Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary tool for drilling holes with an electric drill. Background Technology
[0002] At hydroelectric power station construction sites, it is sometimes necessary to drill vertically upwards using electric drills (impact drills). When drilling at high positions, workers need to use tools such as A-frame ladders to work at height, posing a safety hazard of falls. The continuous vibration of the electric drill exerts a reaction force on the worker, making it difficult to stand, further increasing the risk of falls. When drilling, if the worker is too close to the drilling site, the dust generated can easily get into their eyes, which is also a safety hazard. Furthermore, the awkward posture with which workers hold the electric drill, combined with the continuous vibration, makes them extremely prone to fatigue. Utility Model Content
[0003] The purpose of this invention is to provide an auxiliary tool for electric drills. This invention has the advantages of reducing safety hazards and worker fatigue when drilling at heights.
[0004] The technical solution of this utility model is as follows: A drilling auxiliary tool for electric drills includes a bracket, a vertical sleeve on one side of the bracket, the sleeve being fixed to the upper part of the bracket, a lifting rod inside the sleeve, the upper end of the lifting rod extending out of the sleeve, multiple horizontal pin holes on the lifting rod, the multiple pin holes being vertically distributed, a pin in one of the pin holes, one end of the pin extending out of the sleeve, a through hole on the sleeve that mates with the pin, the through hole being a vertical elongated strip, a rolling element on the outer end of the pin, a rocker arm on the lower side of the rolling element, one end of the rocker arm extending toward the bracket and beyond the bracket, the rocker arm being hinged to the bracket.
[0005] In the aforementioned electric drill drilling auxiliary tool, the lower end of the bracket is provided with a base plate, which extends towards the lifting rod.
[0006] In the aforementioned electric drill drilling auxiliary tool, the end of the rocker arm extending toward the bracket is provided with a rubber sleeve.
[0007] In the aforementioned electric drill drilling auxiliary tool, the rolling element is a bearing.
[0008] In the aforementioned electric drill drilling auxiliary tool, the rocker arm has a long groove on the side near the sleeve that mates with the rolling element.
[0009] In the aforementioned electric drill drilling auxiliary tool, the sleeve is provided with a gear adjustment mechanism. The gear adjustment mechanism includes a bending plate located on the outside of the sleeve. The bending part of the bending plate is hinged to the sleeve. The upper end of the bending plate is provided with a locking pin that passes through the sleeve and is inserted into one of the pin holes. The lower end of the bending plate is provided with a spring that connects to the sleeve.
[0010] In the aforementioned electric drill drilling auxiliary tool, the end of the locking pin is provided with a guide chamfer, and the tangent of the guide chamfer faces downward.
[0011] Compared with existing technologies, this invention allows workers to operate electric drills for drilling from the ground, eliminating the need for working at heights and thus reducing the safety hazard of falls. Because the worker operates on the ground, the greater distance between the worker and the drilling location reduces the likelihood of drilling dust entering the worker's eyes, further lowering safety risks. During drilling, the worker stands and presses down on the end of the lever to raise the drill, which is less tiring than raising the drill with both hands. Furthermore, the vibration from the drill is weakened by the lifting rod and lever, minimizing the transmission to the worker's arms and reducing the reaction force, thus reducing fatigue. Therefore, this invention has the advantages of reducing safety risks when drilling at heights and reducing worker fatigue. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0016] Example. A drilling auxiliary tool, such as... Figure 1As shown, the system includes a support 1 with a height of 2.5m. A vertical sleeve 2 with a length of 1.2m is provided on one side of the support 1. The sleeve 2 is fixed to the upper part of the support 1. A lifting rod 3 with a length of 2.5m is provided inside the sleeve 2. The upper end of the lifting rod 3 extends out of the sleeve 2. The lifting rod 3 has multiple horizontal pin holes 4, which are vertically distributed. A pin 5 is provided in one of the pin holes 4. One end of the pin 5 extends out of the sleeve 2. The sleeve 2 has a through hole 6 that mates with the pin 5. The through hole 6 is a vertical elongated strip. The length of the through hole 6 is two to four times the distance between adjacent pin holes 4. A rolling element 7, which is a bearing, is provided on the outer end of the pin 5. The pin 5 is fixed to the inner ring of the bearing. A rocker arm 8 is provided on the lower side of the rolling element 7. One end of the rocker arm 8 extends toward the support 1 and beyond the support 1. A rubber sleeve 10 is provided at the end of the rocker arm 8 that extends toward the support 1. The rocker arm 8 is hinged to the support 1. The hinge point between the rocker arm 8 and the bracket 1 is denoted as point A. The distance between point A and the lifting rod 3 is less than the distance between point A and the rubber sleeve 10.
[0017] The lower end of the bracket 1 is provided with a base plate 9, which extends toward the lifting rod 3.
[0018] The rocker arm 8 has an elongated groove 11 on the side near the sleeve 2 that mates with the rolling element 7. The elongated groove 11 is used to limit the axial position of the rolling element 7, and the depth of the elongated groove 11 is less than the outer ring thickness of the rolling element 7.
[0019] 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. The lower end of the bending plate 12 is provided with a spring 14 that connects to the sleeve 2.
[0020] The end of the locking pin 13 is provided with a guide chamfer 15, and the chamfer of the guide chamfer 15 faces downward.
[0021] Instructions for use: Fix the electric drill to the upper end of the lifting rod 3. A corresponding adapter bracket can be installed between the lifting rod 3 and the electric drill. For example... Figure 1As shown, based on the height of the drilling position, the height of the lifting rod 3 is coarsely adjusted using the gear adjustment mechanism to bring the lifting rod 3 close to the drilling position. Specifically, first, the rubber sleeve 10 is lifted, causing the rocker arm 8 to rotate counterclockwise, separating the left end of the rocker arm 8 from the rolling element 7, and axially pulling out the combination of the rolling element 7 and the pin 5; then, the lower part of the bending plate 12 is pressed down to separate the locking pin 13 from the lifting rod 3, allowing the height of the lifting rod 3 to be adjusted. The bending plate 12 is then released, and under the action of the spring 14, it is removed. The bending plate 12 rotates, causing the locking pin 13 to re-insert into the pin hole 4, preventing the lifting rod 3 from falling down. Finally, the combination of the rolling element 7 and the pin 5 is reinstalled. In this step, the lifting range of the lifting rod 3 is large, reaching over 1.5m, making this invention suitable for a wide range of drilling heights.
[0022] Turn on the power of the electric drill, and by pressing down the rubber sleeve 10, the rocker arm 8 rotates. The rocker arm 8 raises the height of the rolling body 7. The rolling body 7 raises the height of the lifting rod 3 through the pin 5, so that the electric drill contacts the drilling position and can drill smoothly.
[0023] In this embodiment, because the lifting rod 3 moves vertically, the electric drill will not deviate horizontally during drilling. There is no horizontal resistance on the drill bit, making it less prone to breakage. This makes it suitable for drilling on surfaces of various strengths, with a wide range of applications. Furthermore, the drilled holes are standard round holes with high precision, meeting various needs on construction sites. Simultaneously, the large lifting range of the electric drill further enhances the applicability of this invention. In addition, this invention has a simple structure and relatively low cost.
