Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, in particular to a quick-install traction net sleeve. Background Art

[0002] A traction mesh is a fixed connection device used to assist cable movement. It is typically made of high-strength braided material (such as steel wire). Its core function is to wrap around the surface of an object and tighten it, using friction to tightly adhere to the object, thereby maintaining stability under tension or vibration. However, existing technologies have the following shortcomings:

[0003] Material fatigue and slippage: Long-term stress or vibration will cause local relaxation of the mesh braid structure. Especially in dynamic load environments (such as transportation bumps and mechanical vibrations), the friction force will gradually weaken over time, resulting in reduced fixing effect;

[0004] Environmental factors: Humidity, corrosive gases or high temperature environments accelerate material aging, further weakening its tensile strength and fixing reliability.

[0005] To compensate for the above defects, the existing technology often uses iron wire (such as galvanized iron wire or stainless steel wire) tied to the outside of the mesh as a secondary fixing method, but this method has the following problems:

[0006] Wire bundling requires multiple steps, including threading, tightening, and knotting. Each set of operations takes about 3-5 minutes. This complex operation process will reduce work efficiency. However, if the winding is uneven or the knot is unreliable, the fixing effect will be reduced, and even the risk of failure will be accelerated under stress. Summary of the Invention

[0007] In order to solve the problems mentioned in the above background technology, the present invention provides a quick-install traction net.

[0008] The technical implementation scheme of the present invention is: a quick-install traction net, including a connecting column, the two ends of the connecting column are respectively fixed with a net body and a towing rope, and the outside of the net body is provided with a plurality of swing plates and a plurality of hinged plates, the hinged plate is located between two adjacent swing plates and is hinged to both, the swing plate is used to squeeze and fix the net body, the swing plate is provided with a through hole, and the net body is located in the through hole.

[0009] Furthermore, the central axis of the through hole is collinear with the central axis of the connecting column, and the central axis of the through hole is cross-distributed with the center line of the adjacent swing plate.

[0010] Furthermore, the connecting column is fixedly connected to a fixing cover located in the mesh sleeve body, and the fixing cover is used to squeeze the cable.

[0011] Furthermore, the edge line of the cross section of the fixed cover is a circular wavy line.

[0012] Furthermore, evenly distributed connecting ropes are fixed in the fixed cover, and the evenly distributed connecting ropes are used to shape and support the fixed cover.

[0013] Furthermore, a fixed shell is fixedly connected to the side of the mesh body away from the connecting column, a rotating shell is rotatably connected inside the fixed shell, the rotating shell is fixedly connected to the side of the fixed cover away from the connecting column, and a torsion spring is fixed between the fixed shell and the rotating shell.

[0014] Furthermore, the fixed shell is fixedly connected with evenly distributed fixed frames, the swing plates close to the fixed shell rotate along the evenly distributed fixed frames, and the remaining swing plates slide and rotate along the evenly distributed fixed frames.

[0015] Furthermore, the fixed frame is fixed with a wire sleeve, a wire core is slidably connected inside the wire sleeve, one end of the wire core passes through the fixed shell and is fixed to the rotating shell, the fixed frame is slidably connected to a rope fixed to the swing plate away from the fixed shell, the connecting column is slidably connected to a sliding frame, and the sliding frame is fixed to the rope.

[0016] Furthermore, the swing plate away from the fixed housing is fixedly connected to the other end of the wire core.

[0017] Furthermore, the connecting column is slidably connected to a limiting frame for limiting the sliding frame.

[0018] Compared with the existing technology, the present invention has the following advantages: the present invention proposes a new fixing method based on the inclined plate clamping, which implements an oblique clamping effect on the mesh and the cable through the inclined plate. The oblique traction force generated by the inclined plate on the mesh forces the mesh to fit tightly to the cable surface, thereby achieving rapid assembly and locking. Compared with the traditional secondary fixing method of binding with wire, this solution has the following advantages:

[0019] No need for threading, tightening or knotting operations, the net and cable can be fixed in a short time;

[0020] Before pulling the cable, the thickness of the fixing cover between the mesh body and the cable is increased through the torsional deformation of the fixing cover, thereby increasing the friction between the fixing cover and the mesh body and increasing the clamping force of the mesh body on the cable to reduce the probability of loosening.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0032] In order to solve the problems of low efficiency, high cost and insufficient fixing reliability caused by manual bundling of wires in the prior art, the present invention proposes a fixing structure based on an inclined plate clamping, which uses an inclined plate to obliquely clamp the mesh and cable, so that the inclined plate generates an oblique drag force on the mesh and cable, prompting the mesh to fit the cable, thereby realizing rapid assembly and fixation of the mesh and cable, and maintaining stability under dynamic loads.

[0033] A quick-install traction net, such as Figures 1-6As shown, it includes a connecting column 1, the lower and upper ends of the connecting column 1 are respectively fixed with a net body 2 and a drag rope 3, the materials of the net body 2 and the drag rope 3 can be steel wire, and the outside of the net body 2 is provided with a plurality of swing plates 4 and a plurality of hinged plates 5, the hinged plate 5 is located between two adjacent swing plates 4 and is hinged to both, the swing plate 4 is used to squeeze and fix the net body 2, the swing plate 4 is provided with a through hole 401, the net body 2 is located in the through hole 401, the swing plate 4 can be made of steel, and balls can be installed on the outside of the swing plate 4 to reduce the friction when all the swing plates 4 move. When it is necessary to pull the cable, the net body 2 fits with the end of the cable. At this time, the swing plate 4 is swung so that the swing plate 4 squeezes the net body 2 in an inclined manner to increase the friction between the net body 2 and the cable. In this device, there are four swing plates 4 and three hinged plates 5. This number is only for example. The staff can adjust the specific number of the swing plates 4 and the hinged plates 5 in actual application.

[0034] like Figure 6-Figure 9 As shown, several swing plates 4 are inclined, the central axis of the through hole 401 is collinear with the central axis of the connecting column 1, and the central axis of the through hole 401 is cross-distributed with the central axis of the adjacent swing plate 4. When the cable does not need to be fixed, the central axis of the through hole 401 is collinear with the central axis of the connecting column 1 to facilitate the installation of the hinged plate 5 and the swing plate 4. The connecting column 1 is fixed with a fixed cover 6 located in the mesh body 2. The fixed cover 6 is used to squeeze the cable. The fixed cover 6 can be a composite fabric to increase the friction between the mesh body 2 and the cable. The edge line of the cross section of the fixed cover 6 is a circular wavy line, so that the fixed cover 6 is loose before it is put on the cable. The upper part of the rotating shell 8 is a transition part, attached Figure 9 The collar between the fixed cover 6 and the rotating shell 8 is a transition portion for connecting the fixed cover 6 and the rotating shell 8. Evenly distributed connecting ropes 601 are fixed inside the fixed cover 6. The evenly distributed connecting ropes 601 are all used to shape and support the fixed cover 6. The connecting ropes 601 can be steel wires.

[0035] like Figure 5-Figure 9The cam 8 is fixed to the bottom of the cam 8 and is fixed to the bottom of the cam 8. The swing plates 4 all slide linearly along the two fixed frames 9 and rotate circumferentially. The fixed frame 9 is fixed with a wire sleeve 10. The wire sleeve 10 is slidably connected with a wire core 11. The wire core 11 passes through the fixed shell 7 and is wound around the rotating shell 8 and is fixed to the rotating shell 8. The swing plate 4 on the upper side is fixed to the upper end of the wire core 11. The fixed frame 9 is slidably connected to a rope 12 fixed to the swing plate 4 on the upper side. The connecting column 1 is slidably connected to a sliding frame 13. The sliding frame 13 is fixed to the rope 12. The upper side of the wire core 11 is connected to the fixed frame 9. The mounting frame is fixedly connected to the second swing plate 4 located on the upper side. The rope 12 can be a steel wire. The connecting column 1 is slidably connected to a limit frame 14 for limiting the sliding frame 13. The upper and lower sides of the sliding frame 13 are respectively provided with two rectangular holes distributed front and back. When the limit frame 14 is inserted into the two rectangular holes on the upper side of the sliding frame 13, the two ropes 12 are in an unpulled state. When the limit frame 14 is inserted into the two rectangular holes on the lower side of the sliding frame 13, the two ropes 12 are in a pulled state.

[0036] Working principle: When it is necessary to use this device to pull the cable, the staff inserts the cable end into the fixed cover 6. When the cable end enters the fixed cover 6, the staff first pulls out the limit frame 14 until it is no longer in contact with the connecting column 1 and the sliding frame 13, and then pulls the sliding frame 13 upward to move the sliding frame 13 upward along the connecting column 1. During the movement of the sliding frame 13, the two ropes 12 are pulled so that the two ropes 12 slide along the adjacent fixed frames 9 respectively and pull the adjacent swing plates 4 upward. The swing plate 4 on the upper side swings during the process of moving straight upward along the two fixed frames 9, so that the central axis of the through hole 401 gradually crosses the central axis of the fixed cover 6.

[0037] During the upward movement of the upper swing plate 4, the adjacent hinged plate 5 pulls the lower swing plate 4 to move upward in a straight line along the two fixed frames 9. Excluding the swing plate 4 on the lower side, the remaining swing plates 4 slide and swing circumferentially along the two fixed frames 9 under the pull of the adjacent hinged plates 5. Through the swinging of all the above-mentioned swing plates 4, the central axes of all through holes 401 and the central axis of the fixed cover 6 are kept in a cross-distributed state (the swing plate 4 on the lower side rotates, and the other three swing plates 4 rotate and slide at the same time). With the continuous pulling of the rope 12, the interior of all the swing plates 4 gradually squeezes the mesh body 2, so that the mesh body 2 is forced to fit the cable, thereby increasing the friction between the mesh body 2 and the cable.

[0038] The two wire cores 11 are moved along the two wire sleeves 10 respectively, so that the two wire cores 11 pull the rotating shell 8, and then the rotating shell 8 rotates clockwise along the fixed shell 7 (clockwise when viewed from top to bottom, the torsion spring between the two is gradually tightened during the rotation of the rotating shell 8 along the fixed shell 7). During the rotation of the rotating shell 8, the lower side of the fixed cover 6 and all the connecting ropes 601 is twisted, so that the fixed cover 6 and all the connecting ropes 601 are in a twisted state as a whole. After the fixed cover 6 is twisted, it approaches the cable and hugs the cable, thereby increasing the friction between the fixed cover 6 and the cable, and at the same time increasing the thickness of the fixed cover 6 between the mesh sleeve body 2 and the cable, thereby increasing the friction between the fixed cover 6 and the mesh sleeve body 2, reducing the probability of loosening, and completing the fixation of the cable through the above operation.

[0039] After completing the fixation of the cable, the staff will reinsert the limit frame 14 into the connecting column 1 and the sliding frame 13. At this time, the limit frame 14 has been inserted into the lower side of the sliding frame 13. The staff will then connect the towing rope 3 to the external traction device and use the external traction device to pull the cable to the required work position.

[0040] When it is no longer necessary to pull the cable, first disconnect the connection between the external traction device and the towing rope 3, then pull the limit frame 14 out of the connecting column 1 and the sliding frame 13 to release the limit of the sliding frame 13, and then the staff presses the sliding frame 13 downward. During the downward movement of the sliding frame 13, the two ropes 12 are no longer pulled. At this point, the swing plate 4 on the upper side loses the drag force, and under the action of the adjacent torsion springs of the fixed shell 7, the rotating shell 8 rotates in the opposite direction and pulls the lower parts of the two wire cores 11, so that the upper sides of the two wire cores 11 pull the adjacent swing plates 4 downward, and the swing plates 4 are reset and swung in the process of moving downward along the two fixed frames 9, and the remaining swing plates 4 not on the lower side are also reset while sliding and rotating along the two fixed frames 9. The swing plate 4 on the lower side is reset and rotated along the two fixed frames 9. Through the reset of all the above-mentioned swing plates 4, all the swing plates 4 no longer squeeze the net sleeve body 2, and the fixed cover 6 and all the connecting ropes 601 are gradually reset during the reverse rotation of the rotating shell 8, so that the fixed cover 6 no longer holds the cable tightly.

[0041] When the fixed cover 6 and all the connecting ropes 601 are no longer twisted, all the swing plates 4 and all the hinged plates 5 are restored. Figure 4 and Figure 5 In the state, the sliding frame 13 has moved to Figure 2 In the state, the staff immediately inserts the limit frame 14 into the rectangular hole on the upper side of the connecting column 1 and the sliding frame 13, and finally separates the device from the cable by the staff.

[0042] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
