However, since the two ends of the elastic hanger are respectively connected to the exhaust pipe fittings and the hull, and they are all welded by the connectors, the welding deformation is difficult to control, so the installation accuracy and welding deformation of the elastic hanger components cannot be guaranteed. In addition, it is difficult to protect the elastic elements from welding spatter during welding, so it is necessary to replace the elastic hanger components by making templates for the elastic hanger components to position the hull support and air pipe support on site
After positioning and welding, the installation accuracy is ensured by brushing and adjusting the gasket. However, because the hole position accuracy of the upper and lower installation surfaces of the elastic hanger is very high, it is necessary to drill holes on site, which greatly increases the installation cost. Difficulty directly leads to an increase in installation costs, increases the production cycle, increases labor intensity, and also affects the parallelism of the elastic hanger, the verticality of the installation hole and the accuracy of the uniformity, and there are quality risks, leaving behind quality risk

The invention discloses a ship broadside exhaust pipe elastic suspension connecting device which comprises a first support connected with a ship body, and a second support connected with an elastic suspension assembly. The first support and the second support are connected through at least one group of adjustable connecting assembly; each adjustable connecting assembly comprises a first connectingpiece connected with the first support, and a second connecting piece connected with the second support; the first connecting pieces and the second connecting pieces are in threaded connection through sleeve pipes; and through holes are formed in the first support and the second support, so that the first support and the second support can be conveniently centered and adjusted. According to the ship broadside exhaust pipe elastic suspension connecting device provided by the invention, a preassembling manner of a pre-manufacturing mold plate is replaced, and no manual spacer grinding or physical drilling construction operation is needed, so that the cost is reduced, the labor intensity is relieved, the efficiency is improved, and the quality risk is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of elastic hangers, in particular to a connection device and an installation method of an elastic hanger for ship side exhaust pipes. Background technique [0002] At present, the exhaust pipe system of marine diesel engines, especially the side exhaust pipe, needs to be hanged under the ceiling of the engine room for vibration damping installation, and elastic vibration damping installation is usually used. Due to the installation size of elastic shock absorbers such as elastic hangers, The precision requirements are very high, and it is especially required to ensure that the force of each coil spring is uniform, and the installation surfaces at the upper and lower ends are parallel, and no twisting or skewing is allowed to ensure that the force of each coil spring is uniform and consistent. Therefore, the installation requirements of the elastic hanger very high. However, since the two ends of the elastic...
