[0028] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] An embodiment of the utility model provides a road operation warning area engineering vehicle.

[0030] Example 1: Figure 1-10As shown, a road operation warning area engineering vehicle includes an engineering vehicle 20, and the engineering vehicle 20 is provided with a retracting device and a cone barrel device 9, and the retracting device is provided with a platform frame 5, and a roller 1 is provided on the platform frame 5, and a rotating shaft 2 is provided in the middle of the roller 1, and four side shafts are provided on the side of the roller 1, and the two ends of the rotating shaft 2 are arranged on the fixed block on the platform frame 5. An airflow adapter 3 is provided on one end of the rotating shaft 2, and the airflow adapter 3 can be externally connected to an air compressor. The external air compressor can detect the air pressure inside the hose 4 during use. When the air pressure inside the hose reaches the set value, the air compressor stops working; a retracting motor 6 is provided on the rotating shaft 2 at the other end, and the retracting motor controls the rotation of the roller 1. The rotating shaft 2 near one end of the airflow adapter 3 is provided with a groove, and a hose 4 extends from the groove. The top of the hose 4 is arranged on the airflow adapter 3, and the hose 4 is wound on the roller 1. The hose 4 is made of wear-resistant material, so the weight of the hose 4 is also heavy, which reduces the influence of external force when the warning area is preset. A small hole is arranged every five meters on the hollow surface of the hose 4. A pneumatic whistle 8 is arranged in the small hole of the hose 4. The pneumatic whistle 8 will make a sound when there is air circulation in the hose 4. The bottom of the pneumatic whistle 8 is arranged in the hose 4. The air outlet is wrapped with a stretch belt 7. The stretch belt 7 is hollow inside and made of plastic material outside. The stretch belt 7 is flexible and is rolled up on the drum 1 together with the hose 4 during normal storage. When there is air circulation in the hose 4, the air blows from the pneumatic whistle 8 to the inside of the stretch belt 7. The air inside the stretch belt 7 increases, so that the stretch belt 7 begins to grow and take shape. The stretch belt 7 is made of PVC plastic material, and a reflective material coating is arranged on the surface of the stretch belt 7. The pneumatic whistle 8 will make a sound when the hose 4 is inflated and deflated. The hose 4 will not make a sound when it is full of air. When an emergency occurs or a vehicle crashes into the stretch belt 7, the air flows out of the hose 4 quickly. The pneumatic whistle 8 makes a harsh sound to warn the operator in the case of pressure difference. A cone barrel device 9 is provided at the end of the hose 4. The bottom of the cone barrel device 9 is a semi-spherical weight block. The cone barrel device 9 is overall heavy at the bottom and light at the top, so that the cone barrel device 9 can be automatically corrected to prevent it from falling due to external force when placed. A battery is provided inside the cone barrel device 9. A sound and light generator 11 is provided on the top of the cone barrel device 9, which can emit sound and warning lights to remind passing vehicles. The semi-spherical weight block at the bottom of the cone barrel device 9 can be removed from the cone barrel device 9. The semi-spherical weight block is snap-connected with the cone barrel device 9. A knob 10 is provided on the cone barrel device 9. The battery can be installed inside by unscrewing the knob 10. A reflective material coating is provided on the surface of the cone barrel device 9. The cone barrel device 9 is also provided with another one, and a thicker canvas is connected between the two cone barrel devices 9. A sign prohibiting passage and changing lanes to the right is painted on one side of the canvas, and a sign prohibiting passage and changing lanes to the left is painted on the other side. Both signs are painted with reflective materials, and which side to use can be adjusted at any time according to on-site needs.A canvas mounting hole is provided on the top of the cone barrel device 9 , and a plug-in shaft is provided on the canvas. The plug-in shaft is installed in the canvas mounting hole to realize setting the canvas on the two cone barrel devices 9 .

[0031] Working principle: The retractable device and the cone barrel device 9 are placed on the engineering vehicle 20. When the engineering vehicle 20 drives to the designated place, the worker first takes down the cone barrel device 9 from the engineering vehicle 20 and places the cone barrel device 9 in the middle of the road in the warning area. Another cone barrel device is set on one side of the road. Fig. 9 The canvas is placed between the two cone barrel devices 9 according to actual needs. The protective shell on the airflow adapter 3 on the retractable device is removed, and the airflow adapter 3 is connected to the air compressor. The sound and light generator 11 on the cone barrel device 9 is started, and the sound and light generator 11 starts to work and emits sound and starts to flash. The air compressor is started to turn on the retractable motor 6, and the drum 1 on the retractable device starts to rotate, and the hose 4 on the drum 1 starts to be released. The worker drives the engineering vehicle 20 to move forward. The worker driver adjusts the speed of the engineering vehicle to the speed of the hose 4 released by the drum 1. At this time, the air in the middle of the hose 4 released from the drum 1 is blown out from the pneumatic whistle 8 on the surface of the hose 4 and a warning sound is issued. The stretch belt 7 on the pneumatic whistle 8 starts to inflate and wave, and the engineering vehicle 20 stops at the place. The staff turns off the retractable motor 6, and the hose 4 stops being released. The warning area is set up, and the staff starts construction. Because reflective materials are provided on the surface of the cone barrel device 9 and the stretch belt 7, in some special cases, such as foggy days, nights, rainy days and other low visibility conditions, a signal can be given to the driver in advance to slow down, and at the same time, the reflection of the sound and light generator 11 and the stretch belt 7 on the hose 4 can also remind passing vehicles to slow down, ensuring the driving safety of passing vehicles and the construction safety of road maintenance workers. The engineering vehicle 20 can usually adopt a light truck chassis.

[0032] When the road maintenance staff finishes the road work, they start to deflate the hose 4 through the airflow adapter 3. After the hose 4 is deflated, the staff turns on the retracting motor 6 to start recovering the hose 4, and the drum 1 starts to rotate to recover the hose 4. After the cone barrel device 9 is recovered to the rear of the engineering vehicle 20, the staff moves the cone barrel device 9 onto the engineering vehicle 20 to complete the removal of the warning area. The semicircular design of the bottom of the cone barrel device 9 is also very convenient when recovering the cone barrel device 9, because the contact area between the cone barrel device 9 and the ground is small, and there will be no damage to the entire device when it is recovered and pushed.

[0033] The sound and light generator 11 and the stretch belt 7 on the cone barrel device 9 are provided with reflective materials, so that in some conditions of low visibility, the drivers of passing vehicles can be warned by both sound and light. These settings improve the safety of road operations and protect the safety of passing vehicles and construction workers.

[0034] Embodiment 2: The material of the stretch belt 7 can also be rubber material, and other features are consistent with those of Embodiment 1.
