Description

Technical Field

[0001] The utility model relates to the technical field of container turning machines, in particular to a hydraulic door opening and closing device for a container turning machine. Background Art

[0002] The purpose of the container tipper is to transport and load and unload various granular bulk materials such as grain, plastic, iron filings, mineral powder, etc. It is suitable for railway freight yards, docks, mines, grain depots, coal yards and other places.

[0003] The container tipping machine includes a bracket and a truss slidably connected to the bracket. The truss is provided with a grabbing structure for grabbing the container. When loading and unloading the container, it is inconvenient to open and close the door, especially when the door is facing upward. When the door is opened, special staff are required to climb up the ladder to open the door, or special equipment is required to be moved to one side of the container to open the door, which causes great trouble. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a hydraulic door opening and closing device for automatically opening and closing a box door, thereby improving the convenience of use.

[0005] The utility model is realized through the following technical scheme: a hydraulic door opening and closing device of a container turning machine, comprising a rotating plate hinged on a truss of the turning machine through a first hinge axis, the first hinge axis is coaxially arranged with the rotating axis of the container door, the rotating plate is hinged with a swing plate through a second hinge axis perpendicular to the first hinge axis, the swing plate is fixedly connected with a plug plate located between the door and the door locking rod, a first driving mechanism for driving the swing plate to swing around the second hinge axis is provided on the turning plate, and a second driving mechanism for driving the turning plate to rotate around the first hinge axis is provided on the truss.

[0006] In this solution, the rotating plate is driven to rotate by the second driving mechanism, so that the plug plate moves to the front of the box door, and the first driving mechanism is driven to drive the swinging plate to rotate around the second hinge axis, so that the plug plate is inserted between the box door and the box door locking rod. The rotating plate is driven to reverse by the second driving mechanism, and the plug plate is placed on the box door locking rod, thereby driving the box door to open. Similarly, when the second driving mechanism drives the rotating plate to reverse again, the plug plate pushes the box door to close.

[0007] As an optimization, the rotating plate includes a fixed horizontal plate and a vertical plate, the horizontal plate is axially connected with the first hinge axis, the vertical plate is axially connected with the second hinge axis, and the second hinge axis is located below the horizontal plate. In this optimization solution, the second hinge axis is located below the horizontal plate, with a larger range of motion, which is convenient for the swinging plate to swing.

[0008] As an optimization, the first driving mechanism includes a first oil cylinder, a transmission plate and a linkage plate, the transmission plate is hinged to the cross plate through a third hinge shaft, the transmission plate is hinged to one end of the linkage plate through a fourth hinge shaft located below the cross plate, the other end of the linkage plate is hinged to the swing plate through a fifth hinge shaft, one end of the first oil cylinder is hinged to the cross plate through a sixth hinge shaft, the other end of the first oil cylinder is hinged to the transmission plate through a seventh hinge shaft, the third hinge shaft, the fourth hinge shaft, the fifth hinge shaft, the sixth hinge shaft, and the seventh hinge shaft are all arranged perpendicular to the first hinge shaft. This optimization scheme drives the transmission plate to rotate around the third hinge shaft through the first oil cylinder, and the rotation of the transmission plate causes the linkage plate hinged thereto to pull the swing plate to move, so that the swing plate swings around the second hinge shaft, and the swing range of the swing plate is increased through the transmission connection between the transmission plate and the linkage plate.

[0009] As an optimization, the fourth hinge axis and the seventh hinge axis are located on both sides of the third hinge axis. This optimization scheme enables the transmission plate to form a lever structure that rotates around the third hinge axis, which is convenient for the first oil cylinder to drive the transmission plate to rotate, and the transmission plate can drive the linkage plate to rotate in a wider range, thereby increasing the swing range of the plug plate.

[0010] As an optimization, the fifth hinge shaft and the plug plate are located on both sides of the second hinge shaft. This optimization scheme enables the swing plate to form a lever structure that rotates around the second hinge shaft, making it easier for the linkage plate to drive the swing plate to rotate. The linkage plate can drive the swing plate to swing in a wider range, further increasing the swing range of the plug plate.

[0011] As an optimization, the cross plate includes a horizontal section extending horizontally and a bending section extending downwardly, the first hinge axis is located on the horizontal section, and the third hinge axis is located on the bending section. The bending setting of the cross plate of this optimization solution increases the movable gap between the first oil cylinder and the cross plate, which facilitates the telescopic activity of the first oil cylinder.

[0012] As an optimization, a mounting seat is fixedly connected above the transverse plate, the sixth articulation axis is axially connected to the mounting seat, and the sixth articulation axis is located between the seventh articulation axis and the first articulation axis. In this optimization solution, the first oil cylinder is articulated with the mounting seat to realize the articulation of the first oil cylinder and the transverse plate.

[0013] As an optimization, the second driving mechanism includes a second oil cylinder with one end hinged to the truss through an eighth hinge shaft, and the other end of the second oil cylinder is hinged to the rotating plate through a ninth hinge shaft, and the eighth hinge shaft and the ninth hinge shaft are both arranged parallel to the first hinge shaft. In this optimization scheme, the eighth hinge shaft and the ninth hinge shaft are both parallel to the first hinge shaft, so that the rotation direction of the second oil cylinder is the same as the rotation direction of the rotating plate, so that the second oil cylinder drives the rotating plate to rotate.

[0014] As an optimization, a limit plate is provided between the rotating plate and the truss, and the limit plate is fixed to the rotating plate. When the plug plate is located between the box door and the box door lock rod, the limit plate and the truss are arranged in close contact. In this optimization solution, the limit plate moves with the rotating plate. When the plug plate is located between the box door and the box door lock rod, the limit plate and the truss are arranged in close contact. On the contrary, when the limit plate rotates and fits the truss, the plug plate can be inserted between the box door and the box door lock rod, which is convenient for locating the stop position of the plug plate.

[0015] The beneficial effects of the utility model are as follows: the rotating plate is driven by the second oil cylinder to rotate around the first hinge axis, so that the plug plate moves to the front of the box door. When the limit plate and the truss are in contact, the first oil cylinder is driven to drive the setting of the transmission plate and the linkage plate, thereby increasing the swing range of the swing plate and making the swing plate rotate around the second hinge axis so that the plug plate is inserted between the box door and the box door locking rod. The rotating plate is driven by the second oil cylinder to reverse, and the plug plate is placed on the box door locking rod, thereby driving the box door to open. Similarly, when the second oil cylinder drives the rotating plate to reverse again, the plug plate pushes the box door to close. Since the first hinge axis is in line with the box door rotating axis, the box door is driven to rotate around the box door rotating axis during the rotation of the rotating plate, thereby realizing the opening or closing of the box door and improving the convenience of use.

[0023] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0024] like Figures 1 to 5 As shown, a hydraulic door opening and closing device of a container turning machine is used to open a door 9 of a container. The door 9 is provided with a door locking rod 91. The turning machine includes a bracket and a truss 8 slidably connected to the bracket. The truss is provided with a grabbing structure for grabbing the container. The turning machine and the door are both prior arts.

[0025] like Figure 5 As shown, the left and right ends of the truss 8 are fixedly connected with a base 23 extending outward, and the base 23 is hinged with a rotating plate 2 arranged on the same side as the door 9 through a first hinge axis 1. The first hinge axis 1 is coaxially arranged with the rotating axis of the door 9, and the first hinge axis is located above the container. Figure 3 As shown, the rotating plate 2 includes a fixed horizontal plate 21 and a vertical plate 22, and the first hinge axis 1 is axially connected to the horizontal plate 21. In this embodiment, the horizontal plate 21 includes a horizontal section 211 extending horizontally and a bending section 212 extending downwardly obliquely. The first hinge axis 1 is axially connected to the outer end of the horizontal section 211, and the top of the vertical plate 22 is fixedly connected to the bottom of the bending section 212 and extends downward.

[0026] The rotating plate 2 is hingedly connected to the swing plate 4 via a second hinge shaft 3 which is arranged perpendicularly to the first hinge shaft 1. Figure 3 As shown, the bottom end of the vertical plate 22 of this embodiment is axially connected to the second hinge axis 3 located below the horizontal plate 21. The swing plate 4 of this embodiment is arranged on the side of the vertical plate 22 close to the first hinge axis 1. The side wall of the swing plate 4 is fixedly connected to an extension plate 41 extending in the direction of the second hinge axis 3. The vertical plate 22 is hinged through the second hinge axis 3 and the extension plate 41.

[0027] The swing plate 4 is fixedly connected to a plug plate 5 located between the box door 9 and the box door locking rod 91. In this embodiment, the plug plate 5 is fixedly connected to the bottom rear side of the swing plate 4. The plug plate 5 and the extension plate 41 are arranged in parallel. The gap between the box door 9 and the box door locking rod 91 is located on the swing path of the plug plate 5.

[0028] The rotating plate 2 is provided with a first driving mechanism for driving the swinging plate 4 to swing around the second hinge shaft 3 , and the truss 8 is provided with a second driving mechanism for driving the rotating plate 2 to rotate around the first hinge shaft 1 .

[0029] The first driving mechanism includes a first cylinder 6, a transmission plate 10 and a linkage plate 12. The transmission plate 10 is hinged to the horizontal plate 21 through a third hinge shaft 11. In this embodiment, the third hinge shaft 11 is located at the outer end of the bending section 212. The third hinge shaft 11 and the first hinge shaft 1 are located on both sides of the vertical plate 22, and the transmission plate 10 and the swing plate 4 are located on both sides of the vertical plate 22.

[0030] One end of the transmission plate 10 is hinged to one end of the linkage plate 12 through the fourth hinge shaft 13 located below the cross plate 21, and the other end of the linkage plate 12 is hinged to the swing plate 4 through the fifth hinge shaft 14. The fifth hinge shaft 14 and the insert plate 5 are arranged on both sides of the second hinge shaft 3, so that the swing plate 4 forms a lever structure that rotates around the second hinge shaft 3, which makes it easier for the linkage plate 12 to drive the swing plate 4 to swing in a larger range, thereby increasing the swing range of the insert plate 5.

[0031] One end of the first oil cylinder 6 is hinged to the cross plate 21 through the sixth hinge shaft 15, and the other end of the first oil cylinder 6 is hinged to the other end of the transmission plate 10 through the seventh hinge shaft 16. The fourth hinge shaft 13 and the seventh hinge shaft 16 are located on both sides of the third hinge shaft 11, so that the transmission plate 10 forms a lever structure that rotates around the third hinge shaft 11, which is convenient for the transmission plate 10 to drive the linkage plate 12 to rotate in a larger range, thereby increasing the swing range of the plug plate 5. In this embodiment, a mounting seat 20 is fixedly connected above the cross plate 21, and the sixth hinge shaft 15 is axially connected to the mounting seat 20. The sixth hinge shaft 15 is located between the seventh hinge shaft 16 and the first hinge shaft 1. The fixed end of the first oil cylinder 6 is hinged to the mounting seat 20 through the sixth hinge shaft 15, and the first oil cylinder 6 extends toward the transmission plate 10. The telescopic end of the first oil cylinder 6 is hinged to the transmission plate 10 through the seventh hinge shaft 16. The third hinge axis 11 , the fourth hinge axis 13 , the fifth hinge axis 14 , the sixth hinge axis 15 , and the seventh hinge axis 16 are all arranged perpendicular to the first hinge axis 1 .

[0032] like Figure 5 As shown, the second driving mechanism includes a second oil cylinder 7 hinged on the truss 8 at one end through the eighth hinge shaft 17, and the other end of the second oil cylinder 7 is hinged to the rotating plate 2 through the ninth hinge shaft 18, and the eighth hinge shaft 17 and the ninth hinge shaft 18 are both arranged parallel to the first hinge shaft 1. In this embodiment, a fixing seat is fixedly connected to the middle vertical beam of the truss 8 and the side wall of the horizontal plate 21, and the fixed end of the second oil cylinder 7 is hinged to the fixing seat on the middle vertical beam through the eighth hinge shaft 17, and the second oil cylinder extends toward the rotating plate 2, and the telescopic end of the second oil cylinder 7 is hinged to the fixing seat on the horizontal plate through the ninth hinge shaft 18.

[0033] A limit plate 19 is provided between the rotating plate 2 and the truss 8 , and the limit plate is fixedly connected to the rotating plate 2 . When the plug plate 5 is located between the box door 9 and the box door locking rod 91 , the limit plate 19 and the truss 8 are fitted together. The limit plate 19 of this embodiment includes a fixed cross bar 191 and a vertical bar 192, one end of the cross bar 191 is fixed to the side wall of the cross plate 21, the other end of the cross bar 191 extends horizontally toward the truss 8 and is fixed to the top of the vertical bar 192, and the vertical bar 192 extends vertically downward. When the plug plate is located between the box door and the box door locking rod, the bottom end of the vertical bar 192 is in contact with the outer wall of the bottom beam of the truss 8, and the limit plate 19 moves with the rotating plate 2. When the plug plate is located between the box door and the box door locking rod, the limit plate and the truss are in contact with each other. Conversely, that is, when the limit plate 19 rotates and is in contact with the truss 8, the plug plate 5 can be inserted between the box door 9 and the box door locking rod 91, which is convenient for positioning the stop position of the plug plate.

[0034] In particular, the first oil cylinder 6 and the second oil cylinder 7 may also be replaced by air cylinders or electric push rods.

[0035] Working principle: When the utility model is in use, the second oil cylinder 7 is driven to contract, driving the rotating plate 2 to rotate around the first hinge axis 1, so that the plug plate 5 moves to the front of the box door 9. When the vertical rod 192 of the limit plate 19 and the outer wall of the bottom beam of the truss 8 are in contact, the second oil cylinder 7 stops contracting and drives the first oil cylinder 6 to extend and push the seventh hinge axis 16 at one end of the transmission plate 10, so that the transmission plate 10 rotates around the third hinge axis 11. The other end of the transmission plate 10 drives the linkage plate 12 to move through the fourth hinge axis 13, and the linkage plate 12 drives the swing plate 4 to move through the fifth hinge axis 14. The swing plate 4 rotates around the second hinge axis 3, and the plug plate 5 is inserted between the box door 9 and the box door locking rod 91, driving the second oil cylinder 7 to extend and drive the rotating plate 2 to reverse, and the plug plate 5 is placed on the box door locking rod 91. Since the first hinge axis 1 is colinear with the rotating axis of the box door 9, during the rotation of the rotating plate 2, the plug plate 5 drives the box door 9 to rotate around the rotating axis of the box door, thereby driving the box door to open. Similarly, when the second oil cylinder 7 contracts and drives the rotating plate 2 to reverse again, the plug plate 5 pushes the box door 9 to close, thereby realizing the automatic opening or closing of the box door 9, thereby improving the convenience of use.
