Description

Technical Field

[0001] The utility model belongs to the technical field of equipment devices, mainly to the field of instrument device installation equipment, and specifically is a liftable and telescopic motor installation device used in a narrow cabinet. Background Art

[0002] The electrical control cabinet in the wrapping workshop is used to centrally place electrical equipment such as motors, controllers, and circuit boards. It is also called an electrical control cabinet or electrical cabinet or cabinet, in which electrical equipment is centrally installed and connected to circuits and systems to facilitate electrical control of production equipment. The electrical control cabinet can provide functions such as power distribution, circuit protection, and signal control, making the operation of the entire wrapping workshop safer and more reliable. During the assembly and maintenance of the electrical cabinet, the motor is one of the heavy equipment that often needs to be disassembled, replaced, and installed. However, there are many deficiencies and defects in the manual lifting and installation of heavy equipment in the cabinet, which may bring potential hazards to operators and equipment.

[0003] First, manually lifting heavy equipment may bring risks of personal injury to operators. Since heavy equipment is difficult to control, improper operation may cause accidental injuries such as equipment falling or sliding, especially when the equipment needs to be installed at a high place in a narrow cabinet, the consequences of such injuries may be more serious.

[0004] Secondly, heavy equipment may be damaged during manual operation. Improper operation may cause scratches and wear on the surface of the equipment, or even cause the equipment to break when the operation is wrong. This damage not only affects the appearance of the equipment, but may also affect the service life and normal operation of the equipment.

[0005] Third, there are installation quality risks when relying on manpower for installation. Since the accuracy and stability of manual operation are relatively low, it is easy to cause unstable equipment installation and large errors, which will affect the performance and safety of the equipment. In addition, manual handling and installation of heavy equipment are relatively inefficient and inconvenient. The narrow space cannot accommodate many people, and can only be lifted and installed with both hands, so it takes a long time and may affect the overall progress of the project. Such inefficiency may bring unnecessary delays and additional costs to the project. Manual lifting of heavy equipment will also lead to loss of labor. Due to the need for a lot of physical labor, operators may feel tired and exhausted, and long-term operation of such equipment may increase the risk of occupational diseases.

[0006] Finally, using manual lifting to install heavy equipment may delay troubleshooting and recovery time. In the case of emergency equipment failure, manual operation usually consumes more time and energy, thus delaying the troubleshooting time. Utility Model Content
