A bracket for a rock drill

Abstract

The invention discloses a bracket of a rock drilling machine. A base of the bracket comprises an upper base plate, a lower base plate, four truss rods and a connecting rod, the lower base plate is positioned below the upper base plate, the four truss rods are arranged between the upper base plate and the lower base plate and are mounted in a staggered manner, and the connecting rod is arranged in the middles of the four truss rods; a mounting seat is positioned on the upper portion of the base and comprises movement tracks, a motor, a motor plate, a rack, two cylinders and rock drilling machine bases, the motor plate is mounted above the movement tracks, the motor is mounted in the middle of the motor plate, a gear is arranged at a lower output end of the motor and meshes with the rack, the two cylinders are mounted at two ends of the upper side of the motor plate, and piston rod ends of the cylinders are connected with the rock drilling machine bases. The bracket has the advantages that the two cylinders are arranged on the motor plate, so that the height of the rock drilling machine can be finely adjusted, the bracket is convenient and practical, and obvious enhancement effects can be realized for working conditions with high requirements on position precision.

Description

Technical field: [0001] The invention relates to the technical field of rock crushing machinery, in particular to a bracket of a rock drilling machine. Background technique: [0002] At present, the rock drilling machine used for tunnel excavation is completely operated manually, which has low efficiency, high labor intensity, and low safety. For this problem, the invention application number is 201020202432.8 The rock drilling machine bracket specially used for tunnel excavation introduces a bracket , including lift track, lift frame, rock drilling machine platform, rock drilling machine track; the bottom of the lifting frame can roll or slide on the track, the rock drilling machine platform is installed above the elevator, and there is a rock drilling machine track on the upper surface of the rock drilling machine platform; the rock drilling machine The supporting platform includes a lower supporting plate, an upper supporting plate, and a bearing between the upper and low...

[0002] At present, the rock drilling machine used for tunnel excavation is completely operated manually, which has low efficiency, high labor intensity, and low safety. For this problem, the invention application number is 201020202432.8 The rock drilling machine bracket specially used for tunnel excavation introduces a bracket , including lift track, lift frame, rock drilling machine platform, rock drilling machine track; the bottom of the lifting frame can roll or slide on the track, the rock drilling machine platform is installed above the elevator, and there is a rock drilling machine track on the upper surface of the rock drilling machine platform; the rock drilling machine The pallet includes a lower pallet, an upper pallet, and a bearing between the upper and lower pallets; the upper end of the bearing is fixedly connected to the upper pallet, and the lower end of the bearing is fixedly connected to the lower pallet to realize the relative rotation of the upper and lower pallets

However, the design of the bracket of the present invention in terms of fine-tuning the height of the rock drill is not ideal, and there is a problem that the height of the fine-tuning is inflexible
