Description

Technical Field

[0001] The present invention relates to the technical field of automatic wire hanging equipment, and particularly relates to a wire hook rack and an automatic wire hanging machine for transmission lines. Background Art

[0002] Wire hanging for transmission lines is an important step in the installation of transmission lines. Currently, the wire hanging work for transmission lines requires operators to manually operate to hang the hook on the load-bearing wire to fix the transmission line. In the construction of transmission line projects, generally, the one-dragging-one method is adopted. The wire clamp connects the transmission line to the wire hanging equipment, and then a winch is used to tighten the transmission line. When the pulling force reaches the design value, the staff makes a mark on the tower, wraps black tape around the transmission line directly below the wire hanging hole of the tower, then loosens the transmission line, and finally hangs the hook on the load-bearing wire and the transmission line passes through the hook. This traditional manual wire hanging work has the problem of low wire hanging efficiency and increases the labor intensity of the operators. Therefore, there is an urgent need for an automatic wire hanging equipment. Summary of the Invention

[0028] The hook 406 is a standard part of an existing wire hanging tool for transmission lines, such as Figure 7 As shown, the hook 406 includes an arc-shaped body and hook bodies arranged on both sides of the arc-shaped body. When the hook bodies are hooked on the bearing wire 7, the transmission wire 8 is supported by the arc-shaped body, as Figure 3 shown.

[0029] As Figures 1 to 8 shown, the present invention provides an automatic wire hanging machine 1 for transmission lines, which includes a box body 101, a hook disc 401, a hook rack 403, a hook rack driving device 5, and a traction device 3 arranged in the box body 101. The hook rack 403 is used to place the hook 406, and the hook rack driving device 5 is used to drive the hook rack 403 to move so that the hook 406 on the hook rack 403 can be automatically hooked on the bearing wire 7. The traction device is used to pull the automatic wire hanging machine of the present invention to move forward on the bearing wire.

[0030] As Figure 1 , 2 shown, a box cover 102 is also hingedly arranged on the box body. The box cover 102 is locked on the box body 101 through a snap lock 104. An inlet is arranged on one side of the box body 101, and an outlet 103 communicated with the inlet is arranged on the other side; a sorting wheel 2 for sorting the transmission wire 8 is arranged on the box body 101, and the sorting wheel 2 is hingedly arranged on the box body 101 below the outlet 103; a hanging space 105 is arranged in the box cover 102;

[0031] A traction device 3 and a driven traction wheel 6 for moving the box body 101 on the bearing wire 7 are arranged in the box cover 102. The traction device 3 includes a traction motor 301 and a crawler wheel riding on the bearing wire 7. The traction motor 301 provides power for the traction device 3 so that the crawler wheel can move on the bearing wire, so that the box body and the box cover move forward along the bearing wire; the transmission wire guide wheel 302 is fixedly arranged in the box body 101 and is used to separate the transmission wire from the bearing wire and ride on the transmission wire.

[0032] As Figure 2 , 3As shown in FIGS. 4, a rotatable hook disc 401 and a hook disc driving device 4 are provided inside the box body 101. A plurality of hook racks 403 are annularly distributed on the hook disc 401. When the hook disc driving device drives the hook disc to rotate, the next hook rack corresponds to the hook rack driving device, so that the next hook can be hooked on the carrying line, and continuous circulation can be carried out, so that a plurality of hooks can be hooked on the carrying line at a certain interval.

[0033] As Figure 3 , Figure 4 shown, the hook disc driving device includes a hook disc driving motor 413 and a hook disc driving gear 414. The output shaft of the hook disc driving motor 413 is connected to the hook disc driving gear 414. The hook disc 401 is an annular hook disc, and an annular rack meshing with the hook disc driving gear 414 is provided on the inner ring of the hook disc. When the hook disc driving motor 413 rotates, the hook disc driving gear 414 can be driven to rotate, and then the hook disc 401 can be rotated.

[0034] As Figure 3 shown, the hook disc is an annular disc, and a second guide sleeve 402 is further provided thereon. The second guide sleeve is a cylindrical barrel with a top and a through hole provided at the top. A plurality of the second guide sleeves 402 are annularly distributed on the hook disc 401. A hook rack 403 as shown in Figure 7 is installed in each second guide sleeve 402. The hook rack 403 can move up and down in the second guide sleeve 402. A return spring 405 is sleeved on the hook rack. One end of the return spring is connected to the bottom of the hook rack, and the other end is connected to the top of the second guide sleeve.

[0035] As Figure 7 , 8As shown, the hook rack 403 includes a hook rack body 408. An accommodation groove 409 is provided on the hook rack body 408. The accommodation groove 409 is used to accommodate the arc-shaped body on the hook. A permanent magnet is provided in the accommodation groove 409. The hook is generally made of iron. When the arc-shaped body is placed in the accommodation groove 409, the permanent magnet can adsorb the arc-shaped body so that the arc-shaped body is stably fixed in the accommodation groove 409. Blocks 410 are provided at both ends of the accommodation groove 409. The two blocks are arranged in parallel, which can not only play a guiding role to enable the arc-shaped body to quickly snap into the accommodation groove 409, but also play a certain fixing role. Stabilizing frames 411 are provided on the hook rack body 408 on both sides of the accommodation groove 409. In this embodiment, the stabilizing frame 411 is an accommodation groove 412 with a notch on one side. The notches of the two accommodation grooves 412 face the clockwise or counterclockwise direction with the accommodation groove 409 as the center. When hanging a line, one side of the accommodation groove 412 blocks the arc-shaped body so that the hook can only move in one direction, that is, the direction of the notch, and leave the hook rack, but cannot move in the opposite direction. One end of the hook rack body 408 is provided with a support rod 407, and a driven gear 404 is provided at the end of the support rod 407. When the hook is placed at the initial position in the hook rack, the hook is parallel to the box body 101, that is, parallel to the load line and the transmission line.

[0036] As Figure 3 , 5 , 6 shows that the hook rack driving device 5 includes a crank and connecting rod mechanism, a guide sleeve 506, and a push rod 503. The push rod 503 is movably arranged in the guide sleeve 506. The crank and connecting rod mechanism includes a turntable, a connecting rod 501 eccentrically hinged on the turntable, and a connecting rod 502 hinged on the connecting rod 501. The connecting rod 502 extends into the guide sleeve 506. A hook rack driving motor 508, a hook rack driving gear 509, and a hook rack driving gear 510. As Figure 4As shown, the output end of the hook rack driving motor 508 is connected to the first hook rack driving gear 509. The second hook rack driving gear 510 meshes with the first hook rack driving gear 509. The turntable is coaxially connected to the second hook rack driving gear 510. The first guide sleeve 506 is fixedly arranged in the box body 101. A spiral chute 507 is arranged on the first guide sleeve 506. One end of the push rod 503 is provided with a driving tooth 504. The driving tooth 504 is in one-way driving cooperation with the driven tooth 404. In some other embodiments, the connection manner between the push rod 503 and the driving tooth 504, and between the support rod 407 and the driven tooth 404 can also be added with a ratchet-type transmission structure to achieve one-way driving cooperation in the radial direction. In this embodiment, a convex block 505 that can slide along the spiral chute 507 is arranged on the push rod 503, so that the push rod 503 can perform spiral movement in the first guide sleeve 506 to push the support rod 407 to slowly rotate, causing the hook to rotate, so as to change the orientation of the hook 406 during the rising process. The tooth profiles of the driving tooth 504 and the driven tooth 404 are both triangular. The two working surfaces of the driving tooth are respectively a radial power surface and a non-radial power surface. The angle between the radial power surface and the horizontal plane is greater than 90° and less than 180°, and the angle between the non-radial power surface and the horizontal plane is greater than 150° and less than 180°. The tooth profile of the driven tooth is matched with that of the driving tooth. The push rod 503 slides up and down along the spiral chute 507. The driving tooth 504 can be in one-way cooperation with the driven tooth 404 to automatically hook the hook 406 on the hook rack 403 to the load line 7. Specifically, a return spring 405 is sleeved on the hook rack 403. When the push rod 503 slides upward along the spiral chute 507, the driving tooth on the push rod 503 contacts the driven tooth on the hook rack 403, but due to the tooth profile angle, the transmitted radial torque is not enough to overcome the friction between the support rod and the second guide sleeve. The push rod can push the hook rack 403 upward into the hanging space 105 without changing the orientation of the hook rack. The initial position of the hook is parallel to the load line, and the hook will not be blocked by the load line 7 during the rising process. The return spring 405 is in a compressed state. After that, when the push rod 503 slides downward along the spiral chute 507, due to the tooth profile angle and the action of the return spring 405 on the support rod, the hook rack 403 makes the driven tooth 404 cooperate well with the driving tooth 504. The push rod 503 rotates a certain angle when sliding downward, and then pushes the support rod to rotate a certain angle, that is, the hook rotates a certain angle to hook the hook 406 on the load line 7.

[0037] Working principle:

[0038] 1. Hang the wire-hanging machine on the load-bearing line, rotate the sorting wheel 2 upward and position it with a positioning pin. Then, open the box cover 102 so that the load-bearing line 7 passes through from the inlet and exits from the outlet, and the power transmission line 8 passes through from the inlet, passes under the power transmission line guide wheel 302, exits from the outlet, and is placed on the sorting wheel 2. Then, lock the box cover on the box body with a snap lock, completing the work of hanging the wire-hanging machine on the load-bearing line;

[0039] 2. The traction motor 301 drives the box body and the box cover to move forward along the load-bearing line, and the hook rack driving device drives the hook rack to move so that the hook is automatically hung on the load-bearing line. Specifically, when the hook rack driving motor 508 rotates to drive the second connecting rod 502 to move upward, the second connecting rod 502 can contact the push rod 503 and push the push rod 503 to slide upward along the spiral chute 507, thereby causing the hook rack to move upward, and the return spring is in a compressed state; when the second connecting rod 502 moves upward to the highest position, the hook bodies on both sides of the hook are located above the load-bearing line 7, and the power transmission line 8 passes through the arc-shaped body at the bottom of the hook. Then, the second connecting rod 502 moves downward, and the push rod slides downward along the spiral chute. At the same time, the return spring acts on the hook rack, enabling the driven gear on the hook rack to be better matched with the driving gear on the push rod. The push rod drives the hook rack to rotate, so that the hook rack can also rotate during the descending process, and further enabling the hook to rotate a certain angle during the descending process so that the hook bodies on both sides of the hook are hung on the load-bearing line. During the process of the hook rack continuing to move downward, the hook disengages from the hook rack, that is, the hanging work of this hook is completed;

[0040] 3. Drive the hook disc so that the next hook corresponds to the hook rack driving device, and then repeat the actions in step 2 to hang the next hook on the load-bearing line, and continuously cycle, so that multiple hooks can be hung on the load-bearing line at a certain interval.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
