Abstract
The utility model discloses a wire rope running speed on-line detecting apparatus consisting of a wear-resistant nylon wheel, an encoder, a bearing, a bearing support and a fixing support, the fixing support is installed on a wire rope winch of which the inner is fixed with the bearing seat, the encoder is installed on the bearing seat, the bearing is installed in the bearing seat, the inner end is fixedly connected with the encoder, the outer end is connected with the wear-resistant nylon wheel and the wear-resistant nylon wheel is compressed tightly on the wire rope. The wire rope running speed on-line detecting apparatus which has a flexible and simple structure solves the difficulty that the measurement of wire rope seed is inaccurate by using a drum shaft speed measurement method and can be applied in endless-rope winches in coal mine and all endless-rope wire-rope transporting systems.
Description
Technical field
The utility model relates to a kind of wire rope travelling speed on-line measuring device that is used to detect the wire rope travelling speed, and pick-up unit of the present utility model is specially adapted to the online detection of endless rope winch wire rope travelling speed under the coal mine.
Background technology
Endless rope winch is a kind of main means of transportation that personnel or material are transported in the colliery, its running status normally whether be directly connected to the production safety and the person and property safety.For a long time, be to adopt the method that directly detects winch drum shaft speed to detect the speed of endless rope winch system always.If wire rope skids, will cause the inaccurate of measuring speed on cylinder.For whole endless rope winch transportation system, because velocity survey is inaccurate, may cause departing from of actual motion speed, cause conevying efficiency to reduce, even may be because travelling speed is too fast, cause that wire rope takes off wheel, accident such as slide down takes place, personal safety as well as the property safety can not get effective guarantee.
Summary of the invention
The purpose of this utility model provides a kind of wire rope travelling speed on-line measuring device that can accurately detect the wire rope travelling speed.
Wire rope travelling speed on-line measuring device of the present utility model is made up of wear resistant nylon wheel, scrambler, bearing, bearing seat and fixed mount, fixed mount is installed on the cable work, its internal fixation has bearing seat, and scrambler is installed on bearing seat, Bearing Installation is in bearing seat, fixedly connected with scrambler in the inner, the outer end connects the wear resistant nylon wheel, and the wear resistant nylon wheel is pressed on the wire rope.
Described scrambler is an increment type solid shaft scrambler, can link together by various methods of attachment and bearing.Wherein, simple effective method is that the axle with scrambler extend in the bearing, adopts jackscrew to be connected and fixed, and rotates synchronously to guarantee scrambler and wear resistant nylon wheel.
The utility model also fixed mount is provided with lead outlet, by lead-in wire scrambler is connected with the PLC or the control instrument such as velocity metre of outside, with the count pick up signal, by calculating the girth and the umber of pulse of pressing rope wear resistant nylon wheel, calculate the distance of wire rope walking in the unit interval, thereby draw the wire rope travelling speed that real time on-line monitoring arrives.
The utility model also is lined with elastic rubber fitting between fixed mount and cable work, for pick-up unit provides pressure, guarantee that the wear resistant nylon wheel closely contacts with wire rope all the time, prevents to skid, thereby the reliability of data is guaranteed.
The principle of work of the utility model wire rope travelling speed on-line measuring device is: the wear resistant nylon wheel compresses wire rope, drags the wear resistant nylon wheel during wire rope operation with the rope rotation, drives the rotation of incremental encoder axle by bearing.Scrambler is exported corresponding tachometer pulse, and reading by its inner direction judgment circuit sum counter of the differentiation of its sense of rotation and umber of pulse realizes.Because vibration is stronger during the wire rope operation, elastic rubber fitting is installed in the middle of fixed support and pick-up unit, for pick-up unit provides pressure, guarantee that the wear resistant nylon wheel closely contacts with wire rope all the time, prevents to skid, thereby the reliability of data is guaranteed.The outside control instrument count pick up signals such as PLC or velocity metre that use just can draw the distance of wire rope walking in the unit interval easily by calculating the girth and the umber of pulse of pressing rope wear resistant nylon wheel, thereby draw the real time on-line monitoring travelling speed of wire rope.
It is flexible that wire rope travelling speed on-line measuring device of the present utility model has structure, adaptability is strong, characteristics simple to operate, can use continuous rope wire rope transportation systems such as impractical person vehicle, road railer, the transportation of wirerope belt to apply in endless rope winch under the coal mine and all, and can be in the wire rope operation setting is installed more arbitrarily.
Wire rope travelling speed on-line measuring device of the present utility model is improving a lot aspect usability and the anti-vibration, stable, solve present employing and measured the inaccurate difficult problem of drum shaft speed mode measuring steel wire rope speed, guaranteed the material installation and the pedestrains safety of down-hole transportation.
