Technical field
The utility model relates to a kind of elevator safety fender guard, relate in particular to a kind of few to the hoistway space demand, avoid the elevator governor swelling device that collides.
Background technology
The velocity limiter swelling device is the annex of velocity limiter in the safety component of elevator, and in order to tension and spacing speed limiter wire rope, it is safe and reliable to guarantee that velocity limiter and safety tongs move.Along with the rising of land price, the developer is in order to save the building space, and very little with the hoistway space design installed to elevator and to be brought inconvenience.
Velocity limiter adopts parts such as expansion tightening wheel, weight, connecting panel, electric switch to connect usually at present; In the prior art, by connecting panel, swelling device is fixed on rail-sides, speed limiter wire rope passes expansion tightening wheel, after the speed limiter wire rope elongation, and the electric switch action on the swelling device, notice needs to adjust speed limiter wire rope.
Adopt the velocity limiter swelling device of present structure, in narrow and small hoistway, can produce activity all around when elevator brings into operation or stop because during the swelling device up-and-down movement, thereby the speed limiter wire rope generation that causes connecting is all around rocked, get to miscellaneous part generation noise in the hoistway sometimes, influence passenger's traveling comfort; In addition, the weight volume is big, and the motion space demand is also big, does not meet space-saving demand instantly.
Be 201020204639.9 as the patent No., name is called a kind of Chinese utility model patent of elevator speed limiter wire rope swelling device, it comprises the rope sheave Connection Block, be contained in rope sheave on the rope sheave Connection Block, walk around rope sheave and upwardly extending speed limiter wire rope, be arranged on clump weight on the rope sheave Connection Block, be arranged on permanent seat on the bottom surface, well pit bottom of elevator, be arranged on the attaching parts on the permanent seat, and the rope sheave attaching parts is arranged on the attaching parts by turning cylinder.Just there is above-mentioned shortcoming in this patent, owing to adopt clump weight, need take certain hoistway space, this swelling device is installed in rail-sides by Connection Block in addition, elevator bring into operation or when stopping owing to can producing all around activity during the swelling device up-and-down movement, thereby the speed limiter wire rope generation that causes connecting is all around rocked, and gets to miscellaneous part generation noise in the hoistway sometimes, influences passenger's traveling comfort.
Summary of the invention
The utility model has mainly solved present velocity limiter swelling device structure and can cause speed limiter wire rope to rock all around when elevator moves or stops, in narrow and small hoistway, can run into miscellaneous part and produce noise, influence the problem of passenger comfort, provide a kind of reducing to collide safe and reliable elevator governor swelling device between steel rope and the hoistway parts.
Another goal of the invention of the utility model is to solve present velocity limiter swelling device to adopt the relatively problem of shaft space occupation of clump weight, and a kind of elevator governor swelling device few to the hoistway space demand is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of elevator governor swelling device, comprise expansion tightening wheel, one has the fixedly hydraulic efficiency gear of pulling force, described hydraulic efficiency gear is fixed on the hoistway hole at the end, the hydraulic efficiency gear top has the end of stretching, and described expansion tightening wheel is fixed on the end that stretches by support.The utility model has saved weight, the connecting panel that adopts in the present velocity limiter tensioner, has the fixedly hydraulic efficiency gear of pulling force and adopt, and expansion tightening wheel is fixed on hydraulic efficiency gear top, can effectively reduce the velocity limiter swelling device like this to the demand of hoistway space.Structure of the present utility model has overcome the possibility that in narrow and small hoistway space speed limiter wire rope is got to the hoistway miscellaneous part in addition, has improved passenger's using escalator traveling comfort.
As a kind of preferred version, described hydraulic efficiency gear is installed on the base, and this base is solid to be fixed on the end, hoistway hole by screw.Hydraulic efficiency gear is installed in the end, hoistway hole by base, and it is more fastening to make hydraulic efficiency gear install.This base is fixed on the hole by setscrew at the end.
As a kind of preferred version, be connected with the touching switch on the stretching end of described hydraulic efficiency gear, be connected with support at described base, the support front end is bent to form block body portion, and described touching switch front end arranges down, and described block body portion is positioned at the below of touching switch front end.When speed limiter wire rope extends, it is downward that this hydraulic efficiency gear can spur expansion tightening wheel, and the touching switch that then is installed on the hydraulic efficiency gear stretching end also can move downward, when touching switch front end is run into block body portion, trigger touch action, notice needs to adjust speed limiter wire rope length.
As a kind of preferred version, described support is the U-shaped support, and expansion tightening wheel is installed in the U-shaped support, and described U-shaped support is fixed on the top of stretching end of hydraulic efficiency gear.This expansion tightening wheel moves with the end that stretches, and is wound with speed limiter wire rope on the expansion tightening wheel, in case rope stretch, the end that then stretches will spur expansion tightening wheel and move down.
The utility model has the advantages that: 1. the employing hydraulic efficiency gear replaces connecting panel and the weight in the present swelling device, expansion tightening wheel is installed in hydraulic efficiency gear top, overcome in narrow and small hoistway space speed limiter wire rope and got to the possibility of hoistway miscellaneous part, reduce collision noise, improved the using escalator traveling comfort; 2. simultaneously can also reduce the velocity limiter swelling device to the demand of hoistway space.
