Description

Technical Field

[0001] The utility model belongs to the technical field of lifting equipment, and more specifically, particularly relates to a hook type pulley structure. Background Art

[0002] Lifting block is a simple lifting machine that lifts heavy objects vertically through a sprocket or drum. It is light in weight, compact in structure, easy to use, and suitable for simple lifting work in construction. Lifting blocks can be divided into single-door blocks, double-door blocks, and multi-door blocks according to the number of wheels. According to the connection method between the block and the hoisted object, it can be divided into four types: hook block, chain ring block, ring block, and hanger block.

[0003] After searching, the patent disclosure is CN219296943U, which discloses a pulley structure including a pulley device and a wire rope group. By connecting with a first wire rope and a third wire rope, the length of the wire rope group is extended, so that the wire rope group can connect the pulley device and the object.

[0004] It can be seen from the above-mentioned patent that the pulley structure is generally set as a single-arm single-roller. The rope will be subjected to great force during the stretching process, and will break after long-term use. In addition, there is no hook at the upper end, so it is inconvenient to install and fix. Therefore, a hook-type pulley structure is designed to solve the above problems. Utility Model Content

[0012] The utility model provides a hook type pulley structure, which has the following beneficial effects:

[0013] 1. In the hook-type pulley structure, the rotating ring causes a certain angle change between the first mounting frame and the second mounting frame, so that a certain distance is presented between the first pulley and the second pulley, thereby changing the tension of the subsequent rope. By increasing the distance, the tension can be reduced and the damage to the rope can be reduced.

At the same time, a second pulley 11 is rotatably installed on the bottom of the second mounting frame 10. At this time, a complete structure is formed, which can be used as the first section of the pulley structure.

[0022] In this embodiment, please refer to Figure 1 A swivel 2 is rotatably installed on the side of the cylindrical ring 1, and is fixedly connected to a first mounting frame 3 through the swivel 2. A first pulley 6 is rotatably installed at the end of the first mounting frame 3. This is the second section of the pulley structure. The different angles of the first pulley 6 and the second pulley 11 can change the force on the installation rope.

[0023] In this embodiment, please refer to Figure 1 and Figure 2 The side surface of the second mounting frame 10 is fixedly connected to one side of the connecting hinge 4, and the other side of the connecting hinge 4 is fixedly connected to the threaded rod 7. At this time, the threaded rod 7 can be rotated at different angles.

[0024] In this embodiment, please refer to Figure 1 A slide groove 5 is provided on the side surface of the first mounting frame 3, so that the threaded rod 7 can pass through the slide groove 5, and a round nut 12 and a first fixing nut 8 are installed on the surface of the threaded rod 7. The round nut 12 and the first fixing nut 8 can be used to fix the threaded rod 7 and the first mounting frame 3, thereby ensuring that a certain angle is formed between the first mounting frame 3 and the second mounting frame 10, so that the distance between the first pulley 6 and the second pulley 11 is constant.

[0025] In this embodiment, please refer to Figure 3 , a threaded nail 13 is installed inside the cylindrical ring 1, and a connecting rod 14 is fixedly installed on the side surface of the threaded nail 13. The threaded nail 13 and the cylindrical ring 1 are fixedly installed by a second fixing nut 15. When the angles of the first mounting frame 3 and the second mounting frame 10 are determined, the symmetry line of the first mounting frame 3 and the second mounting frame 10 is located on the vertical line, and then the second fixing nut 15 is tightened.

[0026] In this embodiment, please refer to Figure 4 A hook 16 is fixedly installed on the side surface of the connecting rod 14, and a hook 17 is rotatably installed on the end of the hook 16. The hook 17 is rotated so that the hook 16 can be hung on the column to be installed, and then the hook 17 is rotated again, so that the hook 16 and the hook 17 form a closed loop to ensure the installation effect.

By increasing the distance, the tension can be reduced, and then the round nut 12 and the first fixing nut 8 are rotated to fix the threaded rod 7 and the first mounting frame 3. During installation, the symmetry line of the first mounting frame 3 and the second mounting frame 10 is in a vertical state, and then the second fixing nut 15 is used to lock the threaded nail 13, so that the connecting rod 14 can be fixed. At this time, the hook 16 on the side of the connecting rod 14 is also in a vertical line, which is convenient for subsequent use.

[0030] The end of the hook 16 is rotatably connected to the hook 17. The hook 17 is rotated so that the hook 16 can be hung on the column to be installed, and then the hook 17 is rotated again, so that the hook 16 and the hook 17 form a closed loop, and then the clamping rod 19 is clamped in the clamping groove 20 on the side of the hook 17, so that the hook 17 is fixed to prevent the hook 17 from moving, thereby ensuring the stability of the installation and fixation, and can effectively reduce the possibility of falling during installation and reduce the occurrence of danger.
