[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0026] Combine 1 to Figure 3 As shown, the present invention provides a hydraulic tipping car system for ladle maintenance, including a rail car 1 and a tipping device 2, the tipping device 2 is located at the left and right ends of the rail car 1, the tipping device 2 includes a turning frame 21 and a rack hydraulic cylinder 22, the rack hydraulic cylinder 22 is installed on the rail car 1, and the output end of the rack hydraulic cylinder 22 is drive-connected to the turning frame 21 to realize the rotation of the turning frame 21, and the turning frame 21 is used to be connected to the ladle 10, and the rail car 1 is used to move toward the dust removal chamber.

[0027] Specifically, the X-axis is the left and right direction of the rail car 1. The left and right ends of the rail car 1 are respectively equipped with support seats. The tilting device 2 is located at the left and right ends of the rail car 1 and is connected to the rail car 1 through connection structures such as brackets and mounting seats. The tilting device 2 includes a turning frame 21 and a rack hydraulic cylinder 22. The rack hydraulic cylinder 22 includes a gear rack. The rack of the rack hydraulic cylinder 22 drives the gear to rotate through hydraulic power. Taking the tilting device 2 located at the right end of the rail car 1 as an example, the rack hydraulic cylinder 22 is assembled on the rail car 1, and the gear of the rack hydraulic cylinder 22 is drivingly connected to the turning frame 21. A notch is set on the turning frame 21, and the notch is connected to the ear shaft of the ladle 10. The rail car 1 is used to move toward the dust removal chamber. During maintenance, the rail car 1 is stopped near the hoisting position of the ladle 10, and then the overhead crane hoists the ladle 10 onto the turning frame 21. After the two turning frames 21 are respectively connected to the ear shafts of the ladle 10, the overhead crane is restored, and the rail car 1 moves from the hoisting position of the ladle 10 toward the dust removal chamber, and after moving to the maintenance position in the dust removal chamber, the rack hydraulic cylinder 22 drives the turning frame 21 to rotate, and the turning frame 21 drives the ladle 10 to rotate, so that the sliding water inlet at the bottom of the ladle 10 is turned out, so that the maintenance personnel can perform maintenance. For example, the rack hydraulic cylinder 22 drives the ladle 10 to rotate forward 90° through the turning frame 21 and then stops. The maintenance personnel can inspect the sliding water inlet at the bottom of the ladle 10 from the front of the ladle 10. Optionally, the rack hydraulic cylinder 22 can also be replaced by a motor, a hydraulic motor, a common hydraulic cylinder, etc. according to actual needs.

[0028] Therefore, in the present embodiment, the tilting device 2 is located at the left and right ends of the rail car 1, and the turning frame 21 of the tilting device 2 is connected to the ladle 10, so that the rail car 1 can carry the ladle 10 through the turning frame 21 to ensure the stability of the ladle 10, and the rack hydraulic cylinder 22 of the tilting device 2 realizes the rotation of the turning frame 21 through the turning frame 21, so that the sliding water outlet at the bottom of the ladle 10 is rotated out from the bottom of the ladle 10, and then moved toward the dust removal chamber by the rail car 1. In this way, during maintenance, the ladle 10 can be directly transported to the maintenance position in the dust removal chamber for maintenance by the movement of the rail car 1, and the turning of the ladle 10 within 0-180° can be realized in combination with the tilting device 2 to improve the maintenance efficiency of the ladle 10.

[0029] Optionally, combined Figure 1 and Figure 5 As shown, the tilting device 2 also includes an ear shaft locking device 23, which is installed on the turning frame 21 and includes a telescopic part, which is used to clamp with the ear shaft of the ladle 10, wherein two ear shaft locking devices 23 are provided corresponding to the ear shaft of the ladle 10.

[0030] Specifically, the trunnion locking device 23 includes a locking block 231 and a locking hydraulic cylinder 232. The locking hydraulic cylinder 232 is installed on the turning frame 21. The locking block 231 is connected to the locking hydraulic cylinder 232 through a pin. The telescopic part of the trunnion locking device 23 is the locking block 231. The locking hydraulic cylinder 232 drives the locking block 231 to telescopically move. When the turning frame 21 is connected to the ladle 10, the two locking blocks 231 are extended toward each other under the drive of the corresponding locking hydraulic cylinder 232 until they are both engaged with the trunnions of the ladle 10.

[0031] In this way, the ear shaft locking device 23 is installed on the turning frame 21 and includes a telescopic part, which is used to clamp with the ear shaft. In this way, the clamping of the telescopic part and the ear shaft prevents the ear shaft from rotating relative to the turning frame 21, thereby ensuring that the turning frame 21 and the ladle 10 rotate synchronously, thereby improving the safety of the maintenance of the ladle 10.

[0032] Optionally, combined Figure 1 and Figure 4 As shown, the ladle maintenance hydraulic tipping car system also includes a tipping locking device 3 installed on the rail car 1, and the tipping locking device 3 includes a hydraulic cylinder 31 and a safety pin 32 installed at the output end of the hydraulic cylinder 31, and the hydraulic cylinder 31 is used to drive the safety pin 32 to plug into the turning frame 21.

[0033] Specifically, a bracket is provided on the rail car 1, and a hydraulic cylinder 31 is assembled on the bracket, and the output end of the hydraulic cylinder 31 is drivingly connected to the safety pin 32 to realize the telescopic movement of the safety pin 32, and when the turning frame 21 is connected to the ladle 10, the hydraulic cylinder 31 is used to drive the safety pin 32 to plug into the turning frame 21.

[0034] In this way, the telescopic movement of the safety pin 32 is realized by the hydraulic cylinder 31 installed on the rail car 1 and the safety pin 32 installed at the output end of the hydraulic cylinder 31, and the hydraulic cylinder 31 is used to drive the safety pin 32 to plug into the turning frame 21. In this way, when the rail car 1 transports the ladle 10 to the dust removal room for inspection and maintenance, the plugging of the safety pin 32 and the turning frame 21 can avoid the accidental start-up of the rack hydraulic cylinder 22 causing the ladle 10 to flip prematurely, thereby improving the stability of the ladle 10 during transportation.

[0035] Optionally, combined Figure 2 As shown, the ladle maintenance hydraulic tipping car system further comprises two parallel heavy rails 4 , and the rail car 1 is arranged on the two heavy rails for movement along the extension direction of the two heavy rails 4 .

[0036] Specifically, two heavy rails 4 are laid on the ground through sleepers, and the running part of the rail vehicle 1 is in rolling contact with the two heavy rails 4 respectively, and the rail vehicle 1 moves along the extension direction of the two heavy rails 4 and is set on the two heavy rails.

[0037] In this way, by moving the rail vehicle 1 along the extension direction of the two heavy rails 4 and being disposed on the two heavy rails, the two heavy rails 4 can guide the movement of the rail vehicle 1 to ensure the stable movement of the rail vehicle 1 .

[0038] Optionally, the gauge between the two heavy rails 4 is used to adjust according to the size of the ladle 10 .

[0039] Specifically, the size of the ladle 10 can be understood as the volume of the ladle 10. When the volume of the ladle 10 is large, the size of the ladle 10 is relatively large, and the center of gravity of the ladle 10 is high. In order to ensure the smooth transportation of the ladle 10, the track gauge between the two heavy rails 4 needs to be increased. On the contrary, the track gauge between the two heavy rails 4 is reduced. Of course, when the track gauge between the two heavy rails 4 changes, the walking part of the rail car 1 also needs to be adaptively adjusted.

[0040] In this way, the track gauge between the two heavy rails 4 is used to adjust according to the size of the ladle 10, so that the two heavy rails 4 can meet the transportation of ladles 10 of different sizes, thereby improving the flexibility of use of the hydraulic tipping car system for ladle maintenance.

[0041] Optionally, the rail vehicle 1 includes a variable frequency speed regulation system, which is used to regulate the moving speed of the rail vehicle 1. In this way, by using the variable frequency speed regulation system to regulate the moving speed of the rail vehicle 1, the rail vehicle 1 can be moved quickly, saving transportation time and improving efficiency.

[0042] Optionally, the tilting device 2 further includes a tilting detection structure, which is installed on the rack hydraulic cylinder 22 and is used to feed back the rotation angle of the overturning frame 21 .

[0043] Specifically, the tipping detection structure can be an electronic control system composed of a displacement sensor, or it can be an electronic control system composed of an encoder. Taking the electronic control system in which the tipping detection structure is composed of an encoder as an example, the rotation angle of the tipping frame 21 is the rotation angle of the output end of the rack hydraulic cylinder 22. The encoder is installed on the rack hydraulic cylinder 22. The encoder can convert the rotation angle of the output end of the rack hydraulic cylinder 22 into an electrical signal, and feed it back to the maintenance personnel through the control system, so that the maintenance personnel can obtain the current rotation angle of the tipping frame 21, thereby facilitating the regulation of the rack hydraulic cylinder 22.

[0044] In this way, the tipping detection structure is installed on the rack hydraulic cylinder 22 and is used to feedback the rotation angle of the tipping frame 21 , so that maintenance personnel can intuitively judge the rotation angle of the tipping frame 21 to facilitate control of the rack hydraulic cylinder 22 .

[0045] Optionally, the ladle maintenance hydraulic tipping car system also includes a hydraulic station, which is welded on the rail car 1 through a mounting seat to provide hydraulic power to the rack hydraulic cylinder 22.

[0046] Specifically, the mounting seat is a casting, the hydraulic station is assembled on the top of the mounting seat, the bottom end of the mounting seat is welded to the rail car 1, and provides hydraulic power to the rack hydraulic cylinder 22, and further, the hydraulic station can also provide hydraulic power to the hydraulic cylinder in the ear shaft locking device 23 and the hydraulic cylinder 31 in the tilting locking device 3.

[0047] In this way, the hydraulic station is welded to the rail vehicle 1 through the mounting seat to provide hydraulic power to the rack hydraulic cylinder 22, so that the hydraulic station moves with the rail vehicle 1, thereby facilitating the rack hydraulic cylinder 22 to obtain stable hydraulic power.

[0048] Optionally, combined Figure 1 As shown, the ladle maintenance hydraulic tipping car system also includes a cable drum 5, which is used to supply power to the rail car 1.

[0049] Specifically, the cable drum 5 is located on the ground, and is connected to the motor of the rail vehicle 1 through a wire, and can supply power to the motor of the rail vehicle 1, and can also supply power to the electric maintenance trolley 6 described later. Optionally, an argon gas drum may also be included.

[0050] In this way, the cable drum 5 is used to supply power to the rail vehicle 1, ensuring that the rail vehicle 1 continuously obtains power, thereby ensuring the stable driving of the rail vehicle 1.

[0051] Optionally, combined Figure 2 As shown, the ladle maintenance hydraulic tipping car system also includes an electric maintenance trolley 6 for maintenance personnel to stand on. The electric maintenance trolley 6 is movably installed on the rail car 1. When the turning frame 21 is turned to the maintenance position by the rack hydraulic cylinder 22, the electric maintenance trolley 6 moves toward the turning frame 21.

[0052] Specifically, the electric maintenance trolley 6 can be a flatbed car and is equipped with a corresponding electric control system. When inspecting the bottom of the ladle 10, the bottom of the ladle 10 is at a higher position due to the rotation of the ladle 10, which affects the maintenance efficiency of the maintenance personnel. Based on this, the electric maintenance trolley 6 is movably installed on the rail car 1. When the turning frame 21 is turned to the maintenance position by the rack hydraulic cylinder 22, the electric maintenance trolley 6 is moved toward the turning frame 21 through the electric control system. Furthermore, the electric maintenance trolley 6 can be equipped with a maintenance hydraulic cylinder, and the output end of the maintenance hydraulic cylinder is pre-processed so that the output end of the maintenance hydraulic cylinder can be extended into the water inlet at the bottom of the ladle 10 for easy maintenance.

[0053] In this way, the electric maintenance trolley 6 for maintenance personnel to stand is moved and installed on the rail car 1. When the tilting frame 21 is tilted to the maintenance position by the rack hydraulic cylinder 22, the electric maintenance trolley 6 moves toward the tilting frame 21. The electric maintenance trolley 6 raises the position of the maintenance personnel on the rail car 1 to facilitate maintenance by the maintenance personnel.

[0054] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
