Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific embodiments.

[0021] Such as Figure 1 to Figure 2 Shown here is an articulated dump truck suspended cooling metal pipe shock-absorbing fixed structure, including a radiator 1, a suspended cooling metal pipe 2, a first hose 3, a second hose 4, a water pump 6, a frame 8, a bolt 9, The fixed support 10, the nut 11, the U-shaped bolt 12 and the third hose 13 fixed to the frame;

[0022] One end of the suspended cooling metal pipe 2 is connected to the third hose 13 fixed to the frame, and the other end is connected to the three-way metal pipe 5 of the water pump 6 through the first hose 3; this alternate connection between the metal pipe and the hose makes full use of The thermal conductivity and processing technology of the metal tube are better than the rubber tube, and the cost is lower than that of the rubber tube. At the same time, the rubber tube is used to compensate for the deviation of...

Abstract

The invention discloses a damping fixing structure for a suspended cooling metal pipe of an articulated dump truck. A three-way metal pipe and mounting feet are arranged on a water pump, and the waterpump is fixed on a machine frame through the mounting feet; one path of the three-way metal pipe is connected with a radiator through a second rubber pipe, the other path of the three-way metal pipeis connected with one end of the suspended cooling metal pipe through a first rubber pipe, and the other end of the suspended cooling metal pipe is connected with a third rubber pipe which is fixed onthe machine frame. A fixed support comprises an upper mounting plane, a middle bent part and a lower mounting plane, and the fixed support is fixed on the machine frame through the lower mounting plane and supports and fixes the suspended cooling metal pipe through the upper mounting plane. Due to the fact that the metal pipe and the rubber pipes are connected in a staggered mode mutually, the problems of heat dissipation, rigidity and vibration resistance of a cooling pipeline are solved; and the fixed support is arranged and is consistent with the rubber pipes at the two ends of the suspended cooling pipeline in fixing source (the vibration frequency is the same), the position of the fixed support can be adjusted in the longitudinal direction and the horizontal direction, the problem offixation is solved, the cost is low, and the practicability is high.

Description

Technical field [0001] The invention relates to an articulated dump truck suspended cooling metal pipe damping fixed structure, belonging to the technical field of articulated dump trucks. Background technique [0002] Hanging cooling metal pipes have been widely used in articulated dump trucks, and the natural frequencies of the radiators and frames associated with them are quite different. At the same time, the passability and flexibility of articulated dump trucks make it difficult for the vehicle to cool the metal during operation. The vibration is relatively large, if the anti-vibration and fixation are not solved well, its reliability will be seriously affected. Summary of the invention [0003] Purpose: In order to overcome the deficiencies in the prior art, the present invention provides a damping and fixing structure for a suspended cooling metal pipe of an articulated dump truck. [0004] Technical solution: In order to solve the above technical problems, the technical so...
