Description

Technical Field

[0001] This utility model relates to the field of industrial door machine technology, specifically to a door drive device with explosion-proof function. Background Technology

[0002] Industrial door operators, such as industrial overhead doors and sliding doors, are widely used in various industrial plants and warehouses. These locations may contain flammable gases, dust, and other explosive substances, thus imposing stringent requirements on the explosion-proof performance of electrical equipment. Explosion-proof electrical equipment is one of the key pieces of equipment for ensuring safe production in explosive environments. Its principle is to enclose components that may generate electrical sparks within a robust housing, thereby preventing ignition of the external environment.

[0003] The existing explosion-proof industrial door actuators have complex internal structures and are space-constrained, making it very difficult to fit the motor, reducer and transmission mechanism into a single enclosed housing. Furthermore, when the motor, controller or clutch mechanism inside the equipment needs to be repaired, replaced or reconnected, the entire machine must be removed from its installation position, making the maintenance process time-consuming and labor-intensive.

[0004] Therefore, there is an urgent need in this field for a door drive device solution that meets stringent explosion-proof standards while also offering advantages such as easy assembly and maintenance. Utility Model Content

[0005] To address the aforementioned technical deficiencies, this invention provides a door drive device with explosion-proof functionality, which is easy to assemble.

[0006] This utility model discloses a door drive device with explosion-proof function, including a housing. Inside the housing are a motor, a reducer, and a quick-clutch mechanism. One end of the motor shaft is connected to the input shaft of the reducer via the quick-clutch mechanism. A mounting port is provided on the housing corresponding to the other end of the motor shaft. A cover plate is provided on the mounting port, and the cover plate and the mounting port are sealed and fixed together. A mounting hole is provided on the cover plate, and a copper sleeve is provided in the mounting hole. One end of the motor shaft passes through the copper sleeve, and the inner side of the copper sleeve and the motor shaft form an explosion-proof surface. A manual switch assembly is provided on the outer side of the cover plate. The component is connected to the motor shaft for transmission. The reducer includes an output shaft. A second mounting hole is provided on the housing corresponding to the position of the reducer output shaft. A second copper sleeve is provided on the second mounting hole. One end of the reducer output shaft passes through the second copper sleeve. The inner side of the second copper sleeve and the output shaft form a second explosion-proof surface. A second mounting port is provided on the housing corresponding to the other end of the reducer output shaft. A second cover plate is provided on the second mounting port. The second cover plate and the second mounting port are sealed and fixed. A third mounting hole is provided on the second cover plate. A third copper sleeve is provided on the third mounting hole. The other end of the reducer output shaft passes through the third copper sleeve. The inner side of the third copper sleeve and the output shaft form a third explosion-proof surface.

[0007] During assembly, the motor, quick-clutch mechanism, and reducer are assembled as a single unit outside the housing. The first and second cover plates are removed. The motor shaft can be inserted into the housing at an angle, passing through the first mounting port. Then, the motor, quick-clutch mechanism, and reducer are inserted into the housing as a whole through the second mounting port. After insertion, one end of the reducer output shaft passes through the second copper sleeve. Finally, the first and second cover plates are installed. When installing the first cover plate, the motor shaft passes through the first copper sleeve on the first cover plate. A manual switch assembly is then installed on the first cover plate, connecting it to the motor shaft. When installing the second cover plate, the other end of the reducer output shaft passes through the third copper sleeve on the second cover plate.

[0008] To facilitate maintenance and wiring, a controller is installed on the motor. A maintenance port is provided on the housing corresponding to the positions of the controller and the quick clutch mechanism. A No. 3 cover plate is installed on the maintenance port, and the No. 3 cover plate is sealed and fixed to the maintenance port.

[0009] The door drive device with explosion-proof function obtained by this utility model has the following advantages: by adopting a structural design that combines a detachable sealing cover plate with a copper sleeve, the assembly process is optimized. First, it significantly improves the ease of assembly; second, it greatly facilitates later maintenance and wiring. The independent inspection port and cover plate design allows for the inspection of the controller, clutch mechanism, etc. without disassembling the whole machine, which greatly reduces maintenance costs and time.
