Description

Technical Field

[0002] The laying of power grids is mainly used in the process of social construction. In order to ensure the stability, reliability and economy of power supply, the power of multiple power plants is connected through the power grid to form a national or regional transmission network, which can realize the optimal allocation and dispatch of power resources and ensure the quality and safety of power supply. At present, there are two commonly used methods for cable laying: direct burial and casing burial. The casing burial method uses pre-buried casing or cable trough to pull the cable in it to ensure the safety and wear resistance of the cable, which is suitable for long-distance laying. The direct burial method is to bury the cable directly underground. Although it saves time and effort, it is more prone to friction, damage and other problems, which are easy to affect the subsequent use of the cable.

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0029] like Figure 1-12As shown, the present invention provides a traction device for laying power grid lines, including a cable take-up wheel 2, a support 1 installed at the lower side of the cable take-up wheel 2 and a threader 6, and also including two receiving wheels 4 arranged correspondingly at the front and rear. The threader 6 is provided with two wires respectively wound on the surface of the receiving wheel 4 for receiving the threader 6. The surface of one end of the threader 6 away from the receiving wheel 4 is slidably matched with a fixing kit 7 capable of adjusting the position on the surface of the threader 6. The fixing kit 7 is used to fix the cable. After the fixing kit 7 is fixed on the surface of the threader 6 and fixes the cable, the fixing kit 7 is fixed on the surface of the threader 6. When the cable passes through the pipe, the cable can move with the threading device 6, so that the cable can be driven to pass through the pipe together when the threading device 6 passes through the pipe, thus forming a one-time pipe-threading effect; and the fixing kit 7 can move on the surface of the threading device 6. When the cable is too thick to be supported by pushing the threading device 6, the user can release the fixing kit 7 and the threading device 6 as needed, and then fix the fixing kit 791 to the threading device 6 after the threading device 6 passes through the casing, and then pull the threading device 6 to drive the cable to pass through the casing. The user can choose the fixing kit 791 according to the specific situation when using it. The cable pulling operation can be completed by the user through the cable pulling device 6. The left side of the storage wheel 4 is provided with a conveying device, and the threader 6 passes through the inner side of the conveying device. The threader 6 is conveyed by the conveying device, which can improve the conveying efficiency of the threader 6 and the cable threading efficiency. The upper and lower corresponding pressure wheels 8 are respectively arranged between the front and rear storage wheels 4. The cable can be transmitted between the upper and lower pressure wheels 8, and the cable is supported by the pressure wheel 8. The surface of the pressure wheel 8 is respectively provided with friction grooves with adjustable width. The friction groove is used to carry the cable and limit the cable. The width of the friction groove can be adjusted according to the diameter of the cable, so as to improve the limiting effect of the cable and improve the application range of the pressure wheel 8. The front end of the pressure wheel 8 is equipped with a control structure for controlling the upper pressure wheel 8 to move downward. When in use, the upper pressure wheel 8 is controlled by the control structure to move downward, and the cable is clamped with the lower pressure wheel 8, so as to further improve the limiting effect of the cable, and the transportation of the cable is not affected, which is conducive to the stable transportation of the cable and avoids the cable falling off and affecting the cable threading operation.

[0030] like Figure 2 and Figure 3 As shown, the fixing kit 7 includes four matching tubes 71 distributed in an annular shape, wherein two corresponding matching tubes 71 are coaxially fixedly connected to the tail end of the threader 6, and the other end is commonly fixedly connected to a guide rod for guiding when passing through the pipeline, and the other two corresponding matching tubes 71 are respectively fixedly connected to arc rods 78 at both ends, and the other ends of the arc rods 78 are respectively fixedly connected to the adjacent matching tubes 71, and the upper and lower sides of the inner side of the matching tubes 71 are respectively connected to clamping structures, and the clamping structures are used to clamp and fix the cable; The locking cam 77 is pressed against the locking cam 76 to lock the locking cam 76 in the locking cam 76. The locking cam 77 is pressed against the locking cam 76 to lock the locking cam 76. The locking cam 77 is pressed against the locking cam 76 to lock the locking cam 76. The second stop ring 73 is fixedly connected to the surface of the matching tube 71 on the upper side of the first stop ring 72, and the surface of the matching tube 71 between the first stop ring 72 and the second stop ring 73 is respectively sleeved with a push spring 74. When the cable passes through the clamping structure, the fixed block 77 will move outward under the force and drive the swing rod 75 to swing outward. When the swing rod 75 swings outward, it can push the first stop ring 72 to move outward and squeeze the push spring 74 under the push of the hinged rod 76, and push the fixed block 77 to press against the surface of the cable through the elastic force of the push spring 74, so as to control the fixed block 77 to clamp the cable in the initial state, improve the fixing effect of the fixed block 77 on the cable, and make the cable only move in one direction toward the clamping structure, so as to facilitate the pulling of the cable.

[0031] like Figure 4As shown, the upper and lower sides of the inner end of the fixed block 77 are respectively slidably connected with an inclined block 792 that can move outward, the outer ends of the inclined blocks 792 are respectively fixedly connected with support springs 794, the other ends of the support springs 794 are respectively fixedly connected to the fixed blocks 77, and the ends of the fixed blocks 77 corresponding to the inclined blocks 792 are respectively provided with connecting slide grooves, the ends of the inclined blocks 792 away from the cable are respectively fixedly connected with connecting sliders 793, the connecting sliders 793 are respectively slidably connected to the connecting slide grooves, the outer ends of the connecting sliders 793 are respectively fixedly connected with support springs 794, the other ends of the support springs 794 are respectively fixedly connected to the inner walls of the connecting slide grooves, and the support springs 794 are located at the connecting slide grooves. On the inner side of the slide groove, the corresponding ends of the upper and lower inclined blocks 792 are provided with an inclined structure inclined outward, and the support spring 794 is used to push the inclined surface of the inclined block 792 to fit the cable, and when the inclined block 792 is subjected to force, it will move outward under the action of the inclined surface and squeeze the support spring 794, thereby dispersing the inclined block 792 on the surface of the cable in the radial direction, and maintaining the clamping effect of the inclined block 792 and the cable under the push of the support spring 794, thereby ensuring the fixing effect of the cable while protecting the cable to avoid damage to the cable caused by the clamping force, and under the action of the inclined surface, it can be applicable to cables of different diameters, and has a wide range of applications.

[0032] Furthermore, in order to facilitate the fixing of the fixing kit 7 on the surface of the threader 6, the two ends of the matching tube 71 are respectively fixedly connected with a tapered threaded sleeve 79, and the corresponding two sides of the surface of the tapered threaded sleeve 79 are respectively provided with notches, and the surface of the tapered threaded sleeve 79 is respectively threadedly connected with a fixing sleeve 791. When the fixing sleeve 791 is rotated, the tapered threaded sleeve 79 can be squeezed by the threaded connection between the fixing sleeve 791 and the tapered threaded sleeve 79, so that the tapered threaded sleeve 79 presses the threader 6 inward, thereby fixing the fixing kit 7 on the surface of the threader 6. If the fixing kit 7 needs to be moved, it is only necessary to rotate the fixing sleeve 791 in the opposite direction to make the tapered threaded sleeve 79 elastically reset and no longer press the threader 6.

[0033] like Figure 5 and Figure 8 As shown, the left ends of the support 1 are respectively connected with the connecting plates 3 by bolts, the storage wheels 4 are respectively rotatably connected to the inner sides of the connecting plates 3, the left ends of the connecting plates 3 are respectively fixedly connected with the connecting frames 5, the pressing wheels 8 located at the lower side are respectively rotatably connected with the connecting frames 5, and the two ends of the pressing wheels 8 located at the upper side are respectively rotatably connected with the moving plates 21, and the lower ends of the moving plates 21 are respectively vertically slidably connected with the surfaces of the connecting frames 5; The control structure includes a swing plate 25, the upper end of the swing plate 25 is hinged with a pull rod 24, the other end of the pull rod 24 is hinged with the upper end of the movable plate 21, the lower end of the swing plate 25 is rotatably connected to the connecting frame 5, and the lower end of the swing plate 25 is coaxially fixedly connected with a first worm gear 26, one side of the first worm gear 26 is meshed with a first worm 27, the first worm 27 is rotatably connected to the connecting frame 5, and the upper end of the first worm 27 is fixedly connected with a control knob 28, which is used to control the pressure wheels 8 on the upper and lower sides. The user can adjust the spacing according to the diameter of the cable. When the control knob 28 is rotated, the first worm 27 can be driven to rotate. When the first worm 27 rotates, the swing plate 25 can be driven to rotate through the engagement with the first worm wheel 26. When the swing plate 25 rotates, the pressure wheel 8 on the upper side can be driven to move downward through the linkage of the pull rod 24. The cable is clamped and supported by cooperating with the pressure wheel 8 on the lower side, and the worm gear transmission has a self-locking effect, which can support the pressure wheel 8 on the upper side.

[0034] like Figure 5-Figure 7 As shown, in order to facilitate the pulling of cables, the surface of the movable plate 21 is rotatably connected with a spline sleeve 18, and the inner side of the spline sleeve 18 is spline-connected with a spline shaft 17. When the spline shaft 17 rotates, the spline sleeve 18 can be driven to rotate, and the spline sleeve 18 can move axially on the surface of the spline shaft 17. The lower ends of the spline shaft 17 are rotatably connected with the connecting frame 5, and the lower side surfaces of the spline sleeve 18 and the spline shaft 17 are coaxially fixedly connected with a first reversing bevel gear 19, and the two ends of the pressure wheel 8 are coaxially fixedly connected with a second reversing bevel gear 20, and the outer ends of the second reversing bevel gear 20 are respectively meshed with the corresponding first reversing bevel gear 19. The lower end of the spline shaft 17 on the front side is provided with a motor 16, and the output end of the motor 16 is connected to the spline shaft on the upper side. The bottom of 17 is coaxially fixedly connected, and an arc-shaped pad is coaxially provided on the lower side of the pressure wheel 8, which is fixedly connected to the connecting frame 5 for protecting the pressure wheel 8. The motor 16 is fixedly connected to the arc-shaped pad. When the motor 16 rotates, the spline shaft 17 can rotate, thereby driving the spline sleeve 18 to rotate. When the spline shaft 17 rotates, the lower pressure wheel 8 can be driven to rotate through the engagement of the first reversing bevel gear 19 and the second reversing bevel gear 20. When the spline sleeve 18 rotates, the upper pressure wheel 8 can be driven to rotate through the engagement of the first reversing bevel gear 19 and the second reversing bevel gear 20, so that the pressure wheels 8 on both sides can rotate synchronously relative to each other, driving the middle cable to be transported without affecting the downward movement of the upper pressure wheel 8, which is convenient for users to operate.

[0035] Furthermore, if Fig.10 and Fig.11As shown, in order to facilitate the threader 6 to pull the cable, the conveying equipment includes upper and lower corresponding conveying belt wheel components, the conveying belt wheel components include two left and right corresponding conveying belt wheels 29 and a conveying belt 30 sleeved on the surfaces of the two conveying belt wheels 29, the two threaders 6 are respectively located between the two corresponding conveying belts 30, each threader 6 is respectively pressed by the upper and lower corresponding threaders 6, the front ends of the left and right conveying belt wheels 29 are rotatably connected with an auxiliary plate 31, the lower auxiliary plate 31 is fixedly connected to the connecting frame 5, and the upper auxiliary plate 31 is respectively connected with a swinging component that can swing synchronously, and the spacing between the upper and lower conveying belt wheel components is adjusted by the swinging component; The two ends of the pressure wheel 8 located at the lower side are respectively coaxially fixedly connected with the second linkage pulley 33, and the conveying pulley 29 located on the left side of the upper end is respectively coaxially fixedly connected with the first linkage pulley 32, and a transmission belt is respectively sleeved between the adjacent first linkage pulley 32 and the second linkage pulley 33. The first linkage pulley 32, the second linkage pulley 33 and the transmission belt are used to keep the pressure wheel 8 and the conveying pulley 29 in synchronous transmission. When the pressure wheel 8 rotates, the conveying pulley 29 is driven to rotate by the first linkage pulley 32, the second linkage pulley 33 and the transmission belt, and the left and right sides are relatively rotated under the linkage of the conveyor belt 30. The corresponding conveyor pulley 29 rotates synchronously, and then under the action of the friction force between the upper and lower conveyor belts 30, it rotates synchronously to convey the threader 6. When the threader 6 moves, the cable moves synchronously. The threader 6 provides toughness for the cable, which is beneficial for the cable to pass through the pipeline, thereby improving the efficiency of the cable passing through the pipeline. The swinging component can drive the conveyor pulley component on the upper side to move up and down, which not only makes it convenient to place the threader 6 between the conveyor pulley components for use, but also can increase the clamping force of the conveyor belt 30 and the threader 6, thereby further improving the conveying effect of the threader 6.

[0036] like Fig.11As shown, the swing component includes a first parallel rod 34 and a second parallel rod 35 arranged parallel to each other, the upper end of the first parallel rod 34 is rotatably connected with the first linkage pulley 32 on the front side, and the lower end is rotatably connected with the front end of the pressing wheel 8 on the lower side, the upper end of the second parallel rod 35 is hinged with the upper auxiliary plate 31, and the lower end of the second parallel rod 35 is rotatably connected with the connecting frame 5, so that when the first parallel plate and the second parallel plate swing synchronously, the upper auxiliary plate 31 can be driven to move up and down, thereby driving the upper conveying belt wheel component to move up and down, and because the spacing between the first linkage pulley 32 and the second linkage pulley 33 remains unchanged when the first parallel plate swings, the first linkage pulley 32 and the second linkage pulley 33 can still be transmitted when the first parallel plate and the second parallel plate swing, without affecting the transmission effect of the conveying belt wheel 29, and a linkage shaft is fixedly connected between the front and rear corresponding second parallel rods 35, and the front end of the linkage shaft is coaxial. A second worm gear 37 is fixedly connected, and a second worm 36 is meshed on the upper side of the second worm gear 37. The second worm 36 is rotatably connected to the connecting frame 5. A control handle 38 is fixedly connected to the right end of the second worm gear 36. The control handle 38 is used to control the swing of the second parallel plates on the front and rear sides, and under the linkage action of the auxiliary plate 31, the first parallel rods 34 and the second parallel rods 35 on the front and rear sides can swing synchronously, so that the two conveyor belt wheel components on the upper side can move up and down synchronously; when the control handle 38 is rotated, the second worm gear 36 can be driven to rotate, and when the second worm gear 36 rotates, the second parallel rods 35 can be driven to swing through the meshing of the second worm gear 36 and the second worm gear 37, and then the conveyor belt wheel component on the upper side is controlled to adjust the height under the linkage of the auxiliary plate 31, and the worm gear transmission has a self-locking effect, which can not only ensure the squeezing effect of the upper conveyor belt 30 on the threader 6, but also ensure the stability of the conveyor belt wheel component when it is working.

[0037] like Figure 7As shown, in order to facilitate the adjustment of the width of the friction groove according to the diameter of different cables, two adjustment plates 9 are axially slidably connected to the inner side of the friction groove on the surface of each pressure wheel 8, and the surfaces of the corresponding ends of the two adjustment plates 9 are respectively provided with clamping surfaces 39 inclined outward, and the clamping surfaces 39 are used for the inclined surfaces inside to fit the cables, which can be suitable for cables of different diameters; a mounting hole is provided from one end of the pressure wheel 8 to the other end, and a double-threaded screw 10 is rotatably connected to the inner side of the mounting hole, and the surface of the double-threaded screw 10 is provided with two sections of threads with opposite rotation directions, and the surface of the double-threaded screw 10 is respectively threadedly connected with two connecting rings 40, and the connecting rings 40 are respectively It is threadedly connected to one section of the thread, and strip grooves are respectively provided on both sides corresponding to the surface of the friction groove. The connecting ring 40 is fixedly connected to the corresponding adjustment plate 9 through the strip grooves. When in use, the pressure wheel 8 can be fixed to drive the double-threaded screw 10 to rotate. When the double-threaded screw 10 rotates, the two adjustment plates 9 can be driven to move outward synchronously under the action of the threaded connection between the threads at both ends of the surface and the connecting ring 40, thereby increasing the distance between the adjustment plates 9, thereby increasing the width of the cable that the friction groove can accommodate. When the double-threaded screw 10 is reversed, the distance between the adjustment plates 9 can be reduced, and it can be adjusted according to actual conditions during use.

[0038] Furthermore, in order to facilitate the user to control the spacing of the adjustment plate 9 and improve the convenience of the user's operation, as Figure 6 As shown, the rear ends of the double-threaded screw 10 are respectively fixedly connected with a conical wheel 11, and the surfaces of the conical wheels 11 are respectively provided with braking protrusions. The rear sides of the conical wheels 11 are respectively provided with limited sleeves 12 coaxially, and the inner sides of the limited sleeves 12 are respectively provided with grooves meshing with the braking protrusions, and the grooves are in a conical structure meshing with the conical wheels 11, thereby improving the braking effect on the conical wheels 11. The rear ends of the upper and lower limited sleeves 12 are fixedly connected with a linkage plate 13, and the front end of the linkage plate 13 is provided with a mounting bracket 14, which is installed The mounting frame 14 is fixedly connected to the connecting frame 5, and the upper and lower sides of the mounting frame 14 are respectively fixedly connected with mounting rods 41, and the linkage plates 13 are respectively slidably connected with the mounting rods 41.

The right end of the linkage plate 13 is fixedly connected with a handle, which is used to facilitate pushing the linkage plate 13. During use, when the pressure wheel 8 rotates, the double-threaded screw 10 can rotate synchronously with the pressure wheel 8 under the linkage of the connecting ring 40. If it is necessary to control the adjustment plate 9 to move outward, the linkage plate 13 can be pressed forward when the pressure wheel 8 rotates. The linkage plate 13 drives the limit sleeve 12 to move forward to engage with the conical wheel 11. Since the limit sleeve 12 is fixed, when the limit sleeve 12 is engaged with the conical wheel 11, the double-threaded screw 10 can be rotated through the engagement of the card slot and the braking protrusion. When the double-threaded screw 10 is fixed, the pressure wheel 8 is still in a rotating state, so it can drive the connecting ring 40 on the surface of the double-threaded screw 10 The cam 12 is a very convenient and economical way to operate the cable, and the cam 12 is very convenient for users to operate. ...
