Description

Technical Field

[0001] This application relates to the field of bottom-opening door technology for hopper cars, and particularly to a bottom-opening door device, a bottom-opening door system, and a hopper car transport line. Background Technology

[0002] A bottom-opening hopper car is a type of railway freight car with a large hopper compartment. The hopper compartment gradually narrows from top to bottom, and the lower end is sealed by a door to block the outlet for goods. It is used to load bulk goods such as grain and coal. A bottom-opening hopper car transport line consists of bottom-opening hopper cars and a collision device, which controls the opening and closing of the bottom door.

[0003] However, the unloading point of the transport line is set on the railway. That is, when unloading, the hopper car does not leave the track. After the door is opened, the goods are automatically unloaded by their own weight. After unloading is completed, the door is closed and the hopper car leaves the unloading point, completing one transport operation.

[0004] Currently, coal hopper cars with self-locking transverse bottom doors that have exceeded dead center limits need to be promoted and used in existing power plants. However, power plants only have relatively primitive coal unloading pits, suitable for unloading operations of open wagons or manually opened hopper cars. They are not yet able to unload coal hopper cars with self-locking transverse bottom doors that have exceeded dead center limits, cannot adapt to the unloading environment of coal unloading pits, and affect the unloading devices of existing hopper cars used by power plants.

[0005] The coal hopper car unloading method that adopts the principle of over-dead-point self-locking transverse bottom door opening and closing mechanism all involve the vehicle moving and actively touching the fixed ground contact device to open the bottom door. When the vehicle is unloading, it is required that the vehicle has kinetic energy and requires a large amount of work to modify, which has a certain impact on the original vehicle unloading. At the same time, due to the setting of the ground contact device, the unloading is uneven, which leads to the inability to make full use of the coal storage space in the unloading pit.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

Figure 2 This application provides a front view of the bottom door opening device in its first operating state according to an embodiment of the present application. Figure 3 This application provides a front view of the bottom door opening device in its second operating state according to an embodiment of the present application. Figure 4 A partial structural schematic diagram of the hopper car 504 transport line is provided for the embodiments of this application.

[0035] It should be noted that, Figure 2 This is a front view of the bottom door opening device in its first operating state, as provided in this application embodiment, that is, a structural schematic diagram when the door opening member 100 is in the first position. Figure 3 This is a front view of the bottom door opening device in the second operating state according to an embodiment of this application, that is, a structural schematic diagram when the door opening member 100 is in the second position.

[0036] like Figure 1 , Figure 4As shown, in one aspect, this application provides a bottom door opening device, which includes an opening component 100 and a moving component 200, wherein:

[0037] The door opening component 100 has a first inclined surface 101. After the door opening component 100 is assembled, the first inclined surface 101 on the door opening component 100 is inclined relative to the unloading operation surface of the hopper car 504. That is to say, the first inclined surface 101 has two ends with different heights relative to the unloading operation surface of the hopper car 504.

[0038] The movable component 200 is supported under the door opening member 100 and is used to move the door opening member 100. The movable component 200 is configured such that, during the movement of the door opening member 100, the door opening member 100 can approach the door opening arm 501 of the hopper cart, so that after the first inclined surface 101 raises the door opening arm 501, the door opening arm 501 pushes the bottom door of the hopper cart 504 to the open state. The movable component 200 can move on the unloading surface of the hopper cart 504, and during the movement, it moves the door opening member 100 together with it. When the door opening component 100 moves, the first inclined surface 101 on the door opening component 100 is close to the door opening arm 501 on the bottom door of the hopper car 504. Since the first inclined surface 101 has two ends with different heights relative to the unloading operation surface of the hopper car 504, when the door opening is continuously moving, the door opening arm 501 on the relatively stationary hopper car 504 can move from the lower side of the first inclined surface 101 to the higher side through the relative force generated by the movement of the door opening component 100, thereby forming a lifting of the door opening arm 501. Then, through the lifting action of the door opening arm 501, the bottom door of the hopper car 504 is opened in conjunction.

[0039] It should be noted that the first inclined plane 101 is set so that different positions on the first inclined plane 101 have different distances from the unloading operation surface of the hopper car 504. In actual operation, the first inclined plane 101 can be set as a plane. A smooth first inclined plane 101 setting can obtain a more linear driving effect. That is to say, when the first inclined plane 101 is a plane and the moving speed of the moving component 200 is uniform, the door opening arm 501 can maintain a relative transport movement state on the first inclined plane 101.

[0040] The first inclined surface 101 can also be configured as a curved surface, and the first inclined surface 101 of the curved surface can include arc segments with different inclination degrees. Under the premise that the moving speed of the moving component 200 is uniform, it makes it easier for the door opening arm 501 to be lifted at the beginning. That is to say, the door opening component 100 was originally in the closed position of the bottom door. It takes a certain force to drive the door opening component 100 to be lifted. In the process of the moving component 200 generating force during relative movement, the moving resistance of the moving component 200 is reduced by the arc segment with a smaller inclination degree. At this time, the height to which the door opening component 100 is lifted is small, and the resistance of the displacement of the moving component 200 is small. After the door opening arm 501 is lifted to a certain height, the force required for the door opening arm 501 to be lifted further is reduced. At this time, the first inclined surface 101 can adopt an arc segment with a larger inclination degree to lift the door opening arm 501 more quickly, so as to improve the lifting efficiency of the door opening arm 501, while reducing the resistance of the moving component 200 during movement and improving the lifting reliability and stability.

[0041] The working principle of the bottom door opening device in this application is as follows: In an optional embodiment, the bottom door opening device includes an opening member 100 and a moving component 200. The opening member 100 is provided with a first inclined surface 101. The moving component 200 is supported under the opening member 100 and is used to drive the opening member 100 to move closer to the opening arm 501. The moving component 200 is configured such that when the moving component 200 drives the opening member 100 to move, the opening member 100 moves closer to the opening arm 501, so that the first inclined surface 101 raises the opening arm 501 to the bottom door open state. When it is necessary to perform the door opening operation, the moving component 200 drives the opening member 100 to move on one side of the hopper car 504, and the first inclined surface 101 on the opening member 100 touches the bottom door of the hopper car 504. The door opening arm 501, driven by the continuous displacement of the moving component 200, is lifted under the guidance of the first inclined plane 101, causing the bottom door of the hopper car 504 to open in conjunction. The entire process does not require the vehicle to move actively, and the bottom door of the hopper car 504 in different positions can be flexibly opened. On the one hand, it saves the hopper car 504 from actively moving to collide and open the door. On the other hand, the door opening position can be reasonably arranged to ensure the uniformity of unloading, improve unloading efficiency, avoid secondary operations in the unloading area, and make fuller use of the coal storage space in the unloading pit. Moreover, the bottom door opening device can be arranged more flexibly and with less modification on the existing unloading ground and used in conjunction with the existing hopper car 504. It has strong applicability and low cost.

[0042] like Figure 2 , Figure 3As shown, in an optional embodiment, the door opening member 100 has a first position and a second position. When the door opening member 100 is in the first position, the door opening member 100 can extend under the door opening arm 501 under the drive of the moving component 200. When the door opening member 100 is in the second position, the door opening member 100 is away from the door opening arm 501.

[0043] The door opening component 100 serves as a structural assembly for lifting the door opening arm 501. The door opening component 100 has a first position and a second position, and can switch between these positions as needed. When the door opening component 100 is in the first position, it extends under the door opening arm 501 under the drive of the moving component 200. In this state, the door opening component 100, driven by the moving component 200, lifts the door opening arm 501, thereby completing the door opening operation. When the door opening component 100 is in the second position, the door opening component 100... When the door opening arm 501 is far away from the door opening component 100, the door opening component 100, driven by the moving component 200, always remains far away from the door opening arm 501. This facilitates flexible movement during non-door opening operations or allows for avoidance of the door opening arm 501 and the hopper 504. Within the work area, the reliability of the door opening component 100 is improved by using the first and second positions for both door opening and non-door opening purposes. At the same time, it reduces the operational difficulty of the moving component 200, avoids the overall displacement of the moving component 200 to achieve the operational and avoidance effects, and reduces the difficulty and complexity of equipment control.

[0044] In an optional embodiment, a push-pull portion 301 is provided between the moving component 200 and the door opening component 100, and the push-pull portion 301 drives the door opening component 100 to reciprocate between the first position and the second position.

[0045] The push-pull part 301 is located between the moving component 200 and the door opening component 100, and serves as a power output component. When the door needs to be opened, the push-pull part 301 can drive the door opening component 100 to move to the first position. At this time, the door opening component 100 located in the first position can push the door opening arm 501 to move under the action of the moving component 200. When performing operations other than opening the door, the push part drives the door opening component 100 to move from the first position to the second position, thereby achieving a more stable and reliable operation. Moreover, under the premise of long-term continuous and repetitive operation, efficiency can be improved.

[0046] It should be noted that the specific configuration of the push-pull part 301 can be adjusted and replaced according to the working environment and requirements. The push-pull part 301 can be configured as an electric push rod or a cylinder, etc., which will not be further elaborated or explained here.

[0047] In an optional embodiment, a plurality of traction portions 302 are provided between the moving component 200 and the side wall of the door opening member 100. The traction portions 302 are respectively hinged to the moving component 200 and the door opening member 100 to restrict the rotation of the door opening member 100.

[0048] During the process of the pusher driving the door opening member 100 to move between the first position and the second position, in order to further improve the stability of the position of the door opening member 100 during this process, multiple traction units 302 can be connected to the door opening member 100 respectively and restrain the door opening member 100. Combined with the drive of the pusher driving the door opening member 100, the door opening member 100 is simultaneously subjected to the force of the pusher and the traction units 302, thereby maintaining a relatively stable switching between the first position and the second position. That is to say, during the process of the pusher driving the door opening member 100 to move between the first position and the second position, the door opening member 100 itself is prone to rotate at a certain angle around the connection point between the pusher and the door opening member 100 as the rotation center under the action of gravity. At this time, it is not conducive to the relative positional matching accuracy between the door opening member 100 and the door opening arm 501, and it is also easy for the door opening member 100 to stay in the area outside the first position and the second position. The multiple traction units 302 are provided to achieve traction on the door opening member 100 in another direction, thereby improving the stability and reliability of the door opening member 100.

[0049] In an optional embodiment, the moving component 200 is further provided with a plurality of support portions 303, which are configured such that when the door opening member 100 is in the first position, the support portion 303 supports the lower part of the door opening member 100 to limit the door opening member 100 from continuing to descend.

[0050] As the pusher drives the door opening member 100 to move between the first and second positions, multiple traction units 302 connect to the door opening member 100 and restrain it. Combined with the pusher's drive, the door opening member 100 is simultaneously subjected to the forces of the pusher and traction units 302, thus maintaining a relatively stable transition between the first and second positions. When the door opening member 100 is in the first position, it needs to abut against the door opening arm 501 until the door opening arm 501 is lifted to the opening position. During this process, the interaction force between the door opening member 100 and the door opening arm 501 ensures the door opening member 100 remains highly stable. The door opening arm 501 can only be raised when the door opening component 100 and the door opening arm 501 are in mutual contact. In order to maintain the stability of the door opening component 100 when it is in mutual contact with the door opening arm 501, and to keep the distance between the door opening component 100 and the unloading operation surface of the hopper car 504 unchanged in this state, multiple support parts 303 are provided and set at the lower part of the door opening component 100. When the door opening component 100 moves to the first position, it also falls on multiple support parts 303. At this time, the support parts provide a stable and reliable support foundation. When the door opening component 100 is subjected to a force in the direction of the unloading operation surface of the hopper car 504, it can be stably maintained at the height of the first position, and then the door opening arm 501 is guided to complete the lifting action through the first inclined surface 101.

[0051] In an optional embodiment, the bottom door opening device further includes a bracket 304, which is detachably fixed to the movable component 200. The push-pull part 301, the traction part 302, and the support part 303 are respectively provided on the bracket 304.

[0052] The push-pull part 301, the traction part 302, and the support part 303 can be arranged on the bracket 304. Correspondingly, the door opening part 100 is arranged on the bracket 304 via the push-pull part 301, the traction part 302, and the support part 303. By operating the rack, the entire assembly and disassembly of the push-pull part 301, the traction part 302, the support part 303, and the door opening part 100 on the rack can be completed, improving the convenience of operation. It should also be noted that the length and angle settings of the push-pull part 301 and the traction part 302 are... They are arranged in a coordinated manner, corresponding to the first and second positions of the door opening component 100. In order to avoid the need to reset and adjust the push-pull part 301, traction part 302 and support part 303 every time, the bracket 304 is set to directly and once to position and assemble the push-pull part 301, traction part 302 and support part 303, which greatly reduces the labor intensity of operation, improves the work efficiency, and the assembly accuracy between related components is higher. The linkage effect between the door opening component 100 and the door opening arm 501 is better, and the operation is more stable and reliable.

[0053] In an optional embodiment, the moving component 200 includes a frame 201, a drive unit 202, and an execution unit 203. The door opening component 100, the drive unit 202, and the execution unit 203 are respectively disposed on the frame 201. The output end of the drive unit 202 is connected to the execution unit 203 to drive the execution unit 203 to move the frame 201.

[0054] The frame 201 serves as the assembly base, facilitating the support of the door opening component 100 and maintaining the relative positional relationship between the drive unit 202 and the actuator 203. After assembly, the drive unit 202 can maintain stable power output and drive itself to move the frame 201. In actual operation, the frame 201 moves to the unloading surface of the hopper car 504, and under the working drive of the drive unit 202, the actuator drives the frame 201 to move on the unloading surface of the hopper car 504. The door opening component 100 on the frame 201 moves synchronously with the frame 201, touches and lifts the door opening arm 501, and completes the operation.

[0055] It should be noted that in actual implementation, the drive unit 202 can be a drive motor, the execution unit 203 can be a drive wheel, and correspondingly, driven wheels can be set, which can reduce the number of drive motors and improve the stability of the frame 201.

[0056] It should be noted that since the unloading operation surface of the hopper car 504 is mostly paved with grating to facilitate the material falling into the pit, in order to maintain the stability of the movement of the actuator 203 on the unloading operation surface of the hopper car 504, tracks can be installed on the actuator 203 to improve the reliability during the movement process. When facing the grating area in the unloading operation surface of the hopper car 504, it can move more stably along the target direction at the target speed.

[0057] In an optional embodiment, a function control system can be arranged on the frame 201. The function control system is connected to the push-pull part 301 and the drive part 202, provides the electrical energy required for the push-pull part 301 and the drive part 202 to work, and controls the working status of the push-pull part 301 and the drive part 202.

[0058] In an optional embodiment, the frame 201 is further provided with multiple sets of load-bearing wheels 204, which are spaced apart on both sides of the frame 201.

[0059] The frame 201 is also equipped with load-bearing wheels 204, which reduces the support of the actuator 203 on the overall weight of the frame 201, improves the driving effect of the actuator 203, maintains the relative stability of the frame 201 as a whole, and allows the frame 201 and the door opening component 100 on the frame 201 to achieve a more stable operating state when performing door opening operations.

[0060] In an optional embodiment, the moving component 200 is provided with a rotatable guide portion 400 for cooperating with the grille and restricting the moving direction of the moving component 200.

[0061] The frame 201 moves to the unloading surface of the hopper car 504, and under the working drive of the drive unit 202, the actuator drives the frame 201 to move on the unloading surface of the hopper car 504. However, since the unloading surface of the hopper car 504 is mostly covered by a grid to facilitate the falling of materials into the pit, the grid area forms multiple through holes for materials to fall. In order to further maintain the accuracy of the moving path of the moving component 200, that is, to avoid the moving component 200 from deviating during the movement, it would cause the upper door arm 501 of the hopper car 504 to be unstablely raised to the open position, affecting the operation. During normal operation, the guide part 400 is set on the moving component 200. As the moving component 200 moves, the guide part 400 rotates relative to the grid to cooperate with it. The relative positional relationship between the guide part 400 and the moving component 200 is fixed. Through the cooperation between the guide part 400 and the grid, the guide part 400 constrains the moving direction of the moving component 200, thereby correcting the deviation of the moving component 200 during its movement, keeping the moving component 200 moving in the set direction, maintaining the moving accuracy, and allowing the multiple door arms 501 on the hopper car 504 to be opened sequentially, resulting in greater stability.

[0062] In an optional embodiment, the guide portion 400 is provided with a first slot 401 and a plurality of second slots 402. The first slot 401 and the second slots 402 are configured such that when the guide portion 400 rotates, the first slot 401 can continuously accommodate the longitudinal ribs 502 of the grid, and the second slots 402 can sequentially accommodate and flip over the transverse ribs 503 of the grid.

[0063] The guide portion 400 has a first slot 401 and a second slot 402. The first slot 401 engages with the longitudinal rib 502 of the grid, and the second slot 402 engages with the transverse rib 503 of the grid. It should be noted that the longitudinal rib 502 extends along the moving direction of the moving component 200, and the transverse rib 503 intersects with it. After the moving component 200 is placed on the grid, the first slot 401 on the guide portion 400 engages with the longitudinal rib 502. As the moving component 200 moves, the longitudinal rib 502 remains extended into the first slot 401. The guide portion 400 engages with the longitudinal rib 502 through the first slot 401. The positional relationship between the two forms a directional constraint on the movement of the moving component 200. At the same time, as the moving component 200 moves, the multiple second slots 402 on the guide part 400 engage the grid cross ribs 503 during rotation and flip over the grid cross ribs 503 during the rotation of the guide part 400. During continuous rotation, as the first slot 401 guides the guide part 400 to continue rotating, the next second slot 402 will engage the next grid cross rib 503. During continuous operation, the guide part 400 flips over multiple grid cross ribs 503, which not only improves the operational stability of the moving component 200 and the guide part 400, but also maintains the movement accuracy and movement rhythm.

[0064] In an optional embodiment, the guide portion 400 is elliptical and detachable from the moving component 200 to move closer to or further away from the grille. The elliptical and detachable configuration of the guide portion 400 allows it to move closer to or further away from the unloading surface of the hopper car 504 through lifting and lowering operations. In the non-operating state, the moving component 200 rises and moves away from the unloading surface of the hopper car 504, thereby separating the guide portion 400 from the grille horizontal ribs 503 and the grille vertical ribs 502 respectively. When the door opening operation is required, the moving component 200 descends and moves closer to the unloading surface of the hopper car 504 until the first slot 401 and the second slot 402 on the guide portion 400 engage with the grille vertical ribs 502 and the grille horizontal ribs 503 respectively, thereby providing stable guidance during the door opening operation.

[0065] In an optional embodiment, two guide parts 400 are provided and respectively arranged on both sides of the moving component 200. The two guide parts 400 improve the directional constraint on the moving component 200, making the moving component more stable and reliable during the constraint and guidance process. It can quickly perform the correction operation in a short time. Moreover, the two guide parts 400 improve reliability, and it is sufficient to ensure that at least one guide part 400 can work normally. In specific implementation, the guide parts 400 can be arranged on the front and rear sides of the moving component 200 in the direction of movement, or on the left and right sides of the moving component 200 in the direction of movement. They can also be moved to avoid other equipment in the working environment according to the actual working conditions.

[0066] In an optional embodiment, the height of the first inclined surface 101 is the same as the stroke of the door opening arm 501.

[0067] When the door opening arm 501 moves from one end of the first inclined surface 101 to the other end under the drive of the door opening component 100, the door opening component 100 has been moved to the door opening position. The height of the first inclined surface 101 is the same as the stroke of the door opening arm 501. That is to say, after the door opening component 100 has been moved to the door opening position, the door opening component 100 no longer continues to lift the door opening arm 501 to move upward, maintaining the reliability of the door opening arm 501 in normal operation, avoiding unnecessary waste of lifting stroke, and making higher space utilization.
