Description

Technical Field

[0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a cable reel with a cable outlet capable of rotating 360 degrees. Background Art

[0002] At present, one of the power supply methods for large and medium-sized mobile electrical equipment is to use a cable reel power supply method. By using the fast retraction and release function of the cable reel, a power supply circuit between the mobile device and the power source can be quickly and conveniently built to ensure that the electrical equipment can be moved within a certain distance. However, there are some problems in the current application of cable reels, that is, the electrical equipment can only move in the direction of the cable reel outlet. If it deviates from this direction, the cable will be subject to greater resistance, which will have an adverse effect on the cable. Summary of the invention

[0003] The object of the present invention is to provide a cable reel with a cable outlet that can rotate 360 ​​degrees, so as to overcome the defect that the cable reel in the prior art cannot automatically change the outlet direction.

[0004] The present invention is implemented by adopting the following technical scheme: a cable reel with a line outlet that can rotate 360 ​​degrees, comprising a mounting frame, a power device and a reel body being mounted on the mounting frame, the reel body comprising a reel, an upper retaining ring and a lower retaining ring being respectively mounted on the upper and lower sides of the reel, the power device being connected to the reel through a rotating shaft, a line outlet assembly being arranged on the upper side of the upper retaining ring, the line outlet assembly comprising a connecting plate, one end of the connecting plate being movably connected to the reel and fixedly connected to at least one mounting plate, the connecting plate rotating relative to the reel, the other end of the connecting plate being connected to the line outlet, a friction assembly being arranged on the lower side of the lower retaining ring, the friction assembly comprising a friction disc and a friction column, the friction disc being fixed to the mounting frame through a friction disc bracket, a vertical guide rod being mounted between the mounting plate and the friction disc, a friction column being mounted on the guide rod, the friction column being movable up and down along the guide rod, an elastic member being mounted between the friction column and the mounting plate, and a cushion block being mounted between the elastic member and the friction column.

[0005] Furthermore, a bearing is installed between the connecting plate and the reel.

[0006] Furthermore, the wire outlet includes a horizontal guide roller and a vertical guide roller.

[0007] Furthermore, the number of the mounting plates is three.

[0008] Furthermore, the elastic member is a spring.

[0009] Furthermore, the power device is an electric motor.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The outlet direction of the outlet of the present invention can be automatically changed as the length direction of the cable changes, which solves the problem that the cable reel in the prior art cannot automatically change the outlet direction. By connecting one end of the connecting plate to the reel and installing a bearing between the reel and the connecting plate, the cable contacts the guide roller on the outlet when it is outgoing. When the length direction of the cable changes, the cable will bend with the outlet of the outlet. At this time, the cable will push the outlet assembly to rotate around the reel, so that the outlet is adapted to the length direction of the cable, avoiding bending of the cable when it is reeled. When rotating, the friction column will contact the friction disk to generate friction to avoid excessive rotation of the reel.

[0012] 2. The present invention solves the problem that the cable reel may slip off the reel when collecting the cable. During processing, the present invention makes the distance from the outer circumference of the upper retaining ring and the lower retaining ring to the friction column smaller than the outer diameter of the cable, so that the cable cannot leak out from the gap between the upper retaining ring and the lower retaining ring and the friction column, thereby ensuring the reliability of the cable reel when in use.

DETAILED DESCRIPTION

[0019] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0020] Embodiment 1:

[0021] A cable reel with a 360° rotatable outlet comprises a mounting frame 1, a power device 2 and a reel body are mounted on the mounting frame 1, the reel body comprises a reel 3, an upper retaining ring 4 and a lower retaining ring 5 are respectively mounted on the upper and lower sides of the reel 3, the power device 2 is connected to the reel 3 through a rotating shaft, an outlet assembly is arranged on the upper side of the upper retaining ring 4, the outlet assembly comprises a connecting plate 6, one end of the connecting plate 6 is movably connected to the reel 3 and fixedly connected to at least one mounting plate 7, the connecting plate 6 rotates relative to the reel 3, the other end of the connecting plate 6 is connected to the outlet 8, a friction assembly is arranged on the lower side of the lower retaining ring 5, the friction assembly comprises a friction disc 9 and a friction column 10, the friction disc 9 is fixed to the mounting frame 1 through a friction disc bracket 11, a vertical guide rod 12 is installed between the mounting plate 7 and the friction disc 9, the friction column 10 is installed on the guide rod, the friction column 10 can move up and down along the guide rod 12, an elastic member is installed between the friction column 10 and the mounting plate 7, and a cushion block 13 is installed between the elastic member and the friction column 10.

[0022] When the present invention is used, the cable is wound between the upper retaining ring 4 and the lower retaining ring 5 , and one end of the cable is led out through the outlet 8 and contacts the vertical guide roller 15 and / or the horizontal guide roller 14 .

[0023] The present invention can change the friction between the friction column 10 and the friction plate 9 by changing the thickness of the pad 13. When we want to increase the friction between the friction column 10 and the friction plate 9, we only need to increase the thickness of the pad 13. At this time, the pressure of the friction column 10 on the friction plate 9 increases due to the increase in the elastic force of the spring 16 and the gravity of the pad 13. Figure 3 and Figure 4 As shown, the friction column 10 is pressed against the friction disk 9 under the pressure of the spring 16 and the action of gravity. The friction force between the friction column 10 and the friction disk 9 can be adjusted by adjusting the thickness of the pad 13, so that the friction torque Tfriction between the friction column 10 and the friction disk 9 is smaller than the torque Tswing generated on the outlet 8 when the cable swings left and right during the cable winding, and is larger than the torque Tbending generated on the outlet 8 when the cable drum 3 collects the cable. Tswing refers to the torque of the cable on the outlet 8 when the swinging direction of the cable is different from the winding direction. At this time, since Tfriction is smaller than Tswing, the torque Tswing causes the outlet assembly to rotate, even if the outlet direction of the outlet 8 is rotated to adapt to the length direction of the cable, the cable is prevented from bending during the winding. Tbending refers to the torque of the cable on the outlet 8 when the length direction of the cable is substantially the same as the outlet direction of the outlet 8, that is, when the cable is substantially not bent during the winding, Tfriction is greater than Tbending, and the outlet assembly does not rotate.

[0024] The friction column 10 of the present invention has a guide hole formed therein, and the guide rod 12 passes through the guide hole.

[0025] The distance between the outer circumference of the upper retaining ring 4 and the lower retaining ring 5 and the friction column 10 is smaller than the outer diameter of the cable, so that the cable cannot leak out from the gap between the upper retaining ring 4 and the lower retaining ring 5 and the friction column 10, that is, it cannot escape from the reel 3.

[0026] When the connecting plate 6 of the present invention rotates, the mounting plate 7 is driven to rotate at the same time.

[0027] A bearing is installed between the connecting plate 6 and the reel 3 .

[0028] The bearing of the present invention can effectively reduce the friction between the connecting plate 6 and the reel 3, so that when the reel 3 rotates, the connecting plate 6 can stop rotating under the action of the friction column 10 and the friction disk 9.

[0029] The wire outlet 8 includes a horizontal guide roller 14 and a vertical guide roller 15 .

[0030] The horizontal guide roller 14 and the vertical guide roller 15 of the present invention can rotate relative to the cable outlet 8, so as to further reduce the friction force when the cable is discharged or collected.

[0031] The number of the mounting plates 7 is three.

[0032] The present invention increases the number of mounting plates 7, that is, increases the number of friction columns 10, thereby enhancing the working stability and friction force.

[0033] The elastic member is a spring 16 .

[0034] The power device 2 is an electric motor.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
