Description
Technical field
The utility model relates to oil exploration drilling and coal gas layer drilling-production equipment parts, specifically is the two autoelectrinic anti-collision overhead traveling cranes of a kind of number.
Background technology
In oil exploration drilling and the coal gas layer drilling-production equipment, the landing of drill carriage is controlled by operating personal, if the untimely meeting of braking when the tourist bus of drill carriage rises causes crashing into the crown or percussion drill accident, the equipment that influences normally moves.Usually be provided with automatic anticollision device in traditional equipment, it generally comprises the stroke sensing device that is positioned at tourist bus rising end position and is subjected to the mechanical anti-collision electromagnetic valve of stroke sensing device control, this mechanism's anti-collision electromagnetic valve is connected between compressed air source and the gas control assembly, the gas control assembly can be controlled the brake cylinder and the power-transfer clutch air bag of overhead traveling crane, plucks power-transfer clutch and brake when being implemented in tourist bus and rising to end position.The magnetism preventing device of this structure can not be in operation operating personal is carried out active brake prompting only by control that the sensing of tourist bus position is braked, and also can't avoid the collision that overhead traveling crane is caused because of tourist bus inertia.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and can control the drill carriage operational process, can prevent crashing into the crown and prevent digital two autoelectrinic anti-collision overhead traveling cranes of percussion drill accident.
The two autoelectrinic anti-collision overhead traveling cranes of number of the present utility model include a gas control assembly, the part of the input end of gas control assembly is connected with compressed air source through mechanical anti-collision electromagnetic valve, machinery anti-collision electromagnetic valve is controlled by the tourist bus stroke sensing device, and gas control assembly mouth has the gas circuit of leading to brake cylinder and power-transfer clutch air bag; Also include a control setup main frame in the anti-collision overhead traveling crane, the detection signal input end of control setup main frame connects a Hall pulse transducer, and this Hall pulse transducer is installed in rig main shaft place and can detects the rig spindle speed; The control command mouth of control setup main frame is connected to the control part of an air operated control electromagnetic valve, and this air operated control electromagnetic valve and above-mentioned mechanical anti-collision electromagnetic valve are connected in parallel between gas control assembly and the compressed air source.
Described control setup main frame has alarm signal output ends, and alarm signal output ends is connected with annunciator.
Described control setup main frame also has the controlled variable input end, and the controlled variable input end connects a hand-held input device.
The utility model has increased the monitoring to the rig main axis rotation number of turns on the basis of common anti-collision overhead traveling crane, can accurately obtain the drill carriage stroke signal, near tourist bus upward stroke terminal point the time, send alerting signal rapidly, and make automatically in good time and pluck power-transfer clutch and brake, improved the prevention of accident effect of anti-collision overhead traveling crane.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
The specific embodiment
As shown in the figure, the two autoelectrinic anti-collision overhead traveling cranes of this number include a gas control assembly 1, the part of the input end of gas control assembly is connected with compressed air source through mechanical anti-collision electromagnetic valve 2, machinery anti-collision electromagnetic valve is controlled by the tourist bus stroke sensing device, and gas control assembly mouth has the gas circuit of leading to brake cylinder and power-transfer clutch air bag; Also include a control setup main frame 3 in the anti-collision overhead traveling crane, the detection signal input end of control setup main frame connects a Hall pulse transducer 4, and this Hall pulse transducer is installed in rig main shaft 5 places and can detects the rig spindle speed; The control command mouth of control setup main frame is connected to the control part of an air operated control electromagnetic valve 6, and this air operated control electromagnetic valve 6 and above-mentioned mechanical anti-collision electromagnetic valve 2 are connected in parallel between gas control assembly 1 and the compressed air source.The alarm signal output ends of control setup main frame is connected to annunciator 7, is used for operating personal is carried out alarm.The controlled variable input end of control setup main frame connects a hand-held input device 8, is used for importing controlled variable.
The utility model can adopt following intellectuality prompting and the some step of stopping: when rig is transferred height to the 1st group of anti-height, host-initiated speed is judged, when transferring first group of speed that speed sets greater than the scene, main frame output alarm and point are stopped, brake n automatically terminated after second, slowed down lowering velocity; When transferring height to second group of anti-height, host-initiated speed judges, when transferring second group of speed that speed sets greater than the scene, main frame output alarm and point are stopped, and brake n automatically terminated after second, slowed down lowering velocity, prevented the generation of " percussion drill " accident.
