Liftable gangway machine

Abstract

This utility model discloses a liftable toll gate, including a barrier for intercepting large vehicles and a lifting mechanism capable of raising the barrier by 90°. A secondary barrier for intercepting small vehicles is installed at the bottom of the barrier, and a lifting structure for driving the secondary barrier to rise and fall is installed on the outer wall of the barrier. The lifting structure includes a crank and a rotating motor that drives the crank to swing. This utility model, by adding an independently liftable secondary barrier at the bottom of the barrier, with a length of 1 / 3 of the main barrier, only requires driving the secondary barrier to intercept small vehicles, eliminating the need to raise the main barrier entirely. Compared to traditional methods that require driving a barrier arm of 3 meters or more, this reduces motor energy consumption and is particularly suitable for scenarios where small and large vehicles frequently switch between each other. The secondary barrier achieves parallel lifting and lowering through the crank mechanism and rotating motor, with a lifting speed much faster than the traditional method of raising the entire barrier, avoiding traffic delays caused by slowly raising the main barrier and improving the efficiency of toll station traffic.

Description

Technical Field

[0001] This utility model relates to the field of transportation, specifically a liftable gate closing mechanism. Background Technology

[0002] A toll gate node, commonly known as a toll gate machine, is a common piece of equipment installed at the toll island of a toll station on a road or bridge. Traditional toll gate nodes use manual or electric modes to push a mechanical barrier arm to open or close or raise and lower, thereby enabling the toll lane to be closed or opened.

[0003] However, once the traditional barrier gate is installed and fixed, the height of the barrier arm for opening / closing the lane is fixed. If a small vehicle can pass under the barrier arm, the height restriction function of the lane cannot be completed.

[0004] A search revealed a lifting multi-functional gate access control device disclosed in patent application publication number CN222139850U. The device includes a chassis with a drive mechanism inside. The drive mechanism has a horizontally arranged drive shaft, with the distal end of the drive shaft extending outward from a clearance hole on the rear surface of the chassis. A railing is connected to the distal end of the drive shaft via a connecting member, which can drive the railing to rotate vertically to both vertical and horizontal states. The clearance hole has an overall elongated structure and is arranged along the vertical direction of the chassis.

[0005] While the aforementioned patent can raise and lower the barrier arm via a drive mechanism to intercept small vehicles, the drive mechanism needs to move the entire barrier arm up and down frequently when switching between identifying small and large vehicles, which is energy-intensive. Furthermore, the barrier arm is usually over 3 meters long, and the drive mechanism needs to slowly and smoothly raise the barrier arm during the switching process, resulting in slow height switching efficiency and affecting traffic efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a liftable barrier gate. By setting a secondary bar at the bottom of the barrier, with the length of the secondary bar set to one-third of the length of the barrier and located in the middle of the barrier, it can block small vehicles. Through the rotation of a motor and a crank structure, the secondary bar can be quickly raised and lowered in parallel. When the height of the vehicle is lower than the barrier, the barrier does not need to be raised, only the secondary bar needs to be retracted, which can reduce energy consumption and solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a liftable barrier gate, comprising a barrier for intercepting large vehicles and a lifting mechanism capable of raising the barrier gate by 90°, wherein a secondary bar for intercepting small vehicles is installed at the bottom of the barrier gate, and a lifting structure for driving the secondary bar to rise and fall is installed on the outer wall of the barrier gate;

[0008] The lifting structure includes a crank and a rotating motor that drives the crank to swing. One end of the crank is rotatably connected to one end of the auxiliary rod through a rotating shaft. The outer wall of the railing is provided with a fixed seat for mounting the rotating motor.

[0009] Preferably, the lifting structure further includes a swing arm that limits the other end of the auxiliary rod. One end of the swing arm is rotatably connected to the auxiliary rod via a rotating shaft, and the other end of the swing arm is fixed with a rotating rod. A first bearing seat is installed on the outer wall of the railing via screws, and the rotating rod is rotatably connected in the first bearing seat via a bearing.

[0010] Preferably, the length of the secondary bar is set to one-third of the length of the railing, and the secondary bar is parallel to the railing.

[0011] Preferably, a warning sign is fixed to the middle of the secondary pole by screws, and the warning sign is located on the side of the secondary pole away from the railing.

[0012] Preferably, the fixing base includes a housing, and both sides of the housing are provided with extension sleeves that can increase the contact surface with the outer wall of the railing. After the extension sleeves are fitted onto the outer wall of the railing, they are fixed to the railing by screws.

[0013] Preferably, the outer casing is provided with a second bearing seat for mounting the crank rod, and the inner cavity of the outer casing is provided with an integrally formed geometric platform. The second bearing seat is mounted on one side of the geometric platform, and the rotating motor is fixed on the other side of the geometric platform. The output end of the rotating motor passes through the geometric platform through a rotating shaft and is fixedly connected to the crank rod.

[0014] Preferably, the bottom of the pedestal forms a groove for placing the railing, and two sets of extension sleeves are located on both sides of the groove.

[0015] Preferably, the bottom of the housing is provided with a clearance groove for the crank to swing, and the two ends of the housing are fixed with end plates by screws.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model adds an independently liftable auxiliary bar at the bottom of the guardrail, with a length of 1 / 3 of the main guardrail. Only the auxiliary bar needs to be driven to intercept small vehicles, eliminating the need to raise the entire main guardrail. Compared to traditional methods that require driving a guardrail arm over 3 meters long, this reduces motor energy consumption and is particularly suitable for scenarios where small and large vehicles frequently switch between each other.

[0018] 2. The auxiliary pole of this utility model achieves parallel lifting and lowering through a crank mechanism in conjunction with a rotating motor. The lifting and lowering speed is faster than the traditional overall lifting method, which can avoid traffic delays caused by the slow lifting of the main pole and improve the traffic efficiency of the toll station.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a liftable gate barrier, including a barrier 1 for intercepting large vehicles and a lifting mechanism 2 capable of raising the barrier 1 by 90°. The lifting mechanism 2 is the same as the lifting equipment in existing gate barrier technologies, capable of driving the barrier 1 to rotate 90° to raise the barrier 1. A secondary bar 3 capable of intercepting small vehicles is installed at the bottom of the barrier 1. Figure 1 As shown, the auxiliary pole 3 is located below the railing 1. The outer wall of the railing 1 is equipped with a lifting structure 4 that drives the auxiliary pole 3 to rise and fall. When it is necessary to intercept small vehicles, the auxiliary pole 3 descends through the lifting structure 4. When the interception state is lifted, the auxiliary pole 3 rises in parallel through the lifting structure 4 and approaches the railing 1.

[0026] The lifting structure 4 includes a crank 401 and a rotary motor 402 that drives the crank 401 to swing. The output end of the rotary motor 402 is fixed to the crank 401. When the output end of the rotary motor 402 rotates, it drives the crank 401 to rotate. One end of the crank 401 is rotatably connected to one end of the auxiliary rod 3 via a rotating shaft. The outer wall of the railing 1 is provided with a fixing seat 403 for mounting the rotary motor 402. The fixing seat 403 is used to mount the rotary motor 402, such as... Figure 1 As shown, the rotating motor 402 is set at one end of the railing 1 near the lifting machine 2 to reduce the influence of the gravity of the lifting structure 4 on the balance of the railing 1.

[0027] The lifting structure 4 also includes a swing arm 404 that limits the other end of the auxiliary rod 3. One end of the swing arm 404 is rotatably connected to the auxiliary rod 3 via a rotating shaft, and the other end of the swing arm 404 is fixed with a rotating rod 405. A first bearing seat 406 is installed on the outer wall of the railing 1 via screws, and the rotating rod 405 is rotatably connected to the first bearing seat 406 via a bearing. By rotating the motor 402, the crank rod 401 is driven to rotate. At this time, the crank rod 401 pushes the swing arm 404 to rotate via the auxiliary rod 3. The swing arm 404 and the rotating rod 405 are of the same length, so that the auxiliary rod 3 moves upward in parallel.

[0028] The length of the secondary pole 3 is set to one-third of the length of the railing 1, and the length of the secondary pole 3 is controlled to not exceed 1.5m. This is to avoid the secondary pole 3 from drooping at the end away from the curved pole 401 due to excessive weight, which would affect the parallel rise of the secondary pole 3. The secondary pole 3 is parallel to the railing 1, and the secondary pole 3 rises and falls in parallel with the railing 1, so that the warning sign 5 is facing the vehicle.

[0029] A warning sign 5 is fixed to the middle of the secondary pole 3 by screws. The warning sign 5 is located on the side of the secondary pole 3 away from the guardrail 1. The warning sign 5 is installed on the secondary pole 3. When a small vehicle is blocked, the warning sign 5 faces the small vehicle. When a large vehicle is blocked, the secondary pole 3 rises, and the warning sign 5 is located in the middle of the guardrail 1, so that the warning sign 5 can face both large and small vehicles.

[0030] The fixing base 403 includes a housing 4031. Both sides of the housing 4031 are provided with extension sleeves 4032 that can increase the contact surface with the outer wall of the railing 1. By providing extension sleeves 4032, the stability of the fixing between the fixing base 403 and the railing 1 is improved. After the extension sleeves 4032 are fitted onto the outer wall of the railing 1, they are fixed to the railing 1 by screws.

[0031] The outer casing 4031 is provided with a second bearing seat 4033 for mounting the crank 401, and the inner cavity of the outer casing 4031 is provided with an integrally formed geometric platform 4034, such as... Figure 2As shown, by setting up a shaped platform 4034, it is easy for the fixing seat 403 to be locked above the railing 1. The second shaft seat 4033 is installed on one side of the shaped platform 4034, and the rotating motor 402 is fixed on the other side of the shaped platform 4034. The output end of the rotating motor 402 passes through the shaped platform 4034 through the rotating shaft and is fixedly connected to the curved rod 401.

[0032] The bottom of the pedestal 4034 forms a groove 4035 for placing the railing 1, and two sets of extension sleeves 4032 are respectively located on both sides of the groove 4035. Figure 2 As shown, the fixing seat 403 is secured above the railing 1 by the groove 4035, making it easy to install and remove.

[0033] The bottom of the outer casing 4031 is provided with a relief groove 4036 for the crank rod 401 to swing. The two ends of the outer casing 4031 are fixed with end plates 4037 by screws. The end plates 4037 are used to seal the two ends of the outer casing 4031 and protect the internal rotating motor 402.

[0034] When in use, the height of the secondary pole 3 is set to 1.2-2m, which is the common height for small vehicles, and the length of the secondary pole 3 is set to 1-1.5m. The height of the guardrail 1 is set to 2-4m, which is the common height for large vehicles.

[0035] The following example uses a secondary pole 3 with a height of 1.5m, a length of 1m, and a railing 1 with a length of 3m:

[0036] When the vehicle is within 1.2-2m, the initial position of the auxiliary pole 3 is as follows: Figure 1 As shown, this is the interception state. When it is necessary to release the interception, the rotary motor 402 is activated, driving the crank 401 to rotate, which in turn drives the auxiliary rod 3 to push the swing arm 404 to the right. Figure 3 This is a diagram showing the position of the auxiliary lever 3 when it is half-raised, until the auxiliary lever 3 rises to... Figure 4 At the indicated position, the blockage is lifted, allowing small vehicles to pass. At this point, the height of barrier 1 is higher than that of small vehicles, so it does not need to be raised.

[0037] When the vehicle is 2-4m or above 4m, the auxiliary rod 3 rises: the rotary motor 402 starts, driving the crank 401 to rotate, which in turn drives the auxiliary rod 3 to push the swing arm 404 to the right until the auxiliary rod 3 rises to... Figure 4 At the indicated location, the blockage is released. Simultaneously, the lifting machine 2 raises the barrier 1 upwards. The lifting drive within the lifting machine 2 is the same as existing technology and will not be described further. The raising action of the auxiliary bar 3 can be synchronized with the raising action of the barrier 1, improving passage efficiency.

[0038] Compared to traditional single-pole toll gate machines, this gate machine has a shorter secondary pole 3, faster lifting speed, and does not require the entire barrier 1 to move up and down. Furthermore, it eliminates the need to raise barrier 1 when small vehicles pass, thus reducing energy consumption. It is particularly suitable for high-traffic toll stations where small and large vehicles frequently switch between traffic, enabling energy reduction and improved traffic efficiency while simultaneously intercepting both types of vehicles.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
