Description

Technical Field

[0001] This utility model relates to the field of unblocking technology, specifically a novel unblocking device for online material handling. Background Technology

[0002] In heavy industrial production settings such as large cement plants and steel mills, the continuous and stable transportation of raw materials (such as cement meal, slag, and pulverized coal) is a crucial link in ensuring smooth production processes. When these materials are transferred through discharge ports and chutes, they are prone to blockages at the discharge port due to factors such as fluctuating moisture content (most prone to caking at 3%-15% moisture content), high viscosity (such as mineral powder containing clay), or uneven particle size distribution. If these "minor incidents" are not handled promptly, they can trigger a chain reaction: at best, they can lead to material imbalances, causing subsequent products (such as cement clinker and steel billets) to be batch-conforming due to compositional deviations. According to statistics from a cement plant, such quality incidents account for 28% of the total defect rate. At worst, they can completely paralyze the feeding system, forcing the production line to shut down for cleaning, with single downtime losses reaching tens to hundreds of thousands of yuan.

[0003] Traditional cleaning relies on manual labor using tools such as hammers, steel pipes, and crowbars to knock and pry open blocked areas. This requires 2-3 people working together, and a single cleaning session typically takes more than 30 minutes, severely impacting production continuity. Furthermore, during manual cleaning, workers must be in close proximity to high-speed feeding equipment or positioned below elevated chutes, where flying material fragments or sudden collapses can easily cause injuries such as crushing or crushing. Additionally, prolonged use of heavy tools can lead to occupational diseases such as lumbar muscle strain and joint damage. Utility Model Content

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0042] This utility model provides, for example Figure 1-3 The novel online material handling and unblocking device shown includes: a telescopic device 1; an hydraulic control device 2, which controls the telescopic movement of the telescopic device 1; and a pushing device 3, connected to the end of the telescopic device 1, used for unblocking materials. The hydraulic control device 2 controls the telescopic movement of the telescopic device 1, causing the hydraulic cylinder 12 to extend and push the pushing device 3 in a linear motion. This pushes the accumulated material through the unblocking plate 32, thus unblocking the material without requiring close-range manual operation. Compared to the traditional manual unblocking process that takes more than 30 minutes, this device significantly improves the efficiency of unblocking per operation. After installing the fixed bracket 11 inside the equipment, remote control can be achieved through the cooperation between the telescopic device 1 and the hydraulic control device 2. Workers do not need to be in close contact with high-speed operating equipment or in areas at risk of material collapse, fundamentally avoiding accidents such as material splashing and crushing during manual knocking. Simultaneously, it replaces manual heavy-duty work, reducing the occurrence of occupational diseases such as lumbar muscle strain and joint injuries.

[0043] The telescopic device 1 includes: a fixed bracket 11; and a hydraulic cylinder 12. The hydraulic cylinder 12 is fixedly installed on the fixed bracket 11. The fixed bracket 11 is assembled into the equipment that needs to be cleared through an external installation structure, thereby realizing the installation of the clearing device. The telescopic movement of the hydraulic cylinder 12 can drive the pushing device 3 to move linearly, so that the pushing device 3 is pushed in the direction of the blockage, thus facilitating the clearing of the material.

[0044] The hydraulic control device 2 includes: an oil pump 21, which is located on one side of the telescopic device 1; a return oil pipe 22 and an inlet oil pipe 23, which connect the hydraulic cylinder 12 and the oil pump 21. Through the cooperation between the return oil pipe 22 and the inlet oil pipe 23, the flow of oil inside the hydraulic cylinder 12 is controlled. The oil pump 21, as a power source, generates pressurized oil through a motor drive, providing power to the entire hydraulic system. Its core function is to convert mechanical energy into hydraulic energy, pressurizing the oil to give it the pressure to drive the actuator, thereby controlling the telescopic movement of the hydraulic cylinder 12 and providing pushing power to the cleaning plate 32. The output pressure of the oil pump 21 can be adjusted according to the degree of material blockage, ensuring that the thrust is controllable during the clearing process. The inlet oil pipe 23 is a high-pressure oil channel connecting the hydraulic cylinder 12. When the oil pump 21 operates, high-pressure oil is delivered to the hydraulic cylinder 12 through the inlet pipe 23, pushing the piston to move along the cylinder barrel, thus extending the hydraulic cylinder 12. This, in turn, drives the cleaning plate 32 of the pushing device 3 forward, applying thrust to the blockage material to clear the blockage. The return pipe 22 serves as a low-pressure oil return channel, connecting the other chamber of the hydraulic cylinder 12 to the oil tank. When the hydraulic cylinder 12 needs to retract, the oil pump 21 stops supplying oil to the inlet pipe 23, and the oil in the hydraulic cylinder 12 flows back to the oil tank through the return pipe 22. Under the action of the piston's reverse movement, it drives the cleaning plate 32 to retract and reset, preparing for the next blockage clearing action.

[0045] The pushing device 3 includes: a mounting fork 31, which is connected to the output end of the hydraulic cylinder 12, and a back plate is fixedly connected to the back of the mounting fork 31; a cleaning plate 32, the top of which is inserted through the mounting fork 31, and the bottom of the cleaning plate 32 is provided with serrations; a connecting shaft 33, which is inserted between the back plate and the cleaning plate 32, and a cotter pin is inserted at the end of the connecting shaft 33; a mounting frame 34, which is fixedly installed on both sides of the cleaning plate 32; and an adjustable rolling mechanism 35, which is mounted on the mounting frame 34. 5 is used to provide rolling support for the movement of the mounting frame 34. After the relative position between the back plate and the cleaning plate 32 is inserted through the connecting shaft 33, the end of the connecting shaft 33 is positioned by the cotter pin to ensure the stability of the insertion of the connecting shaft 33. Thus, the installation of the relative position of the mounting fork 31 and the cleaning plate 32 can be realized. The cement outlet is generally flat and duckbill-shaped. The adjustable rolling mechanism 35 is pressed against the inner wall of the outlet. When the pushing device 3 moves linearly, the adjustable rolling mechanism 35 provides rolling support on the inner wall of the outlet, thereby making the linear movement of the cleaning plate 32 more stable.

[0046] Specifically, the adjustable rolling mechanism 35 includes: an elastic support assembly that slides through both sides of the mounting frame 34; and a position adjustment assembly installed inside the mounting frame 34 for adjusting the position of the elastic support assembly relative to the mounting frame 34. The elastic support assembly includes: a telescopic rod 351 that slides with the side of the mounting frame 34; a roller 352 that is mounted on one end of the telescopic rod 351 via a bracket; a pressing plate 353 that is fixedly connected to the other end of the telescopic rod 351, and a first inclined surface is formed on the telescopic rod 351; and a spring 354 that is movably sleeved on the outside of the telescopic rod 351. The position adjustment assembly includes: a lead screw 355, which is rotatably mounted inside the mounting bracket 34; a push block 356, which is threadedly engaged with the lead screw 355 via a nut seat, and has a second inclined surface on both sides of its bottom, which engages with the first inclined surface; a slider 357, which is fixedly connected to both sides of the push block 356; and a slide rail 358, which is installed on both sides inside the mounting bracket 34, with the slider 357 slidingly engaged with the slide rail 358. The roller 352 rolls against the inner wall of the discharge port, facilitating the movement of the cleaning plate 32 and improving its movement. The telescopic rod 351 facilitates the adjustment of the roller 352. The position is supported by the compression deformation of the spring 354, which facilitates the elastic support of the extrusion plate 353, so as to perform the retraction and reset action of the roller 352. Through the cooperation between the first inclined surface of the extrusion plate 353 and the second inclined surface of the push block 356, the extrusion plate 353 can be pushed by the force component. The linear vertical movement of the push block 356 can push the rollers 352 on both sides to move apart, so as to achieve the purpose of fine adjustment of the position of the rollers 352 by the width of the discharge port. This makes the support of the adjustable rolling mechanism 35 more flexible. The slide rail 358 facilitates the limiting of the sliding of the slider 357, making the linear movement of the push block 356 more stable.
