Description

An adjustable height-limiting frame with high warning

Technical Field

The utility model relates to the technical field of height limit frames, in particular to an adjustable height limit frame with high warning performance.

Background technique

There are two types of height limit frames: fixed height limit frames and adjustable height limit frames; fixed height limit frames are further divided into fixed integrated height limit frames and fixed indestructible height limit frames. Fixed integrated height limit frames are one-time non-adjustable height limit frames that rely on the frame itself to intercept vehicles. Fixed indestructible height limit frames must be lifted by external forces, such as cranes, to allow vehicles to pass in an emergency; fixed integrated height limit frames are mainly used for gate-type frames at the entrances of bridges, culverts, and tunnels. They are generally welded steel structures and play a role in protecting bridges, culverts, and tunnels; there are signboards with the height limit in meters to remind vehicles. Adjustable height limit frames are divided into manual height limit frames and electric height limit frames; manual height limit frames can manually lift the height limit pole when needed through a manual device; electric height limit frames are divided into electric height limit frames, electric hydraulic height limit frames, pneumatic height limit frames, etc.

After searching, the existing patent (publication number: CN216586274U) discloses a height limit frame, including embedded parts, support rods are fixed on the embedded parts, two support rods are installed with two-color lighting lamps on the top, a fixed beam is connected between the two support rods, a horizontal groove is formed at the bottom of the fixed beam, and a limited height pole is connected in the horizontal groove through an adjustment mechanism, and the limited height mark is connected to the bottom of the height limit pole on both sides, and a distance sensor and a camera are embedded in the middle of the height limit pole. The two support rods are respectively concavely formed with vertical grooves on the opposite sides, and a driving cavity and a control cavity are also provided in one of the support rods. A driving motor connected to the adjustment mechanism is installed in the driving cavity, and a controller, a memory and a battery for power supply are installed in the control cavity. The controller is electrically connected to the memory, the driving motor, the lighting lamp, the distance sensor and the camera. The utility model can detect the height of the vehicle and the lighting lamp will light up and alarm when the vehicle is overheight, and when a special vehicle needs to pass, the height limit pole is raised by the controller to facilitate passing. The inventors found the following problems in the prior art during the implementation of the utility model: the traditional height limit frame is prone to dust clogging when not used for a long time during the adjustment process, which makes it easy to get stuck during the adjustment process, and the lubrication effect is poor. At the same time, the height adjustment range is short and cannot better adapt to various adjustment situations;

Therefore, in view of the above problems, an adjustable height limit frame with high warning is proposed.
