[0058] Further, refer to Figure 1 and Figure 2 The waterproof coiled material retention rack further includes a counterweight mechanism disposed on the frame 11 , the counterweight mechanism being connected to the drive shaft 16 , and the counterweight mechanism being used to balance the tension generated by the floating frame 14 and the waterproof coiled material on the floating frame 14 .

[0059] The counterweight mechanism includes a counterweight sprocket 51 , a counterweight chain 52 , a counterweight guide sprocket 53 and a counterweight box 54 .

[0060] There are two counterweight sprockets 51, two counterweight chains 52 and two counterweight guide sprockets 53, and each counterweight sprocket 51, two counterweight chains 52 and two counterweight guide sprockets 53 form a group. The counterweight sprocket 51 is installed and fixed on the drive shaft 16, and the mounting frame of the counterweight guide sprocket 53 is installed and fixed on the top of the mounting platform 111. The counterweight chain 52 is wound around the counterweight sprocket 51 and the counterweight guide sprocket 53. One end of the counterweight chain 52 is fixedly connected to the counterweight sprocket 51, and the other end of the counterweight chain 52 is fixedly connected to the top of the counterweight box 54.

[0062] When in use, when the floating frame 14 needs to rise, the power assembly 21 drives the ratchet 19 to rotate through the active sprocket 22 and the chain, the ratchet 19 drives the inner wheel 17 and the drive shaft 16 to rotate through the pawl 18, and the drive shaft 16 drives the floating frame 14 to rise on the frame 11 through the lifting mechanism;

[0063] When the floating frame 14 needs to be lowered, the power assembly 21 reverses, and then the power assembly 21 drives the ratchet 19 to rotate through the active sprocket 22 and the chain. During the rotation of the ratchet 19, it does not mesh with the pawl 18 and does not provide abutment force to the pawl 18. If the gravity of the floating frame 14 is greater than the sum of the tension of the waterproof coiled material and the gravity of the counterweight mechanism, the floating frame 14 drives the driving shaft 16 to reverse, and then the floating frame 14 descends;

[0064] When the floating frame 14 needs to float, the motor has no power. When the sum of the tension of the waterproof coiled material on the floating frame 14 and the gravity of the counterweight mechanism changes up and down with the gravity of the floating frame 14, the floating frame 14 floats up and down on the frame 11. If the floating frame 14 rises and touches the upper limit switch, the motor is started to reverse and the motor drives the floating frame 14 to descend; if the floating frame 14 descends and touches the lower limit switch, the motor is started to rotate forward and the motor drives the floating frame 14 to rise.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
