Description

Technical Field

[0001] The present invention relates to the technical field of coal mine mining, and particularly relates to a drilling rig for the main frame platform of a gantry-type single-rail hydraulic bolt drill jumbo. Background Art

[0002] In the traditional tunneling support process, after the roadheader cuts, during the cutting process, the roof is in a state of unsupported roof. It is necessary to wait for the roadheader to withdraw and the bolt drill jumbo to drive in, or for the roadheader-anchoring machine to complete cutting before the support platform can be deployed. The steel strip and steel mesh are temporarily hung and lifted to support the roof. The unsupported roof time is long, and it is not suitable for long tunneling. Only short tunneling and short support can be carried out, which poses a great safety hazard. Using a single-rail bolt drill installed on the gantry leg, although the problem of unsupported roof is solved and timely support can be achieved, the drill is installed on the leg or the crossbeam of the gantry. When installed on the leg, it can be horizontally telescoped, but it cannot telescope towards the heading face. The telescopic stroke of the boom itself is limited, and it cannot drill the top bolts over a long distance. Therefore, it still cannot achieve long tunneling and one-time support to achieve the goal of high-efficiency production. If a cantilever single-rail bolt drill jumbo is purchased, for the lifting of the on-board platform, the roadheader needs to retreat a long distance. If the floor is coal or mud, or in the up and down slopes, it is very easy to slip due to being pressed by coal mud, or even get stuck, resulting in a worse floor environment and affecting production efficiency. Therefore, a drilling rig for the main frame platform of a gantry-type single-rail hydraulic bolt drill jumbo is proposed. Summary of the Invention

[0030] In this embodiment, specifically, a first oil cylinder 20 and an upper support leg 21 are symmetrically hinged to the upper surface of the main frame 10. The piston rod of the first oil cylinder 20 is hinged to the outer wall of the upper support leg 21. The operation room 2 is electrically connected to the first oil cylinder 20 through an electric wire. Through the above settings, the first oil cylinder 20 drives the upper support leg 21 to move, so as to bring the upper support leg 21 into contact with the roadway roof wall and be used to stabilize the position of the main frame 10.

[0031] In this embodiment, specifically, the support and bracing mechanism 18 includes a mounting column 180, a telescopic outer sleeve 181, a telescopic inner sleeve 182, a tipping oil cylinder 183, a lower leg 184, and a second oil cylinder 185.

[0037] (3) The track and chain of the single rail hoist and the track connector, part of the height are hidden in the height space of the operation cab 2.

[0038] (4) The height of the boom and the support platform is less than the height of the operation cab 2.

[0039] During the operation of the present invention: During the process of driving towards the tunneling face, relevant personnel then install five drilling rigs on three front drill arms 11 and two rear drill arms 13 respectively. The relevant personnel start the support oil cylinder 171 through the operation room 2. The piston rod of the support oil cylinder 171 drives the support legs 170 to retract and be horizontally arranged on both sides of the main frame 10. The translation mechanism 12 and the support mechanism 15 are horizontally arranged on the main frame 10. Then, the relevant personnel start the drive unit 140 through the operation room 2. The drive unit 140 moves on the hanging rail 16, and the drive unit 140 drives the crossbeam 141 to move. Among them, the load-carrying trolley 142 is used to assist the crossbeam 141 to move, so that the crossbeam 141 assists the main frame 10 to move. The main frame 10 drives the front drill arm 11, the translation mechanism 12, the rear drill arm 13, the support mechanism 15, the support mechanism 17 and the drilling rig to walk on the hanging rail 16.

[0040] Upon arriving at the working face, the relevant personnel then start the support oil cylinder 171 through the operation room 2. The piston rod of the support oil cylinder 171 drives the support legs 170 to move, so that the support legs 170 are vertically arranged to support the position of the main frame 10.

[0041] A steel belt and steel mesh are hung below the support mechanism 15 and bundled, folded, fixed and contracted. Then, the relevant personnel start the support platform 150 and the front support legs 151. The support arms of the support platform 150 extend, and the steel belt and steel mesh are lifted and pressed tightly against the already supported roadway roof. Then, the front support legs 151 are used to support the position of the support platform 150.

[0042] Then, the relevant personnel start the translation oil cylinder 121, the support arm oil cylinder 124 and the telescopic oil cylinder 125 through the operation room 2 to adjust the drilling rigs on the front drill arm 11 and the rear drill arm 13 and the operation room 2 to sink without touching the platform. People stand in the standing platform of the operation room 2 to operate the drilling rig and move forward to the working area for drilling multiple rows of anchor bolts and cable bolts.

[0043] The drilling rigs on the front two sides first drill the roof anchor bolts and the side rib shoulder socket anchor bolts. The drilling rigs in the middle of the front mainly drill the roof anchor bolts in the middle of the roadway and some cable bolts, and drill the anchor bolts or cable bolts for hanging the track.

[0044] The two drilling rigs at the rear are mainly responsible for supplementary drilling to complete the anchor bolts at the middle and lower parts on both sides and the cable bolts that are allowed to lag behind on the roof according to the process.

[0045] 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, and these should all be covered within the protection scope of the present invention.
