Rapid switching device of wheeled multipurpose engineering vehicle
The invention provides a rapid switching device of a wheeled multipurpose engineering vehicle. The rapid switching device comprises a bracket, an oil cylinder and a hinge pin for locking a working machine tool, wherein the oil cylinder is fixed on the bracket, and a telescopic rod of the oil cylinder is connected with the hinge pin through a connecting rod structure; and the telescopic rod telescopes to control the hinge pin to stretch out and draw back, and after the telescopic rod extends out in place, the connecting rod structure forms a connecting rod dead point for preventing the hinge pin from returning. According to the rapid switching device of the wheeled multipurpose engineering vehicle, after the oil cylinder is arranged to push the hinge pin to be inserted into a pin hole in place, the connecting rod dead point is formed, and stable supporting is formed, so that the stability and reliability of connection between the working machine tool and the bracket are ensured.
本发明提供了一种轮式多用工程车的快速切换装置，包括托架、油缸和用于锁定工作机具的销轴，油缸固定在托架上，油缸的伸缩杆通过连杆结构与销轴相连，并通过伸缩杆的伸缩控制销轴的伸缩，伸缩杆伸出到位后，连杆结构形成防止销轴回退的连杆死点。本发明提供了一种轮式多用工程车的快速切换装置，通过设置油缸推动销轴与销孔插合到位后，形成连杆死点，形成稳定支撑，确保工作机具与托架连接的稳定性和可靠性。
