Description

Technical Field

[0001] The utility model belongs to the technical field of road maintenance equipment, and in particular relates to an emergency road sealing vehicle. Background Art

[0002] At present, during maintenance work on highways in my country, the placement and recovery of traffic cones are carried out by 2 to 3 construction workers at the rear of a road engineering vehicle along a specific route on the highway. This manual operation method has a slow operation speed, a low safety factor, and the spacing of traffic cones is not uniform. The above problems are particularly prominent when working on urban expressways with heavy traffic volume. At the same time, it is easily affected by weather and environmental factors, and the risk factor is even higher in severe environments such as heavy fog, heavy rain or thunderstorms.

[0003] In recent years, although some units have begun to focus on the research of automatic traffic cone retracting and deploying devices, the technology is not yet mature and the cost cannot be reduced. In addition, there has not yet been any equipment that can automatically store a large number of traffic cones to meet the demand for placing a large number of traffic cones at one time on highways and urban expressways; there has also been no equipment that can adapt to the complex traffic conditions in the country and can place traffic cones at any position and interval on the road.

[0004] The Chinese patent application number is 201110385355.3, and the invention name is "Automatic Retracting and Retracting Equipment for Traffic Cones", which discloses a device including a cone placing device, a suspension device and a guide device arranged at both ends of the cone placing device, and a support device arranged at the bottom of the cone placing device. This device can only realize the stable placement of traffic cones, but cannot automatically retract traffic cones. It has a single function and cannot significantly save manpower and improve efficiency.

[0005] The Chinese patent with application number 201010105992.6 and invention name "Automatic Retracting and Unloading Device for Traffic Cones" includes a suspension device and a retracting and unloading device. The suspension device controls the lifting and lowering movement of the retracting and unloading device. The retracting and unloading device realizes the application of traffic cones through a chute and a directional device, and realizes the recovery of traffic cones through a motor-driven chain and a rolling pull rod. Although the device can realize the application and recovery functions of traffic cones, the whole process still requires manual cooperation. For example, during the application of traffic cones, it is necessary to manually place the traffic cones on the chute; during the recovery of traffic cones, it is necessary to manually place the traffic cones retracted into the car. It can be seen that this automatic retracting and unloading device for traffic cones is essentially a semi-automatic device, which cannot completely realize automatic operation without manual operation. Therefore, it cannot fundamentally achieve the purpose of saving manpower.

[0006] The Chinese patent with the patent application number of 201310403155.5 and the invention name of "Special Vehicle for Fully Automatic Retracting and Storage of Traffic Cones" includes a retracting device for retracting and releasing traffic cones arranged at the rear end of the vehicle chassis, the retracting device is connected to a moving device for controlling its movement; a traffic cone entry device is also arranged on the vehicle chassis, and a conveying device is arranged between the entry device and the retracting device; the entry device is connected to a storage device with a multi-layer structure arranged on the vehicle chassis; the retracting device, the moving device, the conveying device, the entry device, and the storage device are respectively connected to an intelligent control system and a power supply and distribution system. Although the special vehicle can realize the functions of placing and retrieving traffic cones, the retracting function is inefficient and the success rate is not high during the process of realizing the retracting and releasing of traffic cones, which makes it very easy for traffic cones to fall and difficult to accurately enter the retracting and releasing device. It can be seen that this special vehicle for fully automatic retracting and storing traffic cones still has many defects and shortcomings in the design structure, which needs to be further improved and improved.
