Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] The existing drilling cuttings cleaning device has the technical problems of limited effect on cleaning the waste cuttings on the hole wall, affecting the stability and safety of the reinforcement, and low efficiency.

[0038] In view of this, the utility model provides a masonry structure drilling cleaning device, comprising: a mounting frame 100, a rotating tube 200 and a nozzle 300. The hollow tube 210 is rotatably connected to the mounting frame 100, and the brush cylinder 220 is installed at one end of the hollow tube 210. The hollow tube 210 can rotate around its own axis to drive the brush cylinder 220. The nozzle 300 is inserted into the rotating tube 200 and connected to the air pump for blowing air into the drilled hole.

[0039] Based on the above technical solutions, the masonry structure drilling and cleaning device provided by the utility model can achieve the following technical effects:

[0040] The masonry structure drilling cleaning device combines a mechanical brush with an air jet to effectively remove debris attached to the hole wall, improve the cleaning quality, ensure the reliability of the reinforcement, and improve the cleaning speed and ease of operation. It overcomes the problems of the existing drilling cleaning device, which has limited cleaning effect on the waste debris on the hole wall, affects the stability and safety of the reinforcement, and has low efficiency.

[0041] The following combination Figures 1 to 4The structure and shape of the masonry structure drilling and cleaning device provided in this embodiment are described in detail:

[0042] In the solution of this embodiment, Figure 1 As shown, the mounting frame 100 is provided with a protective shell 110, a handle 120 and a support frame 130. The protective shell 110, the handle 120 and the support frame 130 are all arranged at the end of the mounting frame 100 away from the brush cylinder 220. The protective shell 110 is used to protect the internal components from damage by the external environment, and the handle 120 is used for the construction personnel to hold the entire device. The support frame 130 is fixedly connected to the nozzle 300 to improve the installation stability of the nozzle 300.

[0043] In order to further enhance the cleaning effect of the cleaning device on impurities on the hole wall, in the preferred scheme of this embodiment, the rotating tube 200 is set as an eccentric structure, the axis of the brush tube 220 does not coincide with the axis of the hollow tube 210, and the brush tube 220 makes eccentric movement relative to the drill hole. When the brush tube 220 rotates, it will produce an extrusion and scraping effect on the hole wall.

[0044] In the optional solution of this embodiment, Figure 1 As shown, the brush cylinder 220 is configured as an eccentric wheel structure, the axis of the brush cylinder 220 does not coincide with the axis of the hollow tube 210, and the brush cylinder 220 performs eccentric motion with the rotation of the hollow tube 210 to produce an extrusion and scraping effect on the hole wall, thereby enhancing the cleaning effect on impurities on the hole wall.

[0045] In an optional scheme of this embodiment, the hollow tube 210 is set as an eccentric shaft, the eccentric shaft is set as a hollow shaft, the rotation axis of the hollow tube 210 does not coincide with its own axis, the brush cylinder 220 is a concentric wheel, the brush cylinder 220 is connected to the eccentric section of the hollow tube 210, and the brush cylinder 220 performs eccentric movement with the eccentric rotation of the hollow tube 210 to produce an extrusion and scraping effect on the hole wall, thereby enhancing the cleaning effect of impurities on the hole wall.

[0046] The solution of this embodiment further includes a driving mechanism 400 , which is installed on a fixing frame provided at one end of the mounting frame 100 and is connected to the hollow tube 210 for driving the hollow tube 210 to rotate so as to drive the brush cylinder 220 to rotate.

[0047] In the optional solution of this embodiment, Figure 2 As shown, the driving mechanism 400 includes a motor 410, a first gear 420 and a second gear 430. The motor 410 is mounted on the mounting frame 100, the first gear 420 is mounted on the output end of the motor 410, the second gear 430 is sleeved on the hollow tube 210 and meshed with the first gear 420, and the power of the motor 410 is transmitted to the hollow tube 210 through the meshing of the first gear 420 and the second gear 430.

[0048] In the optional scheme of this embodiment, the driving mechanism 400 includes an air motor, a control valve and a guide tube. The air motor is mounted on the mounting frame 100 and connected to the hollow tube 210, and is used to drive the hollow tube 210 to rotate. One end of the control valve is connected to the air pump, and the other end is connected to the air inlet of the air motor, and is used to control the air motor. One end of the guide tube is connected to the exhaust port of the air motor, and the other end is connected to the nozzle 300, and is used to collect the gas discharged from the air motor into the nozzle 300, so as to recycle the gas discharged from the air motor.

[0049] In order to prevent drilling cuttings or dust from entering the nozzle 300, the solution of this embodiment further includes a sealing mechanism 500, such as Figure 4 As shown, the sealing mechanism 500 is installed at the air outlet of the nozzle 300. The sealing mechanism 500 includes a first baffle 510, a movable rod 520, a second baffle 530, a third baffle 540 and a spring 550. The first baffle 510 is arranged in the nozzle 300 and is fixedly connected to the nozzle 300. The movable rod 520 is inserted into the first baffle 510 and is slidably connected to the first baffle 510. One end of the movable rod 520 is connected to the second baffle 530 and the other end is connected to the third baffle 540. One end of the spring 550 abuts against the first baffle 510 and the other end abuts against the second baffle 530, and is used to apply a thrust to the second baffle 530 so that the third baffle 540 closes the air outlet of the nozzle 300. When gas in the nozzle 300 hits the third baffle 540, the air outlet of the nozzle 300 is exposed, so that air is blown into the borehole to blow out the waste or impurities in the borehole. When the third baffle plate 540 moves, the second baffle plate 530 is driven by the rod 520 to move toward the third baffle plate 540, and the spring 550 is contracted. When the nozzle 300 is not in use, the spring 550 is extended and reset and drives the third baffle plate 540 to close the air outlet of the nozzle 300 again.

[0050] In summary, the specific working process of the drilling and cleaning device for masonry structures provided in this embodiment is as follows:

[0051] The construction worker grasps the cleaning device by the handle 120, places the brush cylinder 220 in the borehole, and then drives the hollow tube 210 through the driving mechanism 400 to drive the brush cylinder 220 to rotate. Due to the eccentric configuration of the brush cylinder 220, the brush cylinder 220 makes an eccentric movement in the borehole to continuously scrape the waste on the borehole wall. The hollow tube 210 is pulled back and forth to make the brush cylinder 220 move forward and backward in the borehole. While the brush cylinder 220 is working, the air pump inputs gas into the nozzle 300, and the gas in the nozzle 300 impacts the third baffle 540, thereby exposing the air outlet of the nozzle 300, blowing air into the borehole to blow out the waste or impurities in the borehole, and when the third baffle 540 moves, the second baffle 530 will be driven by the passive rod 520 to move toward the third baffle 540 side, and the spring 550 will shrink. After cleaning is completed, the air pump is turned off, the spring 550 will be extended and reset and drive the third baffle 540 to close the air outlet of the nozzle 300 again.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
