Embodiment 1

[0038] see Figure 1 to Figure 9 , the door machine guide rail involved in this embodiment is a single door guide rail, the cross section of the closing body 1 is a rectangle with the long side a vertically arranged, and the joint part 10 connecting the end of the closing body 1 is welded by seam welding.

[0039] A short side b or two short sides b extending horizontally of the rectangle adopt rounded corners for transition. The joint part 10 is located on the long side a or the short side b.

[0040] In this example, the joint part 10 is located on the long side a.

[0041] At the same time, according to different requirements, a carrying portion 11 with a protruding surface is provided on the outside of one long side a or two long sides a of the rectangle, and the carrying portion 11 is located in the middle of the long side a.

Embodiment 2

[0043] see Figure 10 to Figure 15 , the door machine guide rail involved in this embodiment is a double door guide rail, the cross section of the closing body 1 is a horizontally arranged I-shape, and the horizontally arranged I-shape includes a first vertical part c and a second vertical part c located on both sides. part d, an upper connecting part e and a lower connecting part f for closed connection of the upper and lower ends of the first vertical part c and the second vertical part d, wherein the upper connecting part e and the lower connecting part f are respectively facing outward The inner recess is set, and an upper recessed area g and a lower recessed area h are formed.

[0044] In this example, the upper connection part e and the lower connection part f are arranged symmetrically.

[0045] The upper recessed area g and the upper parts of the first vertical portion c and the second vertical portion d on both sides form the first protrusion i and the second protrus...

Abstract

The invention relates to a door motor guide rail of an elevator. The door motor guide rail comprises a guide rail body, wherein the guide rail body is a closing body which is formed by bending a steel strip through a cold bending machine in a head and tail connecting way; the interior of the closing body is of a hollow structure. The door motor guide rail has the advantages that by utilizing the cold bending machine to bend and form, the surface treatment on the formed guide rail is not needed; the number of procedures is reduced, the cost is reduced, and the environment-friendly and high-efficiency effects are realized; the variety of products is diversified, the limitation to product material is avoided, and the replacement and maintenance are very convenient.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a door machine guide rail of an elevator. Background technique [0002] In the prior art, the door machine guide rails of elevators are mostly solid cold-drawn products. After the guide rails are formed, the surface needs to be further processed. The process is complicated, the efficiency is low, the cost is high, and there are high energy consumption and pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved door machine guide rail of an elevator, which is bent and formed by a cold bending unit, without the need for surface treatment of the formed guide rail, reducing procedures and costs. Environmentally friendly and efficient, while the variety of products is diversified, the product material is not limited, and the replacement and maintenance are very convenie...
