In order to improve and enhance the guard guarantee capability and level of the expressway accident handling rescue vehicle on the rescue site, a special guard vehicle with comprehensive functions of high identification, anti-collision capability, remote early warning, speed and distance measurement, sound and light warning, subtitle reminding, road indication, broadcast communication, blocking interception, slow speed isolation, safety protection, fire rescue and the like is particularly needed. But is still vacant in the markets both abroad and domestically.
The Chinese patent with the application number of 201110385355.3 and the name of 'automatic traffic cone folding and unfolding equipment' discloses a cone placing device, a hanging device and a guiding device which are arranged at two ends of the cone placing device, and a supporting device arranged at the bottom of the cone placing device. The device can only realize the stable release of the traffic cone, but cannot automatically recover the traffic cone, has single function, and cannot remarkably save manpower and improve efficiency.
The Chinese patent with the patent application number of 201010105992.6 and the invention name of 'automatic traffic cone folding and unfolding equipment' comprises a hanging device and a folding and unfolding device, wherein the hanging device controls the lifting and unfolding movement of the folding and unfolding device, the folding and unfolding device realizes the unfolding of the traffic cone through a chute and a directional device, and a motor drives a chain and a rolling pull rod to realize the folding and unfolding of the traffic cone. Although the device can realize the releasing and recovering functions of the traffic cone, the whole process also needs manual matching operation, for example, in the releasing process of the traffic cone, the traffic cone needs to be manually swung on the chute; in the recovery process of the traffic cone, the traffic cone recovered into the carriage needs to be manually placed. Therefore, the automatic traffic cone collecting and releasing device is a semi-automatic device in essence, and cannot completely realize the automatic operation without manpower, so that the aim of saving manpower cannot be fundamentally realized.

Although the special vehicle can realize the releasing and recovering functions of the traffic cone, the releasing and recovering functions in the releasing and recovering process of the traffic cone are low in efficiency and low in success rate, so that the traffic cone is very easy to fall down and is difficult to accurately enter the releasing and recovering device. Therefore, the special vehicle for the fully-automatic retraction and storage of the traffic cones has many defects and shortcomings in design structure, and needs to be further improved and enhanced.
In order to solve the technical problems, the inventor of the invention invents the automatic traffic cone retracting and releasing vehicle, but the applicability of the automatic retracting and releasing vehicle is limited to special vehicles, and the automatic traffic cone retracting and releasing device greatly limits the flexibility of the vehicles and is not beneficial to executing other alert rescue tasks. At present, a corresponding traffic cone retracting device for an alert rescue fire truck does not exist, and a retracting device which is practical for the alert rescue fire truck is urgently needed to be developed.
