Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil filling devices, and more specifically, to a lubricating oil filling device for an integrated excavator and anchor machine. Background Technology

[0002] When the tunneling and anchoring machine is working, the friction between its various parts will cause the lubricating oil temperature to rise. If the oil tank does not dissipate heat, the excessively high oil temperature will cause the lubricating oil viscosity to decrease, affecting the lubrication effect and increasing the wear of the parts. In order to facilitate the dissipation of heat from the oil tank, heat dissipation fins are usually designed on the surface of the oil tank. By increasing the contact area between the oil tank and the air, the heat is carried away by the natural convection of the air.

[0003] However, by installing heat dissipation fins on the outer wall of the oil tank, the heat dissipation fins can only directly cool the lubricating oil near the inner wall of the oil tank. The lubricating oil in the middle of the oil tank is far from the heat dissipation surface and has difficulty exchanging heat with the air, resulting in poor cooling effect. Utility Model Content

The outer wall of the external heat dissipation pipe is inserted into the oil filling tank of the tunneling and anchoring machine, which can directly dissipate heat from the lubricating oil in the middle of the tank, solving the problem of poor cooling effect of the lubricating oil in the middle of the tank and improving the overall heat dissipation efficiency of the lubricating oil.

[0009] The air guide assembly includes two conical air guide covers, which are fixedly connected to both ends of the external heat dissipation pipe. The conical air guide covers are fixedly connected to the mounting holes, and the diameter of the air guide covers increases along the airflow direction.

[0010] Preferably, the top of the oil tank of the tunneling and anchoring machine is provided with a detachable oil tank cover, and the top of the oil tank cover is symmetrically provided with lifting handles.

[0032] The conical air guide shroud 8 guides the airflow, accelerating the airflow within the outer heat dissipation pipe 7 and the inner heat dissipation pipe 9, thereby improving the heat dissipation efficiency of the first heat dissipation fin 10. Through the coaxially arranged outer heat dissipation pipe 7 and multiple first heat dissipation fins 10, the outer wall of the outer heat dissipation pipe 7 extends deep into the oil tank 1 of the tunneling and anchoring machine, directly dissipating heat from the lubricating oil in the middle of the oil tank. This solves the problem of poor cooling effect of the lubricating oil in the middle of the oil tank in the prior art, improves the overall heat dissipation efficiency of the lubricating oil, ensures the lubrication effect of each component of the tunneling and anchoring machine, and reduces wear.

[0033] In some embodiments, to improve the sealing between structures, a combination of O-rings and lip seals can be used to seal the connection between the external heat dissipation pipe 7 and the oil tank 1 of the tunneling and anchoring machine. The O-rings provide a basic seal, while the lip seals can further conform to the sealing surface under pressure to enhance the sealing effect.

[0034] In some embodiments, to improve the connection strength between structures, multiple support points can be provided in the oil storage cavity 3, and the external heat dissipation pipe 7 can be fixedly connected to the inner wall of the oil tank by brackets or tie rods to improve the connection strength.

[0035] like Figure 1 As shown, in some embodiments, the top of the oil tank 1 of the tunneling and anchoring machine is provided with a removable oil tank cover 5, and the top of the oil tank cover 5 is symmetrically provided with a lifting handle 6.

[0036] like Figure 1 As shown, in some embodiments, the outer wall of the oil tank 1 of the tunneling and anchoring machine is provided with a plurality of axially distributed second heat sinks 22.

The structural design of the fixing rod 11, retaining ring 12, cross 13 and locking nut 14 facilitates the disassembly and installation of the stepper motor 19.

[0040] In some feasible embodiments, a pulley and belt can be provided between the output end of the stepper motor 19 and the output shaft 20. The stepper motor 19 drives the pulley to rotate, and through the belt drive, the output shaft 20 rotates and drives the cooling fan 21. This method can provide a certain buffering effect, reducing the impact force when the stepper motor 19 starts and stops. Furthermore, for scenarios with high noise requirements, belt drive noise is relatively low. In addition, belt drive has a simple structure, low cost, and is relatively easy to maintain and replace.

[0041] In some other embodiments, a gear set can be used instead of a direct connection between the stepper motor 19 and the output shaft 20. A driving gear is installed at the output end of the stepper motor 19, and a driven gear is installed on the output shaft 20. Power transmission is achieved through the meshing of the gears. Gear transmission has the advantages of accurate transmission ratio, high efficiency, and compact structure.

[0042] Working principle: When the tunneling and anchoring machine is running and the lubricating oil heats up, the lubricating oil in the tunneling and anchoring machine's oil tank 1 flows around the outer heat dissipation pipe 7, and the first heat dissipation fin 10 increases the heat dissipation area; at the same time, the stepper motor 19 drives the output shaft 20 to drive the cooling fan 21 to rotate, and the airflow is introduced through the conical air guide shroud 8 whose diameter increases along the airflow direction, improving the air circulation in the outer heat dissipation pipe 7 and the inner heat dissipation pipe 9, which facilitates the heat dissipation of the first heat dissipation fin 10.
