[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a safety protection device for railway level crossings, including a fixed shell 1, a control plate 2 installed on the side of the fixed shell 1, a rotating rod 3 rotatably connected to the inner wall of the control plate 2, a collar 5 fixedly connected to the surface of the rotating rod 3, a first torsion spring 6 sleeved on the surface of the rotating rod 3, the two ends of the first torsion spring 6 being fixedly connected to the collar 5 and the control plate 2 respectively, a railing 4 fixedly connected to the surface of the rotating rod 3, a blocking device 7 provided inside the control plate 2, and an adjusting device 8 provided inside the fixed shell 1.
[0030] The following section will describe in detail the specific settings and functions of the blocking device 7 and the adjusting device 8.
[0031] Reference Figures 1-3 As shown in this embodiment: the blocking device 7 includes a stabilizing plate 74, which is fixedly connected to the inner wall of the control plate 2. A rotating rod 76 is rotatably connected to the inner wall of the stabilizing plate 74. A gear 77 is fixedly connected to the end of the rotating rod 76 away from the rotating rod 3. A toothed block 72 is installed on the lower surface of the railing 4, and the toothed block 72 meshes with the gear 77. By setting the stabilizing plate 74, the gear 77 can be installed, and the stability of the gear 77 during rotation can be improved. By setting the toothed block 72 and the gear 77, the speed of the railing 4 resetting can be slowed down. A bent rod 71 is fixedly connected to the lower surface of the railing 4. The end of the bent rod 71 away from the railing 4 is fixedly connected to the toothed block 72. Eight ball bearings 73 are installed on the lower surface of the toothed block 72, and all eight ball bearings 73 are rotatably connected to the inner wall of the toothed block 72. By setting the bent rod 71, the toothed block 72 can be connected to the railing 4. By setting the ball bearing 73, the friction of the toothed block 72 during movement can be reduced, thereby reducing frictional damage to the toothed block 72 and improving the smoothness of its movement.
[0032] A rotating plate 79 is fixedly connected to the end of the rotating rod 76 away from the gear 77. An "L"-shaped plate 75 is rotatably connected to the side of the rotating plate 79 away from the rotating rod 76. The "L"-shaped plate 75 is fixedly connected to the stabilizing plate 74. By setting the "L"-shaped plate 75, the stability of the connection between the rotating rod 76 and the stabilizing plate 74 can be improved, as can the rotational stability of the rotating rod 76. A second torsion spring 78 is fitted on the surface of the rotating rod 76. The two ends of the second torsion spring 78 are fixedly connected to the rotating plate 79 and the stabilizing plate 74, respectively. By setting the rotating plate 79, the installation of the second torsion spring 78 is facilitated, and the second torsion spring 78 can limit the rotation of the rotating rod 76.
[0033] Reference Figure 1 and Figure 2 as well as Figure 4 As shown, specifically, the adjusting device 8 includes an adjusting rod 82, which is rotatably connected to the inner wall of the fixed housing 1. A circular plate 81 is fixedly connected to the end of the adjusting rod 82 away from the control plate 2. The circular plate 81 is rotatably connected to the lower surface of the fixed housing 1. A clamping plate 83 is fixedly connected to the surface of the adjusting rod 82, and the clamping plate 83 is rotatably connected to the inner wall of the fixed housing 1. By setting the adjusting rod 82, the circular plate 81, and the clamping plate 83, the angle of the fixed housing 1 can be easily adjusted after it is placed in the installation position.
[0034] A top plate 84 is fixedly connected to the end of the adjusting rod 82 away from the circular plate 81, and a screw 85 is threaded into the inner wall of the top plate 84. By setting the top plate 84, the screw 85 can be connected to the adjusting rod 82, and the screw 85 can be used to easily restrict the top plate 84. A connecting plate 86 is fixedly connected to the end of the screw 85 near the fixed housing 1, and a rubber pad 87 is glued to the side of the connecting plate 86 away from the screw 85. By setting the connecting plate 86, the screw 85 and the rubber pad 87 can be easily connected, and the rotation of the screw 85 can be easily restricted.
[0035] Working principle: When using the railway level crossing safety protection device, the control plate 2 drives the guardrail 4 to rotate, thereby blocking the railway level crossing. When a vehicle is stuck between the guardrails 4 on both sides of the railway level crossing, the vehicle's backward movement pushes the guardrail 4 and the rotating rod 3 to rotate. The rotation of the rotating rod 3 drives the collar 5 to rotate synchronously. At the same time, the bent rod 71 drives the toothed block 72 to rotate and move closer to the control plate 2. By setting the ball bearing 73, friction damage between the toothed block 72 and the control plate 2 can be avoided as much as possible. The rotation of the toothed block 72 causes the gear 77 to drive the rotating rod 76 to rotate on the inner wall of the stabilizing plate 74 and the surface of the "L"-shaped plate 75. When the toothed block 72 rotates away from the gear 77, under the action of the second torsion spring 78, the gear 77 rotates back to its original position. When the vehicle releases the guardrail... After the push of lever 4, under the action of the elastic force of the first torsion spring 6, the toothed block 72 rotates and approaches the gear 77. At this time, the elastic force of the first torsion spring 6 and the elastic force of the second torsion spring 78 form a resistance. Since the elastic force of the second torsion spring 78 is less than the elastic force of the first torsion spring 6, the railing 4 can slowly rotate and reset. By setting the rotating plate 79, the rotating rod 76 can be rotated. By setting the blocking device 7, after the vehicle pushes the railing 4 to rotate, the elastic force of the second torsion spring 78, in conjunction with the gear 77 and the toothed block 72, can slow down the reset speed of the railing 4, thereby avoiding the situation where the vehicle surface is scratched due to the reset of the railing 4 as much as possible.
[0036] When installing the railway level crossing safety protection device, first move the fixed shell 1 to the required installation position. Then, rotate the screw 85 to make it rotate on the inner wall of the top plate 84, thereby controlling the connecting plate 86 and the rubber pad 87 to move away from the fixed shell 1, releasing the restriction on the adjusting rod 82. Then, rotate the fixed shell 1 to make it rotate on the surface of the circular plate 81 and the clamping plate 83, thereby adjusting the angle of the fixed shell 1. After adjusting the fixed shell 1, rotate the screw 85 to make the rubber pad 87 move closer to the fixed shell 1, which will restrict the adjusting rod 82. Then, fix the fixed shell 1. By setting the adjusting device 8, during the installation of the railway level crossing safety protection device, after moving the fixed shell 1 to the required installation position, it is convenient to rotate the fixed shell 1, thereby facilitating the adjustment of the angle of the fixed shell 1 and the installation of the railway level crossing safety protection device.
