Description

Technical Field

[0001] The utility model relates to the technical field of rocker arm installation equipment, in particular to an assembly device for the rocker arm horizontal shaft of a CK vertical mill. Background Art

[0002] At present, there are two common methods for the primary assembly of the rocker arm horizontal shaft of a CK vertical mill: ① The horizontal mechanical pressing method of the horizontal shaft; ② The longitudinal hot-fitting method of the horizontal shaft. Through on-site discussion and research, it is found that in the horizontal mechanical pressing method of the horizontal shaft, during the mechanical pressing process of the horizontal shaft, there will be inner wall scratching phenomena in the pin holes on both sides of the roller arm, which cannot fully guarantee the product quality. And the longitudinal hot-fitting method of the horizontal shaft adopts a hot-fitting interference fit. Although it can guarantee the product quality and there is no inner wall scratching phenomenon in the pin holes on both sides of the roller arm, during the operation process, the rocker arm (which belongs to a non-standard oversized and overweight part) needs to be turned over 90° in the air and then lifted onto and off the shelf. This process is relatively cumbersome and the operation risk factor is relatively large.

[0003] For example, the publication number CN215946538U discloses a hoisting crane device on March 4, 2022, which includes: a workbench, a pair of guiding modules and an execution module; the pair of guiding modules are respectively arranged on both sides of the workbench, and the workbench is located between the pair of guiding modules; the execution module is respectively connected to the pair of guiding modules, and the execution module is located on one side of the workbench. The above-disclosed crane cannot perform stable horizontal movement on the rocker arm horizontal shaft during work, and its practicability is poor. Summary of the Invention

[0004] The purpose of the utility model is to provide an assembly device for the rocker arm horizontal shaft of a CK vertical mill with higher practicability. The utility model adjusts the angle between the crossbeam connecting rod and the support connecting rod through an adjustment component, and further adjusts the angle between the crossbeam connecting rod and the support connecting rod, thereby realizing the angle of the rocker arm horizontal shaft connected to the crossbeam connecting rod and achieving the stable installation of the rocker arm horizontal shaft, with higher practicability.

[0005] To achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is: an assembly device for the rocker arm horizontal shaft of a CK vertical mill, which includes a crossbeam connecting rod connected to the rocker arm horizontal shaft. A support rod is arranged on the crossbeam connecting rod, and a connecting hanging rod is arranged on the support rod. The connecting hanging rod is connected to the crossbeam connecting rod through an angle adjustment component.

[0006] The crossbeam connecting rod is hinged to the support rod, and the support rod is connected to the connecting hanging rod.

[0007] The angle adjustment component is a chain block. One end of the steel wire rope of the chain block is connected to the connecting hanging rod, and the other end of the steel wire rope of the chain block is connected to the crossbeam connecting rod.

[0008] The connecting suspension rod is T-shaped. A first connecting seat for connecting with a chain block is provided on the crossbeam connecting rod. A second connecting seat for connecting with a traveling crane hook is provided at one end of the connecting suspension rod. A third connecting seat for connecting with a chain block is provided at the other end of the connecting suspension rod.

[0009] A connecting sleeve is provided on the crossbeam connecting rod, and the connecting sleeve is connected with the rocker horizontal shaft.

[0010] A connecting flange is provided on the crossbeam connecting rod, and the connecting flange is connected with the connecting sleeve through bolts.

[0011] The beneficial effects of the present utility model are as follows:

[0012] By adjusting the angle between the crossbeam connecting rod and the support rod through the angle adjusting component, the horizontal state between the crossbeam connecting rod and the rocker horizontal shaft is ensured, which is convenient for the rocker horizontal shaft to be horizontally inserted into the hydraulic cylinder arm for assembly, avoiding scratches on the inner walls of the pin holes on both sides of the grinding roller arm, and also avoiding the 90° turning over operation of the rocker in the air for lifting and lowering. The process is relatively simple, the risk coefficient is reduced, and the operation safety is guaranteed.

[0013] A connecting sleeve is provided on the crossbeam connecting rod, and the connecting sleeve is connected with the rocker horizontal shaft. The convenient connection between the rocker horizontal shaft and the crossbeam connecting rod is realized through the connecting sleeve, and connecting sleeves of different specifications can be replaced for the assembly of rocker horizontal shafts of different models of CK vertical mills, with higher practicability.
