Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic anchor drill devices, and in particular relates to a retractable pneumatic anchor drill auxiliary support device for mining. Background Art

[0002] Pneumatic anchor drills are a commonly used type of anchor support equipment for coal mine tunnels. They primarily anchor and support the surrounding rock by drilling, mixing, and installing anchor bolts and cables in coal and rock strata. Traditional pneumatic anchor drills rely on human operators to support the drill. Due to the complex working environment underground in coal mines, the uneven tunnel floor, and the large variations in rock hardness, the supports can tilt or even topple during operation. This not only affects work efficiency but also poses a high risk of safety accidents. Current solutions typically involve adding a drill rig anti-topple base or installing a fixed auxiliary support mechanism. Given that simply adding a base cannot fundamentally resolve the drill rig's instability, and that fixed auxiliary support mechanisms limit the height at which the pneumatic drill legs can be raised or lowered, a need arose for a retractable auxiliary support device for pneumatic anchor drills in mines. This would improve the stability of the pneumatic anchor drill during operation, safeguarding the operator's safety while also enabling the support to be retracted and quickly installed and removed, improving work efficiency.

[0006] Preferably, the detachable connecting ring is mounted on the pneumatic leg of the pneumatic anchor drill by two semicircular clamps through bolts, and one connecting block is provided at every 120° angle on the outside of the detachable connecting ring.

[0007] Preferably, a circular hole is formed at the end of the connecting block, in which a first rotating shaft is installed.
