Description

Technical Field

[0001] The invention relates to the field of line towers, in particular to a high-voltage transmission line tower. Background Art

[0002] Line towers are tower-shaped buildings used for power transmission, mainly used to support transmission and distribution lines. Various tower types are space truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. The rods are connected by rough bolts, which are connected by shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual parts such as tower feet are welded from several steel plates into an assembly. Foot nails are set on one of the main materials of the tower to facilitate construction workers to climb the tower.

[0003] The line tower is outdoors for a long time. In order to facilitate maintenance, a ladder is also provided along the length of the tower body for operators to support and step on, so as to facilitate climbing to the top of the tower to maintain the power equipment. The existing Chinese public patent document: CN105735723B discloses a power transmission tower. By unlocking the positioning component, the moving rod is moved along the moving trajectory away from the tower body. At this time, the linkage component drives the corresponding pedal rod to move out of the opening. When the moving rod is located away from the tower body and fits with the support part again, all the pedal rods are They are all arranged perpendicularly to the moving rod, and the pedal rod and the ladder are located on the same side, which is convenient for the operator to climb up the ladder along all the pedal rods. However, when releasing the pedal rod, the moving rod that is installed and supports the pedal rod needs to be moved away from the supporting part of the tower body, and the plug block is relied upon to provide support for the gap between the moving rod and the supporting part. Since the moving rod is large in size and in an inclined state, the center of gravity of the moving rod will shift as the staff climbs, which may easily cause the plug block of the moving rod to be inserted back into the slot, causing the pedal rod to be retracted to the inner side of the moving rod, which poses a great safety hazard.

The outer side of the rotating rod 6 is rotatably installed on the inner side of the positioning shaft seat 23 to improve the stability of the rotation of the rotating rod 6.

[0032] The staff can rotate the rotating rod 6 so that the external thread on the outer side of the rotating rod 6 drives the sleeves 8 on the multiple moving cylinders 7 to move along the outer side of the positioning rod 9, thereby realizing the upward movement of the moving cylinder 7. The moving cylinder 7 drives the rack plate 14 to move synchronously along the slide groove on the inner side of the support plate 4 through the U-shaped frame 13, so that the rack plate 14 drives the gear 12 to rotate, and the gear 12 drives the pedal rod 5 to flip from the inside of the storage groove of the support plate 4 to the outside through the mounting rod 11, so that the pedal rod 5 and the support plate 4 are 90 degrees apart. The staff can climb through the multiple pedal rods 5 and can recycle the pedal rod 5 after the climbing operation is completed. The rotating rod 6 is used to drive the pedal rod 5 to open, without the need to displace the support plate 4, thereby solving the problem of the pedal rod 5 being easily retracted during climbing, thereby achieving the effect of facilitating climbing and storing protection.

[0033] The support rod mechanism includes a limit plate 15 arranged at the bottom of the moving cylinder 7, and the surface of the limit plate 15 is provided with a through hole for the positioning rod 9 and the rotating rod 6 to pass through. A plurality of positioning frames 16 are fixedly installed between the top of the limit plate 15 and the outer side of the moving cylinder 7 and are symmetrically distributed in the center. A support bar 17 is fixedly installed at one end of the pedal rod 5 close to the mounting rod 11, so that when the pedal rod 5 rotates outward, it can drive the support bar 17 to contact the bottom of the limit plate 15 to provide auxiliary support for the pedal rod 5. The inner side of the support plate 4 is provided with a storage groove 2 for the support bar 17 to limit the sliding of the support bar 17. A triangular plug block 18 is fixedly installed at one end of the support bar 17 away from the pedal rod 5. The surface of the limit plate 15 is provided with a triangular plug block 18 for limiting the insertion The insertion cavity has a width greater than that of the triangular plug block 18, which is convenient for the triangular plug block 18 to be inserted into the insertion cavity. A mounting strip 19 is provided on the outer side of the limiting plate 15. Two symmetrically distributed plug rods 20 are fixedly installed on the outer side of the mounting strip 19. A sliding hole for the plug rods 20 to be limited and inserted is provided on the outer side of the limiting plate 15. An arc-shaped push-off strip 21 located on the inner side of the insertion cavity is fixedly installed between the two plug rods 20. Two symmetrically distributed springs 22 are fixedly installed between the mounting strip 19 and the limiting plate 15. A plurality of arc-shaped grooves for the arc-shaped push-off strips 21 to be limited and inserted are provided on the outer side of the triangular plug block 18. The elasticity of the springs 22 is utilized to insert the arc-shaped push-off strips 21 into the arc-shaped grooves of the triangular plug block 18 to prevent the support strip 17 from rebounding.

[0034] When the pedal rod 5 rotates, it can drive the support bar 17 to rotate synchronously, and the support bar 17 drives the triangular plug block 18 to insert into the insertion cavity of the limit plate 15, and the top of the support bar 17 is close to the bottom of the limit plate 15, and the arc groove on the triangular plug block 18 can contact the outer side of the arc-shaped support bar 21. When the arc groove is aligned with the arc-shaped support bar 21, the elasticity of the spring 22 is used to pull the installation bar 19 to move, so that the installation bar 19 pushes the insertion rod 20 to insert the arc-shaped support bar 21 into the arc groove of the triangular plug block 18, providing a limit for the triangular plug block 18, so that when the staff climbs, they can use the contact between the limit plate 15 and the support bar 17 and the arc-shaped support bar 21 to position the triangular plug block 18, thereby increasing the bearing capacity of the pedal rod 5, and when the staff's hands or feet are away from the pedal rod 5, it can prevent the pedal rod 5 from rebounding, thereby achieving the effect of improving the safety of climbing.

[0035] Working principle: First, the staff rotates the rotating rod 6, so that the rotating rod 6 drives the corresponding sleeve 8 on the moving cylinder 7 to move along the outer side of the positioning rod 9 through its multiple external threads, and the moving cylinder 7 can be in an upward moving state. At this time, the moving cylinder 7 drives the two U-shaped frames 13 to move synchronously, and the U-shaped frame 13 drives the rack plate 14 to move along the slide groove on the inner side of the support plate 4, so that the rack plate 14 drives the gear 12 to rotate, and the gear 12 drives the mounting rod 11 at one end of the pedal rod 5 to rotate, so that multiple pedal rods 5 are synchronously turned outward from the storage groove of the support plate 4, and are 90 degrees with the support plate 4. At the same time, the pedal rod 5 drives the support bar 17 to rotate upward, and the top of the support bar 17 is close to the bottom of the limit plate 15, and drives the triangular plug block 18 to insert into the insertion cavity of the limit plate 15. The outer side of the triangular plug block 18 contacts the outer side of the arc-shaped abutment bar 21. When the arc groove of the triangular plug block 18 is aligned with the arc-shaped support bar 21, the elasticity of the spring 22 is used to pull the installation bar 19 to move, so that the installation bar 19 pushes the insertion rod 20 to move the arc-shaped support bar 21 synchronously, and the arc-shaped support bar 21 is inserted into the arc groove of the triangular plug block 18 to provide a limit for the triangular plug block 18. The staff can climb through multiple pedal rods 5, and use the contact between the limit plate 15 and the support bar 17, and the arc-shaped support bar 21 to position the triangular plug block 18, so as to improve the bearing capacity of the pedal rod 5, thereby ensuring the safety of the staff when climbing. Finally, the staff completes the maintenance of the line tower and climbs down to the tower base 1. The rotating rod 6 can be turned again to recycle the pedal rod 5 to prevent irrelevant personnel from climbing, and to provide protection for the pedal rod 5, thereby improving the durability of the pedal rod 5, thereby achieving the effect of improving the convenience and safety of high-altitude climbing.

An adjusting rod 25 is rotatably mounted on the inner side of the vertical plate 24. A matching conical wheel 26 is fixedly mounted on one end of the adjusting rod 25 and the outer side of the rotating rod 6. The rotating adjusting rod 25 can drive the rotating rod 6 to rotate through the conical wheel 26. An observation port for the adjusting rod 25 to rotate and adjust is provided on the outer side of the support plate 4. A protective plate 27 is provided on the inner side of the observation port. The size of the protective plate 27 is larger than that of the observation port, so as to improve the sealing performance of the protective plate 27 to the observation port. A slide bar 28 is fixedly installed on the top of the protective plate 27, and a cavity is opened on the inner side of the observation port for the protective plate 27 and the slide bar 28 to slide in a limited position. Three springs 29 equidistantly distributed are fixedly installed between the top of the slide bar 28 and the top inner wall of the cavity to facilitate pushing the protective plate 27 to reset. A push rod 30 is fixedly installed on the side of the protective plate 27 away from the adjusting rod 25. Grooves matching the push rod 30 are opened at the top and bottom of the observation port, and magnet strips 31 are fixedly installed on both sides of the push rod 30. The inner side of the observation port is made of magnetically attractive metal material, which is convenient for opening and locking the protective plate 27 upward.

[0037] In this embodiment: the staff can drive the protective plate 27 to move along the inner side of the observation port through the push rod 30, so that the magnet bar 31 on the push rod 30 contacts the top of the observation port for magnetic locking. The staff can then rotate the adjusting rod 25 to drive the conical wheel 26 to rotate, so that the conical wheel 26 drives the conical wheel 26 on the rotating rod 6 to rotate, so that multiple pedal rods 5 can be adjusted synchronously, and when closing the protective plate 27, the elasticity of the spring 29 can be used to make the protective plate 27 quickly seal the observation port, thereby improving the adjustment efficiency of the adjusting rod 25 when climbing at high altitude, thereby improving the safety of high altitude climbing.

A plurality of equidistantly distributed anti-skid ribs 35 are provided on the side of the pedal rod 5 close to the rotating rod 6 to improve the safety of the staff's footsteps. A sliding frame 36 is fixedly installed on the outer side of the rack plate 14, and the outer side of the sliding frame 36 contacts the inner side of the support plate 4 to ensure that the rack plate 14 drives the gear 12 to rotate smoothly. An adjusting handle 37 is fixedly installed on the end of the adjusting rod 25 away from the conical wheel 26.

[0039] In this embodiment: when the staff install the support plate 4, they can fix the two mounting plates 32 on the support frame 2 by bolts, and when installing the next support plate 4, they first plug the slot on the support plate 4 into the positioning plug block 34 on the installed support plate 4 to improve the convenience and firmness of the safety between the multiple support plates 4, and the protective ring 33 on the outside of the support plate 4 can be used by the staff to install a safety rope, thereby improving the safety of high-altitude climbing and operation;

[0040] The staff can drive the adjusting rod 25 to rotate by adjusting the handle 37, thereby improving the convenience of rotating and adjusting the adjusting rod 25. When the U-shaped frame 13 drives the rack plate 14 to move, it can drive the sliding frame 36 to move along the inner side of the support plate 4, ensuring that the rack plate 14 moves smoothly along the slide groove of the support plate 4, ensuring that the rack plate 14 drives the gear 12 to rotate and provides a limit for the gear 12. The anti-slip ribs 35 on the pedal rod 5 can increase the friction force on the surface of the pedal rod 5, thereby improving the safety of the staff when climbing and holding.
