Description
Technical field
The present invention relates to elevator technology field, is specifically a kind of steel wire tension balancer for lift car.
Background technology
In the time of lift-mounting car, steel wire need to be installed, being bolted on adapter plate of fixing steel wire, bolt by connector after again through being tightened with nut again after the through hole on adapter plate.Lift car generally connects by many steel wires, and the most frequently used is the six roots of sensation, after installation, must make the tension force of all steel wires identical.In the time that steel wire is installed, be subject to the restriction of installing space at present, can only install by hand, the easy like this dynamics that causes is inhomogeneous, and the tension force of every steel wire is inconsistent, makes car discontinuity, in running process of elevator, can produce fluctuation, the stability of impact operation, makes elevator have potential safety hazard.
The only one China patent of the applicant's earlier application: a kind of steel wire tension balancer for lift car with following structure, comprise the many groups of steel wire tension equalizers that all can produce respectively identical pulling force, every group of steel wire tension equalizer comprises the connector screwing with the screw rod of steel wire of fixing lift car, linear telescopic mechanism and the adapter sleeve that is provided with expansion link; The end of described expansion link is connected with one end of connector, and described expansion link is positioned at adapter sleeve, and the other end of described connector is provided with the tapped bore that can match with the bolt of fixing lift car steel wire; Every group of steel wire tension equalizer comprises support baseboard and for regulating the control apparatus of distance between the screw rod adapter plate of support baseboard and elevator, described support baseboard is positioned at the screw rod adapter plate top of elevator, and is provided with the second through hole that several pass for connector.
For the steel wire tension balancer of lift car, it also comprises hydraulic hand-pump and hydraulic synchronizing valve, described hydraulic synchronizing valve is communicated with hydraulic hand-pump, described linear telescopic mechanism is oil cylinder, the piston of described oil cylinder is connected with expansion link, and the oil cylinder of every group of steel wire tension equalizer is communicated with hydraulic synchronizing valve.
The end of described expansion link is connected and refers to removable connection with one end of connector.
The end of described expansion link is provided with dovetail furrow, and one end of described connector is provided with the projection that can match with dovetail furrow.
The second through hole of described support baseboard is also provided with lining near outer end one side of adapter sleeve.
Described control apparatus comprises many bolts, and the bottom of every bolt is through the hole of support baseboard, and is tightened on bolt and is positioned at respectively end face and the bottom surface of support baseboard with two nuts.
Although the steel wire tension balancer of this structure has good result of use above, still has the following disadvantages:
1, because each oil cylinder is connected with hydraulic hand-pump and hydraulic synchronizing valve by oil pipe respectively, process oil pipe and hydraulic synchronizing valve like this, the length that adds oil pipe is inconsistent, all can cause the oil pressure of each oil cylinder inconsistent, like this in the time up pulling lift car steel wire, cause the pressure of each oil cylinder unequal, cause the tension force of lift car steel wire inconsistent.
2, in use, need to install one end of every oil pipe and hydraulic synchronizing valve, the other end is connected one by one with oil cylinder again, and split type like this mounting means is very inconvenient, complicated operation.
Summary of the invention
The technical problem to be solved in the present invention is that a kind of uniform tension in order of the lift car steel wire after adjustment, steel wire tension balancer for lift car simple to operation of guaranteeing is provided.
Technical scheme of the present invention is, a kind of steel wire tension balancer for lift car with following structure is provided, comprise base plate and multiple oil cylinder, one end of each oil cylinder is all fixed with the upper surface of base plate, in described base plate, be provided with the oil circuit that is communicated with each oil cylinder, described each oil cylinder is communicated with by the oil circuit in base plate, and described base plate is provided with the hydraulic fluid port being communicated with oil circuit, and the piston rod bottom of each oil cylinder is provided with the bindiny mechanism that can match with the bolt of fixing lift car steel wire.
Described bindiny mechanism comprises and the first connector of the piston rod axial limiting of oil cylinder and the second connector, described the first connector and the second connector axial limiting and circumferentially rotatable screwing with the bolt of fixing lift car steel wire.
Described the first connector and the second connector axial limiting and circumferentially rotatably refer to, it also comprises bolt, described the first connector is provided with centre hole, the top of described centre hole is the dovetail furrow matching with the projection of the piston rod of oil cylinder, middle part be can bolt head cavity, bottom be can bolt the through hole that passes of screw rod, the center of the second connector is provided with tapped bore, outer wall is provided with annular knurl, the screw rod of described bolt screws through centre hole and the second connector, after described bolt and the second connector screw, can circumferentially rotate with the first connector.
Adopt after said structure, the present invention compared with prior art, has the following advantages:
1, because each oil cylinder is communicated with by the oil circuit on base plate, like this when pressure oil is during from oil circuit oil-feed, the piston of each oil cylinder upwards promotes under the condition of same pressure, be that the thrust that is subject to of the piston of each oil cylinder is all consistent, the lift car steel wire with differential tension being connected with each piston rod is also upwards stretched, the steel rope that tension force is less moves up distance greatly, and the steel rope that tension force is larger moves up apart from little, finally reaches the uniform tension in order of lift car steel.
2, in use, saved original multiple-tubing string and hydraulic synchronizing valve, reduced costs; Each oil cylinder and base plate are always integral type, without removing and installing, simple to operate and convenient.
As improvement, described bindiny mechanism comprises and the first connector of the piston rod axial limiting of oil cylinder and the second connector, described the first connector and the second connector axial limiting and circumferentially rotatable screwing with the bolt of fixing lift car steel wire.Make like this first connector and the second connector relatively rotate, but can not move axially, in use, the bolt that can guarantee piston rod and lift car steel wire can axially drive flexible up and down, and can normally screw or unclamp, handled easily person operation, increases efficiency.
Described the first connector and the second connector axial limiting and circumferentially rotatably refer to, it also comprises bolt, described the first connector is provided with centre hole, the top of described centre hole is the dovetail furrow matching with the projection of the piston rod of oil cylinder, middle part be can bolt head cavity, bottom be can bolt the through hole that passes of screw rod, the center of the second connector is provided with tapped bore, outer wall is provided with annular knurl, the screw rod of described bolt screws through centre hole and the second connector, after screwing, described bolt and the second connector can circumferentially rotate with the first connector, this mode bolt plays the first connector and the second connector axial limiting and circumferential rotating effect, and adopt removable connection, installing/dismounting and use are all very convenient.
