A connecting mechanism 37 is provided;

[0027] When the auxiliary bracket is in use, the side support rod 36 is installed on the connecting seat 35 through the connecting mechanism 37, and the main support rod 2 can be supported by the side support rod 36. By starting the transmission motor 31, the threaded rod 32 can be driven to rotate, and the threaded sliding rod 33 can be driven to slide along the guide column 34, so that the side support rod 36 can be driven to rotate through the connecting seat 35, and the main support rod 2 can produce corresponding rotation, which is convenient for adjusting the angle of the auxiliary bracket. When in use, the cable in the pay-off mechanism 4 will first pass through the wire rack 5, and then be connected to the impact drill bit under the guidance of the anti-shake mechanism 7 and the wire roller 6. Through the pay-off of the pay-off mechanism 4, the impact drill bit can impact the foundation pile.

[0028] like Figure 3 As shown, the utility model provides an auxiliary support for pile impact drilling in construction, the connecting mechanism 37 includes a fixing bolt 371 and a threaded sleeve 372, the fixing bolt 371 is movably connected to the upper side of the side support rod 36 away from the connecting seat 35, a sliding groove 2 is opened on the upper side of the side support rod 36 close to the connecting seat 35, the threaded sleeve 372 is slidably connected inside the sliding groove 2, one end of the fixing bolt 371 close to the side support rod 36 penetrates into the inside of the sliding groove 2 and the outer surface is threadedly connected to the inner surface of the threaded sleeve 372, the side of the threaded sleeve 372 close to the connecting seat 35 is fixedly connected to a fixing platform 373, the outer surface of the fixing platform 373 is fixedly connected to a bearing 374, and the bearing 374 is fixedly connected to the side of the connecting seat 35 close to the side support rod 36;

[0030] like Figure 4-5As shown, the utility model provides an auxiliary support for pile impact drilling in construction, the anti-shake mechanism 7 includes a sliding guide rod 71, a sliding groove 3 is opened at the lower right side of the main support rod 2, the sliding guide rod 71 is fixedly connected to the inside of the sliding groove 3, a sliding block 72 is slidably connected to the middle part of the outer surface of the sliding guide rod 71, and a wire management box 74 is fixedly connected to the right end of the sliding block 72. Buffer springs 73 are arranged on both upper and lower sides of the outer surface of the sliding guide rod 71, and the two buffer springs 73 are respectively fixedly connected to the upper and lower sides of the sliding block 72. The wire management box 74 has upper and lower through holes opened inside. The guide groove is penetrated, and sliding frames 741 are arranged on the left and right sides of the inner surface of the guide groove. The opposite surfaces of the two sliding frames 741 are movably connected with two rollers 742. The left sliding frame 741 is fixedly connected to the left side of the inner surface of the guide groove, and the right sliding frame 741 is slidably connected to the right side of the inner surface of the guide groove. The right side of the right sliding frame 741 is fixedly connected with a threaded slide post 743, and the inner surface of the threaded slide post 743 is threadedly connected with a threaded rod 2 744. The right end of the threaded rod 2 744 passes through the right surface of the wire management box 74 and is fixedly connected with a knob 745.

[0031] When the impact drill is in use, the cable will pass through the guide groove in the cable management box 74. When the auxiliary bracket vibrates, the sliding block 72 will squeeze the buffer spring 73. The elastic line of the buffer spring 73 allows the sliding block 72 to slide repeatedly along the sliding guide rod 71, thereby driving the cable management box 74 to slide repeatedly, and can comb the cables in the impact drill through the roller 742, thereby reducing the jitter amplitude of the impact drill cable and avoiding affecting the use of the impact drill. At the same time, by rotating the knob 745, the threaded rod 744 can drive the threaded sliding column 743 to slide, thereby driving the sliding frame 741 on the right to slide, which facilitates the adjustment of the distance between the rollers 742 on both sides and the combing of cables of different sizes, making the use of the impact drill more convenient.

[0032] The working principle of the auxiliary bracket of the impact drill for building construction foundation piles is described in detail below.

[0033] like Figure 1-5As shown, when the auxiliary bracket is in use, the transmission motor 31 can drive the threaded rod 32 to rotate, and can drive the threaded sliding rod 33 to slide along the guide column 34, so that the side support rod 36 can be driven to rotate through the connecting seat 35, and the main support rod 2 can produce corresponding rotation, which is convenient for adjusting the angle of the auxiliary bracket. When in use, the cable in the wire-releasing mechanism 4 will first pass through the wire rack 5, and then be connected to the impact drill bit under the guidance of the anti-shake mechanism 7 and the wire roller 6. Through the wire-releasing mechanism 4, the impact drill bit can impact the foundation pile. At the same time, the sliding block 72 slides on the outer surface of the sliding guide rod 71, so as to drive the wire management box 74 to slide, which is convenient for combing the cables in the impact drill through the roller 742, avoiding the cable from shaking drastically when the impact drill is in use, making the use of the impact drill more convenient.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
