[0018] Such as Figures 1-4The shown auxiliary device for winding and unwinding a charging pile cable includes an upper conveying box 1 and a lower conveying box 2. The upper conveying box 1 and the lower conveying box 2 are detachably and fixedly connected by bolts, so that other components of the entire auxiliary device are connected and isolated and protected through the upper conveying box 1 and the lower conveying box 2. A first rubber-coated roller 3 and a second rubber-coated roller 4 horizontally arranged are respectively rotatably connected to both ends of the upper conveying box 1 through bearings, so that the first rubber-coated roller 3 and the second rubber-coated roller 4 are connected to the upper conveying box 1, and it does not affect the rotation of the first rubber-coated roller 3 and the second rubber-coated roller 4 relative to the upper conveying box 1. At the same time, the first rubber-coated roller 3 and the second rubber-coated roller 4 are used to support the cable and reduce the friction when the cable passes through the upper conveying box 1. A third rubber-coated roller 6 horizontally arranged is rotatably connected to the middle of the upper conveying box 1 through a bearing, so that the third rubber-coated roller 6 is connected to the upper conveying box 1, and it does not affect the rotation of the third rubber-coated roller 6 relative to the upper conveying box 1. At the same time, it cooperates with the first rubber-coated roller 3 and the second rubber-coated roller 4 to support the cable and reduce the friction when the cable passes through the upper conveying box 1. A plurality of fourth rubber-coated rollers 5 vertically arranged are rotatably connected to the inner side end faces of both sides of the upper conveying box 1 through bearings, so that the fourth rubber-coated rollers 5 are connected to the upper conveying box 1, and it does not affect the rotation of the fourth rubber-coated rollers 5 relative to the upper conveying box 1. At the same time, it limits the passage of the cable through the upper conveying box 1 and reduces the friction when the cable passes through the upper conveying box 1.
[0019] As Figures 1-4 For the shown auxiliary device for winding and unwinding a charging pile cable, the first rubber-coated roller 3 or the second rubber-coated roller 4 or the third rubber-coated roller 6 or the fourth rubber-coated roller 5 is composed of a rotating roller and a rubber sleeve. The rubber sleeve wraps the outer end face of the rotating roller, so that the elasticity of the rubber sleeve is used to reduce the damage to the cable.
[0020] As Figures 1-4 For the shown auxiliary device for winding and unwinding a charging pile cable, a first pressing mechanism 15 and a second pressing mechanism 16 are respectively connected to the upper conveying box 1 above the first rubber-coated roller 3 and the second rubber-coated roller 4, forming a structure in which the cable can move as the first rubber-coated roller 3 and the second rubber-coated roller 4 rotate. So that the first pressing mechanism 15 and the second pressing mechanism 16 apply pressure to the cable passing through the upper conveying box 1, and further enable the cable to be in close contact with the first rubber-coated roller 3 and the second rubber-coated roller 4, thereby realizing the rotation of the first rubber-coated roller 3 and the second rubber-coated roller 4 to drive the cable to move, and further realizing the winding and unwinding of the cable.
[0021] As Figures 1-4The charging pile cable retracting and releasing assisting device shown includes a first pressing mechanism 15 or a second pressing mechanism 16 which comprises a press wheel mounting seat 17, a guiding plunger 21, a plunger spring 22, a plunger limiting plate 24 and a plurality of press wheel rubber-covered rollers 25. Adjusting holes 18 are formed in the side wall of the upper conveying box 1. Mounting bolts 19 are threadedly connected to both end faces of the press wheel mounting seat 17. The mounting bolts 19 are slidably connected in the adjusting holes 18, so that the press wheel mounting seat 17 is connected to the upper conveying box 1 through the mounting bolts 19 and the adjusting holes 18, and the press wheel mounting seat 17 can move reversely along the length of the adjusting holes 18, thereby adjusting the distances between the first pressing mechanism 15 and the first rubber-covered roller 3, and between the second pressing mechanism 16 and the second rubber-covered roller 4. The press wheel rubber-covered rollers 25 are rotatably connected to the press wheel mounting seat 17 through bearings, so that the press wheel rubber-covered rollers 25 are connected to the press wheel mounting seat 17, and it is not necessary for the press wheel rubber-covered rollers 25 to rotate relative to the press wheel mounting seat 17. At the same time, the press wheel rubber-covered rollers 25 are used to contact the cable, reducing the damage to the cable and the friction between the cable and the press wheel mounting seat 17. A plurality of guiding holes 20 are formed in the press wheel mounting seat 17. The guiding plunger 21 is arranged in the guiding holes 20, and both ends of the guiding plunger 21 are outside the guiding holes 20, so that the moving direction of the press wheel mounting seat 17 is limited through the guiding holes 20 and the guiding plunger 21, and the press wheel mounting seat 17 can only move along the length direction of the adjusting holes 18. The plunger spring 22 is sleeved outside the guiding plunger 21 in the guiding holes 20, so that the plunger spring 22 provides an elastic force for the press wheel mounting seat 17, and the press wheel mounting seat 17 is always close to the first rubber-covered roller 3 or the second rubber-covered roller 4 under the action of only the elastic force of the plunger spring 22. Furthermore, the elastic force of the plunger spring 22 provides a thrust for the cable, so that the cable is always in close contact with the first rubber-covered roller 3 and the second rubber-covered roller 4. The guiding plunger 21 is connected to the inside of the upper conveying box 1 through a fixing bolt 23, so that the guiding plunger 21 is connected to the upper conveying box 1, and thus the press wheel mounting seat 17 can move relative to the guiding plunger 21 and the upper conveying box 1. The plunger limiting plate 24 is detachably and fixedly connected to the press wheel mounting seat 17 through bolts, and the guiding plunger 21 passes through the plunger limiting plate 24, so that the guiding plunger 21 is limited by the plunger limiting plate 24. A limiting protrusion 26 extends in the middle of the guiding plunger 21. The plunger limiting plate 24 and the plunger spring 22 are respectively located at both ends of the limiting protrusion 26, so that the plunger spring 22 is limited by the limiting protrusion 26 to prevent the plunger spring 22 from disengaging from the guiding holes 20. In addition, the plunger limiting plate 24 can limit the guiding plunger 21 through the limiting protrusion 26, thereby limiting the moving distance of the press wheel mounting seat 17.
[0022] As Figures 1-4The shown auxiliary device for winding and unwinding the charging pile cable. The first rubber-coated roller 3 is connected to a driving mechanism arranged in the lower conveying box 2, so that the first rubber-coated roller 3 is driven to rotate by the driving mechanism, and then the cable is driven to move, realizing the winding and unwinding of the cable. The driving mechanism includes a DC motor 10, a reducer 11, a first synchronous pulley 8, a second synchronous pulley 7 and a first synchronous belt 9. The DC motor 10 and the reducer 11 are detachably and fixedly connected in the lower conveying box 2 by bolts, so that the DC motor 10 and the reducer 11 are connected to the lower conveying box 2 together. The DC motor 10 is a forward and reverse bidirectional motor, so that the DC motor 10 can rotate clockwise or counterclockwise, and thus it is convenient to realize the winding and unwinding of the cable. The output shaft of the DC motor 10 is connected to the input port of the reducer 11, so that when the DC motor 10 is powered on and works, its output shaft rotates, and then the rotational force is transmitted to the reducer 11. The first synchronous pulley 8 is connected to the output port of the reducer 11 through a rotating shaft, so that the rotational force of the conveyor reducer 11 is transmitted to the first synchronous pulley 8 through the rotating shaft, realizing the rotation of the first synchronous pulley 8. The first synchronous pulley 8 and the second synchronous pulley 7 are connected by a first synchronous belt 9, so that the rotation of the first synchronous pulley 8 drives the second synchronous pulley 7 to rotate through the first synchronous belt 9. The second synchronous pulley 7 is connected to the rotating shaft of the first rubber-coated roller 3 by bolts detachably or through a non-circular rotating shaft and a plug hole, so that the rotation of the second synchronous pulley 7 drives the first rubber-coated roller 3 to rotate.
[0023] As Figures 1-4 For the shown auxiliary device for winding and unwinding the charging pile cable, the first rubber-coated roller 3 and the second rubber-coated roller 4 are connected by a transmission mechanism, forming a structure in which the first rubber-coated roller 3 is driven to rotate by the driving mechanism, and the first rubber-coated roller 3 drives the second rubber-coated roller 4 to rotate through the transmission mechanism, so that the first rubber-coated roller 3 rotates to drive the second rubber-coated roller 4 to rotate in the same direction through the transmission mechanism, and thus it is convenient for the cable to move in the upper conveying box 1, realizing the winding and unwinding of the cable. The transmission mechanism includes a third synchronous pulley 12, a fourth synchronous pulley 13 and a second synchronous belt 14. The third synchronous pulley 12 is connected to the rotating shaft of the first rubber-coated roller 3 by bolts detachably or through a non-circular rotating shaft and a plug hole, so that the third synchronous pulley 12 and the first rubber-coated roller 3 are connected together, realizing simultaneous rotation. The fourth synchronous pulley 13 is connected to the rotating shaft of the second rubber-coated roller 4 by bolts detachably or through a non-circular rotating shaft and a plug hole, so that the fourth synchronous pulley 13 and the second rubber-coated roller 4 are connected together, realizing simultaneous rotation. The third synchronous pulley 12 and the fourth synchronous pulley 13 are connected by a second synchronous belt 14, so that the rotation of the first rubber-coated roller 3 drives the third synchronous pulley 12 to rotate, the third synchronous pulley 12 drives the fourth synchronous pulley 13 to rotate through the second synchronous belt 14, and the fourth synchronous pulley 13 drives the second rubber-coated roller 4 to rotate, thereby realizing the simultaneous rotation of the first rubber-coated roller 3 and the second rubber-coated roller 4 in the same direction.
[0024] In the above embodiments, the device components involved are all conventional device components unless otherwise specified. The structural settings, working methods, or control methods involved are all conventional settings, working methods, or control methods in this field unless otherwise specified.
[0025] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
