Embodiment Construction

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

[0020] The elevator fire protection system is an elevator that can be used for a longer period of 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 according to an embodiment of the present invention. An elevator car 1 and a counterweight 2 are arranged in the elevator shaft 10 . Both the elevator car 1 and the counterweight 2 are driven by a supporting device 3 . The elevator car 1 and the counterweight 2 can be moved vertically...

Abstract

The invention discloses an elevator fire fighting system. An elevator car arranged in an elevator shaft is supported by a support device; a car roller is mounted at the bottom of the elevator car, and drives the support device to ascend or descend the elevator car; an elevator shaft wall of the elevator shaft is provided with an opening in a reverse second floor; the opening is closed by a reverse second elevator shaft door; a gap is formed between the closed reverse second elevator shaft door and a reverse second floor baseplate; a fire extinguishing device is mounted on the reverse second floor, and sprays fire extinguishing water to gather on the reverse second floor baseplate and flows to the top of the elevator car in the elevator shaft from the gap so as to finally gather at the bottom of the elevator shaft; a protective component is arranged at the top edge of the elevator car, and surrounds the outer periphery of the support device; a cross bar is arranged at the top of the elevator car; and the protective component is butted against the cross bar. The protective component is adopted to prevent the fire extinguishing water from being sprayed on the support device.

Description

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