Hollow guide rail for guiding running direction of elevator

Abstract

The invention relates to a hollow guide rail for guiding the running direction of an elevator. The hollow guide rail comprises a hollow guide rail body formed by integrally bending/rolling, a lift carand a counterweight are installed on the hollow guide rail body, and a counterweight running guide groove and a lift car running guide face which correspond to and are matched with a counterweight guide shoe on the counterweight and a lift car guide shoe on the lift car respectively in position are formed on the hollow guide rail body. The lift car and the counterweight are guided at the same time through the hollow guide rail, the lift car moves up and down through the lift car guide shoe under the guide effect of the lift car running guide face, the counterweight moves up and down through the counterweight guide shoe under the guide effect of the counterweight running guide groove, and the movement direction of the lift car is opposite to the movement direction of the counterweight. According to the hollow guide rail for guiding the running direction of the elevator, the elevator area utilization rate is increased, the vertical mounting times of a lift car guide rail and a counterweight guide rail on site are reduced, the vibration problem of the lift car in the running period caused by inconsistent guiding perpendicularity is avoided, the complexity of mounting the lift car andthe counterweight guide rail on site is reduced, and the operation stability of the lift car is improved.

Description

technical field [0001] The invention belongs to the technical field of elevator accessories, and in particular relates to a hollow guide rail guiding the running direction of an elevator. Background technique [0002] Most of the structures of existing guide rails for elevators are as follows: Figure 1-3 As shown, the solid guide rail 3 is usually used to guide the running direction of the car 1, and the hollow guide rail 4 is usually used to guide the running direction of the counterweight 2. During use, the solid guide rail 3 and the hollow guide rail 4 are usually installed and fixed on the car 1 and counterweight 2, there are the following disadvantages: the installation occupies a large area, resulting in low space utilization of the car 1; the overall weight of the solid guide rail 3 is large, which requires high force on the elevator installation ground, and the installation and transportation process Because it is too heavy, the installation workers and transport wo...
