Abstract
The invention discloses a mud door top bracing structure of a dredger, which consists of three groups of top bracing structures, wherein each group of top bracing structure comprises a top bracing strut, a first toggle plate and a second toggle plate, the first toggle plate and the second toggle plate are symmetrically arranged on two sides of the bottom of the top bracing strut, the top of the top bracing strut of the three groups of top bracing structures are respectively fixed on a ship body strut, and the bottom of the top bracing strut is fixed on a ship body slope plate through the first toggle plate and the second toggle plate on two sides. The mud door top brace structure of the dredger has the advantages that the stress of the top brace is more effective and reasonable, the repeated strength analysis of the end toggle plate avoids overlarge stress of the end and slows down the generation of cracks, and the end toggle plate does not penetrate through the slope plate, so that the dredger is convenient to construct and build.
Description
Technical Field
The invention relates to a mud door shoring structure of a dredger.
Background
The dredger is an engineering ship, underwater earth and stone excavation is carried out by means of different working devices, the purposes of dredging, hydraulic filling and sand and soil material collection are achieved, and with the high-speed development of modern construction in China, the water transportation condition needs to be improved urgently to adapt to the entrance and exit of a large ship and the stop of a wharf; the mud door is used as an important component of the dredger, the construction and installation are difficult, the operation is frequent, the top bracing structure of the mud door is a key component construction for supporting the mud door, the design is reasonable, the opening and closing of the mud door are facilitated, the construction is convenient, and the service life is long.
Disclosure of Invention
The invention aims to provide a mud door shoring structure of a dredger, which is convenient for stress transmission when a mud door is opened and closed, simple in process and convenient for construction.
The technical scheme adopted by the invention for realizing the purpose is as follows: the utility model provides a dredge mud door shore structure, mud door shore structure comprises three group's shore structures, and every group shore structure includes shore pillar, first bracket and second bracket, the bottom both sides at the shore pillar are installed to first bracket and second bracket symmetry, the shore pillar top of three group's shore structures is fixed respectively on the hull pillar, and the bottom is fixed on the hull ramp plate through the first bracket and the second bracket of both sides.
The three groups of top bracing structures are fixed on the hull pillar in a conical shape.
According to the mud door top brace structure of the dredger, the stress of the top brace is more effective and reasonable, the end toggle plate is subjected to repeated strength analysis, the phenomenon that the end stress is too large and cracks are relieved is avoided, and the end toggle plate does not penetrate through the slope plate, so that the dredger is convenient to construct and build.
Drawings
Fig. 1 is a schematic view of the overall structure of a muddoor shoring structure of a dredger according to the present invention.
In the figure: 1. a shoring strut; 2. a first toggle plate; 3. a second toggle plate; 4. a shaft; 5. a hull strut; 6. a mud door pillar; 7. a mud door; 8. a hull slope plate.
Detailed Description
As shown in figure 1, the mud door top bracing structure of the dredger comprises three groups of top bracing structures, the three groups of top bracing structures are fixed on a ship body strut 5 in a conical mode, each group of top bracing structure comprises a top bracing strut 1, a first toggle plate 2 and a second toggle plate 3, the first toggle plate 2 and the second toggle plate 3 are symmetrically installed on two sides of the bottom of the top bracing strut 1, the tops of the top bracing struts 1 of the three groups of top bracing structures are respectively fixed on the ship body strut 5, the bottom of the top bracing structures is fixed on a ship body slope plate 8 through the first toggle plate 2 and the second toggle plate 3 on two sides, the ship body strut 5 is sleeved on a shaft 4, the tops of the two mud door struts 6 are connected with the shaft 4 and the ship body strut 5, the bottom of the two mud door struts 6 are connected on a mud door 7, in operation, the shaft 4 pushes the two mud door struts 6 to open or close a counter-force mud door 7, and the mud door is opened through the top bracing struts 1, the three groups of top bracing structures, The first toggle plate 2 and the second toggle plate 3 are transmitted to the ship body, the mud door shoring structure of the dredger is convenient for the transmission of stress when the mud door is opened and closed, the process is simple, the construction is convenient, the shoring stress is more effective and reasonable, the end toggle plate is subjected to repeated strength analysis, the overlarge end stress is avoided, the generation of cracks is slowed down, and the end toggle plate does not penetrate through the slope plate, so that the dredger is convenient to construct and build.
Claims (2)
1. The utility model provides a dredger mud door shore structure which characterized in that: the mud door shore structure comprises three group shore structures, and every group shore structure includes shore pillar, first bracket and second bracket, the bottom both sides at the shore pillar are installed to first bracket and second bracket symmetry, the shore pillar top of three group shore structures is fixed respectively on the hull pillar, and the bottom is fixed on the hull ramp plate through the first bracket and the second bracket of both sides.
2. The muddoor bracing structure for a dredger according to claim 1, wherein: the three groups of top bracing structures are fixed on the hull strut in a conical shape.
