Description

Technical Field

[0001] The present application relates to the technical field of elevator safety, and in particular to an elevator fault protection device. Background Art

[0002] With the development of economy and the growth of population, there are more and more high-rise buildings in modern cities, and elevators are becoming more and more popular in people's lives and work. While elevators bring people various conveniences, they also lurk with many hidden dangers. When an elevator breaks down, an elevator fault protection device needs to be used.

[0003] Existing elevator fault protection devices are often complicated to assemble and require a certain amount of time and labor to install, which increases the workload of the staff. Due to design limitations, the storage of these devices when not in use is also a problem. They often occupy a large space and are not easy to store and manage, which is particularly inconvenient for places with limited space. In addition, the devices are relatively fragile when facing changes in the external environment. For example, under the influence of natural wind, the devices may shift or even be blown by the wind to a position where they cannot function normally. In this case, even if the elevator fails, the protection device cannot effectively send out a warning signal, thereby failing to provide the necessary safety protection for passengers.

[0004] Therefore, in order to solve the above problems, the present application provides an elevator fault protection device.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0008] Preferably, the frame is movably connected to the protection box body through a limit block, and the frame cannot be completely separated from the protection box body when it is pulled outward, and a sliding block is fixedly installed on the top of the frame.

[0009] Preferably, the flip portion includes a rotating plate, a receiving groove and a receiving groove, wherein the rotating plate is flipped and arranged inside the frame through a rotating shaft, and an end of the rotating plate away from the pulling portion is provided with a receiving groove for receiving the fixing portion.

[0010] Preferably, the fixing portion comprises a piston rod and a suction head, wherein the suction head is movably clamped to the end of the accommodating groove through the piston rod.

[0011] Preferably, the top and bottom walls of the inner cavity of the protection box body are provided with slide rails for the slider to move, while the openings on the left and right sides of the inner cavity of the protection box body are only for the frame and the slider to pass through.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The elevator fault protection device uses a pulling part, a flipping part, and a fixing part in coordination. The frames are pulled out from the left and right ends of the protection box body until the limit block is engaged with the protection box body. Further, the rotating plates in the frames on both sides are flipped to 90 degrees, and the fixing parts at the ends of the rotating plates are pulled out, and the suction heads are adsorbed on the surrounding walls of the faulty elevator, forming an enclosed area. The device is convenient to store and easy to manage, and under the adsorption action of the suction heads, the protection device will not be displaced due to changes in the external environment.
