[0028] In order to be able to describe the present application in detail, first, the following will be specifically described the telescopic platform door machine system of the present application.

[0029] As Figures 1 to 8The utility model provides a retractable station door machine system, including main door beam 1 and install auxiliary door beam 2 on the both sides of main door beam 1, main door beam 1 is provided with a plurality of guide grooves along its height direction, and the side of auxiliary door beam 2 close to main door beam 1 is provided with two guide blocks along the length direction of auxiliary door beam 2, and the auxiliary door beam 2 is first positioned with the guide block and guide groove when assembling with main door beam 1. Each auxiliary door beam 2 and main door beam 1 are provided with guide rail 3, that is, each door machine system includes two guide rails 3, and the two guide rails 3 are vertically arranged in the height direction of main door beam 1, thereby reducing the carrying capacity of the same horizontal part of main door beam 1, dispersing the force of main door beam 1, and thereby increasing the service life of main door beam 1.

[0030] The auxiliary door beam 2 is provided with a strip-shaped first mounting hole 21, and the first mounting hole 21 is strip-shaped, so that the height position of the fixing support 4 relative to the auxiliary door beam 2 is adjusted through the first mounting hole 21, so that the position adjustment of the auxiliary door beam 2 is realized.

[0031] The position of the first mounting hole 21 avoids the guide rail 3, and the fixing support 4 is provided with a circular connecting hole, and the bolt is fixed on the auxiliary door beam 2, and the strip-shaped first mounting hole 21 is provided along the vertical line of the height direction of the auxiliary door beam 2, so that the fixing support 4 can be adjusted up and down relative to the auxiliary door beam 2.

[0032] The main purpose of the first mounting hole 21 is to adjust the relative height between the fixing support 4 and the auxiliary door beam 2, so that the first mounting hole 21 can be vertically arranged or inclined relative to the vertical line of the height direction of the auxiliary door beam 2.

[0033] In some embodiments, the first mounting hole 21 is inclined relative to the vertical line of the height direction of the auxiliary door beam 2, and when the fixing support 4 is connected with the auxiliary door beam 2, the force between the fixing support 4 and the auxiliary door beam 2 can be dispersed horizontally and vertically on the auxiliary door beam 2. At the same time, the inclined arrangement of the first mounting hole 21 makes the relative position between the fixing support 4 and the auxiliary door beam 2 not easy to change after the fixing support 4 is installed, and if the first mounting hole 21 is vertically arranged, the auxiliary door beam 2 may be pulled down due to the excessive weight after the door body is installed on the auxiliary door beam 2, so that the relative position between the auxiliary door beam 2 and the fixing support 4 changes.

[0034] In some embodiments, the included angle between the first mounting hole 21 and the vertical line of the height direction of the auxiliary door beam 2 is 30-60°, and the most preferred is 45°, and the force between the fixing support 4 and the auxiliary door beam 2 is dispersed to the horizontal and vertical directions of the auxiliary door beam 2, which is relatively uniform.

[0035] The fixed bracket 4 has a strip-shaped second mounting hole 43 along the first direction. The horizontal position of the pad 5 relative to the fixed bracket 4 is adjusted through the second mounting hole 43. The pad 5 has a third mounting hole 51 along the second direction. The first and second directions are perpendicular to each other. In effect, the second mounting hole 43 and the third mounting hole 51 allow the auxiliary door beam 2 to be adjusted in the horizontal plane.

[0036] In some embodiments, the second mounting hole 43 extends along the telescoping direction of the auxiliary door beam 2 relative to the main door beam 1, which means that the fixed bracket 4 can be adjusted relative to the pad 5 towards the main door beam 1. The third mounting hole 51 allows the entire door operator system to be adjusted back and forth. The fixed bracket 4 extends out from both sides of the pad 5, and the third mounting hole 51 is located on the outside of the fixed bracket 4. The third mounting hole 51 is set along the back and forth direction, that is, the third mounting hole 51 is set along the width direction of the pad 5, which can reduce the length of the pad 5.

[0037] This application enables the door operator system to be adjusted within a three-dimensional system through the strip-shaped first mounting hole 21, second mounting hole 43, and third mounting hole 51, thereby reducing the height difference between the auxiliary door beam 2 and the main door beam 1 and improving the accuracy of the auxiliary door beam 2. When the guide rail 3 is installed on the main door beam 1 and the auxiliary door beam 2, the accuracy of the guide rail 3 can be improved.

[0038] Since the guide rails 3 on both sides are staggered, the first mounting holes 21 on the auxiliary door beams 2 on both sides must also be staggered, that is, one side is higher and the other side is lower. The tilting directions of the first mounting holes 21 on both sides are opposite, that is, one tilts to the left and the other tilts to the right. Of course, they can both tilt towards the main door beam 1.

[0039] like Figure 5 As shown, the fixed bracket 4 includes a first connecting section 41 and a second connecting section 42 intersecting the first connecting section 41. The first connecting section 41 and the second connecting section 42 are connected to form an L-shape, and the second connecting section 42 extends towards the auxiliary door beam 2. A second mounting hole 43 is provided on the second connecting section 42, and a circular connecting hole is provided on the first connecting section 41. Two first mounting holes 21 are provided at the connection position between the auxiliary door beam 2 and the fixed bracket 4, and the two first mounting holes 21 are parallel in the horizontal extension direction of the auxiliary door beam 2.

[0040] A first extension section 44 is provided on the side of the first connecting section 41. The first connecting section 41 contacts the auxiliary door beam 2. Therefore, only one side of the first connecting section 41 is provided with the first extension section 44. The first extension section 44 is perpendicular to the first connecting section 41 and extends towards the auxiliary door beam 2. Figure 5 As shown, the inner wall of the first extension section 44 contacts the auxiliary door beam 2. A sensor is installed on the auxiliary door beam 2, which can detect when the door moves into place.

[0041] The second connecting section 42 is provided with a second extending section 45 on one side or both sides, the second extending section 45 extends towards the first connecting section 41, the second extending section 45 on the right side extends and contacts the first extending section 44, which means that the second connecting section 42 is not only supported by the first connecting section 41, but also supported by the first extending section 44 and the second extending section 45.

[0042] The insulating plate 6 is provided on the side of the backing plate 5 away from the fixed part, the insulating plate 6 makes the whole auxiliary door beam 2 and the cross beam 7 on the top electrically insulated, the cross section of the insulating plate 6 is U-shaped. When the third mounting hole 51 of the backing plate 5 is connected with the cross beam 7 on the top through bolts, the both sides of the bolts are padded with insulating sleeves for electrical insulation.

[0043] On the other hand, the utility model provides a kind of platform door, including above-mentioned telescopic platform door door machine system and the door body being installed on door machine system, and door machine system is installed on cross beam 7.
