DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model. Embodiment 1:

The cooling pipeline 5 includes two ports, namely a cooling port and a heat dissipation port. The working device 6 is arranged on the pipeline of the cooling pipeline 5, and the heat dissipation port is connected to the pump inlet of the water pump 3 after passing through the heat sink 4 and the water tank 2 in turn. The cooling port is connected to the pump outlet of the water pump 3. This arrangement allows the cooling pipeline 5 to absorb heat after passing through the working device 6 (the working device 6 is dissipated and cooled, which is convenient for normal operation), and the coolant after absorbing heat enters the heat sink 4 along the heat dissipation port for cooling and heat dissipation, and the cooled coolant flows back to the water tank 2 for storage. The water pump 3 pumps the coolant in the water tank 2 out to the working device 6, and then dissipates the heat of the working device 6, and the cycle is repeated to ensure that the working device 6 continues to dissipate heat. When the system is set, the height of the water tank 2 needs to be set higher than the height of the working device 6, and the height of the water pump 3 is set relatively lower than the height of the working device 6. This setting is to prevent the water pressure flowing out of the working device 6 after absorbing heat from being higher than the water pressure of the water tank 2 on the water pump 3, causing the water pump 3 to fail.

[0029] The working device 6 is equipped with a temperature sensor, and the control module 1 is electrically connected to the temperature sensor, the heat sink 4 and the water pump 3, respectively, for detecting the temperature of the working device 6 through the temperature sensor, and controlling the switch, flow rate and discharge volume of the heat sink 4 and the water pump 3. Figure 2 The water tank 2 includes a tank body and an anti-backflow pipe. The anti-backflow pipe includes a pipe body 7, a connection seat 8 and a breathable cap 9. The connection seat 8 is installed at the bottom of the pipe body 7 and is used to fix the connection and be connected to the top of the water tank 2. The breathable cap 9 is connected and installed at the top of the pipe body 7 and is used to balance the water pressure in the water tank 2 and the cooling pipeline 5. The breathable cap 9 is an existing component and its function has a pressure of 0.2 bar.

[0030] Optionally, the box body is also provided with a cleaning window, a water inlet and a liquid level gauge. Figure 2The box body includes side panels 11, an upper cover 12 and a lower cover 13. The side panels 11 are connected to each other. The upper end of each side panel 11 is closed by the upper cover 12, and the lower end is closed by the lower cover 13. A plurality of second ribs 14 are arranged between the upper cover 12 and the lower cover 13. The purpose is to make the water tank 2 have a certain stability and avoid excessive water pressure in the water tank 2, which affects the service life of the water tank 2. In addition, if Figure 3 A plurality of support plates are installed at the bottom of the box body to strengthen the force effect of the lower cover plate 13.

[0031] Optionally, the heat dissipation device 4 is a radiator. A plurality of radiators are used in the circulating cooling system of the present application. The plurality of radiators are sequentially connected in series on the cooling pipeline 5 on one side of the heat dissipation port.

[0032] Optionally, the working device 6 includes a plurality of motors, each of which is provided with a temperature sensor, which is electrically connected to the control module 1 respectively, and the corresponding cooling pipeline 5 cools and dissipates heat for any motor.

[0033] Optionally, a plurality of first ribs 10 are installed at intervals between the tube body 7 and the connecting seat 8 in the backflow prevention tube to improve the stability of the connection of the tube body 7 to the water tank 2 . Embodiment 2:

[0034] Combination Figure 4 This embodiment provides a vertical milling mining machine 15, including a car body 16, a tool holder 20, a main engine goose head 17, a reel 18 and any of the circulating cooling systems provided in the first embodiment. The structure of the vertical milling mining machine 15 is a prior art means, and a brief description is given in this embodiment to facilitate understanding of the technical effect. The installation of the vertical milling mining machine 15 is as follows: the main engine goose head 17 is movably connected to the front end of the car body 16 through an arm 21, and a cylinder 22 is provided on the car body 16, and the cylinder 22 drives the main engine goose head 17 to move closer to or away from the car body. A hoisting mechanism 23 is installed on the car body 16, and the tool holder 20 is suspended below the main engine goose head 17 through a steel rope 24 of the hoisting mechanism 23, and the hoisting mechanism 23 controls the steel rope 24 to lift and lower the tool holder 20. The working device 6 is installed in the tool holder 20, and is used to drive the milling wheel on the tool holder 20 to mill the mineral.

[0035] The control module 1, the heat dissipation device 4, the water pump 3 and the water tank 2 are all installed on the vehicle body 16 according to the installation requirements provided in the first embodiment. A reel 18 for winding and releasing the hydraulic pipeline 19 is provided at the rear end of the vehicle body 16. One end of the hydraulic pipeline 19 is connected to the vehicle body 16, and the other end enters the tool holder 20 through the reel 18 and the main engine goose head 17, and is connected to the working device 6 to drive the working device 6 to operate so that the milling wheel mills the mineral. The heat dissipation port and the cooling port of the cooling pipeline 5 provided on the working device 6 are respectively connected to the pump inlet and the pump outlet (according to the assembly sequence provided in the first embodiment) along the hydraulic pipeline 19. The position of the water tank 2 mentioned in the first embodiment is set at a position higher than the working device 6. In this setting, the position of the water tank 2 needs to be higher than the height position of the main engine goose head 17, which can produce the same technical effect as the first embodiment and avoid failure of the water pump 3 during operation.

[0036] In the present application, the vertical milling mining machine 15 uses the above-mentioned circulating cooling system to obtain the same technical effect as in Example 1. In addition, the circulating cooling system enables modular assembly with the vertical milling mining machine 15.

Part of the external cooling pipeline 5 is stored in the reel 18, and enters the tool holder 20 along the hydraulic pipeline 19 to act on the working device 6. When the tool holder 20 is raised or lowered by the steel rope 24 of the hoisting mechanism 23, the cooling pipeline 5 is acted on by the reel 18 and automatically cooperates with the retraction and release. This arrangement enables the circulating cooling system to be orderly arranged on the vertical milling mining machine 15 to avoid damage caused by unfavorable placement of the cooling pipeline.
