Description

Technical Field

[0001] The invention relates to the technical field of access control motors, in particular to a gapless access control device. Background Art

[0002] With the continuous acceleration of urbanization, the management and control of traffic flow has become increasingly important. As a common traffic management device, barriers are widely used in parking lots, toll booths, airports and other places. Traditional access control devices are usually composed of motors, reducers and rotating rods. During use, the rotating rod is driven to rotate by the motor connected to the reducer to control the lifting and lowering of the barrier.

However, when the traffic volume is large and cars need to pass through the barrier continuously to enter the parking lot, the camera will perform continuous and rapid license plate recognition. However, due to the time difference between vehicles entering, the rotating gate bar of the barrier often needs to slow down and turn up again after just turning down. In this process, the drive motor needs to complete the deceleration and reverse action. The motor drive shaft needs to overcome the large rotational inertia, so there is often a certain rotation gap, which causes the gate bar to get stuck. If the gate bar cannot be lifted in time, it may be knocked down by the vehicle.

DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 11The present invention provides a technical solution: a gapless access control device, comprising a gate chassis 17, a motor installed in the gate chassis 17, and a rotating shaft 19 is installed on the gate chassis 17 through a bearing seat 18, and a limited sliding groove 20 is arranged on the rotating shaft 19, and a connecting slider 4 is slidably arranged in the limited sliding groove 20;

[0037] A base 21 is fixedly mounted on the rotating shaft 19, and a barrier rod 22 is fixedly connected to the base 21. A slide 23 is arranged on the barrier rod 22, and a counterweight iron block 24 is movably installed in the slide 23. Electromagnets and anti-collision blocks 27 that are turned on alternately are arranged at both ends of the slide 23, and pop-up damping structures driven by electromagnetics are arranged at both ends of the slide 23.

[0038] The access control device of the present invention uses a motor that can make up for the rotation gap, so its barrier rod 22 can quickly lift the bar during the downward rotation, and the center of gravity of the barrier rod 22 can also be automatically adjusted to further increase the speed of lifting or lowering the bar.

[0039] The bearing seat 18 is installed on the side wall of the gate chassis 17, and the rotating shaft 19 is arranged horizontally. The limiting slide groove 20 adopts a polygonal slide groove, and the limiting slide groove 20 is arranged on the inner end surface of the rotating shaft 19, and the base 21 is connected to the outer end of the rotating shaft 19.

[0040] In the access control device, the bearing seat 18 is used to install the rotating shaft 19, and the rotating shaft 19 is connected to the auxiliary output shaft 3 through the limiting slide groove 20, so that the auxiliary output shaft 3 maintains the drive of the rotating shaft 19 during the movement, and can drive the base 21 to rotate up and down.

[0041] The barrier rod 22 is assembled on the base 21 by a bolt assembly, and the slideway 23 is installed on the back of the barrier rod 22 , and the counterweight iron block 24 is limitedly slidably arranged in the inner slide groove of the slideway 23 .

[0042] The barrier rod 22 can rotate with the base 21, and the counterweight iron block 24 is installed on the barrier rod 22 of the present invention through the slide 23. The counterweight iron block 24 can slide in the slide 23 to achieve the effect of adjusting the overall center of gravity of the barrier rod 22.

[0043] An end electromagnet 25 is disposed at one end of the slideway 23 close to the base 21 , and a front electromagnet 26 is disposed at one end away from the base 21 , and an anti-collision block 27 is installed in an inner slide groove of the slideway 23 .

[0044] When the end electromagnet 25 is turned on, the counterweight iron block 24 can be attracted toward the end direction of the barrier pole 22, so that the center of gravity of the barrier pole 22 is closer to the base 21. At this time, the barrier pole 22 can be turned up and lifted more quickly by the motor, further improving the lifting speed. When the front electromagnet 26 is turned on, the counterweight iron block 24 is attracted toward the front end direction of the barrier pole 22, so that the center of gravity of the barrier pole 22 is closer to the front end. At this time, the barrier pole 22 can have a faster lowering speed.

[0045] The damping structure includes a damping plate 28 which is slidably mounted on the side wall of the slide 23 with a limited position, and a slope 29 is arranged on the outer end surface of the damping plate 28, a side seat 30 is installed on the outer wall of the slide 23, and a movable pressure piece 31 is slidably mounted in the side seat 30, and the front end of the movable pressure piece 31 is in contact with and connected to the slope 29, and an iron end block 32 is arranged at the end of the movable pressure piece 31, and a spring 33 is connected to the iron end block 32.

[0046] In addition to limiting the counterweight iron block 24 by means of the anti-collision block 27, a damping structure is also provided at both ends of the slide 23. When the electromagnet near the damping structure is turned on, the iron end block 32 can be attracted, so that the movable pressure piece 31 is pressed on the slope 29, and then the damping plate 28 is pressed inward, compressing the inner space of the slide 23, contacting the counterweight iron block 24 to slow down when it is close to the end of the slide 23, and stably falling on the anti-collision block 27. When the position of the counterweight iron block 24 needs to be adjusted again, the damping structure can automatically fail due to the closure of the electromagnet on this side, so that the counterweight iron block 24 can be smoothly detached.

[0047] The motor capable of compensating the rotation gap comprises a motor body 1, on which a motor shaft is rotatably mounted, the motor shaft consisting of a main output shaft 2 and a secondary output shaft 3, both the main output shaft 2 and the secondary output shaft 3 are provided with a docking joint 5, and a connecting slider 4 is fixedly connected to the secondary output shaft 3;

[0048] The auxiliary output shaft 3 is rotatably mounted on the mounting seat 6, and the mounting seat 6 is movably mounted in the motor body 1, and the position control of the mounting seat 6 is controlled by the pushing cylinder 9, an auxiliary shaft 11 is rotatably mounted on the mounting seat 6, a main gear 12 is fixedly mounted on the main output shaft 2, and a auxiliary gear 13 is fixedly mounted on the auxiliary shaft 11, and the auxiliary output shaft 3 and the auxiliary shaft 11 are transmission connected via a pulley transmission pair.

[0049] The motor of the present invention is specially used in a door access control device, and can directly turn the gate pole without decelerating and reversing the motor, thereby making up for the gap in the rotation of the gate pole, so that the gate pole can be quickly turned and lifted to avoid being hit by a vehicle.

[0050] The motor body 1 is composed of a driving motor and a reducer, and the motor shaft is arranged horizontally, the main output shaft 2 and the auxiliary output shaft 3 are arranged coaxially, and a bite key is arranged on the docking joint 5, and the docking joints 5 on the main output shaft 2 and the auxiliary output shaft 3 are arranged opposite to each other, and the connecting slider 4 adopts a polyhedron structure, and the connecting slider 4 is installed at the end of the auxiliary output shaft 3.

[0051] The motor of the present invention divides the motor shaft into two parts. The main output shaft 2 is directly connected to the motor body 1, and the auxiliary output shaft 3 has two states of being connected or disconnected from the main output shaft 2. Therefore, the motor has two modes of direct drive and direction-changing drive for the barrier pole. When the main output shaft 2 and the auxiliary output shaft 3 are connected together through the docking joint 5, the two rotate in the same direction, which is a direct drive mode, and can make the barrier pole turn down normally. When the vehicle enters the barrier immediately afterwards, if the barrier needs to be lifted up as soon as it starts to fall, the main output shaft 2 and the auxiliary output shaft 3 are disconnected and enter the direction-changing drive mode, so that the direction of the motor remains unchanged, while the rotation direction of the auxiliary output shaft 3 changes, driving the barrier pole to turn up quickly, eliminating the process of motor deceleration and steering. Finally, after the barrier pole is lifted to the limit position, the auxiliary output shaft 3 can be restored to the state of being connected to the main output shaft 2 and driven normally.

[0052] A base 7 is fixedly mounted on the motor body 1 , and a guide member 8 is slidably mounted on the base 7 . The mounting seat 6 is arranged on the guide member 8 , and a connecting member 10 is fixedly mounted on the guide member 8 , pushing the cylinder 9 to connect with the connecting member 10 .

[0053] The connection and separation of the auxiliary output shaft 3 and the main output shaft 2 are completed by moving the mounting seat 6. By pushing the cylinder 9 to push the guide member 8, the mounting seat 6 can be moved closer to or away from the base 7. When the mounting seat 6 is close, the auxiliary output shaft 3 and the main output shaft 2 are connected together. Conversely, when the mounting seat 6 is moved away, the auxiliary output shaft 3 and the main output shaft 2 are separated.

[0054] The auxiliary shaft 11 and the auxiliary output shaft 3 are installed side by side in the mounting seat 6, and the main gear 12 and the auxiliary gear 13 have two states: meshing and disengaging.

[0055] When the auxiliary output shaft 3 and the main output shaft 2 are disengaged, the auxiliary gear 13 will move toward the main gear 12. During the rotation of the main gear 12, the auxiliary gear 13 can complete the process of meshing with it, thereby driving the auxiliary shaft 11 to rotate in the opposite direction through the main output shaft 2.

[0056] The pulley transmission pair includes a first pulley 14 fixedly mounted on the secondary output shaft 3 and a second pulley 15 fixedly mounted on the auxiliary shaft 11 , and the first pulley 14 and the second pulley 15 are connected by a belt 16 .

[0057] The auxiliary shaft 11 and the auxiliary output shaft 3 are connected through a pulley transmission pair, and the two rotate in the same direction. Therefore, when the main output shaft 2 drives the auxiliary shaft 11, the auxiliary output shaft 3 rotates in the opposite direction to the main output shaft 2, thereby achieving the effect of reverse driving the gate rod.

[0058] When the motor of the present invention is in use: first, the motor of the present invention divides the motor shaft into two parts, the main output shaft 2 is directly connected to the motor body 1, and the auxiliary output shaft 3 has two states of being connected or disconnected from the main output shaft 2, so that the motor has two modes of direct drive and direction-changing drive for the barrier pole. When the main output shaft 2 and the auxiliary output shaft 3 are connected together through the docking joint 5, the two rotate in the same direction, which is a direct drive mode, and can make the barrier pole turn down normally. When the vehicle enters the barrier immediately afterwards, if the barrier needs to be lifted up as soon as it starts to fall, the main output shaft 2 and the auxiliary output shaft 3 are disconnected, and enter the direction-changing drive mode, so that the direction of the motor remains unchanged, while the rotation direction of the auxiliary output shaft 3 changes, driving the barrier pole to turn up quickly, eliminating the process of motor deceleration and steering, and finally, after the barrier pole is lifted to the limit position, the auxiliary output shaft 3 can be restored to the state of being connected to the main output shaft 2, and driven normally. The connection and separation of the auxiliary output shaft 3 and the main output shaft 2 are completed by the movement of the mounting seat 6. By pushing the cylinder 9 to push the guide member 8, the mounting seat 6 can be moved close to or away from the base 7. When the mounting seat 6 is close, the auxiliary output shaft 3 and the main output shaft 2 are connected together. On the contrary, when the mounting seat 6 is away, the auxiliary output shaft 3 and the main output shaft 2 are separated. When the auxiliary output shaft 3 and the main output shaft 2 are separated, the auxiliary gear 13 will move in the direction of the main gear 12. During the rotation of the main gear 12, the auxiliary gear 13 can complete the process of meshing with it, thereby driving the auxiliary shaft 11 to rotate in the opposite direction through the main output shaft 2. The auxiliary shaft 11 and the auxiliary output shaft 3 are connected by a pulley transmission pair, and the two are in a co-directional rotation relationship. Therefore, when the main output shaft 2 drives the auxiliary shaft 11, the auxiliary output shaft 3 and the main output shaft 2 rotate in the opposite direction, thereby achieving the effect of reverse driving the gate rod;

[0059] When the access control device using the motor is in use: first, in the access control device, the bearing seat 18 is used to install the rotating shaft 19, and the rotating shaft 19 is connected to the auxiliary output shaft 3 through the limiting slide groove 20, so that the auxiliary output shaft 3 maintains the driving of the rotating shaft 19 during the movement, and can drive the base 21 to rotate up and down, and the gate rod 22 can rotate with the base 21, and the gate rod 22 of the present invention is installed with a counterweight iron block 24 through a slideway 23, and the counterweight iron block 24 can slide in the slideway 23 to achieve the effect of adjusting the overall center of gravity of the gate rod 22. When the end electromagnet 25 is turned on, the counterweight iron block 24 can be attracted toward the end direction of the gate rod 22, so that the center of gravity of the gate rod 22 is closer to the base 21. At this time, the motor can more quickly turn and lift the gate rod 22, further improving the lifting speed. When the front electromagnet 26 is turned on, the counterweight iron block 24 is attracted toward the front end direction of the gate rod 22, so that the center of gravity of the gate rod 22 is closer to the front end. At this time, the gate rod 22 can have a faster falling speed. In addition to limiting the counterweight iron block 24 by the anti-collision block 27, a damping structure is also provided at both ends of the slide 23. When the electromagnet close to the damping structure is turned on, the iron end block 32 can be attracted, so that the movable pressing piece 31 is pressed on the slope 29, and then the damping plate 28 is pressed inwardly, the inner space of the slide 23 is compressed, and the counterweight iron block 24 is contacted to slow down when it is close to the end of the slide 23, and stably falls on the anti-collision block 27. When the position of the counterweight iron block 24 needs to be adjusted again, the electromagnet on this side is closed, and the damping structure can automatically fail, so that the counterweight iron block 24 can be smoothly separated.

[0060] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
