Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a wall drilling device for fire protection engineering. Background Art

[0002] In modern construction projects, the fire protection system is essential. During the construction process, fire protection engineering is also an important task, mainly including the layout and installation of the fire protection pipeline system in the building and the installation and connection project of water pumps and fire hydrants. This project involves a large number of wall drilling operations, from large water pipe channel openings to a large number of bolt installation holes, which require construction workers to complete with the assistance of drilling equipment.

[0003] Most of the existing wall drilling equipment only has basic drilling functions and basically lacks the design of suppressing and protecting against a large amount of dust generated during the process. Prolonged operation is likely to cause damage to the health of construction workers.

[0004] In order to solve the above problems, we made improvements and proposed a wall drilling device for fire protection engineering. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

The left end of the electric drill is fixedly sleeved with an accessory outer sleeve through bolts. The top surface of the accessory outer sleeve is fixedly welded with a main limiting pipe, and the front and back surfaces of the accessory outer sleeve are fixedly welded with secondary limiting pipes. A main limiting rod is telescopically and slidably arranged inside the main limiting pipe, and a secondary limiting rod is telescopically and slidably arranged inside the secondary limiting pipe. A baffle is arranged at the left end of the electric drill, and two dust suppression nozzles are arranged in the middle of the baffle.

[0008] As a preferred technical solution of the utility model, the left end of the main limiting rod is fixedly welded to the middle of the top of the right side of the baffle. The two secondary limiting rods are respectively fixedly welded to the front and rear ends of the middle of the right side of the baffle. Springs are sleeved outside the two secondary limiting rods, and the left and right ends of the springs are respectively fixedly welded to the left end of the secondary limiting rod and the left side of the secondary limiting pipe.

Detailed implementation mode

[0018] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0019] Embodiment: As Figures 1-3 shown, a wall drilling device for fire protection engineering includes an electric drill 1. The left end of the electric drill 1 is fixedly sleeved with an accessory outer sleeve 2 through bolts. The top surface of the accessory outer sleeve 2 is fixedly welded with a main limiting pipe 3. The front and back surfaces of the accessory outer sleeve 2 are fixedly welded with auxiliary limiting pipes 7. A main limiting rod 4 is telescopically slidably arranged inside the main limiting pipe 3. An auxiliary limiting rod 6 is telescopically slidably arranged inside the auxiliary limiting pipe 7. A baffle 5 is arranged at the left end of the electric drill 1, and two dust suppression nozzles 10 are arranged in the middle of the baffle 5.

[0020] A drill bit through hole 501 is opened in the center of the baffle 5. The drill rod of the electric drill 1 passes through the drill bit through hole 501. Two nozzle mounting holes 502 are also opened in the middle of the baffle 5. The two nozzle mounting holes 502 are respectively located above and below the drill bit through hole 501. The two dust suppression nozzles 10 respectively pass through the baffle 5 through the nozzle mounting holes 502 and are fixedly connected to the baffle 5 by screws.

[0021] The left end of the main limiting rod 4 is fixedly welded to the middle of the top of the right side of the baffle 5. The two auxiliary limiting rods 6 are respectively fixedly welded to the front and rear ends of the middle of the right side of the baffle 5. Aluminum fine springs 8 are sleeved outside the two auxiliary limiting rods 6. The left and right ends of the spring 8 are respectively fixedly welded to the left end of the auxiliary limiting rod 6 and the left side of the auxiliary limiting pipe 7. The spring 8 is an aluminum fine spring.

[0022] Fixing feet 9 are fixedly installed at the four corner positions on the left side of the baffle 5 through bolts. The water outlets of the two dust suppression nozzles 10 point to the drilling position of the drill rod. Branch water delivery pipes 11 are fixedly connected to the right ends of the two dust suppression nozzles 10.

[0023] Fixed rings 12 are fixedly welded to the top and bottom of the auxiliary limiting pipe 7 on the front of the electric drill 1. The right ends of the two branch water delivery pipes 11 respectively pass through the two groups of fixed rings 12.

[0024] A tee pipe fitting 13 is arranged to the right of the auxiliary limiting pipe 7 on the front of the electric drill 1. The back of the tee pipe fitting 13 is fixedly connected to the right end of the front of the accessory outer sleeve 2 through bolts. The right ends of the two branch water delivery pipes 11 are respectively fixedly connected to the top and bottom of the tee pipe fitting 13. The right end of the tee pipe fitting 13 is fixedly connected to a submersible pump through a hose. The submersible pump is arranged in a water storage bucket.

[0025] Working principle: When using this kind of wall-drilling device for fire protection engineering, align the front end of the drill rod of the electric drill 1 with the position on the wall to be drilled and press against it. At this time, the fixing feet 9 of the baffle 5 also press against the wall synchronously. Start the electric drill 1, and the drill rod starts to rotate. At the same time, start the submersible pump in the water storage bucket to supply water to the dust suppression nozzle 10 through the hose, the tee fitting 13 and the branch water delivery pipe 11, and then the wall-drilling operation can start. During the process, as the drill rod goes deeper, the baffle 5 maintains the support against the wall under the action of the spring 8 and the secondary limit rod 6. The elastic force of the aluminum fine spring is small and will not interfere with drilling, which can ensure that the baffle 5 always blocks the drilling position, and the dust suppression nozzle 10 continuously sprays water at the drilling position to suppress the generation of dust.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
