Description

Technical Field

[0002] With the development of the economy and the improvement of people's living standards, people have higher and higher requirements for the power system, and the electricity consumption demand is also increasing day by day. In order to solve the increasing electricity consumption demand of people, the power system continuously builds transmission lines. However, various obstacles will be encountered during the erection of transmission lines. Newly built transmission lines often intersect with existing high-voltage transmission lines or highways and other objects to be spanned geographically. In order to meet people's electricity consumption needs, reduce the losses of the power system, and ensure people's daily life, during the construction of transmission lines, power construction units generally adopt the spanning frame line construction technology.

Step 2: Then, pass the rope through the first limiting ring at the top of the upright frame, around the upper side of the bearing wheel, and under the pressing wheel, and then connect it to the support rod on the bearing seat. Step 3: Then, start the first servo motor to gradually tension the ropes on both sides of the insulating plate until the ropes are lifted to a certain height, and at this time, the clamping plate is clamped at the corresponding locking tooth position. At the same time, start the second winding motor to tension the towing rope, and ensure that the fixing plate is located near the upright frame. Step 4, then start to place the laying module on the rope, make sure that the rope passes through the limit assembly, and then start the winding motor 1 and the winding motor 2 at the same time, so that the contact plate on the traction rope touches the second contact switch, and the microcontroller supplies power to the electromagnet 2, and the electromagnet 2 generates suction to the metal plate 2 to move it upward, and the movable splint clamps the traction rope at this time; as the traction rope continues to move, the laying module gradually approaches the insulating plate, and when the trigger rod on the insulating plate contacts the first contact switch, the microcontroller cuts off the power to the electromagnet 2 and supplies power to the electromagnet 1, so that the electromagnet 1 is adsorbed with the metal plate 1 on the insulating plate, and then controls the winding motor 1 and the winding motor 2 to flip, so that the contact plate moves to a position close to the stand; Step 5: Repeat step 4 to gradually lay the laying modules on the ropes, and the laying of the ropeway is completed; Step 6: After the laying module is laid, the screw rod 2 in the fixing mechanism is rotated so that the pressing plate 2 presses the traction rope, and then the screw rod 1 in the first transmission assembly is rotated so that the pressing plate 1 squeezes the traction rope and is close to the friction wheel; Step 7, when the cableway sinks due to load or other reasons, a part of the traction rope is pulled out from the winding roller 1. When the traction rope is pulled out, the friction wheel rotates, and then the active bevel gear rotates, which drives the driven bevel gear 1 in the second transmission assembly to rotate, and then the driven bevel gear 2 drives the driven bevel gear 3, and the driven bevel gear 3 drives the rotating shaft to rotate, so that the bearing seat moves away from the stand, thereby increasing the tension of the rope and reducing the sinking amplitude of the cableway. When the height of the cableway is stable, the winding motor 1 is started through the control module to tighten the traction rope again; Step 8, when it is necessary to dismantle the crossing frame, first make the pressing plate 1 and the pressing plate 2 away from the traction rope, then control the winding motor 1 and the winding motor 2 to rotate, so that the contact plate contacts the second contact switch, at this time, the microcontroller energizes the electromagnet 2, and the movable clamp clamps the traction rope, and at the same time, the microcontroller cuts off the power to the electromagnet 1 in the corresponding laying module, and then controls the winding motor 1 and the winding motor 2 to rotate in the opposite direction, and moves the laying module to the position close to the stand through the traction rope, and then manually operates the microcontroller to cut off the power to the electromagnet 2, and lifts the limit plate by pulling the pull ring, and then the rope is separated from the traction rope; in this way, the laying modules are removed one by one; Step 9, control servo motor 2 to rotate a certain amplitude to disengage the card plate from the card teeth, and at the same time control servo motor 1 to rotate to release the rope so that the insulating plate falls to the ground, and then manually remove the rope from the support rod, and then control servo motor 1 to rotate to reel the rope.

[0015] The present invention has outstanding substantive features and significant progress compared to the prior art. Specifically, the present invention has the following advantages: The novel spanning frame and its erection method provided by the present invention are not only designed to facilitate the rapid erection of the spanning frame, but also can drive the tension adjustment mechanism through the change of the length of the traction rope when the cableway sags due to the impact of heavy objects, so as to make the rope continue to be tightened, prevent the cableway from sagging excessively, and ensure that it is at a safe height. Moreover, it is convenient to disassemble the spanning frame after use, and the overall structure design of the spanning frame is very ingenious and highly practical.

[0038] According to the above-mentioned novel spanning frame, its erection method includes the following steps: Step 1: First, place two support components at appropriate positions on both sides of the obstacle to be spanned, and adjust the position of the bearing seat 6 so that it is located near the vertical frame 2; Step 2: Then, pass the rope 34 through the first limiting ring 22 at the top of the vertical frame 2, around the upper part of the bearing wheel, and under the pressing wheel 12, and then connect it to the support rod 9 on the bearing seat 6; Step 3: Then, start the first servo motor 30 to gradually tension the ropes 34 on both sides of the insulating plate 29 until the ropes 34 are lifted to a certain height, and at this time, the clamping plate 36 is clamped at the corresponding tooth position; At the same time, start the second winding motor to make the traction rope 25 taut, and ensure that the fixing plate is in a position close to the vertical frame 2; Step 4: Then, start to place the laying module 43 on the rope 34, ensure that the rope 34 passes through the limiting component 43-9, and then start the first winding motor and the second winding motor at the same time, so that the contact plate 43-16 on the traction rope 25 touches the second contact switch 43-15. At this time, the microcontroller 43-4 supplies power to the second electromagnet 43-10. The second electromagnet 43-10 generates a suction force on the second metal plate 43-11 to make it move upward. At this time, the movable clamping plate 43-14 clamps the traction rope 25; As the traction rope 25 continues to move, the laying module 43 gradually approaches the insulating plate 29. When the trigger rod 43-7 on the insulating plate 29 touches the first contact switch 43-8, the microcontroller 43-4 cuts off the power supply to the second electromagnet 43-10 and supplies power to the first electromagnet 43-5, so that the first electromagnet 43-5 adsorbs together with the first metal plate 43-6 on the insulating plate 29, and then controls the first winding motor and the second winding motor to reverse, so that the contact plate 43-16 moves to a position close to the vertical frame 2; Step 5: Repeat Step 4 to gradually lay the laying module 43 on the rope 34, and the cableway laying is completed; Step 6: After the laying module 43 is laid, the screw rod 27-2 in the fixing mechanism 27 is rotated so that the pressing plate 27-4 presses the traction rope 25, and then the screw rod 1 26-5 in the first transmission assembly 26 is rotated so that the pressing plate 1 26-6 squeezes the traction rope 25 and makes it close to the friction wheel 26-3; Step 7, when the cableway sinks due to load or other reasons, a part of the traction rope 25 is pulled out from the winding roller 1. When the traction rope 25 is pulled out, the friction wheel 26-3 rotates, and then the active bevel gear 26-8 rotates, which drives the driven bevel gear 1 28-2 in the second transmission assembly 28 to rotate, and then the driven bevel gear 2 28-3 drives the driven bevel gear 3 5-1, and the driven bevel gear 3 5-1 drives the rotating shaft 5 to rotate, so that the bearing seat 6 moves away from the stand 2, thereby increasing the tension of the rope 34 and reducing the sinking amplitude of the cableway. When the height of the cableway is stable, the winding motor 1 is started through the control module 44 to tighten the traction rope 25 again; Step 8, when it is necessary to dismantle the crossing frame, first make the pressure plate 1 26-6 and the pressure plate 2 27-4 away from the traction rope 25, then control the winding motor 1 and the winding motor 2 to rotate, so that the contact plate 43-16 contacts the second contact switch 43-15, at this time, the microcontroller 43-4 energizes the electromagnet 2 43-10, and the movable clamp 43-14 clamps the traction rope 25, and at the same time, the microcontroller 43-4 cuts off the power to the electromagnet 1 43-5 in the corresponding laying module 43, and then controls the winding motor 1 and the winding motor 2 to rotate in the opposite direction, and moves the laying module 43 to a position close to the stand 2 through the traction rope 25, and then manually operates the microcontroller 43-4 to cut off the power to the electromagnet 2 43-10, and lifts the limiting plate 43-9-3 by pulling the pull ring 43-9-6, and then the rope 34 is separated from the traction rope 25; in this way, the laying modules 43 are removed one by one; Step 9, control the servo motor 2 42 to rotate a certain amplitude so that the card plate 36 is disengaged from the card teeth, and at the same time control the servo motor 1 30 to rotate to release the rope 34 so that the insulating plate 29 falls to the ground, and then manually remove the rope 34 from the support rod 9, and then control the servo motor 1 30 to rotate to reel the rope 34.
