Description

Technical Field

[0001] The utility model relates to port barge transportation equipment, in particular to a sunken barge transportation chute structure. Background Art

[0002] As Figure 1 shown, the existing barge transportation system of the unloading terminal usually adopts a convex unloading chute 1, that is, the chute opening at the upper end of the unloading chute 1 is more than 1.5 m higher than the upper surface of the chute platform 2, and the barge conveyor belt 4 is inclined. The ore is passed through the main unloading chute 3 to the barge conveyor belt 4, and then the head chute 5 of the barge conveyor belt 4 is docked with the chute opening at the upper end of the convex unloading chute 1, and the ore is conveyed to the downstream barge conveyor belt 6 below the convex unloading chute 1 through the head chute 5. However, in the actual use process, it is found that the design of the convex unloading chute 1 has the following main defects:

[0003] 1. The head chute 5 of the barge conveyor belt 4 will form a climbing inclination angle a of 15-20°. Once the ore in the hopper collapses, it will cause the phenomenon of the inverted belt; 2. The rotary hinge shaft 7 at the tail of the barge conveyor belt 6 will be subjected to a large force, and abnormal conditions occur frequently (such as bearing damage, jamming, etc.), and the service life is short; 3. The convex receiving chute 1 will cause a large drop between the ore and the downstream barge conveyor belt 6 on the ground, the falling point is not easy to control, and the deviation fault occurs frequently.

[0004] In addition, there is no safety protection measure for the chute opening. When in the standby state or switching the unloading chute, the open chute opening is a serious safety hazard. Especially at night or in bad weather conditions, maintenance personnel may fall. If a protective net cover is installed and opened and closed manually, it is time-consuming and laborious. Therefore, how to make it open and close automatically to meet the requirements of barge transportation switching is also a problem to be solved. Content of the Utility Model

[0005] In order to solve the above problems of the prior art, the utility model provides a sunken barge transportation chute structure, which can effectively solve the problems of inverted belt and abnormal rotary hinge shaft, and can control the deviation abnormality caused by the downstream conveyor belt.

[0006] A sunken barge chute structure comprises a chute platform, a barge unloading chute arranged on the chute platform, a downstream barge conveyor belt arranged below the barge unloading chute, and a barge conveyor belt system for unloading the barge unloading chute. The barge conveyor belt system comprises a barge conveyor belt, a head chute and a driving mechanism thereof, the driving mechanism comprises a first track arranged on the chute platform, a driving wheel and a driving motor thereof for driving the barge conveyor belt and driving the head chute to move on the first track, the chute platform is horizontally arranged, the barge unloading chute is fixedly arranged at the lower part of the chute platform and its chute mouth is opened on the upper surface of the chute platform; the barge conveyor belt and its head chute are horizontally arranged on the chute platform, and the bottom slot of the head chute can be connected with the chute mouth of the barge unloading chute, and the tail of the barge conveyor belt is connected to the chute platform through a rotary hinge shaft.

[0022] The following is a further description of a sunken barge chute structure of the present invention. As Figure 2 shown, the sunken barge chute structure of the present invention includes a chute platform 2, a barge discharge chute 10 provided on the chute platform 2, a downstream barge conveyor belt 6 provided below the barge discharge chute 10, and a barge conveyor belt system for discharging the barge discharge chute 10. The number of barge discharge chutes 10 can be one or more than two, and the number of downstream barge conveyor belts 6 corresponds to the number of barge discharge chutes 10.

[0023] The barge conveyor system includes a barge conveyor belt 4, a head chute 5 and its driving mechanism. The driving mechanism includes a first track 9 provided on the chute platform 2, a driving wheel 8 for driving the barge conveyor belt 4 and driving the head chute 5 to move on the first track 9, and its driving motor. Different from the prior art, the chute platform 2 is horizontally arranged. The barge discharging chute 10 is fixedly arranged at the lower part of the chute platform 2, and its chute opening 11 is opened on the upper surface of the chute platform 2. The barge conveyor belt 4 and its head chute 5c are horizontally arranged on the chute platform 2, and the bottom chute opening of the head chute 5 can be docked with the chute opening 11 of the barge discharging chute 10. The tail of the barge conveyor belt 4 is connected to the chute platform 2 through a rotary hinge shaft 7. In this way, the barge discharging chute 10 adopts a sunken design, so that its chute opening 11 is flush with the chute platform 2, and the barge conveyor belt 4 and its head chute 5 have no climbing. This can effectively solve the problems of abnormal feeding belts and rotary hinge shafts 7. At the same time, the discharging height is reduced by about 1.5 meters, the deviation of the falling point is greatly controlled, and the abnormal deviation of the downstream conveyor belt caused is also greatly reduced.

[0024] Furthermore, to solve the safety hazard of the open chute opening 11 and the trouble of manually handling the protective cover, as Figures 3 - 4 shown, in the present invention, a movable protective net mechanism 20 is covered on the chute opening 11 of the barge discharging chute 10, and a push plate 51 for pushing the movable protective net mechanism 20 is also provided on the side of the head chute 5.

[0025] Specifically, in combination with Figures 5 - 6 shown, the movable protective net mechanism 20 includes a second track 23 arranged on the upper surface of the chute platform 2 on both sides of the chute opening 11, a protective net cover 21 covering the chute opening 11 and capable of sliding along the second track 23, and a pair of springs 27 for resetting the protective net cover 21. A rolling pulley set 22 cooperating with the second track 23 is provided on the protective net cover 21. One end of the spring 27 is arranged outside the second track 23 on the same side through a spring seat 25, and the other end is connected to the frame of the protective net cover 21 on the same side. The protective net cover 21 can adopt a rectangular structure or other shapes, and the height of the push plate 51 should be slightly higher than the chute opening 11 so as to be able to touch the end frame of the protective net cover 21, so that when the head chute 5 moves, the protective net cover 21 can be pushed open to expose the chute opening 11, realizing the docking of the head chute 5 and the chute opening 11 for discharging operations. When the protective net cover 21 is pushed open, the spring 27 is stretched. When the discharging is over, when the head chute 5 resets and waits for standby or needs to switch to other chute openings 11 for discharging, as the head chute 5 leaves, the protective net cover 21 automatically slides under the action of the spring 27 to cover the chute opening 11. The movable protective net mechanism 20 is applicable to a barge transportation system with one or two barge discharging chutes 10. If there are more than three barge discharging chutes 2, it is applicable to the barge discharging chutes 2 on both outsides.

[0026] Preferably, the second track 23 includes horizontal sections 23a horizontally arranged on both sides of the chute mouth 11 and a climbing section 23b located on the outer side of the chute mouth 11. The front end of the horizontal section 23a has a stop block 24. When the protective net cover 21 is pushed open, it will slide onto the climbing section 23b. In this way, when resetting, in addition to being affected by the spring 27, it can also be affected by its own gravity. Compared with the use of a single spring 27 for resetting, the resetting of the protective net cover 21 is more secure and less affected.

[0027] The horizontal section is also provided with an inductive proximity switch 28 for detecting the reset of the protective mesh cover 21. When in the standby state or switching state at the end of unloading, the inductive proximity switch 28 should sense that the chute mouth is covered by the protective mesh cover 21. If there is no signal, a corresponding alarm needs to be issued to check the cause of the fault in time.

[0028] However, those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
