Abstract
Description
Technical Field
[0001] The present application relates to the technical field of coking dry quenching equipment, and in particular to a small anti-eccentric loading device. Background Art
[0002] In the CDQ red coke loading system, the electric locomotive is responsible for pulling the coke tank trolley to receive and transport the coke. After the coke tank trolley receives the coke, it is pulled to the bottom of the CDQ furnace lifting derrick and accurately positioned by the APS positioning clamping device to ensure the safety and accuracy of the coke tank during the lifting process.
[0003] The APS device consists of a hydraulic station and hydraulic cylinders, and is fixed to the ground directly below the elevator. The manipulators on both sides can clamp the main structure of the alignment device on the coke tank trolley, thereby fixing the position of the coke tank trolley and aligning the coke tank's hanging ear axis with the center point of the elevator's hook precisely to achieve smooth lifting.
[0004] It was originally planned that the 1# electric locomotive would deliver coke cans to the 1# CDQ and the 2# electric locomotive would deliver coke cans to the 2# CDQ. The two systems would be used separately. Now, according to actual production needs, the 2# electric locomotive needs to deliver coke cans to the 1# CDQ and the 2# CDQ alternately. However, due to the influence of external factors such as on-site construction errors, after the APS clamped the on-board alignment device of the 2# electric locomotive, there was a deviation in the alignment between the coke can lifting lug beam and the center point of the 1# CDQ hoist hook. Figure 1 As shown in the figure, this deviation will cause uneven force on the hoist rope during the lifting process, causing the coke tank to tilt, thereby triggering the system overload alarm and causing production interruption.
[0005] In the related art, in order to solve this problem, the relative positions of the APS device and the electric locomotive alignment device are adjusted. This method consumes a lot of manpower and material resources, is not only time-consuming and labor-intensive, but also costly and difficult to implement, so it needs to be improved. Utility Model Content

The double-acting cylinder 32 is equipped with a base 6, and the base 6 is installed on the coke tank trolley 1. In this embodiment, the base 6 includes four iron plates 61, and the four iron plates 61 are respectively installed at the corners of the double-acting cylinder 32. Each iron plate 61 is installed with four-corner bolts 62 for fixing; the base 6 provides a stable installation platform for the double-acting cylinder 32, ensuring the stability and reliability of the cylinder on the coke tank trolley 1.
[0037] Reference Figure 3 and Figure 4 The double-acting cylinder 32 has a piston rod 4, a correction slider 31 is connected to the end of the piston rod 4, and the correction slider 31 is slidably connected to the right iron block 23. The width of the correction slider 31 is twice the offset of the hoist hook 14. In this embodiment, the center position of the coke tank lifting ear beam is measured to be offset to the right by 1.5 cm relative to the hook, and the offset is △X=1.5 cm.

[0038] Reference Figure 3 and Figure 4 An open groove 7 is provided on the correcting slider 31, and the piston rod 4 of the double-acting cylinder 32 is inserted and fixed in the open groove 7. A positioning hole 8 is provided on the side wall of the correcting slider 31, and the inner wall of the positioning hole 8 is connected to the inner wall of the open groove 7.

[0039] Reference Figure 3 and Figure 4A magnetic ring 11 is installed on the piston rod 4 of the double-acting cylinder 32, and two sensors 12 are installed on the cylinder body of the double-acting cylinder 32.

[0040] Reference Figure 3 A two-position five-way solenoid valve 5 is installed on the coke tank trolley 1. The two-position five-way solenoid valve 5 is actually installed in the control box on the coke tank trolley 1 to control the double-acting cylinder 32. The energization status of the coil of the two-position five-way solenoid valve 5 is interlocked with the running signal of the electric locomotive. When the electric locomotive transports the coke tank to the 1# dry quenching coke tank, the positive action coil is energized and the correction slider 31 moves down. When the electric locomotive transports the coke tank to the 2# dry quenching coke tank, the reverse action coil is energized and the correction slider 31 moves up. At the same time, a double-electrically controlled two-position five-way solenoid valve 5 is selected. When the positive action coil is energized, the positive action gas circuit is connected. Even after the power is off, the positive action gas circuit is still connected and will be maintained until the reverse action coil is energized, and vice versa, which is equivalent to "self-locking".
[0041] The implementation principle of a small anti-eccentric load device in the embodiment of the present application is as follows: when the electric locomotive transports the coke can to the 1# dry quenching coke, the coke can after the 1# dry quenching coke lifting mechanism large hook and the APS clamping alignment cannot be accurately aligned. The measured center position of the coke can lifting ear beam is offset to the right relative to the hook. In order to eliminate the influence of the offset △X, a correction slider 31 with a width of △Y=2△X is added to the right side of the alignment body. The positive action coil of the solenoid valve is energized, and the double-acting cylinder 32 pushes the correction slider 31 down to the lower limit and then stops moving. The ground APS device Clamp, then the coke tank trolley 1 and the coke tank fixed thereon will move a distance to the left relative to the original position (without the slider), and the coke tank lifting ear beam and the center point of the 1# dry quenching coke hoist hook are on the same vertical line, which is equivalent to eliminating the offset △X, and the 1# dry quenching coke lifting mechanism and the coke tank to be lifted can be accurately aligned to achieve the purpose of preventing eccentric loading during the coke tank lifting process after alignment. At the same time, when the electric locomotive transports the coke tank to the 2# dry quenching coke, since the 2# dry quenching coke has no offset in alignment, it is sufficient to lift the correction slider 31;
[0042] By setting the correcting slider 31, the double-acting cylinder 32 and the two-position five-way solenoid valve 5, the anti-eccentric load requirements of two or even more electric locomotive alignment systems can be met. The installation position of the correcting slider 31 and the thickness of the slider can be flexibly selected according to the actual needs on site, thereby improving its scope of application and practicality. Compared with traditional methods, the device does not require a large amount of manpower and material resources to complete the alignment adjustment work, which not only saves human resource costs, but also reduces material consumption and equipment wear costs caused by frequent adjustments, achieves precise alignment and rapid response capabilities, significantly improves the utilization rate and work efficiency of electric locomotives and coke drums, reduces unit costs and improves overall economic benefits.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
