Abstract

A kind of elevator speed-measuring device, comprises some sensors being arranged at hoistway inwall along hoistway height direction, a signal source being arranged at car side wall and described sensor relative position; Described sensor is optical sensor and evenly distributed along cage operation track, and described signal source is the miniature light sources of points of proximity light.The utility model adopts similar smooth grille structure to carry out velocity measuring, and degree of accuracy is high.

Description

A kind of elevator speed-measuring device
Technical field
The utility model relates to a kind of elevator speed-measuring device, belongs to elevator and manufactures field.
Background technology
Elevator is just more and more extensively applied in life, and the security of elevator also more and more by the design of elevator, manufacturing firm pay attention to, the travelling speed examination and controlling of lift car is one of most important link in elevator safety monitoring.The travelling speed that the elevator car speed of current routine detects often through detecting traction machine or traction sheave realizes, and precision is not high.
Utility model content
The utility model, for solving prior art problem, provides the speed measuring device that a kind of structure is simple, precision is high.
The technical solution of the utility model is: a kind of elevator speed-measuring device, comprises some sensors being arranged at hoistway inwall along hoistway height direction, a signal source being arranged at car side wall and described sensor relative position; Described sensor is optical sensor and evenly distributed along cage operation track, and described signal source is the miniature light sources of points of proximity light.
As preferably, described miniature light sources is out the light hole in car side wall.
As preferably, described light hole is mounting hole, and described mounting hole is perpendicular to cage operation direction.
As preferably, the width of described mounting hole is not more than the width of described sensor.
As preferably, described light hole is embedded with condenser, and the focus of described condenser is positioned on the workplace of described sensor.
As preferably, described light hole is communicated with ventilation unit.
Because traction machine is connected with car by soft wirerope with traction sheave, because wirerope has certain ductility, its structure mostly also is strand cable processed, and the speed therefore between traction sheave and car often there are differences.
This speed measuring device adopts the optical sensor be arranged in a large number on cage operation track as detecting sensor, adopt the pointolite be arranged on car as signal source, adjacent photosensors receives the mistiming of signal source signal, in conjunction with distance fixing between adjacent photosensors, the speed of car can be calculated.Because car is from the little space comparatively closed as, therefore car self is inevitable with light fixture, hoistway is a space equally comparatively closed simultaneously, there is not other light sources, therefore, in hoistway, when car normally runs, the light fixture in car is unique light source, as long as now open a light hole at car side wall, the function of pointolite can be realized.The light causing light hole to irradiate for avoiding rock of car cannot accurately irradiate on optical sensor, and light hole can be designed to mounting hole or the rectangular opening of vertical car traffic direction.For promoting degree of accuracy further, condenser can be set up in light hole, the light passed through being converged to the workplace that point-like or linearity fall within sensor in light hole.
In sum, the utility model has the following advantages:
1, adopt similar smooth grille structure to carry out velocity measuring, degree of accuracy is high;
2, adopt car own illumination equipment, structure is simple.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1, hoistway, 2, car, 3, optical sensor, 4, light hole.
Embodiment
With embodiment, the utility model is described in further detail below.
Embodiment one:
A kind of elevator speed-measuring device, comprises some sensors being arranged at hoistway 1 inwall along hoistway 1 short transverse, a signal source being arranged at car 2 sidewall and sensor relative position; Sensor is optical sensor 3 and evenly distributed along car 2 running orbit, and signal source is the miniature light sources of points of proximity light, and miniature light sources is out the light hole 4 in car 2 sidewall.Light hole 4 is embedded with condenser, and the focus of condenser is positioned on the workplace of sensor.Light hole 4 is mounting hole, and mounting hole is perpendicular to car 2 traffic direction, and the width of mounting hole is not more than the width of sensor.Light hole 4 is communicated with ventilation unit, and the moving air that this structure is convenient to ventilation unit and is provided cleans in light hole 4, avoid light hole 4 to be blocked by laying dust and cause detection inaccurate.
This speed measuring device adopts the optical sensor 3 be arranged in a large number on car 2 running orbit as detecting sensor, the light adopting self illumination device in car 2 to be irradiated by light hole 4 is converted into the horizontal linear that irradiates in optical sensor 3 workplace as signal source through condenser, adjacent photosensors 3 receives the mistiming of signal source signal, in conjunction with distance fixing between adjacent photosensors 3, the speed of car 2 can be calculated.When in car 2 nobody time, car 2 interior lighting device can be closed because of power saving, now optical sensor 3 also can close synchronously with saves energy.
