Description

Technical Field

[0001] This invention belongs to the technical field of cable installation equipment, specifically relating to a load-bearing overhead cable installation device and its usage method. Background Technology

[0002] In the construction and operation and maintenance of overhead transmission and distribution lines, the laying and installation of load-bearing overhead cables is one of the core construction links. Currently, the industry generally adopts the line-laying process of pulleys and traction plates. Pulleys are laid sequentially on the towers along the line route. The cable to be laid is supported in the guide groove of the pulley. The traction plate at the front end is pulled by the traction equipment, which drives the cable to slide continuously along each pulley, and finally completes the laying and installation of the entire cable.

[0003] During actual construction, when the traction plate crosses the pulley, it is highly susceptible to axial rollover due to the combined effects of factors such as changes in the traction angle, uneven load on the cable's own weight, and poor transition of the wheel structure. It can even detach and become stuck directly from the pulley groove, causing traction interruption, abrasion damage to the cable's outer sheath, and in severe cases, even traction rope breakage or components falling from heights. During the continuous traction phase of the cable, changes in line turning angle tension, wind load disturbances, and fluctuations in traction speed can cause the cable to sway laterally within the guide wheel groove, posing a risk of detaching from the groove. To prevent such problems, workers must constantly monitor the cable's condition within the guide wheel groove during the operation, making it impossible to achieve unmanned or minimally manned continuous traction operations. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a load-bearing overhead cable installation device and method of use, which can effectively prevent the traction plate from flipping and falling out of the groove and the cable from jumping out of the groove and getting stuck, thereby improving the efficiency and safety of overhead line construction.

[0005] The objective of this invention is achieved as follows: A load-bearing overhead cable installation device includes a base plate, on which a guide wheel frame is mounted. The guide wheel frame is equipped with a guide wheel and a guide wheel adjustment assembly, which adjusts the height of the guide wheel. Limit frames are provided on both the front and rear sides of the guide wheel, connected to the support axle of the guide wheel, allowing them to maintain the same position as the guide wheel, i.e., rise or fall together. Multiple limit rollers are mounted on the limit frames, with the highest point of each roller higher than the bottom of the guide wheel groove and lower than the guide wheel's edge. The lateral position of each limit roller can be adjusted to control the spacing between cables. Lifting frames are connected to the front and rear sides of the base plate, each lifting frame equipped with lifting rollers and a lifting drive assembly, which adjusts the height of the lifting rollers.

[0006] During overhead line traction operations, when the traction plate needs to pass the guide wheel, the height of the lifting roller and the guide wheel can be adjusted by the lifting drive assembly and the guide wheel adjustment assembly, respectively. This adjusts the angle and height of the traction rope or cable entering and exiting the device, preventing the traction plate from flipping or becoming stuck due to the height between it and the guide wheel, the angle of traction force, etc. During cable traction, each limit roller can cooperate with the groove of the guide wheel to further control the spacing of the cable, preventing it from twisting or derailing due to the influence of traction torque, angular tension, wind load disturbance, etc.

[0007] Furthermore, the guide wheel adjustment assembly includes a guide wheel adjustment motor connected to a guide wheel adjustment screw. The guide wheel adjustment screw is threadedly connected to a second connecting block, which is connected to a second sliding block. The second sliding block is slidably connected to the guide wheel frame. A sleeve plate is provided at the end of the support wheel shaft of the guide wheel, and the limiting frame is connected to the sleeve plate. The height of both the guide wheel and the limiting frame can be adjusted simultaneously using the guide wheel adjustment motor.

[0008] Furthermore, the limiting frame includes a connecting frame connected to the socket plate, the connecting frame is connected to a second support plate, the second support plate is provided with a plurality of adjusting slides, and the limiting roller is disposed on the adjusting slides. The spacing of the limiting roller and its spacing with the edge of the guide wheel groove can be adjusted by adjusting the position of each adjusting slide to adapt to different cable spacings.

[0009] Furthermore, the lifting frame includes a first support plate connected to the base plate, a first upright plate is provided on the first support plate, and a first slide block is slidably connected to the first upright plate. The lifting roller is rotatably connected between two of the first slide blocks. The lifting drive assembly includes a lifting motor, a lifting screw connected to the lifting motor, and a first connecting block threadedly connected to the lifting screw. The first connecting block is connected to the first slide block. The height of the lifting roller can be automatically adjusted and controlled by the operation of the lifting motor.

[0010] Furthermore, a lateral adjustment mechanism is provided on the base plate for adjusting the lateral position of the guide wheel frame. The lateral adjustment mechanism includes a guide frame plate and a lateral movement motor. A lateral movement seat plate is slidably disposed between the guide frame plates, and the guide wheel frame is mounted on the lateral movement seat plate. The lateral movement motor is connected to a lateral movement screw, which is threadedly connected to the guide wheel frame. During operation, the lateral movement motor can be activated as needed to adjust the lateral position of the guide wheel frame, meeting the requirements of complex operating environments.

[0011] Furthermore, a fixed bracket is provided at the bottom of the base plate. The fixed bracket includes a bracket plate and a long screw rod, which can connect the bracket plate to the crossbeam to ensure the stable installation of the device.

[0012] A method of using a load-bearing overhead cable installation device includes the following steps:

[0013] S1. Fix this device on the crossarms of the two towers where the cable is to be laid;

[0014] S2. Pass the traction rope connected to the traction plate through the middle of this device, so that the traction rope is above the guide wheel and lifting roller of this device; when pulling and releasing the line, the traction rope and the cable connected to the traction plate are both supported and guided by the guide wheel on this device.

[0015] S3. When the traction plate is to pass through this device, the lifting roller is first raised by the lifting drive assembly so that it is supported under the traction rope or cable. Then, the guide wheel is lowered by the guide wheel adjustment assembly so that the traction rope or cable does not contact the bottom of the guide wheel groove, does not leave the groove, and does not exceed the height of the limit roller. After the traction plate passes through this device, the original height of the lifting roller and guide wheel is restored.

[0016] The beneficial effects of this invention are:

[0017] This invention discloses a load-bearing overhead cable installation device. Lifting frames are installed on both sides of the guide wheel frame. The height of the guide wheel and the lifting rollers on both sides are adjustable. Limiting frames are also installed on both sides of the guide wheel, with limiting rollers that can be raised and lowered together with the guide wheel. During cable traction operations, each limiting roller engages with a groove on the guide wheel, supporting the cable from the bottom while simultaneously guiding and controlling the spacing of the cable laterally. This effectively prevents the cable from twisting or derailing due to traction torque, angular tension, wind load disturbances, etc., during traction. When the traction plate needs to pass the guide wheel, the height of the lifting rollers and the guide wheel can be adjusted by the lifting drive assembly and the guide wheel adjustment assembly, thereby adjusting the angle and height of the traction rope and cable entering and exiting the device. This prevents the traction plate from flipping or becoming stuck due to the height difference or traction angle between it and the guide wheel. Attached Figure Description

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0028] 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 a part of the embodiments of the present invention, and not all of them. 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.

[0029] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0030] like Figure 1As shown, a load-bearing overhead cable installation device of the present invention includes a base plate 5, on which a guide wheel frame 1 is mounted. A guide wheel 2 is rotatably mounted inside the guide wheel frame 1. The guide wheel 2 consists of a support wheel axle and multi-groove rollers rotatably mounted on the support wheel axle, for supporting and guiding multiple cables. A guide wheel adjustment assembly 8 is provided on the side of the guide wheel frame 1, which allows adjustment of the height of the guide wheel 2.

[0031] Limiting frames 9 are installed on both the front and rear sides of the guide wheel 2. The limiting frames 9 are fixedly connected to the end of the support axle of the guide wheel 2. When the height of the guide wheel 2 is adjusted by the guide wheel adjustment assembly 8, the limiting frames 9 rise and fall accordingly. Multiple limiting rollers 3 are installed on the limiting frames 9. The highest point of the limiting rollers 3 is higher than the bottom of the groove of the guide wheel 2 but lower than the top edge of the guide wheel 2. This allows the corresponding limiting rollers 3 to guide and limit the cable's side after it passes through the groove of the guide wheel 2. Simultaneously, it prevents the limiting rollers 3 from obstructing the traction plate when it passes through the guide wheel frame 1. Furthermore, by adjusting the lateral position of each limiting roller 3, the spacing between cables can be further controlled in conjunction with the grooves of the guide wheel 2. During cable traction, each limiting roller 3, in conjunction with the grooves of the guide wheel 2, further controls the spacing of the cables, preventing twisting or derailment due to traction torque, angular tension, wind load disturbance, etc.

[0032] Lifting frames 6 are connected to the front and rear sides of the base plate 5. Lifting frames 6 are equipped with lifting rollers 4 and lifting drive components 7. The height of the lifting rollers 4 can be adjusted via the lifting drive components 7. When the traction plate needs to pass over the guide wheel 2, the heights of the lifting rollers 4 and the guide wheel 2 can be adjusted via the lifting drive components 7 and the guide wheel adjustment components 8, respectively. This adjusts the angle and height of the traction rope or cable entering and exiting the device, preventing the traction plate from flipping or becoming stuck due to differences in height, traction angle, or other factors related to the guide wheel 2.

[0033] Furthermore, in one embodiment, such as Figure 4 As shown, the guide wheel adjustment assembly 8 includes a guide wheel adjustment motor 17. The output shaft of the guide wheel adjustment motor 17 is connected to a guide wheel adjustment screw 18. A second connecting block 19 is threaded onto the guide wheel adjustment screw 18. The second connecting block 19 is then connected to a second slide block 20, which is slidably connected to the side plate of the guide wheel frame 1. A sleeve plate 21 is fixedly installed on the end of the support wheel shaft of the guide wheel 2. A limiting frame 9 is connected to the sleeve plate 21. The second slide block 20 is connected to the end of the support wheel shaft of the guide wheel 2. When the guide wheel adjustment motor 17 is working, the guide wheel adjustment screw 18 and the second connecting block 19 can drive the second slide block 20 to rise and fall along the side plate of the guide wheel frame 1, thereby driving the guide wheel 2 and the limiting frame 9 to rise and fall together through the support wheel shaft of the guide wheel 2.

[0034] Furthermore, in one embodiment, such as Figure 5 As shown, the limiting frame 9 includes a connecting frame 23 connected to the socket plate 21. A second support plate 24 is connected to the end of the connecting frame 23. The second support plate 24 is provided with a guide rail plate 25 and fixing holes 27, located on both sides of the guide rail plate 25. Multiple adjusting slides 26 are slidably connected to the guide rail plate 25, and the adjusting slides 26 can be fixed to the second support plate 24 by bolts engaging with the fixing holes 27. The limiting rollers 3 are mounted on the adjusting slides 26, and the positions of each adjusting slide 26 can be adjusted according to actual operational needs, thereby adjusting the spacing of the limiting rollers 3 and their distance from the edge of the guide wheel 2 groove to accommodate different cable spacings.

[0035] Furthermore, in one embodiment, such as Figure 3 As shown, the lifting frame 6 includes a first support plate 10 connected to the base plate 5, a first upright plate 11 is provided on the first support plate 10, and an inclined plate is also connected between the first upright plate 11 and the base plate 5; a first slide block 12 is slidably connected to the first upright plate 11, and the lifting roller 4 is rotatably connected between the two first slide blocks 12.

[0036] The lifting drive assembly 7 includes a lifting motor 13 fixedly mounted on the first vertical plate 11. The output shaft of the lifting motor 13 is connected to a lifting screw 14. A first connecting block 15 is threaded onto the lifting screw 14. The first connecting block 15 is then connected to the first slide block 12. Thus, when the lifting motor 13 is working, the first slide block 12 is driven to rise and fall through the threaded engagement between the lifting screw 14 and the first connecting block 15, thereby realizing the automatic adjustment and control of the height of the lifting roller 4.

[0037] Furthermore, in one embodiment, such as Figure 6 As shown, a lateral adjustment mechanism is provided on the base plate 5. The lateral adjustment mechanism includes a guide frame plate 29 and a lateral movement motor 30. A lateral movement seat plate 28 is slidably arranged between the guide frame plates 29. The guide wheel frame 1 is set on the lateral movement seat plate 28. The output shaft of the lateral movement motor 30 is connected to a lateral movement screw 31, which is threadedly connected to the guide wheel frame 1. In actual operation, after the device is fixedly installed, interference between the traction rope and other components on the tower may occur. At this time, the lateral movement motor 30 can be started to adjust the lateral position of the guide wheel frame 1 to adapt to the complex installation and construction problems in actual operation.

[0038] Furthermore, in one embodiment, such as Figure 7As shown, a fixed connector 16 is provided at the bottom of the base plate 5. The fixed connector 16 includes a connector plate 32 and a long screw 33. When installing this device, the two connector plates 32 can be clamped on both sides of the crossbeam, and then the two can be connected by the long screw 33 to ensure the stability of the device installation and avoid the defects of low overall connection rigidity and poor anti-sway ability when installed by traditional hoisting or rope pulling methods.

[0039] A method of using a load-bearing overhead cable installation device includes the following steps:

[0040] S1. Fix this device on the crossarms of the two towers where the cable is to be laid;

[0041] S2. Pass the traction rope connected to the traction plate through the middle of the device, so that the traction rope is above the guide wheel 2 and the lifting roller 4 of the device; when pulling and releasing the line, the traction rope and the cable connected to the traction plate are both supported and guided by the guide wheel 2 on the device.

[0042] S3. When the traction plate is to pass through this device, the lifting roller 4 is first raised by the lifting drive assembly 7 so that it is supported under the traction rope or cable. Then, the guide wheel adjustment assembly 8 lowers the height of the guide wheel 2. The angle and height of the traction rope, cable and traction plate entering and leaving this device are adjusted so that the traction rope or cable does not contact the bottom of the groove of the guide wheel 2, does not leave the groove, and does not exceed the height of the limit roller 3. After the traction plate passes through this device, the original height of the lifting roller 4 and the guide wheel 2 are restored.

[0043] In summary, the load-bearing overhead cable installation device of the present invention can guide and further control the spacing of each cable from the side through the cooperation of each limiting roller 3 and the guide wheel 2, effectively preventing the cable from twisting or derailing due to traction torque, angular tension, wind load disturbance, etc. during the traction process; the lifting drive assembly 7 and the guide wheel adjustment assembly 8 can be used to adjust the height of the lifting roller 4 and the guide wheel 2 respectively, thereby adjusting the angle and height of the traction rope, cable and traction plate entering and leaving the device, preventing the traction plate from flipping or getting stuck due to the height between it and the guide wheel 2, the angle of traction force, etc.
