Description
Technical field
The utility model belongs to a kind of depth detection apparatus field, relates in particular to the depth detection apparatus of rotary drilling rig drill bit.
Background technology
When rotary drilling rig creeps into, need in time to grasp the depth value of drill bit in the stratum.At present; Measuring the way of bit depth both at home and abroad, is on the wire rope directive wheel on rotary drilling rig mast top, installs near switch and detects the directive wheel rotating cycle; Indirect calculation goes out the length that wire rope slips over directive wheel and obtains the bit depth value, and above-mentioned this method has two shortcomings:
1. the precision that detects is low, and when quick decline of drill bit and unsteady transferring, relative slippage can appear in wire rope and directive wheel, when practice of construction is measured, finds, the error of 60m is above lOm.So in equipment construction, often measure once more because of error greatly needs to adopt other manual method, will need a lot of times proofread and correct the depth value of drill bit decline like this, and the result who obtains inaccuracy often.
2. because complicated at the working environment of rotary drilling rig; Usually can meet accident; For example: when rotary drilling rig falls the brill phenomenon, still still continue to detect the length that wire rope slips over directive wheel near switch, this is that the data that obtain not only there is no need; Even the rotary drilling rig driver's cabin in the staff may be hoodwinked by this illusion, can not in time make correct processing.
The utility model content
The utility model provides a kind of accuracy of detection for the degree of depth high, can in time reflect and fall the rotary drilling rig depth detection apparatus that bores phenomenon.
In order to solve the problems of the technologies described above; The utility model provides following technical scheme: the rotary drilling rig depth detection apparatus; Comprise the displacement transducer that is installed on the rotary drilling rig master winch, be installed on the inductor of weighing on the drilling rod steel wire, also have a pulse coder that is installed in the rotating shaft of rotary drilling rig wire rope drum; The signal line of displacement transducer, weigh inductor and pulse coder is connected CPU, and cpu interface connects display screen and alarm.
Adopt technique scheme; In the utility model; Utilize the displacement transducer on the rotary drilling rig master winch to detect the degree of depth jointly with the pulse coder that is installed in the rotating shaft of rotary drilling rig wire rope drum, the data upload that displacement transducer and pulse coder are obtained is to CPU, through contrast, analysis; Data upload after will handling again is to display screen, can obtain accuracy of detection height, depth data that accuracy is strong like this.Be installed on the inductor of weighing on the drilling rod steel wire simultaneously and can monitor the gravity situation of drill bit at any time; The gravimetric data of drill bit is uploaded to CPU; Through the CPU analysis, if be lower than the minimum predetermined value of bit gravity, CPU connects alarm buzzer; Alarm buzzer is reported to the police, and the data upload after CPU will be analyzed simultaneously is to display screen.
Further, described displacement transducer is the high accuracy eddy current displacement sensor, and the high accuracy eddy current displacement sensor possesses remarkable resolution ratio and speed ability; Satisfy various actual demands; The high accuracy eddy current displacement sensor is installed on the master winch reductor, is convenient to install, and is not fragile.
Further; Described central processing unit for processing, analyze displacement transducer, data that the inductor of weighing, pulse coder are uploaded; With the data upload after analyzing to display screen; The depth detection data that obtain like this are accurate more, reasonable, and on display screen, the driver can the very intuitive and accurate variation of seeing the degree of depth with the data upload after analyzing.
Further, described CPU, display screen, alarm are installed in the driver's cabin of rotary drilling rig, make things convenient for watching of driver, in case run into emergency, the driver can make a response at once.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of rotary drilling rig depth detection apparatus.
The specific embodiment
As shown in Figure 1: the rotary drilling rig depth detection apparatus; Comprise the displacement transducer that is installed on the rotary drilling rig master winch; Described displacement transducer is the high accuracy eddy current displacement sensor, and the high accuracy eddy current displacement sensor is installed on the reductor of master winch, and the model of high accuracy eddy current displacement sensor is KD2306; Be installed on the inductor of weighing on the drilling rod steel wire; Also have a pulse coder that is installed in the rotating shaft of rotary drilling rig wire rope drum, the model of pulse coder is SP1721AW158H-0, and the signal line of high accuracy eddy current displacement sensor, weigh inductor and pulse coder is connected CPU; Cpu interface connects display screen and alarm; The data that described central processing unit for processing, analysis high accuracy eddy current displacement sensor, the inductor of weighing, pulse coder are uploaded, to display screen, described CPU, display screen, alarm are installed in the driver's cabin of rotary drilling rig with the data upload after analyzing.
In the testing process, open the high accuracy eddy current displacement sensor on the rotary drilling rig master winch, open the pulse coder in the rotating shaft of rotary drilling rig wire rope drum; Open the inductor of weighing on the drilling rod steel wire, along with drilling rod descends, high accuracy eddy current displacement sensor, pulse coder, the inductor of weighing with data upload to CPU; Processing, analysis through CPU; To display screen, if fall the emergency of brill, CPU connects alarm with the data upload after analyzing; Alarm equipment alarm is even the driver can make a response.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
