Automatic sequential drill rod downward sliding drill rod box opened based on gravity action

Abstract

The invention relates to an automatic sequential drill rod downward sliding drill rod box opened based on the gravity action, and belongs to the field of drilling machine equipment. A box body is included. The box body is provided with a plurality of rows of drill rod bins. The lower ends of the drill rod bins are provided with drill rod outlets. The drill rod outlets are obliquely provided with rolling plates for bearing a drill rods, and the drill rods automatically and sequentially downwards slide to the drill rod outlets in the drill rod bins through the gravity and automatically and sequentially roll along the rolling plates through the gravity. An overturning plate rotationally connected the box body is arranged between every two adjacent drill rod bins and is in a work stop state under the simultaneous action of the drill rods in the two rows of drill rod bins adjacent to the overturning plate, wherein the overturning plate loses the acting force of the drill rods in the drill rod bin adjacent to overturning plate and close to one side of the drill rod rolling direction, and meanwhile the overturning plate is overturned into the work releasing state under the acting force ofthe drill rods in the drill rod bin which is adjacent to the overturning plate and gets away from one side of the drill rod rolling direction. The multiple rows of drill rod bins and the drill rods in each row of drill rod bins are discharged out of the bins in sequence. The overturning plates are easily overturned, and the situation that opening cannot be achieved due to jamming is avoided.

Description

technical field [0001] The invention belongs to the field of drilling rig equipment, and relates to a drill rod box for automatically sequentially sliding down drill rods that is opened under the action of gravity. Background technique [0002] In the coal mining industry, the drill rod box is an auxiliary device for drilling rigs, and its function is to provide the drill rods required for drilling to the drilling rig. Such as figure 1 with figure 2 As shown, the existing drill rod box of the drilling rig includes a connecting plate 1, a drilling rod box body 2, an inclination angle oil cylinder 3 and a flat plate 5, and the connecting plate 1 is connected to the drilling rig with bolts during use. Such as image 3 with Figure 4 As shown, in the drilling work of the drilling rig, after each drilling rod is drilled, the manipulator 6 stretches out, grabs a drilling rod 4 from the existing drilling rod box of the drilling rig, and reciprocates like this. Wherein, when d...
