Highway barrier automatic retracting and releasing device

Abstract

The invention relates to the field of highway barrier design, in particular to a highway barrier automatic retracting and releasing device. The highway barrier automatic retracting and releasing device comprises a box body, and guide rails are fixedly arranged on the inner sides of the left and right ends of the box body. A driving rod is arranged at the top end of a driving device, a sliding block is fixedly connected to the top end of the driving rod, and the sliding block is connected with the guide rails in a sliding-fit mode. A plurality of barricade rods are fixedly arranged at the top of the sliding block, a bracket is fixedly arranged on one side of the box body, and a sound production device and a warning lamp shade are arranged at the top end of the bracket from bottom to top insequence. Under work of the driving device, the barricade rods move up and down to warn and block vehicles running on the roadside and crowds and effectively prevent the vehicles from forcibly crossing a barricade, a fluorescent warning panel and an LED warning lamp can play the role of visual signal warning at the same time, in addition, the sound production device can play the role of auditory signal warning, and through the restrictions on the passing vehicles and the crowds, the traffic order is effectively ensured. The highway barrier automatic retracting and releasing device realizes theautomatic expansion and contraction of the barricade rods, occupies less space, and is durable and high in practicability.

Description

technical field [0001] The invention relates to the field of road obstacle design, in particular to an automatic retractable device for road obstacles. Background technique [0002] In order to maintain traffic order, many places will set up barriers and roadblocks. The main function is to make driving safer for everyone. Present barricades all are made of plastic usually, have certain hardness, and some barricades are made pyramidal or conical. Widely used in road accidents, construction, traffic diversion, etc. For the convenience of carrying, roadblocks are generally made of plastic, so that they are easy to be blown down by the wind when they are placed. If they are not remedied in time, accidents are prone to occur. Moreover, the existing roadblock facilities do not have the function of automatic shrinkage, which has a single function and takes up a lot of space. space. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present inv...
