Description

Technical Field

[0001] The present invention relates to the technical field of cable laying auxiliary tools, and more specifically, it relates to a mechanical auxiliary tool for laying power grid cables. Background Art

[0002] Cables are one of the important components of the power grid. The laying of cables is the foundation for building the power grid. When laying cables, especially when laying them in underground pipelines, the coiled cables need to be straightened first and pre-laid beside the construction channel. At present, this work mainly relies on manual labor, and the specific operation is to drag the cables. Engineering cables can have a diameter of more than a dozen or even more than twenty centimeters and are extremely heavy. As the length of the straightened cables increases, the dragging difficulty also continuously increases, and the operation becomes more and more laborious towards the end, often requiring the cooperation of many construction workers. This not only leads to a high labor intensity of the workers but also seriously reduces the work efficiency. To solve this problem, construction workers often use guide wheels to assist in guiding and supporting the cables.

[0003] However, in a muddy environment, the cables are extremely likely to come into contact with the ground and adhere to mud. When these mud-adhered cables are laid into underground pipelines, it will affect the heat dissipation performance of the cables during normal use and pose a potential risk to the operation of the cables. Summary of the Invention

[0004] The present invention provides a mechanical auxiliary tool for laying power grid cables, which solves the technical problem that in the mechanical auxiliary tool for laying power grid cables in the related art, the cables are extremely likely to come into contact with the ground and adhere to mud, which will affect the heat dissipation performance of the cables during normal use.

[0005] The present invention provides a mechanical auxiliary tool for laying power grid cables, including a scraping bucket body, a guide wheel mechanism, and a jetting mechanism;

[0006] A cable slides through the middle parts of the scraping bucket body and the jetting mechanism, and the outer wall of the cable is in rolling cooperation with the guide wheel mechanism;

[0007] The jetting mechanism is located between the guide wheel mechanism and the scraping bucket body, and the guide wheel mechanism is in transmission cooperation with the jetting mechanism through the scraping bucket body. A dividing mechanism is slidably arranged at the conical end of the scraping bucket body, and the dividing mechanism is connected to the jetting mechanism;

[0008] When the cable passes through the guide wheel mechanism, the guide wheel mechanism drives the scraping bucket body to rotate. At the same time, the dividing mechanism rotates to divide the mud and cooperates with the scraping bucket body to complete the mud scraping work. During this process, the jetting mechanism acts in coordination to blow air on the cable. The dividing mechanism rotates and will move along the length direction of the cable, realizing self-cleaning while scraping and dividing the mud.

[0009] As a further optimized solution of the present invention, the guide wheel mechanism includes a support, a mounting plate and a guide wheel. The mounting plate is installed on the support and is rotatably connected to the guide wheel through a rotating rod. The rotating rod is in transmission cooperation with the scraping bucket body.

[0010] As a further optimized solution of the present invention, an internal gear ring is installed inside the scraping bucket body. The internal gear ring is meshed with a transmission gear. The transmission gear is fixedly sleeved with a transmission rod. One end of the transmission rod away from the transmission gear is fixedly sleeved with a conical follower gear. A conical driving gear in transmission cooperation with the conical follower gear is fixedly sleeved on the rotating rod.

[0011] As a further optimized solution of the present invention, the jetting mechanism includes an annular shell, a pulling rod, an inclined disk, a follower rod and a moving ring plate. The cable sequentially passes through the inclined disk and the annular shell. The inclined disk is connected to the scraping bucket body through a connecting rod. The annular shell is fixedly connected to the support through a connecting frame. The moving ring plate is slidably sleeved inside the annular shell. Spray holes are opened on both sides in the middle of the annular shell. One end of the pulling rod slidably extends into the annular shell and is fixedly connected to the moving ring plate. The other end is rotatably connected to the follower rod through a rotating shaft. And the number of the follower rods is two and they are arranged in parallel on both sides of the inclined disk.

[0012] As a further optimized solution of the present invention, the spray holes are inclined towards the cable and are distributed in a ring shape.

[0013] As a further optimized solution of the present invention, the dividing mechanism includes a plate body and a linkage rod. The number of the plate bodies is multiple and they are slidably arranged on the scraping bucket body at equal intervals. The plate body is connected with a rotating member. The rotating member is connected to the pulling rod through the linkage rod.

[0014] As a further optimized solution of the present invention, the rotating member includes a rotating ring and a connecting ring. The rotating ring is fixedly connected to the plate body. The connecting ring is rotatably sleeved on the rotating ring and is fixedly connected to the linkage rod.

[0015] As a further optimized solution of the present invention, an annular shielding portion is formed on the outer periphery of the scraping bucket body.

[0016] As a further optimized solution of the present invention, it further includes a plurality of guiding members for rolling support of the cable.

[0017] As a further optimized solution of the present invention, the moving length of the plate body is the same as the moving length of the pulling rod.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. An auxiliary tool for mechanical laying of power grid cables according to the present invention, by setting a separation mechanism, during the movement of the cable, the separation mechanism can pre-segment the soil adhering to the cable, dividing the larger pieces of soil into smaller pieces, which greatly facilitates the cleaning work of the scraping bucket body on the soil, significantly increasing the convenience of cleaning. At the same time, the cable acts on the guide wheel mechanism and operates together with the scraping bucket body. When the cable moves, the scraping bucket body cleans it, and with the pre-segmentation effect, the convenience of cleaning is increased. This cleaning method effectively reduces the influence of soil on the heat dissipation performance of the cable, avoids poor heat dissipation of the cable caused by soil attachment, thus ensuring the normal operation of the cable in the underground pipeline, reducing failures caused by heat dissipation problems, and further extending the service life of the cable.

[0020] 2. An auxiliary tool for mechanical laying of power grid cables according to the present invention, after setting the air jet mechanism, when the cable after preliminary cleaning moves to the position where the air jet mechanism is located, the cable will be affected by the air flow, and these air flows can remove the residual particles on the cable surface, effectively avoiding the situation that when the particles adhere to the cable surface and the cable contacts and moves relative to the guide wheel mechanism, the particles cause friction on the cable outer skin, thereby causing wear of the outer skin.

[0021] 3. An auxiliary tool for mechanical laying of power grid cables according to the present invention, when the scraping bucket body rotates, under the action of centrifugal force, the soil adhering to the scraping bucket body will be centrifugally thrown out, realizing the self-cleaning of the scraping bucket body. At the same time, the segmentation mechanism will make a reciprocating motion and enter the inside of the scraping bucket body, which is beneficial to the self-cleaning of the plate body in the segmentation mechanism and is conducive to reuse.

[0040] Now, the subject matter described herein will be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0041] As Figure 1 shown, a mechanical auxiliary tool for laying power grid cables according to an embodiment of the present invention includes a scraping bucket body 1, a guide wheel mechanism 2, and a jet mechanism 3;

[0042] A cable 4 is slidably penetrated through the middle of the scraping bucket body 1 and the jet mechanism 3, and the outer wall of the cable 4 is in rolling cooperation with the guide wheel mechanism 2;

[0043] The jetting mechanism 3 is located between the guide wheel mechanism 2 and the scraping bucket body 1, and the guide wheel mechanism 2 is in transmission cooperation with the jetting mechanism 3 through the scraping bucket body 1. A dividing mechanism 5 is slidably arranged at the conical end of the scraping bucket body 1, and the dividing mechanism 5 is connected to the jetting mechanism 3;

[0044] When the cable 4 passes through the guide wheel mechanism 2, the guide wheel mechanism 2 drives the scraping bucket body 1 to rotate. At the same time, the dividing mechanism 5 rotates to divide the soil, and cooperates with the scraping bucket body 1 to complete the soil scraping work. During this process, the jetting mechanism 3 acts in coordination to blow air on the cable 4. While the dividing mechanism 5 rotates, it will move along its length direction, realizing self-cleaning while scraping and dividing the soil.

[0045] During the laying operation, when the cable 4 rolls on the guide wheel mechanism 2, it acts on the guide wheel mechanism 2. Based on the transmission cooperation between the guide wheel mechanism 2 and the scraping bucket body 1, the guide wheel mechanism 2 drives the scraping bucket body 1 to rotate. The dividing mechanism 5 installed at the conical end of the scraping bucket body 1 also rotates accordingly. When the dividing mechanism 5 rotates, it can divide the larger pieces of soil adhered to the cable 4 into small pieces, so that the scraping bucket body 1 can scrape these soils more easily, realizing the preliminary cleaning of the soil on the surface of the cable 4.

[0046] The rotation of the scraping bucket body 1 can clean the soil on its surface under the action of centrifugal force.

[0047] At the same time, the jetting mechanism 3 is in transmission cooperation with the scraping bucket body 1 and the dividing mechanism 5. During the process of scraping the soil, the jetting mechanism 3 blows air on the cable 4 to further remove the remaining soil particles after scraping, enhancing the overall cleaning effect and reducing the damage of the particles to the outer skin of the cable 4 after the subsequent contact between the cable 4 and the guide wheel mechanism 2. It is worth mentioning that the dividing mechanism 5 can also move along the length direction of the cable 4 when rotating. It can not only clean the soil at different positions of the cable 4, but also realize self-cleaning during the movement, avoiding the influence of soil accumulation on the cleaning effect.

[0048] Automatically cleaning the soil on the surface of the cable 4 greatly reduces the manual cleaning burden and significantly improves the cleaning efficiency. Moreover, the synergistic effect of rotary scraping and blowing cleaning makes the cleaning more thorough, effectively reducing the influence of soil on the heat dissipation performance of the cable 4 and providing guarantee for the normal operation of the cable 4 in the underground pipeline.

[0049] Refer to Figure 2 the content, the guide wheel mechanism 2 includes a support 21, a mounting plate 22 and a guide wheel 23. The mounting plate 22 is installed on the support 21 and is rotatably connected to the guide wheel 23 through a rotating rod 24. The rotating rod 24 is in transmission cooperation with the scraping bucket body 1.

[0050] The support 21 bears the function of supporting the entire guide wheel mechanism 2. The mounting plate 22 installed on the support 21 provides a mounting position for the guide wheel 23. The guide wheel 23 is rotatably connected to the mounting plate 22 through a rotating rod 24. When the cable 4 rolls on the guide wheel 23, the guide wheel 23 will rotate around the rotating rod 24, and the rotating rod 24 is in transmission cooperation with the scraping bucket body 1. This enables the rotation of the guide wheel 23 to be transmitted to the scraping bucket body 1 through the rotating rod 24, driving the scraping bucket body 1 to rotate, thereby realizing the cleaning action of the soil on the surface of the cable 4, converting the movement of the cable 4 into the rotational power of the scraping bucket body 1. Its structure is simple and the transmission efficiency is high, effectively ensuring the smooth progress of the cleaning work.

[0051] Referring to Figure 2 As shown in the content, an internal gear ring 6 is installed inside the scraping bucket body 1. The internal gear ring 6 is meshed and connected with a transmission gear 7. The transmission gear 7 is fixedly sleeved with a transmission rod 8. One end of the transmission rod 8 far from the transmission gear 7 is fixedly sleeved with a conical follower gear 9. A conical driving gear 10 in transmission cooperation with the conical follower gear 9 is fixedly sleeved on the rotating rod 24.

[0052] When the guide wheel 23 rotates to drive the rotating rod 24 to rotate, the conical driving gear 10 fixedly sleeved on the rotating rod 24 rotates accordingly. Since the conical driving gear 10 is in transmission cooperation with the conical follower gear 9, the rotation of the conical driving gear 10 will drive the conical follower gear 9 to rotate. And because the conical follower gear 9 is fixedly sleeved on the transmission rod 8, the transmission rod 8 will also rotate accordingly, thereby driving the transmission gear 7 at the other end of the transmission rod 8 to rotate. The transmission gear 7 is meshed and connected with the internal gear ring 6 located inside the scraping bucket body 1. When the transmission gear 7 rotates, it drives the internal gear ring 6 to rotate, ultimately driving the scraping bucket body 1 to rotate, realizing the scraping operation of the soil on the surface of the cable 4, and transmitting the rotation of the guide wheel 23 to the scraping bucket body 1.

[0053] Referring to Figures 2 to 6 As shown in the content, the air jet mechanism 3 includes an annular shell 31, a pull rod 32, an inclined disk 33, a follower rod 34 and a moving ring plate 35. The cable 4 passes through the inclined disk 33 and the annular shell 31 in sequence. The inclined disk 33 is connected to the scraping bucket body 1 through a connecting rod 36. The annular shell 31 is fixedly connected to the support 21 through a connecting frame. The moving ring plate 35 is slidably sleeved inside the annular shell 31. Spray holes 311 are opened on both sides of the middle of the annular shell 31. One end of the pull rod 32 slides into the inside of the annular shell 31 and is fixedly connected to the moving ring plate 35. The other end is rotatably connected to the follower rod 34 through a rotating shaft. And the number of the follower rods 34 is two and they are arranged in parallel on both sides of the inclined disk 33. The transmission rod 8 slides through the annular shell 31 and the moving ring plate 35.

[0054] When the scraping bucket body 1 rotates, it will drive the swash plate 33 to rotate synchronously by means of the connecting rod 36. During the rotation of the swash plate 33, the follower rods 34 on both sides thereof will swing due to the rotation of the swash plate 33. This swing is transmitted through the rotating shaft, causing the draw rod 32 to move reciprocally within the ring shell 31. Since the draw rod 32 is fixedly connected to the moving ring plate 35, the moving ring plate 35 will move within the ring shell 31 together with the draw rod 32. During the movement, the air pressure inside the ring shell 31 is changed, prompting air to be ejected from the spray holes 311, thereby blowing and cleaning the cable 4, reducing the adverse effect of soil residue on the heat dissipation of the cable 4.

[0055] Further, the spray holes 311 are arranged to be inclined towards the cable 4 and are distributed in a ring shape.

[0056] It should be noted that the spray holes 311 are arranged to be inclined towards the cable 4 and are distributed in a ring shape. The inclined spray holes 311 enable the ejected air flow to directly impact the surface of the cable 4, and the generated impact force can blow off the soil. The ring-shaped distribution design can blow air on the cable 4 from multiple angles, ensuring that the soil at all positions in the circumferential direction of the cable 4 can be cleaned. In this way, this design effectively avoids cleaning dead corners, can clean the particles on the surface of the cable 4 more comprehensively and efficiently, significantly improves the thoroughness of cleaning, and thus guarantees the heat dissipation performance of the cable 4.

[0057] As a further optimized solution of the present invention, the dividing mechanism 5 includes a plate body 51 and a linkage rod 52. The number of plate bodies 51 is multiple, and they are slidably arranged on the scraping bucket body 1 at equal intervals. The plate body 51 is connected with a rotating member, and the rotating member is connected to the draw rod 32 through the linkage rod 52. The moving length of the plate body 51 is the same as the moving length of the draw rod 32. The plate body 51 is connected to the draw rod 32 by means of the linkage rod 52. When the draw rod 32 makes a reciprocating motion, the plate body 51 slides on the scraping bucket body 1 accordingly, and the moving length of the plate body 51 is consistent with that of the draw rod 32. This matching design ensures that the movement range of the plate body 51 on the scraping bucket body 1 coincides with the movement range of the draw rod 32, enabling the dividing mechanism 5 to divide and clean the soil on the surface of the cable 4 in a suitable area, effectively avoiding the situation where the soil in some areas cannot be cleaned properly, effectively improving the cleaning quality, and ensuring the effectiveness of the work of the dividing mechanism 5.

[0058] The draw rod 32 makes a reciprocating motion under the action of the air jet mechanism 3. This motion drives the rotating member connected to the plate body 51 through the linkage rod 52, and further causes the plate body 51 to slide and rotate on the scraping bucket body 1. During the rotation of the multiple plate bodies 51 arranged at equal intervals, the soil adhering to the cable 4 will be divided, breaking the larger pieces of soil into smaller pieces, making it easier for the scraping bucket body 1 to scrape. The way of first dividing and then scraping adopted by the dividing mechanism 5 greatly improves the cleaning efficiency of the soil on the surface of the cable 4, effectively reduces the cleaning difficulty, and significantly improves the cleaning effect.

[0059] As a further optimized solution of the present invention, the rotating member includes a rotating ring 53 and a connecting ring 54. The rotating ring 53 is fixedly connected to the plate body 51, and the connecting ring 54 is rotatably sleeved on the rotating ring 53 and fixedly connected to the linkage rod 52.

[0060] The pulling rod 32 drives the linkage rod 52 to move, and the connecting ring 54 moves together. Since the connecting ring 54 is rotatably sleeved on the rotating ring 53, the movement of the connecting ring 54 is transmitted to the rotating ring 53, causing the plate body 51 fixedly connected to the rotating ring 53 to move, realizing the operation of dividing the soil on the surface of the cable 4. The relative rotation setting of the rotating ring 53 and the connecting ring 54 enables the plate body 51 to slide along the scraping bucket body 1 while rotating, which can better adapt to the soil cleaning requirements at different positions on the surface of the cable 4, improving the flexibility of the movement of the plate body 51, enabling it to divide and clean the soil in different directions, and effectively improving the working efficiency and cleaning effect of the dividing mechanism 5.

[0061] As a further optimized solution of the present invention, an annular shielding portion 101 is formed on the outer periphery of the scraping bucket body 1.

[0062] The annular shielding portion 101 surrounding the outer periphery of the scraping bucket body 1 blocks the soil scraped off during the soil scraping process of the scraping bucket body 1 and confines it within a certain range.

[0063] As a further optimized solution of the present invention, it further includes a plurality of guiding members 11 for rolling support of the cable 4.

[0064] The guiding member 11 is composed of a guiding roller and a support frame. Since the cable 4 is relatively long, a plurality of them are arranged at intervals to provide rolling support for the part of the cable 4 after cleaning, effectively reducing the friction generated when the cable 4 moves, enabling the cable 4 to move more smoothly, and thus improving the laying efficiency of the cable 4.

[0065] Working principle:

[0066] During the laying process, the cable 4 is placed on the guiding wheel 23. When the cable 4 moves, it drives the guiding wheel 23 to rotate. The guiding wheel 23 is rotatably connected to the mounting plate 22 through the rotating rod 24, and the conical driving gear 10 fixedly sleeved on the rotating rod 24 rotates accordingly. The conical driving gear 10 is in transmission cooperation with the conical driven gear 9, thereby driving the transmission rod 8 to rotate. The transmission gear 7 on the transmission rod 8 also rotates. The transmission gear 7 meshes with the internal gear ring 6 inside the scraping bucket body 1, and finally drives the scraping bucket body 1 to rotate.

[0067] When the scraping bucket body 1 rotates, it drives the swash plate 33 to rotate through the connecting rod 36. The follower rods 34 on both sides of the swash plate 33 reciprocate accordingly. The follower rods 34 drive the pull rod 32 to reciprocate in the ring housing 31. The pull rod 32 is fixedly connected to the moving ring plate 35. The moving ring plate 35 moves in the ring housing 31, changing the air pressure inside the ring housing 31, so that air is ejected from the inclined and annularly distributed spray holes 311 to blow and clean the cable 4.

[0068] Meanwhile, the reciprocating motion of the pull rod 32 drives the rotating member to move through the linkage rod 52. The rotating member is composed of a rotating ring 53 and a connecting ring 54. The connecting ring 54 is fixedly connected to the linkage rod 52 and rotatably sleeved on the rotating ring 53. The rotating ring 53 is also fixedly connected to the plate body 51. This enables the plate body 51 to slide and rotate on the scraping bucket body 1. When the multiple equally spaced plate bodies 51 rotate, they divide the soil adhered to the surface of the cable 4. Moreover, the moving length of the plate body 51 is the same as the moving length of the pull rod 32, ensuring that the dividing mechanism 5 works in a suitable area. The scraping bucket body 1 then scrapes the divided soil. The dividing mechanism 5 can also move along the length direction of the cable 4 and achieve self-cleaning during the rotation process.

[0069] Multiple guide members 11 provide rolling support for the cable 4, reducing the friction when the cable 4 moves and improving the laying efficiency of the cable 4.

[0070] The above describes the embodiments of the present invention. However, these embodiments are not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
