[0045] like Figure 1 As shown, this embodiment provides a hoisting device, which includes a lifting frame 1, an adsorption mechanism 2, a counterweight mechanism 3 and a lifting mechanism 4. The adsorption mechanism 2 includes an adjustment driver 21 and an adsorption member 22. One end of the lifting frame 1 is provided with a mounting portion 11, and the adsorption member 22 is rotatably connected to the mounting portion 11. The adjustment driver 21 can drive the adsorption member 22 to rotate relative to the lifting frame 1. When the adsorption member 22 rotates, the pitch angle of the adsorption member 22 relative to the horizontal direction can be adjusted. The counterweight mechanism 3 includes a counterweight driver and a counterweight assembly 31. The counterweight driver can drive the counterweight assembly 31 to slide relative to the mounting portion 11. When the counterweight assembly 31 slides, the gear state of the lifting frame 1 can be adjusted. The lifting mechanism 4 can drive the lifting frame 1 to rise and fall.

[0046] In this embodiment, the adsorption mechanism 2 includes an adjustment driver 21 and an adsorption member 22. A mounting portion 11 is provided at one end of the lifting frame 1. The adsorption member 22 is rotatably connected to the mounting portion 11. During the construction process, the mounting portion 11 can face the construction area to facilitate the installation of the glass panel adsorbed by the adsorption member 22. The adjustment driver 21 can drive the adsorption member 22 to rotate relative to the lifting frame 1, so that the adsorption member 22 can flexibly adjust its angle without manual operation, and the operation is more convenient and quick. When the adsorption member 22 adsorbs the glass panel, the pitch angle of the adsorption member 22 relative to the horizontal direction can be adjusted by rotating the adsorption member 22, thereby driving the glass panel to rotate to meet the requirements of facade installation at different angles, thereby ensuring the installation quality. The counterweight mechanism 3 includes a counterweight driver and a counterweight assembly 31. The counterweight driver can drive the counterweight assembly 31 to slide relative to the mounting portion 11. When the counterweight assembly 31 slides, the center of gravity position of the lifting frame 1 can be dynamically adjusted, thereby adjusting the gear state of the lifting frame 1, which helps to ensure the balance and stability during the hoisting process and the installation quality of the glass panel. The lifting mechanism 4 can drive the lifting frame 1 to rise and fall to meet the lifting requirements of the glass plate. Through the above arrangement, the lifting device of this embodiment can conveniently and quickly realize the lifting operation of the glass plate.

[0047] The specific structure of the lifting device is described below:

[0048] Specifically, in this embodiment, the adjustment driver 21 includes an adjustment motor and a rotating gear. The adjustment motor is arranged on the lifting frame 1. The output end of the adjustment motor is connected to the rotating gear, which can drive the rotating gear to rotate. The rotating gear is meshed and connected to the tooth portion of the adsorbent 22. The rotation of the rotating gear drives the tooth portion to rotate, so that the adsorbent 22 rotates around its rotation axis. The operator can achieve precise adjustment of the pitch angle of the adsorbent 22 by accurately controlling the speed and direction of the adjustment motor, which helps to maintain the stability of the glass plate during the lifting process and avoid excessive impact or shaking when adjusting the angle, thereby improving the installation accuracy. Among them, the adjustment motor uses a stepper motor or a servo motor, and the specific structure of the adjustment motor is not limited too much here. In other embodiments, the rotation adjustment of the adsorbent 22 relative to the lifting frame 1 can also be achieved by belt drive or chain drive, which is not limited too much here.

[0049] Specifically, the adsorption member 22 is provided with a plurality of adsorption holes, and the plurality of adsorption holes are arranged at intervals. By providing a plurality of adsorption holes, the contact area between the adsorption member 22 and the glass plate can be increased, thereby improving the adsorption force, so that the adsorption member 22 can more firmly adsorb the glass plate, and prevent the glass plate from falling off or sliding during the hoisting process. Among them, the adsorption holes are connected to the air suction end of the exhaust device to facilitate the adsorption and release of the glass plate. The specific working principle of the above device is clear to those skilled in the art, and will not be repeated here.

[0050] It should be noted that the adsorption member 22 is an electromagnetic suction cup or a vacuum suction cup, and no further limitation is made to the specific structure of the adsorption member 22 as long as the above-mentioned functions can be achieved.

[0051] Specifically, the counterweight assembly 31 includes a loading plate, which is slidably connected to the lifting frame 1 along the extension direction of the lifting frame 1, so that the position of the counterweight assembly 31 can be flexibly adjusted as needed, which helps to dynamically balance the center of gravity of the lifting frame 1 during the lifting process and ensure the stability and safety of the lifting operation. The loading plate is provided with a receiving slot for accommodating the counterweight block, which can facilitate the operator to add or remove the counterweight block, thereby adjusting the weight distribution of the entire lifting device, simplifying the replacement process of the counterweight, and improving the construction efficiency.

[0052] It should be noted that the counterweight driver is a pneumatic cylinder or an electric cylinder, which drives the loading plate to slide along the extension direction of the lifting frame 1. The specific structure of the counterweight driver is not limited here, as long as the above-mentioned functions can be achieved.

[0053] More specifically, one of the loading plate and the lifting frame 1 is provided with a slide rail, and the other is provided with a slider that slides with the slide rail. The sliding cooperation between the slide rail and the slider can ensure the stability of the loading plate when sliding on the lifting frame 1, reduce friction and vibration during the sliding process, so that the loading plate can move smoothly along a predetermined trajectory, thereby improving the stability and safety of the lifting operation.

[0054] More specifically, in this embodiment, the slide rail is provided on the lifting frame 1, the slider is provided on the loading plate, and the slider is slidably connected to the slide rail, so that the loading plate can slide relative to the lifting frame 1. In other embodiments, the slide rail is provided on the loading plate, and the slider is provided on the lifting frame 1, that is, as long as the above-mentioned functions can be achieved, the specific positions of the above-mentioned components are not limited too much.

[0055] Specifically, the lifting mechanism 4 is selected from electric hoists, winches or cranes, etc., that is, as long as the above-mentioned functions can be achieved, the specific structure of the lifting mechanism 4 is not limited too much.

[0056] like Figure 1-Figure 8 As shown, this embodiment also provides a hoisting method, which uses a hoisting device to conveniently and quickly realize the hoisting operation of the glass plate. The hoisting method includes the following specific steps:

[0057] Step 1: Perform deformation preview on the installation body 100.

[0058] Among them, the installation body 100 includes an upper beam body 101 and a lower beam body 102, and an installation space for installing the parts to be installed 200 is formed between the upper beam body 101 and the lower beam body 102 to ensure that the glass panels waiting for the installation parts 200 can be accurately and stably installed in the installation space. The upper beam body 101 is configured to install a bar device 300, and the position and height of the bar device 300 can be easily adjusted to adapt to different parts to be installed 200 and hoisting requirements. Among them, a hanging basket is hung on the bar device 300 to facilitate the installation construction of the workers on the hanging basket. It should be noted that the technical personnel in this field are clear about the specific structure and working principle of the bar device 300, which will not be repeated here.

[0059] Specifically, in step one, a counterweight with a mass equal to that of the component 200 to be installed is hung at the installation point of the lower beam body 102 to simulate the pressure exerted by the component 200 to be installed on the installation body 100 during the actual lifting process, and the sinking displacement of the installation point is measured according to a preset time, and then the bottom of the component 200 to be installed is pre-raised according to the sinking displacement, thereby compensating for the sinking caused by the deformation of the installation body 100 during the lifting process, thereby ensuring that the component 200 to be installed can be accurately and stably installed in the predetermined position.

[0060] Step 2: adjust the action of the driver 21 to adjust the pitch angle of the adsorption member 22 relative to the horizontal direction, and adsorb the component 200 to be installed onto the adsorption member 22 .

[0061] Step 3: The lifting mechanism 4 lifts the lifting frame 1 to a temporary height, and the counterweight driver is activated to adjust the gear state of the lifting frame 1 by sliding the counterweight assembly 31 relative to the mounting portion 11 .

[0062] Specifically, in step 3, the output end of the lifting mechanism 4 is provided with a plurality of slings 41, and the plurality of slings 41 are respectively connected to the lifting points of the lifting frame 1 in a one-to-one correspondence, so that the stability during the lifting process can be ensured. Even if one of the slings 41 has a problem or is subjected to uneven force, the other slings 41 can still continue to work, thereby maintaining the balance of the lifting frame 1.

[0063] Step 4: Lift the lifting frame 1 to the installation height through the lifting mechanism 4.

[0064] Step 5: temporarily fix the component 200 to be installed on the installation body 100 .

[0065] Specifically, in step five, one of the component 200 to be installed and the installation body 100 is provided with a fixing recess 201, and the other is provided with a fixing protrusion 103 that is snap-fitted with the fixing recess 201. The snap-fitting of the fixing protrusion 103 and the fixing recess 201 achieves preliminary fixation between the component 200 to be installed and the installation body 100, thereby ensuring that before subsequent fixed installation, the component 200 to be installed will not move or fall off due to external force.

[0066] More specifically, in this embodiment, the fixing recess 201 is provided on the member to be installed 200, and the fixing protrusion 103 is provided on the installation body 100, and the fixing recess 201 of the member to be installed 200 is sleeved on the fixing protrusion 103 of the installation body 100, so that the fixing recess 201 and the fixing protrusion 103 are mutually engaged. In other embodiments, the fixing recess 201 is provided on the installation body 100, and the fixing protrusion 103 is provided on the member to be installed 200, and again, the specific arrangement positions of the above components are not excessively limited.

[0067] Step 6: Fix the component 200 to be installed on the installation body 100 and release the stress.

[0068] It should be noted that the hoisting method provided in this embodiment: first, a deformation preview is performed on the installation body 100, and then the deformation of the installation body 100 during the hoisting process is predicted and evaluated, which helps to ensure the safety and accuracy of the hoisting operation and avoid problems caused by excessive deformation during the installation process. Then, by adjusting the action of the driver 21, the pitch angle of the adsorption member 22 relative to the horizontal direction is adjusted, and the part to be installed 200 is adsorbed on the adsorption member 22, so as to adapt to the vertical installation requirements of the glass plate waiting for the installation member 200 at different angles, so that the hoisting operation is more efficient and accurate, and the cumbersome manual operation is reduced. Then, the lifting frame 1 is lifted to a temporary height by the lifting mechanism 4, and the counterweight driver is activated, and the counterweight assembly 31 slides relative to the installation part 11 to adjust the gear state of the lifting frame 1 to ensure the balance and stability during the hoisting process. Then, the lifting frame 1 is lifted to the installation height by the lifting mechanism 4, and then the part to be installed 200 is temporarily fixed on the installation body 100, so as to ensure the stability and safety during the hoisting process, and provide a basis for subsequent fixed installation. Finally, the installation member 200 is fixedly installed on the installation body 100, and stress is released, thereby ensuring a firm connection and stability between the installation member 200 and the installation body 100. Through the above arrangement, the hoisting method of the present application can conveniently and quickly realize the hoisting operation of the glass plate.
