By improving the movement assembly, a centrally installed motor installation position is set in the middle of the upper end of the chassis on the structure of the chassis. When the motor is installed, the motor is centrally installed on the chassis by relying on the motor clamping plate assemblies on both sides, and can be installed by bolts, which is more convenient for later maintenance. As for the spring buffer assembly in the movement assembly, two buffer assemblies are provided, the first buffer assembly is linked with the power connecting rod assembly, and the second buffer assembly is linked with the main rotating shaft on the other side. The two groups of buffer assemblies are respectively located on both sides of the motor output shaft, which can evenly convert the force from the upper handle and the barrier rod to the up and down swinging into the tension of the spring buffer, so that the barrier rod is more stable when it swings up and down. At the same time, the layout of the centrally installed motor and the double buffer assembly can also make the torque of the barrier structure larger. When the same motor power is used, a longer and heavier barrier rod can be installed.

Description

Technical Field

[0001] The utility model relates to the technical field of barrier gate chassis, in particular to a barrier gate with large torque and double-sided buffering that can be centrally installed. Background Art

[0002] In the existing barrier gate chassis structure, the rod handle (the component connected to the barrier gate rod) is mostly installed on the side of the chassis, and the output torque of the main shaft drives the rod handle to rotate, while a tension spring is added to the other side of the main shaft as a buffer. In this structure, the distance between the gate rod and the power arm of the main shaft is too far, which increases the working load of the motor and cannot achieve high torque. Therefore, the length and weight of the barrier gate rod at its end cannot be increased. For some wider passage openings, a single barrier gate rod cannot complete the control. In addition, in traditional barrier gate movement components, most motors are installed on both sides instead of in the middle, so that the layout inside the chassis can be better, but the problems caused by this layout are as mentioned above. The space on the side of the chassis is limited, and a large-torque and large-volume motor cannot be installed. In the traditional fixing method of the motor and the chassis, welding is adopted to make it more firm. When there is a problem with the motor later, it is very troublesome to repair or disassemble it, and it is not easy to replace or maintain. The above problems need to be solved urgently.

[0027] Specifically, the chassis 10 includes a side cover 110 and an upper cover 120, wherein the upper cover 120 is provided with a first avoidance groove 111, a second avoidance groove 112 and a third avoidance groove 113, wherein the first avoidance groove 111 and the second avoidance groove 112 are both hollow grooves for allowing the power connecting rod assembly 200 or the first buffer assembly 1 or the second buffer assembly 2 to pass through, and the third avoidance groove 113 is used to make way for the handle 30 when it is rotated to a horizontal angle, and the width and depth of the third avoidance groove 113 can be adjusted according to the width and depth of the handle 30.

[0028] Specifically, the upper inner sides of the chassis 10 are symmetrically provided with fixing seats 130, and a motor mounting position 101 is formed between the fixing seats 130 on both sides, and also includes a motor clamping plate assembly 400, and the motor clamping plate assembly 400 includes a front clamping plate 410 and a rear clamping plate 420, and the front clamping plate 410 and the rear clamping plate 420 both have a clamping portion 411 and a fixing portion 412, wherein the clamping portion 411 is used to accommodate the motor 100 body and the output shaft of the power supply machine 100 to pass through, and the fixing portion 412 is used to be fixed with the fixing seats on both sides. 130 is installed and fixed. With this arrangement, the motor 100 can be centrally installed on the inner side of the upper end of the chassis 10 to facilitate uniform torque distribution. At the same time, the motor 100 is clamped and installed by the clamps on both sides. The fixing plate 13 of the motor 100 is fixed on the inner side of the front clamp 410 and the rear clamp 420, and the front clamp 410 and the rear clamp 420 are fixed on the fixing seats 130 on both sides, so as to be fixedly connected with the chassis 10. When the motor 100 needs to be repaired, it is only necessary to disassemble the front clamp 410 and the rear clamp 420, which is very convenient.

The first limit mechanism 510 limits the maximum stroke, and the second limit mechanism 520 can control the specific angular stroke of the large swing arm 201 through the travel switches 521 distributed in a plurality of circular arrays at the upper end. For example, if 6 travel switches 521 are distributed in 360 degrees, each travel switch 521 is responsible for the 160-degree rotation angle of the large swing arm 201. The rotation angle of the end barrier rod is controlled here. Usually a normal value is set, such as rotating 90 degrees, and the barrier rod is lifted from the horizontal to the vertical state by default. Of course, this setting can be determined according to actual conditions.

The third limit mechanism 530 includes a rotating rod 531 and a limit rod 532. The rotating rod 531 is sleeved on one side of the main rotating shaft 300 and linked thereto. The rotating rod 531 has at least two forked structures, and the limit rod 532 has two, which are separated on both sides of the main rotating shaft 300 and on the upper cover 120 of the chassis 10. The third limit mechanism 530 is directly arranged on the main rotating shaft 300. This mechanism is directly related to the rotation of the barrier rod at the upper end. The rotation angle of the barrier rod can be controlled by adjusting the angular position of the rotating rod 531 on the main rotating shaft 300. It is preferred that the three limit mechanisms are manually adjusted to a linkage through system control or measurement, so that they are not easy to fail, and each rod lifting and lowering can be accurate.

[0031] The utility model improves the movement assembly 20, wherein the structure of the chassis 10 is provided with a centrally installed motor mounting position 101 in the middle of the upper end of the chassis 10. When the motor 100 is installed, the motor 100 is centrally installed on the chassis 10 by relying on the motor clamping plate assemblies 400 on both sides, and can be installed by bolts, so that it is more convenient for later maintenance. In addition, for the spring buffer assembly in the movement assembly 20, compared with the traditional single-sided pull spring buffering form, here, a first buffer assembly 1 and a second buffer assembly 2 are provided, the first buffer assembly 1 is linked with the power connecting rod assembly 200, and the second buffer assembly 2 is on the other side. Through the linkage of the main shaft 300, and the two groups of buffer components are respectively located on both sides of the output shaft of the motor 100, the force from the upper rod handle 30 and the barrier pole swinging up and down can be evenly converted into the tension of the spring buffer, so that the barrier pole is more stable when swinging up and down. At the same time, the centrally installed motor 100 and the layout of the double buffer components can also make the torque of this barrier structure larger. When the power of the same motor 100 is used, a longer and heavier barrier pole can be installed. In other words, the reasonable structural layout of the present structure can make the structure of the chassis 10 larger and able to withstand a longer and larger barrier pole so as to be installed at a wider entrance and exit.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
