Description

Technical Field

[0001] The utility model relates to the technical field of safety doors, in particular to a C-shaped door machine beam structure for platform doors. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] In the current rail transit platform door system or rapid transit platform door system, the door machine beam is generally used to install sliding doors, emergency door guide rails or pulley trolleys.

[0004] However, for the installation or fixation of wire ducts, position sensors, travel switches, front covers and rear covers, if the above equipment or structures need to be installed or fixed on the gantry beam, it is necessary to make holes at the corresponding positions of the gantry beam at the installation site, and then install or fix them. However, the above hole opening and installation process not only takes a lot of time and is inconvenient to install, but also requires the operator to be very familiar with the gantry beam or other structures to avoid inappropriate hole opening positions.

[0005] The existing conventional gantry crane beams are all "L" shaped, which are not optimal in terms of torsion resistance at the same unit weight. In addition, the position of the gantry crane beam of the traditional screen door is generally set near the second oblique line segment at the top of the inclined plane of "GB146.2-2020 Standard Gauge Railway Limits Part 2: Building Limits". If the "L" shaped gantry crane beam does not exceed the limit, the top box space can only be compressed or the gantry crane beam can be raised. Compressing the top box space will lead to a decrease in installation and maintainability. If the position of the gantry crane beam is raised, the door body or the hanging wheel needs to be raised accordingly, which will not only increase the amount of materials used and lead to an increase in costs, but also generate new weight and reduce the service life of the hanging wheel.

[0006] The horizontal installation angle error of the gantry machine beam is sensitive. When there is an angle deviation, under the action of gravity, the sliding door sliding on the gantry machine beam has a large resistance component, which not only causes motor power loss, but also fails to start or work normally. At the same time, the control is very complicated due to the inconsistent running resistance of the door body in the forward and reverse strokes.

[0007] With the widespread use of shielding doors, a door machine beam with high rigidity, high strength, light weight, easy installation, high maintainability, and material saving and cost reduction is particularly important. Utility Model Content

[0050] The guide rail support beam 141 is used to carry and connect the diagonal support section 13 with the guide rail guide beam 142. Its wall thickness is 2 times or more than the other wall thickness on the gantry crane beam body 1. The length of the guide rail support beam 141 is 2-5 times its wall thickness.
