[0002] During the construction process, in order to enhance the building's bearing capacity, improve its seismic resistance and extend its service life, steel bars are implanted in the concrete structure for reinforcement. During the process of implanting steel bars, the workers will first drill holes at the selected locations. After the drilling is completed, the workers are also required to clean the dust and debris in the holes to ensure the firmness of the steel bar connection process.

[0003] At present, the workers will complete the hole cleaning work by cooperating with a high-pressure air gun and a brush. During the hole cleaning process, the workers will hold the air gun in one hand and the brush with the other hand, and then use the high-pressure air gun to blow out the debris in the drill hole. Then use the other hand to insert the hole cleaning brush into the drill hole, and manually rotate the brush several times and then pull it out to take out the debris remaining in the drill hole. Since the entire area of ​​the building is large, the number of drill holes is relatively large, that is, the workers need to repeatedly rotate the brush, which will increase the labor intensity of the workers. To this end, we propose a hole cleaning device for engineering construction to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 , a hole cleaning device for engineering construction, including a handle 1, the end of the handle 1 is connected to an air supply pipe 2, the connection relationship and working principle of the handle 1 and the air supply pipe 2 are prior art, which will not be described in detail here. The upper side of the handle 1 is connected to a support frame 3, and a motor 4 is provided on the inner side of the support frame 3, and a rotating shaft 5 is provided at the output end of the motor 4, and brushes 15 are evenly distributed on the outer side of the rotating shaft 5. When in use, the support of the motor 4 can be achieved by the setting of the support frame 3, and the rotating shaft 5 and the brush 15 can be driven to rotate continuously by the drive of the motor 4, so that the staff does not need to manually rotate the brush 15.

[0023] Further, refer to Figure 3 It can be seen that the end movable sleeve of the rotating shaft 5 is provided with a connecting sleeve 13, and the side of the connecting sleeve 13 is fixedly connected to the output end of the motor 4, and threaded rods 14 are respectively inserted into the connecting sleeve 13 and the rotating shaft 5, and the top of the threaded rod 14 is connected to a rotating block 16. When in use, the rotating shaft 5 and the connecting sleeve 13 can be disassembled by the mutual cooperation of the connecting sleeve 13 and the threaded rod 14, so that the staff can easily remove the brush 15 that has reached the end of its service life, and the brush 15 of appropriate specifications can be installed according to the diameter of the drill hole.

[0024] Further, refer to Figure 3 and Figure 4 It can be seen that a connecting ring 6 is provided on the outer side of the motor 4, and rotating rods 7 are symmetrically connected to the two ends of the connecting ring 6. The outer wall of the rotating rod 7 is connected to the support frame 3 through a bearing, thereby effectively ensuring the stability of the connecting ring 6 during rotation. The side of the rotating rod 7 away from each other passes through the inner wall of the support frame 3 and is connected to a rotating disk 8, and a rectangular frame 9 is provided on the periphery of the rotating disk 8. The rectangular frame 9 is connected to the outer wall of the support frame 3, and the upper and lower ends of the rectangular frame 9 are symmetrically inserted with limit rods 11, and the side of the limit rod 11 away from each other is connected to a pull bar 10. The interior of the rotating disk 8 is provided with four groups of card slots compatible with the limit rods 11. When in use, the opening of the four groups of card slots can facilitate the staff to limit the connecting ring 6 that is turned to the horizontal and vertical states.

[0025] Further, refer to Figure 3 and Figure 4It can be seen that the pull bar 10 is set to a U-shaped structure, and the pull bar 10 is distributed at the left side of the support frame 3. When in use, the pull bar 10 set by the U-shaped structure can facilitate the staff to simultaneously pull the two groups of pull bars 10 closer or away from each other, and since the pull bar 10 is distributed on the left side of the support frame 3, the normal rotation of the connecting ring 6 and the motor 4 can be guaranteed.

[0026] Further, refer to Figure 4 It can be seen that springs 12 are symmetrically distributed on both sides of the limit rod 11, and one end of the spring 12 is connected to the rectangular frame 9, and the other end of the spring 12 is fixedly connected to the pull bar 10. When in use, the spring 12 connected between the pull bar 10 and the rectangular frame 9 can effectively ensure the reliability of the limit rod 11 being engaged in the internal slot of the rotating disk 8.

[0027] Further, refer to Figure 3 It can be seen that rectangular blocks are symmetrically connected to both ends of the rotating block 16, and anti-slip particles are evenly distributed on the outer surface of the rectangular block. Through the mutual cooperation between the rectangular blocks and the anti-slip particles, it is convenient for the staff to rotate the rotating block 16, so that the staff can quickly pull the threaded rod 14 out from the inside of the connecting sleeve 13 and the rotating shaft 5.

[0028] Further, refer to Figure 1 and Figure 2 It can be seen that the bottom end of the left side of the support frame 3 is connected to a mounting plate, and the inside of the mounting plate is connected to the handle 1 through bolts. By setting the mounting plate, the support frame 3 and the handle 1 can be docked. When the handle 1 is damaged, the staff will install the support frame 3 on a new set of handles 1 for use.

[0029] Working principle: When the utility model is in use, the staff can first pull the two sets of pulling bars 10 to move in opposite directions, thereby driving the upper and lower distributed limit rods 11 to be forced to move away from each other at the same time, and the limit rods 11 will be pulled out from the inside of the rotating disk 8, thereby releasing the limit on the two sets of rotating disks 8. At this time, the staff can rotate the rotating shaft 5, so that it can be forced to rotate ninety degrees and keep it vertical to the air supply pipe 2. After the rotation of the air supply pipe 2 is completed, the staff can stop pulling the two sets of pulling bars 10, so that each set of limit rods 11 is forced to be embedded in the corresponding card slots opened inside the rotating disk 8, so as to realize the limit work of the rotating shaft 5 and the motor 4. When cleaning, the staff can first align the air supply pipe 2 with the drill hole, and then squeeze the handle 1 to blow away the debris in the drill hole. After completing the hole blowing operation, the staff can insert the brush 15 into the drill hole, and then start the motor 4 to drive the rotating shaft 5 and the brush 15 to rotate continuously, so as to further clean the drill hole. After the cleaning is completed, the staff can pull the brush 15 out of the drill hole and stop the drive of the motor 4. After completing the hole cleaning work, the staff can pull the two sets of pull bars 10 again, so as to realize the storage work of the rotating shaft 5 and the brush 15. The above is the entire working principle of the present utility model.
