Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a highly safe block hoisting tool, including:

[0023] The base 1 has anti-slip textures on its lower end surface, which increases the friction between the base 1 and the ground and improves the stability of the device. A protective frame 2 is installed on the base 1, and multiple protective nets 3 are installed on the protective frame 2. A hoisting assembly is installed on the protective frame 2. Four mounting slots are opened on the upper end surface of the base 1. Four connecting blocks 4 are fixedly connected to the lower end surface of the protective frame 2. The fixing assembly includes four sliding slots opened on the side wall of the mounting slots respectively. A fixing block 5 is slidably connected in each of the four sliding slots. Two rotating cavities 6 are opened on the base 1, and two threaded rods 7 rotate through the base 1.

[0024] Two threaded rods 7 rotate within two rotating cavities 6 respectively. Four fixing blocks 5 are threadedly connected to the two threaded rods 7 respectively. A first bevel gear 8 is fixedly connected to the side wall of each of the two threaded rods 7. A second bevel gear 9 is rotatably connected to the inner wall of each of the two rotating cavities 6. The two first bevel gears 8 and the two second bevel gears 9 mesh with each other respectively. Two rotating rods rotatably pass through the side wall of the base 1. The two rotating rods are fixedly connected to the two second bevel gears 9 respectively. Each of the four connecting blocks 4 has a fixing opening. The fixing opening matches the shape of the fixing block 5. A handle 16 is fixedly connected to the rotating rod. The handle 16 is provided with an anti-slip pad. The anti-slip pad is made of rubber, which makes it easy for the user to rotate the rotating rod and improves the portability of the device.

[0025] The hoisting assembly includes two sets of round steel rods 10 fixedly connected to the side walls of the protective frame 2. The two ends of each round steel rod 10 are ring-shaped. Support rods 11 are installed on each of the two sets of round steel rods 10. Limiting components are installed on both support rods 11. Each limiting component includes two lifting slots opened on the support rods 11. Springs 12 are fixedly connected to the inner walls of both lifting slots. Limiting rods 13 are fixedly connected to the springs 12. The limiting rods 13 slide within the lifting slots. Two limiting grooves are opened on the inner walls of the lifting slots. Two limiting blocks are fixedly connected to the side wall of the limiting rod 13. The two limiting blocks slide in the two limiting grooves respectively to limit the limiting rod 13, preventing the limiting rod 13 from sliding out of the lifting groove and preventing the steel cable from falling off. Two fixing blocks 14 are installed on each round steel rod 10. Multiple bolts 15 are threaded through the fixing blocks 14. The multiple bolts 15 are threaded to the protective frame 2, which improves the bearing capacity of the round steel rod 10 and realizes secondary connection protection for the round steel rod 10.

[0026] The detailed working process of this utility model is as follows:

[0027] First, the user places the base 1 in the designated position, then stacks the blocks on the base 1. After stacking the required number of blocks, the user uses the appropriate lifting device to slowly lower the protective frame 2. Then, the staff adjusts the protective frame 2 so that the connecting block 4 aligns with the mounting slot. The connecting block 4 then moves into the mounting slot. At this point, the user rotates the handle 16, causing the second bevel gear 9 to rotate. The first bevel gear 8, located in the rotating cavity 6, begins to rotate, and the threaded rod 7 begins to rotate. The fixing block 5, located in the sliding groove, slides into the fixing opening, thus fixing the protective frame 2. This device can prevent blocks from loosening and falling during hoisting, thus avoiding injury. It is convenient and quick, improving the efficiency and safety of block hoisting. The user then passes the support rod 11 through the ring on the round steel hoist 10. Since the limiting rod 13 on the support rod 11 can retract, it will not affect the support rod 11 passing through the round steel hoist 10. Then, the hoisting wire rope is looped around both ends of the support rod 11. The limiting rods 13 at both ends of the support rod 11 are pushed up by the spring 12 to prevent the hoisting wire rope from falling off the support rod 11. The device is simple to operate, easy to use, install and disassemble, quick and cost-effective, highly safe and practical.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
