Description

Technical Field

[0001] This invention relates to the field of stacker technology, specifically to a stacking device for processing grid filter plates. Background Technology

[0002] As a core component in environmental water treatment, chemical filtration, and municipal water supply and drainage, the production of bar screens involves multiple processes, including forming, cutting, and surface treatment. Material transfer and finished product stacking between these processes heavily rely on the stacking equipment in the aisle. The operational stability of the stacking equipment directly determines the transfer efficiency and product yield of the bar screens. The stability of the walking system and the loading status are crucial elements for ensuring the reliable operation of the stacking equipment.

[0003] Existing roadway stacking devices generally use a traveling structure with wheels and tracks. Under long-term heavy loads and high-frequency reciprocating operation, the wheel surfaces are prone to wear and rounding defects, dents, and hardened scars formed by the adhesion of processing debris and oil. These defects cause regular vibrations during equipment movement, exacerbating wear on the tracks and wheel sets, and even causing equipment deviation. At the same time, the bar screens are mostly stacked sheet structures. Misalignment during stacking and inertial slippage during transfer can cause the center of gravity of the load to shift, further amplifying the vibration amplitude of the equipment. In severe cases, this can cause the plates to slip and break, and the stacking device to jam and stop, affecting the operating efficiency of the entire processing production line.

[0004] To address the aforementioned potential hazards, the industry currently employs two main monitoring methods: one is a manual, periodic inspection mode, relying on maintenance personnel to visually inspect the wear condition of the wheels and verify the stacking position of goods. This method has low detection efficiency and poor real-time performance, making it difficult to identify minor wheel surface defects and slight center of gravity shifts in the early stages. Fault detection is generally delayed, and bar screen processing warehouses are often characterized by high dust levels, narrow spaces, and dense equipment layouts, making manual inspections labor-intensive and posing safety risks. The other method is a purely electronic sensor monitoring solution, which uses vibration and displacement sensors installed on the equipment to collect operating signals to identify anomalies. However, these electronic components are poorly adapted to the high humidity, dust, and oil conditions of warehouses, are susceptible to environmental interference causing signal drift, and have a high rate of false alarms and missed alarms. Furthermore, sensor calibration and maintenance costs are high, and the fault diagnosis and replacement process is complex, making long-term stable operation difficult.

[0005] In addition, existing stacking devices with mechanical detection structures generally have limited functions, and most can only detect wear on the traveling wheels, failing to simultaneously cover faults such as cargo center of gravity shift. Furthermore, existing mechanical detection structures lack sensitivity to detect minor disturbances and are unable to filter interference caused by accidental factors such as track joints and instantaneous bumps, resulting in a high false trigger rate. This makes it impossible to meet the high-precision and high-reliability operation monitoring requirements in the processing of grid filter panels. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as defects in the traveling wheels of stacking devices, abnormal vibrations caused by the offset of the center of gravity of the load, poor reliability, easy false alarms and missed alarms, and delayed fault identification of traditional detection methods. Therefore, this invention proposes a stacking device with a grid filter plate.

The first rack is located in the middle of the inner side of the bracket. The first rack extends slidably into the inner cavity of the connecting frame in the front-back direction. The first rack has an impact cavity in the front-back direction. The detection wheel is rotatably sleeved on the outer side of the bracket through a bearing. The outer wall of the detection wheel is in contact with the outer wall of the walking wheel. The alarm component is located in the inner cavity of the connecting frame.

[0009] Furthermore, the inner cavity of the impact chamber is fitted with an impact ball that can roll.

[0010] Furthermore, the impact ball can roll relative to the impact cavity by its own inertia when the stacker crane body jerks or swings back, and apply additional force to the first rack by impacting the front and rear walls of the impact cavity, thereby amplifying the reciprocating stroke of the first rack.

The second spring is embedded in the inner cavity of the support box, and one end of the second spring is engaged with the inner wall of the support box. The top end of the pawl is slidably fitted into the inner cavity of the support box, and the bottom end of the pawl slidably extends out of the bottom end of the support box. The other end of the second spring is engaged with the top end of the pawl. The two pawls are respectively matched with the first ratchet and the second ratchet.

[0014] Furthermore, the first ratchet and its corresponding pawl, and the second ratchet and its corresponding pawl, respectively form two sets of unidirectional transmission pairs, which can convert the reciprocating linear motion of the first rack into the unidirectional continuous rotation of the third connecting rod, and count the number of fault disturbances in an accumulated manner, filtering out single accidental vibration interference.

[0015] Further, the execution unit includes: a second gear, a fourth connecting rod, a third gear, a slider, a second guide rod, a second rack, a moving groove, and a third spring.

[0016] Furthermore, the execution unit also includes: a screw, a sensing plate, and a proximity switch.

The sensing plate is slidably fitted into the inner cavity of the moving slot and screwed to the outer wall of the screw. The proximity switch is located on the right side of the mounting box, and the position of the proximity switch corresponds to the position of the sensing plate. The proximity switch and the sensing plate are matched.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This device adopts a contact-type follow-up detection structure. Through the close contact between the detection wheel and the traveling wheel, it can simultaneously monitor wheel damage faults such as out-of-roundness of the traveling wheel, wheel surface dents, and surface scars, as well as abnormal vehicle body jerking and swaying caused by the shift of the center of gravity of the loaded vehicle. There is no need to set up two separate detection systems. Under the premise of simplifying the equipment structure, it covers two common operational hazards of stacker crane traveling system and loading status, making it convenient for maintenance personnel to fully control the equipment operation status.

[0018] 2. On one hand, the first rack has an impact chamber and an impact ball inside, which can amplify the displacement signal by means of the inertia of the vehicle body during speed change, improve the ability to identify weak disturbances such as slight off-center load and small wheel surface defects, and reduce the probability of missed fault detection. On the other hand, the unidirectional transmission structure composed of two sets of ratchet pawls can convert reciprocating disturbances into unidirectional continuous cumulative action, which can filter out accidental interferences such as single track joint bumps and instantaneous external force impacts, effectively reduce the probability of false alarms, and make the detection results more reliable.

[0019] 3. This invention uses a purely mechanical transmission structure as the core detection carrier and only uses a proximity switch at the end to output an alarm signal. Compared with a purely electronic sensing and monitoring scheme, it has a higher tolerance to harsh warehouse environments such as dust, high humidity, and oil stains in the grid filter plate processing scenario. It is less prone to problems such as component failure and signal drift, has better long-term operational stability, and is less affected by environmental interference.

[0020] 4. This invention can drive the induction plate to move up and down along the moving groove by rotating the screw, which can flexibly adjust the alarm trigger threshold. The detection accuracy can be matched according to the actual conditions such as the specifications of the goods, the running speed, and the track conditions on site, and adapt to different operation requirements. After the fault is cleared, the detection mechanism can be reset by separating the second rack and the third gear. The operation is simple, no complicated calibration is required, and the normal operation of the equipment can be quickly restored.

[0021] 5. This invention can trigger an early warning in the early stages of a fault, making it easier for maintenance personnel to repair defects in the traveling wheels and correct the center of gravity of the stacked goods in a timely manner. This reduces damage to the grid filter plate caused by abnormal vibration of the equipment. At the same time, it can reduce the additional wear on the traveling wheels and tracks caused by abnormal loads, extend the service life of key components to a certain extent, and reduce subsequent maintenance costs.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Reference Figures 1-12A stacking device for processing grid filter plates includes: a stacker body 1, a drive motor 2, a detection mechanism 3, anti-collision rubber heads 4, guide wheels 5, a rotating rod 6, and traveling wheels 7. The stacker body 1 is existing technology and will not be described in detail here. The stacker body 1 serves as the load-bearing base for the entire machine, used to carry the grid filter plate stacks and various functional components to complete the transfer and storage of goods. There are two drive motors 2, which are screwed to the rear right side and front left side of the stacker body 1, respectively. The drive motors 2 provide power to the traveling wheels 7, driving the rotating rod 6 and traveling wheels 7 through output torque, thus enabling the stacker to move as a whole. There are two detection mechanisms 3, which are respectively located at the bottom of the front and rear sides of the stacker body 1. The detection mechanisms 3 are core fault monitoring units that can detect defects in the traveling wheels 7 and the offset of the load center of gravity in real time, triggering an alarm when abnormalities occur. The anti-collision rubber heads 4... Located at the outer top of the detection mechanism 3, the anti-collision rubber head 4 acts as a buffer to prevent hard collisions between the stacker crane and surrounding components during operation. There are four guide wheels 5, which are respectively located at the bottom outer left and right ends of the two detection mechanisms 3. The guide wheels 5 are used to limit and guide the movement trajectory of the stacker crane to prevent the equipment from deviating in the aisle and to ensure the stability of the walking route. The rotating rod 6 is locked to the output end of the drive motor 2 through a coupling. The rotating rod 6 can rotatably extend into the inner cavity of the detection mechanism 3. The left and right sides of the outer wall of the rotating rod 6 are rotatably set on the left and right sides of the inner cavity of the detection mechanism 3 through bearings. The rotating rod 6 is used to receive the power of the drive motor 2 and transmit it. It achieves stable rotation by relying on the bearings and is used to synchronously drive the walking wheel 7 to rotate. The walking wheel 7 is fixedly sleeved in the middle of the outer wall of the rotating rod 6. The walking wheel 7 is located in the inner cavity of the detection mechanism 3. The walking wheel 7 rolls in contact with the aisle track and drives the entire stacker crane to move along the track by its own rotation.

[0027] Specifically, the detection mechanism 3 includes: a mounting frame 31, a first guide rod 32, a bracket 33, a first spring 34, a first rack 35, an impact chamber 36, a detection wheel 38, an alarm component 39, and a connecting frame 310. There are two connecting frames 310, which are respectively located at the bottom of the front and rear sides of the stacker crane body 1. The connecting frame 310 serves as a transition mounting base, fixing the detection mechanism 3 to the bottom of the stacker crane body and providing support and positioning for various components. The mounting frame 31 is located on the outside of the connecting frame 310. The anti-collision rubber head 4 is located at the top of the outside of the mounting frame 31. The guide wheel 5 is located on the outside of the bottom end of the mounting frame 31. The left and right sides of the outer wall of the rotating rod 6 are rotatably mounted on the left and right sides of the inner cavity of the mounting frame 31 via bearings. The wheel 7 is located inside the mounting frame 31, which is the main frame of the detection mechanism 3. It integrates and mounts components such as the wheel 7, guide wheel 5, and anti-collision rubber head 4, while also providing assembly space for internal sliding and transmission components. There are four first guide rods 32, with their inner ends respectively located on the left and right sides of the inner cavities of the two mounting frames 31. The first guide rods 32 are sliding guide components that limit the movement trajectory of the bracket 33, ensuring that the bracket 33 can only perform stable linear reciprocating motion. There are two brackets 33, with their left and right sides slidably and appropriately fitted onto the outer walls of the four first guide rods 32. The brackets 33 support the detection wheel 38 and the first rack 35, and can slide along the first guide rods 32 synchronously. The first spring 34 is sleeved on the outer wall of the first guide rod 32 to transmit the displacement signal collected by the detection wheel 38. One end of the first spring 34 is engaged with the inner wall of the mounting bracket 31, and the other end of the first spring 34 is engaged with the outer wall of the bracket 33. The first spring 34 is a rotary spring, which undergoes elastic deformation after being compressed or stretched by external force. When the external force is removed or it returns to its initial state, the first spring 34 is normally kept in a compressed state, continuously pushing the bracket 33 so that the detection wheel 38 is always in close contact with the surface of the traveling wheel 7, ensuring continuous and reliable signal acquisition. The first rack 35 is set in the middle of the inner side of the bracket 33. The first rack 35 extends slidably into the inner cavity of the connecting frame 310 in the front-back direction. The first rack 35 has an impact cavity 36 in the front-back direction. The first rack 35 follows the bracket. Synchronous sliding of rack 33 transmits linear displacement to the rear transmission structure. Impact ball 37 is rollably fitted into the inner cavity of impact chamber 36. Using its own inertia, impact ball 37 rolls and impacts the cavity wall within impact chamber 36, amplifying the travel distance of the first rack 35 under center-of-gravity offset conditions and improving detection sensitivity. Detection wheel 38 is rotatably sleeved on the outer side of bracket 33 via bearings. The outer wall of detection wheel 38 contacts the outer wall of traveling wheel 7, ensuring the detection wheel 38 always adheres to the outer edge of traveling wheel 7. It picks up abnormal signals such as surface defects of traveling wheel 7 and relative displacement of the vehicle body in real time, completing physical quantity acquisition. Alarm component 39 is located in the inner cavity of connecting frame 310. Alarm component 39 receives the motion signal transmitted by the first rack 35, and triggers an alarm after transmission and counting.Remind maintenance personnel to troubleshoot equipment malfunctions.

[0028] Specifically, the alarm component 39 includes: a mounting box 391, a guide groove 392, a rotating unit 393, and an execution unit 394. The mounting box 391 is located inside the mounting bracket 31. The guide groove 392 is provided on the right side of the mounting box 391 along the vertical direction. The mounting box 391 serves as the overall protection and mounting base for the alarm component 39, and is used to accommodate the internal transmission components. The rotating unit 393 is located in the inner cavity of the mounting box 391. The rotating unit 393 is used to convert the linear motion transmitted by the first rack 35 into unidirectional continuous rotational motion to complete the accumulation of fault frequency. The execution unit 394 is located on the right side of the mounting box 391. The execution unit 394 is used to receive the power of the rotating unit 393 and convert the rotational motion back into linear motion, which, together with the sensing component, achieves the final alarm trigger.

[0029] Specifically, the rotating unit 393 includes: a first connecting rod 3931, a first gear 3932, a first bevel gear 3933, a second connecting rod 3934, a second bevel gear 3935, a third connecting rod 3936, a third bevel gear 3937, a first ratchet 3938, a second ratchet 3939, a support box 39310, a second spring 39311, and a pawl 39312.

The first gear 3932 is fitted with... The first connecting rod 3931 is attached to the outer wall of the first connecting rod 3931 and locked by a set screw. The first gear 3932 meshes with the first rack 35. The first gear 3932 is used to convert the linear displacement of the first rack 35 into rotational motion, realizing the initial power conversion. The first bevel gear 3933 is sleeved on the right side of the outer wall of the first connecting rod 3931 and locked by a set screw. The first bevel gear 3933 is located in the inner cavity of the mounting box 391. The first bevel gear 3933 is used to change the power transmission direction and output torque to the second bevel gear 3935. The second connecting rod 3934 is rotatably set at the bottom end of the inner cavity of the mounting box 391 through a bearing. The second connecting rod 3934 is an intermediate transmission carrier, supporting the operation of the second bevel gear 3935 and completing the power transfer. 3935 is sleeved on the outer wall of the second connecting rod 3934 and locked by a set screw. The second bevel gear 3935 meshes with the first bevel gear 3933. The second bevel gear 3935 receives the power from the first bevel gear 3933 and reverses direction again, transmitting torque to the third bevel gear 3937. The third connecting rod 3936 is rotatably mounted on the right side of the inner cavity of the mounting box 391 via a bearing. The right end of the third connecting rod 3936 rotatably extends out of the right side of the mounting box 391. The third connecting rod 3936 is the end-drive output shaft, receiving power and maintaining unidirectional rotation, outputting continuous rotational action outward. The third bevel gear 3937 is rotatably sleeved on the outer wall of the third connecting rod 3936 via a bearing. The third bevel gear 3937 and the second bevel gear 3934 mesh. The third bevel gear 3937 engages with the second bevel gear 3935 to complete multi-stage reversing transmission and stably transmit rotational power. The first ratchet 3938 is sleeved on the left side of the outer wall of the third connecting rod 3936 and locked by a set screw. The first ratchet 3938 is located in the inner cavity of the first bevel gear 3933. The first ratchet 3938 engages with the corresponding pawl 39312 to achieve unidirectional transmission and restrict the reverse rotation of the third connecting rod 3936. The second ratchet 3939 is sleeved on the middle of the outer wall of the third connecting rod 3936 and locked by a set screw. The second ratchet 3939 is located in the inner cavity of the third bevel gear 3937. The second ratchet 3939 works in conjunction with the first ratchet 3938 to further enhance the unidirectional transmission effect and ensure that the drive shaft always rotates in the same direction.There are two support boxes 39310, which are respectively disposed on the inner walls of the first bevel gear 3933 and the third bevel gear 3937. The support boxes 39310 provide installation and movement space for the second spring 39311 and the pawl 39312. The second spring 39311 is embedded in the inner cavity of the support box 39310, and one end of the second spring 39311 is engaged with the inner wall of the support box 39310. The second spring 39311 is a rotary spring, which undergoes elastic deformation after being compressed or stretched by external force, and returns to its initial state when the external force is removed. The second spring 39311 is used to support the pawl 39312. 12 provides elastic clamping force to ensure that pawl 39312 always contacts the ratchet, guaranteeing unidirectional meshing transmission. The top end of pawl 39312 is slidably fitted into the inner cavity of support box 39310, and the bottom end of pawl 39312 slidably extends out of the bottom end of support box 39310. The other end of the second spring 39311 is engaged with the top end of pawl 39312. The two pawls 39312 are respectively matched with the first ratchet 3938 and the second ratchet 3939. Under the action of the second spring 39311, pawl 39312 engages with the ratchet, driving the ratchet to rotate unidirectionally. During reverse movement, it automatically slips out and idles.

[0030] Specifically, the execution unit 394 includes: a second gear 3941, a fourth connecting rod 3942, a third gear 3943, a slider 3944, a second guide rod 3945, a second rack 3946, a moving groove 3947, a third spring 3948, a screw 3949, a sensing plate 39410, and a proximity switch 39411. The second gear 3941 is sleeved on the right side of the outer wall of the third connecting rod 3946 and locked by a set screw. The second gear 3941 is located on the right side of the mounting box 391. The second gear 3941 is used to transmit rotational power outward and cooperate with the lower gear to complete the speed change transmission. The fourth connecting rod 3942 is rotatably mounted on the right side of the mounting box 391 through a bearing, serving as a support shaft and providing mounting for the third gear 3943. Positioning ensures smooth gear operation. The third gear 3943 is sleeved on the outer wall of the fourth connecting rod 3942 and locked by a set screw. The third gear 3943 meshes with the second gear 3941. The number of teeth on the outer wall of the second gear 3941 is several times the number of teeth on the outer wall of the third gear 3943. The meshing of the third gear 3943 and the second gear 3941 amplifies the rotational stroke by utilizing the difference in the number of teeth, driving the subsequent second rack 3946 to perform linear motion. The slider 3944 is slidably fitted into the inner cavity of the guide groove 392. The inner cavity of the guide groove 392 is dovetail-shaped. The slider 3944 is limited by the guide groove 392, causing the rear end component to slide smoothly along a fixed trajectory. There are two second guide rods 3945. The second guide rod 3945 is respectively located at the upper and lower ends of the right side of the slider 3944 to provide sliding guidance for the second rack 3946, constrain its movement direction, and prevent deviation or jamming. The upper and lower sides of the second rack 3946 are respectively slidably matched with the outer walls of the two second guide rods 3945. The second rack 3946 and the third gear 3943 mesh. The outer side of the second rack 3946 has a moving groove 3947 along the vertical direction. The second rack 3946 is used to convert the rotational motion into vertical linear motion, driving the sensing component to move synchronously. The third spring 3948 is sleeved on the outer wall of the second guide rod 3945. One end of the third spring 3948 is engaged with the outer wall of the second rack 3946. The other end of the third spring 3948... The end is engaged with the outer wall of the second guide rod 3945. The third spring 3948 is a rotary spring that undergoes elastic deformation after being compressed or stretched by external force, and returns to its initial state after the external force is removed. The third spring 3948 is used to push the second rack 3946 to always mesh with the third gear 3943. The top end of the screw 3949 is rotatably set at the top end of the inner cavity of the moving groove 3947 through a bearing. The bottom end of the screw 3949 rotatably extends out of the bottom end of the second rack 3946. When the screw 3949 rotates, it can drive the sensing plate 39410 to move up and down to adjust the position of the sensing plate 39410. The sensing plate 39410 is slidably fitted into the inner cavity of the moving groove 3947 and screwed to the outer wall of the screw 3949.The sensing plate 39410 rises and falls synchronously with the second rack 3946, serving as the trigger carrier. When it approaches the proximity switch 39411, it triggers an alarm. The proximity switch 39411 is located on the right side of the mounting box 391, and its position corresponds to that of the sensing plate 39410. The proximity switch 39411 and the sensing plate 39410 are matched. The proximity switch 39411 is existing technology and will not be described in detail here. After sensing the sensing plate 39410, the proximity switch 39411 outputs an electrical signal, sending an alarm notification to the control panel to remind maintenance personnel to handle the fault.

[0031] The working principle is as follows: Step 1: The main body 1 of the stacker crane is used to carry goods with grid filter plates. The drive motor 2 drives the rotating rod 6 to rotate continuously through the coupling. The traveling wheel 7, which is fixedly sleeved in the middle of the rotating rod 6, rotates synchronously and rolls along the aisle track to achieve uniform speed movement of the stacker crane as a whole. The anti-collision rubber head 4 plays a role in anti-collision protection. The guide wheel 5 plays a role in guiding and preventing the stacker crane from deviating. The detection mechanism 3 moves synchronously with the main body 1 of the stacker crane. Step 2: Under normal conditions, the first spring 34 is always in a compressed state, continuously pushing the bracket 33 outward. Under the pre-tightening thrust of the first spring 34, the outer wall of the detection wheel 38 is always tightly attached to the outer wall of the walking wheel 7, ensuring that the detection wheel 38 can pick up the radial deformation and relative displacement of the walking wheel surface in real time during the rotation of the walking wheel 7. Step 3: When the stacker crane's center of gravity is centered, the traveling wheels 7 are intact, and the stacker crane starts and stops smoothly and travels at a constant speed, the acceleration of the stacker crane body 1 is extremely small. The impact ball 37 only moves slightly inside the impact cavity 36 and cannot hit the front and rear walls of the impact cavity 36. It will not exert additional thrust on the first rack 35. Even if the impact ball 37 hits the front and rear walls of the impact cavity 36, the impact force generated is extremely small and insufficient to overcome the preload of the first spring 34. As a result, the first rack 35 will not be displaced. At the same time, the radial dimension of the outer edge of the traveling wheel 7 is uniform and will not exert a reciprocating pushing effect on the detection wheel 38. The bracket 33 and the first rack 35 remain stationary as a whole, and the monitoring mechanism is in normal standby state. Step 4: When the grid filter plates carried by the stacker crane are not stacked neatly and the center of gravity shifts, the overall force on the equipment is uneven, both front-to-back and left-to-right. The load on the two traveling wheels 7 is different, and the amount of wheel compression deformation is different, resulting in inconsistent rolling linear speeds of the coaxial traveling wheels 7. The stacker crane's travel resistance fluctuates continuously. At the same time, the grid filter plate stack is not rigidly bound, and the plates will slip slightly due to inertia during travel, further aggravating the center of gravity shift. In addition, the traveling wheels 7 are subjected to lateral extrusion force, and the load changes repeatedly when passing through track joints and height differences, ultimately causing intermittent failure of the stacker crane body 1. Irregular forward and backward jerking and vehicle body swaying: When the stacker crane body 1 jerks and sways, the contact point between the traveling wheel 7 and the rail is briefly locked by static friction, creating a momentary blockage. However, the stacker crane body 1 and the detection mechanism 3 fixed to it have a large overall mass and strong inertia, and do not stop synchronously with the traveling wheel 7, continuing to move forward with their original motion trend. Because the traveling wheel 7 is an elastic structure, there is an assembly clearance in the wheel bearing, and the connecting metal parts can also undergo slight elastic deformation. During the brief pause of the traveling wheel 7 and the continued forward movement of the stacker crane body 1, the elastic structure is compressed, and the fitting clearance... Displacement occurs, causing a minute, imperceptible relative motion between the traveling wheel 7 and the stacker crane body 1. After the resistance disappears, the elastic structure rebounds and returns to its initial relative position. This relative displacement directly acts on the tightly fitted traveling wheel 7 and detection wheel 38, pushing the detection wheel 38 to drive the bracket 33 to slide back and forth along the first guide rod 32. The bracket 33 simultaneously drives the first rack 35 to reciprocate linearly. During the repeated speed changes and jerks of the vehicle body, the first rack 35 continuously accelerates and decelerates with the stacker crane body 1. The impact balls 37 in the impact chamber 36 rely on their own... Due to inertia, the impact ball 37 rolls backward relative to the first rack 35. When the vehicle body moves forward, the impact ball 37 rolls backward and hits the rear wall of the impact chamber 36, providing additional backward thrust to the first rack 35. When the vehicle body bounces back, the impact ball 37 rolls forward and hits the front wall of the impact chamber 36. Combined with the rebound force of the first spring 34, it pushes the first rack 35 to reset. With the help of the inertial impact of the impact ball 37, the reciprocating stroke of the first rack 35 is effectively amplified, which makes up for the problem of insufficient basic displacement under the condition of center of gravity offset, and significantly improves the detection sensitivity of the device for center of gravity offset faults. Step 5: After the first rack 35 generates a linear displacement, the first gear 3932 meshing with the first rack 35 rotates accordingly. The first gear 3932 drives the first bevel gear 3933 to rotate synchronously through the first connecting rod 3931. When the first rack 35 moves inward, it can cause the first gear 3932 to rotate clockwise. When the first gear 3932 drives the first bevel gear 3933 to rotate clockwise through the first connecting rod 3931, the first bevel gear 3933 can then drive the pawl 39312 in its inner cavity to rotate clockwise through the support box 39310 in its inner cavity, thereby utilizing... The engagement between the pawl 39312 and the first ratchet 3938 drives the third connecting rod 3936 to rotate clockwise. Simultaneously, the clockwise rotation of the first bevel gear 3933 drives the third bevel gear 3937 to rotate counter-clockwise via the second bevel gear 3935. The counter-clockwise rotation of the third bevel gear 3937 utilizes the clockwise rotation of the second ratchet 3939 to compress the counter-clockwise rotating pawl 39312, causing the pawl 39312, which matches the second ratchet 3939, to move into the inner cavity of the support box 39310 and compress the second spring 39311, causing elastic deformation. This ensures the stability of the third connecting rod 3936. 936 can rotate clockwise smoothly; when the first rack 35 moves outward, it can cause the first gear 3932 to rotate counterclockwise. When the first gear 3932 drives the first bevel gear 3933 to rotate counterclockwise through the first connecting rod 3931, it can drive the pawl 39312 in its inner cavity to rotate counterclockwise. When the pawl 39312 rotates counterclockwise around the third connecting rod 3936 as the central axis, it can slide along the outer wall of the first ratchet 3938, and the first ratchet 3938 can squeeze the pawl 39312 to move into the inner cavity of the support box 39310. Simultaneously, the second spring 39311 is compressed, causing elastic deformation. The first bevel gear 3933 rotates counterclockwise, which in turn drives the third bevel gear 3937 to rotate clockwise via the second bevel gear 3935. The clockwise rotation of the third bevel gear 3937 in turn drives the pawl 39312 in its inner cavity to rotate clockwise via the support box 39310 in its inner cavity. Thus, the cooperation between the pawl 39312 and the second ratchet 3939 drives the third connecting rod 3936 to rotate clockwise, thereby ensuring that the third connecting rod 3936 can rotate clockwise regardless of the direction in which the first rack 35 moves. Step Six: When the third connecting rod 3936 rotates clockwise, it drives the second gear 3941 to rotate clockwise. The clockwise rotation of the second gear 3941 drives the third gear 3943 to rotate counterclockwise. The counterclockwise rotation of the third gear 3943 drives the second rack 3946 to move the sensing plate 39410 upward. When the stacker crane's center of gravity shift fault persists, the impact ball 37 repeatedly amplifies the displacement, causing the second rack 3946 to continuously move the sensing plate 39410 upward until the proximity switch 39411 senses the sensing plate 39410. At this time, the proximity switch 39411 sends a signal to the central control console to issue an alarm. Step 7: After the fault is cleared, pull the second rack 3946 to the right. The second rack 3946 slides to the right along the outer wall of the second guide rod 3945 and compresses the third spring 3948 to undergo elastic deformation until the second rack 3946 and the third gear 3943 separate. The second rack 3946 drives the slider 3944 to slide down along the guide groove 392 through the second guide rod 3945 until it slides to the initial position. Release the second rack 3946. Under the elastic force of the third spring 3948, the second rack 3946 can be pushed to the left until the second rack 3946 meshes with the third gear 3943 again. Step 8: Since the second gear 3941 will rotate clockwise regardless of the direction in which the first rack 35 moves, this design adopts an cumulative detection method to filter out interference caused by single accidental vibrations and avoid false alarms. Step 9: The operator can rotate the screw 3949. The rotational force generated by the rotation of the screw 3949 can cause the sensing plate 39410 to slide up and down along the inner cavity of the moving groove 3947, thereby adjusting the position of the sensing plate 39410 in the moving groove 3947, thereby adjusting the alarm trigger threshold to adapt to different detection accuracy requirements. Step 10: This device can also detect defects such as out-of-roundness of the traveling wheel 7, flat spots and pits on the wheel surface, and hardened scars of sawdust and grease adhering to the wheel surface. When there are uneven defects on the surface of the traveling wheel 7, the traveling wheel 7 will directly push the detection wheel 38 radially during rotation, causing the bracket 33 and the first rack 35 to move back and forth in a regular manner. The subsequent transmission, counting, and alarm processes are consistent with the center of gravity offset working condition. After the fault is cleared, all parts return to their initial positions, and the device re-enters the detection standby state.

[0032] In summary, this device can simultaneously detect two types of faults: damage to the traveling wheels and deviation of the cargo center of gravity. It has strong resistance to environmental interference, high sensitivity, and false alarm prevention characteristics. It is accurate in detection and convenient in operation and maintenance, effectively ensuring the stable and uniform operation of the stacker crane and reducing the damage and loss of the grid filter plate. Compared with traditional manual inspection and pure electronic monitoring solutions, it has stronger overall practicality.
