Structural features of self-propelled hoist conveying system

Thread Content

Introduction to the mechanical part of the self-propelled hoist conveying system: 1. The track of the self-propelled hoist system of the track structural parts coating (shot blasting) production line uses I-beam (I36a) as a special track. 2. The busbar of the sliding contact rail is molded from copper and has a C-shaped cross-section. It is fixed on the track web through accessories such as insulating sleeves and fixed brackets, and then the sliding wire is embedded in the bracket in parallel. Its function is to provide the working power supply for the drive motor and chain hoist as well as the required signals for the PLC for the carrier. Our company adopts domestically produced sliding conductors with imported German technology. Compared with other types of sliding conductor rails, this C-type flame-retardant sliding conductor rail has the characteristics of simple structure, high strength, and good rigidity. In particular, the unique power supply connector connection type fully ensures the reliability of the power supply. The fully flame-retardant sheath and current collector ensure the safety of the sliding conductor system. The insulation sleeve is made of flame-retardant materials. The technical parameters are as follows: Model Rated Voltage Rated Current Bending Radius (My hands hurt after writing so much, please vote for your precious points, thank you) C-25/100 600v/50Hz 120A R≥1000mm 3. The current collector is made of products imported from Germany and matched with the C-type sliding contact wire. The collector brush blade is made of copper-based graphite powder metallurgy and high-temperature die-casting, which has good electrical conductivity, wear resistance, and self-lubricating function; the current collector arm is articulated and made of aluminum alloy arm material, which has good strength, is not easy to break and age, has good durability, and has a rated current of 120A. 4. The self-propelled hoist conveying system of the structural parts painting (shot blasting) production line of the carrier truck adopts a domestic dual-drive carrier truck, which is a two-type vehicle unit with a power of 0.4KW × 2, a rated load of 10 tons, a running speed of ≥18m/min, and frequency conversion speed regulation in the shot blasting room of 0.5~2.0m/min. The design of the carrier fully considers the rationality of maintenance. Bolts are used to connect parts and components, which is very practical. It has the characteristics of reasonable structure, intuitive and easy maintenance, and has the advantages of smooth operation, low noise and reliable use. The cargo trolley is equipped with a special lateral guide wheel, which can effectively suppress and slow down the lateral swing of the trolley. Each group of trolleys adopts a balancing beam structure, which can effectively reduce the front and rear shaking when parking and starting; ensure the smooth operation of the trolley and good contact between the current collector brush and the conductive sliding wire, and reduce the phenomenon of sparks caused by incorrect contact. This project uses two types of cargo trucks with double lifting points, as shown in the figure below: the distance between the two hooks is Lk=2800mm, and each cargo truck is equipped with two chain hoists to achieve different functions such as lifting and lowering workpieces. 5. The turnout function is to realize the diversion and merging functions by changing the operating route of the cargo trolley. The structural parts are painted (shot blasted) The cab and thin plate pre-processing production lines are respectively equipped with working and maintenance turnouts, which are closed by electric push rods. The turnouts are reinforced with supporting plates so that the allowable sinking of the turnouts is controlled within the range of ≤2mm. 6. Electric chain hoist The electric chain hoist is an important component of the self-propelled hoist. Its quality directly affects the reliability of the system, and thus affects the production rhythm. The self-propelled hoist conveying system of this structural part coating (shot blasting) production line uses domestically introduced technology PK type electric chain hoist. Each trolley of the load truck is equipped with two chain hoists, and the hoist is lifted and lowered through PLC program control or button operation. 7. Workpiece spreader The spreader of this structural part coating (shot blasting) production line must be designed and manufactured in conjunction with the workpiece. The spreader of this production line should be suitable for a variety of structural parts of different sizes. This post was last edited by lq6003 on 2008-11-28 15:15 ]
