Description

Technical Field

[0001] The invention belongs to the technical field of cable repair and relates to a transmission cable repair device. Background Art

[0002] With the development of the power system, the coverage of the transmission network continues to expand, and the grid structure is becoming increasingly complex. As a key link in power transmission, the health of the transmission cable directly affects the reliable operation of the entire power system. Therefore, regular inspection and maintenance of cables have become an indispensable part of ensuring power supply. Aging, damage or failure of any cable may cause power outages and even cause larger-scale power grid accidents. Therefore, once the cable is found to be damaged, it needs to be repaired in time.

[0003] At present, for damaged power transmission cables, the usual method is to complete the repair work manually or using special maintenance machines. When using maintenance machines to repair broken strands, most existing maintenance machines use a binding strap locking method to temporarily restore the structural integrity of the cable. However, only using a simple binding strap locking method to repair the cable will cause the cable conductors to be only vertically connected and not actually entangled together. As a result, the tensile strength of a single conductor will decrease, which can easily pose a safety hazard in subsequent use. Summary of the invention

DETAILED DESCRIPTION

[0027] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] A transmission cable maintenance device, such as Figure 1-Figure 4 As shown, it includes a bracket 1, a handle 2, a side frame 3, an electric wheel 4, an arc-shaped clamping plate 55, a clamping mechanism, a repair mechanism and a driving mechanism. The left and right sides of the bracket 1 are connected to two inclined side frames 3, and a handle 2 is connected between the tops of the two side frames 3. The electric wheels 4 are installed on the side frames 3. When the bracket 1 is placed on the cable 100, the two electric wheels 4 on both sides clamp the front and rear sides of the cable 100 respectively, and then the electric wheels 4 are controlled to rotate to drive the bracket 1 to move along the cable 100. The bracket 1 A clamping mechanism for clamping the cable 100 is provided on the clamping mechanism, and two arc-shaped clamping plates 55 are provided on the clamping mechanism. The two arc-shaped clamping plates 55 can be spliced ​​to form an annular sleeve, and the annular sleeve can be sleeved on the outside of the cable 100. The clamping mechanism can drive the arc-shaped clamping plates 55 to be spliced ​​together and sleeved on the cable 100. The arc-shaped clamping plates 55 are provided with a repairing mechanism for repairing the cable 100, and a driving mechanism for driving the arc-shaped clamping plates 55 to rotate is provided between the clamping mechanism and the arc-shaped clamping plates 55.

[0029] like Figure 2 As shown, the clamping mechanism includes a mounting frame 51, a cylinder 52, a connecting head 53 and an arc guide rail 54. The mounting frames 51 are installed on the left and right sides of the bracket 1, and the cylinder 52 is installed in the middle of the mounting frame 51. The connecting head 53 is connected to the telescopic rod of the cylinder 52, and the arc guide rail 54 is slidably connected to the connecting head 53. When the two arc guide rails 54 are connected, they can form a circular track. Two arc clamping plates 55 are respectively connected to the inner sides of the two arc guide rails 54.

[0030] like Figure 3 As shown, the repair mechanism includes an electric push rod 61 and a guide block 62. Three electric push rods 61 are evenly spaced and installed on each arc-shaped clamping plate 55. The telescopic rod of the electric push rod 61 is connected to the guide block 62. The guide block 62 is provided with a guide groove. When moving, the guide block 62 can support the wire of the cable 100 through the guide groove, and then can help gather the wires when moving again.

[0031] like Figure 3 and Figure 4As shown, the driving mechanism includes an arc-shaped rack 71, a driving motor 72 and a driving gear 73. The driving motor 72 is installed on the right side of the connecting head 53, and the driving gear 73 is connected to the output shaft of the driving motor 72. The arc-shaped racks 71 are connected to the right sides of the two arc-shaped clamping plates 55, and the arc-shaped racks 71 are meshed with the driving gear 73. When the two arc-shaped clamping plates 55 are put together, the two arc-shaped racks 71 are connected to form a ring, and then the driving motor 72 drives the driving gear 73 to rotate, and the arc-shaped clamping plates 55 can be driven to rotate through the arc-shaped racks 71.

[0032] When it is necessary to repair a cable 100 with some broken wires, the present device can be used. The present embodiment is specifically aimed at repairing a cable 100 in which six wires are wound around each other. When in use, the bracket 1 is first set up at a position on the cable 100 where the wires are wound around each other, so that the two electric wheels 4 on both sides respectively press against the front and rear sides of the cable 100, and then the telescopic rods of the two cylinders 52 are controlled to approach each other, and the arc clamping plates 55 on both sides are driven to be sleeved on the cable 100 through the connector 53 and the arc guide rail 54. After the sleeve is completed, the electric push rod 61 is controlled to extend the telescopic rod to drive the guide block 62 to press against the six outer wires, and then the electric wheel 4 is controlled to rotate to drive the present device along the cable 1 00 moves, and at the same time, controls the driving motor 72 to drive the driving gear 73 to rotate. When the driving gear 73 rotates, it can drive the arc rack 71 to rotate, thereby driving the arc clamping plate 55, the electric push rod 61 and the guide block 62 to rotate, so that the guide block 62 can rotate along the wound wire during the movement. If a wire swings down due to breakage, the guide block 62 can squeeze the wire during the movement of the guide block 62, so that the wire is rewound together to assist in the repair of the wire. In this way, the present device can be used to assist in the repair of the cable 100 wire, and the repair is carried out by rewinding the wire together, which can ensure the performance of the repaired wire.

[0033] like Figure 5 and Figure 6 As shown, it also includes a pushing mechanism, which includes a connecting plate 81, a connecting frame 82, an inclined frame 83, a pushing roller 84 and an elastic member 85. The two mounting frames 51 are slidably connected to the connecting plate 81 on the side close to each other. The connecting plate 81 is connected to the telescopic rod of the cylinder 52. The left and right sides of the connecting plate 81 are slidably connected to the connecting frame 82. An elastic member 85 is connected between the connecting frame 82 and the connecting plate 81. The elastic member 85 is a buffer spring. The connecting frame 82 is connected to the inclined frame 83 on the side close to the arc clamping plate 55. The pushing roller 84 is rotatably connected to the inclined frame 83.

[0034] When the telescopic rod of the cylinder 52 is extended, the connecting plate 81 can be driven to move together. When the connecting plate 81 moves, it can drive the connecting frame 82 to move through the elastic member 85. When the connecting frame 82 moves, it can drive the inclined frame 83 and the pushing roller 84 to move together, so that the pushing roller 84 supports the bottom of the cable 100, assists the cable 100 to move upward, allows the cable 100 to maintain contact with the electric wheel 4, and prevents the cable 100 from drooping downward and separating from the electric wheel 4, and the elastic member 85 can play a buffering role.

[0035] like Figure 7-Figure 9 As shown, it also includes a lubrication mechanism, which includes a cylinder body 91, an arc-shaped liquid storage frame 92, an air injection pipe 93, a piston rod 94, a cone block 95, an arc-shaped piston plate 96, an oil injection pipe 97 and an elastic member 98. The cylinder body 91 is installed in the middle of the two arc-shaped clamping plates 55, and the two arc-shaped clamping plates 55 are connected to the arc-shaped liquid storage frame 92. The arc-shaped liquid storage frame 92 is filled with a lubricating liquid, and the lubricating liquid used is non-corrosive. The cylinder body 91 is slidably connected to a piston rod 94, and one end of the piston rod 94 extends out of the cylinder body 91. An elastic member 98 is connected between the piston rod 94 and the cylinder body 91, and the elastic member 98 is a reset spring. One end of the piston rod 94 extending out of the cylinder body 91 is connected to a cone block 95, and the connecting plate 81 is located at the moving trajectory of the cone block 95. A plurality of air inlet holes are evenly spaced apart on the side of the cylinder body 91 facing the cone block 95. An air injection pipe 93 is connected between the cylinder body 91 and the arc-shaped liquid storage frame 92. Both the air injection pipe 93 and the piston part of the piston rod 94 are provided with a one-way valve. An arc-shaped piston plate 96 is slidably connected in the arc-shaped liquid storage frame 92. The air injection pipe 93 can squeeze the arc-shaped piston plate 96 to move by injecting air into the arc-shaped liquid storage frame 92. An oil injection pipe 97 is connected between the right side of the arc-shaped liquid storage frame 92 and the middle of the three guide blocks 62 close to it.

[0036] When the arc-shaped clamping plate 55 rotates, it can drive the cylinder body 91 to rotate. When the cylinder body 91 rotates, it can drive the cone block 95 to rotate together. When the cone block 95 rotates, it contacts the connecting plate 81 and is squeezed by the connecting plate 81 to move inward, thereby driving the piston rod 94 to move. The elastic member 98 is compressed. When the piston rod 94 moves, it can inject the gas in the cylinder body 91 into the arc-shaped liquid storage frame 92 through the gas injection pipe 93, thereby squeezing the arc-shaped piston plate 96 to move, so that the arc-shaped piston plate 96 squeezes the lubricating liquid in the arc-shaped liquid storage frame 92, and injects the lubricating liquid into the cable 100 through the oil injection pipe 97, so that the conductors of the cable 100 can be better wound together when they are entangled with each other.

[0037] like Fig.10As shown, it also includes an arc-shaped connecting block 101 and a cleaning brush 102. The right sides of the two arc-shaped clamping plates 55 are connected to the arc-shaped connecting block 101, and the inner arc surface of the arc-shaped connecting block 101 is evenly spaced and connected to a plurality of cleaning brushes 102.

[0038] When the arc-shaped clamping plate 55 rotates, it can drive the arc-shaped connecting block 101 and the cleaning brush 102 to rotate together. Through this rotational motion, the cleaning brush 102 can clean the impurities on the surface of the cable 100, effectively preventing the impurities from adhering to the surface of the cable 100, thereby ensuring that the surface of the cable 100 is clean and tidy. This not only improves the transmission efficiency of the cable 100, but also extends the service life of the cable 100 and reduces failures caused by surface dirt.

[0039] like Fig.11 As shown, a friction sleeve 11 is also included, and the friction sleeve 11 is connected to the outer side of the electric wheel 4.

[0040] The design of the friction sleeve 11 can increase the friction force when the electric wheel 4 contacts the cable 100, effectively preventing the electric wheel 4 from idling when driving the cable 100. By enhancing the friction coefficient between the two, it ensures that the electric wheel 4 can smoothly and effectively drive the cable 100 to move, thereby improving the reliability and work efficiency of the system, while also reducing the problem of equipment damage or unstable transmission of the cable 100 caused by slipping.

[0041] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
