Description

Technical Field

[0001] This invention relates to the field of power transmission line laying equipment technology, specifically to a bulletproof device for a multi-split conductor laying guide plate counterweight. Background Technology

[0002] Currently, during the tensioning and laying of transmission lines, when the conductor runner passes the pulley, the runner's weight can bounce upwards due to inertia. In severe cases, this can damage insulator strings or pulley positioning bolts, causing safety and quality hazards, or even accidents. With the rapid development of power grid construction, multi-split conductor stringing is widespread, with increasingly larger conductor cross-sectional areas and more splits. The runner's weight has also become longer and heavier. During stringing construction, instances of the weight bouncing and damaging insulators and positioning bolts occur frequently. Therefore, there is an urgent need for a device that can prevent bounce-offs to effectively prevent such safety and quality hazards. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention aims to provide a bulletproof device for a multi-split conductor laying board with a heavy hammer. Using this solution, when the heavy hammer bounces over the pulley, anti-collision components block the hammer, achieving a bulletproof effect.

[0004] This invention is achieved through the following technical solution: A ballistic protection device for a multi-split conductor laying board with a counterweight, including a clamping and support mechanism located at the rear end of the board; The clamping support mechanism includes a collision protection component and a plurality of clamping components; the plurality of clamping components are evenly distributed on a plurality of wires, and the clamping components are used to clamp the wires; The upper ends of several clamping components are connected to the anti-collision component; the anti-collision component is located between two adjacent wires; the rear end of the guide plate is equipped with a counterweight. The portion of the anti-collision component is located within the rotation range of the weight.

[0005] Compared to existing technologies where the runner's weight bounces upwards due to inertia when it passes the pulley, potentially damaging insulator strings or pulley positioning bolts and causing safety and quality hazards or even accidents, this invention provides a bulletproof device for the runner's weight in multi-split conductor laying. With this solution, when the weight bounces after passing the pulley, anti-collision components block the weight, achieving a bulletproof effect. The specific solution includes a clamping and support mechanism, which comprises an anti-collision component and several clamping assemblies. The clamping assemblies are used to clamp the conductors, facilitating installation on the conductors and providing stable support for the anti-collision component. The split conductors can consist of several strands; this solution uses two strands as an example. The clamping assemblies are evenly distributed on the two conductors. Therefore, by connecting the upper end of the clamping assemblies, the anti-collision component can be installed above the conductors to offset the pulley. The anti-collision component is located between the two conductors, and its portion is within the rotation range of the counterweight. Therefore, after the boarding system enters the wire-laying pulley, the counterweight bounces up due to the collision with the pulley wheel, thus only impacting the anti-collision component. Due to the restriction of the anti-collision component, the counterweight is prevented from bouncing, and it will not collide with any facilities above the pulley, thereby protecting the relevant facilities above the pulley.

[0006] A further improvement is that the anti-collision component is made of flexible fabric or flexible mesh. The anti-collision component can have elasticity and slackness, and is made of thicker canvas or φ3.5 Dyneema rope to avoid hard contact, thus achieving a bulletproof effect through flexible shielding.

[0007] In a further embodiment, the upper end of the clamping assembly is secured to the edge of the anti-collision component using bolts. Specifically, the bolts pass through the anti-collision component, and nuts are fitted on both sides of the bolts. The opposing clamping of these nuts secures the anti-collision component, achieving a detachable connection.

[0008] A further solution involves deploying the anti-collision component by placing a steel bar between the upper ends of two corresponding clamping assemblies on two adjacent conductors, perpendicular to the conductors. The steel bar is connected to the clamping assemblies by bolts. In this solution, since the spacing between the two conductors is variable, the anti-collision component may wrinkle during tension release, reducing its bulletproof effect. Therefore, to deploy the anti-collision component, a steel bar is also provided, with both ends connected to the upper ends of the clamping assemblies on the two conductors, thereby fixing the spacing between the two conductors and improving the bulletproof performance of the anti-collision component.

[0009] A further solution, to avoid affecting the release of rotational torque between the wire and the guide plate, includes a rotating positioning sleeve and a limiting fixing sleeve. The upper end of the rotating positioning sleeve is connected to the anti-collision component. The rotating positioning sleeve rotatably houses the limiting fixing sleeve, which can rotate around the axis of the rotating positioning sleeve. The limiting fixing sleeve is used to clamp the wire. In this solution, the limiting fixing sleeve clamps and fixes the wire, and the upper end of the rotating positioning sleeve is connected to the anti-collision component. Due to the relative rotation between the rotating positioning sleeve and the limiting fixing sleeve, the rotating positioning sleeve can rotate with the wire. When multiple clamping components are combined into an integral structure by connecting positioning steel bars and anti-collision components, the release of rotational torque between the wire and the guide plate is not affected, nor does the position of the anti-collision component change due to the rotation of the wire.

[0010] A further embodiment includes a circumferential groove on the outer side of the limiting and fixing sleeve, and a circumferential slider on the inner side of the rotating positioning sleeve that matches the circumferential groove. Relative rotation is achieved through the sliding engagement between the circumferential slider and the circumferential groove.

[0011] A further embodiment includes a plurality of bearing springs circumferentially positioned between the two sides of the circumferential groove and the sides of the circumferential slider; and a plurality of needle rollers circumferentially positioned between the bottom surface of the circumferential groove and the opposite surface of the circumferential slider. The interaction between the bearing springs and the needle rollers, similar to a needle roller ball bearing, reduces friction.

[0012] In a further embodiment, one side of the circumferential groove is a positioning ring, which is detachably fitted onto the limiting and fixing sleeve. The detachable positioning ring facilitates the assembly and disassembly of the clamping components. After the positioning ring is installed in place, it can be fixed by screws and the limiting and fixing sleeve.

[0013] In a further embodiment, the upper outer side of the circumferential slider has a protrusion with bolt holes; the protrusion is connected to the edge of the anti-collision component by bolts.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. This invention provides a bulletproof device for a multi-split conductor laying board with a counterweight. With this solution, when the counterweight bounces over the pulley, the anti-collision component blocks the counterweight, achieving a bulletproof effect. The device is easy to install and disassemble, and its bulletproof effect is obvious during use. 2. This invention provides a ballistic protection device for a multi-split conductor laying board with a counterweight. Due to the relative rotation between the rotating positioning sleeve and the limiting fixing sleeve, the rotating positioning sleeve can rotate with the conductor. When multiple clamping components are assembled into an integral structure by connecting positioning steel bars and anti-collision parts, the release of rotational torque between the conductor and the board is not affected, and the position of the anti-collision parts will not change due to the rotation of the conductor.

Therefore, they should not be construed as limiting the scope of protection of this invention.

[0020] Example: This example provides a bulletproof device for a multi-split conductor laying guide plate with a counterweight, such as... Figures 1-6 As shown, it includes a clamping support mechanism 5 located at the rear end of the walkway 1; The clamping support mechanism 5 includes a collision protection member 51 and a plurality of clamping components; the plurality of clamping components are evenly distributed on a plurality of wires 4, and the clamping components are used to clamp the wires 4; The upper ends of several clamping components are connected to the anti-collision member 51; the anti-collision member 51 is located between two adjacent wires 4; the rear end of the guide plate 1 is equipped with a counterweight 2; The anti-collision component 51 is partially located within the rotation range of the weight 2.

[0021] Compared to existing technologies, where the hammer 2 of the walkway 1 bounces upward due to inertia when it passes the trolley, potentially damaging the insulator string or the trolley positioning bolt 53 and causing safety and quality hazards or even accidents, this invention provides a device to prevent the hammer from bouncing off the walkway 1. With this solution, when the hammer 2 bounces off the trolley, the anti-collision component 51 blocks the hammer 2, achieving a bulletproof effect. The specific solution includes a clamping support mechanism 5, which includes an anti-collision component 51 and several clamping components. The clamping components are used to clamp the wire 4, making it easy to install on the wire 4 and providing stable support for the anti-collision component 51. The split wire 4 can be several wires; this solution uses two wires as an example. The clamping components are evenly distributed on the two wires 4. Therefore, by connecting the upper end of the clamping components, the anti-collision component 51 can be installed above the wire 4 to stagger the pulley. The anti-collision component 51 is located between the two wires 4, and its part is within the rotation range of the counterweight 2. Therefore, after the board 1 system enters the wire-laying pulley, the counterweight 2 bounces up due to the collision with the pulley wheel, and will only hit the anti-collision component 51. Due to the restriction of the anti-collision component 51, the counterweight 2 is prevented from bouncing up by the anti-collision component 51, and the counterweight 2 will not collide with any facilities above the pulley, thereby achieving the function of protecting the relevant facilities above the pulley.

[0022] In this embodiment, the anti-collision component 51 is made of flexible fabric or flexible mesh. The anti-collision component 51 can have elasticity and slackness, and is made of thicker canvas or φ3.5 Dyneema rope to avoid hard contact, thus achieving a bulletproof effect through flexible shielding.

[0023] In this embodiment, the upper end of the clamping assembly clamps the edge of the anti-collision member 51 within it using bolts 53. That is, the bolts 53 pass through the anti-collision member 51, and nuts are fitted on both sides of the bolts 53. The anti-collision member 51 is fixed by the opposing clamping of the nuts, thereby achieving a detachable connection.

[0024] In this embodiment, to deploy the anti-collision component 51, a steel strip 52 is provided between the upper ends of two corresponding clamping components on two adjacent wires 4 along a direction perpendicular to the wires 4. The steel strip 52 is connected to the clamping components by bolts 53. In this design, since the spacing between the two wires 4 is variable, the anti-collision component 51 may wrinkle during the tension release process, reducing its bulletproof effect. Therefore, to deploy the anti-collision component 51, a steel strip 52 is also provided. The two ends of the steel strip 52 are respectively connected to the upper ends of the clamping components on the two wires 4, thereby fixing the spacing between the two wires 4 through the steel strip 52 and improving the bulletproof performance of the anti-collision component 51.

[0025] In this embodiment, to avoid affecting the release of rotational torque between the wire 4 and the guide plate 1, the clamping assembly includes a rotating positioning sleeve 55 and a limiting fixing sleeve 54. The upper end of the rotating positioning sleeve 55 is connected to the anti-collision member 51. The rotating positioning sleeve 55 rotatably sleeves the limiting fixing sleeve 54 inside it. The limiting fixing sleeve 54 can rotate around the axis of the rotating positioning sleeve 55. The limiting fixing sleeve 54 is used to clamp the wire 4. In this solution, the limiting fixing sleeve 54 is used to clamp and fix the wire 4. The upper end of the rotating positioning sleeve 55 is connected to the anti-collision member 51. Due to the relative rotation between the rotating positioning sleeve 55 and the limiting fixing sleeve 54, the rotating positioning sleeve 55 can rotate with the wire 4. When multiple clamping assemblies are combined into an integral structure by connecting the positioning steel strip 52 and the anti-collision member 51, the release of rotational torque between the wire 4 and the guide plate 1 is not affected, and the position of the anti-collision member 51 will not change due to the rotation of the wire 4.

[0026] In this embodiment, the limiting and fixing sleeve 54 has a circumferential groove on its outer side, and the rotating positioning sleeve 55 has a circumferential slider on its inner side that matches the circumferential groove. Relative rotation is achieved through the sliding engagement between the circumferential slider and the circumferential groove.

[0027] In this embodiment, a plurality of bearing balls 56 are circumferentially arranged between the two sides of the circumferential groove and the side of the circumferential slider; a plurality of needle rollers 57 are circumferentially arranged between the bottom surface of the circumferential groove and the opposite surface of the circumferential slider. The mutual cooperation of the bearing balls 56 and the needle rollers 57, similar to a needle roller ball bearing, is used to reduce friction.

[0028] In this embodiment, one side of the circumferential groove is a positioning ring 58, which is detachably sleeved on the limiting fixing sleeve 54. The detachably connected positioning ring 58 facilitates the assembly and disassembly of the clamping component. After the positioning ring 58 is installed in place, it can be fixed by screws and the limiting fixing sleeve 54.

[0029] In this embodiment, the upper outer side of the circumferential slider has a protrusion with bolt holes 59; the protrusion is connected to the edge of the anti-collision member 51 by bolts 53.

[0030] Specific working principle: At the rear end of the guide plate 1, a wire anti-torsion rotator 3 and a wire 4 are connected, at which point the counterweight 2 is in a naturally extended downward state; a clamping assembly is installed on the wire 4 at the rear end of the anti-torsion rotator, such as... Figure 5 As shown; the center of the anti-collision component 51 is adjusted by the clamping assembly.

[0031] Since the rotating positioning sleeve 55 and the limiting fixing sleeve 54 are only for clamping and positioning, and the rotating positioning sleeve 55 has a needle roller 57 and a double-sided ball, such as Figure 6As shown, the rotating positioning sleeve 55 on the conductor 4 can rotate with the conductor 4. When multiple rotating positioning sleeves 55 are connected by the positioning steel strip 52 and the anti-collision member 51 to form an integral structure, it does not affect the release of rotational torque between the conductor 4 and the guide plate 1, nor does it change the position of the anti-collision member 51 due to the rotation of the conductor 4.

[0032] When the bulletproof walkway 1 system enters the line-laying trolley, the tail hammer bounces up due to the collision with the trolley wheel. Restricted by the anti-collision component 51, it will not collide with any facilities above the trolley, thus achieving the function of protecting the relevant facilities above the trolley.

[0033] Therefore, the multi-split conductor laying board counterweight bulletproof device provided by the above solution uses the anti-collision component 51 to block the counterweight 2 when it bounces over the pulley, thus achieving a bulletproof effect. The device is easy to install and disassemble, and has a significant bulletproof effect when in use. Furthermore, due to the relative rotation between the rotating positioning sleeve 55 and the limiting fixing sleeve 54, the rotating positioning sleeve 55 can rotate with the conductor 4. When multiple clamping components are connected by the positioning steel strip 52 and the anti-collision component 51 to form an integral structure, it does not affect the release of rotational torque between the conductor 4 and the board 1, nor does it change the position of the anti-collision component 51 due to the rotation of the conductor 4.

[0034] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
