Abstract
The utility model provides a kind of core gamma survey instrument with protective device, comprise rock core delivery platform (5), travelling belt (4), industrial computer, frequency converter and travelling belt motor, the afterbody of rock core delivery platform (5) is fixed with afterbody guardrail (3), the position nearer at distance afterbody arranges a travel switch (2), the position far away at distance afterbody arranges an optoelectronic switch (1), whether optoelectronic switch (1) puts in place for responding to rock core, and output signal to industrial computer when putting in place, controlling frequency converter by industrial computer makes travelling belt motor shut down, whether travel switch (2) puts in place for responding to rock core, triggers the power-off of travelling belt motor when putting in place.The utility model can make equipment safer.
Description
Technical field
The utility model relates to a kind of core gamma survey instrument.
Background technology
Core gamma survey instrument is mainly used in oilfield prospecting developing field, it on-the-spot can carry out Quick Measurement to the core gamma value that drilling well is taken out in the wild, and result is printed, both improve the accuracy that gamma value is measured, also greatly shorten the work period simultaneously, increase work efficiency, reduce detection cost.Existing core gamma survey instrument forms primarily of travelling belt, gamma-ray probe, industrial computer and printer.When core moves on a moving belt continuously, completed by gamma-ray probe and the gamma value of whole core is measured.Relatively simple for structure due to existing core gamma survey instrument travelling belt, just by the start and stop of a button control travelling belt, so the measurement of whole core gamma value needs manual intervention more, operate more loaded down with trivial details, and owing to travelling belt there is no the monitoring and guard system of installing core movement position, in unattended situation, also be easy to occur because travelling belt does not stop to drive core to travel forward continuously, and core is surprisingly dropped from travelling belt, precious core can be made like this to suffer damage, cause huge economic loss.
Utility model content
In order to solve the problem, the purpose of this utility model is based on current existing core gamma survey instrument, by the transformation and upgrade to core gamma survey instrument, reaches the production of saferization.For achieving the above object, the utility model takes following technical scheme to realize:
A kind of core gamma survey instrument with protective device, comprise rock core delivery platform (5), travelling belt (4), industrial computer, frequency converter and travelling belt motor, the afterbody of rock core delivery platform (5) is fixed with afterbody guardrail (3), it is characterized in that, the position nearer at distance afterbody arranges a travel switch (2), the position far away at distance afterbody arranges an optoelectronic switch (1), whether optoelectronic switch (1) puts in place for responding to rock core, and output signal to industrial computer when putting in place, controlling frequency converter by industrial computer makes travelling belt motor shut down, whether travel switch (2) puts in place for responding to rock core, triggers the power-off of travelling belt motor when putting in place.
This utility model adds an optoelectronic switch 1, travel switch 2 and afterbody guardrail 3 on the basis of original rock core gamma survey instrument.Wherein optoelectronic switch 1 is triggered after being mainly used in treating core gamma survey, and optoelectronic switch 1 outputs signal to industrial computer, controls frequency converter travelling belt motor is shut down by industrial computer.The Main Function of travel switch 2 is, if when optoelectronic switch 1 can not control travelling belt stopping for a certain reason, core is moved forward by optoelectronic switch 1, finally collide optoelectronic switch 1 travel switch 2 below, travel switch 2 can directly control the power-off of travelling belt motor, and then makes travelling belt out of service.Afterbody guardrail 3 plays last protective effect, namely when optoelectronic switch 1 and travel switch 2 all ineffective time, prevent because travelling belt is out of service and make core drop from travelling belt.This guard system installed by existing core gamma survey instrument, core gamma survey instrument can be made to use safer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of rock core gamma survey instrument after improving.
Fig. 2 is the partial view of Fig. 1.
1. optoelectronic switches, 2. travel switch in figure, 3. afterbody guardrail, 4. travelling belt, 5 rock core delivery platforms.
Embodiment
See Fig. 1 and Fig. 2, the utility model is applicable to core gamma survey instrument, i.e. core gamma survey instrument guard system on the basis of original core gamma survey instrument, and native system is made up of an optoelectronic switch 1, travel switch 2 and afterbody guardrail 3.Wherein optoelectronic switch 1 be mainly used in until core gamma survey is complete triggered after, control travelling belt out of service.The Main Function of travel switch 2 is if when optoelectronic switch 1 can not control travelling belt stopping for a certain reason, core can move on, until collide travel switch 2, travel switch 2 can make the direct power-off of travelling belt motor, and then makes travelling belt out of service.Afterbody guardrail 3 plays last protective effect, namely when optoelectronic switch 1 and travel switch 2 all ineffective time, prevent because travelling belt is out of service and make that core is unexpected from travelling belt to drop.
Concrete implementation method is as follows: the start button first pressing lower conveyor belt, core is normally placed on travelling belt and carries out gamma survey, after to be measured, core is driven by travelling belt and moves on, when proceeding to the position of optoelectronic switch 1, core will trigger optoelectronic switch 1, and optoelectronic switch 1 outputs signal, and control frequency converter make travelling belt motor out of service by industrial computer.If optoelectronic switch 1 lost efficacy for a certain reason, core can move on, when core arrives the position of travel switch 2; core can touch travel switch 2; travel switch 2 directly can control motor power-off, travelling belt is shut down, plays the effect of duplicate protection.When 1. photoswitcs and 2. strokes open the light all lost efficacy time, in order to avoid core drops from travelling belt, travelling belt afterbody has installed again afterbody guardrail 3 additional, can drop play last protective action to the accident of core.
Claims (1)
1. the core gamma survey instrument with protective device, comprise rock core delivery platform (5), travelling belt (4), industrial computer, frequency converter and travelling belt motor, the afterbody of rock core delivery platform (5) is fixed with afterbody guardrail (3), it is characterized in that, the position nearer at distance afterbody arranges a travel switch (2), the position far away at distance afterbody arranges an optoelectronic switch (1), whether optoelectronic switch (1) puts in place for responding to rock core, and output signal to industrial computer when putting in place, controlling frequency converter by industrial computer makes travelling belt motor shut down, whether travel switch (2) puts in place for responding to rock core, triggers the power-off of travelling belt motor when putting in place.
