Abstract

The invention discloses a loading device used in a road seam filling material low-temperature performance test, and relates to a material low-temperature performance test loading device. With an existing loading device, test sample assembly speed is low, and loading is carried out with a slide way manner such that certain resistance is caused and test precision is influenced. The invention aims at solving the problems. The device provided by the invention comprises an oil tank, a bearing plate, a transmission unit, a supporting sliding unit, and a loading unit. The transmission unit comprises a motor, a speed reducer, a first bevel gear, a second bevel gear, a transmission shaft, a fixed rack, and a transmission part. The supporting sliding unit comprises a slide rail, a slide plate, a connection assembly, and a transition plate. The loading unit comprises a pressure sensor, a mobile loading platform, a fixed loading platform, and two sets of fixtures. The fixed rack is arranged on the bearing plate arranged on the bottom end face of the oil tank. The slide plate is arranged on the slide rail and can slide on the slide rail. The output end of the motor and the input end of the speed reduced are connected. The first bevel gear is engaged with the second bevel gear. The device provided by the invention is used in the road seam filling material low-temperature performance test.

Description

technical field [0001] The invention relates to a loading device for a low-temperature performance test of materials, in particular to a loading device for testing the low-temperature performance of road joint filling materials, and belongs to the technical field of road surface maintenance. Background technique [0002] At present, there are various types of joint filling materials on the market, and the quality is uneven, which often cannot achieve the expected maintenance effect. Some joint filling materials fail in the first winter after use. Repeated joint filling work has brought huge maintenance workload and economic loss. Therefore, it is very important to develop a set of equipment for evaluating the low-temperature performance of the joint filling material and the adhesion performance of the joint filling material and the joint wall. Previously, through literature search, the Chinese patent No. 200910072201.1 proposed a low-temperature performance tester for road ...
