Detailed Implementation

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides a technical solution to achieve this: it includes a control box 1 and a security mechanism 2, the security mechanism 2 being mounted on the control box 1.

[0029] Security mechanism 2 includes a rotating shaft 21, a connecting frame 22, a mounting groove 23, a screw hole 24, a bolt 25, a support plate 26, a guard plate 27, a rotating seat 28, a rotating rod 29, and a ground support 210. The rotating shaft 21 is located at the front and rear ends of the control box 1. The connecting frame 22 is located at the outer end of each rotating shaft 21. The mounting groove 23 extends through the interior of each connecting frame 22. The screw hole 24 extends through the front and rear surfaces of the connecting frame 22 along the straight direction of the mounting groove 23 and is located along the length of the connecting frame 22. At both ends, bolts 25 pass through each screw hole 24. Support plates 26 are set inside each mounting groove 23 and extend outward away from the control box 1. One end of the baffle 27 is set at the end between the two support plates 26 and extends a short distance towards the control box 1. The other end of the baffle 27 extends away from the control box 1. Rotary seats 28 are set one in front and one behind on the side wall of the baffle 27. Rotating rod 29 is set between the two rotating seats 28. Ground support 210 is set on the free end of the rotating rod 29.

[0030] The connecting frame 22 has a rectangular structure and each connecting frame 22 is slightly tilted towards the control box 1. The two opposing support plates 26 are tilted towards each other. The top and bottom of the support plate 26 are obtuse angle structures and the bottom and top are parallel. The baffle 27 has a cuboid structure and the baffle 27 and the rotating seat 28 are integrally formed.

[0031] In detail, the support plate 26 is provided with screw holes 261, 262, bolt grooves 263, bolts 264, and a high-strength spring 265. Screw holes 261 are located at the bottom of the support plate 26, corresponding to the position of each screw hole 24. Screw holes 262 are located at the top of the support plate 26 and the top of the inclined portion of the support plate 26, respectively. Bolt grooves 263 are located on each screw hole 262 located on the inclined portion of the support plate 26. The vertical cross-section of the bolt groove 263 is a right-angled triangle structure, and the bolt groove 263 is recessed into the interior of the support plate 26. Bolts 264 penetrate each screw hole 262 and the support plate 26, extending into the interior of the baffle 27. The high-strength spring 265 is wrapped around the bolts 264 located on the inclined portion of the support plate 26 and is located between the support plate 26 and the baffle 27.

[0032] The front and rear sides of the barrier 27 are provided with reflective strips 271 that form a rectangle along the edge of the barrier 27.

[0033] Analysis of the above content: Adaptable to wide flat passageways: It can meet the protection requirements of 20-22 meter wide flat passageways, solving the common problem of short gate railings that cannot provide protection. It features a double-door design (two doors make a pair), with a single-side railing reaching 11 meters. Through structures such as the A-frame support plate 26, the load is reasonably distributed, ensuring protection for large trucks and container trucks passing through.

[0034] Good structural stability: The connecting frame 22 is slightly inclined, the support plate 26 is in the shape of a herringbone and the top and bottom are obtuse angle parallel structures. With the help of connecting components such as bolts and high-strength springs 265, the overall structural stability and load resistance are improved. The special structure of the bolt groove 263 does not lose the overall rigidity of the support plate 26, and also facilitates the installation and positioning of bolt 264, and strengthens the connection strength between the baffle plate 27 and the support plate 26.

[0035] High visibility at night: Rectangular reflective strips 271 are provided on the front and rear sides of the barrier 27. By utilizing the reflective properties, the visibility of the equipment is improved at night or in low light conditions, enhancing the safety warning effect and reducing the risk of accidental vehicle collisions.

[0036] Easy to disassemble and assemble and flexible to adjust: The support plate 26 and its components can be easily and quickly replaced through the structure of mounting slot 23, screw hole 24, bolt 25, etc.; the setting of rotating seat 28, rotating rod 29 and ground support 210 can adjust the support angle and position of ground support 210 according to the ground conditions to adapt to different site installation needs.

[0037] The following are the structural features of the mechanical components and their supporting strength in this design:

[0038] The security mechanism 2 includes a rotating shaft 21, a connecting frame 22, a mounting groove 23, screw holes 24, bolts 25, a support plate 26, a guard plate 27, a rotating seat 28, a rotating rod 29, and a ground support 210. The specific structural design is as follows:

[0039] Wide-area coverage design: This equipment adopts a double-door design (two doors per pair in actual applications), achieving full-area protection for a 20-22 meter wide flat passageway through symmetrically distributed security mechanisms 2. The pivot 21 is located at both ends of the control box 1, with a connecting frame 22 connected to the outer end of the pivot 21 and extending outwards. Support plates 26 are embedded inside the connecting frame 22 via mounting slots 23 and extend outwards away from the control box 1. A barrier 27 is connected at one end to the ends of the two support plates 26, and extends away from the control box 1 at the other end. A single barrier 27 can reach a length of 11 meters, meeting the protection requirements for wide-body vehicles such as large trucks and container trucks.

[0040] The supporting strength enhancement structure: the connecting frame 22 is rectangular and slightly inclined towards the control box 1, and the two opposing support plates 26 are in a "V" shape and inclined towards each other to form a triangular stable support structure, which can effectively disperse the lateral force (such as the impact force of a vehicle collision) borne by the barrier plate 27.

[0041] The top and bottom of the support plate 26 are both obtuse angle structures and remain parallel, which avoids stress concentration in the sharp angle structure and optimizes the force transmission path through the tilt angle. Its surface is provided with screw hole 261, screw hole 262, bolt groove 263, bolt 264 and high-strength spring 265. Screw hole 261 corresponds to screw hole 24 of the connecting frame 22. The support plate 26 and the connecting frame 22 are fixed by bolt 25 to ensure connection rigidity. Screw hole 262 penetrates the support plate 26 through bolt 264 and extends into the interior of the baffle 27. With the high-strength spring 265 wrapped around bolt 264 (located between the support plate 26 and the baffle 27), it can buffer instantaneous impact force and reduce structural deformation.

[0042] Bolt groove 263 is located at bolt hole 262 on the inclined part of support plate 26. Its vertical cross section is a right triangle and is recessed into the support plate 26. It does not damage the overall rigidity of support plate 26, and can limit bolt 264 to prevent loosening.

[0043] The rotating seat 28, rotating rod 29 and ground support 210 on the side wall of the barrier 27 form auxiliary support: the rotating rod 29 can rotate around the rotating seat 28, and the ground support 210 contacts the ground. The support angle is adjusted according to the flatness of the site to further improve the stability of the barrier 27 in the unfolded state.

[0044] The following are the safety control and auxiliary protection measures for the shunting system in this plan:

[0045] Shunting system safety inter-control mechanism: The linkage control module of control box 1 is connected to the shunting operation system via wired or wireless means to realize the following inter-control functions:

[0046] When the shunting system detects that a train is approaching the level crossing (e.g., by obtaining the train's position through track circuits or Beidou positioning), it will send an "interception command" to the control box 1. The control box 1 will drive the rotating shaft 21 to rotate, causing the connecting frame 22, support plate 26 and barrier plate 27 to be lowered synchronously until the barrier plate 27 is fully extended and firmly supported by the ground support 210, forming a physical isolation barrier that prohibits pedestrians and vehicles from passing.

[0047] Once the train passes through the level crossing and the shunting system confirms that the track is clear, a "release command" is sent. Control box 1 drives shaft 21 to rotate in the opposite direction, and the barrier 27 retracts, allowing passage. At the same time, the control box 1 has a built-in status monitoring unit that can detect the unfolded / retracted position of the barrier 27, the strength of bolt connections, etc. in real time. If a structural abnormality occurs (such as the barrier not being fully lowered), an alarm signal will be sent to the shunting system, suspending the train passage command until the fault is cleared.

[0048] Auxiliary protective measures: The front and rear sides of the guardrail 27 are provided with reflective strips 271 that form a rectangle along the edge. At night or in low light conditions, they can form a bright warning border by reflecting vehicle lights, improving the visibility of the equipment and reducing the risk of accidental collision.

[0049] The control box 1 is equipped with an audible and visual alarm device on the outside. During the opening / closing of the barrier 27, a warning light and a prompt sound (such as "Caution, barrier is in motion") are emitted simultaneously to remind surrounding personnel and vehicles to avoid the area.

[0050] Working Principle: In practical applications, the device in this scheme exists in pairs, employing a double-door design to reduce the load on one side. Control box 1 provides the control foundation for the equipment. Security mechanism 2 is connected to control box 1 via rotating shaft 21. Connecting frame 22 uses bolt 25 and mounting groove 23 to install and fix support plate 26. Support plate 26 is distributed in a herringbone pattern and is connected to barrier plate 27 via bolt 264, high-strength spring 265, etc. Barrier plate 27 can adjust the ground support 210's ground support state using rotating seat 28 and rotating rod 29. The double-door design, combined with the structure of each component, achieves safety protection for wide flat passageways. Reflective strip 271 enhances nighttime visibility.

[0051] The components of this utility model are: 1-control box; 2-security mechanism; 21-rotating shaft; 22-connecting frame; 23-mounting groove; 24-screw hole one; 25-bolt one; 26-support plate; 261-screw hole two; 262-screw hole three; 263-bolt groove; 264-bolt two; 265-high-strength spring; 27-barrier; 271-reflective strip; 28-rotating seat; 29-rotating rod; 210-ground support. These components are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that the passageway width is relatively wide, involving the passage of large trucks and container trucks, generally around 20-22 meters. However, the common parking lot gate barriers are only about 6 meters high, which cannot meet the safety protection requirements of the passageway. This utility model adapts to 20-22 meter wide flat passageways with a double-door design, a herringbone support plate to ensure structural stability, reflective strips to improve nighttime visibility, and flexible installation and adjustment. It effectively solves the protection problem of wide flat passageways and enhances safety performance and site adaptability.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
