Description

Technical Field

[0001] The present invention relates to the technical field of live installation of electric power equipment, in particular to a U-shaped installation tool for facilitating the installation of a fallen-off live-line fixer. Background Art

[0002] During production, the mounting handle and insulating ceramic connection of the power link is filled with special cement or other materials into the hole of the insulating ceramic body before the mounting handle is inserted. After the power link is installed and used, as time goes by, the cement filled inside ages, causing the mounting handle and the insulating ceramic body to separate, causing the link to fall off and then causing the line to ground, posing a major safety hazard. In the existing technology, the tools for hanging the detached link are often complex in structure and require the coordination of multiple mechanisms. However, considering that in the case of live work, the operator is often far away from the live link, and the observation accuracy during use is limited. At the same time, the operator often uses a long insulating rod for operation, which is inconvenient to control the end of the long insulating rod. The relatively cumbersome operation process is not only time-consuming and labor-intensive, but also prone to safety hazards.

[0003] For example, a "type link reinforcement device" disclosed in Chinese patent literature, with publication number: CN214412198U, discloses that it includes two splints with a gap between the two splints, and a buckle for one-way locking is provided in the gap; however, this solution has too many mechanisms, is cumbersome to operate, is not convenient for long-distance use, and is prone to safety hazards. Summary of the Invention

[0004] In order to solve the problem of complex structure and inconvenient operation of the Link reinforcement device in the prior art, the present invention provides a U-shaped installation tool that is convenient for installing the live fixer of the Link that has been detached. The tool can simplify the operator's actions through the connecting parts, reduce the tediousness of the operation, and facilitate the installation of the Link reinforcement device, so that the live hanging of the Link can be safely achieved with simple operations.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A U-shaped installation tool for facilitating the installation of a detached linker live fixture comprises: an operating portion connected to a linker fixing portion for attaching a live linker; the operating portion comprising a first operating member fixedly connected to a second operating member, with a first connecting cavity and a second opening formed in sequence between the first operating member and the second operating member, the first connecting cavity being used to connect an insulating rod; and a U-shaped second opening for snapping onto the linker fixing portion. The linker fixing portion is driven by the operating portion, and the insulating rod and the linker fixing portion are connected via the second opening and the first connecting cavity, thereby facilitating operation of the linker fixing portion. The open design allows the operator to freely move the insulating rod and the operating portion, and the simple snap-fit ​​connection does not cause resistance during overall movement, thereby reducing redundant structures. The operating portion can be easily controlled, requiring only one degree of freedom movement along the opening direction to complete the connection and fixation of the operating portion. This also avoids safety risks such as misalignment caused by mutual movement of components when attaching the linker.

[0007] Preferably, a circular arc groove is provided on the front surface of the first operating member, with the opening of the circular arc groove facing the front surface of the first operating member and extending to the back surface of the first operating member. The circular arc groove is connected to the bottom surface of the first operating member, and the circular arc groove forms a side wall of the first connecting cavity. The design of the circular arc groove secures the operating rod, facilitates the positioning of the operating rod and the operating portion, reduces resistance when the operating rod moves the control portion, improves the efficiency of the operating rod moving the link fixing portion through the control portion, and facilitates the fixing and detachment of the operating rod and the control portion.

[0008] Preferably, the second operating member is a Z-shaped plate, which is divided into a front plate and a rear plate. The front plate forms a side wall of the first connecting cavity, and the rear plate and the first operating member form a second opening. By varying the distance between the Z-shaped member and the first operating member, multiple different cavities are formed, so that only two components are required to obtain two different connected cavities, which is easy to install and use, and does not require other structures for separate fixing and intermediate connection. At the same time, by forming the cavity walls of the two connected cavities at different positions on the same side of the Z-shaped plate, redundant cavity-forming structures are reduced.

[0009] Preferably, the distance between the front plate and the first operating member is greater than the distance between the rear plate and the first operating member, and the rear plate is provided with an array of fixed connection holes, through which the rear plate is connected to the first operating member. The large opening of the link fixing portion can be clamped by the front plate and the first operating member, while the insulating rod is fixed by the rear plate.

[0010] Preferably, the link fixing portion includes a first clamping member connected to a second clamping member, the first clamping member being used to clamp the crossarm, and the second clamping member being used to hang the link; an operating connection member is provided between the first clamping member and the second clamping member, the operating connection member being used to fix to the operating portion. The operating connection member is located on the first clamping member, the first clamping member and the second clamping member are fixedly connected, and the operating connection member and the second clamping member are respectively located on the upper and lower sides of the first clamping member; by arranging the first clamping member, the operating connection member, and the second clamping member in sequence from left to right, it is convenient to simultaneously control the first clamping member and the second clamping member through the operating connection member, thereby improving operational convenience and safety.

[0011] Preferably, the operating connection member includes one or more vertical plates, a fixing groove is provided at the bottom of the vertical plate, the thickness of the vertical plate is the same as the size of the opening of the second opening, and the length of the fixing groove is slightly greater than the length of the second opening. The vertical plates are arranged vertically downward, and the arrangement direction of the vertical plates is from the first clamping member to the second clamping member. When there are multiple vertical plates, the vertical plates are parallel to each other, and the two ends of the vertical plates are respectively connected to the first clamping member and the second clamping member. The fixing groove opens downward, and the fixing groove is located between the first clamping member and the second clamping member, and the depth of the fixing groove is 0-2cm; the first clamping member and the second clamping member are fixedly connected by the vertical plate, and the link fixing part is connected to the operating part through the opening on the lower side of the vertical plate. The connection and disconnection of the operating part and the link fixing part can be completed by moving with one degree of freedom, which is convenient for operation when working at a long distance and high, and avoids alignment problems caused by inconvenient observation.

[0012] Preferably, the second clamping member includes a clamping opening, and a sliding baffle is provided at the opening of the clamping opening. The movement direction of the sliding baffle is perpendicular to the opening direction of the clamping opening, and the sliding baffle is used to seal the clamping opening after sliding. The opening direction of the clamping opening is backward, and a sliding baffle is provided on the upper side of the opening of the clamping opening. The sliding baffle is used to slide up and down to close or open the clamping opening. The sliding baffle includes a sliding member and a fixing member. The fixing member is fixedly connected to the upper side end face of the clamping opening. The sliding member includes a sliding cavity formed by a hollow middle, and the sliding cavity and the fixing member slide in cooperation.

[0013] Preferably, the second clamping member includes a clamping opening, a fixed baffle disposed at the bottom of the clamping opening perpendicular to the opening direction of the clamping opening, and a fixing hook connected to the second clamping member. The fixed baffle and the vertical plate form a cross arrangement, and the fixed baffle and the clamping opening also form a cross arrangement. The fixed baffle prevents the link fixing portion from deflecting or shaking, and restricting one more degree of freedom can prevent the link fixing portion from falling. At the same time, a fixing hook is fixedly connected to the underside of the second clamping member, which is used to further secure the link fixing portion and connect it in the event of the link fixing portion falling, further improving safety.

DETAILED DESCRIPTION

[0021] The following describes the implementation methods of the present invention through specific embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0022] like Figure 1As shown, in a preferred embodiment, the present invention discloses a U-shaped installation tool that is convenient for installing a detached link live fixer, comprising: an operating portion, the operating portion is connected to a link fixing portion, the link fixing portion is used to hang the live link; the operating portion comprises a first operating member 1, the first operating member 1 is fixedly connected to a second operating member 2, a first connecting cavity 3 and a second opening 4 are formed between the first operating member 1 and the second operating member 2 in sequence, the first connecting cavity is used to connect the insulating rod; the second opening is U-shaped and is used to clamp the link fixing portion.

[0023] The front face of the first operating member 1 is provided with an arcuate groove 5, which opens toward the front face of the first operating member 1 and extends to the back face of the first operating member 1. The arcuate groove 5 connects to the bottom face of the first operating member 1 and forms one sidewall of the first connecting cavity. The second operating member 2 is a Z-shaped plate, which is divided into a front plate 6 and a rear plate 7. The front plate 6 forms one sidewall of the first connecting cavity 3, and the rear plate 7 and the first operating member 1 form a second opening 4.

[0024] During use, the insulating rod is passed through the cavity between the Z-shaped plate and the arc groove, and the second opening is clipped to the lower side of the link fixing part. The insulating rod is used to drive the link fixing part to move through the operating part. After the link fixing part is fixed to the cross arm, the insulating rod is used to fix the link fixing part to the cross arm and the link is fixed to the link fixing part. Move the operating part downward to disengage the second opening from the link fixing part.

[0025] The distance between the front plate and the first operating member is greater than the distance between the rear plate and the first operating member. The rear plate is provided with fixed connection holes arranged in an array, and the rear plate is connected to the first operating member through the fixed connection holes.

[0026] When in use, the front plate and the rear plate are arranged axially along the arc groove of the first operating member in sequence, the rear plate and the arc groove form a first cavity in the shape of a cylindrical cavity, the front plate and the first operating member form a second opening in the shape of a U-shape, and the insulating rod is inserted into the first cavity and then extends through the first cavity from the second opening.

[0027] like Figure 2As shown, the link fixing part includes a first clamping member 9, which is connected to a second clamping member 10. The first clamping member 9 is used to clamp the crossbar, and the second clamping member 10 is used to hang the link. An operating connection member is provided between the first clamping member 9 and the second clamping member 10, and the operating connection member is used to be fixed to the operating part. The operating connection member is located on the first clamping member 9, and the first clamping member 9 is fixedly connected to the second clamping member 10. The operating connection member and the second clamping member are respectively located on the upper and lower sides of the first clamping member. The first clamping member, the operating connection member and the second clamping member are arranged in sequence from left to right. The operating connection member includes one or more vertical plates 11, and a fixing groove 12 is provided at the bottom of the vertical plate 11. The thickness of the vertical plate 11 is the same as the opening size of the second opening 4, and the length of the fixing groove 12 is slightly larger than the length of the second opening 4. The vertical plate 11 is arranged vertically downward, and the arrangement direction of the vertical plate 11 is from the first clamping member 9 to the second clamping member 10. When there are multiple vertical plates 11, the vertical plates 11 are parallel to each other, and the two ends of the vertical plate are respectively connected to the first clamping member and the second clamping member. The fixing groove opens downward, and the fixing groove is located between the first clamping member and the second clamping member. The depth of the fixing groove is 0-2 cm.

[0028] When in use, the operating part is driven to engage with the fixing groove by the insulating rod, and then the insulating rod is used to drive the link fixing part to move through the operating part and the operating connecting piece; the operating part is moved upward so that the vertical plate enters the second opening, and at the same time the second opening enters the fixing groove. The fixing groove fixes the two sides of the second opening to prevent the second opening from sliding on the lower side of the vertical plate.

[0029] In the second embodiment, the second clamping member 10 includes a clamping opening 13, and a sliding block rod is provided at the opening of the clamping opening 13. The movement direction of the sliding block rod is perpendicular to the opening direction of the clamping opening, and the sliding block rod is used to slide and seal the clamping opening. The opening direction of the clamping opening is backward, and a sliding block rod is provided on the upper side of the opening of the clamping opening. The sliding block rod is used to slide up and down to close or open the clamping opening. The sliding block rod includes a sliding part and a fixed part. The fixed part is fixedly connected to the upper side end face of the clamping opening. The sliding part includes a sliding cavity formed by a hollow middle, and the sliding cavity and the fixed part slide in cooperation. When in use, the cross arm is clamped into the clamping opening. After the cross arm has fully entered the clamping opening, the end of the insulating rod is used to slide the sliding block rod. The fixed part slides in the sliding cavity, and the fixed block rod moves downward to cover the clamping opening. The rear end face of the cross arm abuts against the fixed block rod to fix the cross arm.

[0030] In a third embodiment, the second clamping member includes a clamping opening, a fixed baffle disposed at the bottom of the clamping opening, perpendicular to the opening direction of the clamping opening, and a fixing hook connected to the second clamping member. The fixed baffle and the vertical plate form a cross arrangement, and the fixed baffle and the clamping opening also form a cross arrangement. During use, the clamping opening is moved to the crossarm, and the crossarm is snapped into the clamping opening. The vertical baffle then abuts against the front end of the crossarm, preventing the second clamping member from swinging, and snapping the fixing hook into place with the vertical surface of the crossarm below the clamping opening.

[0031] In a fourth embodiment, the rear plate is provided with a rear plate disassembly mechanism corresponding to the fixed connection hole. The rear plate disassembly mechanism is connected to the fixed connection hole. The rear plate disassembly mechanism is used to connect or disconnect the rear plate and the first operating member, and to increase or decrease the distance between the second operating member, the rear plate, and the first operating member, so as to facilitate the removal or installation of the insulating rod. The rear plate disassembly mechanism includes a triangular protrusion, the height of the triangular protrusion increases from left to right, and meshing teeth and grooves are provided between the triangular protrusion and the insulating rod. The fixed connection hole is connected to a fixed pin, and a return spring is provided on the outside of the fixed pin. The return spring is used to return the first operating member to its original position. The operating part can be disassembled and assembled at any time through the rear plate disassembly mechanism during hanging, which facilitates the operation of the insulating rod to perform other actions. At the same time, its rotating design prevents accidental disassembly during hanging. At the same time, it can change the size of the gap between the two parts of the operating part to achieve its clamping and loosening of the link fixed part.

[0032] During use, when the link fixing portion is fixed to the crossarm and the insulating rod needs to be removed for other operations, the insulating rod is rotated, and the meshing portion of the insulating rod and the triangular protrusion moves, causing the insulating rod to move from a position with a small gap to a position with a large gap, thereby increasing the opening and the gap between the first operating member and the second operating member. The insulating rod is then moved downward to remove the insulating rod together with the operating member. When the operating member needs to clamp the link fixing portion, the insulating rod is rotated, and the meshing portion of the insulating rod and the triangular protrusion moves, causing the insulating rod to move from a position with a large gap to a position with a small gap, thereby reducing the gap and the opening distance between the first operating member and the second operating member, thereby clamping the link fixing portion and the insulating rod, and at the same time shortening the return spring.

[0033] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
