In order to achieve the positioning effect of the positioning screw 11 on the flat plate 4, the positioning screw 11 is placed on the end face of the flat plate 4 with a plurality of protrusions. The friction force between the positioning screw 11 and the flat plate 4 is increased to achieve a better positioning effect.

In the specific use of the present invention, an electric drill is firstly installed in the center of the movable plate 6. The electric drill is driven by a driving motor placed on the lower end face of the movable plate 6. The center of the electric drill and the center of the through hole are on the same vertical line. When in use, install the drill bit of the size to be used on the electric drill. In the initial position, the movable plate 6 is located at the bottom of the guide groove 12. Align the center of the through hole with the position to be drilled. After aligning the position, hydraulically control the telescopic sleeve. The cylinder 19 is lifted upwards, and the telescopic sleeve 19 is lifted upwards, and at the same time, the whole device is moved upwardly through the bottom plate 1 until the pressure plate 7 is pressed against the top beam plate; At this time, the operator can drive the adjusting screw 9 to rotate by rotating the turntable 13. Since the adjusting screw 9 and the plate 4 are connected by a thread, the adjusting screw 9 can move upward while rotating, and then rotate with the adjusting screw 9. The connected bracket 8 drives the movable plate to move upward, the upward movement of the movable plate 6 will drive the electric drill to move upward, and the drill bit will drill through the through hole. Through the control of the rotation direction of the turntable 13, the operator can easily control the rise of the drill bit. In the drilling process, since the upper end of the pressing plate 7 is provided with a groove 20, the debris generated during the drilling process will be scattered in the groove 20, and will not be scattered around, while operating When the personnel rotates the turntable 13, they are located on the side of the drilled hole, and the debris will not be lost to the eyes, which is convenient for operation.

In addition, since the flat plate 4 can rotate around the support column 3, when the bottom plate 1 moves upward, if the top beam plate is not in a horizontal state, the pressing plate 7 will rotate under the action of extrusion when it contacts the top plate, until the pressing plate 7 and the top plate are in a horizontal state. The beam and the plate are completely fitted, and the upward movement is stopped at this time. At this time, the operator rotates the positioning screw 11 to make the inner end face of the positioning screw 11 squeeze the plate 4. Since the inner end face of the positioning screw 11 is provided with a protrusion, it is in contact with the plate 4. When the 4 contacts, the positioning of the plate 4 after rotation can be effectively achieved by the extrusion force of the thread, and the simultaneous operation of the positioning screws 11 on both sides can make the positioning of the plate 4 more reliable, stable and safe; after that, the operator rotates the turntable. 13 Carry out the drilling operation. Since the movable plate 6 is slidably installed in the guide plate 5, the movable plate 6 can slide along the guide plate 5, and the guide plate 5 is fixed with the movable plate 6, the flat plate 4 and the adjusting screw 9. The plate 6 and the adjusting screw 9 will follow the rotation, and the moving direction of the drill bit will always be in a vertical state with the pressure plate 7. Since the pressure plate 7 and the top beam plate are completely fitted, the pressure plate 7 and the top beam plate are in a parallel state. At this time, drilling is being carried out. During operation, the drill bit is always kept perpendicular to the top beam plate to avoid the problem of easy breakage of the drill bit during the drilling process caused by the inclined wall.

In addition, since the flat plate 4 can be rotated on the support column 3, in order to avoid the inclination of the flat plate 4 under normal conditions, when the flat plate 4 is in a normal state, in order to maintain the level of the flat plate 4, the lower left and right sides of the flat plate 4 are symmetrical. Spring 10 and balance plate 15, under the condition that the compression springs 10 on both sides are under the same force, the stretching length is the same, so that the flat plate 4 is kept in a horizontal state. 18. Make the rotating block 17 in a vertical state, and the lower end of the balance plate 15 is slidably installed in the rotating block 17. Under the action of the rotating block 17, the flat plate 4 will be in a vertical state under the action of the balance plate 15; when the pressure plate 7 When it comes into contact with the inclined wall, under the action of the upward lifting force, the compression springs 10 on both sides will be stretched on one side and compressed on the other side, and the rotating blocks 17 on the bottom plate 1 will rotate in the same direction to adapt to the For different inclined top beam plates, when the bottom plate 1 moves downward, the flat plate 4 will return to a horizontal state under the action of the compression spring 10 and the balance plate 15 .

By designing the combination of the pressing plate 7 and the flat plate 4 that can adapt to the top wall with different inclinations, the present invention can avoid deviation during drilling due to the unevenness of the wall during the drilling process of the top beam plate. It is easy to cause the phenomenon of drill bit breakage. In addition, it is convenient to drill holes for some special walls, which improves the versatility.

The invention designs the positioning screws 11 symmetrical on both sides, which can effectively realize the positioning of the flat plate 4 when drilling the inclined wall, which makes the drilling process more stable, improves the work safety, and can effectively avoid The problem of drill bit breakage caused by shaking during work.

In the present invention, the balance plate 15, the rotation block 17 and the compression spring 10 are designed to cooperate with each other, so that the flat plate 4 can be kept in a horizontal state in a normal state, which facilitates the drilling operation of the regular roof beam plate. After the operation is completed, the flat plate 4. It will automatically return to the horizontal state, no need to think about the operation, which improves the work efficiency.

When the present invention is in use, the operator only needs to control the hydraulic jacking device to lift the device, so that the pressing plate 7 of the device is completely fitted with the top beam plate. After being completely fitted, the operator only needs to rotate the turntable 13 to adjust the screw The threaded connection with the flat plate 4 can control the drilling operation smoothly, and at the same time, the threaded connection can effectively control the depth of the drilling, saving time and effort.

The invention has ingenious structure and novel design, and effectively solves the problem that the drill bit is prone to breakage when the wall is uneven during the drilling process of the roof beam plate.
