Problems solved by technology

Generally, the outer surface of the step guide rail needs to be provided with a protrusion to block the step wheel. Because the two sides of the protrusion are completely bonded together, during the production process of the step guide rail, cracks will occur in the middle bending part of the protrusion, especially During the subsequent installation and use, the upper surface of the guide rail is under the action of the downward pressure of the object, and the stress is concentrated in the middle bending part of the protrusion, which is prone to damage

Embodiment Construction

[0018] The step guide rail of the escalator according to the present invention will be further described in detail through specific embodiments below.

[0019] Such as figure 1 As shown, the step guide rail of the escalator includes an integrated guide rail body, and the cross section of the guide rail body is composed of a left side 1, a left side 2, a transverse side 3, a right side 4 and a right side 5, wherein the left side 1 and the right side The two left sides 2 are parallel to each other and bonded to form a left protrusion 6, and the two right sides 4 and the right side 5 are parallel to each other and bonded to form a right protrusion 7, and the heights of the left protrusion 6 and the right protrusion 7 are the same. The two ends of the transverse side 3 are respectively connected to the lower ends of the two left sides 2 and the two right sides 4 . In addition, circular arc transitions are respectively provided at the joints of the transverse side 3 and the two le...

Abstract

The invention relates to an escalator stair guide rail. The escalator stair guide rail comprises an integral guide rail body; the cross section of the guide rail body consists of a left edge 1, a left edge 2, a transverse edge, a right edge 2 and a right edge 1, wherein the left edge 1 and the left edge 2 are bonded in parallel to form a left projection; the right edge 2 and the right edge 2 are bonded in parallel to form a right projection; and two ends of the transverse edge are respectively connected with the lower ends of the left edge 2 and the right edge 2. The projections are respectively arranged on two sides; the pressing force of an object is acted on the upper surface of the guide rail; and the acting force is dispersed, so that the middle bent parts of the projections are not easy to damage. After the stair guide rail with two projected edges is adopted, stair wheels are operated more stably; and even if single edge of the guide rail is cracked, the stair operation is not influenced.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of elevators, in particular to a step guide rail of an escalator. [0003] 【Background technique】 [0004] The pedal of the escalator needs the step guide rail at the bottom to provide support when moving obliquely upward. Generally, the outer surface of the step guide rail needs to be provided with a protrusion for blocking the step wheel. Because the two sides of the protrusion are completely bonded together, during the production process of the step guide rail, cracks will occur in the middle bending part of the protrusion, especially During the subsequent installation and use, the upper surface of the guide rail is under the action of the downward pressure of the object, and the stress is concentrated in the middle bending part of the protrusion, which is prone to damage. [0005] 【Content of invention】 [0006] In order to solve the above problems, the object of the present invention is to pro...
