Description

Technical Field

[0001] The utility model relates to a floor door device for logistics warehousing, belonging to the technical field of logistics warehousing equipment. Background Art

[0002] Logistics storage floor doors refer to doors used to connect different levels in logistics storage buildings. In modern logistics storage buildings, due to the requirements of space utilization, multi-layer structures are often adopted, that is, multiple vertical levels are set up in one building, and each level is connected by facilities such as elevators, escalators or stairs. Logistics storage floor doors are usually doors located between each level so that goods and personnel can enter and exit conveniently. Unlike ordinary doors, logistics storage floor doors usually have larger sizes and carrying capacities so that they can accommodate the entry and exit of large goods and equipment; they also need to have certain safety performance to ensure the safety of goods and personnel. When designing and manufacturing logistics storage floor doors, many factors need to be considered, such as the material, structure, size, carrying capacity, opening method, safety performance, etc. of the door. The Chinese invention patent with patent number CN201911393755.1 discloses a floor door mechanism and a logistics conveying system of a vertical sorting machine, by installing unlocking devices at different positions in the vertical direction of the floor door body, so that the elevator cars located at different positions of the floor door body can open the floor door body.

[0003] However, the inventor of the utility model found that the prior art has the following problems: the opening and closing of traditional floor doors often use hydraulic drive, which has the disadvantage of slow movement; or pneumatic drive, when the pressure is adjusted to a small level, the speed cannot meet the requirements; the pressure is too high, and the terminal brake inertia is large. Even if there is a buffer, it will cause impact on the floor door, affecting the service life of the floor door. Therefore, it is necessary to find a floor door with appropriate speed, small rigid impact, and fireproof. Utility Model Content

[0007] The power assembly comprises a motor, a motor mounting plate and a first coupling; the motor output shaft passes through a through hole of the motor mounting plate and is fixedly connected to the first coupling.
