Description

Technical Field

[0001] The present invention relates to a stepped lift type barrier-free passage, belonging to the technical field of barrier-free facilities. Background Art

[0002] Entering an aging society, steps are very unfriendly to wheelchair users, mainly manifested as follows: wheelchairs cannot pass through, and there are no barrier-free ramps on many platform steps; when installing a vertical elevator in an old house, there is still a half-floor staircase step from the elevator exit on the corridor corner platform to the entrance, making it difficult for wheelchairs to go up; some staircase buildings cannot install vertical elevators due to design reasons (such as two floors of commercial shops downstairs), making it inconvenient for wheelchairs to go up and down. There is still a blank in how to transform steps into barrier-free ones for existing products, and there is a lack of a barrier-free device for wheelchairs to go up and down steps. Summary of the Invention

[0003] In order to solve the problem that it is difficult for disabled people in wheelchairs to go up steps, the present invention proposes a stepped lift type barrier-free passage, which uses a lifting component to match a foldable horizontal passage. Under the control of a control system, the wheelchair and the user are lifted from the bottom of the steps to a horizontal passage flush with the top of the steps, realizing the barrier-free transformation of the steps.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0006] A lifting component, a horizontal passage and a control system;

[0007] The lifting component is composed of a fixed frame, a linear power module, a movable platform and a safety guardrail;

[0008] The fixed frame is fixed to the ground or the wall, and a linear power module and a movable platform are installed on the fixed frame, and its size is customized according to the on-site size;

[0009] One or two linear power modules are provided as required, installed in the middle or on both sides of the frame. The linear power module can preferably be a combination of a large-load screw slide table module and a servo motor. The servo motor drives the screw to drive the slide to move linearly, and the servo motor is controlled to work through the control system;

[0010] The movable platform is fixedly connected to the movable slide in the linear power module, moves up and down linearly with the slide, an accordion-type protective cover is also designed at the bottom of the movable platform, safety handles are also designed on the vertical surface of the movable platform, and the hanging ears on both sides of the back of the movable platform are movably connected to the optical rods on the fixed frame;

[0011] In a feasible design, both the entrance safety guardrail and the exit safety guardrail on the movable platform are composed of rod bodies driven by folding motors;

[0012] The horizontal passage is composed of a fixed fence, a movable fence, a connecting crossbar, a floor panel, a bottom folding motor, a protective rod, and an alignment component. The fixed fence is fixed to the wall / floor. The movable fence is movably connected to the connecting crossbar, the floor panel, and the fixed fence through hinges. A bottom folding motor is also designed at the connection between the floor panel and the fixed fence.

[0040] Embodiment 3:

[0041] As Figure 7 shown, the step-lifting barrier-free passage includes:

[0042] a lifting component 1, a horizontal passage 2, and a control system;

[0043] The lifting component 1 consists of a fixed frame 1-1, a linear power module 1-3, a movable platform 1-2, and a safety guardrail;

[0044] The fixed frame 1-1 is fixed to the ground. The fixed frame 1-1 is located in the middle of the descending part of the steps. A linear power module 1-3 and a movable platform 1-2 are installed on the fixed frame 1-1. The linear power module 1-3 and the movable platform 1-2 are arranged on one side of the wall, and their sizes are customized according to the on-site dimensions. One or two linear power modules 1-3 are arranged as required and installed in the middle or on both sides of the frame. The linear power module 1-3 can preferably be a combination of a large-load screw slide module and a servo motor. The servo motor drives the screw to drive the slide to move linearly, and the servo motor is controlled to work through the control system. The movable platform 1-2 is fixedly connected to the movable slide in the linear power module 1-3 and moves linearly up and down with the slide. An accordion-type protective cover is also designed at the bottom of the movable platform 1-2, and safety handles are also designed on the vertical surface of the movable platform 1-2. In a feasible design, the entrance safety guardrail 1-5 and the exit safety guardrail 1-6 on the movable platform 1-2 are both composed of rod bodies driven by folding motors, and the entrance safety guardrail 1-5 and the exit safety guardrail 1-6 are arranged correspondingly and are consistent with the installation direction of the steps.

[0045] Working process:

[0046] Fix the fixed frame 1-1 on the ground / wall of the step stage with appropriate vertical height (about 1 meter in vertical height, and a too-high step stage is not suitable for this solution). Fix the linear power module 1-3 with a motor on the fixed frame 1-1. The movable platform 1-2 is fixed to the slide in the linear power module 1-3 by bolts. The hanging ears on both sides of the back of the movable platform 1-2 are movably connected to the optical rods on both sides of the fixed frame 1-1. The entrance and exit safety guardrails 1-6 are installed on the edge of the vertical surface of the movable platform 1-2. An accordion-type protective cover is installed between the bottom of the movable platform 1-2 and the fixed frame 1-1. In this way, the installation of the lifting component 1 is completed.

[0047] Next, install the horizontal channel 2. First, fix the fixed fence 2-1 to the wall or the ground, then connect the connecting cross bar 2-4 to the fixed fence 2-1 and the movable fence 2-2 through hinges. Then, install the bottom folding motor 2-5 on the fixed fence 2-1 in a folded state. Finally, connect the floor panel 2-3 to the fixed fence 2-1 and the movable fence 2-2 through hinges, and connect the floor panel 2-3 to the folding arm 2-5.1 of the bottom folding motor 2-5. The protective rod 2-6 is installed at the end of the horizontal channel 2. Finally, fix the alignment component 2-7 to one side of the floor panel 2-3 close to the movable platform 1-2 to complete the installation of the horizontal channel 2.

[0048] After completing the above work, connect all motors, sensors, up / down buttons, and emergency stop buttons to the controller respectively, and set the working sequence and process of each motor and the instructions corresponding to each sensor / button according to the on-site situation. In the standby mode, the bottom folding motor 2-5 in the horizontal channel 2 is opened to make the horizontal channel 2 in a folded state, the linear power module 1-3 drops to the lowest position to make the movable platform 1-2 close to the ground, and the motors of the two safety guardrails at the entrance and exit of the movable platform 1-2 are opened to make the safety guardrails in an open state.

[0049] Taking wheelchair users as an example, the usage process is introduced as follows:

[0050] For upward use, in the standby mode, the wheelchair user pushes the wheelchair onto the movable platform 1-2 and presses the upward button. At this time, the folding motors of the two safety guardrails at the entrance and exit of the movable platform 1-2 start to work, lowering the two safety guardrails at the entrance and exit. At the same time, the bottom folding motor 2-5 in the horizontal channel 2 works to gradually open the horizontal channel 2 until the movable fence 2-2 falls on the steps and triggers the sensor to stop. After the two safety guardrails at the entrance and exit are safely lowered, the motor in the linear power module 1-3 works to drive the movable platform 1-2 to slowly rise. The bellows 1-4 at the bottom of the movable platform 1-2 gradually unfolds as it rises. When the movable platform 1-2 rises to the same height as the horizontal channel 2 and triggers the limit switch signal to stop, after one second, the alignment component 2-7 works to align and magnetically lock the movable platform 1-2 with the ground board 2-3. The motors of the exit safety guardrail and the guardrail 2-6 at the end of the horizontal channel 2 work to open the exit safety guardrail and the guardrail 2-6. After the user pushes the wheelchair onto the horizontal channel 2, reaches the top of the steps, and walks out of the horizontal channel 2, press the storage button next to the horizontal channel 2. The control system controls the alignment component 2-7 to stop working. Then, the bottom folding motor 2-5 at the bottom of the ground board 2-3 works to gradually fold the horizontal channel 2. At the same time, the guardrail 2-6 also retracts upward. The motor of the exit safety guardrail of the movable platform 1-2 works to lower the exit safety guardrail. The linear power module 1-3 starts to descend and triggers the limit stop at the lowest point. Then, the motors of the two safety guardrails at the entrance and exit lift up to make the whole enter the standby mode.

[0051] For downward use, in the standby mode, the wheelchair user pushes the wheelchair to the top of the steps and presses the downward button. The control system controls the bottom folding motor 2-5 at the bottom of the ground panel 2-3 and the motor of the guardrail 2-6 to work, so that the horizontal passage 2 is gradually opened until the movable fence 2-2 falls on the steps and the guardrail 2-6 forms a 90-degree angle. At the same time, after the two safety guardrails at the entrance and exit of the movable platform 1-2 are completely lowered, the motor in the linear power module 1-3 works to drive the movable platform 1-2 to slowly rise. When it rises to the height flush with the ground panel 2-3, the limit switch is triggered to stop. Subsequently, the alignment component 2-7 works to align and magnetically lock the movable platform 1-2 with the ground panel 2-3. Then the guardrail 2-6 is lifted, the safety guardrail at the exit of the movable platform 1-2 is lifted, and the safety guardrail at the entrance of the movable platform 1-2 remains lowered. After the user waits for the horizontal passage 2 to be completely opened and the guardrail 2-6 to be retracted, the user pushes the wheelchair into the horizontal passage 2, reaches the end of the horizontal passage 2 and enters the movable platform 1-2, and presses the downward button. The safety guardrail at the exit of the movable platform 1-2 is lowered, and the guardrail 2-6 is lowered. Then the linear power module 1-3 starts to descend, and the bellows 1-4 contracts until the movable platform 1-2 descends to the bottom and triggers the limit stop. The control system then controls the safety guardrail at the entrance of the movable platform 1-2 to open. The user pushes the wheelchair away from the movable platform 1-2. After a certain period of time, such as 60 seconds, the control system will lift the safety guardrail at the exit of the movable platform 1-2, the guardrail 2-6 of the horizontal passage 2, and fold the horizontal passage 2 to make the device enter the standby mode.
