Description

Technical Field

[0001] The present invention relates to the technical field of communication engineering, and in particular to a communication cable retracting and releasing device for arranging cables for big data communication engineering. Background Art

[0002] Communication engineering, also known as telecommunications engineering, focuses on the principles and applications of information transmission and signal processing in the communication process; the communication engineering major mainly studies the generation of signals, transmission, exchange and processing of information, as well as theoretical and engineering application issues in computer communication, digital communication, satellite communication, fiber optic communication, cellular communication, personal communication, stratospheric communication, multimedia technology, information superhighway, digital program-controlled switching, etc.; communication engineering construction refers to organized activities carried out by specific personnel in accordance with relevant standards for the purpose of building communication networks and realizing information transmission; and communication cables are the main transmission carriers in the construction process. They are composed of multiple mutually insulated wires or conductors to form a cable core, with a sealed sheath on the outside, and some are also equipped with an outer sheath outside the sheath. There are various laying methods such as overhead, direct burial, pipeline and underwater; communication cables have a wide transmission bandwidth, large communication capacity, and are less affected by external interference, but are not easy to repair. They can transmit telephone, telegraph, data and images.

[0003] Communication cables can be divided into the following categories according to their cable form: (1) Single conductor: This refers to the most primitive communication cable, a single conductor loop with the earth as the tropism; (2) Symmetrical cable: A loop is formed by two conductors that are exactly the same under ideal conditions; (3) Coaxial cable: A loop is formed by two inner and outer conductors on the same axis, with the outer conductor surrounding the inner conductor and both insulated.

[0004] However, the existing processing equipment has the following deficiencies:

[0005] In daily use, it is found that communication cable retraction devices such as CN109650191A are mostly used to fix the position of the device body using self-locking rollers. During the process of the device retracting and releasing the cables, the cables will generate a certain force, so that the device fixed with the self-locking rollers will be pulled by the cables and displaced, causing the device to easily tip over during actual use.

[0006] Therefore, we propose a communication cable retracting device for big data communication engineering wiring to solve the above problems. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention sets a stabilizing mechanism. When the cable is recovered, the switch of the servo motor is turned to the reverse position. The servo motor is energized to drive the wire roller to rotate in the opposite direction. The wire roller recovers the released cable during the rotation. When the equipment moves to the predetermined working position, the switch of the hydraulic cylinder is turned on, the hydraulic cylinder is energized to work, and the hydraulic cylinder pushes the damping plate. The damping plate is displaced under the guidance of the guide column. The damping plate contacts the ground during the movement and provides support for the frame. When the work is completed and the equipment is recovered, the switch of the hydraulic cylinder is turned off. The hydraulic cylinder gradually pulls the damping plate to its original position. The damping plate leaves the ground, the equipment loses the resistance of the damping plate, and then the equipment can be recovered. By setting the stabilizing mechanism, the friction between the equipment and the ground is enhanced, thereby avoiding the problem of the equipment being pulled and tipped over by the force when retracting and releasing the cable, and further improving the stability of the equipment.

[0022] 2. The present invention sets a blocking mechanism. After the assembly of the stabilizing mechanism is completed, the positioning frame is pushed, and the positioning frame pushes the protective sleeve. The protective sleeve is pushed and inserted into the limit frame. At the same time, the protective sleeve pushes the sealing ring to the surface of the distribution box. Then the fixing bolt is inserted into the positioning frame, and the fixing bolt is rotated. The fixing bolt is gradually screwed into the threaded groove and the position of the positioning frame is fixed. The positioning frame fixes the position of the protective sleeve under the action of the fixing bolt, and then the installation operation of the blocking mechanism is completed. By setting the blocking mechanism, the sealing of the connection between the stabilizing mechanism and the distribution box is improved, thereby reducing the probability of the medium penetrating into the distribution box and further improving the safety of the connection part.

[0023] 3. The present invention provides a bearing mechanism. When assembling the stabilizing mechanism, the wire is placed on the limit base, and then the U-shaped frame is toggled. During the movement, the U-shaped frame contacts the pin, and the pin is pushed by the U-shaped frame. The pin squeezes the reset spring, and the reset spring is squeezed and deformed. The pin loses the constraint of the reset spring and slides into the slide groove. The U-shaped frame loses the constraint of the pin and buckles to the surface of the limit base. At the same time, the pin loses the pressure applied by the U-shaped frame, and the reset spring rebounds without the pressure of the pin. The pin is pushed to reset and insert into the jack, and the position of the U-shaped frame is fixed. The operation of fixing the wire position is then completed. By providing the bearing mechanism, the position of the wire can be limited, thereby reducing the probability of the wire being entangled during use and improving the service life of the wire.
