Description

Technical Field

[0001] The utility model relates to the field of conductor traction plates, in particular to a one-traction-five-traction plate with a heavy hammer placed below. Background Art

[0002] At present, high-voltage transmission lines all use multi-split conductors, among which four-split, six-split, and eight-split conductors are more common. The specific construction method depends on the number of conductor splits and the conductor rules. Commonly used construction methods include "one-to-two" and "one-to-four". The common feature of these methods is that one traction wire rope pulls an even number of sub-conductors at the same time to achieve force balance.

[0003] Transmission lines in high altitude areas usually reduce corona discharge by increasing the conductor cross-sectional area. In areas with harsh terrain, increasing the conductor cross-sectional area will increase construction costs and construction difficulties. In principle, increasing the number of conductor splits is also an alternative method to increase the conductor cross-sectional area. Using a ten-split conductor in high altitude areas can solve the above problems.

[0004] In the construction of very split conductors in high-altitude areas, the existing "one-pull-two" and "one-pull-four" traction plates can be used to pull the conductors, but the "one-pull-two" and "one-pull-four" traction plates are mainly used for the traction of double-split, quadruple-split, hexa-split or octave-split conductors. For very split conductors, five "one-pull-two" methods are required, or two "one-pull-four" and one "one-pull-two" methods can be used for traction and deployment. The number of tractions is large and the construction efficiency is low. Utility Model Content

[0005] The technical problem to be solved and the technical task proposed by the utility model are to improve and perfect the existing technical solutions and provide a one-to-five traction plate with a weight under the weight to improve the traction efficiency. To this end, the utility model adopts the following technical solutions.

[0006] The one-pull-five traction plate with a weight under it includes a walking plate body, a sub-plate, a connecting nose and a weight. The sub-plate is provided with 5 pulling plates in total. The 5 pulling plates are arranged in parallel and equidistantly in the front-to-back direction and are rotatably connected to the right part of the walking plate body. The pulling plates are arranged from front to back as the first plate, the second plate, the third plate, the fourth plate and the fifth plate, respectively. The 5 pulling plates are all provided with wire connection holes. The weight of the traction plate is balanced front and back with the third plate as the boundary. The connecting nose is provided on the left side of the third plate. Two hinge holes are provided on the right side of the third plate in the upper and lower positions. The lower hinge hole is hingedly connected with the weight, and the upper hinge hole is used as a wire connection hole. By connecting the weight to the lower side of the middle pulling plate and connecting the connecting nose to a pulling wire rope, the 5 pulling plates can be directly connected to the 5 pulling wires, so that the traction plate can stably and reliably pull the 5 wires with the "one-pull-five" traction. Compared with the traditional "one-pull-two" and "one-pull-four" traction plates, the traction times can be effectively reduced, and the traction efficiency of the ten-cracked wires can be improved.

[0007] As a preferred technical means: a plurality of anti-collision blocks are arranged on the upper side of the weight in a left-right direction, so as to facilitate the traction plate to fix the position of the middle wire when passing through the wire-releasing pulley, and prevent the wire from being damaged by the impact of the weight.

[0008] As a preferred technical means: the right part of the walking board body is provided with 5 pull-plate connection positions, each of which includes 2 front-to-back parallel hinged plates, the left end of each pull-plate is arranged between the 2 hinged plates of the corresponding pull-plate connection position, the pull-plate and the hinged plate are provided with coaxial hinge holes penetrating front and back, and can be rotatably hinged through the hinge shaft. The hinged rotatable connection has a firm structure, and is stable and reliable.

[0009] As a preferred technical means: the hinge axis is a long axis, which passes through the five pull plate connection positions and the five pull plate hinge holes for hinge connection. Compared with independent hinges, hinge connection through a long axis makes the installation structure simpler.

[0010] As a preferred technical means: the five pull plates have the same structure and size. With the same structure and size, only one processing technology is needed, which can improve the convenience of processing and manufacturing.

[0011] As a preferred technical means: the right side of the first plate, the second plate, the fourth plate and the fifth plate in the pull plate is only provided with a hinge hole as a wire connection hole, and the vertical height of the first plate, the second plate, the fourth plate and the fifth plate is 50-60% of the vertical height of the third plate. Since the first plate, the second plate, the fourth plate and the fifth plate are only used for connecting wires and only need one hinge hole, they do not need the vertical height of the third plate, which can effectively save materials and reduce weight.

[0012] As a preferred technical means: the hinged plate and the connecting nose are both welded and fixed to the walking board body. The whole structure is formed by direct welding of the plate material, which is simpler and more convenient to manufacture than integral casting, and saves the mold opening cost.

[0013] Beneficial effect: By connecting the heavy hammer to the lower side of the middle pull plate and connecting the connecting nose to a traction wire rope, 5 pull plates can be directly connected to 5 traction conductors, and the connection and traction of 5 sub-conductors of a 10-split conductor can be achieved at the same time. For the 10-split conductor, only 2 release and traction are needed. Compared with the traditional "one-pull-two" and "one-pull-four" traction plates, it can effectively reduce the number of tractions and improve the traction efficiency of the 10-split conductors.

[0019] Example 1

[0020] like Figure 1 , 2As shown, the weight 3 is placed below the one-pull-five traction plate, including a walking plate body 1, a sub-plate, a connecting nose 2 and a weight 3. The left front side and the left rear side of the walking plate body 1 are both beveled angles, which can reduce the weight of the walking plate body 1. The sub-plate is provided with 5 pulling plates 4, and the 5 pulling plates 4 are arranged in parallel and equidistantly in the front and back directions, and are rotatably connected to the right part of the walking plate body 1. The pulling plates 4 are arranged from front to back as the first plate, the second plate, the third plate, the fourth plate and the fifth plate, and the 5 pulling plates 4 are all provided with wire connecting holes 401. The weight of the traction plate is balanced front and back with the third plate as the boundary. A connecting nose 2 is provided on the left side of the third plate, and two hinged holes are provided on the right side of the third plate at the upper and lower positions. The lower hinged hole is hingedly connected to the weight 3, and the upper hinged hole serves as the wire connecting hole 401.

[0021] In order to prevent the wire from being damaged by the impact of the heavy hammer 3, three anti-collision blocks 5 are arranged at equal intervals in the left and right directions on the upper side of the heavy hammer 3. It is convenient for the traction plate to fix the position of the middle wire when passing through the wire-laying pulley to prevent the wire connected to the middle pull plate 4 from being damaged by the impact of the heavy hammer 3.

[0022] In order to make the rotatable connection between the auxiliary plate and the walking plate body 1 stable and reliable, the right part of the walking plate body 1 is provided with 5 pull plate connection positions, each pull plate connection position includes 2 front and rear parallel hinge plates 6, the left end of each pull plate 4 is arranged between the two hinge plates 6 of the corresponding pull plate connection position, the pull plate 4 and the hinge plate 6 are provided with coaxial hinge holes penetrating front and rear, and can be rotatably hinged through the hinge shaft 7. The hinged rotatable connection is firm in structure, stable and reliable.

[0023] In order to simplify the connection structure, the hinge shaft 7 is a long shaft, which passes through the five pull plate connection positions and the hinge holes of the five pull plates 4. Compared with independent hinges, the installation structure is simpler through the hinge of a long shaft.

[0024] In order to reduce the complexity of the process and realize the complete replaceability of the pull plates 4, the five pull plates 4 have the same structure and size. With the same structure and size, only one processing technology is needed, which can improve the convenience of processing and manufacturing, and realize the complete replaceability of the pull plates 4.

[0025] In this example, the hinge plate 6 and the connection nose 2 are both welded and fixed to the walking board body 1. The whole structure is formed by direct welding of the sheet materials, which is simpler and more convenient to manufacture than integral casting, and saves the mold opening cost.

[0026] When in use, the connection nose 2 at the front end of the walking board body 1 is connected to a rotary connector, and the traction wire rope is connected through the rotary connector. The wire connection holes 401 of the five pulling plates 4 are each connected to a rotary connector, and the sub-conductors of the ten-split wire are connected through the rotary connector. The traction machine drags the traction wire rope, and the traction wire rope simultaneously drags the five wires forward through the lower traction plate of the heavy hammer 3, so as to realize the "one pull five" tension wire release. The utility model connects the heavy hammer 3 to the lower side of the middle pulling plate 4, and the five pulling plates 4 can directly connect the five traction sub-conductors, so as to realize the stable and reliable "one pull five" traction of the five wires. Compared with the traditional "one pull two" and "one pull four" traction plates, the traction times of the ten-split wires can be effectively reduced, and the traction efficiency of the ten-split wires can be improved.

[0027] Example 2

[0028] Different from the above examples, the right sides of the first plate, the second plate, the fourth plate and the fifth plate in the pull plate 4 are each provided with only one hinge hole as a wire connection hole 401, and the vertical height dimensions of the first plate, the second plate, the fourth plate and the fifth plate are 50% of the vertical height dimension of the third plate. Since the first plate, the second plate, the fourth plate and the fifth plate are only used for connecting wires and only need one hinge hole, they do not need the vertical height dimension of the third plate, which can effectively save materials and reduce weight.

[0029] above Figure 1 , 2 The shown one-pull-five traction plate with the weight 3 placed below is a specific embodiment of the utility model, which has embodied the substantial characteristics and progress of the utility model. According to actual use needs and under the guidance of the utility model, equivalent modifications in shape, structure, etc. can be made to it, which are all within the protection scope of this scheme.
