Problems solved by technology

In order to hoist the two pole beams, it is necessary to build a road for truck cranes. When the height of the groove pier from the ground is not too high, this method is not a big problem, but when the height of the groove pier from the ground is too high, or the groove pier is built in the middle of the river or In the swamp, truck cranes are not available, and the removal and turnover of the pole beams have become a major construction technical problem

Embodiment 1

[0036] Such as Figure 1~3 Among them, a method for deflecting and turning over in the air with a shoulder pole beam of a slotting machine is characterized in that it includes the following steps:

[0037] s1, the hoisting platform is set on the hoisting machine legs 4 on both sides of the slotting machine, the first hoisting machine 3 and the second hoisting machine 3' are respectively set on the hoisting platforms on both sides, and the bottom of the slotting machine beam 19 is set With electric hoist 2;

[0038] s2. Operate the hook of the second winch 3' and drop it from between the aqueduct body 6 and the door machine guide beam 7 on the right to connect with the single-hole lifting lug 20 of the pole beam 8, that is figure 1 In the B1 end, the hook for operating the electric hoist 2 falls from between the aqueduct body 6 and the left door machine guide beam 7 and connects with the upper hole of the double-hole lifting lug 21 of the pole beam 8. figure 1 In the A1 end, ...

Embodiment 2

[0053] A device used for the above-mentioned method of deflecting and turning over and transposing the shoulder pole beam of the slotting machine in the air. The hoisting platforms are arranged on the legs 4 of the slotting machine on both sides of the slotting machine, and the first hoisting platforms are respectively arranged on the hoisting platforms on both sides. The hoist 3 and the second hoist 3' are equipped with an electric hoist 2 at the bottom of the slot machine beam 19;

[0054] The first hoisting machine 3 and the second hoisting machine 3' are located between the two legs of the supporting legs 4 of the racking machine;

[0055] The drum centerlines of the first hoist 3 and the second hoist 3 ′ are parallel to the centerline of the aqueduct body 6 and perpendicular to the centerline of the shoulder beam 8 . The center of the hoist drum and the center of the steel suspender 5 are staggered with an appropriate distance to prevent interference friction between the ...

Abstract

The invention provides a method and device capable of realizing deflection, turn-over and transposition of carrying pole beams of an aqueduct erecting machine in the air. The method comprises the stepthat the carrying pole beams located at the bottom of an aqueduct body is overturned in the air in a narrow space position through arranged winches and an electric hoist to reach the top of the aqueduct body so that transportation of an aqueduct conveying truck is facilitated. The device is structurally characterized in that winding platforms are arranged on aqueduct erecting machine supporting legs on the two sides of the aqueduct erecting machine respectively, a first winch and a second winch are arranged on the winching platforms on the two sides respectively, and the electric hoist is arranged at the bottom of an aqueduct erecting machine beam; the first winch and the second winch are located between the two supporting legs of the aqueduct erecting machine supporting legs; and the center line of a winding drum of the first winch and the center line of a winding drum of the second winch are both parallel to the center line of the aqueduct body, and are both perpendicular to the center lines of the carrying pole beams. According to the structure and method, the carrying pole beams can be overturned from the bottom of the aqueduct body to the top of the aqueduct body without falling to the ground, and therefore the carrying pole beams can be conveniently placed on the aqueduct conveying truck to be conveyed.

Description

technical field [0001] The invention relates to the technical field of large-span aqueduct construction, in particular to a method and a device for deflecting and turning over in the air with a pole beam of a channel erecting machine. Background technique [0002] The water resource allocation project of a certain unit adopts a single-slot multi-side wall rectangular trough structure. The body of the aqueduct adopts a three-way prestressed reinforced concrete simply supported structure, each span is 30m long, and there are 164 spans in total. Cross-sectional dimensions of single tank: inner contour 6.5m×5.0m (net width×clear height), outer contour 8.7m×7.1~6.6m, floor thickness 0.4m, side wall thickness 0.5m, empty tank weight about 1200t. The supporting structure of the tank body is in the form of gravity pier-connected concrete pouring piles. The tank pier is composed of cap beams, pier body, caps and piles. The maximum pier height is 25m, and the minimum pier height is 7...
