Description

Technical Field

[0001] This utility model relates to the field of fabric-laying device technology, and in particular to a fabric-laying device for a ship loader. Background Technology

[0002] Ship loaders are large bulk cargo handling machines used in bulk cargo terminals. A typical ship loader consists of a boom conveyor, transition conveyor, telescopic chute, tail car, traveling mechanism, gantry, tower, pitching mechanism, and slewing mechanism. For port bulk cargo, the telescopic chute is the most commonly used component. The telescopic chute is primarily used to load bulk cargo into the ship's hold, completing the material placement operation. However, currently, when using telescopic chutes, after the material enters the hold, it tends to accumulate into a cone-shaped pile, wasting space and reducing the utilization rate of the hold's volume. Changing the position of the telescopic chute to complete the material placement operation is cumbersome and can easily cause the chute to collide with the hold's inner walls, resulting in damage or safety accidents. Utility Model Content

[0003] This utility model discloses a material distribution device for a ship loader, which solves the problems of materials accumulating into a cone-shaped bulk pile after entering the ship's hold through a telescopic chute, reducing the utilization rate of the ship's hold volume, and the inconvenience of adjusting the position of the telescopic chute.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A fabric-laying device for a ship loader includes a telescopic chute, a connecting cylinder fixed to the bottom of the telescopic chute, a fixing ring fixed to the connecting cylinder, and a hoisting rope fixed to the fixing ring for driving the connecting cylinder to rise and fall; the discharge end of the connecting cylinder is connected to a fixed frame with a discharge hole at the bottom, the fixed frame is provided with a first electric telescopic rod, the telescopic end of the first electric telescopic rod is fixed with a movable frame that can move toward the discharge hole of the fixed frame, and a set of discharge pipes are connected to the outer wall of the movable frame.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The hoisting rope is driven by a drive device on the ship loader. The hoisting rope can move the connecting cylinder up or down through the fixed ring. After the connecting cylinder moves up or down, it can squeeze or stretch the telescopic chute to adjust the height of the fixed frame. When the material enters the connecting cylinder through the telescopic chute, the material enters the fixed frame through the discharge end of the connecting cylinder, and then is discharged through the discharge hole at the bottom of the fixed frame. When the material gathers into a cone-shaped pile in the ship's hold, the first electric telescopic rod can be activated to drive the moving frame toward the discharge hole of the fixed frame. When the moving frame blocks the discharge hole, the material in the discharge hole enters the moving frame and is then discharged through a set of discharge pipes, distributing the material evenly in the ship's hold. This utility model can effectively distribute the material evenly in the ship's hold, avoiding the accumulation of material into a cone-shaped pile in the ship's hold, improving the utilization rate of the ship's hold volume, and the operation process is simple and fast. At the same time, it can effectively avoid collision between the spherical shell and the inner wall of the ship's hold. Attached Figure Description

[0010] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0011] like Figure 1As shown, this utility model provides a fabric feeding device for a ship loader, including a telescopic chute 1, a connecting cylinder 2 fixed to the bottom of the telescopic chute 1, a fixing ring 3 fixed to the connecting cylinder 2, and a hoisting rope 31 for driving the connecting cylinder 2 to rise and fall fixed to the fixing ring 3; the discharge end of the connecting cylinder 2 is connected to a fixing frame 4 with a discharge hole at the bottom, the fixing frame 4 is provided with a first electric telescopic rod 5, the telescopic end of the first electric telescopic rod 5 is fixed with a movable frame 6 that can move toward the discharge hole of the fixing frame 4, and a set of discharge pipes 7 are connected to the outer wall of the movable frame 6. A slidably connected sleeve 8 is sleeved on the discharge pipe 7, and a set of second electric telescopic rods 61 is fixed on the movable frame 6, the telescopic end of the second electric telescopic rod 61 is fixed to the sleeve 8 by a fixing block; the set of discharge pipes 7 are arranged in a ring array. A baffle 62 located above the second electric telescopic rod 61 is fixed on the side of the movable frame 6 near the discharge hole of the fixing frame 4. The hoisting rope 31 is driven by a drive device on the ship loader (such as a winch). The hoisting rope 31 drives the connecting cylinder 2 to move up or down through the fixed ring 3. After the connecting cylinder 2 moves up or down, it can squeeze or stretch the telescopic chute 1. Adjust the height of the fixed frame 4 (the fixed frame 4 is circular, and the bottom of the fixed frame 4 is inclined towards the discharge hole so that the material can be discharged through the discharge hole better). When the material is continuously discharged through the discharge hole at the bottom of the fixed frame 4 and forms a cone-shaped pile of loose material in the ship's hold, the first electric telescopic rod 5 can be activated to drive the moving frame 6 to move towards the discharge hole of the fixed frame 4. When the moving frame 6 blocks the discharge hole, the material in the discharge hole enters the moving frame 6. Then, a set of discharge pipes 7 arranged in a ring array (the number of discharge pipes 7 in a set is at least four, and the discharge speed of the four discharge pipes 7 is the same as the discharge speed of the discharge hole on the fixed frame 4) can evenly discharge the material into the ship's hold, avoiding This design avoids the accumulation of materials in a cone-shaped pile within the hold. Furthermore, depending on the actual situation, activating the second electric telescopic rod 61 allows its telescopic end to move the sleeve 8 away from the moving frame 6 via a fixed block, facilitating better adjustment of the material's position within the hold and ensuring even distribution. A slider inside the sleeve 8 is fixed near the moving frame 6, and a sliding track adapted to the slider is provided on the outer wall of the discharge pipe 7. The first electric telescopic rod 5 and a set of second electric telescopic rods 61 are controlled by an external control panel, with the control program set according to actual conditions, which will not be elaborated upon here. When the moving frame 6 moves towards the discharge hole of the fixed frame 4, the baffle 62 blocks the material discharged through the discharge hole, preventing direct impact on one of the second electric telescopic rods 61 near the discharge hole on the moving frame 6, effectively protecting the second electric telescopic rod 61.

[0012] like Figure 1As shown, a buffer plate 41 located directly below the connecting cylinder 2 is fixed inside the fixed frame 4 by a fixed rod, and the top of the buffer plate 41 is arc-shaped. Fixed plates 9 are fixed on both sides of the bottom of the fixed frame 4, and the discharge hole at the bottom of the fixed frame 4 is located between the two fixed plates 9. The fixed end of the first electric telescopic rod 5 is connected to one of the fixed plates 9, and a U-shaped movable frame 63 is fixed on the movable frame 6 and slidably connected to the bottom of the other fixed plate 9. A connecting block 64 with an arc-shaped top surface is fixed to the bottom of the movable frame 6. A battery 21 is fixed on the connecting cylinder 2. When the material in the connecting cylinder 2 enters the fixed frame 4, it first contacts the buffer plate 41 to prevent the material from falling directly into the moving frame 6 and generating a large impact force after the moving frame 6 covers the discharge hole of the fixed frame 4. This effectively protects the connection between the telescopic end of the first electric telescopic rod 5 and the moving frame 6. The first electric telescopic rod 5 and the second electric telescopic rod 61 are both three-section telescopic rods. The open part of the moving frame 63 faces the discharge hole of the fixed frame 4. The moving frame 63 can increase the stability of the moving frame 6. When the material enters the moving frame 6, the connecting block 64 can guide the material to the feed end of a set of discharge pipes 7 respectively, avoiding the accumulation of material in the moving frame 6. The battery 21 can supply power to the first electric telescopic rod 5 and the second electric telescopic rod 61. The fixed end of the first electric telescopic rod 5 is fixed to a fixed plate 9 through a connecting plate.

[0013] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
