Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of road traffic management equipment, and specifically to a road anti-collision height-limiting frame. Background Art
[0002] The height-limiting frame structure is generally applied to positions with height restrictions on vehicle passage such as bridges and tunnels. Its function is to block the passage of over-height vehicles. The common structure of the height-limiting frame is generally a portal shape, composed of two columns and a height-limiting crossbeam at the top, and it intercepts vehicles by itself. The height-limiting frame is mainly used for the portal frame at the entrance of bridges, culverts, and tunnels, generally welded by steel structures, and plays a role in protecting bridges, culverts, and tunnels. When a vehicle hits the height-limiting frame, it will be blocked by the height-limiting frame and thus stop moving forward.
[0003] Most of the existing height-limiting frames are of an integral crossbeam shape. When colliding with large vehicles, a huge impact force will be generated between the height-limiting frame and the large vehicle, which will cause damage to the vehicle and may pose a certain threat to the personal safety of the driver. Summary of the Invention

A first chute is formed at the top of the support connection mechanism. The number of the limiting rods is two. A first slider is fixedly connected to the bottom of the limiting rod. The first slider is slidably connected to the support connection mechanism in the first chute. A number of uniformly distributed buffer springs are detachably connected between the two limiting rods. The number of the buffer mechanisms is two, and the buffer mechanisms are located on one side of the support connection mechanism. A second chute is formed on the buffer mechanism. The second chute is communicated with the first chute, and the sizes of the second chute and the first chute are the same. A clamping positioning plate is fixedly connected to the outer wall of one side of the buffer mechanism. A number of uniformly distributed blocking plates are arranged in the second chute. The blocking plates are fixedly welded to the buffer mechanism. Every two blocking plates form a group, and an anti-collision buffer layer is clamped and connected between each group of blocking plates. A transverse blocking rod is arranged on the buffer mechanism. The transverse blocking rod penetrates through the buffer mechanism and is clamped and connected with the clamping positioning plate. One end of the buffer mechanism far away from the support connection mechanism is detachably connected with a high-strength fixing plate.
[0008] As a further scheme of the present invention: Connecting plates are fixedly connected to both sides of the bottom of the support connection mechanism. Connection holes are formed in the connecting plates. A fixing rod is fixedly connected to the bottom of the support connection mechanism. One end of the fixing rod far away from the support connection mechanism is conical.
[0009] As a further scheme of the present invention: A first anti-corrosion coating is uniformly smeared on the outer wall of the support connection mechanism. A second anti-corrosion coating is uniformly smeared on the outer wall of the limiting rod. The materials of the first anti-corrosion coating and the second anti-corrosion coating are anti-corrosion paint.
[0010] As a further scheme of the present invention: Installation plates are fixedly connected to both ends of the buffer spring. Installation bolts are arranged on the installation plates. The installation plates are screwed and fixed to the limiting rod through the installation bolts.
[0011] As a further scheme of the present invention: The distance between each group of blocking plates is ten centimeters. The material of the blocking plates is iron plate with a thickness of five millimeters. The material of the anti-collision buffer layer is anti-collision foam.
[0012] As a further scheme of the present invention: A number of uniformly distributed support brackets are fixedly connected to the bottom of the buffer mechanism. A support plate is fixedly connected to one end of the support bracket far away from the buffer mechanism. Fixing holes are formed in the support plate.
[0013] As a further scheme of the present invention: High-strength bolts are arranged on the high-strength fixing plate. The high-strength fixing plate is screwed and fixed to the buffer mechanism through the high-strength bolts.
[0014] As a further aspect of the present invention, a steam supply system for an electrode-type humidifier is provided, the usage steps of which are as follows:
[0015] A: When using it, first place the support connection mechanism of appropriate height on both sides of the road where the height restriction is required. Insert the fixing rod on the support connection mechanism into the ground. Then, drive the external expansion bolts through the connecting holes on the connection plate into the ground. Install the two limiting rods on the top of the support connection mechanism. Slide the first slider at the bottom of the two limiting rods into the first slide groove. Adjust the distance between the two limiting rods. Install the buffer spring between the two limiting rods. Then, install the buffer mechanism on the side of the support connection mechanism, align the second slide groove with the first slide groove, and drive the external expansion bolts through the fixing holes into the ground to fix the support bracket. Place several sets of blocking plates into the second slide groove, distribute the distance between each set of blocking plates, and then spot weld each set of blocking plates to achieve the connection between the blocking plates and the buffer mechanism. Then, insert the transverse blocking rod through the buffer mechanism into the locking positioning plate. Finally, close the opening end of the buffer mechanism and connect the high-strength fixing plate to the buffer mechanism.
[0016] B: After completing step A, when a truck or bus exceeding the height limit bar passes by, it will collide with the limit bar. The first limit bar that comes into contact with the oversized vehicle will move towards another limit bar under the impact force. The buffer spring between the two limit bars will be compressed, thus playing a certain buffering role. Then, the first slider at the bottom of the two limit bars will enter the second slide through the first slide groove. If the oversized vehicle continues to move forward, the first slider will hit the blocking plate, thus generating resistance to stop the oversized vehicle from moving forward. If the oversized vehicle breaks through all the blocking plates and the transverse blocking bars, it will encounter a high-strength fixed plate to forcibly stop it. At this time, the speed of the oversized vehicle will be reduced to a certain extent, and the anti-collision buffer layer between each set of blocking plates will also play a buffering role, thereby reducing the impact force on the oversized vehicle. By using several sets of blocking plates to stop the oversized vehicle from moving forward, if a collision occurs with this device in the case of driver fatigue or low visibility, the kinetic energy of the oversized vehicle can be reduced in batches, preventing a violent collision. This gives the driver time to react and apply the brakes in time, reducing the damage to the oversized vehicle and ensuring the driver's personal safety.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] 1. In the event of a collision between a driver who is fatigued or in low visibility conditions and the vehicle, the buffer mechanism will use several sets of baffles and lateral baffles to stop the oversized vehicle from moving forward. This will reduce the kinetic energy of the oversized vehicle in batches, preventing a violent collision and giving the driver time to react and apply the brakes in time, thus reducing the damage to the oversized vehicle and ensuring the driver's safety.
