Description

Technical Field

[0001] This application relates to the technical field of cable wiring, and more specifically, to a cable wiring device for a 10 kV line. Background Art

[0002] An aerial cable is supported by utility poles and erected in the air above the driving track of a power-driven vehicle. It is a special form of transmission line that directly supplies power to the vehicle when making contact connection. When an aerial cable is damaged and needs to be repaired or installed, two aerial cables need to be wired together, making it laborious for a single person to lock and work on the two aerial cables.

[0003] The prior art document with the publication (announcement) number CN117526161A provides an auxiliary wiring device for aerial cables. In the related technology of this device, two aerial cables to be wired are respectively inserted into the openings, and then the turntable two is rotated. The rotation of the turntable two drives the screw rod to rotate, and the rotation of the screw rod drives the pressure rod to move up and down under the limiting action of the avoidance opening. The downward movement of the pressure rod exerts pressure on the rotating swing rod, causing the rotating swing rod to swing in a circular motion with the center of the fixed disk as the origin. The swinging of the rotating swing rod drives the rotating base to rotate, and the rotation of the rotating base causes the limiting frames to swing with the connection point with the sliding opening as the center. At the same time, the limiting frames rotate and slide inside the sliding opening. Through the swinging of the limiting frames, the clamping ends of the limiting frames can move away from or close to the center of the fixed disk. The right side can clamp cables of various sizes and can be quickly locked, thus assisting in the wiring work.

[0004] Although the above prior art solution can achieve relevant beneficial effects through the structure of the prior art, there are still the following defects: when the clamping mechanism clamps and fixes the overhead cable, the clamping response is relatively slow, and the wiring efficiency is low.

[0005] In view of this, we propose a cable wiring device for a 10 kV line. Summary of the Utility Model

[0006] To improve the problems proposed in the above background art, this application provides a cable wiring device for a 10 kV line.

[0007] The cable wiring device for a 10 kV line provided by this application adopts the following technical solutions:

[0008] A cable wiring device for a 10 kV line includes:

[0009] A sleeve holder;

[0010] A pull plate holder, symmetrically and slidably connected to the inclined groove of the sleeve holder;

[0011] A screw tightener, hinged and installed between the two pull plate holders;

[0012] The connecting rod is hingedly installed at the other end of the pull plate frame;

[0013] The wire pressing plate for pressing and limiting the cable is installed between the pull plate frame and the sleeve frame in a linear equidistant structure by hinge.

[0014] By adopting the above technical solution, the screw tightener is used for limiting and shrinking, and the two pull plate frames installed by hinge are pulled to move relatively closer along the inclined groove of the sleeve frame, so that the displaced pull plate frame drives the connecting rod installed by hinge to pull the wire pressing plate to limit and turn over, quickly pressing and limiting the cable inserted into the wire groove of the sleeve frame, thereby improving the convenience of cable butt joint installation.

[0015] As an alternative solution of the technical solution of this application document, the whole sleeve frame is a U-shaped structure made of aluminum alloy material, and an anti-detachment groove in an inverted hook structure is arranged in the wire groove of the sleeve frame.

[0016] By adopting the above technical solution, the U-shaped sleeve frame made of aluminum alloy material can ensure that the sleeve frame has a certain service strength and a relatively light carrying mass, while the anti-detachment groove in an inverted hook structure is convenient for ensuring that the cable closely attached to the wire groove of the sleeve frame under the pressing and limiting of the wire pressing plate is more stable and not easy to fall off.

[0017] As an alternative solution of the technical solution of this application document, a through hole is arranged at one end of the sleeve frame, a wire transmission wheel is rotatably connected in the through hole, and the wire transmission wheel is rotationally limited to the sleeve frame through a ratchet structure.

[0018] By adopting the above technical solution, the wire transmission wheel that realizes one-way rotation through the ratchet structure can roll and transmit the cable pressed in the wire groove of the sleeve frame, thereby changing the wiring length requirement between the cables to be connected.

[0019] As an alternative solution of the technical solution of this application document, a wire pressing arc plate is hingedly installed on one side of the wire pressing plate. The wire pressing arc plate is elastically connected and limited to the movable groove through an elastic rod, and a rubber layer is pasted on the outside of the wire pressing arc plate.

[0020] By adopting the above technical solution, the wire pressing arc plate is elastically hinged in the movable groove of the wire pressing plate through the elastic rod, so that the elastically limited wire pressing arc plate can prevent the pressed cable from being unhooked unidirectionally.

[0021] As an alternative solution of the technical solution of this application document, the elastic rod is composed of a column cylinder, a column rod and a spring member. The column rod is sleeved inside the column cylinder and is in sliding limit contact with the inner groove of the wire pressing arc plate. The column cylinder is threadedly connected to the screw hole opened outside the wire pressing plate and is sleeved outside the spring member.

[0022] By adopting the above technical solution, a resilient rod is composed of a cylinder, a column rod and a spring member, so that when the limiting thread of the cylinder is screwed in and adjusted, the elastic strength of the resilient rod can be changed.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. In the present application, by using the limiting contraction of the screw tightener to drive the two pull plate frames installed by hinges to move relatively closer along the inclined groove of the sleeve frame, the displaced pull plate frame drives the connecting rod installed by the hinge to pull the wire pressing plate to be limited and turned over, so as to quickly press and limit the cable inserted into the wire groove of the sleeve frame, thereby improving the convenience of cable butt joint installation.

[0025] 2. In the present application, by using the ratchet structure, the wire transmission wheel that rotates unidirectionally can roll and transmit the cable pressed in the wire groove of the sleeve frame, thereby changing the wiring length requirement between the cables to be connected.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0033] Referring to Figures 1-5 , a 10kV line cable connection device described in the embodiment of the present application, includes:

[0034] Casing rack 1;

[0035] Pulling plate rack 2, symmetrically structured and slidably connected in the inclined groove of the casing rack 1;

[0036] Screw tightener 3, hingedly installed between the two pulling plate racks 2;

[0037] Connecting rod 4, hingedly installed at the other end of the pulling plate rack 2;

[0038] Pressing plate 5 for pressing and limiting the cable, linearly and equidistantly structured and hingedly installed between the pulling plate rack 2 and the casing rack 1.

[0039] The 10kV line cable connection device, by using the screw tightener 3 for limiting and contracting, pulls the two hingedly installed pulling plate racks 2 to move relatively closer along the inclined groove of the casing rack 1, so that the displaced pulling plate rack 2 drives the hingedly installed connecting rod 4 to pull the pressing plate 5 to limit and flip, quickly pressing and limiting the cable inserted into the wire groove of the casing rack 1, thereby improving the convenience of cable butt joint installation.

[0040] Refer to Figure 3 and Figure 2 In the 10kV line cable connection device described in the embodiment of the present application, the whole casing rack 1 is made of an aluminum alloy material in a U-shaped structure, and an anti-detachment groove in an inverted hook structure is provided in the wire groove of the casing rack 1. A through hole is provided at one end of the casing rack 1, and a wire transmission wheel 11 is rotatably connected in the through hole, and the wire transmission wheel 11 is rotationally limited to the casing rack 1 through a ratchet structure.

[0041] The 10kV line cable connection device, by using the U-shaped structure casing rack 1 made of aluminum alloy material, can ensure that the casing rack 1 has a certain service strength and a relatively light carrying mass. The anti-detachment groove in an inverted hook structure is convenient for ensuring that the cable closely attached to the wire groove of the casing rack 1 under the pressing and limiting of the pressing plate 5 is more stable and not easy to fall off. The wire transmission wheel 11 with a one-way rotation realized by the ratchet structure can roll and transmit the cable pressed in the wire groove of the casing rack 1, thereby changing the wiring length requirement between the cables to be connected.

[0042] Refer to Figure 4 and Figure 1 In the 10kV line cable connection device described in the embodiment of the present application, an activity groove is provided at one end of the pressing plate 5, and a pressing arc plate 51 is hingedly installed in the activity groove. The pressing arc plate 51 is elastically connected and limited to the activity groove through an elastic rod 52, and a rubber layer is pasted on the outside of the pressing arc plate 51.

[0043] The 10kV line cable connection device, by using the elastic rod 52 to elastically hinge the pressing arc plate 51 in the activity groove of the pressing plate 5, enables the elastically limited pressing arc plate 51 to have a one-way anti-unhooking effect on the pressed cable.

[0044] Refer toFigure 5 and Figure 4 In the 10kV line cable connection device recorded in the embodiment of the present application, the elastic rod 52 is composed of three parts: a column tube 53, a column rod 54 and a spring member 55. The column rod 54 is sleeved inside the column tube 53 and slides against the inner groove of the wire pressing arc plate 51 to limit the position. The column tube 53 is threadedly connected to the screw hole opened on the outside of the wire pressing plate 5 and sleeved on the outside of the spring member 55.

[0045] The 10kV line cable connection device comprises a column 53, a column rod 54 and a spring member 55 to form an elastic rod 52, so that when the column 53 is screwed in and adjusted, the elastic strength of the elastic rod 52 can be changed.

[0046] Working principle: First, insert the two cables to be connected into the cable duct of the casing rack 1 respectively, and reserve a suitable length of cable for connection;

[0047] At this time, the wire pressing arc plate 51 elastically supported by the elastic rod 52 elastically presses the surface of the inserted cable, and makes the cable and the anti-slip groove with an inverted hook structure to prevent slipping and limit position;

[0048] Then, the screw tightener 3 is manually rotated, and the shortened screw tightener 3 pulls the two pull plate frames 2 to retract and move closer along the inclined groove track of the casing frame 1. The displaced pull plate frame 2 drives the hinged connecting rod 4 to pull the wire pressing plate 5 to limit and flip, so as to quickly press and limit the cable inserted into the wire groove of the casing frame 1, and enhance the pressing and fixing of the wire pressing arc plate 51 on the inserted cables.
