The invention relates to the field of bridge construction, in particular to inspection well hoisting equipment. The main component of the inspection well hoisting equipment provided by the invention is a longitudinal hoisting telescopic device; a transverse supporting device, a clamping device and a pressing self-locking mechanism are arranged. After the hoisting equipment is in place, a lifting rope is connected with a lifting lug of the longitudinal hoisting telescopic device, at the moment, the pressing self-locking mechanism is in a locking state, and the clamping arms are in an opening state. The clamp is placed outside the concrete inspection well needing to be hoisted, the bottom box and the top box of the pressing self-locking mechanism are pressed and separated through the self gravity of the clamp, at the moment, hoisting equipment hoists, drives the longitudinal hoisting telescopic device to move and drives the clamping device to clamp the inspection well, and the automatic hoisting process is achieved. And after the inspection well reaches the hoisting position accurately, the hoisting equipment is lowered, the distance between the fixing bolts is increased, the sliding cross beam moves inwards, the clamping device releases the inspection well, and the automatic hoisting process is achieved.
本申请涉及桥梁施工领域,尤其涉及一种检查井吊装设备。本申请提供的检查井吊装设备,其主要部件为纵向吊装伸缩装置;横向支撑装置,夹取装置,按压自锁机构。吊装设备就位后,采用吊绳与纵向吊装伸缩装置的吊耳连接,此时按压自锁机构处于锁紧状态,夹取臂处于张开状态。将夹具放入需要吊装的混凝土检查井外,利用夹具自重力使按压自锁机构的底盒与顶盒按压分离,此时吊装设备起吊,带动纵向吊装伸缩装置运动,带动夹取装置夹紧检查井,实现自动起吊过程。待检查井精确到达吊装位置后,吊装设备下放,使固定螺栓间距增大,滑动横梁向内运动,夹取装置放开检查井,实现自动脱吊过程。
