[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0043] It should be noted that all the directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly

[0044] In the present invention, unless otherwise clearly specified or limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0045] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" can explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] In the related art, when replacing a bending roll block, a replacement device is needed. The replacement device is pushed into the window of the rolling mill. The hydraulic cylinder in the replacement device can support the removed bending roll block, and then the replacement device is pushed out of the window of the rolling mill. The bending roll block to be replaced is supported on the hydraulic cylinder and then pushed into the rolling mill for reinstallation. When using this replacement device to replace the bending roll block, the support for the bending roll block is not stable enough, and the bending roll block is prone to tipping over. It is necessary to cooperate with a hoisting device to reposition the bending roll block, which will affect the disassembly, installation and replacement efficiency of the bending roll block. Moreover, this replacement method requires changing the position of the replacement device multiple times to replace multiple bending roll blocks, which also has a certain impact on the replacement efficiency of the bending roll block. There is a technical problem that the replacement efficiency of the bending roll block is not ideal enough. The embodiments of the present application provide a bending roll block replacement device, a rolling mill system and a bending roll block replacement method, which can at least solve the above technical problems to a certain extent.

[0047] The present application will be described below with reference to the accompanying drawings:

[0048] Figure 1 The use state diagram of a bending roll block replacement device in some embodiments or certain embodiments of the present application is shown. Refer to Figure 1 In this regard, the embodiments of the present application provide a bending roll block replacement device for replacing the bending roll block of a rolling mill. The rolling mill is provided with a roll changing track passing through its own window. The bending roll block replacement device includes:

[0049] A vehicle body 1 for moving along the roll changing track 1001;

[0050] At least two sliding members 2 are spaced apart and movably provided on the vehicle body 1, and an included angle is formed between the moving direction of the sliding member 2 and the extending direction of the roll changing track 1001;

[0051] At least two support members 3 are respectively and liftably provided on at least two sliding members 2, and the support members 3 are provided with support grooves 31 for placing the bending roll blocks 1003.

[0052] When replacing the bending roll block 1003 of the rolling mill 100 with the roll changing track 1001, the vehicle body 1 in the bending roll block replacing device can be moved along the roll changing track 1001. The roll changing track 1001 of the rolling mill 100 passes through the window 1002 of the rolling mill 100. The vehicle body 1 can be moved into the window 1002 of the rolling mill 100 where the bending roll block 1003 is installed. The sliding members 2 and the support members 3 on the vehicle body 1 will move into the window 1002 of the rolling mill 100 together with the vehicle body 1. At least two sliding members 2 are spaced apart and movably provided on the vehicle body 1, and an included angle is formed between the moving direction of the sliding member 2 and the extending direction of the roll changing track 1001. And at least two support members 3 are respectively and liftably provided on at least two sliding members 2. Then when the sliding member 2 is located in the window 1002, the support member 3 provided on the sliding member 2 can also be located in the window 1002. The sliding member 2 can move in a direction forming an included angle with the extending direction of the roll changing track 1001, so that the position of the sliding member 2 relative to the bending roll block 1003 on the side wall of the window 1002 can be changed. The support member 3 on the sliding member 2 moves with the sliding member 2, making the support groove 31 on the support member 3 more convenient for placing the bending roll block 1003. The support member 3 can be lifted relative to the sliding member 2 to support the bending roll block 1003, and then the bending roll block 1003 is disassembled from the frame of the rolling mill 100. The bending roll block 1003 can be stably supported in the support groove 31, reducing the possibility that the bending roll block 1003 topples over during disassembly, installation and movement and needs to be repositioned, improving the stability of the bending roll block 1003 during the movement after disassembly, so as to improve the replacement efficiency of the bending roll block 1003. And at least two support members 3 can also place at least two bending roll blocks 1003 to be replaced or disassembled, which is also beneficial to improving the replacement efficiency of multiple bending roll blocks 1003 on the rolling mill 100, and to a certain extent solving the technical problem that the replacement efficiency of the bending roll block 1003 is not ideal enough.

[0053] Moreover, the structure of this bending roll block replacing device is relatively simple and the manufacturing cost is relatively low.

[0054] It should be noted that after the bending roll block 1003 is disassembled from the rolling mill 100 and placed on the support member 3, the vehicle body 1 needs to be moved to move the bending roll block 1003 out of the rolling mill 100. The bending roll block 1003 to be replaced also needs to be placed on the support member 3 of the rolling mill 100 and moved into the window 1002 of the rolling mill 100 with the vehicle body 1 for replacement.

The bending roll block replacement device may further include bolts. The bolts (not shown in the figure) may be in threaded engagement with the threaded holes 331, and the nuts of the bolts and the vertical portion 33 may clamp the bending roll block 1003.

[0089] A rolling mill 100, the frame of the rolling mill 100 is provided with two windows 1002 and a roll-changing track 1001 connected to the frame and sequentially passing through the two windows 1002. Bending roll blocks 1003 are respectively installed on the two side walls of the window 1002, and a stop block 10031 is provided on each of the bending roll blocks 1003 installed in one of the windows 1002;

[0090] The bending roll block replacement device as described above, and the vehicle body 1 is used to move along the roll-changing track 1001 until it abuts against the stop block 10031.

[0091] The structure of the bending roll block replacement device and its corresponding technical effects can be referred to the above, and will not be elaborated here. The frame of the rolling mill 100 usually has windows 1002 on both the drive side and the operation side, and bending roll blocks 1003 are installed in both windows 1002. The bending roll blocks 1003 installed in one of the windows 1002 are all provided with stoppers 10031. The stopper 10031 can cooperate with the vehicle body 1. When the vehicle body 1 moves into the window 1002, the vehicle body 1 can abut against the stopper 10031 to achieve rapid positioning of the vehicle body 1, which is beneficial to improving the replacement efficiency of the bending roll block 1003.

[0092] In some or certain embodiments, one of the windows 1002 can be the window 1002 on the drive side of the rolling mill 100. In the window 1002 on the drive side, both of the two bending roll blocks 1003 can be provided with stoppers 10031, and the two stoppers 10031 are opposite to each other. The bending roll block 1003 on the drive side can play a positioning role. First, the bending roll block 1003 on the operation side of the rolling mill 100 is removed. After replacing the bending roll block 1003 on the operation side, the position of the replaced bending roll block 1003 on the operation side can be positioned by the positioning screw 8 and the two positioning members 9. The position of the vehicle body 1 can be kept stable. Finally, the bending roll block 1003 on the drive side is removed. The disassembly and assembly process of the bending roll block 1003 is relatively stable, and it is not necessary to adjust the position very much, which is also beneficial to improving the replacement efficiency of the bending roll block 1003.

[0093] It should be noted that Figure 5 Some structures of the rolling mill 100 are omitted.

[0094] Figure 6 The flow chart of a method for a bending roll block replacement device in some embodiments or certain embodiments of the present application is shown. Refer to Figure 6 , based on the same inventive concept, the present application also provides a method for replacing a bending roll block, which is implemented by using the bending roll block replacement device as described above, and the bending roll block on the rolling mill is an old bending roll block. The method for replacing a bending roll block includes:

[0095] S101: Place a bending roll block to be installed in the support groove of a support member.

[0096] S102: Move the vehicle body along the roll changing track until the support groove of another support member is opposite to the old bending roll block.

[0097] S103: Change the position of another support member until the old bending roll block is supported by another support member.

[0098] S104: Separate the old bending roll block from the rolling mill, and an installation position corresponding to the old bending roll block is formed on the rolling mill.

[0099] S105: Move the vehicle body along the roll changing track until the bending roll block to be installed is opposite to the installation position.

[0100] S106: Install the bending roll block to be installed at the installation position.

[0101] The structure of the bending roll block replacement device and its corresponding technical effects can be referred to the foregoing, and will not be elaborated here. During the process of replacing the bending roll block on the rolling mill, place the bending roll block to be installed in the support groove of a support member of the vehicle body. The support groove of the other support member moves with the vehicle body to be opposite to the old bending roll block, so that the old bending roll block can be separated from the rolling mill. The separated old bending roll block is supported in the support groove of the other support member. Then move the vehicle body to make the bending roll block to be installed move to the installation position left by disassembling the old bending roll block on the rolling mill, and install the bending roll block to be installed at the installation position. This way of replacing the bending roll block completes the disassembly of the old bending roll block and the reinstallation of the bending roll block to be installed during one stroke of the vehicle body along the roll changing track. It is not necessary to push the vehicle body out of the rolling mill after disassembling an old bending roll block and then place the bending roll block on the vehicle body again, realizing the rapid replacement of a bending roll block on the rolling mill, which is beneficial to improving the replacement efficiency of the bending roll block.

[0102] It should be noted that only for the convenience of understanding and for distinguishing from the bending roll block to be installed, the bending roll block originally installed on the rolling mill is named as the old bending roll block. The essence of the old bending roll block is the bending roll block installed on the rolling mill. The installation position formed after separating the old bending roll block on the rolling mill is essentially the position corresponding to the window of the rolling mill for installing the bending roll block.

[0103] In some embodiments, in step S103, change the position of the other support member until the old bending roll block is supported by the other support member. The sliding member can be moved relative to the vehicle body, and then the support member can be raised or lowered relative to the sliding member. The support groove of the support member can fit and support the old bending roll block. After the old bending roll block is supported, the old bending roll block can be directly disassembled, and then the vehicle body can be directly moved to push the old bending roll block out of the rolling mill, and then connect the bending roll block to be installed at the installation position.

[0104] In step S106 of some embodiments, to install the bending roll block to be installed at the installation position, the positions of the sliding member and the support member can also be adjusted so that the bending roll block to be installed can fit the installation position of the rolling mill better to complete the installation of the bending roll block.
