However, the above process requires precise control of crane equipment, which is not only difficult to operate and has poor accuracy, but also easy to damage the expansion sleeve and expansion joint due to continuous collision during the expansion process, which increases the expansion cost.

[0041] Embodiment 1

[0042] Therefore, if Figure 1-Figure 6 As shown, this embodiment provides a ring network cabinet to solve the above problems. The ring network cabinet includes a ring network cabinet body 1 and a docking assembly 2, the docking assembly 2 is arranged on the ring network cabinet body 1 along a first direction (i.e., the X direction in the figure), and the docking assembly 2 includes a docking body 21, a slide groove 211 is opened on the docking body 21 along the first direction, and a guide member 22 is arranged in the slide groove 211, and the guide member 22 can extend relative to the docking body 21 of one of the ring network cabinets, and the slide groove 211 of the other ring network cabinet can be slidably arranged on the guide member 22 to guide the movement of the other ring network cabinet, thereby improving the docking accuracy, avoiding damage to the expansion joint and the expansion sleeve on the ring network cabinet, and reducing the expansion cost.

[0043] The ring network cabinet also includes a rolling member 3, which is arranged at the bottom end of the ring network cabinet body 1 and can abut against the ground to reduce the friction between the bottom end of the ring network cabinet and the ground, improve the smoothness of the movement and steering of the ring network cabinet, and facilitate manual change of the direction of the ring network cabinet, and convert the fine control of crane-type equipment into manual steering of the ring network cabinet, thereby reducing the difficulty of docking between multiple ring network cabinets and improving the docking efficiency.

[0044] Optionally, the bottom of the chute 211 is provided with a plurality of first positioning holes 2111 at intervals along the first direction, the guide member 22 is provided with a second positioning hole 221, and the positioning member 23 passes through the second positioning hole 221 and the first positioning hole 2111 in sequence to achieve the fixing of the guide member 22 in the chute 211, thereby avoiding the reduction of docking accuracy due to the movement of the guide member 22 in the chute 211. Moreover, the setting of the plurality of first positioning holes 2111 makes the position of the guide member 22 in the chute 211 adjustable, so as to adjust the extension amount of the guide member 22 relative to the docking body 21. Further, optionally, a plurality of second positioning holes 221 are provided, and the plurality of second positioning holes 221 are arranged at intervals along the first direction, and the positioning member 23 is arranged one by one with the second positioning hole 221, so as to improve the connection strength between the guide member 22 and the docking body 21. Further, the positioning member 23 can be a component with a fastening function such as a bolt, a screw, or a screw, which will not be described in detail here.

[0045] Optionally, the docking assembly 2 is divided into a first docking assembly 24 and a second docking assembly 25, the first docking assembly 24 is arranged on the side wall of the ring main unit body 1, the second docking assembly 25 is arranged at the bottom end of the ring main unit body 1, and the rolling member 3 is connected to the second docking assembly 25. Further optionally, a plurality of first docking assemblies 24 are provided, and the plurality of first docking assemblies 24 are arranged at intervals along the vertical direction (i.e., the Z direction in the drawings). The addition of the docking assembly 2 can improve the stability of docking between multiple ring main units.

[0046] Specifically, the docking body 21 is divided into a first docking body 212 and a second docking body 213. The first docking assembly 24 includes the first docking body 212. The side of the first docking body 212 opposite to the slide groove 211 is a plane, so as to facilitate the installation of the first docking assembly 24 on the side wall of the ring network cabinet body 1. The second docking assembly 25 includes the second docking body 213. The side of the second docking body 213 away from the slide groove 211 is provided with a receiving groove 2131, and the rolling element 3 is arranged in the receiving groove 2131. Further optionally, the groove wall of the receiving groove 2131 in contact with the bottom end of the ring network cabinet body 1 is provided with a mounting hole 2134, and the top end of the rolling element 3 is provided with a mounting protrusion 32, and the mounting protrusion 32 can be arranged in the mounting hole 2134 to achieve the connection between the rolling element 3 and the second docking assembly 25. The bottom end of the rolling element 3 is rotatably provided with a universal wheel 31, which can abut against the ground, reducing the friction between the bottom end and the ground during the docking process of the ring main unit, improving the smoothness of the movement and steering of the ring main unit, so as to facilitate the adjustment of the position of the ring main unit during the docking process. Further optionally, a plurality of mounting holes 2134 are provided, and the mounting protrusions 32 are arranged one by one with the mounting holes 2134, so as to enhance the stability of the installation of the rolling element 3 in the receiving groove 2131.

[0047] Further optionally, two rolling members 3 are provided, and the two rolling members 3 are arranged at intervals at the bottom end of the ring main unit body 1 along the second direction (i.e., the Y direction in the figure) to improve the stability of the ring main unit during the docking process. The first direction and the second direction are arranged vertically in the horizontal plane. Further optionally, the rolling members 3 are arranged one-to-one with the second docking assembly 25, so that each rolling member 3 can be accommodated in the second docking assembly 25, avoiding the rolling member 3 from being exposed to the outside and always in contact with the ground, thereby avoiding the position of the ring main unit from being offset after the docking is completed.

[0048] The ring main unit has two states: one is that the rolling member 3 is in direct contact with the ground during docking, which is convenient for the turning of the ring main unit; the other is that the rolling member 3 is not in contact with the ground after docking, which is convenient for the stable placement of the ring main unit on the ground. Therefore, the ring main unit may further include an adjustment member 4 connected to the bottom end of the second docking body 213, which is used to adjust whether the rolling member 3 is in direct contact with the ground.

[0049] Specifically, the bottom end of the second docking body 213 is provided with a relief protrusion 2132, and the adjustment member 4 is an L-shaped plate, which includes a first plate and a second plate. The top of the first plate is provided with a relief groove 41, and the second plate is provided with a through groove 42, which is connected to the receiving groove 2131. When the relief protrusion 2132 is arranged in the relief groove 41, the rolling member 3 is arranged in the receiving groove 2131 and does not contact the ground; when the groove wall of the relief groove 41 abuts against the side of the second docking body 213 provided with the slide groove 211, the rolling member 3 passes through the through groove 42 and contacts the ground. It can be seen from the above that by adjusting the different positions of the adjustment member 4 on the second docking body 213, the switching of whether the rolling member 3 contacts the ground can be achieved. Further, when the rolling member 3 does not contact the ground, the adjustment member 4 contacts the ground to achieve stable placement of the ring network cabinet on the ground. Furthermore, a plurality of anchor bolts are provided at the bottom end of the adjusting member 4, and the anchor bolts can be connected to the ground to fix the position of the ring main unit.

[0050] Further optionally, a first fixing hole 2133 is provided on the giving way protrusion 2132, a second fixing hole 43 is provided on the first plate, and the fastener 26 can pass through the second fixing hole 43 and the first fixing hole 2133 in sequence to achieve the connection between the adjustment member 4 and the second docking body 21321. Further optionally, a plurality of the first fixing holes 2133 and the second fixing holes 43 are provided, and are spaced apart along the first direction to improve the stability of the connection between the adjustment member 4 and the second docking body 213. Further, the fastener 26 can be a component with a fastening function such as a bolt, a screw, or a screw, which will not be described in detail here.

[0051] Further optionally, the second fixing hole 43 includes a first half hole 431 and a second half hole 432, and the first half hole 431 is connected to the second half hole 432. When the fastener 26 passes through the first half hole 431 and is connected to the first fixing hole 2133, the rolling member 3 is arranged in the accommodating groove 2131 so that the bottom end of the adjusting member 4 is connected to the ground, which is convenient for the stable placement of the ring network cabinet; when the fastener 26 passes through the second half hole 432 and is connected to the first fixing hole 2133, the rolling member 3 passes through the through groove 42 and contacts the ground, so that the rolling member 3 abuts against the ground, which is convenient for the turning and movement of the ring network cabinet.

[0052] Embodiment 2

[0053] The difference between this embodiment and the first embodiment lies in the adjustment method of the rolling element 3, and the other parts are the same, which will not be described in detail here. The adjustment method of the rolling element 3 is discussed in detail below:

[0054] Optionally, a through slot 42 is provided on the slot wall of the receiving slot 2131 close to the ground, and the rolling element 3 further comprises a telescopic rod, the top end of the telescopic rod is connected to the slot wall of the receiving slot 2131 close to the ring main unit, and the bottom end of the telescopic rod is provided with a universal wheel 31, which can be arranged in the receiving slot 2131 or pass through the through slot 42 to contact the ground. As can be seen from the above, the position of the universal wheel 31 can be adjusted by extending and retracting the telescopic rod.
