Description

Technical Field

[0001] This utility model belongs to the field of masonry wall reinforcement technology, and in particular relates to a drilling device for masonry wall reinforcement. Background Technology

[0002] Due to lower construction standards, aging materials, and frequent alterations and additions during use, the safety hazards of early masonry wall structures are increasing. Therefore, reinforcing early masonry wall structures and extending their service life is currently a hot research topic.

[0003] In the reinforcement process of masonry wall structure houses, it is usually necessary to drill holes in the masonry wall to provide a location for the installation of reinforcement materials (such as steel bars, anchor rods, chemical anchors, etc.). In the existing reinforcement construction technology, the drilling device is generally operated by the construction personnel directly by hand, which has the following disadvantages: (1) Inconvenience of use: In the reinforcement process, it is often necessary to drill holes at multiple different heights. The construction personnel can only adjust their posture up and down according to the drilling position in order to adjust their body height to keep it consistent with the height of the target drilling device; (2) Poor applicability: In the reinforcement process, it is not only necessary to drill holes facing the masonry wall directly in front, but sometimes it is also necessary to drill holes in the roof and ground of the masonry wall house (such as the middle floor of a multi-story masonry wall structure house). The construction personnel can only frequently use external force to lift or bend over to carry out the drilling work. Long-term hand-held work will cause physical burden to the personnel; (3) Poor stability: Poor hand-held stability may cause the drilling to tilt or deviate, affecting the drilling quality. Utility Model Content

The moving block is threadedly connected to the corresponding lead screw. The drilling mechanism is located above the base plate and is positioned between the two moving blocks.

[0007] Preferably, the drilling mechanism includes two second motors, two slip rings, a sliding frame, a mounting plate, and drilling equipment. The sliding frame is U-shaped, and the mounting plate is rectangular. The two second motors are respectively fixedly installed at the ends of the two moving blocks that are close to each other. The sliding frame is parallel to the top of the base plate with the U-shaped opening facing forward. The two slip rings are respectively slidably sleeved on the left and right sides of the sliding frame. At the same time, the two slip rings are respectively fixedly connected to the output shaft of the corresponding second motor. The left and right ends of the rear side of the mounting plate are respectively fixedly installed at the front ends of the left and right sides of the sliding frame.

[0010] Preferably, in order to facilitate the operation of the sliding frame, mounting plate and drilling equipment to move back and forth, a handle is fixedly installed at the bottom of the horizontal frame of the sliding frame.

[0011] Preferably, in order to facilitate automated operation of the drilling device, the drilling device also includes a controller and a remote controller. The controller is mounted on the base plate and is electrically connected to the electric slide rail, the first motor, the second motor and the drilling equipment, respectively. The remote controller is wirelessly connected to the controller.

[0012] Preferably, in order to improve the flexibility of the drilling device, the base plate is rectangular, and omnidirectional wheels are fixedly installed at the four corners of its bottom.

[0013] In order to improve the stability of the electric slide rails, a reinforcing plate is fixedly installed between the rear side of the two electric slide rails and the base plate. The longitudinal section of the reinforcing plate is a right triangle. One vertical side of the reinforcing plate is fixedly installed on the rear side of the electric slide rail, and the other vertical side is fixedly installed on the top of the base plate.

[0015] Beneficial effects:

[0016] 1. To solve the problem of inconvenient use of drilling equipment, a base plate is used to stably support two electric slide rails. Activating the electric slide rails enables the transmission box and drilling mechanism to perform the first height adjustment (coarse adjustment). Furthermore, by activating the first motor, the lead screw is rotated. At this time, through the threaded connection between the lead screw and the moving block, the moving block and drilling mechanism can perform a second height adjustment (fine adjustment). Therefore, this utility model eliminates the need for manual vertical adjustment. By simply controlling the electric slide rails and the first motor, the combined coarse and fine adjustments can be made to adjust the drilling height according to the required height, improving ease of use.

[0017] 2. To facilitate drilling operations on masonry walls in different locations, a sliding frame can be pushed by personnel to move the mounting plate and drilling equipment back and forth. When the drilling equipment moves forward, it can contact the masonry wall and perform drilling operations at the drilling points. In addition, starting the second motor can drive the slip ring to rotate. When the slip ring rotates, it can drive the sliding frame, mounting plate, and drilling equipment to rotate. When the drilling equipment rotates downward, it can drill through a rectangular hole in the masonry wall floor. When the drilling equipment rotates upward, it can drill through the masonry wall roof, thereby improving the convenience and applicability of drilling masonry walls.

[0018] 3. During the drilling process of this utility model, there is no need for personnel to hold the drilling equipment. The drilling equipment has good stability, high drilling quality, and reduces the physical burden on personnel.

[0019] In summary, this utility model achieves stable support for drilling equipment through a simple structure, while facilitating the movement, height adjustment, and rotation adjustment of the drilling equipment. It enables drilling operations on different surfaces of masonry walls, and eliminates the need for manual operation, saving time and effort and demonstrating strong practicality.

The rear sides of the two electric slide rails 4 are flush with the base plate. A reinforcing plate 5 is fixedly installed between each of the base plates 1 and 2. The longitudinal section of the reinforcing plate 5 is a right-angled triangle. One vertical side of the reinforcing plate 5 is fixedly installed on the rear side of the electric slide rail 4, and the other vertical side is fixedly installed on the top of the base plate 1. The transmission box 6 is slidably installed on the front side of the corresponding electric slide rail 4, and the open sides of the two transmission boxes 6 are arranged facing each other. The lead screw 8 is built into the corresponding transmission box 6, and its bottom end is rotatably connected to the inner bottom wall of the corresponding transmission box 6. The first motor 7 is fixedly installed on the top of the corresponding transmission box 6, and the output shaft of the first motor 7 passes through the top wall of the transmission box 6 and is fixedly connected to the top end of the corresponding lead screw 8. The moving block 9 is screwed into the base plate 1. The threaded sleeve is connected to the corresponding lead screw 8; the drilling mechanism includes two second motors 10, two slip rings 11, a sliding frame 12, a mounting plate 13, and a drilling device 14. The sliding frame 12 is U-shaped, and the mounting plate 13 is rectangular; the two second motors 10 are respectively fixedly installed on the two moving blocks 9 at their respective close ends; the sliding frame 12 is parallel to the top of the base plate 1 with the U-shaped opening facing forward, and a handle 17 is fixedly installed at the bottom of the horizontal frame of the sliding frame 12; the two slip rings 11 are respectively slidably sleeved on the left and right sides of the sliding frame 12, and both slip rings 11 are respectively fixedly connected to the output shaft of the corresponding second motor 10; the mounting plate 14 is also fixedly connected to the corresponding second motor 10. The left and right ends of the rear side of 3 are respectively fixedly installed on the front end of the left and right sides of the sliding frame 12. Springs 16 are respectively sleeved on the left and right sides of the sliding frame 12.
