Description

Technical Field

[0001] This invention relates to the field of power maintenance technology, specifically to an adjustable, multifunctional power maintenance safety protection device. Background Technology

[0002] During power maintenance, operators need to move to the power equipment using appropriate equipment and then carry out effective maintenance by retrieving the maintenance tools they carry. For example, patent document CN107243143A discloses an adjustable multifunctional power maintenance safety protection device. This device uses a net structure to conveniently place maintenance tools, adding the functionality of a power maintenance safety protection device that cannot carry tools, thus solving the problem of incomplete functionality of power maintenance safety protection devices. The left and right connecting straps can easily fix the power maintenance safety protection device to the legs, preventing workers from slipping while working, thus solving the problem of poor protective effect of power maintenance safety protection devices. The climbing pole device makes it easy to climb utility poles, solving the problem of inconvenience for climbing utility poles with the power maintenance safety protection device. The support pole device allows workers to bend their legs and straighten them with the rebound force of the spring when climbing utility poles, while saving workers' energy. The rubber blocks prevent workers from slipping while climbing utility poles.

The outer walls of the movable column 3 and the bottom cylinder 2 are respectively rotatably provided with a first support rod 4 and a second support rod 5. The outer wall of the movable column 3 is provided with a movable rod 6.

The outer walls of the multiple transmission sprockets 7 are provided with a chain 8. The chain link end of the chain 8 is fixedly sleeved with a mounting plate 9. The outer wall of the mounting plate 9 is fixedly provided with a support plate 10. The outside of the support plate 10 is sleeved with a protective frame 11. A limiting telescopic rod 29 is fixed between the support plate 10 and the bottom plate 1. A motor 12 is fixedly installed at the lower back side of the bottom cylinder 2. The end of the output shaft of the motor 12 passes through the bottom cylinder 2 and is fixedly connected to the second support rod 5. An adjustment guide mechanism for adjusting the position of the moving rod 6 is provided between the moving rod 6 and the side of the bottom cylinder 2. The adjustment guide mechanism includes a positioning bolt 19. Two symmetrically arranged guide rods 20 are fixedly provided at the lower end of the outer wall of the bottom cylinder 2. A slider 21 is slidably sleeved on the rod wall of the guide rod 20. The slider 21 is fixedly connected to the moving rod 6. The moving rod 6 is L-shaped. The positioning bolt 19 is threaded inside the moving rod 6. A rotating block 22 is fixedly sleeved on the end of the positioning bolt 19. The outer wall of the bottom cylinder 2 has multiple spaced positioning holes 23 that cooperate with the positioning bolt 19. The guide rod 20 is a U-shaped guide rod.

[0019] In order to increase the scope of maintenance for operators and improve the protection of operators by the equipment, such as Figure 1 and Figure 4 As shown, a movable maintenance mechanism for adjusting the position of the protective frame 11 is provided between the support plate 10 and the protective frame 11. The movable maintenance mechanism includes an adjusting screw 24. A through hole is opened inside the support plate 10. The adjusting screw 24 is rotatably disposed in the through hole, and a movable plate 25 is threadedly sleeved on the rod wall. Both ends of the movable plate 25 are fixedly connected to the inner wall of the protective frame 11. A knob 26 is fixedly sleeved on the rod wall of the adjusting screw 24. A cavity is opened inside the support plate 10 near the movable column 3. The knob 26 is located in the cavity. Rotation holes 27 are opened on both the upper and lower sides of the cavity. The side of the knob 26 is rotatably disposed in the rotation hole 27.

[0020] In summary, this adjustable multi-functional power maintenance safety protection device can be easily moved to the required position for power maintenance by first using the casters 28 at the bottom of the base plate 1, providing a convenient position for subsequent maintenance operations. To adjust the maintenance height, first loosen the limiting bolt 18 on the crank handle 17 to disengage it from the threaded groove on the outer wall of the base cylinder 2, thus releasing the crank handle 17 from its fixation. Then, rotate the crank handle 17, which drives the crossbar 13 to rotate. The drive bevel gear 14 at one end of the crossbar 13 rotates accordingly. Since the drive bevel gear 14 meshes with the transmission bevel gear 16 on the wall of the drive screw 15, the transmission bevel gear 16 drives the drive screw 15 to rotate at the bottom of the inner wall of the base cylinder 2. Because the drive screw 15 is threadedly connected to the moving column 3, and both the moving column 3 and the base cylinder 2 have rectangular cross-sections, restricting the rotation of the moving column 3, the rotation of the drive screw 15 will drive the moving column 3 to slide up and down inside the base cylinder 2, thereby adjusting the height of the moving column 3 and thus adjusting the foundation support height of the entire device. After the height is adjusted appropriately, reverse the tightening of the limiting bolt 18 to re-insert it into the corresponding threaded groove, fix the crank handle 17, and maintain the stability of the height of the moving column 3. When the position of the support plate 10 needs to be adjusted to meet different maintenance requirements, the motor 12 at the lower back of the bottom cylinder 2 is started. The output shaft of the motor 12 drives the second support rod 5 to rotate, and the transmission sprocket 7 on the second support rod 5 rotates accordingly. Under the transmission action of the chain 8, the transmission sprockets 7 on the first support rod 4 and the moving rod 6 also rotate synchronously. The chain 8 drives the mounting plate 9 at the end of the chain link to move, and the mounting plate 9 in turn drives the support plate 10 to move. At the same time, the limiting telescopic rod 29 between the support plate 10 and the bottom plate 1 will extend and retract accordingly, thus controlling the movement of the support plate 10. It serves as a limit guide to ensure the stable movement of the support plate 10. At the same time, when adjusting the support height of the device, the position of the moving rod 6 can be adjusted to change the transmission state of the transmission sprocket 7. First, loosen the positioning bolt 19 so that its end is disengaged from the positioning hole 23 on the outer wall of the bottom cylinder 2. Then push the moving rod 6. The moving rod 6 drives the slider 21 to slide on the guide rod 20. After the moving rod 6 is adjusted to the appropriate position, tighten the positioning bolt 19 in the opposite direction so that it is inserted into the corresponding positioning hole 23 to fix the position of the moving rod 6 and ensure the stability of the transmission of the transmission sprocket 7. When an operator stands on the support plate 10 and needs to adjust the position horizontally to expand the maintenance range, they can rotate the knob 26 inside the cavity of the support plate 10. The knob 26 drives the adjusting screw 24 to rotate within the through hole of the support plate 10. Since the adjusting screw 24 is threadedly connected to the moving plate 25, and both ends of the moving plate 25 are fixedly connected to the inner wall of the protective frame 11, and the protective frame 11 is sleeved on the outside of the support plate 10, restricting the rotation of the moving plate 25, the rotation of the adjusting screw 24 will drive the moving plate 25 to move the protective frame 11 horizontally on the support plate 10. This allows for maintenance operations on electrical equipment within a wider range. At the same time, the protective frame 11 also provides safety protection for the operator, preventing the operator from falling during the movement.
