[0036] Railway and road crossing intersection, usually will be provided with fence device, mainly used in train passing, warning and preventing vehicles and pedestrians into the railway and railway train collision. Before the train passes, the fence device on the rail is controlled by the railway crossing control system to drop and block in front of the road, play a warning and blocking effect, after the train passes, the rail is raised, allowing vehicles and pedestrians to pass.

[0037] In the prior art, the fence device is composed of a column and a rail rotatably arranged on the column. The rail is driven to rotate around the column by a driving member arranged in the column, so as to realize the effect of lifting to allow passage and dropping to prevent passage. However, since the rail is only connected to the column at one end and the other end is directly supported on the bottom surface or suspended, the blocking effect of the rail is poor. If the vehicle cannot brake in time, the impact force is easy to directly break the rail and enter the railway, which has great safety hazard.

[0038] The utility model provides a fence device 100 of railway and road intersection.

[0039] Please refer to Figure 1 - Figure 5In the embodiment of the utility model, rail device 100 includes rail 1 and two columns, one of which is driving pile 2, and the other is support column 3; rail 1 extends along the first horizontal direction, and the two ends of rail 1 along the first horizontal direction are respectively connecting end 111 and free end 112; driving pile 2 is provided with driving part 25 and gear mechanism 26, the top of driving pile 2 is provided with first installation space 21, first installation space 21 is provided with rotating shaft 22 extending along the second horizontal direction, the second horizontal direction is perpendicular to the first horizontal direction, the opposite ends of rotating shaft 22 are rotationally connected with the opposite sides of the inner wall of first installation space 21 along the second horizontal direction, connecting piece 24 and two first buffer springs 23 are sleeved on rotating shaft 22, two first buffer springs 23 are respectively located on the two sides of connecting piece 24 along the second horizontal direction, and the two ends of each first buffer spring 23 are respectively abutted on connecting piece 24 and the inner wall of first installation space 21, and connecting end 111 is connected with connecting piece 24; support column 3 is spaced apart and arranged on one side of driving pile 2 along the first horizontal direction, the top of support column 3 is provided with second installation space 31, second installation space 31 is provided with connecting shaft 32 extending along the second horizontal direction, support part 34 and two second buffer springs 33 are sleeved on connecting shaft 32, two second buffer springs 33 are respectively located on the two sides of support part 34 along the second horizontal direction, and the two ends of each second buffer spring 33 are respectively abutted on support part 34 and the inner wall of second installation space 31; the top of support part 34 is provided with limiting groove 341 matched with free end 112; driving part 25 can drive rotating shaft 22 to rotate through gear mechanism 26, so as to drive rail 1 to rotate through connecting piece 24, make free end 112 rotate around connecting end 111 through connecting piece 24 on rotating shaft 22, and free end 112 can rotate and be limited in limiting groove 341.

[0040] In this embodiment, the barrier device 100, through the driving component 25 and gear mechanism 26 in the driving pile 2, can drive the barrier 1 to rotate, thereby opening the passage to allow vehicles to pass or closing the passage to prevent vehicles from passing. Supporting posts 3 are set at certain intervals on one side of the driving pile 2. When the barrier 1 is lowered, its free end 112 can be fixed to the supporting post 3, instead of simply suspending in the air or directly supported on the ground. This greatly enhances the stability and strength of the barrier 1, thereby improving its ability to intercept vehicles and preventing the barrier 1 from being easily broken, reducing safety hazards. Furthermore, when the barrier 1 is impacted, the barrier 1 moves along the second horizontal direction under force, and its connecting end 111 drives the connecting... The connector 24 moves on the rotating shaft 22, and the free end 112 drives the support 34 to move on the connecting shaft 32. By setting first buffer springs 23 on the rotating shaft 22 and at both ends of the connector 24, when the connector 24 moves, it stretches one of the first buffer springs 23 and compresses the other buffer spring, thereby effectively absorbing some energy. Similarly, the second buffer spring 33 can also achieve a buffering effect, thereby evenly dispersing the impact force received by the railing 1 and ensuring that the railing 1 is not easily broken. At the same time, the buffering effect of the railing 1 avoids rigid collision between the railing 1 and the vehicle, reduces the vibration generated when the vehicle hits the railing 1, and also reduces the damage caused by the collision between the vehicle and the railing.

[0041] Furthermore, the two first buffer springs 23 facilitate the quick reset of the connecting piece 24, while the two second buffer springs 33 facilitate the quick reset of the supporting piece 34, thereby making it easier for the railing 1 device to continue to be put into use.

[0042] like Figure 1 As shown, the first horizontal direction is the left-right direction, the second horizontal direction is the front-back direction, and the vertical direction is the up-down direction.

[0043] It should be noted that the barrier device 100 is mainly used at level crossings where railways and roads intersect. It is installed on the road to prevent vehicles from entering the railway when a train is passing by. Therefore, in this embodiment, relative to the barrier device 100, the direction of oncoming traffic is forward, and the vehicle is traveling towards the rear in the second horizontal direction.

[0044] It should be noted that the drive unit 25 and the gear mechanism 26 adopt the existing drive motor and reduction gear. The high-speed rotating drive motor drives the rotating shaft 22 to rotate slowly after passing through the reduction gear, thereby slowly raising or lowering the railing 1 to open or close the passage.

[0045] Further, the outer circumferential side of the connecting piece 24 is provided with a connecting head 241, the extending direction of the connecting head 241 is perpendicular to the second horizontal direction, and the connecting end 111 is provided with a connecting hole for inserting the connecting head 241; it can be understood that the connecting head 241 is inserted into the connecting hole, so that the railing 1 is connected with the connecting piece 24, and specifically, the connecting head 241 and the connecting end are also provided with screw holes, and further, bolts are used to cooperate with the screw holes to firmly connect the railing 1 with the connecting piece 24, so as to avoid that the railing 1 falls off from the connecting piece 24 during use.

[0046] In an embodiment, a plurality of sliding grooves 221 are spaced apart along the circumference of the rotating shaft 22, and the plurality of sliding grooves 221 all extend along the second horizontal direction; the connecting piece 24 is provided with a through hole 242 for the rotating shaft 22 to pass through, and the inner wall of the through hole 242 is provided with a protruding strip matched with each sliding groove 221, and the protruding strip extends into the sliding groove.

[0047] It can be understood that the plurality of sliding grooves 221 spaced apart along the circumference of the rotating shaft 22 are matched with the protruding strips on the inner wall of the through hole 242 of the connecting piece 24, which ensures the accurate position and guidance of the connecting piece 24 on the rotating shaft 22. This design makes the connecting piece 24 only move along the predetermined path (i.e. the extending direction of the sliding groove 221), which ensures the reliability of the buffering effect; in addition, through the cooperation of the sliding groove 221 and the protruding strip, the rotation dislocation of the connecting piece 24 on the rotating shaft 22 can be effectively prevented, which ensures that the railing 1 always maintains the correct posture during lifting, and avoids the problems of deviation or jamming of the railing 1 caused by the rotation of the connecting piece 24.

[0048] In an embodiment, the supporting piece 34 includes a connecting portion 342 and a limiting portion 343 connected to the top of the connecting portion 342, the connecting portion 342 is sleeved on the connecting shaft 32, and the two second buffering springs 33 are respectively abutted to the two sides of the connecting portion 342, and the limiting groove 341 is provided on the top of the limiting portion 343; the connecting portion 342 extends from the top of the second mounting space 31 and is supported on the top of the supporting column 3.

[0049] It can be understood that the connecting portion 342 extends from the top of the second mounting space 31 and is supported on the top of the supporting column 3, so that the entire supporting piece 34 is vertically supported on the supporting column 3, which avoids that the connecting shaft 32 is bent or broken due to the increased weight of the supporting piece 34 after the free end 112 of the railing 1 is supported in the limiting groove 341, and increases the structural stability; and the main benefit of such arrangement is to increase the friction area between the supporting piece 34 and the supporting column 3, thereby increasing the friction force, and further dispersing the impact force on the railing 1 through friction.

[0050] Further, the bottom of the connecting portion 342 is supported on the bottom wall of the second mounting space 31.

[0051] In one embodiment, the top edge of the inner wall of the limiting groove 341 is chamfered. The chamfered edge effectively enlarges the size of the top opening of the limiting groove 341, making it easier for the free end 112 to accurately enter the limiting groove 341, thus increasing reliability.

[0052] In one embodiment, the top of the support column 3 has two support plates 35 spaced apart along the second horizontal direction, and a second mounting space 31 is formed between the two support plates 35. The two ends of the connecting shaft 32 are respectively connected to the two support plates 35. The bottom of the support member 34 has two movable grooves 344, and the two movable grooves 344 are located on both sides of the limiting part 343 along the second horizontal direction. The tops of the two connecting plates extend into the two movable grooves 344 respectively.

[0053] Understandably, by setting two support plates 35 spaced apart along the second horizontal direction at the top of the support column 3, a stable frame structure is formed. This not only increases the rigidity of the entire support column 3, but also provides a reliable installation base for the connecting shaft 32. Furthermore, movable slots 344 are opened at the bottom of the support member 34 and on both sides of the limiting part 343 along the second horizontal direction, allowing the tops of the two support plates 35 to extend into the corresponding movable slots 344. This design ensures that the support can move freely within a certain range, while not escaping the restriction of the support plates 35, preventing the support member 34 from falling off the support column 3, thus making it more reliable.

[0054] In one embodiment, the railing 1 includes two horizontal bars 11 and a plurality of vertical bars 12. The two horizontal bars 11 are arranged vertically at intervals, and the plurality of vertical bars 12 are arranged at intervals in a first horizontal direction. The two ends of each vertical bar 12 are respectively rotatably connected to the two horizontal bars 11. The two horizontal bars 11 are, from top to bottom, a first horizontal bar 11a and a second horizontal bar 11b located at the bottom of the first horizontal bar 11a. The two opposite ends of the first horizontal bar 11a are a free end 112 and a connecting end 111, respectively.

[0055] Understandably, the railing 1 is a frame structure composed of two horizontal bars 11 and multiple vertical bars 12, which can significantly improve the structural stability of the entire railing 1, thereby evenly dispersing the impact force when a vehicle hits the railing 1.

[0056] like Figure 4 and Figure 5 As shown, Figure 4 To prevent vehicles from passing, guardrail 1 is supported on drive pile 2 and support column 3. Figure 5 When vehicles are allowed to pass, the guardrail 1 is supported only on the drive pile 2. When the first horizontal bar 11a rotates, the vertical bar 12 rotates relative to the first horizontal bar 11a under the action of gravity. The second horizontal bar 11b changes according to the position of the multiple vertical bars 12.

[0057] In an embodiment, the two posts are provided with a buffer assembly 4 near one side of the railing 1, the buffer assembly 4 comprising a buffer plate 41, a limiting plate 42 and a buffer 43; the limiting plate 42 is spaced apart from the buffer plate 41 along the second horizontal direction, the limiting plate 42 is fixedly connected to the corresponding post, the buffer plate 41 is movably arranged on the corresponding post, and the two ends of the buffer 43 are respectively connected to the buffer plate 41 and the limiting plate 42; when the free end 112 is limited in the limiting groove 341, the two ends of the second cross bar 11b are respectively located on the side of the two buffer plates 41 away from the limiting plate 42.

[0058] It can be understood that by arranging the buffer plate 41, the limiting plate 42 and the buffer 43 near the driving pile 2 and the supporting post 3 on one side of the railing 1, when the railing 1 is impacted by external impact (i.e. when it is impacted by a vehicle in front), the second cross bar 11b abuts against the buffer plate 41, the buffer plate 41 compresses the buffer 43, thereby effectively absorbing and dispersing the impact energy through the buffer 43, and the cooperation of the second cross bar 11b and the buffer assembly 4 further improves the buffering effect on the railing 1. At the same time, the limiting plate 42 is fixedly connected to further limit the second cross bar 11b after buffering, preventing the second cross bar 11b from moving further backward, effectively enhancing the overall interception ability of the railing 1 and making it more reliable.

[0059] Further, the buffer plate 41 is movably connected,

[0060] In an embodiment, the bottom of the two posts is provided with a base 5, the top surface of the base 5 is provided with a moving groove 51, the groove opening of the moving groove 51 is upwardly arranged, the moving groove 51 is provided with a moving seat 52, and the moving seat 52 can move along the second horizontal direction, and the two posts are respectively connected to the two moving seats 52. The two sides of the moving seat 52 along the second horizontal direction are respectively provided with a third buffer spring 53, one end of each third buffer spring 53 abuts against the moving seat 52, and the other end of each third buffer spring 53 abuts against the inner wall of the moving groove 51.

[0061] It can be understood that the third buffer spring 53 is arranged to increase the additional buffer mechanism, when the moving seat 52 slides in the moving groove 51, the third buffer spring 53 can further absorb and disperse the impact energy, improve the overall buffering effect of the railing, reduce the damage to the railing 1. When the railing 1 is impacted, the driving pile 2 and the support column 3 can further absorb and disperse the impact energy through the movement of the moving seat 52 in the moving groove 51, reduce the direct impact on the driving pile 2 or the support column 3, and improve the overall buffering effect of the railing 1. The design of the moving seat 52 makes the railing 1 first realize one-stage buffering through the first buffer spring 23 and the second buffer spring 33 when the railing 1 is impacted, and then the railing 1 drives the driving pile 2 and the support column 3 to move and realize two-stage buffering through the third buffer spring 54, the buffering effect is better; thereafter, when the impact force disappears, the third buffer spring 53 can quickly recover to the original state, push the moving seat 52 back to the initial position, ensure that the stand column can maintain good working condition after being impacted for many times, and improve the reliability and durability of the stand column.

[0062] In an embodiment, two positioning grooves are respectively arranged in the inner walls of the moving groove 51 along the two sides of the first horizontal direction, both of which are in communication with the moving groove 51, and each positioning groove extends along the second horizontal direction. The moving seat 52 is located in the moving groove 51, and the two ends of the moving seat 52 along the first horizontal direction respectively extend into the two positioning grooves.

[0063] It can be understood that the design of the moving groove 51 provides a precise guide path for the moving seat 52, ensures that the moving seat 52 can only move along the predetermined direction when impacted, and the moving groove 51 increases the contact surface of the moving seat 52, so that the friction is larger and the buffering effect is better; at the same time, the design of the sliding groove makes the moving seat 52 not easy to fall out of the moving groove 51, so as to improve the stability of the railing 1.

[0064] In an embodiment, the support column 3 is further provided with a detector 36 and an alarm 37 on one side, and the detector 36 and the alarm 37 are electrically connected. It can be understood that by arranging the detector 36, it can be detected whether there is a vehicle in front, so as to timely remind the vehicle to slow down and stop through the alarm 37 when a train is about to pass on the railway, which is more reliable.

[0065] It should be noted that the detector 36 can adopt a camera, a distance sensor and the like in the prior art, and the alarm 37 can adopt a loudspeaker, a horn, a light alarm 37 and the like in the prior art.

[0066] The above are only exemplary embodiments of the present application, and do not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
