Abstract

The invention provides a friction coefficient detection device for pallet beams. The detection device comprises a steel frame, wherein the fixed end of the steel frame is connected with the ground in a hinging manner, and the free end of the steel frame is connected with a distance measurement component arranged on the ground; a displacement limiting component and a displacement measurement component are arranged on the upper surface of the steel frame; the displacement limiting component is arranged on the side close to the fixed end of the steel frame, and the displacement measurement component is arranged on the side close to the free end of the steel frame; beam clamping fixtures are arranged between the displacement limiting component and the displacement measurement component; the beams are arranged on the beam clamping fixtures; the distance between the beams can be freely regulated by virtue of the beam clamping fixtures; a carrying pallet is arranged on the beams; the free end of the steel frame is hoisted through hoisting equipment. According to the detection device, friction coefficients between different material pallets and different coating beam combinations can be tested along a roadway and in a direction perpendicular to the roadway, the detection device is easy to operate, and can be used for estimating static and dynamic friction factors of a goods shelf to provide a basis for the anti-seismic design of the goods shelf, and data can be conveniently and rapidly processed.

Description

technical field [0001] The invention relates to a device for measuring the sliding friction coefficient between a shelf pallet and a crossbeam in the direction of the roadway and the direction perpendicular to the roadway, and a measurement method for detecting the friction coefficient of the pallet, belonging to the technical field of mechanical engineering. Background technique [0002] With the rapid development of logistics and warehousing industry, safety issues in the design and use of large shelves have attracted increasing attention. During the seismic design of pallet racks, the response of the system structure to seismic shock needs to be revised through the seismic impact coefficient of the rack structure, among which the friction coefficient reflecting the energy loss caused by the friction of pallet beams is an important revision index. [0003] Affected by the nature of the pallet material, the type of beam coating and the shelf specifications, the energy loss ...
