Angle-adjustable two-way sliding type drill boom device

Abstract

The invention belongs to the technical field of coal mine underground development equipment, and particularly relates to an angle-adjustable two-way sliding type drill boom device. According to the technical scheme, the angle-adjustable two-way sliding type drill boom device consists of a sliding seat assembly, a transmission device and a sliding assembly; the bottom end of the transmission deviceis nested on the sliding seat assembly, and the transmission device slides back and forth along a sliding rail along with the sliding seat; and the sliding assembly is nested on the transmission device and slides up and down along the transmission device. The angle-adjustable two-way sliding type drill boom device is compact in structure and good in coordination. A sliding telescopic oil cylinderstretches out and draws back to drive the transmission device to move front and back along the sliding rail, a two-way oil cylinder stretches out and draws back to drive the sliding assembly to slideup and down along a sliding frame of the transmission device, and by being matched with 180-degree rotating of a swing oil cylinder and left-right small angle adjusting of an octave oil cylinder, thedrill boom device can quickly realize the positioning construction operation of top-slope anchor rod and anchor cable holes in different positions and at various angles; and the double-stroke amplification function is achieved when an onboard jumbolter moves up and down through a chain transmission device, double-row heavy plate-type chains are adopted as the chain form, the chains are tightly connected, and a large load can be borne.

Description

technical field [0001] The invention belongs to the technical field of underground development equipment in coal mines, and in particular relates to an angle-adjustable bidirectional sliding drilling arm device. Background technique [0002] At present, domestic coal mines often use pneumatic rock bolt rigs for support operations, which are easy to operate and flexible in positioning anchor bolts and cable holes, but the safety factor is low and the drilling operation takes too long. However, when the hydraulic rock bolt drilling rig is used to drill the roof and side anchor rod and anchor cable holes, the drilling rig has a strong ability to adapt to the roadway, and the drilling operation takes a short time, but the drilling arm mechanism is too complicated, and the operation is cumbersome, and the positioning is time-consuming. Too long, poor positioning accuracy, resulting in low efficiency of the entire drilling operation, affecting the construction progress of the unde...
