Description

Technical Field

[0001] The utility model relates to the technical field of warning devices, in particular to an anti-collision type warning device for bridges. Background Art

[0002] Warning devices are conventional emergency equipment, passive reflectors made of plastic reflective materials. The principle is that when a car owner encounters a sudden traffic accident on the road, the reflective performance of the warning device is used to remind other vehicles to avoid it to avoid a secondary accident. It is widely used in bridges and roads, but the existing warning devices for bridges have some shortcomings, such as:

[0003] Announcement No.: CN207862797U is a bridge warning device. Through this combined installation, the device can effectively solve the problem that the current warning devices are relatively large in size, which brings great inconvenience to installation and transportation, saves manpower, and improves the work efficiency during installation. However, in actual use, since the device is difficult to effectively resist when it is hit, it may cause the device to have poor protection during actual use;

[0004] Therefore, we propose a collision-proof bridge warning device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-collision bridge warning device to solve the problem that most warning devices on the market currently have difficulty in effectively resisting impact when impacted, which may lead to poor protection of the device during actual use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-collision bridge warning device, comprising a device body, a first torsion spring shaft connected to the bottom of the device body, the first torsion spring shaft is located on the left side of the device body, and a support column is connected to the top of the first torsion spring shaft, and a warning sign body connected to the top of the support column, a first support plate is connected to the right side of the support column, and a sliding groove is provided inside the first support plate;

[0007] A second torsion spring shaft is connected to the top of the device body, and a pneumatic push rod is connected to the top of the second torsion spring shaft, and a connecting shaft is connected to the top of the pneumatic push rod, a sliding shaft is connected to the left side of the connecting shaft, and the sliding shaft forms a sliding connection with the sliding groove arranged inside the first support plate, and the sliding shaft is located on the middle bottom side of the sliding groove.

[0008] When the device is hit, the first torsion spring shaft will drive the support column and the warning sign body to rotate backward, and the sliding shaft inside the first support plate will also slide accordingly, causing the pneumatic push rod to retract, and then the pneumatic push rod will rotate forward driven by the second torsion spring shaft, causing the pneumatic push rod to drive the sliding shaft to move to the bottom of the sliding groove, so that the support column and the warning sign body are completely in a horizontal state. When the top pressure disappears, the first torsion spring shaft will drive the support column and the warning sign body to rotate, and the sliding shaft will also drive the pneumatic push rod to rise. At this time, the second torsion spring shaft will also drive the bottom of the pneumatic push rod to rotate, so that the warning sign body stands again, completing the operation of avoiding the impact, thereby achieving the purpose of anti-collision.

[0009] As a preferred technical solution of the utility model, a first sprocket is provided at the bottom of the warning sign body, and a second bevel gear is connected to the top of the first sprocket, and the first bevel gear is meshed on the right side of the second bevel gear, a chain is meshed on the outside of the first sprocket, and a second sprocket is meshed on the left side of the chain, and a group of threaded rods are provided at the bottom of the first sprocket and the second sprocket, and the threaded rods are threadedly connected to the inside of the support column.

[0010] The above technical solution can be used to set a sprocket mechanism and a threaded rod at the bottom of the warning sign body, and the bottom of the threaded rod is threadedly connected to the support column, so that the user can be more stable when adjusting the height of the warning sign body, thereby increasing the adjustability of the device.

[0011] As a preferred technical solution of the utility model, a group of rotating rods are connected to the right side of the first bevel gear, and the rotating rods pass through the warning sign body.

[0012] The adoption of the above technical solution enables the user to adjust the threaded rod by twisting the rotating rod, thereby increasing the operability of the device.

[0013] As a preferred technical solution of the utility model, the front part of the support column is connected to the second support plate, the front part of the second support plate is connected to the support spring shaft, and the front part of the support spring shaft is connected to the buffer pad.

[0014] The above technical solution can ensure that the impact object will not touch the warning sign body first, but will touch the buffer pad first, so that the device can use the pressure of the buffer pad to make the warning sign body and the support column fall backwards, thereby increasing the protectiveness of the device.

[0015] As a preferred technical solution of the utility model, the bottoms of the first torsion spring shaft and the second torsion spring shaft are rotatably connected to the device body, and a guard arm is connected to the top of the device body.

[0016] The adoption of the above technical solution enables the support column and the warning sign body to be protected on both sides of the warning sign body by the guard arms when the support column and the warning sign body are tipped over, thereby increasing the protection of the device when it is hit.

[0021] By arranging a sprocket mechanism and a threaded rod at the bottom of the warning sign body, and the bottom of the threaded rod is threadedly connected to the support column, the user can adjust the height of the warning sign body more stably, thereby increasing the adjustability of the device;

[0022] By setting the buffer pad, the impact object will not touch the warning sign body first, but will touch the buffer pad first, so that the device can use the pressure of the buffer pad to make the warning sign body and the support column fall backwards, thereby increasing the protection of the device;

[0023] Furthermore, by providing the guard arms, when the support column and the warning sign body fall over, the guard arms can protect both sides of the warning sign body, thereby increasing the protection of the device when it is hit. BRIEF DESCRIPTION OF THE DRAWINGS
