Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator safety equipment technology, specifically an elevator overload device. Background Technology
[0002] With the acceleration of urbanization, elevators, as an indispensable vertical transportation tool in high-rise buildings, have attracted much attention regarding their safety performance. Elevator overload is one of the major causes of elevator safety accidents. Existing elevator overload devices and overload switches are easily damaged or displaced, leading to inaccurate overload signals. Utility Model Content
[0003] This utility model provides an elevator overload device to solve the problems mentioned in the background art.
[0004] To solve the above-mentioned technical problems, the solution of this utility model is as follows:
[0005] An elevator overload device includes: an elevator car, a car vibration damping device, a car frame, an overload switch bracket, and an overload switch. The elevator car is connected to the car vibration damping device, the car vibration damping device is connected to the car frame, the car frame is connected to the overload switch bracket, and the overload switch bracket is connected to the overload switch. The overload switch bracket is provided with a maximum limit point, and the overload switch is provided with a minimum travel limit point.
[0006] Preferably, the highest limit point of the bracket on the overload switch bracket is higher than the lowest limit point of the travel on the overload switch.
[0007] Preferably, the overload switch bracket is fixedly connected to the car frame by two screws.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0009] 1. The top of the overload switch bracket is higher than the compression stroke of the overload switch, effectively protecting the switch from being damaged by impact;
[0010] 2. The overload switch bracket is installed with two screws, which is relatively secure and the overload signal is more accurate. Attached Figure Description

[0014] Figure 4This is a schematic diagram of the installation of the overload switch of this utility model. Detailed Implementation
[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0016] Reference Figure 1-4 The elevator overload device of this utility model includes: an elevator car 1, a car vibration damping device 2, a car frame 3, an overload switch bracket 4, and an overload switch 5. The elevator car 1 is connected to the car vibration damping device 2, the car vibration damping device 2 is connected to the car frame 3, the car frame 3 is connected to the overload switch bracket 4, and the overload switch bracket 4 is connected to the overload switch 5. The overload switch bracket 4 is provided with a maximum limit point 6, and the overload switch 5 is provided with a minimum travel limit point 7.
[0017] Specifically, the highest limit point 6 of the bracket on the overload switch bracket 4 is higher than the lowest limit point 7 of the travel on the overload switch 5. This effectively protects the switch from being damaged.
[0018] Furthermore, the overload switch bracket 4 is fixedly connected to the car frame 3 with two screws. Using two screws for installation provides a more secure connection and more accurate overload signal.
[0019] The working principle of this utility model is as follows:
[0020] The overload switch bracket 4 and overload switch 5 are fixed to the car frame 3 with two screws. As the weight of the elevator car 1 changes, the compression of the car shock absorption device 2 changes accordingly. When the elevator is overloaded, the overload switch 5 is activated, and the car 1 continues to be loaded. Because the highest limit point 6 of the bracket set on the overload switch bracket 4 is higher than the lowest limit point 7 of the overload switch 5, the switch is effectively protected from damage. The two screws make the device more secure and the overload signal more accurate.
[0021] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
