The invention relates to a rotary locking mechanism for battery replacement of a heavy truck. The mechanism comprises a pneumatic assembly, a rocker arm and a locking assembly, one end of the rocker arm is connected with the locking assembly, the other end of the rocker arm is connected with the pneumatic assembly, and the pneumatic assembly pushes and pulls the rocker arm to drive the locking assembly to rotate anticlockwise or clockwise, so that the locking assembly can lock or unlock a quick-change battery box. The structure is simple, operation is convenient, the locking assembly has pressing force when locking a quick-change battery, and it is guaranteed that locking is firm, safe and reliable. In addition, an unlocking screw rod is arranged on an air cylinder, so that when the locking mechanism cannot be automatically unlocked due to faults such as air leakage of an air source, manual unlocking can be realized by manually rotating the unlocking screw rod, and the safety and the reliability of the whole battery replacement heavy truck are improved.
本发明涉及一种重卡换电旋转式锁止机构,包括气动组件、摇臂和锁止组件,摇臂的一端与锁止组件连接,摇臂的另一端与气动组件连接,气动组件推拉摇臂,以带动锁止组件逆时针或顺时针转动,使锁止组件能够实现对快换电池箱快速锁止或解锁,结构简单、操作方便,并且锁止组件对快换电池锁止时具有压紧力,保证锁止牢固、安全可靠。本发明还通过在气缸上设有解锁螺杆,以保证气源发生漏气等故障导致锁止机构无法自动解锁时,通过人工旋转解锁螺杆,能够实现手动解锁,提高整个换电重卡的安全性和可靠性。
