[0025] It should be noted that the control method of the present application is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present application is mainly used to protect mechanical devices, so the present application will no longer explain the control method and circuit connection in detail.

[0026] See also Figure 1-3The spray mechanism includes two guide rods 701 fixed between the upper and lower inner walls of the installation bin 4, and a guide block 702 is slidably connected to the outer peripheral wall of the guide rod 701, and a protective cylinder 703 is slidably connected between the two guide blocks 702. The bottom surface of the installation bin 4 is provided with a movable hole for the protective cylinder 703 to penetrate and slide up and down inside it. The protective cylinder 703 is sleeved on the outer peripheral wall of the drill bit 6, and the guide rod 701 is used for the guide block 702 to slide up and down along its outer peripheral wall. The protective cylinder 703 is a transparent circular cylinder, and a magnetic ring is fixed to the bottom surface of the protective cylinder 703. When in use, the lifting cylinder 3 drives the installation bin 4 to move downward, so that the bottom of the protective cylinder 703 first contacts the upper surface of the steel structure, and then the lifting cylinder 3 continues to move downward, so that the drill bit 6 contacts the upper surface of the steel structure and is adsorbed on the upper surface of the steel structure through the magnetic ring, and then the drill bit 6 is driven by the motor 5 to rotate to perform drilling. The protective cylinder 703 can effectively prevent debris from splashing, and the wall of the protective cylinder 703 An annular groove 704 is provided inside the housing 1, a water pump 705 is fixed on the back of the housing 1, a transverse pipe 706 is fixed on the back of the housing 1, a connecting pipe 707 fixed to the top of the transverse pipe 706 and the water inlet end of the water pump 705 is fixed, and a water delivery pipe 708 is fixed to the water outlet end of the water pump 705 and one end of which is fixed to the top of the protective tube 703 and connected to the annular groove 704. A plurality of water outlet holes 709 connected to the annular groove 704 are provided on the inner peripheral wall of the protective tube 703. The protective tube 703 and the annular groove 704 are located on the same central axis, and multiple water outlet holes 709 are evenly distributed along the circumferential direction of the protective tube 703. The water supply pipe 708 is a corrugated hose. When drilling, the water pump 705 is started. The water pump 705 draws out the spray liquid inside the box 1 through the connecting pipe 707 and the cross pipe 706, and transports it to the annular groove 704 inside the protective tube 703 through the water supply pipe 708. Further, it is sprayed on the drill bit 6 through the water outlet hole 709 to cool it down.

[0027] See also Figure 3-4In this embodiment, the recovery mechanism includes a porous plate 801 fixed between the rear inner walls of the box body 1, a circular bin 802 is threadedly connected to the rear end of the transverse tube 706, a magnetic rod 803 is fixed to the front of the circular bin 802, and a film bag 804 is set on the outer peripheral wall of the magnetic rod 803. When spraying and cooling, the sprayed spray liquid flows downward to the bottom wall of the box body 1 for storage, and the water pump 705 extracts the spray liquid through the transverse tube 706. When passing through the transverse tube 706, the magnetic rod 803 can adsorb the steel debris in the spray liquid on the outer surface of the film bag 804, so as to collect the steel debris. Two positioning blocks 805 are fixed to the front of the circular bin 802, and an annular plate 806 is slidably connected to the outer peripheral wall of the film bag 804. Two positioning holes 807 for the positioning blocks 805 to pass through are provided on the right side of the annular plate 806. There are two limit blocks 808 fixed on it. The film bag 804 is a T-shaped structure and its left side extends to between the annular plate 806 and the circular bin 802. The front of the circular bin 802 is open. The inner wall of the circular bin 802 and the outer wall of the transverse tube 706 near the rear end are provided with mutually compatible threaded grooves. When it is necessary to clean the steel debris, the circular bin 802 is rotated to disengage it from the threaded connection with the transverse tube 706. At this time, the circular bin 802 can be moved backward and the magnetic bar 803 can be pulled out of the transverse tube 706. Further, the annular plate 806 is slid to the right to remove the film bag 804. When the film bag 804 is separated from the magnetic bar 803, the steel debris adsorbed on the outer surface of the film bag 804 loses its magnetic attraction and automatically falls off for easy recovery. Then the above operation is reversed to make the annular plate 806 cooperate with the circular bin 802 and the limit blocks 808 to clamp the film bag 804.

[0028] Clamping cylinders are installed on the left and right sides of the box body 1 and on the top of the porous plate 801 . The box body 1 and the bottom of the porous plate 801 are filled with spray liquid. The magnetic rod 803 is located in the horizontal tube 706 .

[0029] The working principle of the above embodiment is:

[0030] (1) When in use, the lifting cylinder 3 drives the installation bin 4 to move downward, so that the bottom of the protective tube 703 first contacts the upper surface of the steel structure, and then the lifting cylinder 3 continues to move downward, so that the drill bit 6 contacts the upper surface of the steel structure, and then the drill bit 6 is driven by the motor 5 to rotate to perform drilling. The protective tube 703 can effectively prevent debris from splashing. When drilling, start the water pump 705. The water pump 705 draws out the spray liquid inside the box 1 through the connecting pipe 707 and the cross pipe 706, and transports it to the annular groove 704 inside the protective tube 703 through the water supply pipe 708. Further, it is sprayed on the drill bit 6 through the water outlet 709 to cool it down.

[0031] (2) During the spray cooling, the spray liquid flows downward to the bottom wall of the box body 1 and is accumulated. The water pump 705 extracts the spray liquid through the transverse tube 706. When passing through the transverse tube 706, the magnetic rod 803 can adsorb the steel debris in the spray liquid on the outer surface of the film bag 804, thereby collecting the steel debris. When it is necessary to clean the steel debris, the circular bin 802 is rotated to disengage it from the threaded connection with the transverse tube 706. At this time, the circular bin 802 can be moved backward and the magnetic rod 803 can be pulled out of the transverse tube 706. Further, the annular plate 806 is slid to the right to remove the film bag 804. When the film bag 804 is separated from the magnetic rod 803, the steel debris adsorbed on the outer surface of the film bag 804 loses its magnetic attraction and automatically falls off for easy recovery. Then the above operation is reversed to make the annular plate 806 cooperate with the circular bin 802 and the limit block 808 to clamp the film bag 804.
