Description

Technical Field

[0001] This utility model relates to the field of freight equipment technology, and more specifically, to a self-tipping device and a self-tipping vehicle. Background Technology

[0002] Railway tippler cars are mainly used for transporting bulk cargo such as mineral powder, ore, gravel, coal, slag, steel slag, and building materials.

[0003] Existing railway tipplers typically employ spring-loaded hinged elbows. The movement of these elbows drives the opening and closing of the connected side doors. In other words, the spring structure provides the necessary support force for the side doors to open and close. However, springs can deform over time, resulting in insufficient support force and affecting the opening and closing of both side doors. For example, spring deformation reduces support force, preventing the hinged elbows from providing enough support when the side doors close, thus hindering closure. Furthermore, existing hinged elbow structures are complex, including side door hinges, square supports, hand supports, and springs. The numerous connections and complex coordination among these components mean that misalignment or malfunction in any one location can lead to difficulties in lowering the car body, high inspection and maintenance costs, reduced freight transport efficiency, and even transport accidents. Utility Model Content

[0004] The problem this invention addresses is how to improve the safety and efficiency of railway tippler transportation.

[0005] To solve the above problems, this utility model provides a self-tipping device and a self-tipping vehicle.

[0006] In the first aspect, this utility model provides a self-tipping vehicle tilting device and a self-tipping vehicle, including a support beam, a car body frame, a hinge, a short restraining elbow and a long restraining elbow;

[0007] The underframe of the carriage is positioned above the support beam, and the extension direction of the support beam is the same as the length direction of the underframe of the carriage.

[0008] The plurality of the flaps are respectively arranged at intervals on both sides of the underframe of the carriage, and each flap is hinged to the underframe of the carriage.

[0009] The multiple short restraining elbows and the multiple long restraining elbows are staggered along the length direction of the carriage underframe and are respectively hinged to the carriage underframe. The extension direction of the short restraining elbows and the long restraining elbows is parallel to the width direction of the carriage underframe.

[0010] One end of the short restraining elbow and the long restraining elbow are rolled onto the corresponding hinge, and the other end is attached to the support beam.

[0011] Optionally, the underframe of the carriage includes crossbeams and longitudinal beams;

[0012] Multiple crossbeams are spaced apart along the length of the carriage underframe, and the extension direction of the crossbeams is the same as the width direction of the carriage underframe.

[0013] Multiple longitudinal beams are spaced apart along the width direction of the carriage underframe, and the extending direction of the longitudinal beams is the same as the length direction of the carriage underframe;

[0014] The hinge is connected between any two adjacent crossbeams.

[0015] Optionally, the fold includes an upper fold and a lower fold that are connected to each other;

[0016] The upper hinge is located on the side wall of the carriage underframe;

[0017] The lower hinge has a C-shaped cross-section in the vertical direction, and the inner arc surface of the lower hinge has a protrusion. The protrusion is hinged to the carriage base frame, and one end of the short restraining elbow and the long restraining elbow are rolledly connected to the inner arc surface.

[0018] Optionally, the short restraint elbow and the long restraint elbow are respectively provided with through holes, which are configured to allow the lower fold to pass through.

[0019] Optionally, a limiting member is provided between any two adjacent crossbeams, and the lower flap is used to abut against the limiting member after passing through the through hole, so that the plane where the upper flap is located is on the same plane as the upper end surface of the carriage base.

[0020] Optionally, when the carriage underframe is not tilted, the upper hinge is perpendicular to the carriage underframe.

[0021] Optionally, the short restraint elbow includes a first short body and a second short body connected to each other, and the first short body and the second short body are set at an obtuse angle. The second short body is used to overlap the support beam, and a first roller is provided at the end of the first short body away from the second short body for rolling along the inner arc surface.

[0022] Optionally, the long suppressing elbow includes a first long body and a second long body connected to each other, and the first long body and the second long body are set at an obtuse angle. The second long body is used to overlap the support beam, and a second roller is provided at the end of the first long body away from the second long body for rolling along the inner arc surface.

[0023] Optionally, the upper and lower flaps are cast separately and then connected by welding.

[0024] Secondly, this utility model provides a self-tipping vehicle, including the self-tipping vehicle tipping device as described above.

[0025] The beneficial effects of the self-tipping device and the self-tipping vehicle of this utility model are: the support beams provide support for the short restraint elbow, the long restraint elbow and the underframe of the carriage when the self-tipping vehicle is running, ensuring the stability of each structure when the self-tipping vehicle is running. Multiple hinges are hinged at intervals along the two side walls extending along the length of the car body underframe. Multiple short and long restraining elbows are staggered and hinged along the length of the car body underframe. One end of the short and long restraining elbows is rolled onto the corresponding hinge, and the other end is attached to the support beam. When tilting, the ends of the short and long restraining elbows on the door opening side of the car body underframe that are rolled onto the hinges roll upwards along the hinges, causing the hinges to tilt and thus opening the side wall on that side for unloading. On the lifting side of the car body underframe, the car body underframe, hinges, and short and / or long restraining elbows interact to form a fixed locking state, so that the side wall on that side is always closed, preventing the side wall on the lifting side of the car body underframe from opening uncontrollably during tilting and causing the goods to scatter. Compared with the tilting device that uses a spring structure to provide support for the side door in related technologies, its structure and connection method are simple, the tilting and unloading process is smooth, and it effectively avoids transportation accidents caused by the door jamming due to the complex cooperation of various structures, which leads to the overturning of the carriage or the difficulty in unloading the carriage underframe. At the same time, it avoids the situation where the carriage doors open on both sides due to insufficient support force of the spring after long-term use, thus effectively improving the safety and efficiency of cargo transportation.

[0044] like Figures 1 to 7 As shown, the present invention provides a self-tipping vehicle tilting device, which includes a support beam 1, a carriage base frame 2, a hinge 3, a short restraining elbow 4, and a long restraining elbow 5;

[0045] The underframe 2 of the carriage is disposed above the support beam 1, and the extension direction of the support beam 1 is the same as the length direction of the underframe 2 of the carriage.

[0046] Multiple hinges 3 are respectively arranged at intervals along the two side walls extending along the length direction of the carriage base frame 2, and each hinge 3 is respectively hinged to the carriage base frame 2;

[0047] Multiple short restraining elbows 4 and multiple long restraining elbows 5 are staggered along the length direction of the carriage underframe 2 and are respectively hinged to the carriage underframe 2. The extending directions of the short restraining elbows 4 and long restraining elbows 5 are parallel to the width direction of the carriage underframe 2 (e.g., ...). Figure 3 Parallel to the X-axis direction;

[0048] One end of the short restraining elbow 4 and the long restraining elbow 5 are rolledly connected to the corresponding hinge 3, and the other end is attached to the support beam 1.

[0049] Specifically, along the length direction of the underframe 2 of the carriage (e.g. Figure 3 At the bottom of both sides extending along the Y-axis, there are cylinders. The cylinders extend to lift one side of the chassis 2 connected to them, thus achieving the tilting operation. It should be noted that the cylinders on both sides do not extend at the same time during the tilting operation.

[0050] Specifically, the support beam 1 is used to support the short restraint elbow 4, the long restraint elbow 5 and the undercarriage frame 2 when the self-tipping vehicle is not overturned, so as to ensure the stability of each structure during the operation of the self-tipping vehicle and to support the cargo. For example, the support beam 1 can be connected to the fixed structure on the axle through bearings to ensure that the support beam 1 remains fixed during the operation of the self-tipping vehicle.

[0051] like Figure 1 As shown, the underframe 2 of the carriage is positioned above the support beam 1, and the length of both is such that... Figure 3 Along the same Y-axis direction, support beam 1 supports the underframe 2 of the carriage. The underframe 2 of the carriage is aligned with the underframe 2 in its height direction (e.g., along the Y-axis direction). Figure 3 Multiple side walls are provided in the Z-axis direction to form a box structure for carrying goods. Multiple hinges 3 are provided at intervals on the two side walls extending along the length of the carriage base 2, and each hinge 3 is hinged to the carriage base 2. When the self-tipping vehicle is overturned, the hinge 3 can rotate relative to the carriage base 2 to drive the corresponding side wall to open and close, so as to realize the storage, transportation and unloading of goods.

[0052] Multiple short restraining elbows 4 and multiple long restraining elbows 5 are staggered along the length of the car body underframe 2 and are hinged to the car body underframe 2 respectively. Taking one side of the car body underframe 2 as an example, they are arranged in the order of short restraining elbow 4, long restraining elbow 5, short restraining elbow 4, long restraining elbow 5, and short restraining elbow 4. The other side follows the same order. It should be noted that the length of the short restraining elbow 4 is usually less than half the width of the car body underframe 2, while the length of the long restraining elbow 5 is usually greater than half the width of the car body underframe 2. Therefore, when setting the short restraining elbows 4, the short restraining elbows 4 on the two side walls can be arranged opposite each other, while the long restraining elbows 5 can be arranged according to a preset spacing to ensure that the forces on both sides of the car body underframe 2 are balanced along the length direction. For example... Figure 3 As shown, the short restraining elbow 4 near the A direction side can be the first short restraining elbow, and the long restraining elbow 5 can be the first long restraining elbow. The short restraining elbow 4 near the B direction side can be the second short restraining elbow, and the long restraining elbow 5 can be the second long restraining elbow. The first short restraining elbow and the second long restraining elbow are arranged opposite each other. In the width direction of the car body underframe 2, the first short restraining elbow and the second short restraining elbow are on the same straight line. The first long restraining elbow and the second long restraining elbow are staggered in the width direction of the car body underframe 2, with a spacing of [missing information]. Figure 3 The length L can be 360mm to prevent frictional collision between the first and second long restraint elbows.

[0053] Each short restraint elbow 4 and each long restraint elbow 5 corresponds to a hinge 3. When the self-tipping vehicle is not tipping over, such as... Figure 1 and Figure 2 As shown (where, Figure 2 This is a side view of the tilting device. Figure 2 This is a perspective view of the test section of the tilting device, in which... Figure 1 The long suppressor elbow is 5. Figure 3 The long suppression elbow 5 and short suppression elbow 4 are marked in the text. Figure 3 The short restraint elbow 4 and the long restraint elbow 5, as marked in the figure, are rolled at one end and connected to the bottom of the corresponding hinge 3. The other end of each short restraint elbow 4 and each long restraint elbow 5 overlaps the support beam 1 and abuts against the bottom surface of the carriage underframe 2. When the self-tipping vehicle tipes over, as... Figures 4 to 6 As shown, on the door opening side (near direction A) of the car chassis 2, the short restraining elbow 4 and the long restraining elbow 5 are tumblingly connected to the hinge 3 at one end. The hinge 3 tilts to open the side wall on that side for unloading. Meanwhile, due to the tilting of the car chassis 2, the other end of the short restraining elbow 4 and the long restraining elbow 5 is raised at the point of contact with the car chassis 2, and remains constantly attached to the support beam 1, ensuring the stability of the car chassis 2. On the lifting side (near direction B) of the car chassis 2, the short restraining elbow 4 and the long restraining elbow 5 are tumblingly connected to the hinge 3. One end is connected to the bottom of the corresponding hinge 3. The other ends of the short restraining elbow 4 and the long restraining elbow 5 are lifted from the support beam 1 due to the tilting and abut against the bottom surface of the car chassis 2. The car chassis 2, hinge 3 and short restraining elbow 4 and / or long restraining elbow 5 interact to lock each other, so that the hinge 3 on the side wall of the lifting side of the car chassis 2 remains in the closed state when the car is not tilted. This ensures that the side wall is always closed, and the cargo is only poured on the opposite side, avoiding the situation where the side wall of the lifting side of the car chassis 2 opens uncontrollably and the cargo scatters when the car is tilted.

[0054] It should be noted that the underframe 2, short restraint elbow 4, hinge 3, support beam 1, and long restraint elbow 5 are all made of a relatively rigid metal material (such as high-strength alloy steel).

[0055] In this embodiment, a support beam 1 is provided to support the short restraining elbow 4, the long restraining elbow 5, and the carriage underframe 2 during self-tipping operation, ensuring the stability of each structure during self-tipping operation. Multiple hinges 3 are respectively hinged at intervals along the two side walls extending along the length direction of the carriage underframe 2. Multiple short restraining elbows 4 and multiple long restraining elbows 5 are staggered and hinged along the length of the car chassis 2. One end of the short restraining elbows 4 and long restraining elbows 5 is rolled to the corresponding hinge 3, and the other end is attached to the support beam 1. When tilting, the ends of the short restraining elbows 4 and long restraining elbows 5 on the door opening side of the car chassis 2 that are rolled to the hinge 3 roll upward along the hinge 3. The hinge 3 tilts to open the side wall on that side for unloading. On the lifting side of the car chassis 2, the car chassis 2, hinge 3, and short restraining elbows 4 and / or long restraining elbows 5 interact to form a fixed locking state, so that the side wall is always in a closed state, preventing the side wall on the lifting side of the car chassis 2 from opening uncontrollably on both sides and causing the goods to scatter when tilting. Compared with the tipping device that uses a spring structure to provide support for the side door in related technologies, its structure and connection method are simple, and the tipping and unloading process is smooth. It effectively avoids transportation accidents caused by the door jamming due to the complex cooperation of various structures, which leads to the tipping of the carriage or the difficulty of unloading the carriage underframe 2. At the same time, it avoids the situation where the carriage doors open on both sides due to insufficient support force of the spring after long-term use, thus effectively improving the safety and efficiency of cargo transportation.

[0056] Optionally, the underframe 2 of the carriage includes a crossbeam 21 and a longitudinal beam 22;

[0057] Multiple crossbeams 21 are spaced apart along the length of the carriage underframe 2, and the extending direction of the crossbeams 21 is the same as the width direction of the carriage underframe 2;

[0058] Multiple longitudinal beams 22 are spaced apart along the width direction of the carriage underframe 2, and the extending direction of the longitudinal beams 22 is the same as the length direction of the carriage underframe 2;

[0059] The hinge 3 is hinged between any two adjacent crossbeams 21.

[0060] Specifically, the carriage base frame 2 is composed of interconnected crossbeams 21 and longitudinal beams 22, for example, the crossbeams 21 and longitudinal beams 22 form a structure as follows: Figure 3 The mesh structure shown can have crossbeams 21 and longitudinal beams 22 as box-type beams. It should be noted that, to prevent cargo from leaking through the gaps, a structure such as a steel plate will be installed on the underframe 2 of the carriage to form a closed box-type loading carriage structure with the side walls connected to the hinges 3. The hinges 3 are hinged between any two adjacent crossbeams 21 and are located at the ends of the crossbeams 21.

[0061] Optionally, the fold 3 includes an upper fold 31 and a lower fold 32 that are connected to each other;

[0062] The upper hinge 31 is disposed on the side wall of the carriage underframe;

[0063] The lower hinge 32 has a C-shaped cross-section in the vertical direction, and the inner arc surface of the lower hinge 32 is provided with a protrusion 321. The protrusion 321 is hinged to the carriage base frame 2, and one end of the short restraining elbow 4 and the long restraining elbow 5 is rolledly connected to the inner arc surface.

[0064] Specifically, fold 3 includes an upper fold 31 and a lower fold 32, such as... Figure 1 , Figure 2 , Figures 4 to 7 As shown, the vertical interface of the lower hinge 32 is C-shaped. One end of the short restraining elbow 4 and the long restraining elbow 5 is rolled onto its inner arc surface, and a protrusion 321 is provided on its inner arc surface. Through this protrusion 321, the carriage base frame 2 is hinged to the short restraining elbow 4 and the long restraining elbow 5. It should be noted that, in order to prevent the short restraining elbow 4 and the long restraining elbow 5 from dislodging when rolling on the inner arc surface of the lower hinge 32, limiting blocks can also be provided at both ends of the inner arc surface.

[0065] The upper hinge 31 is used to connect with the two side walls extending along the length of the carriage underframe 2 and to the top of the lower hinge 32. The short restraining elbow 4 and the long restraining elbow 5 roll on the inner arc surface of the lower hinge 32, cooperating with each other to drive the side walls to open and close, realizing the storage, transportation and dumping of materials, avoiding the complex structural connection structure in related technologies that causes the door to jam and the vehicle to overturn.

[0066] It should be noted that the angle between the protrusion 321 and the inner arc surface is an acute angle. When the underframe 2 of the carriage tilts to this side, the ends of the short restraining elbow 4 and the long restraining elbow 5 on this side, which are connected to the inner arc surface, will roll directly to the position between the protrusion 321 and the inner arc surface according to the shape of the inner arc surface. The lower hinge 32 will flip, causing the upper hinge 31 to flip as well. Figure 4 and Figure 6 As shown, when the ends of the short restraining elbow 4 and the long restraining elbow 5, which are connected to the inner arc surface, roll directly to the position between the protrusion 321 and the inner arc surface according to the shape of the inner arc surface, the angle between the carriage base frame 2 and the horizontal plane can be 35°, so that the side wall connected to the upper hinge 31 can be quickly opened to a position where the cargo can be dumped. This allows for early door opening during the carriage base frame 2's tilting process, enabling early unloading and preventing the vehicle from tipping over due to uneven loading caused by the cargo tilting in the same direction. Then, due to the weight change caused by the cargo dumping onto the carriage base frame 2, or when the cylinder pushes the carriage base frame 2 to lift to its maximum height on one side, such as... Figure 5 As shown, the angle between the underframe 2 of the carriage and the horizontal plane can be 45°.

[0067] Optionally, the short suppressing elbow 4 and the long suppressing elbow 5 are respectively provided with through holes 6, which are configured to allow the lower flap 32 to pass through, so as to realize the mutual cooperation between the short suppressing elbow 4 and the long suppressing elbow 5 and the lower flap 32.

[0068] Optionally, a limiting member 211 is provided between any two adjacent crossbeams 21. The lower flap 32 is used to abut against the limiting member 211 after passing through the through hole 6, so that the plane where the upper flap 31 is located is on the same plane as the upper end surface of the carriage base 2. While ensuring that the goods can be smoothly poured through the upper flap 31, it prevents the short restraining elbow 4 and the long restraining elbow 5 from being dislodged from the lower flap 31 by force at the connection points with the inner arc surface of the lower flap 31, thus ensuring the normal operation of the tipping device.

[0069] Optionally, when the carriage base frame 2 is not tilted, the upper hinge 31 is perpendicular to the carriage base frame 2.

[0070] Specifically, in related technologies, the side view cross-section shape of a self-tipping vehicle is usually a trapezoidal structure that is wider at the top and narrower at the bottom. However, if a vehicle of this shape is used to transport goods, the goods will continuously exert a large pressure on the side wall or the upper part of the side door during transportation. This causes the spring structure connected to the side door through the suppressing elbow to always be in a state of high tension, which can easily lead to insufficient support force of the spring structure. Consequently, the side door will open uncontrollably, resulting in a transportation accident. Therefore, in this embodiment, the upper hinge 31 is set perpendicular to the vehicle chassis 2, so that the side wall and the vehicle chassis 2 are set perpendicular to each other, reducing the pressure of the goods on the side wall, thereby reducing the pressure on the suppressing elbow and preventing the problem of uncontrolled door opening caused by closure failure.

[0071] Optionally, the short suppressing elbow 4 includes a first short body 41 and a second short body 42 connected to each other, and the first short body 41 and the second short body 42 are set at an obtuse angle. The second short body 42 is used to overlap the support beam 1. A first roller 43 is provided at the end of the first short body 41 away from the second short body 42 for rolling along the inner arc surface.

[0072] Specifically, the first short body 41 and the second short body 42 in the short restraint elbow 4 are set at an obtuse angle, so that there is a certain distance difference in the vertical direction between the opposite ends of the first short body 41 and the second short body 42, which facilitates the design and installation of the hinge 3. Furthermore, the second short body 42 overlaps the support beam 1 to ensure the stability of the tilting device. A first roller 43 is provided at the end of the first short body 41 away from the second short body 42 for rolling along the inner arc surface of the lower hinge 31, thereby ensuring the smoothness of the side wall opening and closing.

[0073] Optionally, the long suppressing elbow 5 includes a first long body 51 and a second long body 52 connected to each other, and the first long body 51 and the second long body 52 are set at an obtuse angle. The second long body 52 is used to overlap the support beam 1. A second roller 53 is provided at the end of the first long body 51 away from the second long body 52 for rolling along the inner arc surface.

[0074] Specifically, the structure and function of the long suppressing elbow 5 are the same as those of the short suppressing elbow 4, and will not be repeated here.

[0075] Optionally, the upper flap 31 and the lower flap 32 are cast separately and then connected by welding.

[0076] Specifically, such as Figure 7 As shown, dividing the hinge 3 into upper hinge 31 and lower hinge 32 for separate casting and welding can reduce the proportion of castings, thereby reducing the weight of hinge 3 and thus reducing the overall weight of the vehicle. Due to the rail axle load limit, this avoids the impact on cargo transportation efficiency caused by the excessive weight of the tilting device.

[0077] This utility model provides a self-tipping vehicle, including the self-tipping vehicle tipping device described above.

[0078] The advantages of the self-tipping vehicle in this embodiment compared to the prior art are the same as those of the self-tipping vehicle tipping device described above, and will not be repeated here.

[0079] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
