Embodiment 1

[0031] Example 1: In figure 1 In the shown embodiment, a head ladder of the present invention mainly improves the fixing method of the guide rail in the head ladder of the escalator in the prior art, and replaces the common one in the existing design with a vertical frame 1 The side panels and the vertical frame 1 are welded or bolted by a number of interlaced reinforcing rods 11 . In order to increase the connection points with the guide rail 5 so as to improve the accuracy and stability of the track of the guide rail working surface, the vertical frame 1 is fixedly connected with the connecting rod 2 and the support plate 3, and the guide rails 5 of the head ladder are fixedly welded on the support plate 3 On the connecting rod 2, the vertical frames 1 on the left and right sides are connected by three horizontal beams 4, so that the entire head ladder path is integrated into a large frame, so that it can be easily connected and installed with the truss, so that the head la...

Embodiment 2

[0033] Embodiment 2: as Figure 10 A kind of escalator shown, comprises truss 73, upper head stairway 71 and lower head stairway 72 connected with truss 73, handrail drive part 41, described upper and lower head stairway 71,72 The structure is the same as the head ladder of the frame structure of Embodiment 1, so the head ladder has good rigidity and stability, and the cross guide rail 6 of the lower head ladder can realize a smooth transition. In particular, because in the entire ladder system of the escalator, the roller wheel pressure of the traction chain on the guide rail arc section of the step traction chain of the upper head ladder road 71 is the largest, the vertical frame 1 of the upper head ladder road An upright reinforcing rod 11 is arranged on both sides of the guide rail arc section of the step traction chain, and the lower end of the upright reinforcing rod 11 is connected with a horizontal reinforcing rod 11 (for details, refer to image 3 ), to effectively i...

Abstract

The invention discloses a head ladder way and an escalator thereof. The head staircase way comprises vertical frames which are parallel on the left and right sides, a plurality of connecting rods and a plurality of bearing plates; the vertical frames are formed by a plurality of stiffeners which are staggered mutually; the vertical frames on the left and right sides are connected integrally through at least two horizontal beams inbetween; the bearing plates are fixedly connected with the vertical frames and the connecting rods; and each guide rail of the head ladder way is fixedly connected with the bearing plates and the connecting rods. In the escalator adopting the head ladder way of framed structure, the vertical frames on the two sides of the head ladder way are provided with horizontal connecting plates for mounting the bearings of balustrade driving parts respectively and oblong assembly holes are formed on the connecting plates. The rigidity and stability of the head ladder way are obviously improved by adopting the head ladder way of framed structure; and the escalator changes the assembly mode of the bearing bases of the driving parts, so the arrangement is convenient and the head ladder way is prevented from deforming by force.

Description

technical field [0001] The present invention relates to the technical field of escalators, in particular to a head ladder adopting a frame structure and an escalator adopting the head ladder. Background technique [0002] In the ladder system of the escalator, the ladder roads at the upper and lower ends are called the upper head ladder road and the lower head ladder road, and the two are collectively called the head ladder road. The head ladder mainly includes guide rails supporting traction chains and steps, and supporting members for positioning, connecting and supporting each guide rail. At present, there are two types of support members in the head path of the escalator: one is to directly use the truss as the support member, that is, the guide rail is directly fixed on the truss or the support plate connected with the truss, and the other is to directly use the truss as the support member. The first uses a side plate (also known as a fishplate) as a supporting member....
