Description

Technical Field

[0001] The utility model relates to the field of steel strands, in particular to a protection device for steel strands of transmission tower poles. Background Art

[0002] According to application number 202121389688.9, an efficient protection device for steel strands for transmission tower poles is provided, which relates to the technical field of steel strands and includes a protective shell, baffles fixedly installed around the top of the protective shell, a steel strand embedded near the middle of the baffle at the top of the protective shell, a fixed plate fixedly installed at the bottom of the protective shell, a strong spring elastically connected to the bottom of the fixed plate, and a movable plate elastically arranged at the bottom of the strong spring. In the utility model, when a worker is near the steel strand and accidentally hits the steel strand with a heavy object, the heavy object will contact the surface of the shock-absorbing plate. At this time, the shock-absorbing plate will be pressed to cause the movable rod at the outer end to rotate through the rotating shaft and drive the slider to move toward the center of the guide rod. At the same time, the shock-absorbing plate will press the telescopic rod to retract. At this time, the spring between the two sliders will drive the slider to rebound, and the spring on the outer side of the telescopic rod will drive the telescopic rod to rebound, which can reduce the impact caused by the heavy object hitting the surface of the shock-absorbing plate, protect the steel strand from being hit, and achieve better protection effect.

[0003] However, the above solution still has certain shortcomings in actual use; after long-term use, the elastic effect of the spring will be weakened to a certain extent, thereby reducing the protection effect of the steel strand, and the guide rod in the above solution is fixed on the baffle, which makes it impossible to replace the spring, and thus the protection of the steel strand will be affected to a certain extent. For this reason, we provide a protection device for the steel strand of the transmission tower. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-5 As shown, the utility model provides a technical solution: a protection device for a transmission tower steel strand, comprising a protective sleeve 1, a group of reinforcing rods 2 are fixedly connected to the inside of the protective sleeve 1, and the other end of the reinforcing rod 2 is connected to a rubber sleeve 3, and a steel strand body 4 is arranged inside the rubber sleeve 3. By fixing the rubber sleeve 3 with the reinforcing rod 2, the rubber sleeve 3 can be made more stable during use, and the steel strand body 4 installed inside the rubber sleeve 3 can be safer during use.

[0026] A protective component 5 is provided on the outer surface of the protective cover 1. The protective component 5 includes two connecting tubes 501. Two cavities 502 are provided inside the two connecting tubes 501, and a first spring 503 is provided inside the cavity 502. The interiors of the four cavities 502 are all slidably connected with sliding rods 504, and the sliding rods 504 are connected to the first springs 503.

[0027] The first spring 503 can be installed through the opened cavity 502, and the sliding connection between the slide rod 504 and the connecting tube 501 can guide the movement of the slide rod 504, thereby ensuring the subsequent normal use of the device. At the same time, the connection between the slide rod 504 and the first spring 503 can buffer the impact force to a certain extent, thereby protecting the subsequent normal use of the steel strand body 4.

[0028] The protection assembly 5 further includes four guide plates 505 installed on the outer surface of the protection cover 1 . The outer surfaces of the four slide bars 504 all penetrate the outer surface of the guide plates 505 and extend to one side of the guide plates 505 .

[0029] The outer surfaces of the four slide bars 504 are fixedly connected with connecting blocks 506, and the outer surfaces of the connecting blocks 506 are fixedly connected with handles 507. The setting of the connecting blocks 506 can provide a certain convenience for moving the slide bars 504, and the setting of the handles 507 can provide a certain convenience for pulling the connecting blocks 506.

[0030] The outer surfaces of the two connecting cylinders 501 are slidably connected to sliding plates 508, and a second spring 509 is installed between the sliding plates 508. The outer surfaces of the two connecting cylinders 501 are fixedly connected to a group of baffles 510, and the baffles 510 are in contact with the outer surfaces of the sliding plates 508.

[0031] The sliding plate 508 that is slidably connected to the outer surface of the connecting tube 501 can guide the movement of the sliding plate 508, thereby ensuring the subsequent movement effect of the sliding plate 508. At the same time, the connected baffle 510 is detachable, which is convenient for subsequent staff to remove and replace the second spring 509, thereby ensuring the use effect of the protection component 5.

[0032] The protection assembly 5 also includes two protective plates 511, which are located on the outer surface of the protective cover 1. The two protective plates 511 are hinged to two hinge rods 512 on the side close to each other, and the other end of the hinge rod 512 is hinged to the outer surface of the sliding plate 508.

[0033] By using the sliding plate 508 and the protective plate 511 hinged between the hinged rods 512, when the protective plate 511 is displaced, the movement of the protective plate 511 can be guided to a certain extent, so that the protective plate 511 is buffered to a certain extent during the movement, and the steel strand body 4 is protected to a certain extent.

[0034] A group of electric push rods 519 are installed on the outer surface of the four guide plates 505, and the output end of the electric push rod 519 is fixedly connected to the horizontal plate 513. Through the operation of the electric push rod 519, the horizontal plate 513 can be driven to move, and then the position of the horizontal plate 513 can be adjusted, thereby ensuring the subsequent limiting effect of the slide bar 504, and ensuring the subsequent use effect of the slide bar 504.

[0035] A limiting hole 514 is provided on the outer surface of each horizontal plate 513, and the inner wall of each limiting hole 514 is slidably connected to the limiting rod 515. The outer surface of each limiting rod 515 is fixedly connected to a circular plate 516, and a tension spring 517 is installed between the circular plate 516 and the horizontal plate 513. The tension spring 517 installed between the circular plate 516 and the horizontal plate 513 can be used to limit the limiting rod 515, and the tension of the tension spring 517 itself can make the subsequent structure more tightly connected, thereby ensuring the stability of the subsequent device during use.

[0036] A locking hole 518 is provided on the outer surface of each sliding rod 504, and the outer surface of the sliding rod 504 contacts the inner wall of the limiting hole 514. The ends of each group of limiting rods 515 that are close to each other are locked with the inner wall of the locking hole 518. Through the locking connection between the limiting rods 515 and the locking holes 518, the sliding rod 504 can be limited, which can ensure the subsequent use effect of the sliding rod 504.

[0037] During use, when the elastic force of the second spring 509 is weakened, first pull the two circular plates 516 in opposite directions. During the pulling process, the limit rod 515 will slide out from the inside of the card hole 518 to release the limit on the slide bar 504. After the limit is released, the slide bar 504 is pulled in the direction of the connecting tube 501 through the provided handle 507. During the pulling process, the slide bar 504 will be disengaged from the sliding connection with the guide plate 505, and then the entire part can be removed. Then the staff will first disassemble the baffle 510. After the disassembly is completed, the limit on the sliding plate 508 will be released, and then the two sliding plates 508 will be moved in one direction to complete the disassembly of the second spring 509, which is convenient for subsequent staff to replace, and can ensure that the subsequent protection component 5 can normally protect the steel strand body 4.
