Fig. 1 shows an exemplary perspective view of a chain link hoop 100 according to an embodiment of the present application. Fig. 2 shows another exemplary perspective view of the chain hoops according to an embodiment of the application. In the embodiment shown in fig. 1 and 2, the chain link hoop 100 includes a plurality of intermediate link units 200 and end links 300. The intermediate link units 200 are connected to each other by a first connection piece 220 passing through a first connection hole 211 in the chain block 210.

In this embodiment, the first connector 220 includes a first bolt 221, a nut, and a first connector piece 222, the first bolt 221 passing through a hole in the first connector piece 222.

It should be appreciated that the first connector 220 may be any suitable device suitable for connecting two chain blocks 210.

In this embodiment, the chain block 210 and the end link 300 are each configured as an integrally formed piece, such as manufactured by casting, molding, or metal extrusion process, thereby ensuring, on the one hand, the load-bearing capacity and durability of the chain block 210 and the end link 300, and, on the other hand, simplifying the manufacturing process and reducing the cost.

In fig. 1 and 2, the chain link hoop 100 is mounted to a tower or a tower pole, and the tower or the tower pole is not shown in the drawings in order to more clearly show the chain link hoop 100. In this state, other related devices may be mounted to the chain hoops 100 through the connectors.

Fig. 3 illustrates an exemplary perspective view of the chain blocks 210 of the chain link hoop 100 according to an embodiment of the present application, and fig. 4 illustrates another exemplary perspective view of the chain blocks 210 of fig. 3 of the chain link hoop 100 according to an embodiment of the present application.

As shown in fig. 3 and 4, in this embodiment, the chain blocks 210 are curved on the radially inward side to enable better engagement with the pylon or mast to be installed, thereby better transferring loads and improving stability.

The first connection holes 211 are located at both ends of the link blocks 210 for connecting with other link blocks 210 or end links 300 through the first connection members 220 or with the second connection members 320.

In this embodiment, the first connection hole 211 is substantially circular in cross section and is opened in a direction toward the inside of the link block 210, thereby ensuring stable connection with the first connector 220 or with the second connector 320 while reducing the weight of the link block 210 itself.

The chain block 210 is further provided with lightening holes 212, and the lightening holes 212 can be arranged in any appropriate shape under the condition of ensuring the performance of the chain block 210, so as to lighten the weight of the chain block per se as much as possible and reduce the production and transportation cost. In this embodiment, the first connection hole 211 communicates with the lightening hole 212 in a direction toward the inside of the chain block 210.

As shown, ribs 213 are provided between the lightening holes 212. The rib-like portion 213 is provided substantially between the radially inner and outer side portions of the chain block 210 to improve the rigidity of the chain block 210. It should be understood that the size and shape of the ribs 213 may also be varied by adjusting the size and shape of the lightening holes 212 as required by various aspects of loading, etc.

The radially outward end of the rib 213 is substantially aligned with the mounting portion 216 to enable sufficient support of the load of the equipment to be mounted.

In this embodiment, the chain block 210 is provided with a mounting hole 214 in a mounting portion 216 that protrudes radially outward, wherein the mounting hole 214 is a closed through-hole. In this embodiment, the chain block 210 is provided with two mounting portions 216, each mounting portion 216 is provided with one mounting hole 214 having a circular cross section, and the wall thickness of the mounting hole 214 is substantially the same as the wall thickness elsewhere in the chain block 210. However, it should be understood that, in order to meet the requirements of different devices to be mounted with respect to the utility model of load-bearing performance and the like, the shape and number of the mounting holes 214 in the mounting portions 216 and each of the mounting portions 216 and the wall thickness configuration of the mounting holes 214 may be appropriately changed.

In this embodiment, since the mounting portion 216 protrudes radially outward from the chain block 210, the size of the mounting hole 214 is not limited by the thickness of the chain block 213, so that the load-bearing capacity of the chain block 210 is improved, the safety protection performance is enhanced, and the load-bearing performance of the chain hoop 100 is fully exerted.

In addition, because the installation part 216 which protrudes outwards in the radial direction is adopted, the device to be installed does not need to be tightly attached to a column or a pipe in the installation process, so that the installation and the maintenance are more convenient and quicker.

Fig. 5 illustrates an exemplary top view of the chain blocks 210 shown in fig. 3 of the chain link hoop 100 according to an embodiment of the present application. As can be better seen in fig. 5, there is a smooth circular arc transition 217 between the mounting portion 216 and the link block 210. The smooth arc transition portion 217 can ensure that the load from the mounting portion 216 is transmitted to other portions of the chain block 210 on a larger cross section, reduce stress concentration, further improve the bearing capacity of the mounting portion 216, and improve the overall performance of the chain hoop 100.
