Description
Technical field
The utility model relates to rotary drilling rig, is specifically related to a kind of anti-drop device with hoisting rope pressurization and lifting unit head.
Background technology
The present rotary digging drill power head fall device of not setting up defences in the industry, therefore during the rotary drilling rig bore operation, because unit head tenesmus situation can appear in the inefficacy of oil cylinder (oil cylinder effect pressurization and lifting unit head form) or wire rope (hoisting rope pressurization and lifting unit head form).In the face of this phenomenon, solution commonly used is the mode of occupation that the constructing operation personnel make regular check on cylinder seal and observe wire rope at present, judges by rule of thumb the possibility of unit head tenesmus.Concerning with the unit head of hoisting rope pressurization and lifting, have following five principal characters:
1, the stroke of pressurization and lifting unit head is longer, be generally more than 10 meters, and the cornerite of wire rope and pulley larger (generally above 90 °), because wire rope and the abrasion of pulley and the destruction of shock loading, disconnected rope present situation often appears between two pulleys;
2, on the pressurization winding reel respectively from the reel two ends, two wire rope of winding of single layer, opposite direction, one of the wire rope of both forward and reverse directions act as the lifting unit head when pressurization elevator rotated, one act as the pressurization unit head, because drum diameter is identical and the guide effect of drum rope groove, the work of pressurization elevator is orderly, the rope closing of wire rope with put the rope action norm, rope disorder cable present situation can not appear squeezing, the fracture of wire rope can not appear at reel simultaneously;
3, guide effect links to each other with the top sheave of unit head the wire rope of lifting state through pulley from the rope stretching of reel lower end, and terminal is fixed in middle mast top with steel cable clamp, and the fracture of this wire rope is the immediate cause that the unit head tenesmus occurs;
4, the wire rope of pressurized state is from the upper end rope stretching of reel, guide effect links to each other with the lower sheave of unit head through pulley, its terminal is connected with drawing cylinder after the pulley guiding, the stay cord oil cylinder is used for straining reel steel wire ropes, the fracture of pressurization wire rope, unit head can't be pressurizeed, can not cause the unit head tenesmus;
5, middle mast top and lower mast foot are installed respectively block; be used for (the setting of lower mast bottom block of mechanical position limitation unit head stroke; can play certain protective effect to the tenesmus of unit head), middle mast is equipped with the upper limit position switch (before the upper limit block) of unit head as the dual fail-safe of upper limit in addition.
Analyze through above feature and on-the-spot disconnected rope fault to the hoisting system pressurization, we sum up the tenesmus of unit head, mainly are because the fracture of boom hoist cable between two pulleys.During hoist ropes break, if the lower limit block (impulse force can be very not large between unit head and the lower limit block) of the relatively more close lower mast of unit head, unit head then can be blocked by the lower limit block and be unlikely to fall in the hole of having bored; Yet generally, unit head lower limit block and oil connection often appear thrusting during the unit head tenesmus, in tens meters deep holes that whole unit head assembly directly fallen into bored, have a strong impact on construction progress, also it is worth mentioning that, unit head is salvaged difficulty after falling into deep hole, by taking a large amount of manpower and materials, brings the tremendous economic loss.
The utility model content
Technical problem to be solved in the utility model provides a kind of defective of the wire rope that can detect and detect a flaw, the disconnected possibility of restricting of detection place in the energy maximum magnitude, thus can prevent the rotary digging drill power head anti-drop device that rotary digging drill power head falls.
In order to solve the problems of the technologies described above, the rotary digging drill power head anti-drop device that the utility model provides, frame is provided with pressurization elevator assembly, rope hoisting system, steel wire rope compression system, unit head upper limit block, middle mast, lower mast, unit head assembly and unit head lower limit block, is provided with wire rope detection and warning system at described unit head upper limit block and described middle mast upper sheave section wire rope place.
The master controller communication connection of described wire rope detection and warning system and the electric assembly of rotary drilling rig.
Described wire rope detects and the structure of warning system is that sensor cluster is electrically connected with the intelligent data acquisition processor, described intelligent data acquisition processor is electrically connected with main website, described main website is electrically connected with the controlling alarm case, and described controlling alarm case is electrically connected with alarm lamp.
Described wire rope detects and described sensor cluster and the described intelligent data acquisition processor of warning system are installed in described unit head upper limit block and described middle mast upper sheave section wire rope place, described main website and described controlling alarm case are installed in the driver's cabin, and described alarm lamp is installed on the covering of getting on the bus.
Adopt the rotary digging drill power head anti-drop device of technique scheme, the wire rope detection is used for detecting and the flaw detection defect in rope with warning system, the possibility of the disconnected rope of detection place in this installation site energy maximum magnitude; At the newly-increased control program of the master controller of the electric assembly of rotary drilling rig, be used for force users to change and detected problematic wire rope by sensor.Solved with hoisting rope pressurization and when promoting unit head, unit head is because of hoist ropes break this destructive malfunction that drops; When fault alarm sends alarm sound, prompting operation and constructor should be in time change steel rope more; Advantage of the present utility model and good effect are:
1, the wire rope of the utility model unit head anti-drop device by between middle mast upper sheave and unit head upper limit block increases by a cover wire rope and detects sensory package, final realize warning and with the interlock function of main operating mode;
2, newly-increased modular system is wireless telecommunications, installs simple and conveniently, and alarm signal can be accessed master controller, can show screen display steel rope replacing information, and the caution of dual-alarm signal allows operate and more feels at ease;
Facts have proved by the master controller relative program, can accomplish to interlock with main operating mode, force the user to the steel rope replacing of high-risk status, realize the ultimate anti-falling protection of unit head.
In sum, the utility model is a kind of defective of the wire rope that can detect and detect a flaw, the disconnected possibility of restricting of detection place in the energy maximum magnitude, thus can prevent the rotary digging drill power head anti-drop device that rotary digging drill power head falls.
