[0002] Optical cable construction cannot do without an optical cable erection machine, and the bundling wire feeding device is an important component of the optical cable erection machine. The bundling wire feeding device of the original power optical cable erection machine has the following defects after actual application tests. First, there is no safety stop on the wire supply reel. When the erection machine operates at a height of more than 4 meters, the long-term rotation of the rotating cylinder causes the wire feeding device to be under the action of centrifugal force, and it is very difficult to ensure that the installed components do not fall off. Once a component falls, it will cause damage and even serious accidents such as injury to ground operators. Second, when the bundling wire is pulled and rotated on the bundling wire supply reel, there is no damping component. Even if there is an individual damping component, its damping force cannot be adjusted, so that the bundling wire has no tension or the tension cannot be adjusted, and the bundling result is either too tight or too loose, seriously affecting the quality and safety of optical cable construction. Therefore, it is very necessary to develop a bundling wire feeding device for a power optical cable erection machine. Summary of the Invention

[0026] The following further details the implementation method of the bundling wire feeding device of this power optical cable erection machine in conjunction with the attached drawings (see Figures 1 to 18 ):

[0027] The bundling wire feeding device of this power optical cable erection machine is composed of a base mounting plate 1, a base shaft 2, a wire feeding disc body 3, a wire feeding disc cover 4, a bundling wire 5, a weight reduction hole 6, a pressure retaining cover 7, a male and female clamping position 8, a safety stopper 9, a damping part 10, a base shaft threaded hole 11, a movable fixing device 12, and a rotating cylinder 13; a screw rod is integrally made on the pressure retaining cover 7, and the diameter of the screw rod of the pressure retaining cover 7 is smaller than the diameter of the base shaft threaded hole 11; one end of the base mounting plate 1, the safety stopper 9, and the movable fixing device 12 are installed on the rotating cylinder 13.

[0028] The base mounting plate 1 is mounted with a base shaft 2 by welding or riveting or fastening screws or concave holes + fastening screws. If the base shaft 2 and the base mounting plate 1 are assembled by concave holes + fastening screws, the base mounting plate 1 and the base shaft 2 are concave-convex connection structures. A concave hole is made on the base mounting plate 1, and the flat head or round head of the fastening screw is fixed in the concave hole without exceeding the plane of the base mounting plate 1. The base mounting plate 1 is fixedly mounted with the base shaft 2 by the fastening screws. Reinforced bends are made on both sides of the base mounting plate 1. A base shaft threaded hole 11 for screwing the screw of the pressure blocking cover 7 is made inside the other end of the base shaft 2; the wire supply reel body 3 is sleeved on the base shaft 2, and the screw of the pressure blocking cover 7 is screwed into the base shaft threaded hole 11 to assemble and press the wire supply reel body 3, and the pressure blocking force is adjusted by the depth of the screw of the pressure blocking cover 7 screwed into the base shaft threaded hole 12. A damping member 10 is installed between the wire supply drum body 3 and the base mounting plate 1 or between the wire supply drum body 3 and the pressure stop cover 7; or damping members 10 are installed between the wire supply drum body 3 and the base mounting plate 1 and between the wire supply drum body 3 and the pressure stop cover 7. The wire supply drum body 3 and the wire supply drum cover 4 are assembled by screwing in and out of the screw thread, and the wire supply drum body 3 and the wire supply drum cover 4 form a wire supply drum;

[0029] After the supply reel cover 4 is unscrewed and removed, the binding wire 5 is loaded on the supply reel body 3 and screwed in to cover the supply reel cover 4. A plurality of male and female positions 8 are made on the pressure-blocking cover 7, and the safety stopper 9 and the pressure-blocking cover 7 are mutually locked and positioned through the male and female positions 8. When the damping force is adjusted by the pressure-blocking cover 7, the pressure-blocking cover 7 can be mutually locked through the cooperation of the male and female positions 8 and at least one male and female position 8 of the safety stopper 9 when the pressure-blocking cover 7 is rotated to each corresponding position. The male and female positions 8 can be holes, pins, or polygonal concave, convex, or grooves, or keys, that is, holes and pins cooperate, concave and convex cooperate, and grooves and keys cooperate. As long as the technical means can achieve mutual locking and prevent the pressure-blocking cover 7 from rotating without authorization, they can be adopted. In addition, it is also possible to realize the locking control of the pressure-blocking cover 7 by setting a movable key pin on the threaded hole 11 of the base shaft and the screw of the pressure-blocking cover 7.

[0030] The wire supply drum body 3 and the wire supply drum cover 4 are respectively provided with weight-reducing holes 6, and the wire supply drum cover 4 is also provided with a spare hole 14. The base mounting plate 1, one end of the safety stopper 9, and the movable fixing device 12 are fixedly mounted on the rotating drum 13, and the other end of the safety stopper 9 is movably connected to the rotating drum 13 through the movable fixing device 12. The movable fixing device 12 includes a card lock, a touch lock, a rotating lock, a movable latch, and the like. The movable fixing device 12 controls the opening or closing of the safety stopper 9, and is convenient for adjusting the pressure stopper cover 7 and loading the binding wire 5.

[0031] The functions of the various parts of the bundling and supplying device of the power optical cable erecting machine are as follows:

[0032] The base mounting plate 1 is used to mount and support the base shaft 2 and is reliably mounted and connected to the rotating cylinder 13 .

[0033] The base shaft 2 is used to fit the wire supply drum body 3 and the damping member 10 , and to install the pressure stop cover 7 .

[0034] The wire supply reel body 3 is used for loading the binding wire 5 , and together with the wire supply reel cover 4 , the wire supply reel rotates as a whole to release the binding wire 5 .

[0035] The wire supply drum cover 4 is used to compress the loaded binding wire 5.

[0036] The binding wire 5 is used for binding the optical cables.

[0037] The weight-reducing hole 6 is used to reduce the weight of the entire wire supply drum and can also serve as an observation hole.

[0038] The pressure-blocking cover 7 is used to press and block the wire supply drum body 3, and can also adjust the damping force when the wire supply drum body 3 rotates, and can be mutually locked and positioned with the safety stopper 9 through the male and female clamping positions 8.

[0039] The male and female clamping positions 8 are used to clamp the pressure blocking cover 7 so that the pressure blocking cover 7 does not change when it is at the most suitable damping force position.

[0040] The screw of the pressure stop cover 7 is used to install the pressure stop cover 7 and adjust the damping force by screwing in and out of the base shaft threaded hole 11.

[0041] The base shaft threaded hole 11 is used to assemble the pressure-blocking cover 7 and cooperate with the pressure-blocking cover 7 to adjust the damping force.

[0042] The safety stopper 9 is used to prevent the wire supply reel and related components from falling from a high altitude, and is clamped and positioned with the pressure stopper cover 7, while further stabilizing the base shaft 2.

[0043] The damping member 10 is used to generate a damping force when the wire supply drum is pulled and rotated by the binding wire 5, so that the binding wire 5 has tension and the binding effect is moderately tight and loose.

[0044] The movable fixing device 12 is used to movably mount the safety stopper 9 on the rotating cylinder 13, so as to facilitate opening or firmly closing the safety stopper 9.

[0045] The rotating cylinder 13 is used to install the base mounting plate 1, the safety stopper 9, and the movable fixing device 12, and drive them to rotate together.

[0046] The spare hole 14 is used to install a temporary handle or a toggle member when needed.

[0047] The assembly operation process of the bundled supply device of the power optical cable erecting machine is as follows:

[0048] First, install the base shaft 2 on the base mounting plate 1 so that the base shaft 2 and the base mounting plate 1 form an integral body, and then install the base mounting plate 1 together with the base shaft 2 on the rotating cylinder 13. Then, sequentially sleeved the damping member 10 and the wire supply reel body 3 on the base shaft 2. After sleeving, the wire supply reel body 3 should be able to rotate smoothly on the base shaft 2. Then, if a damping member 10 is installed between the wire supply reel body 3 and the pressing cover 7, the depth of screwing the screw of the pressing cover 7 into the threaded hole 11 of the base shaft can press against the wire supply reel body 3 and the damping member 10. Fill the pre-made bundled wire 5 onto the wire supply reel body 3. After filling the bundled wire 5, finally, screw the wire supply reel cover 4 onto the wire supply reel body 3 through thread engagement to press and tighten the bundled wire 5. The safety stop 9 and the movable fixing device 12 are correspondingly installed on the barrel wall of the rotating cylinder 13. One end of the safety stop 9 is fixedly installed on the rotating cylinder 13, and the other end of the safety stop 9 is movably installed and connected to the rotating cylinder 13 through the movable fixing device 12, which is convenient for flexibly opening or closing the safety stop 9 without affecting other operations.

[0049] For the bundled wire supply device of the power optical cable erection machine of the present invention, the wire supply reel body 3 and the wire supply reel cover 4 are designed as two parts that are thread-engaged. It is not only convenient to load the bundled wire 5, with high operation efficiency, but also wire coils of bundled wires 5 with different sizes within a certain range can be normally loaded and used. After the above installation is completed, rotate the whole wire supply reel or pull the end of the bundled wire 5 to feel whether the damping force and the tension of the bundled wire 5 are appropriate. If the damping force is small, tighten the pressing cover 7. If the damping force is large, loosen the pressing cover 7. After adjusting the damping force appropriately, engage the male and female positions 8 corresponding to the safety stop 9 with the pressing cover 7. In this way, each rotation of the pressing cover 7 can be reliably engaged with at least one male and female position 8 made corresponding to the safety stop 9. The number of rotation gears of the pressing cover 7 can also be designed according to actual needs. At the same time, the movable end of the safety stop 9 is reliably locked and connected to the rotating cylinder 13 through the movable fixing device 12, so that the base mounting plate 1, the wire supply reel body 3, the wire supply reel cover 4, and the base shaft 2 will not become loose and fall due to the long-term action of the centrifugal force generated by the rotation of the rotating cylinder 13 during the high-altitude operation of the erection machine, preventing serious accidents such as component damage and injury to ground operation personnel. The setting of the safety stop 9 further stabilizes the base shaft 2 and also makes the pressing cover 7 unable to rotate randomly. The opening or reliable closing of the safety stop 9 can be controlled through the movable fixing device 12.

[0050] The above is only the preferred embodiment of the present invention. The above examples do not impose any formal restrictions on the essence of the present invention. Any simple modification or deformation made by those of ordinary skill in the technical field to the above specific implementation manners according to the technical essence of the present invention after reading this specification, and any equivalent embodiments that may be changed or modified by using the above-disclosed technical content into equivalent variations still fall within the scope of the technical solution of the present invention without departing from the essence and scope of the present invention.
