Turning units and devices for elevator guide rails

Abstract

The invention provides a turn-over unit and device for an elevator guide rail. The turn-over unit comprises a swing arm for vertically swinging. A first groove for supporting the two sides of the horizontal end of a peripheral guide rail and a convex block for heeling the peripheral guide rail are sequentially arranged at one end of the swing arm. A step face is arranged between the first groove and the convex block, the two ends of the step face are connected with the upper side of the first groove and the lower side of the convex block correspondingly, or the two ends of the step face, the upper side of the first groove and the lower side of the convex block are integrally formed. The swing arm drives the first groove and the convex block at one end of the swing arm to ascend according to an arc-shaped path curve, and the guide rail with the horizontal end arranged downwards is placed above the convex block. The ascending convex block collides with the bottom of the outer side of theguide rail, the bottom of the guide rail bears external force, the outer side of the guide rail is jacked, and the guide rail inclines inwards. According to the technical scheme, the turn-over unit and device are simple in structure, small in occupied area, high in efficiency and low in cost, and has the characteristics of being fast and safe in turnover, and the production quality and productionefficiency are greatly improved.

Description

technical field

[0001] The invention relates to the technical field of elevator guide rails, in particular to a reversing unit and device for elevator guide rails capable of eliminating interference from the surrounding environment. Background technique

[0002] The elevator guide rail is an important part of the elevator, and the guide rails used for elevator lifting require high processing accuracy. During the flow processing of guide rails, it is often necessary to turn over the guide rails to facilitate related operations. For example: the two sides of the guide rail and the bottom surface need to be coated with anti-rust paint. First, place the guide rail with the horizontal end facing down in a "⊥" shape. Place it on the top of the guide rail in a "ㄒ" shape, so that the bottom surface of the guide rail can continue to be coated with anti-rust paint. At present, manual handling and flipping of guide rails are often used. The labor efficiency is low, and a little carel...
