Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5As shown, this utility model provides a technical solution: a lightweight building material lifting and transporting device to prevent falls, including a base plate 1, a support frame 101, a connecting seat 103, a support column 104, a hanging column 105, a winch 106, and a wire rope 2. Four sets of support frames 101 are fixedly installed on the outer wall of the base plate 1. The connecting seat 103 is fixedly connected to the upper wall of the base plate 1. The support column 104 is fixedly connected to the upper end of the connecting seat 103. The winch 106 is installed at the left end of the support column 104. The hanging column 105 is connected to the right end of the support column 104. The wire rope 2 is installed at the lower end of the hanging column 105. The left end of the wire rope 2 is connected to the winch 106.

[0025] A slider 201 is installed at the lower end of the lifting column 105. A steel wire rope 2 passes through the inside of the slider 201. A protective shell 202 is provided at the lower end of the slider 201. A flywheel 205 is provided inside the protective shell 202. A first ratchet 203 and a second ratchet 204 are respectively provided on both sides of the flywheel 205. The first ratchet 203 and the second ratchet 204 are fixedly installed inside the protective shell 202. A first rotating shaft 207 is provided at the center of the flywheel 205. The two ends of the first rotating shaft 207 are engaged in grooves opened in the outer wall of the protective shell 202. The two walls of the flywheel 205 are respectively A connecting block 208 is provided. Both ends of the two sets of connecting blocks 208 have openings, and the upper opening is connected to the magnet 302 by a fixing screw 209. A second hook 301 is provided at the lower opening of the connecting block 208. The lower end of the second hook 301 is connected to the flywheel 205 by a fixing screw 209. Magnets 302 are respectively provided on the outer walls of the second hook 301 and the first hook 3. Fixing blocks 303 are provided on both walls of the flywheel 205. One end of the fixing block 303 is connected to a telescopic spring 304, and the telescopic spring 304 is connected to the second hook 301.

[0026] Based on the overall structure of the device, the simple structure is used to achieve the function of preventing falls, which can significantly reduce the risk of building materials suddenly falling during the lifting process. At the same time, the addition of an anti-disengagement structure to the hook 306 makes it more stable after the transport device is attached. This not only protects the safety of construction personnel and equipment below, but also reduces potential injuries and losses caused by falling building materials.

[0027] like Figure 1 As shown, multiple sets of counterweights 102 are stacked on the upper wall of the base plate 1.

[0028] By stacking multiple sets of counterweights 102 on the upper wall of the base plate 1, the overall device can be made more stable during the lifting and transportation process.

[0029] like Figure 1 As shown, the upper and lower walls of the protective shell 202 are provided with slots and holes and steel wire ropes 2 are installed in the slots. The upper end of the steel wire rope 2 is connected to a slider 201 and the lower end of the steel wire rope 2 is connected to a connector 305.

[0030] By opening slots in the upper and lower walls of the protective shell 202, the wire rope 2 can pass through the slots and be wound around the slot 206.

[0031] like Figure 2 As shown, the flywheel 205 has a slot 206 on its outer wall. The slot 206 has a spiral curve shape, and a steel wire rope 2 is wound inside the slot 206.

[0032] By making the routing shape of the slot 206 a spiral curve, when the wire rope 2 is wound around the slot 206, the tension of the wire rope 2 can drive the flywheel 205 to rotate.

[0033] like Figure 5 As shown, the lower end of the connector 305 is connected to a hook 306. The outer wall of the hook 306 has a slot and a second rotating shaft 307 is installed in the slot. A torsion spring 308 is sleeved on the outside of the second rotating shaft 307.

[0034] By opening a slot inside the hook 306 and installing a second rotating shaft 307 inside the slot, the second rotating shaft 307 can drive the outer baffle 309 to rotate.

[0035] like Figure 5 As shown, baffles 309 are fitted at both ends of the second rotating shaft 307, one end of the torsion spring 308 is connected to the inner wall of the hook 306, and the other end of the torsion spring 308 is connected to the baffle 309.

[0036] By installing a torsion spring 308 on the outside of the second rotating shaft 307, and connecting one end of the torsion spring 308 to the inner wall of the hook 306 and the other end to the baffle 309, the baffle 309 can be automatically returned to its original position by the elastic force of the torsion spring 308.

[0037] Working Principle: This device can lift and transport lightweight building materials and has an anti-fall function. After the device is assembled and debugged, a counterweight 102 can be added to the upper wall of the base plate 1 to increase the counterweight, making the overall device more stable when lifting building materials. At the same time, the winch 106 can stretch and loosen the wire rope 2 to adjust the height when transporting building materials. The slider 201, in conjunction with the relevant equipment at the lower end of the hanging column 105, can achieve movement. The above is the existing technology, and its detailed working principle will not be described in detail here. When it is necessary to transport and lift building materials, the building materials generally need to be tied up, and then the hook 306 is used to hang them on the tied wire rope. When the baffle 309 is pressed inward, the wire rope can be extended into the inside of the hook 306. When the torsion spring 308 is compressed, when the baffle 309 is released, the baffle 309 will be elastically returned to its original position by the torsion spring 308. After it is hung, the winch 106 will pull the wire rope 2, which will drive the flywheel 205 to rotate slowly. When the winch 106 malfunctions and the wire rope 2 is not stretched tightly, the building materials being lifted and transported will fall rapidly. At this time, the wire rope 2 will drive the flywheel 205 to rotate rapidly. The first hook 3 and the second hook 301 will be rotated by the centrifugal force of rotation and engage with the buckle on the first ratchet 203 or the second ratchet 204, so that the flywheel 205 is fixed with the first ratchet 203 and the second ratchet 204, so that the flywheel 205 will no longer rotate, and at the same time, the building materials being lifted and transported at the lower end will be prevented from continuing to fall.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
