Description

Technical Field

[0001] This utility model relates to the field of port loading and unloading equipment technology, and in particular to a hydraulic cylinder device with balance compensation and a loading tower equipment. Background Technology

[0002] Loading towers are typically built within freight yards and can directly connect to railways, ports, or highways. They are primarily used to load goods or raw materials into trains, ships, or trucks, and are a crucial link in logistics transportation. Ore loading towers are automated loading systems specifically designed for loading and unloading solid materials such as ores. They are efficient, accurate, and environmentally friendly ore loading and unloading equipment, playing a vital role in ore logistics transportation. Therefore, many ports and terminals in China have adopted ore loading tower systems. These systems not only improve the efficiency and quality of ore loading and unloading but also reduce labor costs and energy consumption, providing strong support for port and terminal logistics transportation.

[0003] Loading towers are typically enclosed steel structures, including the main building, buffer silos, weighing silos, control rooms, electrical rooms, and transformer rooms. Currently, the gate cylinders in the buffer silos of ore loading towers are fixed with flange connections. When the gate support rollers wear down, their diameter decreases, and the buffer silo gate is filled with ore, the gate will shift downwards under the weight of the ore. Because the base and gate base are rigidly connected by flanges with no clearance, the cylinder rod bends under stress. When the cylinder operates, the bent rod causes an imbalance on both sides of the piston, leading to uneven wear of the seals, accelerating seal wear, causing internal leakage in the cylinder, and reducing its service life. Utility Model Content

[0004] This utility model addresses the problem that the hydraulic cylinders of current buffer chamber gates are fixedly installed, and when the cylinder rod bends, the bending cannot be compensated, leading to abnormal wear of the cylinder piston. It proposes a hydraulic cylinder device with balance compensation and a loading tower equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a hydraulic cylinder device with balance compensation, including a base, a hydraulic cylinder assembly, and a hinge seat. The base includes a first support frame and a second support frame. The first support frame is provided with an elastic component. The hydraulic cylinder assembly includes a hydraulic cylinder body and a hinge component that are fixedly connected to each other. The hinge component is hinged to the hinge seat so that the hydraulic cylinder body can rotate around a first axis. The hinge seat is hinged to the second support frame so that the hinge seat and the hydraulic cylinder body can rotate around a second axis. The first axis and the second axis intersect. The first support frame is used to support at least the hydraulic cylinder body, and the elastic component is in contact with the hydraulic cylinder body to provide elastic support to the hydraulic cylinder body.

[0007] Furthermore, the base includes a base plate, the first support frame includes a first support plate, one end of the first support plate is fixedly connected to the base plate, and the first support plate is perpendicular to the base plate. The first support plate is provided with a support hole for the cylinder body to pass through, and an elastic component is provided between the inner wall of the support hole and the cylinder body. The support hole and the cylinder body are coaxially arranged.

[0008] Furthermore, the elastic component includes an annular clamping member and multiple elastic bodies. The annular clamping member is disposed in the support hole and sleeved on the cylinder body. One end of the elastic body is connected to the inner wall of the support hole, and the other end is connected to the outer wall of the annular clamping member. The multiple elastic bodies are evenly distributed along the outer periphery of the annular clamping member.

[0009] Furthermore, an inclined reinforcing plate is provided between the first supporting plate and the bottom plate, with one end of the reinforcing plate fixedly connected to the first supporting plate and the other end fixedly connected to the bottom plate.

[0010] Furthermore, the hinge includes at least two first hinge shafts, which are connected to both sides of the cylinder body along a first direction. The center of the hinge seat is provided with a hinge port through which the cylinder body passes. The hinge port is provided with first hinge holes on both opposite side walls along the first direction. The first hinge shafts are engaged with the first hinge holes for hinge connection. The first direction is consistent with the direction of the first axis.

[0011] Furthermore, a first bearing is provided inside the first hinge hole.

[0012] Furthermore, the second support frame includes at least two second support plates, which are spaced apart along a second direction. Each second support plate is provided with a second hinge hole. The hinge seat is provided with a second hinge shaft at each of its opposite ends along the second direction. The second hinge shaft is hinged to the second hinge hole. The second direction is consistent with the direction of the second axis.

[0013] Furthermore, a second bearing is provided inside the second hinge hole.

[0014] This utility model also provides a loading tower device, including a hydraulic cylinder device with balance compensation as described above.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are:

[0016] This invention enables the cylinder body to rotate in two different directions by hinged connection between the cylinder body and the hinge seat, and hinged connection between the hinge seat and the second support frame. When the cylinder body is subjected to loads in different directions, it rotates in the corresponding direction to offset part of the load, achieving balance compensation of the cylinder body, protecting the cylinder body, and effectively extending the service life of the cylinder body. The elastic component provides elastic support to the cylinder body when it rotates, providing further buffering and protection for the cylinder body. Attached Figure Description

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] Please see Figures 1-6 A hydraulic cylinder device with balance compensation includes a base 100, a hydraulic cylinder assembly, and a hinge seat 400. The base 100 includes a first support frame and a second support frame. The first support frame is provided with an elastic component 200. The hydraulic cylinder assembly includes a hydraulic cylinder body 310 and a hinge component fixedly connected to each other. The hinge component is hinged to the hinge seat 400 so that the hydraulic cylinder body 310 can rotate about a first axis. The hinge seat 400 is hinged to the second support frame so that the hinge seat 400 and the hydraulic cylinder body 310 can rotate about a second axis. The first axis and the second axis intersect. The first support frame is used to support at least the hydraulic cylinder body 310, and the elastic component 200 is in contact with the hydraulic cylinder body 310 to provide elastic support to the hydraulic cylinder body 310.

[0028] In this embodiment, as Figure 1 , 2 As shown, taking the horizontal placement of the cylinder body as an example, the cylinder body 310 is mounted on the base 100. The cylinder body 310 and the hinge seat 400 are hinged through hinges on the cylinder body 310. The cylinder body 310 and the hinge seat 400 are hinged vertically, meaning the direction of the first axis is vertical, allowing the cylinder body 310 to rotate horizontally. Furthermore, in the hinge connection between the hinge seat 400 and the second support frame, the hinge seat 400 and the second support frame are hinged horizontally, meaning the direction of the second axis is horizontal, allowing the hinge seat 400 to rotate vertically. This also allows the cylinder body 310, hinged to the hinge seat 400, to rotate vertically as well. In the mounting structure of the cylinder body 310 and the base 100, the cylinder body 310 is installed in a horizontal direction. The first support frame supports the side of the cylinder body 310 away from the hinge seat 400. In addition, the elastic component 200 in the first support frame contacts the cylinder body 310 when it is supported. When the cylinder body 310 rotates, the elastic component 200 provides elastic support to the cylinder body 310 through elastic extension and contraction.

[0029] When the cylinder body 310 is subjected to a load, the cylinder body 310 can rotate in the vertical or horizontal direction through the hinge seat 400 and the second support frame, so as to automatically compensate for the deformation displacement caused by the force through rotation. When the cylinder body 310 rotates, the elastic component 200 can provide elastic support force to the cylinder body 310, which can effectively prevent the cylinder body 310 from rotating excessively or from wearing during rotation.

[0030] In the above structure, by setting the cylinder body 310 to be hinged to the hinge seat 400, and the hinge seat 400 to be hinged to the second support frame, the cylinder body 310 can rotate in two different directions. When the cylinder body 310 is subjected to loads in different directions, it rotates in the corresponding direction to offset part of the load, thereby achieving balance compensation of the cylinder body 310. This effectively prevents the cylinder body 310 from bending and deforming due to lack of deformation clearance, protecting the cylinder body 310 and effectively extending its service life. In addition, the elastic component 200 provides elastic support to the cylinder body 310 when it rotates, providing further buffering. The elastic deformation can further offset the load, and also effectively prevent wear caused by excessive rotation of the cylinder body 310, further protecting the cylinder body 310.

[0031] In the specific structure of the first support frame, such as Figure 1 , 3 As shown in Figure 4, the base 100 includes a base plate 110, and the first support frame includes a first support plate 120. One end of the first support plate 120 is fixedly connected to the base plate 110, and the first support plate 120 is perpendicular to the base plate 110. The first support plate 120 has a support hole 121 for the cylinder body 310 to pass through. The elastic component 200 is disposed between the inner wall of the support hole 121 and the cylinder body 310. The support hole 121 and the cylinder body 310 are coaxially arranged. The elastic component 200 includes an annular clamping member 210 and a plurality of elastic bodies 220. The annular clamping member 210 is disposed in the support hole 121 and sleeved on the cylinder body 310. One end of the elastic body 220 is connected to the inner wall of the support hole 121, and the other end is connected to the outer wall of the annular clamping member 210. The plurality of elastic bodies 220 are evenly distributed along the outer periphery of the annular clamping member 210.

[0032] In this embodiment, the base plate 110 is a rectangular plate structure and is placed horizontally. The first support plate 120 is also a rectangular plate structure and is placed vertically. The bottom end of the first support plate 120 is fixedly connected to one end of the upper surface of the base plate 110 along the length direction. The first support plate 120 has a support hole 121 penetrating its body in the middle. When the cylinder body 310 is installed on the base 100, and the axial direction of the cylinder body 310 is consistent with the length direction of the base plate 110... The cylinder body 310, with one end away from the hinge seat 400, passes through the support hole 121, thus providing support for the cylinder body 310. The cylinder body 310 is located on the upper side of the base plate 110. The first support plate 120 is perpendicular to the cylinder body 310. An elastic component 200 is provided on the inner wall of the support hole 121. When the cylinder body 310 passes through the support hole 121, the elastic component 200 exists between the outer surface of the cylinder body 310 and the inner wall of the support hole 121, thereby providing elastic support for the cylinder body 310. By assembling and connecting the first support plate 120 and the base plate 110 to provide support for the cylinder body 310, it is easy to install and remove. In addition, passing the cylinder body 310 through the support hole 121 provides more comprehensive support for the cylinder body 310, improving the support effect.

[0033] The elastic component 200 includes an annular clamping member 210. The inner ring diameter of the annular clamping member 210 is the same as or slightly smaller than the outer diameter of the cylinder body 310, thereby effectively clamping the cylinder body 310. During installation, as one end of the cylinder body 310 passes through the support hole 121, it also passes through the inner ring of the annular clamping member 210. Multiple elastic bodies 220 are connected between the annular clamping member 210 and the inner wall of the support hole 121. In this embodiment, four elastic bodies 220 can be provided. Of these four elastic bodies 220, two are vertically positioned opposite each other on the annular clamping member 210. On both sides, two additional elastic bodies 220 are horizontally positioned on opposite sides of the annular clamping member 210, so that the four elastic bodies 220 are evenly distributed on the outer periphery of the annular clamping member 210. When the cylinder body 310 is subjected to force and rotates, the annular clamping member 210 can effectively clamp the cylinder body 310, further protecting the cylinder body 310. Furthermore, the elastic bodies 220 in the rotational direction elastically contract under force to offset part of the load, effectively reducing the deformation of the cylinder body 310. The multiple elastic bodies 220 ensure that the elastic support force provided by the cylinder body 310 is more uniform when rotating in different directions. The elastic body 200 can be a rubber block or a spring.

[0034] In addition, such as Figure 3As shown, an inclined reinforcing plate 130 is provided between the first supporting plate 120 and the bottom plate 110. One end of the reinforcing plate 130 is fixedly connected to the first supporting plate 120, and the other end is fixedly connected to the bottom plate 110.

[0035] In this embodiment, two reinforcing plates 130 are provided, which are obliquely connected to both sides of the base plate 110 along the width direction. One end of the reinforcing plate 130 is fixedly connected to the first support plate 120, and the other end is fixedly connected to the base plate 110. This further improves the connection strength between the first support plate 120 and the base plate 110, effectively preventing deformation of the cylinder body 310 when it is subjected to load and the load is transmitted to the first support plate 120, thereby improving the stability of the support for the cylinder body 310.

[0036] Specifically, in this embodiment, the first support plate 120 and the base plate 110 can be connected by bolts, and the reinforcing plate 130 can also be connected by bolts.

[0037] In the specific structure of the hinge seat 400, such as Figure 5 , 6 As shown, the hinge includes at least two first hinge shafts 320, which are connected to both sides of the cylinder body 310 along a first direction. The hinge seat 400 has a hinge opening 410 in the middle for the cylinder body 310 to pass through. Each of the opposite side walls of the hinge opening 410 along the first direction has a first hinge hole 420. The first hinge shafts 320 are hinged to the first hinge holes 420. The first direction is consistent with the direction of the first axis. A first bearing 510 is provided inside the first hinge hole 420.

[0038] In this embodiment, as Figure 6As shown, the cylinder body 310 is fixedly connected to two sides along the vertical direction with first hinge shafts 320. The first hinge shafts 320 extend in the vertical direction, and their axial direction is consistent with the radial direction of the cylinder body 310. The hinge seat 400 can be a rectangular frame structure. The central part of the hinge seat 400 is a hinge port 410 that passes through its body. In addition, first hinge holes 420 are respectively provided on the two side walls of the hinge port 410 along the vertical direction. The first hinge holes 420 extend in the vertical direction, i.e., the first direction. When the cylinder body 310 passes through the hinge port 410 along its own axial direction, the first hinge shafts 320 and the first hinge holes 420 are engaged and inserted to achieve hinge, thereby realizing the rotation of the cylinder body 310 in the horizontal direction. By providing first hinge shafts 320 on opposite sides of the cylinder body 310 and hinged to the first hinge holes 420 of the hinge seat 400, this structure is simple, easy to implement, and ensures the stability of the cylinder body 310's rotation. Furthermore, to reduce friction during cylinder body 310 rotation and ensure smooth rotation, a first bearing 510 is provided in the first hinge hole 420. Additionally, the two ends of the hinge seat 400 with the first hinge holes 420 are detachable and can be bolted together for easy hinged connection to the cylinder body 310.

[0039] In the specific structure of the second support frame, such as Figure 1 , 5 As shown, the second support frame includes at least two second support plates 140, which are spaced apart along a second direction. Each second support plate 140 has a second hinge hole 141. The hinge seat 400 has a second hinge shaft 430 at each opposite end along the second direction. The second hinge shaft 430 is hinged to the second hinge hole 141. The second direction is consistent with the direction of the second axis. A second bearing 520 is provided inside the second hinge hole 141.

[0040] In this embodiment, two second support plates 140 are connected to opposite sides of the base plate 110 along the width direction. The upper end of each second support plate 140 has a second hinge hole 141 extending along the width direction of the base plate 110 (i.e., the second direction). Correspondingly, second hinge shafts 430 are connected to opposite ends of the hinge seat 400 along the second direction. During installation, the hinge seat 400 is installed between the two second support plates 140, and the second hinge shafts 430 are engaged with the second hinge holes 141 to achieve hinge, thereby enabling the cylinder body 310 to rotate vertically. This structure is simple and ensures the rotational stability of the cylinder body 310. Furthermore, the second support plates 140 and the base plate 110 can be connected and fixed with bolts, facilitating disassembly and installation. In addition, in order to reduce the friction when the hinge seat 400 rotates and ensure the smoothness of rotation, a second bearing 520 is provided in the second hinge hole 141.

[0041] In addition, a loading tower device includes a hydraulic cylinder device with balance compensation.
