Description

Cable winding and storing device

Technical Field

The utility model relates to a cable winding storage device for to the protection when the longer cable winding tightens up or relaxs in the confined space like the antenna cabin.

Background

In confined spaces such as radar antenna cabins and the like, cable winders are often required to allow long power supply cables to be compactly folded or unwound so as not to occupy too much space. The existing cable winding device comprises a storage box, a winch, a rotating shaft and a servo motor, wherein the axis of the winch is fixed on the rotating shaft and is positioned in the storage box; the rotating shaft is rotatably supported on the side wall of the storage box, and one end of the rotating shaft penetrates through the storage box and is in transmission connection with an output shaft of the servo motor; one end of the storage box is provided with a cable through hole for a cable to pass through. The conventional cable winding device usually only considers the protection of cables except the device in a fixed state, for example, a cable groove or a cable trench is used for bundling and fixing, so that accident potential caused by stress deformation of the cables in the winding and unwinding processes in the winding device is not sufficiently considered, the problem of cable breakage and fracture caused by friction between the cables and the winding device in long-term operation often occurs, the use and maintenance are inconvenient, and the accident risk is difficult to avoid; in addition, the servo motor is not stopped timely after the cable is tightened or under the condition of clamping stagnation, so that the cable is easily damaged due to overlarge tension.

Disclosure of Invention

For overcoming the deficiencies in the prior art, the utility model provides a cable winding storage device.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a cable winding and accommodating device comprises an accommodating box, a winch, a rotating shaft and a servo motor, wherein the axis of the winch is fixed on the rotating shaft and is positioned in the accommodating box; the rotating shaft is rotatably supported on the side wall of the storage box, and one end of the rotating shaft penetrates through the storage box and is in transmission connection with an output shaft of the servo motor; one end of the storage box is provided with a cable through hole for a cable to pass through, and a damping transmission mechanism is arranged between one end of the rotating shaft and an output shaft of the servo motor.

The utility model has the advantages that: the cable can be rolled into the containing box at any time by utilizing the flexible transmission of the damping transmission mechanism, and when the external cable is completely contained or the cable is blocked, the cable is prevented from being damaged due to overlarge tension by utilizing the relative sliding of the damping transmission mechanism; and once the damping transmission mechanism slides relatively, the sensor sends a signal to stop the rotation of the servo motor, so that the servo motor is prevented from idling, and the electric power is saved; the structural design of the protective sleeve can prevent the cable from being scratched at the edge of the cable through hole in the retracting and releasing process, so that the reliability of the equipment is improved, the service life of the cable is prolonged, and the workload of equipment maintenance is reduced.

Detailed Description

Referring to fig. 1-4, the cable winding and storing device of the present invention comprises a storage box 3, a winch 1, a rotating shaft 2 and a servo motor 6, wherein the axis of the winch 1 is fixed on the rotating shaft 2 and is located in the storage box 3; this 2 rotation of pivot supports between the relative lateral wall of receiver 3, and receiver 3 is worn out to the one end of this pivot 2 to be connected with servo motor 6's output shaft transmission through damping drive mechanism 5. A cable through hole for the cable 8 to pass through is formed in one end of the storage box 3, a protective sleeve 4 for protecting the cable is disposed in the cable through hole, a circular notch (similar to a ball rack of a roller bearing) is formed in an outer port (a lower port in fig. 3) of the protective sleeve 4, and a ball 41 is disposed in each notch. It is also possible to provide both the inner and outer ports (upper and lower ports in fig. 4) of the sleeve 4 with a circular gap (similar to a ball cage of a roller bearing) in each of which a ball 41 is housed. Due to the design, friction and damage to the cable are greatly reduced.

The axial section of the protective sleeve 4 is hyperbolic or similar to the hyperbolic (arc bell mouth shape).

Referring to fig. 2, the damping transmission mechanism 5 includes a driving friction disc 51 and a driven friction disc 52, and the driving friction disc 51 is fixedly connected with an output shaft of the servo motor 6; the central hole of the driven friction disk 52 is slidably mounted on the shaft 2 through an axial sliding key (the driven friction disk 52 can only axially slide but cannot relatively rotate with the shaft 2), the front surface of the driven friction disk abuts against the driving friction disk, and the back surface of the driven friction disk is provided with a coil spring 53. The elastic force of the coil spring 53 makes the driven friction disc 52 and the driving friction disc 51 abut against each other and rub against each other (the friction force is designed according to the requirement), the friction force drives the driven friction disc 52 to rotate, when the cable 8 is tightened or stuck, the driving friction disc 51 and the driven friction disc 52 will slide relatively, and the cable is prevented from being pulled.

And a sensor 9 (a hall element or a photoelectric element can be used) between the driving friction disc 51 and the driven friction disc 52 for detecting the relative rotation of the driving friction disc 51 and the driven friction disc 52, when the driving friction disc 51 and the driven friction disc 52 slide relatively, the sensor 9 senses the rotation (one or more weeks, which can be set) of the sensing head 10 on the driven friction disc 52, and then sends a signal to control the servo motor 6 to stop.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and are not limitations on the protection scope of the present invention, but all the changes made by adopting the design principle of the present invention and performing non-creative work on this basis shall fall within the protection scope of the present invention.
