Description

Technical Field

[0001] The invention relates to the technical field of power connection tools, in particular to a low-voltage overhead line quick access connector. Background Art

[0002] Power lines with a rated voltage of 1kV or less. Low-voltage lines include low-voltage overhead lines, low-voltage overhead insulated lines, low-voltage cable lines and indoor distribution lines, which are used to directly transmit electrical energy to low-voltage electrical equipment and are an important part of the low-voltage distribution system (see low-voltage distribution).

[0003] In areas with complex and harsh terrain such as high mountains and ridges, dense vegetation, etc., where the terrain is complex, transportation is inconvenient, road construction is difficult, and helicopter transportation is too expensive, freight ropeway transportation is the inevitable choice for sand, gravel, tower materials, and material transportation. When setting up freight ropeways, the electricity usually used is taken from the nearby low-voltage overhead line through the line access device. It is necessary to connect the lead cable (such as Fig. 9 The power is obtained by connecting the power cable to the low-voltage overhead line (as shown in the figure) for power supply.

[0004] In the prior art, a quick-connect line connector provided by publication number CN113708104B includes a connection device, an accommodation space formed inside the connection device, a bearing shell, a cover connected to the bearing shell, a first line connector and a second line connector symmetrically arranged on both sides of the bearing shell, and a branch line connection fixing member connected to the first line connector and the second line connector respectively. The beneficial effect of the prior art is that by pre-fixing the line, the four lines can be quickly connected and fixed in pairs by plugging, the connection is tight and stable, and the disassembly is quick and convenient, and the connection and disconnection of the line can be controlled at any time to ensure the safety of the staff.

[0005] The above-mentioned prior art is to connect and fix the four lines in pairs. This method results in many operating steps when connecting the cables, which affects the access efficiency. Moreover, the above-mentioned prior art can only be used for the connection between the ends of two cables. However, when one cable needs to be overlapped on another cable, this method cannot be achieved, making the cable connection method not comprehensive.

[0035] The following is combined with Figure 1-Figure 9 The present invention is described in further detail.

[0036] The embodiment of the present invention discloses a low-voltage overhead line quick access connector, which can quickly connect a lead-in cable with a transmission cable, thereby making it more convenient to obtain electricity during the construction process of erecting a freight ropeway.

[0037] Reference Figure 1 and Fig. 9 A low-voltage overhead line quick access connector comprises a first connecting hinge 5, two leaves of the first connecting hinge 5 are fixedly connected with a U-shaped cover plate 1, the two U-shaped cover plates 1 are distributed up and down, the inner sides of the two U-shaped cover plates 1 are fixedly connected with a fixed mounting plate 3, a second connecting hinge 6 is fixedly connected between the two mounting plates 3, the fixed mounting plate 3 is provided with two left-right symmetrical clamping mechanisms 2 for clamping power transmission cables, an adjustment mechanism 8 for assisting in adjusting the clamping mechanism 2 to adapt to the cable diameter is provided on the fixed mounting plate 3 and between the two clamping mechanisms 2, two left-right symmetrical support frames 7 are fixedly connected to the rear side of the upper surface of the fixed mounting plate 3 on the lower U-shaped cover plate 1, and a power taking mechanism 4 connected to the lead-in cable is provided on the lower surface of the lower U-shaped cover plate 1.

[0038] Reference Figure 2 Taking the clamping mechanism 2 on the right side as an example, the clamping mechanism 2 includes a clamping member 22 arranged on the rear surface of the upper fixed mounting plate 3, a pushing member 21 is arranged on the front surface of the upper fixed mounting plate 3, and connecting ear plates are arranged on the upper and lower fixed mounting plates 3. The two fixed mounting plates 3 rotate in a direction approaching each other, and the fastening bolts clamp the pushing members 21 on the two fixed mounting plates 3 and fasten them to the power transmission cable through the connecting ear plates on the fixed mounting plates 3.

[0039] Reference Figure 3 and Figure 4 The pushing member 21 includes a connecting block 212 fixedly connected to the front surface of the fixed mounting plate 3, a semicircular slot is provided on the front side of the connecting block 212, two arc-shaped clamping plates 213 which are symmetrical up and down and can move radially are provided inside the semicircular slot, a rubber pad 214 is fixedly connected to the side of the arc-shaped clamping plate 213 close to the center of the connecting block 212, a plurality of evenly distributed connecting push rods 211 are elastically slidable radially on the side of the arc-shaped clamping plate 213 away from the center of the connecting block 212, and a ball 215 is rotatably connected to the end of the connecting push rod 211 away from the arc-shaped clamping plate 213.

[0040] During specific use, first, according to the diameter of the transmission cable, the adjustment mechanism 8 adjusts the distance between the arc-shaped clamping plates 213 and the connecting block 212 on the two fixed mounting plates 3 through the clamping piece 22. After the adjustment is completed, first, take out a section of insulation layer of suitable length at the power-taking position of the transmission cable, first open the two U-shaped cover plates 1, and cooperate with the setting of the two support frames 7 to make the two U-shaped cover plates 1 open to a mutually perpendicular state, first fit the arc-shaped clamping plate 213 on the lower U-shaped cover plate 1 on the insulation layer of the transmission cable, and then rotate the upper U-shaped cover plate 1 toward the direction close to the lower U-shaped cover plate 1 until the arc-shaped clamping plate 213 on the upper U-shaped cover plate 1 fits on the insulation layer of the transmission cable. At this time, the two U-shaped cover plates 1 are parallel to each other, and the two connecting blocks 212 are distributed up and down and fit together, and the semicircular grooves thereon form a complete circle, wrapping the transmission cable therein.

[0041] When the two arc-shaped clamping plates 213 are both attached to the transmission cable, the fastening bolts are screwed onto the connecting ear plates on the two fixed mounting plates 3 to clamp the connecting blocks 212 on the two fixed mounting plates 3 to each other. The connecting blocks 212 are subjected to force on the transmission cable through the arc-shaped clamping plates 213 to clamp the transmission cable between the two connecting blocks 212. By setting the rubber pads 214, the arc-shaped clamping plates 213 and the transmission cable can be clamped more firmly after being clamped on the transmission cable.

[0042] Reference Figure 3 The clamping member 22 includes two left-right symmetrical support seats 223 fixedly connected to the rear surface of the fixed mounting plate 3. The upper and lower ends of the support seats 223 are elastically slidably connected with connecting rods 222. The front surfaces of the two left-right connecting rods 222 are commonly fixedly connected with a pushing block 221. The front surface of the pushing block 221 is an inclined surface. The inclined surface of the pushing block 221 is adapted to the position of the ball 215 and is slidably connected.

[0043] Reference Figure 3 and Figure 5 Taking the rear side adjustment mechanism 8 as an example, the rear side adjustment mechanism 8 includes a limit member 84 arranged on the fixed mounting plate 3, and an adjustment member 83 is arranged on the limit member 84. Two groups of left-right symmetrical guide wheels 82 are fixedly connected on the fixed mounting plate and located on both sides of the adjustment member 83. The number of guide wheels in each group 82 is three and they are distributed in a herringbone shape in the left and right directions.

[0044] Reference Figure 5The adjusting member 83 includes a winding drum 831 fixedly connected to the limiting member 84, and two centrally symmetrical connecting ear blocks 833 are fixedly connected to the circumferential surface of the winding drum 831. A pull rope 832 is fixedly connected to the connecting ear block 833. The end of the pull rope 832 away from the connecting ear block 833 is Y-shaped and the two ends of the Y-shape are respectively fixedly connected to the pulling block 81 passing through the corresponding guide wheel 82. The pulling block 81 is fixedly connected to its corresponding pushing block 221, and the end of the winding drum 831 away from the fixed mounting plate 3 passes through the U-shaped cover plate 1.

[0045] In specific use, when the adjustment mechanism 8 adjusts the distance between the arc-shaped clamping plate 213 and the connecting block 212 through the clamping member 22, the staff first cancels the limit of the winding drum 831 on the fixed mounting plate 3 through the limit member 84, and then rotates the winding drum 831. The winding drum 831 pulls the pull rope 832 through the connecting ear block 833 to wrap around the outer circumference of the winding drum 831. The winding drum 831 bypasses multiple guide wheels 82 and generates a pulling force on the pushing block 221 through the pull rope 832 in cooperation with the pulling block 81, thereby driving the support The two pushing blocks 221 on both sides of the seat 223 move towards each other and shrink the clamping member 22 to the inside of the supporting seat 223. When the pushing block 221 slides, the inclined surface of the pushing block 221 slides against the ball 215 on the connecting push rod 211, and the pushing block 221 gradually generates a reverse thrust on the ball 215, so that the connecting push rod 211 moves towards the center of the semicircular groove on the pushing block 221, thereby adjusting the distance between the arc clamping plate 213 and the connecting block 212 to adapt to the diameter of the transmission cable.

[0046] Reference Figure 5 and Figure 6 The limiting member 84 includes a turntable 842 embedded and rotatably connected to the rear surface of the fixed mounting plate 3, a connecting shaft 844 is arranged between the turntable 842 and the fixed mounting plate 3, a connecting cylinder 843 is fixedly connected to the rear surface of the turntable 842, the upper surface of the connecting cylinder 843 elastically slides and penetrates and connects with the limiting pin 841, a handle is arranged at the rear end of the limiting pin 841, and the front end of the limiting pin 841 penetrates to the front surface of the turntable 842, a groove adapted to the turntable 842 is arranged on the fixed mounting plate 3, and a plurality of limiting holes 845 are arranged in a circular array inside the groove, and the position of the limiting hole 845 corresponds to the position of the limiting pin 841 and is snap-fitted.

[0047] When the position limit of the take-up drum 831 on the fixed mounting plate 3 is cancelled by the position limit member 84, the position limit pin 841 is first pulled upward inside the connecting tube 843 by the handle at the top of the position limit pin 841. At this time, the bottom end of the position limit pin 841 is pulled out from the position limit hole 845. The position limit pin 841 no longer limits the turntable 842 on the fixed mounting plate 3. The turntable 842 can be freely rotated on the fixed mounting plate 3 by cooperating with the connecting shaft 844. At this time, the take-up drum 831 can be rotated freely by rotating the take-up drum 831. 31 is used to adjust the position of the arc-shaped clamping plate 213. When the adjustment is completed, the pulling force on the limit pin 841 is cancelled. Since the limit pin 841 and the turntable 842 are elastically slidably connected, when the limit pin 841 is no longer subjected to the upward pulling force, the limit pin 841 returns to its original position on the turntable 842, passes through the turntable 842 and is re-engaged in the limit hole 845, thereby limiting the turntable 842 on the fixed mounting plate 3 again, so that the arc-shaped clamping plate 213 remains stationary after the position adjustment is completed.

[0048] Reference Figure 7 The power-taking mechanism 4 includes a mounting seat 42 fixedly connected to the lower surface of the U-shaped cover plate 1 below, and a connector 43 for connecting to the power cable is provided on the mounting seat 42. An adapter 41 for taking power from the power transmission cable is provided on the upper surface of the fixed mounting plate 3, and an adapter 41 is also provided on the front surface of the upper fixed mounting plate 3.

[0049] Reference Figure 8 The adapter 41 includes a fixed box 412 fixedly connected to the fixed mounting plate 3, a connecting plate 413 is fixedly connected to the inner wall of the bottom end of the fixed box 412, a plurality of evenly distributed mounting tubes 414 are fixedly connected to the upper surface of the connecting plate 413, the upper surface of the mounting tube 414 elastically slides up and down and is penetrated by a connecting contact rod 411, and the top end of the connecting contact rod 411 penetrates to the outside of the fixed box 412.

[0050] Reference Figure 8The lower surface of the mounting seat 42 is provided with a mounting cavity, the connecting member 43 includes an L-shaped mounting plate 434 fixedly connected to the mounting cavity of the mounting seat 42, a clamping joint 433 is fixedly connected to the vertical section of the L-shaped mounting plate 434, an adjusting screw 431 is threadedly connected to the front surface of the mounting seat 42, the rear end of the adjusting screw 431 passes through the interior of the mounting seat 42 and is fixedly connected to an extrusion cylinder 432, the inner diameter of the extrusion cylinder 432 is adapted to the outer diameter of the clamping joint 433, and the L-shaped mounting plate 434 is fixedly connected to the mounting cavity of the mounting seat 42. Conductive rods 435 are fixedly connected to the four corners of the upper surface of the horizontal section 34. The conductive rods 435 penetrate to the outside of the mounting seat 42 and penetrate the bottom surface of the fixed box 412 and are fixedly connected to the lower surface of the connecting plate 413. An insulating sleeve 436 is sleeved on the outer surface of the conductive rod 435 and is located between the fixed box 412 and the mounting seat 42. The bottom end of the insulating sleeve 436 is fixedly connected to the mounting seat 42, and the top end of the insulating sleeve 436 penetrates the fixed mounting plate 3 and is fixedly connected to the lower surface of the fixed box 412.

[0051] During specific use, after the two arc-shaped clamping plates 213 wrap up the transmission cable, the connecting contact rods 411 on the upper and lower fixing boxes 412 are both in contact with the exposed wires of the transmission cable, and the connecting contact rods 411 are extended and retracted on the mounting tube 414. Since the wires of the transmission cable are cylindrical, the connecting contact rods 411 at different contact positions with the wires of the transmission cable shrink to different distances inside the adapter 41. Multiple connecting contact rods 411 can be more closely in contact with the wires of the transmission cable to facilitate subsequent power transmission. At the same time, the mounting tube 414 below makes the L-shaped mounting plate 434 and the wires of the transmission cable in a passage state through the connecting plate 413 and the conductive rod 435, and the connecting nose sleeve on the lead cable is set on the clamping joint 433, and then the extrusion tube 432 is pushed close to the clamping joint 433 by rotating the adjusting screw 431, and the connecting nose of the lead cable is clamped on the L-shaped mounting plate 434, so that the lead cable and the transmission cable are in a passage state.

[0052] When it is no longer necessary to draw power from the transmission cable, first remove the fastening bolts on the connecting ear plate on the fixed mounting plate 3, and then open the U-shaped cover 1. At this time, the two connecting blocks 212 are separated synchronously, and then the connecting block 212 is removed from the transmission cable, which is convenient for the staff's operation. At the same time, the exposed wire position of the transmission cable is insulated. When it is necessary to draw power again, repeat the above steps to draw power again.

[0053] Therefore, the present invention can be used for quick connection of power transmission cables of different specifications. Specifically, the power transmission cable is wrapped by two support seats 223, and the power transmission cable is clamped inside the two support seats 223 with the arc-shaped clamping plate 213 to complete the fixation on the power transmission cable. At the same time, the present invention can be provided on the clamping joint 433 by the connecting nose sleeve of the lead-in cable, and the connecting nose of the lead-in cable is pressed onto the clamping joint 433 with the extrusion cylinder 432 to complete the connection between the lead-in cable and the transmission cable. Before pressing, the deflection angle between the lead-in cable and the mounting seat 42 can be freely adjusted according to the traction direction of the lead-in cable, so that the traction force of the lead-in cable directly acts on the clamping joint 433 through the connecting nose sleeve, thereby avoiding the situation that the inclination direction of the connecting nose sleeve is inconsistent with the migration direction, causing the connecting nose sleeve to be damaged, resulting in the fall-off of the lead-in cable, and further improving the scope of application of the present invention.

[0054] The implementation principle of the present invention is:

[0055] (1) First, open the two U-shaped covers 1. With the arrangement of the two support frames 7, the two U-shaped covers 1 can be opened to a mutually perpendicular state. At this time, remove a suitable length of the insulation layer on the transmission cable to expose the wires, and align the power extraction mechanism 4 with the exposed position of the wires.

[0056] (2) Then, the clamping mechanism 2 is adjusted to match the diameter of the transmission cable through the adjustment mechanism 8 according to the diameter of the transmission cable, and then the lower pushing member 21 is first fitted under the outer circumference of the transmission cable, and at the same time, the adapter 41 is also fitted to the exposed position of the transmission cable conductor.

[0057] (3) At this time, the upper fixed mounting plate 3 is rotated in cooperation with the first connecting hinge 5 to move the pushing member 21 on the upper fixed mounting plate 3 toward the pushing member 21 on the lower fixed mounting plate 3, so that the pushing members 21 are clamped on both the upper and lower sides of the outer surface of the power transmission cable.

[0058] (4) Finally, the connecting ear plates on the two fixed mounting plates 3 are connected together by tightening bolts. At this time, the two adapters 41 are both fitted together with the exposed wires on the transmission cable, and the lead cable is connected to the inside of the mounting cavity of the mounting seat 42 through the adapter 41.

[0059] (5) When the power supply work is completed and no longer needed, first remove the fastening bolts on the two connecting ear plates, and then open the two fixed mounting plates 3 in conjunction with the first connecting hinge 5. At this time, the fixed mounting plates 3 can be quickly removed from the transmission cable, and the exposed wire positions on the transmission cable are insulated.

[0060] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
