In addition, also can comprise weight transduser 11 according to drilling and repairing well equipment anti-collision automatic protector of the present utility model.Figure 3 shows that the schematic block diagram that has the drilling and repairing well equipment anti-collision automatic protector of weight transduser 11 according to of the present utility model.As shown in Figure 3, the purpose that weight transduser 11 is set is for protection equipment and personal safety equally.Weight transduser 11 can adopt conventional pressure transmitter.Correspondingly, in the liquid crystal display panel, show suspending weight parameter value 32b, as shown in Figure 2.The fracture load of drilling tool when CPU 30 suspending weight protection values are set to the activity unfreezing for example is 55KN (thousand Ns).Be provided with according to this, when the suspending weight of reality during near 55KN, alarm unit 34 just sends alarm signal and reminds operating personnel to note.When the suspending weight value of reality surpassed 55KN, protections such as control module 32 outputs are died, brake were instructed to and are protected executing agency 41,42 (as shown in Figure 5), thereby avoid the generation of accident.Under the unexpected weightless situation of suspending weight, can also cooperate drum rotation speed protection simultaneously, this will be described in detail below.
Fig. 4 is shown as the block diagram according to the drilling and repairing well equipment anti-collision automatic protector of another one embodiment of the present utility model.According to preferred implementation as shown in Figure 4, drilling and repairing well equipment anti-collision automatic protector of the present utility model also can comprise puff sensor 12.The same with anti-bump sensor 10, puff sensor 12 can be a kind of known near switch, for example, and the E2E-X2D1-N that Omron Corp produces, and be installed on the auxiliary stand that drags for husky cylinder.Puff sensor 12 is used in the middle of swab carries out the process of suction operation, detects the rotation of dragging for husky cylinder, and imports detected data into CPU 30.CPU 30 utilizes this tachometer value to determine the swab place suction degree of depth by the long definite method of wire rope described later.Drilling and repairing well equipment anti-collision automatic protector according to this embodiment can be operated under two kinds of patterns, i.e. anti-collision mode of operation and suction operation pattern.The concrete principle of anti-collision mode of operation and operate in above be described, therefore here no longer describe.
In this embodiment, anti-collision mode of operation and suction operation pattern can be provided with by the function key that is provided with on controller.When being in suction operation pattern following time according to drilling and repairing well equipment anti-collision automatic protector of the present utility model, to be in the anti-collision mode of operation under similar, show anti-collision distance, suction number of times, the suction degree of depth, drum rotation speed, suspending weight parameter in the liquid crystal display panel.Operating personnel can observe directly the situation of change of parameter and the variation of swab position; when swab near well head; when displacement surpasses being provided with of being scheduled to; central control unit 30 can in time send alarm signal by alarm unit 32 and remind operating personnel; respective change also takes place in the distance parameter color of the anti-collision distance that shows on the liquid crystal display simultaneously; meanwhile, control module 32 output protection control signals are avoided the generation of accident to finish safeguard measures such as brake or cut-out source of the gas.Similar to the anti-collision mode of operation, LED lamp 31f can show in a different manner according to the distance of swab and well head.
Collection suspending weight parameter in suction operation pattern following time is for protection equipment and personal safety equally.As mentioned above, when the suspending weight of reality during near the protection value that sets in advance, alarm unit 33 just sends alarm signal and reminds operating personnel to note.When the suspending weight of reality surpasses the protection value that sets in advance, protection actions such as to protection executing agency, die by execution with regard to output order for control module 32, brake, thus avoid swab to fall in the well, accident appears.
According to the utility model, the anti-collision tip distance is to obtain by the rope capacity of calculating travelling block with the suction degree of depth.Because wire rope is to twine in the mode of spiral, therefore, when calculating rope length, the length computation of its every circle just can not be simple 2 π r.The every increase one deck of rope, the also corresponding increase of its circumference, every circle rope capacity of N layer is calculated by following formula:
Wherein, D0 represents the internal diameter of cylinder, and D1 represents wirerope diameter.Its concrete method is that anti-bump sensor 10 and puff sensor 12 detect pulse signal, and pulse signal is input to CPU.Wherein, cylinder rotates a circle, and sensor will detect 4 pulses.Umber of pulse by the memory storage sensor of CPU.For adding, be reversed to and subtract when cylinder is just changeing.And calculate present place layer according to the long calculating parameter of the rope of reset, then according to above-mentioned formula, calculate the length that every layer of rope emitted.If the anti-collision pattern just with the number of share of stock FH1 of this length divided by rope, obtains the anti-collision distance.Parameter F H1 is provided with according to the concrete condition of site plant, for example adopts usually under the situation of 8 strands, 6 strands or 4 strands, and site plant adopts 8 strands, and then FH1 just equals 8.
If the suction mode, the rope length that just aforementioned calculation is gone out obtains aspirating the degree of depth divided by the number of share of stock FH2 of rope.The number of share of stock of travelling block steel wire rope was generally 1 when FH2 was suction.Reset is system according to the current length of preserving in the rope parameter of former setting and the CPU, determines to calculate the long value at zero point of rope.
According to an embodiment, judge that the mode of the rotating of cylinder is, AB phase sensor is installed on the cylinder auxiliary stand, A mutually with B mutually sensor the position as shown in Figure 6, lay respectively at the both sides of the radial line R of cylinder cross section.Like this, when the projecting point 60,61,62 that constitutes by magnet that on the cylinder end wall, is provided with and 63 by this AB mutually during sensor, A, B phase sensor detect magnetic field and export pulse, can judge to rotate and reverse.The concrete grammar example is described as follows.
Can use conventional rotary encoder or orthoscopic optics chi.The waveform of its output as shown in Figure 7.Be an AB phase incremental mode, phase phasic difference 90 degree.Can detect rotating.Utilize software program to do to judge and impose counting and add and subtract, can obtain the absolute position.When encoder is input to the CPU interface, preferably isolate,, can avoid the voltage noise to disturb problems such as potential difference because use electric current to transmit via photo coupler at a high speed.

According to the method described above, can judge the rotating of cylinder.
Fig. 5 is shown as the work control schematic diagram according to preferred embodiment of the present utility model.Describe control procedure of the present utility model below in conjunction with Fig. 2 in detail to Fig. 5.As shown in Figure 5, anti-bump sensor 10 is gathered the variation of coaster position in real time, and the data that collect are input to CPU 30.Data by 32 pairs of inputs of control module in CPU 30 compare with the value of presetting, and when result has relatively surpassed predetermined value, then report to the police by alarm unit 33.Meanwhile, control module 32 output control signals 1 and control signal 2 are moved to drive protection executing agency 40,41, thereby avoid accident to take place.
Specifically, if in the middle of the process that travelling block rises, 40 actions of control module 32 output control signals 1 driving protection executing agency are moved to order about the air operated slips that drives in the protection executing agency 40, thereby are blocked oil pipe, prevent that oil pipe from gliding.If in the middle of the process that travelling block descends, control module 32 is at first exported control signal 1, control signal 2 is exported in time-delay then.Wherein, the time of time-delay can preestablish according to the equipment situation at scene.After control module 32 output protection control signals 2, order about the electromagnetic valve action, thereby finally impel the execution valve to finish brake, that is, make coaster stop to move.Like this, just brought into play the effect of anti-pier.
According to a kind of preferred implementation of the present utility model, anti-bump sensor 10 can adopt A, the B anti-bump sensor 10 of mode of operation mutually with puff sensor 12, is arranged on the rolling stand near cylinder one end.Wherein, show drum rotation speed parameter value 31c in liquid crystal display panel as shown in Figure 2, this parameter value is used for monitoring the master rotor rotating speed and bumps to prevent travelling block and job platform.In the decline process of travelling block, if excessive velocities will the situation that control was lost efficacy occur.Anti-bump sensor 10 with real-time detected drum rotation speed transfer of data to CPU 30, CPU 30 by with real-time detected drum rotation speed data and the value that sets in advance (as, 300 enclose/minute) compare.For example set 300 and enclose/be divided into hypervelocity; if drum rotation speed surpass 300 circles/minute; the result who then compares is a hypervelocity; by control module 32 output protection control signals 2; protection control signal 2 drives the electromagnetic valve action of the second execute protection mechanism 41, thereby finally impels the execution valve to finish brake, promptly; cylinder is stopped operating, as shown in Figure 5.
If the wire rope of travelling block ruptures suddenly, weightlessness must appear in suspending weight, and the decrease speed of travelling block will increase fast simultaneously.If this occurs; weight transduser 11 can be with real-time detected transfer of data to CPU 30; the control module 32 of CPU 30 is output protection control signal 1 at first; protection control signal 1 drives 40 actions of protection executing agency; make air operated slips block oil pipe, but this moment, travelling block also had the inertia that glides.At this moment, delaying time of controller output is used to drive the protection control signal 2 of protection executing agency 41, moves to impel the electromagnetic valve in the executing agency 41, thereby stops cylinder.So just can prevent the collision of travelling block and job platform effectively.In the process that travelling block rises; if oil pipe or drill rod breaking; suddenly weightless variation also can appear in suspending weight; simultaneously owing to load changes suddenly; sudden change also can appear in the rate of climb of travelling block; this moment control module 32 output protection control signals 2, control signal 2 drives 41 operations of protection executing agencies, therefore protect effectively hypervelocity that travelling block occurs and with the overhead traveling crane collision may.
More than described anti-bump sensor 10 and weight transduser 11 detection data conditions in real time, the operation of puff sensor 12 is similar with weight transduser 11 to anti-bump sensor 10, therefore omits its detailed description of carrying out.
In addition, also can comprise memory cell 34 according to central control unit 30 of the present utility model, memory cell 34 can be preserved for example 30 day data, and preserving data break can be provided with.Be saved to memory cell 34 by above-mentioned anti-bump sensor 10, weight transduser 11 and puff sensor 12 detected parameters (for example, time, duty, the degree of depth, suction number of times, speed etc.).According to a preferred embodiment of the present utility model, storage control unit 34 can take out from central control unit 30, and is connected on the computer, the data that storage control unit 34 is preserved can be read by software.Like this, can provide the valid data of understanding entire work process for administrative staff at any time by memory cell 34.
The above is a preferred implementation of the present utility model only, and is not the qualification to the utility model protection domain.Therefore all do variations such as equivalence techniques, means to the content in manual of the present utility model and the accompanying drawing, all are contained in the protection domain of the present utility model.
