Description
Technical field
The present invention relates to a kind of installation method of traction sheave grooving, particularly a kind of traction method of passenger elevator.
Background technology
In existing elevator installing method, traction steel-cable is normally directly installed on traction sheave, and such hoist ropes easily produces and breaks away in grooving, causes traction sheave grooving Fast Wearing.Also there is the installation method of improvement, namely on the contact surface of hoist ropes and grooving, lubricant is added, or on grooving, add wear-resistant ceramic glue serve as a contrast as anti-friction protecting, temporary transient abrasionproof effect can be played like this, but wear-resistant ceramic glue is yielding and deformation is uneven, make the tensile force ratio of traction rope sheave both sides hoist ropes be not easy to control, both sides tensile force ratio is not suitable for, and also easily produces and breaks away and cause easily causing traction sheave grooving Fast Wearing.In 6 traction steel-cables in grooving after wearing and tearing, there is the tensile force change of 1 or 2 greatly, when cage operation is to top layer, this steel rope is stressed hardly, car weight is born by all the other several steel ropes entirely, but when car down runs, this steel wire tensioning power is increasing, when moving to intermediate landing, 6 steel wire tensioning power reach basically identical, but when car is close to bottom, this steel wire tensioning power is obviously well beyond all the other several, it bears the load of most car, the shackle spring of this steel rope is caused to be subject to violent compression and to collide with rope hitch plate and send " click click " sound, and make car produce larger shake.Such installation method causes elevator to be in operation sending abnormal noise and car shake, reduces the comfort taken, meanwhile, decreases the service life of traction steel-cable, add use cost.
Summary of the invention
The object of the invention is to, a kind of traction method of passenger elevator is provided.The method can control the tensile force ratio of traction rope sheave both sides hoist ropes effectively, avoid the sideslip of hoist ropes in grooving, reduce the wearing and tearing of grooving, improve the service life of hoist ropes simultaneously, reduce use cost, and elevator can be avoided to be in operation send abnormal noise and car shake, improve the comfort taken.
Technical scheme of the present invention: a kind of traction method of passenger elevator, is arranged on hoisting elevator on traction rope sheave, comprises the steps: by hoist ropes
A. select indices to control the traction sheave within the scope of national regulations, and ensure the resistance to abrasion of each traction sheave, hardness is consistent;
B. install on each traction sheave with the cylindrical toroidal liner with hoist ropes respective transversal line, cylindrical toroidal liner is embedded corresponding sheave, this cylindrical toroidal liner radial thickness is 2-3cm, and the degree of depth between horizontal line is the 20%-32% of cylindrical toroidal liner thickness;
C. be installed on corresponding traction sheave by each hoist ropes, and adjust the tensile force of each hoist ropes, the difference making it mutual controls within 5%;
In the traction method of aforesaid passenger elevator, in step b, the material of this cylindrical toroidal liner is polyurethane synthetic, and this polyurethane synthetic, by mass parts, comprises the polyurethane of 70-80 part, the carborundum of 10-15 part and the quarz sand of 5-20 part.Adopt the polyurethane synthetic of such component wear-resisting especially, the service life of cylindrical toroidal liner can be improved like this, also considerably increase the service life of traction steel-cable.
In the traction method of aforesaid passenger elevator, in step c, judged the tensile force of each hoist ropes by the compression degree of the fag end tightening device of each hoist ropes.
In the traction method of aforesaid passenger elevator, in described step c, in each hoist ropes, install tensile force alarm device, this stress warning device first sets a specified pulling force, when the pulling force of hoist ropes exceedes specified pulling force, this tensile force alarm device can warning reminding.Arranging tensile force alarm device can early warning hoist ropes discontinuity, and can determine a certain stressed abnormal hoist ropes easily, adopts remedial measures in advance, adjusts the pulling force of each hoist ropes, prevent hoist ropes from wearing and tearing further, extend its service life.
In the traction method of aforesaid passenger elevator, described tensile force alarm device comprises pulling force sensor, chip and buzzer phone, pulling force sensor is arranged on towline head, pulling force sensor mouth connects chip, chip output connects buzzer phone, this chip sets specified value of thrust, and can set out when the pulling force of hoist ropes exceedes specified value of thrust buzzer warning.
Compared with prior art, the present invention controls the traction sheave within the scope of national regulations by selecting indices, and make its resistance to abrasion, hardness is consistent, traction rope sheave is installed the cylindrical toroidal liner with horizontal line, when each hoist ropes is installed on traction rope sheave, the mutual difference of its tensile force is made to control to constitute a kind of traction method of passenger elevator within 5%.Indices is selected to control the traction sheave within the scope of national regulations, and make its resistance to abrasion, hardness is consistent, the abrasion loss of each grooving can be made like this to be consistent, to guarantee that the difference that in subsequent step, hoist ropes tensile force is mutual can control within 5% for a long time, traction rope sheave is installed with the cylindrical toroidal liner with hoist ropes respective transversal line, cylindrical toroidal liner is embedded corresponding sheave, this cylindrical toroidal liner radial thickness is 2-3cm, the degree of depth between horizontal line is the 20%-32% of cylindrical toroidal liner thickness, the cylindrical toroidal liner of such radial wall thickness is adopted to be the optimum dimension that contriver obtains through overtesting, the stress amplitude ratio that such liner is subject to is more even, not yielding, more easily control the tensile force ratio of traction rope sheave both sides hoist ropes, adopt the horizontal line of such degree of depth, and width between this horizontal streakline bar is corresponding to the rope strand of hoist ropes, the friction coefficient between the line face of horizontal line and hoist ropes and the friction coefficient between traction sheave wheel face and hoist ropes can be made to be consistent, hoist ropes is not made to break away.In step b, the material of this cylindrical toroidal liner is polyurethane synthetic, and this polyurethane synthetic, by mass parts, comprises the polyurethane of 70-80 part, the carborundum of 10-15 part and the quarz sand of 5-20 part.Adopt the polyurethane synthetic resistance to abrasion of such component and hardness to increase substantially, the resistance to abrasion of cylindrical toroidal liner can be improved like this, be not easy hoist ropes is breakked away, also considerably increase the service life of traction steel-cable.
