Embodiment Construction

[0034] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-6 As shown in the figure, a construction method for pulling and releasing a guide rope without a closed helicopter includes the following steps:

[0036] 1) On the ground wire brackets 2 on the left and right sides of the two bases 380m across the tower 1, respectively hang the 305-type pay-off pulley 3 for the helicopter pay-off special guide rod, and hang one pay-off pulley 3 on each side; the pay-off pulley 3 passes through The triple plate 6 and the steel wire sleeve 5 are connected to the construction plate 4 under the front and rear main pipes at the hanging point of the iron tower in a V-type connection. The pay-off block 3 is connected to the V-shaped steel sleeve 5 through the triple plate 6 in a single-point shackle connection. The steel wire sleeve 5 Use two Ф22×2.5m galvanized pressed steel wire slee...

Abstract

The invention discloses a construction method of pulling and putting a guide rope by a helicopter without shipping stoppage, and relates to the field of the construction of pulling and putting the guide rope by the helicopter. Due to the rapid development of seaborne shipping industries and the multiplication of ship density, the contradiction between the shipping stoppage stringing construction and the water transportation becomes increasingly serious. The construction method comprises the steps that a tackle for paying-off is suspended on a crossing tower; a main sling of the helicopter is connected to the guide rope and a heavy hammer through a triangular yoke plate; a high-speed tension machine and a paying-off tripper car are arranged in the tension field, and the head of the guide rope is connected to a temporary anchor rope; the guide rope is connected to the triangular yoke plate, and the helicopter pulls the guide rope to fly with tensile force; the guide rope is maintained ata safe distance from the sea surface in the pulling and putting process; the helicopter successively unfolds and puts the guide rope into a rope groove of the tackle for paying-off over the two crossing towers; and the helicopter flies to the anchor rope field, and unhooks and anchors the guide rope on the ground, then an electric hook breaks away from the guide rope, and the helicopter suspendsthe heavy hammer to fly away. The method realizes the successful putting and putting construction of the guide rope under the condition of no shipping stoppage.

Description

technical field [0001] The invention relates to the construction field of helicopter pulling and releasing guide ropes, in particular to a construction method for pulling and releasing guide ropes for unsealed helicopters. Background technique [0002] In the past, due to the low density of shipping and the outdated wireline equipment, the sea-sealing measures were adopted for the construction of large-span wireline construction, and the impact on water transportation was not significant. However, with the development of the national economy, especially the rapid development of the maritime shipping industry, the density of ships has doubled. Therefore, the shield between the construction of the closed air line and the water transportation is becoming more and more serious. SUMMARY OF THE INVENTION [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provi...
