[0032] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a transportation facility, including a platform 400 and a platform door, the platform door includes a platform body 200, a screen door 300 and a platform device 100, the platform door is fixed on the platform 400, an entrance and exit 201 is provided on the platform body 200, the screen door 300 can open and close the entrance and exit 201, and the platform device 100 is installed on the side of the entrance and exit 201 in the width direction.

[0034] When the vehicle on the track 500 stops at the platform 400 , the entrance and exit of the vehicle corresponds to the entrance and exit 201 of the platform door, so that passengers can get on and off the vehicle through the entrance and exit 201 when the platform door 300 is opened.

[0035] like Figure 3 and Figure 4 As shown, the platform device 100 includes a driving mechanism, a mounting seat 3 and a dozer 2, the driving mechanism includes a first motor 1, a second motor 4 and a connecting piece, the angle between the output shaft of the first motor 1 and the output shaft of the second motor 4 is not zero, the connecting piece connects the output shaft of the first motor 1 and the housing of the second motor 4, the output shaft of the second motor 4 is fixedly connected to the mounting seat 3, and the dozer 2 is fixed on the mounting seat 3.

[0036] The first motor 1 is used to drive the dozer 2 to swing up and down along the height direction of the platform door through the connecting piece, the second motor 4 and the mounting seat 3. The extreme position of the upward swing of the dozer 2 is the standby position. In the standby position, the dozer 2 is located on the side of the entrance and exit 201 of the platform door to prevent the dozer 2 from obstructing people from passing through the entrance and exit 201.

[0037] The second motor 4 is used to drive the dozer 2 to swing in the inward and outward directions of the entrance and exit 201 of the platform door.

[0038] The “inside” and “outside” directions of the entrance and exit 201 of the platform door refer to the direction in which the platform door is away from the track 500 , and the “outside” refers to the direction in which the platform door is close to the track 500 .

[0039] Specifically, when the entrance and exit 201 of the platform door is closed and passengers pass through the entrance and exit 201, the platform device 100 is in a standby state. When there is an obstacle at the entrance and exit 201 of the platform door, after the platform door detects the obstacle, the shield door 300 cannot be closed, and the control center first controls the first motor 1 to work, and the output shaft of the first motor 1 drives the connecting member, the second motor 4 and the mounting seat 3 to rotate around the output shaft of the first motor 1, so as to drive the dozer 2 to swing downward in the height direction of the platform door to a height relative to the obstacle.

[0040] Then, if Figure 6 As shown, the control center controls the second motor 4 to rotate, and the output shaft of the second motor 4 drives the dozer 2 to swing toward the inside of the platform door to clear the obstacles out of the entrance and exit 201 area of ​​the platform door, thereby automatically removing the obstacles and enabling the shield door 300 to close automatically.

[0041] After the shielding door 300 is closed, the control center controls the second motor 4 to rotate in the opposite direction, and the output shaft of the second motor 4 drives the dozer 2 to swing to the outside of the platform door to its original position. Then, the first motor 1 is controlled to rotate in the opposite direction, and the first motor 1 drives the dozer 2 to swing in the opposite direction in the height direction of the platform door to the standby position through the connecting piece, the second motor 4 and the mounting seat 3.

[0042] It should be noted that the existing platform door is provided with an anti-pinch detection device for detecting whether there is an obstacle at the platform door entrance 201, and the anti-pinch detection device is usually a laser detection device. Moreover, the control center can use the height and size of the obstacle detected by the anti-pinch detection device to control the number of revolutions of the first motor 1 to control the angle of rotation of the push shovel 2 in the height direction of the platform door, that is, the first motor 1 can drive the push shovel 2 to rotate to any angle and stop, and the extreme position of the push shovel 2 swinging downward is that the cleaning surface of the push shovel 2 is flush with the ground of the platform 400.

[0043] like Figure 5 As shown in the figure, it is a schematic diagram of the structure when the bulldozer 2 is rotated to be flush with the ground of the platform 400. Figure 6 This is a schematic diagram of the structure when the push shovel 2 is rotated to form an angle of 45° with the horizontal direction. The figure is only an angle example. In actual use, the push shovel 2 can be rotated to a corresponding angle according to the volume of the obstacle to clear the obstacle, so as to improve the cleaning efficiency.

[0044] In the transportation facility of the utility model, when the push shovel 2 is needed to clear the obstacle at the entrance and exit 201 of the platform door, the first motor 1 works first, and the output shaft of the first motor 1 drives the second motor 4, the connecting member and the mounting seat 3 to rotate around its output shaft, so as to drive the push shovel 2 fixed on the mounting seat 3 to swing downward to the obstacle, and then the second motor 4 works, and the output shaft of the second motor 4 drives the push shovel 2 to swing toward the inside of the platform door, so as to automatically push the obstacle out of the entrance and exit 201 area, so as to automatically clear the fault of the platform door. The platform door uses the first motor 1 and the second motor 4 to drive the push shovel 2 to clear the obstacles at the entrance and exit 201 of the platform door, realizes automatic fault removal, improves fault removal efficiency, improves operation efficiency, and reduces the workload of staff.

[0045] In one embodiment, the push shovel 2 is in a vertical state. In order to prevent the push shovel 2 in the standby position from affecting the normal passage of passengers through the entrance and exit 201, the push shovel 2 in the standby position needs to be located on the side of the entrance and exit 201, that is, the push shovel 2 is in a vertical state or tilted toward the side away from the entrance and exit 201. Compared with the push shovel 2 tilted toward the side away from the entrance and exit 201, the push shovel 2 in the vertical state rotates to the side close to the entrance and exit 201 to the obstacle at a relatively small angle, which can shorten the rotation time of the push shovel 2 and improve the efficiency of clearing faults.

[0046] In one embodiment, the connecting member includes a connecting arm 5 , which connects the output shaft of the first motor 1 and the housing of the second motor 4 .

[0047] In one embodiment, in the standby position, the mounting base 3 is located directly in front of the output shaft of the first motor 1, and the second motor 4 is located on the side of the mounting base 3 away from the entrance 201 of the platform door. The connecting arm 5 includes a first arm and a second arm with a non-zero angle, one end of the first arm is connected to one end of the second arm, the other end of the first arm is connected to the output shaft of the first motor 1, and the other end of the second arm is connected to the housing of the second motor 49.

[0048] In one embodiment, the first arm extends along the axial direction of the output shaft of the second motor 4 , and the second arm extends along the axial direction of the output shaft of the first motor 1 .

[0049] In one embodiment, the connecting member further includes a first connecting seat 6, the output shaft of the first motor 1 is connected to the first connecting seat 6, the minimum width of the first connecting seat 6 is greater than the diameter of the output shaft of the first motor 1, and the connecting arm 5 connects the first connecting seat 6 and the housing of the second motor 4. Since the minimum width of the first connecting seat 6 is greater than the diameter of the output shaft of the first motor 1, the outer surface area of ​​the first connecting seat 6 is large, which facilitates the fixed connection of the connecting arm 5 to the first connecting seat 6.

[0050] In one embodiment, the connecting arm 5 is welded to the first connecting seat 6 .

[0051] In one embodiment, the first connecting seat 6 is cylindrical, the axis of the first connecting seat 6 is in the same straight line as the axis of the output shaft of the first motor 1, and the connecting arm 5 connects the side wall of the first connecting seat 6 and the housing of the second motor 4. Compared with the connecting arm 5 being fixed on the end face of the first connecting seat 6, the distance between the outer wall of the first connecting seat 6 and the housing of the second motor 4 in the extension direction of the output shaft of the second motor 4 is smaller, which can reduce the length of the connecting arm 5, thereby improving the overall structural strength of the connecting arm 5. Moreover, compared with setting one end of the connecting arm 5 between the mounting seat 3 and the first connecting seat 6, when the connecting arm 5 is set to the side of the first connecting seat 6, the mounting seat 3 and the first connecting seat 6 can be arranged more compactly to reduce the occupied space of the platform device 100.

[0052] In one embodiment, the station device 100 further includes a protective cover 8 , and the first motor 1 is installed in the protective cover 8 to prevent the housing of the first motor 1 from contacting rainwater, thereby reducing corrosion and increasing the effective service life of the first motor 1 .

[0053] In one embodiment, the connecting member further includes a second connecting seat 7, a fixing cavity opened toward one side of the mounting seat 3 is provided on the second connecting seat 7, the second motor 4 is fixed in the fixing cavity, the output shaft of the second motor 4 extends from the opening of the fixing cavity and is fixedly connected to the mounting seat 3, and the connecting arm 5 connects the first connecting seat 6 and the second connecting seat 7. Fixing the second motor 4 in the second connecting seat 7 can reduce the contact between the second motor 4 and water vapor in the external environment, thereby reducing the corrosion of the external environment to the second motor 4 and increasing the effective service life of the second motor 4.

[0054] In one embodiment, the second connection seat 7 is cylindrical, the axis of the second connection seat 7 is in the same straight line as the axis of the output shaft of the second motor 4, and the connecting arm 5 is connected to the side wall of the second connection seat 7. Compared with the other end of the connecting arm 5 being fixedly connected to the end surface of the second connection seat 7, the length of the connecting arm 5 connected to the side wall of the second connecting arm 5 is shorter, and the structural strength of the connecting arm 5 is higher. Moreover, the connecting arm 5 is located in the angle area formed by the first motor 1 and the second motor 4 arranged at an angle, which can avoid additional space in the width direction and the inner and outer directions of the entrance and exit 201 of the platform door.

[0055] In one embodiment, the mounting seat 3 includes a seat body 31 and a mounting shaft 32, the cross-sectional area of ​​the seat body 31 is larger than the cross-sectional area of ​​the mounting shaft 32, one end of the mounting shaft 32 is fixedly connected to the dozer 2, and the other end is fixedly connected to the seat body 31, and the output shaft of the second motor 4 is fixedly connected to the seat body 31.

[0056] In one embodiment, the seat body 31 is cylindrical, the axis of the seat body 31 is perpendicular to the output shaft of the second motor 4, the output shaft of the second motor 4 is fixedly connected to the side wall of the seat body 31, and the other end of the mounting shaft 32 is fixedly connected to the end face of the seat body 31.

[0057] In one embodiment, the output shaft of the first motor 1 is perpendicular to the output shaft of the second motor 4, so that the plane formed by the first motor 1 driving the dozer blade 2 to swing is perpendicular to the plane formed by the second motor 4 driving the dozer blade 2 to swing, so that the first motor 1 can drive the dozer blade 2 to swing on the vertical plane where the entrance and exit 201 is located, so that the trajectory of the dozer blade 2 when swinging up and down is more stable.

[0058] In one embodiment, the mounting seat 3, the first connecting seat 6 and the second connecting seat 7 are all prisms, and any adjacent side walls of the prisms are rounded. The side walls of the prisms are all flat, which is conducive to full contact with other connecting parts and convenient for fixed connection.

[0059] In one embodiment, two platform devices 100 are provided, and the two platform devices 100 are symmetrically arranged on opposite sides of the entrance and exit 201 along the width direction of the entrance and exit 201 to reduce the length of the bulldozer 2 of a single platform device 100, to avoid the bulldozer 2 being too long and higher than the height of the platform body 200 in the standby state, affecting the aesthetics, and also to reduce the load of a single drive mechanism, so that a small-power motor can be selected.

[0060] The driving mechanisms of the two platform devices 100 can be controlled to work separately, so that the control center can select the adjacent platform device 100 for cleaning according to the location of the corresponding obstacle.

One end face of the push blade 2 can be welded or fixed to the mounting seat 3 by threaded fasteners.

[0062] In one embodiment, a brush 21 is provided on the side of the dozer 2, and the brush 21 is arranged along the length direction of the dozer 2. The brush 21 can clean obstacles when the second motor 4 drives the dozer 2 to swing inward along the platform door. The brush 21 can be made of synthetic wool such as nylon, polyester fiber, etc. When the first motor 1 drives the dozer 2 to rotate in the height direction of the platform door until the brush 21 is parallel to the ground, the brush 21 cleans obstacles, and the brush 21 can reduce the wear between the dozer 2 and the ground, and also helps to clean fragile items with a gentle thrust.
