[0026] In order to enable those skilled in the art of this technology to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.

[0027] As recorded in the background art, traditional steel strip breakage detection schemes usually rely on installing complex sensors or detection devices at both ends of the steel strip, and judge whether a breakage occurs by monitoring parameters such as the tension and vibration of the steel strip. The advantage of this method is that it can monitor the running state of the steel strip in real time and accurately, but there are also significant limitations at the same time; firstly, these detection devices are often costly. High-precision sensors and complex signal processing systems not only increase the procurement cost of the equipment, but also bring higher maintenance costs. For elevator manufacturers and operators, this undoubtedly increases the economic burden; secondly, traditional detection devices occupy a large amount of hoistway space.

[0028] To solve this technical problem, this utility model provides a steel strip breakage detection device.

[0029] Specifically, please refer to Figures 1 - 3 , the steel strip breakage detection device specifically includes:

[0030] Breakage top plate 104, screw 103, fixed end plate 106, linking rod 107, switch hitting plate 108 and safety switch 110;

[0031] Among them, the breakage top plate 104 is used to press on the end of the elevator rope head assembly and is arranged on the elevator crossbeam through the screw 103 and the fixed end plate 106; one end of the breakage top plate 104 is fixed with a linking rod 107, a switch hitting plate 108 is arranged on the linking rod 107, and a safety switch 110 is arranged on one side of the switch hitting plate 108.

[0032] The steel belt breakage detection device provided by the present utility model, through the design of this application, enables the application to respond quickly when the elevator steel belt breaks. By means of the linkage rod 107 and the switch striking plate 108, the safety switch 110 is triggered, and the elevator is stopped in time. This rapid response mechanism effectively prevents safety accidents caused by belt breakage and ensures the safety of passengers and elevator equipment. Compared with the prior art, through optimized design, the number of components and complexity are reduced, the manufacturing and installation costs are significantly reduced, the device structure is designed compactly, the occupied space is reduced, which helps to optimize the layout of the elevator hoistway and improve the space utilization rate.

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0036] Example 1, please refer to Figures 1 - 3 , a steel belt breakage detection device, including a breakage top plate 104, a screw 103, a fixed end plate 106, a linkage rod 107, a switch striking plate 108 and a safety switch 110;

[0037] Among them, the breakage top plate 104 is used to press on the end of the elevator rope head assembly and is arranged on the elevator crossbeam through the screw 103 and the fixed end plate 106; a linkage rod 107 is fixed at one end of the breakage top plate 104, a switch striking plate 108 is arranged on the linkage rod 107, and a safety switch 110 is arranged on one side of the switch striking plate 108; when the elevator steel belt breaks, the breakage top plate 104 is pushed by the spring of the rope head assembly to pull the switch striking plate 108 through the linkage rod 107 to trigger the safety switch 110 and stop the elevator in time. This rapid response mechanism effectively prevents safety accidents caused by belt breakage and ensures the safety of passengers and elevator equipment. Compared with the prior art, through optimized design, the number of components and complexity are reduced, the manufacturing and installation costs are significantly reduced, the device structure is designed compactly, the occupied space is reduced, which helps to optimize the layout of the elevator hoistway and improve the space utilization rate.

[0038] For easy understanding, this application uses to represent the rope head assembly, B represents the elevator crossbeam, and is marked in the figure.

[0039] Further, as Figure 3As shown in the figure, tapping holes are provided on the fixed end plate 106, and one end of the screw rod 103 is connected to the tapping holes. The number of screw rods 103 is two, and the two screw rods 103 are respectively arranged on both sides of the broken belt top plate 104. The outer surface of the screw rod 103 is inserted and connected to the broken belt top plate 104 to play a role in fixing and guiding the broken belt top plate 104, ensuring that the broken belt top plate 104 always moves in a straight line during the movement without deviation or jamming. This is crucial for ensuring the precise operation of the device when a belt break occurs. Because if the movement of the broken belt top plate 104 deviates, it may cause the switch hitting plate 108 to fail to accurately trigger the safety switch 110, thus affecting the safety protection function of the entire device. At the same time, the uniform fixing force can disperse stress, extend the service life of the device, and reduce component damage caused by excessive local stress.

[0040] Further, as Figure 2 shown, a third round hole 5 for the screw rod 103 to pass through is provided on the elevator crossbeam, and a fourth round hole 2 is also provided on the elevator crossbeam. The fourth round hole 2 is used to prevent the spring of the rope socket assembly from hitting the fixed end plate 106 when it contracts. This not only extends the service life of the fixed end plate 106 but also reduces device failures and maintenance costs caused by damage to the fixed end plate 106.

[0041] Example 2 further optimizes the steel belt break detection device provided in Example 1. Specifically, as Figures 1 - 3 shown, a compression spring 105 is provided between the broken belt top plate 104 and the fixed end plate 106, and the compression spring 105 provides a stable supporting force for the broken belt top plate 104.

[0042] Further, as Figure 1 shown, the compression spring 105 is sleeved on the outer surface of the screw rod 103, and the screw rod 103 can be used as the guiding shaft of the compression spring 105 to ensure that the compression spring 105 always moves in a straight line during the compression and extension processes without twisting or deviation.

[0043] Further, as Figure 2 shown, a first round hole 4 is provided on the broken belt top plate 104, and the fixing bolt of the rope socket assembly passes through the first round hole 4 to realize the connection between the broken belt top plate 104 and the rope socket assembly, so that the rope socket assembly can push the broken belt top plate 104 when the belt breaks.

[0044] Further, as Figure 1 shown, it further includes an upper end plate 109. A second round hole 3 for the linkage rod 107 to pass through is provided on the upper end plate 109. The second round hole 3 plays a guiding role to ensure the smooth movement of the linkage rod 107. The second round hole 3 provides precise guidance for the linkage rod 107, so that the linkage rod 107 can always remain vertical and stable during the movement, avoiding inaccurate triggering or delay caused by inclination or shaking.

[0045] Embodiment 3 further optimizes the steel belt breakage detection device provided in Embodiment 1 or 2. Specifically, as Figures 1 - 3 shown, the safety switch 110 is installed on the upper end plate 109.

[0046] Furthermore, the safety switch 110 is connected to the main control system of the elevator to stop the elevator when the safety switch 110 is triggered.

[0047] The usage process of the steel belt breakage detection device provided by the present utility model is as follows:

[0048] When the steel belt breaks, the spring in the rope end assembly pushes the breakage top plate 104 towards the fixed end plate 106. At this time, the breakage top plate 104 drives the linkage rod 107 to move, and the linkage rod 107 drives the switch hitting plate 108 to move. The safety switch 110 is toggled by the switch hitting plate 108 to achieve the breakage detection of the steel belt. When the safety switch 110 is triggered, it indicates that the steel belt has broken. After receiving the alarm signal, the elevator main control system will take corresponding safety measures to ensure the safety of passengers.
