Abstract

The invention belongs to the field of friction force measuring devices, and particularly relates to an automatic data acquisition experimental device for bridge expansion joint travel resistance. Theautomatic data acquisition experimental device comprises a rubber belt placing device, a profile steel fixing platform, a driving device and a dynamometer; the driving device drives the rubber belt totravel in the profile steel on the profile steel fixing platform; the dynamometer measures the frictional force acted on the rubber belt during travelling; the driving device includes a servo motor,a main sprocket wheel, a chain, and steering sprocket wheels; the servo motor is connected to the main sprocket wheel, the chain is connected to the main sprocket wheel and the steering sprocket wheels, and then a closed-loop control is formed; the rubber belt moves synchronously with the chain through a fixing device; a fixing frame for mounting the dynamometer is fixed at one end of the profilesteel fixing platform, and is opposite to the rubber belt placing device; a moving box is installed in the fixing frame, and the corresponding steering sprocket wheel is fixed in the moving box; the dynamometer is in contact with the moving box; and the dynamometer is connected to the computer for data acquisition. The automatic data acquisition experimental device is stable in operation, is highin transmission efficiency, is high in measurement accuracy, is high in automatic level, and is simple to operate.

Description

technical field [0001] The invention belongs to the field of friction measuring devices, and in particular relates to an automatic data collection experiment device for the running resistance of bridge expansion joints. Background technique [0002] According to the railway industry standard of the People's Republic of China: when the waterproof device at the beam end adopts the replacement method of pulling out the waterproof rubber belt and the locking strip, the waterproof rubber belt or the locking strip is penetrated from one end of the cavity or groove of the special-shaped profile until it is inserted from the other end. One end goes out, and the passing resistance in the cavity should not be greater than 3KN. Therefore, the running performance of the rubber belt has strict requirements, and more accurate performance data are often obtained through the inspection of the experimental platform. The currently used experimental device uses a stepping motor as the driving...
