technical field

The utility model relates to the technical field of barrier gate equipment, in particular to an anti-pinch type barrier gate.

Background technique

The "National Smart City" plan has accelerated the construction of a series of public support application platforms such as cloud computing, Internet of Things, and big data. The construction of smart cities will move towards planning and Internetization. Among them, the construction of smart communities occupies an important position. In the prior art, with the continuous development of the automobile industry and the rapid increase in the number of automobiles, the barrier gate has become an indispensable part of the intelligent community management system.

Barrier gates are traffic management equipment at the entrances and exits of driving passages, and further optimizing the performance of the barrier gates is a technical problem to be solved urgently by those skilled in the art.

Utility model content

In view of the further optimization of the performance of the barrier gate proposed above, it is a technical problem to be solved urgently by those skilled in the art. The utility model provides an anti-pinch type barrier gate. The use of this barrier gate requires a small space height for the installation position , At the same time, it is not easy to jam during the action.

An anti-pinch type barrier gate provided by the utility model solves the problem through the following technical points. An anti-pinch type barrier gate includes a power box, and the power box is provided with a power device, and also includes a vertical rod, a connecting arm and crossbar;

The vertical rod is arranged vertically, and the lower end of the vertical rod is connected with a power device, and the power device is used to drive the vertical rod to perform lifting movement in the vertical direction;

The connecting arm is arranged horizontally, and one end of the connecting arm is fixedly connected with the vertical pole;

One end of the crossbar is connected to the connecting arm, and the free end of the crossbar extends to the outside of the free end of the connecting arm;

It also includes a reinforcement rod whose upper end is fixedly connected to the free end of the connecting arm, the reinforcement rod is parallel to the vertical rod, and a strip-shaped guide hole is provided on the power box, the reinforcement rod is embedded in the guide hole, and the reinforcement rod is inserted into the guide hole. When the rod moves up and down with the vertical rod, the reinforcing rod slides along the length direction of the guide hole.

When this scheme is in use, the area that the crossbar can cover is used as the road limit width of this barrier. When the height of the crossbar relative to the road surface is low, the crossbar is in the state of road interception. When the barrier needs to release the vehicle to pass through, the power device drives the vertical pole to move upward, so that the crossbar rises to the crossbar with the vertical pole. It is enough that the lower part of the car has a height that can pass through the vehicle. After the vehicle passes, the vertical bar is lowered under the action of the power device, and the cross bar is lowered with the vertical bar to the state of vehicle passing connection. Since the existing community parking lot is used for the passage of motor vehicles, the roads are several meters wide, so the length of the crossbar also needs to be set to several meters in order to realize the comprehensive interception of the road by the crossbar. In this solution, the horizontal bar releases the vehicle to pass because it rises with the vertical bar. Therefore, compared with the barrier gate that needs to be turned over by the horizontal bar, this solution requires less space and height for the installation position.

In this solution, the reinforcing rod is used to reduce the bending deformation on the vertical bar: the above horizontal bar is the cantilever on the barrier, and the gravity of the horizontal bar applies a bending moment towards the side of the center of gravity of the vertical bar for the vertical bar, and the above bending The moment forces the bending deformation of the vertical rod. Since the lower end of the reinforcing rod is embedded in the guide hole on the power box, the bending of the vertical rod causes a positive pressure between the side of the reinforcing rod and the wall of the guiding hole. At this time, the reinforcing rod is sheared. The bending is used to balance part of the bending moment, so as to reduce the bending deformation of the pole. The smaller bending deformation of the above vertical rod is beneficial to the matching accuracy of the vertical rod and the power device and/or the matching precision of the vertical rod and the power box, so as to achieve the purpose of reducing the jamming phenomenon. At the same time, the scheme is simple in structure and easy to manufacture.

A further technical solution is:

It also includes a hinge shaft, through which the crossbar is hingedly connected to the connecting arm, the installation point of the hinge shaft on the connecting arm is located between the two ends of the connecting arm, and the other end of the connecting arm can provide support for the bottom of the crossbar;

The horizontal bar can be overturned on the side where the vertical bar is located with the hinge axis as the rotating shaft.

When this program is in normal use, the center of the crossbar falls on the outside of the other end of the connecting arm. In this way, the hinge point of the crossbar and the connecting arm, the bottom of the crossbar and the support point of the connecting arm work together to make the crossbar relatively The free end of the connecting arm protrudes relative to the connecting arm in the form of a cantilever rod in a specific extending direction.

The above cross bar is hingedly connected to the connecting arm through the end, and the bottom is supported by the connecting arm. When the cross bar is hindered by the roof, pedestrians, etc. during the falling process, the above cross bar can be rotated on the hinge axis as the rotating shaft. In this way, It can greatly reduce the damage to the roof, pedestrians, etc. caused by the collision between the crossbar and the roof, pedestrians, etc.

As a specific implementation form of the connecting arm, the connecting arm is a channel steel, and after the connecting arm is connected to the vertical rod, the opening direction of the notch of the channel steel faces upward;

The end of the cross bar connected with the connecting arm is embedded in the notch of the channel steel;

The length direction of the hinge shaft is parallel to the width direction of the slot on the channel steel, and the two ends of the hinge shaft are respectively supported by different side plates on the channel steel. In this solution, the connecting arm can be obtained by selecting existing conventional profiles. In the prior art, the channel steel includes three sides: the side plates on both sides and the web in the middle. The two ends of the above hinge shaft are supported by different side plates, which not only makes the connection between the hinge shaft and the connecting arm reliable, but also It can avoid that the axis of the hinge shaft changes greatly after a certain wear and tear of the hinge shaft or the corresponding shaft hole occurs. The groove bottom of the above notch, that is, the less surface of the web, is used as a supporting surface for supporting the cross bar.

As a specific implementation form of the power device and its connection with the vertical rod, the power device includes a drive motor, a reducer and a toothed plate, and the toothed plate is connected to the drive motor through the reducer;

The toothed plate is in the shape of a gear, and the lower end of the vertical rod is provided with a plurality of racks meshing with the teeth of the toothed plate. The toothed plate drives the vertical rod to move up and down through forward and reverse rotation. In this solution, through the rotation of the toothed plate at a specific position, according to the direction of rotation, the teeth on the toothed plate can exert force on the rack on the vertical rod, thereby forcing the vertical rod to rise or fall.

In order to facilitate drivers to identify the barrier and to prevent vehicles from directly colliding with the crossbar, marking strips are provided on the front and rear sides of the crossbar, and color coatings and reflective coatings are provided on the marking strips. In this solution, the rising color coating is mainly used for the driver to identify the crossbar during the day, and the above reflective coating is mainly used for the driver to identify the crossbar at night.

In order to enable the automatic stop of the power plant when the cross bar is constrained by the obstacles below, the bottom of the cross bar is also provided with a pressure sensor, and the output end of the pressure sensor is connected to the control circuit of the power plant .

As a form of pressure sensor with low installation cost and large coverage area, the pressure sensor is a strip-shaped force-sensitive resistor, and the force-sensitive resistor is laid along the length direction of the cross bar.

The utility model has the following beneficial effects:

When this scheme is in use, the area that the crossbar can cover is used as the road limit width of this barrier. When the height of the crossbar relative to the road surface is low, the crossbar is in the state of road interception. When the barrier needs to release the vehicle to pass through, the power device drives the vertical pole to move upward, so that the crossbar rises to the crossbar with the vertical pole. It is enough that the lower part of the car has a height that can pass through the vehicle. After the vehicle passes, the vertical bar is lowered under the action of the power device, and the cross bar is lowered with the vertical bar to the state of vehicle passing connection. Since the existing community parking lot is used for the passage of motor vehicles, the roads are several meters wide, so the length of the crossbar also needs to be set to several meters in order to realize the comprehensive interception of the road by the crossbar. In this solution, the horizontal bar releases the vehicle to pass because it rises with the vertical bar. Therefore, compared with the barrier gate that needs to be turned over by the horizontal bar, this solution requires less space and height for the installation position.

In this solution, the reinforcing rod is used to reduce the bending deformation on the vertical bar: the above horizontal bar is the cantilever on the barrier, and the gravity of the horizontal bar applies a bending moment towards the side of the center of gravity of the vertical bar for the vertical bar, and the above bending The moment forces the bending deformation of the vertical rod. Since the lower end of the reinforcing rod is embedded in the guide hole on the power box, the bending of the vertical rod causes a positive pressure between the side of the reinforcing rod and the wall of the guiding hole. At this time, the reinforcing rod is sheared. The bending is used to balance part of the bending moment, so as to reduce the bending deformation of the pole. The smaller bending deformation of the above vertical rod is beneficial to the matching accuracy of the vertical rod and the power device and/or the matching precision of the vertical rod and the power box, so as to achieve the purpose of reducing the jamming phenomenon. At the same time, the scheme is simple in structure and easy to manufacture.
