Description

Technical Field

[0001] The utility model relates to the technical field of silent shells, and more specifically, to a silent shell with stable connection. Background Art

[0002] A crane is a common name for a hoist, which is widely used in a series of heavy industrial products such as ships, equipment, machinery, and molds. A crane consists of a power device and a bracket. The power device consists of a motor, a reducer, a clutch, a brake, a rope drum, and a steel wire rope. The motor, as the driving part of the crane, is mainly used for winding the steel wire rope. The noise generated during the use of the motor interferes with the work of workers.

[0003] After retrieval, the utility model patent with the publication number of CN216163104U discloses a combined silent shell assembly for a hoist, including a fixed base and a protective shell. The protective shell is installed at the top of the fixed base. Symmetric positioning card slots are opened on the left side of the top of the fixed base, and a positioning baffle is welded on the right side of the top of the fixed base. T-shaped card slots are symmetrically opened at both ends of the fixed base, and positioning blocks are arranged on both sides of the bottom end of the protective shell. Through the cooperation of the positioning card slots, the positioning blocks and the positioning baffle, the installation of the protective shell can be positioned and limited. Through the cooperation of the T-shaped card slots, the fixed blocks, the fixed card holes, the fixed bolts, the positioning baffle, the connecting screw holes and the connecting card holes, the splicing and assembly between the protective shell and the fixed base can be fixed, reducing the assembly difficulty of the hoist shell and facilitating the disassembly, replacement and maintenance of the hoist shell by workers. However, the above patent still has the following deficiencies: the fixed bolts are directly exposed outside, and the fixed bolts are easily affected by the external environment and rust, which is likely to cause the installation of the protective shell to become loose after a long time. In addition, when the lifting motor is installed on the base and driven, certain vibrations will occur on the base plate, which will cause the bolts for installing the protective shell to become loose, affecting the stability of the installation of the protective shell. Therefore, we propose a silent shell with stable connection. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a silent shell with stable connection.
