[0031] The following is combined with Figure 1-2 The specific implementation methods of the present utility model are further described.

[0032] like Figure 1 As shown, an auxiliary device for drilling holes for embedding reinforcement at the bottom of a beam comprises a horizontally arranged base plate 1, on the surface of which a telescopic rod 3 is fixedly mounted. In this embodiment, the telescopic rod 3 is an electric telescopic rod 3; the telescopic rod 3 is vertically mounted on the base plate 1, and a mounting base 4 is connected to the upper end of the telescopic rod 3, on which an electric drill 5 is mounted. The electric drill 5 completes the drilling of the embedding reinforcement holes at the bottom of the beam by extending and retracting the telescopic rod 3.

[0033] Reference Figure 1 and Figure 2 The bottom plate 1 is provided with a limit member 7 on both sides of the telescopic rod 3. The limit member 7 includes a fixed plate 71 and a movable plate 72. In this embodiment, the fixed plate 71 and the movable plate 72 are both U-shaped plates. The outer wall size of the movable plate 72 matches the inner wall size of the fixed plate 71. The fixed plate 71 is vertically installed on the bottom plate 1, and the movable plate 72 is vertically slidably installed in the fixed plate 71.

[0034] Reference Figure 1 A number of fixing holes 9 are vertically spaced apart on the side walls of the fixed plate 71 and the movable plate 72. The intervals between the fixing holes 9 on the fixed plate 71 and the movable plate 72 are the same. Bolts are installed in the fixing holes 9 to fix the movable plate 72 to the fixed plate 71 through the bolts. The position of the movable plate 72 relative to the fixed plate 71 is adjusted by adjusting the bolts installed in different fixing holes 9, thereby adjusting the overall height of the limiter 7.

[0035] Reference Figure 1 The fixed plate 71 is provided with a slide groove 10 along the height direction, and the upper end of the slide groove 10 passes through the upper surface of the fixed plate 71, and the movable plate 72 is provided with a limiting groove 11 along the height direction. In this embodiment, the limiting groove 11 is a waist-shaped groove, the slide groove 10 and the limiting groove 11 have the same width, and the limiting groove 11 is opened relative to the slide groove 10.

[0036] Reference Figure 1A limit rod 6 is horizontally installed at the upper end of the telescopic rod 3. Both ends of the limit rod 6 in the length direction are slidably penetrated into the slide groove 10 opened in the fixed plate 71 and the limit groove 11 opened in the movable plate 72. The limit rod 6 slides through the slide groove 10 and the limit groove 11 to limit the telescopic height of the telescopic rod 3.

[0037] Reference Figure 1 In order to facilitate the staff to adjust the height of the electric drill 5, a signal transmitter 12 is installed at one end of the limit rod 6 in the length direction, and a signal receiver is installed on the base plate 1. The signal receiver is used to receive the data of the signal transmitter 12, that is, the distance between the limit rod 6 and the base plate 1.

[0038] Reference Figure 1 In order to facilitate the staff to read the data of the signal receiver, the signal receiver is connected to a display screen 13. The display screen 13 is installed on the base plate 1, and the signal receiver is installed in the display screen 13. The display screen 13 processes the data of the signal receiver and converts it into digital data for display on the display screen 13.

[0039] Reference Figure 1 and Figure 2 In this embodiment, the end cover of the electric drill 5 is provided with a dust collecting cover 8, which is used to collect dust generated by the electric drill 5 when drilling the rebar holes. The dust collecting cover 8 is made of transparent material, and the integrated cover has a structure that is larger at the top and smaller at the bottom, that is, a trumpet shape. The lower end of the dust collecting cover 8 is connected to the electric drill 5.

[0040] Reference Figure 1 In order to ensure the height accuracy of the electric drill 5, in this embodiment, scale lines 14 are provided outside the movable plate 72 and the limit plate.

[0041] Reference Figure 1 , the drill bit at the end of the electric drill 5 extends out of the upper end of the dust collecting cover 8.

[0042] Reference Figure 1 and Figure 2 The lower end of the dust hood 8 is connected to and communicated with a spring telescopic tube 15. The end of the spring telescopic tube 15 away from the dust hood 8 is connected to a dust collector 16. The dust collected by the dust hood 8 is collected by the dust collector 16. The setting of the spring telescopic tube 15 enables the spring telescopic tube 15 to be stretched according to the depth of the drilling hole, and to shrink along with the shrinkage of the telescopic rod 3 when the telescopic rod 3 shrinks.

[0043] Reference Figure 1 In order to facilitate the staff to move the auxiliary device, a number of rollers 2 are installed on the side of the base plate 1 away from the telescopic rod 3. In this embodiment, the rollers 2 are universal brake wheels; and in order to facilitate the staff to push the auxiliary device, a handle 21 is fixedly installed on the surface of the base plate 1.

[0044] Reference Figure 1In order to improve the stability of the auxiliary device, a plurality of support rods 17 are threadedly installed on the base plate 1. In this embodiment, four support rods 17 are installed and are respectively installed near the four corners of the base plate 1.

[0045] Reference Figure 1 In this embodiment, in order to facilitate the rotation of the support rod 17 so that the support rod 17 moves closer to or away from the ground, a handle 21 is installed at the end of the base plate 1; in order to improve the stability of the support rod 17 after it contacts the ground, a rubber pad 20 is fixed at the bottom of the support rod 17.

[0046] Reference Figure 1 Since the position where the auxiliary device stays is not always horizontal, in this embodiment, a level bubble 18 is horizontally installed on the base plate 1. The staff can quickly judge whether the base plate 1 is in a horizontal state through the level bubble 18; when the base plate 1 is tilted, the support rod 17 is adjusted to move it away from or close to the ground so that the base plate 1 is in a horizontal state.

[0047] The implementation principle of this embodiment is: before using the electric drill 5 to drill the rebar planting hole, confirm the distance between the bottom of the beam and the ground, and use this height to adjust the telescopic height of the telescopic rod 3.

[0048] When the ground is horizontal, the auxiliary device is pushed to the drilling position by the handle 21 , and then the roller 2 is fixed, and the telescopic rod 3 is adjusted to move toward the ground until the rubber pad 20 contacts the ground.

[0049] Start the telescopic rod 3 to reach the preset height, fix the movable plate 72 and the fixed plate 71 according to the height of the limiting rod 6 installed at the upper end of the telescopic rod 3, at this time, the surface of the limiting rod 6 abuts against the upper side wall of the limiting groove 11, then adjust the telescopic rod 3 to the initial position, and install the electric drill 5 on the mounting seat 4, and complete the installation of the dust hood 8, the spring telescopic tube 15 and the vacuum cleaner 16 at the same time.

[0050] After the installation is completed, start the electric drill 5 and the telescopic rod 3. Driven by the telescopic rod 3, the electric drill 5 begins to drill the rebar hole. When the limit rod 6 abuts against the upper side of the limit groove 11, the rebar hole drilled by the electric drill 5 reaches the preset height. Then, under the action of the telescopic rod 3, the electric drill 5 returns to the initial position. The staff can rotate the support rod 17 to release the fixation of the auxiliary device and push it to the next drilling position through the handle 21 to open the rebar hole.

[0051] When the ground is not horizontal, move the auxiliary device to the drilling position through the handle 21, fix the roller 2, rotate the support rod 17 so that the rubber pad 20 contacts the ground, observe the level bubble 18 installed on the base plate 1, and judge whether the base plate 1 is in a horizontal state; drive the support rod 17 to move away from or closer to the ground by rotating the corresponding hand wheel 19 until the base plate 1 is in a horizontal state.

[0052] Then adjust the telescopic rod 3 and fix the movable plate 72 to the fixed plate 71, install the electric drill 5, dust cover 8, spring telescopic tube 15 and vacuum cleaner 16, and drill the anchor hole after the installation is completed.

[0053] After the depth of the rebar hole reaches the requirement, extend the telescopic rod 3 to the initial position, rotate the support rod 17 to release the support of the auxiliary device, push the roller 2 through the handle 21 to move the auxiliary device to the next punching position, and then repeat the above operation until all punching operations are completed.
