Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail vehicle technology, and in particular to a rail for molten iron ladle cars that is easy to adjust the wheel spacing. Background Technology
[0002] Molten iron ladle cars are specialized vehicles used by metallurgical enterprises to transport molten iron from blast furnaces to steel mills, iron casting machines, and foundries for steelmaking, casting iron blocks, or casting steel ingot molds. To ensure the smooth movement of molten iron ladle cars, they are often mounted on tracks for guidance, thereby improving their stability. However, because molten iron ladle cars come with different wheel spacings, and the tracks used for ordinary molten iron ladle cars are welded to the ground, they lack flexibility and cannot adapt to guiding molten iron ladle cars with different wheel spacings, thus having significant limitations. Utility Model Content
[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a track for molten iron ladle cars that is easy to adjust the wheel distance. This solves the problem that the tracks used for ordinary molten iron ladle cars are welded to the ground, which are not flexible enough and cannot adapt to the guidance of molten iron ladle cars with different wheel distances, thus having strong limitations.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a track for molten iron ladle cars that facilitates adjustment of wheel track, comprising two tracks, two sliding holes, two sliding grooves, and a guide adjustment assembly;
[0005] The guide adjustment assembly is located inside the sliding groove. The guide adjustment assembly includes a threaded post one, a threaded sleeve, a threaded post two, a connecting post, a hole, a locking post, a locking hole, and a guide wheel. The guide wheel rolls inside the sliding groove. The locking hole is opened on the guide wheel. The connecting post rotates inside the locking hole. The hole is opened on the locking post. The connecting post rotates along the inside of the hole. The threaded post two is welded to the connecting post. There are four guide adjustment assemblies, and the four guide adjustment assemblies are respectively located inside the corresponding sliding groove.
[0006] Preferably, the two sliding grooves are respectively opened on the corresponding tracks, and the two sliding holes are respectively opened on the corresponding tracks.
[0007] Preferably, the four locking pins slide along the corresponding sliding holes, and the inner surfaces of the four threaded sleeves are threadedly connected to the surfaces of the corresponding threaded pins.
[0008] Preferably, the interior of each of the four threaded sleeves is threadedly connected to the surface of the corresponding threaded post, and the four threaded posts are respectively welded to the corresponding rollers.
[0009] Preferably, a molten iron ladle car is rotatably connected between the four rollers, and threaded holes are provided at the upper ends of the four locking posts.
[0010] Preferably, each of the four threaded holes is internally threaded with a threaded post three, and a knob is welded to the upper end of each of the four threaded posts three.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This track for molten iron ladle cars, which facilitates adjustment of wheel track, uses threaded sleeves in the guide adjustment assembly. When different wheel track sizes are required, only different sizes of threaded sleeves need to be replaced to guide molten iron ladle cars with different wheel track sizes. This compensates for the shortcomings of two tracks welded to the ground, which cannot adapt to molten iron ladle cars with different wheel track sizes, and expands the applicability of the track.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0022] Please see Figure 1-3 This utility model provides a technical solution: a track for molten iron ladle cars that facilitates adjustment of wheel track, comprising two tracks 1, two sliding holes 15, two sliding grooves 16 and a guide adjustment component;
[0023] The guide adjustment assembly is located inside the sliding groove 16. The guide adjustment assembly includes a threaded post 4, a threaded sleeve 5, a threaded post 6, a connecting post 7, a hole 8, a locking post 9, a locking hole 10, and a guide wheel 11. The guide wheel 11 rolls inside the sliding groove 16. The locking hole 10 is opened on the guide wheel 11. The connecting post 7 rotates inside the locking hole 10. The hole 8 is opened on the locking post 9. The connecting post 7 rotates along the inside of the hole 8. The threaded post 6 is welded to the connecting post 7. There are four guide adjustment assemblies, and the four guide adjustment assemblies are respectively located inside the corresponding sliding groove 16.
[0024] Two sliding grooves 16 are respectively opened on the corresponding track 1, and two sliding holes 15 are respectively opened on the corresponding track 1.
[0025] The four locking pins 9 slide along the corresponding sliding holes 15, and the inner surfaces of the four threaded sleeves 5 are threadedly connected to the surfaces of the corresponding threaded pins 6.
[0026] The interior of the four threaded sleeves 5 are respectively threaded to the surface of the corresponding threaded post 4, and the four threaded posts 4 are respectively welded to the corresponding rollers 3.
[0027] The molten iron car 2 is rotatably connected between the four rollers 3, and the upper ends of the four locking posts 9 are all provided with threaded holes 14.
[0028] Each of the four threaded holes 14 is internally threaded with a threaded post 3 13, and a knob 12 is welded to the upper end of each of the four threaded posts 3 13.
[0029] It should be noted that in the initial state, the four threaded posts 13 are in contact with the surfaces of the corresponding connecting posts 7.
[0030] When it is necessary to install molten iron ladle car 2 onto the track;
[0031] First, select a threaded sleeve 5 of appropriate size according to the distance between threaded post 4 and threaded post 6. Then, drive the threaded sleeve 5 to move by external force. The threaded sleeve 5 moves to the surface of threaded post 6. Then, continue to drive the threaded sleeve 5 to move until it can no longer move toward threaded post 6.
[0032] Secondly, the molten iron ladle car 2 is driven to move by external force. The movement of the molten iron ladle car 2 drives the four threaded cylinders 4 to move to the appropriate position. Subsequently, the threaded sleeve 5 is driven to move by external force until it connects with the surface of the threaded cylinders 4.
[0033] Finally, the knob 12 is driven to move by an external force. The movement of the knob 12 drives the threaded column 13 to move. The threaded column 13 no longer contacts the connecting column 7.
[0034] When the distance between rollers 3 needs to be adjusted and the track 1 needs to be adapted, simply replace the threaded sleeve 5 of the appropriate size to reinstall the molten iron ladle car 2 on the track 1.
[0035] By setting the threaded sleeve 5 in the guide adjustment component, when it is necessary to adapt to different wheel distances, it is only necessary to replace the threaded sleeve 5 of different sizes to guide the molten iron ladle cars with different wheel distances. This makes up for the shortcomings of the two rails 1 being welded to the ground and unable to adapt to molten iron ladle cars with different wheel distances, thus expanding the applicability of the rail.
[0036] By setting the knob 12, when it is necessary to install or remove the threaded sleeve 5, firstly, the knob 12 drives the threaded post 3 13 to contact the connecting post 7, thereby restricting the position of the connecting post 7 and avoiding the problem of the threaded sleeve 5 being difficult to remove due to the threaded post 2 6 rotating when the threaded sleeve 5 is moving. In other words, it reduces the difficulty of removing and installing the threaded sleeve 5.
[0037] Working principle:
[0038] When it is necessary to install molten iron ladle car 2 onto the track;
[0039] First, select a threaded sleeve 5 of appropriate size according to the distance between threaded post 4 and threaded post 6. Then, drive the threaded sleeve 5 to move by external force. The threaded sleeve 5 moves to the surface of threaded post 6. Then, continue to drive the threaded sleeve 5 to move until it can no longer move toward threaded post 6.
[0040] Secondly, the molten iron ladle car 2 is driven to move by external force. The movement of the molten iron ladle car 2 drives the four threaded cylinders 4 to move to the appropriate position. Subsequently, the threaded sleeve 5 is driven to move by external force until it connects with the surface of the threaded cylinders 4.
[0041] Finally, the knob 12 is driven to move by an external force. The movement of the knob 12 drives the threaded column 13 to move. The threaded column 13 no longer contacts the connecting column 7.
[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
