Description

Technical Field

[0001] The utility model relates to a pipeline laying device for communication engineering, belonging to the field of communication engineering. Background Art

[0002] The communication engineering major was established along with the development of China's communication industry. It was developed through the mutual penetration and complementation of wired and wireless communications, electronic technology, postal and telecommunications and other majors. In the establishment of communication engineering, a large number of cables are needed for data transmission, so pipeline laying devices are needed for laying cables.

[0003] For communication cables, cables with smaller wire diameters are generally paid out directly through cable pay-out racks or cable pay-out reels. However, large cables with thicker wire diameters are required for long-distance data transmission. Large cables are not only heavy, but also require lifting equipment or forklifts to move the pay-out reel from the winding device, which not only consumes a lot of manpower and material resources, but also reduces the pay-out efficiency and cannot be used in different occasions.

[0004] Chinese utility model patent CN202222316774.8 provides a cable pay-off vehicle; the cable pay-off vehicle combines a traditional horizontal cable pay-off frame with a trolley for easy movement; and is equipped with a gas spring to allow the horizontal cable pay-off frame to be transformed into a vertical pay-off platform, which is suitable for more usage environments.

[0005] However, when the horizontal cable pay-off stand is transformed into a vertical pay-off platform, the more cables are wound on the pay-off platform, the greater the gravity will be. Excessive cable gravity will cause the rollers between the fixed seat and the rotating seat to separate, affecting the rotation of the rotating seat. Utility Model Content

[0006] The purpose of the utility model is to provide a pipeline laying device for communication engineering, which can effectively solve the above-mentioned problems.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] It comprises a horizontal pay-off platform; the horizontal pay-off platform comprises an annular fixed seat, an annular rotating seat is arranged at the upper end of the fixed seat, a rotating shaft is arranged in the middle of the rotating seat; and a roller assembly is also arranged between the rotating seat and the fixed seat; the roller assembly comprises an annular mounting groove arranged on the upper end surface of the fixed seat, a mounting strip fixed on the lower end surface of the rotating seat, a mounting plate is arranged at the lower end of the mounting strip, and rollers are arranged on the upper and lower end surfaces of the mounting plate; and a retaining ring is arranged at the notch position of the mounting groove.

[0009] Furthermore: the mounting bar is divided into a rigid column fixed on the lower end surface of the rotating seat and a connecting shaft fixed on the lower end of the rigid column, and the connecting shaft is fixedly connected to the mounting plate.

[0010] Further: a ring groove is arranged in the middle of the retaining ring for the connecting shaft to pass through.

[0011] Furthermore: there are three roller assemblies, which are evenly distributed between the rotating seat and the fixed seat; and each roller assembly is equipped with four rollers; the rollers are grouped in groups of two and arranged on the upper and lower end surfaces of the mounting plate.

[0012] Furthermore: a convex ring is arranged on the lower end surface of the retaining ring, and a side surface of the convex ring is smooth with the groove surface of the annular groove.

[0013] Further: the roller includes two symmetrical side plates, a rotating shaft arranged between the side plates, and a wheel key-connected to the rotating shaft.

[0014] Furthermore: the outer surface of the wheel is paved with a rubber layer.

[0015] The beneficial effects are:

[0016] First, an annular mounting groove is arranged on the upper end surface of the fixed seat, and rollers are arranged on the upper and lower end surfaces of the mounting plate. When the retaining roller assembly is placed in the mounting groove, the roller at the lower end of the mounting plate will contact the bottom surface of the mounting groove; when the horizontal pay-off table is used normally, the roller can be used to rotate the rotating seat to achieve the operation of pay-off and take-up;

[0017] At the same time, the device is provided with a retaining ring at the notch position of the mounting groove, and the retaining ring is pressed on the roller located on the upper end surface of the mounting plate; when the horizontal pay-off platform is transformed into a vertical pay-off platform, the wound cable has a large gravity, causing the center of gravity of the rotating seat to shift. At this time, the roller located on the upper end surface of the mounting plate presses on the retaining ring, which can prevent the rotating seat from tilting, so that the pay-off and take-up operations can run stably.
