Description

Technical Field

[0001] The present invention relates to the technical field of freight equipment, and in particular to a self-tipping vehicle tipping device and a self-tipping vehicle. Background Art

[0002] Railway self-dumping cars are mainly used to transport bulk goods such as mineral powder, ore, gravel, coal blocks, slag, steel slag, and building materials.

[0003] Existing railway self-tipping cars usually use a hinged restraining elbow with a spring structure, and the operation of the hinged restraining elbow drives the side door connected to it to open and close, that is, the spring structure drives the hinged restraining elbow to cooperate and operate, providing the supporting force required for the side door to open and close. However, the spring may be deformed due to long-term use, resulting in insufficient supporting force provided by the spring, which in turn affects the opening and closing of the double side doors. For example, the spring is deformed and the supporting force is reduced. When the side door is closed, it cannot provide sufficient supporting force to the hinged restraining elbow, and thus cannot drive the side door to close. In addition, the existing hinged restraining elbow has a complex structure. For example, the existing hinged structure includes side door hinges, square supports, human supports, springs and other structures. The connection positions of each structure are many and the coordination is complex. If one position is misaligned or fails, it will make it difficult to get off the carriage frame, and the inspection and maintenance costs will be high, affecting the efficiency of cargo transportation and even causing transportation accidents. Summary of the invention

[0004] The problem solved by the invention is how to improve the transportation safety and transportation efficiency of railway self-dumping cars.

[0005] In order to solve the above problems, the present invention provides a self-tipping vehicle tipping device and a self-tipping vehicle.

[0011] Optionally, the car body underframe includes cross beams and longitudinal beams;

[0012] A plurality of the cross beams are arranged at intervals along the length direction of the car body underframe, and the extending direction of the cross beams is the same as the width direction of the car body underframe;

[0013] A plurality of the longitudinal beams are arranged at intervals along the width direction of the car body underframe, and the extending direction of the longitudinal beams is the same as the length direction of the car body underframe;

[0014] The hinge is hinged between any two adjacent cross beams.

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

[0016] The upper hinge is arranged on the side wall of the car body underframe;

[0017] The cross section of the lower hinge is C-shaped in the vertical direction, and a protruding portion is arranged on the inner arc surface of the lower hinge. The protruding portion is hinged to the car body underframe, and one ends of the short restraint elbow and the long restraint elbow are rollingly connected to the inner arc surface.

[0018] Optionally, through holes are respectively formed in the short restraint elbow and the long restraint elbow, and the through holes are configured to allow the lower hinge to pass through.

[0019] Optionally, limiting members are respectively arranged between any two adjacent cross beams. After passing through the through holes, the lower hinge is used to abut against the limiting members so that the plane where the upper hinge is located and the upper end surface of the car body underframe are in the same plane.

[0020] Optionally, when the car body underframe is not overturned, the upper hinge and the car body underframe are perpendicular to each other.

[0021] Optionally, the short restraint elbow includes a first short main body and a second short main body which are connected to each other, and an obtuse angle is formed between the first short main body and the second short main body. The second short main body is used for lapping on the support beam, and a first roller is arranged at one end of the first short main body away from the second short main body for rolling along the inner arc surface.

[0022] Optionally, the long restraint elbow includes a first long main body and a second long main body which are connected to each other, and an obtuse angle is formed between the first long main body and the second long main body. The second long main body is used for lapping on the support beam, and a second roller is arranged at one end of the first long main body away from the second long main body for rolling along the inner arc surface.

During tipping, the ends of the short restraint elbow and the long restraint elbow on the door-opening side of the carriage chassis that are rotatably connected to the hinge roll upward along the hinge to drive the hinge to tip and then drive the side wall on that side to open for discharging. On the lifting side of the carriage chassis, the carriage chassis, the hinge, and the short restraint elbow and / or the long restraint elbow interact to form a fixed clamping state, so that the side wall on that side always remains in a closed state, avoiding the situation where the side wall on the lifting side of the carriage chassis is uncontrollably opened on both sides during tipping, resulting in the scattering of goods. Compared with the tipping device that uses a spring structure to provide support force for the side door in the related art, its structure and connection method are simple, the tipping and car-falling processes are smooth, effectively avoiding transportation accidents caused by the complex cooperation of each structure resulting in the jamming of the door opening, leading to the tipping of the carriage or the difficulty of the carriage chassis falling, and at the same time avoiding the situation of the carriage opening on both sides due to insufficient support force of the spring after long-term use, effectively improving the safety and transportation efficiency of goods transportation.

It should be noted that the concepts such as "first" and "second" mentioned in the present invention are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0043] It should be noted that the modifications of "one" and "plural" mentioned in the present invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise clearly specified in the context, it should be understood as "one or more".

[0044] As Figures 1 to 7 shown, a self-dumping tipping device provided by an embodiment of the present invention includes a support beam 1, a carriage chassis 2, hinges 3, short restraining elbows 4 and long restraining elbows 5;

[0045] The carriage chassis 2 is disposed above the support beam 1, and the extending direction of the support beam 1 is the same as the length direction of the carriage chassis 2;

[0046] A plurality of the hinges 3 are respectively arranged at intervals along both side walls extending in the length direction of the carriage chassis 2, and each hinge 3 is respectively hinged to the carriage chassis 2;

[0047] A plurality of the short restraining elbows 4 and a plurality of the long restraining elbows 5 are arranged alternately along the length direction of the carriage chassis 2, and are respectively hinged to the carriage chassis 2. The extending directions of the short restraining elbows 4 and the long restraining elbows 5 are parallel to the width direction of the carriage chassis 2 (such as the X-axis direction in Figure 3 );

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

[0049] Specifically, on both bottom sides of the carriage chassis 2 extending in the length direction (such as the Y-axis direction in Figure 3 ), cylinders are provided. The cylinders extend to lift one side of the carriage chassis 2 connected thereto to achieve tipping. It should be noted that when performing the tipping operation, the cylinders on both sides will not extend simultaneously.

[0050] Specifically, the support beam 1 is used to support the short restraint elbow 4, the long restraint elbow 5 and the car body underframe 2 when the self-dumping vehicle is not overturned, ensuring the stability of each structure during the operation of the self-dumping vehicle to carry goods. 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-dumping vehicle.

[0051] As Figure 1 shown, the car body underframe 2 is arranged above the support beam 1, and their length directions (such as the Y-axis direction in Figure 3 ) are the same. The support beam 1 is used to support the car body underframe 2. The car body underframe 2 is provided with a plurality of side walls in its height direction (such as the Z-axis direction in Figure 3 ) to form a box structure for loading goods. A plurality of hinges 3 are respectively arranged at intervals on the two side walls extending along the length direction of the car body underframe 2, and each hinge 3 is hinged to the car body underframe 2. When the self-dumping vehicle is overturned, the hinge 3 can rotate relative to the car body underframe 2 to drive the corresponding side wall to open and close, realizing the storage, transportation and dumping of goods.

[0052] A plurality of short restraint elbows 4 and a plurality of long restraint elbows 5 are arranged alternately along the length direction of the car body underframe 2 and are respectively hinged to the car body underframe 2. Taking one side of the car body underframe 2 in its length direction as an example, they are arranged in the order of short restraint elbow 4, long restraint elbow 5, short restraint elbow 4, long restraint elbow 5 and short restraint elbow 4. The other side has the same order. It should be noted that the length of the short restraint elbow 4 is usually less than half of the width of the car body underframe 2, while the length of the long restraint elbow 5 is usually greater than half of the width of the car body underframe 2. Thus, when arranging the short restraint elbows 4, the short restraint elbows 4 on the two side walls can be arranged opposite to each other, and the long restraint elbows 5 can be arranged at a preset interval to ensure the balanced force on both sides of the car body underframe 2 along the length direction. For example Figure 3 shown, the short restraint elbow 4 near the A-direction side can be the first short restraint elbow, the long restraint elbow 5 can be the first long restraint elbow, the short restraint elbow 4 near the B-direction side can be the second short restraint elbow, and the long restraint elbow 5 can be the second long restraint elbow. The first short restraint elbow and the second long restraint elbow are arranged opposite to each other. In the width direction of the car body underframe 2, the first short restraint elbow and the second short restraint elbow are on the same straight line, and the first long restraint elbow and the second long restraint elbow are arranged alternately in the width direction of the car body underframe 2, and their interval is Figure 3 L in

[0053] which can be 360 mm to prevent the first long restraint elbow and the second long restraint elbow from rubbing and colliding. Figure 1 and Figure 2 shown (where Figure 2 is the side view of the tipping device, Figure 2 is the perspective view of the test part of the tipping device, whereFigure 1 The long suppression elbow 5 in Figure 3 The long suppression elbow 5 and the short suppression elbow 4 marked in Figure 3 One end of the short suppression elbow 4 and the long suppression elbow 5 marked in is roll-connected to the bottom of the corresponding hinge 3, and the other end of each short suppression elbow 4 and each long suppression elbow 5 overlaps on the support beam 1 and abuts against the bottom surface of the car body frame 2; when the self-unloading vehicle is overturned, as Figures 4 to 6 shown, the ends of the short suppression elbow 4 and the long suppression elbow 5 on the door side (the side close to the A direction) of the car body frame 2 that are roll-connected to the hinge 3 roll upward along the hinge 3, and the hinge 3 overturns to drive the side wall on this side to open for discharging materials. And the other ends of the short suppression elbow 4 and the long suppression elbow 5 are lifted due to the overturning of the car body frame 2, and the position where the car body frame 2 contacts here is lifted, and it always overlaps on the support beam 1 to ensure the stability of the car body frame 2; the ends of the short suppression elbow 4 and the long suppression elbow 5 on the lifting side (the side close to the B direction) of the car body frame 2 that are roll-connected to the hinge 3 are connected to the bottom of the corresponding hinge 3. The other ends of the short suppression elbow 4 and the long suppression elbow 5 are lifted from the support beam 1 due to the overturning and abut against the bottom surface of the car body frame 2. The car body frame 2, the hinge 3 and the short suppression elbow 4 and / or the long suppression elbow 5 interact and jam, so that the hinge 3 on the side wall of the lifting side of the car body frame 2 maintains the closed state when the self-unloading vehicle is not overturned, and further makes the side wall on this side always in a closed state, and the goods are only discharged on the opposite side, avoiding the situation that the side wall on the lifting side of the car body frame 2 is uncontrollably opened during the overturning, resulting in the scattering of the goods.

[0054] It should be noted that the car body frame 2, the short suppression elbow 4, the hinge 3, the support beam 1 and the long suppression elbow 5 are all made of metal materials with relatively high stiffness (such as high-strength alloy steel).

[0055] In this embodiment, the support beam 1 is provided to support the short restraint elbow 4, the long restraint elbow 5 and the car body frame 2 during the operation of the self-unloading truck, ensuring the smoothness of each structure during the operation of the self-unloading truck. A plurality of hinges 3 are respectively and alternately hinged on both side walls extending along the length direction of the car body frame 2. A plurality of short restraint elbows 4 and a plurality of long restraint elbows 5 are alternately hinged along the length direction of the car body frame 2, and one end of the short restraint elbow 4 and the long restraint elbow 5 is rotatably connected to the corresponding hinge 3, and the other end is lapped on the support beam 1. When tipping over, the ends of the short restraint elbow 4 and the long restraint elbow 5 on the opening side of the car body frame 2 that are rotatably connected to the hinge 3 roll upward along the hinge 3, and the hinge 3 tips over to drive the side wall on this side to open for unloading. On the lifting side of the car body frame 2, the car body frame 2, the hinge 3 and the short restraint elbow 4 and / or the long restraint elbow 5 interact to form a fixed clamping state, so that this side wall always remains in a closed state, avoiding the situation that the side wall on the lifting side of the car body frame 2 is uncontrollably opened on both sides during tipping over, resulting in the scattering of goods. Compared with the tipping device that uses a spring structure to provide support force for the side door in the related art, its structure and connection method are simple, the tipping and car body lowering processes are smooth, effectively avoiding transportation accidents caused by the complex cooperation of each structure resulting in the jamming of the door opening, leading to the tipping over of the car body or the difficulty in lowering the car body frame 2, and at the same time avoiding the situation of the bilateral opening of the car body caused by insufficient support force of the spring during long-term use, effectively improving the safety and transportation efficiency of goods transportation.

[0056] Optionally, the car body frame 2 includes cross beams 21 and longitudinal beams 22;

[0057] A plurality of the cross beams 21 are arranged at intervals along the length direction of the car body frame 2, and the extending direction of the cross beams 21 is the same as the width direction of the car body frame 2;

[0058] A plurality of the longitudinal beams 22 are arranged at intervals along the width direction of the car body frame 2, and the extending direction of the longitudinal beams 22 is the same as the length direction of the car body frame 2;

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

[0060] Specifically, the car body frame 2 is composed of cross beams 21 and longitudinal beams 22 that are connected to each other. For example, the cross beams 21 and the longitudinal beams 22 form a network structure as shown in Figure 3 . The cross beams 21 and the longitudinal beams 22 can be box beams. It should be noted that in order to prevent goods from leaking through the gaps, structures such as steel plates will be provided on the car body frame 2 to form a closed box-type loading car body structure with the side walls connected to the hinges 3 around. The hinge 3 is hinged between any two adjacent cross beams 21 and is arranged at the end of the cross beam 21.

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

[0062] The upper folding page 31 is arranged on the side wall of the car body underframe;

[0063] The cross-section of the lower folding page 32 is C-shaped in the vertical direction, and a protruding part 321 is arranged on the inner arc surface of the lower folding page 32. The protruding part 321 is hinged to the car body underframe 2, and one ends of the short restraint elbow 4 and the long restraint elbow 5 are rollingly connected to the inner arc surface.

[0064] Specifically, the folding page 3 includes an upper folding page 31 and a lower folding page 32. As Figure 1 , Figure 2 , Figures 4 to 7 shown, the cross-section of the lower folding page 32 is C-shaped in the vertical direction. One ends of the short restraint elbow 4 and the long restraint elbow 5 are rollingly connected to the inner arc surface, and a protruding part 321 is arranged on the inner arc surface. Through the protruding part 321, the car body underframe 2 is hinged to the short restraint elbow 4 and the long restraint elbow 5. It should be noted that in order to prevent the short restraint elbow 4 and the long restraint elbow 5 from slipping out when rolling on the inner arc surface of the lower folding page 32, limit blocks can also be arranged at both ends of the inner arc surface.

[0065] The upper folding page 31 is used to connect with the two side walls extending along the length direction of the car body underframe 2 and is connected to the top of the lower folding page 32. One ends of the short restraint elbow 4 and the long restraint elbow 5 roll on the inner arc surface of the lower folding page 32 and cooperate with each other to drive the side walls to open and close, so as to realize the storage, transportation and dumping of materials, and avoid the problem that the vehicle overturns due to the complex connection structure in the related technology resulting in the door jamming.

[0066] It should be noted that the included angle between the protruding part 321 and the inner arc surface is an acute angle structure. When the car body underframe 2 tilts to this side, the ends of the short restraint elbow 4 and the long restraint elbow 5 on this side that are rollingly connected to the inner arc surface will directly roll to the position between the protruding part 321 and the inner arc surface according to the shape of the inner arc surface, and the lower folding page 32 will turn over, driving the upper folding page 31 to turn over. As Figure 4 and Figure 6 shown, when the ends of the short restraint elbow 4 and the long restraint elbow 5 that are rollingly connected to the inner arc surface directly roll to the position between the protruding part 321 and the inner arc surface according to the shape of the inner arc surface, the included angle between the car body underframe 2 and the horizontal plane can be 35°, so that the side wall connected to the upper folding page 31 can be quickly opened to a position where the goods can be dumped, realizing early door opening during the overturning process of the car body underframe 2, that is, realizing early unloading, and preventing the vehicle from tipping over due to uneven load caused by the goods tilting in the same direction. Then, due to the weight change on the car body underframe 2 caused by the dumping of the goods, or when the cylinder pushes the car body underframe 2 to rise to the maximum height on one side, as Figure 5 shown, the included angle between the car body underframe 2 and the horizontal plane can be 45°.

[0067] Optionally, through holes 6 are respectively formed in the short restraining elbow 4 and the long restraining elbow 5, and the through holes 6 are configured to allow the lower folding page 32 to pass through, so as to realize the mutual cooperation between the short restraining elbow 4 and the long restraining elbow 5 and the lower folding page 32.

[0068] Optionally, limiting members 211 are respectively arranged between any two adjacent cross beams 21. After passing through the through hole 6, the lower folding page 32 is used to abut against the limiting member 211, so that the plane where the upper folding page 31 is located is in the same plane as the upper end surface of the carriage chassis 2. While ensuring that the goods can be smoothly discharged through the upper folding page 31, it is avoided that the parts where the short restraining elbow 4 and the long restraining elbow 5 are connected to the inner arc surface of the lower folding page 31 are forced to break out of the lower folding page 31, ensuring the normal operation of the tipping device.

[0069] Optionally, when the carriage chassis 2 is not tipped over, the upper folding page 31 is perpendicular to the carriage chassis 2.

[0070] Specifically, in the related art, the side view cross-sectional shape of the self-unloading vehicle is usually a trapezoidal structure that is wider at the top and narrower at the bottom. However, if the carriage of this shape is used to transport goods, during the transportation process, the goods will continuously exert a large pressure on the side wall or the upper part of the side door, causing the spring structure connected to the side door through the restraining elbow to always be in a state of relatively large tension, which easily leads to insufficient supporting force of the spring structure, and then leads to the uncontrolled opening of the side door, resulting in a transportation accident. Therefore, in this embodiment, the upper folding page 31 is perpendicularly arranged with the carriage chassis 2, so that the side wall is perpendicularly arranged with the carriage chassis 2, reducing the pressure of the goods on the side wall, and further reducing the pressure on the restraining elbow, preventing the problem of uncontrolled opening caused by the failure of closing.

[0071] Optionally, the short restraining elbow 4 includes a first short main body 41 and a second short main body 42 that are connected to each other, and an obtuse angle is formed between the first short main body 41 and the second short main body 42. The second short main body 42 is used to overlap on the support beam 1, and a first roller 43 is arranged at one end of the first short main body 41 away from the second short main body 42 for rolling along the inner arc surface.

[0072] Specifically, an obtuse angle is formed between the first short main body 41 and the second short main body 42 in the short restraining elbow 4, so that there is a certain distance difference in the vertical direction between the opposite ends of the first short main body 41 and the second short main body 42, which is convenient for the design and installation of the folding page 3. And the second short main body 42 overlaps on the support beam 1 to ensure the stability of the tipping device. A first roller 43 is arranged at one end of the first short main body 41 away from the second short main body 42 for rolling along the inner arc surface of the lower folding page 31, thereby ensuring the smoothness of the opening and closing of the side wall.

[0073] Optionally, the long restraining elbow 5 includes a first long body 51 and a second long body 52 which are connected to each other, and an obtuse angle is formed between the first long body 51 and the second long body 52. The second long body 52 is used for lapping on the support beam 1, and a second roller 53 is arranged at one 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 restraining elbow 5 are the same as those of the short restraining elbow 4, and will not be elaborated here again.

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

[0076] Specifically, as Figure 7 shown, dividing the flap 3 into the upper flap 31 and the lower flap 32 for separate casting and welding can reduce the proportion of the casting, thereby reducing the weight of the flap 3 and further reducing the weight of the whole vehicle. Due to the axle weight limit of the railway track, it can avoid affecting the cargo transportation efficiency due to the excessive self-weight of the tipping device.

[0077] A self-unloading vehicle provided by an embodiment of the present invention includes the self-unloading vehicle tipping device as described above.

[0078] The beneficial effects of the self-unloading vehicle of this embodiment compared with the prior art are the same as those of the above-mentioned self-unloading vehicle tipping device, and will not be elaborated here.

[0079] Although the present invention is disclosed as above, the protection scope of the present invention 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 these changes and modifications will all fall within the protection scope of the present invention.
