Description

Technical Field

[0001] The invention relates to the field of hoisting equipment, and in particular to a ground wire hoisting equipment for a transmission line tower. Background Art

[0002] The ground wire lifting equipment for power transmission line tower is a device specially used to lift and move the ground wire to the installation position of the power transmission line tower. Since the ground wire needs to be installed at the top of the power transmission line tower, the ground wire has a certain weight and length, so the lifting equipment is needed to lift the ground wire from the ground to the top of the power transmission line tower for installation, which plays the effect of lifting the ground wire and is widely used in the construction of power transmission line towers.

[0003] A Chinese patent with authorization announcement number CN214167181U discloses a light lifting device for power transmission lines, which uses an adjusting device to adjust the position of a fixing device, and through the fixing device, the whole is quickly fixed and installed with the iron tower to form a lifting frame, which is convenient for staff to transport materials. Although it can improve work efficiency, save labor, and meet the needs of use, when the existing lifting equipment is used, the pole tower has a conical structure, so the top side of the pole tower is inclined. When the ground wire is lifted, the ground wire will contact with the pole tower through friction, resulting in damage to the ground wire, and the ground wire cannot be safely lifted and installed. At the same time, the top position of the pole tower is limited, and the lifting position cannot be changed, resulting in the lifting equipment being unsuitable for lifting the ground wire of the pole tower. In addition, the lifting equipment is an integral structure with a fixed volume. When used in different occasions on the pole tower, the use effect of the lifting equipment is also limited. It can only be lifted and lifted individually, and cannot be lifted at local corners, which is not convenient for lifting needs of ground wires at different positions. Moreover, after the ground wire is lifted, it cannot be reeled up. The ground wire that is too long is placed on the top of the pole tower, which is prone to entanglement and other problems, which brings inconvenience to the installation of the ground wire after lifting.

The positioning rod 26 has the effect of positioning the telescopic screw 25 to prevent the telescopic screw 25 from rotating itself.

[0036] As a further solution of the present invention, the first positioning sleeve 21 and the second gear 22 are inserted into the interior of the fixed top plate 6 and are fixed by screws, the telescopic screw 25 is threadedly connected to the threaded sleeve 23, and one end of the telescopic screw 25 and the positioning rod 26 is movably mounted with a fixed splint 27, and one side of the fixed splint 27 is threadedly mounted with a locking knob 28, and the other end of the telescopic screw 25 and the positioning rod 26 is fixedly mounted with a wire wheel 29, and the fixed splint 27 is used to be clamped on the pole tower and tightened and fixed by the locking knob 28.

[0037] As a further solution of the present invention, the traction rope 30 passes through the retractable guide frame 5 and bypasses the wire wheel 29. The wire wheel 29 can guide the traction rope 30 parallel to one side and then pass it downward. The end of the traction rope 30 is fixedly installed with a traction sling 31, and the traction sling 31 is used to connect and lift the bottom line.

[0038] As a further solution of the present invention, the roller structure 33 includes a roller shaft 34, a ground wire roller 35 and a rotating bevel gear 36. The two roller shafts 34 are arranged at the center of the two roller clamps 32. The ground wire roller 35 is fixedly installed in the middle of the two roller shafts 34. The rotating bevel gear 36 is fixedly installed at the upper end of the roller shaft 34 and is meshed with the extended bevel gear 19. When the gear fixing seat 15 is at the rear, the rotating bevel gear 36 is meshed with the extended bevel gear 19.

[0039] As a further solution of the present invention, a clamping spring is embedded in the center of the roller clamp 32, and the roller shaft 34 is clamped into the clamping spring and movably connected to the roller clamp 32. The ground wire roller 35 is located behind the retractable roller 7, and the ground wire roller 35 rotates around the inner side of the roller clamp 32 through the roller shaft 34.

[0040] It should be noted that the present invention is a ground wire hoisting device for a power transmission line tower. When in use, the hoisting device is carried to the ground wire installation position at the top of the tower. After the motor in the motor base 1 is running, the motor shaft 9 and the lifting transmission shaft 10 are driven to rotate. The lifting transmission shaft 10 then drives the reel 7 to rotate through the transmission bevel gear 12. The rotation of the reel 7 is used to reel in and out the traction rope 30. Then, the traction rope 30 passes through the reel guide frame 5 to lift and pull the traction hoist 31. The ground wire is installed by the traction hoist 31. Then, after the traction rope 30 is reeled in, the traction hoist 31 and the ground wire are lifted to lift the ground wire to the ground wire installation position at the top of the tower.

[0041] When the ground wire is hoisted at the top of the tilted tower, the lifting device is held by the gripping handle 4, and the transmission bevel gear 12 is pulled upward through the lifting pull ring 13 to move the lifting transmission shaft 10 upward. At the same time, the transmission gear 11 is separated from the gear slot 8, so that the rotation of the lifting transmission shaft 10 will not drive the reel 7 to rotate. After the transmission bevel gear 12 is raised, it is meshed and connected with the driven bevel gear 17. The rotation of the lifting transmission shaft 10 causes the transmission bevel gear 12 to drive the driven bevel gear 17 to rotate, and then the first gear 16 drives the driven bevel gear 17 to rotate, and the first gear 16 is connected to the driven bevel gear 17. The rotation of the second gear 22 also drives the meshing connection to rotate, thereby rotating the threaded sleeve 23 on one side of the second gear 22, and the threaded sleeve 23 drives it to move left and right through the threaded connection with the telescopic screw 25, and finally moves the telescopic screw 25 to one side above the fixed top plate 6 to extend, so that the wire wheel 29 at one end is away from the reel 7, and then when the traction rope 30 is hoisting the ground wire, the traction rope 30 first moves parallel to bypass the wire wheel 29, and then hoists the ground wire perpendicularly to avoid the tilt angle of the pole tower, so as to prevent the friction contact between the ground wire and the pole tower when it is raised;

[0042] When the lifting position needs to be changed, the fixing clamp 27 is sleeved on the bracket of the pole tower, and the locking knob 28 is tightened to position the fixing clamp 27 to fix and install the telescopic screw 25, so that the telescopic screw 25 is in a fixed state. Therefore, when the threaded sleeve 23 is rotated again, the threaded sleeve 23 moves left and right through the threaded connection with the telescopic screw 25, driving the lower part of the fixed top plate 6 to move left and right under the telescopic screw 25, changing the use position of the lifting device, and coordinating with the ground wire lifting at different positions;

[0043] When used in different occasions, the screws on the first positioning sleeve 21 and the second positioning sleeve 24 can be removed to separate them from the fixed top plate 6, and the telescopic screw 25 can be moved out. At the same time, the second gear 22 is also separated from the first gear 16, so that the overall volume of the lifting device is reduced. When the lifting device is grasped and moved by grasping the handle 4, it can be lifted and used in any position, and it can be used for lifting in different occasions;

[0044] After the first positioning sleeve 21 and the second positioning sleeve 24 are removed, the gear fixing seat 15 is slid 90° above the fixed top plate 6 and then the screws are tightened to position it, so that the extended bevel gear 19 can be meshed and connected with the rotating bevel gear 36. When the driven bevel gear 17 and the first gear 16 rotate, the transmission rod 18 and the extended bevel gear 19 are also driven to rotate, so that the rotating bevel gear 36 rotates together with the extended bevel gear 19, thereby causing the winding roller shaft 34 and the ground wire winding roller 35 below the rotating bevel gear 36 to rotate, and the rotation of the ground wire winding roller 35 is used to reel in the hoisted ground wire. The winding roller shaft 34 can also be pulled out from the winding roller clamp 32 to cooperate with the installation and use of the hoisted and reeled ground wire.

[0045] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
