Problems solved by technology

The height of this kind of pier is mainly adjusted by adjusting the tightness of the wooden wedge. The adjustment of the tightness is mainly done by manually tapping the wooden wedge with a hammer or other tools. , each construction pier actually bears a large difference in load, which eventually leads to uneven stress on the segmented support

Embodiment 1

[0030] Such as Figure 1 to Figure 10 As shown, an adjustable pier includes two right-angle stepped side active units 2 and a wedge-shaped middle active unit 1, and the slopes of the two right-angled stepped side active units 2 are in contact with the wedge surfaces of the wedge-shaped middle active unit 1 respectively. , the contact surface can be appropriately coated with grease to reduce the sliding friction between the surfaces, so that the height of the adjustable pier can be naturally reduced when the pier is loose. The outer sides of the two right-angle terraced side active units 2 are provided with backing plates 3 . Among them, the right-angled terrace-shaped side active unit 2 is composed of a slant plate b11, a bottom plate b10, a first side plate 12 located on the left and right sides, a second side plate 13, two front and rear outer ribs b14, and a base plate located between the outer ribs b14. The wedge-shaped middle active unit is composed of a bottom plate a6, ...

Embodiment 2

[0038] Such as Figure 11 As shown, an adjustable pier includes two right-angle stepped side active units 2 and three wedge-shaped intermediate active units 1, and the slopes of the two right-angled stepped side active units 2 are in contact with the wedge surfaces of the wedge-shaped intermediate active units 1 respectively. Cooperating, the difference from Embodiment 1 is that the three wedge-shaped middle active units are provided with side plates between their respective bottom plates and sloping plates to provide lifting space, and also adjust the installation angle between the two sloping plates, namely Not necessarily 90°.

Abstract

The invention discloses an adjustable pier. The adjustable pier comprises two right-trapezoid-table shaped side flexible units and at least one wedge-shaped middle flexible unit. The bevel of each of the two right-trapezoid-table shaped side flexible units is in contact fit with the wedge face, adjacent to the corresponding bevel, of the corresponding wedge-shaped middle flexible unit. The wedge-shaped middle flexible units are in contact fit through the wedge faces of the wedge-shaped middle flexible units. The right-trapezoid-table shaped side flexible units and the wedge-shaped middle flexible unit are provided with adjusting holes and in series connection through studs. The two ends of the studs are provided with nuts and threads matched with the nuts. The adjustable pier is safe, reliable, capable of conducting height fine adjustment, simple, convenient and effortless to operate, high in work efficiency, further capable of being used in combination with other support piers, and flexible in combination, and thus the adjustable pier achieves the advantages of being high in fine adjustment ability, high in loading capacity, simple and convenient to operate and the like.

Description

technical field [0001] The invention belongs to a component supporting device in the heavy industry manufacturing industry, in particular to an adjustable pier. Background technique [0002] In the heavy manufacturing industry, especially the shipbuilding industry, dock / sway construction piers are widely used in the shipbuilding process. The construction pier is used to support the ship section during the closing stage of the ship. By adjusting the height of the construction pier to meet the closing welding conditions, the adjacent sections can be accurately aligned. [0003] In the past, shipbuilding piers were mainly composed of iron piers or cement piers and wooden wedges. Generally, a ship or an offshore platform needs to lay hundreds of construction piers. The height of this kind of pier is mainly adjusted by adjusting the tightness of the wooden wedge. The adjustment of the tightness is mainly done by manually tapping the wooden wedge with a hammer or other tools. ,...
