Problems solved by technology
The counterweight is connected to the upper platform of the excavator by bolts. During the use of the excavator, rainwater, etc. flow into the bolt holes, which is extremely difficult to evaporate. In cold areas, the water will freeze and expand, which will cause additional damage to the counterweight bolt connection. Axial force weakens the bolt connection strength, and after water enters the bolt hole, it is easy to corrode the matrix and damage the connection pair, thereby affecting the service life

Embodiments of the present invention provide a waterproof structure and an excavator, which relate to the technical field of construction machinery equipment. The waterproof structure provided by the embodiment of the present invention includes a frame body, a counterweight structure, an adjusting gasket and a blocking member. The frame body is provided with connection holes. A through groove is opened on the adjusting gasket, and a notch communicating with the through groove is provided on the periphery of the adjusting gasket. The adjusting gasket is arranged between the counterweight structure and the frame body, and part of the counterweight structure passes through the slot to be located in the connecting hole. The blocking piece is fixedly connected to the frame body, and the blocking piece is set corresponding to the notch to cover the notch, thereby preventing water from flowing into the connection hole from the notch, thereby avoiding the impact of water on the counterweight structure, and helping to extend the life of the counterweight structure. service life.
Description
technical field [0001] The invention relates to the technical field of construction machinery equipment, in particular to a waterproof structure and an excavator. Background technique [0002] Construction machinery is the necessary mechanical equipment in the process of engineering construction, and in the process of engineering construction, the working environment of machinery is harsh. [0003] For example, for excavators, most of the excavators are equipped with counterweights at the rear of the upper platform to balance the vehicle. The counterweight is connected to the upper platform of the excavator by bolts. During the use of the excavator, rainwater, etc. flow into the bolt holes, which is extremely difficult to evaporate. In cold areas, the water will freeze and expand, which will cause additional damage to the counterweight bolt connection. The axial force weakens the bolt connection strength, and after water enters the bolt hole, it is easy to corrode the matri...
