A bidirectional movable reamer maintenance platform

Abstract

The present invention discloses a bidirectional movable auger maintenance platform, comprising a vertical movable body and a horizontal movable body. The vertical movable body can be moved in the up-and-down direction of the ship to match the upper and lower ear shaft positions of the bridge, and the horizontal movable body can be moved in the fore-and-aft direction of the ship. The vertical movable body is provided with a groove opening, which is larger than the outer contour of the ship's auger and is used to avoid interfering with the lifting and lowering of the auger. The horizontal movable body can be slidably mounted on the groove opening of the vertical movable body, so that the gap between the edge of the groove opening and the auger can be adjusted, so that it will not interfere with the lifting and lowering of the auger, and can fill the gap between the concave outer edge of the vertical movable body and the auger. The present invention improves the convenience of switching between the upper and lower positions of the auger maintenance platform for a double-ear shaft bridge auger suction vessel. The ship can complete the switching work independently without external assistance. At the same time, the horizontal movable body facilitates the replacement of blade teeth and the maintenance of the auger, thereby improving the flexibility and safety of the device.

Description

Technical Field

[0001] The invention relates to the technical field of dredging engineering, in particular to a bidirectional movable reamer maintenance platform. Background Art

[0002] In recent years, with the rapid development of the dredging industry, port and waterway dredging depths have continued to increase. To increase the dredging depth of cutter suction dredgers, dual-trunnion bridge technology has been adopted. This technology features two upper and lower bridge trunnion hinge points on the hull, allowing for switching positions to meet varying dredging depth requirements. When the bridge trunnion position is switched, the cutter maintenance platform also shifts to accommodate cutter maintenance and blade replacement.

[0003] At present, the cutter maintenance platforms of double-ear shaft cutter suction dredgers are mostly box-shaped structures with a connecting flange at the end and two upper and lower fixed flanges at the hull end. The connecting flange of the maintenance platform is connected to the fixed flange at the hull end by bolts. However, since the cutter maintenance platform weighs tens of tons, which far exceeds the lifting capacity of the ship-mounted crane, it is necessary to switch the upper and lower positions of the maintenance platform with the assistance of a floating crane or a shore crane. When the upper and lower positions of the maintenance platform need to be switched frequently, it will seriously restrict the performance of the ship and greatly increase the auxiliary costs. On the other hand, in order not to interfere with the lifting and lowering of the cutter, a groove needs to be opened at the front end of the maintenance platform. Since the lifting and lowering trajectory of the cutter is arc-shaped, there will be a large gap between the outer edge of the concave shape of the maintenance platform and the cutter after the cutter is lifted, which makes it very inconvenient to replace the blade teeth and poses a safety hazard. For this reason, it is very necessary to design a cutter maintenance platform that can move up and down and horizontally. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a bidirectional movable auger maintenance platform, which solves the problem that ships cannot complete the up and down switching of the auger maintenance platform and the inconvenience of replacing cutter teeth and repairing the shaft system by themselves.

[0028] Example

[0029] like Figure 1 As shown, an embodiment of the present invention provides a bidirectional movable reamer maintenance platform, comprising a vertical movable body 1 and a horizontal movable body 2, wherein the vertical movable body 1 can move along the up and down direction of the ship, and the horizontal movable body 2 can move along the fore and aft direction of the ship.

[0030] like Figures 2 to 5As shown, the vertical moving body 1 includes a main frame 1-1, vertical rollers 1-2, vertical slide rails 1-3, a vertical moving locking body 1-4, and a vertical driving body 1-5.

[0031] The front portion 1-1-1 of the main frame projects vertically in the shape of a U-shaped concave, forming a recessed opening at the bottom of the main frame 1-1. This opening is larger than the outer contour of the ship's cutter 3 and does not interfere with the lifting and lowering of the cutter 3. Due to the arc-shaped trajectory of the cutter 3's lifting and lowering, a large gap exists between the outer edge of the U-shaped vertical movable body 1 and the cutter 3 after the cutter 3 is lifted, making it difficult to replace cutter teeth. The horizontal movable body 2, however, can slide along the fore-aft direction of the ship and is slidably mounted within the recessed opening of the vertical movable body 1. When lifting and lowering the cutter 3, the horizontal movable body 2 slides to the fore-end, while sliding towards the aft-end for replacing cutter teeth or inspecting the shaft head. This eliminates interference with the lifting and lowering of the cutter 3 while also filling the gap between the outer edge of the U-shaped vertical movable body 1 and the cutter 3, allowing the gap between the edge of the recessed opening and the cutter 3 to be adjusted as needed. The rear portion 1-1-2 of the main frame projects horizontally and vertically in the shape of a U-shaped concave, forming a highly load-bearing frame structure.

[0032] The vertical slide rail 1 - 3 is in an I-shape, and one side wing plate of the vertical slide rail 1 - 3 is fixed to the hull gantry 4 .

[0033] At least two vertical rollers 1-2 are provided in the vertical direction along the rear end 1-1-3 of the main frame. The vertical rollers 1-2 include a roller plate 1-2-3, four vertical wheels 1-2-1, and two lateral wheels 1-2-2. One end of the roller plate 1-2-3 is fixedly mounted on the rear end 1-1-3 of the main frame. The vertical wheels 1-2-1 are rotatably mounted on the other end of the roller plate 1-2-3 and can roll within the "I"-shaped groove of the vertical slide rail 1-3. Two vertical wheels 1-2-1 are installed on each side of the roller plate 1-2-3, and roll up and down along the "I"-shaped groove of the vertical slide rail 1-3. The lateral wheel 1-2-2 is rotatably mounted on the upper side of the roller plate 1-2-3, and the lateral wheel 1-2-2 contacts the outer edge 1-3-2 of the other side wing plate of the vertical slide rail 1-3. A lateral wheel 1-2-2 is mounted on each of the left and right sides of the roller plate 1-2-3, and the lateral wheel 1-2-2 rolls along the outer edge 1-3-2 of the wing plate of the I-shaped vertical slide rail 1-3 to limit left and right deviation.

[0034] One end of the vertical drive body 1-5 is connected to the main frame 1-1, and the other end is connected to the hull gantry 4. Under the drive of the vertical drive body 1-5, the main frame 1-1 can move up and down along the vertical slide rail 1-3 and can also fix the main frame 1-1 in a certain position. The vertical drive body 1-5 can be a hydraulic cylinder, and the main frame 1-1 can be moved up and down by retracting and extending the hydraulic cylinder.

[0035] The vertical moving locking body 1-4 is located between the main frame 1-1 and the vertical slide rail 1-3. The vertical moving locking body 1-4 includes an earring 1-4-1 and a hook 1-4-2. The earring 1-4-1 is hinged to the rear end 1-1-3 of the main frame, and the hook 1-4-2 is fixedly connected to the vertical slide rail 1-3. A plurality of hooks 1-4-2 are arranged in the up-and-down direction along the vertical slide rail 1-3, and the earring 1-4-1 is hooked on the hook 1-4-2. When the vertical driving body 1-5 drives the main frame 1-1 to move in place, the vertical moving locking body 1-4 can further mechanically lock the cutter repair platform to prevent danger caused by the failure of the vertical driving body 1-5.

[0036] As Figure 6 and Figure 7 shown, the horizontal moving body 2 includes a horizontal frame 2-1, horizontal rollers 2-2, a horizontal slide rail 2-3, a horizontal moving locking body 2-4, and a horizontal driving body 2-5.

[0037] The vertical projection of the horizontal frame 2-1 is concave-shaped, and the horizontal slide rail 2-3 is in a "C" shape. The horizontal slide rail 2-3 is fixed on the main frame 1-1 of the vertical moving body 1. Horizontal rollers 2-2 are provided on the left and right sides of the lower part of the horizontal frame 2-1. The horizontal rollers 2-2 are stuck in the "C" shaped groove of the horizontal slide rail 2-3 and can roll along the "C" shaped groove surface.

[0038] One end of the horizontal driving body 2-5 is connected to the horizontal frame 2-1, and the other end is connected to the main frame 1-1 of the vertical moving body 1, so that the horizontal frame 2-1 can move horizontally along the horizontal slide rail 2-3 under the drive of the horizontal driving body 2-5 and can be fixed at a certain position. The horizontal driving body 2-5 is a hydraulic cylinder, and the horizontal frame 2-1 is driven to move back and forth by the retraction and extension of the hydraulic cylinder.

[0039] The horizontal moving locking body 2-4 is arranged on the left and right sides of the upper part of the horizontal frame 2-1 and is located between the horizontal frame 2-1 and the main frame 1-1 of the vertical moving body 1. The horizontal moving locking body 2-4 can further mechanically fix the horizontal frame 2-1 that has moved to a certain position to prevent accidental injuries to maintenance personnel when working on the horizontal frame 2-1.

[0040] The two-way movable cutter repair platform provided by the present invention does not require the assistance of a shore crane or a floating crane. The ship can complete the up-and-down position switching of the cutter repair platform by itself, and the horizontal moving body of the cutter repair platform can move along the head and tail direction of the ship, that is, it will not interfere with the lifting and lowering of the cutter and can fill the gap between the concave-shaped edge of the repair platform and the cutter; this cutter repair platform improves the adaptability, convenience, safety, and economy of ship construction.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein, and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
