Abstract
The utility model discloses an anti-break drilling rod alarm device for a rotary drilling rig. The anti-break drilling rod alarm device comprises a weighing sensor, a data processor, an alarm, a parameter input display device, a photoelectric encoder and a displacement sensor. The weighing sensor is disposed on a power head. The photoelectric encoder is arranged on a winch. The displacement sensor is arranged on a pressurizing oil cylinder. The weighing sensor, the photoelectric encoder and the displacement sensor are all connected with the data processor which is connected with the alarm. The anti-break drilling rod alarm device for a rotary drilling rig is additionally equipped with the photoelectric encoder and the displacement sensor, and is capable of measuring folded and unfolded lengths of a wire rope of the winch as well as strokes of the pressurizing oil cylinder, thereby obtaining the mass on the wire rope and the stretching length of a drilling rod. Then, three data that have been measured are sent to the data processor for logic determination, so that alarming is conducted once signs of accidents are found. Compared with a conventional alarm device, the alarm device disclosed by the utility model provides more accurate results of logic determination.
Description
Technical field
The utility model relates to a kind of Spiral digging machine shatter-resistant drilling rod warning device, belongs to the Spiral digging machine technical field.
Background technology
Spiral digging machine has the high and environmental protection energy-saving lamp advantage of efficient as a kind of novel piling machinery, and the trend that progressively replaces other filling pile construction machineries is arranged.Drilling rod is the key component of Spiral digging machine, not single operating efficiency that directly influences Spiral digging machine, and be prone to accidents most.The common form of drilling rod accident is for falling drilling rod, and the huge impact power of generation causes unit head to damage, and the oil cylinder and the structure member thereof that bore in mast and the not care about one's appearance mechanism damage.
Number of patent application is that 20110005134.9 file discloses a kind of automatically controlled warning device that prevents drilling rod-dropping accident of rotary digging drill rig; Comprise the depth transducer that detects the drilling rod degree of depth, the LOAD CELLS of measuring drill quality; Its principle of work is to measure the drilling rod mass value of certain depth, and feedback information is to controller, and controller compares and measures value and normal value; If surpass certain limit, then trigger alarm equipment alarm.Its shortcoming is: the just simple relatively degree of depth of drilling rod and the relation between the quality, can not react the situation of drilling rod accurately, cause easily fail to report, situation such as wrong report.
The utility model content
The utility model is intended to the Spiral digging machine shatter-resistant drilling rod warning device that provides a kind of accuracy higher, can carry out logic determines, the generation of prevention apparatus accident to falling drilling rod accident sign.
The purpose of the utility model can reach through following measure: a kind of Spiral digging machine shatter-resistant drilling rod warning device; Comprise LOAD CELLS, data processor, alarm and parameter input and display device; Also comprise photoelectric encoder, displacement transducer; Said LOAD CELLS is installed on unit head, and photoelectric encoder is installed on the winch, and displacement transducer is installed on the pressurization oil cylinder; Said LOAD CELLS, photoelectric encoder and displacement transducer all are connected with data processor, and data processor is connected with alarm.
The technique scheme difference with the prior art is: this Spiral digging machine shatter-resistant drilling rod warning device has been installed photoelectric encoder on winch; On the pressurization oil cylinder displacement transducer has been installed; Can measure the stroke of winch cable convergent-divergent length and pressurization oil cylinder; Thereby obtain the quality on the wire rope, the length that drilling rod stretches out, import three kinds of data that record into data processor again and carry out logic determines, thereby the accident sign is reported to the police.Only survey the warning device of the drilling rod quality and the degree of depth before comparing, the result is more accurate for the disclosed warning device logic determines of the utility model.
Further, in order to improve the arithmetic capability of data processor, said data processor is a single-chip microcomputer; In order to improve the warning effect, said alarm is an audible-visual annunciator.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model Spiral digging machine shatter-resistant drilling rod warning device embodiment.
Embodiment
A kind of Spiral digging machine shatter-resistant drilling rod warning device; As shown in Figure 1: as to comprise LOAD CELLS 1, photoelectric encoder 2, displacement transducer 3, single-chip microcomputer, audible-visual annunciator, display screen and keyboard; LOAD CELLS 1 is installed on unit head 8; Photoelectric encoder 2 is installed on the winch 9, and displacement transducer 3 is installed on the pressurization oil cylinder 10, and said LOAD CELLS 1, photoelectric encoder 2 all are connected with single-chip microcomputer 4 with displacement transducer 3; Single-chip microcomputer 4 is connected with audible-visual annunciator, and single-chip microcomputer 4 also is connected with display screen and keyboard.
The workflow of this Spiral digging machine shatter-resistant bar warning device is following:
(1) can be easily each item structural parameters and the alarm parameters of rotary drilling rig drilling rod protective device be provided with through keyboard and display screen.
(2) simulating signal of the drilling rod that collects respectively of displacement transducer 3, LOAD CELLS 1 and photoelectric encoder 2 length of stretching out, the quality on the unit head, the quality on the wire rope is converted into digital signal with simulating signal again.
(3) single-chip microcomputer 4 is according to the duty and the structural parameters of rotary drilling rig drilling rod, calculates and demonstrates the quality of drilling rod on the duty, unit head of drilling rod and the working depth of drilling rod and judge whether to fall the possibility of drilling rod, and make corresponding processing.When the rotary drilling rig drilling rod was in abnormal operating state, audible-visual annunciator sent sound and light alarm, reminded operating personnel to note, prevented to fall the generation of drilling rod accident.
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.
Claims (3)
