Shaftway stand column manufacturing method

Abstract

The invention discloses a hoistway stand column manufacturing method which comprises the steps that a metal plate is cut and blanked, and a long-strip-shaped material plate is manufactured; bending lines are set, a first bending line consistent with the length direction of the material plate is set in the middle of the material plate, the material plate is divided into an upper side portion and a lower side portion through the first bending line, the upper side and the lower side of the first bending line are each provided with a second bending line, and the outer sides of the two second bending lines are each provided with a third bending line; the third bending line divides the upper end and the lower end of the material plate into mounting parts; the mounting part is bent towards the back face along the third bending line, then the material plate is bent towards the front face along the second bending line, finally, the upper side portion and the lower side portion of the material plate are bent towards the front face along the first bending line, and a groove body is defined by the front face of the material plate; a reinforcing plate matched with the groove body in shape is placed in the groove body, a gap between the reinforcing plate and the groove body is welded, and a blank is manufactured; and the blank is subjected to surface treatment to prepare a product, so that the stand column is more compact in structure while the strength is ensured.

Description

【Technical field】 [0001] The invention specifically relates to a method for manufacturing a shaft column. 【Background technique】 [0002] In the traditional elevator manufacturing field, in order to allow the elevator to move vertically in the building, the elevator hoistway is generally constructed in the building. The traditional hoistway is a vertically arranged metal frame, so that the car used for carrying people can be The hoistway frame is vertically lifted, and the hoistway frame usually adopts a structure built with a steel frame in a technical scheme, and the column is the main support of this structure. However, the traditional column is usually made of steel and other materials. In order to ensure the strength of the hoistway frame, the overall volume of the column is relatively large, and because the shape and specification of the column is relatively simple, it occupies a large space and has poor adaptability. [0003] The present invention is based on the abo...

However, the traditional columns are usually made of steel and other materials. In order to ensure the strength of the hoistway frame, the overall volume of the columns is relatively large, and because the shape and specifications of the columns are relatively simple, they occupy a large space and have poor adaptability.
