Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1-4A special lifting tool for the front support of an excavator boom includes a rectangular support frame 1, a first rectangular inner groove 2 is provided at the lower end of the rectangular support frame 1, and a lifting ring 14 is fixedly connected to the upper end of the rectangular support frame 1 for connecting with the front support part of the excavator boom. The system also includes a lifting device assembly, which includes a motor 3 mounted on the right side of a rectangular support frame 1. The motor 3 is a motor with a changeable rotation direction. A protective cover 15 is fixedly connected to the right side of the rectangular support frame 1, and the motor 3 is located inside the protective cover 15, which protects the motor 3. A bidirectional threaded rod 4 is rotatably connected between the left and right inner walls of the first rectangular inner groove 2. The two threaded ends of the bidirectional threaded rod 4 have opposite thread directions. The right end of the bidirectional threaded rod 4 penetrates the right inner wall of the first rectangular inner groove 2 and is fixedly connected to the output shaft of the motor 3. Both threaded ends of the bidirectional threaded rod 4... The slide block 5 is threadedly connected. A guide rod 13 is fixedly connected between the inner walls of the left and right sides of the first rectangular inner groove 2. The guide rod 13 passes through the two slide blocks 5 and is slidably connected to the two slide blocks 5. T-shaped inner grooves 6 are opened on the opposite sides of the two slide blocks 5. T-shaped inserts 7 are set in the two T-shaped inner grooves 6. The two T-shaped inserts 7 are slidably connected to the inner wall of the corresponding T-shaped inner groove 6. The lower end of the two T-shaped inserts 7 is rotatably equipped with hooks 8 for lifting objects. The two hooks 8 are moved by the control motor 3 to meet the lifting needs of objects of different specifications and sizes. The system also includes multiple limiting components, including a second rectangular inner groove 9 formed on the inner wall of the T-shaped inner groove 6. A limiting block 10 that can slide back and forth is provided in the second rectangular inner groove 9. The limiting block 10 fits against the T-shaped insert 7 and, together with the T-shaped inner groove 6, can stably limit the T-shaped insert 7. A first threaded rod 11 is rotatably connected to one side of the limiting block 10. The other end of the first threaded rod 11 passes through the inner wall of the second rectangular inner groove 9 and is fixedly connected to a torsion block 12. The first threaded rod 11 is threadedly connected to the slider 5. By rotating the torsion block 12, the limiting block 10 is moved into the second rectangular inner groove 9, which can release the limitation on the T-shaped insert 7 so that the hook 8 can be maintained and replaced.

[0015] In this utility model, during use, the entire device is first connected to the excavator via the lifting ring 14. Then, according to the specifications and dimensions of the object to be lifted, the motor 3 is started to drive the bidirectional threaded rod 4 to rotate, which drives the two sliders 5, the two T-shaped inserts 7, and the two hooks 8 to move synchronously towards or away from each other, so as to adjust the distance between the two hooks 8, thereby meeting the lifting requirements of objects of different specifications and dimensions. After the two hooks 8 are adjusted to the appropriate position, the two hooks 8 are connected to the object to be lifted. Finally, the front support of the excavator boom is controlled to drive the entire lifting device to rise, thus realizing the lifting operation of the object. When maintenance or replacement of hook 8 is required, first maintain hook 8 on the left side. Rotate the two torsion blocks 12 on the left side in sequence, causing the corresponding first threaded rod 11 to rotate, so that the two limiting blocks 10 on the left side move completely into the corresponding second rectangular inner groove 9. This releases the two limiting blocks 10 from limiting the T-shaped insert 7 on the left side. At this time, the T-shaped insert 7 can be removed from the T-shaped inner groove 6 to disassemble hook 8. After disassembly, take out the new T-shaped insert 7 and hook 8, and reinsert the T-shaped insert 7 into the T-shaped inner groove 6. Finally, rotate the two torsion blocks 12 in the opposite direction so that the two limiting blocks 10 on the left side re-fit with the T-shaped insert 7, thereby limiting and fixing the T-shaped insert 7 and hook 8, thus realizing the maintenance and replacement of hook 8. Similarly, referring to the above operation, hook 8 on the right side can be maintained and replaced. The whole maintenance process is relatively convenient, greatly reducing the actual maintenance workload and ensuring work efficiency. It should be noted that the wiring of motor 3 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control, power supply method and wiring layout of motor 3 will not be explained in detail.
