Description

Technical Field

[0001] This invention relates to the field of cable installation technology, and more specifically, to a cable laying and pulling device. Background Technology

[0002] In fields such as power engineering and communication engineering, cable laying and traction is a core process in line laying. Its quality and efficiency directly affect the stability of subsequent line operation and project progress. With the expansion of project scale and the upgrading of cable specifications, higher requirements are placed on the stability, cable protection capabilities and adaptability of cable laying and traction equipment.

[0003] In cable laying and traction operations in power and communication engineering, traditional UAV-based cable laying is an auxiliary method for long-distance, complex terrain scenarios such as mountainous areas, river crossings, and dense building clusters. Generally, the UAV first pulls a primary guide rope with a smaller diameter from one tower to another. Then, the primary guide rope pulls a secondary guide rope with a slightly larger diameter, and so on, until finally a main traction rope with a larger diameter is used. The main traction rope is connected through a traction plate, and the traction equipment pulls the transmission line through a guide wheel or pulley block to complete the cable laying operation.

[0004] However, guide wheels and pulley blocks can only provide unidirectional support. When pulling at corners, the cable is prone to rigid friction with the edge of the wheel groove and the equipment housing, resulting in scratches on the cable sheath and damage to the insulation layer. This requires a lot of manpower for subsequent inspection and repair, increasing project costs. In addition, the traction rope is prone to come out of the traction wheel groove or the cable can slip off the guide wheel. Especially during long-distance traction, once "rope running" or "line derailment" occurs, the operation must be interrupted and readjusted, which not only delays the construction period but may also damage the laid section due to cable dragging. The cable laying efficiency is low. In view of this, we propose a cable laying and pulling device. Summary of the Invention

[0005] The purpose of this invention is to provide a cable laying and pulling device to solve the technical problem of low cable laying efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a line-laying traction device, including a trolley module, the trolley module including a frame, the frame including a base, a traction mechanism being provided at the top of the base, a plurality of mounting cavities being provided on the base, and a cable mechanism being provided on the mounting cavities; The mounting cavity includes a mounting groove formed at the top of the base, and arc-shaped grooves are formed on both sides of the mounting groove; The cable mechanism includes two arc blocks A, which are movably disposed at both ends of the bottom of the mounting groove. Arc blocks B are rotatably disposed at both ends of the eccentric side of each arc block A. A movable arc groove is formed on the eccentric side surface of each arc block B. A movable block is movably disposed on the movable arc groove. The movable block is fixedly connected to the bottom end of the arc groove. Arc block B is movably engaged with the mounting groove. The bottom end of arc block A is elastically connected to the bottom end of the mounting groove through an elastic component. At least one rotating wheel assembly is provided on the concentric side surface of arc block A and arc block B. Under the weight of the cable, the elastic component compresses, causing the two arc blocks B and A to contact end-to-end, forming a ring structure. This allows several rotating wheel assemblies to form a ring-shaped rotating cavity. Through structural design of the cable mechanism, this invention, in its initial state, allows the two arc blocks B to separate under the elastic force of the elastic component, with the outer surface of arc block B contacting the surfaces of the two arc grooves. When the cable enters, under its own weight, the elastic component compresses, causing the two arc blocks B and A to contact end-to-end, forming a ring structure. This allows several rotating wheel assemblies to form a ring-shaped rotating cavity with equal spacing, providing all-around flexible clamping for the cable. Compared to traditional guide wheel structures, where the guide wheel axis is not parallel to the direction of the traction cable, causing lateral sliding between the conductor and the wheel surface, and cable offset relative to the wheel groove, leading to frictional wear, the ring-shaped rotating cavity of this invention provides all-around protection for the cable. Even during corner traction, it avoids cable offset caused by turning forces, reducing or even isolating cable wear, thereby reducing subsequent inspection work for workers.

[0007] Preferably, a U-shaped block is fixed at the top of the base, and two hanging plates are fixed at the top of the U-shaped block in a symmetrical structure. Several threaded grooves are evenly opened in the middle of the top of the base.

[0008] Preferably, a horizontal plate is fixed on both sides of the top of the base, and a semi-circular block A is fixed at both ends of the horizontal plate. A guide group is provided at the top of the base relative to any two gaps in the mounting slots. The guide group includes two circular blocks B, and the two circular blocks B are respectively fixed at the top of the base relative to the positions of the two semi-circular blocks A.

[0009] Preferably, a rotating groove is provided on each of the two circular blocks B located in the middle, and a chamfer is provided at both ends of the rotating groove, and an arc-shaped sliding groove is provided at both ends of the middle part of the rotating groove.

[0010] Preferably, the bottom of the mounting groove has an arc-shaped structure, and lifting slides are provided on both sides of the bottom of the mounting groove. Both the arc block A and the arc block B are adapted to the bottom of the mounting groove. Both ends of the arc block A are provided with insertion arc grooves, and the insertion arc grooves are provided with snap-fit ​​grooves. The insertion arc block is slidably provided in the insertion arc grooves. The insertion arc block is provided with a movable groove. The movable groove is provided with a snap-fit ​​block. The snap-fit ​​end of the snap-fit ​​block has a trapezoidal structure. The snap-fit ​​block and the movable groove are elastically connected by a spring B. The snap-fit ​​block and the snap-fit ​​groove are snap-fitted together.

[0011] Preferably, the elastic component includes a slide rod fixed to the bottom end of the arc block A, the slide rod being slidably connected to the lifting slide groove, the bottom end of the slide rod having a slot, and the bottom end of the slot being elastically connected to the bottom end of the lifting slide groove by a spring A.

[0012] Preferably, the rotating wheel assembly includes a cable wheel with a diameter that gradually increases from the middle to both ends. Both ends of the cable wheel are rotatably connected to a triangular seat, which is fixedly connected to the inner surface of the arc block A, or the triangular seat is fixedly connected to the inner surface of the arc block B.

[0013] Preferably, the traction mechanism includes two rollers, which are respectively disposed in two rotating grooves. The rollers have traction grooves on their surfaces. A connecting shaft is fixed at the center of the rollers. Arc sliders are rotatably provided at both ends of the connecting shaft. The two arc sliders are slidably connected to the two arc grooves respectively.

[0014] Preferably, the traction mechanism further includes a rotating column, which is disposed in the gap between the two rollers, and a threaded rod is rotatably provided at the bottom end of the rotating column, the threaded rod being threadedly engaged with the threaded groove.

[0015] Preferably, the system further includes a traction plate, which includes a triangular plate. A connector A is fixedly provided at the head end of the triangular plate, and a Z-shaped plate is fixedly provided at the tail end of the triangular plate. A plurality of connectors B are fixedly provided at the tail end of the Z-shaped plate relative to the positions of the plurality of mounting slots.

[0016] The beneficial effects of this invention are: 1. This invention, through structural design of the cable mechanism, initially separates the two arc blocks B under the elastic force of the elastic component, with the outer surface of arc block B contacting the surfaces of the two arc grooves respectively. When the cable enters, the elastic component compresses under the weight of the cable, causing the two arc blocks B and arc block A to contact head to tail, forming a ring block structure. This allows several rotating wheel components to form a ring-shaped rotating cavity with equal spacing, providing all-round flexible clamping for the cable. Compared to the traditional guide wheel structure, where the guide wheel axis is not parallel to the direction of the traction cable, the conductor and wheel surface are prone to lateral sliding, causing the cable to deviate relative to the wheel groove and resulting in frictional wear. The ring-shaped rotating cavity of this invention provides all-round protection for the cable, preventing cable deviation caused by turning force even during corner traction, reducing or even isolating cable wear, thereby reducing subsequent inspection work for workers.

[0017] 2. The present invention further designs the arc block A so that when the two arc blocks B and arc block A are in contact at their ends to form a ring block structure, the locking block engages with the locking groove, thereby locking the two arc blocks B and arc block A. By utilizing the gravity of the cable, the stability of the annular rotating cavity is ensured, thereby further improving the cable mechanism's protection effect on the cable.

[0018] 3. The present invention also designs that both arc block A and arc block B are adapted to the bottom of the mounting groove, so that under the weight of the cable, spring A is compressed and the slide rod slides into the lifting groove. The arc surface at the bottom of the mounting groove provides support for the outer surface of arc block A and the bottom of arc block B of the ring block structure, thereby improving the support strength of the cable mechanism.

[0019] 4. The invention designs the cable wheels so that when two arc blocks B and arc block A come into contact head to tail to form a ring block structure, and two adjacent cable wheels come into contact, the annular rotating cavity formed by several cable wheels is almost closed, further improving the all-round protection effect of the cable.

[0020] 5. Through the structural design of the traction mechanism, the present invention allows the threaded rod to be fixed in the corresponding threaded groove according to the angle of the traction, so that the traction rope passes through one traction groove, the rotating column and the other traction groove in sequence to form a triangular traction path, thereby preventing the traction rope from running away.

Detailed Implementation

[0033] like Figures 1 to 11 As shown, the present invention relates to a wire laying and pulling device, which includes a trolley module 1 and a pulling plate 5, wherein the pulling plate 5 is adapted to the trolley module 1; In embodiments of the present invention, such as Figure 2 As shown, the trolley module 1 includes a frame 2, several cable mechanisms 3 and a traction mechanism 4.

[0034] In embodiments of the present invention, such as Figure 2 As shown, the frame 2 includes a base 21, a U-shaped block 22 is fixed at the top of the base 21, and two hanging plates 23 are fixed at the top of the U-shaped block 22 in a symmetrical structure.

[0035] In embodiments of the present invention, such as Figure 7 As shown, the base 21 has several mounting cavities, including a mounting groove 211 at the top of the base 21. The bottom of the mounting groove 211 has an arc-shaped structure, and several threaded grooves 213 are evenly provided in the middle of the top of the base 21.

[0036] In embodiments of the present invention, such as Figure 2 and Figure 3As shown, horizontal plates 214 are fixedly mounted on both sides of the top of the base 21, and semicircular blocks A215 are fixedly mounted at both ends of the horizontal plates 214. A guide assembly is provided at the top of the base 21 relative to any two mounting slots 211. The guide assembly includes two circular blocks B216, which are fixedly mounted on the top of the base 21 relative to the positions of the two semicircular blocks A215. The above-described configuration of the present invention, as... Figure 2 As shown, any two guide groups gaps and the horizontal plate 214 and its adjacent guide groups constitute the cable lowering cavity. The two horizontal plates 214, several round blocks B216 and U-shaped blocks 22 together constitute the guide structure of the traction plate 5. When the traction rope drives the traction plate 5 to pass through, it passes through the guide structure of the traction plate 5 formed by the two horizontal plates 214, several round blocks B216 and U-shaped blocks 22. The traction rope drives the traction plate 5 to pass through the top of the two horizontal plates 214 and several round blocks B216.

[0037] The two circular blocks B216 in the middle are each provided with a rotating groove 217, and both ends of the rotating groove 217 are provided with chamfers. Both ends of the middle part of the rotating groove 217 are provided with arc-shaped grooves 218.

[0038] In embodiments of the present invention, such as Figure 6 and Figure 8 As shown, several cable mechanisms 3 are respectively disposed on several mounting cavities. Each cable mechanism 3 includes two arc blocks A31, which are movably disposed at both ends of the bottom of the mounting groove 211. Arc blocks B32 are rotatably disposed at both ends of the eccentric side of each arc block A31. A movable arc groove 33 is formed on the eccentric side surface of each arc block B32. A movable block 34 is movably disposed on the movable arc groove 33. The movable block 34 is fixedly connected to the bottom end of the arc groove 212. Arc blocks B32 are movably engaged with the mounting groove 211. The bottom end of arc block A31 is elastically connected to the bottom end of the mounting groove 211 via an elastic component 35. At least one rotating wheel assembly 36 is provided on the concentric side surface of arc blocks A31 and B32. The present invention, through the above-described configuration, refers to… Figure 6 and Figure 8 It can be seen that, in the initial state, under the elastic force of the elastic component 35, the two arc blocks B32 separate, and the outer surface of the arc block B32 contacts the surfaces of the two arc grooves 212 respectively. When the cable enters, as... Figure 10As shown, under the weight of the cable, arc block A31 descends, elastic component 35 is compressed, two arc blocks B32 rotate relative to arc block A31, and movable arc groove 33 slides relative to movable block 34, so that the two arc blocks B32 and arc block A31 contact head to tail to form a ring block structure, so that several rotating wheel components 36 surround an annular rotating cavity arranged in an annular and equally spaced structure, forming an all-round flexible clamping of the cable. Compared with the traditional guide wheel structure, when the axis of the guide wheel is not parallel to the direction of the traction cable, the conductor and the wheel surface are prone to lateral sliding, the cable deviates relative to the wheel groove, and frictional wear occurs. The annular rotating cavity of the present invention provides all-round protection for the cable. Even when traction at an angle, it can avoid cable deviation caused by turning force, reduce or even isolate cable wear, thereby reducing the subsequent inspection work of workers.

[0039] In an embodiment of the present invention, reference is made to Figure 9 Both ends of the arc block A31 are provided with insertion arc grooves 311. The arc center line of the insertion arc groove 311 coincides with the rotation axis center line of the arc block A31 and the arc block B32. The insertion arc groove 311 is provided with a snap-fit ​​groove 312. The insertion arc groove 311 is slidably provided with an insertion arc block 313. The two insertion arc blocks 313 are fixedly connected to the two arc blocks B32 respectively. The insertion arc block 313 is provided with a movable groove 314. The movable groove 314 is movably provided with a snap-fit ​​block 315. The snap-fit ​​end of the snap-fit ​​block 315 has a trapezoidal structure. The snap-fit ​​block 315 and the movable groove 314 are elastically connected by a spring B316. The snap-fit ​​block 315 and the snap-fit ​​groove 312 are snap-fitted together. Through the above-described configuration, during the process of forming a ring block by the head-to-tail contact of two arc blocks B32 and A31, the insertion arc block 313 further inserts into the insertion arc groove 311, and the locking block 315 moves to contact with the arc block A31. Under the reaction force of the locking block 315, the locking block 315 is forced to move into the movable groove 314, and the spring B316 is compressed until the locking block 315 slides into the insertion arc groove 311. When the head-to-tail contact of the two arc blocks B32 and A31 is reached, the locking block 315 slides into the locking groove 312 in the insertion arc groove 311. Under the elastic force of the spring B316, the locking block 315 engages with the locking groove 312, locking the two arc blocks B32 and A31. By utilizing the gravity of the cable and the elastic structure, the stability of the annular rotating cavity is ensured, thereby further improving the protection effect of the cable mechanism 3 on the cable.

[0040] In an embodiment of the present invention, to ensure support strength, lifting slide grooves 210 are provided on both sides of the bottom end of the mounting groove 211. Arc blocks A31 and B32 are adapted to the bottom of the mounting groove 211. The elastic component 35 includes a slide rod 351 fixed to the bottom end of the arc block A31. The slide rod 351 is slidably connected to the lifting slide groove 210. A slot 352 is provided at the bottom end of the slide rod 351. The bottom end of the slot 352 is elastically connected to the bottom end of the lifting slide groove 210 via a spring A353. This allows the spring A353 to compress under the weight of the cable, causing the slide rod 351 to slide into the lifting slide groove 210. The arc surface at the bottom end of the mounting groove 211 provides support for the outer surface of the ring-shaped arc block A31 and the bottom end of the arc block B32.

[0041] In embodiments of the present invention, such as Figure 8 As shown, the rotating wheel assembly 36 includes a cable wheel 361, the diameter of which gradually increases from the middle to both ends. A triangular seat 362 is rotatably connected to both ends of the cable wheel 361. The triangular seat 362 is fixedly connected to the inner surface of the arc block A31, or the triangular seat 362 is fixedly connected to the inner surface of the arc block B32. Through the design of the cable wheel 361, the invention ensures that when two arc blocks B32 and arc block A31 are in contact end-to-end, forming a ring structure, and when two adjacent cable wheels 361 are in contact, the annular rotating cavity formed by several cable wheels 361 is nearly closed, further enhancing the all-around protection of the cable.

[0042] In embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the traction mechanism 4 includes a rotating column 43 and two rollers 41. The two rollers 41 are respectively disposed in two rotating grooves 217. A traction groove 42 is formed on the surface of the rollers 41. A connecting shaft 40 is fixed at the center of the rollers 41. Arc sliders 45 are rotatably disposed at both ends of the connecting shaft 40. The two arc sliders 45 are slidably connected to the two arc grooves 218 respectively. The rotating column 43 is disposed in the gap between the two rollers 41. A threaded rod 44 is rotatably disposed at the bottom end of the rotating column 43. The threaded rod 44 is threadedly engaged with the threaded groove 213. Through the structural design of the traction mechanism 4, this invention allows the threaded rod 44 to be threadedly fixed in the corresponding threaded groove 213 according to the angle of the traction. This allows the traction rope to pass through one traction groove 42, the rotating column 43, and the other traction groove 42 in sequence, forming a triangular traction path and preventing the traction rope from running away.

[0043] In an embodiment of the present invention, the traction plate 5 includes a triangular plate 51, both sides of the head end of the triangular plate 51 are provided with rounded corners, the head end of the triangular plate 51 is fixed with a connector A50, the tail end of the triangular plate 51 is fixed with a Z-shaped plate 52, and the tail end of the Z-shaped plate 52 is fixed with a plurality of connectors B53 at a position relative to a plurality of mounting grooves 211.

[0044] Working principle: This embodiment provides a line-laying traction device. During use, the traction angle is calculated based on the position of each tower, thereby fixing the threaded rod 44 in the corresponding threaded groove 213. Traction power is activated, and the traction rope drives the traction plate 5 to move. The traction rope sequentially passes through the traction groove 42 of one roller 41, the surface of the rotating column 43, and the traction groove 42 of the other roller 41, forming a triangular traction path to prevent the traction rope from deviating during pulling. When the traction plate 5 passes, the two horizontal plates 21... 4. Several round blocks B216 and U-shaped blocks 22 jointly guide the traction plate 5. The traction rope drives the traction plate 5 through the tops of the two horizontal plates 214 and several round blocks B216. The cables on several connectors B53 at the tail end of the Z-shaped plate 52 fall from several falling cavities and mounting slots 211 onto the cable pulleys 361 on several arc blocks A31. Under the weight of the cables, the arc blocks A31 descend, the slide rod 351 slides into the lifting slide groove 210, the spring A353 is compressed, and the two arc blocks B32 relative to the arc block A3 1. Rotation: The movable arc groove 33 slides relative to the movable block 34, causing the two arc blocks B32 and A31 to contact head-to-tail, forming a ring block structure. Two adjacent cable wheels 361 contact each other, and several cable wheels 361 form a nearly closed annular rotating cavity. The arc surface at the bottom of the mounting groove 211 provides support for the outer surface of the arc block A31 and the bottom of the arc block B32 in the ring block structure. During this process, the insertion arc block 313 is further inserted into the insertion arc groove 311, and the locking block 315 moves to contact the arc block A31, thus locking the arc block. The reaction force of block 315 causes the locking block 315 to move towards the inside of the movable groove 314, and the spring B316 is compressed until the locking block 315 slides into the insertion arc groove 311. When the two arc blocks B32 and arc block A31 are in contact head to tail, the locking block 315 slides into the locking groove 312 in the insertion arc groove 311. Under the elastic force of the spring B316, the locking block 315 engages with the locking groove 312, so that the two arc blocks B32 and arc block A31 are locked, ensuring the stability of the annular rotating cavity. like Figure 10 As shown, the annular rotating cavity provides all-around protection for the cable, preventing cable deviation caused by turning force even when pulling at an angle, reducing or even isolating cable wear, thereby reducing the workload of subsequent inspections by workers.

[0045] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
