The invention provides a hoisting method for a large-span hinged type herringbone steel arch. The hoisting method comprises the steps of conducting hinge joint connection, setting hoisting points, installing hoisting rings, determining the lengths of hoisting steel wire ropes, hoisting and the like. According to the hoisting method for the large-span hinged type herringbone steel arch, due to integral and multipoint hoisting, the technical problems that hinge pin installation in high attitude is difficult, high in construction cost, low in working efficiency and the like are effectively solved. In addition, due to the facts that two hoists are used for hoisting, multipoint hoisting is adopted, and the hoisting points are set reasonably, the situation that the herringbone steel arch deforms due to lack of rigidity in the hoisting process is avoided. Due to the fact that the hoisting steel wire ropes with suitable lengths are selected, the installation angle of the herringbone steel arch is effectively controlled, and two column feet is made to be positioned on bases easily.

A water tube bearing device of a vehicle radiator core assembling machine mainly comprises a pressing cylinder, a pressing block, a bearing cylinder, a water tube bearing block and a photoelectric sensor. By means of the pressing function of the pressing block and the supporting function of the bearing block, most of radiator water tubes in a tube bin of the assembling machine can be controlled to be arranged on the bearing device and above the bearing device, and therefore few water tubes are reserved at the bottom of the tube bin, and the technical problem that the bottommost water tube is prone to being deformed in the striking process due to too large pressure is effectively solved. When the water tubes at the bottom of the tube bin are reduced to a certain number, the photoelectric sensor arranged at the bottom sends out a signal, the water tube bearing block and the pressing block move forward and backward step by step to release a part of the water tubes to the bottom of the tube bin, and meanwhile the water tubes above the bearing block fall onto the bearing block so as to guarantee continuity of work.
