DETAILED DESCRIPTION

[0024] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

The mounting plate 201 is fixed on the inner ring 1, and the rotating wheel 202 is rotatably mounted on the mounting plate 201 through a mounting member. A cap head track 501 for the rotating wheel 202 to be rotatably connected is installed on the inner side of the outer ring 5 of the two-wing revolving door;

[0026] like Figure 1 , Figure 8 , Figure 3 as well as Figure 6 As shown, the driving assembly 3, which is in multiple groups, is fixedly connected to the corresponding wheel assembly 2, and includes a rotary power member and a mounting bracket 302. The mounting bracket 302 is fixedly mounted on the side of the corresponding mounting plate 201 away from the rotating wheel 202. The mounting bracket 302 is provided with a placement cavity for the rotary power member to be mounted therein, and the output shaft of the rotary power member is connected to the rotary shaft of the corresponding rotating wheel 202 through a first connecting member.

[0027] like Figure 1 , Figure 8 , Figure 4As shown in FIG. 7 , the brake assembly 4 is a plurality of groups, which are fixedly connected to the corresponding wheel assembly 2, and includes a clutch and an encoder. The clutch is fixedly connected to the corresponding mounting plate 201 through a plurality of groups of fixing members. The encoder is fixedly mounted on one end of the clutch. The transmission shaft of the clutch is transmission-connected to the rotary shaft of the corresponding rotating wheel 202 through a second connecting member. The plurality of groups of encoders are controlled by a control module to perform synchronous braking on the plurality of groups of clutches.

[0028] Specifically, in the present invention, the preferred number of the wheel assembly 2 is eight groups, and the eight groups of wheel assembly 2 are evenly arranged along the circumference of the two-wing revolving door, wherein two groups of wheel assembly 2 are equipped with driving assemblies 3, and the two groups of driving assemblies 3 drive the corresponding two groups of wheel assembly 2 to rotate, thereby realizing the synchronous rotation of the eight groups of wheel assembly 2, and at the same time, the two groups of wheel assembly 2 equipped with driving assemblies 3 are symmetrical along the center of the two-wing revolving door, and at the same time, two groups of wheel assembly 2 are equipped with braking assemblies 4, and the two groups of braking assemblies 4 realize the braking of the corresponding two groups of wheel assembly 2, thereby realizing the synchronous braking and stopping of the eight groups of wheel assembly 2, and at the same time, the two groups of wheel assembly 2 equipped with braking assemblies 4 are symmetrical along the center of the two-wing revolving door, and the eight groups of wheel assembly 2 maintain force balance when supporting, thereby reducing the wear of the wheel assembly 2;

[0029] Furthermore, the multiple groups of clutches are preferably electromagnetic clutches 401, and the encoders are preferably photoelectric encoders 402. The fixed part of the electromagnetic clutch 401 is connected and fixed to the mounting plate 201. The running speed of the wheel 202 is transmitted to the photoelectric encoder 402 through the rotating shaft. The photoelectric encoder 402 transmits the running speed data to the program controller to control the door body to rotate at a uniform speed. When the emergency stop or stop switch is pressed, the braking device of the electromagnetic clutch 401 clamps the rotating shaft of the corresponding wheel 202, and the operation stops.

[0030] like Figure 5 As shown, in the embodiment of the utility model, the mounting member is a front wheel seat 203 , the rotary shaft of the rotating wheel 202 is rotatably mounted in a mounting hole in the front wheel seat 203 , and the front wheel seat 203 is fixedly mounted on the mounting plate 201 via a round nut 204 .

[0031] like Figure 6 As shown, in the embodiment of the utility model, the rotary power component is a stepper motor 301. Of course, in actual design, other components with rotary driving power can also replace the preferred stepper motor 301 of the utility model, such as a gear driving power structure, etc.

[0032] like Figure 6As shown, in the embodiment of the utility model, the first connecting member is a coupling 303, and the output shaft of the stepper motor 301 is fixedly connected to the rotating shaft of the corresponding rotating wheel 202 through the coupling 303. The coupling 303 has mounting grooves on both sides for connecting the output shaft and the rotating shaft.

[0035] Specifically, when the utility model is used:

[0036] When the working state is controlled, two sets of driving components 3, two sets of braking components 4, and eight sets of wheel assembly components 2 are installed and fixed on the corresponding mounting holes of the turntable of the inner ring 1. When the power is turned on, the motor starts to rotate after the start sensor detection signal is input. The power of the two sets of stepper motors 301 is transmitted to the rotating wheel 202 through the coupling 303 and the rotating shaft. The rotation of the rotating wheel 202 of the driving component 3 drives the remaining six sets of wheel assembly components to rotate counterclockwise at a uniform speed around the center of the circle on the cap head track 501 of the outer ring 5. The turntable rotates together with the weight of the rotating wing and the door body;

[0037] When the stop state is controlled, after the stop switch is pressed or a stop signal such as anti-pinch is detected, the motor stops running immediately. At the same time, the electromagnetic clutch 401 on the brake assembly 4 enters the braking mode immediately after receiving the stop signal, and the rotation stops.

[0038] In summary, in the utility model, multiple groups of wheel assemblies 2 of the same specification are preferably provided, and the corresponding drive assemblies 3 and brake assemblies 4 are installed to realize the rotation operation or stop of the two-wing revolving door, so that the wheel assemblies 2 do not need to be customized separately according to the function, which solves the problem that the existing two-wing revolving door driving wheel mechanism has a complex structure, and its driving wheel, brake wheel, and driven wheel adopt individually customized design components, with many types of parts processing, great difficulty in assembly, and high cost. At the same time, eight groups of wheel assemblies 2 are evenly arranged along the circumference of the two-wing revolving door, two groups of wheel assemblies 2 are equipped with drive assemblies 3, and the two groups of wheel assemblies 2 equipped with drive assemblies 3 are symmetrical along the center of the two-wing revolving door, two groups of wheel assemblies 2 are equipped with brake assemblies 4, and the two groups of wheel assemblies 2 equipped with brake assemblies 4 are symmetrical along the center of the two-wing revolving door, and the eight groups of wheel assemblies 2 maintain force balance when supporting, thereby reducing the wear of the wheel assemblies 2.
