Description

Self-locking anti-climbing roller

Technical Field

The utility model relates to an automobile inspection equipment field especially relates to from locking-type anti-creep roller.

Background

Vehicle testing is the examination of a vehicle to determine the technical state or operational capability of the vehicle. When the automobile is used, parts of the automobile are gradually worn, corroded, deformed and aged along with the prolonging of the service time (or the increase of the driving mileage), the deterioration of lubricating oil and the like, so that the clearance of a matching pair is enlarged, loose movement, vibration, noise, air leakage, water leakage, oil leakage and the like are caused, and the technical performance of the automobile is reduced. The core of automobile maintenance (or called automobile maintenance) is to "maintain" the technical state of the automobile. The brake performance of the automobile is detected on an automobile brake performance inspection table due to the requirement of safe driving, and the double-shaft automobile is efficiently and quickly widely applied by adopting the double-shaft brake inspection table. However, when the double-shaft brake is carried out, the acting force of the front and rear inspection platform rollers on the wheels generates backward thrust on the automobile, and in order to prevent the automobile from climbing backwards, the brake inspection platform is provided with an anti-climbing roller behind the rear roller of the brake platform.

When the anti-climbing roll does not work, the anti-climbing roll falls to the same horizontal height of the roller of the brake table through the air cylinder, so that the automobile is enabled to go up to the brake inspection table, the anti-climbing roll is lifted to the high ground of a working position after the automobile is in place, the automobile is prevented from moving backwards to get out of the brake inspection table, the component force of pushing the automobile backwards by the large roller of the corresponding brake force is large, the wheel pressure with large axle load exceeds the pushing force of the air cylinder on the anti-climbing roll, the anti-climbing roll is pressed downwards to cause anti-climbing failure, the automobile gets out of the brake inspection table backwards, the size of the air cylinder cannot be increased infinitely due to the limitation of structural space arrangement conditions, and the phenomenon that the.
