Description

Technical Field

[0001] The present invention belongs to the technical field of electric power fittings, and specifically is a nano aluminum alloy suspension wire clamp. Background Art

[0002] The nano suspension clamp is mainly composed of a clamp hull, a pressure plate, a U-bolt, a fastening device, and a nano waterproof coating sprayed on each clamp hull and pressure plate. Among them, the clamp hull is made of aluminum alloy and can accommodate and fix the overhead wire. It cooperates with the pressure plate and uses fastening devices such as U-bolts to confine the wire inside the hull, thereby ensuring the fixation of the wire.

[0003] For example, the invention with publication number CN202310622627.X discloses an energy-saving suspension wire clamp, which drives the rotating drum to rotate through the friction force generated by the pressure plate when the wire is pulled, so that the rope body is linked and wound around the outside of the rotating drum. At this time, the rope body is received and wound to drive the connected connecting plate to move vertically, giving pressure to the "U"-shaped hanging ring, so that it squeezes the push rod, and the push rod retracts due to the compression potential energy of the spring. After the pressure is removed, it rebounds due to the elastic potential energy of the spring, and is stuck between the groove and the sliding ring, thereby completing the self-locking effect. The above method avoids manual disassembly and assembly work, greatly simplifies the working steps, improves work efficiency, and this method greatly improves the fixing effect and stability.

[0004] The above scheme has problems in the process of fixing the conductor. First, when the suspension clamp is actually installed, an aluminum protective layer needs to be wrapped around the outside of the conductor to prevent the conductor from being worn in the suspension clamp, and the friction between the aluminum protective layer and the drum is small, which makes it impossible to rotate the drum when pulling the conductor. Secondly, since the conductor is heavy and the installation is done at high altitude, it is more laborious and dangerous to pull the conductor to rotate the drum. At the same time, since the rope body will be wrapped around the drum and contact the aluminum protective layer, since the voltage of the high-voltage conductor is very high during operation, and the part located in the wire clamp is also wrapped with an aluminum protective layer, the temperature of this part is higher than that of the exposed part (the temperature of the exposed part of the high-voltage overhead conductor should be 60℃-80℃), and when the part located in the wire clamp contacts the drum and the rope body, it will cause damage to the rope body, increasing the difficulty of maintenance. Therefore, in order to solve the above problems, a nano aluminum alloy suspension wire clamp is proposed. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a nano aluminum alloy suspension wire clamp, which solves the problem that the existing suspension wire clamp is laborious and cumbersome during installation.

[0006] To achieve the above object, the present invention provides the following technical solutions: a nano aluminum alloy suspension wire clamp, comprising a wire clamp assembly, a gland assembly and a U-shaped bolt body, all of which are sprayed with a nano waterproof coating, the wire clamp assembly comprising a wire clamp body and positioning grooves symmetrically arranged on the wire clamp assembly; The gland assembly comprises a gland body installed inside the wire clamp assembly and a groove symmetrically opened on the top of the gland body; The U-shaped bolt body comprises a frame body with two ends capable of being respectively inserted into two positioning grooves and a fixing assembly symmetrically arranged at the bottom of the frame body, and the curved portion at the top of the frame body can be buckled into the groove; The fixing assembly comprises two groups of limit rods symmetrically arranged at both ends of the frame body, the bottom ends of the limit rods extend to the bottom of the frame body and are movably sleeved with a sleeve on the outside, the bottom ends of the two limit rods are fixedly connected by movably connecting to the top block inside the sleeve, and the inside of the sleeve is also symmetrically and elastically hinged with a bending block, the bottom diameter of the sleeve is larger than the top diameter, the two bending blocks are in an "inverted eight shape" due to their own elastic force, and the projection of the two bending blocks in the vertical direction when they are stretched out overlaps with the wire clamp body; The top portion of the top block located between the two bending blocks is in a cone shape.

[0007] Preferably, the bending block has the bottom hinge as the axis; the upper middle portion of the bending block is solid, and a through hole is provided in the lower middle portion of the bending block; The upper part of the bending part of the bending block is always in an inclined state, and the center of gravity of the bending block is always located on the outer side of the axis.

[0008] Preferably, a ring is movably sleeved on the outside of the sleeve; the ring is initially located at the bottom of the sleeve, and when the ring moves upward, it can squeeze the bending block and shrink the bending block into the inside of the sleeve.

[0009] Preferably, the depth of the groove is greater than the length of the sleeve.

[0010] Preferably, a convex block is fixedly connected to one opposite side of the two groups of bending blocks, and the conical portion in the middle of the top block can squeeze the convex block when the top block moves upward.

[0011] Preferably, the limiting rod is fixedly connected to the frame body, and the top of the sleeve abuts against the top block.

[0012] Preferably, the limiting rod is movably connected to the frame, and a slider that can slide in the frame is fixedly connected to the top of the limiting rod; The diameter of the bottom of the limiting rod is smaller than the diameter of the upper part of the limiting rod.

[0013] Preferably, the wire clamp body is also provided with a notch connected to the positioning groove; The front and rear sides of the gland body are fixed with L-shaped blocks that can slide in the groove; one end of the slider extends to the outside of the frame, and the bottom of the slider and the bottom of the L-shaped block have an overlapping part in the vertical projection; a gap is left between the curved part of the top of the frame and the bottom of the groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The above scheme is fixed to the frame body through the limit rod. The operator first opens the gland assembly and the U-shaped bolt body, places the wire inside the wire clamp assembly, and then covers the gland body. Then, the two ends of the frame body are extended into the positioning groove and the sleeve is passed through the positioning groove to the bottom of the wire clamp body until the curved part at the top of the frame body is buckled in the groove. In the process of the sleeve passing through the positioning groove, the bending block will be squeezed and contracted by the inside of the positioning groove first. After the sleeve passes through the positioning groove, the bending block will be opened by its own elastic force. At this time, the frame body will be fixed on the wire clamp body by the fixing assembly, thereby avoiding the situation where the operator needs to pull the wire, and improving the efficiency of installing the suspension wire clamp; The above scheme uses the wind force in windy weather to make the wire shake, causing the wire to shake up and down inside the wire clamp body. When the wire shakes upward, the wire will push the frame upward through the pressure cover body. At this time, the limit rod will also move upward and drive the top block upward and squeeze the protrusion, thereby forcing the bending block to remain stably open in windy weather, thereby ensuring that the limit rod will not fall out of the positioning groove, further ensuring the stable limiting of the wire by the device.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 9 As shown, the present invention provides a nano aluminum alloy suspension wire clamp, comprising a wire clamp assembly 1, a gland assembly 2 and a U-shaped bolt body 3, all of which are sprayed with a nano waterproof coating on the outside, and the wire clamp assembly 1 comprises a wire clamp body 11 and a positioning groove 12 symmetrically opened on the wire clamp assembly 1; The gland assembly 2 includes a gland body 21 installed inside the wire clamp assembly 1 and a groove 22 symmetrically opened on the top of the gland body 21; The U-shaped bolt body 3 includes a frame body 31 with two ends that can be respectively inserted into the two positioning grooves 12 and a fixing assembly 32 symmetrically arranged at the bottom of the frame body 31, and the curved portion at the top of the frame body 31 can be buckled on the groove 22; The fixing assembly 32 comprises two groups of limiting rods 321 symmetrically arranged at two ends of the frame body 31, the bottom ends of the limiting rods 321 extend below the frame body 31 and are movably sleeved with a sleeve 322 on the outside, the bottom ends of the two limiting rods 321 are fixedly connected to the top block 323 inside the sleeve 322 by being movably connected, and the sleeve 322 is also symmetrically and elastically hinged with a bending block 324 inside the sleeve, the bottom diameter of the sleeve 322 is larger than its top diameter, the two bending blocks 324 are in an "inverted eight shape" due to their own elastic force, and the projections in the vertical direction when the two bending blocks 324 are stretched out overlap with the wire clamp body 11; the top portion of the top block 323 located between the two bending blocks 324 is conical; a convex block 3241 is fixedly connected to the opposite side of the two groups of bending blocks 324, and the conical portion in the middle of the top block 323 can squeeze the convex block 3241 when the top block 323 moves upward; the limiting rod 321 is fixedly connected to the frame body 31, and the top of the sleeve 322 abuts against the top block 323; The depth of the groove 22 is greater than the length of the sleeve 322; With the above scheme, the limiting rod 321 is fixed to the frame 31, and the operator first opens the gland assembly 2 and the U-shaped bolt body 3, places the wire inside the wire clamp assembly 1, and then covers the gland body 21, and then extends the two ends of the frame 31 into the positioning groove 12 and makes the sleeve 322 pass through the positioning groove 12 to the bottom of the wire clamp body 11 until the curved part at the top of the frame 31 is buckled in the groove 22. In the process of the sleeve 322 passing through the positioning groove 12, the bending block 324 will be squeezed and contracted by the inside of the positioning groove 12 first. After the sleeve 322 passes through the positioning groove 12, the bending block 324 will be opened by its own elastic force, and the frame 31 will be fixed to the wire clamp body 11 by the fixing assembly 32, thereby avoiding the situation where the operator needs to pull the wire, and improving the efficiency of installing the suspension wire clamp; Since the depth of the groove 22 is greater than the length of the sleeve 322, when the wire swings upward and pushes the gland body 21 upward, the top curved portion of the frame body 31 can always be ensured to be inside the groove 22, thereby enabling the device to work stably; At the same time, in windy weather, the wire will swing up and down inside the wire clamp body 11. When the wire swings upward, the wire will push the frame 31 upward through the pressure cover body 21. At this time, the limit rod 321 will also move upward and drive the top block 323 upward and squeeze the protrusion 3241, thereby forcing the bending block 324 to remain stably open in windy weather, thereby ensuring that the limit rod 321 will not separate from the positioning groove 12, further ensuring the stable positioning of the device on the wire.

[0019] like Figure 4 and Figure 5 As shown, the bending block 324 takes the bottom hinge as the axis; the upper middle portion of the bending block 324 is solid, and a through hole is provided in the lower middle portion of the bending block 324; The upper part of the bending part of the bending block 324 is always in an inclined state, and the center of gravity of the bending block 324 is always located on the outer side of the axis; By adopting the above scheme, since the top of the bending block 324 is solid and a through hole is opened at the bottom, and the center of gravity of the bending block 324 is always on the outer side of the axis of the bending block 324, when the spring piece used to support the bending block 324 is damaged, the bending block 324 can still remain in the open state, thereby ensuring that the frame 31 can always be fixed on the wire clamp body 11 through the bending block 324.

[0020] like Figure 5 and Figure 7 As shown, a sleeve 322 is also movably sleeved on the outside of the sleeve 322; the sleeve 3221 is initially located at the bottom of the sleeve 322, and when the sleeve 3221 moves upward, it can squeeze the bending block 324 and shrink the bending block 324 into the inside of the sleeve 322; By adopting the above scheme, during disassembly, the operator moves up the collar 3221 and shrinks the bending block 324 into the sleeve 322, then pushes the sleeve 322 upward to make it enter the positioning groove 12, and then lifts up the frame 31 to conveniently remove the U-shaped bolt body 3 as a whole.

[0021] like Figure 1-5 and Figure 7-9 As shown, the limiting rod 321 is movably connected to the frame 31 (this is the second connection method between the limiting rod 321 and the frame 31), and the top of the limiting rod 321 is also fixedly connected to a slider 3211 that can slide in the frame 31; the diameter of the bottom of the limiting rod 321 is smaller than the diameter of the upper part of the limiting rod 321; The wire clamp body 11 is also provided with a slot 111 communicating with the positioning slot 12; the front and rear sides of the gland body 21 are fixedly connected with L-shaped blocks 211 that can slide in the slot 111; One end of the slider 3211 extends to the outside of the frame 31, and the bottom of the slider 3211 overlaps with the bottom of the L-shaped block 211 in the vertical direction. There is a gap between the curved portion at the top of the frame 31 and the bottom of the groove 22; By adopting the above solution, the limiting rod 321 is movably sleeved inside the frame 31. When in use, the wire is placed inside the wire clamp assembly 1, and then the pressure cover body 21 is covered. At the same time, the L-shaped block 211 will also enter the notch 111. When the frame 31 is buckled, the bottom end of the slider 3211 will abut against the L-shaped block 211, and the bending block 324 will also open after the sleeve 322 passes through the positioning groove 12 to the bottom of the wire clamp body 11 to fix the frame 31; In windy weather, when the wire swings upward, it will squeeze the gland body 21 upward and drive the slider 3211 upward through the L-shaped block 211, so that the limit rod 321 first drives the top block 323 upward and squeezes the protrusion 3241, thereby forcing the bending block 324 to maintain a stable open state.

[0022] The working principle and use process of the present invention: The limiting rod 321 is fixed to the frame body 31. When in use, the operator first opens the gland assembly 2 and the U-shaped bolt body 3, places the wire inside the wire clamp assembly 1, and then covers the gland body 21. Then, the two ends of the frame body 31 are extended into the positioning groove 12 and the sleeve 322 is passed through the positioning groove 12 to the bottom of the wire clamp body 11 until the curved part at the top of the frame body 31 is buckled in the groove 22. When the sleeve 322 passes through the positioning groove 12, the bending block 324 will be squeezed and contracted by the inside of the positioning groove 12 first. After the sleeve 322 passes through the positioning groove 12, the bending block 324 will be opened by its own elastic force, and the frame body 31 will be fixed to the wire clamp body 11 by the fixing assembly 32; In windy weather, the wire will swing up and down inside the wire clamp body 11. When the wire swings upward, the wire will push the frame 31 upward through the pressure cover body 21. At this time, the limit rod 321 will also move upward and drive the top block 323 upward and squeeze the protrusion 3241, thereby forcing the bending block 324 to remain stably open in windy weather, thereby ensuring that the limit rod 321 will not disengage from the positioning groove 12, further ensuring that the device stably limits the wire.

[0023] The limiting rod 321 is movably sleeved inside the frame 31. When in use, the wire is placed inside the wire clamp assembly 1, and then the pressure cover body 21 is covered. At the same time, the L-shaped block 211 will also enter the notch 111. When the frame 31 is buckled, the bottom end of the slider 3211 will abut against the L-shaped block 211, and the bending block 324 will also open after the sleeve 322 passes through the positioning groove 12 to the bottom of the wire clamp body 11 to fix the frame 31; In windy weather, when the wire swings upward, it will squeeze the gland body 21 upward and drive the slider 3211 upward through the L-shaped block 211, so that the limit rod 321 first drives the top block 323 upward and squeezes the protrusion 3241, thereby forcing the bending block 324 to maintain a stable open state.

[0024] During disassembly, the operator moves the collar 3221 upwards and contracts the bending block 324 into the sleeve 322 , and then pushes the sleeve 322 upwards to enter the positioning groove 12 , and then lifts the frame 31 upwards to remove the U-shaped bolt body 3 as a whole.
