Розрахунок та конструювання такелажного візка для перевезення великогабаритних і великовагових вантажів на автотранспортних підприємствах та складських комплексах

Abstract

During reloading and unloading, large and heavy loads are sometimes difficult to handle, which sometimes endangers human health or even life. This paper considers the problem of using lifting and transport equipment under the condition of safe transportation of large and large loads in the conditions of a motor transport enterprise or cargo complex. Heavy and bulky loads or other structures are transported by means of rigging devices and specialized equipment, such as rigging carts, without which many different industries will have problems transporting the heavy loads required for proper performance. On the basis of previously conducted analytical research, the authors propose the design of a rigging trolley with four support rollers. The purpose of the research is to establish the distribution of reactions on the axis of the rigging trolley during transportation of heavy or bulky cargo and to conduct a detailed force calculation of the proposed design of the rigging trolley for strength from load of different sizes. With the help of the СAD / CAM system of Solidworks, the simulation of the trolley operation under the load of conditional heavy and oversized cargo was carried out. This allowed to obtain the dependence of the deformation of the bearing surface of the rigging trolley on the force acting on it. The reseach shows the distribution of forces on the supporting surface of the rigging truck. The reactions that occur at the reference points of the structure are calculated. The distribution of reactions on the axis of the designed rigging trolley during transportation of large and heavy cargo is carried out. This made it possible to determine the force that must be applied to the load to move it out of place.
