Description
Technical Field
[0001] The utility model relates to the technical field of vehicle capture and barrier gates, in particular to a vehicle capture and barrier gate device at the entrance and exit of a construction site. Background Technique
[0002] The barrier gate, also known as a car stopper, is a special device for managing the access of motor vehicles on roads. It is now widely used in highway toll stations and parking lot systems to manage vehicle access. The barrier gate can be lifted and lowered separately by wireless remote control, or it can be in an automatic management state through a parking lot management system (i.e., an IC card management system). When a vehicle enters, it takes a card and the barrier gate lifts the crossbar. When a vehicle passes through the barrier gate, the anti-collision radar detects the passing of the vehicle. After the vehicle passes, when the anti-collision radar no longer detects the vehicle, it controls the crossbar to fall. Due to the particularity of construction sites, there are various special vehicles entering the construction site. These vehicles are often large in size and slow in speed, and the barrier gate needs to be installed with a long crossbar. The traditional vehicle capture and barrier gate at the entrance and exit of a construction site controls the deflection angle of the crossbar by controlling the operation and stop of the motor. When a special vehicle passes, the vehicle speed is slow, the crossbar is long, and the self-weight is large. When the motor lifts the crossbar, the motor burden is large. When the crossbar remains in a vertical state for a long time, it is easy for the motor to malfunction, resulting in safety hazards such as self-locking failure and crossbar dropping. Therefore, we propose a vehicle capture and barrier gate device at the entrance and exit of a construction site. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a vehicle capture and barrier gate device at the entrance and exit of a construction site, which is provided with an auxiliary self-locking device.

[0009] Furthermore, the automatic pole-lifting mechanism further includes an electric push rod. The electric push rod is arranged at the upper end of the front side wall of the housing.

[0010] Furthermore, the automatic pole-lifting mechanism further includes a driving component. The driving component includes a motor, a reduction box, and a coupling.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The vehicle capture barrier gate device at the entrance and exit of this construction site has the following advantages:
[0014] 1. The single-chip microcomputer controls the operation of the capture camera. The capture camera identifies vehicle information and then sends an electrical signal to the single-chip microcomputer. The single-chip microcomputer controls the operation of the motor. The output shaft of the motor drives the reduction gearbox to work, and the reduction gearbox drives the connecting shaft to rotate. The connecting shaft drives the crossbar to deflect upward until the crossbar is perpendicular to the ground. Then the vehicle starts to pass through the barrier gate. At the same time, the single-chip microcomputer controls the anti-collision radar to work. The anti-collision radar emits electromagnetic waves to detect the vehicle and then sends an electrical signal to the single-chip microcomputer. The single-chip microcomputer controls the electric push rod to work. The telescopic end of the electric push rod extends backward, pushing the extrusion ring to move backward. The second spring is compressed under force. As the extrusion ring moves, the inner wall of the extrusion ring slowly presses against the outer surface of the top cap, causing the sliding column to slowly contract inward. The first spring is compressed under force, and the locking head also moves inward accordingly until the locking head contacts the locking teeth to form a limit. At this time, the connecting shaft is locked. The cross-shaped distributed locking heads make the crossbar more stable. The crossbar can remain vertical for a long time without affecting the equipment. There is an auxiliary self-locking device. When a vehicle passes through the entrance and exit of the construction site, the crossbar can be automatically locked to maintain the stability of the crossbar and prevent the crossbar at the entrance and exit of the construction site from falling and damaging the vehicle and equipment.
[0015] 2. After all vehicles have passed through the barrier gate, when the anti-collision radar fails to detect the vehicle and obstacles, it sends an electrical signal to the single-chip microcomputer. The single-chip microcomputer controls the electric push rod to work. The telescopic end of the electric push rod returns to its original position. The front end of the extrusion ring is not stressed, and the second spring rebounds without stress, driving the extrusion ring back to its original position. As the extrusion ring moves, the top cap loses its restriction, and the first spring drives the sliding column and the locking head back to their original positions without stress. The locking head leaves the locking teeth. At this time, the connecting shaft loses its restriction. The single-chip microcomputer controls the motor to operate. The motor drives the reduction gearbox to work, and the reduction gearbox drives the connecting shaft to rotate. The crossbar returns to its original position to complete the lowering of the rod. After the vehicle at the entrance and exit of the construction site passes, the limit of the crossbar is automatically released. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The working principle of a vehicle capture barrier device at the construction site entrance and exit provided by the present utility model is as follows: When the vehicle enters the construction site, the single-chip microcomputer 5 controls the capture camera 48 to work. The capture camera 48 identifies the vehicle information and then sends an electrical signal to the single-chip microcomputer 5. The single-chip microcomputer 5 controls the motor 471 to operate. The output shaft of the motor 471 drives the reduction gearbox 472 to work. The reduction gearbox 472 drives the connecting shaft 41 to rotate. The connecting shaft 41 drives the crossbar 43 to deflect upward until the crossbar 43 is perpendicular to the ground. Then the vehicle starts to pass through the barrier. At the same time, the single-chip microcomputer 5 controls the anti-collision radar 6 to work. The anti-collision radar 6 emits electromagnetic waves to detect the vehicle and then sends an electrical signal to the single-chip microcomputer 5. The single-chip microcomputer 5 controls the electric push rod 46 to work. The telescopic end of the electric push rod 46 extends backward, pushing the extrusion ring 453 to move backward. The spring two 454 is compressed under force.

The spring one 444 is compressed under force, and the locking head 445 also moves inward accordingly until the locking head 445 contacts the locking tooth 446 to form a limit. At this time, the connecting shaft 41 is locked. The cross-shaped distributed locking heads 445 make the crossbar 43 more stable. The crossbar 43 can remain vertical for a long time without affecting the equipment. When all vehicles have passed through the barrier, after the anti-collision radar 6 detects no vehicle and obstacle, it sends an electrical signal to the single-chip microcomputer 5. The single-chip microcomputer 5 controls the electric push rod 46 to work. The telescopic end of the electric push rod 46 returns to its original position. The front end of the extrusion ring 453 is not stressed, and the spring two 454 rebounds without stress, driving the extrusion ring 453 back to its original position. As the extrusion ring 453 moves, the top cap 443 loses its restriction. The spring one 444 drives the sliding column 442 and the locking head 445 back to their original positions without stress. The locking head 445 leaves the locking tooth 446. At this time, the connecting shaft 41 loses its restriction. The single-chip microcomputer 5 controls the motor 471 to operate. The motor 471 drives the reduction gearbox 472 to work. The reduction gearbox 472 drives the connecting shaft 41 to rotate, and the crossbar 43 returns to its original position to complete the lowering of the rod. There is an auxiliary self-locking device that can automatically lock the crossbar when the vehicle passes through, maintain the stability of the crossbar, prevent the crossbar from falling and damaging the vehicle and equipment, and automatically release the limit of the crossbar after the vehicle passes.
