[0026] In this embodiment, please refer to the appendix. Figure 1 and 3 When the side-folding protective work platform is in operation, the rotary support or reset mechanism is activated by the programmable controller 7. The rotary support or reset mechanism rotates to present a support state. The flipping and folding mechanism is activated by the programmable controller 7. The flipping and folding mechanism drives the movable platform 3 to flip and extend onto the rotary support or reset mechanism, presenting a horizontal plane with the fixed mounting frame 1, forming a work platform.

At this time, the operator can stand on the movable platform 3 in the area inside the two scissor telescopic guardrails 6 and the fixed guardrail 4 to carry out the work.

[0027] When the transport vehicle is in operation, the workers leave the platform area, the telescopic drive mechanism is activated to reset the fixed guardrail 4, the two movable frames 5 and the two scissor telescopic guardrails 6, the flipping and folding mechanism is activated to reset the movable platform 3, and the rotating support or reset mechanism is activated to reset, so as to achieve the folding of the side movable platform 3 and avoid affecting the transport vehicle.

[0028] Specifically, the installation mechanism includes a mounting frame 101 fixed to the bottom of the fixed mounting frame 1, and the mounting frame 101 is fixed to the side wall of the passageway working space by bolts.

[0029] In this embodiment, please refer to the appendix. Figure 1 The fixed mounting bracket 1 is fixed to the side wall of the passageway by bolts, thereby achieving the fixed installation of the fixed mounting bracket 1.

[0030] Specifically, the rotation support or reset mechanism includes a motor 202 fixed to the top of the fixed mounting frame 1 and two drive shafts 203 symmetrically arranged at the bottom of the fixed mounting frame 1. The top of the fixed mounting frame 1 is covered by a protective shell 201 around the motor 202. The top of one drive shaft 203 is connected to the output end of the motor 202 via a coupling, and the top of the other drive shaft 203 is connected to the inner wall of the fixed mounting frame 1 via a bearing. A support arm 205 and a gear 204 are fixedly sleeved on the drive shaft 203 from top to bottom. The two gears 204 are meshed and connected.

[0031] In this embodiment, please refer to the appendix. Figure 1 and 2 The support of the rotary support or reset mechanism is controlled by the programmable controller 7 to start the motor 202. The motor 202 drives the output end to rotate, and the output end of the motor 202 drives the connected drive shaft 203 to rotate clockwise. The connected drive shaft 203 drives the connected support arm 205 and gear 204 to rotate in the same direction. The connected gear 204 drives the meshing gear 204 to rotate counterclockwise. The meshing gear 204 drives the connected drive shaft 203 to rotate in the same direction. The connected drive shaft 203 drives the connected support arm 205 to rotate in the same direction, so as to realize the movement and support of the two support arms 205 towards the movable platform 3.

[0032] The reset of the rotary support or reset mechanism is achieved by the reverse rotation of motor 202.

[0033] Specifically, the telescopic drive mechanism includes a first electric cylinder 301 fixedly connected to the side wall of the fixed frame 2 near the passageway working space. The output end of the first electric cylinder 301 is fixedly connected to the movable frame 5, and the first electric cylinder 301 is electrically connected to the programmable controller 7.

[0034] In this embodiment, please refer to the appendix. Figure 1 and 3 The telescopic drive mechanism is controlled by the programmable controller 7 to start the first electric cylinder 301. The first electric cylinder 301 drives the output end to extend and retract, and the output end of the first electric cylinder 301 drives the movable frame 5 to extend and retract, so as to realize the telescopic drive of the movable frame 5.

[0035] Specifically, the flipping and folding mechanism includes a connecting shaft 404 rotatably connected between the fixed mounting frame 1 and the movable platform 3 near each other's side walls, two first mounting seats 401 symmetrically fixed to the top of the fixed mounting frame 1 on the outside of the two fixed frames 2, and two second mounting seats 403 fixed to the top of the movable platform 3 at the same position.

[0036] In this embodiment, please refer to the appendix. Figure 1 and 2The flipping and folding mechanism is controlled by the programmable controller 7 to start the second electric cylinder 402. The second electric cylinder 402 drives the output end to extend and retract. The output end of the second electric cylinder 402 drives the second mounting base 403 to move. During the movement of the second mounting base 403, the movable platform 3 is driven to flip and extend or retract and fold along the connecting shaft 404.

[0037] Example 2

[0038] The difference between this embodiment and Embodiment 1 is that:

[0039] Specifically, the fixed frame 2 and the movable platform 3 are equipped with a warning mechanism, which includes a processor 504 fixed to the fixed frame 2 and located below the programmable controller 7, and a laser rangefinder 503, two voice warning devices 502 and three warning lights 501 symmetrically fixed to the two side walls of the movable platform 3 and arranged in sequence. The two voice warning devices 502 on the same side have different warning voices, and the three warning lights 501 on the same side have different warning colors. The laser rangefinder 503 is electrically connected to the processor 504, the processor 504 is electrically connected to the programmable controller 7, and the programmable controller 7 is electrically connected to the voice warning devices 502 and the warning lights 501.

[0040] In this embodiment, please refer to the appendix. Figure 1 and 3 The laser rangefinders 503 on both sides continuously measure whether there are transport vehicles in the roadway. If a transport vehicle is detected in the roadway and is within a set first distance range (relatively far), the processor 504 transmits a signal to the programmable controller 7. The programmable controller 7 controls the outermost warning light 501 on the side with the transport vehicle to light up, reminding the transport vehicle to stop and wait. If the transport vehicle does not stop and wait, and is within a set second distance range (relatively close), the processor 504 transmits a signal to the programmable controller 7, and the programmable controller 7 controls the middle warning light on the side with the transport vehicle. When the side warning light 501 illuminates and the side voice warning device 502 issues a voice warning, the transport vehicle is given a dual reminder via both light and voice, indicating that it must stop and wait. At this time, the operators should prepare to evacuate. If the transport vehicle does not stop and wait, and the transport vehicle is within the set third distance range (near), the processor 504 transmits a signal to the programmable controller 7. The programmable controller 7 controls the other side warning light 501 on the side of the transport vehicle to illuminate and the other side voice warning device 502 to issue a serious voice warning, giving the transport vehicle a dual reminder via both light and voice, indicating that it must stop and wait. At this time, the operators should evacuate, and the platform will fold.

[0041] The working principle of this utility model:

[0042] Two mounting brackets 101 are fixed to the side wall of the passageway working space by bolts to complete the fixed installation of the mounting bracket 1 and the side wall of the passageway working space.

[0043] During platform extension operations, the programmable controller 7 controls the motor 202 to start, driving the output end of the motor 202 to rotate. The output end of the motor 202 drives the connected drive shaft 203 to rotate clockwise, which in turn drives the connected support arm 205 and gear 204 to rotate in the same direction. The connected gear 204 drives the meshing gear 204 to rotate counterclockwise, which in turn drives the connected drive shaft 203 to rotate in the same direction. The connected drive shaft 203 drives the connected support arm 205 to rotate in the same direction. At this time, the two support arms 205 rotate towards the movable platform 3 until the set time is reached and they stop. At this point, the two support arms 205 can provide support. The programmable controller 7 controls the two second electric cylinders 402 to start, driving the output end of the two second electric cylinders 402 to extend. The output of the two electric cylinders 402 drives the two second mounting seats 403 to move. During the movement of the two second mounting seats 403, the movable platform 3 is rotated along the connecting shaft 404 until the set time is reached and it stops. At this time, the movable platform 3 and the fixed mounting frame 1 are on the same horizontal plane, forming a working platform. The programmable controller 7 controls the two first electric cylinders 301 to start. The output of the two first electric cylinders 301 is extended. The output of the two first electric cylinders 301 drives the two movable frames 5 to extend. During the extension of the two movable frames 5, the fixed guardrail 4 is moved and the two scissor-type telescopic guardrails 6 are extended until the set driving time is reached and it stops. At this time, the two scissor-type telescopic guardrails 6 and the fixed guardrail 4 form a guardrail. The operator can stand on the movable platform 3 in the area inside the two scissor-type telescopic guardrails 6 and the fixed guardrail 4 to carry out the work.

[0044] During platform operation, the laser rangefinders 503 on both sides continuously measure whether there are transport vehicles in the driveway. If a transport vehicle is detected in the driveway and is within a set first distance range (relatively far), the processor 504 transmits a signal to the programmable controller 7. The programmable controller 7 then controls the outermost warning light 501 on the side with the transport vehicle to illuminate, providing a visual reminder that the transport vehicle must stop and wait. If the transport vehicle does not stop and wait, and is within a set second distance range (relatively close), the processor 504 transmits a signal to the programmable controller 7, which then controls the middle warning light 501 on the side with the transport vehicle. Warning light 501 illuminates and the sidemost voice warning device 502 issues a voice warning, providing a dual reminder to the transport vehicle via both light and voice, indicating that it needs to stop and wait. At this time, the operators should prepare to evacuate. If the transport vehicle does not stop and wait, and the transport vehicle is within the set third distance range (close), the processor 504 transmits a signal to the programmable controller 7. The programmable controller 7 controls the other sidemost warning light 501 on the side of the transport vehicle to illuminate and the other sidemost voice warning device 502 to issue a serious voice warning, providing a dual reminder to the transport vehicle via both light and voice, indicating that it needs to stop and wait. At this time, the operators should evacuate, and the platform will fold.

[0045] The platform folds, meaning the aforementioned structure is reset, to avoid affecting the transport of vehicles.

[0046] The programmable controller 7, motor 202, first electric cylinder 301, second electric cylinder 402, warning light 501, voice warning device 502, laser rangefinder 503, and processor 504 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
