Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and more specifically, to a power engineering cable laying frame that is easy to install. Background Technology

[0002] In power engineering, the cable laying frame is an important piece of equipment used in power line construction, especially in the erection of high-voltage transmission lines and power communication lines, where it plays a crucial role. The cable laying frame is used to accurately place the power line conductors onto designated towers or supports, ensuring that the cables are installed according to design requirements. The cable laying frame effectively avoids conductor damage or errors caused by improper manual operation. Furthermore, in large-scale power projects, the application of the cable laying frame significantly improves construction efficiency and safety. However, existing cable laying frames still have some shortcomings.

[0003] For example, utility model patent CN207293760U discloses a wire-laying frame, including a base, at least two rotating drums, and at least two rotating shafts. Its key feature is that one end of each rotating shaft is fixed to the base, a support plate is fixed to each rotating shaft near the base, and a rotating drum is fitted onto each rotating shaft with its bottom supported by the support plate. It is convenient to use; simply fix the device to the ground, then place multiple coils of wire onto each rotating drum, and manually pull the wire ends to move the coils. The wire coils will automatically rotate with the drums, and the wire will be automatically released. This wire-laying frame is simple to manufacture, has high wire-laying efficiency, is environmentally friendly, and can be reused. Its application in construction engineering can improve construction efficiency and save costs. However, while the above device can accommodate multiple coils, it cannot adjust the height of the two sides of the support frame to adjust the overall support height of the wire coils, making it inconvenient to load and unload the coils. Furthermore, existing wire-laying frames pose a risk of movement interference when the heights on both sides are uneven.

[0004] Therefore, we have made improvements to this and proposed an easy-to-install power line laying frame. Utility Model Content

[0005] The purpose of this utility model is to address the fact that existing pay-off frames cannot independently adjust the height of both sides to adjust the overall support height of the wire coil, making it inconvenient to load and unload the wire coil, and that existing pay-off frames pose a risk of movement interference when the heights of both sides are different.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: An easy-to-install power line laying frame can improve the above-mentioned problems.

[0007] The application is as follows: The system includes a first support plate, a second support plate on the side of the first support plate, a first lifting assembly mounted on the first support plate, a first motor mounted on the first support plate, a first screw fixedly connected to the output shaft of the first motor, a slider mounted on the outer side of the first screw, a first rotating rod rotatably mounted on the slider, a second rotating rod rotatably mounted on the first rotating rod, the second rotating rod being fixedly connected to the first support plate, a first connecting rod mounted on the second rotating rod, and a groove formed on the first connecting rod. A second lifting assembly is mounted on the second support plate, the second lifting assembly including an extension rod fitted into the groove, and a second connecting rod mounted on the extension rod.

[0008] As a preferred technical solution of this application, both the first support plate and the second support plate are provided with a connecting groove, and a third support plate is installed in the connecting groove.

[0009] As a preferred technical solution of this application, the slider and the first screw are connected by a thread, and the slider forms a sliding structure with the first support plate through the first screw.

[0010] As a preferred technical solution of this application, a protrusion is fixedly provided on the slider, and a groove for the protrusion to slide is provided in the first support plate.

[0011] As a preferred technical solution of this application, the protrusions are symmetrically distributed on both sides of the slider, and the outer wall of the protrusions and the inner wall of the groove are in contact with each other.

[0012] As a preferred technical solution of this application, a fixed shaft is fixedly connected to the slider, and the diameter of the middle part of the fixed shaft is smaller than the diameter of the two sides of the fixed shaft.

[0013] As a preferred technical solution of this application, a rotating groove is provided on the first rotating rod, and a radial gap is formed between the middle area of ​​the fixed shaft and the inner wall of the rotating groove.

[0014] As a preferred technical solution of this application, the second rotating rod and the first connecting rod are rotatably connected, and the inner wall of the groove and the outer wall of the extension rod are in contact with each other.

[0015] As a preferred technical solution of this application, a third rotating rod and a fourth rotating rod are rotatably mounted on the second connecting rod, the third rotating rod and the fourth rotating rod are rotatably connected, the fourth rotating rod is rotatably connected to the second support plate, a movable block is rotatably mounted on the third rotating rod, the movable block is slidably connected to the second support plate, a second motor is mounted on the second support plate, and a second screw is fixedly connected to the output shaft of the second motor.

[0016] As a preferred technical solution of this application, the second screw and the movable block are connected by a thread, and the connection between the movable block and the third rotating rod is the same as the connection between the slider and the first rotating rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By setting the first and second lifting components, the function of independently adjusting the support height on both sides of the device is realized. When the device is in use, the first support plate and the second support plate are placed on both sides of the winding reel, the first motor drives the first screw to rotate, the second motor drives the second screw to rotate, and then the slider drives the first rotating rod and the second rotating rod to rotate. The movable block drives the third rotating rod and the fourth rotating rod to rotate, thereby independently adjusting the support height on both sides of the device. After the winding reel is supported, the third support plate can be installed into the first support plate and the second support plate to complete the overall support and installation of the device, enhancing the overall stability of the device. 2. The device is equipped with a first connecting rod, a groove, a second connecting rod, and an extension rod. When the support heights on both sides of the device are not adjusted synchronously, the extension rod will slide in the groove, while maintaining the overall support effect of the device. The gap design between the fixed shaft and the rotating groove allows the device to self-adjust and operate smoothly even when the heights on both sides are not completely synchronized, making the device more durable and solving the problem of motion interference when the heights on both sides of the existing wire feeding frame are different.

[0025] Example 1: like Figures 1-4As shown, this embodiment proposes an easy-to-install power line laying frame, including a first support plate 1, a second support plate 2 disposed on the side of the first support plate 1, a first lifting assembly 3 mounted on the first support plate 1, the first lifting assembly 3 including a first motor 301 mounted on the first support plate 1, a first screw 302 fixedly connected to the output shaft of the first motor 301, a slider 303 mounted on the outer side of the first screw 302, a first rotating rod 304 rotatably mounted on the slider 303, a second rotating rod 305 rotatably mounted on the first rotating rod 304, the second rotating rod 305 being fixedly connected to the first support plate 1, and a second rotating rod 305 being mounted on the second rotating rod 305. The device includes a first connecting rod 306 with a groove 307. A second lifting assembly 4 is mounted on a second support plate 2. The first and second lifting assemblies 306 independently adjust the support height on both sides of the device. A first motor 301 drives a first screw 302 to rotate, causing a slider 303 to slide on the first support plate 1. This rotates the first rotating rod 304 and the second rotating rod 305, adjusting the height of the first connecting rod 306. This, in turn, cooperates with the second lifting assembly 4 to lift the winding reel. The second lifting assembly 4 includes an extension rod 407 fitted into the groove 307, with the second connecting rod 406 mounted on the extension rod 407. The extension rod 407 can move within the groove 307 when the lifting on both sides of the device is asynchronous, thereby improving the stability of the device during operation.

[0026] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, both the first support plate 1 and the second support plate 2 are provided with a connecting groove 7, and a third support plate 8 is installed in the connecting groove 7. The slider 303 and the first screw 302 are threadedly connected. The slider 303 forms a sliding structure with the first support plate 1 through the first screw 302. The sliding structure enables the slider 303 to move through the first screw 302 to realize the lifting and lowering function of the winding reel. After the third support plate 8 is installed in the connecting groove 7, the positions of the first support plate 1 and the second support plate 2 can be calibrated.

[0027] like Figure 4 As shown, in a preferred embodiment, based on the above method, a protrusion 309 is fixedly provided on the slider 303, and a groove 308 for sliding the protrusion 309 is provided in the first support plate 1. The protrusions 309 are symmetrically distributed on both sides of the slider 303. The outer wall of the protrusion 309 and the inner wall of the groove 308 fit together. The fit between the protrusion 309 and the groove 308 enables the slider 303 to move straight, ensuring the overall stability of the device.

[0028] like Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, a fixed shaft 5 is further fixedly connected to the slider 303. The diameter of the middle part of the fixed shaft 5 is smaller than the diameter of the two sides of the fixed shaft 5. A rotating groove 6 is formed on the first rotating rod 304. A radial gap is formed between the middle area of ​​the fixed shaft 5 and the inner wall of the rotating groove 6. The second rotating rod 305 and the first connecting rod 306 are rotatably connected. The inner wall of the groove 307 and the outer wall of the extension rod 407 fit together. When the heights of the two sides of the device are different, the combination... Figure 2 As can be seen, the extension rod 407 will be misaligned to adapt to the different height differences on both sides of the device, thereby enhancing the overall stability of the device.

[0029] like Figures 2-4 As shown, in a preferred embodiment, based on the above method, a third rotating rod 404 and a fourth rotating rod 405 are rotatably mounted on the second connecting rod 406. The third rotating rod 404 and the fourth rotating rod 405 are rotatably connected. The fourth rotating rod 405 is rotatably connected to the second support plate 2. A movable block 403 is rotatably mounted on the third rotating rod 404. The movable block 403 is slidably connected to the second support plate 2. A second motor 401 is mounted on the second support plate 2. A second screw 402 is fixedly connected to the output shaft of the second motor 401. 2 is threadedly connected to the movable block 403. The connection between the movable block 403 and the third rotating rod 404 is the same as the connection between the slider 303 and the first rotating rod 304. The device can adjust the movable block 403 in the same way as adjusting the slider 303. The second screw 402 is driven to rotate by the second motor 401. The second screw 402 drives the movable block 403 to slide in the second support plate 2, thereby adjusting the angle of the third rotating rod 404. The third rotating rod 404, together with the fourth rotating rod 405, changes the support height of the second connecting rod 406 so as to independently adjust the support height on both sides of the device.

[0030] Specifically, when using this easy-to-install power line laying frame: (e.g.) Figure 1 , Figure 3 and Figure 4 As shown, when the device is in use, the first support plate 1 and the second support plate 2 are placed on both sides of the winding reel, and the first connecting rod 306 and the second connecting rod 406 are moved into the inside of the winding reel. At this time, the first motor 301 drives the first screw 302 to rotate, causing the slider 303 to slide on the first support plate 1. The protrusion 309 and the groove 308 are used to limit the slider 303, thereby causing the first rotating rod 304 to rotate and drive the second rotating rod 305 to rotate. When the slider 303 slides towards the first motor 301, the first connecting rod 306 is raised.

[0031] like Figures 2-4 As shown, since the connection method between the movable block 403 and the third rotating rod 404 is the same as the connection method between the slider 303 and the first rotating rod 304, the device can adjust the movable block 403 in the same way as adjusting the slider 303. The second screw 402 is driven to rotate by the second motor 401, and the second screw 402 drives the movable block 403 to slide in the second support plate 2, thereby adjusting the angle of the third rotating rod 404. The third rotating rod 404, in conjunction with the fourth rotating rod 405, changes the support height of the second connecting rod 406. The first lifting assembly 3 and the second lifting assembly 4 are used to lift the winding reel, and the support height on both sides of the device can be adjusted independently. Since a radial gap is formed between the middle area of ​​the fixed shaft 5 and the inner wall of the rotating groove 6, the device can adapt to the height difference between the left and right sides. Furthermore, the extension rod 407 can move in the groove 307 when the lifting and lowering of the two sides of the device are asynchronous, so that the device can be adjusted from the height difference between the left and right sides. Figure 1 Transform into Figure 2 The state of the first support plate 1 and the second support plate 2 can be calibrated after the third support plate 8 is installed in the connecting groove 7.

[0032] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
