Description

Technical Field

[0001] The present invention relates to a bolt drill jumbo, specifically a double-arm lifting bolt drill jumbo based on a single rail, belonging to the technical field of roadway tunneling machinery. Background Art

[0002] At present, in roadway tunneling construction in coal mines or non-coal mines, etc., the tunneling machines, rock drilling jumbo, tunnel drills (drilling water exploration air holes), bolt drill jumbos, drill and loading units, etc. used are all equipment that travels on the ground with crawlers or tires. Such roadway construction equipment traveling on the ground not only occupies a certain ground space size, but also because the cross-sectional size of the roadway is relatively narrow, when these equipment need to enter the narrow roadway for construction operations, it is necessary to first withdraw the construction equipment of the previous process, and then drive the equipment of this process into the roadway and carry out the corresponding construction operations. During this process, there is a long time of "empty roof". If the geological conditions are not good and there is a large rock burst, the roadway is prone to collapse under the empty roof, and serious safety accidents may occur in severe cases. In addition, in order to ensure the safe passing of construction equipment, some mines widen the roadway, and some mines make "passing bays" at certain intervals in the roadway. Whether widening the roadway or making "passing bays", it will affect the geological structure and increase the roadway tunneling and support costs; and the frequent entry and exit of equipment in the roadway for passing will take a lot of time, and a lot of manual cooperation is required to command the backing or driving in of the vehicle, etc. Coupled with the poor lighting in the roadway, collisions are also prone to occur during the passing process. Therefore, whether it is "empty roof" or passing, there are safety hazards, and it affects the construction efficiency, resulting in a low roadway tunneling footage.

[0003] Most of the existing suspended rail drill and anchor equipment adopt wing-type arm mechanisms. When working, it is necessary to lower the drill arm platform through the wing-type arm mechanism and then erect the drill rig assembly to carry out drilling construction. There are the following problems:

[0004] 1. The drill rig assembly can only be erected to drill holes around the cross-section and cannot directly drill holes forward;

[0005] 2. The drill rig assembly cannot adjust its own position height according to the cross-section size and cannot adapt to the working conditions of higher or lower roadways;

[0006] 3. The manual service platform of the drill rig assembly is not safe, people cannot move with the drill, the operation is inconvenient, and the operation of quickly positioning and drilling multiple rows of bolts at one time cannot be carried out;

[0074] When the present invention is in operation: First, the drive assembly 77 drives the rollers to rotate by means of its built-in motor. The rotating rollers use friction to cooperate with the suspension rail 76 to drive the overall movement of the frame assembly 101, so as to move the bolt drill rig to a specified position according to actual needs. The provided load-carrying trolley 72 slides outside the suspension rail 76 to guide the overall movement of the frame assembly 101. When the bolt drill rig moves to the specified position, the braking assembly is used to fix between the bolt drill rig and the suspension rail 76.

[0075] After the movement of the bolt drill rig is completed, the piston rod of the luffing oil cylinder 205 is pushed to drive the boom 202 to drive the swing frame 201, the follower frame 203 and the boom support 204 to luff, so that the moving follower frame 203 drives the overall movement of the drill arm platform frame 301 by using the follower mounting seat 207, and the height between the drill arm platform frame 301 and the frame assembly 101 and the height of the bolt drill 502 are adjusted, so that the overall bolt drill rig can adapt to the working conditions of roadways with different heights.

[0076] After the height of the drill arm platform frame 301 is adjusted, the piston rod of the leg oil cylinder 74 is pushed to move the central leg 73, so as to support the middle of the frame assembly 101 by using the central leg 73. Then the drill arm platform frame 301 and the roadway ground are supported by the hydraulic side leg 75 to increase the overall stability of the bolt drill rig during operation, and the hydraulic upper boom 78 cooperates with the frame assembly 101 to extrude the top of the roadway, and the reaction force is used to further improve the overall stability of the bolt drill rig during operation.

[0077] When it is necessary to adjust the distance between the translational drill arm mechanism 4 and the slide rail type drill arm platform 3, the output shaft of the driving motor 603 drives the driving gear 604 to rotate. The rotating driving gear 604 cooperates with the rack 304 to drive the overall movement of the trolley carriage 601 through the tooth pattern. The moving trolley carriage 601 drives the translational drill arm mechanism 4 and the drilling rig assembly 5 as a whole to move horizontally along the drill arm platform frame 301, so as to preliminarily adjust the distance between the bolt drill 502 and the working section.

[0078] When it is necessary to adjust the angle or position between the bolt drill 502 and the working section, the translational oil cylinder 403 cooperates with the boom oil cylinder 404 to drive the translational mounting seat 405 to swing up, down, left and right. Then, the telescopic oil cylinder 406 pushes the overall movement of the telescopic inner frame 402, so as to drive the drilling rig assembly 5 through the translational mounting seat 405 to further finely adjust the distance from the working section.

[0079] When it is necessary to adjust the drilling direction of the bolt drill 502, the output shaft of the first spiral swing oil cylinder 503 drives the second spiral swing oil cylinder 504 and the bolt drill 502 as a whole to rotate. Then, the output shaft of the second spiral swing oil cylinder 504 drives the bolt drill 502 as a whole to rotate, so as to drive the bolt drill 502 to perform 360° dead angle free omnidirectional operation.

[0080] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present invention.
