Horizontal movement device for hoisting machine

Abstract

The invention relates to a horizontal movement device for a hoisting machine. The horizontal movement device comprises a first guide rail pair arranged at the left side of the hoisting machine and a second guide rail pair arranged at the right side of the hoisting machine; the horizontal movement device is characterized in that the first guide rail pair comprises a first guide rail arranged on the ground and a plurality of first rolling wheels which are pivoted at the left side of a rack; an annular groove which is blocked on the first guide rail is arranged in the external surface of each first rolling wheel; each first rolling wheel is blocked on the first guide rail and moves along the direction of the first guide rail; the second guide rail pair comprises a second guide rail arranged on the ground and a plurality of second rolling wheels which are pivoted at the right side of the rack; the second guide rail is parallel to the first guide rail; the second guide rail is a plane guide rail and is provided with a supporting surface extending along the direction of the second guide rail; and each second rolling wheel is pressed on the supporting surface in a rolling way. According to the horizontal movement device provided by the invention, the requirements on the center distance of the guide rails and the precision of the guide rails are low; the requirement on the coaxial precision of the rolling wheels is low; the installation and adjustment are convenient, and the running of the device is safe and reliable.

Description

technical field [0001] The invention relates to a horizontal moving device of an elevator. Background technique [0002] Existing horizontal moving devices for elevators generally have two structures, wherein: [0003] The first structure is as figure 1 As shown, the elevator frame a1 is installed and supported on the rotating shaft a7, and the two ends of the rotating shaft a7 are pivotally mounted with a V-shaped grooved roller a2 through the bearing a8, and two parallel angular guide rails a3 are arranged on the ground a4. The V-shaped groove of the roller a2 is nested on the guide rail a3, so that the elevator can move in translation along the diagonal guide rail a3 direction; [0004] The second structure is as figure 2 As shown, the elevator frame a1 is installed and supported on the rotating shaft a7, and the two ends of the rotating shaft a7 are pivotally mounted on the roller a2 through the bearing a8. The outer surface of the roller a2 is a circumferential surf...

AI Technical Summary

Problems solved by technology

[0005] The horizontal moving devices of these two elevators have the following disadvantages: 1) The center distance between the two guide rails and the accuracy of the guide rails are high, and the center distance between the two guide rails is slightly larger or smaller, which will cause the rollers to derail easily, cause large vibrations, and guide rails are jammed and worn Serious, etc.; 2) The coaxiality of the rollers requires high precision; 3) The rollers have no upper limit, and it is easy to derail and unsafe; 4) It is inconvenient to install and adjust
