Description

Technical Field

[0001] This utility model relates to the field of handling device technology, specifically to a stable bidirectional steel coil turning machine. Background Technology

[0002] With the rapid development of my country's economy, steel rolling enterprises are becoming increasingly widespread. Industrial processes require cold rolling, annealing, and finishing of steel strips. These steps necessitate changing the coils from horizontal to vertical placement. Therefore, coil turning devices are crucial equipment in steel production and processing. Traditional manual turning methods are inefficient, pose significant safety hazards, and cannot meet the demands of modern production. With the development of automation technology, hydraulic and electric turning machines are becoming more common. However, existing unidirectional and bidirectional hydraulic turning machines suffer from low flexibility and poor reliability in overcoming critical turning points. Electric turning machines, even with added safety stabilizers, operate in a unidirectional manner and cannot continuously turn the coils. This means that after the coils are turned vertically, they must be run back to their original position under no-load conditions, resulting in energy loss and a reduced overall fatigue life of the device.

[0003] To overcome the above problems, a gear-driven, electric, stable, bidirectional steel coil turning machine was invented, which improves work efficiency, has good stability, and increases the fatigue life of the device. Summary of the Invention

[0004] The purpose of this invention is to overcome the limitations of existing gear-driven steel coil turning machines that require the addition of a stabilizing seat to achieve bidirectional turning operations, and to provide a safe and reliable dual-operation steel coil turning machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A stable bidirectional steel coil turning machine includes a base, a turning table is provided above the base, and the inner side of the lower surface of the turning table is a symmetrical arc support track, which cooperates with the support rollers provided on the upper surface of the base. The four support rollers support the turning table, and in this state, the gear transmission is not affected by the gravity of the turning table and the steel coil. A reducer is located below the base. The reducer's output shaft consists of three rows of sprockets, which transmit power to a rotating shaft via chain drive. The rotating shaft is supported by bearing seats spanning both sides. Gears nested on both sides of the rotating shaft mesh with circular racks on both sides of the tilting platform, causing the entire tilting platform to rotate 90° back and forth along an arc on four support rollers. A telescopic stabilizing seat is located above the tilting platform. This telescopic stabilizing seat comprises a steel plate support, linear guide rails, a V-shaped support seat, and a slider hinge seat. The two ends of the steel plate support, the V-shaped support seat, and the slider hinge seat form two pairs of rotating joints. These joints are connected by hinges, forming three pairs of crank-slider mechanisms. The steel plates are welded to six steel plate supports. A hydraulic cylinder located below the tilting platform provides power to the telescopic stabilizing seat. When the hydraulic cylinder is in its initial position, the telescopic stabilizing seat forms a concave surface with the V-shaped concave platform, forming a V-shaped stabilizing seat. The steel coil is placed horizontally on the stabilizing seat. When the hydraulic cylinder is in its extreme position, the telescopic stabilizing seat forms a support surface. The first and second platform surfaces have the same structure.

[0006] The following technical solution involves a first platform placed horizontally and a second platform placed vertically in the initial state. The hydraulic cylinder of the first platform is controlled by the operator to the initial position, while the second platform is controlled to the limit position. During operation, the operator first uses a gantry crane or forklift to place the steel coil horizontally on the first platform, ensuring that the circular bottom surface of the steel coil contacts the support surface. The reducer is then started, and the gear and rack meshing drives the tilting platform to rotate 90 degrees. At this point, the reducer is stopped, and the operator transports the steel coil to the designated position. Subsequently, the operator controls the hydraulic cylinder of the first platform to the limit position, while the second platform is in the initial position. This process is repeated to complete continuous work. The tilting machine achieves bidirectional operation, improving work efficiency. At the same time, the stabilizing seat reduces the possibility of the steel coil slipping from both sides, ensuring the safety of the operator.

[0007] This utility model is further optimized so that the height of the support column is exactly the same as the horizontal height of the flipping table and the base, which offsets part of the rotational torque generated when the flipping table is stationary, and at the same time prevents the flipping table from running out of the limit and causing an accident.

[0008] This invention is further optimized by using a three-row sprocket for the speed reducer drive assembly to increase torque and load-bearing capacity.

[0009] This invention is further optimized by designing the arc of the tilting table as a track surface, which cooperates with the track groove of the supporting rollers to limit the tilting table from shifting and increase stability. At the same time, the gear transmission is not affected by the gravity of the tilting table and the steel coil, improving transmission efficiency and reliability.

[0010] This utility model is further optimized, wherein the hydraulic cylinder is set at a reasonable position on the tilting table, forming a V-shaped stabilizing seat at the lower limit position and a supporting plane at the upper limit position, and the telescopic stabilizing seat is aligned with the steel plate bracket and the linear guide rail when in the supporting surface state.

[0011] Compared with the prior art, the present invention has the following technical effects:

[0012] 1. Add a support column above the base to offset part of the rotational torque generated when the tilting table is stationary, and at the same time prevent the tilting table from running out of the limit and causing an accident.

[0013] 2. The arc track on the lower surface of the tilting table matches the track groove of the supporting rollers to prevent the tilting table from shifting to either side and to increase the stability of operation.

[0014] 3. Add a telescopic stabilizing seat to ensure the stability of horizontally placed steel coils. The telescopic stabilizing seat allows for the placement of horizontal or vertical steel coils, enabling bidirectional operation of the steel coil turning machine and improving work efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: A stable bidirectional steel coil turning device, such as Figure 1 As shown, the steel coil turning device includes a base 1, a turning table 2, and a telescopic stabilizing seat 3, as follows: Figure 2 The upper surface of the base 1 shown includes four symmetrically arranged bearing seats 109, which are fixed to the upper surface of the base 1 by bolts. Rolling bearings are installed on both sides of the rotating shaft 104, and the installation is achieved through an interference fit between the rolling bearings and the bearing seats 109. Symmetrical gears 107 and support rollers 106 are installed on the rotating shaft 104. The gears 107 and support rollers 106 are axially positioned by sleeves. The driven sprocket 103 and gears 107 are both circumferentially positioned by key connections, thus restricting their circumferential movement. Three rows of chains 102 are respectively connected to… The driving sprocket 108 meshes with the driven sprocket 103, driving the rotating shaft 104 to rotate. The gears 107 on both sides mesh with the circular racks 201 on both sides, thereby driving the tilting table 2 to rotate. The symmetrical support rollers 106 on the other side are respectively sleeved on the support roller shaft 110. The support roller shaft 110 is installed by an interference fit between the rolling bearing and the bearing seat 109. The support rollers 106 are axially positioned on both sides by sleeves. The entire tilting table 2 is placed on the four support rollers 106. This drive increases the starting torque to a certain extent and meets the heavy load conditions of the steel coil device.

[0026] like Figure 2The base 1 shown also includes four symmetrical support columns 101. The support columns 101 are fixed to the upper surface of the base 1 by bolts. The height of the support columns 101 is equal to the initial position height of the tilting table 2. This can offset part of the torque generated by the steel coil when the tilting table 2 is stationary, and at the same time prevent the tilting table 2 from turning out of the limit and causing the steel coil 4 to roll off the worktable, thus creating a safety hazard.

[0027] like Figure 2 and Figure 3 The tilting table 2 shown includes a circular rack 201, an arc-shaped support rail 202, a linear guide rail 203, a V-shaped recess 204, and a hydraulic cylinder 205. The lower surface of the tilting table 2 is a symmetrical arc surface, on which the circular rack 201 is welded, concentric with the arc surface. The entire tilting table 2 can be regarded as a large driven gear, as shown in the figure. Figure 1 and Figure 4 The circular arc support track 202 shown is designed to mesh with the track groove of the support roller 106. The diameter of the support arc surface of the support roller 106 is larger than the tip circle diameter of the gear 107. The entire tilting table 2 is placed on the four support rollers. In this state, the root and tip of the gear 107 and the circular rack 201 are not affected by the gravity of the tilting table 2 and the steel coil 4, so that the rotation of the gear 107 makes the entire tilting table 2 rotate back and forth 90° along the arc surface on the base 1.

[0028] like Figure 3 The upper surface of the tilting table 2 includes two mutually perpendicular first table surfaces 206 and second table surfaces 207. It is noted that the mounting parts and their own structures on the two table surfaces are equal. The focus is on the feature of one table surface: a V-shaped recess 204 is provided at the end of the table surface, which is consistent with the conversion groove structure of the telescopic stabilizer 3, forming a large V-shaped stabilizer. This allows the horizontal steel coil 4 to be stably placed on the V-shaped stabilizer, reducing the possibility of the steel coil 4 rolling off the V-shaped stabilizer and improving the safety of the equipment operation.

[0029] like Figure 4 The telescopic stabilizer 3 includes a linear guide rail 203 bolted to the tilting table 2, and a slider hinge seat 303 bolted above the linear guide rail slider 304. Figure 5 A sliding hinge seat 303 forms a revolute joint with one end of the steel plate bracket 301, and the other end of the steel plate bracket 301 forms a revolute joint with the V-shaped support seat 302. The two revolute joints are connected by a hinge. Finally, two steel plates 305 are each welded to three pairs of steel plate brackets 301, forming a telescopic stabilizing seat 3. The power source for the telescopic stabilizing seat 3 is a hydraulic cylinder 205. The hydraulic cylinder 205 is bolted to a suitable position on the tilting table 2. The inherent threaded rod above the hydraulic cylinder 205 mates with the threaded hole of the V-shaped support seat. Figure 4When the hydraulic cylinder 205 is in its initial position, the telescopic stabilizing seat 3 and the V-shaped recess 204 have the same shape, forming a large V-shaped stabilizing seat for horizontal placement of the steel coil 4. When the hydraulic cylinder 205 is in its extreme position, the steel plate support 301, the linear guide rail 203, and the linear guide rail slider 304 are on the same horizontal line, and the telescopic stabilizing seat 3 forms an effective support plane for vertical placement of the steel coil 4. Therefore, the telescopic stabilizing seat 3 allows the first table 206 or the second table 207 to be either a horizontal or vertical table, enabling the steel coil turning device to achieve bidirectional turning and continuous operation, thus improving overall production efficiency and reducing the energy loss of existing circular steel coil turning machines during no-load return.

[0030] Operating procedure: First, the operator lowers the telescopic stabilizing seat 3 of the first platform 206 to its limit position using hydraulic cylinder 205, transforming it into a stabilizing seat. Simultaneously, the telescopic stabilizing seat 3 of the second platform 207 rises to its limit position using hydraulic cylinder 205, transforming it into a supporting seat. The first platform 206 then rotates to... Figure 6 In the initial state, the workers first use a forklift or overhead crane to place the horizontal steel coil 4 on the stable seat of the first platform, ensuring that the bottom of the steel coil contacts the support surface of the second platform 207. Then, the reduction motor 105 is started, and through the meshing of the gear 107 and the circular rack 201, the tilting table 2 is driven to rotate to the desired position. Figure 7 After positioning, the reducer 105 is stopped, and then the workers transport the steel coil 4 to the designated location. At this time, the second platform 207 is horizontal and the first platform 206 is vertical. The workers only need to control the hydraulic cylinder 205 to turn the telescopic stabilizing seat 3 of the first platform 206 into a support seat and the telescopic stabilizing seat 3 of the second platform into a stabilizing seat. The steel coil 4 is then placed horizontally on the second platform 207, enabling continuous operation without the need to return to the original state under no-load conditions.
