Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and in particular to a modular quick-installation structure for the actuator of an electric damper. Background Technology

[0002] Currently, the dampers of the main ventilation fans on the surface of coal mines are all driven by electric valve actuators. These actuators have electric switching capabilities, allowing the dampers to be controlled locally or remotely.

[0003] In operation, airlocks typically use one or two sets of electric actuators (or simply actuators) to drive the airlock from one side. The mine environment is complex, and the actuators themselves are also complex in structure. If the actuators, reducers, and other components are assembled in the mine, the lack of installation tools and limitations imposed by the installation environment can easily lead to assembly errors, rendering the actuators unusable. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the technical problem of difficult assembly of the actuator in the mine in the prior art, this utility model provides a modular quick-assembly structure for the actuator of the electric air door, which simplifies the assembly difficulty of the actuator in the mine, and ensures the assembly accuracy through modularization, so as to ensure that the actuator can be used normally.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a modular quick-installation structure for the actuator of an electric damper, comprising: a first mounting base plate and a second mounting base plate; a first actuator, the first actuator being mounted on a first connecting plate, the first connecting plate being height-adjustable and mounted on the first mounting base plate; a second actuator, the second actuator being mounted on a second connecting plate, the second connecting plate being height-adjustable and mounted on the second mounting base plate; a reducer, the reducer being mounted on a third connecting plate, the third connecting plate being height-adjustable and mounted on either the first mounting base plate or the second mounting base plate; the reducer is connected to any actuator to form a module, and then the reducer is connected to another actuator.

[0006] The modular quick-assembly structure of the actuator of the electric damper of this utility model allows the reducer and any actuator to be modularly assembled and transported before the actuator leaves the factory. It can then be quickly assembled with another actuator inside the mine, reducing the assembly difficulty in the mine and making it easier to ensure assembly accuracy.

[0007] Furthermore, in order to achieve rapid assembly of the actuator, the first connecting plate and the second connecting plate are provided with multiple mounting brackets, and the first actuator and the second actuator are mounted on the mounting brackets.

[0008] Furthermore, in order to ensure the installation accuracy of the actuators, both the first and second actuators include a power input shaft and a power output shaft, which are rotatably connected to the mounting bracket and are coaxially arranged.

[0009] Furthermore, in order to install the actuator, the power input shaft and the power output shaft are connected by a clutch assembly, which includes a first clutch and a second clutch. The second clutch engages with a gear shaft, and the gear shaft is connected to a switching electric device. The power input shaft is also connected to an active electric device. The active electric device and the switching electric device are mounted on a mounting bracket.

[0010] Furthermore, in order to form a modular structure, the power input shaft, power output shaft, clutch assembly, gear shaft, active electric device, and switching electric device are connected by connecting plates and mounting brackets to form a modular actuator.

[0011] Furthermore, in order to achieve accurate assembly of the reducer and the actuator, the reducer includes a first drive shaft and a second drive shaft. The first drive shaft is provided with a first gear, and the second drive shaft is provided with a second gear. The first gear and the second gear mesh. The height of the third connecting plate is adjusted so that the first drive shaft and the second drive shaft are coaxially connected and assembled with the power output shafts of the two modular actuators respectively.

[0012] Furthermore, for the purpose of installing the speed reducer, a speed reducer is also included, which is mounted on the mounting bracket of the fourth connecting plate, and the fourth connecting plate is mounted on the first mounting base plate with adjustable height.

[0013] Furthermore, in order to connect the reducer and the gearbox, the reducer adjusts its installation height via a fourth connecting plate so that its input shaft is coaxial with the first transmission shaft before docking and assembly.

[0014] Furthermore, in order to adjust the height during installation, the first connecting plate is connected to the first mounting base plate via a shim block, the second connecting plate is connected to the second mounting base plate via a shim block, the third connecting plate is connected to either the first or second mounting base plate via a shim block, and the fourth connecting plate is connected to the first mounting base plate via a shim block.

[0015] Furthermore, in order to achieve a modular structure, the mounting bracket is integrated with the first connecting plate, the second connecting plate, the third connecting plate, or the fourth connecting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The modular quick-assembly structure of the actuator of the electric air door of this utility model allows the actuator and reducer to be modularly assembled and transported to the mine.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1 and Figure 2 As shown, an electric damper actuator includes: a first actuator 1, a second actuator 2, and a reducer 3. The first actuator 1 or the second actuator 2 inputs power to the reducer 3. The reducer 3 transmits the power to the damper 5 through a speed reducer 4, thereby driving the movement of the damper 5.

[0033] Preferably, the first actuator 1 is mounted on the first connecting plate 51, which is height-adjustable on the first mounting base plate 5. The second actuator 2 is mounted on the second connecting plate 61, which is height-adjustable on the second mounting base plate 6. The reducer 3 is mounted on the third connecting plate 52, which is height-adjustable on either the first mounting base plate 5 or the second mounting base plate 6. The first actuator 1 forms a modular structure via the first connecting plate 51 and the first mounting base plate 5; the second actuator 2 forms a modular structure via the second connecting plate 61 and the second mounting base plate 6; and the reducer 3 forms a modular structure with the third connecting plate 52. During factory assembly, the third connecting plate 52 is mounted on the first mounting base plate 5, and then the reducer 3 is connected to the first actuator 1, forming a modular structure of the reducer 3 and the first actuator 1. After transporting the above components into the mine, the second actuator 2 and the reducer 3 are then assembled to complete the assembly of the actuator.

[0034] Specifically, the reducer 3 includes a first drive shaft 31 and a second drive shaft 32. The power of the first actuator 1 is transmitted to the damper 5 through the first drive shaft 31, and the power of the second actuator 2 is transmitted to the damper 5 in sequence through the second drive shaft 32 and the first drive shaft 31.

[0035] Preferably, the reducer 3 is a bevel gear reducer. Specifically, the first drive shaft 31 has a first bevel gear 33, and the second drive shaft 32 has a second bevel gear 34. The first bevel gear 33 and the second bevel gear 34 mesh. The first drive shaft 31 is connected to the power output shaft 12 of the first actuator 1, and the second drive shaft 32 is connected to the power output shaft 12 of the second actuator 2.

[0036] Preferably, both the first actuator 1 and the second actuator 2 include a power input shaft 11 and a power output shaft 12. The power from the power input shaft 11 is selectively transmitted to the power output shaft 12 via a clutch assembly 13. The clutch assembly 13 serves to transmit or disconnect power. The power input shaft 11 is connected to the active electric device 14.

[0037] Preferably, the clutch assembly 13 includes a first clutch 131 and a second clutch 132. An elastic element 133 is connected to the first clutch 131, which is connected to the power output shaft 12 via an involute spline and is movable horizontally relative to the power output shaft 12. The second clutch 132 is connected to the power input shaft 11 via an involute spline and is movable horizontally relative to the power input shaft 11. The opposing end faces of the first clutch 131 and the second clutch 132 have mating engagement portions 134. After the end faces of the first clutch 131 and the second clutch 132 engage, the power from the power input shaft 11 is transmitted to the power output shaft 12 through the second clutch 132 and the first clutch 131, enabling the rotation of the power output shaft 12. When the end faces of the first clutch 131 and the second clutch 132 separate, there is no power transmission between the power output shaft 12 and the power input shaft 11.

[0038] Specifically, the engagement part 134 includes at least two jaws 1341 and a groove 1342. When the jaws 1341 are engaged with the grooves 1342, the first clutch 131 and the second clutch 132 are engaged. In this embodiment, a two-jaw clutch is used, but a three-jaw or four-jaw clutch can achieve the same function.

[0039] The second clutch 132 is perpendicular to the gear shaft. The second clutch 132 has circumferential teeth that mesh with the gear shaft. Rotation of the gear shaft drives the second clutch 132 to translate. The gear shaft is connected to a switching electric device 15. The switching electric device 15 drives the gear to rotate, and the rotation of the gear shaft causes the second clutch 132 to translate. Because the tooth profiles of the gear shaft and the second clutch 132 are perpendicular, the rotation of the second clutch 132 does not affect the gear shaft.

[0040] Specifically, since the mounting bracket and the first connecting plate 51 are integrated, the assembly of the power input shaft, power output shaft, clutch assembly, switching electric device, and active electric device can be completed directly, allowing for rapid modular assembly. After the actuator assembly is completed, the first connecting plate 51 is directly installed on the first mounting base plate 5, and then the third connecting plate 52, which houses the reducer 3, is installed on the first mounting base plate 5. The heights of the first connecting plate 51 and the second connecting plate 61 are then adjusted using shims to ensure coaxial assembly of the first drive shaft and the power output shaft, quickly completing the modular assembly of the first actuator 1 and the reducer 3. Similarly, the second actuator 2 can be assembled onto the second mounting base plate 6 following the same process. The modularly assembled first actuator 1, reducer 3, and second actuator 2 are then transported to the bottom of the mine. At the bottom of the mine, the second actuator 2 is connected to the reducer 3, completing the installation of the actuator. The actuator assembly can be completed underground without complex installation procedures.

[0041] Example 2, as Figure 3 As shown, preferably, the reducer 4 is mounted on the mounting bracket of the fourth connecting plate 53, and the fourth connecting plate 53 is mounted on the first mounting base plate 5 with adjustable height. Similarly, after the above components are installed, the reducer 4 can be reinstalled on the first mounting base plate 5. The installation process is the same as above and will not be described again here.

[0042] In summary, the modular quick-assembly structure of the actuator of the electric damper of this utility model simplifies the assembly difficulty of the actuator in the mine, and ensures assembly accuracy through modularization, thus ensuring that the actuator can be used normally.

[0043] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
