Description

Technical Field

[0001] The invention relates to an electric drill hole-punching auxiliary tool and a use method thereof. Background Art

[0002] At the construction site of a hydropower station, it is sometimes necessary to drill holes vertically upwards with an electric drill (impact drill). When the drilling position is high, workers need to use tools such as stepladders to work at height, which poses a safety hazard of workers falling. The continuous vibration of the electric drill gives workers a reaction force, making them unstable, which increases the safety hazard of workers falling. When drilling holes, workers are too close to the drilling position, and the dust generated by the drilling can easily cause workers to be blinded, which is also a safety hazard. In addition, workers hold the electric drill in an awkward posture to drill holes, and the continuous vibration when drilling makes them extremely prone to fatigue. Summary of the invention

[0003] The purpose of the present invention is to provide an electric drill drilling auxiliary tool and a method of using the electric drill. The present invention has the advantages of reducing the potential safety hazards of workers when drilling holes at high places and reducing the fatigue level of workers.

[0004] The technical solution of the present invention is as follows: an electric drill drilling auxiliary tool comprises a bracket, a vertical sleeve is provided on one side of the bracket, the sleeve is fixed to the upper part of the bracket, a lifting rod is provided in the sleeve, the upper end of the lifting rod extends out of the sleeve, a plurality of horizontal pin holes are provided on the lifting rod, and the plurality of pin holes are vertically distributed, a pin column is provided in one of the pin holes, one end of the pin column extends out of the sleeve, a through hole matching with the pin column is provided on the sleeve, the through hole is in the shape of a vertical long strip, a rolling body is provided at the outer end of the pin column, a tilting rod is provided on the lower side of the rolling body, one end of the tilting rod extends toward the bracket and exceeds the bracket, and the tilting rod is hinged to the bracket.

[0005] In the aforementioned electric drill drilling auxiliary tool, a bottom plate is provided at the lower end of the bracket, and the bottom plate extends toward one side of the lifting rod.

[0006] In the aforementioned electric drill drilling auxiliary tool, a rubber sleeve is provided at the end of the tilting rod extending toward the bracket.

[0007] In the aforementioned electric drill drilling auxiliary tool, the rolling element is a bearing.

[0008] In the aforementioned electric drill drilling auxiliary tool, a long groove cooperating with the rolling body is provided on the side of the tilting rod close to the sleeve.

[0009] In the aforementioned electric drill drilling auxiliary tool, a gear adjustment mechanism is provided on the casing, and the gear adjustment mechanism includes a bending plate located on the outside of the casing, the bending part of the bending plate is hinged to the casing, and the upper end of the bending plate is provided with a locking pin that passes through the casing and is inserted into one of the pin holes, and the lower end of the bending plate is provided with a spring connected to the casing.

[0010] In the aforementioned electric drill drilling auxiliary tool, a guide cut angle is provided at the end of the locking pin, and the cut surface of the guide cut angle faces downward.

[0011] The method of using the aforementioned electric drill drilling auxiliary tool is to fix the electric drill on the upper end of the lifting rod, turn on the power of the electric drill, and press down the lifting rod to make the electric drill rise to drill a hole.

[0012] Compared with the prior art, the present invention enables workers to operate the electric drill on the ground to perform drilling operations without the need for high-altitude operations, thereby eliminating the potential safety hazard of workers falling and getting injured. Since the workers are located on the ground to operate when drilling, the distance between the workers and the drilling position is large, and the dust from drilling is not easy to enter the workers' eyes, and the workers are not easy to squint, which further reduces the potential safety hazard. When drilling holes, the workers press down the end of the tilting rod in a standing position to make the electric drill rise to drill holes. Compared with the posture of raising the electric drill with both hands to drill holes, it is less prone to fatigue, and the vibration force of the electric drill when drilling holes is weakened by the lifting rod and the tilting rod, and is not easily transmitted to the workers' arms. The workers are subjected to a small reaction force, which makes them less prone to fatigue. Therefore, the present invention has the advantages of reducing the potential safety hazards of workers when drilling holes at heights and reducing the degree of fatigue of workers.

The hinge point between the tilting rod 8 and the bracket 1 is marked as point A, and the distance between point A and the lifting rod 3 is smaller than the distance between point A and the rubber sleeve 10.

[0018] A bottom plate 9 is provided at the lower end of the bracket 1 , and the bottom plate 9 extends toward one side of the lifting rod 3 .

[0019] The side of the tilting rod 8 close to the sleeve 2 is provided with a long groove 11 that matches the rolling body 7. The long groove 11 is used to limit the axial position of the rolling body 7, and the depth of the long groove 11 is less than the outer ring thickness of the rolling body 7.

[0020] The sleeve 2 is provided with a gear adjustment mechanism, which is located above the through hole 6. The gear adjustment mechanism includes a V-shaped bending plate 12 located on the outside of the sleeve 2. The bending part of the bending plate 12 is hinged to the sleeve 2. The upper end of the bending plate 12 is provided with a locking pin 13 that passes through the sleeve 2 and is inserted into one of the pin holes 4.
