Problems solved by technology

[0002] The construction of large-scale ships is assembled and welded in the dock after being manufactured in sections. During the assembly process of the dock, thousands of support piers are needed to support the weight of the entire ship and keep the reference plane stable. However, due to the outer surface of the hull (support surface ) has been painted. Although necessary protective measures have been taken, it is difficult to ensure that the paint on the supporting surface of the hull will not be damaged due to the welding of the assembly closing seam and other factors during the entire construction process. In order to solve the problem of supporting pier In the past, it was necessary to set up another supporting pier for repainting the paint on the top, and destroy the original supporting pier before repainting. This kind of repainting operation not only wastes materials, but also takes time and effort, which affects the progress and efficiency

Embodiment 1

[0028] The dock uses pier wood composite support pier, including cement pier 1, sand box pier 2, and composite wooden pad 3. A sand box pier 2 is placed on the cement pier 1, and a composite wood pad 3 is placed on the sand box pier 2 to form a pier wood composite support pier (see Figures 1 and 2). The cement pier 1 (see Figure 5-9) consists of concrete 4 pre-embedded upper edge protection angle steel frame 6, lower edge protection angle steel frame 7, side edge protection angle steel 5, lifting hole edge protection angle steel frame 8, lifting hole protection Hole shell plate 9 or hoisting beam 30 and the laid steel hook 10, wherein the embedded hoisting hole edge protection angle steel frame 8 and the upper orifice plate 11, the lower orifice plate 12 and the two sides of the orifice plate 13 constitute The hoisting hole shielding shell plates 9 are welded to each other. The sand box pier 2 (see Figure 12 , Figure 13 ), consisting of sand box body 14, sand box door 15,...

Embodiment 2

[0030] Embodiment two is basically the same as embodiment one, and its difference is to make large cement pier 1, and the hoisting beam 30 (seeing Fig. 3) is embedded in the cement pier 1, is respectively provided with baffle plate 32 by round steel 31 two ends, two The baffles 32 are evenly distributed with three partitions 33, and the baffles 32 and the partitions 33 are welded to the round steel 31. Two identical sandbox piers 2 are placed on the cement pier 1, and the two sandbox piers All place the combined wooden pad 3 (seeing Fig. 4) of hardwood on 2, other are identical.

[0031] When the pier wood combination support pier for the dock starts to support, the wedge wood pad 28 on the composite wooden pad 3 is exerted force (manual promotion), so that the wooden pad 29 on the composite wooden pad 3 is pushed against the hull, and tied with galvanized iron wire 34 The combined wooden pad 3 is connected on the lug 16 of the sand box pier 2, and the pier wood combined suppo...

Abstract

The invention provides a launching block combination supporting pier used for docks, which consists of a concrete pier made of a pre-embedded concrete side-protection angle steel frame and a steel bar hook, a block with sand box that has the sand box body with a sand box door filled with coarse sand and a combination wood pad consisting of a lower wood pad, a stow-wood pad and an upper wood pad. The block with sand box is placed on the concrete pier and the combination wood pad is placed on the block with sand box to form the launching block combination supporting pier. wherein, the concrete pier is provided with a hole for hoist or a lifting beam and the block with sand box is provided with a lifting lug, a plurality of concrete piers and blocks with sand box are lifted to the dock for assembly and the lower part of the ship hull is laid out as scheduled to protect the reference level to be stable and unchanged. A force is applied on the stow-wood pad of the combination wood pad when the support process begins, the combination wood pad touches against the ship hull and the pier is at working state; when the pier needs to be unloaded, the sand box door is opened to discharge the sand, and then the combination wood pad drops together with the sand and the pier is at non-working state. The pier has simple structure and can be unloaded at any time under high bearing state, which leads the painting work on the ship hull above the pier to be carried out normally, so the cost is low and the production efficiency can be improved.
