Description

Technical Field

[0001] This utility model relates to the field of casting and rolling equipment technology, and more specifically, to a universal joint bracket for an inclined casting and rolling mill. Background Technology

[0002] Casting and rolling is an important production technology in the field of metal sheet and strip production. It is widely used in the field of metal sheet and strip production because of its advantages such as low investment, quick results, high production efficiency, material consistency, low energy consumption, easy automation, and good metal structure.

[0003] Casting and rolling production is not only used in the ferrous metal production field, but also has a wide range of applications in the non-ferrous metal production field, such as aluminum and magnesium. Casting and rolling production is mainly divided into two categories: vertical and inclined. In vertical casting and rolling production, the casting and rolling mill and the transmission device are perpendicular to the ground. Therefore, when adjusting the roll gap and loading the rolls, the universal joint and the bracket only need to be adjusted vertically. However, in inclined casting and rolling production, because the casting and rolling mill body is tilted at a certain angle, when facing the processes of adjusting the roll gap, grinding, and loading the rolls, the universal joint and the bracket need to be adjusted horizontally in addition to vertically.

[0004] The traditional inclined universal joint brackets used in current casting and rolling mills are usually manually adjustable up and down and horizontally, and the contact surface is sliding friction. Therefore, they have problems such as low working efficiency, easy damage to the universal joint, poor support effect when the individual support position of each universal joint changes greatly, and short overall service life.

[0038] In all the accompanying drawings, the same reference numerals indicate similar or corresponding features or functions. Detailed Implementation

[0039] In response to the aforementioned problems, such as low working efficiency, easy damage to the universal joint shaft, poor support effect when the individual support position of each universal joint shaft changes greatly, and short overall service life of the traditional inclined casting and rolling mill universal joint bracket in the prior art, a universal joint bracket for inclined casting and rolling mill is proposed.

[0040] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0041] To illustrate the universal joint bracket for the inclined casting and rolling mill provided by this utility model Figure 1 The structure of the universal joint bracket of the inclined casting and rolling mill according to an embodiment of the present invention is shown; Figure 2 The structure of the upper bracket according to an embodiment of the present invention is shown; Figure 3 The structure of the lower bracket according to an embodiment of the present invention is shown; Figure 4 The mounting structure of the upper bracket bearing seat according to an embodiment of the present utility model is shown; Figure 5 The mounting structure of the lower bracket bearing seat according to an embodiment of the present invention is shown; Figure 6 The structure of the upper auxiliary support bracket according to an embodiment of the present invention is shown; Figure 7 A cross-sectional view of the upper bracket according to an embodiment of the present invention is shown.

[0042] like Figures 1 to 7As shown in the figure, the universal joint bracket for the inclined casting and rolling mill provided by this utility model mainly includes an upper bracket 1, a lower bracket 2, and a control mechanism (not shown in the figure); wherein,

[0043] The upper bracket 1 includes an upper bracket support leg 11, a slide seat 12 that is slidably disposed on the top of the upper bracket support leg 11 in the front-back direction, an upper support seat 13 disposed above the slide seat 12, an upper electrically controlled lifting mechanism disposed between the bottom of the upper support seat 13 and the top of the slide seat 12, and an electrically controlled horizontal adjustment mechanism disposed at the front of the slide seat 12.

[0044] The lower bracket 2 is located below the upper bracket 1 and includes a lower bracket support leg 21, a lower support seat 22 located above the lower bracket support leg 21, and a lower electrically controlled lifting mechanism located between the bottom of the lower support seat 22 and the top of the lower bracket support leg 21.

[0045] The upper support 13 and the lower support 22 have the same structure, both including a horizontal plate and a front inclined plate and a rear inclined plate respectively set at the front and rear ends of the top of the horizontal plate. The front inclined plate and the rear inclined plate are both inclined outward, and a rolling mechanism that contacts the universal joint shaft is provided on the inner side of the front inclined plate and the rear inclined plate.

[0046] The control mechanism is connected to the upper electrically controlled lifting mechanism, the electrically controlled horizontal adjustment mechanism, and the lower electrically controlled lifting mechanism, respectively.

[0047] It should be noted that the orientations "front" and "rear" in this utility model are set based on the continuous casting direction of the casting and rolling mill.

[0048] The upper universal joint of the casting and rolling mill is supported by the upper support seat 13, and the lower universal joint of the casting and rolling mill is supported by the lower support seat 22. Through the front and rear inclined plate structures of the upper support seat 13 and the lower support seat 22, as well as the rolling mechanism design on their inner surfaces, when the universal joint of the casting and rolling mill rests on the support seat, the inclined rolling mechanism contacts the universal joint, ensuring rolling friction between the universal joint and the support seat during bracket position adjustment. This avoids damage to the universal joint and extends its overall service life. The upper support seat 13 is adjusted via a control mechanism and a connecting device. The structural design of the upper electrically controlled lifting mechanism, the electrically controlled horizontal adjustment mechanism for adjusting the front and rear horizontal position of the upper support seat 13, and the lower electrically controlled lifting mechanism for adjusting the up and down position of the lower support seat 22 can automatically adjust the positions of the upper and lower support seats based on the digital values ​​of the casting and rolling mill tilt and verticality obtained by the control mechanism, the roll gap adjustment data during production, and the roll system size change data after grinding. This eliminates the need for manual adjustment, resulting in a high degree of automation, which improves work efficiency. Furthermore, the positioning of the upper and lower brackets is more accurate, thus providing better individual support for each universal joint shaft.

[0049] As a preferred embodiment of this utility model, a bracket base 4 is provided at the bottom end of the upper bracket leg 11; the bottom end of the lower bracket leg 21 is provided at the top end of the bracket base 4.

[0050] Specifically, the upper bracket support leg 11 and the lower bracket support leg 21 can be fixed to the bracket base 4 by bolts or welding. This utility model does not make any special limitations on this.

[0051] As a preferred embodiment of the present invention, the electrically controlled horizontal adjustment mechanism includes an upper bracket bearing seat 141 disposed at the front end of the slide 12, a first rolling bearing 142 disposed inside the upper bracket bearing seat 141, a horizontal moving rod 143 passing through the first rolling bearing 142, and an upper bracket horizontal motor 145 connected to the outer end of the horizontal moving rod 143 via a first coupling 144.

[0052] A nut 146 is fixed on the upper bracket support leg 11; the inner end of the horizontal moving rod 143 is a screw structure and passes through the nut 146. When the screw structure rotates, it cooperates with the nut 146 to perform a helical motion; an axial retaining ring 147 is provided at the end of the horizontal moving rod 143 with the screw structure where it passes through the upper bracket bearing seat 141.

[0053] Specifically, a slider can be provided at the top of the upper bracket leg 11 along the front-back direction, and a groove matching the slider can be provided at the bottom of the slide block 12. The slide block 12 is mounted on the slider through the groove, so that the slide block can slide horizontally back and forth at the top of the upper bracket leg 11. Of course, the slide block 12 can also be provided with a groove structure at the lower end, directly engaging with the top edge of the upper bracket leg 11, and a sliding copper plate can be provided in it, so that the slide block 12 can slide horizontally back and forth at the top of the upper bracket leg 11. This utility model does not make any special limitation on this.

[0054] The slide block 12 is provided with an upper bracket bearing seat 141, the aforementioned first rolling bearing 142, a horizontal moving rod 143, a first coupling 144, an upper bracket horizontal motor 145, a nut 146, and an axial retaining ring 147. The screw structure of the horizontal moving rod 143 can cooperate with the nut 146 fixed on the upper bracket support leg 11. The screw structure passes through the axial retaining ring 147 installed at the upper bracket bearing seat 141, so that when the upper bracket horizontal motor 145 drives the horizontal moving rod 143 to rotate, the screw structure and the helical motion of the nut 146 drive the upper bracket bearing seat 141 and the slide block 12 to move and adjust horizontally at the same time.

[0055] The aforementioned electronically controlled horizontal adjustment mechanism can also be replaced by a cylinder, hydraulic cylinder, etc.; the screw structure and nut structure of the horizontal moving rod can be replaced by a synchronous belt or chain drive structure, and this utility model does not impose any special limitations on this.

[0056] As a preferred embodiment of this utility model, the upper electrically controlled lifting mechanism includes a first spiral jack 151 disposed between the bottom of the upper support seat 13 and the top of the slide seat 12, an upper bracket lifting connecting rod 152 connected to the output rod of the first spiral jack 151, and an upper bracket lifting motor 154 connected to the end of the upper bracket lifting connecting rod 152 via a second coupling 153.

[0057] The upper bracket bearing seat 141 has an upper and lower stepped structure. The first rolling bearing 142 is located in the lower part of the upper bracket bearing seat 141, and the second rolling bearing 155 is located in the upper part of the upper bracket bearing seat 141.

[0058] The upper bracket lifting connecting rod 152 passes through the inside of the second rolling bearing 155.

[0059] Specifically, the upper bracket bearing housing 141 features a stepped shaft design for both the upper bracket lifting connecting rod 152 and the horizontal moving rod 143, and is equipped with rolling bearings at the installation positions to ensure transmission operation. The mounting plate of the upper bracket bearing housing 141 can be bolted to the front end of the slide block 12 via elongated holes, ensuring that even after long-term operation, the positioning position can still be adjusted to maintain alignment, thus extending its service life.

[0060] The upper electrically controlled lifting mechanism can be replaced by a hydraulic cylinder, a linear motor, or a gear and rack mechanism, etc., and this utility model does not impose any particular limitation on it. The output shaft of the first screw jack 151 can be connected to the upper support lifting connecting rod 152 via a pin.

[0061] As a preferred embodiment of the present invention, a first lifting guide column 16 is provided between the upper support 13 and the slide 12; the first lifting guide column 16 is provided on one side of the first screw jack 151.

[0062] Specifically, a first lifting guide column 16 is installed below the upper support base 13 to ensure the stability of the upper support base 13 during the lifting process. The first lifting guide column 16 can adopt a structure with an inner rod, an outer fixed base, and a copper sleeve in the middle to ensure vertical lifting guidance. Alternatively, the first lifting guide column 16 can adopt a hydraulic rod, a telescopic rod, or a structure with upper and lower sleeves (e.g., the top of the upper sleeve is fixed to the bottom of the upper support base 13, the lower sleeve is fixed to the top of the slide block 12, and the bottom of the upper sleeve is connected to the top of the lower sleeve). This invention does not impose any particular limitation on this. Both the upper and lower ends of the first lifting guide column 16 can be detachably connected to the bottom of the upper support base 13 and the top of the slide block 12 respectively using bolts. Other detachable connecting parts can also be used for fixation, facilitating assembly and disassembly.

[0063] As a preferred embodiment of this utility model, the lower electric lifting mechanism includes a second spiral lift 231 disposed between the bottom of the lower support seat 22 and the top of the lower bracket support leg 21, a lower bracket lifting connecting rod 232 connected to the output rod of the second spiral lift 231, and a lower bracket lifting motor 234 connected to the end of the lower bracket lifting connecting rod 232 via a third coupling 233.

[0064] A lower bracket bearing seat 235 is provided on one side of the lower bracket support leg 21, and a third rolling bearing is provided inside the lower bracket bearing seat 235; the lower bracket lifting connecting rod 232 passes through the inside of the third rolling bearing.

[0065] Specifically, the lower bracket is mainly used to support the lower universal joint shaft of the casting and rolling mill, and its strength is sufficient to bear the weight of a single joint shaft. Since the lower universal joint shaft is located at a low position, its horizontal position changes little due to changes in tilt angle and roll gap. Therefore, a lower support base with an inclined plate can meet the horizontal displacement of the lower universal joint shaft during operation, so the lower bracket does not need to be equipped with a horizontal adjustment device.

[0066] The mounting plate of the lower bracket bearing seat 235 can be fixed to the lower bracket support leg 21 by bolts through elongated holes, ensuring that the positioning position can still be adjusted to maintain alignment after long-term operation, thus extending its service life. The lower electrically controlled lifting mechanism can be replaced by a hydraulic cylinder, linear motor, or gear and rack mechanism, etc., and this utility model does not particularly limit it. The output shaft of the second screw jack 231 can be connected to the lower bracket lifting connecting rod 232 by a pin.

[0067] As a preferred embodiment of this utility model, a second lifting guide column 24 is provided between the lower support base 22 and the lower bracket leg 21; the second lifting guide column 24 is provided on one side of the second screw jack 231.

[0068] Specifically, a second lifting guide column 24 is installed below the lower support base 22 to ensure the stability of the lower support base 22 during lifting. The second lifting guide column 24 can adopt a structure with an inner rod, an outer fixed base, and a copper sleeve in the middle to ensure vertical lifting guidance. Alternatively, the second lifting guide column 24 can adopt a hydraulic rod, a telescopic rod, or a structure with upper and lower sleeves (e.g., the top of the upper sleeve is fixed to the bottom of the lower support base 22, the lower sleeve is fixed to the top of the lower bracket leg 21, and the bottom of the upper sleeve is connected to the top of the lower sleeve). This invention does not impose any particular limitation on this. The upper and lower ends of the second lifting guide column 24 can be detachably connected to the bottom of the lower support base 22 and the top of the lower bracket leg 21 respectively by bolts. Other detachable connectors can also be used for fixation, facilitating assembly and disassembly.

[0069] As a preferred embodiment of this utility model, an upper auxiliary support bracket is provided on the top of the upper bracket leg 11; the upper auxiliary support bracket is provided on the outside of the upper support seat 13;

[0070] The upper auxiliary support bracket includes an upper auxiliary support base 51 fixed to one side of the upper bracket support leg 11, an upper auxiliary support block 52 disposed above the upper auxiliary support base 51, and an upper auxiliary support lift 53 disposed between the top of the upper auxiliary support base 51 and the bottom of the upper auxiliary support block 52.

[0071] A first handwheel 54 is provided at the output shaft of the upper auxiliary support elevator 53.

[0072] As a preferred embodiment of this utility model, a lower auxiliary support bracket is provided on the top of the lower bracket leg 21; the lower auxiliary support bracket is located on the outside of the lower support base 22;

[0073] The lower auxiliary support bracket includes a lower auxiliary support base 61 fixed on one side of the lower bracket support leg 21, a lower auxiliary support block 62 disposed above the lower auxiliary support base 61, and a lower auxiliary support lift 63 disposed between the top of the lower auxiliary support base 61 and the bottom of the lower auxiliary support block 62.

[0074] A second handwheel 64 is provided at the output shaft of the lower auxiliary support elevator 63.

[0075] Specifically, upper and lower auxiliary support brackets are respectively located in the upper bracket 1 and lower bracket 2 areas to support the portion of the universal joint shaft that is longer than the bracket, thus providing auxiliary support. The auxiliary support base is preferably welded and fixed to the bracket legs. An auxiliary support lift is installed on the auxiliary support base, with a handwheel installed on the output shaft of the auxiliary support lift. An auxiliary support block is installed above it. The auxiliary support bracket initially assists in supporting the universal joint shaft through manual adjustment; subsequent automatic adjustments do not require manual intervention from the auxiliary support bracket. The auxiliary support block is preferably, but not limited to, made of square steel, which possesses good strength and internal space for deformation under heavy pressure, thereby protecting the universal joint shaft.

[0076] As a preferred embodiment of this utility model, the rolling mechanism is a heavy-duty ball 3.

[0077] It should be noted that the rolling mechanism is preferably, but not limited to, heavy-duty ball 3, but can also be replaced by non-heavy-duty ball. The contact surface can be replaced by a low-friction coefficient composite material liner or roller array, as long as the rolling friction function can be met. This utility model does not make any special limitations in this regard.

[0078] As a preferred embodiment of this utility model, the tilt angles of both the front tilt plate and the rear tilt plate are 23°.

[0079] It should be noted that the tilt angle of both the front and rear tilt plates is preferably, but not limited to, 23°; the tilt angle can be determined according to the size of the universal joint.

[0080] Specifically, the control mechanism in this utility model is preferably, but not limited to, a PLC control system. It stores instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog input / output. In this utility model's technical solution, taking the PLC control system as an example, it is equipped with a touchscreen. Digital values ​​of the casting and rolling mill's tilt and verticality, roll gap adjustment data during production, and roll system dimensional changes after grinding are input into the PLC control system via the touchscreen. Using a preset logic program within the PLC control system, the received data is processed (e.g., the horizontal and vertical movement of the universal joint shaft is calculated based on the casting and rolling mill's tilt or verticality, which is the horizontal and vertical movement of the bracket; the horizontal and vertical movement of the universal joint shaft is calculated based on the roll gap adjustment). This generates different instructions for the lifting motor used to drive the upper and lower brackets' lifting and lowering adjustment and for the horizontal motor used to drive the upper bracket's horizontal forward and backward adjustment, causing the motors to perform corresponding movements, thereby achieving automated bracket adjustment.

[0081] After the universal joint of the inclined casting and rolling mill is disengaged from the rollers of the casting and rolling mill, the universal joint bracket of the inclined casting and rolling mill described above is used to support the universal joint of the inclined casting and rolling mill.

[0082] As can be seen from the above specific embodiments, the universal joint bracket for the inclined casting and rolling mill provided by this utility model has an upper support seat supporting the upper universal joint of the casting and rolling mill, and a lower support seat supporting the lower universal joint of the casting and rolling mill. Through the front and rear inclined plate structures of the upper and lower support seats, and the rolling mechanism design on their inner surfaces, when the universal joint of the casting and rolling mill rests on the support seat, the inclined rolling mechanism contacts the universal joint, ensuring rolling friction between the universal joint and the support seat during bracket position adjustment, thus avoiding damage to the universal joint and extending its overall service life. Through the control mechanism... The structural design of the upper electrically controlled lifting mechanism for adjusting the vertical position of the upper support seat, the electrically controlled horizontal adjustment mechanism for adjusting the front-to-back horizontal position of the upper support seat, and the lower electrically controlled lifting mechanism for adjusting the vertical position of the lower support seat, connected to the upper electrically controlled lifting mechanism, allows for automatic adjustment of the positions of the upper and lower support seats based on the digital values ​​of the casting and rolling mill tilt and verticality obtained by the control mechanism, the roll gap adjustment data during production, and the dimensional change data of the roll system after grinding. This eliminates the need for manual adjustment, resulting in a high degree of automation, which improves work efficiency. Furthermore, the positioning of the upper and lower brackets is more accurate, thus providing better individual support for each universal joint shaft.

[0083] The universal joint bracket for an inclined casting and rolling mill according to the present invention has been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the universal joint bracket for an inclined casting and rolling mill according to the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
