Description

Technical Field

[0001] This utility model belongs to the field of metallurgical railway transportation technology, and in particular relates to a non-motorized tipping slag car. Background Technology

[0002] Based on the characteristics of steel slag handling processes in metallurgical enterprises, existing metallurgical railway slag tank cars are divided into two categories: motorized tipping slag tank cars and non-motorized tipping slag tank cars. Traditional 11-cubic-meter slag tanks are only suitable for dedicated motorized tipping slag tank cars and require overhead cranes for loading. Due to the limitations of the metallurgical enterprise's on-site environment, road-mounted tank lifters are needed at the loading point to complete the loading and unloading of 11-cubic-meter slag tanks. The "ring-shaped tank ring" on the original 11-cubic-meter motorized slag tank car body is 2.5 meters above the ground. After lifting the slag tank, the road-mounted tank lifter cannot cross the height of the "ring-shaped tank ring" to place the slag tank onto the 11-cubic-meter motorized slag tank car body. Furthermore, the traditional clearance side bearing used on the tank car bogie is a simple support block with a wear plate on the car body where it mates. When the railway freight car travels on curves, the side bearing and the friction plate on the tank car bogie generate dry friction. When the friction is high, the rotational resistance between the car body and the bogie is significant, easily causing the tank car to derail. Utility Model Content

[0003] The purpose of this invention is to provide a non-motorized tipping slag tanker to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A non-motorized tipping slag car includes a chassis, a bogie, a slag car support platform, a slag car, a coupler, and wheelsets. The chassis has a concave structure in the middle. The bogie includes side frames, a bolster, and rolling clearance side bearings. The rolling clearance side bearings include roller shafts, rollers, side bearing seats, and side bearing pads. The top center of the bolster is connected to the chassis. The slag car support platform is connected to the front and rear of the chassis. The slag car is placed between the slag car support platforms. The front and rear ends of the chassis are connected to couplers. The bottom sides of the bolster are rigidly connected to the side frames. As longitudinal support components, the axle boxes on both sides of the bottom of each side frame are slidably connected to the wheelset via bearings. A spring damping unit is connected in the middle of each side frame. Side bearing pads are placed above both ends of the bolster. The side bearing pads are made of steel plates. A side bearing seat is placed above the side bearing pads. The side bearing seat is a box-shaped structure, welded from steel plates. Symmetrical grooves are opened at the top of the steel plate along the length direction. Roller shafts are fixed side by side in the grooves. The diameter of the middle section of the roller shaft is larger than the diameter of the two ends. The roller is a hollow cylinder. The roller shaft passes through the roller and is rotatably connected to the roller.

[0005] Preferably, the slag tank support platform is a box-shaped structure welded from steel plates, including a base. First support ribs are vertically welded to both sides of the upper surface of the base. Second support ribs are vertically welded to the inner side of the first support ribs on the upper surface of the base. Third support ribs are vertically welded to the inner side of the second support ribs on the upper surface of the base. The first, second, and third support ribs are parallel to each other. Reinforcing plates are vertically welded to the outer sides of the first support ribs on both sides. All reinforcing plates are trapezoidal. First vertical plates are vertically welded between the first and second support ribs. Second vertical plates are vertically welded between the second and third support ribs. The first and second vertical plates are rectangular. The bottom edges of the reinforcing plates, first vertical plates, and second vertical plates are fixed to the base and perpendicular to the base. The first, second, and third support ribs, reinforcing plates, first vertical plates, and second vertical plates on both sides of the base are mirror-symmetrical along the middle vertical plane of the base. The height of the front end of the second support rib is lower than that of the first support rib. The first and third support ribs are identical in shape and size. A first horizontal plate is horizontally welded to the top of the second support rib between the first and third support ribs. A second horizontal plate is horizontally welded between the first and second support ribs, and between the second and third support ribs. The height of the second horizontal plate is located in the middle of the second support rib. A third horizontal plate is horizontally welded between the third support ribs on both sides, and the third horizontal plate is on the same horizontal plane as the second horizontal plate. The tops of the first and third support ribs are welded to the same top cover plate. Inclined through holes are opened on both sides of the upper surface of the top cover plate, and sheaths are welded into the through holes. The bottom of the sheath extends to the upper surface of the first horizontal plate, and a positioning block is placed inside the sheath. Reinforcing ribs are inclinedly welded to the sides of the sheath. Wear plates are welded between the sheaths on the top cover plate. A first sealing plate is vertically welded to the front end of both the first horizontal plate and the top cover plate. A second sealing plate is vertically welded to the front end and middle of both the first and second horizontal plates. A third sealing plate is vertically welded to the front end of both the third horizontal plate and the top cover plate.

[0006] Preferably, the base is connected to the base frame by high-strength bolts and fixed with nuts. A flat washer is fitted on the nut, and a spring washer is added to the flat washer to prevent the bolt or nut from loosening under vibration or dynamic load. The continuous pressure is generated through elastic deformation to increase friction.

[0007] Preferably, the side bearing includes a base plate, a baffle plate, and a side plate. The baffle plate is vertically welded above the base plate in the width direction, and the side plate is vertically welded above the base plate in the length direction. Symmetrical grooves are formed at the top of the side plate.

[0008] Preferably, the opposing surfaces of the positioning blocks are all inclined surfaces, so that the tank is accurately positioned.

[0009] Preferably, the positioning block is provided with lifting holes to facilitate the installation and replacement of the positioning block.

[0010] Preferably, the sheath is made of welded steel plates.

[0011] Preferably, a buffer unit is connected to the coupler.

[0012] Working principle: The slag tank support platform is a box-shaped structure welded from steel plates. It does not have a "ring-shaped tank ring." After the truck lifts the slag tank, it directly places it on the support platform. Positioning blocks restrict the lateral and longitudinal displacement of the slag tank on the support. The inclined surfaces of the positioning blocks are designed with slopes, allowing the tank to be guided down accurately. This avoids the problem of the original 11-cubic-meter motorized slag tank truck being unable to use a truck lift for loading due to the height and shape limitations of the "ring-shaped tank ring." The rollers in the rolling clearance side bearings can roll flexibly, effectively reducing the friction between the upper side bearing of the underframe and the lower side bearing of the bogie. The side bearing seat has a box-shaped structure, effectively supporting the rollers and improving the stability of the tank truck.

[0013] The beneficial effects achieved by this utility model are as follows: (1) By using the spring damping unit of the bogie, the vibration of the vehicle body is reduced and the safety of transportation is improved; (2) The rolling clearance of the side bearing reduces the friction between the upper side bearing of the underframe and the lower side bearing of the bogie, and at the same time reduces the rotational resistance between the underframe and the bogie when the tank car is running on a curve, preventing the tank car from tilting, making the tank car run more smoothly, and reducing the risk of derailment; the side bearing pads are flexibly placed and the side bearing clearance between the tank car underframe and the bogie can be dynamically adjusted as needed. (3) The positioning block adopts a sloping design to ensure accurate positioning of the tank. The slag tank support platform adopts a box-type structure, which facilitates the tank-carrying vehicle to place the slag tank on the slag tank support platform. (4) The base of the slag pot support platform is connected to the base frame by high-strength bolts. It is detachable, which facilitates installation and replacement and can fully ensure the accurate and reliable positioning of the slag pot. (5) The slag tanker truck meets the requirements of the tanker truck for loading and unloading, makes full use of the existing 11 cubic meter slag tank, saves enterprise costs, and makes it more convenient to unload the slag tank by crane in the steel slag processing process, thus improving work efficiency.

Detailed Implementation

[0016] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-7 As shown, a non-motorized tipping slag tanker includes a chassis 1, a bogie 2, a slag tank support platform 3, a slag tank 4, a coupler 5, and wheelsets 6. The chassis 1 has a concave structure in the middle. The bogie 2 includes side frames 201, a bolster 202, and rolling clearance side bearings 203. The rolling clearance side bearings 203 include roller shafts 2031, rollers 2032, side bearing seats 2033, and side bearing pads 2034. The top center of the bolster 202 is connected to the chassis 1. The slag tank support platform 3 is connected to the chassis 1 at the front and rear. The slag tank 4 is placed between the slag tank support platforms 3. The front and rear ends of the chassis 1 are connected to the coupler 5. The coupler 5 is connected to a buffer unit 7. The bottom two sides of the bolster 202 are rigidly connected to the side frames 201, which serve as longitudinal supports. The axle boxes on both sides of the bottom of each side frame 201 are slidably connected to the wheelsets 6 through bearings. A spring damping unit 204 is connected to the middle of each side frame 201. Side bearing pads 2034 are placed on top of both ends. The side bearing pads 2034 are made of steel plates. Side bearing seats 2033 are placed on top of the side bearing pads 2034. The side bearing seats 2033 are box-shaped structures, welded from steel plates. Symmetrical grooves are opened at the top of the steel plate along the length direction. There are 3 grooves on each side. Roller shafts 2031 are fixed side by side in the grooves. The diameter of the middle section of the roller shaft 2031 is larger than the diameter at both ends. The roller 2032 is a hollow cylinder. The roller shaft 2031 passes through the roller 2032 and is rotatably connected to the roller 2032. The roller 2032 can roll smoothly. During the transportation of the tank car, a certain amount of impact and vibration will be generated. The buffer unit connected to the coupler effectively reduces the impact energy, reduces collision and friction, and makes the tank car run stably. A rolling clearance side bearing is placed between the underframe and the bolster. The rollers of the rolling clearance side bearing reduce the rotational resistance between the underframe and the bogie when the tank car is running on a curve, preventing the tank car from tilting.

Reinforcing plates 305 are vertically welded to the outer sides of the first support ribs 302 on both sides. All reinforcing plates 305 are trapezoidal. First vertical plates 306 are vertically welded between the first support ribs 302 and the second support ribs 303. The second support ribs 303 and the... The first vertical plate 306 and the second vertical plate 307 are vertically welded between the three supporting stiffeners 304. The first vertical plate 306 and the second vertical plate 307 are rectangular. The bottom edges of the reinforcing plate 305, the first vertical plate 306 and the second vertical plate 307 are all fixed to the base 301, and the reinforcing plate 305, the first vertical plate 306 and the second vertical plate 307 are all perpendicular to the base 301. The first supporting stiffener 302, the second supporting stiffener 303, the third supporting stiffener 304, the reinforcing plate 305, the first vertical plate 306 and the second vertical plate 307 on both sides of the base 301 are mirror symmetrical along the middle vertical plane of the base 301. The height of the front end of the second supporting stiffener 303 is lower than that of the first supporting stiffener 302 and the third supporting stiffener 304. The first supporting stiffener 302 and the third supporting stiffener 304 are rectangular. The three support ribs are identical in shape and size. The third support rib 304 is thicker than the first support rib 302. The top of the second support rib 303 is located between the first support rib 302 and the third support rib 304, where a first horizontal plate 308 is horizontally welded. A second horizontal plate 309 is horizontally welded between the first support rib 302 and the second support rib 303, and between the second support rib 303 and the third support rib 304. The height of the second horizontal plate 309 is located in the middle of the second support rib 303. A third horizontal plate 310 is horizontally welded between the third support ribs 304 on both sides. The third horizontal plate 310 and the second horizontal plate 309 are located on the same horizontal plane. The tops of the first support rib 302 and the third support rib 304 are welded to the same upper cover plate 311. 11. Inclined through holes are opened on both sides of the upper surface. A sheath 312 is welded into the through holes. The sheath 312 is made of steel plate and welded together. The bottom of the sheath 312 extends to the upper surface of the first horizontal plate 308. A positioning block 313 is placed inside the sheath 312. The opposite surfaces of the positioning block 313 are all inclined. A lifting hole 323 is provided on the positioning block 313. A reinforcing rib 314 is welded inclined to the side of the sheath 312. A wear plate 315 is welded between the upper cover plate 311 and the sheath. The front ends of the first horizontal plate 308 and the upper cover plate 311 are both welded with a first sealing plate 316. The front ends and the middle of the first horizontal plate 308 and the second horizontal plate 309 are both welded with a second sealing plate 317. The front ends of the third horizontal plate 310 and the upper cover plate 311 are welded with a third sealing plate 318.The base 301 is connected to the base frame 1 by high-strength bolts 319 and fixed by nuts 320. A flat washer 321 is fitted on the nut 320, and a spring washer 322 is added to the flat washer 321. The base is fixed to the base frame with high-strength bolts for easy disassembly and maintenance. The positioning block adopts a bevel design to ensure accurate positioning of the tank. A box-shaped structure is formed by welding the first, second, and third support ribs, which allows the tanker truck to directly place the tanker on the tanker support platform after lifting it. Combined with the reinforcing plate, the first vertical plate, the second vertical plate, the first horizontal plate, the second horizontal plate, and the third horizontal plate, the structural strength of the box-shaped structure is strengthened and the stability is improved. The elastic deformation of the spring washer generates continuous pressure to increase friction and prevent the high-strength bolts or nuts from loosening under vibration or dynamic load.

[0019] A further embodiment of this utility model is as follows: Figure 14-16 As shown, the side bearing 2033 includes a base plate 8, a baffle 9 and a side plate 10. The baffle 9 is vertically welded above the width direction of the base plate 8, and the side plate 10 is vertically welded above the length direction of the base plate 8. A symmetrical groove is formed at the top of the side plate 10.

[0020] This slag car uses a self-made bogie and slag car support platform, eliminating the need for a "ring-shaped tank ring." After the road-mounted tanker lifts the slag car, it is directly placed on the slag car support platform, eliminating the need to purchase new slag car and making full use of the existing 11-cubic-meter slag car, thus saving on construction costs for the company. Through dynamic performance calculations of railway tank car design, the maximum derailment coefficient under heavy-duty mining conditions using traditional clearance side bearings is 0.816; after adopting rolling clearance side bearings, the maximum derailment coefficient under heavy-duty mining conditions is 0.517, effectively reducing it by 37%. The tank car runs more smoothly, reducing the risk of derailment.
