Description

Technical Field

[0001] The utility model relates to the technical field of entrance and exit management equipment, in particular to a barrier gate movement and a barrier gate. Background Art

[0002] Barrier gates, also known as vehicle blockers, are specially used for managing the entrance and exit of passages on roads to restrict the travel of motor vehicles. They are now widely used in highway toll stations and parking lot systems to manage vehicle passages and to manage the entry and exit of vehicles. With the rapid increase in the number of cars, the demand for barrier gates is also increasing, and higher requirements are also placed on the performance of barrier gates. Barrier gates have been increasingly developing towards high-tech aspects to meet the market demand for products.

[0003] The barrier gate is mainly composed of a barrier gate mechanism and a gate rod. A driving device, a transmission device and a tension spring are arranged in the barrier gate mechanism. The transmission device is connected to the driving device and the tension spring respectively, and is used to transmit the driving force of the driving device to the gate rod to control the raising and lowering of the gate rod. During the raising and lowering process of the gate rod, the tension spring is tightened and relaxed to achieve stable raising and lowering of the gate rod.

[0004] In actual use, due to the influence of the installation environment and the length of the gate rod, the staff needs to go to the site to adjust the installation position of the tension spring so that the tension spring meets the corresponding torque requirements. However, this process is time-consuming and labor-intensive, and the operation is very inconvenient. Utility Model Content

[0041] Figure 1 It is a structural schematic diagram of a barrier gate mechanism provided in an embodiment of the utility model.

[0042] See also Figure 1 An embodiment of the utility model provides a barrier gate movement, which includes a chassis 100, a driving device 200 and an adjusting device 300.

[0043] The chassis 100 is a rectangular box structure, including a shell and a cover (not shown in the figure). A accommodating cavity is constructed in the shell. The cover is detachably connected to one side of the shell for closing the accommodating cavity. The driving device 200 and the adjusting device 300 are both arranged in the accommodating cavity, and the gate rod 400 of the gate is rotatably connected to the chassis 100.

[0044] The driving device 200 is arranged in the accommodating cavity of the chassis 100, and the driving device 200 includes a driving assembly 210, a connecting rod mechanism 220 and a tension spring 230. The connecting rod mechanism 220 is connected to the output end of the driving assembly 210, and the connecting rod mechanism 220 is connected to the first end of the tension spring 230. It is equivalent to that the output end of the driving assembly 210 is connected to the connecting rod mechanism 220 and the gate rod 400 respectively, and under the premise of driving the gate rod 400 to rotate to realize the lifting or falling of the gate rod 400, the connecting rod assembly is driven to move at the same time, so that the tension spring 230 is tightened or relaxed to realize the stable lifting and lowering of the gate rod 400.

[0045] The adjusting device 300 is disposed in the accommodating cavity of the chassis 100. The adjusting device 300 is connected to the second end of the tension spring 230 and is adapted to adjust the installation position of the tension spring 230 according to the elastic force of the tension spring 230 to change the tension of the tension spring 230. Thus, the tension spring 230 can adapt to different installation environments and the length of the gate rod 400. For example, when the length of the gate rod 400 is long and the tension of the tension spring 230 required is increased, the installation position of the tension spring 230 is adjusted by the adjusting device 300 so that the distance between the second end and the first end of the tension spring 230 is increased, thereby reducing the shaking phenomenon when the gate rod 400 is raised or lowered. When the length of the gate rod 400 is short, the tension of the tension spring 230 required is reduced, and the installation position of the tension spring 230 is adjusted by the adjusting device 300 so that the distance between the second end and the first end of the tension spring 230 is reduced, thereby reducing the shaking phenomenon when the gate rod 400 is raised or lowered.

[0046] It is understandable that the gate mechanism provided by the embodiment of the utility model is suitable for adjusting the installation position of the tension spring 230 according to the elastic force of the tension spring 230 by setting the adjustment device 300 in the chassis 100 so that the adjustment device 300 is connected to the second end of the tension spring 230, so as to change the tension of the tension spring 230, so that the tension spring 230 can adapt to different installation environments and the length of the gate rod 400. For example, when the length of the gate rod 400 is long and the required tension of the tension spring 230 is increased, the installation position of the tension spring 230 is adjusted by the adjustment device 300 so that the distance between the second end and the first end of the tension spring 230 is increased, thereby reducing the shaking phenomenon when the gate rod 400 is raised and lowered. When the length of the gate rod 400 is short, the required tension of the tension spring 230 is reduced, and the installation position of the tension spring 230 is adjusted by the adjustment device 300 so that the distance between the second end and the first end of the tension spring 230 is reduced, thereby reducing the shaking phenomenon when the gate rod 400 is raised and lowered.

[0047] In addition, after the barrier has been used for a period of time, the tension spring 230 is tightened or relaxed multiple times, which weakens the elastic restoring force. When tension adjustment is required, the installation position of the tension spring 230 can be adjusted by the adjustment device 300 to achieve the purpose of tensioning the tension spring 230.

[0048] Continue reading Figure 1 In some embodiments of the utility model, the adjustment device 300 includes a limit assembly 310 and an adjustment assembly 320. The limit assembly 310 is provided with a plurality of limit portions 330 at intervals along the extension direction of the tension spring 230. The adjustment assembly 320 is fixedly connected to the second end of the tension spring 230, and is suitable for driving the tension spring 230 to adjust to the corresponding limit portion 330, so as to achieve the purpose of adjusting the installation position of the tension spring 230.

[0049] It can be understood that a limit assembly 310 is provided on the inner wall of the chassis 100, and the limit assembly 310 is provided along the extension direction of the tension spring 230, that is, along the stretching direction of the tension spring 230, to ensure that the adjustment assembly 320 is always located on the deformation path of the tension spring 230, and can adapt to the adjustment of different positions of the tension spring 230. A plurality of limit parts 330 are provided on the limit assembly 310, and the adjustment assembly 320 cooperates with the limit parts 330 to achieve limit, so as to fix the position of the tension spring 230. Therefore, the structural shape of the limit part 330 can be adaptively changed according to the structural shape of the adjustment assembly 320.

[0050] Continue reading Figure 1 In some embodiments of the present invention, the adjustment component 320 includes an adjustment component 321, a first driving component 322 and a second driving component 323. The adjustment component 321 is arranged at the output end of the first driving component 322, and the first driving component 322 can be fixedly arranged on the second driving component 323.

[0051] Among them, the adjustment component 321 can be a rod-shaped member, a plate-shaped member or a protrusion. The adjustment component 321 is fixedly connected to the second end of the tension spring 230 by fasteners such as bolts and screws, and can drive the tension spring 230 to move synchronously to change the installation position or connection position.

[0052] The first driving component 322 is used to drive the adjusting component 321 to move along the first direction, so that the adjusting component 321 switches between the limit position and the limit release position. For example, the first driving component 322 can be a linear motor, that is, a motor that can generate linear motion. The linear motor converts electrical energy into mechanical energy of linear motion without the need for an intermediate transmission mechanism for conversion. The load (that is, the adjusting component 321) can be directly connected to drive the adjusting component 321 to perform linear reciprocating motion, close to the limit portion 330 to cooperate with the limit portion 330 to achieve limit, or away from the limit portion 330 to be in a contact limit position.

[0053] The second driving component 323 is used to drive the first driving component 322 and the adjusting component 321 to move in a second direction perpendicular to the first direction to change the position of the adjusting component 321, thereby adjusting the tension spring 230 at different positions. For example, when the first driving component 322 drives the adjusting component 321 to move in the first direction to the limit release position, the second driving component 323 drives the first driving component 322 and the adjusting component 321 to move in the second direction to adjust the position of the adjusting component 321 along the stretching direction of the tension spring 230, so that the adjusting component 321 drives the tension spring 230 to be tensioned or contracted.

[0054] The second drive component 323 can be the same as the first drive component 322, both of which are linear motors, that is, motors that can generate linear motion. The linear motor converts electrical energy into mechanical energy of linear motion without the need for an intermediate transmission mechanism for conversion, and can be directly connected to the load. Of course, the first drive component 322 and the second drive component 323 can also be driven by a motor and a transmission mechanism, for example, the first drive component 322 and the second drive component 323 are both screw nut pairs.

[0055] Continue reading Figure 1 In some embodiments of the present invention, the limiting assembly 310 includes a mounting member 311 and a limiting member 312. The mounting member 311 is arranged on the inner wall of the chassis 100, and the height direction of the mounting member 311 is arranged along the extension direction of the tension spring 230. The limiting members 312 are arranged at intervals along the height direction of the mounting member 311 (that is, along the extension direction of the tension spring 230) to form a limiting portion 330 between two adjacent limiting members 312.

[0056] In other words, the limiting component 310 is composed of two independently arranged parts, namely, a plate-shaped or columnar mounting member 311 and a rod-shaped limiting member 312. The limiting member 312 can be fixed on the mounting member 311 by fasteners such as screws and bolts, and a gap is provided between two adjacent limiting members 312 to form a limiting portion 330.

[0057] Of course, the limiting component 310 may also include an integrally formed mounting member 311 and a limiting member 312 , which is equivalent to providing grooves at intervals on the mounting member 311 to form a limiting portion 330 , and forming a limiting protrusion between two adjacent grooves, which forms the limiting member 312 .

[0058] Figure 2 It is a structural schematic diagram of another embodiment of a barrier gate movement provided by an embodiment of the utility model.

[0059] See also Figure 2 In some embodiments of the present invention, the limiting area of ​​the limiting member 312 gradually increases from the position of the tension spring 230 to the direction away from the tension spring 230 .

[0060] As the direction away from the tension spring 230 increases, the tensioning force of the tension spring 230 becomes greater and greater, and thus the required supporting force becomes greater. The limiting area of ​​the limiting member 312 is adaptively adjusted so that the limiting area of ​​the limiting member 312 gradually increases, that is, the length of the limiting member 312 can be increased, or the width of the limiting member 312 can be increased, thereby increasing the limiting strength of the limiting member 312 to adapt to the limiting force required by the tension spring 230.

[0061] In some embodiments of the present invention, in addition to gradually increasing the limiting area of ​​the limiting member 312 from the position of the tension spring 230 to the direction away from the tension spring 230 , the supporting area of ​​the mounting member 311 can also be gradually increased.

[0062] Similarly, since the tensioning force of the tension spring 230 becomes greater and greater in the direction away from the tension spring 230, the required supporting force is greater. The supporting area of ​​the mounting member 311 is adaptively adjusted to gradually increase the supporting area of ​​the limiting member 312. That is, the thickness or width of the mounting member 311 can be increased, thereby increasing the supporting strength of the mounting member 311 to adapt to the limiting force required by the tension spring 230.

[0063] In some embodiments of the utility model, the driving device 200 includes a motor and a speed reduction mechanism (not shown in the figure) connected to the motor, and the connecting rod mechanism 220 is connected to the output end of the speed reduction mechanism. By setting the speed reduction mechanism, the rotational inertia of the motor can be effectively reduced, and the start and stop and speed change can be controlled in time, so that the gate rod 400 can be raised and lowered more stably.

[0064] In some embodiments of the utility model, a limit block (not shown in the figure) is provided on the chassis 100, and the limit block is located on the running path of the connecting rod mechanism 220, and is used to limit the position of the connecting rod mechanism 220. It is prevented that the connecting rod mechanism 220 runs over the stroke, so as to prevent the connecting rod mechanism 220 and the tension spring 230 from causing the gate rod 400 to vibrate or shake when the gate rod 400 moves in a balanced manner.

[0065] In addition, some embodiments of the present invention further include a controller and a vibration sensor for monitoring the vibration amplitude of the gate rod 400, and the vibration sensor, the drivers of the first driving component 322 and the second driving component 323 are all connected to the controller.

[0066] A vibration sensor can be set on the gate rod 400 to monitor the vibration information of the gate rod 400 and feed the vibration information back to the controller. The controller can receive the vibration information of the vibration actuator and issue control instructions to the first drive component 322 and the second drive component 323 according to the vibration information to control the movement of the first drive component 322 and the second drive component 323 to adjust the position of the adjustment component 321, and then adjust the installation position of the tension spring 230.

[0067] When the gate mechanism is powered on, the driving device 200 drives the gate rod 400 to move so that the gate rod 400 is lifted or lowered, and the upper limit position and the lower limit position of the gate rod 400 are monitored by the position sensor to determine whether the gate rod 400 can move to the upper limit position or the lower limit position.

[0068] If the gate rod 400 can move to the upper limit position or the lower limit position, the vibration amplitude and vibration frequency of the gate rod 400 are monitored by the vibration sensor. If the vibration amplitude of the gate rod 400 is too large, it indicates that the gate rod 400 is shaking and has poor stability. It is necessary to control the movement of the first driving component 322 and the second driving component 323 to adjust the position of the adjustment component 321, and then adjust the installation position of the tension spring 230 to adapt and match the tension of the tension spring 230 to reduce the shaking of the gate rod 400. After adjusting the tension of the tension spring 230, the controller saves the adjusted data for next use.

[0069] If the gate rod 400 cannot move to the upper limit position or the lower limit position, it means that the current of the driving device 200 does not match, and the current of the driving device 200 needs to be adaptively adjusted so that the gate rod 400 can operate reasonably.

[0070] Among them, when the vibration frequency and amplitude of the gate rod 400 are obtained by the vibration sensor and the first driving component 322 and the second driving component 323 are controlled to adjust the position of the adjustment component 321, the movement steps of the first driving component 322 and the second driving component 323 can be controlled to determine. The movement steps can be obtained by investigation in the research and development stage, and the relevant data can be quickly found in actual use for control, for example, refer to the following Table 1:

[0071] Table 1 shows the relationship between the shaking frequency and amplitude of the gate rod and the movement steps of the first driving component and the second driving component.

[0072]

[0073] As can be seen from Table 1, the first driving component 322 and the second driving component 323 drive the tension spring 230 to adjust its position so that the tensioning force of the tension spring 230 is adjusted to a suitable value, thereby ensuring the stability of the gate rod 400 when it rises and falls and avoiding abnormal shaking of the gate rod 400. Here, the position (0,0) is an ideal position.

[0074] The embodiment of the utility model also provides a barrier gate, which includes a gate rod 400 and the above-mentioned barrier gate mechanism; the gate rod 400 is movably connected to the barrier gate mechanism to switch between an open state for opening a driving channel and a closed state for closing the driving channel.

[0075] The gate rod 400 is a rod body with an octagonal cross section, one end of which is rotatably connected to the gate mechanism and the other end is suspended in the air.

[0076] It should be noted that the technical solutions in various embodiments of the present utility model can be combined with each other, but the basis for the mutual combination is that it can be implemented by ordinary technicians in the field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist, that is, it does not belong to the protection scope of the present utility model.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
