Abstract
The utility model discloses a crown block intelligent anti-collision device of a well borer and a workover rig in petroleum industry. The crown block intelligent anti-collision device comprises three portions of a signal sensing system, a microcomputer and an executive display system, which are connected in turn through lap joint mode, wherein the signal sensing system comprises a magnet steel and a magnetoelectric transducer which are installed on a hoisting drum holder, the executive display system comprises four portions as a relay, a digital height displayer, a luminosity-changing light beam displayer and an alarm. When moving on the magnet steel which is arranged on a hoisting drum, the magnetoelectric transducer produces bidirectional positive pulse signals, transfers the signals to the microcomputer for counting and calculating the rotation of the hoisting drum and then transfers orders to the executive display system, and the height of a crown block can be displayed on the digital height displayer and the luminosity-changing light beam displayer. When the crown block achieves a preset height, the alarm warns operators to take notice, and the power of the hoisting drum is automatically cut off and braked to guarantee the safety of personnel and equipment. The crown block intelligent anti-collision device has the advantages of intelligent control, convenient installation and reliable use.
Description
Technical field the utility model discloses the overhead traveling crane intelligence anticollision device of trepan, workover rig in a kind of petroleum industry.
In the present petroleum industry of background technology when trepan, workover rig operation, the hook suspention oil pipe drilling rod of overhead traveling crane of moving about moves up and down, move about overhead traveling crane lifting and transfer highly entirely by the visual control of operator, in case the operator is absent-minded or operate miss will cause the fixedly overhead traveling crane or bump the generation of pounding serious accidents such as well head of overhead traveling crane collision that moves about, gently then damage plant equipment, heavy then cause personal injury.Existing crownblock protector is at catch pin type travel switch of the upper end of workover rig (trepan) derrick installation, utilizes the bump of the overhead traveling crane that moves about to make the travel switch action, thereby realizes the power and the skidding of warning and cut-out hoisting drum.But because travel switch is installed in crown, constantly clashed into again, add and expose to the sun and rain, very easily damage, and maintenance difficult.Pin is also disconnected easily to be taken off, and causes personal injury.
The summary of the invention the purpose of this utility model is to provide a kind of hoisting depth of the overhead traveling crane that can timing monitoring moves about, and the power source that can in time report to the police and cut off hoisting drum automatically starts the brake system skidding simultaneously, thereby effectively prevents to move about fixedly overhead traveling crane or bump the intelligent anticollision device of overhead traveling crane of the generation of pounding serious accidents such as well head of overhead traveling crane collision.
For achieving the above object, overhead traveling crane of the present utility model intelligence anticollision device is overlapped in proper order by signal sensing system, microcomputer and execution display system three parts and to constitute.Signal sensing system is made up of the magnetoelectric transducer that is installed in the magnet steel on hoisting drum one side end face and be installed on the homonymy hoisting drum seat.Carry out display system and comprise relay, digital elevation indicator, change light bar graphic display and alarm four parts.Described magnet steel can be that four in every cover is distributed on the end face of hoisting drum.
Adopted after the said structure, the magnet steel of magnetoelectric transducer on hoisting drum produces two-way positive pulse signal when moving, and is transferred to microcomputer, and the rotation of hoisting drum is counted and calculated, and instruction is transferred to the execution display system again.Immediately on digital elevation indicator and change light bar graphic display, show the overhead traveling crane height that moves about.Alarm equipment alarm during to predetermined altitude reminds the operator to note.And automatically hoisting drum is cut off power and skidding, thereby effectively prevent to move about fixedly overhead traveling crane or bump the generation of pounding serious accidents such as well head of overhead traveling crane collision.
Description of drawings is described in further detail the utility model overhead traveling crane intelligence anticollision device below in conjunction with the drawings and specific embodiments.
Accompanying drawing is the work schematic diagram of the utility model overhead traveling crane intelligence anticollision device.
The specific embodiment as shown in drawings, magnet steel 5 is installed on the end face of hoisting drum 4 one sides, magnetoelectric transducer 6 is installed on the hoisting drum seat 1 of the same side, when magnet steel 5 passes through magnetoelectric transducer 6 fronts along with the rotation of hoisting drum 4, Hall unit in the magnetoelectric transducer 6 produces two-way orthogonal pulses signal, and is transferred to microcomputer 9 by signal cable 8.The rotation of 9 pairs of hoisting drums 4 of microcomputer is counted and is calculated, and output order is transferred to the execution display system again.The operator can import and revise each initial parameter by the parameter setting operation key of microcomputer 9.The move about height number of overhead traveling crane 2 of digital elevation indicator 11 instant playbacks, the precision height.Become light bar graphic display 12 and then can remind the operator when being about to arrive predetermined altitude, to reduce throttle in advance more intuitively, and perform the preparation of cutting off clutch and skidding.Overhead traveling crane 2 has arrived predetermined altitude if move about, and the operator is not when also taking corresponding measure, and alarm 13 can be reported to the police, and reminds the operator to note.Relay 10 begins action simultaneously, sends signal for the solenoid operated directional valve 7 of clutch on the hoisting drum 4, makes solenoid operated directional valve 7 actions, cuts off the power source of hoisting drum 4, and starts the brake system skidding.Thereby effectively prevent to move about fixedly overhead traveling crane 1 or bump the generation of pounding serious accidents such as well head, the safety of assurance operating personnel and plant equipment of overhead traveling crane 2 collision.Owing to have the multichannel security system to ensure simultaneously, the reliability height.Have Based Intelligent Control, easy for installation, service-strong advantage.
