[0023] It should be noted that the following detailed description is exemplary and is intended to further explain the present application. Unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0024] The expansion water tank is also called a radiator expansion tank, and is a key component in the cooling system of the excavator. The main function is to accommodate the part increased due to the thermal expansion of the coolant, to prevent the coolant from overflowing, and to maintain the pressure stability of the cooling system. When the excavator is working, the coolant circulates and flows, absorbs the heat generated by the engine, and is dissipated to the outside through the radiator. The traditional excavator expansion water tank is directly fixed above the radiator, the space utilization rate above the radiator is low, and it also causes the installation cabin height of the excavator to be high, which causes inconvenience in transportation and maintenance, and blocks the view during driving; and the traditional excavator generally opens a small door on the upper machine cover for filling, and the expansion water tank is placed on the radiator, so that additional filling tooling is required during filling. Since the expansion water tank of the excavator is above the radiator, it is not convenient to fill the coolant, and it is also not convenient to observe the liquid level, and the coolant cannot be supplemented in time according to the actual needs.

[0025] The present application will be described in detail below with reference to the accompanying drawings. The excavator expansion water tank 2 installation structure disclosed in the present embodiment, as shown in Figure 1 The lower end of the first mounting plate 3 is mounted with the second mounting plate 6, the upper end of the second mounting plate 6 is connected with the lower end of the expansion water tank 2, and the side part of the first mounting plate 3 is connected with the side part of the expansion water tank 2; the machine shell 1 is provided with a coolant filling window 7, and the lower end of the coolant filling window 7 is provided with an observation window 8.

[0026] The expansion water tank 2 is installed by cooperation of the first mounting plate 3, the second mounting plate 6 and the machine shell 1, the expansion water tank 2 is placed alone, the side is fixed, the space above the radiator is released, and the overall height is reduced; and the coolant filling window 7 and the observation window 8 are arranged on the machine shell 1, which facilitates filling of the coolant and observation of the liquid level of the coolant, and timely supplement of the coolant.

The cooling liquid filling window 7 is used for filling cooling liquid. When the cooling liquid is insufficient, the filling opening of the expansion water tank 2 is opened, and the expansion water tank 2 is filled with cooling liquid. Through the design of the cooling liquid filling window 7, the cooling liquid can be filled from the side, which is convenient for filling and improves the efficiency of filling the cooling liquid.

[0029] The observation window 8 is a circular hole, and the observation window 8 is aligned with the tank body of the expansion water tank 2. The amount of cooling liquid in the expansion water tank 2 is observed through the observation window 8, so that the cooling liquid can be supplemented in time when the cooling liquid is insufficient. A plurality of square holes 9 are arranged at both ends of the observation window 8.
