The invention provides a non anchor block lifting and pushing device with loose hook jacks, which comprises the loose hook jacks, a door type frame, a front hanging device mounted on the door type frame, a back hanging device mounted on a to-be-lift and pushed object, and the lifting and pushing device, wherein the door type frame comprises a door type frame beam and door type frame vertical columns connected with two ends of the door type frame beam; lower ends of the door type frame vertical columns are hinged to a base of the door type frame; the base of the door type frame is placed on a platform guide rail and drives the door type frame to move back and forth; and the loose hook jacks are mounted on the front hanging device, the back hanging device, and the lifting and pushing device, and connected with a start hydraulic pump. According to the non anchor block lifting and pushing device, specifically, the SQD type loose hook jacks are utilized to conduct lifting operations for large devices in places with very narrow space or mountainous areas where large lifting devices can not enter; and as the motive power of the SQD type loose hook jacks comes from a hydraulic oil pump, the stress of each jack is even, so as to solve the potential safety hazard due to possible unsynchronized stress of a lifting winding machine.
Description
technical field [0001] The invention relates to a large-scale equipment hoisting construction technology, in particular to an anchor-free hoisting and pushing equipment with a pine clamp type jack. Background technique [0002] Places with very narrow spaces or mountainous areas where large lifting equipment cannot enter Due to the complex terrain, large lifting equipment cannot enter or there is not enough construction site, which brings difficulties to the construction of the project. The usual practice is to use the winch as the power equipment to hoist and push large-scale equipment without anchor points. The disadvantages are: 1. It is difficult to achieve synchronization in the control of the hoisting winch, and uneven lifting will inevitably occur during work, which is safe. Hidden danger. 2. The lifting hoist requires 7 to 8 people to operate normally. 3. The number of hoisting hoists used is large and expensive. 4. The amount of steel wire rope and block blocks i...
