Technical Field

[0001] The present invention relates to the technical field of transportation devices, and in particular to loading and unloading equipment and a method for cutting refractory bricks. Background Art

[0002] In order to improve the working environment of the cutting personnel, a negative pressure dust suction device is usually installed on the inside of the cutting equipment. At the same time, it is combined with an automatic control device and an automatic clamping device to complete the semi-automatic cutting of refractory bricks. Due to the large mass and high overall density of refractory bricks, the loading and unloading process is mostly carried out manually. During the loading and unloading process, the dust around the cutting equipment is still relatively large.

[0003] The turntable-type limiting structure allows the operator to clamp and load and unload refractory bricks at a distance, but the distance between the operator and the cutting point depends on the radius of the turntable structure.

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and examples.

[0027] Refractory bricks contain a large amount of metal materials inside. They have a large overall mass and high density, and can withstand high temperatures. They are an important raw material for building smelting furnaces.

[0028] In order to meet the construction of the smelting furnace body, refractory bricks need to be cut into predetermined shapes and sizes. Due to the high density and heavy weight of refractory bricks, the cutting of refractory bricks is carried out by special cutting equipment. Due to the special material of refractory bricks, the cutting time is long and the dust is large during the cutting process.

[0029] In order to improve the working environment of the cutting personnel, a negative pressure dust suction device is usually installed on the inside of the cutting equipment. At the same time, it is combined with an automatic control device and an automatic clamping device to complete the semi-automatic cutting of refractory bricks. Due to the large mass and high overall density of refractory bricks, the loading and unloading process is mostly carried out manually. During the loading and unloading process, the dust around the cutting equipment is still relatively large.

[0030] The turntable-type limiting structure allows the operator to clamp and load and unload refractory bricks at a distance, but the distance between the operator and the cutting point depends on the radius of the turntable structure. In order to compress the volume of the equipment, its design size is usually limited, and the operator is still located on the side close to the cutting equipment; some designs use a clip-type structure design, which cooperates with the push plate and the storage box to realize automatic loading of refractory bricks during the movement of the push plate; however, due to the large mass of the refractory bricks, the push plate will generate greater friction with the surface of the cutting equipment during the process of pushing the refractory bricks to move, thereby reducing the service life of the local part of the equipment.

[0031] In order to solve the above problems, refer to the attached Figure 1 -Attached Figure 7 A loading and unloading equipment for cutting refractory bricks includes a first conveying device 200. A clamping device 500 for fixing the refractory bricks 300 is provided on the upper surface of the first conveying device 200. The first conveying device 200 drives the refractory bricks 300 to move in a directional manner to complete the cutting. The refractory bricks 300 can be fixed to the surface of the first conveying device 200 through the clamping device 500 to ensure their stability during the subsequent cutting process; at the same time, the first conveying device 200 can move along the first direction, that is, move toward the cutting end 110, move to the predetermined cutting area, and cooperate with the cutting end 110 to complete the cutting of the refractory bricks 300.

[0032] Specifically, the first conveying device 200 includes a first conveying plate 210 and a second conveying plate 230. The surface of the first conveying plate 210 is provided with a loading window 220 that passes through from top to bottom. The second conveying plate 230 is opposite to the loading window 220. The inner wall of the loading window 220 is provided with a locking device for fixing the second conveying plate 230. The locking device can lock and fix the first conveying plate 210 and the second conveying plate 230 to form a relatively fixed whole, thereby ensuring the stability of the refractory brick 300 loading process.

[0033] The second conveying plates 230 here are provided in plurality, and also include a second conveying device 400 for conveying the second conveying plates 230 and the refractory bricks 300 in a directional manner. The second conveying device 400 is located below the first conveying device 200, and a jacking device 800 is also provided at the bottom of the second conveying device 400. The second conveying plates 230 and the refractory bricks 300 are controlled to be loaded and unloaded between the first conveying device 200 and the second conveying device 400 by the jacking device 800. During the loading process of the refractory bricks 300, the second conveying plate 230 carrying the refractory bricks 300 is first moved to a predetermined position, that is, below the loading window 220, by the second conveying device 400, and then the second conveying plate 230 is controlled to move to the loading window 220 by the jacking device 800, and the second conveying plate 230 is fixed to the first conveying plate 210 by the locking device; after the two are fixed, the first conveying device 200 as a whole and the refractory bricks 300 in the clamped state are controlled to move toward the cutting end 110 to complete the cutting.

[0034] During the unloading process after the refractory bricks 300 are cut, the reverse steps of loading can be followed; when controlling the first conveying device 200 to move outward as a whole, the jacking device 800 is in a jacking state, and the locking state is released at this time. The second conveying plate 230 is initially lowered under the support of the jacking device 800 until it drops to the surface of the second conveying device 400, and then the cut refractory bricks 300 are conveyed to the outside through the second conveying device 400.

[0035] Through the above-mentioned structural design, the automatic loading and unloading of the refractory bricks 300 can be realized. Compared with the loading and unloading of the traditional push plate structure, there is no relative movement between the refractory bricks 300 and the second conveying plate 230, and no wear will be generated, thereby ensuring the service life of the overall structure; at the same time, through the cooperation of the second conveying device 400 and the first conveying device 200, the staff can be located on the outside to load and unload the refractory bricks 300, and can be located away from the cutting end 110 to load and unload the refractory bricks 300, thereby improving the working environment of the staff; at the same time, the second conveying device 400 is located below the first conveying device 200, and the height of the refractory bricks 300 lifted by the staff during the loading and unloading process is lower, thereby reducing the difficulty of the loading and unloading operations for the staff.

[0036] Please refer to the attached Figure 6 And attached Figure 7 The transverse and longitudinal cross-sections of the second conveyor plate 230 are both trapezoidal, and the inner wall of the loading window 220 is adapted to the shape of the outer wall of the second conveyor plate 230. Through the above structural design, an inclined blowing gap 221 can be formed between the second conveyor plate 230 and the first conveyor plate 210, which can limit the upper limit position of the second conveyor plate 230 and limit the second conveyor plate 230 to prevent it from exceeding the predetermined position during the upward movement, thereby ensuring the efficient and accurate locking of the locking device.

[0037] The locking device here can select a hydraulically retractable locking block, and a locking opening adapted to the locking block is opened on the side wall of the second conveyor plate 230; the locking blocks here are symmetrically arranged in two, and the locking blocks can enter the locking opening after being extended, thereby limiting the freedom of the second conveyor plate 230 and ensuring that the second conveyor plate 230 is in a relatively stable state; the locking blocks here are selected to be made of flat rigid material to increase the locking area to ensure the stability of the second conveyor plate 230 limit.

[0038] A blowing device 600 is also provided in the moving path of the first conveying device 200. The blowing device 600 is provided below the first conveying device 200 and opposite to the loading window 220. A negative pressure suction device 120 is also provided on the inside of the first conveying device 200. The blowing device 600 is provided below the cutting end 110. High-pressure gas can be blown out from bottom to top through the blowing device 600. The high-pressure gas can be blown out from the blowing gap 221 to act on the surrounding of the refractory bricks 300. On the one hand, it avoids the cutting dust from entering the blowing gap 221, ensuring the stability and accuracy of the overall structure in subsequent transportation and docking; on the other hand, the blowing device 600 can cooperate with the negative pressure suction device 120 to form a directional circulating clean airflow, so that the dust generated by cutting can flow in a directional manner, thereby realizing the rapid discharge of cutting dust.

[0039] Furthermore; the blowing device 600 here includes a U-shaped first blowing component 610 and a U-shaped second blowing component 620. The first blowing component 610 and the second blowing component 620 are symmetrically arranged. The first blowing component 610 and the second blowing component 620 are combined to form an annular blowing area, which can be adapted to the edge of the loading window 220 to achieve efficient and precise blowing control; through the above-mentioned structural design, the first blowing component 610 and the second blowing component 620 can be adapted to the edge of the loading window 220, ensuring the accuracy of the blowing outlet end; under the condition of the same air pressure, through the above-mentioned structural design, the air flow rate blown out is greater.

[0040] It should also be noted that a sealing structure can be provided on the outside of the first blowing assembly 610 and the second blowing assembly 620. After the sealing structure is extended, it can be tightly pressed against the bottom of the first conveying plate 210 to prevent the high-pressure gas from being discharged from the gap between the two, thereby ensuring the concentration of the high-pressure gas.

[0041] Furthermore, the gas pressure blown out by the first blowing component 610 is lower than the gas pressure blown out by the second blowing component 620. The first blowing component 610 and the second blowing component 620 are independently pumped and controlled. Through the above-mentioned structural design, the gas blown out from the first blowing component 610 will not have an excessive impact on the circulating airflow between the blowing device 600 and the negative pressure suction device 120, thereby ensuring the stable directional flow of cutting dust.

[0042] A lifting device 700 is also provided between the first blowing assembly 610 and the second blowing assembly 620. The lifting device 700 is electrically connected to the locking device to control the height position of the second conveying plate 230 and the refractory bricks 300. During the cutting process, the positional relationship between the second conveying plate 230 and the first conveying plate 210 can be adjusted to control the second conveying plate 230 to move downward, and the cross-sectional area of ​​the blowing gap 221 can be controlled to be larger, so that more gas can be blown out, the circulating airflow can be enhanced, and the cleaning effect of the cutting dust can be improved. The above structural design is suitable for dry cutting of refractory bricks 300 and the generation of a large amount of dust.

[0043] The second conveying plate 230 and the first conveying plate 210 are controlled to be close to each other. At this time, the cross-sectional size of the blowing gap 221 is small. At this time, the air flow rate blown out from the blowing gap 221 is fast and the flow rate is relatively small. Through the above design, large particles of cut particles can be prevented from falling into the blowing gap 221. At the same time, through the above design, it can be used in conjunction with the spray dust reduction system. When water droplets flow to the blowing gap 221, the high-pressure gas can blow the water droplets upward and atomize them again, further improving the dust reduction effect.

[0044] Furthermore, the clamping device 500 is electrically connected to the lifting device 700, and the control clamping device 500 and the lifting device 700 are electrically connected. The clamping state of the clamping device 500 can be adaptively adjusted according to the lifting state of the lifting device 700, ensuring that the refractory bricks 300 are continuously in a stable clamping state under different states; Specifically, the clamping device 500 includes a support rod 510, and the upper end of the support rod 510 is rotatably connected to the clamping rod 530, and the first end of the clamping rod 530 is connected to the first conveying device 20 0 is provided with a telescopic component 520, which is electrically connected to the lifting device 700. By controlling the telescopic component 520 to extend and retract, the deflection angle of the clamping rod 530 can be controlled. By adjusting the deflection angle of the clamping rod 530, the clamping state of the refractory brick 300 can be adjusted to achieve adaptive clamping control. At the same time, through the above-mentioned structural design, refractory bricks 300 of different thicknesses can be clamped and limited, thereby ensuring the stability of refractory bricks 300 of different thicknesses in the cutting state.

[0045] Specifically, the jacking device 800 includes a retractable jacking component 820, and a jacking plate 810 is fixed to the jacking end of the jacking component 820. A jacking positioning groove adapted to the jacking plate 810 is opened at the lower end of the second conveying plate 230. By cooperating with the jacking positioning groove, the stability of the position of the second conveying plate 230 in all directions can be ensured in the process of controlling the lifting of the second conveying plate 230, and the second conveying plate 230 and the refractory bricks 300 can be ensured to be steadily lifted; the above-mentioned jacking component 820 can be selected as a hydraulic telescopic rod, which can lift and convey refractory bricks 300 of larger mass.

[0046] The second conveying device 400 here includes an electric conveying track. The electric conveying track is annular and can be selected into two groups, inner and outer. A gap is formed between the two groups of electric conveying tracks for the jacking device 800 to pass through. The design of the electric conveying track enables the second conveying plate 230 to move in a cycle on the track. Compared with the traditional linear track, only one staff member or transfer robot is required to load and unload materials at the rated position, which simplifies the operation process and the required manpower and equipment.

[0047] Finally, it should be noted that in the process of conveying the refractory bricks 300 by the above-mentioned loading and unloading equipment, the refractory bricks 300 need to be placed at a predetermined position on the surface of the second conveyor plate 230 to ensure the accuracy of the subsequent cutting of the second conveyor plate 230. At the same time, the cross-sectional size of the refractory bricks 300 cannot be larger than the cross-sectional size of the second conveyor plate 230 to avoid being unable to pass through the loading window 220 and avoid the phenomenon of being unable to cut.

[0048] The present invention is further described below in conjunction with the method.

[0049] A method for loading and unloading materials for cutting refractory bricks, using the above-mentioned loading and unloading equipment for cutting refractory bricks, comprises the following steps:

[0050] S1. Control the second conveying plate 230 and the refractory bricks 300 to move to a predetermined position below the loading window 220 through the second conveying device 400; at this time, the first conveying device 200 is located at the outermost position, and the refractory bricks 300 are located within the horizontal projection area of ​​the loading window 220.

[0051] S2. Control the lifting device 800 to lift the second conveying plate 230 and the refractory bricks 300 to be opposite to the loading window 220. During this process, the refractory bricks 300 pass through the loading window 220 from bottom to top and gradually move to the upper end of the first conveying device 200.

[0052] S3. Fix the first conveyor plate 210 and the second conveyor plate 230 through the locking device, complete the clamping and positioning of the refractory bricks through the clamping device 500, and then move the refractory bricks 300 to the cutting area for cutting through the first conveyor device 200. During the cutting process, the first conveyor device 200 is in the innermost position, and the cutting end 110 can move in multiple directions to efficiently cut the refractory bricks 300.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
