Description
Technical field
The present invention relates to the monitoring that a kind of underground coal mine creeps into and creep into scale devices.
Background technology
Existing monitoring drilling well scale devices have the Chinese Patent Application No. for underground coal mine be 200810303703.6 " coal mine gas bleeder off hole depth measurement method and measuring apparatus ".This patented technology only can be used for the rig of hydraulic, and is crept into chi calculated by hydraulic pressure oil mass air exercise, and hydraulic pressure oil mass is difficult to accurately obtain.
Summary of the invention
The rig of hydraulic is only can be used in order to overcome existing " coal mine gas bleeder off hole depth measurement method and measuring apparatus ", and creep into chi calculate by hydraulic pressure oil mass air exercise, hydraulic pressure oil mass is difficult to the defect accurately obtained, the invention provides a kind of underground coal mine based on RFID technique and creep into monitoring system, this underground coal mine creeps into monitoring system and can be used for various rig, do not need to creep into chi by hydraulic pressure oil mass air exercise to calculate, measure accurately, can to creeping into data real time record.
Technical scheme of the present invention is: this underground coal mine creeps into monitoring system and comprises drilling rod, U-shaped groove is provided with in the middle part of drilling rod, electronic tag includes the numbering of drilling rod, material, bar length and clocked command, electronic tag is embedded in U-shaped groove, U-shaped groove notch place embeds the protective cover that one deck is made primarily of silicon nitride material, explosion-proof reader is built-in with signal projector, signal receiver, timer, signal processor and data storage card, be added with vibrationproof rubber cushion below explosion-proof reader and be bolted on rig draw-in groove, dustproof glass cover is added with above explosion-proof reader.
Advantage of the present invention: can be used for various rig, does not need to creep into chi by hydraulic pressure oil mass air exercise and calculates, measure accurately, can to creeping into data real time record.The engineering quantity that can automatically-monitoredly creep into, time.Be applicable to automatically-monitored coal mine underground construction boring time creep into the parameter such as yardstick, drilling time, whether true and reliable with check borehole construction works amount, whether drilling quality reaches designing requirement.

Detailed description of the invention
In Fig. 1,2,3,4; U-shaped groove 2-1 is provided with in the middle part of drilling rod 2; electronic tag 1 includes the long and clocked command of the numbering of drilling rod 2, material, bar; electronic tag 1 is embedded in U-shaped groove 2-1; U-shaped groove 2-1 notch place embeds the protective cover 2-2 that one deck is made primarily of silicon nitride material, is not worn to protect electronic tag 1.Explosion-proof reader 3 is built-in with signal projector, signal receiver, timer, signal processor and data storage card 3-2, explosion-proof reader 3 is added with vibrationproof rubber cushion 3-3 and is bolted on rig draw-in groove 4 below, and explosion-proof reader 3 is added with dustproof glass cover 3-1 with dust-proof or waterproof above.
Signal projector, for sending the electromagnetic wave of fixed frequency, gathers the information on electronic tag 1 by signal receiver, and signal processor is used for the information of recorded electronic label and the signal of process collection and time interval T
n, data storage card 3-2 is used for the information that arrives of storage of collected and T
n.
Its course of work: in coal mine down-hole drilling work progress, rig is by drilling rod 2 section by section rotary drilling coal, rock mass, the explosion-proof reader 3 being fixedly mounted on rig draw-in groove 4 near zone scans the drilling rod 2 with electronic tag 1 entering sweep limits, read the electronic tag 1 on drilling rod 2, information stored in electronic tag 1 is carried out processing and record.After construction hole to be drilled, the storage card of explosion-proof reader 3 is connected into computer, shows and arrange drilling information.
The present invention can record drilling rod quantity, creep into yardstick and drilling time, achieves the automation of coal mine down-hole drilling construction monitoring.
