Description

Technical Field

[0001] The utility model relates to the technical field of construction site gate opening and closing systems, in particular to an automatically opening and closing construction site gate. Background Art

[0002] With the continuous development of urban construction, various construction sites also exist in different areas of the city. A construction site refers to a place where a construction project is being developed and civil engineering is being carried out. Its scope is often enclosed by fences, barbed wire or walls to restrict the entry and exit of personnel, materials, machinery and vehicles. The construction site is guarded by project participants. In order to ensure safety, personnel entering and exiting may need to register their ID cards or face recognition. Vehicles entering must also be verified by license plate number to confirm that they are registered vehicles or construction vehicles that need to enter before they can enter.

[0003] In order to facilitate the entry of personnel and vehicles, construction sites are currently equipped with construction gates, but the common construction site gates are manually controlled, which has many inconveniences. First, the intelligence is poor, and each entry and exit switch needs to be manually opened and closed, which increases the workload of the guard; second, the manual control is not timely and fast enough. If the door is not opened in time, construction vehicles may be blocked at the construction site gate, causing traffic congestion on the main road. If the door cannot be closed in time, pedestrians passing by may enter the site, posing a hidden danger to the safety management of the construction on the site; third, long-term and high-frequency manual control of the door opening and closing will cause the guard to be tired and exhausted. If there is bad weather, the guard may make mistakes in operation, which may also cause accidental injuries to personnel.

[0004] As an improvement, the license plate number recognition device of the unattended parking lot is combined with the switch of the construction site gate. The license plate number recognition device is used to identify vehicles parked at the entrance of the gate to confirm whether they are work vehicles on the site. After identification, if it is a work vehicle on the site, the license plate recognition system will transmit a start signal to the gate opener of the gate, thereby starting the gate to open, and the vehicle can enter. The gate will close after the vehicle has completely passed.

[0005] However, there are still some problems with the current automated gates. Because the construction site gate needs to accommodate the entry of some large machinery, the gate width is relatively large, resulting in the gate width and height also needing to be set high. The overall size and weight of the gate are large, so the speed is slow when opening and closing, which still causes the problem of vehicle congestion at the gate. In addition, when vehicles enter frequently, the slow opening and closing of the gate will also affect the efficiency of vehicle entry and exit. Utility Model Content

[0006] In view of the deficiencies existing in the prior art, the utility model provides an automatically opening and closing construction site gate, which solves the problems existing in the prior art of slow opening and closing speed of the gate, resulting in vehicle congestion and low entry and exit efficiency.

[0029] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0030] Example:

[0031] like Figure 1 As shown, the embodiment of the utility model proposes an automatically openable and closeable construction site gate, comprising a gate body 1, a vehicle width detection component 2, a license plate recognition component 3 and a through detection component 4. The gate body 1 is arranged at the construction site gate, completely closing the road entrance corresponding to the gate, the vehicle width detection component 2 and the license plate recognition component 3 are arranged outside the gate body 1, and the through detection component 4 is arranged at an adjacent position inside the gate.

[0032] In this embodiment, the door body 1 includes a door frame, an upper door body 11 arranged in the door frame, and two symmetrically arranged lower door bodies 12. The upper door body 11 and the lower door body 12 can be combined and spliced ​​into a complete door body structure without gaps in a vertical state. A driving component is also provided on the door frame, and the driving component drives the upper door body 11 and the lower door body 12 to move respectively, thereby opening or closing.

[0033] like Figure 2As shown, in this embodiment, the door frame includes a first door post and a second door post that are symmetrically arranged on the left and right, and the first door post and the second door post both include a vertical limit post 7 and a horizontal limit post 8 that are arranged vertically up and down, and the vertical limit post 7 and the horizontal limit post 8 are both provided with a hollow portion along the vertical plane where the upper door body 11 and the lower door body 12 are located, that is, the hollow portion separates the vertical limit post 7 and the horizontal limit post 8 into two halves along the vertical direction, thereby forming a space for the upper door body 11 and the lower door body 12 to be placed and moved through. That is, the first door post and the second door post are respectively arranged on both sides of the gate, and the space is used for vehicles to pass through, and one group of the vertical limit post 7 and the horizontal limit post 8 in the first door post or the second door post is a symmetrical structure that is divided into two halves along the road driving direction, and the upper door body 11 and the lower door body 12 are arranged between this group of symmetrical structures.

[0034] like Figure 3 As shown, in a further scheme, the driving assembly includes a first gear 71 arranged on the vertical limit column 7 and a second gear 81 arranged on the horizontal limit column 8, and the first gear 71 and the second gear 81 are respectively arranged in groups on the inner walls of the first door column and the second door column on both sides of the hollow portion, so as to be symmetrically arranged relative to the upper door body 11 and the lower door body 12, and the first gear 71 and the second gear 81 are respectively connected to the first motor and the second motor.

[0035] like Figure 4 , Figure 5 As shown, correspondingly, the first gear 71 is axially arranged horizontally, wherein the tooth surface of the first gear 71 faces the upper door body 11, and the upper door body 11 is provided with vertical first racks 111 on the front and rear surfaces corresponding to the first door column and the second door column on both sides, and the tooth surface of the first rack 111 is located on the vertical planes parallel to the two sides of the upper door body 11. That is, the first gears 71 arranged on the opposite surfaces of a group of vertical limit columns 7 are respectively located on the front and rear surfaces of the upper door body 11, and are respectively engaged with the two first racks 111, so that the rotation of the first gear 71 drives the first rack 111 to move up and down, thereby driving the upper door body 11 to move in the vertical direction to achieve the function of opening or closing. Preferably, the vertical limit column 7 is also provided with a limit plate, and the limit plate is located on the vertical end surfaces on both sides of the vertical limit column 7, thereby connecting the hollow part, forming a closed structure on both sides of the end surface, thereby limiting the two sides of the upper door body 11 to prevent it from horizontal displacement.

[0036] Correspondingly, the second gear 81 is axially arranged horizontally, and the end face of the second gear 81 faces the lower door body 12. The lower door body 12 is symmetrically provided with a horizontal second rack 121 on the front and rear surfaces, and the tooth surface of the second rack 121 is located on the horizontal plane of the top. That is, the second gear 81 is arranged on the upper part of the second rack 121 and meshes with it, thereby driving the second rack 121 and the lower door body 12 to move in the horizontal plane. Since there are two lower door bodies 12, they are driven by the second gears 81 on the first door post and the second door post respectively. When the two lower door bodies 12 are away from each other, the gate body 1 is opened, and when they are close to each other, they are closed. Preferably, two or more limiting rollers 82 are arranged side by side in the horizontal direction on the horizontal limiting column 8, and the limiting rollers 82 are arranged on the upper part of the second gear 81 and are axially arranged vertically. A group of horizontal limiting columns 8 are symmetrically provided with limiting rollers 82 on both sides of the hollow part, thereby limiting the lower door body 12 sandwiched therebetween to prevent the lower door body 12 from being offset during movement.

[0037] In addition, the bottom of the lower door body 12 is in sliding contact with the ground. In this embodiment, a pulley 9 is provided at the bottom of the lower door body 12, and a guide rail matching the pulley 9 can also be buried in the ground. This makes the lower door body 12 move more smoothly and reduces the probability of it getting stuck.

[0038] In this embodiment, the vehicle width detection component 2 is arranged on the outer side of the gate body 1, and the vehicle width detection component 2 detects the width of the vehicle that needs to enter the gate body 1, and judges whether one or two lower doors 12 in the gate body 1 need to be opened according to its width. Specifically, the vehicle width detection component 2 includes rangefinders symmetrically arranged on both sides of the road outside the gate body 1. In this embodiment, a laser rangefinder is preferably used. The rangefinder is relatively arranged and detects the distance between it and the vehicle passing on the road at the same time. Because the distance between the two rangefinders is fixed and known during installation, and the two rangefinders can respectively detect the distance between them and the two sides of the vehicle, then the total distance between the two rangefinders minus the distance between the two rangefinders and the vehicle respectively detected by the two rangefinders, the result is the vehicle width. In this embodiment, the rangefinder continuously detects when the vehicle passes by, so as to obtain the maximum width of the vehicle. At the same time, multiple rangefinders can also be arranged in parallel in the vertical direction to avoid the inconsistency of the upper and lower widths of some vehicles, so as to more accurately obtain the maximum width of the vehicle and avoid the collision between the vehicle and the gate body 1.

[0039] The license plate recognition component 3 is arranged on the outer side of the gate body 1, outside the road and facing the entrance direction of the gate body 1, and is used to detect and recognize the license plate number of the vehicle. When the registered license plate number is detected, the gate body 1 is opened, otherwise it is not opened. The license plate recognition component 3 can adopt any similar technical product on the market, and it only needs to be able to collect license plate data for recognition, and then send a signal to the electric control switch of the gate body 1. It will not be described here.

[0040] In the embodiment of the utility model, the detection component 4 is arranged close to the gate body 1, and when the detection component detects that there is an object at the gate body 1, the gate body 1 is not closed. Furthermore, the detection component 4 includes an infrared probe horizontally arranged parallel to the gate body 1, and the infrared probe is perpendicular to the driving direction of the vehicle entering the gate body 1. When the infrared probe can detect a larger infrared feature, it means that there is still a certain area of ​​the vehicle below the gate body 1; when the vehicle completely enters the gate body 1, the infrared probe cannot detect the larger infrared feature, and at this time a signal can be sent to the electric control switch of the gate body 1 to control the gate body 1 to close. Preferably, the infrared probe is arranged on the inner side of the gate parallel to the gate body 1, so as to leave a certain margin to ensure that it will not be closed until the vehicle is completely entered.

[0041] As a fully automated system, the embodiment of the utility model also includes a separately arranged processor, which includes an MCU, can receive and send electrical information and process data, and is electrically connected to the drive motor in the gate body 1, the rangefinder in the vehicle width detection component 2, the license plate recognition component 3 and the infrared probe in the detection component 4, so as to collect various information and control the opening and closing of the gate body 1 after comprehensive judgment.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
