Elevator guide rail straightening machine

Abstract

The invention discloses an elevator guide rail straightening machine which comprises a rack. A fixed support and a movable support are arranged in the rack oppositely, and the movable support is driven by a guiding driving mechanism installed on the rack to get close to or away from the fixed support; a right front collision block and a right rear collision block are arranged on the opposite inner side wall of the movable support in the operation direction of guide rails at an interval, a left lifting collision block is arranged on the opposite inner side wall of the fixed support, the outer end portion of the left lifting collision block right faces towards the middle position between the right front collision block and the right rear collision block, and an automatic material-overturning mechanism capable of overturning the guide rails to the positions where guiding arms are placed horizontally is arranged on at least one of the front side and the rear side of the rack; when the guide rails are overturned by the automatic material-overturning mechanism to the position where the protruded portions of the bent portions of the guide rails face towards the left lifting collision block, and the right front collision block and the right rear collision block are driven by the guiding driving mechanism to enable the protruded portions of the guide rails to abut against the left lifting collision block, and enable the right front collision block and the right rear collision block to impact on the front side and the rear side of the portions, arranged at the opposite sides of the protruded portions of the bent portions of the guide rails, of the guide rails to straighten the guide rails. The elevator guide rail straightening machine has the advantages of being high in working efficiency.

Description

technical field [0001] The invention relates to an elevator guide rail straightening machine. Background technique [0002] At present, the car of the van elevator realizes smooth vertical lifting by sliding up and down along the T-shaped guide rail. The structure of the T-shaped guide rail is as follows: it includes a guide rail body with a T-shaped cross section, and the guide rail body is composed of a fixed arm and a guide arm vertically arranged in the middle of the fixed arm. When the T-shaped guide rail is installed and used, the fixed arm of the T-shaped guide rail is fixed to the building, so that the guide arm of the T-shaped guide rail is slidably matched with the elevator car; smooth operation is very important. In the production process of the T-rail, the T-rail is output from the T-rail production equipment with its fixed arm facing down and the guide arm vertically upward. Due to the limitation of the T-rail production equipment, the T-rail There are more o...

Problems solved by technology

In the production process of the T-rail, the T-rail is output from the T-rail production equipment with its fixed arm facing down and the guide arm vertically upward. Due to the limitation of the T-rail production equipment, the T-rail There are more or less bending deformations such as local protrusions or depressions in the guide arm along its longitudinal direction. At present, the T-shaped guide rail is manually turned over to the state where the fixed arm is vertical and the guide arm is horizontal and horizontal, and then Manually straighten the straightness of the guide arm of the T-shaped guide rail in the above placement state. After the straightening of the guide arm is completed, manually turn the straightened T-shaped guide rail to a position where the fixed arm is horizontal and the guide arm is vertical. In the initial placement state, this manual operation method of flipping and straightening the T-shaped guide rail is not only labor-intensive for workers, but also low in work efficiency.
