Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0027] A cargo lifting device is characterized by comprising a mounting plate 1, wherein mounting holes are provided at the corners of the mounting plate 1, and fixing bolts (not shown in the figure) pass through the mounting holes to be fixed to a crossbeam or a lifting frame, thereby enabling installation in different positions according to the construction environment and providing strong flexibility; a mounting frame 2 is installed on one side of the mounting plate 1, and a spool 3 is rotatably mounted inside the mounting frame 2, with a lifting rope 5 wound on the spool 3, and a plurality of hooks 6 installed at the end of the lifting rope 5. The arrangement of the plurality of hooks 6 provides strong stability when lifting or hoisting cargo, preventing cargo from tilting or falling due to a shift in the center of gravity, thus eliminating safety hazards;

[0028] In detail: The mounting frame 2 includes a mounting ring 201 and a fixing ring 202, which are arranged parallel to each other. Several parallel support rods 204 are fixed at equal intervals along the circumferential direction between the mounting ring 201 and the fixing ring 202. The support rods 204 serve to fix the mounting ring 201 and the fixing ring 202. Several mounting seats 205 are integrally formed on the circumferential surface of the mounting ring 201. Fixing bolts (not shown in the figure) pass through the mounting seats 205 and are threaded onto the mounting plate 1, thereby fastening the mounting frame 2 and preventing the mounting frame 2 from shaking or loosening during use. A support ring 203 is provided at the axis of the fixing ring 202, and several support rods 204 are also fixed at equal intervals along the circumferential direction between the fixing ring 202 and the support ring 203. The support rods 204 serve to fasten the fixing ring 202 and the support rods 204.

[0029] It should be noted that a protective shell 7 is also installed on the side of the mounting plate 1, and both the mounting frame 2 and the cable reel 3 are located inside the protective shell 7. The protective shell 7 serves to protect the cable reel 3. On the one hand, it prevents external objects from entering the interior of the mounting frame 2 and damaging the cable reel 3. On the other hand, it prevents workers' hands from accidentally entering the mounting frame 2 and coming into contact with the cable reel 3, causing injury to the workers and increasing safety hazards. In detail, a number of mounting holes 8 are equally spaced along the circumference on the side and circumferential surface of the protective shell 7. Fixing bolts pass through the mounting holes and connect to the first threaded hole on the support rod 204. The mounting frame 2 and the protective shell 7 are connected by threads, which allows the protective shell 7 to be disassembled. When the lifting device is not in use, it is convenient to maintain or repair the internal structural components of the protective shell 7.

[0030] A drive shaft 301 is fixed at the center of the spool 3. One end of the drive shaft 301 passes through the spool 3 and is rotatably mounted inside the mounting plate 1. The other end of the drive shaft 301 passes through the spool 3 and is rotatably mounted inside the support ring 203. It should be noted that bearings are provided at the connection between the drive shaft 301 and the mounting plate 1 and at the connection between the drive shaft 301 and the support ring 203. The bearings allow the spool 3 to rotate smoothly inside the mounting frame 2 without jamming.

[0031] The mounting frame 2 is externally mounted with a drive structure 4, which is connected to one end of the drive shaft 301. The drive structure 4 drives the reel 3 to rotate, thereby lifting or lowering the goods. It should be noted that the drive structure 4 has two different structures: electric drive and manual drive, which can be selected according to the construction environment.

[0032] The first type of drive structure 4 includes a first mounting plate 41a located on one side of the support ring 203, a drive motor 42a mounted on one side of the first mounting plate 41a, the drive motor 42a being a servo motor, and a first pin 43a fixed to the output shaft of the drive motor 42a. It should be noted that the first pin 43a is not cylindrical, but can be polygonal or elliptical. The first pin 43a extends through the first mounting plate 41a into the drive groove 302 opened at the end of the drive shaft 301.

[0033] When the drive motor 42a drives the first pin 43a, the first pin 43a can drive the drive shaft 301 to rotate, which in turn drives the reel 3 to rotate. The reel 3 can then unload or release the line, thereby enabling the lifting or lowering of goods.

[0034] The second driving method 4: Driving method 4 includes a second mounting plate 41b located on one side of the support ring 203. A first rotating shaft 42b is rotatably mounted at the center of the second mounting plate 41b. It should be noted that a bearing is also provided between the first rotating shaft 42b and the second mounting plate 41b. Through the bearing, the first rotating shaft 42b can rotate smoothly inside the second mounting plate 41b. A second pin 43b is fixed to one end of the first rotating shaft 42b. The second pin 43b is non-cylindrical and can be polygonal or elliptical. One end of the second pin 43b is inserted into the drive groove 302. A rotating arm 44b is fixed to the other end of the first rotating shaft 42b. A rotating handle 45b is fixed to one end of the rotating arm 44b. A rotating handle 46b is rotatably mounted on the rotating handle 45b.

[0035] When the handle 45b is turned, the rotating arm 44b is rotated, which in turn drives the first rotating shaft 42b to rotate. The first rotating shaft 42b drives the drive shaft 301 to rotate through the second pin 43b, which in turn drives the reel 3 to rotate. This allows the reel 3 to perform the work of feeding or unloading wire, thereby enabling the lifting or lowering of goods.

[0036] It should be noted that the support ring 203 is connected to the first mounting plate 41a and the second mounting plate 41b in the same way. For ease of description, this application only describes the connection between the second mounting plate 41b and the support ring 203.

[0037] A number of arc-shaped guide plates 206 are fixed at equal intervals along the circumference on one side of the support ring 203; an arc-shaped guide groove corresponding to the arc-shaped guide plate 206 is provided on one side of the second mounting plate 41b. The arc-shaped guide plate 206 and the arc-shaped guide groove facilitate alignment during the installation of the second mounting plate 41b; a number of second threaded holes are provided on the arc-shaped guide plate 206, and through holes corresponding to the second threaded holes are provided on the arc-shaped guide groove. When the arc-shaped guide groove on one side of the second mounting plate 41b is inserted into the interior of the arc-shaped guide plate 206, the fixing bolt passes through the through hole and is threadedly connected to the second threaded hole, thereby fastening the first mounting plate 41a; thus, the first mounting plate 41a or the second mounting plate 41b can be replaced, and the drive structure 4 can be replaced according to the user's needs.

[0038] A rotating sleeve 9 is fixed on the inner wall of the protective shell 7, and a second rotating shaft 10 is rotatably installed inside the rotating sleeve 9. One end of the second rotating shaft 10 extends to the rotating component 11, and a ratchet 12 is fixed on one end of the rotating component 11. Ratchets 13 that cooperate with the ratchet 12 are fixed at equal intervals along the circumferential direction on the coil 3. When the goods are lifted, the ratchet 12 and the ratchet 13 are in a meshing state, thereby playing a locking role and preventing the goods from falling downward due to their own gravity due to the failure of the drive structure 4, thereby increasing the safety hazard.
