Detailed Description
in order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a method for manufacturing a linear ladder turning guide rail according to an embodiment of the present invention is shown. As shown in fig. 1, the method for manufacturing the linear ladder overturn guiding rail can comprise the following steps:
Step 101, obtaining the step width of the steps of the linear ladder, the step height of the first step and the step height of the second step.
the linear ladder is a linear stair to be provided with the seat elevator, and the step width of each step of the linear ladder is the same.
as shown in fig. 2, the tumble guide rail 21 covers the first step and the second step of the linear ladder 20, the fixed guide rail 22 covers the steps of the linear ladder 20 other than the first step and the second step, and the tumble guide rail 21 and the fixed guide rail 22 together constitute a guide rail of the stairlift.
because the size of the stairs is different, there are cases where the step height of the first step is different from the step heights of the other steps, and therefore, the step height of the first step and the step height of the second step need to be obtained.
and 102, determining the stair angle of the linear stair according to the step height of the second step and the step width of the step.
As shown in FIG. 2, the step height A2 of the second step and the step width B of the step satisfy the relationship:Alpha is the angle of the stairs; i.e. the angle of the stairs
And 103, determining the length of the longest edge of the turnover guide rail according to the step width of the step, the step height of the first step, the step height of the second step and the angle of the stairs.
As shown in fig. 2, in determining the length of the longest side of the roll over rail, the length of the roll over rail may be divided into two sections, L1 and L2.
the length of L1 relates to the sum of the step height of the first step and the step height of the second step.
The length of L2 is related to the position of the folding point P, and in order to compensate the gap between the linear ladder guide rail and the step surface, the distance between the folding point P and the edge of the first step is set as
