[0032] The present invention provides the following embodiments.
[0033] Example 1
[0034] This invention provides a protective device for a ship unloader, such as... Figure 1 , Figures 7-8 As shown, it includes several anti-tipping devices 14, which are installed at the bottom of the horizontal rotating device 3. The anti-tipping devices 14 are connected to the platform 1 by controlling the second drive motor 1410. The horizontal rotating device 3 travels on the platform 1 via the tracked traveling device 2, and the platform 1 is fixedly connected to the ground.
[0035] Preferably, the anti-tipping device 14 includes an anti-tipping device housing 1404. The mounting platform 1 is provided with a vertical through hole 15 for the lower part of the anti-tipping device housing 1404 to pass through. A plurality of lifting racks 1403 are provided on the upper outer side of the anti-tipping device housing 1404. The lifting racks 1403 mesh with a second gear 1402. The second gear 1402 is fixedly connected to the output shaft of the lifting motor 1401 through a reducer. The lifting motor 1401 is fixed on the bottom surface inside the horizontal rotating device 3. A plurality of upper support pins 1405 and a plurality of lower support pins 1406 are arranged at intervals along the periphery of the anti-tipping device housing 1404. The anti-tipping device housing 1404 is hinged to the upper end of the upper support pins 1405 and the lower end of the lower support pins 1406. Preferably, a second groove is provided on the side of the anti-tipping device housing 1404 at the positions corresponding to the upper support pin 1405 and the lower support pin 1406, and the upper support pin 1405 and the lower support pin 1406 can be inserted into the second groove.
[0036] The anti-tipping device 14 further includes: a second drive motor 1410 and two vertically symmetrical first bevel gears 1413. The second drive motor 1410 is installed at the top of the housing 1404 of the anti-tipping device. The output end of the second drive motor 1410 is fixed to the first bevel gears 1413 through a second support shaft 1411 and a transmission shaft 1412. The two upper and lower first bevel gears 1413 are fixed together by a third support shaft 1415.
[0037] Two sets of symmetrical connection structures are provided, each connected to two first bevel gears 1413. Each connection structure includes several sets of connection components, which are spaced apart along the circumference of the third support shaft 1415. Each connection component includes a second bevel gear 1414, which meshes with one side of the first bevel gear 1413. The second bevel gear 1414 is fixedly connected to one end of a threaded shaft 1416, and the other end of the threaded shaft 1416 is connected to the anti-tipping device housing 1404 via a bearing seat 1419. The threaded shaft 1416 is helically connected to a threaded transfer plate 1417, and the outer surface of the threaded transfer plate 1417 is rigidly connected to one end of an L-shaped moving rod 1418. The other end of the upper L-shaped moving rod 1418 is movably hinged to the inner side of the upper support pin 1405, and the other end of the lower L-shaped moving rod 1418 is movably hinged to the inner side of the lower support pin 1406.
[0038] The thrust bearing 1408 is installed at the bottom of the anti-tipping device housing 1404 via a support column 1409; the end of the support column 1409 away from the thrust bearing 1408 is connected to the first bevel gear 1413 below via a key; the thrust bearing 1408 is reinforced and fixed to the inner wall of the anti-tipping device housing 1404 via a third fixing strip 1407.
[0039] The working principle and beneficial effects of the above technical solution are as follows:
[0040] 1. The anti-tipping device 14 effectively improves the stability and safety of the ship unloader. The anti-tipping device 14 is located at the bottom of the horizontal rotating device 3 and can be fixed to the platform 1 by controlling the second drive motor 1410, which helps to prevent the ship unloader from tipping over during operation;
[0041] 2. The anti-tipping device housing 1404 is hinged to the upper support pin 1405 and the lower support pin 1406. When the anti-tipping device 14 is at rest, the upper support pin 1405 and the lower support pin 1406 are embedded in the second groove on the anti-tipping device housing 1404. When the ship unloader is working, the second drive motor 1410 drives the first bevel gear 1413 and the second bevel gear 1414, causing the threaded shaft 1416 to rotate and the threaded transfer plate 1417 and the L-shaped moving rod 1418 to move horizontally, thereby pushing out the upper support pin 1405 and the lower support pin 1406, so that the anti-tipping device 14 is stuck in the middle of the mounting platform 1, thereby enhancing the structural stability of the ship unloader and effectively preventing the ship unloader from tipping over.
[0042] 3. By controlling devices such as the lifting motor 1401, precise control of the anti-tipping device 14 can be achieved, thereby driving the anti-tipping device 14 to extend when the unloader moves to the loading platform 1. This helps to adjust the working state of the device when needed, ensuring that the anti-tipping device 14 does not affect the movement of the unloader.
[0043] 4. The anti-tipping device 14 incorporates transmission and connection structures, such as the lifting rack 1403, the first bevel gear 1413, and the second bevel gear 1414. This structural innovation enables the anti-tipping device to work collaboratively in multiple ways. When the anti-tipping device 14 extends, the upper support pin 1405 and the lower support pin 1406 are pushed out, saving motion control time and achieving a highly efficient anti-tipping function.
[0044] In summary, by introducing the anti-tipping device 14, the ship unloader protection device further enhances the stability and safety of the ship unloader, and provides benefits such as multiple protections, precise control, and structural innovation, ensuring the reliability and stability of the ship unloader during operation.
[0045] The present invention solves the following problems mentioned in the background art: existing ship unloaders (such as CN210393006U) usually have the following problems: ship unloaders need to work in complex and changeable environments, are prone to overturning, and lack devices to prevent ship unloaders from overturning.
[0046] Example 2, based on Example 1, such as Figure 1-6As shown, it also includes a protective material handling device 13. The second robotic arm 12 is connected to the rotating end of the horizontal rotating device 3 via a connecting device. The protective material handling device 13 includes a dustproof shell 1302, which is connected to the working end of the second robotic arm 12. The dustproof shell 1302 is wider at the top and narrower at the bottom. The inner side of the wider section of the dustproof shell 1302 is fixed to the drive motor housing 1314 by several first fixing strips 1315. The drive motor is placed inside the drive motor housing 1314, and the output end of the drive motor passes through the drive motor housing 1314 and... A coupling is fixedly connected to a screw 1316; a spiral transport strip 1317 is spirally wound and rigidly connected to the screw 1316; the screw 1316 is fixed to a cleaning rod 1334 near the drive motor housing 1314 by a second fixing strip 1335; the cleaning rod 1334 is completely fitted to the inner side of the dustproof shell 1302; preferably, the protective material handling device 13 includes a threaded section 1301, which is threadedly connected to the working end of the second robotic arm 12, and the other end of the threaded section 1301 is rigidly connected to the dustproof shell 1302;
[0047] Preferably, the protective material handling device 13 further includes:
[0048] A fixing ring 1303 is connected to the upper part of the dustproof shell 1302; a plurality of first protective strips 1308 are arranged at intervals along the periphery of the fixing ring 1303, and the first protective strips 1308 slide through the limiting ring provided on the fixing ring 1303; a rack segment is provided on the upper end of the first protective strip 1308 near the dustproof shell 1302, and the rack segment meshes with a first gear 1307; the first gear 1307 is connected to the output end of a first drive motor 1306 through a reducer; the first drive motor 1306 is fixed on the fixing ring 1303.
[0049] The lower end of the first protective strip 1308 is rigidly connected to the second protective strip 1309; a second hinge seat is installed on the side of the second protective strip 1309 away from the dustproof shell 1302, and one end of the second connecting rod 1312 is hinged to the second protective strip 1309 through the second hinge seat; the other end of the second connecting rod 1312 is hinged to one end of the third connecting rod 1313; the other end of the third connecting rod 1313 is hinged to the third hinge seat provided on the third protective strip 1310; the upper end of the third protective strip 1310 is hinged to the end of the second protective strip 1309 away from the first protective strip 1308.
[0050] The working principle and beneficial effects of the above technical solution are as follows: 1. The protective material handling device 13 can effectively transfer materials to the unloader, making the unloader's operation more efficient and automated. At the same time, the cleaning rod 1334 and dustproof shell 1302 inside the device help keep the device clean and reduce the accumulation and contamination of materials (mainly coal);
[0051] 2. The dust cover 1302 can prevent materials (mainly coal) from scattering during the transfer process, thereby reducing environmental pollution; the configuration of the first protective strip 1308, the second protective strip 1309, and the third protective strip 1310 can drive the protective material handling device 13 to protect it when it is close to an obstacle, effectively protecting the normal operation of the equipment and extending the service life of the equipment.
[0052] 3. The use of the first drive motor 1306 and related gear rack device enables the third protective strip 1310 to achieve automatic up and down lifting motion control. When protection is needed, the third protective strip 1310 can be lowered in time for protection. This automatic motion control improves the convenience and stability of the protection operation.
[0053] 4. Through the reasonable combination of components such as screw 1316 and spiral conveyor 1317, the complex movement and control of the device are realized, so that the protective material handling device 13 can efficiently absorb the material to be transported (mainly coal).
[0054] In summary, the protective material handling device 13 of Embodiment 1 has significant beneficial effects in terms of automation, dust prevention, protection, automatic control, structural innovation and vibration reduction design, which can improve the working efficiency of the ship unloader and the reliability of the equipment.
[0055] The present invention solves the following problems mentioned in the background art: existing ship unloaders (such as CN210393006U) usually have the following problems: the material handling device does not have a protective function and the function of the material handling device is easily affected by collision.
[0056] Example 3, based on Example 2, such as Figures 1-6As shown, a shock-absorbing disc 1322 is installed at the end of the third protective strip 1310. The shock-absorbing disc 1322 includes a support disc 1323, which is fixedly connected to the third protective strip 1310 via a fixing post. The support disc 1323 has several first grooves, the bottom of which is fixedly connected to a first spring 1327. The other end of the first spring 1327 is fixedly connected to a first limiting disc 1326. The first limiting disc 1326 is rigidly connected to a first support shaft 1325, which passes through the first limiting disc 1326 and extends into the first spring 1327. The other end of the first support shaft 1325 is connected to a shock-absorbing arc surface. 1324 is rigidly connected; the periphery of the first support shaft 1325 is hinged to one end of several fourth connecting rods 1329 via several fourth hinge seats; the other end of the fourth connecting rod 1329 is hinged to a first hinge seat 1330; the bottom surface of the first hinge seat 1330 is rigidly connected to a second limiting disc 1331; the second limiting disc 1331 is slidably connected to a sliding groove provided on the inner side of the shock-absorbing base 1333; the shock-absorbing base 1333 is fixed on a side plate 1328, and the side plate 1328 is fixed on the surface of the support disc 1323; a second spring 1332 is installed inside the shock-absorbing base 1333, and the second spring 1332 is fixed to the second limiting disc 1331 and the shock-absorbing base 1333 respectively.
[0057] The beneficial effects of the above technical solution are as follows: 1. The dustproof shell 1302 can prevent materials (mainly coal) from scattering during the transfer process, thereby reducing environmental pollution; the configuration of the first protective strip 1308, the second protective strip 1309, the third protective strip 1310 and the shock-absorbing disc 1322 can drive the protective material handling device 13 to protect it when it is close to an obstacle, effectively protecting the normal operation of the equipment and extending the service life of the equipment;
[0058] 2. The damping devices such as the first spring 1327 and the second spring 1332 in the damping disc 1322 can effectively reduce vibration and impact, protect the device and equipment from external forces, ensure the stability and safety of the device, and reduce the risk of accidents.
[0059] Example 4, based on Example 2 or 3, such as Figure 2 and Figure 4As shown, it also includes: a pneumatic cylinder 1318; the first protective strip 1308 is a shell structure; the pneumatic cylinder 1318 is installed inside the upper end of the first protective strip 1308; the bottom end of the pneumatic cylinder 1318 is connected to the first pneumatic push rod 1319; the second pneumatic push rod 1320 is installed inside the first pneumatic push rod 1319; the first pneumatic push rod 1319 and the second pneumatic push rod 1320 are slidably connected; a shock-absorbing spring 1321 is sleeved on the second pneumatic push rod 1320; one end of the shock-absorbing spring 1321 is fixed to a limiting ring provided on the second pneumatic push rod 1320; the other end of the shock-absorbing spring 1321 is fixed to the bottom end of the first pneumatic push rod 1319; the bottom end of the second pneumatic push rod 1320 is hinged to one end of the first connecting rod 1311; the other end of the first connecting rod 1311 is movably hinged to the hinge joint of the second connecting rod 1312 and the third connecting rod 1313.
[0060] The working distance and beneficial effects of the above technical solution are as follows: 1. The use of devices such as pneumatic cylinder 1318, protective strip and connecting rod enables the third protective strip 1310 to realize automatic swing motion control, and can drive the third protective strip 1310 to approach the dust cover 1302 suction port in time when protection is needed, so as to provide more comprehensive protection.
[0061] 2. The introduction of shock-absorbing spring 1321 helps to reduce or suppress vibrations and impacts generated during loading and unloading, thereby improving the stability and smooth operation of the device;
[0062] 3.

The control room 4 and a horizontal rotating device 3 are mounted on top of the tracked traveling device 2. A vertical transport device 5 is mounted on top of the horizontal rotating device 3 for transporting materials.

[0068] 2.

[0071] Example 6
[0072] Based on Example 5, an anti-rollover control system is also included, which includes:
[0073] Wind speed sensor, which is installed on the top of fixed column 7, is used to detect wind speed;
[0074] A distance sensor is installed on the horizontal telescopic device 9 to detect the extension distance (extension through slot) of the center of gravity of the horizontal transport device 10.
[0075] Automatic controller, which is installed in control room 4;
[0076] First, the automatic controller calculates the overturning torque of the unloader based on the wind speed information detected by the wind speed sensor. Then, the automatic controller calculates the overturning torque of the unloader itself based on the displacement of the end of the horizontal conveyor 10 detected by the distance sensor and the material density. Finally, the automatic controller comprehensively determines whether to control the anti-tipping device 14 to operate based on the obtained overturning torques. The specific control process is as follows:
[0077] Step 1: The automatic controller calculates the overturning torque M1 of the unloader based on the wind speed information v detected in real time by the wind speed sensor.
[0078]
[0079] Where: M1 is the overturning torque of the unloader caused by the wind, η is the wind force coefficient (1≤η≤2), S is the windward area of the unloader, l is the vertical distance from the center of mass of the unloader to the ground, ρ0 is the air density, v is the wind speed detected by the wind speed sensor, ε is the difference coefficient between the maximum windward area of the unloader and the windward area of the vertical transport device 5 as determined by the experiment (0<ε<1), R is the bottom radius of the vertical transport device 5, h0 is the height of the vertical transport device 5; P is the ambient wind pressure.
[0080] Step 2: Based on the horizontal displacement x1 of the end of the horizontal conveying device 10 (the end closest to the material handling device) relative to the center of mass of the unloader, detected by the distance sensor, and the material density, the automatic controller calculates the overturning torque M2 of the unloader itself.
[0081]
[0082] Where: M2 is the overturning torque of the unloader itself on the unloader; G1, G2, G3, and G4 are the weights of the horizontal transport device 10 and its internal conveying pipes, the first robotic arm 11 and its internal conveying pipes, the second robotic arm 12 and its internal conveying pipes, and the protective material handling device 13 and its internal conveying pipes, respectively; ρ is the density of the material (e.g., coal); r1, r2, r3, and r4 are the inner diameters of the conveying pipes in the horizontal transport device 10, the first robotic arm 11, the second robotic arm 12, and the protective material handling device 13, respectively; l1, l2, l3, and l4 are the lengths of the conveying pipes in the horizontal transport device 10, the first robotic arm 11, the second robotic arm 12, and the protective material handling device 13, respectively; g is the acceleration due to gravity; α1, α2, α3, and α4 are the position coefficients of the center of mass of the horizontal transport device 10, the first robotic arm 11, the second robotic arm 12, and the protective material handling device 13 relative to their lengths (0 ≤ α). j <1), θ1, θ2, θ3, and θ4 are the deflection angles of the horizontal transport device 10, the first robotic arm 11, the second robotic arm 12, and the protective material handling device 13 relative to the vertical plane (specifically, θ1 = -90°); π is 3.14; sin is sine;
[0083] Step 3: The automatic controller obtains the comprehensive judgment coefficient σ based on the calculated M1 and M2:
[0084] M3=G(l1-x1)+G′y (3)
[0085] σ=max{M3-(M2+M1cosθ)ln(1+β),G′y-M1 sinθ}-M δ (4)
[0086] Where: M3 is the torque of the main parts of the ship unloader on the ship unloader itself, G is the weight of the limit box 6, G′ is the total weight of the track travel device 2, the horizontal rotation device 3 and the vertical transport device 5, y is the height of the ship unloader's center of gravity above the ground, σ is the comprehensive judgment coefficient, θ is the angle between the wind direction detected by the wind speed sensor and the vertical plane, β is the experimentally determined warning coefficient (greater than 1), M δ The safety torque (greater than 0) is set according to the operating conditions; cos is the cosine.
[0087] Step 4: The automatic controller determines whether to activate the anti-rollover device 14 based on the magnitude of the comprehensive judgment coefficient σ. If σ is greater than 0, the anti-rollover device 14 is activated.
[0088] The beneficial effects of the above technical solution are as follows:
[0089] 1. Wind speed and distance sensors were introduced to monitor environmental factors (such as wind speed) and equipment status (such as the extension distance of the horizontal transport device) in real time, and to calculate the overturning torque of the unloader caused by the wind and the overturning torque of the unloader itself. By comparing the comprehensive judgment coefficient σ, automatic anti-tipping control of the unloader was achieved, greatly improving the safety of the unloader;
[0090] 2. The anti-tipping control system automates the calculation and judgment process through an automatic controller. It performs complex calculations based on real-time sensor data and preset parameters, and intelligently controls the operation of the anti-tipping device 14 based on the calculation results. This intelligent control method improves the operating efficiency and accuracy of the unloader.
[0091] 3. The calculation and judgment process of the anti-tipping control system considers various factors, such as wind speed, center of gravity position, and material density, enabling the ship unloader to make appropriate anti-tipping control decisions under different operating conditions. Simultaneously, a safety torque M, set according to the operating conditions, is introduced. δ This provides sufficient time for driving the anti-tipping device 14, enhancing the device's adaptability and stability in various environments.
[0092] 4. The introduction of an automatic controller and a precise calculation mechanism reduces the degree of human intervention. The system can autonomously determine whether the anti-tipping device 14 needs to be activated, thereby reducing the workload of the operator and reducing the risk of human error.
[0093] In summary, the anti-tipping control system of this ship unloader protection device achieves intelligent and highly adaptable anti-tipping control through the coordinated action of wind speed sensors, distance sensors, and automatic controllers, thereby improving the safety and operational efficiency of the ship unloader.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
