Abstract
An elevator belt monitoring apparatus includes a housing for receiving an elevator belt and a plurality of screws or pins which are operable to pierce the belt and the spaced parallel cords arranged within the belt. One screw or pin engages each cord. A plurality of bridge contacts are connected with adjacent pairs of screws or pins and signal contacts are connected with the screws or pins adjacent to the outer edges of the belts. The signal contacts are connected with a monitoring device which sends and receives signals to the contacts to provide an indication of the condition or deterioration of the belt.
Claims25
An elevator belt monitoring system, comprising
- (a) a housing including a bottom portion configured to receive a portion of an elevator belt arranged in a plane and containing an array of parallel cords and a top portion removably connected with said housing bottom portion, said housing bottom portion containing a plurality of openings arranged in an array aligned with the array of parallel cords, respectively, said plurality of openings having parallel axes arranged normal to said plane containing the array of parallel cords;
- (b) a plurality of parallel belt-piercing devices arranged within said plurality of openings, respectively, each belt-piercing device in the plurality of parallel belt-piercing devices comprising a screw configured for guidance by and displacement within a respective opening of the plurality of openings along a respective opening axis to pierce a respective cord within the elevator belt when said screw is driven by a driving device;
- and
- (c) a plurality of contacts connected with said plurality of parallel belt-piercing devices, said plurality of contacts including a pair of signal contacts and a plurality of bridge contact assemblies, said plurality of bridge contact assemblies connecting selected pairs of belt-piercing devices from the plurality of parallel belt-piercing devices.
An elevator belt monitoring system, comprising
- (a) a housing for receiving a portion of an elevator belt containing an array of parallel cords;
- (b) a belt holding plate arranged in said housing, said belt holding plate retaining the array of parallel cords in a plane and containing an array of openings aligned with the array of parallel cords, respectively, said array of openings having parallel axes arranged normal to said plane containing the array of parallel cords;
- (c) a plurality of parallel pins arranged within said housing, each pin in the plurality of parallel pins being configured for guidance through a respective opening of the array of openings in said belt holding plate along said opening axis to pierce a respective cord of the parallel cords within the elevator belt;
- and
- (d) a plurality of contacts connected with said plurality of parallel pins, said plurality of contacts including a pair of signal contacts and a plurality of bridge contacts, wherein said plurality of bridge and pair of signal contacts each contain an opening for receiving a pin from the plurality of parallel pins and each of said plurality of bridge contacts connects selected pairs of pins from the plurality of parallel pins.
A contact assembly for an elevator belt monitoring system, comprising
- (a) a belt-piercing device configured to penetrate a cord within a portion of an elevator belt arranged in a plane;
- (b) a guide assembly containing a through-opening for receiving and guiding a belt-piercing device along an axis of said through-opening arranged normal to the plane through the elevator belt into contact with the cord;
- and
- (c) a contact connected with said belt-piercing device, said contact having one of a planar and L-shaped configuration.
