Description
Technical Field
The utility model belongs to the technical field of the track traffic platform door, in particular to platform door base that can electrodeless adjust.
Background
At present, an I-shaped base (an upper T-shaped part and a lower T-shaped part) is commonly adopted for a subway platform door, and the lower T-shaped part of the I-shaped base is fixed with a platform plate of a station through a penetrating bolt assembly; the T-shaped upper part and the T-shaped lower part are both transversely fixed into a whole through waist bolts, and the T-shaped upper part and the T-shaped lower part are installed and positioned by vertical bolts fixedly arranged on the T-shaped lower part.
The device has the following disadvantages in practical application:
1. the I-shaped upper T-shaped part and the I-shaped lower T-shaped part are transversely fixed into a whole through waist bolts and then are positioned through vertical bolts on the lower T-shaped part. The vertical upward adjustment amount of the base needs to be increased, so that the length of the internal thread of the vertical stud is required to be as long as possible and is matched with the length of the external thread of the vertical bolt. Meanwhile, the requirement that the overall height of the base can be adjusted downwards is considered, and the height of the vertical stud cannot be too high. Therefore, the whole height of the base is reduced and limited by the height of the vertical stud, the upward adjustment is limited by the matching of the internal thread of the stud and the external thread of the vertical bolt, and enough thread matching turns must be ensured to ensure the stability of stress, so that the adjustable range of the base is small at present.
2. The I-shaped upper T-shaped part and the I-shaped lower T-shaped part are transversely fixed into a whole through waist bolts and then are positioned through vertical bolts on the lower T-shaped part. The stress is mainly generated by the prestress applied by the waist bolt to bear the whole gravity of the platform door. Because the vibration between subway tunnel sections is big, cause the nut to become flexible very easily. The vertical bolts on the lower T-shaped are used for positioning the height of the base in the vertical direction, once the waist bolts are loosened, all vertical loads of the platform door are completely born by the threads of the vertical bolts, the stress form is unreasonable, and once the threads fail, the platform door collapses to harm the driving safety of the train.
3. The lower T-shaped part of the I-shaped base is provided with two vertical bolts, the assembly requirement is higher, the vertical threads must be fixed well before the base is installed, and otherwise, the bolts cannot be installed again after the platform door is installed. At present, a large number of vertical bolts are lost in actual engineering, and a lot of potential safety hazards exist.
