For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] See also Figures 1 to 4 As shown, according to an embodiment of the present application, an overhead ground wire hoisting device includes: a hoisting wheel 1, which is detachably mounted on the ground wire 9 to be lifted, and the hoisting wheel 1 is suitable for rotating with the axis of the ground wire 9 to be lifted as the rotation center; a traction rope, which includes a first end and a second end, the first end of the traction rope is relatively fixed to the pole tower, and the second end of the traction rope is connected to the hoisting wheel 1, and when the hoisting wheel 1 rotates, the hoisting wheel 1 winds up the traction rope.

[0023] The overhead ground wire hoisting device provided in the embodiment of the present application can achieve the purpose of lifting the ground wire 9 to be lifted by sleeved a hoisting wheel 1 on the ground wire 9 to be lifted, and making the hoisting wheel 1 able to coil the traction rope connected to the pole tower when rotating with the axis line of the ground wire 9 to be lifted as the rotation center; at the same time, the overhead ground wire hoisting device has a simple structure and is easy to operate, which can reduce the labor intensity of the staff and improve the safety of work; at the same time, the amplitude of the overhead ground wire hoisting device lifting the ground wire 9 to be lifted is affected by the connection position of the traction rope and the pole tower, and can be manually adjusted, thereby increasing the amplitude of the overhead ground wire hoisting device lifting the ground wire 9 to be lifted; at the same time, the overhead ground wire hoisting device is sleeved on the ground wire 9 to be lifted by the hoisting wheel 1 to drive the ground wire 9 to be lifted to move, so that the ground wire 9 to be lifted is evenly stressed in the circumferential direction, thereby avoiding damage to the ground wire 9 to be lifted.

[0024] Among them, the ground wire 9 to be lifted can be an overhead ground wire.

[0025] The hoisting wheel 1 is roughly annular, and a mounting hole is opened in the middle of the hoisting wheel 1. The mounting hole is used to pass the ground wire 9 to be lifted, so that the hoisting wheel 1 can be sleeved on the ground wire 9 to be lifted.

[0026] Specifically, after the hoisting wheel 1 is sleeved on the ground wire 9 to be lifted, the position of the hoisting wheel 1 on the ground wire 9 to be lifted is fixed. It should be noted that when the hoisting wheel 1 is displaced in space, it can drive the ground wire 9 to be lifted to move, so as to achieve the purpose of lifting and loosening the ground wire 9 to be lifted.

[0027] The traction rope may be a steel wire rope, and the traction rope includes a first end and a second end. The first end of the traction rope is used to connect to the pole tower, and the second end of the traction rope is used to connect to the lifting wheel 1.

[0028] Specifically, the first end of the traction rope can be hung on the cross arm at the top of the tower, and the second end of the traction rope can be wound around the hoisting wheel 1.

[0029] The hoisting wheel 1 is rotatably mounted on the ground wire 9 to be lifted.

[0030] Specifically, a rotating connector is provided in the mounting hole. After the hoisting wheel 1 is sleeved on the ground wire 9 to be lifted, the inner wall of the rotating connector can be interference fit with the outer wall of the ground wire 9 to be lifted, so that the position of the hoisting wheel 1 on the ground wire 9 to be lifted is fixed, and the outer wall of the rotating connector can be gap-fitted with the hole wall of the mounting hole, so that the hoisting wheel 1 can rotate relative to the ground wire 9 to be lifted. It should be noted that when the hoisting wheel 1 is sleeved on the ground wire 9 to be lifted and rotates, the hoisting wheel 1 winds the traction rope through the second end of the traction rope, and the hoisting wheel 1 moves toward the direction close to the first end of the traction rope, thereby driving the ground wire 9 to be lifted to move synchronously toward the direction close to the first end of the traction rope. Since the first end of the traction rope is located on the cross arm at the top of the pole tower, that is, when the hoisting wheel 1 winds the traction rope, it can drive the ground wire 9 to be lifted to move toward the direction of the cross arm close to the top of the pole tower, thereby achieving the purpose of lifting the ground wire 9 to be lifted.

[0031] It can be understood that when it is necessary to loosen the ground wire 9 to be lifted, the lifting wheel 1 is rotated in the opposite direction to loosen the traction rope wrapped around the lifting wheel 1. At this time, the lifting wheel 1 drives the ground wire 9 to be lifted in the direction away from the first end of the traction rope under the action of its own weight and the gravity of the ground wire 9 to be lifted, that is, the lifting wheel 1 drives the ground wire 9 to be lifted in the direction away from the cross arm at the top of the tower, thereby achieving the purpose of loosening the ground wire 9 to be lifted.

[0032] The hoisting wheel 1 is detachably mounted on the ground wire.

[0033] Specifically, as an embodiment, the hoisting wheel 1 is integrally formed; as another embodiment, the hoisting wheel 1 is split, and the hoisting wheel 1 is composed of two wheel bodies connected. In the embodiment of the present application, the hoisting wheel 1 is split, which can facilitate the installation of the hoisting wheel 1 on the ground wire 9 to be lifted, thereby improving work efficiency.

[0034] In some possible implementations disclosed in this application, see Figure 2 As shown, the rotating connecting member is a bearing 2, and the bearing 2 is arranged between the hoisting wheel 1 and the ground wire 9 to be lifted. The hoisting wheel 1 is sleeved on the ground wire 9 to be lifted through the bearing 2.

[0035] By arranging the bearing 2 between the hoisting wheel 1 and the ground wire 9 to be lifted, the friction between the hoisting wheel 1 and the ground wire 9 to be lifted can be reduced when the hoisting wheel 1 rotates, thereby avoiding damage to the ground wire 9 to be lifted.

[0036] The bearing 2 may be a ball bearing 2 or a roller bearing 2, etc., which can enable the hoisting wheel 1 to rotate relative to the ground wire 9 to be lifted, and this application does not make any further limitations.

[0037] Specifically, the bearing 2 is arranged between the inner wall of the hoisting wheel 1 and the outer wall of the ground wire 9 to be lifted, the inner wall of the bearing 2 and the outer wall of the ground wire 9 to be lifted are relatively fixed, and the outer wall of the bearing 2 and the inner wall of the hoisting wheel 1 are relatively fixed. A rolling ball or roller is arranged between the inner wall of the bearing 2 and the outer wall of the bearing 2, and when the hoisting wheel 1 rotates, the ball or roller moves.

[0038] A shaft sleeve may be provided between the outer wall of the bearing 2 and the inner wall of the winch wheel 1 to reduce wear and extend the service life of the winch wheel 1 .

[0039] In some possible implementations disclosed in this application, see Figure 1 As shown, the hoisting wheel 1 includes a first wheel body 11 and a second wheel body 12, and the first wheel body 11 and the second wheel body 12 are connected by a mortise and tenon structure.

[0040] By arranging the hoisting wheel 1 to include a first wheel body 11 and a second wheel body 12, and connecting the first wheel body 11 and the second wheel body 12 through a mortise and tenon structure, it is convenient to install the hoisting wheel 1 on the ground wire 9 to be lifted, thereby improving work efficiency.

[0041] The first wheel body 11 and the second wheel body 12 are roughly semicircular arc-shaped, and the first wheel body 11 and the second wheel body 12 are used to divide the hoisting wheel 1 and the mounting hole into two open parts.

[0042] Specifically, as an embodiment, the open side of the first wheel body 11 is provided with a mortise, and the open side of the second wheel body 12 is provided with a tenon; as another embodiment, the open side of the first wheel body 11 is provided with a tenon, and the open side of the second wheel body 12 is provided with a mortise. In the embodiment of the present application, the open side of the first wheel body 11 is provided with a limiting groove which can be used as a mortise, and the open side of the second wheel body 12 is provided with a limiting block which can be used as a tenon. When the first wheel body 11 and the second wheel body 12 are connected, the limiting block is embedded in the limiting groove, and the limiting groove is used to bite the limiting block.

[0043] The cross section of the limit block and the limit groove perpendicular to the central axis of the winch wheel 1 can be a trapezoid, and the lower bottom of the trapezoid coincides with the bottom surface of the limit groove. In the embodiment of the present application, when the winch wheel 1 is installed on the ground wire 9 to be lifted, the first wheel body 11 can be hung on the ground wire 9 to be lifted, and then the second wheel body 12 can be moved along the axial direction of the winch wheel 1 until the limit block is embedded in the limit groove.

[0044] In some possible implementations disclosed in this application, see Figure 1 As shown, the overhead ground wire hoisting device further includes a driving rod 3 , and the driving rod 3 is arranged on the outer wall of the axial side of the hoisting wheel 1 .

[0045] By arranging a driving rod 3 on the outer wall of the axial side of the lifting wheel 1, the driving rod 3 can be rotated around the ground wire 9 to be lifted so that the traction rope can be wound around the lifting wheel 1, thereby lifting the ground wire 9 to be lifted.

[0046] The driving rod 3 may be a long metal rod or the like.

[0047] Specifically, the driving rod 3 is arranged on the side wall of the lifting wheel 1 along the axial direction of the lifting wheel 1 .

[0048] The driving rod 3 is parallel to the axis of the ground wire 9 to be lifted, and the driving rod 3 can be used as a crank for rotating the lifting wheel 1.

[0049] In addition, the driving rod 3 can also be arranged as follows: See also Figure 1 As shown, the driving rod 3 is perpendicular to the axis of the ground wire 9 to be lifted. At this time, the driving rod 3 can be used as a force arm for rotating the lifting wheel 1.

[0050] Specifically, in the embodiment of the present application, the driving rod 3 is perpendicular to the axis of the ground wire 9 to be lifted, and the driving rod 3 is fixed to the lifting wheel 1 by a locking buckle 8.

[0051] The lock buckle 8 is roughly U-shaped, with a convex portion for accommodating the driving rod 3 in the middle of the lock buckle 8, and bolt holes are provided at both ends of the lock buckle 8. In the embodiment of the present application, two lock buckles 8 are provided, and the two lock buckles 8 are arranged opposite to each other along the length direction of the driving rod 3. The convex portions of the two lock buckles 8 cover the driving rod 3 at the same time, and bolts are inserted into the bolt holes at both ends of the two lock buckles 8 to press the driving rod 3.

[0052] In some possible implementations disclosed in this application, see Figure 2 As shown, an arc-shaped groove 4 is provided on the outer edge of the hoisting wheel 1, and the traction rope is slidably arranged in the arc-shaped groove 4.

[0053] The arc groove 4 provides a stable setting position for the traction rope, and at the same time can limit the traction rope in the axial direction of the hoisting wheel 1 to prevent the traction rope from falling off the hoisting wheel 1, thereby improving the working stability of the overhead ground wire hoisting device.

[0054] The cross-sectional shape of the arc groove 4 can be a semicircular arc.

[0055] Specifically, the arc groove 4 is opened along the radial direction of the lifting wheel 1 at the outer edge of the lifting wheel 1 away from the ground wire 9 to be lifted, and extends along the circumferential direction of the lifting wheel 1.

[0056] In some possible implementations disclosed in this application, see Figure 1As shown, a through hole 5 is formed on the hoisting wheel 1, and the through hole 5 passes through the arc groove 4 along the axial direction of the hoisting wheel 1. The second end of the traction rope is suitable for passing through the through hole 5 and being fixed.

[0057] By opening a through hole 5 on the hoisting wheel 1 , the second end of the traction rope wound in the arc groove 4 can extend through the through hole 5 and be fixed on the outer wall of the hoisting wheel 1 .

[0058] The through hole 5 may be circular, and the diameter of the through hole 5 may be larger than the diameter of the traction rope, so that the traction rope can pass through the through hole 5 .

[0059] Specifically, the through opening 5 is formed on the outer wall of the lifting wheel 1 and penetrates one side wall of the arc groove 4 along the axial direction of the lifting wheel 1 , so that the traction rope in the arc groove 4 can be led out through the through opening 5 .

[0060] Among them, the second section 72 of the traction rope can be fixed by the lock buckle 8 after being led out through the through hole 5. The lock buckle 8 is roughly U-shaped, and the middle part of the lock buckle 8 has a convex part for accommodating the traction line, and bolt holes are provided at both ends of the lock buckle 8. In the embodiment of the present application, after the second end of the traction rope is led out through the through hole 5, it is inserted into the convex part of the lock buckle 8, and then the lock buckle 8 is fixed to the lifting wheel 1 by bolts through the bolt holes at both ends of the lock buckle 8, thereby tightening the traction rope. It should be noted that in the present application, the connection between the traction rope and the lifting wheel 1 is detachable to achieve the separate storage of the lifting wheel 1 and the traction rope, so as to facilitate the carrying of the overhead ground wire lifting device.

[0061] In some possible implementations disclosed in this application, see Figure 1 and Figure 2 As shown, a self-locking hole 6 is also provided on the hoisting wheel 1, and the self-locking hole 6 passes through the arc groove 4 along the axial direction of the hoisting wheel 1. The self-locking hole 6 is used to pass a self-locking pin 7, and the self-locking pin 7 is used to apply a radial force to the traction rope to increase the friction between the traction rope and the arc groove 4.

[0062] By opening a self-locking hole 6 on the lifting wheel 1 and passing a self-locking pin 7 through the self-locking hole 6, a radial force can be applied to the traction rope wound in the arc groove 4, thereby increasing the friction between the traction rope and the arc groove 4, forming self-locking, and fixing the ground wire 9 to be lifted at the target height.

[0063] The self-locking hole 6 may be circular.

[0064] Specifically, the self-locking hole 6 is also provided on the outer wall of the lifting wheel 1 , and simultaneously penetrates the groove walls on both sides of the arc groove 4 along the axial direction of the lifting wheel 1 .

[0065] The self-locking hole 6 is used to pass the self-locking pin 7, and the self-locking pin 7 can be a pin or the like.

[0066] Specifically, when the self-locking pin 7 passes through the self-locking hole 6, the self-locking pin 7 can apply radial pressure to the traction rope wound in the arc groove 4 to increase the friction between the traction rope and the arc groove 4. It should be noted that when the hoisting wheel 1 is rotated to lift the ground wire 9 to be lifted to the target height, the ground wire 9 to be lifted applies a vertical downward pulling force to the traction rope through the hoisting wheel 1, and the traction rope is also subjected to the horizontal friction force provided by the arc groove 4. At this time, the traction rope is self-locked under the action of the vertical downward pulling force and the horizontal friction force. In certain extreme cases, the self-locking pin 7 passing through the self-locking hole 6 can also limit the traction rope in the opposite direction of the winding direction of the traction rope to ensure that the ground wire 9 to be lifted is stably fixed at the target height.

[0067] In some possible implementations disclosed in this application, see Figure 1 As shown, the self-locking holes 6 are provided in a plurality, and the distances between the self-locking holes 6 and the axial center line of the ground wire 9 to be lifted are different.

[0068] The ground wire 9 to be lifted can be fixed at different heights by providing a plurality of self-locking holes 6 and making the distances between the plurality of self-locking holes 6 and the axial center line of the ground wire 9 to be lifted different.

[0069] When the ground wire 9 to be lifted is lifted to different heights, the number of traction coils wound on the lifting wheel 1 is different, that is, the thickness of the traction wire coils in the arc groove 4 is different. In the present application, by providing a plurality of self-locking holes 6 and making the distances between the plurality of self-locking holes 6 and the axis of the ground wire 9 to be lifted different, the traction wire coils with different rear views can be compressed, thereby achieving the purpose of fixing the ground wire 9 to be lifted at different heights.

[0070] In some possible implementations disclosed in this application, see Figure 3 As shown, the self-locking pin 7 includes a first section 71 and a second section 72, and the second section 72 is rotationally connected to the first section 71. The working state of the self-locking pin 7 includes a first state and a second state. When the self-locking pin 7 is working in the first state, the second section 72 is parallel to the first section 71. When the self-locking pin 7 is working in the second state, the second section 72 is perpendicular to the first section 71.

[0071] By setting the second section 72 to be rotatably connected with the first section 71, the self-locking pin 7 can be limited in the axial direction of the lifting wheel 1 by rotating the second section 72 after passing through the self-locking hole 6, thereby preventing the self-locking pin 7 from escaping from the self-locking hole 6 and ensuring that the ground wire 9 to be lifted can be fixed at the target height.

[0072] The self-locking pin 7 includes a first section 71 and a second section 72 which are rotatably connected. The first section 71 and the second section 72 may be cylindrical long rods.

[0073] Specifically, the working state of the self-locking pin 7 includes a first state and a second state. When the self-locking pin 7 is in the first state, the first section 71 is parallel to the second section 72, so that the self-locking pin 7 can smoothly pass through the self-locking hole 6; when the self-locking pin 7 is in the second state, the second section 72 is perpendicular to the first section 71, and the second section 72 is used to limit the first section 71 in the opposite direction of the moving direction when the self-locking pin 7 passes through the self-locking hole 6.

[0074] Among them, the end of the first section 71 away from the second section 72 is a pin head, the diameter of the pin head is larger than the inner diameter of the self-locking hole 6, and the pin head is used to limit the first section 71 in the moving direction when the self-locking pin 7 passes through the self-locking hole 6.

[0075] The overhead ground wire hoisting device provided in the embodiment of the present application can achieve the purpose of lifting the ground wire 9 to be lifted by sleeved a hoisting wheel 1 on the ground wire 9 to be lifted, and making the hoisting wheel 1 able to coil the traction rope connected to the pole tower when rotating with the axis line of the ground wire 9 to be lifted as the rotation center; at the same time, the overhead ground wire hoisting device has a simple structure and is easy to operate, which can reduce the labor intensity of the staff and improve the safety of work; at the same time, the amplitude of the overhead ground wire hoisting device lifting the ground wire 9 to be lifted is affected by the connection position of the traction rope and the pole tower, and can be manually adjusted, thereby increasing the amplitude of the overhead ground wire hoisting device lifting the ground wire 9 to be lifted; at the same time, the overhead ground wire hoisting device is sleeved on the ground wire 9 to be lifted by the hoisting wheel 1 to drive the ground wire 9 to be lifted to move, so that the ground wire 9 to be lifted is evenly stressed in the circumferential direction, thereby avoiding damage to the ground wire 9 to be lifted.

[0076] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0077] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
