In order to realize the automatic operation of the cable winding device, a controller is also arranged, and a winding motor 3205 is electrically connected with the controller; the controller is used for controlling the rotating speed of the cable winding motor 3205 according to the collected moving speed of the cable winding device, so that the speed of releasing or winding the cable by the cable winding component 32 is matched with the moving speed of the cable winding device.

It should be noted that the controller includes a winding controller and a mobile work machine controller 20 that loads the cable winding device. The coil controller is integrated in the cable coil control box 33, and the cable arm driving motor 3101, the first linear driver 3114 and the third linear driver 3108 are all electrically connected with the coil controller. The reciprocating drive motor 3207 is electrically connected to the mobile work machine controller 20, and may be either linked to the spooling motor 3205 or operated independently to adjust the position of the fairlead 3116.

The lay-up controller may be integrated with the mobile machine controller 20 or may be separate; in the present embodiment, the mobile work machine controller 20 is provided on the mobile work machine so as to manipulate the mobile work machine.

The electrical connection between the controller and the actuator includes the connection with the cable arm driving motor 3101, the first linear driver 3114 and the third linear driver 3108, and may be connected via wireless communication, such as bluetooth, infrared, wifi, etc., or wired via cable for command reception and/or data feedback.

The reeling control cabinet 33 may be arranged directly to the mobile working machine or may be fixed to a frame 34 on which the cable reeling assembly 32 is mounted. The cable laying assembly 32 is generally arranged in front of the cable path control assembly 31 along the advancing direction of the mobile working machine, the cable laying control box 33 can be arranged according to the layout of the mobile working machine, and is generally fixed on a rack 34 for mounting the cable laying assembly 32, and the control box control interface faces the outer side of the vehicle, so that manual control is facilitated.

In order to facilitate monitoring of the cable laying and winding path, a cable laying and winding path monitoring assembly is further provided in the present embodiment, and includes all sensors and circuits thereof, etc. for normal operation of the cable laying device. The cable laying and reeling path monitoring assembly generally includes a cable arm drive motor 3101 angle sensor, a laying motor 3205 rotational speed sensor (or encoder), a reciprocating drive motor 3207 rotational speed sensor, a third linear drive 3108 length sensor, a first linear drive 3114 length sensor, a slip ring case 3202 temperature and humidity sensor, a cable laying control case 33 temperature and humidity sensor, a cable arranger 3206 position sensor, cable full and empty sensors, a mobile work machine travel speed sensor, a mobile work machine steering radius sensor, and a mobile work machine position sensor, etc.

According to the cable winding device provided by the embodiment, the working principle of the cable winding device is as follows:

the cable laying and rolling device works synchronously through two independent processes, namely the cable laying and rolling speed is controlled by the cable laying and rolling component 32, and the cable laying path is controlled by the cable path control component 31.

The cable path control assembly 31 controls the cable laying path operations as follows:

after the mobile working machine controller 20 processes the mobile working machine position information and the cable arranger 3206 position information, it gives an instruction to the cable arm drive motor 3101, the third linear actuator 3108 and the first linear actuator 3114;

the cable support arm driving motor 3101 receives the instruction to start rotating, and drives the rotating shaft 3103 to rotate through the cable support arm driving mechanism 3102 to reach the specified angle and stop;

the third linear driver 3108 receives the instruction to start stretching, and since one end is fixed on the rotating shaft 3103 and can not move, the other end pushes the cross bar 3118 of the cable support arm 3106 to slide, and the distance from the cable guide 3116 to the rotating shaft 3103 reaches a designated value and then stops;

the length of the first linear driver 3114 is instructed to start stretching, and since one end of the first linear driver is fixed on the cable support arm 3106, the cross bar cannot move, and the other end of the first linear driver pushes the cable guide frame 3116 to slide, the first linear driver stops after reaching the specified length; so as to adjust the laying path of the cable according to the moving path of the mobile working machine loaded with the cable laying device.

The cable laying assembly 32 controls cable laying and take-up speed operations as follows:

the mobile working machine controller 20 processes the speed information of the mobile working machine, the turning radius information of the mobile working machine, the angle information of the cable arm driving motor 3101, the length information of the third linear driver 3108 and the length information of the first linear driver 3114, and sends instructions to the winding motor 3205 and the reciprocating driving motor 3207 through the winding controller;

upon receiving a command to start rotating at a predetermined speed, the winding motor 3205 drives the reel assembly 3201 and the slip ring housing 3202 to rotate around the spindle via the reel drive gear 3204, and the cable starts to be wound or wound at a predetermined speed.

The reciprocating driving motor 3207 receives an instruction to start rotating according to a designated rotating speed, drives the cable arranger 3206 to reciprocate, and when the moving speed of the cable arranger 3206 is the same as the cable arrangement speed on the reel assembly 3201 but the speeds of the cable arranger 3206 and the reel assembly 3201 are not the same, finely adjusts the rotating speed of the reciprocating driving motor 3207 until the speeds of the cable arranger and the reel assembly are the same; meanwhile, the position of the cable guide frame 3116 is adjusted by adjusting the length of the cable support arm 3106 and the height of the driving end of the first linear driver 3114, so that the cable guide frame 3206 can move to adapt to the cable arranger 3206, the cable bend angle is prevented from being too large, the cable is led to be in the best state from the reel assembly 3201 to the cable guide frame 3116 to the ground, the cable trend in the whole process is in the best state, and the service life of the cable is prolonged.

The cable winding device provided by the embodiment has at least the following advantages:

1. in this embodiment, the cable winder is equipped with a cable path control assembly 31, and when the cable winder is used, the cable winder is mounted on the mobile operation machine, and the cable is hung on the cable guide frame 3116, so that the rotating shaft 3103 is vertical or inclined, and the cable support arm 3106 is horizontal or inclined; during operation, the cable path control assembly 31 is driven by the rotating shaft 3103 to rotate in a horizontal plane or an inclined plane, so as to drive the cable guide frame 3116 with the cable penetrating through to rotate in the horizontal plane or the inclined plane, and further change the angle of the cable outgoing position relative to the mobile operation machine carrying the cable path control assembly; meanwhile, the distance from the cable guide 3116 to the rotation axis of the cable support arm 3106 is variable, so that the distance of the cable outgoing position relative to the moving operation machine on which the cable path control assembly is mounted can be changed, and the cable laying device can change the cable outgoing position. Therefore, the cable laying device provided by the embodiment can adjust the outgoing angle and position of the cable laying device according to the moving path of the cable laying device, so that the cable is laid outside the operating range of the mobile operation machine carrying the cable laying device, the interference with the machine tools equipped by the mobile operation machine is avoided, meanwhile, the path of the cable from the reel assembly 3201 to the ground is compliant, and the service life of the cable is prolonged;

2. in this embodiment, the controller of the cable winding device can control the rotation speed of the winding motor 3205 according to the collected moving speed of the cable winding device, so that the speed of releasing or winding the cable by the cable winding component 32 is adapted to the moving speed of the cable winding device, thereby avoiding over-tight cable laying and avoiding causing the cable winding device to fly (the cable winding device falls off from a mobile operation machine carrying the cable winding device);

second embodiment

With reference to fig. 4, the mobile cable winding device with power supply function provided in this embodiment is substantially the same as the basic structure, operation principle and technical effect of the first embodiment, except that: the cable path control assembly 31 includes a second linear actuator 3120, one end of the second linear actuator 3120 is hinged to the rotating shaft 3103, the other end of the second linear actuator 3120 is hinged to the cable arm 3106, and the cable arm 3106 is hinged to the rotating shaft 3103, so as to change the angle between the length direction of the cable arm 3106 and the length direction of the rotating shaft 3103 by the expansion and contraction of the second linear actuator 3120.

One end of a sliding sleeve 3105 of the cable support arm 3106 is hinged with the top end of the rotating shaft 3103, the other end of the sliding sleeve 3105 is hinged with one end of the second linear actuator 3120, and the other end of the second linear actuator 3120 is hinged with the rod part of the rotating shaft 3103. The second linear actuator 3120 is a linear actuator capable of changing its length, such as a pneumatic rod or an electric push rod; to ensure that the second linear actuator 3120 is able to provide sufficient thrust, a pneumatic rod is typically employed. The second linear actuator 3120, the rotating shaft 3103 and the sliding sleeve 3105 form a three-link mechanism whose length of one side is variable.

Therefore, the second linear actuator 3120 extends and retracts to drive the cable support arm 3106 to rotate up and down around the hinge axis of the sliding sleeve 3105 hinged to the rotating shaft 3103, thereby changing the distance from the cable guide 3116 to the base. For changing the distance of the cable guide 3116 from the predetermined axis due to the rotation of the cable arm 3106, compensation can be made by changing the distance of the cable guide 3116 from the rotation shaft 3103 by the extension and contraction of the third linear actuator 3108 to ensure that the position of the cable guide 3116 is adapted to the position of the cable arranger 3206.

In addition, in order to prevent the cable guide 3116 from twisting the cable during rotation of the cable support arm 3106, the upper end of the cable guide 3116 is hinged to the end of the cross bar of the cable support arm 3106, so that the cable guide 3116 is kept vertical during rotation of the cable support arm 3106, thereby preventing the cable guide 3116 from twisting the cable and ensuring the service life of the cable.
