Description

Technical Field

[0001] The invention relates to the technical field of cable stripping, in particular to a central beam tube type OPGW full-automatic stripping device. Background Art

[0002] OPGW (Optical Fiber Composite Overhead Ground Wire) is a type of optical fiber placed in the ground wire of an overhead high-voltage transmission line to form a fiber-optic communication network on the transmission line. This structural form has both ground wire and communication functions and is generally called OPGW optical cable.

[0003] During the splicing process of OPGW (overhead ground wire composite optical cable), the aluminum-clad steel wire on the outer ring needs to be cut off first. Currently, the aluminum-clad steel wire is cut with a grinding wheel, which has the following risks:

[0004] First, it requires high skills and energy from the operator. When using a grinding wheel for manual cutting, not only is it difficult to precisely control the cutting width and depth, but if the operator is not focused and the blade is pointed outward, there is a risk of accidentally injuring the optical fiber or the operator.

[0005] Second, during the later stage of cutting, the aluminum will adhere to the grinding wheel after being heated. Since the thermal conductivity of aluminum is higher than that of the grinding wheel, the grinding wheel will be overheated. When the temperature is higher than the tolerance temperature of the grinding wheel adhesive, the high-speed rotating grinding wheel may break and fly out, posing a personal safety hazard.

[0006] Although there are OPGW optical cable stripping devices on the market, most of these stripping devices are semi-automatic, still require manual control of the cutting depth, and have high requirements on the operators and the working environment.

[0036] It should be noted that: such as Figure 2 、 4As shown in the figure, a notch is provided on one side of the C-shaped gear 4, and the width of the notch is adapted to the width of the opening groove 2, facilitating the entry of the optical cable 11 into the clamping area and positioning it at the center of the C-shaped gear 4.

When the meshing position of one of the auxiliary gears 51 and the C-shaped gear 4 is at the notch position of the C-shaped gear 4, the other auxiliary gear 51 is always meshed with the C-shaped gear 4 and drives it, enabling the C-shaped gear 4 to still rotate driven by the auxiliary gear 51 in the state of missing teeth.

[0037] Among them, the slide table assembly 7 includes a U-shaped block 71 fixedly connected to the side wall of the control panel cover 62. A moving block 72 is arranged inside the U-shaped block 71. The side wall of the moving block 72 is fixedly connected to one side of the grinding wheel motor cover 8. Two slide rods 73 are fixedly arranged inside the U-shaped block 71. The slide rods 73 penetrate through the moving block 72 and are slidably connected to it.

One end of the first screw rod 74 extending out of the top of the U-shaped block 71 is fixedly connected to a feed knob 75.

[0038] It should be noted that: as Figure 5 shown, a scale 717 is provided on the side wall of the U-shaped block 71, and a pointer 718 is installed on the side wall of the moving block 72. Through the cooperation of the scale 717 and the pointer 718, the moving distance of the moving block 72 can be accurately controlled.

[0039] Among them, a locking disc 76 is fixedly connected to the first screw rod 74. The locking disc 76 is located between the feed knob 75 and the U-shaped block 71. An installation plate 77 is provided at a position on the top of the U-shaped block 71 close to the locking disc 76. A locking block 78 is arranged between the installation plate 77 and the locking disc 76. One side of the locking block 78 away from the locking disc 76 is fixedly connected to a pair of positioning rods 79. The other ends of the pair of positioning rods 79 penetrate through the side wall of the installation plate 77 and are fixedly connected to a baffle 710. The positioning rods 79 are slidably connected to the installation plate 77. An elastic member 711 is sleeved on the positioning rods 79. Both ends of the elastic member 711 are fixedly connected to the baffle 710 and the side wall of the U-shaped block 71 respectively. A second screw rod 712 is threadedly connected to the installation plate 77. One end of the second screw rod 712 is fixedly connected to a locking knob 713. The other end of the second screw rod 712 abuts against the side of the locking block 78 away from the locking disc 76.

[0040] Among them, a plurality of limiting grooves 714 are formed on the locking disc 76, and a plurality of embedding protrusions 715 are formed on the locking block 78. The embedding protrusions 715 are adapted to the sizes of the limiting grooves 714.

[0041] It should be noted that: as Figure 6As shown in the figure, a pair of anti-slip cushions 716 are symmetrically installed on the side wall of the locking block 78, and the pair of anti-slip cushions 716 are respectively located on both sides of a plurality of embedding protrusions 715. When the anti-slip cushions 716 are in contact with the locking disc 76, the limiting grooves 714 play an anti-slip role, thereby enhancing the friction between the anti-slip cushions 716 and the locking disc 76, and further cooperating with the embedding protrusions 715 to lock the first screw 74.

[0042] Wherein, an outer grinding wheel fixing cover 101 is sleeved outside the diamond cutting disc 10. The outer grinding wheel fixing cover 101 is fixedly connected to the side wall of the grinding wheel motor cover 8. And a through port 102 is arranged on one side of the outer grinding wheel fixing cover 101. Both sides of the outer wall of the outer grinding wheel fixing cover 101 are rotatably connected to an outer grinding wheel moving cover 103 through a shaft pin. One end of the outer grinding wheel moving cover 103 is fixedly connected to the outer grinding wheel fixing cover 101 through a bolt.

[0043] It should be noted that: as Figure 6 shown in the figure, corresponding threaded holes are provided at one end of the outer grinding wheel moving cover 103 and the outer wall of the outer grinding wheel fixing cover 101. In addition, compared with the traditional resin grinding wheel cutting disc, the diamond cutting disc 10 has characteristics such as sharpness and wear resistance, reduces the replacement frequency of the cutting disc, and is not prone to bursting during the cutting process, improving the use safety.

[0044] It should be noted that: as Figure 1 shown in the figure, a left housing cover 12 and a right housing cover 13 are respectively installed on both sides of the outer wall of the U-shaped fixing arm 1, and a rear housing cover 14 is installed on the inner wall of the U-shaped fixing arm 1, so as to protect the components and prevent the device from being damaged due to improper operations such as bumping.

[0045] Embodiment: as Figure 1-7 shown in the figure, in this embodiment, first, the optical cable 11 to be stripped is placed in the opening groove 2 provided on the U-shaped fixing arm 1, and the optical cable 11 is located between a pair of clamping jaws 31. At the same time, the optical cable 11 is located in the through port 102 of the outer grinding wheel fixing cover 101 and the notch 61 of the rotating fixing plate 6. Subsequently, the clamping electric rod 34 is started, so that the output end of the clamping electric rod 34 pulls the push plate 33 backward. When the push plate 33 moves backward, the L-shaped support arm 32 rotatably connected between the push plate 33 and the clamping jaws 31 rotates, so that the included angle between the pair of L-shaped support arms 32 decreases, thereby causing the pair of clamping jaws 31 to displace in the opposite direction, and further clamping the optical cable 11.

[0046] It can be seen from the above that: through the cooperation of the opening groove 2, the through port 102 and the notch 61, it is convenient for the optical cable 11 to enter and exit the clamping area. Cooperating with the clamping assembly 3, the clamping of the optical cable 11 can be quickly completed, indirectly improving the stripping speed of the optical cable 11.

[0047] After the optical cable 11 is clamped and fixed, the grinding wheel movable cover 103 is rotated to make the threaded hole at one end correspond to the threaded hole position of the outer wall of the grinding wheel fixed cover 101, and the grinding wheel movable cover 103 and the grinding wheel fixed cover 101 are fixed by bolts. At this time, the optical cable 11 and the diamond cutting blade 10 are both in the protective shell formed by the grinding wheel movable cover 103 and the grinding wheel fixed cover 101.

[0048] From the above, it can be seen that the split design of the grinding wheel movable cover 103 and the grinding wheel fixed cover 101 facilitates the optical cable 11 to enter the protective shell of the diamond cutting blade 10. The cooperation of the grinding wheel movable cover 103 and the grinding wheel fixed cover 101 can effectively block sparks, fragments or other potentially dangerous substances generated by cutting, reduce the risk of accidents, and also help maintain the cleanliness of the working environment, prevent waste generated by cutting from scattering and endangering personal safety, thereby improving the safety factor of equipment use.

[0049] Then the second drive motor 9 is started, so that the diamond cutting blade 10 fixedly connected to the output end of the second drive motor 9 rotates.

[0050] The staff turns the feed knob 75 so that the first screw 74 drives the moving block 72 to move downward along the slide rod 73, thereby driving the emery cutting blade 10 to move synchronously through the moving block 72. The emery cutting blade 10 contacts the optical cable 11 for cutting. The downward movement distance of the moving block 72 is accurately controlled through the cooperation of the scale 717 and the pointer 718, thereby accurately controlling the cutting depth of the emery cutting blade 10, thereby ensuring accurate cutting of the aluminum-clad steel wire outside the optical cable 11 without damaging the internal optical fiber of the optical cable 11.

[0051] Then, the locking knob 713 is rotated to move the second screw 712 threadedly connected to the mounting plate 77 toward the locking block 78, so that the front end of the second screw 712 abuts against the locking block 78, pushing the locking block 78 to move toward the locking plate 76 fixedly connected to the first screw 74 until the locking block 78 abuts against the locking plate 76, and the embedded protrusion 715 on the locking block 78 extends into the limiting groove 714, so that the locking plate 76 cannot rotate, thereby fixing the first screw 74, and thereby fixing the cutting depth of the diamond cutting blade 10.

[0052] When the cutting depth of the emery cutting disc 10 is fixed, start the first driving motor 55 to rotate the driving bevel gear 56, so that the driven bevel gear 54 is engaged by the driving bevel gear 56 to rotate the driven gear 53. Since the driven gear 53 is engaged with a pair of second auxiliary gears 52, and the pair of second auxiliary gears 52 are respectively engaged with a pair of first auxiliary gears 51, and the pair of first auxiliary gears 51 are also engaged with the C-shaped gear 4, when the driven gear 53 rotates, through the cooperation of the pair of second auxiliary gears 52 and the pair of first auxiliary gears 51, the C-shaped gear 4 rotatably connected to the inner wall of the C-shaped fixing arm 1 rotates. Since the optical cable 11 is located at the center of the C-shaped gear 4, when the C-shaped gear 4 rotates, the rotating fixing plate 6 drives the sliding table assembly 7 to rotate synchronously around the optical cable 11 as the axis. The sliding table assembly 7 drives the self-rotating emery cutting disc 10 to rotate synchronously around the optical cable 11 as the axis, so as to achieve the purpose of circumferentially cutting the optical cable 11, and further realize the effect of rapid wire stripping.

[0053] It should be noted that: the center of the C-shaped gear 4 is the same as the center of the clamped and fixed optical cable 11. Therefore, when the C-shaped gear 4 drives the emery cutting disc 10 to rotate, the emery cutting disc 10 also rotates with the same center, thereby improving the circumferential cutting effect of the optical cable 11.

[0054] As can be seen from the above: through the sliding table assembly 7 of the present device, the cutting depth of the emery cutting disc 10 can be accurately controlled, and through the transmission assembly 5, the emery cutting disc 10 can circumferentially cut the optical cable 11. While ensuring that the optical fiber inside the optical cable 11 is not damaged, the aluminum-clad steel wire outside the optical cable 11 is cut at high speed, improving the wire stripping efficiency of the optical cable 11, and at the same time avoiding the risk of personal injury caused by manually cutting the optical cable 11.

[0055] The embodiments of the present invention are given for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
