Description

Technical Field

[0001] The present invention relates to the technical field of barrier gate equipment, in particular to an electric automated barrier gate. Background Art

[0002] Barriers are usually set at the entrance and exit of a passage to manage the vehicles entering and leaving the passage.

[0003] The barrier gate relies on electricity to drive its mechanical device. Once the power is cut off, the entire barrier gate system will not be able to operate normally, resulting in an inability to open or close. This will cause trouble for vehicle traffic, especially during peak hours, which may cause traffic congestion and affect the normal order of the parking lot. At the same time, it will cause a negative reputation impact on the affiliated business units (such as hospitals, shopping malls, supermarkets, etc.). In view of this, at the first moment of power outage, the person in charge needs to arrive at the scene quickly and manually lift the bar to prevent vehicles and personnel in the field from being trapped. However, when the barrier gate is cut off due to bad weather (such as strong winds), the raised interception bar is easy to bend or break, and the internal components of the barrier gate connected to the interception bar are also easily damaged;

[0004] At the same time, if the vehicle is following closely, the sudden drop of the interception bar may easily cause damage to the vehicle or the people inside the vehicle, causing unnecessary trouble. For this reason, we propose an electrical automatic barrier gate in which the power-off interception bar automatically sinks into the ground, while reducing the damage to vehicles and people during the falling process.

[0023] The present invention has at least the following beneficial effects:

[0024] 1. When the gate body is powered off, the metal weight loses the magnetic force of the electromagnet, and its falling gravity drives the motor to separate from the interception bar under the action of the separation mechanism.

[0025] 2. When the motor is separated from the interception bar, if the interception bar is in the raised state, the resistance increasing plate in the buffer mechanism fits with the interception bar, slowing down the speed of the interception bar rotating and falling, giving the occupants of the vehicle enough time to react and prevent the interception bar from falling instantly and causing damage to the vehicle and personnel;

[0026] 3.

When in use, it can also be opened in time to accommodate the interception rod to prevent the interception rod from being damaged by bad weather;

[0027] 4. Under the action of the telescopic shaft part, the intercepting rod is always in a foldable state before it is completely parallel to the ground to prevent the vehicle from following too closely and causing damage to the vehicle. After it is completely parallel to the ground, the rotating part and the intercepting part are automatically engaged to prevent people from maliciously lifting the rod to leave the site.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, 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 creative work are within the scope of protection of the present invention.

[0043] Example 1

[0044] See also Figure 1-13 The present invention provides a technical solution: an electric automatic gate, comprising a gate body 1 and a motor 11 installed in the gate body 1, the output shaft of the motor 11 passes through the gate body 1, and a polygonal block 12 is installed on the top, the output shaft of the motor 11 is connected to an interception rod 2, the interception rod 2 is provided with a polygonal groove 21, the polygonal block 12 is matched with the polygonal groove 21, and also includes:

[0045] The base 3 is installed on the gate body 1 and pre-buried in the ground. The base 3 is in an "L" shape and has an L groove 31;

[0046] The electromagnet 4 is fixed in the gate body 1 and has a metal weight 41 adsorbed thereon;

[0047] The separation mechanism 5 is installed on the gate body 1 and connected to the motor 11. When the metal weight block 41 falls naturally, the separation mechanism 5 disconnects the contact between the motor 11 and the interception rod 2 and guides the interception rod 2 to fall into the L groove 31;

[0048] The buffer mechanism 6 is mounted on the gate body 1 and connected to the motor 11 and the interception bar 2. The buffer mechanism 6 slows down the speed of the interception bar 2 during its rotation and falling process through the movement of the motor 11;

[0049] A chute 300 is provided on the gate body 1 and has a blocking plate 301 installed therein. The blocking plate 301 blocks the L-groove 31;

[0050] The control mechanism 7 is installed on the gate body 1 and connected to the blocking plate 301. The control mechanism 7 controls the blocking plate 301 to block and open the L slot 31;

[0051] The transmission mechanism 8 is installed on the gate body 1 and is connected to the separation mechanism 5 and the control mechanism 7. The transmission mechanism 8 drives the control mechanism 7 to change the opening and closing of the L-slot 31 by the blocking plate 301 through the falling and rising of the metal weight block 41.

[0052] The separation mechanism 5 includes a slide cylinder 51 fixed on the electromagnet 4, a limit block 52 is fixed in the gate body 1, the limit block 52 blocks the bottom of the slide cylinder 51, a rubber sleeve 53 is sleeved on the outer periphery of the metal weight block 41, a pipe 54 is connected to the slide cylinder 51, and the pipe 54 penetrates the electromagnet 4, a support frame 55 is installed on the gate body 1, and the support frame 55 further supports the motor 11, a piston cylinder 56 is fixed on the support frame 55, and the other end of the pipe 54 is connected to the piston cylinder 56, and a piston rod 5 is fixed on the motor 11. 7. The piston rod 57 penetrates the piston cylinder 56. A slide groove 58 is provided on the slide cylinder 51. There are a plurality of slide grooves 58 arranged in a circular array on the slide cylinder 51. An air hole 59 is provided on the upper part of the slide cylinder 51. The air hole 59 is blocked by a metal weight block 41. The slide cylinder 51 also includes a support plate 510 installed on one side of the gate body 1. A guide rail 511 is relatively installed on the support plate 510 and the gate body 1. One end of the guide rail 511 is arc-shaped. A roller 512 is installed on the intercepting rod 2. There are a plurality of rollers 512, which are all located in the guide rail 511.

[0053] The metal weight block 41 is made of a metal material that can be attracted by a magnet. Under the wrapping of the rubber sleeve 53, a closed space is formed between the metal weight block 41, the upper part of the slide cylinder 51 and the electromagnet 4. When the gate body 1 is suddenly powered off, the magnetic force of the electromagnet 4 is lost. Under the action of gravity, the metal weight block 41 slides down in the slide cylinder 51, and negative pressure is generated between the upper part of the metal weight block 41 and the upper part of the slide cylinder 51. This pressure is transmitted through the pipeline 54, so that a great negative pressure is generated in the piston cylinder 56. Under the action of the negative pressure, the piston rod 57 drives the motor fixedly connected to it. 11 moves synchronously, at this time, the top of the motor 11 is separated from the intercepting rod 2, and the support of the output shaft of the motor 11 is lost. Under the action of the intercepting rod 2's own gravity, the intercepting rod 2 falls along the guide rail 511. Since one end of the guide rail 511 is arc-shaped, the intercepting rod 2 is always located in the guide rail 511, and the intercepting rod 2 can fall even if it is fully raised or half raised. After the motor 11 is completely separated from the intercepting rod 2, the top of the metal weight block 41 just releases the blockage of the air hole 59. At this time, the attraction of the negative pressure is lost, and the metal weight block 41 continues to fall.

[0054] The buffer mechanism 6 includes a wedge plate 61 installed on the gate body 1, one end of the wedge plate 61 is fixed to the gate body 1, and the other end is fixed to the support plate 510. A rod 2 62 is installed through the gate body 1, and the rod 2 62 penetrates the wedge plate 61. A ring 63 is fixed on the rod 2 62, and a fixing frame 64 is connected between the ring 63 and the motor 11. A clamping plate 65 is fixed to the other end of the rod 2 62, and a resistance-enhancing plate 66 is provided on the clamping plate 65.

[0055] When the motor 11 controls the intercepting rod 2 to rise to the highest point, the angle between the intercepting rod 2 and the ground is less than 90°, ensuring that the intercepting rod 2 can continue to fall after losing the support of the motor 11, and the wedge plate 61 further limits the maximum rotatable angle of the intercepting rod 2. When the motor 11 moves, the motor 11 drives the rod 2 62 fixed with the ring 63 through the fixing frame 64 to move synchronously, and the rod 2 62 drives the clamping plate 65 to approach the intercepting rod 2, and the resistance-increasing plate 66 on the clamping plate 65 is fitted with one side of the intercepting rod 2, thereby increasing the resistance encountered by the intercepting rod 2 during the rotation and falling process, slowing down its speed during the rotation and falling process, and giving the people inside the vehicle enough reaction time to respond.

[0056] The control mechanism 7 includes a slide groove 3 71 installed on the gate body 1, and a slider 72 is installed in each of the slide grooves 71. The slide groove 3 71 limits the slider 72 to move only in the slide groove 3 71. A notch 1 73 is provided on the slider 72. A fixing seat 74 is relatively installed on the blocking plate 301. A notch 2 75 is provided on the fixing seat 74. A shaft 1 76 is installed on the notch 1 73 and the notch 2 75. A connecting rod 1 77 is installed between the shaft 1 76. A notch 3 78 is provided on the slider 72. A shaft 2 79 is installed on the notch 3 78. A connecting rod 2 720 is installed on the shaft 2 79. The connecting rod 2 720 is provided with another notch 3 78. A connecting seat 710 is installed at the end, a notch 4 711 is opened on the connecting seat 710, an axis 3 712 is installed on the notch 4 711, the axis 3 712 is fixed to the other end of the connecting rod 2 720, an axis 4 713 is installed on the notch 4 711, a notch 5 714 is opened on the fixed seat 74, an axis 5 715 is installed on the notch 5 714, a connecting rod 3 716 is installed between the axis 4 713 and the axis 5 715, a support frame 717 is fixed on the gate body 1, a support rod 1 718 is installed on the support frame 717, a slide groove 4 719 is opened on the connecting rod 2 720, and the support rod 1 718 penetrates the slide groove 4 719.

[0057] The slide groove 3 71 and the slider 72 are cross-slidingly connected to limit the moving track of the slider 72. This is a prior art. When the slider 72 moves downward, due to the limitation of the slide groove 1 300, the blocking plate 301 can only move horizontally in the slide groove 1 300. When the slider 72 moves downward, the shaft 1 76 on the slider 72 squeezes the shaft 1 76 on the fixed seat 74 through the connecting rod 1 77, so that the fixed seat 74 drives the blocking plate 301 to move in the direction of the gate body 1, releasing the L groove 3 1, when the slider 72 moves upward, a force to restore the blocking plate 301 is applied to the blocking plate 301. At the same time, under the action of the support rod 1 718, the connecting rod 2 720 rotates during the movement, and the center of the circle moves proportionally in the slide groove 4 719. The rotation of the connecting rod 2 720 changes the position of the connecting seat 710 at its top. The shaft 4 713 on the connecting seat 710 squeezes the shaft 5 715 on the notch 5 714 through the connecting rod 3 716, thereby driving the blocking plate 301 away from the gate body 1.

[0058] The transmission mechanism 8 includes a pressure rod 81 installed through the slide 51, a limiting plate 82 is installed on the pressure rod 81, the limiting plate 82 is connected with the slide 51 with a gap, and clamps the slide 51, a metal spring 83 is installed on the pressure rod 81, the metal spring 83 is arranged in a mirror image, and there are two groups, the slider 72 is installed with a second support rod 84, and the second support rod 84 is installed with a square block 85, and the four corners of the square block 85 are all inclined surfaces;

[0059] A reset mechanism 9 is installed on the gate body 1. When the power is restored, the reset mechanism 9 restores the interception rod 2 to its original position, drives the blocking plate 301 to block the L groove 31, and restores the metal weight block 41 to its original position.

[0060] The limiting plate 82 restricts the pressure rod 81 from rotating. During the continuous falling of the metal weight block 41, the metal weight block 41 presses the pressure rod 81, causing the pressure rod 81 to fall along the second slide groove 58. During the falling of the pressure rod 81, the metal spring piece 83 on the pressure rod 81 clamps the square block 85, and then continues to drive the slider 72 downward through the square block 85 and the second support rod 84. At this time, since the falling speed of the intercepting rod 2 is slower than that of the metal weight block 41, the blocking plate 301 can release the blockage of the L groove 31 before the intercepting rod 2 contacts the blocking plate 301. When the pressure rod 81 rises, the metal spring piece 83 drives the square block 85 to rise synchronously. When the slider 72 is located at one end of the slide groove 3 71, the resistance encountered by the metal spring piece 83 increases, and it slides along the hypotenuse of the four corners of the square block 85 to release the contact with the square block 85. The metal spring piece 83 can also be replaced with an elastic object in the prior art, which can achieve the same effect.

[0061] The reset mechanism 9 includes an electric slide rail 91 installed on the gate body 1 , a lifting plate 92 is installed on the electric slide rail 91 , and the lifting plate 92 is L-shaped, and also includes a reset member 90 installed in the gate body 1 .

[0062] The reset member 90 includes a guide rail 901 which is relatively opened on the gate body 1, and the guide rail 901 has the same shape as the guide rail 511. A linkage block 902 is installed on the guide rail 901, and an L-plate 903 is installed on the top of the linkage block 902. A slide groove 904 is opened on the gate body 1, and the slide groove 904 passes through the base 3. A plate 905 is installed on the lifting plate 92, and the plate 905 passes through the slide groove 904, and the top part overlaps with the L-plate 903.

[0063] After the power is restored, the electric slide rail 91 is turned on, and the electric slide rail 91 drives the lifting plate 92 to rise, and the lifting plate 92 drives the intercepting rod 2 to continue to rise in the guide rail 1 511 until it returns to its original position. In this process, the second plate 905 on the lifting plate 92 slides synchronously in the slide groove 5 904. During the movement of the second plate 905, the L plate 903 is driven to rise synchronously. During the rise of the L plate 903, the pressure rod 81 and the metal weight block 41 are driven to rise synchronously. The rise of the pressure rod 81 drives the blocking plate 301 to re-block the L groove 31. At the same time, the L plate 903 drives the linkage block 902 to move in the guide rail 2 901. When it rises to a certain height, the L plate 903 moves between the guide rail 2 901 and the metal weight block 41. Under the action of the linkage block 902, it rotates along the guide rail 901. At this time, the plate 905 is separated from the L plate 903. At this time, the distance between the metal weight block 41 and the electromagnet 4 is relatively close, and the magnetic force of the electromagnet 4 is equal to the gravity of the metal weight block 41. Under the action of the electromagnet 4, the metal weight block 41 is temporarily suspended in the slide 51. When the intercepting rod 2 returns to its original position, the electromagnet 4 increases the magnetic force to drive the metal weight block 41 to completely reset. For this part of the operation, technicians in this field only need to perform simple programming on the gate body 1 to achieve it. It is a prior art. During this process, the metal weight block 41 blocks the air hole 59. With the continuous resetting, the motor 11 and the clamping plate 65 are reset synchronously.

[0064] The intercepting rod 2 is divided into two parts, namely a rotating part 200 and an intercepting part 201. The intercepting part 201 is fixed to the rotating part 200 through a telescopic shaft 202. The telescopic shaft 202 is hollow and has a built-in spring 203. One end of the telescopic shaft 202 is fixed to the intercepting part 201, and the other end is fixed with a hexagonal block 204. A hemispherical body 205 is installed on the hexagonal block 204. One end of the intercepting part 201 and the rotating part 200 are respectively provided with a hexagonal groove 206, and a part of the hemispherical body 205 overlaps with the support plate 510.

[0065] Under the action of the support plate 510 on one side of the gate body 1, when the intercepting rod 2 is completely parallel to the ground, the support plate 510 blocks the hemisphere 205, causing the telescopic shaft 202 to be in a compressed state. In this state, the hexagonal block 204 penetrates the intercepting part 201 and the rotating part 200 at the same time, so that the intercepting part 201 cannot rotate, preventing people from maliciously lifting the rod to leave the site. When the intercepting rod 2 is not parallel to the ground, the support plate 510 is lost. The telescopic shaft 202 is in an extended state under the action of the spring 203, and the hexagonal block 204 is separated from the intercepting part 201. At this time, the intercepting part 201 is in a foldable state, reducing the damage to vehicles and people when falling.

[0066] The working principle of the present invention is as follows: when the gate body 1 is suddenly powered off, the magnetic force of the electromagnet 4 is lost, and the metal weight block 41 slides down in the slide cylinder 51 under the action of gravity, and negative pressure is generated between the top of the metal weight block 41 and the upper part of the slide cylinder 51. This pressure is transmitted through the pipeline 54, causing a huge negative pressure to be generated in the piston cylinder 56. Under the action of the negative pressure, the piston rod 57 drives the motor 11 fixedly connected thereto to move synchronously. At this time, the top of the motor 11 is separated from the intercepting rod 2, and the support of the output shaft of the motor 11 is lost. Under the action of the intercepting rod 2's own gravity, the intercepting rod 2 falls along the guide rail 511. Due to the special shape of the guide rail 511, even if the intercepting rod 2 is fully raised or half raised, it can fall, and the motor 11 is After being completely separated from the intercepting rod 2, the top of the metal weight block 41 just releases the blockage of the air hole 59. At this time, the metal weight block 41 continues to fall. When the motor 11 moves, the motor 11 drives the rod 2 62 fixed with the ring 63 to move synchronously through the fixing frame 64. The rod 2 62 drives the clamping plate 65 to approach the intercepting rod 2. The resistance increasing plate 66 on the clamping plate 65 fits with one side of the intercepting rod 2, thereby increasing the resistance of the intercepting rod 2 during the rotation and falling process, slowing down its speed during the rotation and falling process, and giving the personnel inside the vehicle enough reaction time to respond. During the continuous falling of the metal weight block 41, the metal weight block 41 presses the pressure rod 81, causing the pressure rod 81 to fall along the chute 2 58. The falling process of the pressure rod 81 During the process, the metal spring piece 83 on the pressure rod 81 clamps the square block 85, and then continues to drive the slider 72 to move downward through the square block 85 and the support rod 2 84. At this time, since the interception rod 2 falls slower than the metal weight block 41, the blocking plate 301 can release the blockage of the L groove 31 before the interception rod 2 contacts the blocking plate 301. When the pressure rod 81 rises, the metal spring piece 83 drives the square block 85 to rise synchronously. When the slider 72 is located at one end of the slide groove 3 71, the resistance of the metal spring piece 83 increases, and it slides along the hypotenuse of the four corners of the square block 85 to release the contact with the square block 85. The metal spring piece 83 can also be replaced with an elastic object in the prior art, which can achieve the same effect. After the power is restored, the electric slide rail 91 is turned on and the power is turned on. The movable slide rail 91 drives the lifting plate 92 to rise, and the lifting plate 92 drives the intercepting rod 2 to continue to rise in the guide rail 1 511 until it returns to its original position. In this process, the second plate 905 on the lifting plate 92 slides synchronously in the slide groove 5 904. During the movement of the second plate 905, the L plate 903 is driven to rise synchronously. During the rising process of the L plate 903, the pressure rod 81 and the metal weight block 41 are driven to rise synchronously. The rising pressure rod 81 drives the blocking plate 301 to re-block the L groove 31. At the same time, the L plate 903 drives the linkage block 902 to move in the guide rail 2 901. When it rises to a certain height, the L plate 903 rotates along the guide rail 2 901 under the action of the guide rail 2 901 and the linkage block 902. At this time, the second plate 905 is separated from the L plate 903.At this time, the distance between the metal weight block 41 and the electromagnet 4 is relatively close, and the magnetic force of the electromagnet 4 is equal to the gravity of the metal weight block 41. Under the action of the electromagnet 4, the metal weight block 41 is temporarily suspended in the slide 51. When the interception rod 2 returns to its original position, the electromagnet 4 increases the magnetic force to drive the metal weight block 41 to completely reset. During this process, the metal weight block 41 blocks the air hole 59. As the reset continues, the motor 11 and the clamping plate 65 are reset synchronously.

[0069] Rollers 207 are installed on both the upper and lower surfaces of the slide 300. There are a plurality of rollers 207, which clamp the blocking plate 301.

[0070] The friction force of the blocking plate 301 during movement is greatly reduced, and the overall device is more stable during operation.

[0071] A soft elastic sheet is provided at the bottom end of the intercepting portion 201 of the intercepting rod 2.

[0072] Further reduce the damage that the vehicle may suffer during the fall.
