Live working current-carrying line tightening equipment and tightening method

Abstract

The present invention relates to the technical field of live working equipment for power grid lines, specifically a live working current-carrying wire tightening device and a tightening method. The live working current-carrying wire tightening device includes a notch and a wiring clip formed at the bottom end of the mounting frame. A support plate and a fixed block are fixedly connected to the mounting frame. A placement groove is formed in the mounting frame. A rotating frame is rotatably connected to the fixed block. By providing an adjustment mechanism, rotating the rotating disc can drive the threaded rod inside the cavity to rotate. The moving block threaded on the threaded rod will move upward, thereby driving the connecting rod and the rack to move upward. When the rack moves upward through the meshing of the same gears, it drives the gear to rotate, thereby causing the entire mounting frame to rotate. At this time, the angle of the mounting frame can be adjusted to reduce the overall length of the mounting frame, so that the mounting frame will not touch other cable lines when passing through the power grid.

[0004] However, for a live fastening drainage line clamp auxiliary tool in the above technology, the angle can only be adjusted by the rotation of the fastener on the adjustment member, but the overall length of the adjustment member is fixed. In some places where the cable lines are relatively dense, it is easy to touch other cables during the process of passing through the power grid, thus causing inconvenience. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a live working drainage line fastening device to solve the problem that a live fastening drainage line clamp auxiliary tool in the above technology can only adjust the angle by the rotation of the fastener on the adjustment member, but the overall length of the adjustment member is fixed. In some places where the cable lines are relatively dense, it is easy to touch other cables during the process of passing through the power grid, thus causing inconvenience.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: It includes a mounting frame and a wiring clip; a notch is provided at the bottom end of the mounting frame, a support plate and a fixed block are fixedly connected to the mounting frame, a placement groove is provided on the mounting frame, a rotating frame is rotatably connected to the fixed block, a top block is rotatably connected to the rotating frame, the top block abuts against the fixed frame, a screw rod is threadedly connected to the fixed frame, a top rod is rotatably connected to the bottom end of the screw rod, a buckle is fixedly connected to the top end of the top rod, an adjusting mechanism is provided on the front end of the mounting frame, the adjusting mechanism includes a convex block, the convex block is fixedly connected to the mounting frame, a gear is fixedly connected inside the convex block, the convex block is rotatably connected to a fixed column, the fixed column is fixedly connected to the top end of a fixed rod, the gear meshes with a rack, the bottom end of the rack is fixedly connected to a connecting rod, the rack and the connecting rod are respectively slidably connected inside a first sliding groove and a second sliding groove, the bottom end of the connecting rod is fixedly connected to a moving block, the moving block is threadedly connected to a threaded rod, the top end of the threaded rod is rotatably connected to the inner wall of a cavity, the first sliding groove, the second sliding groove and the cavity are all provided inside the fixed rod, a through groove is provided on the inner wall of the second sliding groove, a connecting member is fixedly connected to the bottom end of the threaded rod, a disc is fixedly connected to the bottom end of the connecting member, and a protection mechanism is provided on the disc.

[0007] Further, the protection mechanism includes two pressing blocks, a first spring and an inserting column are fixedly connected to the pressing block, the inserting column is aligned with a slot, the slots are provided on the left and right sides of the disc, the disc is rotatably connected inside a chamber, the side of the first spring away from the pressing block is fixedly connected to the inner wall of a sliding groove, the sliding grooves are provided on the left and right sides of a rotating plate, the rotating plate is rotatably connected to a first connecting seat, the top end of the first connecting seat is fixedly connected to the bottom end of the fixed rod, and a fixing mechanism is provided at the bottom end of the disc.

[0008] The beneficial effect of adopting the above further scheme is that by setting the protection mechanism, the function of protecting the disc is realized. Only by pressing the pressing block inward first to make the inserting column fixed on the pressing block insert into the slot, and then when rotating the rotating plate, the disc can be driven to rotate together through the abutment of the inserting column and the slot, ensuring that the disc will not rotate due to accidental contact with the rotating plate. The first spring is used to reset the pressing block.

[0009] Further, the fixing mechanism includes a ratchet wheel which is rotatably connected inside a rotating cavity. The rotating cavity is formed inside a second connecting seat, and the top of the second connecting seat is fixedly connected to a rotating plate. The ratchet wheel is engaged with a ratchet pawl. A support rod is fixedly connected to the ratchet pawl. A second spring is fixedly connected to the side of the support rod away from the ratchet pawl, and the side of the second spring away from the support rod is fixedly connected to the inner wall of a long groove which is formed inside the rotating cavity. A torsion spring is sleeved on the bottom end of the ratchet pawl, the top end of the ratchet pawl is fixedly connected to the bottom end of a special-shaped rod, and the top end of the special-shaped rod is fixedly connected to one side of a pressing block.

[0010] The beneficial effect of adopting the above further scheme is that the ratchet wheel is connected to the disc, and the ratchet wheel is fixed by engaging with two groups of ratchet pawls. At this time, the ratchet wheel cannot rotate clockwise. By setting the helix direction of the threaded rod, only when the threaded rod rotates clockwise can the moving block threadedly connected to the threaded rod move upward. At this time, the connecting piece and the ratchet wheel will be fixed together and cannot rotate, so as to prevent the rack from moving upward under the action of gravity. A torsion spring is sleeved on the bottom end of the ratchet pawl to facilitate the ratchet pawl to keep in contact with the ratchet wheel. A support rod is also fixedly connected to the ratchet pawl, and a second spring is fixedly connected to the support rod to support and reset the support rod.

[0011] Further, a connecting block is fixedly connected to the top end of the rotating plate, and the connecting block is rotatably connected inside a first connecting seat.

[0012] The beneficial effect of adopting the above further scheme is that a connecting block is fixed to the top end of the rotating plate. The connecting block is rotatably connected inside the first connecting seat, and a rotating groove corresponding to the connecting block is formed inside the first connecting seat. The connecting block is designed in a T shape to connect the rotating plate and the first connecting seat together and ensure normal rotation between the rotating plate and the first connecting seat.

[0013] Further, clamping blocks are fixedly connected to the left and right sides of the rack and the connecting rod, and the clamping blocks are slidably connected to clamping grooves which are formed on the inner walls of a first sliding groove and a second sliding groove.

[0014] The beneficial effect of adopting the above further scheme is that during the process of the moving block driving the connecting rod to move upward, the rack and the connecting rod will slide in the first sliding groove and the second sliding groove respectively. At this time, the clamping blocks fixed on the rack and the connecting rod will slide along the clamping grooves. Through the contact between the clamping blocks and the inner walls of the clamping grooves, the stability of the rack and the connecting rod during the moving process is improved.

[0015] Further, an abutting block is fixedly connected to the bottom end of the rack, and the abutting block abuts against the inner wall of the first sliding groove.

[0016] The beneficial effect of adopting the above further scheme is that an abutment block is fixed on the bottom end of the rack. In the initial state, the abutment block will abut against the bottom end of the inner wall of the first slide groove, so that the rack and the connecting rod cannot move downward, thereby ensuring that the mounting frame can only rotate counterclockwise in a single direction.

[0017] Furthermore, a circular groove is formed at the rear end of the moving block, a column is inserted into the circular groove, and the top and bottom ends of the column are fixedly connected to the inner wall of the cavity.

[0018] The beneficial effect of adopting the above further solution is that the movement of the moving block on the threaded rod is guided by inserting the column in the circular groove, so that the moving block can move stably on the threaded rod.

[0019] Furthermore, the bottom end of the rotating plate is fixedly connected to a second connecting seat, the bottom end of the second connecting seat is fixedly connected to an extension rod, a telescopic rod is inserted into the extension rod, pin holes are provided on the extension rod and the telescopic rod, and a pin is inserted into the pin hole.

[0020] The beneficial effect of adopting the above further scheme is that an extension rod is also fixed on the bottom end of the second connecting seat, and a telescopic rod is inserted inside the extension rod. By pulling out the pin inserted in the pin hole, the telescopic rod can be pulled out from the inside of the extension rod, so as to adjust the overall length of the fixed rod. The pin hole on the telescopic rod is aligned with the pin hole on the extension rod, and then the pin is inserted to re-fix the telescopic rod on the extension rod.

[0021] Furthermore, the rotating plate is designed to be semicircular, and a semicircular groove is provided on the rotating plate.

[0022] The beneficial effect of adopting the above further solution is that the rotating plate is designed to be semicircular, so as to facilitate splicing together, and the semicircular groove opened on the rotating plate is not located at the center of the rotating plate, so as to facilitate the position of the disc.

[0023] A method for fastening a live working drainage line comprises the following steps:

[0024] S1; first, place the wiring clamp on the mounting frame, lift up the upper part of the wiring clamp, and insert the drainage wire into one side of the wiring clamp to complete the placement of the drainage wire;

[0025] S2; Then rotate the fixing frame until the bottom part of the fixing frame is in a vertical state, and then turn the screw until the ejector rod rotatably connected to the bottom end of the screw abuts against the surface of the terminal clamp. The buckle fixed on the ejector rod will be stuck on the bolt at the top end of the terminal clamp, and the drainage wire on the terminal clamp will be fixed. After that, push the rotating frame upward so that it is perpendicular to the bottom part of the fixing frame. At this time, the top block rotatably connected to the rotating frame will abut against the fixing frame, thereby fixing the fixing frame. At this time, the terminal clamp will be fixed on the mounting frame;

[0026] S3; Then hold the fixing rod and gradually move the mounting frame closer to the cable. By rotating the disc, the moving block on the threaded rod is driven to move upward, and the rack and the connecting rod will move upward. Then, through the meshing of the rack and the gear, the angle of the mounting frame changes, so that the mounting frame can pass through the cable;

[0027] S4; Then rotate the disc again to return the angle of the mounting frame to the initial state. Then, align and snap the other side of the terminal clamp fixed on the mounting frame onto the cable to be installed;

[0028] S5; By sequentially rotating the bolts at the bottom end of the terminal clamp until the bolts are tightened, the terminal clamp together with the drainage wire can be fixed on the cable. Then, by pulling the rotating frame forcefully, the fixing of the top block on the fixing frame is released, and the fixing frame is driven to rotate. At this time, the ejector rod no longer abuts against the terminal clamp. Finally, retract the fixing rod.

[0029] Compared with the prior art, the live working drainage wire fastening device and the fastening method have the following beneficial effects:

[0030] 1), By setting the adjusting mechanism, rotating the disc can drive the threaded rod inside the cavity to rotate. The moving block threadedly connected to the threaded rod will move upward, thereby driving the connecting rod and the rack to move upward. When the rack moves upward through the meshing of the same gear, it drives the gear to rotate, so that the entire mounting frame rotates. At this time, the angle of the mounting frame can be adjusted to reduce the overall length of the mounting frame, so that the mounting frame will not touch other cables when passing through the power grid.

[0031] 2), By setting the protection mechanism, the function of protecting the disc is realized. Only by pressing the pressing block inward first, so that the insertion post fixed on the pressing block is inserted into the slot, and then when rotating the rotating plate, the disc can be driven to rotate together through the abutment of the insertion post and the slot, ensuring that the disc will not rotate due to accidentally touching the rotating plate.

The upper clamp body and the lower clamp body are connected by three sets of bolts. The bolts are located in the middle of the upper clamp body and the lower clamp body. Two accommodating grooves for accommodating cables and drainage cables are opened between the upper clamp body and the lower clamp body.

[0059] S1; first, place the wiring clip 71 on the mounting frame 1, lift up the upper part of the wiring clip 71, and insert the drainage wire into one side of the wiring clip 71 to complete the placement of the drainage wire;

[0060] S2; then rotate the fixing frame 66 until the bottom end of the fixing frame 66 is in a vertical state, and then screw the screw 65 until the top rod 63 rotatably connected to the bottom end of the screw 65 abuts against the surface of the wiring clamp 71, and the buckle 70 fixed on the top rod 63 will be stuck on the bolt at the top of the wiring clamp 71, and the drainage line on the wiring clamp 71 will be fixed, and then push the rotating frame 69 upward to make it perpendicular to the bottom end of the fixing frame 66. At this time, the top block 67 rotatably connected on the rotating frame 69 will support the fixing frame 66, thereby fixing the fixing frame 66, and at this time the wiring clamp 71 will be fixed on the mounting frame 1;

[0061] S3; then, the fixing rod 22 is held in hand to gradually bring the mounting frame 1 closer to the cable, and by rotating the disc 35, the moving block 30 on the threaded rod 32 is driven to move upward, the rack 26 and the connecting rod 27 will move upward, and then the angle of the mounting frame 1 is changed by the meshing of the rack 26 and the gear 23, so that the mounting frame 1 passes through the cable;

[0062] S4; then rotate the disc 35 again to restore the angle of the mounting frame 1 to its initial state, and then align and clamp the other side of the wiring clamp 71 fixed on the mounting frame 1 into the cable to be installed;

[0063] S5; by successively rotating the bolts on the bottom end of the wiring clamp 71 until the bolts are tightened, the wiring clamp 71 together with the drainage line can be fixed to the cable line, and then the fixing of the top block 67 to the fixing frame 66 is released by pulling the rotating frame 69 with force, and the fixing frame 66 is driven to rotate. At this time, the top rod 63 is no longer in contact with the wiring clamp 71, and finally the fixing rod 22 can be retracted.

[0064] It should be noted that, in this embodiment,

[0065] The specific method of use of the present invention is as follows: first, place the wiring clip 71 on the mounting frame 1, lift up the upper part of the wiring clip 71, and insert the drainage wire into one side of the wiring clip 71 to complete the placement of the drainage wire;

[0066] The fixing frame 66 is then rotated until the bottom end of the fixing frame 66 is in a vertical state, and the screw 65 is then turned until the top rod 63 rotatably connected to the bottom end of the screw 65 abuts against the surface of the wiring clamp 71, and the buckle 70 fixed on the top rod 63 is stuck on the bolt at the top of the wiring clamp 71, so that the upper clamp body and the lower clamp body clamp the drainage line close to one end of the drainage line, so that the drainage line on the wiring clamp 71 will be fixed. At the same time, since the drainage line goes deep into the receiving groove on one side, the other end of the upper clamp body and the lower clamp body will separate, so that the receiving groove on the other side is in an open state, and then the rotating frame 69 is pushed upward to make it perpendicular to the bottom end of the fixing frame 66. At this time, the top block 67 rotatably connected on the rotating frame 69 will support the fixing frame 66, thereby fixing the fixing frame 66, and the wiring clamp 71 will be fixed on the mounting frame 1.

[0067] Then, hold the fixed rod 22 and gradually move the mounting bracket 1 closer to the cable. Rotate the disc 35. The disc 35 is connected to the threaded rod 32 through the connecting member 34. At this time, the threaded rod 32 will rotate, and the moving block 30 threadedly connected to the threaded rod 32 will move upward. The front end of the moving block 30 is also connected to the connecting rod 27, thereby driving the connecting rod 27 to move upward inside the second chute 28. Since the rack 26 and the connecting rod 27 are connected and slide in the first chute 25 and the second chute 28 respectively, when the connecting rod 27 moves upward, it will drive the rack 26 to move in the first chute 25. The top part of the rack 26 meshes with the gear 23, so that the gear 23 rotates and drives the entire mounting bracket 1 to rotate, so as to adjust the angle of the mounting bracket 1, so that the mounting bracket 1 can pass through the power grid smoothly during installation.

[0068] After that, rotate the disc 35 again to return the angle of the mounting bracket 1 to the initial state. Then, align and snap the other side of the terminal clamp 71 fixed on the mounting bracket 1 onto the cable to be installed.

[0069] Then, align and snap the open receiving groove on the terminal clamp 71 onto the cable to be installed.

[0070] After that, sequentially rotate the bolts at the bottom end of the terminal clamp 71 through an external hand-operated lever until the bolts are tightened, then the terminal clamp 71 together with the bypass wire can be fixed on the cable. Then, pull the rotating frame 69 forcefully to release the fixing of the top block 67 on the fixing frame 66 and drive the fixing frame 66 to rotate. At this time, the ejector rod 63 no longer abuts against the terminal clamp 71. Finally, retract the fixed rod 22.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
