Description

Overhead traveling crane anti-collision computer controller

The utility model relates to a kind of crownblock protector of drilling machinery, the computer controller of a kind of overhead traveling crane anti-collision of definitely saying so.

At present, be used for oil, natural gas extraction, geoexploration and seek phreatic all kinds of big-and-middle-sized rig, during operation in the open air, though used old-fashioned anticollision devices such as weight hammer type, but owing to mainly be the position of judging trolley block by driller's eyesight, at inclement weather, poor visibility just is difficult to judge exactly the actual position of coaster on tens meters high derricks, if driller's work fatigue is absent minded, trolley block and overhead traveling crane very easily take place bump against, the great serious accident that causes derrick to be subjected to displacement directly causes economic loss hundreds of thousands of at least, big to millions of, still there is not the technical barrier that the failure-free way solves this puzzlement probing industry both at home and abroad now.

The purpose of this utility model is to address this problem technically at all, design a kind of all energy normal operation of various adverse weather conditions that are adapted to, can greatly improve labor intensity of operating staff, realize automatic audible alarm, brake fast automatically, can effectively avoid bumping in the drilling process control setup---the overhead traveling crane anti-collision computer controller that the overhead traveling crane grave accident takes place.

The purpose of this utility model is achieved by the following technical solution: The whole control system includes overhead traveling crane anti-collision computer controller (hereinafter to be referred as controller), brake control box, source of the gas etc. and partly forms.The controller mainframe box is suspended on the derrick cross bar, and load indicator is other over against the driller position, is convenient to operating personal and observes.Sensor in the controller is installed between winch and the air guide cock tap, link to each other with the controller main frame by lead, when winch rotates, Hall element in the sensor promptly converts the magnetic field impulse signal that rotates to electric pulse and is input in the micro computer of controller after shaping is amplified, the number value of being represented by the controller digital board through computing shows the number of turns that winch rotates, so just can come out trolley block with numeric display intuitively to the distance of process former anti-collision overhead traveling crane from the rig floor plane, it is self-possessed to allow the driller operate, and ensures safety in production.The brake control box is fixed near the brake cylinder, and by brake cable connection controller, when trolley block moves height up and down and does not cause that operating personal is noted in case surpass alert locations, controller just gives the brake control box driving voltage automatically, opening air valve makes pressurized air enter brake cylinder, finish the brake of winch, avoid accident to take place.

Of the present utility model being characterised in that, controller are given circuits, automatic temperature control circuit and power circuit by micro computer, sensor and sensor orientation change-over circuit, real-time digital display circuit, zero clearing reset circuit, audible alarm circuit, brake control circuit, bound normal danger and are formed.Sensor links to each other with its direction conversioning circuit, and the sensor orientation change-over circuit then links to each other with the micro computer mainboard by the positive and negative switch of sensor, uses when the coaster service direction is opposite with digital demonstration numerical value; The real-time digital display circuit links to each other with the micro computer mainboard by 9 core lines, the information that sensor moves coaster up and down at derrick, be transported in the micro computer by the sensor orientation change-over circuit, through after the calculation process, by digital display circuit its numerical value is shown by charactron in real time: the zero clearing reset circuit that links to each other with the micro computer mainboard, form by the anti-good electromagnetic switching circuit of various polluting properties of waterproof, show when producing error at number, elevator can be put by this circuit and realize the zero clearing elimination error that resets to the rig floor plane with practical operation; With micro computer mainboard bonded assembly audible alarm circuit, when coaster reaches the warning height, under microcomputerized control, carry out audible alarm and note with alert by the alarming horn in the warning circuit; With micro computer mainboard bonded assembly brake control circuit, at sensor the signal that coaster transfinites is passed to micro computer, after showing by digital board, micro computer is passed to the brake control box by the brake control circuit with brake signal simultaneously, and generation driving voltage unlatching air valve makes brake cylinder charge into pressurized air rapidly and brakes; Give circuits with micro computer bonded assembly bound normal danger, can under microcomputerized control, artificially set the bound normal danger, and with the digital display mode show be convenient to the operation, to guarantee production safety, during practical operation, coaster low speed is gone upward to former anti-collision overhead traveling crane normal danger and subtracts the 1-2 number by the shown numerical value of digital board, be predisposed to anti-collision overhead traveling crane upper limit normal danger, upper limit brake number deducts 1-5 number and is set at the upper limit alarm position, and it highly is to aim at coaster to set for the assurance personal safety when descending that lower limit normal danger and lower limit are reported to the police; By having the automatic temperature control circuit of temperature booster, temperature switch and intermediate relay, can make controller under adverse weather condition, keep normal operation; Power circuit is made of the logic constant voltage power suspply that has watchdog function, has very strong noiseproof feature, can avoid program to lose or dap in strong interference environment, to guarantee the normal operation of motherboard circuit.

Good effect of the present utility model is: when (1) rig trolley block moves up and down, can show its height up and down automatically, the driller can look at digital the demonstration straight, controls coaster exactly, and is not subjected to weather influence; (2) can bound brake and alert locations be set arbitrarily according to the rig particular case; (3) the coaster rise height is not when the driller takes action in case surpass the upper limit alarm position, and upper limit brake will automatically realize brake by the brake control box rapidly; (4) this controller has and is placed in the other long-range reset switch of driller's operator's station, can be easily coaster be carried out 0 zero (during elevator contact rotating disk is 0) position proofreaied and correct; (5) automatic temp controller in the controller can guarantee controller can be under the adverse weather condition of extremely frigid zones normal operation; (6) controller adopt hermetically sealed design, easy and simple to handle, can be explosion-proof, waterproof, anti-pernicious gas be essential by all kinds of big-and-middle-sized rig field works.
