Embodiment Construction
[0015] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0016] A kind of manufacture method of steel ladder (see Figure 1-Figure 4 ), is characterized in that, it is processed by following steps: the one, on-the-spot survey, measure the vertical height of on-the-spot steel ladder erection position and the horizontal span of steel ladder, calculate the steel ladder by the triangular relation of right triangle length, and cut two support plates according to the length; the second is to make a scribing tool, make a Z-shaped scribing tool with the width of the pedal and the height of the pedal, and the length of the two parallel segments of the scribing tool is the width of the pedal, the middle section is the height of the pedal, the middle section is perpendicular to the ...

The invention relates to a manufacturing method of a steel ladder, which is processed through the following steps: first, on-site measurement, measuring the vertical height of the erection position of the steel ladder on site and the horizontal span of the steel ladder; second, making a marking tool to The width of the pedal and the height of the pedal make a Z-shaped marking tool, the length of the parallel two parallel sections of the marking tool is the width of the pedal, the middle section is the height of the pedal, and the middle section is perpendicular to the parallel section; , draw a line, draw a reference line at the end of the support plate, take the apex of the angle between the reference line and the end edge of the support plate as the base point, align one end of the middle section of the marking tool with the base point, and align the middle section with the reference line , draw the pedal line on the welding surface of the support plate; the fourth is welding, welding the prepared pedal between the two support plates according to the marked pedal line and height line to make a steel ladder. The invention realizes the purpose of rapidly processing steel ladders according to different environmental conditions on site.
Description
technical field [0001] The invention relates to a method for manufacturing a steel ladder, which belongs to the technical field of steel ladder processing. Background technique [0002] During the equipment installation process of the concentrator, due to the constraints of the installation location of the equipment, the installation of the stairs on the equipment operation platform is limited by the installation space, the angles of the stairs installation cannot all be constructed according to the predetermined angles of the drawings, and can only be constructed according to the actual situation on site. During on-site construction, because the angle is not easy to determine, the function value corresponding to the angle cannot be determined, so it brings difficulties to the on-site operators for sheet metal blanking and construction. The usual method is to first make the stairs according to the drawings, and then modify them according to the site conditions. In most cases...
