Description

Technical Field

[0002] A tire-mounted crane is a specialized engineering vehicle used for transporting and handling heavy tires. It typically employs a powerful boom and support structure, enabling the safe and efficient loading, unloading, and handling of large and heavy engineering tires. Tire-mounted cranes are widely used in mines, construction sites, ports, and other locations, playing a vital role in industrial production and infrastructure construction.

[0003] However, the large size of tire cranes poses certain safety hazards during transportation and handling operations. Due to limited visibility and their large size, drivers have difficulty fully assessing their surroundings, making it easy for tire cranes to deviate from their original tracks during movement, which can even lead to accidents. To address these issues, a magnetic field correction device for tire cranes is proposed. Utility Model Content

A second rotating rod is fixedly connected to the bottom surface of the connecting piece, and a mobile frame is fixedly connected to the bottom end of the second rotating rod. A correction device is provided on the bottom surface of the crane frame, comprising an air cylinder and an air pump, with an air supply pipe fixedly connected between the air cylinder and the air pump.

The second reciprocating swing mechanism is fixedly connected to the first rotating rod. When the moving frame is offset, the piston plate is pushed into the air cylinder by the first reciprocating swing mechanism. The gas is delivered to the cylinder through the gas supply pipe. The output end of the cylinder is extended. The first rotating rod is driven to rotate by the second reciprocating swing mechanism, which drives the moving wheel in the moving frame to reset and correct its deviation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Example 1:

[0028] Please see Figures 1-6 As shown, this utility model is a magnetic field correction device for a tire crane, including a crane frame 1, a moving frame 7, and an industrial control computer. The magnetic field correction device is installed around the periphery of the crane frame 1. The magnetic field correction device includes a magnetic conductor 3, an induction antenna 4, a magnetic field generator 2, and a magnetic field resolver. The magnetic field generator 2 (essentially a high-frequency oscillation circuit) generates a sinusoidal current of a specific frequency (e.g., 20kHz). When the current passes through the magnetic conductor 3 (actually a conductor loop), an alternating magnetic field is formed around the coil according to the Biot-Savart law. The magnetic field distribution is sinusoidal, and the magnetic field strength decreases with distance in a cosine manner. The induction antenna (containing a PCB array of multiple coils) is placed in the magnetic field area. When the crane deviates, the relative position of the antenna coil and the magnetic field changes. According to Faraday's law of electromagnetic induction, the coil cuts the magnetic field lines to generate an induced electromotive force. Coils at different positions output induction signals with different amplitudes due to differences in magnetic field strength. The magnetic field resolver includes an analog front-end and a digital signal processor.

[0029] A / D sampling and FFT spectrum analysis are performed on the multi-channel induction signals. Phase information is extracted using phase-locked loop technology. Noise is eliminated by Kalman filtering. A mathematical model of magnetic field strength-spatial position (such as polynomial fitting or neural network) is established.

[0030] The magnetic field line analyzer is installed inside the industrial control computer. The induction antenna 4 is fixedly installed on one side of the mobile frame 7. Several support seats 8 are laid on the ground by bolts. The upper end of the support seat 8 is fixedly connected to the placement plate 9. The magnetic field line 3 is laid on the upper surface of the placement plate 9. The upper surface of the placement plate 9 is fixedly installed with a fixing component 16. The bottom surface of the fixing component is provided with an arc-shaped groove. The magnetic field line 3 is placed in the arc-shaped groove. The fixing component 16 is fixed to the placement plate 9 by bolts, thereby fixing the magnetic field line 3.

[0031] Working principle:

[0032] Magnetic field line generator 2 generates a sinusoidal signal of a certain frequency and sends it to magnetic field conductor 3. The coil of induction antenna 4 receives the voltage signal through the principle of alternating electric field induction by alternating magnetic field. Since there are multiple coils in induction antenna 4, the strength of the induced signal varies at different positions, thus determining the location of induction antenna 4. The magnetic field line resolver analyzes the strength of multiple signals to determine the position of induction antenna 4, and then performs correction. This correction sensor is applied to the trolley of a tire crane. It obtains the trolley's running deviation signal information through magnetic field line correction and feeds it back to the industrial control computer. Finally, the control system adjusts the speed of the transmission devices on both sides of the trolley to correct the trolley's deviation trend in real time, controlling the deviation of the trolley's travel direction within a certain range. The automatic trolley correction detection system uses magnetic field line correction detection technology to ensure stable trolley travel posture and reliable safety protection.

[0033] Example 2:

[0034] A first rotating rod 5 is rotatably connected to the bottom surface of the crane frame 1. A connecting piece 6 is fixedly connected to the bottom end of the first rotating rod 5. A second rotating rod 15 is fixedly connected to the bottom surface of the connecting piece 6. A movable frame 7 is fixedly connected to the bottom end of the second rotating rod 15. The movable frame 7 is used to control the movement of the tire crane trolley. The movable frame 7 is equipped with movable wheels. The first rotating rod 5 and the second rotating rod 15 are used to control the rotation direction of the movable wheels.

[0035] The bottom surface of the crane frame 1 is equipped with a correction device, which includes an air cylinder 10 and an air cylinder 19. Several mounting brackets 17 are fixedly connected to the bottom surface of the crane frame 1. An annular groove is formed on one surface of the mounting bracket 17. The air cylinder 10 is fixedly installed in the annular groove. An air supply pipe 23 is fixedly connected between the air cylinder 10 and the air cylinder 19. A piston plate 24 and a piston rod 11 are provided inside the air cylinder 10. Both the piston rod 11 and the piston plate 24 are slidably engaged with the air cylinder 10. A movable plate 12 is fixedly connected to one end of the piston rod 11. The movable plate 12 is connected to a first reciprocating swing mechanism. The first reciprocating swing mechanism includes a first connecting rod 13 and a second connecting rod 14. The first connecting rod 13 and the second connecting rod 14 are hinged. Hinged to the movable plate 12, when the movable wheel deviates, the second rotating rod 15 rotates with the movable wheel. The second rotating rod 15, the first connecting rod 13, the second connecting rod 14 and the piston rod 11 constitute a crank-connecting rod mechanism. Therefore, the piston rod 11 and the piston plate 24 will be pushed to move into the air cylinder 10. The air cylinder 10 initially contains a certain amount of gas. The piston plate 24 compresses the gas. A first sealing ring is fixedly connected at the connection position between the gas supply pipe 23 and the cylinder 19, and a second sealing ring is fixedly connected at the connection position between the gas supply pipe 23 and the air cylinder 10 to ensure the airtightness of the gas supply. The gas is delivered to the cylinder 19 through the gas supply pipe 23, so that the output end of the cylinder 19 extends.

[0036] The second connecting rod 14 is fixedly connected to the second rotating rod 15. The output end of the cylinder 19 is fixedly connected to the moving block 20. A one-way valve 18 is fixedly installed on the circumferential side of the air cylinder 10. The function of the one-way valve 18 is to allow air to enter the air cylinder 10 only through the one-way valve and not to exhaust through the one-way valve 18. A second reciprocating swing mechanism is connected to one side of the moving block 20. The second reciprocating swing mechanism includes a third connecting rod 21 and a fourth connecting rod 22. The third connecting rod 21 and the fourth connecting rod 22 are hinged. One end of the fourth connecting rod 22 is fixedly connected to the first rotating rod 5. The third connecting rod 21 is hinged to the moving block 20. The third connecting rod 21, the fourth connecting rod 22, the first rotating rod 5 and the moving block 20 also constitute a crank-connecting rod mechanism. The output end of the cylinder 19 extends and drives the first rotating rod 5 to rotate through the crank-connecting rod mechanism, thereby achieving the function of resetting the moving wheel of the tire crane trolley.

[0037] Working principle:

[0038] When the crane frame 1 lifts and moves the tire, if the moving frame 7 deviates (i.e., the moving frame 7 rotates), the moving frame 7 drives the first rotating rod 5 and the second rotating rod 15 to rotate. The second rotating rod 15, through the connection between the first connecting rod 13 and the second connecting rod 14, pushes the piston rod 11 to move into the air cylinder 10. The piston rod 11 further drives the piston plate 24 to move, causing the piston plate 24 to compress the gas inside the air cylinder 10, and deliver the gas through the air supply pipe 23 to the cylinder 19. The output end of the cylinder 19... Extending outwards, the first rotating rod 5 is pulled to rotate via the third link 21 and the fourth link 22, which in turn pulls the moving wheel to rotate, thus achieving the function of automatic correction. When the first rotating rod 5 rotates, it also drives the second rotating rod 15 to rotate via the connecting piece 6. The second rotating rod 15 further pulls the piston rod 11 to move outwards from the air cylinder 10 via the first link 13 and the second link 14. Gas enters the air cylinder 10 through the one-way valve 18, so that the air cylinder 10 is refilled with gas, which facilitates the next correction function.
