Description

Technical Field

[0001] This utility model relates to the field of belt conveyor, specifically a mechanism for rapid transport of steel samples using multiple belts. Background Technology

[0002] Currently, in well-known automated metallurgical laboratories, the sample receiving system and the sample preparation and analysis system are located together and directly connected. However, existing steel sample transfer technologies have many limitations in practical applications. Firstly, laboratory settings are often constrained by existing equipment layouts, with densely packed instruments, limited space, and immobile equipment. Traditional transfer mechanisms are mostly linear or fixed-path designs, making it difficult to adapt to the turning requirements in complex spaces. This results in obstacles preventing automatic connection between the sample receiving and sample preparation systems, necessitating manual sample handling, which is not only inefficient but also carries the risk of human error.

[0003] On the other hand, existing belt conveyor mechanisms have obvious defects in steering connection and speed control. The steering part lacks a reasonable transition structure and protective design, which can easily cause side tipping and jamming during steel sample transmission. The speed matching of multiple transmission belts is poor. It is difficult to maintain the momentum stability of the steel sample during high-speed transmission, and it cannot effectively reduce the inertial effect during low-speed positioning, resulting in insufficient final positioning accuracy. At the same time, the height connection design of the transmission mechanism is unreasonable. Excessive height difference can easily cause impact damage to the steel sample and affect the transmission stability.

[0004] Manual operation cannot achieve the working efficiency of a fully automated sample preparation and analysis system. Under such conditions, designing a mechanism for stable sample transfer across obstacles is a major challenge. It is necessary to ensure sample posture, stable transfer, and maximize overall efficiency. This is a problem that has plagued the expansion, upgrading, and transformation of metallurgical laboratories.

[0005] Currently, servo motors are known to control speed and position with very high accuracy, converting voltage signals into torque and speed to drive the controlled object. Planetary gear reducers are precision industrial transmission devices that achieve multi-stage speed reduction and torque amplification through the meshing structure of a sun gear, planet gears, internal gear ring, and a gear carrier. Their core function is to reduce speed and increase output torque. This product adopts a modular design and boasts advantages such as small size, high load capacity (maximum torque up to 2.6 million Nm), and smooth transmission. It is widely used in hoisting and transportation, metallurgy and mining, CNC machine tools, industrial robots, and new energy equipment. Frequency converters are power control devices that use frequency conversion technology and microelectronics to control AC motors by changing the frequency of the motor's power supply.

[0006] Therefore, there is an urgent need for a steel sample transfer mechanism that can adapt to complex spatial layouts, achieve stable steering, precise positioning, and a high degree of automation, in order to solve the aforementioned pain points of existing technologies.

[0007] Therefore, based on its many years of experience in design, development and actual production in the relevant industry, the applicant has studied and improved the existing structure and its shortcomings, and provided a mechanism for rapid transmission of steel samples by multiple belts, in order to achieve a more practical purpose.

It is an obtuse angle turning connection component of the two belt conveyors, used to realize the fine adjustment of the obtuse angle direction of the steel sample from the belt conveyor B to the belt conveyor C, and further adapt to the laboratory layout.

[0016] The belt conveyor C is a long strip belt transmission structure with side guards on both sides. Its front end is connected to the rear end of the obtuse angle connector, and its end is equipped with a V-shaped positioning block, which is the final positioning section of the transmission system. It runs at a low speed to reduce the transmission speed and reduce the effect of inertia, so as to accurately transport the steel sample to the V-shaped positioning block at the end and complete the final positioning of the steel sample.

[0017] Preferably, belt conveyor A, right-angle connector and belt conveyor B adopt a height stepped design, with the height decreasing by 1-3 mm in turn, to guide the steel sample to slide smoothly into belt conveyor B by inertia, avoiding jamming or tilting.

[0022] (III) Beneficial Effects

[0023] This invention provides a multi-belt rapid steel sample transport mechanism, which, compared with existing technologies, has the following advantages: It improves the working efficiency of fully automated sample preparation and analysis systems. By utilizing three belt conveyors in different directions, and achieving 90° turning via right-angle connectors and fine-tuning via obtuse-angle connectors, it can flexibly bypass existing laboratory equipment obstacles. This solves the problem that traditional linear transport mechanisms cannot adapt to densely packed equipment and space-constrained scenarios, meeting the cross-regional transport needs of rigid layouts in metallurgical laboratories, etc.

[0024] The side guards on both sides of the belt conveyor and the arc-shaped side guards of the connector effectively prevent the steel sample from tipping over; the 1-3 mm height step design of belt conveyor A, right-angle connector and belt conveyor B guides the steel sample to slide smoothly into the next transmission section by inertia, avoiding jamming or tilting; the coplanar connection design of belt conveyor B, obtuse-angle connector and belt conveyor C eliminates the impact of height difference, ensures the stability of the steel sample after turning, and significantly reduces the probability of failure during transmission.

[0025] Through precise three-level speed adjustment, belt conveyor A starts smoothly at low speed to carry the steel sample, belt conveyor B runs at high speed to maintain momentum and achieve rapid obstacle crossing, and belt conveyor C runs at low speed to reduce the influence of inertia.

[0028] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 As shown, this utility model provides a technical solution: a mechanism for rapid transport of steel samples using multiple belts, including belt conveyors and connectors. The belt conveyors include belt conveyor A1, belt conveyor B3, and belt conveyor C5; the connectors include right-angle connector 2 and obtuse-angle connector 4.

[0030] The main body of belt conveyor A1 is a long strip belt transmission structure with side guards on both sides to prevent the steel sample from tipping over during transmission. It is the starting section of the transmission. Its end is connected to the front end of right-angle connector 2. It is the first bearing component for the steel sample to enter the transmission system and is used to bear the racket-shaped steel sample that has been corrected and is lying flat.

[0031] The right-angle connector 2 has an arc-shaped baffle on the side and is a 90° right-angle transition structure. Its front end is connected to the end of the belt conveyor A1 and its rear end is connected to the front end of the belt conveyor B3. It is a 90° turning connection component between the two belt conveyors.

[0032] Furthermore, the arc-shaped retaining edge is set on the inside of the right-angle connector 2, that is, the inner edge of the 90° right-angle bend.

[0033] The main body of belt conveyor B3 is a long strip belt transmission structure with side guards on both sides. Its front end is connected to the rear end of right-angle connector 2 and its end is connected to the front end of obtuse-angle connector 4. It is the core acceleration section for obstacle crossing transmission and is used to receive the steel sample after it has turned through right-angle connector 2. It maintains the momentum of the steel sample through high-speed operation to ensure that it enters the next turning stage stably.

[0034] The obtuse angle connector 4 also has an arc-shaped stop on its side. Its front end is connected to the end of belt conveyor B3 and its rear end is connected to the front end of belt conveyor C5. It is an obtuse angle turning connection component between the two belt conveyors, used to realize the fine adjustment of the obtuse angle direction of the steel sample from belt conveyor B3 to belt conveyor C5, and further adapt to the laboratory layout.

[0035] Furthermore, the arc-shaped retaining edge is set on the inside of the turn of the obtuse angle connector 4, that is, the inner edge of the obtuse angle bend.

[0036] The belt conveyor C5 is a long strip belt transmission structure with side guards on both sides. Its front end is connected to the rear end of the obtuse angle connector 4, and its end is equipped with a V-shaped positioning block, which is the final positioning section of the transmission system. It runs at low speed to reduce the transmission speed and reduce the effect of inertia, so as to accurately transport the steel sample to the V-shaped positioning block at the end and complete the final positioning of the steel sample.

[0037] Furthermore, the V-shaped positioning block is made of HT300 wear-resistant cast iron, with a 2mm thick silicone buffer layer attached to the inside, and its Shore hardness is 60.

[0038] The belt conveyor A1, right-angle connector 2 and belt conveyor B3 adopt a height stepped design, with their height decreasing by 1-3 mm in turn. The steel sample is guided to slide smoothly into the belt conveyor B3 by inertia, avoiding jamming or tilting.

[0039] The belt conveyor B3, obtuse angle connector 4, and belt conveyor C5 are all located on the same plane. They adopt a plane connection design to avoid the impact of the steel sample caused by the height difference, and ensure the stability of the steel sample after turning, so as to prepare for the final positioning.

[0040] Belt conveyor A1 operates at a speed of 0.5-1.2 m / s.

[0041] Belt conveyor B3 serves as the high-speed transmission section, operating ahead of schedule at a speed of 3-4 meters per second.

[0042] The C5 belt conveyor operates at a low speed of 0.4-0.5 meters per second, delivering the sample to the V-shaped positioning block at the end of the belt conveyor, thus completing the rapid and smooth transfer and positioning of the entire sample.

[0043] Furthermore, belt conveyors A1, B3, and C5 employ 57 series servo motors (with power of 0.2kW / 0.75kW / 0.2kW) + planetary gearboxes (with reduction ratios of 1:5 / 1:10 / 1:5), and achieve stepless speed adjustment through frequency converters;

[0044] Furthermore, the inverter uses Mitsubishi FR-D740 to achieve stepless speed adjustment, ensuring a stable high-speed output of 3-4 m / s.

[0045] Furthermore, the belt conveyor uses a polyurethane synchronous belt with a diamond-shaped anti-slip pattern added to the surface. The pattern depth is 1 mm, and the friction coefficient is increased to 0.8 to prevent the steel sample from slipping during high-speed transmission.

[0046] Furthermore, the drive pulley and driven pulley are made of 45# steel with a diameter of 80mm and chrome-plated surface; the belt is a polyurethane synchronous belt with a pitch of 5mm. The tension is adjusted by a screw-type tensioning mechanism at the driven end, with a tension range of 50-100N. The tensioning pulley has a diameter of 50mm and an adjustment stroke of 20mm.

[0047] Furthermore, the frame of the belt conveyor mechanism is constructed using 2020 series aluminum profiles, which are lightweight yet high-strength and support modular installation.

[0048] Furthermore, the belt conveyor mechanism and connector are connected via 8mm thick flange bolts, and the aluminum profile frame is assembled using M8 hex bolts, with a frame verticality error of ≤1mm / m. The precise connection of the aluminum profile structure using M8 hex bolts ensures stable frame assembly and also meets the requirements for modular installation with easy disassembly and adjustment.

[0049] Furthermore, right-angle connector 2, obtuse-angle connector 4, and arc-shaped retaining edge are manufactured using 2mm thick stainless steel sheet metal forming and welding processes, combining the belt conveyor into a multi-belt high-speed transmission mechanism.

[0050] Furthermore, a 5mm thick silicone buffer layer with a Shore hardness of 60 is pasted on the inner side of the arc-shaped retaining edge on the side of the connector to reduce the impact force when the steel sample collides, reduce noise, and avoid scratches on the surface of the steel sample; the pasting process uses acrylic structural adhesive, and the curing time is 24 hours.

[0051] Furthermore, the arc radius of the curved retaining edge of the right-angle connector 2 and the obtuse-angle connector 4 is 120mm, corresponding to 1 / 4 of the circumference, and the retaining edge height is 30mm. The inner side transitions tangentially with the edge of the belt, and the gap at the joint is ≤1mm. The obtuse angle of the obtuse-angle connector 4 is 135°±5°.

[0052] Furthermore, dust collection troughs can be added to the bottom of right-angle connector 2 and obtuse-angle connector 4. The dust collection troughs are installed by snap-fit, are 50mm wide and 10mm deep, and have Φ10mm dust discharge holes. They are used for negative pressure ventilation with an air volume of 5m³ / h to promptly clean up steel slag and dust that fall during transmission and prevent accumulation and blockage.

[0053] Furthermore, emergency stop buttons with protective covers can be installed every two meters along the transmission path, and protective railings with a height of 500mm and a mesh size of ≤20mm can be installed on both sides of the conveyor belt to prevent personnel from accidentally touching them or the steel sample from falling accidentally.

[0054] Furthermore, it is specified that the applicable steel sample is a racket-shaped steel sample with a length of 200-500mm, a width of 50-150mm, a thickness of 5-20mm, and a weight of ≤5kg. It is ensured that the belt width of 120mm and the edge height of 28mm match the size of the steel sample to avoid tipping or displacement.

[0055] Working principle: Belt conveyor A1 carries the racket-shaped steel sample, which has been corrected and is lying flat, at a speed of 0.5-1.2 m / s. When the sample reaches the end of belt conveyor A1, due to inertia, it falls onto the slightly lower right-angle connector 2 and collides with the arc-shaped guard of right-angle connector 2, changing its direction of motion and sliding along the arc-shaped guard to the slightly lower belt conveyor B3. Belt conveyor B3 starts ahead at a speed of 3-4 m / s, continuing to rapidly transfer the sample. After a slight change in direction via obtuse-angle connector 4, it reaches the already started belt conveyor C5. Belt conveyor C5 delivers the sample to the V-shaped positioning block located at the end of the belt conveyor at a speed of 0.4-0.5 m / s, completing the rapid and smooth transfer and positioning of the entire sample.

[0056] Example 1: First, three belt conveyors are manufactured, each with a width of 120mm, a sidewall height of 28mm, and lengths of 2 meters, 15 meters, and 3 meters. These are respectively hoisted at the junction of the pneumatic robot circle, the wall, and above the reserved opening of the sample preparation and analysis robot circle, 2 meters above the ground.

[0057] Right-angle connector 2 is manufactured using 2mm thick stainless steel sheet, employing sheet metal forming and welding processes. Its curved flange is 30mm high and has a radius of 120mm (1 / 4 of a circle). Obtuse-angle connector 4 is manufactured with an obtuse angle of 135° and a flange height of 30mm.

[0058] Next, install the connecting belt conveyor A1, right-angle connector 2, and belt conveyor B3, adjusting their heights to decrease by 1.5mm in sequence; then install the obtuse-angle connector and adjust the heights of the belt conveyors at both ends to be aligned.

[0059] Then, the speeds of the three conveyor belts were adjusted sequentially to 0.5 m / s, 3 m / s, and 0.4 m / s, respectively, while testing the stability and positioning repeatability of the samples. The speeds were gradually increased before setting the parameters. Finally, the automatic obstacle-crossing transport of the samples was completed.

[0060] Example 2: A metallurgical testing laboratory originally had one 3500 system. To meet production needs, another 3500 system was to be installed. However, the existing sample transfer equipment already occupied the space between the pneumatic sample feeder and the new 3500 system. The existing laboratory had many instruments, and the layout could not be moved, thus the installation space was occupied. The sample receiving system and sample preparation system were also far apart, making automatic sample transfer impossible; manual sample handling was the only option. To achieve automatic sample transfer, an alternative solution must be found that overcomes these obstacles.

[0061] After applying this device, samples from laboratory tests can be transported to the new 3500 system via belt conveyors in different directions, eliminating the need for manual sample handling and greatly improving the level of automation in the laboratory. This multi-belt rapid sample transport mechanism can operate 24 hours a day, enhancing work efficiency and automation levels.

[0062] Example 3: In the furnace area of ​​the steel plant, a steel sample with a length of 350mm, a width of 120mm, a thickness of 15mm, and a weight of 4kg after high temperature cooling needs to be hoisted 1.8 meters above the ground by a 3-meter-long belt conveyor A1, a 20-meter-long belt conveyor B2 around the workshop wall, and a 2-meter-long belt conveyor C5 connected to the quality inspection workshop testing platform.

[0063] The right-angle connector has an arc radius of 120mm, a flange height of 30mm, and a 5mm silicone buffer layer pasted on the inside; the obtuse-angle connector has an angle of 130°, a dust collection groove at the bottom with a width of 50mm and a depth of 10mm, and a negative pressure exhaust air volume of 6m³ / h.

[0064] The heights of belt conveyor A1, right-angle connector 2, and belt conveyor B3 decrease by 2mm in sequence; the heights of belt conveyor B3, obtuse-angle connector 4, and belt conveyor C5 are aligned.

[0065] Belt conveyor A1 runs at 0.8 m / s, belt conveyor B3 starts ahead at 3.5 m / s, and belt conveyor C5 runs at 0.45 m / s.

[0066] The belt is equipped with 500mm high guardrails on both sides with 15mm mesh size. An emergency stop button is installed every 1.5 meters along the transmission path. The belt is a heat-resistant polyurethane synchronous belt.

[0067] In summary, this method improves the efficiency of the fully automated sample preparation and analysis system. By utilizing three belt conveyors in different directions, and achieving 90° turns through right-angle connectors and fine-tuning of direction through obtuse-angle connectors, it can flexibly bypass existing equipment obstacles in the laboratory. This solves the problem that traditional linear transmission mechanisms cannot adapt to densely packed equipment and space-constrained scenarios, and meets the cross-regional transmission needs of rigid layouts such as metallurgical laboratories.

[0068] The side guards on both sides of the belt conveyor and the arc-shaped side guards of the connector effectively prevent the steel sample from tipping over; the 1-3 mm height step design of belt conveyor A, right-angle connector and belt conveyor B guides the steel sample to slide smoothly into the next transmission section by inertia, avoiding jamming or tilting; the coplanar connection design of belt conveyor B, obtuse-angle connector and belt conveyor C eliminates the impact of height difference, ensures the stability of the steel sample after turning, and significantly reduces the probability of failure during transmission.

[0069] Through precise three-level speed adjustment, belt conveyor A starts smoothly at low speed to carry the steel sample, belt conveyor B runs at high speed to maintain momentum and achieve rapid obstacle crossing, and belt conveyor C runs at low speed to reduce the influence of inertia. Together with the V-shaped positioning block at the end, it achieves precise positioning of the steel sample, which not only ensures the transmission efficiency, but also improves the positioning accuracy to a level that meets the testing requirements.
