Description

Technical Field

[0001] The utility model relates to the technical field of communication optical cable pay-out, in particular to a communication optical cable anti-destruction pay-out device. Background Art

[0002] With the advent of the information age, the development of various industries in my country is closely related to communication technology. Therefore, both enterprises and people have high requirements for communication levels. The development speed of the communication industry is also very rapid. The quality of communication technology is directly related to the current communication optical cable lines.

[0003] At present, when laying optical cables, a pay-off device is needed. For example, the patent with application number CN217263795U discloses an optical cable pay-off device for communication construction, in which the rolled optical cable is placed on a turntable, and the turntable can be rotated on the base. The pay-off process can be realized after the turntable rotates, which solves the problem of convenient pay-off. However, it still has some shortcomings in the actual environment. For example, when laying optical cables, the turntable cannot move, and the optical cable needs to be dragged on the ground for pay-off. The friction between the optical cable and the ground can easily cause wear on the surface of the optical cable. When the pay-off stops, the optical cable drum is prone to pay-off due to inertia. In addition, since a lifting device is required to place the optical cable drum on the pay-off vehicle, and then the axis and the optical cable drum are manually aligned and installed, this installation method has safety hazards. It is easy for the hoisted optical cable drum to hit the workers. In addition, the installation time is long, which is time-consuming and labor-intensive. Utility Model Content

The pinch wheel adjustment bolt 342 is arranged perpendicular to the rotation rod 31 and is threadedly connected to the lower portion of the mounting bracket 1. The pinch wheel mounting bracket is threadedly connected to the tail end of the pinch wheel adjustment bolt 342. The pinch wheel 341 is arranged axially parallel to the rotation rod 31 and is rotatably connected to the pinch wheel mounting bracket, with its rolling surface corresponding to the pay-off wheel 33 to form a cable clamping channel. The pinch wheel adjustment bolt 342 can be used to adjust the distance between the pinch wheel 341 and the pay-off wheel 33, facilitating cable clamping and enabling the clamping of cables of different sizes.

[0054] In one embodiment, the lifting assembly 4 includes a first threaded rod 41, multiple guide rods 42, and a U-shaped support frame 43. The first threaded rod 41 is arranged along the height direction of the mounting frame 1 and is rotatably connected thereto.

The second threaded rod 51 is a counter-threaded rod arranged parallel to the rotation rod 31, with its ends rotatably connected to opposite side walls of the U-shaped support frame 43. A sliding groove 431 arranged parallel to the second threaded rod 51 is defined on the inner wall of the closed end of the U-shaped support frame 43. The two clamping arms 52 are arranged perpendicular to the second threaded rod 51 and are respectively threadedly connected to the ends of the second threaded rod 51.

[0056] In one embodiment, each clamping arm 52 comprises a sleeve 521, a slide rod 522, and a positioning assembly 523. The sleeve 521 is arranged perpendicular to and threadedly connected to the second threaded rod 51. A slider is fixed to one end of the sleeve, and a positioning hole 5211 is defined in the sidewall of the other end. The slide rod 522 is coaxially arranged with the sleeve 521, and one end of the slide rod is slidably inserted into the other end of the sleeve 521. A plurality of adjustment holes 5221 are defined in the sidewall of the slide rod 522 along its axial direction. The optical cable drum insertion positioning member 53 is rotatably mounted on the other end of the slide rod 522. The positioning end of the positioning assembly 523 can pass through the positioning hole 5211 and be inserted into the adjustment hole 5221. By changing the length of the slide rod 522 inserted into the sleeve 521, the length of the clamping arm 52 can be adjusted to clamp optical cable drums of different sizes.

[0057] In a specific embodiment, the positioning assembly 523 includes a fixed cover 5231, a positioning pin 5232, a limit block 5233, a limit ring 5234 and a spring 5235. The fixed cover 5231 is fixed on the side wall of the sleeve 521 at the corresponding positioning hole 5211. The positioning pin 5232 is placed in the fixed cover 5231, one end of which is the positioning end and the positioning end can pass through the positioning hole 5211 and be inserted into the adjustment hole 5221, and the other end passes through the side wall of the fixed cover 5231 away from the sleeve 521 and is fixedly connected to the limit block 5233.

[0058] In one embodiment, the cable drum insert positioning member 53 is a tapered block axially perpendicular to the slide bar 522. Its larger end is pivotally mounted on the end of the slide bar 522 distal from the sleeve 521, while its smaller end is inserted into the center hole of the cable drum. Anti-slip grooves are provided on its tapered surface. The tapered structure facilitates insertion of the cable drum insert positioning member 53 into the center hole of the cable drum, facilitating quick and easy installation. The anti-slip grooves also enhance the secure connection to the cable drum.

[0059] In a specific embodiment, a handle 6 is installed on the upper portion of the mounting frame 1. By pushing the handle 6, under the action of the running wheels 2, the mounting frame 1 can be easily driven to move the optical cable drum.

[0060] In the present invention, the mounting frame 1 is moved to either side of the cable drum, the positioning pin 5232 is pulled to disengage the positioning hole 5221, and the position limit on the slide rod 522 is released. The length of the clamping arm 52 is adjusted so that the tapered block aligns with the center hole of the cable drum. This allows cable drums of varying diameters to be secured. The positioning pin 5232 is then released, and the spring 5235 allows the positioning pin 5232 to be inserted into the corresponding adjustment hole 5221, completing the adjustment of the length of the clamping arm 52. The handle is then rotated, driving the second threaded rod 51 to rotate, causing the two clamping arms 52 to drive the two tapered blocks into the center hole of the cable drum, thereby clamping and securing the cable drum. The handwheel is then rotated, driving the first threaded rod 41 to rotate, raising the cable drum. After the cable drum is raised, the free end of the optical cable is overlapped in the annular guide groove of the pay-off wheel 33. The pressure wheel adjustment bolt 342 is then tightened, driving the pressure wheel 341 to clamp and secure the cable. The staff drives the mounting frame 1 to move through the walking wheel 2 through the handle 6, and at the same time the pay-off wheel 33 rotates to pull out the optical cable, thereby achieving the purpose of paying out the cable while moving, which can prevent the optical cable from being damaged by friction with the ground and prevent the phenomenon of paying out too much cable.
