Background
The cable-carried crane is a special construction device for the suspension bridge, and the working mode of the cable-carried crane is to span two main cables of the suspension bridge and lift and install steel beams under the bridge. Along with the increasing maturity of the design technology and the construction technology of the cable-carried crane in China, the convenience requirement of a construction party on the operation of the cable-carried crane is higher and higher on the premise of meeting the feasibility and the reliability of construction.
The cable-carrying crane is generally provided with a pressure-bearing shearing-resistant system, the pressure-bearing shearing-resistant block is arranged below the end beam, before the cable-carrying crane is lifted, the pressure-bearing shearing-resistant block is required to be pressed on a main cable in front of the cable clamp, the rear end part of the pressure-bearing shearing-resistant block is attached to the front end part of the cable clamp, on one hand, the gravity of the crane is transferred to the main cable through the pressure-bearing shearing-resistant block, and on the other hand, the sliding force caused by the gradient of the main cable is transferred to the cable clamp of the main cable. Because the positions of the cable carrying cranes are different when each section of steel beam is lifted, the front and back positions of the pressure-bearing shearing blocks on the end beams need to be adjusted frequently in order to ensure that the rear ends of the pressure-bearing shearing blocks are attached to the front ends of the cable clamps. In the prior cable-carried crane, the pressure-bearing shear block and the end beam bottom plate are usually connected by bolts, a plurality of bolts are required to be removed when the position of the pressure-bearing shear block is adjusted every time, the pressure-bearing shear block is shifted and positioned, then the bolts are tightened, and the operation steps are complicated. And because the sliding force needs to be uniformly applied by a plurality of bolts, the design value of the gap between the bolt holes cannot exceed 0.5mm, and the requirement on the alignment precision of the bolt holes is very high, so that greater inconvenience is brought to the positioning procedure. In summary, the pressure-bearing shear block connected by the bolts brings great difficulty to the operation of field workers and has certain influence on the construction efficiency of the cable-carrying crane.
