Problems solved by technology

But what kind of pattern can be used to better improve the adaptability of the wheels of warehouse logistics vehicles to different road surfaces, and there are few professional equipment that can accurately detect the impact of different patterns on the wheels of warehouse logistics vehicles
[0004] When the roundness of the wheel surface of the warehouse logistics vehicle is not high enough, the bearing technology is not high enough, or other accidental factors, the wheels of the warehouse logistics vehicle may be stuck when running, and it is difficult to detect the wheels of the warehouse logistics vehicle at this time

Abstract

A warehouse logistics vehicle wheel simulation device comprises a support frame body, a pressure applying device and a simulation wheel assembly. The support frame body comprises a base, a stand column, a T-shaped mounting plate and supporting ribs, wherein the base is fixed on a test plane; the bottom of the stand column is fixedly connected with the base, a cantilever is arranged at the top ofthe stand column, and a sliding groove is formed in the cantilever in the axial direction; the tail part of the T-shaped mounting plate is inserted into the sliding groove; the pair of supporting ribsare arranged on the upper portion and the lower portion of the stand column in an up-down staggered mode; the pressure applying device is suspended at the head of the T-shaped mounting plate and comprises a lifter and a suspension, the top of the lifter is fixedly mounted at the head of the T-shaped mounting plate, and the lifting end of the bottom of the lifter is fixedly connected with the topof the suspension; the suspension comprises an upper suspension, a spring and a lower suspension; the spring is arranged between the upper suspension and the lower suspension; and the simulation wheelassembly comprises a mounting frame, a simulation wheel and a driving motor. The device has the beneficial effects that the driving wheel can be prevented from being pinned due to insufficient roundness of the wheel surface through the suspension, so that the pressure applied to the roller by the driving wheel is more balanced, and the error-tolerant rate of the system is improved.

Description

technical field [0001] The invention relates to a wheel simulation device for storage logistics vehicles. Background technique [0002] With the great development of intelligent logistics, the application of warehousing and logistics vehicles is becoming more and more extensive, and the requirements for them are also getting higher and higher. The goods need to be sent from the warehouse to the workshop often need to pass through different roads. At present, most of the warehousing and logistics vehicle wheel tires of warehousing and logistics vehicles use smooth surfaces. This form of warehousing and logistics vehicle wheels is simple to manufacture and has high economic efficiency; The surface of the wheel is prone to produce a water film between the road surfaces, resulting in skidding. [0003] The anti-skid lines on the tires increase the friction of the wheels of the warehouse logistics vehicles during the load operation process, reduce the slipping phenomenon, and ma...
