolting mode, and the rear pull rope is used for being connected with the steel anchor rods behind the air cylinders in a bolting mode.

Description

Technical field [0001] The present invention is directed to a coal-coating surface power anchor pickup device and method. Background technique [0002] The comprehensive columns need to be entered into the anchor before the coal mining to maintain the stability of the coal seam, and during the advancement of the coal, the anchor will be bent out of the coal. Therefore, in order to avoid being bent out by the coal machine, the anchor needs to be taken during the production advancement of the coal machine, and the current operation must stop the coal and the front scraper transport machine to pick up, affect the production time, and affect the work. Personal safety. If the anchor does not take timely and reliable, it will be shipped in the coal stream system, which is harmful to the belt of the entire coal stream system, and the mine has occurred every year due to the anchor causes a belt tear accident. Inventive content [0003] It is an object of the present invention to propose...

AI Technical Summary

Problems solved by technology

Therefore, in order to avoid being bent and dragged out by the coal machine, the bolt needs to be picked up during the production and advancement of the coal machine. The current operation is to stop the coal machine and the front scraper conveyor to pick it up, which affects the production time and also affects the work. personal safety of personnel

And if the bolts are not picked up in a timely and reliable manner, they will be transported out along the coal flow system, which will cause damage to the belt of the entire coal flow system. The belt tearing accidents caused by the bolts in the mine every year happen from time to time.
