Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and in particular relates to a wall drilling device. Background Art
[0002] Urban development is progressive, so old houses still account for a considerable proportion in urban construction. These old houses usually adopt brick-concrete structures. After long-term use and erosion by the natural environment, the wall structure gradually ages and is damaged, and it is easy to have problems such as wall cracking and tilting. It does not meet the requirements of earthquake resistance standards, which seriously affects the overall safety and service life of the building. In order to improve the earthquake resistance and safety of old houses, they need to be reinforced.
[0003] In the process of reinforcing old houses, common reinforcement methods include painting high-strength mortar, adding structural columns and ring beams, and adding wire mesh concrete surface layers. The above reinforcement technologies all have their limitations, and they all require home reinforcement, which will bring about problems in the early resettlement of residents. It takes a long time to persuade residents, which increases the time cost and resettlement cost. In order to avoid some problems caused by home reinforcement, it is necessary to drill vertical holes from the top of the wall to the ground foundation. Since the drilling of the wall of the house is different from the drilling of other structures, water cannot be used to assist the drilling. Utility Model Content

[0041] like Figure 10-12 As shown, the collecting assembly 4 includes a negative pressure pump 41, a hose 42, a collecting box 43, and a nozzle 45.

However, this method will affect the safety of the staff around the frame. This embodiment is preferred to the negative pressure pump 41 and the collection box 43.
[0042] The usage and principle of this embodiment are as follows:
[0043] The first step: align the through hole 121 of the fixed plate with the position where the hole needs to be drilled on the horizontal surface of the wall, control the generator to generate electricity through the controller, and control the output shaft of the first servo motor 22 to rotate, driving the second gear 24 to rotate, the second gear 24 drives the first gear 23 to rotate, and the first gear 23 drives the drill rod assembly 3 to rotate. The controller controls the output shaft of the second servo motor 25 to rotate and drive the screw 26 to rotate. The screw 26 is threadedly connected to the sliding plate 21, so that the sliding plate 21 can slide up and down in the U-shaped plate groove 111, and the drill rod assembly 3 rises and falls with the screw 26.
[0044] Step 2: In this embodiment, the output shaft of the first servo motor 22 rotates clockwise to drill holes, and the output shaft of the first servo motor 22 rotates counterclockwise to withdraw the drilling tool; the output shaft of the second servo motor 25 rotates clockwise to raise the sliding plate 21, and the output shaft of the second servo motor 25 rotates counterclockwise to lower the sliding plate 21. During the drilling process, the circular drill rod 32 is increased or decreased according to the depth of the drilling.
[0045] When adding a round drill rod 32, the output shaft of the second servo motor 25 is controlled by the controller to rotate, and the round drill rod groove 322 closest to the square drill rod 31 is moved to the fixed plate through hole 121. The round drill rod groove 322 is clamped with the help of a tool, and the output shaft of the first servo motor 22 is controlled by the controller to rotate counterclockwise, and the output shaft of the second servo motor 25 is controlled to rotate clockwise, so that the square drill rod 31 and the round drill rod 32 are separated, and the output shaft of the second servo motor 25 is controlled by the controller to rotate clockwise, and the sliding plate 21 rises to a suitable position, and a round drill rod 32 is added between the square drill rod 31 and the round drill rod 32. The output shaft of the first servo motor 22 is controlled by the controller to rotate clockwise, and the second servo motor 25 is controlled to rotate counterclockwise, so that the round drill rod 32 is added.
[0046] When reducing the circular drill rod 32, the output shaft of the second servo motor 25 is controlled by the controller to rotate, the second nearly circular drill rod groove 322 away from the square drill rod 31 is moved to the fixed plate through hole 121, the circular drill rod groove 322 is clamped by means of a tool, the output shaft of the first servo motor 22 is controlled by the controller to rotate counterclockwise, and the output shaft of the second servo motor 25 is controlled to rotate clockwise, and the circular drill rod 32 closest to the square drill rod 31 is clamped by means of a tool, so that the circular drill rod 32 closest to the square drill rod 31 is separated from the square drill rod 31 and the second nearly circular drill rod 32 away from the square drill rod 31, the output shaft of the second servo motor 25 is controlled by the controller to rotate counterclockwise, the sliding plate 21 is lowered to a suitable position, and the output shaft of the first servo motor 22 is controlled clockwise to thread the circular drill rod 32 and the square drill rod 31, so as to reduce the circular drill rod 32;
[0047] When drilling the wall, the drill bit uses a crushing drill bit 33 and a hollow drill bit 34. The hollow drill bit 34 first contacts the wall to achieve core drilling. When the crushing drill bit 33 contacts the waste residue in the wall, it is crushed and enters the circular drill rod 32. Because there are steel bars in the wall, when drilling the steel bars in the wall, the drill bit uses a tungsten steel drill bit, and the waste residue drilled by the tungsten steel drill bit enters the circular drill rod 32. In the process of the circular drill rod 32 rotating and descending, the waste residue is squeezed upward and the centrifugal force of the rotation is used to realize the vertical transportation of the waste residue, and is transported from the drill bit to the top of the drill rod.
[0048] During the drilling process, if the difference between the detection values of the two distance sensors 28 is greater than the set value, the distance sensor 28 outputs an electrical signal to the controller, and the controller controls the output shaft speed of the second servo motor 25 to speed up or slow down. In this embodiment, the distance sensor 28 close to the negative pressure pump 81 is the first distance sensor, and the distance sensor 28 close to the screw 26 is the second distance sensor; during the ascending process, the detection value of the first distance sensor is greater than the detection value of the second distance sensor and the difference is greater than the set value, and the controller controls the output shaft speed of the second servo motor 25 to slow down; during the descending process, the detection value of the first distance sensor is greater than the detection value of the second distance sensor and the difference is greater than the set value, and the controller controls the output shaft speed of the second servo motor 25 to speed up; during the ascending process, the detection value of the first distance sensor is less than the detection value of the second distance sensor and the difference is greater than the set value, and the controller controls the output shaft speed of the second servo motor 25 to speed up; during the descending process, the detection value of the first distance sensor is less than the detection value of the second distance sensor and the difference is greater than the set value, and the controller controls the output shaft speed of the second servo motor 25 to slow down.
[0049] Step 3: The negative pressure pump 41 is started by the controller. Under the negative pressure generated by the negative pressure pump 41, the drill rod and the drill bit can be cooled and the waste residue in the drill rod can be discharged more easily. The waste residue enters the collection box 43 through the hose 42. The isolation plate 44 divides the collection box 43 into two areas: waste residue and floating dust. Larger waste residue remains in the waste residue area of the collection box 43, and floating dust enters the floating dust area of the collection box 43 through the filter hole 441. When it reaches the exhaust port, the nozzle 45 sprays water mist to make the floating dust in the collection barrel sink. The first slag removal door 46 discharges larger waste residue, and the second slag removal door 47 discharges floating dust to achieve classified treatment.
