The invention relates to the technical field of crawler excavator transportation equipment, in particular to a crawler excavator transportation pulley block. Comprising a vehicle body platform, a pressing rod locking mechanism, a hub connecting seat and walking wheels. The walking wheel is fixedly connected with the hub connecting seat, the hub connecting seat is rotationally connected with the rotating shaft through the bearing, and the rotating shaft is fixedly connected to the vehicle body platform; the hub connecting seat cannot rotate around the rotating shaft through the pressing rod locking mechanism, locking is achieved, and then rotation of the walking wheel is limited. After the crawler excavator is pressed on the vehicle body platform, the pressing rod locking mechanism is driven to move through pressure, unlocking is achieved, the hub connecting base can rotate around the rotating shaft, and then the walking wheels can rotate. The self-locking function is achieved, the failure rate is low, practicability is high, mounting and dismounting can be fast, and using is convenient; the transportation speed of the excavator is increased, the transportation cost is reduced, and meanwhile damage to the road surface is eliminated.
本发明涉及履带式挖掘机运输设备技术领域,尤其涉及一种履带式挖掘机运输轮滑车。包括车体平台、压杆锁紧机构、轮毂连接座与走行轮;所述走行轮与轮毂连接座固接,轮毂连接座通过轴承与转轴转动相连,转轴固接在车体平台上;通过压杆锁紧机构使轮毂连接座无法绕转轴旋转,实现锁死,进而限制走行轮转动;履带式挖掘机压在车体平台上后,通过压力带动压杆锁紧机构运动,实现解锁,使得轮毂连接座能够绕转轴旋转,进而走行轮能够转动。具有自锁功能,故障率低,实用性强,能快速安装与拆卸,使用方便;提高了挖掘机运输速度,降低运输成本,同时消除了对路面的损坏。
