Description
Technical Field
[0001] The utility model belongs to the technical field of safety devices, and in particular relates to a safety innovation device for a motor vehicle exhaust environmental protection evaluation dynamometer. Background Art
[0002] Common methods for automobile exhaust detection include simple transient method and loaded deceleration method. According to the standard requirements of GB18285-2018 "Gasoline Vehicle Pollutant Emission Limits and Measurement Methods (Dual Idle Method and Simple Working Condition Method)", the maximum speed of the vehicle can reach 50km / h when using the simple transient method for detection; according to the standard requirements of GB3847-2018 "Diesel Vehicle Pollutant Emission Limits and Measurement Methods (Free Acceleration Method and Loaded Deceleration Method)", the maximum speed of the vehicle when using the loaded deceleration method for detection is close to 70km / h. At this time, the vehicle tires will generate a very high linear speed. Although the debris on the tires will be checked and removed before entering the test, it is impossible to completely remove it in reality. Therefore, if there are stones and other debris mixed in the tires that have not been removed and fly out, it may cause serious harm and damage to surrounding staff, instruments and facilities, other vehicles to be inspected, etc., thereby causing unnecessary personal injury and economic losses. For this reason, we propose a safety innovation device for motor vehicle exhaust environmental evaluation dynamometer. Utility Model Content

[0029] The universal wheel 2 adopts a universal wheel with a brake, which is convenient for fixing on the ground without affecting the convenience of movement.
[0030] There are three reinforcing ribs 6 in total, and the three groups of reinforcing ribs 6 are respectively arranged at the upper, lower and middle positions of the back side of the safety baffle 3 .
[0031] Three groups of reinforcing ribs 6 are respectively arranged at the upper, lower and middle positions of the back side of the safety baffle 3 to uniformly reinforce the structure of the safety baffle 3 .
[0032] There are two triangular reinforcement brackets 7, which are respectively located behind the junction between the transverse section baffle 4 and the inward-inclined section baffles 5 on both sides.
[0033] There are two triangular reinforcing brackets 7 , which are respectively located behind the junction between the transverse baffle 4 and the inwardly inclined baffles 5 on both sides, and can evenly support the safety baffle 3 .
[0034] The silicone buffer layer 9 and the embedding groove 8 are connected by rivets.
[0035] The silicone buffer layer 9 and the embedding groove 8 are connected by rivets, so the installation stability is strong and it can avoid falling off.
[0036] The working principle and use process of the utility model: when the device is used, the universal wheel 2 is used to move the device to the rear of the car to be tested, and the brake device on the universal wheel 2 is used to brake the universal wheel 2 so that the device will not move. After the test starts, large particles such as stones thrown out by the rapid rotation of the car wheel can be blocked by the safety baffle 3 to prevent the stones from being thrown out too far. At the same time, due to the provision of the foam energy-absorbing layer 10 and the silicone buffer layer 9, the kinetic energy of the flying stones can be well buffered. In particular, the foam energy-absorbing layer 10 is provided, and its porous structure can be utilized. In addition to effectively buffering the impact force of the stones, it can also prevent the stones from rebounding and make the stones embedded therein as much as possible, thereby avoiding damage to the vehicle caused by the stones due to rebound. The safety baffle 3 includes two sections: a transverse baffle 4 and an inwardly inclined baffle 5. By setting the inwardly inclined inwardly inclined baffle 5, it is further The situation in which stones are ejected to the left and right sides of the device is avoided. The structural strength of the safety baffle 3 is greatly enhanced by the arrangement of the reinforcing ribs 6 and the triangular reinforcing bracket 7, which plays a good reinforcing and supporting role. The particles falling out of the foam energy absorbing layer 10 can also be collected through the collecting groove 14. When the foam energy absorbing layer 10 needs to be replaced, the limit bolt 12 is unscrewed using the finger ring 13, and the foam energy absorbing layer 10 can be taken out and replaced. In summary, the device can block the splashing particles generated during the test and effectively buffer their impact force through the arrangement of the safety baffle 3, the silicone buffer layer 9, and the foam energy absorbing layer 10, and can also prevent these particles from rebounding, effectively protecting the test personnel, the doors and windows of the test site, and the equipment. At the same time, it can block the particles discharged from the exhaust pipe of the diesel vehicle to prevent them from directly pouring into the workshop, thereby avoiding the pollution impact on the subsequent inspection vehicles and inspectors.
