Description

[0002] As the technology of open-pit mining matures, open-pit mining presents a thriving scene. In order to improve the mining efficiency of mineral resources and reduce operating costs, the demand for super-large hydraulic excavators of 100 tons and above is gradually expanding. In order to avoid excessive temperatures of cooling water and oil of large hydraulic excavators and to ensure that the engine and hydraulic pump can continue to work efficiently, this type of excavator needs to be equipped with multiple large radiators. Since excavators are often in harsh working conditions, a large amount of dust, dirt and other dirt are easily accumulated on the surface and inside of the radiator. If not cleaned in time, the working efficiency of the excavator will be reduced and the machine may be damaged prematurely. The existing cleaning technology is to remove the air intake grille and related parts or radiators, and then manually clean the radiator with an external high-pressure water gun. Due to the large size of the radiator, the cleaning time is long, water resources are wasted, and the cleaning effect is not good. At the same time, due to the large height difference between the installation position of the radiator and the ground, there is a risk of people falling from a high altitude during the cleaning process.

The slider 506 is controlled by the stepper motor 502 to reciprocate up and down on the ball screw 505, thereby driving the cleaning mechanism 6 to move linearly.

[0047] The above-mentioned cleaning mechanism is further described below.

[0048] like Figure 4As shown, the cleaning mechanism includes a cleaning pipe 604, a mounting valve block 603, a mounting seat 606, and a plurality of high-pressure nozzles 605; the cleaning pipe 604 spans across the monorail linear slider module assembly 5 on both sides, and is connected to the water pump assembly 2 through a conduit; the mounting valve block 603 is installed at one end of the cleaning pipe 604, and a water flow channel is provided inside the mounting valve block 603, so that water flows into the cleaning pipe 604; the mounting seat 606 is installed at the other end of the cleaning pipe 604, and the mounting valve block 603 and the mounting seat 606 are both connected to the slider 506 in the monorail linear slider module assembly 5 through fasteners 607; a plurality of high-pressure nozzles 605 are evenly and alternately arranged on the radial circumferential surface of the cleaning pipe 604 for spraying water.

[0049] A further solution: the high pressure nozzle 605 adopts a rotatable nozzle, the water jet is fan-shaped, the jet angle is 25°-110°, and adjacent jets can cover each other.

[0050] Figure 2 This is a front view of the cleaning mechanism in standby state. In the standby state, the cleaning mechanism 6 is located at the bottom of the single-track linear slider module assembly 5, and the high-pressure nozzle 605 is vertically facing downward.

[0051] Further solution: A motor 602 is also installed on the mounting valve block 603, and the rotating shaft of the motor 602 is connected to the cleaning pipe 604. The cleaning pipe 604 is rotatably supported in the mounting seat 606. The cleaning pipe 604 is driven to rotate by the rotation of the motor 602, thereby adjusting the cleaning angle between the high-pressure nozzle 605 and the radiator 4, and the adjustment range is 0-180°.

[0052] A further solution: the installation valve block 603 is threadedly installed with a water pipe joint 601, the water pipe joint 601 is connected to the internal water flow channel of the installation valve block 603, the water pipe joint 601 is connected to the water pump assembly 2 through a hose, and the water pump assembly 2 draws water from the water tank 1 through the hose to provide high-pressure water flow for the cleaning mechanism 6.

The high-pressure nozzle 605 can be adjusted from 0° (the initial position of the nozzle is vertically downward) to 180°. The radiator 4 can be cleaned from multiple angles during the cleaning process. At the same time, the incident angle of the cleaning water flow can also be adjusted to avoid damage to the heat dissipation fins of the radiator 4 and reduce the heat dissipation effect. The other side is directly connected to the water pump assembly 2 through a hose, and can also be connected to an external water source to provide high-pressure water flow.

[0057] The utility model has a simple structure and can be directly installed in the limited space between the air intake grille and the radiator. In addition, one-button automatic cleaning can be realized anytime and anywhere without removing the air intake grille and related parts, and without stopping the machine for cleaning, so as to simplify the cleaning steps, reduce the cleaning cost, and improve the cleaning efficiency.
