[0025] Combination Figure 1 The crystallizer is installed on the vibrating movable water tank, fixed by bolts, and vibrates up and down with the vibrating hydraulic cylinder in the vertical direction with an amplitude of ±3mm. Different from the traditional four-bar linkage, the up and down vibration of the vibrating water tank is guided by the roller unit in the longitudinal direction and by the positioning block in the transverse direction. For the entire casting machine, the longitudinal direction generally refers to the direction of motion of the billet, that is, the billet drawing direction, while the transverse direction refers to the length direction along the cross-section of the large slab billet. There is an SKF locating bearing on each side of the transverse guide positioning block, which is not prone to failure. The longitudinal guidance relies on the roller unit for guidance. The roller unit includes a fixed plate 2, a movable plate 3 and a roller body 1. The roller body 1 is connected between the fixed plate 2 and the movable plate 3. The working principle diagram of the roller unit is as shown in the figure. Figure 1 shown.
[0026] (1) The movable plate 3 of the roller unit is fixed to the movable water tank of the crystallizer vibration table by bolts, and is in an up and down vibration state during operation. The side of the movable plate 3 and the fixed plate 2 relative to the roller body 1 is a guide surface;
[0027] (2) The roller unit body has arc-shaped outer edges on both sides and can roll between the movable plate 3 and the fixed plate 2 during operation;
[0028] (3) The fixed plate 2 of the roller unit is fixed to the vibration fixed side frame of the crystallizer by bolts and is in a fixed state during operation.
[0029] from Figure 1 It can be seen that during the up and down vibration of the movable water tank of the crystallizer vibration device, the roller unit plays a longitudinal guiding role, that is, the roller body 1 with an arc-shaped outer edge rolls between the two guide surfaces, and the roller body 1 forms a rolling friction pair with the two guide surfaces. As long as the outer edge of the roller body 1 is not worn and the guide surfaces of the movable plate 3 and the fixed plate 2 are not worn, the roller unit can play a precise guiding role to ensure that the vertical deflection of the crystallizer vibration vibrates up and down with an accuracy of ≤±0.05mm. Excessive crystallizer vibration deflection will affect the quality of the ingot, and in severe cases will cause serious accidents such as steel leakage in the casting machine. Therefore, in order to ensure the quality of the ingot, it is necessary to detect the assembly accuracy of the roller unit to ensure that the vertical deflection of the crystallizer vibration vibrates up and down with an accuracy of ≤±0.05mm. However, in the related technology, there is a lack of a device that can perform precision detection on the roller unit.
[0030] Based on this, an embodiment of the present application provides a crystallizer vibration roller unit detection device, which can detect the assembly accuracy of the roller unit to ensure the quality of the casting.
[0031] The following is a description of the embodiments of the present application in conjunction with the accompanying drawings:
[0032] Combination Figure 2 The embodiment of the present application provides a crystallizer vibration roller unit detection device 100, including: a detection bracket 110, a driving mechanism 120 and a detection member. The detection bracket 110 is a basic component of the detection device 100, and is used to provide installation and protection for at least other components of the detection device 100 and the roller unit. The roller unit and the driving mechanism 120 are both arranged in the detection bracket 110, the fixed plate 2 is fixedly connected to the detection bracket 110, the driving mechanism 120 is used to drive the movable plate 3 to move up and down, and the detection member is used to detect the deflection amount of the movable plate 3 during the movement.
[0033] Since the fixed plate 2 is in a fixed state during operation, the fixed plate 2 is fixedly connected to the detection bracket 110, which can simulate the state of the fixed plate 2 being fixed to the crystallizer vibration fixed side frame during operation. Since the movable plate 3 is fixed to the movable water tank of the crystallizer vibration table by bolts during operation and is in an up and down vibration state, the driving mechanism 120 is used to drive the movable plate 3 to move up and down, which can simulate the up and down vibration state of the movable plate 3 during operation. At this time, the deflection amount of the movable plate 3 during the movement process is detected by the detection part, and the deflection amount of the roller unit in the actual working state can be obtained. Specifically, the detection part can be a dial indicator.
[0034] The present application provides a crystallizer vibration roller unit detection device 100. Since the roller unit and the driving mechanism 120 are both arranged in the detection bracket 110, the fixed plate 2 is fixedly connected to the detection bracket 110, and the driving mechanism 120 is used to drive the movable plate 3 to move up and down, it can simulate the movement of the movable plate 3 during the crystallizer vibration process. In this process, the deflection amount of the movable plate 3 is detected by the detection part, so as to detect the assembly accuracy of the roller unit, thereby ensuring the quality of the casting.
[0035] In some embodiments, the detection bracket 110 includes a base 111, a first mounting plate 112 and a second mounting plate 113, the first mounting plate 112 and the second mounting plate 113 are arranged opposite to each other, the first mounting plate 112 is installed on the base 111, the second mounting plate 113 is connected to the driving mechanism 120, the fixed plate 2 is connected to the first mounting plate 112, and the movable plate 3 is connected to the second mounting plate 113.
[0036] Since the movable plate 3 and the fixed plate 2 are arranged opposite to each other in the roller unit, the first mounting plate 112 and the second mounting plate 113 are also arranged opposite to each other to facilitate the connection between the movable plate 3 and the fixed plate 2. The first mounting plate 112 is mounted on the base 111, and the fixed plate 2 is connected to the first mounting plate 112, that is, the fixed plate 2 is fixed in the detection bracket 110, and the second mounting plate 113 is connected to the driving mechanism 120, and the movable plate 3 is connected to the second mounting plate 113, that is, the driving mechanism 120 drives the second mounting plate 113 to move up and down, thereby driving the movable plate 3 to move up and down.
[0037] In some embodiments, the driving mechanism 120 includes a driving member 121 and a transmission member 122. The driving member 121 is installed on the base 111. The second mounting plate 113 is connected to the transmission member 122. The driving member 121 and the transmission member 122 transmit each other to drive the movable plate 3 to move up and down.
[0038] The driving member 121 and the transmission member 122 transmit each other, so that the transmission member 122 can move up and down. Since the movable plate 3 is connected to the transmission member 122, the transmission member 122 can drive the movable plate 3 to move up and down. The transmission member 122 can be supported on the second mounting plate 113, that is, the transmission member 122 and the second mounting plate 113 can only be in contact with each other. During the movement, the transmission member 122 drives the second mounting plate 113 to move through the supporting force. The transmission member 122 and the second mounting plate 113 can also be connected to form a whole, and there is no limitation on this.
[0039] In some embodiments, the driving member 121 and the transmission member 122 are threadedly connected.
[0040] The driving member 121 may be a nut, and the transmission member 122 may be a screw rod. The screw rod may be rotated to make the screw rod and the nut thread transmission, and the movable plate 3 may be driven to move up and down. Of course, the driving member 121 may be a screw rod, and the transmission member 122 may be a nut. The driving member 121 and the transmission member 122 may form a ball screw, so that the screw rod is rotated, and the nut may drive the movable plate 3 to move up and down, and the transmission member 122 may be rotated by manual or electric drive, and there is no limitation to this.
[0041] In some embodiments, the driving mechanism 120 further includes a handwheel 123 , and the handwheel 123 is disposed on the transmission member 122 .
[0042] The transmission member 122 can be rotated by manual drive, so a hand wheel 123 is provided on the transmission member 122, and the operator can rotate the hand wheel 123 to rotate the transmission member 122 to realize the up and down movement of the movable plate 3, thereby improving the operating convenience of the operator.
[0043] In some embodiments, in actual applications, the movable plate 3 of the roller unit is fixed on the movable water tank of the crystallizer vibration table, and its vibration is relatively stable. Therefore, in order to make the vibration simulation of the movable plate 3 in the detection device 100 more accurate, thereby making the movement of the movable plate 3 more stable and the measured deflection more accurate, the detection device 100 also includes a guide mechanism 130, and the guide mechanism 130 is connected to the second mounting plate 113 to guide the movement of the movable plate 3.
[0044] In some embodiments, the guide mechanism 130 includes a guide wheel 131 and a guide rail 132 . The guide rail 132 is installed on the base 111 . The guide wheel 131 is slidably disposed in the guide rail 132 and is connected to the second mounting plate 113 .
[0045] The guide rail 132 is arranged along the moving direction of the movable plate 3. When the driving mechanism 120 drives the second mounting plate 113 to drive the movable plate 3 to move up and down, since the guide wheel 131 is connected to the second mounting plate 113, the second mounting plate 113 simultaneously drives the guide wheel 131 to move in the guide rail 132, thereby providing guidance for the movement of the movable plate 3, making the movement of the movable plate 3 more stable.
[0046] The guide wheel 131 is rotatably arranged in the mounting seat 133, and the mounting seat 133 is connected to the second mounting plate 113. Since there may be a gap in the roller unit, which may cause detection errors, the roller unit needs to be clamped before detection to eliminate the gap. In some embodiments, the mounting seat 133 is provided with a threaded hole, and a top screw is installed in the threaded hole, which can play the function of clamping the roller unit.
[0047] In some embodiments, since the roller unit has a certain weight, in order to strengthen the structural strength of the detection bracket 110, the detection bracket 110 includes a first reinforcing rod 114, one end of the first reinforcing rod 114 is connected to the first mounting plate 112, and the other end is connected to the base 111. Similarly, in order to strengthen the structural strength of the guide mechanism 130, the guide mechanism 130 includes a second reinforcing rod 134, one end of the second reinforcing rod 134 is connected to the guide rail 132, and the other end is connected to the base 111.
[0048] Next, the method for using the crystallizer vibration roller unit detection device 100 provided in the embodiment of the present application is described;
[0049] 1) Connect the fixed plate 2 to the first mounting plate 112 and the movable plate 3 to the second mounting plate 113 to install the roller unit in the detection bracket 110;
[0050] 2) Pre-tighten the top screw on the mounting seat 133 to achieve the clamping function of the roller unit and eliminate the gap of the roller unit;
[0051] 3) Use a level to test the installation of the roller unit to ensure that there is no deviation up, down, left, or right after the roller unit is installed;
[0052] 4) The transmission member 122 is rotated by the hand wheel 123 to move the movable plate 3 up and down, and the up and down movement amount is ±20 mm;
[0053] 5) Use a dial indicator to detect the left and right deflection of the movable plate 3, and the deflection amount is set according to the vibration accuracy.
[0054] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
[0055] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
