Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to disclose a V-shaped wire-turning frame, which is implemented using the following technical solution.

[0006] A V-shaped wire-turning frame includes a frame body, which is composed of two side rods. The lower ends of the two side rods are pivotally connected in a V-shape. Each side rod has a lifting guide rod and a connecting component at its upper end. The two lifting guide rods are symmetrical. Each lifting guide rod consists of two clamping rods and a sliding lifting rod. The upper ends of the two clamping rods and the upper end of the sliding lifting rod are fixed in a U-shape. The sliding lifting rod is located between the two clamping rods. The side rods are fixed to the corresponding connecting components and can be disassembled. The sliding lifting rod is slidably connected to the connecting components. A limiting crossbar is provided in the middle of the two side rods to fix the position of the two side rods. The plane formed by the axes of the two side rods of the frame body is perpendicular to the plane formed by the axes of the two clamping rods of the lifting guide rod.

An anti-detachment device is provided on the side rod below the pulley assembly. The anti-detachment device is connected to the lower end of the sliding rod via a steel wire rope. When the steel wire rope is subjected to the tension of the sliding rod, the anti-detachment device opens, and the pulley groove on the lower side of the pulley can be placed on the cable. When the steel wire rope is not subjected to the tension of the sliding rod, the anti-detachment device closes to prevent it from detaching from the cable.

[0007] The V-shaped wire turning frame described above includes a pulley assembly comprising multiple identical pulleys, an inner side plate, and a guard plate. The axles of the multiple pulleys are fixed between the inner side plate and the guard plate. The axles of all pulleys in the two pulley assemblies are located on the same horizontal straight line. The inner side plate is fixed to the corresponding side rod.

[0008] The aforementioned V-shaped wire-turning frame includes a safety buckle and a torsion spring as its anti-fall device. The safety buckle is located on the corresponding side bar below the guard plate. The lower end of the safety buckle is pivotally connected to the side bar via a rotating shaft. A torsion spring is fitted on the rotating shaft. When the safety buckle is not under the tension of the wire rope, the upper end of the safety buckle abuts against the guard plate. The safety buckle corresponding to the same side bar and the lower end of the sliding rod are connected by a taut wire rope.

[0009] The aforementioned V-shaped wire-turning frame has a wire rope guide ring on the side bar above the safety buckle, through which the wire rope passes.

[0010] The aforementioned V-shaped wire turning frame has a lower end of the guard plate below the lower end of the pulley, and the guard plates of the two pulley assemblies are fixed to a detachable guide rod, which is inclined downwards.

[0011] The aforementioned V-shaped wire turning frame has a detachable guide rod in a V-shape.

[0012] The V-shaped wire turning frame described above has a detachable guide rod whose two ends are fixed to and detachable with the corresponding guard plate.

[0013] The aforementioned V-shaped wire-turning frame also has a buckle pivotally connected to the lower ends of the two side rods.

[0022] Example: Figures 1 to 4 A V-shaped wire-turning frame includes a frame body 8, which is composed of two side rods. The lower ends of the two side rods are pivotally connected in a V-shape, and a buckle is also pivotally connected to the lower ends of the two side rods. Each of the two side rods has a lifting guide rod 1 and a sleeve component at its upper end. The two lifting guide rods 1 are symmetrical. Each lifting guide rod 1 consists of two clamping rods and a sliding lifting rod 2. The upper ends of the two clamping rods and the upper end of the sliding lifting rod 2 are fixed in a U-shape. The sliding lifting rod 2 is located at... Between the two clamping rods, the side rods are sleeved with the corresponding sleeve components and fixed with bolts. The sliding rod 2 is slidably sleeved with the sleeve components. The lower end of the sliding rod 2 is provided with an adjustable screw 3. A limiting crossbar 5 is provided in the middle of the two side rods to fix the position of the two side rods. The plane formed by the axes of the two side rods of the flipping frame body 8 is perpendicular to the plane formed by the axes of the two clamping rods of the lifting guide rod 1. The angle bisector of the angle formed by the sliding rod 2 and the two side rods of the flipping frame body 8 is parallel. Each of the two side rods is equipped with a pulley assembly, which includes two identical pulleys, an inner side plate, and a guard plate 11. The shafts of the two pulleys are fixed between the inner side plate and the guard plate 11. The axes of the four pulleys are located on the same horizontal line. The inner side plate is fixed to the corresponding side rod. The lower end of the guard plate 11 is lower than the lower end of the pulley. The guard plate 11 of the two pulley assemblies is fixed to a detachable guide rod 7. The detachable guide rod 7 is V-shaped. Both ends of the detachable guide rod 7 are fixed to the corresponding guard plate 11 and are detachable. The detachable guide rod 7 is inclined downward. A safety buckle is provided on the side rod below the guard plate 11. The lower end of the safety buckle is pivotally connected to the side rod via a rotating shaft. A torsion spring is fitted on the rotating shaft. When the safety buckle is not under the tension of the wire rope 4, the upper end of the safety buckle abuts against the guard plate 11. A wire rope guide ring 12 is provided on the side rod above the safety buckle. The safety buckle and the adjustable screw 3 corresponding to the same side rod are connected by a taut wire rope 4. The wire rope 4 passes through the wire rope guide ring 12.

[0023] During operation, a horizontal bar is hoisted using a drone. The drone controls the bar to simultaneously engage between the sliding rods 2 of the two hoisting guide rods 1 and an adjacent locking rod. After engagement, the drone lifts the bar upwards, causing the hoisting guide rods 1 to move upwards. The sliding rods 2 pull the wire rope 4, which in turn pulls the safety buckle 10, disengaging it from the guard plate 11. The drone then flies the cable-lifting frame to the cable to be suspended in the air. The lower tracks of the four pulleys are then attached to the cable. The drone lowers its altitude and flies away from the V-shaped cable-lifting frame. The hoisting guide rods 1 reposition themselves, the tension on the wire rope 4 from the hoisting guide rods 1 disappears, and the safety buckle 10 resets and locks the cable, preventing the cable-lifting frame from falling off.

[0024] When removing the V-shaped cable tray, simply have the drone control bar simultaneously engage between the sliding boom 2 of the two lifting guide rods 1 and an adjacent clamping rod. After engaging, the drone lifts the bar upwards, which in turn lifts the lifting guide rods 1 upwards. The sliding boom 2 pulls the wire rope, which in turn pulls the safety buckle 10, causing the safety buckle 10 to disengage from the guard plate 11. Then, control the drone to transport the V-shaped cable tray away from the cable.

[0025] This application has the following beneficial effects: 1. Temporary support and guidance - During construction, support the cable in the V-groove between the two side poles to prevent slippage and dragging on the ground; guide the cable route, control the bending radius, and avoid hard bends and damage to insulation.

[0026] 2. Flip-up and repositioning - The cable flip-up frame can rotate 90° around the axis of the cable used for suspension: the cable flips from "horizontally supported" to "side-mounted", which is convenient for passing through pipes, crossing bridges, and crossing obstacles. It can be used for special cable hanging such as corner towers; there is no need to repeatedly lift and move the cable, saving manpower and preventing twisting.

[0027] 3. Protect cables and insulation - V-groove with nylon / bakelite rollers, low sliding friction, no damage to wires or scratches to insulation; avoids damage and strand breakage caused by dragging cables directly on the ground, angle steel, or concrete.

[0028] 4. Improve cable laying / tightening efficiency - Cables move via guide wheels, making it suitable for straight lines, corners, and crossings, ensuring smooth cable routing without jamming or tangling; multiple sets can be connected in series, suitable for long-distance, large-section cable construction.

[0029] 5. Safety Isolation - During overhead / underground construction, cables are passed through clips to keep them off the ground / ditch wall, reducing the risk of pedestrians stepping on them, vehicles running over them, or being punctured by sharp objects.

[0030] 6. When re-laying cables, drones can be used to suspend the re-laying frame on the existing cables. Compared with using cranes or building temporary cross-line frames, this method is lower in cost, more efficient, and less restricted by terrain conditions.

[0031] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
