Applicants have discovered in the course of practicing the present disclosure that: automatic revolving doors on the market are mostly two-wing, three-wing and four-wing automatic revolving doors.

For the two-wing automatic revolving door, as shown in fig. 1 and 2, the driving form is edge driving, that is, a track 300 is arranged around the upper part of the revolving door body, the track 300 is supported by a plurality of upright posts 202 (generally 6-8) fixed on the fixed door body 200, referring to fig. 7, a plurality of wheels 600 matched with the track 300 are arranged on the top of the revolving door body 100, wherein 2 wheels 600 are driving wheels driven by a driving mechanism, and the rest wheels 600 are driven wheels; the driving mechanism drives the driving wheel to rotate and then drives the driven wheel to rotate, and accordingly, the rotating door body 100 rotates relative to the fixed door body 200 to achieve opening and closing of the rotating door.

For three-wing and four-wing automatic revolving doors, the driving form is central driving, which is further divided into upper rotating central driving (as shown in fig. 3 and 4) and lower rotating central driving (as shown in fig. 5 and 6), i.e. a driving mechanism (such as a driving motor 500) is arranged above or below the central position of the revolving door body 100, and the central output shaft of the driving mechanism directly drives the revolving door body 100 to rotate, so that the revolving door body 100 rotates around the output shaft, thereby realizing the opening and closing of the revolving door.

The driving modes are different, and the driving modes are mainly caused by the difference between the structure of the rotary door body 100 of the three-wing automatic revolving door and the structure of the rotary door body 100 of the two-wing automatic revolving door, the rotary door body 100 of the two-wing automatic revolving door comprises two opposite rotary door leaves 101 as shown in fig. 1 and fig. 2, and a vertical hinged door 800 is generally arranged between the two rotary door leaves 101 to play a role in guiding flow in emergency situations; the center drive cannot be selected because the vertical hinged door 800 is provided in the middle. The structure of the revolving door leaf 101 of the three-wing and four-wing automatic revolving door is as shown in fig. 3-6, and the principle of the central driving form is simple and easy to realize, therefore, the three-wing and four-wing automatic revolving door all use the central driving form at present.

And, because of receiving the influence of the inherent thinking of the current "revolving door that people followed the door and walk", the revolving door is rotatory relatively ground, leave the gap between revolving door and ground, consequently, current two wings automatic revolving door is the rotatory edge drive in last, wheel 600 is located the upper portion edge of the revolving door body 100 promptly, and bear the weight of whole revolving door body 100 by the track 300 that is in revolving door body 100 upper portion edge equally, the edge drive of this form has higher requirements for the intensity of track 300 and stand 202, make the maintenance cost of revolving door higher, and actuating mechanism also is located the top of the revolving door body 100, be unfavorable for staff to actuating mechanism's installation and maintenance.

Because the edge drive has obvious braking advantage compared with the central drive, the edge drive is expanded from the two-wing automatic revolving door to the three-wing and four-wing automatic revolving door, and the edge drive can be expanded into an upper rotating type or a lower rotating type, so that the application range of the edge drive in the field of automatic revolving doors is expanded.

Moreover, the turntable, the track 300 and the driving mechanism can be all positioned in the geosyncline 900, so that the ground space is saved, and the installation and maintenance of the driving mechanism by workers are facilitated.

In some embodiments, for various types of revolving doors, when a plurality of wheels 600 are located above the revolving door body 100 (i.e. upper revolving edge driving), referring to fig. 7, the wheels 600 are connected with the upper edge of the revolving door leaf 101 through wheel fixing brackets 601 to realize the rotation of the revolving door body 100 together with the revolving door body relative to the track 300. The track 300 is located on the upright 202 of the fixed door leaf 201, as shown in fig. 7.

Because the existing two-wing automatic revolving door is in this form, it is not described again, and the existing three-wing and four-wing automatic revolving door can also adopt this form, for example, at least one wheel 600 is installed on the upper edge of each revolving door leaf 101 of the three-wing and four-wing automatic revolving door, and the track 300 is arranged on the upright 202 of the fixed door leaf 201.

In some embodiments, for various types of revolving doors, when a plurality of wheels 600 are located above the revolving door body 100 (i.e., an upper revolving edge drive), the supporting frame 400 is located above the revolving door body 100 and is fixed in position relative to the revolving door body 100, and the supporting frame 400 is configured to cooperate with the track 300 through the wheels 600 to realize that it rotates together with the revolving door body 100 relative to the track 300. The track 300 is located on the pillar 202 of the fixed door leaf 201, as shown in fig. 16, that is, only the adaptive structure is changed (for example, the supporting frame 400 is provided), the matching form of the wheel 600 and the track 300 of the existing two-wing automatic revolving door is still used, and the transformation is easily performed on the basis of the existing three-wing automatic revolving door and four-wing automatic revolving door.

In this embodiment, the supporting frame 400 and the wheels 600 form a rotary table for driving the rotary door body 100 to rotate, and the rotary door body 100 and the rotary table rotate together relative to the ground, thereby implementing the upper rotary edge driving of the automatic revolving door.

In some embodiments, the edge drive format is as follows for various styles of turnstiles: a part of the wheels 600 in the plurality of wheels 600 are configured to drive the swing door body 100 to rotate above the swing door body 100, and the rest of the wheels 600 are configured to drive the swing door body 100 to rotate below the swing door body 100; that is, a portion of the wheels 600 among the plurality of wheels 600 is located above the rotary door body 100, and the remaining portion of the wheels 600 is located below the rotary door body 100, in other words, a hybrid edge drive in which an upper rotary edge drive is combined with a lower rotary edge drive.

Referring to the implementation forms of the upper rotary edge drive and the lower rotary edge drive in the above embodiments, referring to fig. 15 and 16, that is, the lower rotary edge drive may be implemented by disposing the supporting frame 400 and/or the floor 700, the wheels 600 and the rails 300 under the rotary door body 100; the upper rotary edge drive is realized by arranging the support frame 400, the wheels 600 and the tracks 300 above the rotary door body 100; alternatively, wheels 600 are provided directly at the upper edge of each of the swing door leaves 101 to realize the upper swing edge drive.

In some embodiments, the wheel 600 shown in fig. 7 is generally selected for the conventional two-wing automatic revolving door because the installation space of the wheel 600 is limited, that is, the wheel 600 is located at one side of the wheel fixing bracket 601, the pressure of the wheel 600 on the track 300 is not uniform, and the wheel 600 and the track 300 are easily deformed during long-term use. In the present disclosure, if there is also a problem that the installation space is limited for the upper rotary edge-driven three-wing or four-wing automatic revolving door, the wheels 600 as shown in fig. 7 may be used; for the two-wing, three-wing and four-wing automatic revolving door driven by the lower revolving edge, the wheel 600 has a larger installation space due to the change of the driving form, the wheel 600 can be selected as shown in fig. 17, the wheel 600 is located in the wheel fixing bracket 601, further alternatively, the wheel 600 is located in the middle of the wheel fixing bracket 601, the fixing bracket is located at the edge of the supporting frame 400, and the pressure of the wheel 600 on the track 300 is more uniform and reasonable.

The present disclosure expands the application range of the edge drive in the two-wing, three-wing, and four-wing automatic revolving doors because the braking distance of the edge drive is smaller than that of the center drive, and in addition, searches for how to further reduce the braking distance of the edge drive.

Referring to the requirements of 6.5.1 and 6.9.2 in JG/T177-2005, the running speed of the automatic revolving door is less than or equal to 0.75m/s, and the braking distance of the automatic revolving door is 200-250 mm, however, the requirement of the braking distance has a very large potential safety hazard in use and is usually adjusted to the range of 140-180 mm; in addition, taking the conventional two-wing automatic revolving door as an example, referring to fig. 8, compared to two-wing automatic revolving doors with different volumes, generally, 6 to 12 wheels 600 are provided for edge driving, wherein only two wheels 600 are driving wheels driven by a driving mechanism, and the rest wheels 600 are driven wheels.

According to the relevant formulas of kinematics and momentum theorem:

v at, S Vt +0.5at2, F ma and mV Ft,

wherein, V: the running speed of the equipment; s: a braking distance; t: a braking time; f, braking force; m: rotating part equipment mass a: braking acceleration;

it can be derived that: braking force F is 1.5V²m/S(I)。

The following analysis can be performed from formula (I): when the running speed of the revolving door is constant, the braking force is in direct proportion to the mass of equipment and in inverse proportion to the braking distance, namely, under the condition that the mass of the revolving door is constant, if the braking distance is adjusted to be reduced to the range of 140-180 mm, the output of the braking force needs to be increased, the output of the braking force is mainly determined by the power of the driving mechanism, the higher the power is, the larger the braking force can be output, the existing two-wing automatic revolving door is taken as an example, the damage to the two driving mechanisms (such as the driving motor) is serious because the commonly used braking output power is higher, the maintenance cost is higher, and the normal use of the revolving door can be influenced even.

In addition, the design of the revolving door cannot only consider how the equipment normally operates and brakes, but also consider that the impact force of the revolving door body 100 to personnel is minimum when a safety accident occurs, and in order to improve the driving safety of the automatic revolving door, an infrared sensor is generally arranged at the upper part of the revolving door to brake when an emergency occurs. However, in the operation process of the automatic revolving door, due to the reasons of large weight, large inertia, large torque and the like of the revolving door body 100, the braking distance of the equipment is long, and both the impact force and the clamping force are large, so that personal injury is caused. For this reason, it is generally preferable to set the output power of the driving mechanism to 1.05 to 1.1 times of the power to overcome the resistance (the resistance to overcome is mainly the wind pressure when the apparatus operates and the rolling friction force when the wheels 600 operate on the track 300); take a two-wing automatic revolving door with a diameter of 4200mm as an example (the following values are predicted): the mass m of the rotating door body 100 is 800-1000 KG (the value is obtained according to the intermediate value during calculation), the rolling friction coefficient is mu 0.03-0.05 (the value is obtained according to the intermediate value during calculation), and the running speed V of the equipment is 0.7 m/s.

The theoretical output power of the equipment operation is as follows: w ═ F × V ═ m × g × V ═ 900 × 9.8 × 0.04 × 0.7 ═ 247 watts; the power for ensuring the normal operation of the equipment is as follows: 247 × 1.1 ═ 272 watts;

however, the existing two-wing automatic revolving door mainly considers how the equipment normally operates and brakes, and usually 2 motors of 250 watts or 370 watts are installed, the output power of the two motors is 500 watts (taking the installation of 2 motors of 250 watts as an example), which is far greater than 272 watts for ensuring the normal operation of the equipment, and when a safety accident occurs, the impact force to personnel is very large, thus causing the safety accident. And when a safety accident occurs, a larger braking force needs to be provided instantly to ensure the shortest distance to stop the equipment.

And, taking the braking distance as 200mm as an example, F is 1.5V²m/S1.5 0.72 900/0.2 3308 newtons, which places a large load on the two motors. In order to ensure a shorter braking distance, the load on the motor is further increased, and the losses on the motor are also greater.

The motor commonly used in the market at present is a renz servo motor, the model is GST04-2MVBR063C42, P is 0.25KW, I is 11.2, CLP is 460, the motor has large mass and high price, and brings great loss to customers for maintenance and replacement.

In order to solve the above problems, the applicant finds that the arrangement of a plurality of driving wheels driven by driving mechanisms can solve the problem of great damage to the driving mechanisms caused by high braking output power required by two driving mechanisms in the existing edge driving, and can conveniently control the braking distance of the revolving door within the range of 140-180 mm.

To solve the above technical problem, in some embodiments, at least three of the plurality of wheels 600 are driving wheels driven by the driving mechanism to rotate, as shown in fig. 18.

Further, all the wheels 600 are driving wheels driven by the driving mechanism to rotate, as shown in fig. 19.

In this embodiment, only the condition of two action wheels has improved in the edge drive than current, all sets up 3 at least wheels 600 and even all wheels 600 into the action wheel, under the unchangeable condition of guaranteeing overall brake output, reduces every actuating mechanism's power to reduce the damage to actuating mechanism because of the output power height then.

With the increased number of driving mechanisms, a low-power direct current motor can be used for driving, for example: desenke direct current motor, the model is GR53, and is small, adopts 24V voltage, and is safer more convenient.

In some embodiments, a torque sensor 110 is also provided, and referring to fig. 22, the torque sensor 110 is positioned between the drive mechanism and the wheel 600 and is configured to measure the torque output by the drive motor 500 when the swing door is rotated.

Further, the driving mechanism is connected to the torque sensor 110 through a coupling 120, and the torque sensor 110 is connected to the wheel 600 through the coupling 120.

Further, the torque sensor 110 has various options, such as a JN338-A series direct-connected torque sensor, and the like.

As described above, in consideration of how the equipment is normally operated, braking, and the impact force of the rotary door body 100 to a person is minimized when a safety accident occurs, it is generally preferable to set the output power of the driving mechanism to be 1.05 to 1.1 times the power against the resistance. The output power of the driving mechanism needs to be monitored, and in the normal operation process of the equipment, when the torque exceeds a set value, an alarm can be given or the operation can be stopped, so that the revolving door can work in a normal state and the safety of passers-by can be ensured.

The specific operation of the torque sensor 110 is as follows: the frequency signal output by the torque sensor 110 is transmitted to a frequency meter or a digital meter, and the frequency signal or the voltage and current signal which is in direct proportion to the torque is read; the torque and frequency signals of the torque sensor 110 are transmitted to a control system such as a single chip microcomputer, and a real-time torque value, a rotating speed, an output power value and an RS232 communication signal can be directly displayed on a display; transmitting the frequency signals of the torque and the rotating speed to a computer or a PLD (programmable logic device) for processing; when the torque value is detected to exceed the set data, the control system sends a digital signal, the driving system stops driving the motor 500 to operate, and meanwhile, the control system records the information.
