Description

Technical Field

[0001] This invention relates to the field of material transportation technology, and in particular to a method and equipment for detecting full load. Background Technology

[0002] Currently, most coal transportation in the market uses six-axle semi-trailers. GB1589 stipulates that the total mass requirement for six-axle semi-trailers is 49t, of which the curb weight is about 16t. This means that according to regulations, it can carry about 33t of coal. Therefore, how to control the loading capacity of six-axle semi-trailers is a concern for many coal yards.

[0003] In existing technologies, the full-load detection of material transport vehicles such as six-axle semi-trailers utilizes radar mounted on the roof to measure the height of materials such as coal piled below. Specifically, this full-load detection equipment uses radar to emit electromagnetic waves that illuminate the coal or other materials and receives their echoes, thereby obtaining the distance from the materials to the radar and calculating the height of the piled materials. However, electromagnetic waves are easily affected by external environmental interference, especially in environments with a lot of water mist or dust, where the path of the electromagnetic waves is easily blocked, affecting the detection accuracy of the radar and directly leading to uncontrolled loading of the transport vehicle.

[0004] Therefore, this application provides a full-load detection method and a full-load detection device to address the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a full-load detection method to alleviate the technical problem that the accuracy of full-load detection of transport vehicles is easily affected by external environmental interference in the prior art.

[0006] The present invention also aims to provide a full load detection device to further alleviate the technical problem that the accuracy of full load detection of transport vehicles is easily affected by external environmental interference in the prior art.

[0007] Based on the aforementioned first objective, the present invention provides a full-load detection method, utilizing the detection device of a full-load detection equipment, the full-load detection method comprising:

[0008] Step 1: The vehicle stops at the initial loading position, and the detection device moves to the preset full-load height inside the vehicle compartment;

[0009] Step two: Material begins to fall from the location corresponding to this loading position inside the carriage, thus forming a material pile inside the carriage and increasing the height of the material pile;

[0010] Step 3: When the height of the material pile inside the carriage reaches the detection device, it contacts the detection device. At this time, the material stops falling at the location corresponding to this loading position inside the carriage, and the vehicle stops at the next loading position.

[0011] Step four: Repeat steps two and three until loading is completed at the rear of the carriage.

[0012] Furthermore, the full load detection method is carried out in the loading channel, and the full load detection equipment is installed in the loading channel;

[0013] Step one includes: the vehicle drives into the loading channel, and the detection device of the fully loaded detection equipment rises so that the height of the detection device is higher than the height of the upper edge of the carriage;

[0014] The vehicle continues to travel to the initial loading position and stops. At the same time, the detection device moves horizontally to the top of the carriage and then descends, so that the detection device penetrates into the carriage to the preset full load height.

[0015] Furthermore, the full-load detection method also includes a fifth step set after step four:

[0016] The detection device rises to a height higher than the top edge of the carriage; the detection device moves horizontally to its initial position while the vehicle leaves the loading channel.

[0017] By adopting the above technical solution, the full-load detection method of the present invention has the following beneficial effects:

[0018] According to regulations, the cargo compartment of a transport vehicle can only carry a specific weight of material, which is the maximum material load, and cannot be exceeded. For example, a six-axle semi-trailer can legally carry a maximum of about 33 tons of coal. Overloading will cause overloading and material spillage, resulting in waste, while underloading will directly reduce transportation revenue. Therefore, loading the vehicle with the maximum material load is optimal. The maximum loading height after the material is loaded into the cargo compartment can be calculated from the maximum material load, which is the preset full load height inside the cargo compartment. As the detection device moves to the preset full load height inside the cargo compartment, the material falling into the cargo compartment increases the height of the material pile until it contacts the detection device, at which point the maximum material load in the cargo compartment is reached.

[0019] Additionally, it should be noted that when the vehicle reaches the initial loading position, material can be discharged from the corresponding location inside the truck bed. Similarly, when the vehicle reaches the next loading position, material can be discharged from the corresponding location inside the truck bed. For example, when material is discharged into the truck bed using a discharge device, as the vehicle reaches the initial loading position, the truck bed moves below the discharge device, and the location inside the truck bed corresponding to the initial loading position is opposite to the discharge device, allowing the discharge device to discharge material from that location. When the vehicle continues to the next loading position, the truck bed remains below the discharge device, but the location inside the truck bed corresponding to the next loading position is now opposite to the discharge device, allowing the discharge device to discharge material from that location.

[0020] The full-load detection method in this embodiment involves stopping the vehicle at the initial loading position to facilitate loading of materials into the corresponding initial loading position within the truck bed. A detection device is then moved to a preset full-load height within the truck bed to monitor the maximum material stacking height. Based on this, material is dropped into the truck bed to load materials into the corresponding initial loading position, forming a material pile that gradually increases in height. When the pile reaches the detection device, it contacts the device, indicating that the maximum material load has been reached at the initial loading position. At this point, dropping material into the corresponding initial loading position is stopped, for example, by shutting down the dropping equipment or by moving the vehicle away from the initial loading position, thus completing the first round of dropping.

[0021] The vehicle then starts and moves to the next loading position and stops to allow material to be loaded into the corresponding loading position in the cargo compartment. Material is then dropped into the cargo compartment to load the corresponding loading position, forming a material pile that gradually increases in height. When the height of the material pile reaches the detection device, it makes contact with the device. At this point, the amount of material loaded at the corresponding loading position in the cargo compartment reaches its maximum. Then, the dropping of material into the corresponding loading position in the cargo compartment stops, completing the second round of material dropping.

[0022] By repeating steps two and three once or multiple times, materials are loaded into multiple loading positions in the carriage in sequence until the loading is completed at the rear of the carriage. At this point, the entire carriage is fully loaded, and the height of the materials in each part of the carriage reaches the preset full load height, that is, the amount of materials loaded in the carriage reaches the maximum.

[0023] In summary, the full-load detection equipment of this embodiment achieves maximum material loading by sequentially loading multiple loading positions within the vehicle compartment, with the material height at each loading position being a preset full-load height. The material height at each loading position is controlled by a detection device. Before loading, the detection device is positioned at the preset full-load height within the vehicle compartment. This device serves as a marker for the full-load height; contact between the material pile and the detection device indicates that the pile height has reached its maximum, eliminating the need for further material loading at that position. Therefore, this embodiment's full-load detection method monitors the material pile height by direct contact between the material and the detection device, replacing the existing method of using radar to emit electromagnetic waves. This eliminates the need for an intermediate measurement medium for electromagnetic waves, thus preventing interference from the external environment and mitigating the technical problem in existing technologies where the accuracy of full-load detection for transport vehicles is easily affected by external environmental interference.

[0024] Based on the second objective mentioned above, the present invention provides a full-load detection device for implementing the full-load detection method. The full-load detection device includes a detection device and a moving device connected to the detection device, wherein the moving device is capable of moving the detection device.

[0025] Furthermore, the detection device includes a bracket connected to the mobile device and a rotating wheel mounted on the bracket and capable of rotating relative to the bracket, which can contact the rotating wheel when the height of the material pile inside the carriage increases.

[0026] Furthermore, the detection device also includes a drive motor mounted on the bracket, the drive motor driving the rotating wheel to rotate; or, the rotating wheel is an electric wheel.

[0027] Furthermore, a protective cover is fixed on the rotating wheel, and blades are provided on the circumferential surface of the protective cover. Multiple blades are provided, and the multiple blades are spaced apart along the circumferential direction of the protective cover.

[0028] Furthermore, the mobile device includes a first lifting mechanism and a rotating mechanism, wherein the first lifting mechanism is driven and connected to the rotating mechanism, and the detection device is connected to the rotating mechanism;

[0029] The rotating mechanism can drive the detection device to rotate in the horizontal direction, and the first lifting mechanism can drive the rotating mechanism to lift, thereby lifting the detection device.

[0030] Furthermore, the first lifting mechanism includes a column, a driving component, and a transmission assembly, with the driving component mounted on the column; the rotating mechanism includes a connecting frame and an electric rotating platform mounted on the connecting frame, with the detection device connected to the electric rotating platform, and the electric rotating platform capable of driving the detection device to rotate in the horizontal direction;

[0031] The driving component is connected to the connecting frame through the transmission assembly. The driving component can drive the connecting frame to rise and fall through the transmission assembly, thereby the connecting frame drives the detection device to rise and fall through the electric rotary table.

[0032] Furthermore, the first lifting mechanism also includes a guide rail installed on the column and a guide wheel locked on the guide rail. The guide wheel is installed on the connecting frame. When the connecting frame is raised or lowered, the connecting frame drives the guide wheel to move along the guide rail. A first limiting stop and a second limiting stop are respectively provided at both ends of the guide rail for limiting the connecting frame.

[0033] And / or, a first limit switch and a second limit switch are respectively provided at both ends of the column, and the connecting frame is provided with a trigger plate that can trigger the first limit switch and the second limit switch.

[0034] Furthermore, the full-load detection equipment also includes a cantilever device, which includes a cantilever beam and a second lifting mechanism installed on the cantilever beam;

[0035] Along the length of the cantilever beam, one end of the cantilever beam is connected to the rotating mechanism, and the other end is connected to the detection device through the second lifting mechanism, which can drive the detection device to rise and fall.

[0036] By adopting the above technical solution, the full-load detection device of the present invention has the following beneficial effects:

[0037] By using the full-load detection method with the aforementioned full-load detection equipment, the full-load detection equipment has all the advantages of the aforementioned full-load detection method, which will not be elaborated here. Attached Figure Description

[0054] Example 1

[0055] Please see Figure 1 This embodiment provides a full-load detection method, which utilizes the detection device 1 of a full-load detection equipment. The full-load detection method includes:

[0056] Step 1: The vehicle stops at the initial loading position, and the detection device 1 moves to the preset full-load height inside the truck bed. Step 2: Material begins to fall from the corresponding loading position inside the truck bed, forming a material pile and increasing its height. Step 3: When the height of the material pile inside the truck bed reaches the detection device 1, it contacts the detection device 1. At this point, material falling from the corresponding loading position inside the truck bed stops, and the vehicle stops at the next loading position. Step 4: Repeat steps 2 and 3 until loading is completed at the rear of the truck bed.

[0057] It should be noted that, according to regulations, the cargo compartment of a transport vehicle can only carry a specific weight of material as its maximum load, and this weight cannot be exceeded. For example, a six-axle semi-trailer can legally carry a maximum of approximately 33 tons of coal. Overloading will cause over-loading and material spillage, resulting in waste, while underloading will directly reduce transportation revenue. Therefore, loading the maximum material load is optimal. The maximum loading height after the material is loaded into the cargo compartment can be calculated from the maximum material load, which is the preset full load height inside the cargo compartment. As the detection device 1 moves to the preset full load height inside the cargo compartment, the material falling into the cargo compartment increases the height of the material pile inside the cargo compartment until it contacts the detection device 1, at which point the maximum material load in the cargo compartment is reached.

[0058] Additionally, it should be noted that when the vehicle reaches the initial loading position, material can be discharged from the corresponding location inside the truck bed. Similarly, when the vehicle reaches the next loading position, material can be discharged from the corresponding location inside the truck bed. For example, when material is discharged into the truck bed using a discharge device, as the vehicle reaches the initial loading position, the truck bed moves below the discharge device, and the location inside the truck bed corresponding to the initial loading position is opposite to the discharge device, allowing the discharge device to discharge material from that location. When the vehicle continues to the next loading position, the truck bed remains below the discharge device, but the location inside the truck bed corresponding to the next loading position is now opposite to the discharge device, allowing the discharge device to discharge material from that location.

[0059] The full-load detection method in this embodiment involves stopping the vehicle at the initial loading position to facilitate loading materials into the corresponding initial loading position within the truck bed. The detection device 1 moves to a preset full-load height within the truck bed to monitor the maximum material stacking height. Based on this, material is dropped into the truck bed to load materials into the corresponding initial loading position, forming a material pile that gradually increases in height. When the pile reaches the detection device 1, it contacts the device, indicating that the maximum material load has been reached at the initial loading position. At this point, dropping material into the corresponding initial loading position is stopped, for example, by shutting down the dropping equipment or by moving the vehicle away from the initial loading position, thus completing the first round of dropping.

[0060] Then the vehicle starts and drives to the next loading position and stops to allow material to be loaded into the corresponding loading position in the truck bed. At this time, material is dropped into the truck bed to load the corresponding loading position, so that a material pile can be formed in the truck bed and the height of the material pile gradually increases. When the height of the material pile reaches the detection device 1, it can contact the detection device 1. At this time, the amount of material loaded in the truck bed at the corresponding loading position reaches the maximum amount of material. Then, the dropping of material in the truck bed at the corresponding loading position stops, completing the second round of dropping.

[0061] By repeating steps two and three once or multiple times, materials are loaded into multiple loading positions in the carriage in sequence until the loading is completed at the rear of the carriage. At this point, the entire carriage is fully loaded, and the height of the materials in each part of the carriage reaches the preset full load height, that is, the amount of materials loaded in the carriage reaches the maximum.

[0062] In summary, the full-load detection equipment of this embodiment achieves maximum material loading by sequentially loading multiple loading positions within the vehicle compartment, with the material height at each loading position being a preset full-load height. The control of the material height at each loading position is achieved through a detection device 1. Before loading, the detection device 1 is positioned at the preset full-load height within the vehicle compartment. The detection device 1 serves as a marker for the full-load height of the vehicle compartment; contact between the material pile and the detection device 1 indicates that the pile height has reached its maximum, eliminating the need for further material loading at that position. Therefore, the full-load detection method of this embodiment monitors the material pile height by direct contact between the material and the detection device 1, replacing the existing method of using radar to emit electromagnetic waves. This eliminates the need for an intermediate measurement medium for electromagnetic waves, thus preventing interference from the external environment and mitigating the technical problem in existing technologies where the accuracy of full-load detection of transport vehicles is easily affected by external environmental interference.

[0063] Additionally, it should be noted that by changing the position of the preset full-load height inside the carriage, the purpose of quantitative loading of the carriage can be achieved.

[0064] The full load detection method is carried out in the loading channel, and both the unloading equipment and the full load detection equipment are set up in the loading channel.

[0065] Preferably, step one includes: the vehicle drives into the loading channel, the detection device 1 fully loaded with detection equipment rises, so that the height of the detection device 1 is higher than the upper edge of the carriage; the vehicle continues to drive to the initial loading position and stops, while the detection device 1 moves horizontally to the top of the carriage, and the detection device 1 descends, so that the detection device 1 extends into the carriage to the preset full load height.

[0066] With this setup, vehicle loading and full-load detection are both completed within the loading lane. In this embodiment, the full-load detection method involves raising the detection device 1 so that its height is higher than the top edge of the vehicle compartment. This ensures that the detection device 1 does not interfere with the movement of the vehicle compartment as it continues to travel, allowing the compartment to move below the detection device 1. The detection device 1 then moves horizontally to the vehicle compartment, positioning itself above it. Finally, the detection device 1 descends, penetrating deep into the compartment and lowering to a preset full-load height, which serves as the calibration height for material stacking within the compartment.

[0067] Preferably, a light curtain (existing technology, not described in detail here) is installed in the loading channel. The light curtain can measure the height of the vehicle's cargo compartment. The height value of the cargo compartment is transmitted to the detection device 1, so that the detection device 1 can be controlled to rise so that the height of the detection device 1 is higher than the upper edge of the cargo compartment.

[0068] Preferably, in this embodiment, the full load detection method further includes a fifth step after step four: the detection device 1 is raised so that the height of the detection device 1 is higher than the height of the upper edge of the carriage; the detection device 1 moves horizontally to the initial position, and at the same time the vehicle drives out of the loading channel, thus completing the loading of this vehicle, and the next vehicle begins to drive into the loading channel to load materials.

[0069] In this embodiment, the full-load detection method raises the detection mechanism so that the height of the detection device 1 is higher than the upper edge of the carriage, so that the vehicle will not interfere with the detection device 1 when it continues to drive; the detection device 1 is moved horizontally to the initial position to reset it for loading of the next loading vehicle.

[0070] Example 2

[0071] Example 2 provides a full-load detection device for implementing the full-load detection method of Example 1. The technical features of the full-load detection method disclosed in Example 1 are also applicable to this example, and the technical features of the full-load detection method disclosed in Example 1 will not be described again. The implementation of the full-load detection device will be further described in detail below with reference to the accompanying drawings.

[0072] Please see Figure 1 The full-load detection equipment provided in this embodiment includes a detection device 1 and a moving device connected to the detection device 1. The moving device can drive the detection device 1 to move.

[0073] This setup involves moving the detection device 1 via a mobile device, so that the detection device 1 can be moved to a preset full-load height inside the carriage, which serves as the calibration height for material stacking inside the carriage.

[0074] Preferably, please refer to Figure 5In this embodiment, the detection device 1 includes a bracket 11 connected to the moving device and a rotating wheel 12 installed on the bracket 11 and capable of rotating relative to the bracket 11. When the height of the material pile inside the carriage increases, it can contact the rotating wheel 12.

[0075] With this setup, the moving device can drive the rotating wheel 12 to move via the bracket 11. Furthermore, when material begins to fall into the carriage, the electric wheel rotates. When the height of the material pile inside the carriage increases to the point where the pile can contact the rotating wheel 12, the rotating wheel 12 experiences frictional resistance from the pile, causing a change in its torque. In other words, when the torque of the rotating wheel 12 changes, it indicates that the material has reached its maximum pile height, and the falling of material can be stopped.

[0076] Preferably, the detection device 1 further includes a drive motor mounted on the bracket 11, which drives the rotating wheel 12 to rotate; or, the rotating wheel 12 is an electric wheel.

[0077] With this setup, when the drive motor starts and drives the rotating wheel 12 to rotate, or when the electric wheel starts, the torque of the rotating wheel 12 changes when the height of the material pile inside the carriage increases to the point where the material pile can contact the rotating wheel 12. This changes the current of the drive motor or electric wheel. The change in current indicates that the material has reached the maximum stacking height. By monitoring the above data, it is possible to identify that the material has been stacked to the required height. At this point, an alarm message can be issued, indicating that the material has been detected and the material feeding can be stopped.

[0078] Preferably, please refer to Figure 5 In this embodiment, a protective cover 13 is fixed on the rotating wheel 12; blades 14 are provided on the circumferential surface of the protective cover 13, and multiple blades 14 are provided, with the multiple blades 14 spaced apart along the circumferential direction of the protective cover 13.

[0079] Preferably, multiple blades 14 are evenly arranged along the circumference of the protective cover 13.

[0080] With this configuration, the rotation of the rotating wheel 12 drives the protective cover 13 and the blades 14 to rotate together. The protective cover 13 protects the rotating wheel 12, preventing wear and extending its service life. The rotating blades 14 create a sliding motion on the material they contact, preventing the rotating wheel 12 from slipping, increasing its climbing ability, and preventing it from being buried by falling material.

[0081] Preferably, please refer to Figure 1In this embodiment, the mobile device includes a first lifting mechanism 2 and a rotating mechanism 3. The first lifting mechanism 2 drives and connects to the rotating mechanism 3, and the detection device 1 is connected to the rotating mechanism 3. The rotating mechanism 3 can drive the detection device 1 to rotate in the horizontal direction, and the first lifting mechanism 2 can drive the rotating mechanism 3 to lift and lower, thereby making the detection device 1 lift and lower.

[0082] In this setup, in step one, the transport vehicle enters the loading channel and the first lifting mechanism 2 drives the rotating mechanism 3 to rise, thereby the rotating mechanism 3 drives the detection device 1 to rise, so that the height of the detection device 1 is higher than the upper edge of the carriage; the vehicle continues to drive to the initial loading position and stops, while the rotating mechanism 3 drives the detection device 1 to rotate horizontally to the top of the carriage, so that the detection device 1 can be inserted into the carriage.

[0083] Preferably, please refer to Figure 1 and combined Figure 2 and Figure 3 In this embodiment, the first lifting mechanism 2 includes a column 21, a driving component 22, and a transmission assembly. The driving component 22 is mounted on the column 21. The rotating mechanism 3 includes a connecting frame 31 and an electric rotating platform 32 mounted on the connecting frame 31. The detection device 1 is connected to the electric rotating platform 32, and the electric rotating platform 32 can drive the detection device 1 to rotate in the horizontal direction. The driving component 22 is connected to the connecting frame 31 through the transmission assembly. The driving component 22 can drive the connecting frame 31 to rise and fall through the transmission assembly, so that the connecting frame 31 drives the detection device 1 to rise and fall through the electric rotating platform 32.

[0084] Optionally, the drive unit 22 is a lifting motor, and the transmission component can be a gear transmission component, a chain 23 transmission component, or a belt transmission component, etc.

[0085] Preferably, please refer to Figure 3 In this embodiment, the transmission assembly includes a sprocket (not shown) and a chain 23. The sprocket is fixedly connected to the output shaft of the lifting motor, and the chain 23 is meshed with the sprocket. The connecting frame 31 is also fixedly connected to the chain 23. With this configuration, the lifting motor can drive the sprocket to rotate when started, thereby the sprocket drives the connecting frame 31 to rise and fall via the chain 23, ultimately realizing the lifting and falling of the electric rotary table 32 and the detection device 1 mounted on the connecting frame 31.

[0086] Optionally, the first lifting mechanism 2 further includes a guide rail 24 mounted on the column 21 and a guide wheel 25 locked on the guide rail 24. The guide wheel 25 is mounted on the connecting frame 31. When the connecting frame 31 is raised or lowered, the connecting frame 31 drives the guide wheel 25 to move along the guide rail 24. The two ends of the guide rail 24 are respectively provided with a first limit stop 26 and a second limit stop 27 for limiting the connecting frame 31. Alternatively, the two ends of the column 21 are respectively provided with a first limit switch 28 and a second limit switch 29, and the connecting frame 31 is provided with a trigger plate 33 that can trigger the first limit switch 28 and the second limit switch 29.

[0087] Preferably, please refer to Figure 3 and Figure 6 In this embodiment, the first lifting mechanism 2 further includes a guide rail 24 installed on the column 21 and a guide wheel 25 locked on the guide rail 24. The guide wheel 25 is installed on the connecting frame 31. When the connecting frame 31 is lifted, the connecting frame 31 drives the guide wheel 25 to move along the guide rail 24. The two ends of the guide rail 24 are respectively provided with a first limit stop 26 and a second limit stop 27 for limiting the connecting frame 31. The two ends of the column 21 are respectively provided with a first limit switch 28 and a second limit switch 29. The connecting frame 31 is provided with a trigger plate 33 that can trigger the first limit switch 28 and the second limit switch 29.

[0088] Optionally, the first limit switch 28 is located at the upper end of the column 21, and the second limit switch 29 is located at the lower end of the column 21; or, the second limit switch 29 is located at the upper end of the column 21, and the first limit switch 28 is located at the lower end of the column 21. Taking the first limit switch 28 located at the upper end of the column 21 and the second limit switch 29 located at the lower end of the column 21 as an example, when the connecting frame 31 rises, the trigger plate 33 rises accordingly. When the connecting piece rises to the point where the trigger plate 33 triggers the first limit switch 28, the first limit switch 28 can generate a signal, for example, this signal can be sent to the lifting motor to control the lifting motor to shut down, thereby stopping the connecting frame 31 from rising; when the connecting piece descends to the point where the trigger plate 33 triggers the second limit switch 29, the second limit switch 29 can generate a signal, for example, this signal can be sent to the lifting motor to control the lifting motor to shut down, thereby stopping the connecting frame 31 from descending, thus realizing the travel protection of the entire system's lifting.

[0089] In other words, the full-load detection device in this embodiment limits the maximum lifting height and minimum lowering height of the detection device 1 through the first limit switch 28 and the second limit switch 29.

[0090] Preferably, the first limiting stop 26 and the second limiting stop 27 are polyurethane stopping bolts, used to mitigate the impact during a collision.

[0091] Optionally, the first limiting stop 26 is disposed at the upper end of the guide rail 24, and the second limiting stop 27 is disposed at the lower end of the guide rail 24; or, the second limiting stop 27 is disposed at the upper end of the guide rail 24, and the first limiting stop 26 is disposed at the lower end of the guide rail 24. Taking the first limiting stop 26 disposed at the upper end of the guide rail 24 and the second limiting stop 27 disposed at the lower end of the guide rail 24 as an example, the first limiting stop 26 limits the highest limit position of the connecting frame 31, and the second limiting stop 27 limits the lowest limit position of the connecting frame 31, thereby mechanically limiting the maximum lifting height and the minimum lowering height of the detection device 1, ensuring the lifting safety of the detection device 1. For example, when the connecting frame 31 rises and the inertia causes the trigger plate 33 on the connecting frame 31 to rush out of the first limit switch, the first limit stop 26 stops the connecting frame 31 from rising; when the connecting frame 31 falls and the inertia causes the trigger plate 33 on the connecting frame 31 to rush out of the second limit switch, the second limit stop 27 stops the connecting frame 31 from falling, preventing the moving parts from falling off and causing a safety accident, and ensuring safe use.

[0092] Preferably, please refer to Figure 1 In this embodiment, the fully loaded detection equipment also includes a cantilever device, which includes a cantilever beam 4 and a second lifting mechanism installed on the cantilever beam 4. Along the length of the cantilever beam 4, one end of the cantilever beam 4 is connected to the rotating mechanism 3, and the other end is connected to the detection device 1 through the second lifting mechanism. The second lifting mechanism can drive the detection device 1 to rise and fall.

[0093] With this configuration, the rotation of the rotating mechanism 3 can drive the detection device 1 to rotate horizontally via the cantilever beam 4, thus facilitating the detection device 1 to extend a long distance above the carriage. Additionally, the second lifting mechanism can drive the detection device 1 to rise and fall, allowing it to descend and penetrate deep into the carriage to a preset full-load height.

[0094] Preferably, the cantilever beam 4 is made of aluminum profile.

[0095] Preferably, please refer to Figure 4 and Figure 5 In this embodiment, the second lifting mechanism includes a winch 51 mounted on the cantilever beam 4 and a rope 52 connected to the winch 51, with the detection device 1 fixed to the rope 52. This configuration allows the winch 51 to lift or lower the detection device 1 via the rope 52, thus achieving the lifting and lowering of the detection device 1.

[0096] In summary, the full-load detection method implemented using the full-load detection equipment in this embodiment is as follows:

[0097] The fully loaded testing equipment is installed in the loading channel, for example, the column is fixed to the bottom of the loading channel. In addition, in the initial state, the testing device 1 is located in the initial position. Preferably, the initial position of the testing device 1 is that the length direction of the cantilever beam 4 is parallel to the driving direction of the vehicle, so as to reduce the interference of the cantilever beam 4 and the testing device 1 to the driving vehicle.

[0098] Step 1: The vehicle enters the loading channel. The drive unit 22 drives the connecting frame 31 to rise through the transmission assembly. The connecting frame 31 then drives the rotating wheel 12 to rise through the electric rotary table 32, making the height of the rotating wheel higher than the upper edge of the car body. The vehicle continues to drive to the initial loading position and stops. At the same time, the electric rotary table 32 drives the rotating wheel 12 to rotate horizontally above the car body through the cantilever beam 4. The winch 51 lowers the rotating wheel 12 through the rope 52, so that the rotating wheel 12 penetrates into the car body to the preset full load height.

[0099] Step two: Rotating wheel 12 starts to rotate, and at the same time, material begins to fall into the carriage at the position corresponding to the initial loading position, thus forming a material pile in the carriage and increasing the height of the material pile.

[0100] Step 3: When the height of the material pile inside the carriage reaches the rotating wheel 12, it contacts the rotating wheel 12. The loading at this loading position is completed. At this time, the material stops falling at the position corresponding to the initial loading position inside the carriage, and the vehicle stops at the next loading position.

[0101] Step four: Material begins to be unloaded from the corresponding loading position inside the carriage.

[0102] Step 5: Repeat steps 3 and 4 until loading is completed at the rear of the carriage;

[0103] Step six: Drive component 22 drives connecting frame 31 to rise through transmission assembly, thereby connecting frame 31 drives rotating wheel 12 to rise through electric rotary table 32, and winch 51 lifts rotating wheel 12 through rope 52, so that the height of rotating wheel 12 is higher than the height of the upper edge of the car body; electric rotary table 32 drives rotating wheel 12 to rotate horizontally to the initial position through cantilever beam 4, and at the same time the vehicle drives out of the loading channel.

[0104] Preferably, the full-load detection device in this embodiment also includes a control device. The light curtain, the first lifting mechanism 2, the second lifting mechanism, the rotating mechanism 3 and the detection device 1 are all connected to the control device to realize intelligent control of the full-load detection device, thereby automatically realizing the full-load detection method through the full-load detection device.

[0105] The full-load detection device of this embodiment has the advantages of the full-load detection method of Embodiment 1, which has been described in detail in Embodiment 1 and will not be repeated here.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
