Embodiment Construction
[0031] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.
[0032] like figure 1 , figure 2 , image 3 , a deceleration safety elevator car, including a shaft, inside the shaft there is a car 1, the car 1 includes a car main body 11 and deceleration air cushions 12 attached and installed on both sides of the car main body 11;
[0033] The deceleration air cushion 12 includes an expansion pad 121 located on the inside and a friction pad 122 located on the outside. The expansion pad 121 is a hollow air pad, and the side is connected with the ventilation pipe 2, which has the action of inflation and expansion. The lower has the action of approaching or touching the side wall of the hoistway;
[0034] A one-way valve 3 is installed on the outside of the car 1, the one-way valve 3 includes an air inlet 31 and an air outlet 32, and the air outlet 32 is connected to the other end of the ventilation p...

Disclosed is a speed reduction safety elevator car. The speed reduction safety elevator car comprises a shaftway; the car exists in the shaftway and comprises a car body and speed reduction air cushions attached to the two sides of the car body; each speed reduction air cushion comprises an expansion cushion body located on the inner side and a friction cushion body located on the outer side, wherein the expansion cushion body is a hollow air cushion body, the side of the expansion cushion body is connected with a ventilation pipe, the expansion cushion body has the action of air-inflation expansion, and the friction cushion body has the action of approaching or making contact with the side wall of the shaftway under the action of air-inflation expansion of the expansion cushion body; a one-way valve is mounted on the lower portion of the exterior of the car and comprises an air inlet and air outlets, and the air outlets are connected with the other ends of the ventilation pipes; an air collecting device is mounted below the one-way valve and comprises an air collecting umbrella and an air collecting umbrella sleeve; and the air collecting umbrella comprises an opening portion anda ventilation connecting portion, the upper end of the opening portion communicates with the lower end of the ventilation connecting portion, and the upper end of the ventilation connecting portion isconnected with the air inlet of the one-way valve.
Description
technical field [0001] The invention relates to the field of traction elevators, in particular to a deceleration safety elevator car. Background technique [0002] In the existing safety protection measures for elevators, when the speed of the car exceeds 1.3 times the rated speed, the electric actuation is forced to cut off the power supply, so that the brake on the traction main machine clamps the main shaft of the traction machine; when the speed of the car exceeds When the rated speed is 1.4 times the mechanical action, the safety gear on the car is activated, and the brake block is used to clamp the rail; when the car falls to the pit, the buffer on the pit provides the reaction force of the car to avoid The accident that the car crashed occurred. Among them, the safety gear is the most important safety device to prevent the elevator from falling, but the work of the safety gear requires the cooperation of the speed limiter, which has certain potential safety hazards; ...
