Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but should be considered part of the authorization specification where appropriate.

Embodiment one: as shown in fig. 1 to 10, only one embodiment of the present invention is a multifunctional platform safety door structure, which comprises a vertical column 1, a sliding block 4 arranged on the vertical column 1, and a pull rope connected with the sliding block 4, wherein a driving roller 11 is arranged at the top end of the vertical column 1, the driving roller 11 is connected with a transmission chain 2, one end of the transmission chain 2 is connected with the sliding block 4, balancing weights 31 are arranged on the transmission chain 2 at intervals, the number of the balancing weights 31 is at least two, the sliding block 4 is horizontally arranged, two ends of the sliding block 4 extend to two sides of the vertical column 1, and two ends of the sliding block 4 are connected with pull ropes.

In the invention, the upright posts 1 are arranged at the edge of a platform, a plurality of upright posts 1 are arranged at intervals, sliding blocks 4 sliding up and down are arranged on the upright posts 1, a pull rope is connected between two adjacent upright posts 1 through the sliding blocks 4, the pull rope forms a pull rope safety door, the top end of each upright post 1 is provided with a driving roller 11, each driving roller 11 is connected with a transmission chain 2, one end of each transmission chain 2 is connected with the corresponding sliding block 4, when the driving rollers 11 drive the sliding blocks 4 to ascend through the transmission chains 2, the lifting safety door is lifted to be higher than the top of a pedestrian, and waiting personnel on the platform can pass through the lower part of the pull rope to reach the rail transit train or get off the train to reach the platform; conversely, when the sliding block 4 descends to drive the pull rope to descend, the personnel between the platform and the train can be separated from flowing, and the danger that the personnel at the platform fall off the platform or get too close to the train is prevented.

The driving roller 11 is connected with a driving motor for driving the driving roller 11 to rotate, that is to say, the driving motor drives the driving roller 11 to rotate under the work of the driving motor, the driving roller 11 drives the transmission chain 2 to transmit, so as to drive the sliding block 4 to lift, and taking fig. 3 as an example, the motor rotates positively to drive the driving roller 11 to rotate clockwise, the sliding block 4 rises, and the safety door is opened; conversely, the motor is reversed, and the safety door is closed; it can be understood that the motor drives the sliding block 4 to lift, so as to complete the lifting (opening) and the lowering (closing) of the safety door.

Because stay cord length is great, the drive power of stay cord and slider can be great, in order to reduce the drive power of drive roller 11, the interval is provided with a plurality of balancing weights 31 on transmission chain 2, balancing weights 31 follow transmission chain 2 and transmit, balancing weights 31 mainly play the balancing effect to slider 4 gravity, for example, when balancing weights 31 are located the stand 1 and keep away from one side of slider 4, slider 4 rises, then balancing weights 31 descend, the gravity of balancing weights 31 has balanced the gravity of slider 4 and stay cord like this for driving motor drive the power that the slider 4 of stay cord goes up and down reduces.

Of course, the number of the balancing weights 31 is at least two, in fact, a plurality of balancing weights 31 are distributed on the transmission chain 2, and the number of the balancing weights 31 to be installed can be calculated by calculating the number and the weight of the sliding blocks 4 and the number and the weight of the pull ropes when the weight of each balancing weight 31 is known; of course, the balancing weights 31 with different specifications can be selected for installation; therefore, the lifting of the pull rope can be balanced optimally, the lifting power of the driving safety door is effectively reduced, the power of the whole platform is reduced, the lifting driving power supply of the platform door can adopt voltage below 36V, the electric leakage and shock probability is effectively reduced, and the safety is high.

In addition, the sliding block 4 is horizontally arranged, so that two ends of the sliding block 4 extend to two sides of the upright 1, two ends of the sliding block 4 are connected with pull ropes, the sliding block 4 is directly lifted on the upright 1, and because the sliding block 4 is horizontally arranged, the length of the sliding block 4 is not smaller than the width of the upright 1, so that two ends of the sliding block 4 extend to two sides of the upright 1 respectively, the two sides of the sliding block 4 can pull the pull ropes, and in this case, when the sliding block 4 is lifted, the pull ropes at two sides of the sliding block 4 are lifted synchronously; the pull ropes at two sides of the sliding block 4 tend to be balanced in tension, so that the two sides of the upright post 1 are balanced in stress and not easy to incline, the upright post 1 can be thinner and higher, the stable structure can still be ensured, two-stage lifting is not required, the higher upright post 1 can directly finish single-stage lifting of the sliding block 4, and enough opening height and stability can still be achieved; and under the condition that multistage lifting is not needed, the lifting controllability of the sliding block 4 is higher, and the inclination of the pull rope caused by the fact that the lifting speeds of the sliding blocks at the two ends of the pull rope are different can not occur.

Finally, because slider 4 can directly go up and down on stand 1, stand 1 lower extreme need not to set up too much limit structure down, then slider 4 when sliding to stand 1 below, can be nearer to ground, the lower extreme of stay cord door is nearer to ground when the stay cord descends promptly, and under many times experiments, stay cord door bottom is not higher than 15cm apart from platform ground, can effectively block the invasion thing, for example scooter, basketball, football and uncontrolled suitcase etc. effectively prevent that these foreign matters from crossing stay cord door from the platform and reaching track department and causing danger.

According to the multifunctional platform safety door structure, the balancing weight is arranged at the position of the platform door post to balance the lifting of the sliding block, so that the driving power for driving the safety door to lift is reduced, the sliding block on the upright post is lifted in a single stage, the pull ropes are pulled out at the two sides of the sliding block at the same time, so that the pull ropes at the two sides of the upright post are lifted at the same time, the two sides of the upright post are balanced and are not easy to incline or damage, the sliding block is effectively prevented from being abnormally deviated through the synchronous lifting of the pull ropes, the pull ropes are good in horizontality, and high in safety.

In the second embodiment, as shown in fig. 1 to 10, which is only one embodiment of the present invention, on the basis of the first embodiment, in the multi-functional platform safety door structure of the present invention, the counterweight 31 is provided with an additional block 32, and the additional block 32 is disposed on a side of the counterweight 31 away from the upright 1;

So that the weight 31 provided with the additional block 32 is located on the side of the upright 1 remote from the slider 4;

when the sliding block 4 is lifted to the upper limit, the balancing weight 31 which is not provided with the additional block 32 is positioned at one side of the upright 1 far away from the sliding block 4; and when the sliding block 4 descends to the lower limit, the balancing weight 31 which is not provided with the additional block 32 is positioned on one side of the upright 1 close to the sliding block 4.

Here, it is equivalent to dividing all the weight structures into constant-position weights and deflection weights; a balancing weight 31 provided with the additional block 32 is installed as a constant-position balancing weight; the balancing weight 31 without the additional block 32 is used as a deflection balancing weight; under the condition that the transmission chain 2 is straightened, the constant-position balancing weight is arranged on the transmission chain 2 and is positioned at one side of the deflection balancing weight far away from the sliding block 4.

The constant-position balancing weight and the deflection balancing weight displace along with the transmission of the transmission chain 2, wherein the constant-position balancing weight is not constant in position, but is constantly positioned on one side of the upright 1 far away from the sliding block 4, and the constant-position balancing weight always ascends and descends on one side of the upright 1 far away from the sliding block 4;

Conversely, the shifting balancing weight is that the side direction of the upright post 1 is changed along with the lifting of the sliding block 4, specifically, when the sliding block 4 is lifted up to be limited, the shifting balancing weight is positioned at one side of the upright post 1 far away from the sliding block 4 (as shown in fig. 4); and when the sliding block 4 descends to the lower limit, all the shifting balancing weights are positioned on one side of the upright post 1 close to the sliding block 4 (as shown in fig. 3).

Of course, the number of the constant-position balancing weight and the deflection balancing weight is at least one.

When the sliding block 4 is lifted to the upper limit, all the displacement balancing weights are positioned on one side of the upright 1 far away from the sliding block 4; and when the sliding block 4 descends to the lower limit, all the deflection balancing weights are positioned on one side of the upright post 1, which is close to the pull rope sliding block 4.

In the present invention, there is also an intermediate state, when the slide 4 is located between the upper limit and the lower limit, a part of the displacement balancing weight is located on the side of the upright 1 away from the slide 4, and a part of the displacement balancing weight is located on the side of the upright 1 close to the slide 4.

It should be noted that the total weight of all the constant-position counterweights is greater than that of all the deflection counterweights, so that no matter the slider 4 is lifted or lowered, a force exists on the side of the upright 1 away from the slider 4, which can balance the gravity of the slider 4 and the pull rope.

Moreover, the sum of the total mass of the displacement balancing weight and the mass of the sliding block 4 (including the pull rope) is larger than the total weight of all the constant-position balancing weights, so that when the sliding block 4 is lowered to the lower limit, the constant-position balancing weights are insufficient for pulling the sliding block 4 to rise, the sliding block 4 is prevented from rising abnormally when a motor is in fault, and the safety door is opened abnormally.

And the sum of the total weight of all the constant-position balancing weights and the total weight of all the deflection balancing weights is larger than the mass of the sliding block 4 (including a pull rope), so that when the sliding block 4 is lifted up to be limited, the gravity of the sliding block 4 is insufficient to fall, the sliding block 4 is prevented from abnormally falling when a motor is in fault, and a safety door is abnormally closed and pressed to pedestrians.
