[0002] The shield machine has the advantages of high automation degree, labor saving, fast construction speed, one-time tunneling, not affected by climate, controllable ground settlement during excavation, reduced impact on ground buildings, and no impact on water surface traffic during underwater excavation. It is often used for tunnel construction. The shield machine tools can be basically divided into two categories: cutter bits and rolling cutters. The rolling cutters are suitable for rock breaking but have low tunneling efficiency in soft soil layers. The cutter bits are suitable for soft soil layers but are prone to excessive wear or chipping and fracture when encountering hard rock formations. For areas with complex geology, a composite cutter head is usually used, that is, cutter bits and rolling cutters exist on the same cutter head at the same time;

[0003] When the shield machine is performing tunnel tunneling operations, it often first breaks through a section of the tunnel and enters an open area, and then performs the tunneling operation of the next section of the tunnel after passing through the open area. After completing the tunneling operation of a section of the tunnel, the temperature of the cutter bits and rolling cutters on the tool often rises after a tunneling cycle, and at the same time, the temperature of the bearings and bearing sleeves on the tool also rises. When performing the tunneling operation of the next section of the tunnel, it is necessary to cool down the cutter bits and rolling cutters on the tool and the bearings and bearing sleeves on the tool.

It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0039] In the embodiment, it is given by Figure 1-7 A shield machine cutter spraying and cooling system, wherein, Figure 1 This is a schematic structural view of the overall shield machine cutter spraying and cooling system of the present utility model; Figure 2 This is a schematic structural view of the shield machine cutter spraying and cooling system when viewed from another angle of the present utility model; Figure 3Explosion diagram of the cutter spray cooling system of the shield machine of the present utility model; Figure 4 Structural schematic diagram of the present utility model when the built-in filter sleeve and the external filter sleeve are combined; Figure 5 Structural schematic diagram of the overall rotating support member of the present utility model; Figure 6 Structural schematic diagram of the overall spray member of the present utility model; Figure 7 It is a signal transmission diagram between the temperature sensor and the receiver, as well as between the solenoid valve and the drive motor of the present utility model. It includes a rotating support member 1, on which a chassis 2 is detachably arranged, and it can drive the chassis 2 to perform a rotating operation; a top plate 21, which is located on one side of the chassis 2, and a built-in filter sleeve 22 is detachably arranged on it, and the built-in filter sleeve 22 is connected to the chassis 2, and there is a columnar area inside the built-in filter sleeve 22; an external filter sleeve 23, which is detachably arranged on the top plate 21, and it is connected to the chassis 2, and it covers the built-in filter sleeve 22 inside it; a temperature sensor 24, which is detachably installed on the top plate 21, and one end of it can penetrate into the columnar area of the built-in filter sleeve 22; a ball bearing 25 for plugging into one end of the shield machine, which is detachably installed on the top plate 21; and two groups of spray members 3, both of which are detachably arranged on the rotating support member 1, and both groups of spray members 3 are located in the columnar area of the built-in filter sleeve 22, and the spray member 3 is used for spraying and cooling the shield machine cutter penetrating into the columnar area.

[0040] An overall idea of the present utility model is that through the arranged top plate 21 and ball bearing 25, one end of the shield machine cutter can pass through the ball bearing 25 and penetrate into the columnar area of the built-in filter sleeve 22. The temperature sensor 24 can monitor the temperature in the columnar area in real time. After reaching the predetermined temperature threshold of the temperature sensor 24, it sends a signal to the receiver 19, and the receiver 19 simultaneously sends a signal to the drive motor 12 and the solenoid valve 32, so that the drive motor 12 drives the driving wheel 13 to rotate, to drive the overall rotating disk 17 to rotate, and at the same time, the coolant is sprayed from the spray plate 33 and the atomizing nozzle 34 into the shield machine cutter, and can perform a rotating spray cooling operation. The sprayed coolant flows out from the built-in filter sleeve 22 and the external filter sleeve 23 in sequence.

[0041] After the shield machine has completed tunneling a section of the tunnel and entered an open area, it means that before the tunneling work of the next section of the tunnel, after completing the tunneling operation of a section of the tunnel, at this time, 25 ball bearings in this spray cooling system can be sleeved onto the cutter head of the shield machine, and at the same time, the connection between the overall rotating support member 1 and the ground can be strengthened, so that this spray cooling system can operate stably. After the spraying member 3 operates, the cutter head of the shield machine can be sprayed and cooled, and at the same time, the bearings and bearing sleeves on the cutter head of the shield machine can be sprayed and cooled, so as to extend the service life of the bearings and bearing sleeves on the cutter and cutter head of the shield machine;

[0042] It should also be noted that the temperature sensor 24 is a known component in the prior art, and the temperature sensor 24 can set three or more groups of values. When the cutter of the shield machine reaches the first group of values, the temperature sensor 24 transmits a signal to the receiver 19, and the receiver 19 transmits a signal to the solenoid valve 32, so that the solenoid valve 32 releases the coolant. It should be noted that the solenoid valve 32 is also a known component in the prior art, and the opening and closing of the solenoid valve 32 can be adjusted;

[0043] When the temperature sensor 24 reaches the second value, at the same time, the temperature sensor 24 transmits a signal to the solenoid valve 32 again, so that the solenoid valve 32 increases the amount of coolant discharged;

[0044] When the temperature sensor 24 reaches the third value, at the same time, the temperature sensor 24 transmits a signal to the solenoid valve 32 again, so that the solenoid valve 32 further increases the amount of coolant discharged to achieve the effect of cooling spray;

[0045] It should also be noted that the set values reached by the temperature sensor 24 can be other quantities, and the first, second, and third values increase in sequence, and the first, second, and third values can be formulated according to the actual use situation. In this embodiment, no excessive restrictions and elaborations are made.

[0046] Next, a more specific structure and configuration are given to the entire rotating support member 1 for further explanation. The rotating support member 1 includes a support base 11, on which a driving motor 12 is detachably arranged, and the output end of the driving motor 12 can penetrate into the support base 11. A driving wheel 13 is detachably arranged on the output end of the driving motor 12, and a belt 14 is removably sleeved on the driving wheel 13; a turbine reducer 15, which is detachably arranged on the support base 11, a driven wheel 16 is detachably arranged on one of its output ends, and the driven wheel 16 is bypassed by the belt 14. A rotating disk 17 is detachably arranged on the other output end, and the rotating disk 17 is detachably connected to the chassis 2; a control panel 18, which is detachably arranged on the support base 11 and is electrically connected to the driving motor 12; and a receiver 19, which is detachably arranged on the support base 11, is signal-connected to the temperature sensor 24, and is signal-connected to the driving motor 12;

[0047] Next, the operating principle of the entire rotating support member 1 is further explained. After the receiver 19 receives the signal that the temperature sensor 24 reaches the predetermined temperature, it transmits the signal to the driving motor 12, so that the driving motor 12 drives the driving wheel 13 to rotate, drives the turbine reducer 15 and the rotating disk 17 to rotate, and can drive the two spray members 3 to perform rotary spraying and cooling operations.

[0048] In some embodiments, in order to improve the tension and stability of the belt 14 during use, the size of the driving wheel 13 is the same as the size of the driven wheel 16, and the belt 14 is tensioned on the driving wheel 13 and the driven wheel 16.

[0049] In some embodiments, in order to facilitate the release of the spray liquid during the rotary spraying process when the external filter sleeve 23 rotates, a plurality of diamond-shaped barrel grooves are also formed on the external filter sleeve 23, and every two diamond-shaped barrel grooves are in contact with each other. The size of the diamond-shaped barrel grooves is adapted to the size of the external filter sleeve 23.

[0050] In some embodiments, in order to facilitate the release of the spray liquid during the rotary spraying process when the internal filter sleeve 22 rotates, a plurality of vertical barrel grooves are also formed on the internal filter sleeve 22, and every two vertical barrel grooves are in contact with each other. The size of the vertical barrel grooves is adapted to the size of the internal filter sleeve 22.

[0051] In some embodiments, in order to facilitate the quick connection between the rotating disk 17 and the spray member 3, two jack holes are also formed on the rotating disk 17, and the size of the two jack holes is adapted to the size of the rotating disk 17.

[0052] Next, a more specific structure and configuration are given to the overall spray member 3 for further explanation. The spray member 3 includes a watering can 31 with a pin at its bottom, and the pin can penetrate into the jack; an electronic valve 32 detachably arranged at the outlet end of the watering can 31 and signal-connected to the receiver 19; and a spray plate 33 detachably arranged at one end of the electronic valve 32, on which multiple groups of atomizing nozzles 34 are detachably arranged, and the sizes of the multiple groups of atomizing nozzles 34 are adapted to the size of the spray plate 33.

[0053] Next, the working principle of the overall spray member 3 is further explained. After the electronic valve 32 receives the release signal, the electronic valve 32 releases the spray liquid into the spray plate 33 and the atomizing nozzles 34 to complete the spray cooling operation of the shield machine cutter.

[0054] It should also be noted that the signal transmission principle between the receiver 19, the drive motor 12 and the electronic valve 32 is a known principle in the prior art, so it will not be elaborated too much in this case.

[0055] In some embodiments, in order to improve the stability of the pin of the watering can 31 when it penetrates into the jack, a rubber sleeve is detachably installed on the pin of the watering can 31, and the size of the rubber sleeve is adapted to the size of the pin of the watering can 31.

[0056] In summary, through the arranged top plate 21 and ball bearing 25, one end of the shield machine cutter can pass through the ball bearing 25 and penetrate into the cylindrical area of the built-in filter sleeve 22. The temperature sensor 24 can monitor the temperature in the cylindrical area in real time. After reaching the predetermined temperature threshold of the temperature sensor 24, a signal is sent to the receiver 19, and the receiver 19 simultaneously sends signals to the drive motor 12 and the electronic valve 32, so that the drive motor 12 drives the driving wheel 13 to rotate, driving the overall rotation of the rotating disc 17. At the same time, the coolant is sprayed from the spray plate 33 and the atomizing nozzles 34 into the shield machine cutter, and a rotating spray cooling operation can be performed. The sprayed coolant flows out from the built-in filter sleeve 22 and the external filter sleeve 23 in sequence.

[0057] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
