Method for safely using electric control gear of rotary drilling machine

Abstract

The invention discloses an electric control device safely using a rotary drilling rig which has the main technical point that the invention is provided with a first timer which is used for causting a CPU automatically read maintenance information in a first memory and display the maintenance information on a display screen of a display device when an indication set time is reached, a operation lock which is used for controlling operation state of the rotary drilling rig, a second timer which is used for causing the operation lock close the drilling rig when a control set time is reached and a comparator which is used for comparing password signals input by a input device with password signals stored in a password memory, and causing the operation lock open the drilling rig according to a correct comparison result. The invention can manage and control the drilling rig on basis of time, can greatly lower money return risk of a factory, can indicate different maintennance information in different indication period, lowers damages to equipment because maintenance is delayed, and prolongs service life of the equipment.

Description

technical field [0001] The invention relates to the technical field of rotary drilling rigs, in particular to an electric control device for safe use of rotary drilling rigs. Background technique [0002] Rotary drilling rig is a large-diameter deep hole drilling equipment. Because it uses "rotary bucket" or "rotary bucket" to borrow soil, it is called "rotary drilling rig" or "rotary bucket drilling rig". At present, rotary drilling rigs The representative model is full hydraulic rotary drilling rig. Compared with the engineering drilling rigs with mud forward and reverse circulation drilling, the construction efficiency of a full hydraulic rotary drilling rig is about a dozen of the latter, and the alkaline mud that pollutes the environment is much less during construction. , the price between them is also about dozens of times different, so the current full hydraulic rotary drilling rig is still a rather expensive equipment. The main reason for the high price of the ful...

Problems solved by technology

Compared with the engineering drilling rigs with positive and negative circulation of mud, the construction efficiency of the full hydraulic rotary drilling rig is about a dozen of the latter, and the alkaline mud that pollutes the environment is much less during construction, but , the prices between them are also about tens of times different, so the current fully hydraulic rotary drilling rig is still a very expensive equipment

The main reason why the full hydraulic rotary drilling rig is expensive is its special integral structure. It uses a high-power internal combustion engine to drive the crawler and power head drilling through a high-pressure hydraulic system. This special integral structure is difficult to produce in a single piece. High cost, must be regularly maintained and maintained during use

However, the maintenance work of the equipment during use is mainly done by the user. If the equipment is not properly maintained and maintained at the time when maintenance and maintenance are required, it will have a great impact on the service life of the rotary drilling rig. influences

Although the maintenance and maintenance information of the equipment is recorded in the manual, it cannot give prompts in a timely manner according to the current status of the equipment, which is not timely and intuitive

On the other hand, due to the high price of rotary drilling rigs, users are generally unable to purchase in full, and the manufacturer has the risk of repayment. If the payment cannot be recovered in time, the manufacturer's technical improvement work will lack the necessary financial support
