Description

Technical Field

[0001] This invention relates to the field of elevator safety technology, specifically to a self-lubricating, wear-free elevator safety clamp. Background Technology

[0002] Elevator safety brakes are an important safety protection device for elevators. Under the control of the speed governor, when the elevator speed exceeds the set limit or the suspension rope breaks or slackens, the elevator safety brake will bring the car to an emergency stop and clamp it onto the guide rail. The elevator safety brake provides effective protection for the safe operation of the elevator, preventing the elevator car from derailing or passengers from accidentally entering the elevator shaft. The elevator safety brake consists of two parts: a lifting mechanism and a braking mechanism. It is usually installed on the elevator car or counterweight. When the elevator malfunctions, the speed governor will drive the safety brake to actuate, achieving an emergency stop by clamping the guide rail.

[0003] Existing elevator safety brakes suffer from various malfunctions, including their own, wedge block, lifting mechanism, and speed governor failures. Most of these malfunctions are caused by dust, debris, and lumpy impurities falling into the elevator shaft during operation, leading to blockages and wear on the internal equipment of the safety brakes. Although the safety brakes can still function under these conditions, they pose certain hidden dangers and compromise passenger safety. Furthermore, long-term wear and tear increases the maintenance costs of the elevator safety brakes, resulting in resource waste.

[0004] 1. Patent document CN115872254B discloses an elevator safety clamp. The above patent has the characteristics of superior braking performance, high reliability, good working stability and low production cost. However, the above patent cannot achieve the self-cleaning function of the elevator safety clamp.

[0005] 2. Patent document CN1182017C discloses an elevator speed limiting safety clamp. The above patent achieves a very simple structure, saves the space of the top floor machine room, and eliminates the need for two steel wire ropes and tensioning wheels running back and forth from the top floor to the pit, reducing production costs and simplifying installation. However, the above patent cannot achieve the function of cleaning and lubrication without interference.

[0006] 3. Patent document CN112279034B discloses an elevator safety clamp. The above patent reduces braking impact, increases the braking effect of the safety clamp, and reduces equipment wear. However, the above patent cannot achieve the function of monitoring the speed and performance of the elevator safety clamp.

[0007] 4. Patent document CN105905741B discloses an elevator safety clamp. The above patent consists of a left wedge and a right brake wheel. When braking, it clamps the elevator guide rail from both sides to make the elevator guide rail evenly stressed and prevent the guide rail from deforming. When braking, the connecting column moves upward along the waist hole to increase the pressure between the brake wheel and the elevator guide rail and improve the braking force. At the same time, it limits the vertical movement range of the connecting column so that the brake plate will not detach from the safety clamp body when braking. However, the above patent cannot achieve the function of absorbing dust and debris during the use of the elevator safety clamp.

[0008] In summary, the aforementioned patents cannot achieve the self-cleaning function of the elevator safety clamp, the function of cleaning and lubrication without interference, the function of monitoring the speed and performance of the elevator safety clamp, or the function of absorbing dust and debris during the use of the elevator safety clamp. This leads to problems such as equipment failure due to blockage, equipment wear caused by sand and oil, rusting of the elevator safety clamp, overheating during operation, delayed action of the elevator safety clamp, and delayed detection of blockages during long-term use.

[0009] Therefore, this application proposes a self-lubricating, wear-free elevator safety clamp that can achieve self-cleaning, cleaning and lubrication without interference, speed and performance monitoring, and dust and debris absorption during use. Summary of the Invention

[0055] The cleaning module 5 includes a first spray nozzle 10, a second spray nozzle 11, a pressurization module 9, and a water storage chamber 12;

[0056] A first spray nozzle 10 is installed on the upper part of the outer wall of the base 1, a second spray nozzle 11 is installed in the middle of the inner wall of the base 1, a pressurization module 9 is installed on the upper part of the outer wall of the base 1, and a water storage chamber 12 is installed on the upper part of the outer wall of the base 1.

[0058] A second base 21 is installed on the upper part of the outer wall of the base 1. A second motor 22 is installed on the right side of the inner wall of the second base 21. A push rod 16 is installed in the middle of the inner wall of the second base 21. A piston 15 is installed in the middle of the inner wall of the second base 21.

The second motor 22 is connected to a processor 39 through a signal line. The second motor 22 is connected to a power supply 40 through a signal line.

[0059] Furthermore, when the elevator safety clamp needs cleaning, the cleaning module 4 pressurizes the liquid flowing out of the water storage chamber 12 through the pressurization module 9, and sprays the liquid onto the elevator safety clamp through the first spray port 10 and the second spray port 11, realizing the self-cleaning function of the elevator safety clamp. This solves the problems of equipment failure caused by blockage and equipment wear caused by sand and oil stains during long-term use, improves the service life of the equipment, enhances the safety performance during use, and reduces the cost of maintaining the equipment.

[0060] Example 2

[0061] Please see Figure 1 , Figure 3 and Figure 5 A self-lubricating, wear-free elevator safety clamp, wherein the inner wall of the water storage chamber 12 is equipped with a partition module including: a first valve 23, a second valve 24, a first storage chamber 25, and a second storage chamber 26;

[0062] A first valve 23 is installed on the left side of the inner wall of the water storage chamber 12, and a second valve 24 is installed on the right side of the inner wall of the water storage chamber 12. A first storage chamber 25 is installed on the left side of the inner wall of the water storage chamber 12, and a second storage chamber 26 is installed on the right side of the inner wall of the water storage chamber 12.

[0064] The water storage chamber 12 has a first base 27 installed on the left side of its inner wall. A fixed iron core 28 is installed on the upper side of the inner wall of the first base 27.

[0065] The first storage chamber 25 contains stainless steel cleaner, and the second storage chamber 26 contains lubricant.

[0066] Furthermore, when the cleaning module 5 is working, the processor 39 controls the connection between the first valve 23, the second valve 24, and the power supply 40 according to the different cleaning needs of the elevator safety gear. When the elevator safety gear needs stainless steel cleaner, the processor 39 controls the first valve 23 to open and the second valve 24 to close.

[0067] Example 3

[0068] Please see Figure 1 and Figure 6 A self-lubricating, wear-free elevator safety clamp, wherein a dust collection module 7 is installed on the upper part of the outer wall of the base 1, and the dust collection module 7 includes a dust collection port 32, a storage chamber 34 and a suction component;

[0069] A dust suction port 32 is installed on the upper side of the outer wall of the base 1, a storage chamber 34 is installed on the upper part of the outer wall of the base 1, and an air suction component is installed on the upper part of the outer wall of the base 1.

[0070] The air intake assembly includes an impeller 35, a connecting shaft 36, and a first motor 33;

[0071] An impeller 35 is installed on the upper part of the outer wall of the base 1, a connecting shaft 36 is installed on the upper part of the outer wall of the base 1, a first motor 33 is installed on the upper part of the outer wall of the base 1, the impeller 35 is connected to the first motor 33 through the connecting shaft 36, the first motor 33 is connected to the processor 39 through a signal line, and the first motor 33 is connected to the power supply 40 through a signal line.

[0072] Furthermore, during elevator use, debris, dust, particulate solids, and other impurities may appear in the environment. Through the operation of the dust collection module 7, these impurities are absorbed during use. The processor 39 controls the air suction component, and the first motor 33 drives the impeller 35 to rotate, creating an air pressure difference inside and outside the dust collection module 7. This draws external air inward, sucking the impurities into the storage chamber 34 before they fall into the elevator safety clamp. This achieves the function of absorbing dust and debris during the use of the elevator safety clamp, solving the problems of the elevator safety clamp being blocked by debris and the increased wear due to debris accumulation during operation. It can increase the service life of the elevator safety clamp, reduce the cost of maintaining the elevator safety clamp, and improve the safety and reliability of use.

[0073] Example 4

[0074] Please see Figure 1 and Figure 7 A self-lubricating, wear-free elevator safety clamp, wherein a monitoring module 8 is installed on the upper side of the outer wall of the base 1, and the monitoring module 8 includes: a speed monitoring component 37, a weight monitoring component 38 and a sound monitoring component 46;

The speed monitoring component 37 is connected to the processor 39 via a signal line, the weight monitoring component 38 is connected to the processor 39 via a signal line, the sound monitoring component 46 is connected to the processor 39 via a signal line, and the processor 39 is connected to the power supply 40 via a signal line.

[0076] The speed sensor contains a permanent magnet, a Hall element, a rotating mechanism, an output plug, and a conversion circuit. During the movement of the elevator safety clamp, the permanent magnet is rotated. When the rotating permanent magnet passes through the Hall element, it generates a periodically changing magnetic field in the Hall element, causing a change in the output voltage of the Hall element. After being processed by the conversion circuit, the changing voltage signal is transmitted to the processor 39.

[0077] The accelerometer is equipped with a mass block, a damper, an elastic element, a sensitive element, and an adaptation circuit. Based on Newton's second law, when the elevator safety clamp experiences acceleration, the mass block will be subjected to inertial force. This force causes the elastic element to deform, and then the sensitive element converts the mechanical deformation into an electrical signal. The adaptation circuit processes the electrical signal, and the processed electrical signal proportional to the acceleration is transmitted to the processor 39.

[0078] The weight monitoring component 38 is internally equipped with a resistance strain gauge, an A / D converter, a signal amplifier, and a microprocessor;

[0079] During the use of the elevator safety clamp, under the action of the dust suction module 7, the dust particles and dust are sucked into the storage chamber 34. The resistance strain gauge undergoes elastic deformation with the change of weight, and the resistance value of the resistance strain gauge changes accordingly. The physical strain is measured by measuring the change of resistance. The signal is processed by the A / D converter, amplified by the signal amplifier, and then transmitted to the processor 39.

[0080] The sound monitoring component 46 is internally equipped with a condenser electret microphone, an A / D converter, and a data acquisition unit.

[0081] Sound waves cause the electret film inside the condenser microphone to vibrate, resulting in a change in capacitance and generating a small voltage. The signal, after being processed by an A / D converter and a data acquisition unit, is transmitted to the processor 39.

[0082] Furthermore, during the use of the elevator safety brake, the monitoring module 8 monitors the changes in speed, acceleration, weight, and sound of the elevator safety brake in real time through the speed monitoring component 37, weight monitoring component 38, and sound monitoring component 46. The information is transmitted to the processor 39 via signal lines. By analyzing the data, it is determined whether the elevator safety brake is in normal working condition. This realizes the function of monitoring the speed and performance of the elevator safety brake, solving the problems of untimely action of the elevator safety brake and untimely detection of obstruction by debris. It can slow down the elevator in advance and detect changes in the weight of the elevator safety brake in a timely manner, reducing the occurrence of accidents.

[0089] A monitoring module 8 is installed on the upper side of the outer wall of the base 1. The monitoring module 8 includes: a speed monitoring component 37, a weight monitoring component 38, and a sound monitoring component 46.

[0090] A speed monitoring component 37, a weight monitoring component 38, and a sound monitoring component 46 are installed on the upper side of the outer wall of the base 1. The speed monitoring component 37 is connected to the processor 39 via a signal line, the weight monitoring component 38 is connected to the processor 39 via a signal line, the sound monitoring component 46 is connected to the processor 39 via a signal line, and the processor 39 is connected to the power supply 40 via a signal line.

[0091] The speed sensor contains a permanent magnet, a Hall element, a rotating mechanism, an output plug, and a conversion circuit. During the movement of the elevator safety clamp, the permanent magnet is rotated. When the rotating permanent magnet passes through the Hall element, it generates a periodically changing magnetic field in the Hall element, causing a change in the output voltage of the Hall element. After being processed by the conversion circuit, the changing voltage signal is transmitted to the processor 39.

[0092] The accelerometer is equipped with a mass block, a damper, an elastic element, a sensitive element, and an adaptation circuit. Based on Newton's second law, when the elevator safety clamp experiences acceleration, the mass block will be subjected to inertial force. This force causes the elastic element to deform, and then the sensitive element converts the mechanical deformation into an electrical signal. The adaptation circuit processes the electrical signal, and the processed electrical signal proportional to the acceleration is transmitted to the processor 39.

[0093] The weight monitoring component 38 is internally equipped with a resistance strain gauge, an A / D converter, a signal amplifier, and a microprocessor;

[0094] During the use of the elevator safety clamp, under the action of the dust suction module 7, the dust particles and dust are sucked into the storage chamber 34. The resistance strain gauge undergoes elastic deformation with the change of weight, and the resistance value of the resistance strain gauge changes accordingly. The physical strain is measured by measuring the change of resistance. The signal is processed by the A / D converter, amplified by the signal amplifier, and then transmitted to the processor 39.

[0095] The sound monitoring component 46 is internally equipped with a condenser electret microphone, an A / D converter, and a data acquisition unit.

[0096] Sound waves cause the electret film inside the condenser microphone to vibrate, resulting in a change in capacitance and generating a small voltage. The signal, after being processed by an A / D converter and a data acquisition unit, is transmitted to the processor 39.

[0097] Furthermore, if impurities appear inside the elevator safety gear, causing wear and noise during operation, the sound monitoring component 46 detects the sound change and transmits the signal to the processor 39. Upon receiving the signal, the processor controls the cleaning module 5 to clean the inside of the elevator safety gear. During elevator operation, the speed monitoring component 37 monitors the elevator's speed and acceleration and transmits the data to the processor 39. If a malfunction occurs in the elevator, the processor 39 judges the current situation based on changes in speed and acceleration and issues a command to the elevator safety gear in advance to brake the elevator. This achieves quick and proactive handling of elevator malfunctions, increases the elevator's safety performance, and enhances the user's sense of security.

[0098] Working principle: When impurities appear inside the elevator safety gear, wear occurs during operation, generating noise. The sound monitoring component 46 detects the sound change and transmits the signal to the processor 39. After receiving the signal, the processor controls the cleaning module 5 to clean the inside of the elevator safety gear. The cleaning module 4 pressurizes the liquid flowing out of the water storage chamber 12 through the pressurization module 9 and sprays the liquid onto the elevator safety gear through the first spray port 10 and the second spray port 11. When the cleaning module 5 is working, depending on the cleaning work required by the elevator safety gear, the processor 39 controls the passage between the first valve 23 and the second valve 24 and the power supply 40. When the elevator safety gear needs stainless steel cleaner, the processor 39 controls the first valve 23 to open and the second valve 24 to close. When the elevator safety gear needs lubricant, the processor 39 controls the first valve 23 to close and the second valve 24 to open.

[0099] During elevator use, debris, dust, particulate solids and other impurities may appear in the environment. The dust collection module 7 absorbs the impurities during use. The processor 39 controls the air suction component, and the first motor 33 drives the impeller 35 to rotate, creating an air pressure difference inside and outside the dust collection module 7, which draws the outside air inward and sucks the impurities into the storage room 34 before they fall into the elevator safety clamp.

[0100] During the use of the elevator safety brake, the monitoring module 8 monitors the changes in speed, acceleration, weight and sound of the elevator safety brake in real time through the speed monitoring component 37, weight monitoring component 38 and sound monitoring component 46, and transmits the information to the processor 39 through the signal line. By analyzing the data, it can be determined whether the elevator safety brake is in normal working condition at the current state.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
