Description

Technical Field

[0001] The invention belongs to the technical field of ground filling tools, in particular to a hand-cranked self-rescue screw elevator car. Background Art

[0002] If a home elevator has a fault that the elevator system cannot repair itself, the home elevator must be equipped with a rescue system in the car. There must be a device in the elevator car that allows passengers to manually drive the elevator to achieve self-rescue. Because home elevators are private products for special use, unlike public products, once a passenger is trapped in the car, it is not easy to be found. The installation place is in a private residence. If a person is trapped in the elevator car at home, even if he can call for help, waiting for rescuers to arrive will affect the rescue because the rescuers cannot enter the door to rescue. If a self-rescue device is installed in the car, the passengers trapped in the car can implement self-rescue.

[0003] The hand-cranked self-rescue screw elevator car in the prior art mainly includes an elevator car body, a mounting plate, a mounting frame, a reduction gear box, a drive motor, a cylindrical body, an external gear, an external screw, a self-rescue window, a self-rescue operating lever, a transmission rod, a drive gear and a threaded barrel. When in use, the drive gear is meshed with the external gear. At this time, the self-rescue operating lever is rotated or the drive motor is started, so that the reduction gear box can drive the transmission rod to rotate, and then the drive gear and the external gear can be driven to rotate, and then the threaded barrel can be driven to move along the external screw, so that the elevator moves up and down.

[0004] However, during use, when the faulty elevator car is moved to the level floor, the elevator door needs to be opened manually. If the power is not completely cut off when opening the elevator door, it is very easy to be pinched by the automatically opened elevator door at the moment of opening the elevator door, resulting in injury. Summary of the invention

At this time, the driving gear 15 is meshed with the external gear 10. At this time, the self-rescue operating rod 13 is rotated or the driving motor 5 is started, so that the reduction gear box 4 can drive the transmission rod 14 to rotate, and then the driving gear 15 and the external gear 10 can be driven to rotate, and then the threaded cylinder 16 can be driven to move along the external screw 11, so that the elevator moves up and down;

[0043] S3. At this time, separate the threaded clamping rod 712 from the threaded clamping hole 711, and separate the first clamping rod 718 from the first clamping hole 717, rotate the L-shaped plate 719 to fix it with the rectangular auxiliary block 720, and then fix it. At this time, push the operating handle 713 so that the operating handle 713 can drive the stretching door 78 to move, and then drive the second dovetail sliding block 76 to slide in the second rectangular groove 75, and then open the stretching door 78.
