Description

Technical Field

[0001] The present application relates to a screw ship unloader, and in particular to a boom support device for a horizontal screw conveyor. Background Art

[0002] The screw ship unloader is a ship unloading machine with horizontal screw conveyors without flexible traction components, vertical screw conveyors and special reclaiming devices as the main working mechanism. It is a high-efficiency continuous bulk cargo ship unloader. Its advantages are that the operation process is carried out in a closed state, without dust pollution, and it is efficient and environmentally friendly. With the increasing attention paid to environmental protection and sustainable development around the world, the advantages of screw ship unloaders stand out in large-scale bulk cargo transportation equipment.

[0003] At present, for large-tonnage, long-distance screw ship unloaders, due to the long conveying distance, the spiral body of the horizontal screw conveyor adopts a segmented structure, and the two adjacent spiral bodies are connected by a boom support device.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] See also Figures 1 to 11 As shown, a hanger support device for a horizontal screw conveyor according to the present application is schematically shown, which is mainly used in a segmented horizontal screw conveyor to connect two adjacent segments of the screw.

[0054] According to an embodiment of the present application, a boom support device for a horizontal screw conveyor includes a boom assembly 100, a housing 200, a flange connection shaft 300, a bearing seat 400 and a bearing box 600.

[0055] Among them, the outer shell 200 is connected to the suspension rod assembly 100, the bearing box 600, the bearing seat 400 and the flange connection shaft 300 are located in the outer shell 200, the bearing seat 400 is installed at the lower end of the suspension rod assembly 100, the bearing box 600 is sleeved on the outside of the flange connection shaft 300, and a bearing 500 matching the flange connection shaft 300 is arranged in the bearing box 600. The bearing seat 400 is sleeved on the outside of the bearing box 600, and the outer surface of the bearing box 600 and the inner surface of the bearing seat 400 are spherically matched. Connecting flanges 301 are respectively arranged at both ends of the flange connection shaft 300, and the bearing box 600 and the bearing seat 400 are located between the two connecting flanges 301.

[0056] It should be noted that if Figure 1 , 2 As shown in 10, the boom assembly 100 is installed on the housing 200, and at least a portion of the boom assembly 100 extends into the housing 200 and is connected to the bearing seat 400. The two connecting flanges 301 of the flange connecting shaft 300 are used to connect with two adjacent sections of the spiral respectively. The housing 200 may include a tube body 203, and both ends of the tube body 203 are often open and are respectively provided with flanges 205. The bearing box 600, the bearing seat 400 and the flange connecting shaft 300 are located in the tube body 203, and the two flanges 205 are used to be sealed and connected with the outer tubes of the two adjacent sections of the spiral respectively, so that the conveying channels of the two adjacent sections of the spiral are connected.

[0057] In the boom support device of the present application, the bearing box 600 is sleeved on the outside of the flange connection shaft 300, the bearing 500 is arranged in the bearing box 600, the bearing 500 is matched with the flange connection shaft 300, the bearing seat 400 is sleeved on the outside of the bearing box 600, and the bearing seat 400 is connected to the boom assembly 100. Since the outer surface of the bearing box 600 and the inner surface of the bearing seat 400 are spherically matched, the bearing box 600 and the bearing seat 400 have a certain degree of rotational freedom in the radial and axial directions. In other words, during the high-speed rotation of the spiral body of the horizontal screw conveyor, the bearing box 600 and the bearing seat 400 of the present application can rotate appropriately in the radial and axial directions, so that the boom support device of the present application can realize the release of multiple degrees of freedom, so that it is not easy to cause the horizontal spiral flange connection shaft 300 to break due to the unbalanced torque generated by problems such as processing, manufacturing and installation, and has high safety and reliability and long service life.

[0058] In some embodiments, Figure 3 As shown, a limiting member 601 is provided on the outer surface of the bearing box 600, and a limiting hole 401 matched with the limiting member 601 is provided on the inner surface of the bearing seat 400. That is to say, the limiting member 601 extends into the limiting hole 401, and when the bearing box 600 and the bearing seat 400 can rotate radially and axially, the limiting hole 401 and the limiting member 601 cooperate to limit, thereby limiting the rotation range of the bearing box 600 and the bearing seat 400, limiting the radial and axial rotational freedom within the allowed range, preventing problems such as slipping, and being safer and more reliable.

[0059] Furthermore, the limiting member 601 is a cylindrical pin, and the limiting hole 401 is a cylindrical hole. Thus, the structure is simpler and more stable, and the operation is more convenient.

[0060] In some embodiments, the bearing 500 can be a split rolling bearing, which is not only convenient and quick to install and disassemble, but also has less wear on the rolling bearing, is less likely to cause rapid friction on the sliding bearing during the high-speed rotation of the flange connection shaft 300, and has a longer service life.

[0061] In some embodiments, the bearing box 600 and the bearing seat 400 may also adopt a split structure. Figure 6 and Fig. 9 As shown, the bearing box 600 can be composed of two halves, the upper and lower halves, and the bearing seat 400 can also be composed of two halves, the upper and lower halves. Thus, the installation and disassembly operations are convenient and fast.

[0062] In addition, the bearing box 600 and the bearing seat 400 adopt a split structure, which is also convenient for the installation of the limit member 601. The limit hole 401 can also adopt a blind hole to better prevent dust and other debris from entering between the bearing box 600 and the bearing seat 400, which is safer and more reliable.

[0063] In some embodiments, Figure 3 , 8 and Fig.11 As shown, a first annular groove 602 for accommodating a bearing 500 is provided in the bearing box 600, an oil nozzle 800 connected to the first annular groove 602 is provided on the bearing box 600, a first through hole 402 corresponding to the oil nozzle 800 is provided on the bearing seat 400, and the oil nozzle 800 is connected to a lubrication hose 700, which is used to be connected to a corresponding oil supply device.

[0064] When the bearing 500 needs to be lubricated, the lubricating oil is injected into the first annular groove 602 through the lubrication hose 700 and the oil nozzle 800 in turn, thereby performing point-to-point lubrication on the bearing 500 in the bearing box 600. Compared with the press-in lubrication of the sliding bearing, the operation is more convenient, the structure is more stable and reliable, and the oil consumption is effectively reduced.

[0065] Furthermore, an annular oil groove 501 is provided on the bearing 500 along the outer circumferential direction thereof, the first through hole 402 corresponds to the annular oil groove 501, and an oil hole 502 is provided in the annular oil groove 501. The oil hole 502 may be one, two or more, for example, the multiple oil holes 502 are evenly distributed along the circumferential direction of the annular oil groove 501. Thus, the lubricating oil output by the oil nozzle 800 enters the bearing 500 through the annular oil groove 501 and the oil hole 502, thereby ensuring better point-to-point lubrication of the bearing.

[0066] Furthermore, seals 603 are respectively provided between the bearing box 600 and the flange connection shaft 300. The seals 603 may be one, two or more, and the seals 603 are distributed at both ends between the bearing box 600 and the flange connection shaft 300. In other words, the seals 603 are used to seal both ends of the first annular groove 602, respectively, to prevent foreign dust and other debris from entering the bearing 500 and affecting the rotation of the bearing 500 or even damaging the bearing 500.

[0067] Furthermore, seals 603 are respectively provided at both ends between the bearing box 600 and the flange connection shaft 300, and second annular grooves 604 cooperating with the seals 603 are respectively provided at both ends of the bearing box 600, and the seals 603 are split skeleton oil seals, and the first annular groove 602 is located between the two second annular grooves 604. Among them, the seals 603 in each second annular groove 604 can be one, or more than two. Therefore, the use of skeleton oil seals makes installation and disassembly operations more convenient, can better prevent external dust and other debris from entering the interior of the bearing 500, and has a better sealing effect.

[0068] In some embodiments, Figures 1 to 5As shown, the suspension rod assembly 100 includes a vertical suspension rod 103 and a first top plate 101.
