Description

Technical Field

[0001] The present invention relates to the technical field of ship unloaders, and in particular to a reclaiming device and a ship unloader. Background Art

[0002] Bucket chain ship unloaders have a long history of use at bulk cargo unloading terminals in ports. Their outstanding environmental advantages have helped them capture a significant market share. The bucket chain arm, a key actuator in the operation of a bucket chain ship unloader, moves up and down to load and unload materials at varying heights.

[0003] Traditional chain bucket arms are rigidly connected to the ship unloader structure. However, as ships rise and fall with the waves, the bottom of the cabin may collide with the bottom of the chain bucket arm, exerting a lifting force on the chain bucket arm. The chain bucket arm, rigidly connected to the ship unloader, transmits this lifting force to the ship unloader structure. If the lifting force exceeds the structural tolerance, the ship unloader structure will be permanently damaged. Therefore, the use of chain bucket ship unloaders is subject to many restrictions and can only be used in ports with relatively low waves or inland ports. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the vertical lifting force of the cabin movement caused by surge is transmitted to the ship unloader structure, causing damage to the ship unloader structure and further affecting the use environment of the ship unloader, thereby providing a material taking device and a ship unloader.

The flexible member is wound around each of the first redirecting pulley members and is suitable for driving the lifting and lowering of the material reclaiming head.

[0007] The material taking device further comprises: a material taking frame, which is arranged on the bearing portion and is suitable for guiding and accommodating the material taking head; the flexible lifting assembly is connected and arranged between the material taking frame and the material taking head.

[0008] The adjustment structure also includes: a second redirecting pulley group, which is arranged on the material picking rack. The second redirecting pulley group is provided with a plurality of second redirecting pulley members spaced axially, and the second redirecting pulley members are arranged corresponding to the first redirecting pulley members. The first redirecting pulley members and the second redirecting pulley members are staggered one by one along the winding path of the flexible member.

The first redirecting pulley groups are arranged in a horizontal direction, and the second redirecting pulley groups are arranged in a horizontal direction.

[0010] The adjustment structure also includes a third redirecting pulley group and a fourth redirecting pulley group connected to the bearing portion, one end of the flexible member is arranged on the third redirecting pulley group, and the fourth redirecting pulley group is arranged adjacent to the lifting drive member.

[0011] The third redirecting pulley set is respectively arranged along the same vertical direction as one set of the second redirecting pulley sets and one set of the first redirecting pulley sets, and their respective projections along the vertical direction are arranged along the same position or are arranged closely adjacent to each other;

[0012] and / or,

[0013] The fourth redirecting pulley set is respectively arranged along the same vertical direction as another set of the second redirecting pulley set and another set of the first redirecting pulley set, and their respective projections along the vertical direction are arranged along the same position or are arranged closely adjacent to each other.

[0014] The material taking head includes: a hopper body, suitable for digging materials; a hopper chain, which is arranged in a ring shape along the height direction, and a plurality of the hopper bodies are connected to the outer edge of the hopper chain; a hopper driving member, on which a driving wheel is connected, and the driving wheel is arranged in cooperation with the hopper chain. The hopper driving member is suitable for driving the driving wheel to rotate and driving the hopper chain to rotate along the height direction.

[0015] The material taking device further comprises: a cover shell, which is arranged on the outside of the material taking head and has a lower end arranged on the upper side of the lower end of the material taking head.

[0016] The bearing part is a running trolley, and / or the flexible member is a rope member.

[0017] The present invention provides a ship unloader, comprising: a frame body, on which a main beam is arranged; the above-mentioned material taking device, wherein the bearing part is arranged on the main beam and is suitable for moving along the main beam.

[0018] The technical solution of the present invention has the following advantages:

[0019] 1. The present invention provides a material picking device, a bearing part; a material picking head, arranged on the bearing part, suitable for moving along the height direction; a flexible lifting assembly, including a lifting drive part, a flexible part and an adjustment structure, the adjustment structure is provided with the flexible part along the circumference, suitable for carrying the flexible part and adjusting the direction of the flexible part, the flexible part is connected and arranged on the bearing part, and its end is connected to the lifting drive part, suitable for tightening or loosening under the action of the lifting drive part, and driving the material picking head to rise and fall relative to the bearing part.

[0020] By providing a flexible lifting assembly including an adjustment structure, the flexible member can be supported and the direction of the flexible member can be adjusted through the adjustment structure, so that the material picking device can be connected to the material picking head through the adjustment structure or the lifting drive member. When the driving force of the lifting drive member acts on the material picking head along the rope member, the flexible member is prevented from acting on the material picking head in a unidirectional manner, thereby ensuring the lifting stability of the material picking head. Furthermore, the coordinated arrangement of the flexible member and the lifting drive member can not only achieve the lifting of the material picking head relative to the supporting part by tightening or loosening the rope member, but also can absorb the impact when the material picking head is subjected to the vertical lifting force of the cabin movement caused by the surge, thereby achieving floating in the height direction and avoiding the external force being transmitted to the supporting part or the main structure of the material picking device. Therefore, this arrangement effectively overcomes the defect in the prior art that the vertical lifting force of the cabin movement caused by the surge is transmitted to the ship unloader structure, causing damage to the ship unloader structure and thus affecting the use environment of the ship unloader.

[0021] 2. The material picking device provided by the present invention, the adjusting device also includes: a second redirecting pulley group, which is arranged on the material picking frame, and the second redirecting pulley group is provided with a plurality of second redirecting pulley members spaced apart along the axial direction, the second redirecting pulley members are arranged corresponding to the first redirecting pulley members, and each of the first redirecting pulley members and the second redirecting pulley members are staggered one by one along the winding path of the flexible member.

[0022] By arranging the first redirecting pulley member and the second redirecting pulley member in an interlaced manner along the winding path of the flexible member, the interlacing density of the rope members between the two is increased, thereby improving the connection tightness of the first redirecting pulley group and the second redirecting pulley group, thereby ensuring the load-bearing stability of the material retrieving rack on the material retrieving head.

[0023] 3. The material picking device provided by the present invention, the adjustment structure also includes a third redirecting pulley group and a fourth redirecting pulley group connected and arranged on the bearing part, one end of the flexible member is arranged on the third redirecting pulley group, and the fourth redirecting pulley group is arranged adjacent to the lifting drive member.

[0024] By setting up a third redirecting pulley group, on the one hand, the load-bearing part is connected through the pulley group. Since the rope and the pulley are connected by sliding or rolling, the influence of the tensile stress of the rope on the setting position of the third redirecting pulley group can be effectively adjusted, avoiding stress damage to the connection position. On the other hand, the third redirecting pulley group is connected to the end of the flexible member, and one end is in a stable state. Only the lifting drive member on the other side is required to adjust the retraction and extension of the flexible member, avoiding the problem of difficulty in adjustment caused by the need to set the same lifting drive member at both ends and the need to start, stop and speed at the same time.

[0025] In addition, since the first redirecting pulley member and the second redirecting wheel member have a height difference with the bearing part, and the lifting drive member is connected to the end of the flexible member, it is necessary to receive the flexible member from one side of the first redirecting pulley member and the second redirecting wheel member. By setting up four redirecting pulley groups adjacent to the lifting drive member, the two are set flush or have a small height difference, so that the lifting drive member can drive the flexible member at the same height to extend and retract, thereby ensuring the stability of the lifting drive member's driving of the flexible member.

[0026] 4. The material retrieving device provided by the present invention is characterized in that it also includes a cover shell, which is arranged on the outside of the material retrieving head and the lower end of which is arranged on the upper side of the lower end of the material retrieving head.

[0027] By setting up a cover, and setting its lower end on the upper side of the lower end of the material taking head, on the one hand, the material taking head is wrapped to prevent material overflow during work; on the other hand, there is a height difference between the two ends, so that the lower end of the material taking head can be exposed to achieve normal transportation of the material below.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 1 - Figure 6 This embodiment provides a material-retrieving device, including: a carrying portion, a material-retrieving head 101 and a flexible lifting component.

[0042] Specifically, the bearing part is a running trolley 30, and wheels are provided at the lower end to cooperate with an external structure, such as the track of the movable arm on the main beam 20, and move along its length. As a convertible implementation method, the bearing part can also be other installation bases, such as a supporting platform or a fixed frame. In this embodiment, an opening is provided in the middle of the running trolley 30, which can accommodate part of the material head 101 to pass through.

[0043] The material taking head 101 is disposed on the bearing portion and is suitable for moving along the height direction. Specifically, the material taking head 101 includes several hopper bodies 1011 , a hopper driving member 1013 , and a hopper chain 1012 .

[0044] The hopper drive member 1013 is provided on the upper side of the overall structure of the material dispensing head 101, specifically a drive motor. In this embodiment, four groups of hopper drive members 1013 are provided, arranged in a square, and a drive wheel 1014 is provided on the inner side of the middle part, which can rotate under the action of the four hopper drive members 1013. This arrangement effectively increases the driving power of the drive wheel 1014.

[0045] The hopper chain 1012 is irregularly ring-shaped along the height direction, is meshed with the driving wheel 1014, and can rotate along the height direction under the action of the driving motor.

[0046] The hopper body 1011 is shaped like a bucket, with a flat end on one side connected to the hopper chain 1012 and a shovel end on the other side, which is arranged at an angle. In this embodiment, the shovel end is arranged in an inclined arc. During the rotation of the hopper chain 1012, along the rotation direction, the hopper body 1011 on the side of the hopper chain 1012 moving downward faces the opening downward, and at the lower end of the overall structure of the material taking head 101, it turns to horizontal movement to achieve the scooping of the material below. When the hopper body 1011 rotates along the hopper chain 1012 to the side moving upward, the opening of the hopper body 1011 turns upward to achieve the extraction of the material.

[0047] Furthermore, a plurality of hopper driving members 1013 are provided. In addition, the hopper chain 1012 is bent in the middle, and there are hopper auxiliary driving members and hopper driving auxiliary wheels to cooperate to further drive the stable operation of the hopper chain 1012.

[0048] In this embodiment, a cover shell 102 is further provided on the outside of the material taking head 101 . The cover shell 102 is cylindrical in shape, with the upper end extending to the bearing portion and the lower end being provided on the upper side of the lower end of the material taking head 101 .

[0049] By setting up the cover 102, and setting its lower end on the upper side of the lower end of the material taking head 101, on the one hand, the material taking head 101 is wrapped to prevent the material from overflowing during operation. On the other hand, there is a height difference between the two ends, so that the lower end of the material taking head 101 can be exposed to achieve normal transportation of the material below.

[0050] The flexible lifting assembly includes a lifting drive member 104, a flexible member 105 and an adjustment structure.

[0051] The lifting drive member 104 is a reel with a drive motor. This arrangement can drive multiple pulley groups to move synchronously with a single drive member, thereby improving the synchronization of the adjustment drive. As a convertible embodiment, the lifting drive member 104 can also be a drive motor.

[0052] The adjustment structure is provided with a flexible member 105 along the circumference, which is suitable for carrying the flexible member 105 and adjusting the direction of the flexible member 105. The flexible member 105 is a rope in this embodiment, specifically made of metal material such as a steel cable, or can be a cable.

[0053] The flexible member 105 is connected to the support portion, with its end connected to the lifting drive member 104. The flexible member 105 is adapted to be tightened or loosened by the lifting drive member 104, thereby driving the reclaiming head 101 to rise and fall relative to the support portion. Furthermore, in this embodiment, the lifting drive member 104 is disposed on the support portion, and the adjustment structure is at least partially disposed on the reclaiming head 101. Alternatively, the lifting drive member 104 may be disposed on the reclaiming head 101.

[0054] By providing a flexible lifting assembly including an adjustment structure, the flexible member 105 can be supported by the adjustment structure and the direction of the flexible member 105 can be adjusted, so that the reclaiming device can be connected to the reclaiming head 101 through the adjustment structure or the lifting drive member 104. When the driving force of the lifting drive member 104 acts on the reclaiming head 101 along the rope, the flexible member 105 is prevented from acting on the reclaiming head 101 in a unidirectional manner, thereby ensuring the lifting stability of the reclaiming head 101. Furthermore, the flexible member 105 and the lifting drive member 104 are arranged in a coordinated manner, so that the reclaiming head 101 can be lifted and lowered relative to the supporting part by tightening or loosening the rope. When the reclaiming head 101 is subjected to the vertical lifting force of the cabin movement caused by the surge, the impact can be absorbed by the flexible member 105, thereby achieving floating in the height direction, thereby avoiding the external force being transmitted to the supporting part or the main structure of the reclaiming device. Therefore, this arrangement effectively overcomes the defect of the prior art that the vertical lifting force of the cabin movement caused by the surge is transmitted to the ship unloader structure, causing damage to the ship unloader structure and thus affecting the use environment of the ship unloader.

[0055] The adjustment structure includes a first redirecting pulley set 106, which is arranged on the material reclaiming head 101 and includes a plurality of first redirecting pulley members arranged at intervals along the axial direction. The flexible member 105 is wound around each first redirecting pulley member and is suitable for driving the material reclaiming head 101 to rise and fall.

[0056] The material picking device also includes a material picking rack 103, which is frame-shaped and arranged on the upper side of the bearing part, specifically a square frame, which is convenient for setting up an adjustment structure. The material picking head 101 will enter the material picking rack 103 during the lifting process. The material picking rack 103 can accommodate the material picking head 101 and guide and constrain the movement of the material picking head 101 through the inner edge. The flexible lifting component is connected and arranged between the material picking rack 103 and the material picking head 101.

[0057] The adjustment structure also includes a second redirecting pulley group 107, which is arranged on the material picking rack 103, and a plurality of second redirecting pulley members are arranged at intervals along the axial direction. The second redirecting pulley members are arranged corresponding to the first redirecting pulley members, and each first redirecting pulley member and second redirecting pulley member is staggered one by one along the winding path of the flexible member 105.

[0058] By arranging the first redirecting pulley member and the second redirecting pulley member to be staggered one by one along the winding path of the flexible member 105, this arrangement increases the staggered density of the rope members between the two, thereby improving the connection tightness of the first redirecting pulley group 106 and the second redirecting pulley group 107, and ensuring the load-bearing stability of the material frame 103 on the material head 101.

[0059] Furthermore, the number of first bend pulley members within a single group is less than the number of second bend pulley members. In this embodiment, the difference is one. This arrangement allows the flexible member 105 to pass between the first and second bend pulley members and then extend from the second bend pulley member to the load-bearing portion. The extension length of the flexible member 105 between the two is constant, thereby improving the operational stability of the fixed end of the flexible member 105 and the end connected to the lifting drive member 104.

[0060] In this embodiment, the adjustment structure includes two sets of first redirecting pulley assemblies 106 and two sets of second redirecting pulley assemblies 107, which are arranged in a one-to-one correspondence. The corresponding first redirecting pulley assemblies 106 and second redirecting pulley assemblies 107 are equally spaced. The two sets of first redirecting pulley assemblies 106 are arranged horizontally, and the two sets of second redirecting pulley assemblies 107 are arranged horizontally. This arrangement prevents lateral unbalanced force on the reclaiming head 101 and improves the stability of the reclaiming head 101 when it is raised and lowered relative to the reclaiming frame 103.

[0061] The adjustment structure further includes a third redirecting pulley assembly 108 and a fourth redirecting pulley assembly 109 connected to the bearing portion. One end of the flexible member 105 is disposed on the third redirecting pulley assembly 108. The fourth redirecting pulley assembly 109 is disposed adjacent to the lifting drive member 104. In this embodiment, the third redirecting pulley assembly 108 and the fourth redirecting pulley assembly 109 are disposed on either side of the reclaiming head 101.

[0062] In this embodiment, the fourth bend pulley assembly 109 is flush with the lift drive 104. As an alternative embodiment, the fourth bend pulley assembly 109 can be spaced apart from the lift drive 104 and have a height difference. As an alternative embodiment, the third bend pulley assembly 108 can be omitted, and the flexible member 105 can be directly connected to the support portion. As another alternative embodiment, the fourth bend pulley assembly 109 can be omitted, and the flexible member 105 from the third bend pulley assembly 108 can be directly connected to the lift drive 104.

[0063] By setting up the third redirecting pulley group 108, on the one hand, the load-bearing part is connected through the pulley group. Since the rope and the pulley are connected by sliding or rolling, the influence of the rope tensile stress on the setting position of the third redirecting pulley group 108 can be effectively adjusted to avoid stress damage to the connection position. On the other hand, the third redirecting pulley group 108 is connected to the end of the flexible member 105, and one end is in a stable state. Only the lifting drive member 104 on the other side is required to adjust the retraction and extension of the flexible member 105, avoiding the problem of difficulty in adjustment caused by the need to set the lifting drive member 104 at both ends and the need to start, stop and speed at the same time.

[0064] In addition, since the first redirecting pulley member and the second redirecting wheel member have a height difference with the bearing part, and the lifting drive member 104 is connected to the end of the flexible member 105, it is necessary to receive the flexible member 105 from one side of the first redirecting pulley member and the second redirecting wheel member. By setting up four redirecting pulley groups adjacent to the lifting drive member 104, the two are set flush or have a small height difference, so that the lifting drive member 104 can drive the flexible member 105 at the same height to extend and retract, thereby ensuring the stability of the lifting drive member 104 in driving the flexible member 105.

[0065] Furthermore, the third redirecting pulley set 108 is respectively arranged along the same vertical direction as the corresponding second redirecting pulley set 107 and the first redirecting pulley set 106, and their respective projections along the vertical direction are arranged adjacent to each other, or can be arranged at the same position.

[0066] The fourth redirecting pulley set 109 is arranged along the same vertical direction as the corresponding second redirecting pulley set 107 and the first redirecting pulley set 106. Their respective projections along the vertical direction are arranged adjacent to each other, and can also be arranged at the same position.

[0067] As a convertible embodiment, the third redirecting pulley group 108 is spaced apart from the adjacent second redirecting pulley group 107 and the first redirecting pulley group 106 in the vertical direction; or, the fourth redirecting pulley group 109 is spaced apart from the adjacent second redirecting pulley group 107 and the first redirecting pulley group 106 in the vertical direction.

[0068] This embodiment further provides a ship unloader, comprising a frame and the above-mentioned reclaiming device, wherein a main beam 20 is provided on the frame; a bearing portion of the reclaiming device is provided on the main beam 20 and can move along the main beam 20 .

[0069] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
