As shown in fig. 1-5, the present invention provides a through passage service support for supporting an upper step and a lower step in a split-type step assembly, comprising: a first member 100, a positioning pin 200, and a second member 300; the first component 100 is used for connecting a lower pedal and limiting the lower pedal, the second component 300 is used for connecting the upper pedal and limiting the upper pedal, the first component 100 and the second component 300 are connected into a whole through a pin shaft, the first component 100 and the second component 300 rotate by taking the pin shaft as a rotating shaft, and the positioning pin 200 is positioned between the first component 100 and the second component 300 and used for limiting and positioning the first component 100 and the second component 300. This structural design can realize making into split type structure with the maintenance support, and its volume is more small and exquisite portable. When any one of the first member 100, the positioning pin 200 and the second member 300 is worn or bent and deformed by the gravity of the upper pedal and the lower pedal after a long time use, the replacement of the members can be easily performed. The number of the maintenance supports is not less than one, and the maintenance supports are made of stainless steel or aluminum alloy. The upper pedal and the lower pedal which are opened can be opened more stably by adopting the support with at least one point position, the safety of maintenance of personnel is improved, and meanwhile, the overall mechanical property can be improved by adopting aluminum alloy under the condition of considering light weight. The material is stainless steel, so that the corrosion resistance of the steel can be better improved.

The front end of the first component 100 is provided with a lower pedal clamping part 110 which is used for limiting the front and back deflection position of a lower pedal and clamping and positioning the lower pedal, and the middle of the first component 100 is provided with a positioning pin hole for the left and right sliding of the positioning pin 200; the second member 300 includes: a guide portion 310 and a positioning portion 320; the guide portion 310 is used for guiding the upper pedal so that the upper pedal slides towards the positioning portion 320; the positioning part 320 is used for attaching the upper pedal to limit the spatial sliding and positioning of the upper pedal, and the second component 300 is provided with a semicircular groove for the left and right sliding of the positioning pin 200.

The positioning pin holes of the first member 100 and the semicircular grooves of the second member 300 are overlapped in spatial position, and the projections are positioned on the same plane, so that the positioning pins 200 can smoothly slide between the first member 100 and the second member 300. The positioning pin 200 slides left and right, so that the first component 100 and the second component 300 can mutually rotate to adjust the included angle between the two components to better clamp the lower pedal and limit the upper pedal at the same time; in addition, the first member 100 and the second member 300 can be limited to be located at fixed positions by the left-right sliding movement of the positioning pin 200, and the rotation between the two members can be prevented.

The positioning pin 200 includes: the stop portion 210 and the working portion 220 are connected into a whole through screws, the stop portion 210 is respectively located at two sides of the first component 100 to prevent the positioning pin 200 from coming off the first component 100, and the working portion 220 is located between the first component 100 and the second component 300 and slides between the first component 100 and the second component 300.

The working part 220 has a concave part and a convex part, and when the first component 100 and the second component 300 need to be limited and locked, the convex part of the working part 220 is arranged between the first component 100 and the second component 300; when the first member 100 and the second member 300 need to be movable with each other, the recess of the working portion 220 is interposed between the first member 100 and the second member 300. The shape of the convex portion of the working portion 220 of the positioning pin 200 is identical to the shape of the positioning pin hole of the first member 100. The distance from the topmost end of the concave portion to the topmost end of the convex portion of the working portion 220 is greater than the diameter of the semicircular groove on the second member 300. So that the first member 100 and the second member 300 can rotate relative to each other without touching any part of the first member 100 and the second member 300, thereby maximizing the angular range of rotational adjustability.

The through passage between the vehicle body and the vehicle body of the rail transit vehicle is designed in such a way that the opening angle of the upper pedal in the pedal assembly is less than or equal to 90 degrees, the opening angle of the lower pedal is less than or equal to 45 degrees, and the opened upper pedal or the opened lower pedal can be automatically reset due to self gravity inevitably in the opening process. When maintenance and repair of the bottom of a through-passage pedal assembly in a vehicle are required, an upper pedal of a hinge structure is manually opened, the upper pedal is connected with a vehicle body fixing piece through a fixing cable so as to be kept open, a working part 220 of an inspection support positioning pin 200 is pushed to a position where rotary adjustment can be achieved by a first component 100 and a second component 300, a stopping part 210 limits a pushing space of the working part 220, the positioning pin 200 is ensured to be always positioned in a positioning pin hole of the first component 100, at the moment, a concave part of the working part 220 of the positioning pin 200 is positioned between the first component 100 and the second component 300, the lower pedal is manually opened to clamp a lower pedal clamping part 110 of the first component 100 for inspection support, the second component 300 is used for clamping the upper pedal, the relative position between the second component 300 and the first component 100 is rotationally adjusted, so that the upper pedal slides to a positioning part 320 along a guide part 310 of the second component 300, until the upper pedal is completely jointed with the positioning part 320 of the second component 300, the position limitation of the upper pedal is realized; the working part 220 of the maintenance support positioning pin 200 is shifted to the positions of limiting and locking the first component 100 and the second component 300, and at the moment, the convex part of the working part 220 of the positioning pin 200 is simultaneously arranged in the positioning pin hole of the first component 100 and the semicircular groove of the second component 300, so that the first component 100 and the second component 300 are fixed into a whole, and the opening positions of an upper pedal and a lower pedal in the pedal assembly are further kept constantly.

After maintenance of the bottom of the pedal assembly is completed, the working portion 220 of the maintenance support positioning pin 200 is shifted to the position where the first component 100 and the second component 300 can be rotationally adjusted, the second component 300 is separated from the upper pedal by the aid of the positioning portion 320 attached to the upper pedal and slides along the guide portion 310, the second component 300 is completely separated from the upper pedal, meanwhile, the lower pedal connecting portion 110 of the first component 100 is separated from the lower pedal, and accordingly maintenance support can be separated from the lower pedal and the upper pedal at the same time.
