Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable, in particular to a kind of optical fiber composite low-voltage cable winding equipment. BACKGROUND

[0002] Optical fiber composite low-voltage cable is a kind of cable that combines optical fiber and cable together, with double advantages. Optical fiber composite low-voltage cable can transmit telecommunication signals and optical signals, so it has a wide range of applications in many application scenarios. The cable structure is complex, and it is currently a high-end cable product. In order to facilitate transportation and storage, a corresponding winding device is needed during the production process of optical fiber composite low-voltage cable.

[0003] For example, the Chinese patent with publication number "CN218708101U" discloses a "cable winding equipment", the main structure of which includes a base plate, two bearing plates fixedly connected to the top rear side of the base plate, a first spring fixedly connected to the opposite side of the inner cavity of each bearing plate, a rebound column fixedly connected to the opposite side of each first spring, a barrier body fixedly connected to the opposite side of each rebound column, a support plate fixedly connected to the top of the inner cavity of each bearing plate, a rotating wheel movably connected between the opposite sides of the two support plates, a first motor fixedly connected to the right side of the rotating wheel, and a clamping mechanism fixedly connected to the front side of the top of the base plate. The cable winding equipment solves the problem of inconvenient clamping and collection of the existing cable winding equipment by the cooperation of the bearing plate, the first spring, the rebound column, the barrier body, the support plate, the rotating wheel, the first motor and the clamping mechanism.

[0004] However, the traction force of the winding wheel on the cable winding part cannot be controlled when the winding wheel is winding the cable, which can easily cause the wire body to break. Optical fiber composite low-voltage cable has a built-in sensing monitoring optical fiber. As we all know, optical fiber is brittle and has no ductility (all cable cores made of copper, aluminum and other metal materials have ductility), and the breaking force is much smaller than that of ordinary cable. Therefore, the quality of optical fiber composite low-voltage cable cannot be guaranteed by using conventional cable winding equipment. It is necessary to invent a device that can feedback the winding tension and adjust it synchronously. SUMMARY

[0005] TECHNICAL PROBLEM SOLVED In view of the shortcomings of the prior art, the present application provides a kind of optical fiber composite low-voltage cable winding equipment. The linkage structure of the controllable contact pressure formed on the inner surface of the winding wheel by the stress and deformation can control the maximum traction strength of the winding wheel on the cable wire when the winding wheel is winding the cable wire, thereby protecting the wire body and preventing the wire body from breaking due to excessive traction. The above technical problems are solved.

[0006] Technical Solution To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a fiber-optic composite low-voltage cable winding device, comprising a bottom mounting base and a winding wheel with a hollow structure in the center, wherein three component fixing bases in the same straight line are installed on the upper surface of the bottom mounting base, wherein the tops of two adjacent component fixing bases are respectively fixed with a main shaft sleeve, and the top of the other component fixing base is fixed with a driving motor, and the periphery of the two end surfaces of the winding wheel are respectively provided with a hollow ring structure of an integrated structure, and the outer circumferential surfaces of the two hollow ring structures are installed in the sleeve hole of the main shaft sleeve through bearings, and the end of the motor main shaft in the driving motor is located inside the hollow structure of the hollow ring structure and the winding wheel, and the end of the motor main shaft is installed with a linkage structure that deforms after being subjected to force, and the linkage structure can form a controllable resistance pressure on the inner surface of the winding wheel.

[0007] Through the above technical solution: a linkage structure is used to form a controllable resistance pressure on the inner surface of the winding wheel after being subjected to force and deforming, so that a certain degree of resistance effect is formed on the inner surface of the winding wheel. When driven by the driving motor, this resistance effect will generate sliding friction with the inner surface of the winding wheel. This sliding friction makes the winding wheel tend to rotate. By making the extrusion force less than the torque strength that makes the winding wheel rotate, the wire body wound in the winding wheel can be prevented from breaking due to excessive traction force when pulling the wire body.

[0008] Preferably, the linkage structure includes a first circular plate body and a second circular plate body, the first circular plate body and the second circular plate body are fixedly connected at the center of opposite end faces by a main limit rod, the first circular plate body and the second circular plate body are sleeved with a cylindrical airbag at the opposite ends, and the cylindrical airbag is sleeved on the periphery of the first circular plate body and the second circular plate body and fixed by a clamping ring, the hollow structure of the cylindrical airbag forms a gas storage chamber, the center of the other end of the first circular plate body is provided with an inward-concave first rod body mounting groove, the interior of the second circular plate body is provided with a first component mounting hole and a first air hole communicating with its two end faces, the interior of the first component mounting hole and the first air hole are respectively installed with an air pressure control mechanism and a first gas valve for controlling the maximum air pressure inside the gas storage chamber, and the interior of the first rod body mounting groove is fixedly installed with the end structure of the motor main shaft.

[0009] Through the above technical solution: by injecting high-pressure gas, the cylindrical airbag can be expanded outward, and then the cylindrical airbag is made to contact the inner surface of the winding wheel, generating the necessary friction function.

[0010] The cam is secured to the outside of the casing and is secured to a location where the cam is secured, and the cam is secured to the outside of the casing and is secured to a location where the cam is secured.

[0011] Through the above technical solution: by injecting high-pressure air into the interior of the cylindrical hollow cavity, the high-pressure air pushes the fourth circular plate to move to one side, thereby squeezing the cylindrical rubber body, and the side surface of the cylindrical rubber body expands outward, thereby causing the cylindrical rubber body to contact the inner surface of the winding wheel, generating the necessary friction function.

[0012] Preferably, the structural radius of the first circular plate body and the second circular plate body is smaller than the structural radius of the hollow structure in the winding wheel.

[0013] Preferably, the structural radius of the third circular plate, the fourth circular plate and the columnar rubber body when not squeezed is smaller than the structural radius of the hollow structure in the winding wheel, and the structural radius of the columnar rubber body when not squeezed is larger than the structural radius of the third circular plate and the fourth circular plate.

[0015] Through the above technical solution: the maximum pressure value of the high-pressure gas inside the equipment can be controlled. Once this value is exceeded, the secondary piston plate moves to connect the internal space and the excess gas can be discharged in time, thereby effectively preventing the occurrence of wire breakage caused by excessive traction force.

[0016] Preferably, the distance between the secondary gas flow hole and the primary gas flow hole is greater than zero.

[0017] Compared with the prior art, the present invention provides a fiber-optic composite low-voltage cable winding device, which has the following beneficial effects: 1. The fiber-optic composite low-voltage cable reeling device utilizes a linkage structure that forms a controllable resistance pressure on the inner surface of the reel after being subjected to force and deforming.
