Accompanying drawing explanation
The accompanying drawing that forms a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Figure 1 shows that the structural representation block diagram of the embodiment of the present invention;
Figure 2 shows that the structural representation block diagram of the warning device of connecting time setup unit in the embodiment of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Refer to shown in Fig. 1, the master winch prior-warning device that the embodiment of the present invention provides, comprise: pulling force sensor, comparator, warning device, recording device and fail analysis device, except pulling force sensor need to be installed near the rope (as steel rope) of master winch, other devices can concentrated setting controlling in the operator's compartment of master winch, so that remind in time the tractor driver in operator's compartment.
Pulling force sensor is for detection of the rope pull of master winch, and pulling force sensor is connected with comparator signal, and comparator is connected with warning device and recording device signal, and recording device is connected with fail analysis device signal.The maximum upper limit pulling force of setting rope in comparator is predetermined upper limit pulling force, pulling force sensor transmits the pulling force signal on steel rope in real time, the master winch rope pull detecting at pulling force sensor meets or exceeds after the predetermined upper limit pulling force of setting, comparator sends energizing signal to warning device, warning device sends alerting signal to master winch tractor driver, and recording device records alarm operation.
For the effect that makes to report to the police is more obvious, as shown in Figure 2, this alerting signal comprises picture and text alarm message, and warning device comprises: display module and sound module; Display module is used for showing this picture and text alarm message; This picture and text alarm message comprises word alarm message and figure alarm message, and display module comprises word-information display unit and pattern displaying unit, and word-information display unit is for the content of word display text alarm message; Pattern displaying unit is for the picture of display graphics alarm message; Be specially, word-information display unit shows that on control cabin telltale the main hoisting tension flicker word that transfinites reminds, and pattern displaying unit shows master winch motion graphics flicker picture on control cabin telltale.
As shown in Figure 2, sound module is for auditory tone cues alarm message; Sound module comprises buzzer phone, coordinates the demonstration of above-mentioned display module, and additional buzzer phone carries out audible alarm.
In order to control the buzzing time of buzzer phone in real work, time setting unit that can this buzzer warning time of setup control in control cabin, as shown in Figure 2, time setting unit is connected with buzzer signal, for controlling buzzer warning time length.For the ease of the tractor driver of prompting operation master winch, preferably buzzer phone is arranged in the control cabin of controlling master winch, be set together with main control equipment.
In addition, as shown in Figure 1, the recording device of embodiment of the present invention setting is the pulling force overrun condition in order to record master winch, be specially, in this master winch prior-warning device, be provided with and comparator signal linkage record device, wherein, when comparator sends to warning device energizing signal, comparator also can send energizing signal to recording device; Recorded information receives after this energizing signal, records alarm operation.
Understand in time fault content for the ease of tractor driver, and accurate failure judgement information, in this recording device, go back signal and be connected with fail analysis device, the alarm operation of fail analysis device for recording in analytic record device; Corresponding to this alarm operation, it is this alarm failure what operation causes that this fail analysis device can be prompted to tractor driver to fault analysis in time, avoids tractor driver's violation operation again, causes master winch fault.
Can in the time that main hoisting tension exceedes maxim, carry out automatic record by recording device is set, convenient service personnel carry out after-sales service on the one hand, according to the master winch failure record of rotary drilling rig, instruct tractor driver better to safeguard rig; Damage at customers' responsiveness associated mechanical part on the other hand situation time, can be by checking failure record, client is fed back to the reason that fault produces and describes.
