Technical Field

[0001] This utility model relates to the field of power equipment installation technology, and in particular to a quick-tightening device for power equipment foundation bolts. Background Technology

[0002] A quick-tightening device for foundation bolts of power equipment is a tool or device used in the installation and maintenance of power equipment to quickly and efficiently tighten foundation bolts to a specified torque or position.

[0003] When installing electrical equipment, after the bolts are installed, they often need to be tightened with relevant quick-tightening equipment to ensure their tightness and stability, so as to prevent the equipment from being damaged due to the bolts falling off during subsequent use. However, when tightening bolts with existing equipment, the staff needs to change to different diameter equipment according to different bolt models, which is inconvenient when selecting and replacing equipment.

[0004] Therefore, a quick-tightening device for foundation bolts of power equipment is proposed to address the above situation. Utility Model Content

Guide metal blocks are slidably installed in multiple guide openings, and adaptation metal blocks are fixedly installed on one side of each of the multiple guide metal blocks, so as to facilitate the movement of the corresponding adaptation metal blocks by the multiple guide metal blocks.

[0013] Specifically, a worm gear is rotatably mounted on the top inner wall of the fastening housing, and a worm is rotatably mounted on one side inner wall of the fastening housing. The worm meshes with the worm gear, and a knob is fixedly mounted on the other end of the worm, which can be used by the operator to adjust the worm.

[0014] Specifically, a flat threaded disc is fixedly installed at the bottom of the worm gear, which can drive the flat threaded disc to rotate.

[0023] Reference Figure 1-5 A quick-tightening device for foundation bolts of power equipment includes a fastening sleeve 1 for installing foundation bolts of power equipment. A threaded sleeve 3 is fixedly installed at the bottom of the fastening sleeve 1. A transmission mechanism is provided on the inner side of the fastening sleeve 1. A fastening housing 8 is provided at the bottom of the transmission mechanism. An adaptation mechanism is provided on the inner side of the fastening housing 8. The adaptation mechanism is used to clamp the bolt.

[0024] In this embodiment, two handles 2 are fixedly installed on the outer side of the fastening sleeve 1 to facilitate the staff to hold the equipment.

[0025] In this embodiment, a notched ring 4 is fixedly installed at the bottom end of the threaded sleeve 3, which facilitates the adjustment of the worm gear 10 by the operator through the notch.

[0026] In this embodiment, the transmission mechanism includes a threaded rod 7 and a hexagonal column 6. The threaded rod 7 is threadedly connected to the inner side of the threaded sleeve 3. The hexagonal column 6 is rotatably installed on the top inner wall of the fastening sleeve 1. The top of the threaded rod 7 is provided with a hexagonal groove. The hexagonal column 6 is adapted to the hexagonal groove, and the threaded rod 7 can be rotated by the hexagonal column 6.

[0027] In this embodiment, a motor slot is provided on the top inner wall of the fastening sleeve 1, and a servo motor 5 is fixedly installed on one side inner wall of the motor slot. The output shaft of the servo motor 5 is fixedly connected to the hexagonal column 6, and the hexagonal column 6 can be rotated by the servo motor 5.

[0028] In this embodiment, multiple guide openings 15 are provided on the outer side of the fastening housing 8.

[0029] In this embodiment, the adaptation mechanism includes multiple guide metal blocks 14 and multiple adaptation metal blocks 16. Guide metal blocks 14 are slidably installed in multiple guide ports 15, and adaptation metal blocks 16 are fixedly installed on one side of each of the multiple guide metal blocks 14, so that the corresponding adaptation metal blocks 16 can be moved by the multiple guide metal blocks 14.

[0030] In this embodiment, a worm gear 9 is rotatably mounted on the top inner wall of the fastening housing 8, and a worm 10 is rotatably mounted on one side inner wall of the fastening housing 8. The worm 10 meshes with the worm gear 9, and a knob 11 is fixedly mounted on the other end of the worm 10. The operator can adjust the worm 10 by using the knob 11.

[0031] In this embodiment, a flat threaded disk 12 is fixedly installed at the bottom of the worm gear 9, and the flat threaded disk 12 can be rotated by the worm gear 9.

[0032] In this embodiment, racks 13 are fixedly installed on the top of multiple guide metal blocks 14, and multiple racks 13 are adapted to the same planar threaded disk 12, so that multiple racks 13 can be moved by the planar threaded disk 12.

[0033] Working principle: In use, the operator first attaches the adapting mechanism to the bolt, then manually rotates knob 11. Rotation of knob 11 drives worm gear 10 to rotate, which in turn drives worm wheel 9 to rotate. Worm wheel 9 drives flat threaded disc 12 to rotate, which in turn drives multiple racks 13 to move. The movement of racks 13 then moves corresponding guide metal blocks 14. These guide metal blocks 14 are slidably installed in corresponding guide openings 15, thus restricting their movement; they can only move back and forth. The movement of guide metal blocks 14 drives the corresponding adapting metal blocks 16 to move. 6. The same bolt is clamped by the movement, and then the servo motor 5 is started. The servo motor 5 drives the hexagonal column 6 to rotate, and the rotation of the hexagonal column 6 drives the threaded rod 7 to rotate. The bottom end of the fastening sleeve 1 is fixedly installed with the threaded sleeve 3. The operator holds the two handles 2 to stabilize the fastening sleeve 1, so the threaded sleeve 3 cannot rotate. The threaded rod 7 is threadedly connected to the threaded sleeve 3. The threaded rod 7 moves upward and rotates upward, thereby driving the bolt to move upward into the fastening sleeve 1. Then, the exposed end of the bolt is aligned with the mounting hole of the power equipment. Then, the servo motor 5 is started to reverse, thereby screwing the bolt into the mounting hole and tightening it.

[0034] The technological advancements of this invention compared to existing technologies are: it can adapt to bolts of different sizes and diameters, eliminating the need for frequent tool changes and greatly improving bolt tightening efficiency; at the same time, the notched ring 4 at the bottom of the threaded sleeve 3 can contact the electrical equipment, thereby enabling more stable bolt tightening and increasing the practicality of the equipment.
