Bidirectional limiting device swinging based on tension of steel wire rope

Abstract

The invention relates to a bidirectional limiting device swinging based on tension of a steel wire rope. The device comprises a base, a guide wheel rack, a guide wheel and a steel wire rope. The device is characterized in that the guide wheel rack is fixed on the base through a bearing pin roll; the guide wheel is mounted on a central shaft of the guide wheel rack through a bearing, the central shaft is fixedly connected to the guide wheel rack through a shaft lock and a screw, upper and lower sleeves are separately mounted on the upper and lower portions of the bearing pin roll on a panel of the base, the upper and lower sleeves sleeve outside buffer springs, distance sensors are separately mounted on the outer surfaces of the upper and lower sleeves, upper and lower limiting plates are separately located in positions corresponding to the upper and lower buffer springs, and the bottom ends of the upper and lower limiting plates are fixedly connected to the guide wheel rack; a tension spring is mounted on the upper portion of the guide wheel rack, and the upper end of the tension spring is connected to the base while the lower end of the tension spring is connected to the guide wheel rack; and the limiting bolt is mounted on the left upper portion of the guide wheel rack. The device provided by the invention has the advantage of preventing the steel wire rope from jumping from a slot due to an over-large rope angle or excessive wear caused by an over-small rope angle and reducing an impact vibration phenomenon.

Description

technical field [0001] The invention belongs to the field of wire rope guiding and limiting devices, in particular to a two-way motor limiting device based on the tension swing of the steel wire rope. Background technique [0002] At present, in the device for adjusting the position of the working platform by using the motor to pull the steel wire rope, the main problems faced are firstly to prevent the steel wire rope from falling out of the groove due to excessive rope angle, and secondly to ensure the precise positioning of the working platform. Most of the existing technologies simply use the steel wire rope to wrap it tightly around the drum in an orderly manner. The actual limit position is determined by the length of the steel wire rope. Corresponding position, often can not reach convenient and reliable accurate limit like this, also can't accurately monitor whether the wire rope completes the operation task simultaneously. Contents of the invention [0003] The o...

Problems solved by technology

Most of the existing technologies simply use the steel wire rope to wrap it tightly around the drum in an orderly manner. The actual limit position is determined by the length of the steel wire rope. The corresponding position, so it is often impossible to achieve a convenient and reliable accurate limit, and it is also impossible to accurately monitor whether the wire rope has completed the task
