Accompanying drawing explanation
Accompanying drawing 1 is the novel structural representation of this use；
Accompanying drawing 2 is the enlarged drawing in accompanying drawing 1 at A.
Detailed description of the invention
Below in conjunction with detailed description of the invention, summary of the invention of the present utility model is described in further detail.It should be understood that, embodiment of the present utility model is served only for this utility model and unrestricted this utility model are described, in the case of without departing from this utility model technological thought, according to ordinary skill knowledge and customary means, the various replacements made and change, all should be included in the range of this utility model.
Accompanying drawing 1 is the novel structural representation of this use；Accompanying drawing 2 is the enlarged drawing in accompanying drawing 1 at A.Wherein 1, box body；2, regulation steel wire rope component；21, threaded rod；22, compression spring；23, adjusting nut；24, regulation steel wire rope；25, pressing plate；26, limit switch；3, fixed pulley group；31, fixed pulley；4, running block；41, running block；5, bar hole；6, traction steel-cable；7, fixed plate；8, cushion；9, bearing plate；10, spandrel girder.
As shown in accompanying drawing 1,2, a kind of elevator wire rope tension automatic regulating device, including box body 1, regulation steel wire rope component 2, fixed pulley group 3 and running block 4；Regulation steel wire rope component 2 includes two threaded rods, 22, two adjusting nuts 23 of 21, two compression springs, regulation steel wire rope 24, pressing plate 25 and limit switch 26；
The lower ending opening of box body 1；Fixed pulley group 3 horizontal homogeneous is fixed on the top in box body 1；The obverse and reverse bottom of box body 1 is respectively arranged with the most evenly distributed some bar holes 5, some bar holes 5 are vertically arranged and are on same level line, the fixed pulley 31 of fixed pulley group 3 is respectively arranged between adjacent bar hole 5, and the movable pulley 41 of running block 4 is respectively arranged at and slides up and down between bar hole 5 and in bar hole 5 one to one；
The two ends, top of box body 1 offer through hole, and threaded rod 21 inserts in through hole；Compression spring 22 is respectively sleeved on threaded rod 21；Pressing plate 25 is placed on two threaded rods 21；Compression spring 22 is arranged between the top of pressing plate 25 and box body 1；Two adjusting nuts 23 are separately positioned on the threaded rod 21 above pressing plate 25；Limit switch 26 is arranged between pressing plate 25 and box body 1 top；Regulation steel wire rope 24 is around on movable pulley 41 and fixed pulley 31 successively, and its two ends are separately fixed on two threaded rods 21；
The traction steel-cable 6 of elevator is separately fixed on the movable pulley 41 of running block 4.
Also include fixed plate 7, cushion 8 and bearing plate 9；Fixed plate 7 is arranged on bottom；Cushion 8 is arranged on fixed plate 7 upper surface；Bearing plate 9 is arranged on cushion 8；The peristome of box body 1 is fixed on bearing plate 9；It is respectively arranged with, in fixed plate 7 and bearing plate 9, the through hole that traction steel-cable 6 passes.Fixed plate 7 is fixed on the spandrel girder 10 of elevator, and spandrel girder 10 is I-steel or channel-section steel structure.Cushion 8 is two pieces.
This utility model has used movable pulley 41 and the combination of fixed pulley 31, so the half that pulling force is traction steel wire pulling force of regulation steel wire rope 24 end, and the tension force of every steel wire rope is the most equal.This structure has also used cushion 8 and compression spring 22 flexible member, whole elevator mechanism plays the effect of secondary shock-absorbing protection, substantially increases the comfortableness taken.
Limit switch 26 is installed between the upper surface and pressing plate 25 of box body 1, when certain root of traction steel-cable 6 ruptures or seriously stretches when, the weight of whole lift car or counterweight will be carried out load-bearing by the traction steel-cable 6 of less radical, thus the left and right power on traction steel-cable 6 that acts on will become big, to such an extent as to the pulling force of regulation steel wire rope 24 end becomes big.Pulling force becomes big and acts on bigger power on pressing plate 25 by adjusting nut 23, so that pressing plate 25 overcomes compression spring 22 to move downward, touches limit switch 26.The safety return circuit series connection of limit switch 26 and whole elevator so that apparatus for controlling elevator jerk also sends warning, overhauls with guide maintenance personnel.Therefore the malfunctioning warning system of all setting out of any traction steel-cable 6 in this device, considerably increase the safety and reliability of elevator.
The screw rod of steel wire rope 24 end can be regulated by adjusting nut 23 to stretch situation, to reach each pulley substantially position near box body 1 bar hole 5 center of running block 4, provide enough activity spaces to running block 4.
The example figure that this utility model is given is mounted in the situation on elevator(lift) machine room spandrel girder 10, and this device also can be arranged on elevator car roof flexibly, on counterweight frame, or other position of elevator hoistways.A kind of elevator wire rope tension automatic regulating device of the present utility model, structure is ingenious, flexible for installation, comfortableness and reliability high.
