Description

Technical Field

[0001] This utility model relates to the field of ship loader technology, specifically to a ship loader boom rail pressure roller. Background Technology

[0002] In port bulk cargo logistics, ship loaders are large machines used for loading materials onto ships at bulk cargo terminals, transferring materials from the shore to the vessel. A ship loader boom typically includes a telescopic boom and a fixed boom. The telescopic and fixed booms are often connected by a rolling pressure roller to reduce friction between the two booms, thus improving efficiency in cargo transport. The technical details can be found in invention patent application CN114194871A. The pressure roller usually includes a hub, axle, and flange. The hub houses bearings and connects other components, the axle bears the main load of the pressure roller, and the flange is in direct contact with the rail. However, the significant weight of the telescopic boom or the cargo results in considerable pressure on the pressure roller, which, over time, causes the pressure roller to squeeze the rail, leading to rail edge deformation and a "rail biting" phenomenon, shortening the rail's lifespan.

[0003] Therefore, it is necessary to design and develop a rail pressure roller for the ship loader boom to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to optimize the structural design of the pressure roller, enhance its load-bearing capacity, reduce uneven pressure distribution on the track, and alleviate the problem of the pressure roller "biting" the track edge.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A rail pressure roller for a ship loader boom includes a hub, a cylinder inside the hub, a bearing coaxially arranged inside the cylinder, a plurality of hydraulic rods arranged radially in a circular array on the outer periphery of the cylinder, the ends of the plurality of hydraulic rods being connected to a common annular member, the hydraulic control systems of the plurality of hydraulic rods being connected in series, and a rim being provided on the outer periphery of the annular member.

[0007] In a preferred embodiment, the number of the plurality of hydraulic rods is not less than four.

[0008] Furthermore, a first rubber layer is provided between the annular component and the wheel rim.

[0009] Furthermore, a second rubber layer is provided on the outer periphery of the rim, and the second rubber layer constitutes a tire.

[0010] Furthermore, the contact surface between the annular component and / or the rim and the first rubber layer is provided with protrusions, and the first rubber layer is provided with recesses adapted to the protrusions.

[0011] Furthermore, the cylinder is composed of multiple limiting plates, which are respectively connected to both sides of the hub. The limiting plates are connected to one end of the hydraulic rod, and the other end of the hydraulic rod is connected to the annular component.

[0012] Furthermore, the bearing is rotatably mounted on the pressure roller fixing seat, and guide wheel fixing seats are provided on both sides of the pressure roller fixing seat, with guide wheels arranged laterally on the guide wheel fixing seats.

[0013] Furthermore, a U-shaped component is provided between the guide wheel and the guide wheel fixing seat. The guide wheel is located at the opening of the U-shaped component. The guide wheel fixing seat is provided with a guide groove. Guide posts that are adapted to the guide groove are provided on both sides of the U-shaped component. An elastic component is provided between the U-shaped component and the guide wheel fixing seat. The elastic component causes the U-shaped component to reciprocate along the guide groove.

[0014] Furthermore, the guide wheel fixing seat is provided with an adjusting bolt, which passes through the guide wheel fixing seat and is connected to the elastic component via a snap ring. The adjusting bolt is threadedly engaged with the guide wheel fixing seat.

[0015] Furthermore, the elastic component is one of a spring, a pneumatic rod, or a hydraulic cylinder.

[0016] Furthermore, the guide wheel and the guide wheel mounting base are connected by a spherical surface.

[0017] The advantages and beneficial effects of this utility model are as follows:

[0018] 1. Multiple hydraulic rods are arranged in a radial array around the outer circumference of the bearing, and the ends of these hydraulic rods are connected to a ring-shaped component. Through a series hydraulic control system, the multiple hydraulic rods can evenly bear the force on the pressure roller and then distribute it to the surface of the pressure roller through the ring-shaped component, thereby adjusting the force relationship of the pressure roller and preventing "rail biting".

[0019] 2. A first rubber layer and a second rubber layer (forming a tire) are respectively provided between the annular component and the rim, and on the outer periphery of the rim. These rubber layers increase friction, prevent slippage, absorb impact and vibration, and protect the pressure roller from damage. The contact surfaces between the annular component and / or the rim and the first rubber layer are provided with protrusions and recesses that fit these protrusions to prevent relative rotation between the annular component and the rim after long-term operation.

[0020] 3. The bearing is rotatably mounted on the pressure roller fixing seat. Guide roller fixing seats are located on both sides of the pressure roller fixing seat, and guide rollers are arranged laterally on the guide roller fixing seats. U-shaped components and elastic elements are also installed between the guide rollers and the guide roller fixing seats. These components work together to allow the guide rollers to reciprocate along the guide groove, thereby adjusting the posture and position of the pressure roller and ensuring it maintains good contact with the track. The guide roller fixing seat is equipped with adjusting bolts and elastic elements. The adjusting bolts can adjust the position and pressure of the guide rollers, while the elastic elements provide additional support and cushioning. The guide rollers and guide roller fixing seats are connected by a spherical surface. This design allows the guide rollers to rotate and oscillate freely within a certain range, thus better adapting to changes and vibrations in the track and improving the adaptability and stability of the pressure roller.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0026] Example

[0027] Please see Figures 1-3This embodiment illustrates a rail pressure roller for a ship loader boom, comprising a hub 1, a cylinder 2 inside the hub 1, a bearing 3 coaxially arranged inside the cylinder 2, and six hydraulic rods 4 arranged radially in a circular array on the outer periphery of the cylinder 2. In a preferred embodiment, 6-8 hydraulic rods 4 can be arranged. The ends of each of the six hydraulic rods 4 are connected to an annular component 5. The hydraulic control systems of the six hydraulic rods 4 are connected in series. A rim 6 is provided on the outer periphery of the annular component 5, a first rubber layer 7 is provided between the annular component 5 and the rim 6, and a second rubber layer 8 is provided on the outer periphery of the rim 6, forming a tire. The contact surfaces of the annular component 5, the rim 6, and the first rubber layer 7 are provided with protrusions 19, and the first rubber layer 7 is provided with recesses adapted to the protrusions 19. The cylinder 2 is composed of multiple limiting plates 9, which are respectively connected to both sides of the hub 1. Each limiting plate 9 is connected to one end of a hydraulic rod 4, and the other end of the hydraulic rod 4 is connected to the annular component 5.

[0028] Bearing 3 is rotatably mounted on pressure roller fixing seat 10. Guide roller fixing seats 11 are provided on both sides of pressure roller fixing seat 10, and guide rollers 12 are laterally arranged connected to the guide roller fixing seats 11 via spherical surfaces. A U-shaped component 13 is also provided between the guide roller 12 and the guide roller fixing seat 11, with the guide roller 12 positioned at the opening of the U-shaped component 13. The guide roller fixing seat 11 is provided with a guide groove 14. Guide posts 15, adapted to the guide groove 14, are provided on both sides of the U-shaped component 13. An elastic component 16 is provided between the U-shaped component 13 and the guide roller fixing seat 11, causing the U-shaped component to reciprocate along the guide groove. An adjusting bolt 17 is provided on the guide roller fixing seat 11, passing through the guide roller fixing seat 11 and connected to the elastic component 16 via a snap ring 18. The adjusting bolt 17 is threadedly engaged with the guide roller fixing seat 11. Optionally, the elastic component can be a spring, a pneumatic rod, or a hydraulic cylinder.

[0029] The working principle of this utility model is as follows: In the initial state, all components are in a relatively static or conventional installation position. When the ship loader boom moves along the track, the entire pressure roller begins to function. First, the hub 1, driven by external power, begins to rotate around the bearing 3 relative to the pressure roller fixing seat 10, and the cylinder 2 also rotates accordingly. At this time, multiple hydraulic rods 4 connected to the outer periphery of the cylinder 2 work in concert based on the hydraulic system. Because their hydraulic control systems are connected in series and are connected to a common set of pressurized fluid, the contact pressure between the entire pressure roller and the track is adjusted. Specifically, when the pressure roller is subjected to vertical pressure, the vertical hydraulic rods 4 contract, while the remaining hydraulic rods extend due to the pressurization of the fluid. Specifically, some hydraulic rods that form an acute angle with the vertical hydraulic rods can provide a component force, allowing the vertically stressed hydraulic rods to evenly distribute this force to the contact surface between the pressure roller and the ground, thereby reducing deformation and preventing the pressure roller from deforming due to uneven force and causing rail wear. Dividing the cylinder into multiple limiting plates 9 can effectively prevent the cylinder from bending and deforming due to radial force, causing the pressure roller to shift as a whole. Specifically, it avoids excessive local force concentration, which can cause uneven force distribution and further reduce rail wear.

[0030] Because the guide wheel fixing seat 11 connects to the guide wheel 12 via a spherical surface and is equipped with a guide groove 14, a guide post 15, and an elastic component 16, when the pressure wheel encounters unevenness on the track or experiences a slight tendency to deviate due to other factors, the guide wheel 12 can swing within a certain range along the guide groove 14 at the opening of the U-shaped component 13. This ensures that the pressure wheel as a whole can travel relatively accurately along the track direction, preventing derailment and other abnormal situations. Simultaneously, the existence of the adjusting bolt 17 allows for adjustments to parameters such as the tightness of its connection with the elastic component 16 and the guide wheel fixing seat 11, based on the actual usage scenario. This further fine-tunes the working state of the guide wheel 12 to adapt to different working conditions, ensuring smooth and reliable operation of the entire pressure wheel on the track, thereby reducing or avoiding rail wear.

[0031] When the pressure roller travels on the track, the first rubber layer 7 and the second rubber layer 8 can absorb the vibration energy from the track to a certain extent, thus achieving a shock absorption effect. In addition, the protrusions 8 and the matching recessed structures on the contact surfaces of the annular part 5 and the wheel flange 6 with the first rubber layer 7 also help to disperse stress, buffer impacts, reduce the impact of vibration on the entire pressure roller and related components such as the ship loader boom, extend the service life of the equipment, and ensure its normal operation.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
