Description

Technical Field

[0001] The invention relates to the technical field of electric power maintenance, and in particular to a drainage line fixing device. Background Art

[0002] Drain wire is a kind of wire used to connect or disconnect circuits in power systems. It is mainly used in engineering projects to connect and disconnect drain wires without power outages. During the use of drain wires, it is generally required to use drain wire fixtures. Drain wire fixtures are widely needed in live working. Live working refers to a special working method of repairing and testing power transmission equipment under live conditions. Electrical equipment needs to be frequently inspected and maintained during long-term operation. Live working is an effective measure to avoid power outages and ensure normal power supply.

[0003] At present, when my country's power industry is carrying out projects of replacing pole-mounted equipment with load or disconnecting and connecting jumpers, the way to fix the drain wires and jumpers is mostly with the help of insulating shielding tools. After insulating and shielding the grounding bodies such as poles, towers or crossarms, they are placed on insulated components or the disconnected live jumpers are fixed by forcibly bending them and then tying them back to the main line. Not only a large number of shielding tools are required in the operation, but the safety factor of the shielding tools is low when used, and the corresponding labor intensity is increased. At the same time, forced bending of the equipment may damage the equipment, resulting in low efficiency during operation and increased danger for personnel during operation. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a drain wire fixing device to solve the problem that during the installation of the original drain wire, shielding tools are mostly used for shielding and insulation, the safety factor of the drain wire shielding and insulation is low, and a large amount of shielding tools are used, which increases the corresponding labor intensity.

[0005] In order to achieve the above object, the basic scheme of the present invention is as follows: a drainage wire fixing device comprises:

[0006] Cross arm clamp;

[0007] A plurality of rotating connectors, one end of which is mounted on the cross arm clamp;

[0008] A telescopic rod, one end of which is rotatably mounted or locked and fixed on an end of a rotating connector away from the cross arm clamp;

[0009] The wire clamp fixing head is installed on one end of the telescopic rod away from the rotating connecting head, and the wire clamp fixing head is detachably connected to the drainage line.

[0010] The technical principle of the present invention is: when the drainage line fixing device is in use, the operating personnel sit on the insulating bucket and transfer to the pole tower. The operating personnel cooperate to use shielding tools to shield parts of the pole tower, crossarms, pole-mounted equipment and wires to provide insulation protection before the operation.

[0011] During this process, the workers on the ground first control the rotation of the connecting head and the telescopic rod according to the support direction and support length of the drainage line. The telescopic rod can be telescopically adjusted so that the end of the drainage line is opposite to the connection point of the cable under the guidance of the wire clamp fixing head and the end of the telescopic rod; at the same time, by rotating the connecting head, the angle between the end of the telescopic rod and the crossarm clamp is controlled, thereby changing the arrangement angle of the telescopic rod close to the end of the wire clamp fixing head, and then adjusting the support angle at the end of the drainage line. Under the support and guidance of the crossarm, telescopic rod and wire clamp fixing head, the drainage line is not easy to contact with grounding bodies such as crossarms and poles, and is also not easy to contact with other positions of the cable, which can significantly reduce the use of shielding equipment and reduce labor intensity; by adjusting the rapid adjustment of the telescopic rod at different angles, the safe distance between the human body and the live body during live work can be effectively guaranteed, thereby improving the safety of the operation.

[0012] Further, the cross arm clamp comprises:

[0013] The clamp body has a longitudinal cross-sectional profile in a "T" shape, and the lower end of the clamp body is bent upward and can abut against one side edge of the cross arm;

[0014] The adjusting pressing part is installed on the clamp body, and the adjusting pressing part adjusts the clamp body to be pressed tightly or loosely installed on the cross arm;

[0015] A limiting guide ring is provided for the drainage line to pass through, and the limiting guide ring is installed at the upper side of the clamp body.

[0016] Through the above-mentioned arrangement, the adjusting clamping part can cooperate with the clamp body, so that the clamp body can be stably installed on the cross arm, and can be adjusted by adjusting the clamping part, so that the adjusting clamping part is loosened from the cross arm, making it convenient to disassemble and assemble the clamp body on the cross arm; the guide ring can perform limiting guidance with the middle part of the drainage line, so that the longer drainage line is less likely to be scattered on the drainage line fixing device, and the distribution of the drainage line is more controllable, allowing the operator to have more operating space.

[0017] Further, the adjusting pressing part comprises:

[0018] A hydraulic telescopic part, which is installed at the middle of the vertical section of the clamp body;

[0019] A micro hydraulic pump controls the vertical extension and retraction of the hydraulic expansion and retraction part, and the micro hydraulic pump is fixedly installed on the top of the clamp body.

[0020] Through the above arrangement, when the clamp body is installed on the cross arm, the micro hydraulic pump is controlled to start, and the micro hydraulic pump controls the hydraulic telescopic rod to shorten, so that the lower end of the clamp body moves upward and close to the upper end of the clamp body, thereby clamping the clamp body as a whole on the cross arm, making the clamping operation of the clamp body more convenient and reliable; it is also more convenient to control the looseness of the clamp body from the cross arm.

[0021] Further, the adjusting pressing part comprises:

[0022] An adjusting screw rod is vertically adjustable and installed at one side of the upper end of the clamp body, and a limiting guide ring is installed on the upper end of the adjusting screw rod;

[0023] A tightening piece can be pressed against the cross arm, and the tightening piece is fixedly installed on the lower end of the adjusting screw.

[0024] Through the above arrangement, by rotating the adjusting screw, the adjusting screw pushes the clamping plate to the surface of the cross arm, so that the clamp body can be clamped and fixed to the cross arm. The clamp body can be clamped and loosened easily, and the rotating operation of the adjusting screw is simple.

[0025] Further, the rotating connector includes:

[0026] A fixed support column, one end of which is fixedly mounted on the fixture body;

[0027] A first connecting plate, the first connecting plate is fixedly mounted on an end of the fixed support column away from the clamp body;

[0028] A plurality of first meshing teeth, the first meshing teeth are fixedly arranged on the end surface of the first connecting disk, and the plurality of first meshing teeth are evenly arranged around the circumference of the first connecting disk;

[0029] A second connecting plate, the second connecting plate is fixedly connected to an end of the telescopic rod away from the wire clamp fixing head;

[0030] A plurality of second meshing teeth that can mesh with the first meshing teeth, the second meshing teeth being fixedly arranged on the end surface of the second connecting disk, and the plurality of second meshing teeth being evenly arranged around the circumference of the first connecting disk;

[0031] The locking head, the first connecting plate and the second connecting plate are coaxially provided with a locking hole for the locking head to pass through.

[0032] When the locking head is in a locked position, the first and second connecting plates are locked and the locking teeth are in a locked position, so that the locking head can be stably installed in the locking hole, and the gap between the first and second connecting plates is reduced. The first and second connecting plates are tightly meshed again, so that the first and second connecting plates are tightly connected, so that the rotation direction of the telescopic rod is adjusted in place and the support direction is stably controlled, so that the support direction and support length of the drainage line can be effectively controlled, so that the drainage line can be reliably fixed away from grounding bodies such as cross arms and poles to avoid grounding short circuit.

[0033] Furthermore, a thread connected to a locking head is provided in the locking hole of the first connecting disk or the second connecting disk, and the locking head can abut against the end surface of the first connecting disk or the second connecting disk.

[0034] Through the above arrangement, the locking head can stably coaxially connect and install the first connecting disk or the second connecting disk together. The threaded connection makes the locking connection between the locking head and the first connecting disk or the second connecting disk more convenient and reliable, and makes it easy to adjust the angle of the telescopic rod.

[0035] Furthermore, the axes of the first connecting plate and the second connecting plate may be parallel to the horizontal installation direction of the cross arm.

[0036] Through the above arrangement, when adjusting the angle of the telescopic rod, the plane where the telescopic rod angle is adjusted is parallel to the vertical plane where the cable is located, so that the telescopic rod can drive the end of the drainage line close to the side wall of the cable or away from the side wall of the cable, making the end of the drainage line easier to cooperate and connect with the cable.

[0037] Furthermore, a locking ring is provided at the middle of the telescopic rod for locking or loosening the telescopic rod for length adjustment.

[0038] By setting the locking ring, the length adjustment of the telescopic rod is convenient and reliable.

[0039] Furthermore, a wire clamp hole for the drainage wire to pass through is provided on the wire clamp fixing head, and the aperture of the wire clamp hole is adjustable.

[0040] Through the above arrangement, the diameter of the wire clamp hole is adjustable, and drainage wires of various specifications can be reliably clamped. The wire clamp fixing head can also stably clamp the drainage wire, making the installation between the drainage wire and the cable more stable.

[0041] Furthermore, there are a plurality of rotating connectors, each of which is located at one end of a limiting guide ring on the upper side of the clamp body, and the rotating connector can be located on the upper side or the lower side of the end of the clamp body.

[0042] Through the above-mentioned arrangement, rotating connectors and telescopic rods are provided on the upper and lower sides of the clamp body, which can be conveniently used in the unilateral fixing scenarios of the upper and lower drainage lines, thereby increasing the scope of application; at the same time, when the drainage line fixing device is in use, it can also be adjusted according to the installation direction of multiple cross arms on the pole tower, the number of cross arms and the installation position of the drainage line, and the installation position of the clamp body and the number of installation of the drainage line fixing devices, so as to fully and stably support and limit the drainage line.

[0057] At the same time Figure 1 As shown, the axes of the first connecting plate 301 and the second connecting plate 303 may be parallel to the horizontal installation direction of the cross arm 1 .

[0058] like Figure 1 and Figure 3 As shown, a locking ring 403 for locking or loosening the telescopic rod 40 for adjusting the length is provided at the middle part of the telescopic rod 40, the left end of the telescopic rod 40 is a fixed shaft 401, and the left end of the telescopic rod 40 is a movable shaft 402. The locking ring 403 is fixedly installed at the right end of the fixed shaft 401, and a locking bead is provided in the locking ring 403. The locking ring 403 can rotate forward to control the locking bead to move toward the center of the locking ring 403 and then lock it to the outer wall of the movable shaft 402. The locking ring 403 can rotate backward to control the locking bead to move away from the center of the locking ring 403 and then release the movable shaft 402, so that the movable shaft 402 can move horizontally relative to the fixed shaft 401, thereby controlling the overall length of the telescopic rod 40; the left end of the fixed shaft 401 is integrally formed with the side wall of the second connecting disk 303, and the axial direction of the telescopic rod 40 is perpendicular to the axial direction of the second connecting disk 303.

[0059] like Figure 1 and 3As shown, the wire clamp fixing head 50 includes a fixed limit block 501, an articulated limit block 502, a hook threaded rod 503 and a butterfly nut 504 threadedly connected to the hook threaded rod 503. The right side of the fixed limit block 501 is hinged to the right side of the articulated limit block 502 through a pin shaft. A wire clamp hole for the drainage line to pass through is formed horizontally between the fixed limit block 501 and the articulated limit block 502. The axis of the wire clamp hole is parallel to the axis of the pin shaft. Flanges are provided on the left sides of the fixed limit block 501 and the articulated limit block 502. The upper end of the hook threaded rod 503 is hinged to the flange of the articulated limit block 502. A hanging groove 505 for the hook threaded rod 503 to penetrate is provided at the flange of the fixed limit block 501. The butterfly nut 504 can be abutted against the lower side of the flange of the fixed limit block 501: the fixed limit block 501 is welded to the right end of the movable shaft 402.

[0060] In addition, the locking ring 403 and the wire clamp fixing head 50 are both made of high-strength polymer insulating material.

[0061] Before installing the drainage line in the drainage line fixing device of this embodiment, the workers take the insulating bucket to transfer to the pole tower, and the workers cooperate to use shielding tools to shield parts of the pole tower, cross arm 1, pole-mounted equipment and wires to provide insulation protection before the operation.

[0062] The operator on the ground first controls the supporting length and direction of the telescopic rod 40 on the clamp body 20 according to the supporting direction and supporting length of the drainage line. When adjusting, the operator holds the screwing head 306 on the locking head 305 and rotates the locking head 305 forward to loosen the first connecting disk 301 and the second connecting disk 303, and the meshing part of the first meshing tooth 302 and the second meshing tooth 304 is separated. At this time, the telescopic rod 40 can be rotated, and the telescopic rod 40 drives the second connecting disk 303 and the second meshing tooth 304 to rotate relative to the first connecting disk 301 and the first meshing tooth 302. When the telescopic rod 40 is rotated to the required supporting direction, the locking head 305 is rotated in the opposite direction so that the end of the locking head 305 is screwed to the locking hole of the first connecting disk 301, and the first connecting disk 301 and the second connecting disk 302 are locked. The gap between the plates 303 is reduced, and the first meshing teeth 302 and the second meshing teeth 304 are tightly meshed again, thereby realizing a tight connection between the first connecting plate 301 and the second connecting plate 303, so that the rotation direction of the telescopic rod 40 is adjusted in place and the supporting direction is stably controlled; when controlling the supporting length of the telescopic rod 40, the locking ring 403 between the fixed shaft 401 and the movable shaft 402 is rotated in the reverse direction, and the locking bead moves away from the center of the locking ring 403 and then releases the movable shaft 402, so that the movable shaft 402 can be extended and retracted relative to the axial direction of the fixed shaft 401. When the overall length of the telescopic rod 40 reaches the required length, the locking ring 403 is rotated forward, and the locking bead moves toward the center of the locking ring 403 and then locks to the outer wall of the movable shaft 402, thereby realizing the adjustment and locking of the length of the telescopic rod 40.

[0063] Then loosen the butterfly nut 504 on the hook threaded rod 503, so that the hook threaded rod 503 can pass through the hanging groove 505, allowing the hinged limit block 502 to rotate relative to the hinge of the fixed limit block 501, install the middle part of the drainage line to the wire clamp hole, and then rotate and close the wire clamp holes of the hinged limit block 502 and the fixed limit block 501, and the hook threaded rod 503 is embedded in the hanging groove 505 again, and the butterfly nut 504 is screwed up so that the butterfly nut 504 is pressed against the fixed limit block 501, thereby clamping the drainage line and achieving preliminary fixation of the drainage line.

[0064] The workers in the insulating bucket cooperate with the workers on the ground again to lift the drainage line fixing device as a whole to the upper end of the pole tower. The workers in the insulating bucket transfer the clamp body 20 to the crossarm 1. At this time, the lower end bend of the clamp body 20 is buckled to the lower edge of the crossarm 1. At this time, hold the limiting guide ring 21 and screw the adjusting screw 22 downward. The lower end of the adjusting screw 22 drives the clamping plate 23 to be tightened to the upper side of the crossarm 1, so that the clamp body 20 can be adjusted and buckled to the crossarm 1. The lower end bend of the clamp body 20 can be stably buckled to the crossarm 1; then the end of the drainage line away from the wire clamp fixing head 50 can be passed through the limiting guide ring 21 to limit the middle part of the drainage line.

[0065] Through the above process, the limiting guide ring 21 and the wire clamp fixing head 50 can fully support and guide the drainage line. At the same time, the support length and support angle adjustment of the telescopic rod 40 can effectively control the support direction and support length of the drainage line, so that the drainage line can be reliably fixed away from grounding bodies such as crossarms 1 and poles to avoid grounding short circuits; the limiting guide ring 21 and the wire clamp fixing head 50 made of high-strength polymer insulating materials meet the mechanical strength requirements and achieve full insulation; at the same time, the wire clamp fixing head 50 is structurally coordinated with the fixed limiting block 501, the hinged limiting block 502 and the hook threaded rod 503, and the diameter of the wire clamp hole is adjustable, which is suitable for a cross-sectional area of ​​50-240mm 2 It can reliably clamp drainage wires of various specifications.

[0066] At the same time, through the cooperation of the first connecting plate 301, the first meshing tooth 302, the second connecting plate 303, the second meshing tooth 304 and the locking head 305, the rotating connecting head located on one side of the clamp body 20 can control the telescopic rod 40 to be adjustable in the horizontal direction of 180°, which is convenient for supporting and fixing drainage lines of various lengths. At the same time, by adjusting the quick adjustment of the telescopic rod 40 at different angles, the safe distance between the human body and the live body during live working is effectively guaranteed; at the same time, the upper and lower sides of the clamp body 20 are both provided with rotating connecting heads and telescopic rods 40, which can be conveniently used in the unilateral fixing scenes of the upper and lower drainage lines, thereby increasing the scope of application; at the same time, according to the installation directions of multiple cross arms 1 on the pole tower, the number of cross arms 1 and the installation position of the drainage line, the installation position of the clamp body 20 and the number of drainage line fixing devices can be adjusted, so that a single drainage line can be supported to span across two drainage line fixing devices, and the drainage line can be fully and stably supported, thereby improving the safety and stability of operation during live working.

[0067] Example 2

[0068] The difference between Example 2 and Example 1 is basically as shown in the attached Figure 4 and 5 As shown, the adjusting and tightening part includes a hydraulic telescopic part and a micro hydraulic pump 60 for controlling the vertical telescopic movement of the hydraulic telescopic part.

A guide embedded groove 203 is provided in the lower end of the fixed section 201. The hydraulic telescopic rod 601 is vertically and coaxially installed on the guide embedded groove 203 of the fixed section 201. In the embedded groove 203, the upper end of the clamping section 202 is also located in the guide embedded groove 203, the upper end of the hydraulic telescopic rod 601 is fixedly connected to the top surface of the guide embedded groove 203 of the fixed section 201, and the lower end of the hydraulic telescopic rod 601 is fixedly connected to the top of the clamping section 202; at the same time, the micro hydraulic pump 60 is fixedly installed on the top of the clamp body 20, and a hydraulic connecting pipe is provided between the micro hydraulic pump 60 and the hydraulic telescopic rod 601, and the hydraulic connecting pipe passes through the fixed section 201 and is connected to the upper end of the hydraulic telescopic rod 601.

[0069] At the same time, a mounting ring 701 is provided on the outer coaxial sleeve of the locking ring 403, and two elastic insulating support strips 702 are installed on the circumference of the mounting ring 701. The surface of the end of the insulating support strip 702 close to the locking ring 403 is an arc surface that fits on the outer wall of the locking ring 403. A groove 703 for the drainage line to pass through is horizontally penetrated on the end of the insulating support strip 702 away from the mounting ring 701. An embedding groove 704 that is connected to the groove 703 and for the drainage line to be embedded is provided at the end edge of the insulating support strip 702, and the width of the embedding groove 704 is less than the maximum width of the groove 703.

[0070] In addition, it also includes a control unit, which includes a PLC processor, a first switch button 602, a second switch button 603, an infrared signal generator, an infrared signal receiver, a remote control shell 604, a controller for controlling the micro hydraulic pump 60 to turn on or off, and a battery. The first switch button 602 is installed on the upper side of the clamp body 20, and the clamp body 20 is electrically connected to the first switch button 602. The PLC processor and the infrared signal generator are installed in the remote control shell 604, and the second switch button 603 is installed on the remote control shell 604. The infrared signal generator, the second switch button 603 and the infrared signal receiver are all electrically connected to the PLC processor by signals. The infrared signal receiver is located on the micro hydraulic pump 60 and is electrically connected to the micro hydraulic pump 60 by signals. The battery is electrically connected to the micro hydraulic pump 60, the first switch button 602 and the infrared signal receiver.

[0071] When the drainage line fixing device in this embodiment is in use, when the clamp body 20 is installed on the cross arm 1, if the working clearance between the cross arms 1 is sufficient for the operator, the operator presses the first switch button 602, and the first switch button 602 controls the micro hydraulic pump 60 to start, and the micro hydraulic pump 60 controls the hydraulic telescopic rod 601 to shorten, so that the upper end of the clamping section 202 moves into the embedded groove, so that the upper side of the clamp body 20 is pressed against the cross arm 1, and the clamping section 202 of the clamp body 20 is also clamped and pressed against the lower side edge of the cross arm 1 synchronously, so that the installation of the clamp body 20 on the cross arm 1 is simple and convenient, and the clamping is convenient and efficient; when the cross arm 1 When the working space between the workers is cramped, the worker in the insulating bucket holds the telescopic rod 40 and pre-fastens the clamp body 20 to the cross arm 1, and then notifies the worker on the ground to press the second switch button 603 on the remote control shell 604. The second switch button 603 transmits the signal to the PLC processor, and the PLC processor controls the micro hydraulic pump 60 to transmit the signal to the infrared signal generator. The infrared signal receiver receives the control signal and transmits it to the controller. The controller controls the micro hydraulic pump 60 to start, which can also realize the rapid clamping of the clamp body 20 to the cross arm 1 and improve the safety of the clamp body 20 during installation.

[0072] When adjusting the length of the telescopic rod 40, the operator can hold the insulating support bar 702 and the locking ring 403. The setting of the insulating support bar 702 makes it easier for the operator to exert force on the locking ring 403, which can quickly drive the locking ring 403 to rotate, and then quickly apply force to adjust the length of the telescopic rod 40; at the same time, when positioning and supporting the drainage line, the middle part of the drainage line can be deformed and squeezed into the card slot 703 through the embedded groove 704, and the card slot 703 of the insulating support bar 702 can limit the support of the drainage line, so that the middle part of the drainage line is further stably supported, further preventing the drainage line from contacting the crossarm 1, poles and other grounding bodies, and avoiding grounding short circuit; the insulating support bar 702 can be driven by the mounting ring 701 to rotate relative to the locking ring 403 in the circumferential direction, and the support angle of the insulating support bar 702 can be adjusted, which is convenient for precise support of the drainage line.

[0073] Example 3

[0074] The difference between Example 3 and Example 1 is basically as shown in the attached Figure 6 , Figure 7 and Figure 8 As shown, it also includes a drainage line storage unit, which includes a winding accommodating box 80, a support rod 801, a reel 802, a torsion spring 803 and a sleeve 804. The support rod 801 is arranged radially along the upper end of the movable shaft 402, the left end of the support rod 801 is welded to the movable shaft 402, and the right end of the support rod 801 is coaxially welded to the winding accommodating box 80; Figure 8 At any time, the reel 802, the torsion spring 803 and the sleeve 804 are coaxially sleeved from the inside to the outside and are coaxially installed in the winding container 80, the two ends of the reel 802 are fixedly connected to the winding container 80, one end of the torsion spring 803 is welded to the side wall of the reel 802, and the other end of the torsion spring 803 is welded to the inner wall of the sleeve 804; Figure 6 As shown, a wire entry hole 81 for the drainage wire to pass through is provided on one side of the side wall of the winding accommodating box 80 close to the insulating support strip 702, and a wire exit hole 82 for the drainage wire to pass through is provided on the left end face of the winding accommodating box 80. The middle part of the drainage wire can be wound onto the sleeve 804.

[0075] In addition, the drainage wire storage units are all made of high-strength polymer insulation materials.

[0076] When the drainage wire fixing device in this embodiment is in use, a longer drainage wire can be wound in the winding accommodating box 80. When the drainage wire is connected to the cable, the drainage wire at the wire clamp fixing head 50 is loosened, and the end of the drainage wire is pulled out and connected to the cable. At this time, the middle part of the drainage wire drives the sleeve 804 to rotate, and the sleeve 804 drives the torsion spring 803 to rotate, so that the drainage wire is pulled out. When the end of the drainage wire is connected to the cable, the wire clamp fixing head 50 clamps the drainage wire to fix the drainage wire. After the above process, the middle part of the drainage wire is not easy. In this process, the drainage wire can be more stably guided and tensioned between the cables by the drainage wire fixing device, and it is also less likely to contact with grounding bodies such as crossarms 1 and poles, and more operating space can be left for operators.

[0077] When the operation is completed, the connection between the drain wire and the cable is disassembled, the drain wire at the wire clamp fixing head 50 is loosened, the potential energy of the torsion spring 803 is released, and the drain wire is reeled in more automatically, so that when the drain wire fixing device is raised and lowered along the pole, the free end of the drain wire on the drain wire fixing device is in a relatively fixed state, and is less likely to interfere with other cables or equipment. It is also easier to use and install the drain wire fixing device, and can reduce the amount of shielding equipment used and reduce the operating intensity.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
