Detailed Description

The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.

Referring to fig. 1 to 4, the utility model discloses a condenser installation damping structure, including mounting panel 1, fix joint board 2 in condenser 8 both sides, the arch is fixed at the positive supporting beam 3 of mounting panel 1 and is connected a bolt 4 with a supporting beam 2 and a supporting beam 3, be provided with damping assembly between bolt 4 and a supporting beam 3, damping assembly includes that the suit is at 5 and the suit is at 5 outlying damping pad 6 of damping pad spacer, the last recess 61 of having seted up of damping pad 6, the recess 61 joint is on joint board 2 and two radial terminal surfaces of recess 61 compress tightly respectively on two sides of joint board 2, the terminal surface of damping pad 6 compresses tightly on a supporting beam 3's terminal surface, the clearance has between the terminal surface of 5 of damping pad spacer and the terminal surface of a supporting beam 3. When condenser 8's installation, can guarantee through this clearance that the terminal surface of damping pad 6 compresses tightly on a supporting beam 3's terminal surface to can prevent that damping pad spacer 5 from causing the interference to damping pad 6's compressive deformation, make two radial terminal surfaces of recess 61 on the damping pad 6 compress tightly respectively on two sides of joint plate 2 simultaneously, in order to guarantee condenser 8's firm installation. Meanwhile, the supporting beam 3 is fixed on the mounting plate 1 in a protruding mode, a certain gap exists between the condenser 8 and the mounting plate 1, the condenser 8 is prevented from being greatly vibrated due to the fact that the condenser 8 is directly mounted on the mounting plate 1, and the cooling effect of the condenser 8 on the excavator can be guaranteed.

Preferably, the inner diameter of the vibration damping spacer 5 is larger than the diameter of the screw of the bolt 4, so that the vibration damping spacer 5 can be conveniently sleeved on the screw of the bolt 4.

Preferably, the inner diameter of the damping washer 6 is adapted to the outer diameter of the damping washer spacer 5.

Preferably, the clamping plate 2 is provided with a clamping groove 21, and the clamping groove 21 is in a U shape with an opening facing outward, so that the damping pad 6 is conveniently clamped in the clamping groove 21.

Preferably, the width of the clamping groove 21 is smaller than that of the groove 61, so that the clamping plates 2 on two sides of the condenser 8 can be conveniently and smoothly clamped in the groove 61 of the damping pad 6 during installation.

Preferably, the mounting surface of the snap plate 2 is convexly arranged toward one side of the condenser 8, so that when the condenser 8 is mounted on the support beam 3, a gap is formed between the side surface of the condenser 8 and the side surface of the support beam 3, thereby preventing the side surface of the condenser 8 from directly contacting the side surface of the support beam 3, preventing the condenser 8 from being affected by vibration of the support beam 3, and ensuring the heat dissipation effect of the condenser 8.
