Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hoistway elevators, in particular to a hoistway elevator based on a safety door. Background Art
[0002] Elevators are commonly used transportation mechanisms in buildings. Elevators can bring many conveniences to users, but the installation of elevators is a high-intensity, high-precision and relatively risky job.
[0003] However, most traditional platforms for installing elevators often have only a single door structure when in use. When a power outage or an unexpected situation occurs that the elevator cannot be opened from the inside, self-rescue is impossible, and there is no alarm measure, so there is a certain degree of danger in actual use; and it is also impossible to protect personnel when the door is closed, which is prone to safety hazards of pinching. For this reason, we propose a shaft elevator based on a safety door. Utility Model Content

[0014] (III) Beneficial effects
[0015] Compared with the prior art, the utility model provides a hoistway elevator based on a safety door, which has the following beneficial effects:
[0016] 1. The shaft elevator based on the safety door can send out a signal by pressing the power button, which is received by the receiver. When the receiver receives the signal, it is transmitted to the controller. The controller drives the two hydraulic telescopic rods and the buzzer alarm. The buzzer alarm sends out an alarm sound to quickly inform outsiders. When the two hydraulic telescopic rods are driven, the output ends thereof drive the two card blocks to move upward, so that the two card blocks move out of the two card slots and enter into the two installation slots respectively, thereby releasing the fixation of the life-saving door and the square slot, and the life-saving door can be rotated outwards through two hinges to open the square slot, so that users in the elevator body can also come out of the elevator body when the power is off and the operating state is closed, thereby preventing danger to the users.
[0017] 2. The shaft elevator based on the safety door can provide a buffer when the two door bodies are closed through the arrangement of the first spring and the circular block, through the expansion and contraction capacity of multiple first springs, to prevent the two protective pads from directly colliding and causing damage to the two door bodies. When the material of the protective pad is set to rubber material, it can provide protection when the two door bodies automatically close when the user enters the elevator body, to prevent the two door bodies from directly and rigidly contacting the user, thereby preventing the undesirable phenomenon of pinching.

When the material of the protective pad 6 is set to rubber material, it can provide protection when the user enters the elevator body 1 and the two door bodies 2 are automatically closed, preventing the two door bodies 2 from directly and rigidly contacting the user, thereby preventing the undesirable phenomenon of pinching. At the same time, when the elevator body 1 is in a state of power outage and unable to operate normally, the person trapped inside the elevator body 1 can send a signal by pressing the power button 15 and the signal is received by the receiver 17. When the receiver 17 receives the signal, it is transmitted to the controller 16. The controller 16 drives the two hydraulic telescopic rods 13 and the buzzer alarm 18. The buzzer alarm 18 emits an alarm sound to quickly inform outsiders. When driving the two hydraulic telescopic rods 13, the output end thereof drives the two card blocks 14 to move upward, so that the two card blocks 14 move out of the two card slots 10 and enter into the two installation slots 12 respectively, thereby releasing the fixation of the life-saving door 9 and the square slot 7, and the life-saving door 9 can be rotated outwardly through the two hinges 8 to open the square slot 7, so that the users in the elevator body 1 can also come out of the elevator body 1 when the power is off and the operating state is closed, thereby preventing danger to the users.
