Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology for rock drilling rigs, and more specifically to an air conditioning compressor drive device for rock drilling rigs. Background Technology

[0002] Rock drilling rigs are mainly used in mining operations, where the working environment is relatively harsh, especially in summer. The cab is a relatively enclosed and cramped space with high internal temperatures, thus requiring air conditioning for cooling. Currently, the air conditioning in rock drilling rigs is mainly powered by an electric motor-driven compressor. However, the battery capacity of the rig is limited and cannot meet the power requirements of the air conditioning motor. Therefore, the air conditioning motor is powered by an external power source, which is the mains power supplied from the mine's electrical grid. This power supply method has the following problems: (1) Since the air conditioner needs to be connected to the mains plug, although the power cord is long enough to allow the rock drilling rig to move within a certain range inside the mine, the power cord will inevitably become loose due to dragging during operation, which will affect the stability of the air conditioner operation. (2) When the rock drilling rig is used for relocation operations, it is necessary to drive the rig for long-distance road travel. At this time, it is not possible to continue to use the mains power supply. The capacity of the rig's own battery is also limited and cannot meet the conditions for long-distance air conditioning operation. Utility Model Content

A drive pulley 8 is mounted on the output shaft of the hydraulic motor 4. The drive pulley 8 is engaged with a driven pulley 10 on the output shaft of the air conditioning compressor 9 via a belt. A cooling fan 14 is fixedly mounted on the side of the mounting frame 1. This drive unit, utilizing the rock drilling rig's own hydraulic system, provides power to the air conditioning compressor, ensuring normal operation of the air conditioning under all working conditions, maintaining the operating temperature of the cab, and enhancing the flexibility of use. In actual operation, the entire air conditioning compressor drive unit is fixedly installed on the rock drilling rig, and the hydraulic motor 4 is connected to the hydraulic system of the corresponding rock drilling rig to provide hydraulic power. The hydraulic motor 4 drives the drive pulley 8, and the drive pulley 8 and the driven pulley 10 mesh to drive the air conditioning compressor 9. In turn, the air conditioning compressor 9 drives the air conditioning system to achieve the temperature regulation of the cab.

[0030] Since this drive unit directly utilizes the hydraulic power system of the rock drilling rig itself, it does not require an additional external power source. This greatly increases its adaptability and flexibility. During actual operation or long-distance relocation, it will not be limited by the power supply, and it can adjust the temperature of the cab at any time, thus improving the driving environment of the rock drilling rig.
