Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and more specifically, to a power cable transmission and laying device. Background Art

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. According to different application scenarios, cable laying methods can be divided into overhead, underground (including pipe placement and soil burial), underwater, wall and tunnel types. Reasonable selection of cable laying methods is crucial to ensuring the transmission performance, reliability of the line and subsequent construction and maintenance work.

[0003] In underground cable laying operations, especially when pipeline laying is adopted, when faced with large-span curved pipelines, the cable head transported inward is very likely to collide with the curved part of the pipe wall when reaching the curved part. This collision may not only damage the structure of the curved part of the pipeline, but also cause damage to the entry head of the cable, that is, the front end or joint part of the cable, thereby hindering the smooth progress of the entire cable transportation process.

[0004] To this end, the present application proposes a power cable transmission and laying device to solve the above-mentioned problems. Summary of the invention

[0007] In a new embodiment, the adjustment component includes: a servo motor, installed in the rear middle of the top end of the chassis; a toothed disc, installed at the bottom end of the twisting disc; a gear, arranged at the rear of the toothed disc and meshing with the toothed disc, the bottom end of the gear is rotatably installed at the rear of the bottom wall of the chassis, and the top end is fixedly connected to the output end of the servo motor.

[0008] In a new embodiment, the pneumatic assembly includes: two pneumatic cylinders 1, which are respectively installed at the rear of the left and right groove plates; a wall-attached roller column, which slides in the pneumatic cylinder 1, and the inward end of the wall-attached roller column is connected to the inner wall of the inner wall of the pneumatic cylinder 1 through a compression spring; two pneumatic cylinders 2, which are installed at the front of the left and right groove plates, and the pneumatic cylinders 2 on the left and right sides are in a front-to-back staggered state; two delivery pipes, which are located between the pneumatic cylinder 1 and the pneumatic cylinder 2, one end of the delivery pipe is connected to the tail end of the pneumatic cylinder 1, and the other end is connected to the head end of the pneumatic cylinder 2.

[0009] In a new embodiment, the pneumatic component also includes: a push column, which is slidably installed in the pneumatic cylinder 2; an arc-shaped push plate, which is installed at the inward end of the push column, and the inward end of the arc-shaped push plate is installed with a flexible plate surface; a tension spring, which is sleeved on the outside of the pneumatic cylinder 2, one end of which is connected to the outer wall of the pneumatic cylinder 2, and the other end of which is connected to the outer wall of the inward end of the push column.

[0010] In a new embodiment, the length of the conveying tube located at the bend of the outer diameter of the cable duct is greater than the length of the conveying tube located at the bend of the inner diameter of the cable duct.

[0011] In a new embodiment, the fixed pipe assembly includes: two vertical frames, which are installed on the inward end of the groove plates on the upper and lower sides; an electric push rod installed in the middle of the vertical frame; a trapezoidal frame plate, which is arranged on the inward side of the vertical frame, and the top of the trapezoidal frame plate is fixedly connected to the telescopic end of the corresponding electric push rod; and an airbag, which is installed on the left and right sides of the inner wall of the trapezoidal frame plate.

[0012] In a new embodiment, the fixed tube assembly also includes: an inflation port, installed in the middle of one side of the top end of the stand; an air frame tube, buried inside the trapezoidal frame plate, and one side of the top end of the air frame tube is connected to the inflation port; an air intake pipe, installed on the left and right sides of the bottom end of the air frame tube, and the two air intake pipes are respectively connected to the corresponding airbags.

[0013] In a new embodiment, a transverse baffle is installed at the rear end of the annular frame, and a displacement sensor is installed at the rear end of the transverse baffle.

[0014] Beneficial effects: Compared with the prior art, the advantages of the present invention are: 1. The power cable transmission and laying device consists of an external transmission device and an internal mobile transmission device. The external device is adjusted to align with the curvature of the cable duct entrance, and the internal device moves stably in the duct. The drive motor is started to push the cable. When it reaches the large-span curved part, the pneumatic component triggers the squeezing of the curved cable head to avoid collision while allowing subsequent cables to adapt to the curved direction.

[0015] 2. By setting up the air cylinder 1, the wall roller column, the compression spring, the air cylinder 2 and the conveying pipe, when the mobile conveying device passes through the curved part of the cable pipeline, the outer diameter and inner diameter bending parts squeeze the air cylinder 1 and the wall roller column respectively. Since the curvature at the inner diameter is large, the squeezing force is stronger, and the gas in the compressed air cylinder 1 generates high pressure, which is transmitted to the air cylinder 2 through the conveying pipe, pushing the inner push column and the arc-shaped push plate inward, effectively utilizing the squeezing force at the bending part.

[0016] 3. Use the extrusion force at the bend to drive the two inner push columns of the air pressure cylinder to move inward, thereby driving the connected arc-shaped push plate to squeeze the inside of the cable, so that small and medium-sized soft cables can be bent smoothly and then pass through the curved part of the pipeline to avoid collision, and can also effectively guide subsequent cable transportation.

[0017] 4. Because the air pressure component at the bend of the outer diameter of the cable conduit is subjected to a small extrusion pressure, it can resist the outside of the cable and provide a stable opposing force for the inner bend, ensuring that the cable bending is limited to the head, avoiding subsequent cable twisting or fluctuation, ensuring smooth flow and preventing damage.

[0018] 5. The upper and lower trapezoidal frame plates are driven by an electric push rod to clamp the cable head, and the airbag provides additional elastic clamping on four sides. The airbag is also quickly inflated using the inflation port, air frame tube and air inlet pipe to ensure that the cable head is stably and firmly fixed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0035] The embodiment of the present application solves the problem that when laying underground cable pipelines, the cable transportation is prone to collide with the curved part of the pipeline when facing a large-span curved pipeline by providing a power cable transportation and laying device. When in use, the cable is transported by an external transportation device, an internal mobile transportation device, a pneumatic component 15 and a fixed pipe component 16, so that when the cable reaches the large-span curved part of the cable pipeline 1, the curved cable head is squeezed to avoid collision while allowing the subsequent cables to adapt to the curved direction.

[0036] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows.

[0037] Example 1: Please refer to Figure 1-Figure 14, a power cable transmission and laying device, including a cable duct 1, and also includes: a chassis 2, which is arranged outside the cable duct 1 and placed parallel to the ground; a twisting disk 3, which is rotatably mounted on the bottom wall of the chassis 2; an adjustment component 4, which is installed inside the chassis 2 and is used to adjust the angle of the twisting disk 3; a lower frame 5, which is installed on the top of the twisting disk 3, and the middle part of the lower frame 5 is rotatably connected to a guide roller 6; an upper frame 7, which is slidably mounted on the upper part of the lower frame 5, and the middle part of the upper frame 7 is rotatably connected to a guide roller 8, and the central axis of the guide roller 8 is fixedly connected to the output end of a drive motor 9 fixedly mounted on the outer wall of one side of the upper frame 7; hydraulic rods 10, which are respectively mounted on the lower frame 5, and the telescopic ends of the two hydraulic rods 10 are fixedly connected to the lower left and right sides of the upper frame 7 respectively; the annular frame 11 is arranged inside the cable duct 1; four groove plates 12 are arranged, which are equidistantly installed on the outer wall of the annular frame 11, and the length of the left and right groove plates 12 is greater than that of the upper and lower groove plates 12; a sleeve 13 is installed in the middle of the upper and lower groove plates 12, and a spring roller column 14 is slid in the sleeve 13, and a pneumatic component 15 is installed in the middle of the left and right groove plates 12, and the pneumatic component 15 is triggered by passing through the curved part of the cable duct 1; a fixed pipe component 16 is installed at the inner end of the upper and lower groove plates 12, and is used to fix the inserted head of the cable.

[0038] In this example, see Figure 1-Figure 14 As shown, an external cable conveying device consisting of a chassis 2, a twisting plate 3, a lower frame 5 and an upper frame 7 is provided, and a mobile conveying device inside the cable duct 1 consisting of a ring frame 11 and a groove plate 12 is used in combination with each other to complete the conveying and laying operations of the cable in the cable duct 1 (large-span curved duct).

[0039] The specific steps of the power cable transmission and laying device are as follows: first, place the above-mentioned external cable transmission device at the entrance of the cable duct 1 where the cable needs to be transmitted, then use the adjustment component 4 to adjust the orientation of the twisting disk 3 and the lower frame 5 and the upper frame 7 installed thereon, so as to keep the axis center aligned with the curvature of the entrance of the cable duct 1, then place the cable to be transmitted between the guide roller 1 6 and the guide roller 2 8 assembled in the lower frame 5 and the upper frame 7, and adjust the distance between the lower frame 5 and the upper frame 7 by the hydraulic rod 10, so as to slide and clamp the cable to be transmitted, and the cable between the guide roller 1 6 and the guide roller 2 8 is extended into the head, and then fixed with the above-mentioned mobile transmission device by the fixed pipe component 16. After the fixing is completed, the above-mentioned entire mobile transmission device is sent into the cable duct 1 (the mobile transmission device contacts the upper and lower inner walls of the cable duct 1 through the sleeve 13 and the spring roller column 14, and then the air in the air pressure component 15 is used to adjust the distance between the lower frame 5 and the upper frame 7. The pressure cylinder 1501 and the wall-attached roller column 1502 contact the inner walls of the left and right sides of the cable duct 1 to maintain the stable movement of the above-mentioned mobile conveying device in the cable duct 1), and then start the drive motor 9 to drive the guide roller 2 8 to rotate, thereby pushing the cable and the mobile conveying device into the deeper part of the cable duct 1. As the transportation continues, the above-mentioned mobile conveying device will reach the large-span curved part in the middle of the cable duct 1. At this time, the pneumatic component 15 on the above-mentioned mobile conveying device will be triggered to squeeze and bend the cable head position, so that the inserted head of the cable will not contact and collide with the inner wall of the curved part of the cable duct 1, and the subsequent cable part will adapt to the curved direction, thereby promoting the smooth progress of the entire cable transportation process. After the cable passes through the curved part of the duct, the mobile conveying device will also be converted back to straight movement and move along the duct to the end outlet of the cable duct 1, having better internal self-adaptation ability of the cable duct 1.

[0040] For further information, see Figure 3 and Figure 4 The adjustment component 4 includes: a servo motor 401, installed at the rear middle of the top end of the chassis 2; a toothed disc 402, installed at the bottom end of the twisting disc 3; a gear 403, arranged at the rear of the toothed disc 402 and meshing with the toothed disc 402, the bottom end of the gear 403 is rotatably installed at the rear of the bottom wall of the chassis 2, and the top end is fixedly connected to the output end of the servo motor 401.

[0041] By setting up a linkage mechanism among the servo motor 401, the toothed disc 402 and the gear 403, the servo motor 401 drives the gear 403 to rotate, thereby driving the toothed disc 402 and the connected torsion disc 3 to rotate synchronously. On the one hand, it can ensure that the above-mentioned external cable conveying device placed at the entrance of the cable duct 1, wherein the guide rollers 1 6 and 2 8 in the lower frame 5 and the upper frame 7, can be kept aligned with the axial center of the curved entrance of the cable duct 1, so as to effectively guide it. On the other hand, for cable conveying scenarios with complex terrain, multiple external cable conveying devices can be added, thereby providing the necessary direction change function to adapt to the conveying adjustment required for the changes in long-distance cable conveying, and ensure smooth cable conveying.

[0042] For further information, see Figure 5 A transverse baffle 17 is installed at the rear end of the annular frame 11, and a displacement sensor 18 is installed at the rear end of the transverse baffle 17. By setting the transverse baffle 17, a rear resistance effect can be provided for the above-mentioned mobile conveying device to avoid the cable head placed in the fixed pipe assembly 16 from being exposed to the outside, and the length of the cable head can also be limited. By setting the displacement sensor 18, the position of the above-mentioned mobile conveying device moving in the pipe can be monitored, and the position of the above-mentioned mobile conveying device in the pipe can be monitored in real time in combination with an external wireless monitoring device.

[0043] Example 2: Please refer to Figure 5 , Figure 6 , Figure 10-12 The pneumatic assembly 15 includes: two pneumatic cylinders 1501, which are respectively installed at the rear of the left and right groove plates 12; a wall-attached roller column 1502, which slides in the pneumatic cylinder 1501, and the inward end of the wall-attached roller column 1502 is connected to the inner wall of the inner wall of the pneumatic cylinder 1501 through a compression spring 1503; two pneumatic cylinders 1504 are installed at the front of the left and right groove plates 12, and the left and right pneumatic cylinders 1504 are in a front-to-back misaligned state; two delivery pipes 1505 are provided and are located between the pneumatic cylinder 1501 and the pneumatic cylinder 2 1504, one end of the delivery pipe 1505 is connected to the tail end of the pneumatic cylinder 1501, and the other end is connected to the head end of the pneumatic cylinder 2 1504.

[0044] In the case where the air cylinder 1501, the wall roller column 1502, the compression spring 1503, the air cylinder 2 1504 and the conveying tube 1505 are provided, when the mobile conveying device mentioned in Example 1 passes through the inner curved portion of the cable conduit 1 (the inner curved portion includes the outer diameter curved portion and the inner diameter curved portion, such as Fig.13As shown), different extrusion situations will be encountered. Specifically, when the above-mentioned mobile conveying device reaches this position, the outer diameter bend and the inner diameter bend will respectively squeeze the air cylinder 1 1501 and the wall roller column 1502 on both sides (the compression spring 1503 is used to reset the wall roller column 1502). Since the curvature of the inner diameter bend is larger, the wall roller column 1502 in contact with the inner diameter bend will be subjected to a stronger inward extrusion force. This stronger extrusion force will further compress the gas in the air cylinder 1 1501 slidably connected thereto, generating high pressure. Subsequently, this high-pressure gas is transmitted to the air cylinder 2 1504 connected thereto through the conveying pipe 1505, pushing the subsequent push column 1506 in the air cylinder 2 1504 and the connected arc-shaped push plate 1507 to move inward, thereby realizing the effective utilization of the extrusion force generated when passing through the inner diameter bend of the cable duct 1.

[0045] Furthermore, the pneumatic assembly 15 also includes: a push column 1506, which is slidably installed in the pneumatic cylinder 1504; an arc-shaped push plate 1507, which is installed on the inward end of the push column 1506, and the inward end of the arc-shaped push plate 1507 is installed with a flexible plate surface 1508; a tension spring 1509, which is sleeved on the outside of the pneumatic cylinder 1504, one end of which is connected to the outer wall of the pneumatic cylinder 1504, and the other end is connected to the outer wall of the inward end of the push column 1506.

[0046] By setting a push column 1506, an arc-shaped push plate 1507, a flexible plate surface 1508 and a tension spring 1509, combined with the above-mentioned high-pressure gas, the push column 1506 in the air pressure cylinder 1504 is pushed inward, and this sliding action further drives the arc-shaped push plate 1507 connected thereto, so that it squeezes the inner side of the cable facing the inner diameter bend of the cable pipe 1 (suitable for the transportation and laying of small and medium-sized soft cables). The cable can smoothly produce the necessary bends, thereby easily passing through the curved part of the cable pipe, avoiding collision with the pipe wall, and effectively guiding subsequent cable transportation. Among them, the tension spring 1509 is used to reset the push column 1506, and the flexible plate surface 1508 can provide the arc-shaped push plate 1507 with a flexible contact effect with the outer wall of the cable.

[0047] At the same time, at the outer diameter bend of the cable duct 1, although the pneumatic assembly 15 also undergoes the above-mentioned similar squeezing operation, the squeezing force generated is correspondingly smaller because the curvature of the outer diameter bend is relatively small. This smaller squeezing force mainly acts to resist the outer side of the cable facing the outer diameter bend of the cable duct 1, providing a stable opposing force to the force received by the cable when it bends on the inner side ( Fig.14 As shown in the figure, the bending part of the cable is limited to a part of the head area, and will not cause unnecessary twisting or fluctuation of most of the subsequent cables. This design ensures that the cable can pass through the bending part smoothly and avoids potential damage to the cable due to excessive twisting.

[0048] For further information, see Fig.14 The length of the conveying pipe 1505 located at the bend of the outer diameter of the cable pipe 1 is greater than the length of the conveying pipe 1505 located at the bend of the inner diameter of the cable pipe 1. By setting the length of the conveying pipe 1505, the basic condition is provided for the left and right side air pressure cylinders 1504 to be in a front-to-back misaligned state, which is convenient for providing a reverse resistance force for the outer side of the cable facing the bend of the outer diameter of the cable pipe 1.

[0049] Example 3: Please refer to Figure 6-Figure 8 The fixed pipe assembly 16 includes: a stand 1601, which is provided with two and is installed at the inward end of the upper and lower side groove plates 12; an electric push rod 1602, which is installed in the middle of the stand 1601; a trapezoidal frame plate 1603, which is provided on the inward side of the stand 1601, and the top of the trapezoidal frame plate 1603 is fixedly connected to the telescopic end of the corresponding electric push rod 1602; an air bag 1604, which is installed on the left and right sides of the inner wall of the trapezoidal frame plate 1603.

[0050] Through the support of the stand 1601, the electric push rod 1602, the trapezoidal frame plate 1603 and the airbag 1604, the upper and lower trapezoidal frame plates 1603 are driven inward by the electric push rod 1602 to clamp the extended head of the cable between the upper and lower trapezoidal frame plates 1603. After the clamping action is completed, the airbags 1604 on the left and right sides of the trapezoidal frame plate 1603 provide additional elastic clamping force to ensure the stability and adaptability of the clamping.

[0051] Furthermore, the fixed tube assembly 16 also includes: an inflation port 1605, installed in the middle of one side of the top end of the stand 1601; an air frame tube 1606, buried inside the trapezoidal frame plate 1603, and one side of the top end of the air frame tube 1606 is connected to the inflation port 1605; an air intake pipe 1607, installed on the left and right sides of the bottom end of the air frame tube 1606, and the two air intake pipes 1607 are respectively connected to the corresponding airbags 1604.

[0052] Through the inflation port 1605, the air frame tube 1606 and the air inlet pipe 1607, the inflation port 1605 is connected to an external gas generating source (manual operation is required) to achieve gas injection. The injected gas flows in sequence through the air frame tube 1606 connected to the inflation port 1605, and the air inlet pipe 1607 connected to the air frame tube 1606, and finally provides inflation for the air bags 1604 on both sides. This process ensures that the air bags 1604 can be fully expanded, thereby implementing a stable and firm fixation on the cable head, thereby enhancing the overall stability and safety.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
