Description

Technical Field

[0001] The present invention belongs to the technical field of coal leveling, and particularly relates to a coal leveling device. Background Art

[0002] At present, there are two ways of coal leveling for railway freight coal-loading containers in China: manual raking and mechanical raking. For manual coal raking, the coal raking personnel need to use a coal rake to level the coal while loading the coal. This not only has a high labor intensity but also is extremely prone to safety hazards. Mechanical coal raking uses a similar fixed gantry device. The coal scraping plate is lowered, and the coal truck is pulled by a winch to move. The coal scraping plate levels the coal. The coal scraping plate has a fixed size and the width cannot be adjusted. Both of these two coal leveling methods work in a non-energized state and have a small adaptability and cannot be compatible with more vehicle types.

[0003] Therefore, it is necessary to propose a coal leveling device that can perform coal leveling operations in a high-voltage power grid area, and at the same time can meet the coal leveling operation requirements after coal loading in containers of different railway vehicle types, solve the influence of the high-voltage power grid area on loading, and enable the train to complete coal leveling operations during travel.

Detailed Description of the Embodiments

[0028] The present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0029] Embodiment:

[0030] Figure 1 The overall structural schematic diagram of a coal leveling device according to an embodiment of the present invention is shown; Figure 2 The structural schematic diagram of the cross beam of a coal leveling device according to an embodiment of the present invention is shown.

[0031] Combined with Figure 1-2 As shown, a coal leveling device for coal leveling operation of a moving railway coal loading truck includes a main column 1, an auxiliary column 2, a secondary column 3, and a cross beam 4;

[0032] Both the main column 1 and the auxiliary column 2 are located on one side of the track and are arranged in sequence along the direction parallel to the track. The secondary column 3 is arranged on the other side of the track and is arranged opposite to the main column 1;

[0033] A rotary drive mechanism 8 is provided at the top of the main column 1. One end of the cross beam 4 is connected to the rotary drive mechanism 8, and the other end of the cross beam 4 is a free end. The rotary drive mechanism 8 is used to drive the cross beam 4 to rotate around the main column 1 in the horizontal plane. A first C-shaped card slot 9 that cooperates with the free end of the cross beam 4 is provided at the top of the auxiliary column 2, and a second C-shaped card slot 10 that cooperates with the free end of the cross beam 4 is provided at the top of the secondary column 3. Both the first C-shaped card slot 9 and the second C-shaped card slot 10 have the same height as the cross beam 4. The opening direction of the first C-shaped card slot 9 is perpendicular to the track, and the opening direction of the second C-shaped card slot is parallel to the track. Both the first C-shaped card slot 9 and the second C-shaped card slot 10 are used to lock the free end of the cross beam 4;

[0034] A large flap 5 and a small flap 6 are provided at the bottom of the cross beam 4. The small flap 6 is arranged directly below the large flap 5. One end of the large flap 5 and one end of the small flap 6 are both hinged to the bottom of the cross beam 4. A first drive mechanism for driving the large flap 5 to flip up and down is provided on the cross beam 4, and a second drive mechanism for driving the small flap 6 to flip up and down is provided on the upper surface of the large flap 5.

[0035] Specifically, the auxiliary column 2 and the secondary column 3 are distributed around the main column 1 at a 90° angle with the main column 1 as the center. The cross beam 4 can rotate around the main column 1 through the rotary drive mechanism 8. When in the non-working state, the first U-shaped clamping groove 9 at the top of the auxiliary column 2 can receive and lock the free end of the cross beam 4. When in the working state, the second U-shaped clamping groove 10 at the top of the secondary column 3 can receive and lock the free end of the cross beam 4 that rotates from within the first U-shaped clamping groove 9.

[0036] Below the cross beam 4, there are a large tipping plate 5 and a small tipping plate 6 for leveling coal. When in the working state, according to the actual width and height of the carriage, the requirement of using the large tipping plate 5 or the small tipping plate 6 for scraping coal is selected. The large tipping plate 5 is driven to turn downward through the first drive mechanism or the small tipping plate 6 is driven to turn downward through the second drive mechanism to perform the coal leveling operation on the coal in the moving carriage, saving labor, improving work efficiency, and having a wide adaptability.

[0037] Since the current coal transportation method at the loading station tends to develop rapidly and diversely, different methods such as coal trucks, open wagons, and containers can be adopted. However, the box structures of each vehicle type are different. For example, the size difference between a 35-ton open-top container and a common open wagon is that the inner diameter of the container is about 500 mm narrower than that of the open wagon. When combining the two boxes on a flatbed truck, the overall height is about 1000 mm different from that of the open wagon. Setting two tipping plates, a large one and a small one, can meet the coal leveling requirements for different box widths and vehicle heights. In this embodiment, the maximum bearing capacity of the large tipping plate 5 is not greater than 1000 kg. When exceeding the maximum allowable value, the large tipping plate 5 can turn up by itself to prevent equipment damage and affect the normal operation of the train.

[0038] More specifically, the rotary drive mechanism 8 includes a rotary shaft 12. The rotary shaft 12 is arranged in the mounting seat 11 and is connected to the top of the main column 1. The mounting seat 11 is provided with a lightning protection device and a grounding device, which play a role in lightning protection.

[0039] As an alternative solution, a mounting groove is horizontally opened at the top of the main column 1. One end of the cross beam 4 is arranged in the mounting groove and is connected to the rotary drive mechanism 8.

[0040] Specifically, the rotary drive mechanism 8 drives the cross beam 4 to rotate horizontally in the mounting groove.

[0041] As an alternative solution, the inner upper and lower surfaces of the first U-shaped clamping groove 9 and the second U-shaped clamping groove 10 are respectively provided with grooves.

[0042] As an alternative solution, a locking mechanism is provided at the free end of the cross beam 4. The locking mechanism includes a protruding rod and a hydraulic cylinder. The hydraulic cylinder pushes the protruding rod to insert into the groove to lock the free end of the cross beam 4.

[0043] Specifically, the groove locks the extension rod of the free-end locking mechanism of the cross beam 4 in the first U-shaped card slot 9 or the second U-shaped card slot 10, preventing accidental movement or damage to the free end of the cross beam 4, effectively preventing misoperation, reducing damage to the device, and having safety and stability. The hydraulic cylinder at the free end of the cross beam 4 pushes the extension rod to be locked in the groove. The locking mechanism in this embodiment includes two telescopic rods that can extend upward and downward simultaneously. In other embodiments, it can also be a single telescopic rod that extends upward or downward alone. When in the working position, the large flap 5 and / or the small flap 6 can only be activated after the free end of the cross beam 4 is locked, and start to turn downward to work; when in the non-working position, the large flap 5 and / or the small flap 6 cannot be activated after the free end of the cross beam 4 is locked. This can effectively prevent misoperation, reduce damage to the device, and have the function of safety self-locking.

[0044] More specifically, when the free end of the cross beam 4 enters the second U-shaped card slot 10, it is in the working position, and when the free end of the cross beam 4 enters the first U-shaped card slot 9, it is in the non-working position.

[0045] As an alternative, the first driving mechanism includes a pair of first buffers 13 provided on one side of the cross beam 4, a pair of first levers 14 provided at the top of the cross beam 4, and a pair of first oil cylinders 15 provided on the upper surface of the large flap 5. One end of the first buffer 13 is hinged to one side of the cross beam 4, the other end of the first buffer 13 is hinged to one end of the first lever 14, one end of the first oil cylinder 15 is hinged to the upper surface of the large flap 5, and the other end of the first oil cylinder 15 is hinged to the other end of the first lever 14.

[0046] Specifically, the large flap 5 is driven by the telescopic movement of the extension rod of the first buffer 13 to pry the first lever 14. The prying of the first lever 14 drives the telescopic movement of the extension rod of the first oil cylinder 15. The telescopic movement of the extension rod of the first oil cylinder 15 drives the large flap 5 to turn upward and / or downward. When the large flap 5 turns downward, the small flap 6 on the lower surface of the large flap 5 also turns downward with the large flap 5. When the large flap 5 turns upward, the small flap 6 on the lower surface of the large flap 5 also turns upward with the large flap 5. When the large flap 5 turns upward and resets, the extension rod of the first buffer 13 retracts to drive the large flap 5 to turn upward and slowly reset.

[0047] The first buffer 13 is provided to prevent damage caused by the impact when the large flap 5 is quickly flipped up when the coal scraping resistance exceeds the maximum bearing pressure preset for the large flap 5 during the rapid movement of the carriage and / or the impact caused by the loss of control of the large flap 5 when power is cut off.

[0048] As an optional solution, the second driving mechanism includes a pair of second cylinders 16, a pair of second buffers 18 and a pair of second levers 17 arranged on the upper surface of the large flap 5. The large flap 5 is provided with a pair of through holes. One end of the second cylinder 16 passes through the through holes and is hinged to the upper surface of the large flap 5. The other end of the second cylinder 16 is hinged to one end of the second lever 17. One end of the second buffer 18 is hingedly connected to the upper surface of the small flap 6, and the other end of the second buffer 18 is hinged to the other end of the lever.

[0049] Specifically, the small flap 6 drives the second lever 17 to pry through the extension and retraction of the extension rod of the second oil cylinder 16, and the prying of the second lever 17 drives the extension rod of the second buffer 18 to extend and retract, and the extension rod of the second buffer 18 drives the small flap 6 to flip upward and / or downward. When the small flap 6 flips up and resets, the extension rod of the second buffer 18 retracts and drives the small flap 6 to flip upward and slowly reset.

[0050] The second buffer 18 is provided for when the coal scraping resistance exceeds the preset maximum bearing pressure of the small flap 6 when the car body is moving fast, the small flap 6 is quickly flipped up to cause impact and / or the small flap 6 is damaged by impact caused by control failure during power failure.

[0051] As an optional solution, the second lever 17 is an arc-shaped lever.

[0052] Specifically, in order to solve the installation space and reduce the load, the second lever 17 is adopted as follows Figure 2 The arc-shaped lever shown.

[0053] As an optional solution, the main column 1, the auxiliary column 2 and the secondary column 3 are all truss structures.

[0054] Specifically, the truss structure is a large-span lattice structure, which has the advantages of strong structure, easy assembly and maintenance, flexible structure arrangement, wide application range, etc. In other embodiments of the present invention, the main column 1, the auxiliary column 2 and the auxiliary column 3 can also be other forms of structures such as column type, which will not be described one by one here;

[0055] In this embodiment, the truss structure maximizes the coal scraping range of the large flap 5 and / or small flap 6 under the premise of meeting the limit requirements in the high-voltage power grid area of ​​the railway building, the height from the high-voltage power grid to the rail surface is 6550mm, and the minimum safety distance is not less than 1000mm; the maximum external dimensions of the main column 1, auxiliary column 2 and secondary column 3 of the truss structure in this embodiment are: height 5475mm, width 6600mm, length 6300mm.

[0056] As an optional solution, a top cover 7 and a top cover hoisting mechanism are provided directly above the rotary drive mechanism 8, and the top cover hoisting mechanism is used to hoist the top cover 7 during aerial operations.

[0057] Specifically, the setting of the top cover 7 and the top cover hoisting mechanism avoids the inconvenience of taking the end cover during high-altitude operations, reduces the risk of falling objects from high altitude, and ensures the personal safety of on-site workers.

[0058] As an alternative solution, the first oil cylinder 13, the second oil cylinder 16, the rotary drive mechanism 8, and the locking mechanism are respectively connected to the drive mechanism, the drive mechanism is connected to the control mechanism, and the first oil cylinder 13, the second oil cylinder 16, the rotary drive mechanism 8, the locking mechanism, the drive mechanism, and the control mechanism are all connected to the power supply.

[0059] Specifically, the first oil cylinder 13 and the second oil cylinder 16 are both hydraulic cylinders, the rotary drive mechanism 8 is driven by a motor to drive the gear shaft, the drive mechanism is a motor, and the control mechanism is a PLC. The hydraulic cylinder, the motor, the gear shaft, and the PLC are all prior arts and will not be described in detail here.

[0060] The specific working process is as follows: When starting the operation, the free end of the cross beam 4 is unlocked in the first C-shaped card slot 9 on the auxiliary column 2 by the hydraulic cylinder pushing the extension rod in the groove. The rotary drive mechanism 8 drives the cross beam 4 to rotate around the main column 1 in the horizontal plane. The free end of the cross beam 4 is screwed into the second C-shaped card slot 10 of the auxiliary column 3, and the extension rod is locked in the groove by the hydraulic cylinder. Multiple carriages are connected in sequence and travel on the track. According to the actual width and height of the carriage, the demand for using the large turning plate 5 or the small turning plate 6 for coal scraping is selected, and the large turning plate 5 and / or the small turning plate 6 are driven to turn downward by the first drive mechanism and / or the second drive mechanism to level the coal in the traveling carriage, saving manpower, improving work efficiency, and having a wide adaptability.

[0061] The above has described the embodiments of the present invention. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
