Description

Technical Field

[0001] The invention relates to a scraping device for bulk cargo ship tank cleaning, belonging to the technical field of ship cleaning devices. Background Art

[0002] In the field of bulk carrier transportation, a large amount of cargo often sticks to the bulkhead inside the cabin, especially coal, bauxite and other easily sticky materials, which not only affects the loading efficiency of the ship, but also increases the difficulty and cost of cabin cleaning. The traditional cleaning method mainly relies on manual operation with loaders and excavators. Workers need to enter the cabin and use tools or manually remove the cargo residues stuck to the bulkhead, while loaders and excavators are mainly used to clean large or loose cargo.

[0003] However, this cleaning method of manual cooperation with traditional engineering machinery has significant problems. First, the efficiency of human-machine cooperation is low. Due to the limited space inside the cabin, the collaborative work between workers and machinery is often greatly restricted, resulting in slow cleaning progress. Secondly, human-machine cooperation has great safety risks. The internal environment of the cabin is complex, and there are many potential dangerous factors, such as cargo collapse, mechanical failure, etc., which may pose a threat to the life safety of workers.

[0004] In view of the above problems, there is an urgent need in the market for a device that can efficiently and safely clean the adhered cargo inside the bulk cargo hold. Summary of the invention

[0005] The purpose of the present invention is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0006] The technical solution provided by the present invention is as follows: a scraper device for cleaning a bulk carrier, comprising a bucket body, a connecting frame and a cleaning device, wherein the connecting frame and the cleaning device are both arranged on the bucket body, the connecting frame is used to connect with external equipment, the cleaning device comprises a scraper plate and a rotating drive mechanism, the scraper plate is located on one side of the connecting frame, the rotating drive mechanism is drivingly connected to the scraper plate, and the rotating mechanism is used to drive the scraper plate to rotate around the x-axis and / or around the z-axis.

[0007] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: a scraper device for cleaning a bulk carrier of the present invention integrates a bucket body, a connecting frame and a cleaning device, wherein the connecting frame is convenient for connection with external equipment (such as an excavator), and the cleaning device includes a scraper shovel plate rotatable around the x-axis and / or z-axis and a driving mechanism thereof, the bucket body can be flexibly controlled by the large and small arms of the excavator, and the scraper device can use the lower rotating driving mechanism to drive the scraper shovel plate to move in an arc trajectory after the bucket has excavated and cleaned in place, thereby effectively cleaning the materials in the cabin keel and significantly improving the cleaning efficiency.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the rotary drive mechanism includes a first rotary cylinder, a cylinder bracket and a second rotary cylinder, the cylinder body of the second rotary cylinder is fixed on the bucket body, the second rotary cylinder is transmission-connected to the cylinder bracket, the cylinder body of the first rotary cylinder is fixed on the cylinder bracket, the scraper shovel plate is transmission-connected to the first rotary cylinder, the first rotary cylinder can drive the scraper shovel plate to rotate around the z-axis, and the second rotary cylinder can drive the cylinder bracket, the first rotary cylinder and the scraper shovel plate to rotate synchronously around the x-axis.

[0010] The beneficial effect of adopting the above further scheme is that the first rotary cylinder can independently drive the scraper shovel to rotate around the z-axis. When the first rotary cylinder and the second rotary cylinder work together, they can jointly drive the scraper shovel to perform complex spatial movements. This dual-axis rotation design enables the scraper shovel to perform precise scraping operations according to a predetermined trajectory, ensuring that the keel area of ​​the cabin and other hard-to-reach corners can be effectively cleaned.

[0011] Furthermore, it also includes a first angle sensor, which is installed on the first rotating cylinder and is used to detect the rotation angle of the scraper blade around the z-axis.

[0012] The beneficial effect of adopting the above further scheme is that by real-time monitoring of the rotation angle of the scraper shovel, the control system can more accurately control the movement trajectory of the scraper shovel to avoid over-rotation or under-rotation, thereby ensuring the cleaning effect.

[0013] Furthermore, it also includes a second angle sensor, which is installed on the second rotating cylinder and is used to detect the rotation angle of the scraper blade around the x-axis.

[0014] The beneficial effect of adopting the above further scheme is that, similar to the first angle sensor, the second angle sensor provides real-time feedback of rotation around the X-axis, so that the control system can more comprehensively grasp the movement state of the scraper blade, further improving the accuracy and efficiency of cleaning.

[0015] Furthermore, two groups of the cleaning devices are included, and the two groups of the cleaning devices are respectively located on both sides of the connecting frame.

[0016] The beneficial effect of adopting the above further scheme is that both sides of the cabin can be cleaned simultaneously in one operation, which greatly improves the cleaning speed. In addition, this design also helps to maintain symmetry and reduce the stress concentration problem caused by one-sided cleaning.

[0017] Furthermore, a plurality of shovel teeth are provided at the front end of the bucket body.

[0018] The beneficial effect of adopting the above further scheme is that the setting of the shovel teeth enables the bucket to cut into the material more effectively during the cleaning process. In particular, when dealing with agglomerated or tightly adhered materials, the shovel teeth can play a role in breaking and loosening, creating favorable conditions for subsequent cleaning work of the scraper shovel plate.

[0019] Furthermore, the connecting frame includes a connecting plate and a connecting shaft, two connecting plates are relatively fixed at the rear end of the bucket body, and one or more connecting shafts are connected between the two connecting plates.

[0020] Furthermore, it also includes a control system, which is connected to the first rotating cylinder, the second rotating cylinder, the first angle sensor and the second angle sensor.

[0021] The beneficial effect of adopting the above further solution is that the control system can adjust the action of the oil cylinder in real time according to the feedback signal of the angle sensor, so as to ensure that the scraper blade moves according to a predetermined trajectory.

[0031] like Figure 1-Figure 4 As shown, a scraper device for cleaning a bulk carrier comprises a bucket body 1, a connecting frame 2 and a cleaning device 3, wherein the connecting frame 2 and the cleaning device 3 are both arranged on the bucket body 1, the connecting frame 2 is used to connect with external equipment, the cleaning device 3 comprises a scraper plate 9 and a rotating drive mechanism, the scraper plate 9 is located on one side of the connecting frame 2, the rotating drive mechanism is drivingly connected to the scraper plate 9, and the rotating mechanism is used to drive the scraper plate 9 to rotate around the x-axis and / or around the z-axis.

[0032] The rotary drive mechanism includes a first rotary cylinder 10, a cylinder bracket 12, and a second rotary cylinder 13. The cylinder body of the second rotary cylinder 13 is fixed on the bucket body 1. The second rotary cylinder 13 is connected to the cylinder bracket 12 in a transmission manner. The cylinder body of the first rotary cylinder 10 is fixed to the cylinder bracket 12. The scraper shovel plate 9 is connected to the first rotary cylinder 10 in a transmission manner. The first rotary cylinder 10 can drive the scraper shovel plate 9 to rotate around the z-axis. The second rotary cylinder 13 can drive the cylinder bracket 12, the first rotary cylinder 10, and the scraper shovel plate 9 to rotate synchronously around the x-axis. The drive mechanism enables the scraper shovel plate 9 to achieve a complex motion trajectory. The second rotary cylinder 13 is fixed on the bucket body 1 and connected to the first rotary cylinder 10 through the cylinder bracket 12. The first rotary cylinder 10 directly drives the scraper shovel plate 9 to rotate around the z-axis. At the same time, the second rotary cylinder 13 can drive the entire cylinder bracket 12 (including the first rotary cylinder 10 and the scraper shovel plate 9) to rotate around the x-axis. The first rotary cylinder 10 can independently drive the scraper shovel 9 to rotate around the z-axis. When the first rotary cylinder 10 and the second rotary cylinder 13 work together, they can jointly drive the scraper shovel 9 to perform complex spatial movements. This dual-axis rotation design enables the scraper shovel 9 to perform precise scraping operations along a predetermined trajectory, ensuring that the keel area of ​​the cabin and other hard-to-reach corners can be effectively cleaned.

[0033] The scraper device also includes a first angle sensor 11 and a second angle sensor 14.

[0035] The first angle sensor 11 provides real-time feedback of the rotation of the scraper plate around the z-axis, and the second angle sensor 14 provides real-time feedback of the rotation of the entire cylinder bracket 12 around the x-axis. The control system 4 can adjust the action of the first rotating cylinder 10 and / or the second rotating cylinder 13 in real time according to the feedback signals of the first angle sensor 11 and the second angle sensor 14 to ensure that the scraper plate 9 moves according to a predetermined trajectory, avoiding excessive or insufficient rotation of the scraper plate 9, thereby ensuring the cleaning effect.

[0036] The front end of the bucket body 1 is also provided with a plurality of shovel teeth 6. During the cleaning process, the bucket can cut into the material more effectively. Especially when dealing with agglomerated or tightly adhered materials, the shovel teeth 6 can play a role in breaking and loosening, creating favorable conditions for the subsequent cleaning work of the scraper shovel plate 9.
