Description

The traction system of elevator
Technical field
The present invention relates to the technical field of elevator, a kind of specifically traction system of elevator.
Background technology
The lifting process of elevator be sequentially wound by traction steel-cable the driving wheel of traction machine, the directive wheel of car and To pouring weight to roller, so as to drive the lifting of car by the frictional force between driving wheel and traction steel-cable.And elevator is made For special equipment, it examines the life safety that passenger is directly related to using the security of process, therefore for elevator reparing and dimension The requirement of shield is higher, i.e., its frequency safeguarded is high, parts service life is short, and the replacement frequency of consumable accessory is high.And elevator is being tieed up Need to lock car and to pouring weight during shield, consequently facilitating traction steel-cable releases, realize the directive wheel to all parts Overhauled or changed, and in the overhauling elevator of prior art, after the completion of the maintenance of its directive wheel or replacing, the traction steel wire When rope resets, traction steel-cable and the risk of directive wheel dislocation be present, i.e. traction steel-cable slips out of directive wheel, thus makes to drag Draw that the rotating shaft of steel wire rope and directive wheel is stuck, or cause the rotating shaft of directive wheel constantly to cause the two with traction steel-cable friction The premature breakdown of parts.
Further, since traction steel-cable is during the driving wheel around traction machine, it is desirable to driving wheel and traction steel wire Possess certain frictional force between rope, thus driving wheel by traction steel-cable drive car lift, and traction steel-cable in order to Meet that needs coat overcoat to the technological requirements such as antirust, anti-corrosion on its top layer again, described overcoat can cause traction steel-cable Frictional force between driving wheel reduces, and reduces tractive force.As can be seen here, it is above-mentioned between traction steel-cable and driving wheel Frictional force and traction steel-cable top layer in itself protect this 2 points requirement contradiction to be present.In the prior art can only be at the two Between compromise and consider, that is, the requirement of shelter for sacrificing part meets the requirement of the frictional force of traction steel-cable.
The content of the invention

Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
The present invention provides a kind of traction system of elevator, and it includes traction machine 1, the traction steel being installed in elevator hoistways Cord 2 and located at the lower section of traction machine 1 to pouring weight 3, it is characterised in that:One end of traction steel-cable 2 and the inwall of elevator hoistways Fixed, for the other end of traction steel-cable 2 with being fixed to pouring weight 3, the center section of the traction steel-cable 2 is surrounded on car successively It is described between pouring weight 3 and driving wheel 1.1 and car 4 on the directive wheel 4.1 of 4 bottoms and the driving wheel 1.1 of traction machine 1 The surface treating machine handled the top layer of traction steel-cable 2 is respectively provided between directive wheel 4.1 and driving wheel 1.1 Structure;
Described surface disposal facility includes being used for the spray body 5 and use in the surface spraying wax layer of traction steel-cable 2 In the paraffin removal mechanism 6 for removing the surface wax layer of traction steel-cable 2, described paraffin removal mechanism 6 and spray body 5 are along traction steel-cable 2 Length direction set gradually, and paraffin removal mechanism 6 be located between spray body 5 and driving wheel 1.1.
Described surface disposal facility is fixed on the inwall of elevator hoistways or is installed on the housing of traction machine 1, and it sets The position of driving wheel is disposed adjacent to, can remove the traction steel-cable into driving wheel position by surface disposal facility Top layer paraffin, and the traction steel-cable coating last layer paraffin overcoat after driving wheel.Thus traction steel wire is realized Rope top layer protection, while can also make traction steel-cable be located at driving wheel partial frictional power it is good.
Preferably, one end of described traction steel-cable 2 is fixed with lift car rope head plate 13, lift car rope head plate 13 fixes peace On inwall loaded on elevator hoistways.
Described spray body 5 is a flush coater, and the inwall of flush coater and elevator hoistways is fixed, and the nozzle of flush coater 5.1 point to the position of traction steel-cable 2.Described flush coater can select the spraying equipment of commercially available any a paraffin. So just without repeating in detail.
Described nozzle 5.1 is at least three, and circumference of whole nozzles 5.1 along traction steel-cable 2 is uniformly distributed.
Paraffin removal mechanism 6 includes the sleeve pipe 7 being placed on traction steel-cable 2, and resistive heater 8, adding thermal resistance are provided with sleeve pipe 7 Silk 8 is electrically connected by controller 9 with power supply 10.Its operation principle be by sleeve pipe 7 heat traction steel-cable 2 so as to complete for The paraffin on the surface of traction steel-cable 2 removes.
The described lower section of sleeve pipe 7 is provided with the recovery room 11 for being used for collecting liquid paraffin, the inwall two close end position point of sleeve pipe 7 She You annular oil-recovery tank 7.1, connected between recovery room 11 and oil-recovery tank 7.1 by connecting tube 12.
Described including to pouring weight 3 is outer to pouring weight 3.1 and interior to pouring weight 3.2, and the outer bottom to pouring weight 3.1 is provided with for interior right Pouring weight 3.2 is placed in the outer lower openings in pouring weight 3.1, and traction steel-cable 2 penetrates outer counterweight from the outer top to pouring weight 3.1 Block 3.1 is simultaneously fixed with interior to pouring weight 3.2, outer to be provided with the upper opening 3.1.1 penetrated for traction steel-cable 2 to pouring weight 3.1.
The operation principle of its overhauling elevator process is:
First, locked car, driven by chain block it is reversely up to pouring weight, make car and it is outer to pouring weight no longer to draging Draw steel wire rope and act power, consequently facilitating traction steel-cable releases, in the process, it is interior to pouring weight in the effect from gravity Lower tension traction steel-cable, and drive traction steel-cable to be close to by less pretightning force on each directive wheel, then, operation Personnel carry out maintenance repair, when needing to carry out local directive wheel replacing, first pull traction steel-cable to overcome interior to pouring weight offer Less pretightning force and the part of the directive wheel that makes traction steel-cable closely need to overhaul releases with directive wheel, then complete to be oriented to The replacing of wheel, then traction steel-cable is around on new directive wheel, finally reset car and outer to pouring weight, complete maintenance.Herein During, the interior pretightning force provided pouring weight, which is only in that, overcomes the gravity of traction steel-cable itself to be used to make traction steel-cable tight It is taut, so pretightning force is smaller, pull the part that can make traction steel-cable and directive wheel to depart from by manpower.Certainly also may be used With by manual labor-saving tool completion, such as chain block, lever etc..
Preferred embodiments of the present invention are described above, but are not to be construed as limiting the scope of the invention.This hair Bright to be not only limited to above example, its concrete structure allows to change, all institutes in the protection domain of demand for independence of the present invention The various change of work is within the scope of the present invention.
