Description

Technical Field

[0001] The present invention relates to the technical field of wall construction, and in particular to a support device for a drilling machine used for drilling holes in house walls. Background Art

[0002] In the fields of decoration and building construction, drilling operations are common tasks. At present, there are various types of drilling machines on the market. Among them, conventional handheld drilling machines are widely used. Specifically, reference can be made to a wellbore geological monitoring water drilling machine disclosed in a Chinese patent with an application number of CN202410305335.8. It has multiple groups of handles, which are convenient for operators to hold and apply force, and is flexible to use, and can meet the drilling requirements of various scenarios. For drilling machines with brackets, the specific structure can be referred to a construction and installation water drilling machine disclosed in the Chinese patent application text with an application number of CN202123243316.8. Although the bracket can provide driving force for horizontal or vertical movement, it is connected to the drilling machine through structures such as bolts. The drilling machine needs to be equipped with corresponding installation mechanisms, and such drilling machines do not have handles and are non-standard drilling machines specifically matched with the brackets.

[0003] For decoration teams, they usually have various types of drilling machines with different models and specifications. Due to the flexibility of use, they prefer handheld drilling machines. However, when performing high-altitude drilling operations such as on the side wall at a high position or at the ceiling height, handheld drilling machines are inconvenient to operate and have high safety risks. And the drilling machines fixedly connected to the brackets have limited usage scenarios and low usage frequencies, resulting in the need for operators to be equipped with both handheld drilling machines and high-altitude wall drilling machines at the same time, which undoubtedly increases the purchase cost. Therefore, it is of great practical significance to develop a bracket that can adapt to the limit of different models of handheld drilling machines, so that the handheld drilling machine and the bracket are combined to form a high-altitude operation drilling machine. Summary of the Invention

[0004] Aiming at the disadvantages that existing decoration teams need to be equipped with both handheld drilling machines and high-altitude operation drilling machines at the same time, resulting in relatively high purchase costs, the present invention provides a support device for a drilling machine used for house walls, which can quickly clamp different models of handheld drilling machines.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A support device for a drilling machine used for drilling holes in house walls, comprising: a movable bracket, including a bracket body that can be translated and limited after translation, and a mounting seat that vertically moves and is limited along the bracket body; and further comprising

[0007] The flipping and clamping module includes a flipping frame and a clamping module. The flipping frame reciprocates along the drilling direction of the drilling machine on the mounting base. The clamping module includes a clamping box rotatably arranged on the flipping frame and capable of being limited in position after rotating a preset angle each time, and clamping components circumferentially spaced on the inner circumferential wall of the clamping box;

[0008] The clamping component includes a plurality of clamping pieces spaced along the insertion direction of the clamping box. The clamping pieces are elastically telescopic along the direction perpendicular to the insertion direction of the clamping box, and the telescoping of all the clamping pieces is controlled by a first electromagnetic control component;

[0009] The locking component can synchronously lock or unlock all the clamping pieces in the extended state with different extended strokes.

[0010] With the above scheme, a flipping and clamping module is added. The clamping box of the flipping and clamping module can be limited in position every time it rotates a certain angle relative to the flipping frame. The design purpose is that the handle angles of different models of handheld drilling machines are different. By adjusting and limiting the angle of the clamping box, it can ensure that the drill bit of the final drilling machine remains horizontal or vertically upward, and ensure that the drilling direction is consistent with the direction of the drill bit; a clamping module is added. The clamping component includes a plurality of clamping pieces. After these clamping pieces partially extend, they can elastically fit with the outer walls of different curvatures and shapes at the insertion end of the drilling machine, and use the locking component to limit the positions of all the clamping pieces with different strokes, so as to form an interference coating cavity that wraps around the outside of the insertion end of the drilling machine between the clamping pieces, thereby realizing the axial and circumferential limitation of the drilling machine. The support device carries the clamping box to realize vertical lifting and horizontal reciprocating motion, and can adapt to different sizes and models of handheld drilling machines.

[0011] Preferably, the locking component includes a first rack and a first tooth block. The first rack is arranged on the outer wall of each clamping piece and along its telescopic direction. The first tooth block elastically telescopes in the clamping box and can engage or disengage with the first rack. The first tooth block telescopes synchronously and is controlled by an inclined plane matching component.

[0012] Preferably, the inclined plane matching component includes a driving rod elastically telescoping at the bottom of the clamping box. The number of driving rods is the same as the number of groups of the clamping components. One end of the driving rod close to the clamping box includes a matching inclined block corresponding to each clamping piece in the corresponding clamping component and an avoidance connecting rod connecting adjacent matching inclined blocks. A first matching through groove for matching with the matching inclined block is arranged on the first tooth block. When the driving rod elastically extends, the first tooth block is in a retracted state; when the driving rod contracts, the first tooth block is in an extended state.

[0013] With the above - mentioned solution, by only controlling the telescoping of the driving rod, the telescoping of all the first tooth blocks can be synchronously controlled. Since the extending stroke of all the clamping members is related to the shape of the insertion end of the drilling machine, if the insertion end is of a special shape, it will inevitably lead to inconsistent extending strokes of the clamping members, which will result in that not all the first tooth blocks can engage with their corresponding clamping members, and the extending strokes of the first tooth blocks will also be different. However, the above design will not interfere with the extending amount of the first tooth blocks. Therefore, there must be a certain number of first tooth blocks that can engage with the clamping members, thereby forming the telescoping limitation of the corresponding number of clamping members.

[0014] Preferably, each clamping member corresponds to two first tooth blocks distributed oppositely and in a staggered - tooth state. The driving rod includes a main body rod inserted and matched with the bottom of the clamping box and a split rod that cooperates with the first tooth blocks on both sides of the clamping member at the same time. The cooperating inclined block and the avoiding connecting rod form the split rod.

[0015] With the above - mentioned solution, first tooth blocks are arranged on both sides of the clamping member, and the two are in a staggered - tooth state and synchronously controlled by the same driving rod. Such a design is that the first tooth blocks on both sides move synchronously. Since the two are arranged in a staggered - tooth manner, there must be a first tooth block that can engage with the clamping member. Such a design can increase the number of clamping members restricted and improve the clamping performance.

[0016] Preferably, a pressing and adsorbing assembly that can adsorb the end of the insertion end of the drilling machine and limit the insertion depth elastically telescopically at the center of the bottom of the clamping box. The pressing and adsorbing assembly includes a pressing and adsorbing mechanism and a locking mechanism. The pressing and adsorbing mechanism forms a negative pressure and adsorbs the insertion end of the drilling machine as the insertion end of the drilling machine inserts and partially retracts, and the locking mechanism restricts the movement of the pressing and adsorbing mechanism after retraction.

[0017] With the above - mentioned solution, adding an adsorption structure for the insertion end of the drilling machine can further increase the firmness of clamping the drilling machine.

[0018] Preferably, the pressing and adsorbing mechanism includes a fixed tube fixed at the center of the bottom of the clamping box and a moving tube elastically and sealingly sleeved outside the fixed tube. An exhaust valve for one - way exhausting outward is arranged at one end of the fixed tube away from the opening end of the clamping box, and an air - supplementing member that can be opened and closed is arranged on the fixed tube.

[0019] With the above - mentioned solution, the exhaust valve can exhaust the gas between the fixed tube and the moving tube. When the moving tube moves in the reverse direction, a negative pressure will be formed at the sealing and fitting part between the end of the moving tube and the drilling machine.

[0020] Preferably, the locking mechanism includes a second rack and a second tooth block. The second rack is located on the outer wall of the pressing and adsorbing mechanism and is arranged along its telescoping direction. The second tooth block elastically telescopes in the clamping box and can engage with or disengage from the second rack. The contraction of the second tooth block is controlled by the second electromagnetic control assembly.

[0021] Preferably, the extension and retraction of the driving rod is controlled by the extension and retraction of the second tooth block. The second tooth block is vertically plugged into the main rod. A second matching through groove is provided on the main rod. The second tooth block has a pressing inclined surface that matches the second matching through groove. When the second tooth block extends, the main rod retracts; when the second tooth block retracts, the main rod extends elastically.

[0022] By adopting the above scheme, the movement of the driving rod and the movement of the second tooth block are linked and coordinated, and the synchronous limit of all the clamping parts and the limit of the moving tube can be achieved by adopting a set of electromagnetic control components. The movement trend of the conventional moving tube is opposite to the movement trend of the driving rod, and two groups of electromagnets with opposite power gain and loss states need to be set. Each group may need to set the corresponding number of electromagnets according to the number of driving rods and connect them in series. There are problems such as insufficient internal installation space and difficult and disorderly lines. The present design can solve the above problems.

[0023] Preferably, an air circuit control component is provided between the clamping member and the clamping box, and the air circuit control component can synchronously realize independent changes in the air pressure of each clamping member.

[0024] Preferably, the gas circuit control component includes

[0025] An independent air path assembly includes a first air groove provided in each clamping member, a plurality of second air grooves independently connected to the first air groove at the bottom of the clamping box, and a connecting hose connecting the first air groove and the second air groove;

[0026] The vacuum assembly includes a piston plate and a piston rod that moves in a sealed manner in the second air groove. All piston rods are synchronously connected to the piston plate. The piston plate moves and is sealed in the first matching cavity. All piston plates are synchronously connected to a moving plate. The movement of the moving plate is controlled by a cylinder built into the clamping box.

[0027] By adopting the above scheme, the movement of the movable plate is controlled by the extension and retraction of the cylinder, thereby realizing the synchronous movement of all piston rods and the independent control of the internal air path of each clamp. The clamp in contact with the drilling machine can be adsorbed on the drilling machine, further increasing the firmness of clamping the drilling machine.

[0028] Preferably, both ends of the clamping box are rotatably connected to the flip frame via a rotating shaft, and the flip frame is provided with an engaging toothed disc that can be extended and retracted along the axial direction of the rotating shaft. The movement of the engaging toothed disc is controlled by a screw handle, and a matching tooth groove for the engaging toothed disc to engage is fixed on the outer wall of the clamping box with the rotating shaft as the center.

[0029] By adopting the above solution, the position of the meshing toothed disc along its axial direction can be adjusted by turning the screw handle, thereby achieving the meshing or disengagement of the meshing toothed disc and the matching tooth groove.

[0030] Preferably, the bracket body includes a moving component and a supporting component, the moving component includes a moving base, rollers rotating on the moving base, and an adsorption component that can be adsorbed or desorbed from the ground; the supporting component includes a fixed frame fixed on the moving base and a lifting frame vertically lifted at the upper end of the fixed frame, and the mounting seat is vertically lifted on the lifting frame.

[0031] By adopting the above scheme, the movable base is moved by rollers and limited by adsorption components. The vertical lifting of the lifting frame relative to the fixed frame can adjust the maximum stroke of the flip clamping module, and the lifting frame is used to achieve the lifting accuracy of the flip clamping module.

[0032] The present invention has significant technical effects due to the adoption of the above technical solutions: the mobile base can realize rapid movement on the ground by means of rollers, and can be adsorbed to limit the position after moving to the specified position, the lifting and lowering of the lifting frame can adjust the maximum lifting stroke, and the final height reached by the drilling machine is achieved through the vertical movement stroke of the mounting seat, the drilling machine moves horizontally on the mounting seat to advance or retreat the drilling machine, and the angle adjustment of the drilling machine on the flip frame is used to realize that the drilling direction of the drilling machine after clamping remains in the horizontal or vertical direction, and the multiple clamping members in the internal clamping assembly are elastically extended after being provided. It can elastically fit with the outer wall of the drill handle or the insertion part with different degrees of undulation, and the press-adsorption component can provide negative pressure to limit the end face of the drill insertion part. The locking component finally synchronously locks all the clamps and moving tubes with different extension strokes to ensure the maintenance of the locking force and the adsorption force. Negative pressure can also be formed at the end of the clamp to further increase the limitation of the drill insertion part and ensure the stable operation of the drill. The support device can adapt to the limitation of drills of different sizes and models, and ensure that the drilling direction of the drill can be adjusted to horizontal or vertical upward after the drill is limited.

[0044] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0045] A drilling machine support device for drilling holes in a house wall, as shown in reference to Figures 1 - 10 , includes a moving support and a flipping and clamping module. The moving support can be translated and limited after translation. The flipping and clamping module is used to clamp drilling machines of different models and carry the drilling machine to move vertically or horizontally along the moving support.

[0046] Specifically refer to Figures 1 - 2As shown in the figure, the mobile support includes a support body and a mounting seat 10. The support body includes a moving component and a supporting component. The moving component includes a moving base 1, rollers 2 rotatably mounted on the moving base 1, and an adsorption component that can adsorb or desorb from the ground. The adsorption component includes a first height-adjusting handle 42 vertically screwed to the moving base 1. A hard suction cup 41 is rotatably fitted to the bottom of the first height-adjusting handle 42. A rubber ring is fixed to the bottom edge of the chassis. A piston member is hermetically moved inside the suction cup 41. A second height-adjusting handle 43 is rotatably provided at the upper end of the piston member. The second height-adjusting handle 43 is screwed and fitted with the central threaded hole of the first height-adjusting handle 42. The vertical lifting of the suction cup 41 can be achieved by the first height-adjusting handle 42, and the lifting of the piston member and thus the adsorption and desorption of the suction cup 41 from the ground can be achieved by the second height-adjusting handle 43, realizing the limitation or release of the limitation of the moving base 1. The supporting component includes a fixing frame 3 fixed on the moving base 1 and a lifting frame 4 vertically lifted on the fixing frame 3. Two sides of the upper end of the fixing frame 3 are vertically convex with adjusting rods. Two sides of the lower end of the lifting frame 4 are recessed with slots for the adjusting rods to be inserted. A number of pin holes 7 are vertically and spacedly arranged on the adjusting rods. On the outer walls of both sides of the lifting frame 4, there are pins 5 that pass through the lifting frame 4 and are inserted into the pin holes 7. A first lead screw 8 is vertically rotatably provided on the lifting frame 4. The rotation of the first lead screw 8 is controlled by a first motor 6. A lifting slider 9 is vertically guided and moved inside the lifting frame 4. A first nut that cooperates with the first lead screw is fixed inside the lifting slider 9. The lifting slider 9 extends out of the lifting frame 4 to form a mounting seat 10. A second lead screw is rotatably provided inside the mounting seat 10. The second lead screw is controlled by a second motor. A horizontal slider is guided and slid on the mounting seat 10. A second nut that cooperates with the second lead screw is fixed inside the horizontal slider. The flipping and clamping module is fixed on the horizontal slider.

[0047] The flipping and clamping module, see Figure 3 As shown in the figure, it includes a flipping frame 11 and a clamping module. The flipping frame 11 is in a "U" shape and is welded or fixed to the horizontal slider through connecting parts such as screws at the bottom. The clamping module includes a clamping box 12 with an opening on one side. Both sides of the clamping box 12 are rotatably connected to the flipping frame 11 through rotating shafts 13. A number of groups of clamping components are circumferentially spaced on the inner circumferential wall of the clamping box 12. Each group of clamping components is axially spaced along the clamping box 12 with a number of clamping members 21 that expand and contract radially along the clamping box 12. All the clamping members 21 expand and contract synchronously and are controlled by a first electromagnetic control component.

[0048] On both sides of the flipping frame 11, a meshing gear disc 14 reciprocally moves along the axial direction of the rotating shaft 13. See Figure 4As shown, a connecting frame 15 is inserted on the flip frame 11, the connecting frame 15 is "U"-shaped and the two ends of the opening are fixedly connected to the meshing toothed disc 14, and a screw handle 16 is screwed on the end of the connecting frame 15 away from the opening. The screw handle 16 is rotatably matched with the outer wall of the flip frame 11. By rotating the screw handle 16, the meshing toothed disc 14 and the matching tooth groove can be engaged or disengaged, thereby realizing the limiting position of the clamping box 12 after the angle is adjusted relative to the flip frame 11.

[0049] Combination Figure 5 As shown, the clamping member 21 is telescopic on the inner wall of the clamping box 12 and is controlled by the second elastic member 27 to be in an elastically extended state. The first electromagnetic control component includes a first electromagnet 25 fixed in the inner wall of the clamping box 12. The two ends of the second elastic member 27 are respectively fixedly connected to the clamping member 21 and the first electromagnet 25. The clamping member 21 is made of iron and a rubber layer is fixed at its clamping end. When the first electromagnet 25 is energized, the clamping member 21 is in a retracted state; when the first electromagnet 25 is de-energized, the clamping member 21 elastically extends.

[0050] The clamping box 12 is provided with a locking assembly which can synchronously limit all the extended clamping members 21. Figures 8 - 9 As shown, the locking assembly includes a first rack 35 and a first tooth block 36. The first rack 35 is located on the outer wall of each clamping member 21 and is arranged along its extension direction. The first tooth block 36 elastically extends in the clamping box 12 and can engage or disengage with the first rack 35. The first tooth block 36 synchronously extends and is controlled by the joint cooperation of the fourth elastic member 40 and the inclined surface matching assembly. Figure 9As shown, one end of the first tooth block 36 away from the tooth surface is convexly provided with a guide rod 39 that is inserted into the clamping box 12 in a guiding manner. The inclined surface matching assembly includes a driving rod that elastically extends and retracts at the bottom of the clamping box 12. The number of driving rods is the same as the number of clamping component groups. One end of the driving rod close to the clamping box 12 includes a matching inclined block 37 corresponding to the clamping member 21 in the corresponding clamping component and an avoidance connecting rod 38 connected between adjacent matching inclined blocks 37. A first matching through groove 361 that matches the matching inclined block 37 is provided on the first tooth block 36. The fourth elastic member 40 is sleeved on the guide rod 39 and elastically abuts and cooperates with the second tooth block 30 and the inner wall of the clamping box 12. When the driving rod elastically extends, the first tooth block 36 is in a retracted state, and at this time the clamping member 21 is in an unlocked state; when the driving rod contracts, the first tooth block 36 is in an extended state, and at this time the clamping member 21 is in a locked state. Each clamping member 21 corresponds to two first tooth blocks 36 that are distributed oppositely, and the two first tooth blocks 36 are in a staggered tooth distribution state. The driving rod includes a main body rod 33 that is inserted and cooperated with the bottom of the clamping box 12 and a split rod that cooperates with the first tooth blocks 36 on both sides of the clamping member 21 at the same time. The matching inclined block 37 and the avoidance connecting rod 38 form the split rod. Such a setting can ensure that there is a first tooth block 36 that can mesh with the first rack 35, improving the locking efficiency of the clamping member 21. All the split rods and the main body rod 33 are synchronously fixed on a synchronous ring 23, and the synchronous ring 23 can ensure the synchronous operation of all the main body rods 33 and the split rods.

[0051] At the center of the bottom of the clamping box 12, a pressing and adsorbing assembly that can elastically extend and retract to adsorb the end of the insertion end of the drilling machine and limit the insertion depth is provided. See Figure 4 As shown, the pressing and adsorbing assembly includes a pressing and adsorbing mechanism and a locking mechanism. The pressing and adsorbing mechanism forms a negative pressure and adsorbs the insertion end of the drilling machine as the insertion end of the drilling machine is inserted and partially retracted. The locking mechanism restricts the movement of the pressing and adsorbing mechanism after retraction.

[0052] The pressing and adsorbing mechanism includes a fixed pipe 17 fixed at the center of the bottom of the clamping box 12 and a moving pipe 19 elastically sleeved outside the fixed pipe 17. One end of the fixed pipe 17 away from the opening end of the clamping box 12 is provided with an exhaust valve (not shown) that exhausts air unidirectionally outward. The exhaust valve is an existing structure and has not been improved, and its specific structure will not be elaborated here. A gas supplementing member 18 that can open and close the internal air cavity of the fixed pipe 17 is screwed on the fixed pipe 17; the locking mechanism includes a second rack 191 and a second tooth block 30. Combining Figure 7As shown, the second rack 191 is located on the outer wall of the moving tube 19 and extends along the axial direction of the moving tube 19. The number of sets of the second rack 191 and the second tooth blocks 30 is the same as that of the clamping assemblies, both being four sets. The second tooth blocks 30 are elastically telescoped in the clamping box 12 under the driving of the third elastic member 32 and the second electromagnet 31 and can engage or disengage with the second rack 191. The second electromagnet 31 is fixed inside the clamping box 12. Both ends of the third elastic member 32 are fixedly connected to the second tooth block 30 and the second electromagnet 31 respectively. The second tooth blocks 30 are made of iron.

[0053] The telescoping of the driving rod is controlled by the telescoping of the second tooth block 30. The second tooth block 30 is vertically inserted and matched with the main body rod 33. A second fitting through groove 34 is provided on the main body rod 33. The second tooth block 30 is provided with a pressing inclined surface 3001 that cooperates with the second fitting through groove 34. A fifth elastic member 44 connected to the main body rod 33 is provided in the clamping box 12. When the second electromagnet 31 loses power, the second tooth block 30 extends, and the pressing inclined surface 3001 presses the second fitting through groove 34 and drives the main body rod 33 to retract; when the second electromagnet 31 is powered on, the second tooth block 30 retracts, and the main body rod 33 elastically extends under the driving of the fifth elastic member 44. The above structure enables the movement of the driving rod to be linked with the movement of the second tooth block 30, and thus the synchronous limiting of all the clamping members 21 and the moving tube 19 can be controlled by the power-on or power-off of the second electromagnet 31. This design can significantly reduce the difficulty of circuit layout, reduce the number of sets of electromagnets, and reduce the space occupied by redundant components.

[0054] An air path control assembly is provided between the clamping member 21 and the clamping box 12. Combining Figures 4 - 6 As shown, the air path control assembly can synchronously realize the independent change of the air pressure of each clamping member 21. The air path control assembly includes an independent air path assembly and an air extraction assembly. The independent air path assembly includes a first air groove 24 provided in each clamping member 21, a plurality of second air grooves at the bottom of the clamping box 12 that are independently connected to a first air groove 24, and a connecting hose 26 connecting the first air groove 24 and the second air groove; the air extraction assembly includes a piston plate 28 and a piston rod 281 that is hermetically moved in the second air groove. All the piston rods 281 are synchronously connected to the piston plate 28. The piston plate 28 is movably sealed in the first fitting cavity. All the piston plates 28 are synchronously connected to a moving plate 29. The movement of the moving plate 29 is controlled by a cylinder 22 built in the clamping box 12. The end of the piston rod of the cylinder 22 is fixedly connected to the moving plate 29.

[0055] The first elastic member 20, the second elastic member 27, the third elastic member 32, the fourth elastic member 40, and the fifth elastic member 44 are all springs. The magnitude of the elastic force between the above springs can be selected according to actual needs. The electromagnetic air control valve of the air cylinder 22, the first motor 6, the second motor, the first electromagnet 25, and the second electromagnet 31 are all connected to the PLC. A touch screen (not shown) connected to the PLC is installed on the fixed frame 3. The operator can issue commands such as opening and closing of the first electromagnet 25 and the second electromagnet 31, switching of the electromagnetic air control valve of the air cylinder 22, forward and reverse switching of the first motor 6 and the second motor 6, and opening and closing on the touch screen. Implementing the opening and closing and switching commands of the above components by the PLC through the operation of the touch screen is prior art and will not be elaborated here.

[0056] Operation steps:

[0057] 1. Clamping the drilling machine:

[0058] 1.1 Initial state: The first electromagnet 25 is in the energized state, and the second electromagnet 31 is in the energized state. At this time, the first tooth block 36, the second tooth block 30, and the clamping member 21 are all in the retracted state, and the piston rod 281 of the air cylinder 22 is in the extended state;

[0059] 1.2 Clamping: Insert the part to be clamped (lower end handle or tail handle) of the handheld drilling machine through the opening of the clamping box 12. After the insertion end of the drilling machine presses against the moving tube 19 and moves inward to the maximum insertable position and then retreats outward by 1 / 5 to 1 / 3 of the insertion stroke, it is appropriate that the operator can feel the negative pressure at the insertion end of the drilling machine. At this time, first de-energize the first electromagnet 25, and the clamping member 21 elastically extends and clamps on the outer wall of the insertion end of the drilling machine. Then, de-energize the second electromagnet 31, and the second tooth block 30 extends to limit the movement of the moving tube 19. The extension of the second tooth block 30 drives the drive rod to retreat. The second tooth block 30 extends and meshes with the first rack 35 on the clamping member 21 to limit the movement of the clamping member 21. Finally, drive the piston rod 281 of the air cylinder 22 to retract, and the negative pressure at the contact part between the clamping member 21 and the drilling machine increases to achieve adsorption;

[0060] 1.3 Drilling machine angle adjustment: Rotate the screw handle 16 to first disengage the meshing tooth disc 14 from the mating tooth groove, rotate the clamping box 12 until the drill bit of the drilling machine is in a horizontal or vertically upward state (adjust according to the drilling position), and then rotate the screw handle 16 in the reverse direction until the meshing tooth disc 14 meshes with the mating tooth groove again;

[0061] 2. Movement and limitation of the moving bracket: Push the moving bracket to the vicinity of the position where drilling is required. First, rotate the first height adjustment handle 42 to achieve elastic pressing of the suction cup 41 against the ground; then rotate the second height adjustment handle 43 to move the piston member upward, so that the negative pressure at the contact between the suction cup 41 and the ground continuously increases until it firmly adheres to the ground;

[0062] 3. Maximum moving stroke adjustment: Adjust the position of the latch pin 5 according to the actual height;

[0063] 4. Drilling: Turn on the start button on the drilling machine. Then, start the first motor 6. After the mounting seat 10 rises to the required drilling height, turn off the first motor 6. Start the second motor 6 to make the moving base 1 carry the drilling machine to move to the drilling position and perform drilling. After drilling, switch the second motor 6 to reverse to disengage from the wall. Then switch the first motor 6 to reverse to make the mounting seat 10 descend to the maximum stroke, turn off the drilling machine, and finally, release the adsorption of the suction cup 41. At this time, the drilling machine is still in the clamped state, waiting for the next wall drilling. If it is necessary to replace or remove the drilling machine, first make the second electromagnet 31 energized, then make the piston rod 281 of the cylinder 22 extend. Further, make the first electromagnet 25 energized. Finally, the air replenishing part 18 is opened for air replenishment. The drilling machine automatically disengages outward under the action of the restoring force of the first elastic member 20 between the moving pipe 19 and the fixed pipe 17. The operator only needs to hold the drilling machine to easily take it out.

[0064] During the drilling process, the operator should hold the lifting frame 4 to further limit the movement of the moving bracket.

[0065] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
