[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] like Figures 1 to 8 As shown, a wall drilling device for construction projects includes a mounting frame 1 detachably installed on a lifting mechanism and a drilling rig 13 with a drill rod 14. The mounting frame 1 is provided with a guide rail structure extending along its length. A first sliding plate 5 is slidably mounted on the guide rail structure. A drive component 3 is mounted on the mounting frame 1 by bolts and nuts. The drive component 3 is an electric push rod or a hydraulic cylinder. The power end of the drive component 3 is connected and fixed to the first sliding plate 5. A first mounting plate 9 is fixedly mounted on the first sliding plate 5. The drilling rig 13 is fixedly mounted on a second mounting plate 12. The second mounting plate 12 is assembled with the first mounting plate 9 by bolts and nuts. A protective cover 17 is slidably mounted on the first sliding plate 5. The protective cover 17 is provided with a protective cavity surrounding the drill rod 14, the drilling rig 13, the first mounting plate 9, and the second mounting plate 12, providing operational protection during drilling. An adaptive adjustment mechanism 19 is provided between the first sliding plate 5 and the protective cover 17, which adaptively adjusts the position of the protective cover 17 on the first sliding plate 5 according to the working resistance during drilling.

[0022] The guide rail structure includes a first sliding groove 2 formed on the mounting bracket 1, and a first sliding frame 6 slidably assembled in the first sliding groove 2 on the first sliding plate 5. The cross-section of the first sliding groove 2 is U-shaped, and the cross-section of the first sliding frame 6 corresponds to that of the first sliding groove 2.

[0023] • In actual operation: When the drive component 3 is started, its power end pushes the first sliding plate 5 to move axially along the guide rail structure. At this time, the first sliding frame 6 and the U-shaped first sliding groove 2 form a three-sided constraint.

[0024] The first sliding frame 6 has a first sliding opening 10 and a second sliding groove 11 communicating with the first sliding opening 10. The lower end of the protective cover 17 is fixedly provided with a second sliding frame 16 that is slidably installed in the first sliding opening 10. The adaptive adjustment mechanism 19 includes a second sliding plate 15 fixedly installed on the second sliding frame 16. The second sliding plate 15 is slidably installed in the second sliding groove 11. A first elastic component 18 is provided between the second sliding plate 15 and the first sliding frame 6. The first elastic component 18 is an adaptive spring. The adaptive spring is movably installed in the second sliding groove 11, and one end is connected and fixed to the second sliding plate 15, and the other end is connected and fixed to the first sliding frame 6.

[0025] In actual operation: When the drill rod 14 contacts the working surface and generates axial resistance, the second sliding frame 16 drives the second sliding plate 15 to generate relative displacement within the second sliding groove 11. At this time, the first elastic component 18 undergoes compression deformation. Through the dynamic balance between the spring force and the drilling resistance, the protective cover 17 generates compensating displacement along the first sliding opening 10. When the resistance increases, the second sliding plate 15 compresses the adaptive spring and retracts into the second sliding groove 11, driving the protective cover 17 to move synchronously. When the resistance decreases, the adaptive spring pushes the second sliding plate 15 to reset, causing the protective cover 17 to re-fit the working surface. The closed fit between the U-shaped first sliding groove 2 and the first sliding frame 6 effectively constrains the displacement deviation of the first sliding plate 5. Example

[0026] Based on Example 1, such as Figures 9 to 11 As shown, the mounting bracket 1 is fixedly equipped with at least two parallel guide rods 4 along its length direction, and a support frame 7 is fixedly provided on the side of the first sliding plate 5. The support frame 7 has guide holes 8 that cooperate with the guide rods 4 to form a guide pair structure with clearance fit.

[0027] One of the guide rods 4 is equipped with an automatic positioning mechanism 20 that cooperates with the support frame 7. The automatic positioning mechanism 20 enables automatic positioning of the moving position of the support frame 7.

[0028] The automatic positioning mechanism 20 includes a positioning cavity 2001, in which a third sliding plate 2003 is slidably installed. A positioning rod 2002 is provided on the third sliding plate 2003, extending slidably out of the positioning cavity 2001. The positioning rod 2002 cooperates with the support frame 7. A second elastic component 2004 is provided between the third sliding plate 2003 and the positioning cavity 2001. A second detection contact 2006 is provided on the third sliding plate 2003. A first detection contact 2005 corresponding to the second detection contact 2006 is provided on the positioning cavity 2001.

[0029] Specifically: the positioning cavity 2001 is provided with a second sliding opening 2007, the positioning rod 2002 slides through the second sliding opening 2007, the second elastic component 2004 is a return spring, one end of the second elastic component 2004 is connected and fixed to the third sliding plate 2003, and the other end is connected and fixed to the positioning cavity 2001, and the first detection contact 2005 and the second detection contact 2006 are electrically connected to the driving component 3 through the controller.

[0030] In actual operation: when the support frame 7 moves to the position corresponding to the positioning rod 2002, it squeezes the end of the positioning rod 2002, forcing the third sliding plate 2003 to compress the second elastic component 2004 and retract into the positioning cavity 2001. When the second detection contact 2006 contacts the first detection contact 2005, it triggers the controller to cut off the power supply to the drive component 3, realizing the automatic positioning function. After the drilling operation is completed, the drive component 3 is started to drive the drill 13 to reset. At this time, the positioning rod 2002 pops out under the action of the reset spring.

[0031] An adjustment mechanism 19 is provided between the positioning cavity 2001 and the guide rod 4. Operating the adjustment mechanism 19 causes the positioning cavity 2001 to slide along the guide rod 4. The guide rod 4 is provided with scale lines. The adjustment mechanism 19 includes a connecting plate 1901 slidably mounted on the guide rod 4. The positioning cavity 2001 is mounted on the connecting plate 1901. A sleeve 1902 slidably mounted on the guide rod 4 is provided on the connecting plate 1901. The inner ring of the sleeve 1902 has a limit groove 1903. A fixed screw tube 1904 communicating with a limiting groove 1903 is fixedly installed on 1902. An arc-shaped limiting plate 1905 is slidably installed in the limiting groove 1903. A limiting bolt 1906 is rotatably installed on the arc-shaped limiting plate 1905, and the limiting bolt 1906 is threaded in the fixed screw tube 1904. By operating the limiting bolt 1906, the arc-shaped limiting plate 1905 is moved along the limiting groove 1903. Through the friction between the arc-shaped limiting plate 1905 and the guide rod 4, the sleeve 1902 is connected and fixed to the guide rod 4.

[0032] In actual operation: When the limiting bolt 1906 is rotated, the arc-shaped limiting plate 1905 moves radially along the limiting groove 1903, generating normal pressure that contacts the surface of the guide rod 4. When the torque is tightened, static friction is generated between the arc-shaped limiting plate 1905 and the guide rod 4, causing the sleeve 1902 to form a self-locking position. After the operator accurately positions it through the scale line, the position of the positioning cavity 2001 can be kept stable. When disassembling, the limiting bolt 1906 is rotated out in the opposite direction, and the arc-shaped limiting plate 1905 retracts into the limiting groove 1903 to release the friction lock.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
