Problems solved by technology
The existing conventional seals are complicated to install, and it is difficult to ensure reliable sealing when the reamer shakes
Especially when installing the seal, it is usually necessary to open installation grooves on the end face of the original reamer shaft seat and the end face of the drive device (such as a gearbox), which destroys the original structure and easily leads to deterioration of the stress on the structural parts, resulting in Stress concentration, lack of strength
At the same time, improving the structure (opening installation grooves, etc.) is time-consuming and labor-intensive, especially inconvenient to operate on the job site, and the installation and replacement of the seal is time-consuming and laborious

The invention creatively provides a non-destructive quick-mounting seal of a dredger. The non-destructive quick-mounting seal comprises an elastic buffering part and connecting parts on the two sidesof the elastic buffering part; the surfaces of the connecting parts are provided with end surface sealing parts; each end surface sealing part comprises two sealing lips at the same height, and a buffer groove is formed between the two sealing lips; and a plurality of connecting holes are formed in the bottoms of the buffer grooves. The seal provided by the invention is simple in fixing mode and can be conveniently mounted without modifying structural parts of an original reamer part and structural parts of a driving device end, structural damage is small, and the mounting and dismounting efficiency is high. Moreover, the seal can also be used as a temporary seal and can be quickly mounted at the position needing to be sealed.
Description
technical field [0001] The invention belongs to the technical field of seals for dredgers, and in particular relates to a non-destructive quick-installation seal for dredgers. Background technique [0002] Cutter suction dredger is a kind of ship widely used in beach dredging projects. It uses the front end of the suction pipe to install a rotary reamer device around the suction pipe to cut and stir the river bottom sediment, and then through suction dredging The tube transports the hoisted sediment material to the sediment material accumulation field with the help of powerful pump force, and the processes of dredging, transporting and unloading can be completed continuously at one time. In fact, the reamer part and the device driving the reamer also need to be sealed to prevent seawater from intruding into the equipment, and also to prevent the oil in the equipment (hydraulic oil in the case of hydraulic drive device / gear oil in case of gearbox drive) ) seeps into seawater...
