Clamping key type tube drawing bench for drawing joint tube in underground wall section connection construction
The invention provides a clamping key type tube drawing bench used for drawing a joint tube in underground wall section connection construction, and relates to the field of hydraulic equipment, the clamping key type tube drawing bench comprises a jacking oil cylinder, an upper frame, a lower frame, a holding ring and a clamping key, the holding ring holds the joint tube tightly through the clamping key, and in the working process, the upper frame jacks to drive locking jacking, so that the purpose of drawing out the joint tube is achieved. The hydraulic and electrical control system is provided with large and small pump pulling modes according to the requirements of a pipe pulling process, and in order to guarantee the operation flexibility of the system, small pump micro-motion pulling and large pump rapid pulling can be independently operated; and in the state, when the pressure rises to the limit value, the system stops the operation of the small pump, and the large pump operation working mode is automatically switched into. The control system realizes automation and intelligence on the basis of meeting the construction reliability.
本发明提供一种用于地下墙段连接施工中接头管起拔的卡键式拔管机，涉及液压设备领域，包括顶升油缸、上架、下架、抱紧圈及卡键，抱紧圈抱紧街头管由卡键，工作过程中上架顶升带动锁紧顶升从而达到拔出接头管的目的。本发明液压及电气控制系统根据拔管工艺的需要，配置有大小泵起拔方式，为保证系统操作灵活性，小泵微动起拔与大泵快速起拔可独立运行；也可小泵微动起拔状态下切入自动起拔模式，在此状态下当压力升高达到限值后，系统停止小泵运行，自动切入大泵运行工作方式。控制系统在满足施工可靠性基础上实现自动化、智能化。
