Description
Technical Field
The utility model relates to a fire control safety technical field, especially a step door structure based on platform of fleing.
Background
High-rise buildings are high in floors, many people inside the buildings are in the buildings, when accidents happen, people need to be evacuated as soon as possible, the speed is slow, confusion is easy to occur, smoke generated by fire is toxic gas, people are easy to fumigate, the corridor is the place with the most smoke and cannot be used, an elevator can be closed, people can only wait for rescue, and the high-rise buildings are very passive and do not have devices capable of escaping from the high-rise buildings quickly and safely.
Therefore, the device which can be installed indoors and can be operated by people to safely escape from a high-rise building is designed, a frame capable of hiding escape steps is required to be used when the device is used, a door capable of being opened towards the outside of the frame is required to be arranged on the frame, the step door is closed to hide the steps when the device is not used, and an opening capable of expanding the telescopic steps is formed when the device is used.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model provides a step door structure based on platform of fleing, realization high-rise personnel that can be fine are under emergency's escape route build, and can avoid damaging the step with the fine hiding of step when not using.
The technical scheme of its solution problem is, a step door structure based on platform of fleing, including setting up the guard gate at platform step portion of fleing, the guard gate is outwards open formula structure, actuating system is connected to the guard gate, actuating system includes the motor, the motor is through electromagnetic clutch connection output shaft, the output shaft is connected with the pivot through the chain, it has the driving lever to stretch out in the pivot, the L type pole that the driving lever is located on the guard gate through the connecting rod connection, the driving lever is articulated with the connecting rod ball, the connecting rod is articulated with L type pole ball, opening and closing of motor control guard gate.
The utility model discloses think about novelty, the structure is ingenious, the realization high-rise personnel that can be fine are in putting up of emergency escape way under emergency, easy operation simultaneously, compact structure.

Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
As can be seen from fig. 1-5, a step door structure based on platform of fleing, including setting up guard gate 1 at platform step portion of fleing, guard gate 1 is the outward opening formula structure, guard gate 1 connects actuating system, actuating system includes motor 2, motor 2 connects output shaft 4 through electromagnetic clutch 3, output shaft 4 is connected with pivot 6 through chain 5, it has driving lever 7 to stretch out on the pivot 6, driving lever 7 is connected L type pole 9 that is located on guard gate 1 through connecting rod 8, driving lever 7 and connecting rod 8 ball joint, connecting rod 8 and L type pole 9 ball joint, opening and closing of motor 2 control guard gate 1.
Still include manual drive device, manual drive device includes the drive shaft 10 of being connected with output shaft 4, and detachable is connected with crank 11 on the drive shaft 10, and when the circular telegram, motor 2 and output shaft 4 intercommunication, motor 2 drive output shaft 4 and rotate, and when the outage, motor 2 and output shaft 4 disconnection are through rotating crank 11 and drive output shaft 4 and rotate.
When the utility model is used, the utility model,
under the condition that this device is not used in normal conditions, guard gate 1 is in the closed condition, and the inside step of fleing of guard gate 1 protects the safety of step.
When the emergency condition needs to use the escape platform, the driving system is started, the motor 2 rotates to drive the output shaft 4 to rotate, the output shaft 4 drives the rotating shaft 6 to rotate, the shifting rod 7 pushes the connecting rod 8 to open the protective door 1, and after the protective door 1 is completely opened, the folding step of the escape platform can be unfolded, so that high-rise personnel can escape.
In this device, guard gate 1 adopts to open structure, and open structure can reduce the space that guard gate 1 took when opening, and easier operation when opening guard gate 1.
The device also comprises a manual driving system, under the condition of insufficient power supply, the crank 11 is connected in the driving shaft 10, and the crank 11 is rotated to drive the output shaft 4 to rotate, so that the protective door 1 is smoothly opened, and the escape platform is successfully built under the condition of insufficient power.
The utility model discloses following beneficial effect has: the protective door 1 can be opened from the outside, so that the steps can be smoothly opened in an emergency; when the power supply is insufficient, the protective door 1 can be driven to open through the manual driving system, and the building of the escape platform is not influenced under any condition.
