Description

Technical Field

[0001] The present invention relates to the technical field of power cable construction, in particular to cleaning equipment for power cable construction. Background Art

[0002] Power cables are used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power station outbound lines, internal power supplies for industrial and mining enterprises, and underwater transmission lines across rivers and seas. The proportion of cables in power lines is gradually increasing. Power cables are used to transmit and distribute high-power electrical energy within the backbone lines of power systems. They include power cables with voltage levels ranging from 1 to 500 kV and above, and with various insulation levels.

[0003] Cables have good resistance to high voltage and magnetic interference and are widely used in temporary electrical circuits. In some harsh working environments during cable construction, cables will produce stains on the surface insulation layer during use, such as dust and dirt. When the stains on the cable surface insulation layer are serious, it may even affect the normal use of the cable. Some existing traditional cable cleaning methods mainly rely on manual cleaning by operators. When cleaning the cable, the surface needs to be cleaned, which has low cleaning efficiency and consumes a lot of manpower. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a cleaning device for power supply cable construction, comprising a frame body, which is used for stably supporting the power cable, and a support frame is fixedly installed on the top of the frame body; a friction cleaning component, which is used for cleaning dust on the surface of the power cable, and connecting rods are fixedly installed on both sides of the outer surface of the friction cleaning component, and a guide ring is fixedly installed on the bottom of the connecting rod; a guide component, which is used for stably conveying the power cable; the friction cleaning component is fixedly installed at the middle of the top of the support frame, and the friction cleaning component is mounted inside the frame body through the support frame, and the guide component is arranged below the support frame, The guide assembly is rotatably installed between the opposite surfaces of the frame; during the construction of power cables, the workers need to clean the stains attached to the surface of the cables. Since the cables are often coiled into a coil for maintenance, during the cable construction, the workers pull out the front end of the cable and pass it through the guide ring, friction cleaning assembly and guide assembly on one side in turn, and then pass it out from the other side to complete the cleaning of the stains on the cable surface; the guide rings on both sides guide the cable, and when the cable passes through the friction cleaning assembly, the friction cleaning assembly and the cable are squeezed and deformed, so that the friction cleaning assembly fits against the cable surface, and the stains attached to the cable surface are cleaned. At this time, the curvature caused by the winding of the cable is squeezed and stretched.

[0005] The friction cleaning assembly includes a beam frame, with insertion plates fixedly mounted on both ends of the outer surface of the beam frame. The insertion plates extend through the beam frame and extend below the beam frame. Two insertion plates are provided, symmetrically arranged with the beam frame as the center. A guide ring is fixedly mounted on the top of each insertion plate, and an extrusion cleaning piece is fixedly mounted inside the guide ring. The beam frame and insertion plates support and position the guide rings at both ends. When the cable passes through the guide ring, it is squeezed by the extrusion cleaning piece installed inside. The guide ring and the extrusion cleaning piece deform according to the thickness of the cable model and cover the surface of the cable, so as to facilitate the cleaning of cables of different models and improve cleaning efficiency.

[0006] Preferably, the beam is fixedly installed in the middle of the top of the support frame, the through-plate passes through the beam and extends to the inside of the frame, the guide ring is installed inside the frame through the through-plate, and two groups of guide rings are provided, and the two groups of guide rings and the guide rings and guide components are arranged on the same central axis.

[0007] Preferably, the guide ring comprises a collar, an inner wall of which is fixedly mounted an elastic bend, a side of the elastic bend close to the inner wall of the collar having an arc groove, a surface of the elastic bend away from the arc groove having a positioning pad fixedly mounted thereon, and a connecting rod fixedly mounted between opposite surfaces of the positioning pad. Since the power cable is relatively thick and heavy, it will vibrate when it is pulled and guided. When the cable vibrates, the elastic bend is affected by the shaking and squeezes against the collar, causing the elastic bend to be squeezed and displaced toward the side of the arc groove, thereby providing stable support for the cable and preventing the vibration of the cable from colliding with the guide ring.

[0008] Preferably, the collar is fixedly mounted on the bottom of the insertion plate, the elastic bent frame is distributed in a circular shape on the inner wall of the collar, and the connecting rod is fixedly mounted on both sides of the outer surface of the extrusion cleaning piece.

[0009] Preferably, the extrusion cleaning member includes a mounting plate, two of which are provided, with a curved sheet fixedly mounted between opposing surfaces of the two mounting plates, and side plates fixedly mounted on both sides of the outer surfaces of the curved sheet, both sides of the outer surfaces of the side plates being fixedly connected to the outer edges of the mounting plates. When the cable passes through the guide ring, it is stuck between the friction brushes when passing between the curved sheets. Since the bottom of the curved sheet is provided with a hollow structure, the cable and the curved sheet are deformed and recessed toward one side of the side plate, and the friction brush is deformed and displaced in the direction of the recessed curved sheet.

[0010] Preferably, a friction brush sheet is fixedly installed on the surface of the curved plate, and two groups of friction brush sheets are provided. The two groups of friction brush sheets are symmetrically arranged with the curved plate as the center, and the friction brush sheets are arranged between the opposite surfaces of the side plates, and the side plates are fixedly installed on the outer surface of the connecting rod.

[0011] Preferably, the friction brush piece includes a connecting plate, a positioning plate fixedly mounted on the top of the connecting plate, a raised block fixedly mounted on the top of the positioning plate, a spring piece fixedly connected to the surface of the connecting plate away from the raised block, a friction block fixedly mounted on the outer surface of the spring piece, and a grooved brush provided on the surface of the friction block. The deformation and depression of the curved plate drive the displacement of the friction block, causing the spring piece to be squeezed by the curved plate and displaced toward the side of the connecting plate, so that the grooved brush fits the surface of the cable, rubbing against it when the cable is pulled, cleaning the stains attached to the surface while the multiple groups of grooved brushes protect the curved cable surface.

[0012] Preferably, the guide assembly includes a housing, expansion cavities fixedly mounted on both sides of the outer surface of the housing, support rods fixedly mounted on the sides of the outer surface of the housing, and sliding guide rollers fixedly mounted inside the cavity of the housing. The cable passes through the sliding guide rollers, and when the cable is pulled, the sliding guide rollers are driven to rotate, thereby facilitating cable guidance and transportation.

[0013] Preferably, the shell is fixedly mounted between opposite surfaces of the frame through a support rod, the sliding guide roller is arranged between two groups of guide rings, and the sliding guide roller and the guide ring are arranged on the same central axis.

[0014] Preferably, the sliding guide roller includes folding plates, and the folding plates are provided in four groups. The four groups of folding plates are arranged opposite to the inner cavity of the shell. A support plate is fixedly installed between the inner walls of the folding plates. Cross rods are fixedly installed on both sides of the outer surfaces of the folding plates. Round wheels are rotatably installed between the opposite surfaces of the cross rods. When a worker pulls the cable through the shell, the round wheels are provided around the inner wall of the shell. When the wire is twisted, the wire generates friction with the surface of the round wheels, causing the round wheels to rotate on the surface of the cross rods as the wire moves, thereby improving the smoothness of the wire pulling. When the wire moves between the multiple groups of round wheels, it is squeezed by the round wheels, causing the curved parts of the wire to be squeezed and straightened by the round wheels.

[0015] The present invention provides a cleaning device for power cable construction. It has the following beneficial effects: 1. The cleaning equipment for power cable construction is used when workers need to clean the stains attached to the surface of the power cable during construction. Since the cable is often coiled into a coil for maintenance, the worker pulls out the front end of the cable and passes it through the guide ring, friction cleaning component and guide component on one side in turn, and then passes it out from the other side to complete the cleaning of the stains on the cable surface; the guide rings on both sides guide the cable, and when the cable passes through the friction cleaning component, the friction cleaning component and the cable are squeezed and deformed, so that the friction cleaning component fits the cable surface, and the stains attached to the cable surface are cleaned. At this time, the curvature caused by the cable winding is squeezed and stretched.

[0016] 2. The cleaning equipment for power cable construction supports and positions the guide rings at both ends through beams and insertion plates. When the cable passes through the guide ring, it is squeezed by the extrusion cleaning parts set inside it. The guide ring and the extrusion cleaning parts are deformed according to the thickness of the cable model and covered on the surface of the cable, so as to facilitate the cleaning of cables of different models and improve the cleaning efficiency.

[0017] 3. The cleaning equipment for the power cable construction, when the cable passes through the guide ring, the cable is stuck between the friction brushes when passing through the curved pieces. Since the bottom of the curved piece is set as a hollow structure, the cable and the curved piece are deformed and concave toward the side plate. At this time, the friction brush is deformed and displaced in the direction of the concave curved piece. Since the power cable is relatively thick and heavy, it will shake when it is pulled and guided. When the cable shakes, the elastic bend frame is affected by the shaking and squeezed against the ring, causing the elastic bend frame to be squeezed and displaced toward the side of the arc groove, thereby providing stable support for the cable and preventing the vibration of the cable from colliding with the guide ring.

[0018] 4. The cleaning equipment for the power supply cable construction drives the displacement of the friction block by the deformation of the curved plate, so that the spring piece is squeezed by the curved plate and displaced toward the side of the connecting plate, so that the grooved brush can fit on the surface of the cable and rub against it when the cable is pulled, cleaning the stains attached to its surface while multiple groups of grooved brushes protect the curved cable surface.

[0019] 5. The cleaning equipment for the power cable construction is that the staff pulls the cable to make it pass through the shell, and circular wheels are provided around the inner wall of the shell. When the wire is twisted, the wire pull generates friction with the surface of the circular wheel, so that the circular wheel rotates on the surface of the cross rod as the wire moves, so as to improve the smoothness of the wire pulling, and when the wire moves between multiple sets of circular wheels, it will be squeezed by the circular wheels, so that the curved part of the wire is squeezed and straightened by the circular wheels.

[0031] The first embodiment, as Figures 1 to 2 As shown, the present invention provides a technical solution: a cleaning device for power cable construction, comprising a frame 5, which is used for stably supporting the power cable, and a support frame 1 is fixedly installed on the top of the frame 5; a friction cleaning component 2, which is used for cleaning dust on the surface of the power cable, and a connecting rod 3 is fixedly installed on both sides of the outer surface of the friction cleaning component 2, and a guide ring 6 is fixedly installed on the bottom of the connecting rod 3; a guide component 4, which is used for stable transmission of the power cable; the friction cleaning component 2 is fixedly installed in the middle of the top of the support frame 1, and the friction cleaning component 2 is mounted on the inside of the frame 5 through the support frame 1, and the guide component 4 is arranged below the support frame 1, and the guide component 4 rotates It is installed between the opposite surfaces of the frame 5; during the construction of the power cable, the staff needs to clean the stains attached to the surface of the cable. Since the cable is often coiled into a coil for maintenance, during the cable construction, the staff pulls out the front end of the cable and passes it through the guide ring 6, the friction cleaning component 2 and the guide component 4 on one side in turn, and then passes it out from the other side to complete the cleaning of the stains on the cable surface; the guide rings 6 on both sides guide the cable, and when the cable passes through the friction cleaning component 2, the friction cleaning component 2 and the cable are squeezed and deformed, so that the friction cleaning component 2 fits against the cable surface, and the stains attached to the cable surface are cleaned. At this time, the curvature caused by the winding of the cable is squeezed and stretched.

[0032] The second embodiment, based on the first embodiment, see Figures 3 to 7 As shown, the friction cleaning assembly 2 includes a beam 21, with insertion plates 22 fixedly mounted on both ends of the outer surface of the beam 21. The insertion plates 22 extend through the beam 21 to the bottom thereof. Two insertion plates 22 are provided, and the two insertion plates 22 are symmetrically arranged with the beam 21 as the center. A guide ring 23 is fixedly mounted on the top of each insertion plate 22, and an extrusion cleaning member 24 is fixedly mounted inside the guide ring 23. The beam 21 and the insertion plates 22 support and position the guide rings 23 at both ends. When the cable passes through the guide ring 23, it is squeezed by the extrusion cleaning member 24 arranged inside the guide ring 23. The guide ring 23 and the extrusion cleaning member 24 are deformed according to the thickness of the cable model and are coated on the surface of the cable, so as to facilitate the cleaning of cables of different models and improve cleaning efficiency.

[0033] Preferably, the beam 21 is fixedly installed in the middle of the top of the support frame 1, the through-plate 22 passes through the beam 21 and extends to the interior of the frame 5, and the guide ring 23 is installed inside the frame 5 through the through-plate 22. There are two groups of guide rings 23, and the two groups of guide rings 23 are arranged on the same central axis as the guide ring 6 and the guide assembly 4.

[0034] Preferably, the guide ring 23 includes a collar 231, an elastic bend 232 fixedly mounted on the inner wall of the collar 231, an arc groove 234 being formed on the side of the elastic bend 232 close to the inner wall of the collar 231, a positioning pad 235 fixedly mounted on the surface of the elastic bend 232 away from the arc groove 234, and a connecting rod 233 fixedly mounted between the opposite surfaces of the positioning pad 235. Since the power cable is relatively thick and heavy, it will shake when it is pulled and guided. When the cable shakes, the elastic bend 232 is affected by the shaking and squeezes the collar 231, causing the elastic bend 232 to be squeezed and displaced toward the arc groove 234, thereby providing stable support for the cable and preventing the vibration of the cable from colliding with the guide ring 23.

[0035] Preferably, the collar 231 is fixedly mounted on the bottom of the insertion plate 22 , the elastic bent frame 232 is distributed in a circular shape on the inner wall of the collar 231 , and the connecting rod 233 is fixedly mounted on both sides of the outer surface of the extrusion cleaning piece 24 .

[0036] Preferably, the extrusion cleaning member 24 includes two mounting plates 243. A curved sheet 241 is fixedly mounted between opposing surfaces of the two mounting plates 243. Side plates 244 are fixedly mounted on both sides of the outer surfaces of the curved sheets 241. Both sides of the outer surfaces of the side plates 244 are fixedly connected to the outer edges of the mounting plates 243. When the cable passes through the guide ring 23, it passes between the curved sheets 241 and is stuck between the friction brushes 242. Since the bottom of the curved sheets 241 is a hollow structure, the cable and the curved sheets 241 are deformed and recessed toward the side plates 244. At this time, the friction brushes 242 deform and displace in the direction of the recessed curved sheets 241.

[0037] Preferably, a friction brush sheet 242 is fixedly installed on the surface of the curved plate 241, and two groups of friction brush sheets 242 are provided. The two groups of friction brush sheets 242 are symmetrically arranged with the curved plate 241 as the center, and the friction brush sheets 242 are arranged between the opposite surfaces of the side plates 244, and the side plates 244 are fixedly installed on the outer surface of the connecting rod 233.

[0038] Preferably, the friction brush piece 242 includes a connecting plate 2423, a positioning plate 2422 fixedly mounted on the top of the connecting plate 2423, a protrusion 2421 fixedly mounted on the top of the positioning plate 2422, a spring piece 2425 fixedly mounted on the surface of the connecting plate 2423 away from the protrusion 2421, a friction piece 2426 fixedly mounted on the outer surface of the spring piece 2425, and a grooved brush 2424 provided on the surface of the friction piece 2426. The deformation and depression of the curved piece 241 drive the friction piece 2426 to move, causing the spring piece 2425 to be squeezed by the curved piece 241 and displaced toward the side of the connecting plate 2423, so that the grooved brush 2424 can fit the surface of the cable, rubbing against it when the cable is pulled, cleaning the dirt attached to the surface, and protecting the curved cable surface with multiple groups of grooved brushes 2424.

[0039] The third embodiment, based on the first and second embodiments, see Figures 8 and 9 As shown, the guide assembly 4 includes a housing 44, with expansion cavities 43 fixedly mounted on both sides of the outer surface of the housing 44, support rods 41 fixedly mounted on the outer side of the housing 44, and sliding guide rollers 42 fixedly mounted inside the cavity of the housing 44. The cable passes through the sliding guide rollers 42, and when the cable is pulled, the sliding guide rollers 42 are driven to rotate, thereby facilitating cable guidance and transportation.

[0040] Preferably, the housing 44 is fixedly mounted between opposite surfaces of the frame 5 via the support rod 41 , the sliding guide roller 42 is disposed between the two sets of guide rings 23 , and the sliding guide roller 42 and the guide rings 23 are disposed on the same central axis.

[0041] Preferably, the sliding guide roller 42 includes folding plates 423, which are provided in four groups. The four groups of folding plates 423 are arranged opposite to the inner cavity of the shell 44. A support plate 424 is fixedly installed between the inner walls of the folding plates 423. Cross rods 421 are fixedly installed on both sides of the outer surface of the folding plates 423. Round wheels 422 are rotatably installed between the opposite surfaces of the cross rods 421. The staff pulls the cable to pass through the shell 44. Round wheels 422 are provided around the inner wall of the shell 44. When the wire is twisted, the wire generates friction with the surface of the round wheels 422, so that the round wheels 422 rotate on the surface of the cross rods 421 as the wire moves, thereby improving the smoothness of the wire when being pulled. When the wire moves between the multiple groups of round wheels 422, it is squeezed by the round wheels 422, so that the curved part of the wire is squeezed and straightened by the round wheels 422.

[0042] During use, during the construction of the power cable, the workers need to clean the stains attached to the surface of the cable. Since the cable is often coiled into a coil for maintenance, the workers pull out the front end of the cable and pass it through the guide ring 6, the friction cleaning component 2 and the guide component 4 on one side in turn, and then pass it out from the other side to complete the cleaning of the stains on the cable surface; the guide rings 6 on both sides guide the cable, and when the cable passes through the friction cleaning component 2, the friction cleaning component 2 and the cable are squeezed and deformed, so that the friction cleaning component 2 fits against the cable surface, and the stains attached to the cable surface are cleaned. At this time, the curvature caused by the winding of the cable is squeezed and stretched.

[0043] The beam frame 21 and the insertion plate 22 support and position the guide rings 23 at both ends. When the cable passes through the guide ring 23, it is squeezed by the extrusion cleaning piece 24 arranged inside it. The guide ring 23 and the extrusion cleaning piece 24 are deformed according to the thickness of the cable model and are covered on the surface of the cable to facilitate the cleaning of cables of different models and improve cleaning efficiency.

[0044] Since the power cable is relatively thick and heavy, it will shake when it is pulled and guided. When the cable shakes, the elastic bend frame 232 is affected by the shaking and squeezes the ring 231, causing the elastic bend frame 232 to be squeezed and displaced toward the side of the arc groove 234, thereby providing stable support for the cable and avoiding collision between the cable pulling vibration and the guide ring 23.

[0045] When the cable passes through the guide ring 23, the cable is stuck between the friction brush pieces 242 when passing between the curved pieces 241. Since the bottom of the curved piece 241 is set as a hollow structure, the cable and the curved piece 241 are deformed and recessed toward the side plate 244. At this time, the friction brush piece 242 is deformed and displaced in the direction of the recessed curved piece 241.

[0046] The curved piece 241 is deformed and depressed, driving the friction block 2426 to move, so that the spring piece 2425 is squeezed by the curved piece 241 and depressed toward the side of the connecting plate 2423, so that the grooved brush 2424 can fit on the surface of the cable and rub against it when the cable is pulled, cleaning the stains attached to its surface. At the same time, multiple groups of grooved brushes 2424 protect the curved cable surface.

[0047] The cable passes through the sliding guide roller 42 and drives the sliding guide roller 42 to rotate when the cable is pulled, so as to facilitate the guided transportation of the cable.

[0048] The staff pulls the cable to pass through the shell 44. Round wheels 422 are provided around the inner wall of the shell 44. When the wire is twisted, the wire is pulled and friction is generated between the surface of the round wheel 422, so that the round wheel 422 rotates on the surface of the cross rod 421 as the wire moves, so as to improve the smoothness of the wire pulling. When the wire moves between multiple sets of round wheels 422, it will be squeezed by the round wheel 422, so that the curved part of the wire is squeezed and straightened by the round wheel 422.

[0049] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
