Description

Technical Field

[0001] This invention relates to the field of auxiliary devices for conductor construction, specifically a conductor laying pulley balance suspension device. Background Technology

[0002] In the construction of power equipment, cable laying pulleys are often used to transport cables. The cable laying pulley balance suspension device uses suspension wheels to transport cables to the installation position at high altitudes, providing support and laying channels for the conductors. It plays a very important role in completing conductor erection, protecting conductors, and improving the efficiency of cable laying construction.

[0003] The existing balance suspension device works by having the conductor roll along the top outer wall of the suspension wheel during the conductor laying process. Before the conductor rolls, the conductor's connecting pipe protection device needs to be laid through the suspension wheel. When the connecting pipe protection device is laid through the suspension wheel, the conductor needs to be laid out slowly so that the connecting protection device can pass smoothly over the suspension vehicle.

[0004] Existing balanced suspension devices face the following challenges during the wire laying process:

[0005] 1. Due to the weight of the conductor and the influence of external environmental factors, the envelope angle of the conductor passing through the suspension wheel increases, which can easily cause the port of the connecting pipe protection device to be subjected to a violent impact on the suspension wheel. In severe cases, this can easily lead to damage to the conductor and the connecting protection device.

[0006] 2. Due to the construction environment, there are hard substances on the surface of the conductor. When the conductor is laid out, the hard substances on the surface of the conductor can easily adhere to the surface of the pulley. When the pulley rotates, the hard substances on its surface and the conductor laying process can easily cause many scratches on the pulley, thereby reducing the service life of the pulley and making the appearance of the suspension wheel unsightly. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By applying the technical solution of this invention, and addressing the problems encountered in the existing technology during conductor laying, this invention alleviates the impact force on the connection protection device through a shock-absorbing component. Under the dragging pressure of the conductor, the shock-absorbing seat rotates at a certain angle. During the rotation of the shock-absorbing seat, the lifting plate pushes the push rod and push plate upward under the restraining pressure of the fixed plate, which in turn pushes the limit rod upward, thereby driving the connection protection device upward. This reduces the envelope angle of the connection protection device on the conductor pulley. At the same time, under the rotational pressure of the connecting shaft rod, the protective component rotates in advance between the conductor pulley and the connection protection device. At this time, the fixed arc seat inside the arc-shaped component protects the conductor pulley, reducing the impact force of the external force on the conductor pulley. Moreover, the ball bearings roll with the conductor pulley without affecting the normal rolling of the conductor pulley, thereby improving the working efficiency of the conductor pulley and greatly enhancing the safety of the conductor pulley and the connection protection device.

[0023] 2. By applying the technical solution of this invention, and addressing the problems encountered in the existing technology during wire laying, this invention utilizes the kinetic energy of the wire pulley to transfer to the connecting shaft through a cleaning component. Then, through the cooperation of the driving roller, the driven roller, and the conveyor belt, the driven rod is driven to rotate. The wire pulley rotates in the same direction, and the brush also rotates in the same direction, so that the brush can clean hard substances and dust along the wire pulley, preventing hard substances from scratching the wire pulley and preventing dust from accumulating on the surface of the wire pulley, thereby improving the cleaning effect and enhancing the aesthetics of the wire pulley.

[0024] 3. By applying the technical solution of the present invention, the present invention addresses the problems encountered in the wire laying process in the prior art. The present invention utilizes the kinetic energy of the connecting shaft rod through the flipping component, causing the pusher plate to push the wire and the connecting protection device to overturn together. This reduces the envelope angle of the wire passing through the pulley, thereby further reducing the impact of the connecting protection device on the pulley and improving the pass rate of the connecting protection device. The present invention also incorporates a reset disc spring, which helps to maintain a certain tension in the steel rope.

[0025] 4. By applying the technical solution of the present invention, and addressing the problems encountered in cleaning insulators in the prior art, the present invention achieves the clamping of the first and second seats on the suspension frame by using a threaded connection between the torsion rod and the first seat through a quick installation component. Specifically, the limiting movement of the movable seat causes the limiting inclined rod to slide along the upper limit of the limiting inclined groove, thereby pressing the wedge block on the wedge block groove, so as to quickly improve the installation efficiency or disassembly efficiency.

[0026] 5. By applying the technical solution of the present invention, the present invention addresses the problems encountered in the wire laying process in the prior art. The present invention uses the elastic force of the second reset spring to push along the surface of the wire pulley with the arc-shaped push plate, thereby cleaning the hard material on the wire pulley again and preventing the hard material on the wire pulley from contacting the wire again, which helps to maintain the smoothness of the wire pulley.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figures 1 to 10 The present invention provides a technical solution:

[0047] Example 1: As Figure 1 , Figure 2 and Figure 5As shown, a conductor laying pulley balancing suspension device includes a suspension frame 1. Three coaxial conductor pulleys 2 are rotatably connected to the inner side of the suspension frame 1. Multiple protective components 3 are provided at the bottom front end of the suspension frame 1 to prevent impact from the connecting pipe protection device. The protective components 3 include a connecting seat 31 at the bottom front end of the suspension frame 1. An arc-shaped part 32 is rotatably provided on one side of each set of conductor pulleys 2 corresponding to the connecting seat 31. The arc-shaped part 32 is adapted to the outer side wall of the conductor pulley 2. A connecting shaft rod 30 is rotatably connected to the middle of the connecting seat 31. One end of the arc-shaped part 32 near the connecting seat 31 is fixed to the outer side of the connecting shaft rod 30. A fixed arc seat 33 is installed on the side of the arc-shaped part 32 near the conductor pulley 2. An anti-slip pad is installed between the fixed arc seat 33 and the arc-shaped part 32. Ball bearings 34 are installed in a linear array on the side of the fixed arc seat 33 near the conductor pulley 2. A support pulley 35 is installed at the free end of the arc-shaped part 32.

[0048] During operation, when the connecting pipe protection device approaches the conductor pulley 2 under the drag of the traction line, the connecting pipe protection device pushes the arc-shaped part 32 to abut against the outer wall of the conductor pulley 2. Thus, each set of arc-shaped parts 32 will provide protection on the side wall of the conductor pulley 2. When the arc-shaped part 32 impacts the side wall of the conductor pulley 2, the fixed arc seat 33 will play a shock-absorbing role for the connecting pipe protection device. Moreover, when the fixed arc seat 33 abuts against the arc-shaped part 32, the connected ball bearing 34 and the conductor pulley 2 are in a rolling state, which helps to ensure the normal rolling of the conductor pulley 2.

[0049] It is worth noting that the anti-slip pad provided in this invention helps to improve the stability of the fixed arc seat 33 inside the arc member 32 and prevents the fixed arc seat 33 from shaking. The support pulley 35 provided in this invention helps to support the wire after the arc member 32 returns to its original position, preventing the envelope angle of the wire on the wire pulley 2 from becoming excessively large.

[0050] Example 2:

[0051] It includes all the contents of the technical solution in Embodiment 1, the difference being that... Figure 1 , Figure 4 and Figure 5As shown, a shock-absorbing component 4 for damping the connecting pipe protection device is provided at the bottom front end of the suspension frame 1 and between adjacent protective components 3. The shock-absorbing component 4 includes a shock-absorbing seat 41 rotatably connected to one side of the connecting seat 31 and disposed between adjacent arc-shaped parts 32. One end of the shock-absorbing seat 41 is fixedly connected to the outer side of the connecting shaft rod 30. A shock-absorbing rod 42 is slidably connected to the end of the shock-absorbing seat 41 away from the connecting seat 31. A limit groove 43 is provided above the shock-absorbing seat 41, and a limit rod fixedly connected to one end of the shock-absorbing rod 42 is slidably provided in the limit groove 43. The outer side of the damping rod 42 is fitted with a damping spring 45. The end of the damping rod 42 facing away from the damping seat 41 is fitted with a semi-arc seat 46. Each set of damping seats 41 is fitted with a limiting seat 411 above it. The inner side of the limiting seat 411 is slidably connected with a push rod 412. The upper inclined end of the push rod 412 is fitted with a push plate 413. The outer side of the lower inclined end of the push rod 412 is fitted with a first reset spring 414. The lower inclined end of the push rod 412 is fitted with a lifting plate 415. A fixing plate 416 is installed at the bottom of the suspension frame 1 and between adjacent guide pulleys 2.

[0052] During operation, as the connecting pipe protection device approaches the suspension frame 1, it comes into contact with the semi-arc seat 46. When the semi-arc seat 46 is under external pressure, it transmits power from the shock absorber rod 42. At this time, the limit rod 44 slides down along the limit groove 43 to the lower limit and approaches the push plate 413. The shock absorber spring 45 releases its elastic potential energy to buffer and dampen the shock, thereby fully relieving the power and achieving the shock absorption effect. Moreover, the semi-arc seats 46 on both sides will rotate a certain angle under the pressure of the connecting protection device. At this time, the shock absorber seat 41 drives the connecting shaft rod 30 to rotate together. The connecting shaft rod 30 will drive the arc-shaped part 32 to rotate and fit in advance. The shock absorber 41 rotates, and the lifting plate 415 connected to it moves upward along the limit seat 411 under the restraint of the fixed plate 416. The first return spring 414 is compressed and generates a reverse elastic force. At this time, the push plate 413 pushes the limit rod 44 to move upward, which in turn causes the semi-arc seat 46 to push the connection protection device upward, reducing the envelope angle of the connection protection device passing through the pulley. This helps the connection protection device to pass smoothly through the wire pulley 2, preventing the connection protection device from being impacted after passing through the wire pulley 2 and causing damage to the wire and the connection protection device.

[0053] The elastic force of the first reset spring 414 pushes the protective component 3 and the shock-absorbing component 4 to reset.

[0054] Example 3:

[0055] It includes all the contents of Example 2, the difference being that... Figure 1 , Figure 2 , Figure 4 and Figure 7As shown, the suspension frame 1 has quick-installation components 5 on both the left and right sides for quick installation of the protective component 3 and the shock-absorbing component 4. Each quick-installation component 5 includes a first seat 51 and a second seat 52. The first seat 51 is located on the right side of the guide pulley 2, and the second seat 52 is located on the left side of the guide pulley 2. The first seat 51 has a hollow structure. A torsion rod 53 is threaded onto the rear end of the first seat 51. One end of the torsion rod 53 rotatably passes through the outside of the first seat 51 and is fitted with a nut. The other end of the torsion rod 53 extends into the inside of the first seat 51 and is rotatably connected to a movable seat 54. The movable seat 54 and the inner cavity bottom wall of the first seat 51 are connected by a slide rail. The movable seat 54 and the first seat... Compression springs 55 are connected between the inner cavity sidewalls of 51. The top of the movable seat 54 is provided with a linear array of limiting grooves 56. A limiting rod 58 is slidably provided on the inner side of each set of limiting grooves 56. A movable plate 57 is installed on the top of several limiting rods 58. A pressing rod 59 is installed on the left end of the movable plate 57 in a linear array. One end of each set of pressing rods 59 slides through the outer side of the first seat 51 and a wedge 510 is installed. A wedge 510 is fixedly installed on the side of the second seat 52 near the first seat 51, or the second seat 52 and its components are symmetrically arranged with the same structure as the first seat 51. A wedge groove 511 is provided at the bottom of the left and right ends of the guide pulley 2 and on the side corresponding to the wedge 510.

[0056] During operation, the first seat 51 and the second seat 52 are aligned on the wedge groove 511. Then, the nut and the torsion rod 53 are turned to rotate, causing the moving seat 54 to move along the upper limit of the first seat 51. At this time, the compression spring 55 enters the compression state, and the limiting inclined rod 58 slides along the limiting inclined groove 56, thereby causing the pressing rod 59 to push the wedge 510 into the wedge groove 511. When disassembling, it is only necessary to turn the nut in the opposite direction, which is conducive to the quick installation and disassembly of the protective component 3 and the shock absorption component 4.

[0057] It is worth noting that the wedge 510 and wedge groove 511 provided in this invention are beneficial to increasing the friction between the suspension frame 1 and the quick-installation assembly 5, and are not beneficial to causing the suspension frame 1 and the quick-installation assembly 5 to shift.

[0058] like Figure 4 , 8 As shown, the wedge groove 511 has an opening at one end to facilitate the quick removal of the wedge 510, and the force applied by the connecting pipe protection device / cable to the quick installation assembly 5 is opposite to the force applied by the wedge groove 511 to the wedge 510.

[0059] Example 4:

[0060] It includes all the content of Example 3, the difference being that... Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the front end of the quick-installation assembly 5 is provided with a flipping assembly 6 for flipping the wire upwards. The flipping assembly 6 includes ear seats 61 installed at the front ends of the first base 51 and the second base 52. A through-rotating rod 60 is rotatably connected through the middle of the two ear seats 61. An auxiliary plate 62, which is fixedly connected to the through-rotating rod 60, is rotatably connected to the inner side of the two ear seats 61. A push-wire plate 63 is installed between the ends of the two auxiliary plates 62 away from the ear seats 61. A first drive block 64 is installed on the opposite side of the two through-rotating rods 60. The first base 51 and the second base 52... A fixed wheel 65 is rotatably connected to the opposite side. The left and right ends of the connecting seat 31 are rotatably connected to a second drive block 66 that is fixedly connected to the connecting shaft rod 30. The top of the first drive block 64 and the front end of the second drive block 66 are connected to a steel rope that passes through the bottom of the fixed wheel 65. A coil spring cavity cover 67 is installed on the opposite side of the through-rotor rod 60. The coil spring cavity cover 67 is a hollow structure. One end of the through-rotor rod 60 that extends into the coil spring cavity cover 67 away from the ear seat 61 is connected to a reset coil spring 68. The other end of the reset coil spring 68 is connected to the side wall of the coil spring cavity cover 67.

[0061] During operation, as the connecting shaft 30 rotates, it drives the second drive block 66 connected to it to rotate. At this time, the steel rope drives the first drive block 64 to rotate during the rotation of the second drive block 66. The first drive block 64 then drives the through-rotor 60 to rotate synchronously. Subsequently, the auxiliary plate 62 drives the pusher plate 63 to rotate synchronously. This helps the pusher plate 63 push the wire and the connecting protection device to overturn together, thus reducing the envelope angle of the wire passing through the pulley and further reducing the impact of the connecting protection device on the pulley. After the pusher plate 63 rotates, the reset coil spring 68 inside the coil spring cavity cover 67 generates a reverse elastic force, which tends to drive the through-rotor 60 to rotate back in the opposite direction to reset. This helps to maintain a certain tension in the steel rope and prevents the steel rope from detaching from the fixed wheel 65 during the rotation of the pusher plate 63.

[0062] Example 5:

[0063] It includes all the content of Example 4, the difference being that, as Figure 8 , Figure 9 and Figure 10As shown, a cleaning assembly 7 for cleaning the outer surface of the guide pulley 2 is provided at the rear end of the suspension frame 1. The cleaning assembly 7 includes a passive rod 75 located at the rear end of the suspension frame 1. A brush cylinder 76 is provided on the outer side of the passive rod 75 and on one side of each group of guide pulleys 2. Adjusting components 77 are installed at the left and right ends of the brush cylinder 76. A ring array of brushes 78 is installed on the outer wall of the brush cylinder 76. The ring array of brushes 78 is adapted to the shape of the guide pulley 2. The brushes 78 are hard brushes and are close to the inner side of the guide pulley 2. A drive roller 71 is provided at the right end of the suspension frame 1. The connecting shaft in the middle of the drive roller 71 rotates through the inner side of the suspension frame 1 and is fixedly connected to the guide pulley 2. Fixing brackets 72 are installed on the side walls of the left and right ends of the suspension frame 1. A passive roller 73 is rotatably connected to the end of the fixed frame 72 away from the suspension frame 1. The drive roller 71 and the passive roller 73 are connected by a transmission belt 74. The left and right ends of the passive rod 75 rotate through the fixed frame 72 and are coaxially fixedly connected to the passive roller 73. A rotating rod 711 is rotatably connected to the bottom of the suspension frame 1. A support frame 712 is installed at the bottom of each set of guide pulleys 2 corresponding to the top of the rotating rod 711. A second return spring 713 is connected between the support frame 712 and the bottom wall of the suspension frame 1. An arc-shaped push plate 714 is installed at the end of the support frame 712 away from the rotating rod 711. The arc-shaped push plate 714 is tightly attached to the side wall of the guide pulley 2 under the elastic force of the second return spring 713. Side plates 715 are installed at the left and right ends of the arc-shaped push plate 714.

[0064] During operation, as the guide pulley 2 rotates, the drive connecting shaft drives the drive roller 71 to rotate. Through the transmission action of the conveyor belt 74, the driven roller 73 and the driven rod 75 rotate. Specifically, the guide pulley 2 rotates in the same direction, and then the driven rod 75, through the cooperation of the drive roller 71, the driven roller 73, and the conveyor belt 74, also causes the brush 78 to rotate in the same direction. This allows the brush 78 to clean hard materials and dust along the guide pulley 2, preventing hard materials from scratching the guide pulley 2 and preventing dust from accumulating on the surface of the guide pulley 2, thereby improving the cleaning effect and enhancing the appearance of the guide pulley 2.

[0065] When the brush 78 is unable to clean the hard material stuck in the wire pulley 2, as the wire pulley 2 rotates onto the arc-shaped push plate 714, the arc-shaped push plate 714 and the side plate 715 use the elastic force of the second return spring 713 to push along the surface of the wire pulley 2, thereby cleaning the hard material on the wire pulley 2 again, preventing the hard material on the wire pulley 2 from contacting the wire again, which helps to maintain the smoothness of the wire pulley 2.

[0066] It is worth noting that the adjusting member 77 provided in this invention facilitates the worker to drive the brush cylinder 76 to slide along the axis of the passive rod 75, so that each set of brushes 78 is aligned with the guide pulley 2, thereby improving the cleaning effect.

[0067] Working principle: This is used for the balancing suspension device of the conductor laying pulley. When in use:

[0068] First, as the connecting pipe protection device approaches the suspension frame 1, it will come into contact with the semi-arc seat 46. When the semi-arc seat 46 is under external pressure, it transmits power from the shock absorber rod 42. At this time, the limit rod 44 slides down along the limit groove 43 to the lower limit and approaches the push plate 413. The shock absorber spring 45 releases elastic potential energy, thereby fully relieving the power and playing a shock absorption role. Moreover, the semi-arc seats 46 on both sides will rotate a certain angle under the pressure of the connecting protection device. At this time, the shock absorber 41 drives the connecting shaft rod 30 to rotate together. The connecting shaft rod 30 will drive the arc-shaped part 32 to rotate and fit against the wire pulley 2 in advance, thereby playing a protective role for the wire pulley 2. When the shock absorber 41 rotates, the lifting plate 415 connected to it will move upward along the limit seat 411 under the restraint of the fixed plate 416. At this time, the push plate 413 will push the limit rod 44 to move upward, thereby causing the semi-arc seat 46 to push the connecting protection device upward, reducing the envelope angle of the connecting protection device passing through the pulley.

[0069] Secondly, when the connecting pipe protection device approaches the conductor pulley 2 under the drag of the traction line, the connecting shaft rod 30 will drive the arc-shaped part 32 to rotate in advance, and then the fixed arc seat 33 will contact the conductor pulley 2, which will then play a shock-absorbing role for the connecting pipe protection device. Moreover, when the fixed arc seat 33 is in contact with the arc-shaped part 32, the connected ball 34 and the conductor pulley 2 are in a rolling state, which helps to ensure the normal rolling of the conductor pulley 2.

[0070] Third, when the connecting shaft rod 30 rotates, it drives the second drive block 66 connected to it to rotate. At this time, the steel rope drives the first drive block 64 to rotate during the rotation of the second drive block 66. The first drive block 64 drives the through-rotor rod 60 to rotate synchronously. Subsequently, the auxiliary plate 62 drives the pusher plate 63 to flip synchronously. This helps the pusher plate 63 push the wire and the connecting protection device to overturn together, thus reducing the envelope angle of the wire passing through the pulley and further reducing the impact of the connecting protection device on the pulley. After the pusher plate 63 flips, the reset coil spring 68 inside the coil spring cavity cover 67 releases elastic potential energy, driving the through-rotor rod 60 to rotate quickly in the opposite direction. At this time, the through-rotor rod 60 drives the first drive block 64 and the steel rope to return to their original positions, which helps to maintain a certain tension in the steel rope.

[0071] Fourth, during the rotation of the guide pulley 2, the drive connecting shaft drives the drive roller 71 to rotate. Under the transmission action of the conveyor belt 74, the driven roller 73 and the driven rod 75 rotate. Specifically, the guide pulley 2 rotates in the same direction, and the driven rod 75, through the cooperation of the drive roller 71, the driven roller 73, and the conveyor belt 74, also causes the brush 78 to rotate in the same direction. This allows the brush 78 to clean hard materials and dust along the guide pulley 2, preventing hard materials from scratching the guide pulley 2. When the brush 78 cannot clean the hard materials that are deeply embedded in the guide pulley 2, as the guide pulley 2 rotates to the arc-shaped push plate 714, the arc-shaped push plate 714 and the side plate 715 use the elastic force of the second return spring 713 to push along the surface of the guide pulley 2, thereby cleaning the hard materials on the guide pulley 2 again.
