Circular wedge type rope hitch combined device for elevator

Abstract

The invention relates to a circular wedge type rope hitch combined device for an elevator. The circular wedge type rope hitch combined device comprises a steel wire rope, a rope hitch plate connected with a car, a wedge block and a taper sleeve, wherein one end of the steel wire rope winds the wedge block and is then embedded into an internal taper space of the taper sleeve. The circular wedge type rope hitch combined device is characterized by further comprising a pull rod, a rubber pad, a spring, an upper bump pad, a lower bump pad and nuts; the taper sleeve and the upper end of the pull rod are connected by a hinge; the other end of the pull rod extends to the lower side through a hole in the rope hitch; the rubber pad, the upper bump pad, the spring and the lower bump pad are all serially connected to one end, positioned at the lower side of the rope hitch plate, of the pull rod from top to bottom; threads are formed at the tail end of the pull rod; two nuts are arranged on the pull rod. The circular wedge type rope hitch combined device disclosed by the invention has the beneficial effects that the vibration can be effectively relieved, so that the steel wire rope is not subject to a greater instant tensile force, and further passengers have no feeling of sharp jolt.

Description

technical field [0001] The invention belongs to the field of elevators, and in particular relates to an elevator round wedge type rope end combination device. Background technique [0002] At present, most of the used elevators in shopping malls and residential buildings are a kind of vertical elevator suitable for high-rise buildings. Elevators are used to take people or carry goods, because they are easy to use and can save a lot of manpower and time, so they are widely used in high-rise buildings. [0003] Although the traditional elevator is widely used, it also has some design defects. The connection between the wire rope head and the car top is often rigid. The car top is fixed with a taper sleeve, and there is a tapered space inside the taper sleeve. The wire rope head is wound on a wedge, and the wedge has an outer cone angle. The outer contour of the wire rope will also form a cone angle, which is embedded into the tapered space inside the taper sleeve along thi...

AI Technical Summary

Problems solved by technology

If the track is not straight, the speed changes caused by the grid voltage instability, the driving chain jumps and other harsh operating conditions, the wire rope and the car will vibrate violently, and the wire rope may generate a large instantaneous tension, which is likely to cause premature fatigue damage of the wire rope. Passengers will feel obvious bumps, feel uncomfortable, and feel unsafe. More serious accidents such as wire rope breakage, car falling, and casualties will occur.
