Description

Technical Field

[0001] The invention relates to the technical field of pole tower power line protection, and in particular to a pole tower power line decoupling device and a use method thereof. Background Art

[0002] The transmission line tower structure is a special supporting structure in the power overhead line facilities. Its structural performance directly affects the safety, economy and operational reliability of the line. With the development of my country's power grid, the transmission line project shows a trend of long distance, large scale and large-scale development.

[0003] The use of high-position tower cables requires great consideration of load-bearing performance and stability. Existing means include a tower power line decoupling device disclosed in publication number CN111030014A, which proposes a technical problem of effectively reducing the load of the tower before the tower reaches its ultimate bearing capacity in the horizontal or along-line direction and protecting the tower from damage. Specifically, a hoisting assembly, an along-line decoupling assembly and a horizontal decoupling assembly are set up. Considering the load-bearing effect, a first rigid bracket with a high-strength structure, an anti-side-slip rigid connector and a second rigid bracket are used in the hoisting assembly. However, this will greatly increase the load-bearing pressure of the high-position cables, and at the same time, it is necessary to ensure that the rigid structures are stable. In order to ensure the firm connection between the cables, a large number of connecting and assembling parts are added, which leads to a large size and weight, and also increases the workload and difficulty of disassembly and assembly operations; although the inline unhooking components and the horizontal unhooking components can cope with the forces in two directions to maintain stability, the unhooking components that mostly use a fixed connection structure are difficult to adapt to the state adjustment of the cables in different dimensions, especially in the high-rise environment, the cables are very easy to be telescopically adjusted in multiple directions and dimensions, especially they are very easy to be stretched and pulled in the vertical direction. If the lifting components used to fix the installation of cables lack targeted buffering measures, it is very easy to cause secondary traction damage to the cables, and even cause cable detachment and breakage accidents.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention utilizes a half-hole fixed block and a set extension plate to form a load-bearing hanger, and utilizes a load-bearing square plate and a mountain-shaped set block to form a connecting hanger. By mutually fitting the set extension plate and the mountain-shaped set block, the close connection between the two is strengthened to ensure the high-position connection and the firmness of the load-bearing.

The pole tower power line decoupling device also includes a connecting hanger 2, a hanging frame 3, and a boss hanging part 4: The connecting hanger 2 is assembled and connected with the load-bearing hanger 1, and the load-bearing hanger 1 is fixedly connected to the tower through the connecting hanger 2. The connecting hanger 2 is provided with a first buffer portion 6 for movably mounting the hanger 3, and the hanger 3 moves along the front and rear directions through the first buffer portion 6 to pull the cable. The load-bearing hanger 1 is composed of a half-hole fixing block 101 and a set extension plate 102: There are two half-hole fixing blocks 101, and the two half-hole fixing blocks 101 are used to fit the tower pole.

[0022] There are two set extension plates 102 , and the two set extension plates 102 are respectively connected to the lower ends of the two half-hole fixing blocks 101 in one piece.

[0023] The connecting pendant 2 is composed of a load-bearing square plate 201 and a mountain-shaped set block 202: The load-bearing square plate 201 is arranged horizontally, and the U-shaped set block 202 is integrally connected to the load-bearing square plate 201, and the U-shaped set block 202 is set connected to the set extension plate 102. The set extension plate 102 and the U-shaped set block 202 are embedded in each other to increase the connection strength between the load-bearing hanger 1 and the connecting hanger 2, and a multi-point connection between the two is achieved using a limited structure.

[0024] The specific connection method is to set a fixing part 5, a fixing part 5 is set between the mountain-shaped set block 202 and the set extension plate 102, the load-bearing hanger 1 is fixedly connected to the connecting hanger 2 through the fixing part 5, and the load-bearing hanger 1 is fixed to the set tower pole through the fixing part 5, and the fixing part 5 includes a locking through hole 501, a locker 502, an eccentric annular groove 503, a lifting plate 504, a curved connecting cavity 505, a limit bayonet 506, a driven piston limit bolt 507, a first spring 508, and a booster piston 509: The locking through hole 501 is correspondingly opened in the set extension plate 102 and the mountain-shaped set block 202, and the locker 502 is installed on the set extension plate 102 and the mountain-shaped set block 202 through the locking through hole 501. It should be noted that the locker 502 adopts a threaded rod structure, and the locker 502 can be flipped 180° in the locking through hole 501. By locking and fixing the locker 502, the tower pole, the load-bearing hanger 1, and the connecting hanger 2 can be connected in sequence.

[0025] The eccentric annular groove 503 is provided in the locking device 502. Figure 3 With attached Figure 4 It should be noted that, due to the difference in the inner circle depth of the eccentric ring groove 503, it is convenient to install the locker 502 in the locking through hole 501, and the lifting plate 504 can be pressed by flipping the locker 502, so that the lifting plate 504 can contact the booster piston 509 when it extends upward.

[0026] The lifting bottom plate 504 is slidably sleeved in the mountain-shaped sleeve block 202, and the lifting bottom plate 504 is movably abutted against the eccentric ring groove 503.

[0027] The curved connecting cavity 505 is opened in the half-hole fixing block 101. It should be noted that the curved connecting cavity 505 is composed of a C-shaped tube and a right-angle tube, so that the curved connecting cavities 505 and the limit bayonet 506 in the two half-hole fixing blocks 101 can be misaligned, so that the driven piston limit bolt 507 in one half-hole fixing block 101 can extend and be buckled into the limit bayonet 506 on the other half-hole fixing block 101.

[0028] The limit bayonet 506 is correspondingly opened at the top end of the half-hole fixing block 101 corresponding to the upper end opening of the curved connecting cavity 505.

[0029] The driven piston limit bolt 507 is slidably sleeved in the upper end opening of the curved connecting cavity 505.

[0030] The first spring 508 is fixedly installed at the lower end of the half-hole fixing block 101.

[0031] The pressurizing piston 509 is slidably sleeved in the lower end opening of the curved connecting cavity 505, and the pressurizing piston 509 that movably abuts against the lifting bottom plate 504 is fixedly connected to the first spring 508. It should be noted that by setting the first spring 508, the pressurizing piston 509 that is not pressurized by the lifting bottom plate 504 always maintains a tendency to extend out of the lower end opening of the curved connecting cavity 505, thereby pulling the driven piston limit bolt 507 to contract into the upper end opening of the curved connecting cavity 505, which is convenient for assembling the two half-hole fixing blocks 101 together.

[0032] The suspension bracket 3 is movably installed in the connection hanging part 2. The second buffer part 7 for movably installing the convex platform hanging part 4 is arranged in the suspension bracket 3, and the convex platform hanging part 4 movably pulls the cable along the up and down direction through the second buffer part 7. For details, refer to the attached Figure 3 、attached Figure 4 、attached Figure 6 -attached Fig. 9 The first buffer part 6 includes a guiding long hole 601, a first mountain-shaped long cavity 602, a guiding bracket 603, a synchronous truss 604, a driving piston part 605, a second spring 606, and a driven piston part 607: The guiding long holes 601 are symmetrically opened at the left and right ends of the load-bearing square plate 201, and the guiding long holes 601 are opened along the front and back direction of the cable erection.

[0033] For details, refer to the attached Figure 8 The first mountain-shaped long cavity 602 is symmetrically opened at the front and back ends of the load-bearing square plate 201.

[0034] The guide bracket 603 is slidably mounted in the guide long hole 601 , and the synchronous truss 604 is used to fix and connect the two guide brackets 603 , so that the guide brackets 603 at the left and right sides move synchronously.

[0035] The driving piston 605 is slidably mounted in the guide long hole 601 and the side opening of the first U-shaped long cavity 602 , and the driving piston 605 is fixedly connected to the guide bracket 603 .

[0036] The second spring 606 is fixedly connected to the middle opening of the first U-shaped long cavity 602. It should be noted that the second spring 606 ensures that the guide bracket 603 is always located in the middle position of the guide long hole 601 when not affected by the cable.

[0037] The driven piston member 607 is slidably mounted in the middle opening of the first U-shaped long cavity 602, and is fixedly connected to the driven piston member 607 of the second spring 606 to flexibly abut against the synchronous truss 604. The squeezed driven piston member 607 moves forward and backward to flexibly abut against the synchronous truss 604, so that the synchronous truss 604 moves to the initial position to avoid excessive deviation of the cable.

[0038] The boss suspension member 4 is movably mounted on the suspension frame 3, and the binding member 8 is mounted on the boss suspension member 4. For details, please refer to the attached manual. Fig. 9 With attached Fig.10 The second buffer part 7 includes a guide support rod 701, a second mountain-shaped long cavity 702, a driven piston long bolt 703, a third spring 704, an active piston pulley 705, a steering pulley 706, a wedge head telescopic rod 707, a driving wedge head block 708, a driven wedge head block 710, and a traction rope 711: The guide support rod 701 is fixedly connected to the lower end of the suspension frame 3, and the guide support rod 701 is slidably mounted in the boss hanger 4. It should be noted that when the cable is pulled in the vertical direction, the boss hanger 4 moves up and down along the guide support rod 701 under the traction of the binding member 8.

[0039] The second U-shaped long cavity 702 is opened in the suspension frame 3 .

[0040] The driven piston long bolt 703 is slidably mounted in the side opening of the second mountain-shaped long cavity 702 .

[0041] The third spring 704 is fixedly installed at the lower end of the suspension bracket 3. It should be noted that by setting the third spring 704, the active piston pulley 705 always has a tendency to extend out of the middle end opening of the second mountain-shaped long cavity 702, thereby pulling the two driven piston long bolts 703 to shrink into the openings at both ends of the second mountain-shaped long cavity 702.

[0042] The active piston pulley 705 is fixedly connected to the third spring 704 , and the active piston pulley 705 is slidably mounted on the middle opening of the second mountain-shaped long cavity 702 .

[0043] The steering pulley 706 is fixedly installed at the lower end of the suspension frame 3. There are two steering pulleys 706, which are symmetrically arranged on the left and right sides of the active piston pulley 705, and the steering pulley 706 is always located above the active piston pulley 705, thereby ensuring that the traction rope 711 installed through the active piston pulley 705 and the steering pulley 706 is an M-shaped structure.

[0044] The wedge head telescopic rod 707 is horizontally slidably mounted in the guide bracket 603, and the wedge head telescopic rod 707 slides against the boss suspension member 4. When the boss suspension member 4 moves upward, the two wedge head telescopic rods 707 move in opposite directions and gradually move away from each other. When the boss suspension member 4 moves downward, the two wedge head telescopic rods 707 move toward each other and gradually approach each other.

[0045] The driving wedge block 708 is vertically slidably mounted on the guide bracket 603, and the driving wedge block 708 is movably pulled by the driven piston long bolt 703. A pulling connecting rod 709 is pin-connected between the driven piston long bolt 703 and the driving wedge block 708, and the driven piston long bolt 703 is used to pull the driving wedge block 708 to rise and fall vertically.

[0046] The driven wedge head block 710 is integrally connected to the wedge head telescopic rod 707 , and the driven wedge head block 710 slides against the driving wedge head block 708 .

[0047] The traction rope 711 is fixedly connected to the two wedge head telescopic rods 707 through the active piston pulley 705 and the steering pulley 706. The traction rope 711 applies pressure to the active piston pulley 705 while being gradually tightened by the wedge head telescopic rod 707. After the impact effect is reduced by the second mountain-shaped long cavity 702, the extension of the driven piston long bolt 703 is achieved, thereby forcing the driving wedge head block 708 to squeeze the driven wedge head block 710, so that the wedge head telescopic rod 707 resets itself, avoiding excessive lifting and displacement of the boss suspension member 4.

[0048] It should be noted that the specific models and specifications of the tower pole and the binding member 8 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in this field, so it is not repeated here.

[0049] The present invention can be explained by the following operation mode: First, the two half-hole fixing blocks 101 are combined and sleeved on the tower pole, and then the two sleeve extension plates 102 are sleeved in the mountain-shaped sleeve block 202. After the lifting and lowering plate 504 is pulled upward, the locker 502 is placed in the locking through hole 501. After loosening the lifting and lowering plate 504, its lower end is movable and extended to the eccentric ring groove 503, and the locker 502 is rotated to 180°. Due to the guiding and limiting effect of the half-hole fixing block 101, the lifting and lowering plate 504 moves vertically upward and resists the booster piston 509 to move into the curved connecting cavity 505, so that the driven piston limit bolt 507 extends from the curved connecting cavity 505 to the limit bayonet 506. The load-bearing hanger 1 is assembled and connected with the tower pole and the connecting hanger 2 by fixing the locker 502. The locker 502 is fixed in the sleeve extension plate 102 and the mountain-shaped sleeve block 202 by tightening the screws and nuts on the locker 502. Secondly, the cables are fixedly mounted on the boss hanger 4 using the binding member 8 .

[0050] The cable is shaken by external force: When the cable moves in the front-to-back direction, the binding member 8 drives the suspension frame 3 to move forward and backward through the boss suspension member 4, and then drives the guide bracket 603 to move forward and backward and left and right along the guide long hole 601 through the synchronous truss 604, and the guide bracket 603 drives the driving piston member 605 to extend into the first mountain-shaped long cavity 602, and then squeezes the driven piston member 607 to extend out of the first mountain-shaped long cavity 602, so that the driven piston member 607 moves to resist the synchronous truss 604, so as to drive the guide bracket 603 to reset; When the cable is stretched in the vertical direction, the boss hanger 4 moves up and down along the guide support rod 701, and the boss hanger 4 applies pressure to the wedge head telescopic rod 707 to make it move horizontally. The wedge head telescopic rod 707 pulls the traction rope 711, and the gradually flattened and tight traction rope 711 squeezes the active piston pulley 705, driving the driven piston long bolt 703 to extend out of the second mountain-shaped long cavity 702, and the wedge head block 708 is squeezed and driven to move vertically by the traction connecting rod 709 to squeeze the driven wedge head block 710 located on the wedge head telescopic rod 707, so that the wedge head telescopic rod 707 and the boss hanger 4 tend to reset, avoiding the boss hanger 4 from excessive lifting and lowering and causing displacement.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
