Embodiment Construction

[0019] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and structural, method, or functional changes made by those skilled in the art according to these embodiments are all included in the protection scope of the present invention.

[0020] An elevator fire protection system is an elevator that can be used for a longer time in a fire, for example, the electronic components of the elevator can be waterproof, the elevator car is fireproof, or has a special fireproof working mode.

[0021] figure 1 Shown is an elevator fire protection system in accordance with an embodiment of the present invention. An elevator car 1 and a counterweight 2 are provided in the elevator shaft 10 . Both the elevator car 1 and the counterweight 2 are driven by a support device 3 . The elevator car 1 and the counterweight 2 can be moved vertically in t...

Abstract

In the elevator fire protection system of the present invention, the elevator car arranged in the elevator shaft is supported by a supporting device; a car roller is installed on the bottom of the elevator car to drive the supporting device to make the elevator car go up or down; The elevator shaft wall of the elevator shaft is provided with an opening on the second floor, and the opening is closed by the second elevator shaft door. After closing, there is a gap between the second elevator shaft door and the floor of the second floor; On the second floor, the fire extinguishing device sprays fire extinguishing water and gathers on the floor of the second floor and flows into the top of the elevator car from the gap into the elevator shaft, and finally gathers at the bottom of the elevator shaft; a protective member is provided on the top edge of the elevator car, and the protection The components surround the periphery of the supporting device, a cross bar is arranged on the top of the elevator car, the protective member is lower than the cross bar, and the fire extinguishing device is also provided with a flow control device. Use protective components to prevent the support device from being sprayed by fire extinguishing water.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator fire fighting system. Background technique [0002] Modern elevator installations or attached elevator fire protection systems for this purpose must operate reliably. This means that the mechanical parts of elevator installations need to be kept dry. It must be ensured that the support is still driven by the pulley as planned. The extinguishing water in this case affects the traction of the support device on the drive pulley. On the one hand, the fire extinguishing water will directly reduce the friction coefficient between the drive pulley and the support device, and on the other hand, the presence of lubricants in the fire extinguishing water will also affect the traction between the support device and the pulley. Wetted support means with extinguishing water can thus lead to a reduction in traction or even a complete loss of traction. Therefore, measures need...
