Technical Field

[0002] During the construction of civil engineering foundation piles, earthwork excavation and material handling are required. These processes inevitably require relevant equipment, such as excavators, for excavating earthwork and handling materials.

[0003] Excavators are used in foundation pile construction for excavating earth and transporting materials. The excavator's engine and hydraulic system generate heat during operation, so an air-cooling system is needed to maintain normal operating temperature.

[0004] The air-cooled radiator consists of a fan, a medium bend, and heat dissipation fins attached to the medium bend. Through the dual heat dissipation of heat dissipation fins and air cooling, the circulating oil circuit inside the medium bend is cooled, ensuring that the oil temperature in the hydraulic system drops steadily.

One such shortcoming is the lack of convenient disassembly and assembly mechanisms, which makes disassembly and replacement inconvenient. Therefore, an air-cooled radiator is proposed to solve the existing problems. Utility Model Content

[0023] Furthermore, to facilitate the assembly and disassembly of the pressure plate 2, a positioning and engaging mechanism 7 is provided on the surface of the U-shaped frame 1. The positioning and engaging mechanism 7 includes a positioning through groove 701. There are two positioning through grooves 701, which are respectively located on the front and rear sides of the inner cavity of the pressure plate 2. Sleeves 702 are fixedly connected to the front and rear sides of both sides of the U-shaped frame 1. A positioning pin 703 is slidably connected inside the sleeve 702. One end of the positioning pin 703 passes through the U-shaped frame 1 and extends into the interior of the positioning through groove 701.

A pull rod 706 is rotatably arranged between the two mounting plates 705 on the same side.

[0024] Furthermore, to facilitate the simultaneous release of the limiting fit between the heat dissipation fins 6 and the heat exchange bend 3 and between the pressure plate 2 and the heat exchange bend 3, the surface of the U-shaped frame 1 is provided with a linkage drive mechanism 8 that is used in conjunction with the central control mechanism 5 and the positioning and locking mechanism 7. The linkage drive mechanism 8 includes a threaded adjustment rod 801. There are two threaded adjustment rods 801, and the two threaded adjustment rods 801 are respectively rotatably set on both sides of the U-shaped frame 1.

[0025] The advantages of Example 2 compared to Example 1 are reflected in the following: by setting up the linkage drive mechanism 8, the linkage drive mechanism 8 can drive the central control mechanism 5 and the positioning and locking mechanism 7 simultaneously, so that the vertical and horizontal limits of the heat exchange bend 3 can be released simultaneously, further improving the efficiency of convenient disassembly and assembly.

[0026] During use, the overheated cooling oil circulates from inside the equipment to the external heat exchange bend 3 for circulation. During the circulation process, the heat is transferred to the heat dissipation fins 6 and then returned to the inside of the equipment after cooling down. During the indirect heat dissipation process, the drive motor 403 is started. The drive motor 403 drives the rotating shaft 404 and the fan blades 405 to rotate, thereby dissipating heat from the heat dissipation fins 6 and the heat exchange bend 3 by airflow. When disassembling and replacing the heat exchanger bend 3, disconnect the end of the heat exchanger bend 3 from the equipment oil circuit beforehand. Then rotate the threaded adjusting rod 801. The threaded adjusting rod 801 rotates the threaded sleeve 802 on its surface, which drives the control plate 508 to descend through the horizontal plate 803. The descending control plate 508 pushes the connecting rod 509 to unfold. The unfolding connecting rod 509 pushes the sliding column 502 and the heat dissipation fins 6 to move. The movement of the heat dissipation fins 6 will disengage from the limiting contact of the heat exchanger bend 3. As the threaded sleeve 802 descends, it simultaneously drives the inclined rod 804 to descend as well. The inclined surface of the descending inclined rod 804 will press against the pull rod 706, causing the pull rod 706 to pull the mounting plate 705 to move laterally. The lateral movement of the mounting plate 705 will pull the positioning pin 703 back into the sleeve 702. After the positioning pin 703 retracts into the sleeve 702, it will disengage from the positioning slot 701. Then, the handle is grabbed to lift the pressure plate 2, causing the pressure plate 2 to disengage from the vertical limit on the heat exchanger bend 3.
