Mining crane which is convenient to install

An easy-to-install mining crane includes a symmetric back-and-forth base, characterized in that a support pillar is fixed on the upper end surface of the base;

• A fixed block is fixed at the upper end of the support column, and a traveling device is provided between the fixed block, the support column and the base. The traveling device includes four rotatable traveling wheels. When the traveling wheel rotates, Drive the fixed block to move, a lifting device is provided in the fixed block, the lifting device includes a rewindable hook for lifting heavy ore;
• A left-right symmetrical support rod is provided in the fixed block, and a rotation device is provided in the support rod. The rotation device includes a threaded cavity, and a groove is provided on the upper side of the threaded cavity. A rack is provided with a sliding groove on the lower side of the threaded cavity, and a spline shaft is rotatably provided in the threaded cavity. A telescopic rod splined to the spline shaft is provided in the thread of the threaded cavity. There is a regulating device inside the rod, the regulating device includes a rotating gear that can be rotated to mesh with the rack, a plug block is slidably arranged on the lower side of the eighth bevel gear, and the lower end of the plug block can extend to the In the sliding groove, the spline shaft rotates to drive the telescopic rod to rotate and move. When the plug block extends into the sliding groove, the rotating gear meshes with the rack, then the spline The rotation of the shaft drives the telescopic rod to move only, so that the rotating gear rotates;
• A support block is fixed at an end of the telescopic rod far from the center of symmetry, and the support block abuts a wall to fix the position of the fixed block. A support device is provided in the support block, and the support device includes four For a rotating drill, the rotation of the rotating gear can provide power for the rotation of the drill, so that the drill is drilled into the wall, and the installation stability of the fixed block is improved.
