[0003] As a new type of dock unloading equipment, the scraper ship unloader has the remarkable characteristics of continuity, stability and high efficiency; however, whether the equipment can achieve the expected unloading effect, the design of the vertical scraper (feeding head) is particularly important, and it is necessary to take into account various unloading conditions and the swing of the bulk carrier itself.

Therefore, it needs to be improved. Utility Model Content

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a single ball joint swing structure of a vertical buried scraper. Figure 1 The single ball joint swing structure of the vertical buried scraper includes two machine groove side plates 1. In this embodiment, the two machine groove side plates 1 are installed on both sides of the vertical buried scraper, and swing following mechanisms 2 are installed on both sides of the machine groove side plates 1.

[0033] Reference Figure 1 Each machine slot side plate 1 is welded and fixed with reinforcing ribs 7 on the outside. The reinforcing ribs 7 can improve the overall or local strength of the structure and effectively enhance the bearing capacity of the machine slot side plate 1, so that it can better maintain the integrity of its shape and structure when subjected to external pressure or impact force, thereby ensuring the stable operation of the equipment and extending its service life.

[0034] Reference Figure 1 The swing following mechanism 2 includes two mounting seats 21, a hinge shaft 22 and a spherical bearing 23. The two mounting seats 21 are both mounted on the corresponding frame. The two mounting seats 21 are symmetrically arranged on both sides of the machine slot side plate 1. A trapezoidal rib plate 4 is welded and fixed on each mounting seat 21. The trapezoidal rib plate 4 optimizes the structure of the mounting seat 21, can effectively disperse and transmit the force received, and enhances the bearing capacity of the mounting seat 21. When the mounting seat 21 is subjected to a large load, the trapezoidal rib plate 4 can maintain the stability and integrity of the structure and reduce the possibility of deformation or damage caused by overload.

[0035] Reference Figure 1The two ends of the hinge shaft 22 are rotatably mounted on the two mounting seats 21 through bearings. In this embodiment, the hinge shaft 22 is mounted on the inner ring of the joint bearing 23, and the vertical scraper is mounted on the outer ring of the joint bearing 23. By introducing the joint bearing 23, the inner and outer rings of the joint bearing 23 have flexible rotation capabilities, which enables the scraper to absorb and disperse the axial force through the rotation of the joint bearing 23 when it is subjected to axial force. When the axial force acts on the scraper, the outer ring of the joint bearing 23 will rotate with the movement of the scraper, and the inner ring will remain relatively fixed with the hinge shaft 22, thereby realizing effective transmission and release of force.

[0036] Reference Figure 1 A buffer shaft device 3 is installed on the machine slot side plate 1. In this embodiment, there are two groups of buffer shaft devices 3 on each machine slot side plate 1, and the two groups of buffer shaft devices 3 are symmetrically installed on both sides of the machine slot side plate 1.

[0037] Reference Figure 2 Each buffer shaft device 3 includes a buffer column 31, a buffer spring 32 and a buffer block 33. The buffer column 31 is vertically installed on the machine slot side plate 1. A clamping plate 6 is installed on the machine slot side plate 1. The clamping plate 6 installs the buffer column 31 on the machine slot side plate 1 to ensure that the buffer column 31 can be firmly installed on the machine slot side plate 1, thereby ensuring the position accuracy of the buffer column 31 and being able to withstand various forces and vibrations during the working process, thereby providing necessary support for the buffer column 31.

[0038] Reference Figure 2 One end of the buffer spring 32 is fixed to the bottom of the buffer column 31, and the other end of the buffer spring 32 is fixed to the buffer block 33. In this embodiment, the buffer spring 32 has a damper, and the buffer block 33 is made of an elastic material, which can be rubber, to effectively protect the machine slot side plate 1 from direct impact and extend its service life, so that the entire scraper can operate more stably when subjected to external force, reducing structural deformation or damage caused by vibration or impact.

[0039] Reference Figure 2 A spacer sleeve 5 is installed on one side of each mounting seat 21 close to the machine slot side plate 1. In this embodiment, the hinge shaft 22 passes through the corresponding spacer sleeve 5, and the buffer block 33 is located above the corresponding spacer sleeve 5. The spacer sleeve 5 can eliminate the gap between the mounting seat 21 and the machine slot side plate 1, and reduce the possibility of dust entering between the mounting seat 21 and the machine slot side plate 1, thereby protecting the cleanliness and integrity of the inside of the equipment. In addition, the spacer sleeve 5 corresponds to the buffer block 33, and the buffer block 33 is a component in close contact with the spacer sleeve 5. It can provide additional buffering when the equipment is impacted or vibrated, reduce friction and impact between components, and extend the service life of the equipment.

[0040] Reference Figure 3A tilt sensor 8 is installed on the top of one of the machine slot side panels 1. The tilt sensor 8 provides real-time signal feedback, and the angle is displayed on the operation screen in the driver's cab. When the left and right swings to the extreme position (±3°), the vertical buried scraper is immediately lifted, and interlocking protection is performed through electrical control to prevent structural deformation. The interlocking protection mechanism effectively reduces deformation or damage of the structure due to excessive swinging, ensuring the safe operation of the equipment.

[0041] The implementation principle of the single-ball joint swing structure of a vertical buried scraper in an embodiment of the present application is as follows: during the operation of unloading and picking up materials, the vertical scraper starts to perform its picking up task. During the picking up process, due to factors such as the movement of the hull and the uneven distribution of materials, the vertical scraper may experience axial deflection; at this time, the joint bearing 23 begins to play its role, dispersing and absorbing these axial forces, reducing the impact on the equipment structure. At the same time, the buffer shaft device 3 installed on the machine slot side plate 1 serves as a mechanical limit protection mechanism, which limits the deflection through its elastic characteristics to prevent the scraper from swinging excessively and damaging the equipment. During the whole process, the inclination sensor 8 always monitors the inclination angle of the machine slot side plate 1 in real time, and feeds back the real-time signal to the driver's cab. The operating screen in the driver's cab will display these angle data in real time, so that the driver can clearly understand the posture changes of the machine slot side plate 1. Once the vertical scraper swings in the left and right directions When it moves to the set extreme position (±3°), the inclination sensor 8 will immediately trigger the interlocking protection mechanism of the electrical control system, and the system will automatically lift the vertical buried scraper to prevent it from continuing to swing; through the setting of the swing following mechanism 2, which adopts the form of a joint bearing 23, the overall structure is simplified, the installation and maintenance work are convenient, and the lateral force can be released to prevent over-constraint, reduce the deformation of the machine slot structure when it is subjected to external force, and can better adapt to various complex working environments, ensuring the stability and continuity of the material picking process. In addition, during the unloading process, the hull ups and downs caused by the roll or surge of the hull will cause the material state to change significantly. The single ball joint structure can realize swing following, so that the vertical buried scraper picking head can flexibly adapt to the changes in the material state, avoid the situation of uneven force, ensure the smoothness of material picking, improve the material picking efficiency, and reduce the equipment failure rate.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
