Description

Technical Field

[0001] This utility model relates to the field of elevator compensation chain technology, specifically to a smart elevator detection and compensation device for working status. Background Technology

[0002] In high-rise building elevator systems, the compensating chain is a key component that balances the weight variations of the traction steel wire ropes on both sides of the car and counterweight. Its stable operation directly affects the safety and comfort of the elevator system. In existing technologies, the compensating chain is typically fixed at both ends to the bottom of the car and below the counterweight frame using simple U-bolts or fixing clamps. This connection method forms the basic guarantee for the normal operation of the elevator.

[0003] However, this traditional fixing method has significant safety hazards. Because the compensating chain is constantly suspended and swinging during elevator operation, its inherent fixing structure lacks an effective anti-detachment locking mechanism, making it prone to loosening or even disengagement under long-term alternating stress. More seriously, the compensating chain suspended in the shaft can dynamically interfere with tangled cables, foreign objects, or building structures during high-speed operation, posing a significant risk of being hooked or entangled. Once such a malfunction occurs, it will not only instantly disrupt the elevator system's balance, causing abnormal noises and vibrations, but may also lead to the compensating chain breaking, ultimately causing equipment shutdown or even a safety accident.

[0004] Therefore, this utility model proposes a device for compensating for the detection working status of intelligent elevators. Utility Model Content

[0005] The purpose of this utility model is to provide a compensation device for detecting the working status of an intelligent elevator, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a compensation device for detecting the working status of an intelligent elevator, including a connecting bottom beam, a fixed box below the connecting bottom beam, a lifting ring at the bottom of the fixed box, a compensation chain suspended below the lifting ring, an early warning unit for detecting the working status of the compensation chain inside the fixed box, a through groove inside the compensation chain, claws on both sides of the through groove, and an anti-detachment unit on the side of the fixed box for pushing the two claws to simultaneously engage with the through groove.

[0006] Preferably, the warning unit includes a sliding column located at the upper end of the lifting ring. A spring is provided on the outside of the sliding column. The two ends of the spring are fixedly connected to the end cap of the sliding column and the bottom of the fixed box, respectively. A contact end is provided at the end of the sliding column. End piece 1 and end piece 2 are provided above and below the contact end, respectively. End piece 1 and end piece 2 are electrically connected to the transmission box on the outer wall of the fixed box. When the contact end touches end piece 1, the transmission box sends an elevator stop signal to the main control terminal. When the contact end touches end piece 2, the transmission box sends an elevator stop signal to the main control terminal.

[0007] Preferably, spring one has a predetermined elastic force, which can meet the normal tension required by the compensation chain during elevator operation. When the contact end is not in contact, the tension generated by the movement between end piece one and end piece two is within the normal tension error range of the compensation chain.

[0008] Preferably, the anti-detachment unit includes a connecting column located inside the gripper, the end of the connecting column being fixedly connected to the fixing box, the side of the fixing box being provided with an electric push rod, the end of the electric push rod being provided with a bracket, the two protruding parts of the bracket being inclined, and the inner wall of the inclined area being in contact with the gripper.

[0009] Preferably, both the electric push rod and the transmission box are electrically connected to the main controller. After the transmission box sends a stop signal, the electric push rod starts automatically and drives the bracket to move closer to the fixed box.

[0010] Preferably, a buffer block is provided inside the through groove, and a second spring is provided above the buffer block. The other end of the second spring is fixedly connected to the inner wall of the compensation chain.

[0011] This utility model has at least the following beneficial effects:

[0012] This invention achieves real-time monitoring and active protection of the compensating chain's working status by incorporating an early warning unit and an anti-detachment unit. When the tension on the compensating chain exceeds the predetermined elastic force range of spring one during elevator operation, the contact end will collide with end piece one or end piece two, triggering the transmission box to send a stop signal to the main control terminal, effectively avoiding the risk of compensating chain breakage due to overload or slack. Simultaneously, the anti-detachment unit drives the bracket to move via an electric push rod, causing the grippers to tightly engage in the through groove of the compensating chain. Combined with the elastic support of the buffer block and spring two, this ensures both the normal expansion and contraction requirements of the compensating chain and prevents it from detaching from the fixed structure due to swaying or interference from foreign objects. This dual protection mechanism significantly improves the safety and reliability of the elevator system, reducing equipment failure rates and maintenance costs. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a compensation device for detecting the working status of an intelligent elevator, including a connecting bottom beam 1, which is located at the bottom of the counterweight and the elevator car, and is used to connect the two ends of a compensation chain 4. A fixed box 2 is provided below the connecting bottom beam 1 and fixedly connected thereto. A lifting ring 3 is provided at the bottom of the fixed box 2, and the compensation chain 4 is suspended below the lifting ring 3. An early warning unit for detecting the working status of the compensation chain 4 is provided inside the fixed box 2. A through groove 5 is provided inside the compensation chain 4, and grippers 6 are provided on both sides of the through groove 5. An anti-detachment unit is provided on the side of the fixed box 2 to push the two grippers 6 into the through groove 5 simultaneously.

[0019] The early warning unit can detect in real time whether the tension of the compensation chain 4 is within the normal range, thereby effectively monitoring the working status of the elevator; the anti-detachment unit can dynamically lock the compensation chain 4 in case of an accident, which can effectively prevent the compensation chain 4 from hooking or detaching from foreign objects in the shaft during high-speed swing.

[0020] The warning unit includes a sliding column 7 located at the upper end of the lifting ring 3. The sliding column 7 is slidably connected to the fixed box 2 and its bottom end is fixedly connected to the lifting ring 3. A spring 8 is provided on the outside of the sliding column 7. The two ends of the spring 8 are fixedly connected to the end cap of the sliding column 7 and the bottom of the fixed box 2, respectively. A contact end 9 is provided at the end of the sliding column 7 and is fixedly connected thereto. A first end piece 10 and a second end piece 11 are provided above and below the contact end 9, respectively. Both the first end piece 10 and the second end piece 11 are electrically connected to the transmission box on the outer wall of the fixed box 2. The side of the transmission box is fixedly connected to the fixed box 2. When the contact end 9 touches the first end piece 10, the transmission box sends an elevator stop signal to the main control terminal; when the contact end 9 touches the second end piece 11, the transmission box sends an elevator stop signal to the main control terminal. Spring 8 has a predetermined elastic force, which can meet the normal tension required by the compensation chain 4 during elevator operation. When the contact end 9 is not in contact, the tension generated by the movement between end piece 10 and end piece 11 is within the normal tension error range of the compensation chain 4.

[0021] The anti-detachment unit includes a connecting post 12 located inside the gripper 6. The connecting post 12 is slidably connected to the gripper 6. The end of the connecting post 12 is fixedly connected to the fixing box 2. The side of the fixing box 2 is provided with an electric push rod 13 and fixedly connected to it. The end of the electric push rod 13 is provided with a bracket 14 and fixedly connected to it. The two protruding parts of the bracket 14 are inclined, and the inner wall of the inclined area is in contact with the gripper 6. The inner wall surface of the bracket 14 and the gripper 6 have a magnetic attraction force that attracts each other. In the non-clamping state, it will not affect the small-amplitude swing of the compensation chain 4.

[0022] Both the electric push rod 13 and the transmission box are electrically connected to the main controller. When the transmission box sends a stop signal, it indicates that the tension of the compensation chain 4 is outside the normal range and further safety measures need to be taken. At this time, the electric push rod 13 starts automatically and drives the bracket 14 to move closer to the fixed box 2. Then, the bottom end of the clamp 6 is driven into the through slot 5 by the blocking effect between the inclined surface of the bracket 14 and the clamp 6. The clamp 6 supports the compensation chain 4 which may disengage, thus improving the safety of elevator operation.

[0023] Furthermore, a buffer block 15 is provided inside the through groove 5. The buffer block 15 is slidably connected to the compensation chain 4, and a second spring 16 is fixedly connected above the buffer block 15. The other end of the second spring 16 is fixedly connected to the inner wall of the compensation chain 4. When the anti-derailment unit is activated, the gripper 6 will momentarily compress the buffer block 15. The elasticity of the second spring 16 will provide buffering force for the compression, which helps to reduce the impact force at the moment of contact between the gripper 6 and the compensation chain 4, avoids local damage to the compensation chain 4 due to rigid collision, and reduces interference with the overall stability of the elevator system. When the elevator returns to normal operation, the reset action of the second spring 16 can push the buffer block 15 back to its initial position, providing reliable protection for the next anti-derailment action. This structure not only ensures the timeliness of the anti-derailment function but also extends the service life of the compensation device.

[0024] Working principle:

[0025] When the elevator is running, the compensating chain 4 is in a suspended swing state and is subjected to alternating stress. The spring 8 in the warning unit undergoes elastic deformation according to the tension change of the compensating chain 4, causing the sliding column 7 to slide up and down within the fixed box 2. When the tension exceeds the normal range, for example, when the compensating chain 4 hooks onto a foreign object, it pulls the contact end 9 down to contact the end piece 11; or when the compensating chain 4 ages and drags on the ground after long-term use, the contact end 9 will be lifted by the spring 8 to contact the end piece 10. Both of these situations will trigger the transmission box to send a stop signal to the main control terminal. At this time, the electric push rod 13 will start immediately, driving the bracket 14 to move towards the fixed box 2.

[0026] The inclined extension of bracket 14, through mechanical resistance, pushes two grippers 6 to simultaneously embed into the through slot 5. During insertion, grippers 6 first contact buffer block 15, compressing spring 16 to generate buffering force, reducing impact damage to the compensation chain 4. Once grippers 6 are fully embedded in the through slot 5, they mechanically lock the compensation chain 4, preventing it from disengaging or snagging with foreign objects in the shaft. After the elevator malfunction is resolved, the main controller releases the stop signal, the electric push rod 13 resets, driving bracket 14 to retract. Grippers 6, under the reset action of spring 16, exit the through slot 5, and the compensation device returns to normal monitoring status. The entire process, through the dual protection of mechanical structure and electrical control, achieves real-time monitoring of the compensation chain 4's operating status and dynamic protection in abnormal situations.

[0027] Compared to existing technologies, the intelligent elevator monitoring and compensation device proposed in this invention has significant advantages. Traditional compensation chain 4 fixing methods lack effective status monitoring and anti-detachment mechanisms, making them prone to loosening due to alternating stress during long-term operation, and even snagging on foreign objects in the shaft, leading to serious consequences such as chain breakage. This device, however, monitors the tension changes of the compensation chain 4 in real time through an early warning unit. When the tension exceeds the normal range, a stop signal is immediately triggered, and the anti-detachment unit automatically activates, using a mechanical locking structure to prevent the compensation chain 4 from detaching, effectively avoiding the safety hazards of traditional fixing methods. Furthermore, the combined design of the buffer block 15 and spring 16 reduces the impact force when the gripper 6 engages, protecting the compensation chain 4 from damage and extending the device's service life. Through the synergistic effect of mechanical and electrical control, this device achieves comprehensive monitoring and dynamic protection of the elevator compensation chain 4's working status, significantly improving the safety and reliability of elevator operation.
