When the stair space needs to be used, the flip staircase structure is reset to its initial position, and the stairwell can now be used as a normal staircase. The present invention enables the space in the stairwell to be equipped with the function of installing an elevator without affecting the stairway's function, thereby greatly improving space utilization.

[0035] The transverse support beams include a first transverse connecting beam 103, a second transverse connecting beam 104 and a third transverse connecting beam 105. A hall door assembly 400 is provided on the corresponding step platform on each floor. The first transverse connecting beam 103 and the second transverse connecting beam 104 are supporting connecting members arranged on the upper and lower sides of the hall door assembly 400, and the two ends of the first transverse connecting beam 103 and the second transverse connecting beam 104 are respectively fixedly connected to the vertical support beams 102 on both sides. There are four vertical support beams 102, which are respectively arranged in pairs on both sides of the steps on the same side of the two flights of stairs. The third transverse connecting beam 105 is arranged on the two vertical support beam brackets 102 on the same side to increase the connection strength. The top of the four vertical support beams 102 is installed with a top mounting bracket 107, and the elevator structure can be installed between the four vertical support beams 102. A bracket 109 is provided on one side of the hoistway frame, which can simultaneously install the elevator car guide rail 108 and the counterweight guide rail, and a guide rail bracket 110 is also provided between the vertical support beam 102 and the elevator car guide rail 108.

[0036] The transmission connection assembly 302 includes a first rotating shaft 303 provided on the fixed staircase structure 201, a plurality of rotating members 304, and a second rotating shaft 305 provided on the tilting staircase structure 202. The output shaft of the control motor 301 is fixedly connected to the first rotating shaft 303, and the rotating member 304 is disposed between the first rotating shaft 303 and the second rotating shaft 305. The control motor 301 is fixedly mounted on the side wall of the fixed staircase structure 201.

[0037] When the control motor 301 is started, the control motor 301 can drive the rotating shaft 1 303 to rotate. The rotation of the rotating shaft 1 303 drives the two rotating parts 304 to rotate. The rotation of the rotating parts 304 drives the rotating shaft 2 305 to rotate. The rotation of the rotating shaft 2 305 drives the connected flip staircase structure 202 to rotate based on the fixed staircase structure 201.

[0038] After the elevator is installed, it serves as the only means of going up and down;

[0039] A. When the fire-fighting function is activated (the elevator cannot run and the stairs are the only means of going up and down), press the fire button, and the elevator car automatically runs to the confirmed position. The reversible staircase structure 202 of the stairs on each floor is reversed. When the reversible staircase structure 202 touches each in-place switch, the elevator door lock in the hall door assembly is always closed, and the elevator door is in a state that can be manually pushed outward. At the same time, the elevator door can be kept closed by the door closer, so that the stairs can be passed up and down.

[0040] B. When the elevator is out of power, the elevator battery will be started to provide power.

[0041] C. When the elevator stops due to a malfunction and cannot be restored to normal operation in a short time, you can activate the manual release brake on the first floor to allow the elevator to rise to the top floor using the gravity difference between the car and the counterweight, so as to make room for the stairs to be flipped.

[0042] Specific implementation method:

[0043] The hoistway structure 100 of the present invention can realize the mutual switching between the stairway passage space and the hoistway space for elevator operation through the stairway structure 200 with a partially reversible staircase on the same side. When the elevator in the hoistway space needs to be used, it is necessary to start the hoistway switching mechanism 300, and first synchronously start a plurality of control motors 301. The control motors 301 can drive the rotation shaft 1 303 to rotate. The rotation of the rotation shaft 1 303 drives the two rotating parts 304 to rotate. The rotation of the rotating parts 304 drives the rotation of the rotation shaft 2 305. The rotation of the rotation shaft 2 305 drives the connected reversible stairway structure 202 to rotate based on the fixed stairway structure 201, so that a vertically connected channel is formed on the stairway structure 200. The reversible stairway structure 202 can serve as the rear side protective baffle of the hoistway structure 100, so that the hoistway can realize the elevator carrying passengers for up and down passage. When the staircase space is needed, the staircase structure 202 is flipped and reset to its initial position. At this time, the stairwell can be used for normal staircase passage. The present invention enables the space in the stairwell to be equipped with an elevator without affecting the staircase passage function, thereby greatly improving space utilization.

[0044] Specific embodiment 2:

When it is necessary to drive the flip stair structure 202 of the upper elevator to flip, the linear motor 307 is started first. The rotation of the linear motor 307 can drive the telescopic rod 309 in the telescopic sleeve 308 to extend or retract in a straight line, thereby driving the flip stair structure 202 to flip based on the rotating shaft 303 on the fixed stair structure 201; the stair structure of the lower stair, one end of the fixed stair structure 201 is fixedly connected to the rest platform 106, and the other end of the fixed stair structure 201 is rotatably connected to the flip stair structure 202. The stair structure 201 of the lower stair can be flipped by using the control motor drive transmission connection assembly 302 in Example 1. At the same time, it can also be replaced with the transmission structure driven by the linear motor 307 of the upper stair, for flip control of the flip stair structure 202 in the stair structure. The staircase is composed of a continuous staircase, a rest platform 106 (rest platform) and enclosure components. The staircase structure adopts the modification of the staircase to enable normal stair walking and flip it to vertically form a partial shaft rear wall baffle for safety protection.

[0046] Specific embodiment 3:

A third drive motor 204 is fixed to the resting platform 106, and the rectangular flip plate 203 is fixed to the output shaft of the third drive motor 204. This staircase structure utilizes a modified platform section to enable normal resting and flipping to a vertical position, forming a partial shaft rear wall baffle for safety protection.

[0048] Specific embodiment 4:

[0049] Referring to Figures 1, 3, 5, 6 and 7, this embodiment adds a partition flipping mechanism 500 on the basis of specific embodiment 1. The partition flipping mechanism 500 is arranged at the lower side of the fixed stair structure, and includes a motor fixing seat 501, a driving motor 502 arranged on the motor fixing seat 501, and a flipping plate 503 arranged on the driving motor 502. When the flipping plate 503 is not in use, it is in a state of being arranged parallel to the lower surface of the step section. The driving motor 502 is fixedly installed on the side of the fixed stair structure 201 close to the side of the flip stair structure 202. A driving shaft 504 is fixedly provided on the output shaft of the driving motor 502. The driving shaft 504 is fixedly connected to the flip plate 503. When the stair space needs to be switched to the shaft space for installing the elevator, the driving motor 502 is started, and the driving motor 502 rotates to drive the driving shaft 504 to rotate. The driving shaft 504 rotates to drive the flip plate 503 to rotate, which can cooperate with the flip stair structure 201 on the lower side to form a rear baffle of the shaft frame 101 in the corresponding floor for safety protection.

[0050] Specific embodiment 5:

[0051] Referring to Figures 1 to 6 , the hoistway frame 101 also includes a first transverse connecting beam 103, a second transverse connecting beam 104, and a third transverse connecting beam 105. The vertical support beams 102 on the same side are fixedly connected by several sets of first transverse connecting beams 103. Second and third transverse connecting beams 104, 105 are installed between two vertical support beams 202 on the same floor facing the rest platform 106. These second and third transverse connecting beams 104, 105 serve as support members for the upper and lower portions of the hallway door assembly 400, respectively. The hallway door assembly 400 includes a door frame 401, two sets of hallway doors 402 disposed within the door frame 401, and a door closer 403 disposed between the door frame 401 and the hallway doors 402. The door closer 403 on the hallway door 402 automatically closes the door when the door is opened, released by the compression of a hydraulic actuator. The hydraulic actuator, similar to a spring-loaded door, ensures that the door accurately and promptly closes to its initial position after opening.

[0052] Specific embodiment 6:

[0053] Referring to Figures 1 to 6 , a first reversible tread mechanism 600 is provided at the other end of the reversible staircase structure 202, away from the fixed staircase structure 201.

Limiting grooves 604 are provided on both side walls of the reversible staircase treads 202. These limiting grooves 604 limit the rotation angle of the tread connectors, thereby controlling the position of the reversible staircase treads 202. The first reversible tread mechanism 600 is installed only on the final step of the reversible staircase structure 202, which is located on the descending staircase.

[0054] When the elevator in the shaft space needs to be used, the shaft switching mechanism 300 needs to be started. First, several control motors 301 are started synchronously. The control motor 301 can drive the rotating shaft 1 303 to rotate. The rotation of the rotating shaft 1 303 drives the two rotating members 304 to rotate. The rotation of the rotating member 304 drives the rotating shaft 2 305 to rotate. The rotation of the rotating shaft 2 305 drives the connected flip stair structure 202 to rotate based on the fixed stair structure 201, so that a vertically connected channel is formed on the stair structure 200. The flip stair structure 202 can serve as a rear protective baffle of the shaft structure 100. When the flip stair structure 202 rotates, the first flip pedal mechanism 600 is started, that is, the driving motor 2 601 is started. The driving motor 2 601 drives the two pedal connecting members 603 to rotate. One of them contacts the upper side wall of the limiting groove 604. The pedal connecting member 603 rotates and drives the first flip pedal 602 to rotate to the upper limit position, so that the first flip pedal 602 flips a little angle to avoid protective interference of the flip stair structure 202.

[0055] When the stair space needs to be used, the flip stair structure 202 is reset to the initial position. At this time, the first flip pedal mechanism 600 is started, that is, the drive motor 2 601 is started. The drive motor 2 601 drives the two pedal connectors 603 to rotate so that one of them contacts the lower side wall of the limit groove 604. The pedal connector 603 rotates and drives the first flip pedal 602 to rotate to the lower limit position, so that the first flip pedal 602 serves as a connecting pedal between the floor platform 107 and the flip stair structure 202 in the stair structure 200, and the stairwell can be used for normal stair walking.
