Description

Technical Field

[0001] This invention belongs to the technical field of cable laying auxiliary equipment, specifically a straightening device for laying cables for power equipment. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods, including overhead, underground (ducts and direct burial), underwater, wall, and tunnel laying. Choosing the appropriate cable laying method is crucial for ensuring the transmission quality, reliability, and ease of construction and maintenance. For cable laying in trenches, due to the cable's own bending and twisting caused by transportation and tension, straightening equipment is used to straighten the cable in straight sections.

[0003] In existing technologies, when laying cables for power equipment, the straightening process for cables located in straight trenches typically involves using upper and lower arc-shaped pressure plates fitted over the outside of the cable and manually pushing it along the straight trench. However, this method is cumbersome in practice, relying on manual pulling force. Straightening the cable requires squeezing along its surface, but the squeezing position deviates during this process, resulting in poor straightening performance. Furthermore, manual straightening is difficult to control, leading to uneven pressure distribution across the pressure area and hindering convenient and effective straightening operations, resulting in unsatisfactory performance.

[0004] Furthermore, in the existing technology for laying cables for power equipment, due to the long length of straight trenches, the existing straightening methods are generally inefficient for straightening cables after laying for a certain length. The continuous straightening operation consumes a lot of manpower and requires pauses and breaks, making it difficult to achieve convenient and efficient straightening of cables in long straight trenches, resulting in poor performance. Summary of the Invention

[0009] Preferably, the connecting plate has an inner hole, and a fixing ring is fixedly sleeved on the inner surface of the inner hole. There are two movable cones, and a second spring is fixedly connected between the movable cones. The second spring is located inside the fixing ring.

[0010] Preferably, the side of the connecting plate is provided with a through hole, and the two ends of the through hole are respectively connected to the second pipe and the inner hole.

[0015] 1. This invention utilizes two sets of vertically distributed frames, No. 1 and No. 2, along with straightening rollers within them. During straightening, the cable is placed between the two sets of straightening rollers and pressed together with a telescopic rod. Pneumatic action pushes the movable plug and movable plate laterally. After the cable arrangement is complete, pneumatic propulsion enables the cable to be rolled and straightened laterally.

Simultaneously, under the elastic tension of spring one in the sleeve, the vehicle body rolls forward via the bottom rollers. Combined with the threaded rod in the fixing mechanism, this completes the automatic forward movement after straightening. For cables laid in long trenches, this invention provides a continuous and convenient straightening effect, saving manpower and improving the efficiency of straightening long-distance cables. It is convenient to use and simple to operate.

[0017] 3. This invention utilizes the slots and bolts on the connecting plate, along with the side holes on the movable plate, to change the height of the connecting plate and adapt to the depth of the groove. It can also be fixed after being moved upwards, completing the upward movement of the straightening part. Furthermore, the fixing mechanism can be disassembled after unscrewing the locking cap. Thus, when moving the straightening device, it can be moved conveniently and efficiently using the vehicle body. It is easy to adjust and move for laying multiple sets of cables in different locations, making it convenient to use. Attached Figure Description

[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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 9As shown, this embodiment of the invention provides a straightening device for laying cables in power equipment, including a vehicle body 1. A vertical plate 2 is fixedly connected to the top surface of the vehicle body 1. A sleeve 3 is fixedly sleeved on the side of the vertical plate 2. A movable plug 18 is movably sleeved on the inner surface of the sleeve 3. A movable plate 4 is fixedly connected to the side of the movable plug 18. A connecting plate 5 is fixedly connected to the outer end face of the movable plate 4. A first frame 6 and a second frame 7 are arranged from top to bottom below the connecting plate 5. A fixed shaft 8 is fixedly connected inside both the first frame 6 and the second frame 7. A straightening roller is movably sleeved on the outer surface of the fixed shaft 8. 9. A top block 10 is fixedly connected between the top surface of frame 6 and connecting plate 5. A second plate 12 is fixedly connected to the side of connecting plate 5. A first plate 11 is fixedly connected to the side of frame 7. A telescopic rod 13 is fixedly installed on the bottom surface of the second plate 12. The bottom surface of the telescopic rod 13 is fixedly connected to the first plate 11. An air pump 14 is fixedly installed on the top of the vehicle body 1. A first pipe 16 is fixedly connected to the end face of sleeve 3. A first valve 15 is fixedly connected to the air outlet of air pump 14. One end of the first valve 15 is fixedly connected to the first pipe 16. A fixing mechanism 29 is provided at the front of the vehicle body 1.

[0030] First embodiment: as follows Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when straightening is required, the vehicle body 1 is moved above the laying trench, and the cable to be straightened is first inserted into the adapter slot 292 in the fixing mechanism 29. The bottom threaded rod 294 is rotated, causing the threaded rod 294 to move the clamping plate 295 upward and press the cable, so that the cable is inserted along one side of the first frame 6 and the second frame 7, so that the cable is located between the upper and lower sets of straightening rollers 9. The telescopic rod 13 is then activated, causing the telescopic rod 13 to move the lower straightening roller 9 upward, so that the cable is pressed against the upper and lower sets of straightening rollers. Between 9, the air pump 14 is started, so that the air pump 14 introduces air into the sleeve 3 through the first valve 15 and the first pipe 16. As the air is continuously introduced into the sleeve 3, the internal air pressure increases and pushes the movable plug 18 to move, so that the movable plug 18 drives the movable plate 4 to slide. At the same time, the first spring 19 is stretched, and when the movable plate 4 moves, it drives the connecting plate 5 to move. The connecting plate 5 drives the first frame 6 and the second frame 7 below to move laterally. The cable located between the two sets of straightening rollers 9 is straightened forward by pressure and rolling thrust, completing the straightening operation.

[0031] First, by utilizing two sets of vertically distributed frames 6 and 7, along with the straightening rollers 9 within them, the cable is placed between the two sets of straightening rollers 9 during straightening. This is then secured with the telescopic rod 13. Pneumatic action pushes the movable plug 18 and movable plate 4 laterally. After the cable arrangement is complete, pneumatic propulsion enables the cable to be rolled and straightened laterally. The upper and lower straightening rollers 9 apply pressure and rolling thrust to the cable, effectively straightening it. This process reduces manual labor during straightening, achieving a stable and efficient straightening effect through pneumatic thrust. The resulting cable straightening quality is high, and the performance is excellent.

[0032] The sleeve 3 has a fixed connection to one end of a No. 1 spring 19, and the other end of the No. 1 spring 19 is fixedly connected to the movable plug 18. By utilizing the elasticity of the No. 1 spring 19, the sleeve 3 can be pulled and relatively reset under the fixation of the connecting plate 5, and the device can move forward automatically to complete the long-distance straightening operation.

[0033] The side of the connecting plate 5 is fixedly connected to the side tube 20, and the inside of the side tube 20 is movably sleeved with the movable cone 21. The connecting plate 5 and the first valve 15 are fixedly connected to the second tube 28. The outer surface of the first tube 16 is provided with the second valve 17. By using pneumatic thrust, the movable cone 21 is pushed to move laterally, so that the movable cone 21 is inserted into the grooves on both sides, and the front end is completely positioned, which facilitates subsequent forward movement. The second valve 17 is used to release the air pressure in the sleeve 3, so that after the pressure is released, the first spring 19 drives the vehicle body 1 forward.

[0034] The connecting plate 5 has an inner hole 22 inside, and a fixing ring 23 is fixedly sleeved on the inner surface of the inner hole 22. There are two movable cones 21, and a second spring 25 is fixedly connected between the movable cones 21. The second spring 25 is located inside the fixing ring 23. By utilizing the elasticity of the second spring 25, it is ensured that after the starting thrust is removed, the movable cones 21 on both sides can be pulled to reset and the front end fixation can be released.

[0035] The connecting plate 5 has a through hole 24 on its side. The two ends of the through hole 24 are connected to the second pipe 28 and the inner hole 22, respectively. Gas is transported from the second pipe 28 to the inner hole 22 by using the through hole 24.

[0036] The connecting plate 5 has a slot 26 on its side, and the inner surface of the slot 26 is movably sleeved with the movable plate 4. The connecting plate 5 has a bolt 27 threaded on its side, and the movable plate 4 has a side hole 33 on its side. There are two bolts 27 distributed vertically. By rotating the bolts 27 into the side hole 33 of the movable plate 4, the clamping and fixing are completed. The positions of the connecting plate 5 and the lower straightening roller 9 are adjusted to ensure that the vehicle body 1 can move stably on the ground after rising.

[0037] The fixing mechanism 29 includes a fixing frame 291, an adapter groove 292, a mounting plate 293, a threaded rod 294, and a clamping plate 295. The mounting plate 293 is movably mounted on the front end of the vehicle body 1. The fixing frame 291 is fixedly connected to the bottom surface of the mounting plate 293. The adapter groove 292 is opened inside the fixing frame 291. The threaded rod 294 is threaded onto the bottom surface of the fixing frame 291. The clamping plate 295 is fixedly connected to the top surface of the threaded rod 294 and located inside the adapter groove 292. By using the fixing mechanism 29, one end of the cable is clamped and fixed, ensuring that one end of the cable is fixed stably when straightened, preventing the cable from being pulled away directly. The adapter groove 292 is "T"-shaped, which facilitates the cable to be inserted and clamped and fixed with the clamping plate 295.

[0038] The vehicle body 1 has a mounting groove 30 on its top surface. A fixing rod 31 is fixedly connected inside the mounting groove 30. The inner surface of the mounting groove 30 is movably sleeved with the mounting plate 293. The fixing rod 31 is movably sleeved inside the mounting plate 293. A locking cap 32 located above the mounting plate 293 is threaded onto the outer surface of the fixing rod 31. The fixing mechanism 29 is fixed by using the fixing rod 31 to sleeve the mounting plate 293 and cooperating with the locking cap 32. It can be removed and taken out when it needs to be moved on the ground.

[0039] Second embodiment: After straightening a section of cable, valve 15 is activated and pipe 16 is closed, allowing air pump 14 to deliver gas through valve 15 and pipe 28 to the through hole 24 of connecting plate 5. Air continuously flows through through hole 24 into inner hole 22. As the air pressure in inner hole increases, the air pushes the movable cone 21 in inner hole 22 to move laterally and insert outwards into both sides of the groove. The threaded rod 294 is manually loosened, and valve 17 is opened. As gas is released from sleeve 3, the internal air pressure decreases, and the first spring... Spring 19 drives movable plug 18 to quickly reset. With movable plate 4 and connecting plate 5 fixed by movable cone 21, spring 19 pulls sleeve 3 to reset, thereby moving vehicle body 1 and upright plate 2. As vehicle body 1 moves forward along the top of the groove, after completing the forward movement, threaded rod 294 is tightened again and valve 15 is activated again to release gas in pipe 28. After movable cone 21 is reset by spring 25, air pump 14 is restarted and valves 15 and 2 are activated to achieve the next straightening operation of the segment distance.

[0040] First, by using the opening and closing actions of valve 15 and valve 17, the gas direction is switched. The gas volume provided by air pump 14 is used to straighten and fix the front connecting plate 5. Under fixation, the gas in sleeve 3 is depressurized. At the same time, under the elastic tension of spring 19 in sleeve 3, the vehicle body 1 rolls forward through the bottom rollers. With the help of the threaded rod 294 in the fixing mechanism 29, the straightened cable can move forward automatically. For cables laid in long trenches, it has a continuous and convenient straightening effect, thereby saving manpower and improving the efficiency of straightening long cables. It is convenient to use and easy to operate.

[0041] Furthermore, by utilizing the slots 26 and bolts 27 on the connecting plate 5, and in conjunction with the side holes 33 on the movable plate 4, the height of the connecting plate 5 can be changed to adapt to the depth of the groove. At the same time, it can be fixed after being moved upwards, completing the upward movement of the straightening part. Moreover, after unscrewing the locking cap 32, the fixing mechanism 29 can be disassembled. Thus, when moving the straightening device, the vehicle body 1 can be used to achieve convenient and efficient movement. It has the effect of easy adjustment and easy movement for multiple sets of cables laid in different locations, and is convenient to use.

[0042] Working principle and usage procedure: When straightening is required, the vehicle body 1 is moved above the laying trench, and the cable to be straightened is first inserted into the adapter slot 292 in the fixing mechanism 29. The bottom threaded rod 294 is rotated, causing the threaded rod 294 to move the clamping plate 295 upward and press the cable. The cable is then inserted along one side of the first frame 6 and the second frame 7, so that the cable is located between the upper and lower sets of straightening rollers 9. The telescopic rod 13 is then activated, causing the telescopic rod 13 to move the lower straightening roller 9 upward and press the cable firmly against the upper roller. Between the two sets of straightening rollers 9, the air pump 14 is activated, allowing air to be pumped into the sleeve 3 through valve 15 and pipe 16. As air continuously enters the sleeve 3, the internal air pressure increases, pushing the movable plug 18 to move. This causes the movable plug 18 to slide the movable plate 4, while the spring 19 is stretched. As the movable plate 4 moves, it also moves the connecting plate 5, causing the connecting plate 5 to move the lower frame 6 and frame 7 laterally. The cable located between the two sets of straightening rollers 9 is straightened forward under pressure and rolling thrust, completing the process. Straightening operation: After straightening a section of cable, valve 15 is activated and pipe 16 is closed, allowing air pump 14 to deliver gas through valve 15 and pipe 28 to the through hole 24 of connecting plate 5. Air continuously flows through through hole 24 into inner hole 22. As the air pressure in inner hole increases, the air pushes the movable cone 21 in inner hole 22 to move laterally and insert outwards into both sides of the groove. The threaded rod 294 is manually loosened, and valve 17 is opened. As gas is released from sleeve 3, the internal air pressure decreases, and spring 1... 19 drives the movable plug 18 to quickly reset. With the movable plate 4 and connecting plate 5 fixed by the movable cone 21, the first spring 19 pulls the sleeve 3 to reset, thereby causing the vehicle body 1 and the upright plate 2 to move. As the vehicle body 1 moves forward along the top of the groove, after completing the forward movement, the threaded rod 294 is tightened again and the first valve 15 is activated again to release the gas in the second pipe 28. After the second spring 25 pulls the movable cone 21 to reset, the air pump 14 is restarted and the first valve 15 and the second valve 17 are controlled to activate, realizing the next straightening operation of the segment distance.
