Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a tilting slag removal ladle car. Background Art

[0002] In the long process of steel mills, after the converter taps out steel or before the refining furnace smelts, there is a thick layer of slag on the upper layer of the ladle due to the converter smelting process. The thickness of the slag layer varies according to the smelting process, and the thickest can reach 400mm. The slag layer has a great impact on the next step.

[0003] The traditional slag removal process adopts a crane to lift the slag, and the crane auxiliary hook is hung on the tipping hook to perform dumping slag removal. The above-mentioned existing slag layer cleaning method requires frequent use of the crane during actual use, which is more troublesome and has certain risks. Therefore, in view of the above problems, a tipping slag removal ladle car is designed to better meet the actual use needs. Utility Model Content

[0004] The utility model aims to provide a tipping slag removal ladle car to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tilting slag removal ladle car, comprising a car body, a slag basin is installed on the left side of the upper end surface of the car body, a tilting base is installed on the car body, a guide frame is also fixed to the upper end surface of the car body, a tilting bag is nested and installed on the tilting base, a tilting bracket is arranged on the outside of the tilting bag, the tilting bracket is rotatably connected to the car body, one end of the tilting cylinder is rotatably connected to the tilting bracket, the other end of the tilting cylinder is rotatably connected to the car body, and a support rod arranged on the right side of the tilting bag is also fixed on the car body.

[0006] Preferably, the bearing at the lower end of the vehicle body is connected to a running wheel, and the running wheel is in contact with the guide rail for rolling, and support blocks are also fixed symmetrically front and back on the vehicle body, and the side of the support block close to the tipping bag is an inclined structure, and the support block is in contact with the tipping bag to achieve a limiting effect, through the action of the support block, support limiting can be achieved when the tipping bag tips over, thereby ensuring the stability of the tipping bag.

[0007] Preferably, the tipping base is rotatably connected to the vehicle body, and the rotation angle of the tipping base is 0-20°. By limiting the rotation angle of the tipping base, it is possible to effectively avoid the tipping base driving the tipping bag to rotate too much and causing dangerous accidents.

[0008] Preferably, the guide frame is symmetrically distributed front and rear about the center line of the vehicle body, and an arc groove is opened on the guide frame, and the center of the arc groove on the guide frame coincides with the rotation center of the tipping base and the tipping bracket. By limiting the center position of the guide frame, the normal operation of the device can be guaranteed.

[0009] Preferably, guide pillars are symmetrically fixed on the tipping bag front and back, and the guide pillars are slidably connected to the arc grooves on the guide frame. The guiding action between the guide pillars and the arc grooves on the guide frame can ensure the normal rotation of the tipping bag, and the secondary positioning support of the tipping bag can be achieved through the contact between the guide pillars and the guide frame, thereby ensuring the stability of the tipping bag.

[0010] Preferably, a buffer block is also fixed to the upper end surface of the support rod, and the buffer block is in contact with the tilting bracket to achieve a buffering and protective effect. Through the action of the buffer block, buffering and shock absorption can be achieved when the tilting bag is reset. Cooperating with the support rod to achieve the supporting effect of the tilting bag, the large impact on the tilting cylinder when the tilting bag is reset can be effectively reduced, thereby extending the service life of the tilting cylinder.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The tilting slag-removing ladle car adopts an oil cylinder to realize the tilting effect of the tilting ladle, which is convenient for the discharge of slag and reduces the operation rate of smelting cross-travel vehicles. It only needs to lift the ladle onto the tilting car once after the steel is tapped from the converter, and the remaining processes are completed on this tilting car, thereby effectively reducing the process time and fast pace. The tilting and slag-removing process can be synchronized with the walking process of the ladle car. Through the hydraulic chain plate device, the cables and hydraulic pipelines are transmitted to the tilting car body. The tilting and slag-removing can be carried out during the walking process, which saves the overall time of entering the refining furnace. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a tilting slag ladle car, comprising a car body 1, a slag basin 2 is installed on the left side of the upper end surface of the car body 1, a tilting base 3 is installed on the car body 1, a guide frame 4 is also fixed on the upper end surface of the car body 1, a tilting bag 5 is nested and installed on the tilting base 3, a tilting bracket 6 is arranged on the outer side of the tilting bag 5, the tilting bracket 6 is rotatably connected to the car body 1, one end of the tilting cylinder 7 is rotatably connected to the tilting bracket 6, and the other end of the tilting cylinder 7 is rotatably connected to the car body 1, and a support rod 8 arranged on the right side of the tilting bag 5 is also fixed on the car body 1.

[0019] The lower end bearing of the vehicle body 1 is connected with a running wheel 101, and the running wheel 101 contacts the guide rail 9 and can roll. A support block 102 is also fixed to the vehicle body 1 symmetrically in the front and rear, and the side of the support block 102 close to the tipping bag 5 is an inclined structure, and the support block 102 contacts the tipping bag 5 to achieve a limiting effect; the tipping base 3 and the vehicle body 1 are rotatably connected, and the rotation angle of the tipping base 3 is 0-20°; the guide frame 4 is symmetrically distributed in the front and rear about the center line of the vehicle body 1, and an arc groove is provided on the guide frame 4, and the center of the arc groove on the guide frame 4 coincides with the rotation center of the tipping base 3 and the tipping bracket 6; the tipping bag 5 is also symmetrically fixed with a guide column 501 in the front and rear, and the guide column 501 is connected to the arc groove on the guide frame 4 in a sliding manner;

[0020] When using the tipping slag ladle car, Figure 1-Figure 3As shown, the tipping bag 5 is hoisted and installed with the entire device by a driving vehicle, and the positioning of the tipping bag 5 can be achieved by cooperating with the nesting effect between the tipping base 3 and the tipping bag 5. The stability of the tipping bag 5 can be ensured by cooperating with the supporting and limiting effect of the tipping bracket 6. The transfer of the tipping bag 5 can be achieved by cooperating with the rolling effect between the walking wheel 101 and the guide rail 9. During the transfer process, the tipping cylinder 7 is simultaneously started to extend, and the tipping bracket 6 is driven to rotate by the tipping cylinder 7, thereby driving the tipping bag 5 to be supported. The force rotates, and the sliding action between the guide column 501 and the arc groove on the guide frame 4 can ensure the stability of the rotation of the tipping bag 5, until the guide column 501 contacts the end surface of the arc groove on the guide frame 4, thereby realizing the primary limit of the tipping bag 5. At this time, the tipping bag 5 just rotates 20°, and at this time, the tipping bag 5 just contacts the inclined surface of the support block 102, thereby realizing the secondary support of the tipping bag 5, ensuring the stability of the tipping bag 5, and making the steel slag in the tipping bag 5 dumped into the slag basin 2 to be collected for subsequent processing;

[0021] A buffer block 801 is also fixed to the upper end surface of the support rod 8, and the buffer block 801 contacts the tipping bracket 6 to achieve a buffering protection effect;

[0022] After dumping is completed, Figure 1-Figure 3 As shown, at this time, the tilting cylinder 7 is controlled to contract, so that the tilting bracket 6 is forced to drive the tilting bag 5 to reset. When the bracket 6 is reset and contacts the buffer block 801, the buffer block 801 can achieve a buffering effect, and the support rod 8 can achieve a supporting effect of the bracket 6 and the tilting bag 5, thereby avoiding the bracket 6 and the tilting bag 5 from generating a large impact force on the tilting cylinder 7 during resetting, thereby preventing the tilting cylinder 7 from being damaged, and effectively ensuring the service life of the tilting cylinder 7. This is the working principle of the tilting slag ladle car.
