A kind of steel bridge asphalt pavement shear fatigue testing equipment

Abstract

The invention discloses a steel bridge asphalt pavement shear fatigue testing equipment, which comprises a device casing, a clamping plate, a heat dissipation frame, a roller and a support rod. A worm is rotatably connected in the device casing, and the heat dissipation frame is welded and fixed. There is a first drive motor, and the output end of the first drive motor is engaged with a transmission belt, and the output end shaft of the first drive motor is connected with a cooling fan, the heat dissipation frame is screwed with a storage box, and the upper flange of the storage box is A small water pump is connected, and a cooling pipe is bolted to the small water pump. The steel bridge asphalt pavement shear fatigue testing equipment is provided with a heat dissipation frame. Under the action of a small water pump, the cooling liquid in the storage box can be transported to the cooling pipe, and the air around the cooling fan can be quickly cooled down. The asphalt sample is effectively cooled and formed, which effectively improves the use efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of steel bridge pavement detection, in particular to a shear fatigue degree detection device of a steel bridge asphalt pavement. Background technique [0002] A steel bridge is a bridge made of steel for its bridge-span structure. In the process of using steel bridges, asphalt concrete is generally used to lay on the steel bridge deck. The stress and deformation caused by the load, etc., can protect the steel plate and provide good driving performance. The service performance and service life of the bridge are closely related to the quality of the bridge deck. When the car drives on the asphalt road on the steel bridge for a long time, it will Shear force is generated on the asphalt pavement, which will lead to cracking and damage of the asphalt pavement. Therefore, in order to ensure the stability of the asphalt pavement, it is necessary to use a testing device to detect the shear fatigue of the asphalt pav...
