Description

Technical Field

[0001] This invention relates to the field of lifting device technology, and in particular to a galvanized steel wire rope balancing lifting device. Background Technology

[0002] Lifting devices are widely used as core equipment, and their performance directly affects work efficiency, safety, and applicable scenarios. Currently, most lifting devices on the market adopt a single-stage lifting structure, with a single drive mechanism driving the lifting components. Due to structural limitations, these devices have a narrow lifting range, making it difficult to meet the high-height handling needs in scenarios such as multi-story factories and high-level assembly. Forcibly increasing the height by lengthening the lifting components will lead to a decrease in device stability and an increased risk of tipping over.

[0003] Meanwhile, the balance control capabilities of existing devices are generally insufficient. Most lifting devices rely on only one-sided drive or a simple double-sided synchronous structure. When carrying materials, uneven driving forces on both sides and asynchronous wire rope winding and unwinding can easily cause the lifting platform to tilt, leading to safety accidents such as material slippage and damage. Some devices with hoisting functions have independent hoisting and lifting mechanisms that need to be operated separately. This is not only cumbersome to operate, but also prone to problems of uncoordinated lifting and hoisting actions, further reducing operational accuracy and efficiency.

[0004] Furthermore, traditional lifting devices mostly use ordinary asynchronous motors for drive, which have low speed control precision and make it difficult to accurately reel in and unleash the wire rope. This is especially problematic when handling precision equipment or fragile materials, as they cannot meet the requirements for stable operation. Moreover, most devices are single-function, only capable of lifting or hoisting materials, unable to meet both operational needs simultaneously. This necessitates the use of multiple devices in tandem, increasing equipment investment costs and space requirements, which is detrimental to companies' ability to control production costs and improve operational efficiency.

[0029] Among them, motor 228 is a servo motor or a stepper motor; motor 21 is a servo motor or a stepper motor.

[0030] like Figure 5 As shown, the lifting mechanism 2 6 has the same structure as the lifting mechanism 1 3. The lifting mechanism 1 3 includes a fixed housing 31, a lifting housing 1 32, a lifting housing 2 33, and a wire linkage mechanism 34. The bottom of the fixed housing 31 is fixedly connected to the top of the base 1. The lifting housing 1 32 is vertically movably connected to the inside of the fixed housing 31. The lifting housing 2 33 is movably connected to the inside of the lifting housing 1 32. The wire linkage mechanism 34 is located inside the fixed housing 31. The wire linkage mechanism 34 is connected to the lifting housing 1 32, the lifting housing 2 33, and the inside of the fixed housing 31. The lower side of the wire linkage mechanism 34 is connected to the synchronous drive mechanism 2.

[0031] like Figure 6 As shown, the wire linkage mechanism 34 includes pulley 341, pulley 342, wire rope 343, mounting groove 344, mounting groove 345, connecting block 346, and pulley 347. Mounting groove 344 is located inside the right side of the lifting housing 32, and pulley 341 is movably connected to the upper side of mounting groove 344.

One end of wire rope 343 is fixedly connected to connecting block 346, and the other end of wire rope 343 is connected to the synchronous drive mechanism 2 via pulley 341, pulley 347, and pulley 342 in sequence.

[0032] like Figure 7 As shown, the synchronous hoisting mechanism 5 includes a second wire rope 51, a first guide wheel 52, a second guide wheel 53, a boom 54, a third guide wheel 55, a third wire rope 56, and a fourth guide wheel 57. The first guide wheel 52 and the second guide wheel 53 are movably connected to the lower left side of the lifting plate 4. One side of the second wire rope 51 is connected to the left side of the synchronous drive mechanism 2, and the other side of the second wire rope 51 is connected to the upper left side of the boom 54 via the first guide wheel 52 and the second guide wheel 53. The third guide wheel 55 and the fourth guide wheel 57 are movably connected to the lower right side of the lifting plate 4. One side of the third wire rope 56 is connected to the right side of the synchronous drive mechanism 2, and the other side of the third wire rope 56 is connected to the upper right side of the boom 54 via the fourth guide wheel 57 and the third guide wheel 55.

[0033] The coordinated control strategy of motor 1 21 and motor 2 228 is as follows: (1) Speed ​​synchronization algorithm: The master-slave control mode is adopted, with motor 1 21 as the master motor and motor 2 228 as the slave motor. The master motor runs at the preset speed, and the speed signal of motor 1 is collected in real time by the encoder (sampling frequency is 100Hz), and the signal is transmitted to the PLC controller. The PLC controller corrects the drive signal of motor 2 in real time by using the PID adjustment algorithm according to the preset synchronization error threshold (≤±0.5r / min) to ensure that the speed of motor 2 is consistent with that of motor 1. When the speed deviation is detected to exceed the threshold, the PLC controller immediately adjusts the output voltage and frequency of motor 2 to quickly compensate for the deviation and achieve high-precision synchronous operation of the two.

[0034] (2) Fault handling mechanism: Speed ​​deviation fault: If the speed deviation between motor 1 21 and motor 2 228 exceeds ±1 r / min within 3 consecutive sampling periods, the system determines it to be a speed deviation fault, immediately activates the alarm device (audio and visual alarm), and simultaneously reduces the speed of the two motors to the preset safe speed (30% of the original speed) and continues to perform PID adjustment; if the deviation is not eliminated after 5 seconds of adjustment, the system automatically stops the operation of the two motors and waits for manual troubleshooting.

[0035] Motor overload fault: Current sensors are installed in the power supply circuits of motor 1 (21) and motor 2 (228) to monitor the motor operating current in real time. When the current exceeds 120% of the motor's rated current and lasts for 2 seconds, it is determined to be an overload fault. The system immediately cuts off the motor power supply, stops operation, and issues an alarm to prevent motor damage due to overload.

[0036] Communication failure: If the communication between the PLC controller and the motor encoder is interrupted for more than 1 second, the system will determine that it is a communication failure, automatically stop the motor and sound an alarm to ensure that the equipment does not run blindly without speed feedback.

[0037] The wire rope parameters are as follows: galvanized steel wire rope with a diameter of 8mm, nominal tensile strength ≥1570MPa, minimum breaking strength ≥37.8kN, suitable for the load requirements of this device (maximum rated load 500kg).

[0038] Motor power parameters: Motor 1 (servo motor): Model SGM7J-08AFC6S, rated power 0.75kW, rated speed 3000r / min, rated torque 2.39N·m, encoder resolution 17-bit to ensure speed control accuracy; Motor 2 (servo motor): Model is the same as Motor 1, with the same parameters, to ensure the performance matching of the two motors and facilitate synchronous control.

[0039] Gear module parameters: The module of transmission gear 1 221, connecting gear 1 223, connecting gear 2 227, and transmission gear 2 229 are all 2.5mm, with a pressure angle of 20°, and the number of teeth are 24, 24, 24, and 24 respectively. The transmission ratio is 1:1 to ensure the smoothness and synchronization of power transmission. The gear precision grade is 6, and the surface roughness Ra≤0.8μm reduces wear and noise during transmission and extends the service life of the device.

[0040] To prevent wire rope overwinding, overload, and power failure protection, the following specific implementation methods are employed:

[0041] (1) Overwind protection: Limit switches (model: LX19-111) are installed on the top of the fixed housing 31 of lifting mechanism 1 3 and lifting mechanism 2 6. When lifting housing 2 33 rises to the maximum stroke (i.e., lifting plate 4 reaches the highest working position), the limit switch is triggered at the top of lifting housing 2 33. The limit switch sends a signal to the PLC controller, and the controller immediately stops the operation of motor 1 and motor 2 to prevent the wire rope from continuing to wind up and causing overwind. At the same time, absolute encoders are installed on the sides of drum 1 23, drum 2 25, drum 3 222 and drum 4 225 to monitor the number of rotations of the drum in real time and calculate the winding and unwinding length of the wire rope in combination with the wire rope diameter. When the winding and unwinding length reaches the preset maximum winding length, the PLC controller issues a warning signal in advance. If winding continues, the motor will stop running immediately, forming a double overwind protection.

[0042] (2) Overload protection: A weight sensor (model: YZC-131) with a range of 0-1000kg and an accuracy of ±0.5%FS is installed at the bottom of the lifting plate 4 to detect the weight of the material in real time. When the detected weight exceeds 110% of the rated load (500kg), the weight sensor sends an overload signal to the PLC controller. The controller immediately stops the motor and activates the audible and visual alarm. At the same time, lifting and hoisting operations are prohibited until the load returns to within the rated range. Combined with the motor overload current monitoring mentioned above, this forms a double overload protection to ensure the safety of the equipment and materials.

[0043] (3) Power failure protection: A UPS uninterruptible power supply (model: C1K) is installed in the power supply circuit of the device. When the external power supply is suddenly interrupted, the UPS immediately supplies power to key control components such as PLC controller, limit switch, and weight sensor to ensure that the controller can receive the signals of each sensor normally. At the same time, an electromagnetic brake is installed in the motor drive circuit. After the power is cut off, the electromagnetic brake immediately engages and locks the motor output shaft and transmission shaft to prevent the lifting plate 4 and the boom 54 from falling due to gravity, thus realizing emergency braking protection after power failure.

[0044] The invention is used in the following ways: It has a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, the material to be transported is first placed stably in the center of the lifting plate 4 to avoid a shift in the center of gravity. This prevents the material from tilting or slipping during subsequent lifting due to instability, which could lead to safety accidents or damage. After placing the material, motor 21 is started. Motor 21 acts as a power source, driving the right-side output shaft to rotate. This output shaft is closely connected to the transmission shaft 24, thereby causing the transmission shaft 24 to rotate synchronously. On the left and right sides of the drive shaft 24, drum 23 and drum 25 are fixedly installed respectively. As the drive shaft 24 rotates, drum 23 and drum 25 begin to operate synchronously, tightening the wire rope 343. During the tightening process, one end of the wire rope 343 is fixedly connected to the connecting block 346, which is firmly fixed to the lower right side of the lifting housing 33. Therefore, the tension of the wire rope 343 is transmitted to the lifting housing 33 through the connecting block 346, thereby pushing the lifting housing 33. The lifting housing 32 moves upward inside the fixed housing 31, and simultaneously, the lifting housing 32 also moves upward inside the fixed housing 31. This multi-stage lifting mechanism, consisting of the fixed housing 31, the lifting housing 32, and the lifting housing 33, greatly expands the lifting range, meeting the material handling needs at different heights and suitable for various complex working scenarios. As the lifting platform 4 rises, the synchronous hoisting mechanism 5 also begins to function, starting the second motor 228. The second motor 228, as a servo motor or stepper motor, has high-precision speed control capabilities and can accurately drive the left... The side output shaft rotates, and this output shaft is connected to the center of the right side of the transmission sleeve 226, which drives the transmission sleeve 226 to rotate. The drum 225, which is fixedly connected to the outside of the left side of the transmission sleeve 226, rotates accordingly. At the same time, the drum 222 also rotates synchronously under the drive of the transmission shaft 24. The rotation of the drum 225 and the drum 222 realizes the winding and unwinding operation of the wire rope 56 and the wire rope 51. One side of the wire rope 51 is connected to the left side of the synchronous drive mechanism 2, and the other side passes through the guide wheel 52 and the guide wheel 53 in sequence before connecting to the upper left side of the boom 54.One side of wire rope 56 is connected to the right side of the synchronous drive mechanism 2, and the other side passes through guide wheel 4 57 and guide wheel 3 55 before connecting to the upper right side of the boom 54. The precise winding and unwinding of wire ropes 56 and 51 by drums 4 225 and 3 222 allows for flexible adjustment of the boom 54's height, meeting the lifting needs of materials at different heights. Furthermore, the installation of lifting mechanisms 1 3 and 2 6 is crucial for ensuring material balance. Since lifting mechanism 2 6 has the same structure as lifting mechanism 1 3, driven by motor 1 21, they can achieve synchronous lifting and unwinding of both sides of the lifting plate 4. During lifting, the wire ropes 1 343 on both sides are simultaneously tightened or loosened, keeping the lifting plate 4 horizontal and effectively ensuring the balance of materials during lifting, preventing damage or accidents caused by tilting. Simultaneously, the synchronous winding and unwinding of wire ropes 2 51 and 56 also ensures the boom 54 remains balanced when lifting materials, further improving the safety and stability of material handling.
