Embodiment Construction
[0026] Examples see figure 1 with figure 2 As shown, the auxiliary hoisting tool for the protective fence of the high-speed railway embankment includes two L-shaped support base plates 1 arranged at parallel intervals, two support side plates 2 vertically welded on the vertical limbs of the two L-shaped support base plates 1, two support plates welded The rotating pin shaft 3 between the outer ends of the side plates 2, the rotating sleeve 4 movably socketed on the rotating pin shaft 3, the lifting lug 5 welded vertically in the middle of the rotating sleeve 4 and the two supporting side plates 2 The reinforcing bar 6 between the middle part of the top edge.
[0027] The L-shaped support base plate 1 is welded by 10mm thick steel plate, including rectangular horizontal limbs and rectangular vertical limbs. The horizontal limbs and vertical limbs are welded and connected. The welds must meet the specification requirements. The height of the vertical leg is 150mm and the widt...

The invention discloses a high-speed railway roadbed protective fence piece auxiliary hoisting tool and a using method thereof, and relates to the field of building construction. The auxiliary hoisting tool comprises two L-shaped supporting bottom plates arranged in parallel in a spaced mode, two supporting side plates perpendicularly welded to vertical limbs of the two L-shaped supporting bottom plates, a rotating pin shaft welded between the outer ends of the two supporting side plates, a rotating sleeve movably connected to the rotating pin shaft in a sleeving mode, a lifting lug vertically welded in the middle of the rotating sleeve and a reinforcing rod is welded between the middle parts of the top edges of the two supporting side plates; the outer end faces of the supporting side plates are semicircular arc faces protruding outwards, and connecting holes are formed in the outer end portions of the supporting side plates, and two ends of the rotary pin shaft are correspondingly inserted into the connecting holes of the supporting side plates and are firmly welded. According to the tool and the method, the problems that in the prior art, a protective fence is difficult to install and position, unsmooth in line shape, difficult to control in precision, low in construction efficiency, poor in construction quality and the like are solved.
Description
technical field [0001] The invention relates to the field of building construction, in particular to an auxiliary hoisting tool for a high-speed railway embankment protective fence and a method for using the same. Background technique [0002] During construction, it is often encountered that the roadbed needs to be closed with a protective fence. In the prior art, in the construction of high-speed railway embankment protective fences, cranes are usually used for hoisting, but during the installation process, the crane has a limited operating range, frequent movements, and low construction efficiency; steel wire ropes can also be used to hoist reinforced concrete protective fence pieces, but the hoisting process Medium and large safety risks, low construction efficiency and easy to cause damage to the reinforced concrete protective fence. Especially in some mountainous areas, the installation of protective fences still has problems such as difficult positioning, uneven alig...
