Description
Technical field
The present invention belongs to hoisting crane technical field, particularly a kind of crane hoisting device of steel wire rope stretching device.
Background technology
For saving resource, implement green construction, the precast concrete block usually adopting certain specification is laid in construction site shoofly and place, but these prefabricated sections with rated weight transport to scene after unload and lay problem in place and be difficult to solve.Consider that workyard needs compact, the weight-lifting equipment of simple operation is laid to complete shoofly and place, the winding plant of weight-lifting equipment also answers compact conformation.When prefabricated section is unloaded, it is needed to move to lower height from certain altitude, when in weight-lifting equipment, the suspension hook of winding plant is connected on weight, steel rope is not in tensioning state, if now hoisting heavy, lineoutofservice signal pull sharply increases, reduce service life of steel wire rope, meanwhile, due to steel wire rope looseness, cause wirerope-winding on reel, easily occur job-hopping or skidding and to cause steel rope to arrange loose unordered; When weight lifts by crane, reel must realize irreversible directed movement, slowly lower height is down to again after lifting, steel rope frangible section release in falling if slow on reel, weight declines and accelerates, lineoutofservice signal pull still can sharply increase, if the steel rope frangible section on reel causes it to unclamp because of its unordered winding, then weight can suspend and aloft can not decline.
Summary of the invention
For above-mentioned defect, the technical matters that the present invention solves is, provides a kind of winding plant of steel wire rope stretching device, its compact conformation, can make steel wire tensioning before weight lifting, during lifting, reel orientation is safe and reliable to operation, and it is consistent that steel rope tightens up direction.
The present invention solves the problems of the technologies described above and realizes by the following technical solutions: the crane hoisting device of described steel wire rope stretching device, comprise spool portion, motor and deceleration system, in spool portion steel rope through assembly pulley one ends wound on reel, other end connecting shackle, reel is supported by bearing seat, and the transmission shaft of motor, deceleration system and reel connects successively.Install unilateral bearing in described reel, unilateral bearing inner ring coordinates with transmission shaft, and outer ring coordinates with reel, steel wire rope tensioning mechanism is installed in reel side, described steel wire rope tensioning mechanism is by ratchet, ratchet, support and limiting stopper composition, ratchet is bolted on winding drum end cover, alternate on ratchet periphery ratchet slot is set, ratchet is rack-mount, ratchet is bumped in ratchet slot and engages with it under stage clip effect, described support has segmental arc, groove is offered along this segmental arc, brake cable is laid in groove, brake cable one end is fixed on support, the other end connects bar handle, pulling lower handle pulls brake cable that support is rotated along direction of pull, ratchet engages with ratchet slot, reel is servo-actuated to be tightened up steel rope, install torsion spring between support and bearing seat, release handle, support resets under torsion spring effect, described limiting stopper is arranged on bearing seat, and when ratchet drives detent to this limiting stopper, limiting stopper touches ratchet makes itself and ratchet slot depart from.
Owing to installing unilateral bearing in reel of the present invention, realize unidirectional self-lock, make this plant running safe and reliable; Adopt steel wire rope tensioning mechanism, treat that suspension hook hangs on weight, just steel rope is tightened up before preparing lifting, make steel wire rope sling for certain predetermincd tension, steel rope is in tight state, during lifting, steel rope is wound around closely on reel, avoids groove skipping of steel rope while or skidding and causes wirerope-winding loose unordered.
The transmission shaft of described motor or deceleration system or reel installs brake equipment.This arranges the safe reliability improving winding plant further.
