Description

Technical Field

[0001] The invention relates to the technical field of downhole drilling rigs, and in particular to a monorail hydraulic rock drilling rig. Background Art

[0002] The rock drilling rig is an essential machine for underground rock drilling and drilling. It is mainly used for blasting drilling in hard rock tunnels and tunnel roof support anchor drilling. It is widely used. At present, rubber-wheeled and crawler rock drilling rigs are mainly used underground. The whole machine is large in size, suitable for a narrow range of tunnel sizes, and has a high cost. During the blasting construction process, the equipment and personnel need to be evacuated after the drilling is completed, which seriously affects the progress of the construction. In addition, when the rock drilling rig retreats and returns to its position to continue working, the drilling hole needs to be repositioned, which greatly increases the construction time of the entire tunnel.

[0003] When drilling blastholes on the tunnel blasting working face, the rock drill needs to drill slot holes, auxiliary holes, peripheral holes and bottom holes in different positions. Since the body of the rock drill cannot deviate from the center of the tunnel, high requirements are placed on the mechanical arm of the rock drill at this time. The existing mechanical arms do not have the characteristics of multiple degrees of freedom, flexibility and accuracy. Summary of the invention

[0004] In order to facilitate the rock drilling rig to drill groove holes, auxiliary holes, peripheral holes and bottom holes in different positions, the present application proposes a monorail crane hydraulic rock drilling rig, which can not only be towed by the monorail crane, but also directly connected to other equipment to be transported on the monorail crane, which can solve the problem of upper space utilization underground, reduce tunnel construction time and improve construction efficiency.

[0015] 1. The hydraulic rock drill and the monorail crane are organically combined, which can not only improve the utilization rate of underground space, but also effectively increase the speed of tunnel construction;

[0016] 2. In the past, after the impact drilling operation was completed, the drilling equipment and personnel had to be withdrawn, and the excavation equipment and other equipment had to be driven into the working face for construction, which made the process too complicated. The hydraulic rock drill rig designed was installed on a monorail crane, and the track of the monorail crane was hung on the top of the tunnel, which could leave sufficient space for the excavation equipment to carry out construction operations;

[0017] 3. The designed monorail crane uses batteries as the power source, which realizes environmental protection and energy saving. The battery-driven hydraulic pump station replaces the previous larger motor as the driving device, which improves the driving torque of the whole machine while reducing the size and weight of the whole machine. The requirements for the track and anchor cable hanging on the top of the tunnel are further reduced, reducing the fixed installation cost of the whole set of equipment;

[0018] 4. The monorail crane is equipped with a support and guide device. When the whole machine encounters special working conditions such as bends during operation, the speed requirement of the whole machine will not be particularly harsh. It can effectively assist in steering and reduce friction resistance. The support and guide devices are arranged in pairs in the monorail crane, which can effectively improve the stability of the whole machine during operation;

[0019] 5. During the tunnel drilling construction process, the hydraulic rock drill system is fixed on the support guide device, and the fixed seat is always located on the center line of the track, so the working space of the entire hydraulic rock drill system is wider; the hydraulic rock drill system has multiple adjustment cylinders, which can realize construction drilling operations in multiple postures.
