Abstract
An adjustable elevator rail repair device (14) is provided with a means for forcing raised damaged areas (18) of an elevator rail (10) back into the corresponding depressions (20) of the rail surface (9). The forcing means comprises a roller (24) rotatably mounted within a wedge (22), adjustably positioned in a housing (16). A method is disclosed for repairing the damaged rail (10) comprising a calculating step to determine the amount of adjustment necessary for the rail repair device (14).
Claims19
An elevator rail repair device for repairing scored and damaged elevator rails, comprising:
- means for forcing raised damaged areas of an elevator rail surface back into corresponding depressions in said rail surface, wherein said means for forcing includes:
- a housing;
- a roller, rotatably cooperating within said housing, said roller forcing said raised damaged areas back into said corresponding depressions of the rail;
- a first cam surface disposed in said housing;
- and
- a wedge, which mounts said roller for rotation therein, said wedge having a second cam surface which slidably contacts said first cam surface of said housing.
An elevator rail repair device for repairing scored and damaged elevator rails by forcing raised damage areas of an elevator rail surface into corresponding depressions in said rail surfaces, comprises:
- a housing, having a first cam surface;
- said housing supporting
- a roller;
- which rotatably communicates with
- a wedge, comprising a second cam surface, wherein said second cam surface slidably contacts with said first cam surface of said housing;
- and
- an adjustable stop attached to said housing.
An elevator rail repair device for repairing scored and damaged elevator rails according to claim 9, wherein said housing further comprises:
- a threaded aperture for receiving said adjustable stop.
A method for repairing scored and damaged elevator rails by forcing raised damage areas of an elevator rail surface into corresponding depressions in said rail surfaces with a rail repair device comprising means for forcing raised damaged areas of an elevator rail surface back into corresponding depressions in said rail surface, comprising the steps of:
- measuring physical dimensions and parameters of the damaged rail;
- calculating a value the rail repair device must be set at to force said raised areas back into said corresponding depressions;
- adjusting the device accordingly, based upon said calculation;
- and
- moving the rail repair device across the damaged area of the rail.
A method for repairing scored and damaged elevator rails by forcing raised damage areas of an elevator rail surface into corresponding depressions in said rail surfaces with a rail repair device comprising a housing, having a first cam surface and a roller, supported by the housing, which rotatably communicates with a wedge, comprising a second cam surface, wherein the second cam surface slidably contacts with the first cam surface of the housing, and an adjustable stop attached to the housing, comprising the steps of:
- measuring physical dimensions and physical parameters of the damaged rail;
- calculating a value the rail repair device must be set at to force said raised areas back into said corresponding depressions;
- adjusting the device accordingly, based upon said calculations;
- and
- moving the rail repair device across the damaged area of the rail.
