[0033] 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.

[0034] As mentioned in the background art, during the production process of the continuous casting machine, the track guide wheel 190 is usually replaced according to different casting billets. The existing guide wheel 190 is mostly replaced manually by the staff, which has the problems of high labor intensity and low operation efficiency.

[0035] Please refer to Figure 1 The continuous casting machine roller guide wheel replacement system 100 provided in the embodiment of the present invention can solve the above-mentioned problem, which will be described in detail below.

[0036] The continuous casting machine roller guide wheel replacement system 100 includes a guide wheel storage rack 110, a guide wheel transport vehicle 120 and a guide wheel hoist 130; wherein the guide wheel storage rack 110 is used to vertically store the guide wheel 190, and to open both ends of the fixing hole 191 of the guide wheel 190, the guide wheel transport vehicle 120 is used to vertically transport the guide wheel 190 from the guide wheel storage rack 110, and to open both ends of the hoisting hole 192 of the guide wheel 190, and the guide wheel hoist 130 is used to hoist the guide wheel 190 from the guide wheel transport vehicle 120 to the roller.

[0037] When replacing the guide wheel 190, the staff can operate the guide wheel transporter 120 to take the guide wheel 190 out from the guide wheel storage rack 110, and then operate the guide wheel hoist 130 to hoist the guide wheel 190 to the roller table for replacement, so that the guide wheel 190 replacement operation can be carried out semi-automatically, reducing the labor intensity of the staff and improving the operation efficiency.

[0038] It is worth noting that, whether the guide wheel 190 is located on the guide wheel storage rack 110 or on the guide wheel transport vehicle 120, it is kept in a vertical placement posture. The vertical posture can be understood as the axial direction of the guide wheel 190 is perpendicular to the height direction, one of the radial directions of the guide wheel 190 is parallel to the height direction, and one of the radial directions is parallel to the horizontal direction. The vertical posture is convenient for exposing the ends of the fixing hole 191 and the lifting hole 192 on the guide wheel 190, and thus facilitates the coordination with the guide wheel transport vehicle 120 and the guide wheel hoist 130.

[0039] Furthermore, the fixing hole 191 is located at the center of the guide wheel 190, and the hoisting hole 192 is located on the upper side of the center of the guide wheel 190. The fixing hole 191 and the hoisting hole 192 can be completely set through the guide wheel 190, or can extend from both sides of the guide wheel 190 toward the center of the guide wheel 190 but not completely connected.

[0040] Please refer to Figure 1 The guide wheel storage rack 110 is provided with at least two support platforms 111 from top to bottom, and the support platforms 111 are used to carry the guide wheels 190. Of course, if conditions permit, the support platforms 111 on a single guide wheel storage rack 110 can be as many as possible, so as to place multiple guide wheels 190 at the same time, so as to facilitate the guide wheel transport vehicle 120 to transport the guide wheels 190 in an orderly manner.

[0041] Please refer to Figure 2 and Figure 3 The guide wheel transport vehicle 120 includes a vehicle body 121, a counterweight block 122 and a transport fork rod 123. The counterweight block 122 and the transport fork rod 123 are respectively arranged at the rear end and the front end of the vehicle body 121. The transport fork rod 123 is used to cooperate with the guide wheel 190 through the fixing hole 191.

[0042] During operation, the vehicle body 121 is used to act as a walking carrier, and four rollers or two walking tracks may be installed at the bottom. The counterweight 122 is used to act as a balance at the rear end of the vehicle body 121 to prevent the vehicle body 121 from being unbalanced front and rear after carrying the guide wheel 190, and the carrying fork 123 is used to partially extend into the fixing hole 191 to carry and move the entire guide wheel 190.

[0043] Specifically, the transport fork rod 123 includes a fork frame 1231 and a fixed rod 1232 connected to each other. The rear end of the fork frame 1231 is connected to the vehicle body 121, and two forked portions 1233 are formed at the front end of the fork frame 1231. The fixed rod 1232 is used to simultaneously penetrate the two forked portions 1233 and the guide wheel 190.

[0044] When preparing to transport the guide wheel 190, the two forked portions 1233 can drive the fixing rod 1232 to move to a position aligned with the fixing hole 191, and then move the fixing rod 1232 to simultaneously pass through the two forked portions 1233 and the fixing hole 191, thereby facilitating the guide wheel 190 to be transported and moved.

[0045] It is worth noting that in order to prevent the guide wheel 190 from falling off the fixing rod 1232, or to prevent the fixing rod 1232 from detaching from the fork portion 1233, the transport fork rod 123 may further include two limit members 1234, and the two limit members 1234 are both sleeved on the fixing rod 1232 and are respectively located on the side of the two forks 1233 away from each other.

[0046] In this embodiment, the fixing rod 1232 can be a stud or an optical axis, and the limiting member 1234 can be a nut or a sleeve.

[0047] Please refer to Figure 2 and Figure 3 In order to improve the use flexibility of the transport fork rod 123 and facilitate the transport of the guide wheels 190 at different heights, the guide wheel transport vehicle 120 may further include a lifting mechanism 124, the bottom end of the lifting mechanism 124 is connected to the vehicle body 121, and the end of the transport fork rod 123 away from the guide wheel 190 is connected to the top of the lifting mechanism 124. Specifically, the rear end of the fork frame 1231 is connected to the lifting mechanism 124.

[0048] In this embodiment, the lifting mechanism 124 is preferably a lifting electric cylinder; in other embodiments of the present invention, the lifting mechanism 124 may also be a lifting air cylinder or a lifting hydraulic cylinder, and there is no limitation on its specific power form.

[0049] Please refer to Figure 2 and Figure 3 In order to facilitate the staff to apply force to drive the guide wheel transport vehicle 120 to move, the guide wheel transport vehicle 120 may further include a handle 125, which is disposed at the rear end of the vehicle body 121 and is higher than the counterweight block 122.

[0050] In this embodiment, there are two handles 125, which are respectively connected to the two sides of the rear end of the vehicle body 121, so that the staff can hold the two handles 125 with both hands. Of course, in other embodiments of the present invention, the number of handles 125 can also be one or three, so that one or two staff members can jointly apply force to the vehicle body 121. In addition, the handles 125 can also be U-shaped or C-shaped, and there is no limitation on their specific appearance.

[0051] Please refer to Figure 1 and Figure 4 The guide wheel hoist 130 includes a hoisting frame 131, a hoisting hook 132, a hoisting rope 133 and two hoisting rods 134 connected in sequence. The two hoisting rods 134 are arranged at intervals and are respectively used to cooperate with the two ends of the hoisting hole 192.

[0052] When the guide wheel 190 is hoisted, the hoisting frame 131 supports the hoisting hook 132 and guides the hoisting hook 132 to move, and the hoisting hook 132 can move along the hoisting frame 131 under the action of external force. The hoisting rope 133 is used to pull the hoisting rod 134, and the two hoisting rods 134 cooperate with the hoisting holes 192 to drive the guide wheel 190 to move during hoisting.

[0053] In the present embodiment, there are two groups of lifting hooks 132, and two groups of lifting ropes 133 are respectively arranged on the lower side of the two groups of lifting hooks 132. The group of lifting ropes 133 located on the upper side is located between the two groups of lifting hooks 132 and is in a diamond shape, and the group of lifting ropes 133 located on the lower side is in an inverted V shape. The two types of lifting ropes 133 can not only increase the lifting range of activities but also improve the lifting stability, so that the shaking of the hooks and the guide wheels 190 during the lifting process is smaller.

[0054] Please refer to Figure 1 and Figure 4 In order to realize flexible movement of the height of the guide wheel 190 during the lifting process, the guide wheel hoist 130 may further include a guide wheel 135 and a chain 136. The guide wheel 135 is in contact with the lifting rope 133. The chain 136 is wound around the guide wheel 135 and is used to adjust the height of the guide wheel 135 under the action of external force.

[0055] When the chain 136 is moved by external force, the guide wheel 135 can move up and down along the lifting rope 133 on the upper side, and simultaneously drive the diamond-shaped end of the lifting rope 133 to move up and down, thereby driving the lifting hook 132 on the lower side, another set of lifting ropes 133, the lifting rod 134 and the hoisted guide wheel 190 to move up and down.

[0056] Please refer to Figure 1 and Figure 4The guide wheel hoist 130 also includes two hoisting rings 137 arranged at intervals, the two hoisting rings 137 are connected to the hoisting rope 133, and the ends of the two hoisting rods 134 that are far away from each other are respectively connected to the two hoisting rings 137.

[0057] Specifically, the two lifting rings 137 are respectively connected to the two bottom ends of the inverted V-shaped lifting rope 133 located on the lower side, and are used to support the two lifting rods 134, so that the two lifting rods 134 can be inserted into the lifting holes 192 to drive the guide wheel 190 to perform lifting activities.

[0058] It is worth noting that in order to further improve the installation accuracy of the guide wheel 190, a long groove can be provided on the base of the roller for installing the guide wheel 190. When the spacing between adjacent guide wheels 190 needs to be adjusted, the position of the guide wheel 190 can be adjusted along the long groove, so that the spacing between adjacent guide wheels 190 meets the use requirements. During the adjustment process, auxiliary tools can be used to measure the spacing between the guide wheels 190.

[0059] In summary, the continuous casting machine roller guide wheel replacement system 100 provided in the embodiment of the present invention has at least the following advantages: the continuous casting machine roller guide wheel replacement system 100 can make the guide wheel 190 replacement operation semi-automatic, reducing the labor intensity of the staff and improving the operation efficiency.

[0060] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
