A through groove 5 is vertically opened on the bearing surface of the supporting frame 2. The auxiliary moving frame 4 can be movably arranged in the through groove 5 up and down. A plurality of universal ball bearings 6 for moving the human defense safety door blocking plate are arranged at intervals on the upper end surface of the auxiliary moving frame 4. The lifting mechanism 3 is fixedly arranged below the through groove 5 and is connected to the auxiliary moving frame 4 to drive the auxiliary moving frame 4 to rise or fall along the through groove 5. Raising the auxiliary moving frame 4 can make the universal ball bearings 6 protrude from the supporting frame 2, lowering the auxiliary moving frame 4 can make the universal ball 6 hidden in the through groove 5. When drilling the civil air defense safety door blocking plate, place the civil air defense safety door blocking plate flat on the bearing surface of the support frame 2, control the lifting mechanism 3 to raise the auxiliary moving frame 4, so that the universal ball 6 on the upper end surface of the auxiliary moving frame 4 protrudes from the bearing surface of the support frame 2, and use a number of universal balls 6 to lift the civil air defense safety door blocking plate so that the civil air defense safety door blocking plate does not contact the bearing surface of the support frame 2. At this time, the operator can The civil defense safety door blocking plate is manually pushed to move its position. Under the action of the universal ball 6, the civil defense safety door blocking plate can be easily pushed, which is convenient for the staff to quickly adjust its position. After pushing it to the predetermined position, the lifting mechanism 3 is controlled to lower the auxiliary moving frame 4, so that the universal ball 6 is hidden in the through groove 5, and the civil defense safety door blocking plate is placed on the bearing surface of the support frame 2 again. The civil defense safety door blocking plate is pressed on the bearing surface of the support frame 2 by its own gravity, and the drilling machine 1 is turned on to drill it.

[0023] Specifically, the through slots 5 are arranged at intervals along the length or width direction of the support frame 2 and are evenly distributed on the bearing surface of the support frame 2. The auxiliary movable frame 4 includes a base frame 41 and a mounting frame 42. The mounting frame 42 is multiple and correspondingly arranged in each through slot 5. The mounting frame 42 is arranged in parallel and can move freely up and down in the through slot 5. The base frame 41 is arranged below the through slot 5 in parallel and can move up and down, and is fixedly connected with each mounting frame 42 as a whole. The base frame 41 can drive multiple mounting frames 42 to move up and down in the through slot 5. The universal ball 6 is arranged at intervals on the upper end surface of each mounting frame 42. There are four lifting mechanisms 3, which are distributed and fixedly arranged at the four corners below the bearing surface of the support frame 2. The lifting ends of the lifting mechanism 3 are respectively fixedly connected to the four corners or both sides of the base frame 41, and can synchronously drive the base frame 41 to rise and fall, so as to drive multiple mounting frames 42 to rise or fall synchronously along the through slot 5. When in use, when the human defense safety door blocking plate to be drilled is placed on the bearing surface of the support frame 2, the control The lifting mechanism 3 drives the base frame 41 to rise, so that several universal balls 6 protrude from the bearing surface of the support frame 2 at the same time, and the universal balls 6 are used to lift the civil air defense safety door blocking plate, so that the civil air defense safety door blocking plate does not contact the bearing surface of the support frame 2.

After pushing it to the predetermined position, the lifting mechanism 3 is controlled to lower the base frame 41, so that the universal balls 6 are hidden in the through groove 5, and the civil air defense safety door blocking plate is placed on the bearing surface of the support frame 2 again. Due to the large weight of the civil air defense safety door blocking plate, after being placed on the bearing surface of the support frame 2, the friction force with the bearing surface of the support frame 2 is large under the action of gravity. When the drilling machine 1 is turned on, it will not move easily during the drilling operation, so it does not need to be fixed. After the drilling operation is completed, the auxiliary moving frame 4 can be raised again to lift the civil air defense safety door blocking plate for easy transportation.

[0024] In the above embodiment, the lifting mechanism 3 can be a cylinder or a hydraulic cylinder, the telescopic arm of the cylinder or the hydraulic cylinder is connected to the base frame 41, the cylinder or the hydraulic cylinder is powered by an external air compressor or hydraulic machine, and is controlled by a solenoid valve to synchronously extend and retract, and synchronously drive the base frame 41 to rise and fall.

The positions of the first baffle 21 and the second baffle 22 are preset positions and are perpendicular to each other. The first baffle 21 and the second baffle 22 are used to limit the civil defense safety door sealing plate. When in use, the civil defense safety door sealing plate can be manually pushed in the direction of the first baffle 21 and the second baffle 22, so that the edge of the civil defense safety door sealing plate is against the first baffle 21 and the second baffle 22, and the first baffle 21 and the second baffle 22 are used to limit the civil defense safety door sealing plate, so that the civil defense safety door sealing plate can quickly reach the predetermined position.

[0027] Furthermore, a through hole 23 corresponding to the drilling position of the civil defense safety door blocking plate is longitudinally opened on the bearing surface of the support frame 2. The position of the through hole 23 is a preset position, which facilitates the penetration of the drill bit of the drilling machine 1 and the discharge of iron filings generated by drilling during the drilling operation.

[0028] Furthermore, in order to increase the friction between the sealing plate of the civil air defense safety door to be drilled and the support frame 2, an anti-skid pad 24 is laid on the bearing surface of the support frame 2, and the anti-skid pad 24 is made of rubber or PVC.

[0029] Please continue to see Figure 1 or Figure 2 Furthermore, when the drilling operation is carried out, the civil air defense safety door blocking plate is moved by a lifting tool such as a crane.

The sub-frame 7 is arranged at an end away from the first baffle 21 or on a side away from the second baffle 22. The height of the sub-frame 7 is consistent with the height of the support frame 2. Rollers 71 are arranged in parallel and at intervals on the upper end of the sub-frame 7. The rotation direction of the rollers 71 is facing the support frame 2. The sub-frame 7 is used to support and move the civil air defense safety door blocking plate. When the drilling operation is carried out, the civil air defense safety door blocking plate can be first lifted on the sub-frame 7, and then pushed to the support frame 2 through the sub-frame 7 for drilling operation. After the drilling is completed, the civil air defense safety door blocking plate can also be pushed to the sub-frame 7, which is convenient for lifting and handling and improves the operation efficiency.

[0030] When this device is used in practice, after the civil air defense safety door blocking plate to be drilled is placed on the bearing surface of the support frame 2, the lifting mechanism 3 is controlled to drive the base frame 41 to rise, so that several universal balls 6 protrude from the bearing surface of the support frame 2 at the same time, and the civil air defense safety door blocking plate is lifted up by the universal balls 6 so that the civil air defense safety door blocking plate does not contact the bearing surface of the support frame 2. At this time, the staff pushes the civil air defense safety door blocking plate to move on the support frame 2, adjusts its position, and pushes it to the predetermined position, and then controls the lifting mechanism 3 to lower the base frame 41, so that the universal balls 6 are hidden in the through groove 5, and the civil air defense safety door blocking plate is placed on the bearing surface of the support frame 2 again, and the drilling machine 1 is turned on to perform drilling operations. The device utilizes the rolling characteristics of the universal balls 6 to improve the flexibility of the movement of the civil air defense safety door blocking plate, facilitates the staff to quickly adjust the position of the civil air defense safety door blocking plate, and improves the drilling efficiency.
