Example one

As shown in fig. 1 to 4, a novel subway platform screen door comprises a door frame 1 and a door body 2, wherein the door frame 1 is made of metal and is usually buried under the ground. Wherein the door body 2 slides along two opposite sidewalls of the door frame 1 (the two opposite sidewalls referred to herein are a left sidewall 11 and a right sidewall 12 in fig. 1), and the door body 2 slides in a vertical direction. In order to prevent the upper portion of the door frame 1 from blocking the up-and-down sliding motion of the door body 2, the present embodiment provides that the upper portion of the door frame 1 is in an open form, and the upper portion thereof is flush with the ground. The door body 2 generally includes a frame and glass enclosed within the frame.

In the embodiment, in the implementation form of the relative sliding between the door body 2 and the door frame 1, vertical grooves are provided on two opposite side walls (the left side wall 11 and the right side wall 12) of the door frame 1, the size of the groove is suitable for accommodating a frame of the door body 2, and the door body 2 slides along the direction limited by the groove; the setting of the recess on the door frame 1 can also play the spacing effect to the door body 2 for guaranteeing the stability of the door body 2 when sliding on the door frame 1.

The bottom of the door body 2 is provided with a horizontal sliding rail or a horizontal sliding chute 3, and in this embodiment, the horizontal sliding chute 3 is preferably arranged on the frame at the bottom of the door body 2. The horizontal sliding groove 3 is horizontally arranged along the width direction of the door body 2. A slide block 4 is connected in the horizontal chute 3 in a sliding way. In order to prevent the sliding block 4 from slipping off from the horizontal sliding groove 3, in this embodiment, the sliding block 4 is configured as an anti-slip sliding block, and the horizontal sliding groove 3 is an anti-slip sliding groove, such as a T-shaped groove, a V-shaped groove, or a dovetail groove.

The above structure discloses the basic structure of the door body 2 and the door frame 1, and the movement form of the door body 2 on the door frame 1. However, a mechanism capable of driving the door 2 to perform the up-and-down motion is not provided. Therefore, the present embodiment further includes a door driving mechanism for driving the door 2 to move, wherein the door driving mechanism is located below the door 2, that is, the door driving mechanism is also located below the ground.

The door body driving mechanism specifically comprises a driving part 5 and a connecting rod 6, wherein one end of the connecting rod 6 is rotatably connected to the slider 4, the other end of the connecting rod 6 is rotatably connected to the door frame 1, preferably, the driving part 5 is used as a linear driving mechanism, two ends of the driving part 5 are respectively rotatably connected to the connecting rod 6 and the door frame 1 (preferably, the bottom surface of the door frame 1), and preferably, the driving part 5 is connected to the middle position of the connecting rod 6.

In this embodiment, shaft holes are respectively arranged at two ends of the connecting rod 6, and the shaft holes at two ends of the connecting rod 6 are parallel to each other; meanwhile, the slide block 4 is provided with a containing groove capable of containing the end part of the connecting rod 6, and two opposite side walls of the containing groove are also provided with shaft holes. Stretch into the storage tank of slider 4 with an tip of connecting rod 6 in, make the shaft hole of connecting rod 6 tip and the shaft hole on the slider 4 align the back simultaneously, the rethread round pin axle 9 is with both cross-under, so, make connecting rod 6 rotatable through round pin axle 9 relative slider 4.

The connecting rod 6 is rotatably connected to the door frame 1 in the same manner; in the present embodiment, a first hinge base 7 is installed on a side wall (a left side wall 11 or a right side wall 12) of the door frame 1, and the first hinge base 7 may be welded or bolted to the door frame 1; meanwhile, the first hinge base 7 is also provided with a containing groove capable of containing the end part of the connecting rod 6, and two opposite side walls of the containing groove are also provided with shaft holes. The other end of the connecting rod 6 is inserted into the accommodating groove of the first hinge base 7, and after the shaft hole on the other end of the connecting rod 6 is aligned with the shaft hole on the first hinge base 7, the connecting rod 6 and the first hinge base 7 are connected together by a pin 9, so that the connecting rod 6 can rotate relative to the first hinge base 7 (i.e. relative to the door frame 1) through the pin 9.

The connecting rod 6 and the connection form of the connecting rod 6 relative to the sliding block 4 and the door frame 1 provide a motion mechanism support for the lifting of the door body 2, the motion power of the connecting rod 6 comes from the driving part 5, but the angle of the driving part 5 relative to the connecting rod 6 and the bottom surface of the door frame 1 is also changed continuously in the driving process. Therefore, in the present embodiment, a second hinge base 8 is provided in the middle of the connecting rod 6 and the bottom surface of the door frame 1, the second hinge base 8 is identical in structure to the first hinge base 7, and both ends of the driving part 5 are rotatably connected to the two second hinge bases 8 by the pin shafts 9.

As the linear driving mechanism, the driving section 5 may be selected from various types, for example, an air cylinder, a hydraulic cylinder, an electric screw, or the like.

Of course, as a shielding system, a glass isolation wall is usually disposed on the ground, a plurality of notches are formed in the glass isolation wall, one shielding door is disposed under the ground at each notch, and the door body 2 is lifted from the ground and then plugs the notch, so that the shielding purpose is achieved.

Briefly describing the working principle of the invention, the metro platform screen door of the invention is characterized in that the door frame 1 is arranged under the ground, when a train arrives at a station, the driving part 5 works, the output end of the driving part contracts, so that the length of the driving part 5 is shortened, under the pulling of the driving part 5, the upper end of the connecting rod 6 is far away from the side wall of the door frame 1, and simultaneously, the height of the upper end of the connecting rod 6 is also reduced, so that the door body 2 is also reduced, in the engineering application, the door body 2 can be completely sunk into the door frame 1 under the ground under the pulling of the driving part 5 only by setting the calculated length of the connecting rod 6, the width and the height of the door body 2, and passengers can freely pass through the door; on the contrary, when the shielding door needs to be closed, the output end of the driving part 5 only needs to be extended out, the length of the driving part 5 is increased, and under the pushing of the driving part 5, the side walls of the two connecting rods 6, which are close to the door frame 1, push the door body 2 to rise until the door body 2 extends out of the ground to block the passengers.

From the working process, when the shielding door is opened, under the condition that the lifting speed of the door body 2 is constant, the opening time of the shielding door is only related to the gap or the height of the door body 2 and is not related to the width of the door body 2, so that the width of the door body 2 can be increased to be larger, and the exchange flow and the exchange speed of passengers getting on and off the bus can be improved.

Moreover, the body 2 of the lifting type moving door body, the limbs of passengers or articles such as the top of the door body 2 are hung, due to the combined action of gravity and the lifting movement of the door body 2, the articles hung by the door body 2 can be separated from the predicament by themselves, and compared with the safety threat to people caused by the traditional side-open type shielding door in the operation process, the threat caused by the shielding door is greatly reduced.

In the use process of the structure, the weight of the door body 2 is always supported by a mechanism consisting of the connecting rod 6 and the driving part 5; especially when the link 6 is in the inclined state, the driving portion 5 is used as a connecting member between the link 6 and the door frame 1, which needs to bear a large axial pressure, and as shown in fig. 1, the door body 2 is in a state of being retracted into the door frame 1 (i.e. in a state when the shield door is opened), and the long-time maintenance of this state may affect the driving portion 5 and reduce the service life.

Therefore, in the present embodiment, support tables 13 for supporting the door body 2 are provided on both opposite side walls of the door frame 1, i.e., the left side wall 11 and the right side wall 12. The support table 13 may be an auxiliary component mounted at a later stage by welding or bolting; it is also possible to have the projection integrally formed by structural design at the time of manufacture of the door frame 1, for example in the manner used in the present embodiment.

And the driving part 5 is preferably a double-headed cylinder to facilitate the installation of the two second hinge bases 8, as shown in fig. 5.

When a train arrives at a station, the driving part 5 works, two ends of the driving part are contracted, so that the length of the driving part 5 is shortened, the upper ends of the two connecting rods 6 are close to each other under the pulling of the driving part 5, and meanwhile, the height of the upper ends of the connecting rods 6 is also reduced, so that the door body 2 is also reduced, and in engineering application, the door body 2 can be completely sunk into the door frame 1 under the ground under the pulling of the driving part 5 only by setting specific numerical values of the calculated length of the connecting rods 6, the width and the height of the door body 2, so that passengers can freely pass through the door frame; on the contrary, when the shielding door needs to be closed, only two output ends of the driving portion 5 need to extend out, so that the length of the driving portion 5 is increased, and under the pushing of the driving portion 5, the upper ends of the two connecting rods 6 are mutually far away from each other and rise in height, so that the door body 2 is pushed to rise, and the purpose of blocking passengers from passing through is achieved until the door body 2 extends out of the ground, as shown in fig. 6.

EXAMPLE III

The difference from the first embodiment is that: in this embodiment, the second hinge base 8 is slidably connected to the connecting rod 6, and the second hinge base 8 is slidably connected to the bottom surface of the door frame 1; specifically, an axial slide groove is provided on the side wall of the link 6 on the bottom surface of the door frame 1, and the second hinge base 8 is mounted on and slides along the axial slide groove.

Example four

It differs from any of the above embodiments in that: as shown in fig. 7, the present embodiment proposes a new form for realizing the sliding of the connecting rod 6 relative to the door body 2; in this embodiment, the fixing member 10 is detachably mounted at the bottom of the door body 2 in a bolt or a clamping groove manner, a through groove 101 is formed in the fixing member 10, the through groove 101 penetrates through the fixing member 10 along a direction perpendicular to the door body 2, and the length direction of the through groove 101 is parallel to the door body 2; the upper end of the connecting rod 6 is provided with an opening groove 61, the opening groove 61 receives the fixing piece 10, two opposite end surfaces of the opening groove 61 are provided with coaxial through holes 52 which are opposite to the through groove 101, and a connecting pin 102 penetrates through the through holes 52 and the through groove 101 so as to fix the connecting rod 6; the above-described structure is provided such that the link 6 can slide relative to the fixing member 10 (i.e., the door body 2) along the through-groove 101 by the connecting pin 102.
