[0035] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0036] The ladle car is located under the steelmaking converter and is used to hold the molten liquid steel. During the smelting process, the steelmaking converter will produce a violent smelting reaction, which usually causes the slag to splash onto the rails of the ladle car, causing the ladle car to derail during the movement.

[0037] However, it is very difficult to deal with the derailment of ladle cars. Currently, a large-tonnage jack is usually used to lift the ladle car, and then the wheels of the ladle car are slowly moved above the track and then the ladle car is placed on the track. During this process, the operators work at a close distance from the ladle car, which poses a great safety hazard and has low operating efficiency, which has a great impact on the current fast-paced production.

[0038] Based on the above problems, the present invention provides a ladle car resetting device, which is applied to the steelmaking field. It can quickly and safely reset the derailed ladle car, ensure the continuity of production and the personal safety of operators, and improve production efficiency.

[0039] See also Figure 1The ladle car resetting device 10 includes a lifting member 100, a resetting mechanism 200, a moving mechanism 300, a locking mechanism 400 and a hydraulic control mechanism 500, wherein the lifting member 100, the resetting structure, the locking mechanism 400 and the hydraulic control mechanism 500 are all arranged on the moving mechanism 300, and the moving mechanism 300 is arranged on the track 30 of the ladle car 20, and is used to drive the lifting member 100, the resetting structure, the locking mechanism 400 and the hydraulic control mechanism 500 to move along the extension direction of the track 30 of the ladle car 20, so that the ladle car resetting device 10 can be quickly moved to the position where the ladle car 20 is derailed, thereby improving the maneuverability of the ladle car resetting device 10; the lifting member 100 is arranged on the resetting mechanism 200, and the resetting mechanism 200 is located at one end of the moving mechanism 300. The lifting member 100 is used to drive the ladle car 20 to rise or fall, and the resetting mechanism 200 is used to drive the lifting member 100 to move in a direction perpendicular to the extension of the track 30 of the ladle car 20, so that the lifting member 100 drives one end of the ladle car 20 to rise, and the reset mechanism 200 drives one end of the ladle car 20 to move in a direction perpendicular to the track 30, so that the rollers of the ladle car 20 correspond to the track 30, and then the lifting member 100 drives one end of the ladle car 20 to descend, so that the rollers are embedded in the track 30, thereby realizing the rapid reset of the ladle car 20, ensuring the continuity of production, and improving production efficiency and safety; the locking mechanism 400 is used to lock and fix the moving mechanism 300 during the reset process of the ladle car 20, so as to improve the stability of the ladle car reset device 10; the hydraulic control mechanism 500 is used to provide power for the lifting member 100, the reset mechanism 200, the moving mechanism 300 and the locking mechanism 400.

[0040] Optionally, the lifting member 100 may be a lifting hydraulic cylinder. It is understandable that there may be two lifting members 100, which are respectively used to lift one end of the ladle car 20 that has derailed and the two sides corresponding to the rollers of the ladle car 20, thereby improving the lifting stability.

[0041] For further information, see Figure 2 and Figure 3 The reset mechanism 200 includes a first driving member 210 , a transmission rod 220 , a slider 230 and a slide rail 240 .

[0042] The slider 230 is disposed on the transmission rod 220 , the lifting member 100 is disposed on the slider 230 , and the first driving member 210 is connected to the transmission rod 220 .

[0043] In this embodiment, the first driving member 210 is arranged at one end of the transmission rod 220, and the transmission rod 220 can be movably arranged on the base and extend in a direction perpendicular to the extension direction of the track 30. The transmission rod 220 can be driven to move by the first driving member 210 to drive the slider 230 to move in a direction perpendicular to the extension direction of the track 30 of the ladle car 20, so that when the jacking member 100 lifts the ladle car 20, the derailed end of the ladle car 20 is driven to move in a direction perpendicular to the track 30, and the derailed roller of the ladle car 20 corresponds to the upper side of the track 30, thereby realizing the resetting action of the derailed ladle car 20.

[0044] It is understandable that the first driving member 210 can be a telescopic cylinder to drive the transmission rod 220 to telescopically move in the direction perpendicular to the rail, thereby driving the lifting member 100 to move; of course, the first driving member 210 can also be a rotary motor, and the transmission rod 220 and the slider 230 can be a screw combination.

[0045] Furthermore, the slide rail 240 defines a mounting groove 241 , and the transmission rod 220 is disposed in the mounting groove 241 .

[0046] In this embodiment, the transmission rod 220 is a lead screw, and the first driving member 210 is a hydraulic motor; the transmission rod 220 is installed in the mounting groove 241 of the slide rail 240, and bearings are provided at both ends of the transmission rod 220 located in the mounting groove 241, and one end of the transmission rod 220 is connected to the output end of the first driving member 210.

[0047] In this embodiment, a screw groove cooperating with the transmission rod 220 is provided at the bottom of the slider 230. Under the drive of the first driving member 210 and the limiting action of the slide rail 240, the transmission rod 220 rotates and the slider 230 moves along the extension of the transmission rod 220 as the transmission rod 220 rotates, thereby achieving the purpose of moving the lifting member 100 arranged on the slider 230 following the movement of the slider 230, thereby achieving the purpose of moving the ladle car 20.

[0048] Specifically, the number of the sliding blocks 230 may be two, and the two lifting members 100 are respectively disposed on the two sliding blocks 230 .

[0049] It should be noted that the moving mechanism 300 includes a support member 310, and the slide rail 240 is arranged on the support member 310. The slide rail 240 can be integrally formed with the support member 310, or a mounting groove 241 can be directly opened on the support member 310 to serve as the slide rail 240 of the reset mechanism 200. No specific limitation is made here.

[0050] Furthermore, the moving mechanism 300 includes a support member 310 , a roller 320 and a second driving member 340 . The roller 320 and the second driving member 340 are both disposed on the support member 310 .

[0051] In this embodiment, the support member 310 can be regarded as a trolley frame of the ladle car resetting device 10, and the lifting member 100, the resetting structure, the locking mechanism 400 and the hydraulic control mechanism 500 are all installed on the support member 310. In addition, a roller 320 and a second driving member 340 are arranged on the support member 310, so that the second driving member 340 drives the roller 320 to move along the direction in which the track 30 of the ladle car 20 extends; in addition, the locking mechanism 400 is arranged at the roller 320.

[0052] For further information, see Figure 4 The locking mechanism 400 includes a clamping member 410 , an elastic member 420 , a third driving member 430 , and a sliding member 440 .

[0054] In this embodiment, a roller bracket 330 is disposed outside the roller 320, one end of the clamping member 410 is rotatably connected to the roller bracket 330, and the other end is used to abut against the side wall of the track 30, and the elastic member 420 is disposed between the roller bracket 330 and the clamping member 410, and is used to provide an elastic force for one end of the clamping member 410 to be away from the side wall of the track 30. The third driving member 430 is disposed on the top of the roller bracket 330 and is connected to the sliding member 440. It can be understood that the number of the clamping members 410 is two, and the two clamping members 410 are used to abut against the two side walls of the track 30 respectively.

[0055] In this embodiment, under the driving action of the third driving member 430, the sliding member 440 moves vertically downward so that the sliding member 440 is sleeved outside the end where the clamping member 410 is connected to the roller bracket 330, so that the side wall of the sliding member 440 abuts against the end where the clamping member 410 is connected to the roller bracket 330, so that the clamping member 410 compresses the elastic member 420 and makes the other end of the clamping member 410 tightly abut against the side wall of the track 30 of the ladle car 20, thereby locking and fixing the moving mechanism 300 to ensure that the lifting member 100 and the resetting mechanism 200 remain in a stable state during the process of resetting the ladle car 20, and avoid shaking of the moving mechanism 300 in the extension direction of the track 30 or in the direction perpendicular to the track 30.

[0056] Similarly, under the driving action of the third driving member 430, the sliding member 440 moves vertically upward to disengage the sliding member 440 from the clamping member 410, and the clamping member 410 is moved away from the side wall of the track 30 of the ladle car 20 under the action of the elastic restoring force of the elastic member 420, thereby achieving unlocking. In this state, the moving mechanism 300 can move freely.

[0057] Furthermore, the hydraulic control mechanism 500 includes an oil tank 510 and a hydraulic pump (not shown) and a hydraulic oil circuit block 520 arranged in the oil tank 510.
