Technical Field

[0001] The invention relates to the technical field of railway and port loading and unloading, and in particular to a material flow switching device for double buffer bin operations. Background Art

[0002] The loading station includes weighing system, unloading chute and gate device, hydraulic system, control system, vehicle number automatic recognition system, power supply and lighting system, scale calibration system, communication system, detection and monitoring system, water flushing device, system to prevent materials from freezing and sticking to the warehouse wall, air cannon system, air conditioning and ventilation system, dust removal system, fire fighting device, drainage device, maintenance and lifting equipment, return air system, steel structure and other auxiliary equipment and facilities.

[0003] During the loading process, the yard stacker or the dock direct take operation continuously takes materials and loads them into the buffer bin of the loading building through the conveyor. Then, according to the loading instructions, the buffer bin feeding gate is opened (the weighing bin loading gate is closed at this time), and the iron ore enters the weighing bin for automatic measurement. During the measurement process, the buffer bin feeding gate should have the function of adjusting the feeding amount. After the measurement work is completed, the buffer bin feeding gate is closed; when the vehicle enters the loading position, the weighing bin loading gate is immediately opened, and the dust removal device works at the same time. The iron ore is evenly loaded into the wagon, and this is carried out in sequence until the last wagon is loaded.

[0007] In the prior art, the loading station uses a belt line to supply double buffer bins, and the buffer bin operation switching process is completed by the reversible belt conveyor under the belt line. Frequent switching of the reversible belt conveyor will have a great impact on the reducer, and even affect the life of the equipment in serious cases. At the same time, when the reversible belt conveyor switches forward and reverse, the entire belt line needs to stop running, and the entire production line is affected, which has a great impact on the production efficiency of the loading station.

[0008] Therefore, it is necessary to study a material flow switching device for double buffer bin operations to solve the above problems or alleviate the impact of the above problems. Summary of the invention

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] like Figure 1 As shown, the material flow switching device for double buffer bin operation of the present invention may include a fixed belt conveyor 1 and a mobile belt conveyor 2. The fixed belt conveyor 1 and the mobile belt conveyor 2 are arranged in the loading building and are located between the pipe conveyor and the buffer bin. The fixed belt conveyor 1 is located below the outlet of the pipe conveyor, and the fixed belt conveyor 1 can receive the material transported by the pipe conveyor and guide it to the buffer bin on one side; the mobile belt conveyor 2 is located below the fixed belt conveyor 1, and the mobile belt conveyor 2 can move horizontally to below the diversion outlet of the fixed belt conveyor 1, and can receive the material flowing down from the fixed belt conveyor 1 and guide it to the buffer bin on the other side.

[0036] Specifically, during loading operations, materials are transported to the fixed belt conveyor 1 through a belt conveyor, and flow into one of the double buffer bins from its diversion outlet along the diversion direction of the fixed belt conveyor 1; when the material flow needs to be switched, the mobile belt conveyor 2 is driven to move horizontally below the diversion outlet of the fixed belt conveyor 1, so that the mobile belt conveyor 2 can fully receive the materials flowing down from the fixed belt conveyor 1, and the materials change their movement direction and flow into the other buffer bin from its diversion outlet along the diversion direction of the mobile belt conveyor 2.

[0037] In general, the material flow switching device for double buffer bin operation of the present invention can guide the material to the corresponding bin of the double buffer bin through the cooperation of the mobile belt conveyor 2 and the fixed belt conveyor 1. In this way, the reversible belt conveyor can be replaced. When the material flow is switched by the mobile belt conveyor 2, the pipe belt conveyor can still work normally, which solves the problem that the entire belt line needs to stop working when changing the running direction of the reversible belt conveyor to switch the operation buffer bin, avoids the problems of reduced work efficiency and reduced equipment life caused by switching the running direction of the reversible belt conveyor, and can effectively improve the loading efficiency and equipment life.

[0038] It should be noted that, in the operation process of the existing reversible belt conveyor, the system can be upgraded by using the reversible belt conveyor as a fixed belt and adding a mobile belt conveyor 2 thereunder to form the material flow switching device for double buffer bin operation of the present invention.

[0039] like Figure 2 As shown, in one example, a support frame 3 is provided at the bottom of the mobile belt conveyor 2, and the mobile belt conveyor 2 can move horizontally on a track 4 provided on the loading building through the support frame 3.

[0040] Specifically, the mobile belt conveyor 2 is installed on the support frame 3, the support frame 3 forms an overall support for the mobile belt conveyor 2, and the track 4 is horizontally fixed on the fixed plate 21 in the loading building. The support frame 3 can drive the mobile belt conveyor 2 to move along the track 4 as a whole to realize the translation of the mobile belt conveyor 2.

[0041] like Figure 2 As shown, in one example, a plurality of sets of track wheels 5 are provided at the bottom of the support frame 3 , and the support frame 3 moves on the track 4 via the track wheels 5 .

[0042] Specifically, a plurality of sets of track wheels 5 are evenly distributed at the bottom of the support frame 3 , which can form a stable support for the support frame 3 and the mobile belt conveyor 2 on the support frame 3 . The track wheels 5 roll on the track 4 to realize the movement of the support frame 3 .

[0043] like Figure 2 As shown, in one example, a driving gear 6 is provided on the track 4 , and a guide rail 7 meshing with the driving gear 6 is provided at the bottom of the support frame 3 .

[0044] Specifically, the driving gear 6 is fixedly arranged on the track 4. The guide rail 7 can be configured as a toothed structure arranged in the horizontal direction, or can also be a chain structure. The support frame 3 is driven by the driving gear 6 to move in the horizontal direction through the meshing of the guide rail 7 and the driving gear 6.

[0045] Furthermore, the driving gear 6 is drivingly connected to the output end of the driving motor 8. The driving motor 8 provides power for the rotation of the driving gear 6, and the driving motor 8 changes the translation direction of the mobile belt conveyor 2 by electrically controlling the forward and reverse rotation of the driving gear 6.

[0046] like Figure 1 As shown, in one example, the fixed belt conveyor 1 and the mobile belt conveyor 2 both include a frame 9, a driving roller 10 and a redirecting roller 11, the driving roller 10 and the redirecting roller 11 are respectively arranged at both ends of the frame 9, and the axes of the driving roller 10 and the redirecting roller 11 are parallel. The fixed belt conveyor 1 and the mobile belt conveyor 2 also include a conveyor belt 12 in an endless ring structure, and the conveyor belt 12 is sleeved on the driving roller 10 and the redirecting roller 11.

[0047] Specifically, the driving roller 10 is arranged at one end of the frame 9, the redirecting roller 11 is arranged at the other end of the frame 9, the conveyor belt 12 is sleeved on the driving roller 10 and the redirecting roller 11, and a roller motor 13 connected to the driving roller 10 is fixed on the frame 9. The driving roller 10 is driven by the roller motor 13 to rotate, and the driving roller 10 drives the conveyor belt 12 to move along the diversion direction, so that the conveyor belt 12 transports the material to the diversion outlet, and the material flows downward from the diversion outlet after reaching the diversion outlet, and the conveyor belt 12 passes through the redirecting roller 11 and then turns back to the driving roller 10 to form a cycle.

[0048] like Figure 5 and Figure 6 As shown, in one example, the material flow switching device also includes a material guiding mechanism, which includes a material guiding plate 15, which is obliquely arranged between the fixed belt conveyor 1 and the mobile belt conveyor 2, and the material guiding plate 15 can guide the material flowing down from the fixed belt conveyor 1 to the mobile belt conveyor 2.

[0049] Specifically, there is a certain height difference between the fixed belt conveyor 1 and the mobile belt conveyor 2. If the material flowing out of the fixed belt conveyor 1 falls directly on the mobile belt conveyor 2, it will scatter, causing part of the material to fall out of the mobile belt conveyor 2. An inclined material guide plate 15 is arranged between the fixed belt conveyor 1 and the mobile belt conveyor 2, so that the material flowing out of the fixed belt conveyor 1 is buffered on the material guide plate 15, and can flow to the mobile belt conveyor 2 along the inclined direction of the material guide plate 15, so as to avoid the material from scattering, and facilitate the mobile belt conveyor 2 to effectively receive the material flowing down from the fixed belt conveyor 1.

[0050] like Figure 5 and Figure 6 As shown, in one example, the material guiding mechanism also includes a hydraulic cylinder 16 and a connecting rod assembly. The hydraulic cylinder 16 is installed on a fixed plate 21 in the loading building. The telescopic rod 17 of the hydraulic cylinder 16 is connected to the material guiding plate 15 through the connecting rod assembly. The hydraulic cylinder 16 can be telescoped in the horizontal direction to adjust the horizontal movement of the material guiding plate 15.

[0051] Specifically, the hydraulic cylinder 16 is installed on the fixed plate 21 in the loading building, and can drive the telescopic rod 17 to extend and retract in the horizontal direction. The telescopic rod 17 supports the guide plate 15 through the connecting rod assembly. In this way, when it is necessary to switch the buffer bin where the materials flow in, the hydraulic cylinder 16 will be started to drive the guide plate 15 to move synchronously with the mobile belt conveyor 2 to the bottom of the diversion outlet of the fixed belt conveyor 1, so as to buffer and guide the materials flowing down from the fixed belt conveyor 1 received by the mobile belt conveyor 2.

[0052] Furthermore, the connecting rod assembly includes a first support rod 18 and a second support rod 19 connected between the guide plate 15 and the telescopic rod 17, and the length of the first support rod 18 is smaller than that of the second support rod 19. In this way, the first support rod 18 is connected to the inclined lower end of the guide plate 15, and the second support rod 19 is connected to the inclined upper end of the guide plate 15, so that the guide plate 15 is inclined toward the mobile belt conveyor 2. In addition, both the first support rod 18 and the second support rod 19 can be designed as telescopically adjustable support rods. When used, the length ratio of the first support rod 18 to the second support rod 19 can be adjusted according to actual conditions to adjust the inclination angle of the guide plate 15.

[0053] Furthermore, the connecting rod assembly may further include two third support rods 20 arranged in parallel, and the two ends of the third support rod 20 are respectively hinged to the telescopic rod 17 and the fixed plate 21. The third support rod 20 swings a corresponding angle as the telescopic rod 17 is adjusted horizontally, and at the same time, after the telescopic rod 17 is adjusted and positioned, it can support the telescopic rod 17 and the material guide plate 15 above it.

[0054] It should be noted that the front and rear sides of the guide plate 15 (i.e. Figure 5 and Figure 6 A set of hydraulic cylinders 16 and connecting rod assemblies are provided (front and back of the viewing angle), that is, the two sets of hydraulic cylinders 16 and connecting rod assemblies cooperate together to support and adjust the movement of the guide plate 15 accordingly.

[0055] like Figure 4 and Figure 6 As shown, in one example, the mobile belt conveyor 2 has an opposite flow direction to the fixed belt conveyor 1. The fixed belt conveyor 1 directs the material to a buffer bin on one side, while the mobile belt conveyor 2 receives the material from the fixed belt conveyor 1 and directs it to a buffer bin on the other side (in the opposite direction).

[0056] like Figure 1 and Figure 2 As shown, in one example, the outlet ends of the fixed belt conveyor 1 and the mobile belt conveyor 2 are both provided with a material guide chute 14. The material guide chute 14 can prevent the material from being scattered and effectively guide the material to the predetermined target.

[0057] In one example, the material flow switching device further includes a control system (not shown in the drawings), which can control the movement of the mobile belt conveyor 2, control the drive of the hydraulic cylinder 16, and control the start and stop of the fixed belt conveyor 1 and the mobile belt conveyor 2. Specifically, the control system may include three control systems: local control, automatic control, and driver manual control, to ensure the reliability of the operation of the material flow switching device for double buffer bin operations.

[0058] In order to better understand the above embodiment, the working process of the material flow switching device of the present invention is further described below in conjunction with the accompanying drawings.

[0059] When assembling the material flow switching device, it is only necessary to install the mobile belt conveyor 2 directly below the fixed belt conveyor 1 (reversible belt conveyor). The mobile belt conveyor 2 is installed on the support frame 3 through the frame 9, and then the support frame 3 is placed on the track 4. The driving gear 6 fixed on the track 4 interacts with the guide rail 7 at the bottom of the support frame 3, so that the mobile belt conveyor 2 can be translated left and right. At the same time, the guide plate 15 is installed between the fixed belt conveyor 1 and the mobile belt conveyor 2 through the connecting rod assembly and the hydraulic cylinder 16.

[0060] When the right buffer bin operation is required (such as Figure 4 and Figure 6 ), the material flows through the belt conveyor and then enters the fixed belt conveyor 1, and then directly enters the right buffer bin through the guide trough 14 of the diversion outlet of the fixed belt conveyor 1. When it is necessary to switch the material flow to the left buffer bin, the control system sends a control signal to the drive motor 8, driving the mobile belt conveyor 2 to translate to the right, and after reaching the predetermined position below the diversion outlet of the fixed belt conveyor 1 to trigger the limit device, the electric latch is opened to fix the mobile belt conveyor 2; at the same time, the control system sends a control signal to the hydraulic cylinder 16, driving the guide plate 15 and the mobile belt conveyor 2 to move synchronously to the bottom of the diversion outlet of the fixed belt conveyor 1; in this way, the material flowing out of the guide trough 14 of the diversion outlet of the fixed belt conveyor 1 is buffered and guided by the guide plate 15, and the material enters the mobile belt conveyor 2, and then enters the left buffer bin through the guide trough 14 of the diversion outlet of the mobile belt conveyor 2, thereby realizing two-way diversion. The material flow switching device of the present invention is used for the material flow direction when the double buffer bin is operated. Figure 4 or Figure 6 As shown, in the prior art, when a reversible belt conveyor is used for double buffer bin operation, the material flow direction is as follows Figure 3 shown.

[0061] Compared with the prior art, the material flow switching device for double buffer bin operation of the present invention has the following technical effects:

[0062] The present invention can solve the problem that during the operation of the double buffer bins at the loading station, when the running direction of the reversible belt conveyor is changed to switch the operation buffer bin, the entire belt line needs to stop operating; the process switching of the present invention can realize automatic control, reduce the labor intensity of personnel, and greatly improve the operation efficiency of the loading station. It is expected that the efficiency of each ship from unloading to loading operations will be improved by more than 20%; the present invention can avoid the influence of frequent forward and reverse rotation of the belt conveyor on the equipment, and increase the service life of the equipment by more than 30%; the process switching setting of the present invention has three sets of control system redundancy: local control, automatic control, and driver manual control, which ensures the reliability of process switching.

[0063] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
