Detailed implementation manners

[0015] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative efforts shall fall within the protection scope of the present utility model.

[0016] A wire laying device for transmission line construction, as shown in Figure 1 , 2As shown in Figures 3, 4, 5, 6, 7, 8, and 9, it includes two bases 1. Two vertical rods 2 are respectively and fixedly installed on the bases 1. The two vertical rods 2 on the same base 1 are symmetrically distributed front and back. Coaxial first rings 3 are respectively fixedly installed on the outer peripheries of the vertical rods 2. The two first rings 3 on the same base 1 are connected by a first connecting rod 4. The two ends of the first connecting rod 4 are sequentially fixedly connected to the outer peripheries of the two first rings 3 on the same base 1. Lifting devices are respectively provided on the first connecting rod 4. A wire winding roller 5 is placed between the two bases 1. A horizontal shaft 6 is provided in the hole at the center of the wire winding roller 5. The two ends of the horizontal shaft 6 respectively extend out of the wire winding roller 5. The lifting device can lift the wire winding roller 5 through the horizontal shaft 6 to be separated from the ground. Its characteristics are as follows: Coaxial second rings 7 are respectively movably provided on the outer peripheries of the vertical rods 2. The second rings 7 can not only slide up and down along the corresponding vertical rods 2 but also rotate along the corresponding vertical rods 2. The second rings 7 are located below the first rings 3. Limiting devices for restricting the rotation of the second rings 7 are respectively provided on the vertical rods 2. Motors 8 are respectively fixedly installed on the outer peripheries of the second rings 7. Coaxial friction wheels 9 are respectively fixedly installed on the output shafts of the motors 8. The axis of the friction wheel 9 is skew perpendicular to the axis of the wire winding roller 5. The output shafts of the motors 8 face the front side. The structure of the utility model is simple and ingenious. Through the frictional contact and cooperation between the friction wheel 9 and the wire winding roller 5, the wire winding roller 5 is driven to rotate, without manual rotation, which is relatively labor-saving, can meet the market demand, and is suitable for popularization. When using the utility model, place the bases 1 on the left and right sides of the wire winding roller 5, place the horizontal shaft 6 in the hole at the center of the wire winding roller 5, and make the left and right ends of the horizontal shaft 6 respectively extend out of the wire winding roller 5. Lift the horizontal shaft 6 and the wire winding roller 5 upward through the lifting device, release the limit of the second ring 7 by the limiting device and rotate the second ring 7 by ninety degrees. The rotation of the second ring 7 drives the motor 8 and the friction wheel 9 to rotate by ninety degrees around the axis of the corresponding vertical rod 2 until the axis of the friction wheel 9 is parallel to the axis of the wire winding roller 5, and the friction wheels 9 are respectively located below the wire winding roller 5. At this time, stop rotating the second ring 7 and limit the second ring 7 through the limiting device. Then drive the horizontal shaft 6 and the wire winding roller 5 to move downward through the lifting device until the outer peripheries at both ends of the wire winding roller 5 are in contact with the outer peripheries of the corresponding friction wheels 9. At this time, the outer peripheries of the friction wheels 9 are in frictional contact and cooperation with the outer peripheries at both ends of the wire winding roller 5. Start the motor 8, and the rotation of the output shaft of the motor 8 drives the corresponding friction wheel 9 to rotate. Since the friction wheel 9 is in frictional contact and cooperation with the outer peripheries at both ends of the wire winding roller 5, the friction wheel 9 can drive the wire winding roller 5 to rotate, thereby pulling off the wire wound on the wire winding roller 5.

[0017] Specifically, as shown in the figure, the jacking device in this embodiment includes two jacks 20, and the jacks 20 correspond to the first connecting rods 4 one by one. The jacks 20 are fixedly installed on the corresponding first connecting rods 4. Second connecting rods 21 are fixedly installed on the jacks 20 respectively. The fixed end of the jack 20 is fixedly connected to one side of the corresponding first connecting rod 4, and the movable end of the jack 20 is fixedly connected to one side of the corresponding second connecting rod 21. Third rings 22 are fixedly installed at both ends of the second connecting rod 21 respectively. The third rings 22 are located above the first ring 3. The third rings 22 correspond to the vertical rods 2 one by one. The third rings 22 are slidably installed on the outer periphery of the corresponding vertical rods 2. The third rings 22 are coaxially arranged with the corresponding vertical rods 2. Semi-circular through grooves 23 are respectively opened on the second connecting rod 21 corresponding to the horizontal shaft 6. The left and right sides and the upper side of the through groove 23 are respectively communicated with the outside. The outer periphery of both ends of the horizontal shaft 6 abuts and contacts with the inner periphery of the corresponding through groove 23. Control the movable ends of the jacks 20 to extend respectively. The extension of the movable ends of the jacks 20 drives the corresponding second connecting rods 21 to move upward. The upward movement of the second connecting rods 21 drives the corresponding third rings 22 to slide upward along the vertical rods 2. The second connecting rods 21 drive the horizontal shaft 6 and the winding roller 5 to move upward until they are separated from the ground.

[0018] Specifically, as shown in the figure, the limiting device in this embodiment includes four fourth rings 30. The fourth rings 30 correspond to the vertical rods 2 one by one. The fourth rings 30 are fixedly installed on the outer periphery of the corresponding vertical rods 2. The fourth rings 30 are respectively located below the second rings 7. Four bumps 31 are fixedly installed on the fourth rings 30 respectively. The four bumps 31 are evenly distributed in a circumferential manner about the axis of the fourth ring 30. Four grooves 32 are opened on the bottom of the second ring 7 corresponding to the bumps 31. The four grooves 32 are evenly distributed in a circumferential manner about the axis of the second ring 7. A spring 33 fixedly installed on the first ring 3 is provided between the first ring 3 and the corresponding second ring 7. The spring 33 is respectively sleeved on the outer periphery of the vertical rod 2. The upper end of the spring 33 is fixedly connected to the bottom of the corresponding first ring 3. The lower end of the spring 33 abuts and contacts with the top of the corresponding second ring 7. Under the elastic force of the spring 33, the bumps 31 on the fourth ring 30 are inserted and matched with the grooves 32 at the bottom of the second ring 7. When it is necessary to release the limit of the second ring 7 by the limiting device, move the second ring 7 upward. The spring 33 is compressed, so that the grooves 32 on the second ring 7 are no longer inserted and matched with the bumps 31 on the fourth ring 30. At this time, the second ring 7 can be rotated; rotate the second ring 7 by ninety degrees so that the output shaft of the left motor 8 faces to the right and the output shaft of the right motor 8 faces to the left. Then release the second ring 7. Under the elastic force of the spring 33, the second ring 7 moves downward. The four grooves 32 at the bottom of the second ring 7 are inserted and matched with the aligned bumps 31 on the fourth ring 30, thereby limiting the second ring 7.

[0019] Further, as shown in the figure, at one end of the friction wheel 9 away from the motor 8, coaxial extension rods 40 are fixedly installed respectively. On the left and right sides of the outer periphery of the extension rod 40, cross rods 41 are fixedly installed respectively. U-shaped plates 42 are sleeved on the outer periphery of the extension rod 40 respectively. The U-shaped plate 42 includes a cross plate and two vertical plates. The two vertical plates are located on the left and right sides of the extension rod 40, and the cross plate is located on the lower side of the extension rod 40. C-shaped through slots 43 are respectively opened on the left and right sides of the U-shaped plate 42 corresponding to the cross rods 41. The C-shaped through slot 43 includes a vertical slot and two horizontal slots. The upper and lower ends of one side of the vertical slot are respectively communicated with the horizontal slots. The cross rod 41 is slidably installed in the corresponding C-shaped through slot 43. Support rods 44 are fixedly installed at the bottoms of the U-shaped plates 42 respectively. Support plates 45 are fixedly installed on the support rods 44 respectively. The upper end of the support rod 44 is fixedly connected to the bottom of the corresponding U-shaped plate 42, and the lower end of the support rod 44 is fixedly connected to the top of the corresponding support plate 45. The support plate 45 can support on the ground. When the friction wheel 9 is to be used to drive the winding roller 5 to rotate, the support plate 45 needs to support on the ground, so as to give the friction wheel 9 an upward supporting force. Move the U-shaped plate 42 forward to make the cross rod 41 slide relative to the C-shaped through slot 43 to the lower end of the vertical slot of the C-shaped through slot 43, and then move the U-shaped plate 42 downward until the cross rod 41 contacts the top of the vertical slot of the C-shaped through slot 43, and then move the U-shaped plate 42 backward. The movement of the U-shaped plate 42 drives the corresponding support rod 44 and support plate 45 to move, so that the cross rod 41 is located in the upper horizontal slot of the corresponding C-shaped through slot 43. At this time, the support plate 45 supports on the ground.

[0020] Further, as shown in the figure, hard rubber 50 is fixedly arranged in the gaps between two adjacent teeth of the friction wheel 9 in this embodiment. When the winding roller 5 is made of steel or iron, the friction between the teeth of the friction wheel 9 and the winding roller 5 is small. At this time, the hard rubber 50 can increase the friction between the friction wheel 9 and the winding roller 5, so that the friction wheel 9 can more easily drive the winding roller 5 to rotate.

[0021] Furthermore, as shown in the figure, several traveling wheels 60 are rotatably installed on one side of the base 1 away from the vertical rod 2. When the device is to be moved, hold the upper end of the vertical rod 2 and rotate the device along the rotation axis of the traveling wheels 60 until the traveling wheels 60 contact the ground. It is more convenient and labor-saving to move the device through the traveling wheels 60.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
