Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of rail transport vehicle technology, and more specifically, to a steel plate rail transport vehicle. Background Technology

[0002] In the process of sheet material processing, the transportation of sheet materials is a necessary step. However, traditional sheet material transportation usually involves the use of both railcars and overhead cranes. The railcars first transport the sheet materials to the designated location, and then the overhead cranes lift them onto the operating platform. This transportation method requires the operation of both railcars and overhead cranes, which wastes time and manpower to some extent and affects production costs and pace.

[0003] Therefore, a type of transport railcar has been developed, which has certain lifting and automatic plate pushing functions. It can automatically push the plates on the transport railcar to the operating platform at a specified height. Specifically, the transport railcar has a lifting work platform with a movable push plate. Its movement mainly relies on the drive wheel on the push plate. The drive wheel rotates to drive the push plate to move on the lifting work platform, thereby realizing reciprocating movement to push the plates.

[0004] Although the method of moving the push plate by driving the drive wheel is more space-saving than that of pneumatic cylinders or hydraulic cylinders, it also has the following drawbacks: even if the drive wheel is locked and does not actively drive the push plate to move, the lack of limit on the drive wheel makes the push plate not stable enough when the transport railcar stops, and it is easy to shake under the action of external force, which does not meet the actual production requirements. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a steel plate transport railcar, which solves the technical problem in the related art that the push plate of the transport railcar driven by the drive wheel is prone to shaking and has poor stability when the machine is stopped.

[0006] According to one aspect, at least one embodiment of this disclosure provides a steel plate transport railcar, comprising:

[0007] A railcar base, on which a material-bearing platform is provided, the material-bearing platform having a material-bearing surface;

[0008] A push plate is reciprocatingly mounted on the material support platform and is rotatably connected to a drive wheel. The drive wheel abuts against the material support platform to drive the push plate so that the push plate pushes the material on the material support platform.

[0009] A limiting platform is raised and lowered on the material receiving platform and located on the moving path of the push plate. Both sides of the limiting platform have a limiting contact surface, which is used to contact the outer peripheral wall of the drive wheel and limit the drive wheel.

[0010] An elastic element, one end of which acts on the limiting platform and the other end of which acts on the receiving platform, is used to elastically push the limiting platform so that the limiting platform rises and exposes the receiving platform.

[0011] The drive wheel is configured to press down on the limiting platform after rotating.

[0012] For example, in a steel plate transport railcar provided in at least one embodiment of this disclosure, the push plate is rotatably connected to the drive wheel at both ends, and the material receiving platform has stepped surfaces at both ends. The drive wheel and the stepped surfaces correspond one-to-one. The drive wheel abuts against the bottom wall and side wall of the stepped surface, and the limiting platform is raised and lowered on the bottom wall of the stepped surface.

[0013] For example, in a steel plate transport railcar provided in at least one embodiment of this disclosure, two limiting plates are provided on the stepped surface. The two limiting plates are arranged at intervals along the moving path of the push plate, and the drive wheel is located between the two limiting plates. The limiting plates are used to limit the range of motion of the drive wheel.

[0014] For example, in a steel plate transport railcar provided in at least one embodiment of this disclosure, the limiting plate has a limiting contact surface two, which is used to contact the outer peripheral wall of the drive wheel and limit the drive wheel.

[0015] For example, in a steel plate transport railcar provided in at least one embodiment of this disclosure, the limiting platform has a force-bearing part located on one side of the push plate. The force-bearing part is raised and lowered on the material-bearing platform, located between the two limiting contact surfaces. The force-bearing part is configured to drive the limiting platform to descend after being pressed down by the plate.

[0016] For example, in a steel plate transport railcar provided in at least one embodiment of this disclosure, the force-bearing part is hemispherical.

[0017] For example, in a steel plate transport railcar provided in at least one embodiment of this disclosure, the force-bearing parts of the two limiting platforms are respectively close to both ends of the push plate.

[0018] For example, in a steel plate transport railcar provided in at least one embodiment of this disclosure, a limiting plate two is provided at one end of the material receiving platform. The limiting plate two is located on one side of the force-bearing part and is used to limit the initial position of the push plate.

[0019] For example, in a steel plate transport railcar provided in at least one embodiment of this disclosure, an electromagnetic block is provided on the side of the limiting plate near the push plate. The electromagnetic block is configured to attract the push plate after being energized, and to lock the push plate in the initial position of movement.

[0020] For example, in a steel plate transport railcar provided in at least one embodiment of this disclosure, a turntable is provided on the top surface of the railcar base, the rotation axis of the turntable is vertical, and the material support platform is raised and lowered on the turntable to control the direction of the push plate pushing the plate.

[0021] The beneficial effects of the embodiments disclosed herein are as follows:

[0022] 1. Improve the stability of the push plate: The limiting platform rises under the action of the elastic element, and the limiting contact surface on it can fit against the outer peripheral wall of the drive wheel to limit the drive wheel. This effectively prevents the push plate from shaking under the action of external force when the transport railcar stops due to the lack of limiting the drive wheel, making the push plate more stable as a whole and meeting the actual production requirements.

[0023] 2. Optimized space utilization: Compared with the traditional method of using cylinders or hydraulic cylinders to drive the push plate, the drive wheel that drives the push plate to move itself saves more space. In addition, the compact design of the limit table and other structures makes it suitable for use in production workshops with limited space. Attached Figure Description

[0038] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0039] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0040] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0041] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0043] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] like Figures 1-2 As shown, it illustrates a steel plate transport railcar in one embodiment of the present disclosure. During the stable positioning process of transporting the plate, the drive wheel 4 no longer actively drives the push plate 3 to move. At this time, under the action of the elastic member 6, the limiting platform 5 rises to expose the receiving platform 2. The limiting platform 5 uses its side limiting contact surface 501 to contact the outer peripheral wall of the drive wheel 4 to limit the drive wheel 4 and prevent the push plate 3 from shaking.

[0045] When transporting the steel plate, the steel plate is first placed on the square support platform 201 on the top of the support platform 2, which is installed on the top of the railcar base 1 via a hydraulic cylinder. The railcar is then started, moved to the designated position, and the support platform 2 is raised so that the support platform 201 is at the same height as the unloading surface. Then, the motor on the push plate 3 drives the drive wheel 4 to rotate, thereby moving the push plate 3 on the support platform 201 and pushing the steel plate to the unloading surface at the designated position.

[0046] During the transport of the sheet material, the drive wheel 4 will overcome the effect of the elastic element 6 by passing the limiting platform 5 and press the limiting platform 5 down below the receiving platform 2. Specifically, the drive wheel 4 will be below the contact plane between the receiving platform 2 and the limiting platform 2. The drive wheel 4 can continue to rotate to drive the push plate 3 to move and carry out the sheet material transport operation. The elastic element 6 only provides the limiting force for the push plate 3 to reset and stop and to abut against the limiting contact surface 501.

[0047] Traditional sheet material transportation uses a combination of a transport railcar and an overhead crane. After the transport railcar delivers the sheet material to the designated location, the overhead crane lifts it onto the operating platform. Alternatively, the pusher plate 3 can be driven by cylinders or hydraulic cylinders. Compared to this disclosure, the transport railcar used in this disclosure can independently complete the operation of transporting the sheet material to the operating platform at a designated height, simplifying the transportation process. Furthermore, in terms of drive, this disclosure uses a drive wheel 4 to drive the pusher plate 3, which saves more space. At the same time, the design of the limiting platform 5 further improves the overall structure and enables rapid limiting.

[0048] Specifically, regarding the components of this transport railcar, the railcar base 1 is the basic support structure of the entire transport railcar. A standard railcar is typically used, and several lifting hydraulic cylinders are arranged in a rectangular pattern on its top surface to control the lifting and lowering of the material support platform 2. The material support platform 2 can be a flat plate structure, stably mounted on the lifting hydraulic cylinders, facilitating stable movement of the material. The push plate 3 can achieve a movable connection with the top material support platform 201 via rollers or guide rails. The drive wheels 4 on the push plate 3, connected by a motor, can be made of rubber or other materials with a certain degree of friction to better contact the material support platform 2 and drive the push plate 3. Their number is generally even, symmetrically arranged at the bottom of both ends of the push plate 3. Additionally... Regarding the limiting platform 5, it can be raised and lowered on the moving path of the push plate 3 by a guide column, so as to fit against the outer peripheral wall of the drive wheel 4 to limit the push plate 3. At the same time, an elastic element 6 is arranged to give the limiting platform 5 a reset capability. It is sleeved on the guide column, and its two ends are respectively fixed to the bottom of the limiting platform 5 and the bottom of the groove opened by the material receiving platform 2 for the limiting platform 5 for raising and lowering. The guide column is also located in the groove to ensure the completion of the above transportation process. The limiting fitting surface 501 is an arc-shaped surface that fits the outer peripheral wall of the drive wheel 4 to better fit the limiting drive wheel 4. The limiting fitting surface 501 is opened on both sides to adapt to the reciprocating movement of the push plate 3. The limiting platform 5 can be pressed down through the limiting fitting surface 501.

[0049] like Figures 1-7 As shown, in some examples, both ends of the push plate 3 are connected to the drive wheel 4 by a motor, and the drive wheel 4 corresponds one-to-one with the stepped surfaces 202 at both ends of the support platform 2 and abuts against its bottom wall and side wall, forming a stable three-point support drive structure. During the process of pushing the steel plate, this structure can effectively prevent the push plate 3 from shifting or twisting in the horizontal direction, making the push plate 3 run more smoothly. In addition, the setting position of the limiting platform 5 is optimized, and it is arranged on the bottom wall of the stepped surface 202 to avoid interference with the plate on the support platform 201.

[0050] Both of its vertical stepped surfaces 202 extend vertically downward relative to the material receiving platform 201, such as Figure 1 As shown, this ensures that the circular drive wheel 4, with a diameter greater than that of the push plate 3, can stably abut against the bottom and side walls of the stepped surface 202, thus fulfilling its function.

[0051] like Figures 8-10 As shown, in some examples, two limiting plates 7 are arranged at intervals along the moving path of the push plate 3 on the stepped surface 202, with the drive wheel 4 located between them. This can precisely limit the movement range of the drive wheel 4 and prevent it from detaching from the material support. Furthermore, a limiting contact surface 701 that fits against the outer peripheral wall of the drive wheel 4 is opened on the limiting plate 7. Compared with simple blocking and restriction, this contact limiting method is consistent with the limiting method of the limiting platform 5, which can more tightly constrain the drive wheel 4 and prevent the drive wheel 4 from shaking.

[0052] Specifically, the two limiting plates 7 are welded or integrally formed at both ends of the stepped surface 202 along the path of the push plate 3. Alternatively, adjustable limiting plates can be used. By setting grooves and adjusting bolts on the stepped surface 202, the distance between the two limiting plates 7 can be flexibly adjusted according to the different specifications of the drive wheel 4 or the needs of the transportation task, thereby enhancing the versatility of the equipment. In addition, the limiting plates 7 can be made of wear-resistant metal materials, such as alloy steel, to ensure that the limiting effect is durable and reliable. Alternatively, a replaceable wear-resistant rubber patch can be pasted on the surface of the limiting plates 7 as the limiting contact surface 701. When the patch is worn, it can be easily and quickly replaced.

[0053] like Figures 1-11 As shown, in some examples, the force-bearing part 502 of the limiting platform 5 can drive the limiting platform 5 to descend after the plate is pressed down, simplifying the operation process. Compared with the previous method of relying on the rotation of the drive wheel 4 to press down the limiting platform 5, this design activates the lowering mechanism of the limiting platform 5 during the plate placement stage. The operator only needs to place the plate on the support platform 201 without waiting for the drive wheel 4 to start pressing down the limiting platform 5, simplifying the steps. At the same time, it does not affect the function of limiting the drive wheel 4 through the elastic element 6. That is, after the steel plate is placed, the limiting effect of the limiting platform 5 on the drive wheel 4 is released, and the steel plate is used instead. The drive wheel 4 will not wobble. Then, the drive wheel 4 can be driven to push the steel plate stably.

[0054] Previously, the drive wheel 4 would rotate and press down on the limiting platform 5. This process depended on the rotation of the drive wheel 4, and the limiting platform 5 would only be pressed down when the transport railcar started and the drive wheel 4 began to drive the push plate 3 to move. Now, when the plate is placed, the weight of the plate directly acts on the force-bearing part 502, causing the limiting platform 5 to descend. The difference lies in the timing and power source of triggering the descent of the limiting platform 5. The new design advances the triggering time to the plate placement stage, and the power source changes from the rotation of the drive wheel 4 to the weight of the plate.

[0055] Specifically, after the board is placed, the force-bearing part 502 is pressed down by the board, which drives the limiting platform 5 to descend as a whole. The limiting contact surface 501 releases the limiting of the drive wheel 4. The drive wheel 4 rotates and drives the push plate 3 to move, starting to push the board for transportation. The board moves away from the force-bearing part 502. Under the action of the elastic element 6, the limiting platform 5 rises, and the limiting contact surface 501 is lifted. During the reset process of the push plate 3, the drive wheel 4 presses down on the limiting platform 5 again, resets to the initial position of movement, and the limiting platform 5 rises again and contacts the outer peripheral wall of the drive wheel 4 again to limit the drive wheel 4 and prevent the push plate 3 from shaking.

[0056] like Figure 11 As shown, in some examples, when the hemispherical force-bearing part 502 contacts the board, it is a point or small-area contact. Compared with a plane or other shapes, this contact can effectively reduce the friction between the board and the force-bearing part 502 during placement, reduce the risk of scratches and wear on the board surface caused by friction, and better protect the surface quality of the board. At the same time, it also has a certain positioning and guiding function. When placing the board, the operator can more easily align the board with the force-bearing part 502 to achieve precise placement.

[0057] like Figures 8-9 As shown, in some examples, the push plate 3 is provided with force-bearing parts 502 at both ends. When the board is placed on the support platform 2, the gravity at both ends of the board acts on the corresponding force-bearing parts 502. This allows the push plate 3 to be evenly stressed in the initial stage, avoiding the phenomenon of tilting or jamming caused by excessive force on one end of the push plate 3 due to deviation in the placement position of the board or shift in the center of gravity. This ensures that the push plate 3 pushes the board smoothly.

[0058] like Figures 8-9 As shown, in some examples, a limiting plate 2 8 is set at the initial position of the push plate 3 on the material receiving platform 201 to clearly define the initial position of the push plate 3. Based on this, in order to avoid the influence of external forces on the position of the push plate 3 due to misoperation, even though the elastic element 6 provides a limiting force, an electromagnetic block 9 is provided on the side of the limiting plate 2 8 near the push plate 3. After the electromagnetic block 9 is energized, it attracts the push plate 3, which can more firmly lock the push plate 3 in the initial position of movement. Before the transport railcar starts, even if it is subjected to slight external vibration or external force interference, the push plate 3 will not be displaced. It only performs the energizing and attracting operation when the push plate 3 moves and resets and is not working.

[0059] like Figure 12 As shown, in some examples, a vertically rotatable turntable 10 is provided on the top surface of the railcar base 1, and the material support platform 2 is raised and lowered on the turntable 10. This allows the direction of the push plate 3 pushing the plate to be flexibly adjusted. In a complex production workshop environment, the transport direction of the plate can be easily changed according to the location, layout and transport route requirements of different processing equipment, without the need for the railcar to perform complex turning operations.

[0060] Specifically, the rotary table 10 is installed on the top surface of the railcar base 1. Its rotation mechanism can adopt the method of bearing and rotating shaft cooperation to ensure that the rotary table 10 can rotate smoothly around the vertical axis. Furthermore, the material support platform 2 is set on the rotary table 10 through a hydraulic cylinder to complete the above actions.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
