Description

Technical Field

[0001] The utility model relates to the technical field of lifting chains, in particular to a novel high-wear-resistant carburized lifting chain. Background Art

[0002] The lifting chain is an indispensable and important lifting device for cranes. The length of the chain can be adjusted according to the lifting height of the object being lifted. It plays an important role in improving the operating efficiency of the crane and expanding the operating range of the crane.

[0003] During the use of the lifting chain, if the hoisted object is too large or too heavy, the lifting chain will be damaged faster due to overload. After the existing lifting chain is damaged, since most of the existing lifting chains are made of interlocking steel rings, when a steel ring in a certain middle part breaks due to overload, the original whole chain will be divided into two sections, which is difficult to reconnect. In order to meet the use needs, it is necessary to discard the original two broken chain sections and re-purchase a complete chain, which increases the use cost. Utility Model Content

[0004] The utility model aims to provide a novel highly wear-resistant carburized lifting chain to solve the problem raised in the above-mentioned background technology that during the use of the lifting chain, if the hoisted object is too large or too heavy, the lifting chain will be damaged faster due to overload. After the existing lifting chain is damaged, since most of the existing lifting chains are made of interlocking steel bars, after a steel bar ring in a certain middle part breaks due to overload, the original whole chain will be divided into two sections, which is difficult to connect. In order to meet the use demand, it is necessary to discard the original two broken chain sections and re-purchase a complete chain, which increases the use cost.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a novel high wear-resistant carburized lifting chain, comprising an upper chain ring and a lower chain ring, wherein the upper chain ring and the lower chain ring are provided with a connecting mechanism to the outside, and the upper chain ring and the lower chain ring are provided with a heat dissipation mechanism on the outside;

[0006] The connecting mechanism includes a rotating groove, a rotating ring is rotatably connected to the inner side of the rotating groove, a rotating block is fixedly connected to the bottom of the rotating ring, a threaded rod is fixedly connected to the bottom of the rotating block, a threaded hole is opened on the outside of the threaded rod, and a fixing column is threadedly connected to the inside of the threaded hole.

[0007] Preferably, the rotating groove is opened at the bottom of the upper chain ring, and the rotating ring is configured to be T-shaped.

[0008] Preferably, one end of the threaded rod is threadedly connected to one end of the lower chain ring, and a buffer pad is installed at the bottom of the rotating block.

[0009] Preferably, a plurality of the fixing columns are provided, and the plurality of the fixing columns are distributed in a linear array.

[0010] Preferably, a thread is disposed on the outside of the fixing post, and the fixing post passes through the lower chain ring and extends to the outside of the lower chain ring.

[0011] Preferably, the heat dissipation mechanism comprises a first heat dissipation tube and a second heat dissipation tube, a plurality of through holes are formed on the inner sides of the first heat dissipation tube and the second heat dissipation tube, and heat conducting sheets are installed on the inner sides of the first heat dissipation tube and the second heat dissipation tube.

[0012] Preferably, the first heat dissipation pipe is fixedly connected to the outside of the upper chain ring, and the second heat dissipation pipe is fixedly connected to the outside of the lower chain ring.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, the utility model aligns the bottom of the upper chain ring with the top of the lower chain ring, and then allows the rotating block to rotate through the provided rotating groove and rotating ring, and then the staff can rotate the rotating block so that the threaded rod at the bottom of the rotating block spirals into the interior of the lower chain ring, so that the upper chain ring and the lower chain ring are connected, and the buffer pad at the bottom of the rotating block provides a buffer for the pressure generated during lifting, and then screws a plurality of fixing columns into the threaded holes of the threaded rod in sequence to further improve the stability of the connection, and through a plurality of fixing columns, the lateral connection is also more stable, and then the exterior of the lifting chain is carburized to form a high-hardness carburized layer on the surface of the chain, thereby significantly improving the wear resistance and fatigue resistance of the chain, and then completing the connection operation, so that there is no need to repurchase the chain after it breaks, thereby achieving the effect of cost saving.

[0015] Second, the utility model can increase the flow rate of air around the chain by installing the first heat dissipation pipe and the second heat dissipation pipe on the outside of the upper chain ring and the lower chain ring respectively, and then allow air to enter the through hole through the through hole. Then, the heat of the chain is conducted through the heat conducting sheet, so that the heat is introduced into the through hole, and then the air flow can take away the heat, thereby reducing the temperature of the chain, and then completing the heat dissipation operation, thereby extending the service life and ensuring the stability of the chain.
