The steel wire rope 2 is connected to the fixed pulley 1 in a cooperative manner. The buffer guide device 10 is arranged on the side of the steel pipe rack 5 close to the fixed pulley 1 in the horizontal direction.

[0022] like Figure 3 and Figure 5 As shown, a rectangular tube 7 is connected to the bottom of the steel pipe frame 5 to increase the stability of the steel pipe frame 5 .
[0023] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, a universal wheel 8 is connected to the bottom of the rectangular tube 7.
[0024] like Figure 2 , Figure 3 and Figure 5 As shown, a counterweight block 6 is arranged at the bottom of the steel pipe frame 5 .
[0025] like Figure 1 , Figure 3 and Figure 7 As shown, an anti-collision sensor 9 is provided on one side of the steel pipe frame 5 close to the fixed pulley 1 in the horizontal direction.
[0026] like Figures 3 to 6 As shown, the buffer guide device 10 is arranged in an array, including a spring cylinder 101, a guide rod 102 and a top block 103. The spring cylinder 101 is connected to the steel pipe frame 5, and the guide rod 102 is connected to the spring cylinder 101. The steel pipe frame 5 is provided with a through hole, and the guide rod 102 passes through the through hole. The top block 103 is connected to one end of the guide rod 102 away from the spring cylinder 101.
[0027] like Figure 3 and Figure 4 As shown, the guide rod 102 is provided with a guide wheel 104, which can provide a buffer and reduce friction during the process of lifting and lowering the ALC slats.
[0028] An efficient hoisting method for ALC strips, using an efficient hoisting tool for ALC strips to hoist the ALC strips, specifically comprising the following steps: Step 1: Slowly release one end of the wire rope 2 from the winch 4. The operator holds the free end of the wire rope 2 and passes it through the fixed pulley 1. Then, he walks to the ALC slat to be hoisted and hangs the wire rope 2 on the ALC slat. The contact point between the wire rope 2 and the slat is well protected to prevent scratching the surface of the slat. Step 2: Start the winch 4, the winch 4 starts to reel in, the wire rope 2 is gradually tightened, and the ALC slat is lifted off the ground through the connection with the fixed pulley 1. If the ALC slat tilts at this time, stop the lifting in time and adjust the binding position of the wire rope 2; Step 3: As the slats continue to rise, when the slats are close to the side of the steel pipe frame 5 close to the fixed pulley 1 in the horizontal direction, if there is a slight deviation, the guide rod 102, under the elastic force of the spring tube 101, drives the top block 103 and the guide wheel 104 to buffer and straighten the slats, and uses the guide wheel 104 to reduce the friction between the slats and the device, and then starts to transfer. At the same time, the anti-collision sensor 9 monitors the surrounding environment in real time. Once it senses that there is an obstacle approaching near the lifting path, it immediately sends an alarm signal to the operator, and the operator quickly stops lifting; Step 4: Push the handrail 3, unlock the universal wheel 8, move the lifting tool, adjust the position of the ALC slats, and after the slats are lifted to the predetermined installation height and horizontal position, stop the operation of the winch 4, and the construction personnel quickly fix the slats; Step 5: After confirming that the ALC slats are firmly installed, untie the binding between the wire rope 2 and the slats, operate the winch 4 to slowly release the rope, retract the wire rope 2 to the initial state, move the lifting tool to the starting point of the next lifting, and prepare for the lifting operation of the next ALC slat.
[0029] Principle and operation process The lower part of the steel pipe frame 5 is vertically projected into a rectangle, and the upper part is triangular. The rectangular structure is conducive to providing a stable support plane at the bottom, evenly dispersing the weight of the equipment and various forces generated during the lifting process; the upper triangular structure can enhance the ability of the entire frame to resist the lateral force brought by the fixed pulley 1. The fixed pulley 1 is placed on the top of the steel pipe frame 5, changing the direction of the tension of the wire rope 2. One end of the wire rope 2 is connected to the winch 4, and the other end is hung with the ALC strip.
[0030] The buffer guide device 10 array is distributed on one side of the steel pipe frame 5 close to the fixed pulley 1. The spring cylinder 101 serves as an elastic energy storage element. When the ALC slats are slightly offset or shaken during lifting due to factors such as wind force and uneven lifting speed, and touch the buffer guide device 10, the guide rod 102 is forced to compress the spring cylinder 101, and the spring absorbs the impact energy to buffer the collision force; at the same time, the top block 103 and the guide wheel 104 at the end of the guide rod 102 work together to straighten the slats with the help of the rebound force of the spring cylinder 101, reducing the shaking without damaging the ALC slats. The guide wheel 104 can also effectively reduce the friction resistance between the slats and the device to avoid surface scratches.
[0031] The anti-collision sensor 9 installed on the steel pipe rack 5 captures the reflected signal when obstacles appear around the lifting path. Once the distance is too close and there is a risk of collision, the alarm system is immediately triggered to send out sound and light warnings to the operator. The operator can then brake the winch 4 in time and stop the lifting action, ensuring the safety of personnel, equipment and building structures on the construction site.
[0032] The counterweight block 6 added at the bottom of the steel pipe frame 5 can adjust the center of gravity of the entire lifting tool. When lifting ALC slats of different weights, the counterweight blocks 6 of different weights can be selected to offset the overturning moment caused by the eccentricity of the slats and the lifting eccentricity, so that the equipment always remains stable.
[0033] On one hand, the rectangular tube 7 can enhance the bottom structural rigidity of the steel tube frame 5 to resist the lateral tension and torsion generated by lifting; on the other hand, it can serve as a carrier of the universal wheel 8.
[0034] When carrying out the hoisting work, the operator controls the winch 4 to start, releases one end of the wire rope 2, and after releasing a sufficient length, holds the free end of the wire rope 2, places the wire rope 2 along the groove of the fixed pulley 1, and reaches the ALC slat to be hoisted after the hand-held wire rope 2 passes through the fixed pulley 1; when it arrives next to the ALC slat, the ALC slat is hung according to the preset hoisting point position of the slat, and then the hoisting is started, and the operator starts the winch 4, the winch 4 starts to reel in at a uniform speed, and the wire rope 2 is gradually tightened, and the tension is converted into a vertical lifting force through the fixed pulley 1, and the ALC slat is slowly lifted off the ground; if the slat is found to be tilted or shaking, the pause button is immediately pressed to stop the hoisting, and the operator adjusts the hanging position of the wire rope 2. After the adjustment is completed, the winch 4 is started again to slowly lift the slat; as the slat continues to rise, when the slat is close to the side of the steel pipe frame 5 close to the fixed pulley 1 in the horizontal direction, if there is a slight deviation, the guide rod 102 in the ALC Under the pressure of the C strip, the pressure is transmitted to the spring tube 101. At this time, the spring tube 101 is in a stressed state and stores energy at the same time. The top block 103 presses against the strip, and the guide wheel 104 rolls accordingly to buffer the impact of the collision. The strip is straightened with the help of the spring's rebound force to reduce the friction resistance and ensure that the strip rises along the vertical path. At the same time, once the anti-collision sensor 9 senses that an obstacle is approaching near the lifting path, the sensor instantly triggers the alarm system and sounds an alarm. After hearing the alarm, the operator observes the surrounding environment in time to ensure that the lifting work continues along the safe route. The lifting tool is pushed to the bottom of the predetermined installation position of the ALC strip. After reaching the predetermined position, the winch 4 is stopped, and the construction personnel carry out the fixed installation of the ALC strip. After confirming that the ALC strip is firmly installed, the wire rope 2 is untied from the strip, and then the rope is slowly retracted to the initial state. After retracting the wire rope 2, the lifting tool is moved to the starting point of the next lifting through the universal wheel 8.
[0035] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
