Description

Technical Field

[0001] This utility model belongs to the field of technology for dumping intermediate process products or slag generated during the smelting of non-ferrous metals, and particularly relates to a mobile bag-turning device. Background Technology

[0002] In the non-ferrous metal smelting industry, intermediate products or slag generated from high-temperature smelting must be received in slag ladles and cooled by spraying in an open-air slow-cooling area before being dumped. Currently, the industry generally relies on gantry cranes to complete the hoisting and turning of slag ladles. This involves using a main hook to lift the slag ladle to the dumping area, and then using a secondary hook to retrieve the bottom hook of the slag ladle. The main and secondary hooks work together to turn the slag ladle. This technology has significant drawbacks: First, the operation of the secondary hook on the bottom hook is cumbersome and poses safety risks, requiring highly skilled operators. Second, due to structural limitations, the maximum turning angle is only about 130 degrees, resulting in incomplete emptying of the slag ladle and time-consuming and labor-intensive subsequent cleaning. Third, during the turning process, the large slag ladle is prone to bouncing, and the resulting enormous inertial force can cause the gantry crane's moving trolley to derail, posing a serious safety hazard. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a mobile bag-turning device, which solves the problems of poor safety and incomplete dumping of residue by horizontal rotation and 180-degree flipping.

[0004] Technical solution: To achieve the above objectives, this utility model provides a mobile bag-flipping device, comprising:

[0005] Mobile carrier;

[0006] A rotating carrier mounted on the moving carrier via a rotating mechanism;

[0007] The slag bag holder is mounted on the rotating carrier via a flipping mechanism;

[0008] And a slag bag locking mechanism disposed on the slag bag holder;

[0009] The rotating mechanism can drive the rotating carrier to rotate the slag bag seat horizontally to the slag dumping station side; the flipping mechanism can drive the slag bag fixed by the slag bag locking mechanism to flip more than 90 degrees.

[0010] Furthermore, the tilting mechanism drives the slag bag holder to tilt at an angle of 180 degrees.

[0011] Furthermore, it also includes a vibration cleaning mechanism, which is mounted on a rotating carrier or slag bag seat and is used to apply vibration to the slag bag when the slag bag is flipped to the slag dumping station.

[0012] Furthermore, the vibration cleaning mechanism includes a vibration actuator and an adjustment mechanism for adjusting the operating angle of the vibration actuator.

[0013] Furthermore, the mobile carrier is a rail vehicle or a wheeled vehicle.

[0014] Furthermore, it also includes a safety anchor for locking the mobile carrier to the track or the ground during bag-turning operations.

[0015] Furthermore, the slag bag locking mechanism includes a positioning hook hinged or axially connected to the slag bag seat and a positioning hook driving device for driving the positioning hook to rotate.

[0016] The positioning hook drive device can drive the positioning hook to rotate until the hook body is engaged with or disengaged from the trunnion of the slag bag.

[0017] Furthermore, the rotating mechanism includes a slewing bearing and a rotary drive device.

[0018] Furthermore, the flipping mechanism includes a flipping drive device and a transmission connecting seat; the slag bag seat is mounted on the rotating carrier via a flipping shaft; the flipping drive device is connected to the flipping shaft via the transmission connecting seat.

[0019] Beneficial effects: This utility model improves operational safety by adopting a process of first rotating horizontally to the slag dumping station side and then flipping and dumping; at the same time, the maximum flipping angle of 180 degrees ensures that the slag bag opening is completely facing downwards, providing the optimal path for the complete removal of slag under gravity, fundamentally solving the problem of incomplete slag dumping caused by insufficient flipping angle in the original technology.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, a mobile bag-turning device includes: a mobile carrier 1; a rotating carrier 3 disposed on the mobile carrier 1 via a rotating mechanism 2; a slag bag seat 5 disposed on the rotating carrier 3 via a flipping mechanism 4; and a slag bag locking mechanism 9 disposed on the slag bag seat 5.

[0026] The rotating mechanism 2 drives the rotating carrier 3 to rotate the slag bag seat 5 horizontally to the slag dumping station side. Subsequently, the flipping mechanism 4 drives the slag bag 6, fixed by the slag bag locking mechanism 9, to flip more than 90 degrees. Once the center of gravity of the slag bag 6 has deviated from the load-bearing base, the flipping mechanism 4 provides power to push the slag bag seat 5 and the slag bag 6 to flip around a horizontal axis. The flipping angle is greater than 90 degrees, ensuring that the material inside the slag bag 6 can obtain a better sliding path under gravity, fundamentally solving the problem of incomplete emptying caused by small-angle flipping.

[0027] The flipping mechanism 4 drives the slag bag seat 5 to flip 180 degrees. The flipping mechanism 4 (such as a motor) provides sufficient stroke and torque to continuously push the slag bag 6 from a horizontal position to an inverted position. When the flipping reaches 180 degrees, the slag bag opening is completely vertically downward, which causes the material to lose any horizontal support surface to adhere to under the action of gravity. This provides ideal conditions for the complete and automatic emptying of all loose material in the slag bag 6 under gravity, and is the most effective measure to achieve thorough slag removal.

[0028] This invention also includes a vibration cleaning mechanism, which is mounted on the rotating carrier 3 or the slag bag seat 5, and is used to apply vibration to the slag bag 6 when it is flipped to the slag dumping position. More specifically, the vibration cleaning mechanism includes a vibration actuator 7 and an adjustment mechanism 8 for adjusting the angle of the vibration actuator. When the slag bag 6 is flipped to the slag dumping position (especially at 180 degrees), the high-frequency impact force generated by the vibration actuator 7 (such as a hydraulic vibratory hammer) is directly transmitted to the slag bag body. This impact force can effectively overcome the adhesion force and static friction between viscous or slightly sintered residue and the inner wall of the slag bag. For adhesive residue that cannot be removed by gravity alone, mechanical vibration can loosen, peel off and fall it, which is a powerful supplement to gravity dumping and further ensures the thoroughness of slag cleaning.

[0029] The adjustment mechanism 8 (such as a set of articulated arms and a drive cylinder) can change the extension angle and contact position of the vibratory actuator 7, so that a vibration source can adapt to slag bags of different sizes and can accurately target the bottom or side wall of the slag bag for vibration, which greatly improves the efficiency and adaptability of vibration cleaning.

[0030] The mobile carrier 1 is a rail vehicle or a wheeled vehicle. Integrating the entire bag-turning device into a mobile platform improves flexibility. Rail vehicles are suitable for continuous operations in fixed areas, while wheeled vehicles (such as heavy-duty truck chassis) are suitable for working conditions that require flexible transfer between different cooling areas or work points, thus expanding the application range of the equipment.

[0031] This utility model also includes a safety anchor 10 for locking the mobile carrier 1 to the track or ground during the overturning operation. Before the rotation and overturning action begins, the anchor pin or jaws are forcibly pressed against the track or inserted into the ground by hydraulic or mechanical drive, rigidly connecting the entire equipment to the earth or a solid track. This is to resist and balance the huge overturning moment generated by off-center rotation and large-angle overturning, which is a key safety guarantee to ensure absolute stability throughout the operation and prevent the equipment from shaking or overturning.

[0032] In another preferred embodiment, if the mobile carrier 1 is a rail vehicle, the safety anchor 10 is preferably a rail grabber.

[0033] It should be clarified that the slag bag 6 itself has supporting feet at the bottom and trunnions on the sides. The slag bag base 5 has a basin-shaped base structure. When the slag bag 6 is hoisted into the slag bag base 5, it is supported by the supporting feet to ensure initial stability.

[0034] The slag bag locking mechanism 9 includes a positioning hook 91 hinged or axially connected to the slag bag seat 5 and a positioning hook drive device 92 that drives the positioning hook 91 to rotate. The positioning hook drive device 92 can drive the positioning hook 91 to rotate until the hook body engages or disengages from the trunnion of the slag bag 6. In the initial state, the slag bag seat 5 supports the slag bag 6 from the bottom. When the positioning hook 91 rotates under the action of the drive device 92 and engages the trunnion, a joint fixation is formed on the slag bag 6, at which point the slag bag 6 and the slag bag seat 5 constitute a fixed whole. When the rotation angle is less than 90 degrees, the weight of the slag bag is mainly borne by the slag bag seat 5; when the rotation angle exceeds 90 degrees up to 180 degrees, the weight of the slag bag is entirely borne by the supporting force of the two positioning hooks 91 on the trunnion. This design ensures that the slag bag 6 is reliably locked throughout the entire rotation range from 0 to 180 degrees, with no risk of falling off. The positioning hook drive device 92 is preferably a hydraulic cylinder.

[0035] The rotating mechanism includes a slewing bearing 21 and a rotary drive device. The slewing bearing 21 is a large bearing capable of simultaneously withstanding axial force, radial force, and overturning moment, providing a foundation for the smooth rotation of the rotating carrier 3. The rotary drive device (such as a motor reducer driving a pinion) meshes with the external or internal gear ring of the slewing bearing 21, providing rotational power and enabling the rotating carrier 3 to achieve smooth and precise 90-degree horizontal rotation when carrying a load. It has a compact structure and strong load-bearing capacity.

[0036] The flipping mechanism 4 includes a flipping drive device and a transmission connecting seat 41; the slag bag seat 5 is mounted on the rotating carrier 3 via a flipping shaft; the flipping drive device is connected to the flipping shaft via the transmission connecting seat 41. In a preferred embodiment, the flipping drive device may be a flipping motor.

[0037] The rotating carrier 3 is also equipped with a hydraulic station 11, an electrical control box 12, and a counterweight 13.

[0038] This utility model also has the following advantages:

[0039] 1) Adopting a work process of first rotating horizontally to the slag dumping station side, and then tilting and dumping, improves work safety.

[0040] 2) The maximum flipping angle of 180 degrees ensures that the slag bag opening is completely downward, providing the optimal path for the complete removal of slag under gravity, fundamentally solving the problem of incomplete slag dumping caused by insufficient flipping angle in the original technology.

[0041] 3) Integrating complex bag-flipping operations onto a mobile carrier simplifies the operation process, reduces reliance on specific large-scale lifting equipment and operator skills, and significantly improves the reliability, thoroughness, and overall efficiency of the operation.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
