Description

Technical Field

[0001] The utility model belongs to the technical field of bulk cargo loading and unloading, and specifically relates to a portal crane accompanying hopper. Background Art

[0002] Portal cranes are large bulk cargo shore equipment used for loading and unloading ships at bulk cargo terminals. Generally, portal cranes are composed of main lifting mechanism, traveling mechanism, rotating mechanism, luffing mechanism, material system, etc. Portal crane bulk cargo loading and unloading is generally divided into three modes: rotating to the yard landing, bucket belt process, and bucket loading. Compared with the dock yard landing and bucket loading, the bucket belt process has higher loading and unloading efficiency and lower cost. Therefore, when the portal crane is loading and unloading bulk cargo, the bucket belt process operation mode is usually the first choice.

[0003] At present, the belt flow hoppers used for loading and unloading of gantry cranes at bulk cargo terminals are divided into two types: fixed belt flow hoppers in the yard and belt flow hoppers carried by the machine itself. The fixed belt flow hoppers in the yard cannot be moved randomly, and have great position limitations when loading and unloading cargo. The fixed belt flow hopper must be within the range of the gantry crane's rotation and amplitude variation. With the development trend of large-scale ships, the loading and unloading positions of gantry cranes are changeable, and the disadvantages of fixed belt flow hoppers are constantly emerging, which can no longer meet the current needs of efficient loading and unloading of bulk cargo on ships. The other is a form in which the gantry crane carries its own belt flow hopper. In this form, the gantry crane needs to be equipped with a belt flow hopper device, which makes the structure of the gantry crane complicated. At the same time, in order to meet the design requirements of the self-contained belt flow hopper, the overall height and weight of the gantry crane need to be increased, resulting in high manufacturing costs for the gantry crane and inconvenient repair and maintenance. When the tide rises or the cargo in the cabin is small, the hopper can only extend to a limited extent due to the high height of the hull, and the self-contained hopper cannot be used normally, resulting in reduced production or suspension of production.

[0004] Therefore, developing a gantry crane with a traveling hopper that has a convenient loading and unloading position, low manufacturing cost, strong versatility, and is not affected by the height of the hull is a technical problem that needs to be solved urgently. Utility Model Content

[0068] In some embodiments of the present application, a traveling bucket of a gantry crane is provided, which can move with the gantry crane and move with the help of the driving device of the gantry crane, thereby reducing the cost of the gantry crane; and because it moves with the gantry crane, it can facilitate the unloading of the cargo of the gantry crane.

[0069] In some embodiments of the present application, Figures 1 to 9 As shown, the portal crane traveling hopper includes a portal module 100 , a conical bucket body 200 , a feeding module 300 and a connecting module 400 .

[0070] like Figure 2 As shown, the portal module 100 is arranged below the conical bucket body 200. The portal module 100 is used to support the conical bucket body 200.

[0071] The gantry module 100 moves along the rail 510 of the gantry crane 500. The gantry module 100 is straddled above the conveyor belt 520.

[0072] The conical bucket 200 is used to receive the bulk cargo transferred by the portal crane 500.

[0073] like Figure 3 As shown, the feeding module 300 is connected to the outlet of the conical bucket 200. The feeding module 300 is used to transfer the bulk cargo in the conical bucket 200 to the conveyor belt 520.

[0074] The connection module 400 is used to connect the portal module 100 with the portal crane 500 .

[0075] The portal crane 500 drives the portal module 100 to move with the connecting module 400 .

[0076] The gantry module 100 includes a gantry body 110 , a moving assembly 120 and a connecting assembly.

[0077] The gantry body 110 includes a first support portion 111 and a second support portion 112. The first support portion 111 and the second support portion 112 are respectively arranged on both sides of the conveyor belt 520.

[0078] The moving assembly 120 includes two groups of moving rollers 121. The two groups of moving rollers 121 are respectively disposed at the lower ends of the first supporting portion 111 and the second supporting portion 112.

[0079] The connection assembly includes two sets of connection flanges 131 .

[0080] The two sets of connecting flanges 131 are respectively disposed at the lower ends of the first supporting portion 111 and the second supporting portion 112 .

[0081] The first support portion 111 and the second support portion 112 are detachably connected to the conical bucket body 200 via a connecting flange 131 .

[0082] The two groups of moving rollers 121 can roll along the tracks 510 respectively.

[0083] like Figure 1 As shown, the gantry body 110 is connected to the portal crane 500 through the connection module 400 . When the portal crane 500 moves along the track 510 , the gantry body 110 is driven to move along the track 510 through the connection module 400 .

[0084] The connection module 400 includes four connection rods 410 .

[0085] The four connecting rods 410 are connected to both sides of the portal crane 500 in groups of two.

[0086] Specifically, Figure 7 As shown, the connection module 400 includes a connection rod 410 , and ear plates 411 are formed at both ends of the connection rod 410 .

[0087] The connecting rod 410 is connected to the gantry body 110 and the portal crane 500 through the ear plate 411 .

[0088] like Figure 4 , Figure 5 , Figure 6 As shown, the conical bucket body 200 includes a bucket body 210 , a bucket support 220 and a bulkhead vibrator 230 .

[0089] The lower end of the hopper support 220 is connected to the portal module 100 .

[0090] Specifically, the lower end of the hopper bracket 220 is connected to the first support portion 111 and the second support portion 112 via a connecting flange 131 .

[0091] The bulkhead vibrator 230 is installed on the side wall of the conical bucket body 200. The vibration of the bulkhead vibrator 230 drives the conical bucket body 200 to vibrate, so that the bulk cargo in the conical bucket body 200 can be gradually output through the outlet end of the conical bucket body 200.

[0092] A discharge flow limiting plate 240 is provided at the outlet of the conical hopper body 200. The discharge flow limiting plate 240 is connected to the outlet of the hopper body 210, and is used to limit the discharge flow rate of the hopper body 210.

[0093] The discharge flow limiting plate 240 is slidably connected to the outer side wall of the hopper body 210 .

[0094] Specifically, a slideway 260 is provided on the outer side wall of the hopper body 210 , and the discharge flow limiting plate 240 can slide along the slideway, so as to control the flow rate of the discharge of the hopper.

[0095] In some embodiments of the present application, a feeding module 300 is provided at the outlet end of the conical bucket 200 .

[0096] The feeding module 300 includes a vibrating feeder 310 and a throwing box 320 .

[0097] The vibrating feeder 310 is disposed below the outlet of the hopper body 210 .

[0098] Specifically, the inlet end of the vibrating feeder 310 is disposed below the outlet of the hopper body 210 .

[0099] The height gradually decreases from the inlet end of the vibrating feeder 310 to the outlet section of the vibrating feeder 310. The vibrating feeder 310 is arranged inclined.

[0100] The outlet end of the vibrating feeder 310 is located above the throwing box 320. The bulk cargo flows through the hopper body 210, the vibrating feeder 310, the throwing box 320, and onto the conveying belt 520 located below.

[0101] In order to adjust the position of the bulk cargo falling from the throwing box 320 to the conveyor belt 520, when the conveyor belt 520 deviates, it is necessary to adjust the position of the bulk cargo output from the throwing box 320, so the feeding module 300 includes a seasoning component. The seasoning component is arranged at the outlet of the throwing box 320. The seasoning component is used to adjust the position of the bulk cargo falling from the outlet of the throwing box 320.

[0102] Specifically, Fig. 9 As shown, the seasoning assembly includes a vertical guide plate 321 and a driving component 322. The upper end of the vertical guide plate 321 is rotatably connected to the inner wall of the throwing box 320. The driving component 322 is used to drive the lower end of the vertical guide plate 321 to rotate relative to the upper end of the vertical guide plate 321. By rotating the lower end of the vertical guide plate 321, the position of the bulk cargo output from the lower end of the vertical guide plate 321 is adjusted, thereby adjusting the position where the bulk cargo falls to the conveyor belt 520.

[0103] In some embodiments of the present application, Figure 8 As shown, the conical bucket body 200 further includes a dustproof component 250. The dustproof component 250 is arranged around the upper edge of the hopper body 210 to prevent the diffusion of smoke and dust.

[0104] In some embodiments of the present application, a plurality of platforms 221 are arranged at intervals along the height direction of the hopper support 220. A first staircase 222 is connected between the plurality of platforms 221. The first staircase 222 is used for operators to climb from one platform 221 to another platform 221.

[0105] A guardrail 223 is formed around the platform 221 .

[0106] In some embodiments of the present application, the gantry module 100 further includes a second staircase 140 , and the second staircase 140 is extended along the height direction of the gantry body 110 .

[0107] The second staircase 140 is used for climbing along the height direction of the portal body 110 .

[0108] Since the gantry crane accompanying hopper moves with the gantry crane 500, the drive of the gantry crane 500 can be used as power, and the loading and unloading position is more convenient. Since the driving part is reduced, the cost can be saved.

[0109] Since the portal crane 500 and the portal crane traveling bucket can be connected via a connecting module, the portal crane traveling bucket has strong versatility and can be applied to a variety of portal cranes 500.

[0110] A portal crane traveling hopper can be arranged between two portal cranes 500 along the same track 510 for use in the front and rear portal cranes 500. In this case, further cost saving can be achieved.

[0111] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0112] The above is only a specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
