Shallow-buried roadblock capable of ascending and descending quickly

Abstract

The invention discloses a shallow-buried roadblock capable of ascending and descending quickly, and relates to the technical field of shallow-buried roadblock equipment. The shallow-buried roadblock capable of ascending and descending quickly comprises a plurality of lifting columns, intelligent positioning recognition mechanisms, radar position recognition mechanisms and a hydraulic control unit, the number of the intelligent positioning recognition mechanisms and the number of the radar position recognition mechanisms are in one-to-one correspondence with the number of the lifting columns, The intelligent positioning recognition mechanisms are used for automatically recognizing vehicle information and vehicle position information. The shallow-buried roadblock is reasonable in structure, information identification of a vehicle and width identification, position identification and distance recognition of the vehicle are achieved, so that lifting of the lifting columns at different positions is intelligently controlled through the hydraulic control unit, the lifting speed of the lifting columns is increased, the lifting number of the lifting columns is controlled according to the width of the vehicle, the lifting columns do not need to be lifted at the same time, on one hand, power provided by the control pump is reduced, energy consumption is reduced, the passing requirements of vehicles of different sizes are met, and on the other hand, the service life of the lifting columns is prolonged.

Description

technical field [0001] The invention relates to the technical field of shallow-buried roadblock equipment, in particular to a fast-moving shallow-buried roadblock. Background technique [0002] As a kind of hard isolation facility, the columnar lifting barricade car arrester (hereinafter referred to as the lifting column) has the biggest advantage of strong blocking ability after being raised, and it does not occupy any surface space after being lowered. It is used in various security requirements. the entry and exit passages of the area. [0003] However, at present, almost all lifting column products have no ability to perceive and recognize direct information such as the position, speed, appearance, and access authority of vehicles entering and exiting the surrounding and environmental conditions and changes. They need external equipment to collect these information. , analysis and processing. In addition, almost all lifting columns currently have almost no perception, f...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned lifting columns can realize vehicle information recognition and automatic control of lifting, however, each time after the vehicle information is recognized, multiple lifting columns are raised or retracted at the same time, and the different sizes and widths of the vehicles cannot be recognized to control different positions. The lifting column is raised and lowered, resulting in a waste of power to control the pump, reducing the lifting speed of the lifting column, and reducing the service life of the lifting column
