Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rail clamps, in particular to a rail clamp for elevator maintenance and repair. Background Art
[0002] Current elevators are all vertically transported along the guide rails by motor traction. When the elevator is under installation, maintenance and emergency rescue, the rail clamp on the elevator is used to clamp the guide rails so that the elevator stops at the current position for the staff to maintain the elevator.
[0003] A rail clamp for elevator installation and maintenance disclosed in the patent with the publication number CN218754373U includes a fixed frame. The outer shape of the fixed frame is "U" shaped. A screw hole is opened at the midpoint of the side surface of the fixed frame. A stud is arranged in the screw hole and is threadedly engaged with each other. The outer port of the screw hole is coaxially connected with a reinforcing ring. The stud extends out of the screw hole and penetrates through the reinforcing ring. A sleeve hole is penetrated through the outer side surface of the reinforcing ring. A positioning rod is arranged in the sleeve hole and is threadedly engaged with each other. The end of the positioning rod abuts against the stud.
[0004] Adopting the above scheme can ensure that the stud still maintains the clamping and fixing of the slide rail for a long time and enhance the safety of the rail clamp. However, there are certain deficiencies in the actual use of the above scheme. During the process of the clamping plate clamping the slide rail, the elevator car will drive the slide rail to generate a downward pressure on the clamping plate, and at the same time, the clamping plate will generate a downward pressure on the stud. At this time, the stud bears most of the downward pressure, which not only easily damages the external thread of the stud, shortens the service life of the stud, but also may cause the stud to bend and deform, resulting in the loosening of the slide rail in severe cases, with low safety and certain deficiencies.
