Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a rotary drilling rig. Background Art

[0002] At present, most of the rotary drilling rigs in the engineering industry are dominated by traditional fuel vehicles. However, as the country's requirements for engineering environmental protection become higher and higher, new energy rotary drilling rigs (hybrid rotary drilling rigs or pure electric rotary drilling rigs) will surely become the trend of future development. The counterweights of traditional fuel rotary drilling rigs are all at the tail of the whole machine. Hybrid or pure electric rotary drilling rigs need to add batteries as a power source. Considering the layout of the whole machine, the battery needs to be placed at the tail of the whole machine. The turntable of the traditional fuel rotary drilling rig is reserved with a counterweight installation plane, but there is no space for placing the battery assembly. Existing hybrid or pure electric rotary drilling rigs usually install the counterweight and battery assembly at the tail of the whole machine by bolts. Due to the harsh working environment of the rotary drilling rig, it will produce severe vibrations during work. Under long-term working conditions, the bolts are prone to loosening. Loose bolts cause the counterweight connection to be unstable and the battery assembly will also shake. This situation is very dangerous and affects the safety of the hybrid rotary drilling rig. Therefore, how to save the installation space of the battery assembly while ensuring the stability and safety of the battery assembly connection is a problem that technicians in this field need to solve.

When the two upper and lower surfaces relatively arranged between the turntable frame 10 and the first counterweight portion 211 tend to be displaced, the anti-shear member 31 can withstand lateral shear force to prevent the fastener 32 from breaking due to the large shear force.

[0035] Similarly, the second counterweight part 212 is provided with a second mounting hole, and the second protrusion 15 of the turntable frame 10 is provided with a second through hole.
