A power transmission and distribution line erection device

Abstract

This utility model relates to the field of cable laying technology, specifically to a power transmission and distribution line laying device, comprising two parallel support plates. Both ends of the support plates are provided with ramps. A limiting component for upward unfolding and restricting the position of the cable reel is installed on the top of each support plate. A sinking component for controlling the unfolding of the limiting component by the weight of the cable reel is installed in the middle of each support plate. By setting the sinking component and the limiting component, the cable's own weight drives the swing arm to lift the limiting rollers to fit against both sides of the cable reel, forming a physical constraint. This provides a stable constraint on the cable reel from a high position, preventing swaying or displacement and significantly improving the stability of cable unwinding. Furthermore, for cable reels of different diameters, there is no need to adjust the roller spacing; the limiting rollers automatically fit against the cable reel, adapting to different sizes of cable reels, avoiding manual adjustment, and improving work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a device for laying power transmission and distribution lines. Background Technology

[0002] Transmission and distribution lines are key networks in the power system used for the transmission and distribution of electrical energy. Their function is to efficiently and safely transmit the electrical energy produced by power plants to the user end. The laying of cables is an important part of the construction of transmission and distribution lines. When laying cables, cable laying frames are needed to support the cable reels for laying.

[0003] A control cable release frame disclosed in Chinese Patent Publication No. CN222410545U is detachable and movable, allowing for flexible adjustment of the cable release position as needed. This solves the problem of traditional cable release frames being fixed, non-removable, and heavy, making them cumbersome and unable to flexibly adjust the cable release position according to actual needs. However, according to related technologies and existing technologies, this release frame mainly relies on support rollers on both sides to support the cable reel. These support rollers are positioned low, limiting the depth to which the cable reel sinks between the two support rollers. During cable unwinding, this structure struggles to provide sufficient stability, easily leading to swaying and deviation. Furthermore, the spacing of the support rollers must be manually adjusted for each cable reel of different diameters, increasing complexity and tediousness, consuming additional time and manpower, and reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a power transmission and distribution line erection device.

[0005] The purpose of this utility model is to provide a power transmission and distribution line erection device through the following technical solution, which includes two parallel support plates. Both ends of the support plates are provided with slopes. The top of each support plate is equipped with a limiting component for upward unfolding and restricting the position of the cable reel. The middle position of each support plate is equipped with a sinking component for controlling the unfolding of the limiting component by the weight of the cable reel.

[0006] Preferably, the sinking assembly includes a roller frame that is vertically slidably installed in the middle of the support plate. Two support rollers are rotatably installed inside the roller frame. The two support rollers are symmetrically arranged along the length of the support plate. Pressure plates are fixed on both sides of the roller frame, and grooves are formed on both pressure plates.

[0007] Preferably, the limiting assembly includes four rotating shafts fixed to both sides of the support plate. The four rotating shafts correspond to the two ends of the two support rollers respectively. A swing arm is rotatably installed on the outside of each rotating shaft. A sliding column is fixedly provided at the position of each swing arm corresponding to the sliding groove. One end of the sliding column extends into the sliding groove. A limiting roller is rotatably installed between each pair of coaxially installed swing arms.

[0008] Preferably, the two support plates are connected by a connecting rod, and two connecting rods are symmetrically arranged and slidably connected to the support plates.

[0009] Preferably, a recessed groove is provided at the position corresponding to the support plate and the roller frame.

[0010] Preferably, the limiting roller is located at the end of the swing arm away from the sliding column, and the support plate and the limiting roller are both provided with roller grooves at corresponding positions.

[0011] Beneficial effects:

[0012] This power transmission and distribution line erection device, by setting up a sinking component and a limiting component, uses the cable's own weight to drive the swing arm to lift the limiting rollers to fit against both sides of the cable reel, forming a physical constraint. This provides a stable constraint on the cable reel from a high position, preventing the reel from shaking or shifting, and significantly improving the stability of cable unwinding. At the same time, for cable reels of different diameters, there is no need to adjust the roller spacing; the limiting rollers can automatically fit against the cable reel, adapting to different sizes of cable reels, avoiding manual adjustment, and improving work efficiency.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0024] like Figures 1 to 7As shown, a power transmission and distribution line erection device includes two parallel support plates 1. Both ends of each support plate 1 are provided with ramps 7. Each support plate 1 has a limiting component 4 installed at its top to restrict the upward unfolding of a cable reel. Each support plate 1 has a sinking component 3 installed at its middle position to control the unfolding of the limiting component 4 by the weight of the cable reel. The two support plates 1 are connected by connecting rods 2, two of which are symmetrically arranged and slidably connected to the support plates 1. In use, the distance between the two support plates 1 is first adjusted by sliding along the connecting rods 2 according to the width of the cable reel. After adjustment, the cable reel is pushed so that both ends roll synchronously onto the two support plates 1 under the guidance of the ramps 7. The cable reel is then rolled to the position of the sinking component 3 and pressed onto the two sinking components 3. At this time, under the influence of the cable reel's own weight, the sinking component 3 will move downward, thereby controlling the limiting component 4 to unfold upward and restrict the cable reel, completing the placement of the cable reel. During this process, the limiting component 4 is unfolded by the cable's own weight. The entire placement process only requires pushing the cable reel, which is convenient and quick. Moreover, when facing cable reels of different diameters, there is no need to adjust the roller gap. The limiting component 4 can automatically restrict the cable reel and adapt to cable reels of different sizes. At the same time, the unfolded limiting component 4 can form a stable restriction on the cable reel, greatly improving the stability of cable unwinding.

[0025] like Figures 1 to 3 As shown, the sinking assembly 3 includes a roller frame 31 that is vertically slidably installed in the middle of the support plate 1. Two support rollers 32 are rotatably installed inside the roller frame 31. The two support rollers 32 are symmetrically arranged along the length of the support plate 1. Pressure plates 33 are fixed on both sides of the roller frame 31. Sliding grooves 34 are opened on both pressure plates 33. Sinking grooves 5 are opened at the corresponding positions of the support plate 1 and the roller frame 31. The cable reel is pushed so that its two ends roll synchronously onto the two support plates 1 under the guidance of the ramp 7, and roll it to the position of the roller frame 31, pressing it on the two pairs of support rollers 32. At this time, under the influence of the weight of the cable reel, the support rollers 32 will drive the pressure plates 33 on both sides of the roller frame 31 to move downward along the sinking grooves 5.

[0026] like Figures 1 to 7As shown, the limiting assembly 4 includes four rotating shafts 41 fixed to both sides of the support plate 1. The four rotating shafts 41 correspond to the two ends of the two support rollers 32 respectively. A swing arm 42 is rotatably mounted on the outside of each rotating shaft 41. A sliding column 44 is fixedly provided at the position corresponding to the sliding groove 34 of each swing arm 42. One end of the sliding column 44 extends into the interior of the sliding groove 34. A limiting roller 43 is rotatably mounted between each pair of coaxially mounted swing arms 42. The limiting roller 43 is located at the end of the swing arm 42 away from the sliding column 44. Roller grooves 6 are opened at the positions corresponding to the limiting rollers 43 on the support plate 1. When the pressure plate 33 moves downward, it presses down one end of the swing arm 42 through the sliding column 44 in the sliding groove 34, causing the swing arm 42 to rotate around the rotating shaft 41 and lift the limiting roller 43 in the roller groove 6 upward until the limiting roller 43 contacts the cable reel and cannot move upward. During the movement, the swing arm 42 can no longer rotate due to the limiting roller 43, thus fixing the position of the sliding column 44. The sliding column 44 then fixes the position of the roller frame 31 through the pressure plate 33, so that the cable reel is restricted between the limiting rollers 43 on both sides under the support of the support roller 32, completing the placement of the cable reel. During this process, the limiting rollers 43 on both sides are unfolded by the weight of the cable itself. The entire placement process only requires pushing the cable reel, which is convenient and quick. Moreover, when facing cable reels of different diameters, there is no need to adjust the distance between the two support rollers 32. The limiting rollers 43 can automatically fit against the cable reel, thus automatically adapting to cable reels of different sizes. At the same time, the limiting rollers 43 on both sides, which are in a high position, can form a stable restriction on the cable reel, greatly improving the stability of cable unwinding.

[0027] The work process is as follows:

[0028] S1: As Figure 1 As shown, when using it, first adjust the distance between the two support plates 1 by sliding along the connecting rod 2 according to the width of the cable reel;

[0029] S2: As Figure 1 and Figure 2 As shown, after adjustment, push the cable reel so that both ends roll synchronously onto the two support plates 1 under the guidance of the ramp 7, and roll it to the position of the roller frame 31, pressing it onto the two pairs of support rollers 32.

[0030] S3: As Figures 1 to 7 As shown, at this time, under the influence of the cable reel's own weight, the support roller 32 will drive the pressure plates 33 on both sides of the roller frame 31 to move downward along the sinking groove 5. The pressure plates 33 will press down one end of the swing arm 42 through the sliding column 44 in the sliding groove 34, so that the swing arm 42 rotates around the rotating shaft 41 and lifts the limiting roller 43 in the roller groove 6 upward.

[0031] S4: As Figures 1 to 7As shown, when the limiting roller 43 contacts the cable reel, it can no longer move. At this time, the swing arm 42 can no longer rotate due to the limiting roller 43, thus fixing the position of the sliding column 44. The sliding column 44 then fixes the position of the roller frame 31 through the pressure plate 33, so that the cable reel is restricted between the limiting rollers 43 on both sides under the support of the support roller 32, thus completing the placement of the cable reel.

[0032] S5: As Figure 1 and Figure 5 As shown, during the installation process, the limiting rollers 43 on both sides are unfolded by the weight of the cable itself. The entire installation process only requires pushing the cable reel, which is convenient and quick. Moreover, when facing cable reels of different diameters, there is no need to adjust the distance between the two support rollers 32. The limiting rollers 43 can automatically fit the cable reel, thereby automatically adapting to cable reels of different sizes.

[0033] S6: As Figure 6 As shown, the limiting rollers 43 on both sides, which are in a high position, can provide stable restriction to the cable reel, greatly improving the stability of cable unwinding.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
