Description

Technical Field

[0001] This utility model relates to the field of hot-rolled steel plate processing technology, and in particular to a quick-change mechanism for the roller system of a hot-rolled steel plate leveling machine. Background Technology

[0002] In the industrial production process of sheet metal, from rolling, cutting, heat treatment, cooling to subsequent transportation, the sheet metal is easily affected by multiple factors such as fluctuations in process parameters, external forces, and environmental factors. Various morphological defects are easily generated in the sheet metal. Typical defects include wavy deformation, overall twisting, sickle-shaped bending, and local bulging. These defects not only seriously damage the appearance flatness of the sheet metal, but also have a fatal impact on the subsequent processing accuracy, assembly quality, and final product performance. They have become the core bottleneck restricting the improvement of sheet metal production quality. In order to solve the above problems and meet the demand for efficient leveling of large-area and multi-specification sheet metal, the industry has gradually developed and promoted mechanical multi-roller leveling machines. Compared with the traditional manual hammering leveling method, this type of equipment effectively overcomes the limitations of poor leveling effect, unstable accuracy, and low production efficiency in the leveling of large-area and thick sheet metal by manual operation. It significantly improves the automation level and production efficiency of the sheet metal leveling process and has become one of the key equipment in modern sheet metal processing production lines.

[0003] However, existing multi-roller steel plate leveling machines still have shortcomings in practical applications. During long-term operation, the pressure rollers, as the core working components, inevitably experience wear, deformation, or even damage due to continuous contact and friction with the metal plate and the application of significant pressure. This affects the leveling accuracy and quality of the plate. Current repair methods for damaged pressure rollers have significant flaws: when a pressure roller needs repair or replacement, the operator must disassemble the entire leveling machine to remove the damaged roller. After the roller is repaired or replaced, the leveling machine must be reassembled. The traditional repair method of installation and debugging is not only complex and time-consuming, but also leads to prolonged downtime of the leveling machine, seriously affecting the normal production progress of enterprises, significantly reducing production efficiency, and causing significant economic losses. It is evident that existing metal sheet leveling machines still have obvious shortcomings in terms of structural design rationality, maintenance and repair convenience, and core component repair efficiency, making it difficult to fully meet the needs of the modern metal sheet processing industry for efficient, low-cost, and high-precision leveling operations. Therefore, developing a metal sheet leveling machine with simplified structure, convenient maintenance, and high core component repair efficiency has important practical significance and market value. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a quick-change mechanism for the roller system of a hot-rolled steel plate leveling machine, which can more accurately solve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a quick-change mechanism for the roller system of a hot-rolled steel plate leveling machine, including a base plate, a fixed seat fixedly installed at the top center of the base plate, an electric push rod fixedly installed on the inner side of the fixed seat, a frame fixedly installed through the output end of the electric push rod through the fixed seat, a drive mechanism fixedly installed on one side of the frame, and mounting mechanisms rotatably connected to both sides of the frame. The outer side of the mounting mechanism is connected to the inner output end of the drive mechanism, and a pressure roller is installed inside the frame through the mounting mechanism.

[0007] The installation mechanism includes a turntable, which is linearly arranged at equal intervals and rotatably connected to both sides of the frame. The outer side of the turntable is connected to the inner output end of the drive mechanism. An installation rail is fixedly installed on the inner side of the turntable. An installation block is slidably connected inside the installation rail. A fixing arm is fixedly installed on the inner side of the installation block. The pressure roller is fixedly installed on the inner side of the installation block. A limit module is fixedly installed at the bottom of the installation rail. The limit module and the installation block are engaged.

[0008] Furthermore, mounting brackets are fixedly installed on both sides of the substrate, and mounting holes are provided at both ends of the outer side of the mounting brackets. The mounting holes are countersunk holes.

[0009] Furthermore, the limiting module includes a circular groove and a locking hole. The circular groove is located at the lower end of the mounting rail. A torsion spring is fixedly connected inside the circular groove. A connecting plate is fixedly installed on the outside of the torsion spring. The connecting plate is movably connected to the inside of the circular groove. A circular block is fixedly installed on the outside of the turntable. The circular block is rotatably connected to the inner and outer ends of the circular groove. A limiting arm is fixedly installed on one side of the circular block. The locking hole is located in the middle of the mounting block and on the upper end of the mounting rail near the limiting arm. The locking hole is arc-shaped. An arc-shaped locking pin is fixedly connected to the outer end of the limiting arm. The end of the arc-shaped locking pin penetrates the mounting rail and is inserted into the locking hole of the mounting block.

[0010] Furthermore, an adjustable handrail is fixedly connected to the side of the circular block away from the limiting arm, and a handrail ball is fixedly connected to the outer end of the adjustable handrail.

[0011] Furthermore, the mounting rail and mounting block are both convex in shape when viewed from above, and the locking holes and arc-shaped locking pins are arranged concentrically with the torsion spring.

[0012] Furthermore, the drive mechanism includes a side plate and a worm gear. The side plate is fixedly installed at both ends of one side of the frame. A drive assembly is fixedly connected to the outer side of the side plate. A worm is rotatably connected between the inner sides of the side plate. The worm gears are rotatably connected to the side of the frame near the side plate with equal spacing and arranged linearly. The worm gears and worm are connected by a drive. The inner sides of the worm gears and worm are fixedly connected to the outer side of the turntable.

[0013] Furthermore, the drive assembly includes a fixed plate and a driven gear. The fixed plate is fixedly installed on the outside of the side plate. A drive motor is fixedly installed on one side of the fixed plate. The output end of the drive motor passes through the fixed plate and is fixedly connected to a drive gear. The driven gear is rotatably connected to the side of the side plate near the driven gear. The drive gear and the driven gear are meshed together.

[0014] The beneficial effects of this utility model are:

[0015] 1. During the application of this technical solution, by setting up a mounting rail and mounting block with a convex structure, a limiting module with a torsion spring and an arc-shaped locking pin, and an easy-to-operate adjusting handle and handle ball, when the pressure roller is worn, deformed or damaged, the operator does not need to disassemble the entire leveling machine. They only need to pull the adjusting handle to rotate the round block, allowing the arc-shaped locking pin to disengage from the locking hole of the mounting block, and then slide the old pressure roller mounting block out along the mounting rail. After replacing the new pressure roller, the locking steps can be repeated. This achieves the effect of quick disassembly and assembly of the pressure roller, greatly shortens the replacement time, and reduces the downtime of the leveling machine. It solves the problem that the existing technology requires disassembling the entire machine for pressure roller replacement, which is cumbersome, time-consuming and leads to low production efficiency. It fully demonstrates the convenience of this technical solution in disassembly, assembly and maintenance.

[0016] 2. During the application of this technical solution, the drive mechanism, with its clear transmission path, well-defined division of labor, and no redundancy, coupled with an electric push rod that can adjust the position of the pressure roller, and mounting brackets and countersunk holes adapted to different work positions, makes the power transmission of the drive mechanism efficient and stable. During the leveling operation, the pressure of the pressure roller can be flexibly adjusted according to the specifications of the steel plate. During the equipment installation phase, it can be adapted to different models of leveling machines. During routine maintenance, faulty parts can be quickly located and handled individually. This achieves the effects of simplifying the equipment structure, reducing manufacturing and training costs, shortening the maintenance cycle, reducing maintenance costs, and ensuring leveling accuracy and effect. It solves the problems of complex structure, difficult maintenance and repair, high operating costs, and limited leveling accuracy of existing leveling machines, highlighting the significant advantages of the drive mechanism of this technical solution.

[0022] 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.

[0023] Example 1

[0024] A quick-change mechanism for the roller system of a hot-rolled steel plate leveling machine includes a base plate 1. A fixed seat 2 is fixedly installed at the top center of the base plate 1. An electric push rod 3 is fixedly installed on the inner side of the fixed seat 2. A frame 4 is fixedly installed through the fixed seat 2 at the output end of the electric push rod 3. A drive mechanism 6 is fixedly installed on one side of the frame 4. Mounting mechanisms 7 are rotatably connected to both sides inside the frame 4. The outer side of the mounting mechanism 7 is connected to the inner output end of the drive mechanism 6. A pressure roller 5 is installed inside the frame 4 through the mounting mechanism 7.

[0025] The mounting mechanism 7 includes a turntable 71, which is linearly arranged at equal intervals and rotatably connected to both sides of the frame 4. The outer side of the turntable 71 is connected to the inner output end of the drive mechanism 6. A mounting rail 72 is fixedly mounted on the inner side of the turntable 71. A mounting block 73 is slidably connected inside the mounting rail 72. A fixing arm 74 is fixedly mounted on the inner side of the mounting block 73. A pressure roller 5 is fixedly mounted on the inner side of the mounting block 73. A limit module 75 is fixedly mounted on the bottom of the mounting rail 72. The limit module 75 and the mounting block 73 are engaged. During the application of this device, it is first realized through the mounting mechanism 7. For the assembly of the pressure roller 5 and the frame 4, the operator fixes the pressure roller 5 onto the fixing arm 74 inside the mounting block 73, and then slides the mounting block 73 into the mounting rail 72 inside the turntable 71. At this time, the limiting module 75 at the bottom of the mounting rail 72 engages with the mounting block 73, completing the stable installation of the pressure roller 5. This assembly process does not require complicated tools and can quickly complete the connection between the pressure roller 5 and the frame 4, providing convenience for the rapid start of subsequent leveling operations. When hot-rolled steel plate leveling is required, the drive mechanism 6 starts and transmits power to the outside of the mounting mechanism 7, driving the turntables on both sides inside the frame 4. 71 rotates, and during the rotation of turntable 71, the mounting rail 72, mounting block 73, and fixing arm 74 rotate synchronously, thereby causing the pressure roller 5 to rotate as well. Simultaneously, the electric push rod 3 inside the fixed seat 2 is activated, and its output end pushes the frame 4 to move. As the frame 4 moves, it drives the internal pressure roller 5 to adjust its position synchronously, allowing the pressure roller 5 to be adjusted to a suitable working state according to the leveling requirements of the steel plate. This ensures effective leveling of hot-rolled steel plates in different states, improving the adaptability of leveling operations. When the pressure roller 5 needs to be replaced due to wear, deformation, or other reasons after long-term use, the operator... Simply operate the limit module 75 to release its engagement with the mounting block 73, then slide the mounting block 73 out of the mounting rail 72 to remove the old pressure roller 5 from the frame 4. Then slide the mounting block 73 with the new pressure roller 5 fixed in it into the mounting rail 72 and lock it in place with the limit module 75 to complete the replacement of the pressure roller 5. The entire replacement process does not require disassembling the frame 4, the fixing seat 2, or other structures, which greatly shortens the replacement time of the pressure roller 5, reduces equipment downtime, and reduces the impact on production schedule. At the same time, it simplifies the operation process of pressure roller 5 maintenance and reduces the difficulty of operation for staff.

[0026] Combination Figures 1-4As shown, mounting brackets 8 are fixedly installed on both sides of the substrate 1. Mounting holes 9 are provided at both ends of the outer side of the mounting brackets 8. The mounting holes 9 are countersunk holes. The limiting module 75 includes a circular groove 751 and a locking hole 752. The circular groove 751 is located at the lower end of the mounting rail 72. A torsion spring 753 is fixedly connected inside the circular groove 751. A connecting plate 754 is fixedly installed on the outer side of the torsion spring 753 and movably connected to the inside of the circular groove 751. A circular block 755 is fixedly installed on the outer side of the turntable 71 and rotatably connected to the inner and outer ends of the circular groove 751. A limiting arm 756 is fixedly installed on one side of the circular block 755. Hole 752 is opened in the middle of mounting block 73 and on the upper end of mounting rail 72 near the limiting arm 756. The locking hole 752 is arc-shaped. An arc-shaped locking pin 757 is fixedly connected to the outer end of the limiting arm 756. The end of the arc-shaped locking pin 757 passes through the mounting rail 72 and is inserted into the locking hole 752 of mounting block 73. An adjusting handle 758 is fixedly connected to the side of round block 755 away from the limiting arm 756. A handle ball 759 is fixedly connected to the outer end of the adjusting handle 758. The top view of mounting rail 72 and mounting block 73 are both convex. The locking hole 752 and the arc-shaped locking pin 757 are both concentric with torsion spring 753.

[0027] In the above-described embodiments of this application, during the application of this device, it is first fixed as a whole by the mounting brackets 8 on both sides of the base plate 1. Workers then use the mounting holes 9 at both ends of the outer side of the mounting brackets 8 to fix the device at the designated work position using connectors. The mounting holes 9 are countersunk holes, allowing the head of the connector to be embedded in the hole, avoiding protrusion and interference with the operation of other components or the conveying of steel plates. This ensures the overall structural stability of the device after installation, simplifies the installation process, and improves the adaptability of the device to different work positions. When the pressure roller 5 is assembled via the mounting mechanism 7… The mounting rail 72 and mounting block 73 are arranged in a U-shape when viewed from above. The U-shape structure restricts the sliding direction of the mounting block 73, ensuring that the mounting block 73 slides stably along the mounting rail 72. When the mounting block 73 slides to the designated position, the limiting module 75 starts to work: the torsion spring 753 in the circular groove 751 remains in its natural state, driving the internal turntable 71 to a specific angle. The circular block 755 on the outside of the turntable 71 is positioned synchronously, so that the limiting arm 756 is in the locking position. At this time, the mounting block 73 is aligned with the locking hole 752 of the mounting rail 72, and the torsion spring 75... 3. The elastic force pushes the circular block 755 and the limiting arm 756 to rotate, allowing the arc-shaped locking pin 757 at the outer end of the limiting arm 756 to pass through the mounting rail 72 and insert into the locking hole 752 of the mounting block 73. The locking hole 752 and the arc-shaped locking pin 757 are both concentrically arranged with the torsion spring 753, ensuring precise engagement of the arc-shaped locking pin 757 and achieving a secure lock between the mounting block 73 and the mounting rail 72. This prevents the mounting block 73 from shifting when the pressure roller 5 rotates, ensuring the accuracy of the leveling operation. When the pressure roller 5 needs to be replaced and the locking needs to be released, the operator holds the outer end of the adjusting handle 758. The handrail ball 759 pulls the adjusting handrail 758, causing the round block 755 to rotate in the round groove 751. The round block 755 compresses the torsion spring 753, causing it to deform. At the same time, it drives the limit arm 756 to rotate, and the arc-shaped locking pin 757 is pulled out from the locking hole 752, quickly releasing the lock between the mounting block 73 and the mounting rail 72. Unlocking can be completed manually by simply operating the handrail without the need for complicated tools, simplifying the unlocking process, shortening the preparation time before replacing the pressure roller 5, further improving the replacement efficiency of the pressure roller 5, and reducing the impact of equipment downtime on production.

[0028] Example 2

[0029] Combination Figures 1-2 and Figure 4As shown, the drive mechanism 6 includes a side plate 61 and a worm gear 62. The side plate 61 is fixedly installed at both ends of one side of the frame 4. The drive assembly 63 is fixedly connected to the outer side of the side plate 61. The worm gear 64 is rotatably connected between the inner sides of the side plate 61. The worm gear 62 is rotatably connected to the side of the frame 4 near the side plate 61 with equal spacing and linear arrangement. The worm gear 62 and the worm gear 64 are connected in a transmission connection. The inner sides of the worm gear 62 and the worm gear 64 are fixedly connected to the outer side of the turntable 71. The drive assembly 63 includes a fixed plate 631 and a driven gear 632. The fixed plate 631 is fixedly installed on the outer side of the side plate 61. The drive motor 633 is fixedly installed on one side of the fixed plate 631. The output end of the drive motor 633 passes through the fixed plate 631 and is fixedly connected to the drive gear 634. The driven gear 632 is rotatably connected to the side of the side plate 61 near the driven gear 632. The drive gear 634 and the driven gear 632 are meshed together.

[0030] In the above-described embodiments of this application, during the application of this device, the drive mechanism 6 is activated when the pressure roller 5 needs to be driven to rotate. After the drive motor 633 in the drive assembly 63 is powered on, it outputs power. The power is transmitted to the drive gear 634 through the output end of the drive motor 633. The drive gear 634 drives the driven gear 632 to rotate through meshing. This meshing transmission method can achieve stable power transmission, avoid slippage during power transmission, and ensure power transmission efficiency. After the driven gear 632 rotates, it further drives the worm 64 between the inner sides of the side plates 61 to rotate. The worm 64 and the worm wheel 62 on the side of the frame 4 near the side plate 61 form a transmission connection. When the worm 64 rotates, it drives the worm wheel 62 to rotate synchronously. The worm wheels 62 are arranged linearly with equal spacing, which can ensure that each worm wheel 62 is subjected to uniform force and rotates synchronously, thereby making the rotation of the worm wheel 62 fixed to the inner side of the worm wheel 62 more efficient. The disc 71 maintains a consistent rotation rhythm, providing a foundation for the stable operation of the subsequent pressure roller 5. Throughout the power transmission process, the side plate 61 provides stable support for the worm 64, worm wheel 62, and drive assembly 63, while the fixing plate 631 fixes the drive motor 633, preventing displacement due to vibration during operation and ensuring the overall stable operation of the drive mechanism 6. Simultaneously, through the cooperation of the drive motor 633, the driving gear 634, the driven gear 632, the worm 64, and the worm wheel 62, power can be transmitted step by step and speed can be adjusted, enabling the pressure roller 5 to obtain a rotation speed suitable for the leveling requirements of different steel plates, improving the leveling effect on hot-rolled steel plates of different thicknesses and deformation degrees. Furthermore, the cooperation structure of each transmission component is simple, and the power transmission path is clear, making it easy for staff to quickly locate the problematic component when a transmission failure occurs, reducing maintenance difficulty.

[0031] The working principle and advantages of this utility model are as follows: Before using this device, the equipment must be installed and fixed. The base plate 1 of this device serves as the basic load-bearing component, supporting all upper structures such as the fixed base 2 and the mounting frame 8. The mounting frames 8 on both sides of the base plate 1 simultaneously serve as load-bearing and positioning components. Workers use bolts and other connectors to fix the entire mechanism to the designated position on the leveling machine through the mounting holes 9 opened at both ends of the outer side of the mounting frame 8. The mounting holes 9 are countersunk holes, allowing the heads of the connectors to be embedded in the holes, preventing the connectors from protruding and affecting the operation of other components or interfering with the steel plate, thus ensuring the overall structural stability of the mechanism after installation. Meanwhile, the base plate... The mounting brackets 8 and mounting holes 9 on both sides allow this device to be adapted to different models of leveling machine stations, improving installation flexibility and applicability, and providing a stable foundation for subsequent leveling operations and roller system replacement. After installation and fixing, the pressure roller 5 installation stage can begin. The turntables 71 rotatably connected on both sides inside the frame 4 of this device have mounting rails 72 fixed on their inner sides. The mounting rails 72 provide guidance and support for the installation of the pressure roller 5, and the mounting block 73 is slidably connected to the mounting rails 72. Both have a convex shape when viewed from above. This convex structure can restrict the sliding direction of the mounting block 73, allowing it to move only along the length of the mounting rails 72, effectively preventing the mounting block 73 from deviating. To move or detach from the mounting rail 72, the operator first connects the fixing arm 74, which holds the pressure roller 5, to the mounting block 73. Then, the mounting block 73 is slid into the mounting rail 72, achieving initial assembly of the pressure roller 5 and the turntable 71. When the mounting block 73 slides to the designated position, the limiting module 75 begins to operate: the circular groove 751 of the limiting module 75 is located at the lower end of the mounting rail 72, and a torsion spring 753 is fixed inside the circular groove 751. In its natural state, the torsion spring 753 drives the turntable 71 inside the circular groove 751 to maintain a specific angle, while the circular block 755 on the outside of the turntable 71 rotates synchronously with the turntable 71, so that the limiting arm 756 is in the locking position; the mounting block 73 and the mounting rail 72 are then engaged. After the clasp holes 752 are aligned, the torsion spring 753 returns to its original position, pushing the circular block 755 and the limiting arm 756 to move. This allows the arc-shaped locking pin 757 at the outer end of the limiting arm 756 to pass through the mounting rail 72 and insert into the clasp hole 752 of the mounting block 73. Both the clasp hole 752 and the arc-shaped locking pin 757 are concentric with the torsion spring 753 to ensure precise locking. This ultimately achieves stable installation of the pressure roller 5. This process requires no complicated operations, laying a structural foundation for the rapid replacement of the pressure roller 5 in the future. Furthermore, the cooperation between the mounting rail 72 and the mounting block 73, along with the locking of the limiting module 75, ensures the stability of the pressure roller 5 after installation, preventing deviation during subsequent operation and thus guaranteeing the leveling accuracy.

[0032] After the pressure roller 5 is installed, the leveling operation begins. When steel plate leveling is required, the drive mechanism 6 of this device is activated. The side plate 61 of the drive mechanism 6 is fixed to both ends of one side of the frame 4. The fixing plate 631 on the outer side of the side plate 61 provides mounting support for the drive motor 633. After the drive motor 633 is powered on, its output end drives the drive gear 634 to rotate. The drive gear 634 meshes with the driven gear 632, transmitting power to the driven gear 632. The driven gear 632 then drives the worm gear 64 between the inner sides of the side plate 61 to rotate. The worm gear 64 and the worm wheels 62 arranged at equal intervals on the side of the frame 4 near the side plate 61 are also present. The transmission connection causes the worm gear 62 to drive the inner fixed turntable 71 to rotate. The turntable 71 further drives the mounting rail 72, mounting block 73, and fixed arm 74 to rotate, causing the pressure roller 5 to rotate synchronously. During this process, the electric push rod 3 fixed inside the fixed seat 2 is activated synchronously, and its output end pushes the frame 4 to move horizontally. The frame 4 then drives the internal pressure roller 5 to move synchronously, thereby adjusting the distance and contact pressure between the pressure roller 5 and the steel plate to be leveled. This allows the pressure roller 5 to maintain a suitable working position according to the steel plate thickness and leveling requirements. When the hot-rolled steel plate to be leveled passes the rotating pressure roller 5, the pressure roller 5 directly contacts the steel plate, and through rotation and contact... Applying pressure to correct defects such as wavy deformation and overall twisting of steel plates, this device features a clear transmission path for its drive mechanism 6, with well-defined division of labor among its components and no redundant design. This not only simplifies the complex structure of traditional leveling machines and reduces manufacturing costs, but also allows the electric push rod 3 to adjust its position to meet the leveling needs of steel plates of different specifications. This avoids the problem of insufficient precision caused by the fixed position of the pressure roller 5, effectively ensuring the leveling effect. When the pressure roller 5 becomes worn, deformed, or damaged and needs to be replaced, the device enters the pressure roller 5 replacement stage. An adjusting handle 758 is fixed to the side of the circular block 755 of the limiting module 75 away from the limiting arm 756. A handrail ball 759 is fixed to the outer end of the hand 758. The handrail ball 759 is convenient for the staff to grip and apply force. The staff pulls and adjusts the handrail 758 by the handrail ball 759, which causes the round block 755 to rotate in the round groove 751. The round block 755 compresses the torsion spring 753 to deform it, and at the same time drives the limiting arm 756 to rotate, so that the arc-shaped locking pin 757 is pulled out from the locking hole 752 of the mounting block 73, releasing the locking between the mounting block 73 and the mounting rail 72. Then, the staff slides the mounting block 73 out along the length of the mounting rail 72. The mounting block 73 drives the fixing arm 74 and the old pressure roller 5 to be removed simultaneously, completing the disassembly of the old pressure roller 5.Next, the mounting block 73 with the new pressure roller 5 fixed on it is slid into the mounting rail 72. The locking steps of the limiting module 75 during the installation stage of the pressure roller 5 are repeated to complete the fixing of the new pressure roller 5. In the entire replacement process, this technical solution, through the design of the mounting mechanism 7 and the limiting module 75, does not require disassembling the entire leveling machine. Only the operation of the adjustment handle 758 is required to quickly install and remove the pressure roller 5, which greatly shortens the replacement time and reduces the downtime of the leveling machine. It effectively solves the problem that the replacement of the pressure roller 5 of the traditional leveling machine requires disassembling the entire machine, which is time-consuming. At the same time, because the structure of this device is simplified, the staff can quickly locate the faulty parts during daily maintenance and repair. For example, when the drive motor 633 fails, only the drive motor 633 needs to be repaired or replaced. There is no need to involve other unrelated parts, and no need for professional personnel to perform complicated whole-machine disassembly operations. This reduces the training cost of enterprises, shortens the maintenance cycle, and reduces maintenance costs, solving the problems of difficult maintenance and repair and high operating costs of traditional leveling machines.

This material has the characteristics of corrosion resistance, high strength, and strong weather resistance. The gear module is 2-5mm, and the number of teeth is 20-50. The parameters of the driving gear 634 and driven gear 632 are the same as those of the aforementioned gears. The worm gear 62 has a module of 2-5mm and 30-60 teeth. The worm 64 has 1-2 leads and a lead angle of 3°-15°. The gears, driving gear 634, driven gear 632, worm gear 62, and worm 64 can all be used for extended periods in air or water. The specific model and specifications of the electronic components are: drive motor 6... The Y2-132M-4 type three-phase asynchronous motor is selected for the 33, with a rated power of 2.2-5.5kW and a rated voltage of 380V. The electric push rod 3 is a DTZ300 type, with a rated thrust of 3000-5000N and a rated voltage of 220V.
