Description

Technical Field

[0001] The invention belongs to the technical field of wire-releasing devices, and relates to an electrical wire-releasing device for buildings. Background Art

[0002] Electricity is an important energy source related to the national economy and people's livelihood. Cables, as the transmission medium of electricity or information, play a vital role in the national economy. During the storage, transportation and use of cables, a reel is usually used to wind the cable on it. When it is needed, the reel is supported and erected by a pay-off device, and finally the cable is pulled out to complete the pay-off operation.

[0003] At present, when the reel is placed on the pay-off device, a lifting device is generally required. Since the reel is large and heavy, and is wound with cables, its gravity cannot be lifted by manpower. In addition, the reel needs to be loaded on a vehicle when it needs to be transported. For larger and heavier reels, a lifting device is used. This mechanical lifting method undoubtedly increases the operating cost. For some smaller and relatively lighter reels, a springboard is used to push the reel onto a trolley that can meet the transportation needs, and then position and transport it. This method of pushing the reel by manpower has higher requirements on the labor intensity of the operator. In the process of pushing the reel onto the vehicle, if the operator is physically exhausted, the reel may roll down, which may cause personal injury. At the same time, the operation is also time-consuming and labor-intensive. Therefore, we propose an electrical pay-off device for construction to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0021] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner, and the following embodiments and features in the embodiments can be combined with each other without conflict. Example

[0022] like Figure 1 - Figure 3 , Figure 6As shown, an electrical wire-laying device for buildings comprises a bottom plate 1, and wheels 2 for movement are arranged at the four corners of the bottom of the bottom plate 1, and a rotating plate 4 is arranged on the top of the bottom plate 1, and an arc-shaped strip plate 6 is formed integrally on one side of the rotating plate 4, and two first fixed blocks 12 are symmetrically fixedly connected to the top of the arc-shaped strip plate 6 on both sides, and a same rotating rod 14 is rotatably connected between the two first fixed blocks 12, and two connecting arms 15 are symmetrically fixedly sleeved on the outer wall of the rotating rod 14, and one end of the two connecting arms 15 is fixedly connected to the same connecting plate 17. By rotating the rotating rod 14, the connecting plate 17 can be driven to rotate by the two connecting arms 15, and when the connecting plate 17 and the bottom plate 1 are in a horizontal state, as shown in FIG. Figure 2 As shown, the bottom of the connecting plate 17 can contact the top of the bottom plate 1, thereby achieving the effect of overall stable support. The top of the rotating plate 4 is fixedly connected to the second servo motor 11, and the output shaft of the second servo motor 11 is fixedly sleeved with an active bevel gear 13, and the outer wall of the rotating rod 14 is fixedly sleeved with a driven bevel gear 16 meshing with the active bevel gear 13. When the second servo motor 11 is started, the meshing movement of the active bevel gear 13 and the driven bevel gear 16 can drive the rotating rod 14 to rotate, thereby driving the connecting arm 15 to rotate, thereby achieving the effect of adjusting the rotation of the connecting plate 17.

[0023] The electrical wire-releasing device also includes two groups of inserting barrel parts symmetrically arranged on one side of the connecting plate 17, which are used for supporting and inserting the wire reel 3. When the inserting barrel parts and the bottom plate 1 are in a horizontal state, the installation and removal of the wire reel 3 can be completed. When the inserting barrel parts rotate with the connecting plate 17, the wire reel 3 can be inserted upward and positioned above the bottom plate 1, so as to complete the transportation and wire-releasing work. The inserting barrel parts include a sliding block 21 connected to the side of the connecting plate 17 away from the connecting arm 15. A vertical strip 22 is integrally formed on the side of the sliding block 21 away from the connecting plate 17. A plug-in plate 26 for positioning and inserting the wire reel 3 is provided on the side of the vertical strip 22 away from the sliding block 21. A plug-in slot 261 for plugging and matching with the rotating shaft 7 on the wire reel 3 is provided on the side of the plug-in plate 26 away from the vertical strip 22. The wire reel 3 adopts the existing cylinder structure, and most of the current wire reels 3 position and install the rotating shaft 7 on the top through a mounting frame. Then, the transportation and unwinding operations are carried out. In order to facilitate the smooth rotation of the winding drum 3 during unwinding, a rotating connection method is generally adopted between the rotating shaft 7 and the winding drum 3, so that after the rotating shaft 7 is positioned, the winding drum 3 can ensure normal rotation under any circumstances; in this technical solution, the second servo motor 11 is first started, and the rotating rod 14 is driven to rotate through the engagement of the active bevel gear 13 and the driven bevel gear 16, and then the connecting plate 17 is driven to rotate to a horizontal state with the bottom plate 1 through the connecting arm 15, and is in contact with the top support of the bottom plate 1, such as Figure 1As shown, at this time, the two plug plates 26 are also in a horizontal state and extend out of the bottom plate 1. Then, the winding drum 3 can be rolled by manually pushing it, and the two rotating shafts 7 are respectively docked in the plugging notches 261 on the two plug plates 26, and the entire winding drum 3 is located between the two plug plates 26, which can play a role of limiting and resisting the winding drum 3; then the second servo motor 11 is started again to drive the connecting plate 17 to rotate and move, and the upward rotation of the plug plate 26 can drive the winding drum 3 to rotate and move upward together, and the winding drum 3 can be stably inserted through the plug plate 26, and the winding drum 3 will not fall during the upward rotation process; after the maximum rotation angle, as shown in FIG. Figure 8 As shown, the plug plate 26 is located above the bottom plate 1 and has a certain angle with the bottom plate 1, so that the winding drum 3 is located above the bottom plate 1 and will not fall, and no additional fixing parts are needed to position the rotating shaft 7, and normal transportation and line-releasing work can be performed. Because there is a certain rotation resistance between the rotating shaft 7 and the plug-in slot 261 under the action of the gravity of the winding drum 3 itself, the rotating shaft 7 and the winding drum 3 are connected in a rotating manner, which can effectively ensure the normal rotation of the winding drum 3 when releasing the line.

[0024] The present invention can be used in the field of electrical wiring devices for buildings, and can also be applied to other fields of the present invention. Example

[0025] This embodiment is a further improvement of the previous embodiment: Figure 6 As shown, two third fixed blocks 19 are horizontally symmetrically fixedly connected to one side of the connecting plate 17 away from the connecting arm 15, and the same bidirectional screw 20 is rotatably connected between the two third fixed blocks 19, and two sliding blocks 21 are respectively threadedly sleeved on the positive and negative thread segments on the bidirectional screw 20, and the two sliding blocks 21 are both slidably connected to the connecting plate 17, and one end of the bidirectional screw 20 rotates through one side of one of the third fixed blocks 19 and is fixedly connected to a rotating handle 23. By turning the rotating handle 23 to drive the bidirectional screw 20 to rotate, the two sliding blocks 21 can be driven to move relative to each other, and then the two vertical strips 22 can drive the two plug plates 26 to move relative to each other; by adjusting the distance between the two plug plates 26, it can be adapted to the positioning and insertion of the winding drum 3 of different lengths, and after the winding drum 3 is positioned and inserted, the two plug plates 26 can be driven to move closer to each other so that the two plug plates 26 respectively contact and fit the two sides of the winding drum 3, which can prevent the winding drum 3 from rotating or shifting during the up and down rotation and transportation, thereby effectively improving the stability during rotation and transportation; when it is necessary to release the line, the rotating handle 23 is turned again to adjust the plug plates 26 to move away from each other by a short distance, as long as the normal rotation of the winding drum 3 can be guaranteed. Example

[0026] This embodiment is a further improvement of the previous embodiment: Figure 6 As shown, the side of the vertical strip 22 away from the sliding block 21 is symmetrically fixedly connected with two fourth fixed blocks 24, and the same guide rod 25 is fixedly connected between the two fourth fixed blocks 24, and the plug plate 26 is sleeved on the guide rod 25 and slidably connected with the vertical strip 22. The outer wall of the guide rod 25 is symmetrically sleeved with two springs 27, and the two ends of the spring 27 are respectively connected between the plug plate 26 and the fourth fixed block 24, and the upper and lower inner walls of the plug-in slot 261 are provided with inclined surfaces 2611; under the interaction of the elastic forces of the two springs 27, the initial state of the plug plate 26 is located in the middle position of the vertical strip 22. When the winding drum 3 is manually rolled to make the rotating shaft 7 dock with the plug-in slot 261, since the winding drum 3 is rolled along the ground, if the inner diameter of the winding drum 3 is too small, that is, the winding groove 261 is not smooth, the winding groove 261 is not smooth, and the winding groove 261 is not smooth. The reel 3 is smaller as a whole, and the height of its rotating shaft 7 is lower than the position of the plug-in slot 261. At this time, the rotating shaft 7 will conflict with the lower inclined surface 2611 in the plug-in slot 261, and the plug-in plate 26 will move downward as a whole, the lower spring 27 will be compressed, and the upper spring 27 will be stretched, so that the winding reel 3 can be inserted on the plug-in plate 26. On the contrary, if the inner diameter of the winding reel 3 is larger, that is, the winding reel 3 is larger as a whole, and the height of its rotating shaft 7 is higher than the position of the plug-in slot 261, the rotating shaft 7 will conflict with the upper inclined surface 2611 in the plug-in slot 261, and the plug-in plate 26 will move upward as a whole, the upper spring 27 will be compressed, and the lower spring 27 will be stretched, so that the winding reel 3 with different inner diameters can be inserted on the plug-in plate 26, thereby improving the practicality of the entire device. Two limit blocks 28 are symmetrically fixedly connected to one side of the vertical strip 22 away from the sliding block 21, and the two limit blocks 28 are respectively located between the plug plate 26 and the corresponding fourth fixed block 24. A clearance groove 281 is opened on one side of the top of the limit block 28 to cooperate with the guide rod 25. When the wire drum 3 is positioned and inserted by the plug plate 26, the entire wire drum 3 needs to be rotated and lifted upward. At this time, the second servo motor 11 is started to drive the connecting plate 17 to rotate, and the plug plate 26 is driven to rotate upward, thereby driving the wire drum 3 to rotate and rise upward. In this process, the wire drum 3 and the wire wound thereon have a heavy weight. Therefore, when rotating upward and after rotating to the highest point, in the process of continuing to rotate downward, there will be a certain distance between the plug plate 26 and the limit block 28. During the rotation process, the plug plate 26 will produce a certain back and forth displacement on the vertical strip 22 due to the self-gravity of the wire drum 3. Therefore, by setting the limit block 28, the plug plate 26 can be limited in movement. That is, after the plug plate 26 moves to conflict with the limit block 28, it will no longer continue to squeeze the spring 27, so that the spring 27 will not be excessively squeezed, thereby extending the service life of the spring 27. Example

[0027] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 3 , Figure 6 As shown, the top of the connecting plate 17 is fixedly connected with a butt plate 29, and the top of the arc strip 6 is fixedly connected with a butt block 10 that cooperates with the butt plate 29. When the connecting plate 17 is turned over, it can drive the butt plate 29 to rotate synchronously, and after rotating to the maximum angle, the butt plate 29 just contacts the top of the arc strip 6 and conflicts with the butt block 10 at the same time, which can improve the overall support stability after the winding drum 3 is rotated, and is convenient for better transportation and line release. Example

[0028] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 5 As shown, the second fixing block 18 and the fifth fixing block 30 are fixedly connected to one side of the connecting plate 17 close to the connecting arm 15, and the same sliding rod 31 is rotatably connected between the second fixing block 18 and the fifth fixing block 30. The outer wall of the sliding rod 31 is slidably sleeved with two supporting rods 32, and the ends of the two supporting rods 32 away from the sliding rod 31 are rotatably connected to the same wire wheel 33; when the connecting plate 17 rotates upward to the top of the bottom plate 1, as shown in FIG. Figure 8 As shown, the sliding rod 31 can be rotated to extend the wire wheel 33 outward, and the rotation position of the wire wheel 33 can be adjusted according to the angle of the wire required, so that the wire wheel 33 can guide and pull the wire; at the same time, by sliding the two support rods 32, the pulling position of the wire wheel 33 can be adjusted to adapt to different wire laying requirements, thereby improving the flexibility of use. It should be noted that, if Figure 2As shown, when the connecting plate 17 needs to be rotated to a horizontal state, the wire wheel 33 needs to be rotated inward and retracted first to facilitate the normal rotation of the entire device. At the same time, after the connecting plate 17 is rotated to a horizontal state, the wire wheel 33 is located below the rotating rod 14, but the extended position of the wire wheel 33 cannot exceed the rotating rod 14, because the entire device rotates around the rotating rod 14. If it exceeds the rotating rod 14, the wire wheel 33 will conflict with the top of the base plate 1 during the rotation process due to its excessive length, resulting in the inability to rotate and move. Therefore, if it exceeds the limit, the entire device cannot be rotated normally. If more traction needs need to be met, the support rod 32 can be designed as a telescopic rod according to actual conditions. When in use, the support rod 32 is rotated outward, and then the length is adjusted to meet more usage needs. One end of the slide bar 31 rotates through one side of the fifth fixed block 30 and is fixedly sleeved with a sleeve rod 34. One side of the sleeve rod 34 is threadedly connected with a positioning rod 35. One end of the positioning rod 35 away from the fifth fixed block 30 is fixedly connected with a turning handle 36. The side of the fifth fixed block 30 away from the second fixed block 18 is provided with a plurality of equidistant arc-shaped positioning holes 301 for use with the positioning rod 35. When the slide bar 31 needs to be rotated, the turning handle 36 is first turned to drive the positioning rod 35 to rotate, and one end of the positioning rod 35 is simultaneously moved out of the positioning hole 301. At this time, the support rod 32 can be driven to rotate by rotating the slide bar 31, and then the wire wheel 33 is rotated out. After adjusting the required traction angle, the turning handle 36 is turned again to drive the positioning rod 35 to rotate, so that one end of the positioning rod 35 is inserted into the corresponding positioning hole 301, thereby completing the rotation limit of the slide bar 31, thereby achieving the angle positioning effect of the wire wheel 33, and finally, the sliding support rod 32 is adjusted according to the required traction position. Example

[0029] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 3 , Figure 8 As shown, the bottom of the base plate 1 is fixedly connected with an L-shaped mounting plate 5, and the top of the L-shaped mounting plate 5 is fixedly connected with a first servo motor 8. The output shaft of the first servo motor 8 rotates and passes through the top of the base plate 1 and is fixedly sleeved with an adjusting gear 9. The outer wall of the arc strip 6 is provided with a plurality of tooth grooves 61 meshing with the adjusting gear 9, and the rotating plate 4 is rotatably connected to the top of the base plate 1 through an axis. By the meshing of the adjusting gear 9 and the tooth grooves 61, the arc strip 6 can be driven to rotate when the first servo motor 8 is started, thereby driving the rotating plate 4 to rotate, and at the same time driving the first fixed block 12, the connecting plate 17 and the plug plate 26 to rotate as a whole, thereby driving the winding drum 3 to adjust the angle; in the process of paying out the wire, by adjusting the angle of the winding drum 3, the paying out operation at different angles can be completed, and thus it can be suitable for the use requirements of different scenes. In the process of inserting and removing the winding drum 3, as shown in FIG. Figure 7As shown, in some restricted special environments, the insertion and removal work at different angles can be completed by adjusting the angle of the insertion plate 26, so that the whole device is more flexible and convenient to use.

[0030] In one aspect of this embodiment, two corners of the top of the bottom plate 1 close to the connecting plate 17 are both provided with chamfers 37, and the chamfers 37 are arranged with the rotation point of the rotating plate 4 as the center. Figure 7 As shown, by setting the chamfer 37, after adjusting the angle of the plug plate 26, the winding drum 3 can complete normal insertion and removal work without being affected by the corner of the base plate 1, and during the rotation of the connecting plate 17, it can always be supported and fitted on the top of the base plate 1 to ensure the support stability of the entire device.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the first servo motor 8 and the second servo motor 11 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
