Description

[0001] This application is a divisional application of the application filed on September 25, 2024, with application number 202411339943.7 and invention name “A cross-river cable traction device”. Technical Field

[0002] The present invention relates to the technical field of cable traction, in particular to a river-spanning cable traction device. Background Art

[0003] The traction of cross-river cables usually requires the use of large drones or helicopters to pull them across the air, or the use of ferries to cross the river, and then towing one end of the cross-river cable to the other end of the river. Since some cross-river cables are relatively thick and heavy, these two traction methods have higher requirements for the machines used for crossing the air and crossing the river, and the operating costs are also higher.

[0004] In the existing technology, some methods first transport one end of a thin towing rope to the other side of the river by a simple transportation method, and then fix a thicker cross-river cable to the thinner towing rope, and use the thin towing rope to carry the thicker cross-river cable across the river, similar to the "threading a needle" method to transport one end of the cross-river cable to the other side of the river. However, in this method, after the cross-river cable is transported to the shore, it is necessary to manually remove the cross-river cable from the thinner towing rope and then fix the cross-river cable to the shore. The manual disassembly and installation process is relatively slow, and the cross-river cable may slip into the river, resulting in failure of towing. Summary of the Invention

[0015] The present invention provides a cross-river cable traction device through improvement, which has the following improvements and advantages compared with the prior art:

[0016] First: When the cable body needs to be towed across the river, one end of the cable body and the traction rope are first fixed together through a connecting frame and bolts, and the other end of the traction rope is wound around the winding rod. Then, the plug-in platform and the fixing seat are transferred to the other side by a boat or other convenient means of transportation, and the fixing seat is fixed on the shore. Then, the drive motor is started, and the traction rope on the winding rod is reeled in. When the traction rope and the cable body move to the other side, one end of the cable body will move to the inner cavity of the plug-in platform, and the plug-in rod will be inserted into the plug-in slot. Then, the plug-in rod squeezes the bottom end of the upper support rod. , so that the upper support rod moves downward to prevent the upper end of the upper support rod from squeezing the cable body. When the upper support rod slides downward, one end of the plug-in rod will be inserted into the plug-in hole. Then the squeezed trapezoidal stopper will pop out downward first, so that the plug-in rod is clamped in the plug-in hole. The setting of the locking mechanism can prevent the cable body from being pulled underwater due to the impact of water flow when being fixed, which will affect the installation of the cable. When the cable body is pulled to the shore, it can be automatically pre-fixed without removing the traction rope, which reduces the workload of the staff and improves the efficiency of the fixed connection.

[0017] Secondly, due to the effect of water flow, the position of the plug rod may rotate or swing. When one end of the cable body is close to the plugging platform, the arc-shaped push rod is inserted into the rotating slide groove. If the angle of the arc-shaped push rod changes, the arc-shaped push rod will be squeezed by the inclined sliding surface on the special-shaped extrusion ring block, causing the arc-shaped push rod, the connecting frame and the plug rod to rotate to the initial position. The positioning mechanism is set to ensure that the plug rod can be inserted into the plug slot, and the twisting of the cable body can be prevented from causing damage to the cable body.

[0018] Third, when the upper support rod moves downward, the upper support rod drives the fixed link and the lifting frame downward, causing the lifting frame to squeeze the sliding clamping rod inward, so that the two sliding clamping rods approach each other, and then the clamping head clamps the cable body located in the docking station. By setting up the auxiliary fixing mechanism, while the locking mechanism fixes the cable body and the docking station, the connection between the cable body and the docking station can be made more secure, and the tension on the locking mechanism can also be shared;

[0019] To sum up, the setting of the locking mechanism can prevent the cable body from being pulled underwater when fixed due to the impact of the water flow, which will affect the installation of the cable. When the cable body is pulled to the shore, it can be automatically pre-fixed without removing the traction rope, which reduces the workload of the staff and improves the efficiency of the fixed connection. The setting of the positioning mechanism can ensure that the plug-in rod can be inserted into the plug-in slot, and can also prevent the cable body from twisting and causing damage to the cable body. Through the setting of the auxiliary fixing mechanism, while the locking mechanism fixes the cable body and the plug-in platform, the cable body and the plug-in platform can be connected more firmly, and the tension on the locking mechanism can also be shared.

When the upper support rod 93 slides downward, one end of the plug-in rod 91 will be inserted into the insertion hole 94, and then the squeezed trapezoidal stopper 95 will pop out downward first, causing the plug-in rod 91 to be clamped in the insertion hole 94 to prevent the cable body 5 from being pulled underwater when fixed due to the impact of the water flow.

[0035] In another embodiment provided by the present invention, the auxiliary fixing mechanism 10 includes a fixed connecting rod 103 fixed to the bottom end of the upper support rod 93, the other end of the fixed connecting rod 103 is located in the plug-in platform 1, and one end of the fixed connecting rod 103 located in the plug-in platform 1 is fixed to a lifting frame 104, and the lifting frame 104 is set to slide up and down in the plug-in platform 1. The lower side of the lifting frame 104 is located in the plug-in platform 1 and is provided with a sliding clamping rod 101 for horizontal sliding. There are two sliding clamping rods 101. They are arranged relative to each other, and the upper sides of the opposite ends of the two sliding clamping rods 101 are fixed with clamping heads 102, and the clamping heads 102 are movably inserted into the inner wall of the inner cavity of the docking station 1.

There are several second springs 105, and the several second springs 105 are arranged at equal intervals. The opposite ends of the two clamping heads 102 are arranged in an arc shape.

[0036] Specifically, when the upper support rod 93 moves downward, the upper support rod 93 drives the fixed link 103 and the lifting frame 104 to move downward, so that the lifting frame 104 squeezes the sliding clamping rod 101 inward, so that the two sliding clamping rods 101 approach each other, and then the clamping head 102 clamps the cable body 5 located in the docking station 1.

[0037] In another embodiment provided by the present invention, the positioning mechanism 8 includes a rotating slide groove 81 provided on a side wall of the plug-in platform 1 close to the cable body 5. There are two rotating slide grooves 81, and the two rotating slide grooves 81 are arranged opposite to each other. A special-shaped extrusion ring block 82 is fixedly connected in the rotating slide groove 81. The special-shaped extrusion ring block 82 is provided with an inclined sliding surface 85 at one end close to the cable body 5. Fixed fan plates 83 are fixedly connected to the two opposite sides of the outer wall of the connecting frame 12.

The inclined sliding surfaces 85 provided on the two special-shaped extrusion ring blocks 82 have the same rotation direction, and the two arc-shaped push rods 84 respectively correspond to the deeper end of each inclined sliding surface 85.

[0038] Specifically, due to the action of water flow, the position of the connecting rod 91 may rotate or swing. When one end of the cable body 5 is close to the connecting platform 1, the arc-shaped top rod 84 is inserted into the rotating slide groove 81. If the angle of the arc-shaped top rod 84 changes, the special-shaped extrusion ring block 82 is a curved block, and the end of the special-shaped extrusion ring block 82 close to the arc-shaped top rod 84 is provided with an inclined sliding surface 85. When the arc-shaped top rod 84 collides with the special-shaped extrusion ring block 82, it will be squeezed by the inclined sliding surface 85 on the special-shaped extrusion ring block 82, causing the arc-shaped top rod 84, the connecting frame 12 and the connecting rod 91 to rotate to the initial position, so as to ensure that the connecting rod 91 can be inserted into the connecting groove 92, and the twisting of the cable body 5 can be prevented from causing damage to the cable body 5.

Then the docking station 1 and the fixing seat 2 are transferred to the opposite bank by a boat or other convenient means of transportation, and the fixing seat 2 is fixed on the bank. Then the driving motor 3 is started. The rotation of the driving motor 3 will drive the winding rod 13 to rotate, so that the traction rope 6 on the winding rod 13 is wound. Through the reciprocating movement of the electric push rod 4, the traction rope 6 can be evenly wound around the winding rod 13 during winding, thereby When the traction rope 6 and the cable body 5 are wound up, one end of the cable body 5 will move to the inner cavity of the docking station 1, and the plugging rod 91 will also be inserted into the plugging groove 92. Then the plugging rod 91 squeezes the bottom end of the upper support rod 93, so that the upper support rod 93 moves downward to prevent the upper end of the upper support rod 93 from squeezing the cable body 5. When the upper support rod 93 moves downward, the upper support rod 93 drives the fixed link 103 and the lifting rod 103 to move downward. The lowering frame 104 moves downward, so that the lifting frame 104 squeezes the sliding clamping rod 101 inward, so that the two sliding clamping rods 101 approach each other, and then the clamping head 102 clamps the cable body 5 located in the docking station 1. When the upper support rod 93 slides downward, one end of the plug-in rod 91 will be inserted into the plug-in hole 94, and then the squeezed trapezoidal stopper 95 pops up downward first, so that the plug-in rod 91 is clamped in the plug-in hole 94, preventing the cable body 5 from being pulled underwater when fixed due to the impact of water flow. Due to the effect of water flow, the position of the plug-in rod 91 may rotate or swing. When one end of the cable body 5 is close to When the arc push rod 84 is close to the plug-in platform 1, the arc push rod 84 is inserted into the rotating slide groove 81. If the angle of the arc push rod 84 changes, the special-shaped extrusion ring block 82 is a ring block, and the special-shaped extrusion ring block 82 is provided with an inclined sliding surface 85 at one end close to the arc push rod 84, then when the arc push rod 84 collides with the special-shaped extrusion ring block 82, it will be squeezed by the inclined sliding surface 85 on the special-shaped extrusion ring block 82, so that the arc push rod 84, the connecting frame 12 and the plug-in rod 91 are rotated to the initial position, so as to ensure that the plug-in rod 91 can be inserted into the plug-in slot 92, and the cable body 5 can be prevented from twisting and causing damage to the cable body 5.
