Description

Technical Field

[0001] The present invention relates to the technical field of material transportation equipment, in particular to a material unloading device. Background Art

[0002] The ship unloader is a high-efficiency continuous bulk cargo transmission equipment, whose main function is to continuously transfer the bulk materials carried in the ship to the storage area of the dock.

[0003] Typically, a ship unloader consists of a mainframe, which is supported on the dock by legs and other components. The mainframe includes an adjustment arm, which is equipped with at least a reclaiming mechanism. When reclaiming, the mainframe is supported on one side of the dock. A barge carrying material is docked at the dock's edge, and the adjustment arm extends into the ship's hold. The reclaiming mechanism continuously transports material from the hold to the outside, and the circulating conveying mechanism works together to deliver the material to the dock's storage area.

[0004] For ship unloaders, the material transportation path generally includes vertical and horizontal sections. In order to realize continuous transportation of materials, the current circulating conveying mechanism includes at least two parts: the first conveying section and the second conveying section. The first conveying section can realize vertical transportation of materials, and the second conveying section can realize horizontal transportation of materials. The material-picking component of the first transmission section picks up materials at the bottom of the adjusting arm, and then moves to the top of the adjusting arm under the transmission of the power component, and discharges the materials to the second conveying section, and then is transported to the corresponding storage area of the terminal under the transmission of the second conveying section.

[0005] The multi-section combination of the circular conveying mechanism has a relatively high cost of use. In addition, if one of the upstream conveying sections fails and the downstream conveying section continues to convey materials, the materials will accumulate at the receiving position of the failed conveying mechanism, leading to dangerous accidents.

[0006] Therefore, how to improve the safety of material transportation by ship unloaders is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

DETAILED DESCRIPTION

[0034] This paper investigates the technical problem of multiple conveyor mechanisms working together to transport materials from the ship's hold to the shore, which can lead to transmission hazards if the downstream conveyor mechanism fails. The proposed unloading equipment offers high safety and a simple structure.

[0035] Based on the above research findings, the present invention further explores and proposes a technical solution to solve the above technical problems.

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] This article takes the ship unloader as an example of unloading equipment to continue to introduce the technical solution and technical effects. Those skilled in the art should understand that the unloading equipment provided in this article can also be used in other unloading fields.

[0038] Please refer to Figures 1 to 6 , Figure 1 This is a structural diagram of a discharge device in one embodiment of the present invention; Figure 2 for Figure 1 A longitudinal sectional view of the connection position between the adjustment arm of the unloading equipment and the main frame is shown; Figure 3 For the present invention Figure 1 A partial schematic diagram of the unloading equipment shown; Figure 4 A partial cross-sectional view of a hopper and a chain hinged in a specific embodiment of the present invention; Figure 5 A partial cross-sectional view of a hopper and a chain hingedly connected in another specific embodiment of the present invention; Figure 6 for Figure 2 A in the middle is an enlarged schematic diagram; Figure 7This is a structural schematic diagram of the first arm in a specific embodiment of the present invention; Figure 8 This is a schematic structural diagram of the entire wear-resistant sleeve in a specific embodiment of the present invention; Figure 9 It is a schematic structural diagram of a wear-resistant sheet in a specific embodiment of the present invention.

[0039] The unloading equipment provided by the present invention includes a main frame 1. The main frame 1 primarily serves two functions: providing support and providing a mounting platform for other mechanisms. The bottom of the main frame 1 may be provided with legs 12, which cooperate with tracks on the support base to facilitate the relocation of the unloading equipment. The tracks on the support base may be parallel I-shaped or U-shaped tracks, and the legs 12 may accordingly be wheeled structures 13 that cooperate with the I-shaped or U-shaped tracks. Of course, the walking structure on the legs is not limited to the above description and may be tracked or other types.

[0040] Mainframe 1 is also equipped with an adjustment arm 2 and a circulating conveyor mechanism. The circulating conveyor mechanism is located along adjustment arm 2 and a portion of mainframe 1. Material extracted by the material-removing end of adjustment arm 2 is transported along adjustment arm 2 and mainframe 1 to a discharge port 5a provided on mainframe 1. The circulating conveyor mechanism can include a chain drive, a belt drive, or other transmission method. A detailed description of a circulating conveyor mechanism will be provided later.

[0041] The circulating conveyor mechanism of the present invention comprises a loading container and a conveyor line. The loading container is reversibly mounted on the conveyor line, meaning it can be flipped relative to the conveyor line so that its feed opening faces upward or downward. The conveyor line extends from the material-retrieving end of the adjustment arm 2 to a discharge opening 5a on the main frame 1. The discharge opening 5a can correspond to a storage area. Furthermore, after retrieving material, the loading container moves to the discharge opening 5a, maintaining its loading position.

[0042] That is to say, the loading container provided by the present invention can always be in the state of the end of loading before pouring the material. In this way, no matter how the transmission path between the material picking end and the pouring port 5a changes, the loading container is always in one state and the material will not spill. In this way, the material can be transported from the material picking position to the pouring port 5a with only one set of conveying lines. Compared with the multi-stage coordinated material conveying in the prior art, the present invention only uses one set of conveying lines to transport the material. Even if the conveying line fails, there will be no dangerous phenomenon of material accumulation, which greatly improves the safety of material transmission and has a simple structure.

[0043] In a specific embodiment, the conveyor line includes a transmission wheel system and an annular transmission member wound around the transmission wheel system. When the loading container is taking materials, there is a lateral spacing and a height spacing between the material taking end and the pouring port 5a. The part of the annular transmission member located between the material taking end and the pouring port 5a is configured as a non-linear transmission path. Figure 1Detailed description of the embodiment in which the conveyor line is configured as a vertical section and a horizontal section is shown in FIG. Of course, the transport of any zigzag conveying path can be realized by the above-mentioned unloading device in this article.

[0044] In the above-mentioned embodiments, the loading container of the unloading equipment can be a hopper 32 with an opening, and the hopper 32 is hinged to the annular transmission member. After the hopper takes the material, it moves to the discharge port 5a. Under the action of its own weight, the hopper 32 can be positioned with its opening facing upward. That is, when the hopper 32 moves with the chain 31, if no other force is applied to the hopper 32, the opening of the hopper 32 will always face upward. Similarly, after the hopper 32 is filled with material, it will still face upward under the action of its own weight. In this way, even if the path formed by the conveyor line has a curved broken line, the opening of the hopper 32 will be in an upward state before and after the turn, and the material in the hopper 32 will not be scattered. In this way, a set of conveyor lines can be used to transport materials from the material taking position to the material storage position.

[0045] Of course, in order to meet the needs of material picking and unloading, auxiliary material picking parts and auxiliary unloading parts must be installed in the unloading equipment, among which the auxiliary material picking parts are arranged at the material picking end, which are used to flip the hopper so that the opening is facing the material and the material opening is facing upward after picking up the material; that is, the auxiliary material picking parts change the opening state of the hopper to complete the material picking work.

[0046] The auxiliary unloading member is located near the discharge port 5a of the main frame 1 and is used to tilt the hopper so that its opening faces downward to complete the discharge. This auxiliary unloading member also changes the posture of the hopper 32, turning its opening downward to allow the material inside to be discharged into the discharge port. After the material inside the hopper 32 is discharged, the hopper 32 separates from the auxiliary unloading member and, under its own weight, returns to its upward-opening posture, where it continues to be transported by the annular transmission member.

[0047] In this article, the hopper posture can be changed by setting auxiliary material-taking parts and auxiliary material-discharging parts to meet the requirements of automatic material taking and discharging of the hopper during the transmission process of the annular transmission part.

[0048] Specifically, in the above embodiments, the auxiliary material picking parts may include a flip plate and a support plate. The flip plate is fixed to the adjusting arm and close to the material picking end. During the operation process, the hopper 32 first abuts against the flip plate and flips. Under the action of the support plate, the hopper starts to pick up materials from the opening downward and gradually flips to the opening upward to end the material picking.

[0049] In a specific embodiment, the flip plate includes a horizontal wall 81 and a vertical wall 82, and an overhanging portion 321 is provided at the lower end of the outer wall of the hopper 32. The overhanging portion 321 can abut against the horizontal wall 81 of the flip plate to realize the flipping of the hopper, that is, the horizontal wall 81 abuts against the overhanging portion 321 to push the hopper 32 to flip, and the outer wall of the hopper can abut against the vertical wall during the flipping process of the hopper 32.

[0050] The flip plate is generally L-shaped, with the horizontal wall 81 fixed to the adjustment arm 2 and the vertical wall 82 facing the hopper 32. Of course, the structure of the flip plate is not limited to the description herein.

[0051] The above embodiment provides an outwardly protruding extension 321 on the outer wall of the hopper 32 to abut against the horizontal wall 81 of the flip plate. As the hopper 32 moves downward, the hopper 32 is flipped. The structure is simple, and during the flipping process of the hopper 32, it can abut against the vertical wall 82 at least at a certain stage, thereby achieving the stability of the flipping of the hopper 32.

[0052] The auxiliary unloading member can be in the form of a baffle. The structure of the auxiliary unloading member is not shown herein, but this does not hinder the understanding of this article by those skilled in the art.

[0053] In a specific embodiment, the transmission wheel system includes a first transmission wheel provided at the material-retrieving end of the regulating arm 2 , and the abutment plate is a support shaft or a support plate 9 fixed to the end surface of the first transmission wheel.

[0054] That is to say, during the material taking process, the hopper 32 is restricted from rotating back to the upward opening position because the outer wall of the hopper 32 contacts the support shaft or the support plate 9, and can only rotate with the annular transmission member, so that the opening gradually rotates to the upward position, and the material taking work is completed at the same time.

[0055] This setting method is simple and easy.

[0056] In order to reduce the weight of the system as much as possible, a support plate may be preferably provided. A method for providing the support plate is given below.

[0057] In one specific embodiment, the support plates 9 are arranged in a plurality of circumferentially spaced intervals, with the outer edges of each support plate 9 forming discrete arc-shaped surfaces of equal diameter. When the support plates 9 restrain the hopper 32, the outer wall of the hopper 32 simultaneously abuts against at least one support plate 9. The support plates 9 are generally flat plates. Gaps are formed between adjacent flat plates, which prevents loose materials from becoming stuck, improving operational safety and saving energy.

[0058] This article takes the transmission wheel system including a sprocket group and the annular transmission member as a chain 31 as an example. The sprockets in the sprocket group are arranged to form a movement path of the chain 31. That is to say, according to the material transportation requirements, the sprockets in the sprocket group are arranged in a predetermined manner. After the chain 31 is installed and wound around each sprocket, it can move along the path.

[0059] In a specific embodiment, the sprocket group includes at least two groups of sprocket units, each sprocket unit includes two sprockets rotating coaxially, there are two chains, each chain is wrapped around the sprockets on the same side of each sprocket unit, and the hopper is simultaneously hinged to the two chains; the abutment plate is installed and fixed to the two sprockets of the same sprocket unit.

[0060] In this way, the abutment plate and the two sprockets form an integral structure, which is beneficial to improving the working stability and usage strength of the entire system.

[0061] in Figure 1 The diagram shows three sprocket units: a first sprocket unit 33, a second sprocket unit 34, and a third sprocket unit 35. Both the second sprocket unit 34 and the first sprocket unit 33 are fixed to the second arm support 22 of the adjustment arm, near the material removal end and the side of the first arm support 21, respectively. The third sprocket is located near the discharge port 5a of the main frame 1. The second sprocket unit 34 and the third sprocket unit 35 have a predetermined lateral spacing. In other words, the chain 31 changes direction when passing the second sprocket unit 34.

[0062] When the hopper 32 has finished taking the material, it moves upward along the adjusting arm 2 driven by the chain 31. After being transported to the position of the second sprocket unit 34, it turns and continues to run along the direction of the chain 31 determined by the second sprocket unit 34 and the third sprocket unit 35 (the horizontal direction in this article), and finally reaches the discharge port 5a.

[0063] Each sprocket unit includes two coaxial, synchronously rotating sprockets. Two chains 31 are wound around the sprockets on the same side of each sprocket unit. The hopper 32 is connected to and fixed to both chains 31. That is, the circulating conveyor mechanism can be equipped with two parallel chains 31, and the hopper 32 is fixed between the two parallel chains 31. The two chains 31 drive the hopper 32 synchronously, which can increase the stability of the system transmission.

[0064] This article also provides two specific implementations of the articulation between the chain 31 and the hopper 32.

[0065] Please refer to Figure 3 In the first specific embodiment, mounting seats 37 are provided on the opposite sides of the two chains 31, and an outward-extending hinge shaft 38 is formed on the mounting seat 37. A through hole for the hinge shaft 38 to pass through is provided on the corresponding side of the hopper 32, and a limiting member 39 is provided on the shaft section of the hinge shaft 38 located inside the hopper 32 to prevent the hopper from falling off the hinge shaft 38. Figure 3 FIG3 shows a specific structure in which the limiting member 39 is a bolt and a stop block. Of course, the limiting member 39 can also be a latch or other components.

[0066] Please refer to Figure 4In the second specific embodiment, a first mounting seat 37' is fixed to the side opposite to the chain 31 and the hopper 32, and a second mounting seat 39' is connected and fixed to the side opposite to the chain 31. The first mounting seat 37' is provided with a first step through hole, and its step surface faces the chain 31. The second mounting seat 39' is provided with a second step through hole, and its step surface faces the hopper 32. It also includes a pin 38', and the pin 38' includes a shaft body, and a first end and a second end are respectively provided at both ends of the shaft body, wherein the size of the first end and the second end can be larger than the shaft body, the first end is clamped in the through hole of the first mounting seat 37', and the second end is clamped in the second step through hole.

[0067] To minimize the chain layout, a fourth sprocket unit 36 can be installed on the main frame 1 or the adjustment arm. The chain bends through the fourth sprocket unit 36 and then extends to the first sprocket unit, thus converting horizontal operation to vertical operation. The fourth sprocket unit 36 can be constructed as a double sprocket to accommodate double-chain operation.

[0068] In addition, in order to maintain the balance of the unloading equipment, a counterweight can be provided at the end away from the mounting end of the adjusting arm 2 to balance the torque applied by the adjusting arm 2 to the main frame 1 .

[0069] In order to meet the support strength requirements of the main frame 1, a first support component 61, a second support component 62 and a third support component 63 can also be provided to support the end of the main support mounting adjustment arm 2 and the end of the counterweight setting.

[0070] In the above embodiments, the adjusting arm 2 can directly reciprocate in the vertical direction relative to the main frame 1, and the adjustment is fast, thereby improving the material taking efficiency, and the driving mechanism for realizing the movement of the adjusting arm 2 in the vertical height direction is relatively simple in structure.

[0071] In a specific embodiment, the adjusting arm 2 may include a first arm 21 and a second arm 22. The first arm 21 is installed on the main frame 1 and the two are limited in at least the vertical direction. The first arm 21 includes a longitudinally extending sleeve 211. The second arm 22 at least partially penetrates the inside of the sleeve 211. The second arm 22 reciprocates relative to the first arm 21 along the sleeve 211. That is to say, in this article, the first arm 21 and the main frame 1 cannot be relatively displaced at least up and down. The sleeve 211 on the first arm 21 forms a guide component for the relative movement of the second arm 22, thereby improving the directionality and movement stability of the second arm 22.

[0072] The lower end of the second arm 22 is a material taking end. According to the change of the material taking height, the second arm 22 is controlled to move downward stably relative to the first arm 21 along the sleeve 211 to achieve continuous material taking.

[0073] The structures of the first arm 21 and the second arm 22 can be in various forms as long as they can meet the requirements of normal operation and usage strength.

[0074] In one embodiment, the first arm 21 includes two parallel sleeves 211 and an intermediate rod 212 connecting and securing the two sleeves 211. The first arm 21 is generally a rectangular frame structure, with the two sleeves forming the two main beams of the rectangular frame. At least one intermediate rod 212 is connected between the two main beams to form the overall structure. The figure shows a specific embodiment in which three parallel intermediate rods 212 are disposed between the two sleeves 211.

[0075] Similarly, the second arm 22 can also be set as a rectangular frame structure. The second arm 22 includes two parallel longitudinal beams 221 and an intermediate component 222 connected and fixed between the two longitudinal beams 221. The two longitudinal beams 221 are respectively located inside the two sleeves 211, that is, the two longitudinal beams 221 have a matching sliding section, and the matching sliding section is set inside the sleeve 211. The intermediate component is connected to other positions of the longitudinal beams 221 except the matching sliding section. The intermediate component 222 forms the two longitudinal beams 221 into a stable whole. The number and arrangement position of the intermediate components 222 can be reasonably arranged according to the design requirements, as long as the use requirements are met. The figure shows a specific embodiment in which the upper and lower ends of the longitudinal beam 221 are provided with intermediate components 222.

[0076] In order to minimize the wear between the first arm 21 and the second arm 22, a wear-resistant structure may be provided at the relative moving contact position between the first arm 21 and the second arm 22. A specific setting method is given below.

[0077] In a specific embodiment, a wear-resistant sleeve 23 is provided inside the opening of the sleeve 211, and the outer wall of each wear-resistant sleeve 23 is provided with an insert extending outward. The inner wall of the sleeve 211 is provided with a socket 21a for mating with the insert, and the longitudinal beam 221 runs through the interior of each wear-resistant sleeve 23.

[0078] The number of the inserts 232 can be determined according to actual conditions, as long as the installation and positioning of the wear-resistant sleeve 23 and the sleeve 211 can be achieved.

[0079] The wear-resistant sleeve 23 can be a split structure, for example, the wear-resistant sleeve 23 can be formed by enclosing two or more wear-resistant sheets, and the longitudinal beam 221 runs through the space enclosed by each wear-resistant sheet. Of course, the wear-resistant sleeve 23 can also be a whole structure, and the whole structure of the wear-resistant sleeve can be quickly assembled.

[0080] The wear-resistant sleeve 23 can be directly formed from a wear-resistant material, or can be a component with a surface coated with a wear-resistant material.

[0081] Before inserting the second boom 22 into the sleeve 211 of the first boom 21, a wear-resistant sheet can be placed inside the sleeve 211 and then inserted into the socket 21a to align the wear-resistant sheet with the inner wall of the sleeve 211. After all the wear-resistant sheets are installed, the longitudinal beam 221 of the second boom 22 is inserted into the space enclosed by the wear-resistant sheets. When the second boom 22 moves up and down, it can contact the wear-resistant sheet, preventing wear on the first boom 21 and extending the service life of the system.

[0082] In a specific embodiment, the upper edge of the wear-resistant sleeve 23 is folded outward to form a flange 231, while the lower edge of the wear-resistant sleeve 23 is folded outward to form an insert 232. During installation, the flange 231 rests against the outer surface of the sleeve 211, while the insert 232 is positioned within the socket 21a. This ensures that the wear-resistant sleeve 23 is securely fixed to the sleeve 211 through the action of the flange 231 and the insert 232. This also facilitates removal and replacement of the fixing plate.

[0083] The above installation method is more suitable for the wear-resistant sleeve 23 with a split structure. As mentioned above, the wear-resistant sleeve 23 includes at least two wear-resistant plates, and the outer walls of the wear-resistant plates are provided with flanges and inserts. During assembly, each wear-resistant plate is installed one by one at the corresponding position of the sleeve 211.

[0084] Usually, it is difficult to remove materials from the sides and corners of the cabin. In order to remove the materials as much as possible, this article further improves the first arm 21 of the unloading equipment as follows.

[0085] Furthermore, in each of the above embodiments, the first arm 21 is hingedly connected to the main frame 1, with the hinge axis extending horizontally. In other words, the first arm 21 can swing vertically about the hinge axis to facilitate the removal of materials from different locations within the hold. The unloading device can also be equipped with a first adjustment component 4, which drives the first arm 21 to adjust the angle between the second arm 22 and the main frame 1.

[0086] The first adjusting component 4 can be an oil cylinder, a motor-gear, or a hoisting wire rope mechanism.

[0087] The first adjusting component 4 can realize automatic swing adjustment of the first arm 21. The first adjusting component 4 can be automatically controlled according to the material distribution information collected by the sensor component in the cabin, and of course can also be controlled according to the operator's experience.

[0088] And the first adjustment component 4 can lock the position of the second arm 22 relative to the first arm 21. In this way, the second arm 22 can be in its swing position to stably take materials, thereby increasing the stability of the system.

[0089] The first adjusting component 4 can be a telescopic cylinder, such as a hydraulic cylinder or a pneumatic cylinder. The first arm 21 can be provided with an articulated seat 214 connected to the telescopic cylinder.

[0090] In the above embodiments, the unloading equipment includes a power mechanism for providing power for the second arm 22 to move upward relative to the first arm 21; the power mechanism may include a telescopic cylinder 64, one end of the telescopic cylinder 64 is supported on the main frame 1, and the other end is connected to the second arm 22, or the power mechanism includes a winch-wire rope mechanism. The first adjusting component 4 can adjust the relative position of the second arm 22 relative to the first arm 21 according to parameters such as the distance between the second arm 22 and the material to be taken or the height of the material in the cabin, so as to realize or end material taking.

[0091] One end of the telescopic cylinder that drives the second arm 22 to move up and down can share a mounting base with the hinge axis of the first arm 21 and the main frame 1. That is to say, an articulated base 14 is fixed to the main frame 1, and the articulated base 14 is hinged to the first arm 21 through a pin 15. The articulated base 14 can be processed with an installation structure for installing the telescopic cylinder that drives the second arm 22 to move up and down.

[0092] This can reduce the number of components installed on the main frame 1, reduce the overall weight of the equipment, and meet the lightweight design requirements of the equipment.
