Description

Technical Field

[0001] The present invention belongs to the technical field of coal mine development machinery, and specifically relates to a rope wheel stroke amplifying airborne drilling rig used for drilling holes, anchor cables and anchor rods in rock tunnels, coal tunnels and semi-coal-rock anchor rod support construction in coal mines, as well as for constructing various blast holes, anti-burst holes and water exploration holes. Background Art

[0002] At present, in the field of mechanized drilling construction operations in coal mines, manual pneumatic drilling rigs are used for drilling support, or domestic single-function and foreign large-sized airborne drilling rigs are used. Manual pneumatic drilling rigs have high labor intensity and pose great safety hazards; domestic airborne drilling rigs have single functions and do not have the functions of drilling, positioning and disassembling drill rods. Manual disassembly of drill rods poses safety hazards; foreign airborne drilling rigs are large in size and have low adaptability due to the limitations of the underground tunnel cross-section, which seriously affects the excavation progress.

[0003] The propulsion mechanism currently used by airborne drilling rigs uses one or two-stage propulsion cylinders to achieve the propulsion stroke required for construction. First, there are many cylinders, and each stage of propulsion requires the extension and contraction of the cylinders to achieve a certain propulsion stroke. Due to the limitation of the cylinder structure, it is difficult to achieve a larger stroke through the cylinders. If the propulsion stroke required for underground construction is achieved simply by increasing the number of cylinders, the airborne drilling rig will be larger in size and not suitable for complex underground working conditions. In actual operation, the larger airborne drilling rig structure not only requires a larger power system, but also affects the sight of the construction workers, causing safety hazards, and often causes misoperation and damage to the airborne drilling rig. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies in the above-mentioned prior art and to provide an airborne drilling rig with a rope pulley stroke amplification.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a rope sheave stroke amplifying airborne drilling rig, which includes a slideway bottom plate, a positioning cylinder, a connecting plate, a clamping cylinder, a thrust cylinder, a rope sheave assembly I, a rope sheave assembly II, a primary slide rail, a rope sheave assembly III, a rope sheave assembly IV, a secondary slide rail, a sliding seat, and an impact rotary drill; the positioning cylinder is installed at the front end of the primary slide rail, and the lower end of the connecting plate is installed on the piston rod of the positioning cylinder; the clamping cylinder is installed at the upper end of the connecting plate, and the required oil channel connected to the clamping cylinder is provided inside the connecting plate and the positioning cylinder; the primary slide rail is installed on the top of the slideway bottom plate, and one end of the thrust cylinder is fixed on the slideway bottom plate , and the other end is hinged on the primary slide rail; the secondary slide rail is installed on the top of the primary slide rail, one end of the rope pulley assembly I is connected to the rear end of the slide base plate, and the other end is wrapped around the primary slide rail and connected to the secondary slide rail; one end of the rope pulley assembly II is connected to the front end of the slide base plate, and the other end is wrapped around the front end of the secondary slide rail and connected to the rear end of the secondary slide rail; the sliding seat is installed on the secondary slide rail, one end of the rope pulley assembly III is connected to the front end of the primary slide rail, and the other end is wrapped around the secondary slide rail and connected to the rear end of the sliding seat, one end of the rope pulley assembly IV is connected to the primary slide rail, and the other end bypasses the secondary slide rail and is connected to the front end of the sliding seat; the impact rotary drill is fixed on the sliding seat.

[0006] Compared with the prior art, the present invention has the following advantages:

[0007] First, only one set of propulsion cylinders is needed, and reducing the number of cylinders reduces the limitations of the cylinder mechanism, thereby minimizing the size of the airborne drilling rig and increasing the flexibility of the operation.

[0008] Second, due to the small number of active parts, simple structure, low failure rate and quick troubleshooting, the reliability and safety of the mechanism are relatively improved.

[0009] Thirdly, the drilling positioning of the present invention is highly stable. Since the positioning cylinder and the clamp are added at the front end, the clamp is convenient for the disassembly and installation of the drill rod. The positioning cylinder can accurately position the drill rod on the one hand and reduce the shaking of the drill rod during the drilling construction on the other hand, thereby ensuring the stability of the drilling construction. The mutual cooperation between the positioning cylinder and the clamp greatly reduces the labor intensity, improves the work efficiency, indirectly ensures the safety of the workers' operation, and enables the airborne drilling rig to operate safely, stably and efficiently.

[0010] Fourthly, oil passages are arranged inside the connecting plate and the positioning cylinder to connect the clamping cylinder, thereby realizing the integration of the oil passages, simplifying the pipelines, saving space and improving the reliability of the airborne drilling rig.
