Description

Technical Field

[0001] The invention relates to the technical field of electric power safety, in particular to a bionic damping dovetail windproof equipment wire clamp. Background Art

[0003] The existing mature equipment wire clamps used on site use sheet metal aluminum as the carrier, and the tail uses a ductile iron bolt structure and a pressing plate to connect the wire to the equipment end. It can be used normally in areas with scarce wind resources and no vibration, but the effect is very poor in strong wind areas and high-frequency vibration environments.

[0004] The existing Chinese patent "CN 213692356 U A copper-aluminum transition equipment wire clamp" only adds an anti-slip structure design (anti-slip texture) for the guide wire head, but after tightening, it will directly damage the exposed root of the guide wire head, sharply aggravating the mechanical fatigue damage of the exposed root of the wire head, greatly reducing the overall connection reliability, and having low practicality.

[0005] The existing Chinese patent "CN117791185A A device wire clamp with a double fixing structure" has a poor applicability to guide wires of different wire diameters, and has a very complex structure, many parts, high manufacturing and processing difficulty, poor overall strength of the wire clamp, and poor practical reliability.

[0006] The existing Chinese patent "CN111509480B is a device for preventing wire breakage of equipment wire clamp". The additional anti-breaking design of the wire clamp can suppress the vibration and swing of the guide wire head to a certain extent. However, the additional device of the wire clamp is extremely poor in applicability to guide wires of different wire diameters, and has a delicate and complex structure, numerous parts, high difficulty in manufacturing, processing and installation, and poor overall strength. It greatly weakens the crimping and fixing strength of the guide wire head of the equipment wire clamp, and greatly increases the force of the lead wire vibration directly transmitted to the pressure plate bolt, making it easier to loosen. It increases the negative effect of the lead wire swinging force directly transmitted to the middle section of the equipment wire clamp (between the two sections of the wire clamp fixing lead part and the wire clamp equipment fixed connection part), and the middle section is perforated, which greatly reduces the strength of the middle section of the wire clamp, and has poor practicality and reliability.

[0063] Through the above technical scheme, when the nonlinear damping spring 4 is sleeved on the inner arc tightening sleeve 5, the conical surface 4031 and the limiting plane 4032 of the nonlinear damping spring 4 are first aligned with the inner arc tightening sleeve 5 and the thrust washer 3 plane respectively, so that the nonlinear damping spring 4 is axially fixed. At this time, the front end of the supporting rib claw 4033 contacts the outer ring of the inner arc tightening sleeve 5 to play a supporting role, the middle section of the supporting rib claw 4033 is suspended in the air, and the shock-transmitting support point 4034 at the tail end of the supporting rib claw 4033 is in close contact with the lead outer diameter of the wire 11, so that the vibration energy of the wire 11 can be transmitted to the nonlinear damping spring 4 to absorb and eliminate it.

[0064] In a possible embodiment, the end surface of the inner arc tightening sleeve 5 close to the thrust washer 3 is polished and provided with an axial pressure-bearing surface 501, and the connecting part of the two stepped cylindrical smooth parts of the inner arc tightening sleeve 5 is a spring limiting cone surface 502, and the spring limiting cone surface 502 is used to limit the movement of the inner arc tightening sleeve 5 in the direction away from the thrust washer 3, and the through hole 2 is a structure combining a columnar shape and a trumpet shape, and the trumpet-shaped structure is an inner arc polished trumpet-shaped surface 503, and the columnar structure is connected to the axial pressure-bearing surface 501.

[0066] In a possible implementation manner, the dovetail body 6 includes:

[0067] The dovetail body forging sheet metal part 601 has two bolt holes at its upper end, and the dovetail body forging sheet metal part 601 is fixed to the equipment terminal 8 by a bolt connection structure 1 9 and a bolt connection structure 2 10;

[0068] The dovetail body middle section 602 is cylindrically arranged, and the dovetail body middle section 602 and the dovetail body forged sheet metal part 601 are fixed by forging smooth transition, and the smooth transition fixation has high strength and dispersed stress. The dovetail body middle section 602 is provided with a dovetail body middle section threaded part 6021, and the dovetail body middle section 602 is sequentially installed with the special-shaped energy absorption spring 7, the anti-loosening nut 1 and the ordinary nut 2 in the circumferential direction from left to right, and the anti-loosening nut 1 and the ordinary nut 2 are respectively threadedly connected with the dovetail body middle section threaded part 6021; and

[0069] The dovetail 603 at the tail of the dovetail body is a dovetail finger structure, which is configured as at least three fingers, and is evenly distributed and fixedly arranged at one end of the dovetail body middle section 602 away from the dovetail body forging sheet metal part 601.

[0070] It should be noted that the middle section 602 of the dovetail body is mainly cylindrical, and the forged sheet metal part 601 of the dovetail body is the part connected to the equipment. The smooth forged part of the middle section 602 of the dovetail body and the forged sheet metal part 601 of the dovetail body transitions to sheet metal, which greatly improves the overall structural strength and avoids stress concentration and mechanical damage.

[0071] Through the above technical scheme, the forged sheet metal part 601 of the dovetail body can be connected to the equipment terminal 8 through the bolt connection structure 1 9 and the bolt connection structure 2 10, and the three evenly distributed dovetail body tail dovetails 603 at the tail end of the tail dovetail body 6 are deformed by the radial force of the inner arc tightening sleeve 5.

[0072] It should be added that the forged sheet metal part 601 of the dovetail body can increase or decrease the number of connecting bolt holes according to actual application conditions or be processed into other shapes through forging and welding technology, so as to adapt to the wiring part of the connecting equipment; the dovetail 603 at the tail of the dovetail body can be prevented from electrochemical corrosion by aluminum plating, spray coating, etc.

[0073] In a possible implementation manner, the conductive wire 11 includes a guide wire head threaded portion fixed to the dovetail body 6 and a conductive wire lead.

[0074] In a possible embodiment, the dovetail body tail dovetail 603 includes a dovetail body dovetail middle section smooth arc surface section 6032 that is tightly fitted with and conductive to the threaded portion of the guide wire head, and one end of the dovetail body dovetail middle section smooth arc surface section 6032 is fixedly provided with a dovetail body dovetail front end bionic serrated inverted grain section 6031 that is engaged with the wire lead, and the dovetail body dovetail front end bionic serrated inverted grain section 6031 can effectively prevent the wire lead from slipping, and the other end of the dovetail body dovetail middle section smooth arc surface section 6032 is fixedly provided with a dovetail body dovetail bionic trumpet-shaped tail section 6033 that smoothly limits the swing of the wire 11.

[0075] By adopting the above technical solution, after the threaded portion of the guide wire head is fixedly installed with the bionic serrated inverted groove section 6031 at the front end of the dovetail body, the inner arc tightening sleeve 5 and the nonlinear damping spring 4 are installed on the dovetail body 6 in sequence, and then the ordinary nut 2 and the anti-loosening nut 1 are fixed on the threaded portion 6021 in the middle section of the dovetail body in sequence. After the anti-loosening nut 1 and the ordinary nut 2 are tightened, the force is transmitted to the thrust washer 3, and the thrust washer 3 transmits the force to the inner arc tightening sleeve 5. The inner arc tightening sleeve 5 is forced to move in the direction away from the thrust washer 3, and the direction of the force is changed by the inner arc polished bell-shaped curved surface 503. The force changes from axial to radial, squeezing the dovetail bionic trumpet-shaped tail section 6033 of the dovetail body, so that the three evenly distributed dovetail finger structures of the dovetail bionic trumpet-shaped tail section 6033 of the dovetail body gradually move radially, pressing the wire end of the wire 11, and the bionic serrated inverted grain section 6031 at the front end of the dovetail body is embedded in the wire 11 to prevent it from falling off. The smooth arc surface section 6032 in the middle section of the dovetail body is closely combined with the wire 11 for conduction. The dovetail bionic trumpet-shaped tail section 6033 of the dovetail body can suppress and limit the swing amplitude of the wire 11, prevent stress concentration, and cause damage to the root of the wire end of the wire 11.

[0076] It needs to be explained that the dovetail 603 at the tail of the dovetail body is designed to imitate the structural characteristics of grass growth in windy areas and is a three-claw curved dovetail, which comprehensively curbs the swing amplitude of the conductor 11 and eliminates the stress concentration phenomenon at the root of the lead head; the dovetail 603 at the tail of the dovetail body clamps the lead head part, imitating the principle of three-finger coordination of human hands to grasp small objects, and designs a three-claw structure relying on the inner arc tightening sleeve 5 to achieve synchronous and balanced force compression and compression of the conductor 11 by the three grippers, thereby reducing the deformation and extension space of the conductor 11, and the bionic serrated inverted grain section 6031 at the front end of the dovetail of the dovetail body is a serrated inverted grain structure similar to the mouth of a carnivore, which inhibits the slippage of the conductor 11, and the middle section 602 of the dovetail body is a smooth section, which increases the conductive contact area, and the fastening structure still retains a certain adaptability of the equipment wire clamp to guide wires of different wire diameters.

[0077] In a possible implementation, the bionic sawtooth inverted grain section 6031 at the front end of the dovetail body and the smooth arc surface section 6032 in the middle section of the dovetail body are both cylindrical structures, so as to increase the contact area with the lead head of the wire.

[0078] In a possible implementation, a long bolt hole is provided at the front end of the special-shaped energy absorbing spring 7, the middle section of the special-shaped energy absorbing spring 7 is an elastic energy absorbing action area, and the tail end of the special-shaped energy absorbing spring 7 is a cylindrical open-type retaining spring.

[0079] In a possible implementation, the special-shaped energy-absorbing spring 7 is fixed to the long bolt hole through the bolt connection structure 10, and the cylindrical open-type retaining spring is nested and compacted on the smooth arc surface section 6032 of the middle section of the dovetail body, transmitting and absorbing vibration energy, and suppressing the stress damage caused by the vibration and swing transmitted from the wire lead between the equipment wire clamp and the equipment fixing area and the equipment wire clamp body. At the same time, with the help of the fixation of the special-shaped energy-absorbing spring 7, a double-nut mechanical anti-loosening structure between the equipment and the wire clamp is realized, and the fixing strength of the wire clamp is simultaneously improved.
