Description

Technical Field

[0001] This utility model relates to the field of material turning technology, specifically to a tilting device for casting. Background Technology

[0002] In modern casting production, the molding line process is a core link in ensuring casting quality and production efficiency. Its complete process covers key steps such as raw sand pretreatment, sand mixing, molding, solidifying the sand mold, mold assembly and pouring, sand removal, and old sand regeneration and recycling. Each link is closely connected and together constitutes the transformation chain of castings from raw materials to finished products. Among them, the sand treatment step after mold assembly and pouring has a significant impact on production continuity and the working environment.

[0003] In traditional molding lines, after the casting is poured, it enters a self-cooling stage via roller conveyors. Once the casting temperature drops to a suitable range, a robotic arm sequentially moves the upper and lower sand mold boxes to the sand removal machine table. The vibration of the sand removal machine separates the sand mold from the casting, completing the sand removal and part removal process. However, during this process, due to insufficient sealing of the sand mold during transport and the adjustment of the robotic arm's posture when grasping the sand mold, some sand inevitably spills from the gaps in the sand mold onto the surface of the casting base plate.

[0004] Current technology still predominantly relies on manual cleaning to remove scattered sand. Operators must enter the work area between production line breaks, using brooms, shovels, and other tools to collect the sand and transport it to a designated location. This method is labor-intensive, involves frequent cleaning, and is physically demanding, impacting production efficiency. Furthermore, the sand contains dust, which poses health risks with long-term inhalation, and the dust generated during cleaning further worsens the environment. A few companies use simple mechanical devices, but due to the uneven distribution and particle size of the sand, these only remove surface sand and cannot completely solve the problem. Utility Model Content

[0005] To address the technical problem of sand boxes scattering onto the surface of the casting base plate during the handling of parts by a robotic arm, which is difficult to clean, this utility model provides a tilting device for casting.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tilting device for casting includes a motorized roller conveyor mounted on top of a frame. The motorized roller conveyor includes several rotating rollers, each with its axial direction arranged in a horizontal transverse direction. Two clamping members are installed within the motorized roller conveyor, arranged in a horizontal transverse direction. The tops of the two clamping members pass through the gap between two adjacent rotating rollers, and the tops of the two clamping members can move towards each other or away from each other in the horizontal transverse direction. A base is provided at the bottom of the frame. One side of the bottom of the frame in the horizontal transverse direction is hinged to the base via a tilting shaft, the axial direction of which is arranged in a horizontal longitudinal direction. The other side of the bottom of the frame in the horizontal transverse direction is connected to the output end of a lifting mechanism. The lifting mechanism is mounted on the base, and its output end can drive the frame to rotate around the axis of the tilting shaft through a telescopic movement.

[0008] With the above structural design, the motorized roller conveyor can connect with the production line's roller conveyor. Utilizing the continuous operation of its rotating rollers, it achieves automated receiving and conveying of the cast-in-place slab, completing the material transfer process without manual intervention. The opposing or receding movements of the two clamping members in the horizontal direction precisely clamp and fix the cast-in-place slab transported to the motorized roller conveyor, ensuring that the slab will not shift or fall off during subsequent tilting. After the two clamping members clamp the cast-in-place slab, the lifting mechanism, through the extension and retraction of its output end, stably drives the frame to rotate around the tilting axis. The tilting angle can be adjusted according to actual cleaning needs, thoroughly tilting the scattered sand on the cast-in-place slab to a preset collection area, such as the scattered sand grid on site, achieving automated cleaning, replacing manual cleaning, reducing labor costs, and minimizing the harm of dust to personnel. Simultaneously, the collaborative working mode of the motorized roller conveyor, clamping members, and lifting mechanism can be integrated into the production line process, completing the cleaning operation without interrupting production, significantly improving cleaning efficiency and effectively ensuring production continuity.

[0009] As a preferred implementation of a tilting device for casting, each clamping element includes a clamping rod, and the top of each clamping rod is connected to a locking claw. The hook tips of the two locking claws are arranged opposite each other. The middle part of each clamping rod is hinged to the side wall of the motorized roller conveyor in the horizontal transverse direction through a hinge shaft one. The bottom of each clamping rod is provided with a corresponding telescopic component one, which is installed on the frame. The bottom of each clamping rod is hinged to the corresponding telescopic component one through a hinge shaft two. The telescopic component one can extend and retract in the horizontal transverse direction. The axial directions of both the hinge shaft one and the hinge shaft two are arranged in the horizontal longitudinal direction.

[0010] With the above structural design, the telescopic movement of the first telescopic component along the horizontal direction causes the clamping rod to rotate around the first hinge shaft, thereby driving the two locking claws to move towards or away from each other. Because the hook tips of the two locking claws are positioned opposite each other, they can firmly hook onto the side edge of the bottom of the casting base plate during the opposite movement, forming a stable clamping structure. Compared to traditional planar clamping, this method has a larger contact area and stronger clamping force, ensuring that the casting base plate will not loosen or fall off even when the frame tilts at a large angle, greatly improving the reliability of the clamping operation. Furthermore, both the first and second hinge shafts are positioned along the horizontal longitudinal direction, ensuring that the clamping rod does not shift laterally during rotation, further enhancing the stability and accuracy of the entire clamping mechanism.

[0011] As a preferred implementation of a tilting device for casting, the telescopic component is a hydraulic cylinder.

[0012] Adopting the above structural design, the telescopic component is a hydraulic cylinder. Utilizing the characteristics of hydraulic transmission, it provides stable and powerful power output. Its driving force is sufficient to drive the clamping rod to complete the rotation action quickly and accurately, ensuring sufficient clamping force of the locking hooks on the cast-in-place base plate. Even with heavy or uneven base plates, reliable clamping can be achieved. Simultaneously, the hydraulic cylinder has a fast response speed, and the telescopic range can be precisely adjusted through the hydraulic control system, thereby accurately controlling the clamping and releasing actions of the locking hooks, perfectly adapting to the fast-paced operation requirements of the production line. Furthermore, the hydraulic cylinder has good wear resistance and impact resistance, maintaining stable performance even under long-term, high-frequency working conditions, extending the service life of the equipment and reducing maintenance costs.

[0013] As a preferred implementation of a tilting device for casting, the lifting mechanism includes a telescopic component two, which includes an output end and a fixed end. The output end of the telescopic component two is hinged to the frame via a hinge shaft three, and the fixed end of the telescopic component two is hinged to the base via a hinge shaft four. The axial directions of the hinge shaft three and the hinge shaft four are both arranged along the horizontal longitudinal direction.

[0014] With the above structural design, the telescopic component two of the lifting mechanism is connected to the frame via hinge shaft three and to the base via hinge shaft four. This double-hinged design allows the telescopic component two to flexibly adapt to the rotation trajectory of the frame during extension and retraction, avoiding structural jamming or stress concentration. When the telescopic component two extends, its output end applies an upward thrust to the frame, driving the frame to rotate smoothly upward around the tilting shaft; when the telescopic component two retracts, it pulls the frame downward to reset. Throughout the process, the tilting angle of the frame can be precisely controlled by the extension and retraction of the telescopic component two, ensuring the smoothness and controllability of the tilting action. This effectively prevents sand from scattering into non-target areas due to violent shaking during tilting, improving the cleanliness of the cleaning operation.

[0015] As a preferred implementation of a tilting device for casting, the second telescopic component is a hydraulic cylinder.

[0016] Using the above structural design, the second telescopic component employs a hydraulic cylinder. With its powerful driving force and stable telescopic performance, it can easily tilt the frame carrying the movable roller conveyor, the pouring base plate, and the scattered sand, maintaining continuous operation even under heavy loads. The telescopic speed of the hydraulic cylinder can be precisely controlled via a flow control valve. Operators can adjust the tilting speed of the frame according to the sand's distribution and the weight of the base plate, ensuring that the sand slides evenly and thoroughly from the base plate to the collection area. Furthermore, the hydraulic transmission has excellent cushioning performance, effectively reducing impact when the frame tilts to its maximum angle or returns to a horizontal position, preventing damage to equipment components from violent collisions and extending the overall service life of the device.

[0017] As a preferred implementation of a tilting device for casting, a limit switch is provided on the top of the base. The limit switch can contact the bottom of the frame in a horizontal state. The telescopic component two includes an electromagnetic reversing valve, and the limit switch is electrically connected to the electromagnetic reversing valve.

[0018] With the above structural design, the electromagnetic directional valve, as the control core of the hydraulic system, can quickly switch the hydraulic circuit by receiving electrical signals to achieve start / stop and status locking control of the telescopic component two. When the frame returns to a horizontal state under the action of the telescopic component two, the bottom of the frame will contact the limit switch, which will then send an electrical signal to the electromagnetic directional valve. Upon receiving the signal, the electromagnetic directional valve will immediately cut off the oil inlet or outlet circuit of the telescopic component two, causing it to stop its extension and retraction and maintain its current state. This precisely limits the downward tilting position of the frame, preventing damage to the equipment due to collisions between the frame and the base or other components caused by excessive tilting. Therefore, this application achieves an automated limit protection mechanism, effectively protecting the equipment without manual monitoring, and significantly improving the safety and reliability of the device operation.

[0019] As a preferred implementation of a tilting device for casting, the top of the base is provided with a vertically arranged limiting post, the top of which can abut against the bottom of the frame in a horizontal state.

[0020] With the above structural design, the limiting post abuts against the bottom of the frame when it is in a horizontal position, further limiting the downward tilting position of the frame from a mechanical structural perspective, forming a double protection with the limit switch. When the frame returns to a horizontal position, the limiting post first supports the frame, distributing the pressure of the frame on the lifting mechanism and preventing fatigue damage caused by the lifting mechanism bearing full load for a long time, thus extending the service life of the lifting mechanism. At the same time, the limiting post also reduces the swaying of the frame in a horizontal position, enhancing the overall stability of the equipment. In addition, an elastic buffer pad can be installed at the top of the limiting post, which acts as a buffer when the frame tilts down, reducing the noise and impact force generated by mechanical collisions, further protecting the equipment components.

[0021] As a preferred implementation of a tilting device for casting, the bottom of the base is provided with a leveling mechanism, which includes several height adjustment components distributed at different positions on the bottom of the base.

[0022] With the above structural design, the leveling mechanism at the bottom of the base can adjust the height of various parts of the base individually through height adjustment components distributed at different locations. When the device is installed in an uneven environment, the operator can adjust the height adjustment components at the corresponding positions to keep the base level. This ensures that the frame and motorized roller conveyor installed on top of the base are in a level position, guaranteeing that the motorized roller conveyor can accurately connect with other roller conveyors on the production line. This avoids problems such as jamming, tilting, or falling of the cast base plate during transportation due to height differences, ensuring the stability of the cast base plate reception and transportation. At the same time, the existence of the leveling mechanism also expands the applicability of the device, enabling it to work normally in various complex ground environments.

[0023] As a preferred implementation of a tilting device for casting, several height adjusting components are arranged along the horizontal longitudinal direction. Each height adjusting component includes a support frame, the length direction of which is arranged along the horizontal transverse direction. Each support frame has a base frame at its bottom. Several adjusting screws are connected between each support frame and its corresponding base frame. The several adjusting screws are arranged along the horizontal transverse direction. Each adjusting screw is threadedly connected to its corresponding base frame. Each adjusting screw has an adjusting nut threadedly connected to its outer circumference.

[0024] With the above structural design, the adjusting screw in each height adjustment component is threadedly connected to the base frame. By rotating the adjusting nut, the extension length of the adjusting screw between the support frame and the base frame can be changed, thereby achieving fine adjustment of the support frame height. The adjustment method is simple to operate, highly accurate, and can meet the precise requirements of the base's levelness. Multiple adjusting screws are arranged in a horizontal direction, ensuring even force distribution on the support frame during height adjustment. This avoids deformation or damage to the support frame due to excessive force at a single point, improving the structural stability after leveling. Furthermore, the adjusting nut can lock itself after adjustment, preventing the adjusting screw from loosening due to vibration or other factors during equipment operation, ensuring the durability of the leveling effect.

[0025] As a preferred implementation of a tilting device for casting, several base frames are connected together by a connecting plate arranged in a horizontal longitudinal direction. The top of the connecting plate is provided with a vertically arranged extension rod, and the top of the extension rod is connected to a position sensor. The side of the support frame has a slot extending in a vertical direction, and the position sensor extends into the slot. The position sensor is electrically connected to an alarm.

[0026] With the above structural design, when the operator adjusts the height of the height adjustment component, if it is adjusted to its extreme position (such as the support frame being adjusted to its highest or lowest state), the top or bottom of the slot on the side of the support frame will contact the position sensor extending into the slot. The position sensor then sends an electrical signal to the alarm, which sounds an alarm through sound and light, promptly reminding the operator to stop the current adjustment operation. This avoids problems such as the adjusting screw detaching from the support frame or base frame, or damage to components due to over-adjustment. This enhances the equipment's self-protection capability, reduces equipment maintenance costs caused by operational errors, and also ensures the safety of the leveling operation process, ensuring that operators can promptly detect and correct improper operations.

[0027] The beneficial effects of this utility model include:

[0028] The motorized roller conveyor in this invention can connect with the roller conveyor of the production line. Through the continuous operation of its rotating rollers, it enables automated receiving and conveying of the cast-in-place base plate, completing the material transfer process without manual intervention. The opposing or back-to-back movement of the two clamping members in the horizontal direction precisely clamps and fixes the cast-in-place base plate transported to the motorized roller conveyor, ensuring that the base plate will not shift or fall off during subsequent tilting. After the two clamping members clamp the cast-in-place base plate, the lifting mechanism, through the extension and retraction of its output end, stably drives the frame to rotate around the tilting axis. The tilting angle can be adjusted according to actual cleaning needs, thoroughly tilting the scattered sand on the cast-in-place base plate to a preset collection area, such as a sand grating on site, achieving automated cleaning, replacing manual cleaning, reducing labor costs, and minimizing the harm of dust to the human body. Simultaneously, the collaborative working mode of the motorized roller conveyor, clamping members, and lifting mechanism can be integrated into the production line process, completing the cleaning operation without interrupting production, significantly improving cleaning efficiency and effectively ensuring production continuity.

[0037] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] In the molding line process of casting production, from the pretreatment of raw sand to the recycling of old sand, the sand treatment after casting has a significant impact on production continuity and the working environment. After the casting has completed self-cooling, the sand box is transferred to the sand removal machine by the robot arm, which achieves the separation of sand mold and casting. However, during this process, due to insufficient sealing of the sand box during transfer and the adjustment of the robot arm's posture, some sand inevitably falls onto the surface of the casting base plate 014.

[0039] Existing methods for cleaning up loose sand have significant drawbacks: traditional manual cleaning requires operators to enter the work area between production line intervals and use brooms, shovels, and other tools to collect and transport the sand. This is not only labor-intensive and costly, but also affects production efficiency due to frequent cleaning. Furthermore, sand contains dust, which is harmful to health if inhaled over a long period, and the dust generated during cleaning further deteriorates the working environment. The simple mechanical devices used by a few companies can only remove surface sand due to uneven sand distribution and particle size differences, failing to completely solve the problem.

[0040] Therefore, this embodiment proposes a tilting device for casting, which aims to achieve efficient and thorough cleaning of sand scattered on the casting base plate through automated structural design.

[0041] Reference Figure 1-5A casting tilting device includes a motorized roller conveyor 1, which is a commercially available structure. The motorized roller conveyor 1 is installed on the top of a frame 2 and includes several rotating rollers 11. The axial direction of each rotating roller 11 is arranged in a horizontal transverse direction. Two clamping members 3 are installed inside the motorized roller conveyor 1 and are arranged in a horizontal transverse direction. Each clamping member 3 includes a clamping rod 31, and the top of each clamping rod 31 is connected to a locking hook 32. The hooks of the two locking hooks 32 are... The clamping rods 31 are arranged with their tips facing each other. The middle part of each clamping rod 31 is hinged to the side wall of the motorized roller conveyor 1 in the horizontal transverse direction via a hinge shaft 33. Each clamping rod 31 has a corresponding telescopic component 7 at its bottom. The telescopic component 7 is a hydraulic cylinder and is mounted on the frame 2. The bottom of each clamping rod 31 is hinged to the corresponding telescopic component 7 via a hinge shaft 34. The telescopic component 7 can extend and retract in the horizontal transverse direction. The axial directions of the hinge shaft 33 and the hinge shaft 34 are both arranged in the horizontal longitudinal direction. The locking claws 32 at the top of the two clamping components 3 pass through the gap between the two adjacent rotating rollers 11. The two locking claws 32 can move towards each other or away from each other in the horizontal transverse direction under the drive of the corresponding telescopic component 7. The clamping force is amplified by the lever principle, thereby clamping or releasing the casting base plate 014 entering the motorized roller conveyor 1. (Refer to...) Figure 3 , Figure 3 Only one locking claw 32 is shown. When clamped, the locking claw 32 can hook onto the side edge of the bottom of the casting base plate 014. This embodiment can clamp casting base plates 014 of different thicknesses or with uneven surfaces. Figure 4 The arrow X in the diagram indicates the direction in which rack 2 flips upwards.

[0042] The bottom of the frame 2 is provided with a base 4. The bottom of the frame 2 is hinged to the base 4 on one side in the horizontal direction via a flip shaft 5. The axial direction of the flip shaft 5 is set along the horizontal longitudinal direction.

[0043] The bottom of the frame 2 is connected to the output end 611 of the lifting mechanism 6 on the other side of the horizontal direction. The lifting mechanism 6 is mounted on the base 4. The lifting mechanism 6 includes a telescopic component 61, which is a hydraulic cylinder. The telescopic component 61 includes an output end 611 and a fixed end 612. The output end 611 of the telescopic component 61 is hinged to the frame 2 through a hinge shaft 62. The fixed end 612 of the telescopic component 61 is hinged to the base 4 through a hinge shaft 63. The axial directions of the hinge shafts 62 and 63 are both set along the horizontal longitudinal direction. The output end 611 of the telescopic component 61 can drive the frame 2 to rotate around the axis of the flipping shaft 5 through telescopic movement.

[0044] The base 4 is equipped with a limit switch 8 at the top. The limit switch 8 can contact the bottom of the frame 2 in a horizontal state. The telescopic component 61 includes an electromagnetic reversing valve. The limit switch 8 is electrically connected to the electromagnetic reversing valve. When the limit switch 8 contacts the bottom of the frame 2, it indicates that the frame 2 has tilted down to the limit position. The limit switch 8 will send an electrical signal to the electromagnetic reversing valve. After receiving the signal, the electromagnetic reversing valve can cut off the oil inlet or return line of the telescopic component 61, so that the telescopic component 61 stops its telescopic movement and maintains its current state, avoiding damage to the equipment caused by excessive tilting of the frame 2. This achieves automated limit protection and improves the safety of the device operation.

[0045] The base 4 has a vertically positioned limiting post 9 at its top, the top of which can abut against the bottom of the frame 2 in a horizontal state. An elastic element can be provided at the top of the limiting post 9 to cushion the downward tilt of the frame 2.

[0046] The base 4 has a leveling mechanism at its bottom, which includes several height adjustment components 10 distributed at different positions on the bottom of the base 4. The height adjustment components 10 are arranged in a horizontal longitudinal direction, and each height adjustment component 10 includes a support frame 101. The length direction of the support frame 101 is arranged in a horizontal transverse direction, and the bottom of each support frame 101 has a base frame 102. Several adjusting screws 103 are connected between each support frame 101 and its corresponding base frame 102. The adjusting screws 103 are arranged in a horizontal transverse direction, and each adjusting screw 103 is threadedly connected to its corresponding base frame 102. An adjusting nut 104 is threadedly connected to the outer circumference of each adjusting screw 103.

[0047] Several base frames 102 are connected by a connecting plate 011 arranged horizontally. The top of the connecting plate 011 has a vertically arranged extension rod 012, and the top of the extension rod 012 is connected to a position sensor 013. The side of the support frame 101 has a slot 1011 extending vertically, and the position sensor 013 extends into the slot 1011. The position sensor 013 is electrically connected to an alarm. When the adjusting nut 104 is rotated, changing the length of the adjusting screw 103 between the support frame 101 and the base frame 102, thereby raising or lowering the support frame 101, when the support frame 101 is raised or lowered to its limit position, the position sensor 013 will contact the bottom or top of the slot 1011, sending a signal to the alarm, which then sounds an alarm to alert personnel.

[0048] Work process:

[0049] After the production line completes the part removal operation, the cast base plate 014, containing loose sand, is conveyed by the production line roller conveyor to the motorized roller conveyor 1 of this device. The rotating rollers 11 of the motorized roller conveyor 1 start synchronously, and by matching the speed with the production line roller conveyor, smoothly convey the cast base plate 014 to the preset clamping position. At this time, the position sensors (not shown in the figure) installed on both sides of the motorized roller conveyor 1 detect the arrival signal of the cast base plate 014, and then send a command to the control system to trigger the clamping action.

[0050] Upon receiving the signal, the two telescopic components 7 extend synchronously in the horizontal direction. Their piston rods push the clamping rod 31 to rotate upward around the hinge shaft 33 via the hinge shaft 34. Since the hook tips of the two locking claws 32 are set opposite each other and their tops pass through the gap between the rotating rollers 11, the locking claws 32 will hook onto the two sides of the bottom of the casting base plate 014 in the horizontal direction. After the locking claws 32 are fully engaged, the telescopic component 7 stops moving and maintains pressure to ensure that the casting base plate 014 will not be displaced during the subsequent tilting process, thus preventing the casting base plate 014 from falling off during the subsequent tilting.

[0051] After clamping, the control system sends a tilting command to the telescopic component 61 of the lifting mechanism 6. The output end 611 of the telescopic component 61 begins to slowly extend, applying an upward thrust to the frame 2 through the hinge shaft 62. Since one side of the frame 2 is hinged to the base 4 through the tilting shaft 5, the entire frame 2 will rotate upward around the tilting shaft 5. During the rotation, the fixed end 612 of the telescopic component 61 rotates relative to the base 4 through the hinge shaft 63, avoiding mechanical interference. The tilting angle of the frame 2 can be preset by the control system or adjusted in real time according to the amount of sand scattered. Specifically, when the angle sensor (not shown in the figure) installed on the side of the frame 2 detects the preset angle, the telescopic component 61 stops extending, keeping the frame 2 in a tilted state. Those skilled in the art should be familiar with the principle, installation method, and usage of the angle sensor. At this time, the loose sand on the cast base 014 slides down the surface of the base plate under the action of gravity. It can be guided to the loose sand grid by the sand guide plate (not shown in the figure) preset on one side of the base 4, so as to realize automated centralized collection, reduce labor costs and reduce the health hazards of dust to workers.

[0052] After the tilting operation has continued for a preset time, the control system instructs the telescopic component 61 to retract, causing the frame 2 to slowly return to its horizontal position. As the bottom of the frame 2 gradually approaches a horizontal position, it first contacts the elastic buffer pad at the top of the limit post 9. The buffer pad absorbs the impact force through its own deformation, reducing mechanical wear. Subsequently, the bottom of the frame 2 fully presses against the limit switch 8. The limit switch 8 immediately sends an electrical signal to the solenoid directional valve of the telescopic component 61. The solenoid directional valve switches the oil circuit, stopping the telescopic component 61 and locking its current state, ensuring that the frame 2 remains stably horizontal. The limit post 9 and the limit switch 8 provide dual protection, preventing the frame 2 from overturning and damaging the equipment, and also reducing the load-bearing pressure on the telescopic component 61.

[0053] Finally, the control system commands the telescopic component 7 to retract, and the piston rod pulls the clamping rod 31 downward around the hinge shaft 33 via the hinge shaft 34. The locking hook 32 then disengages from the casting base plate 014 and retracts into the gap between the rotating rollers 11. After the locking hook 32 has fully reset, the motorized roller conveyor 1 restarts, transporting the cleaned casting base plate 014 to the connected production line roller conveyor, completing one full cleaning cycle.

[0054] If the device is installed on uneven ground, it can be calibrated using a leveling mechanism: the operator uses a spirit level to check the levelness of the base 4. For low-lying areas, rotate the adjusting nut 104 of the corresponding height adjusting component 10 to extend the adjusting screw 103 upwards along the base frame 102, thereby raising the support frame 101; conversely, rotate the adjusting nut 104 to retract the adjusting screw 103, lowering the height of the support frame 101. During leveling, if the top or bottom of the slot 1011 of the support frame 101 touches the position sensor 013, the sensor immediately triggers an alarm (such as an audible and visual alarm) to remind the operator to stop adjusting, preventing the adjusting screw 103 from detaching from the support frame 101 or causing damage to the component due to over-adjustment. After leveling, the adjusting nut 104 is tightly fitted with the base frame 102, locking the position of the adjusting screw 103 through friction, preventing height deviation due to vibration during equipment operation.

[0055] The control system mentioned in this embodiment can be automatic control or manual control via an operating system.
