Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a drilling device for water conservancy construction. Background Art

[0002] Water conservancy construction is the development of water resources and the prevention of floods. At present, a handheld spiral drill is used for drilling in the process of water conservancy construction. During the drilling process, the spiral blade of the handheld spiral drill is spirally fed into the soil to drill the soil. After the drilling is completed, the spiral blade is pulled out and the spiral blade continues to rotate to separate the soil debris from the surface of the spiral blade. As a result, the soil debris splashes everywhere, which can easily cause the operator to be injured by the splashing soil debris. In response to the above problem, for example, a water conservancy construction drilling device disclosed in the patent with publication number CN217129442U has a retaining cloth located on the side of the spiral blade, and an avoidance gap is left between the retaining cloth and the spiral blade. In this way, when the spiral blade of the handheld spiral drill is pulled out of the soil, the retaining cloth can block the splashing soil debris to reduce the risk of the splashing soil debris injuring the operator. However, the retaining cloth in the drilling device has low structural strength and is easy to bend and deform. When the operator approaches the retaining cloth, the flying debris blocked by it will still collide with the operator, resulting in limited protection effect. Utility Model Content

[0024] Among them, through the provision of the protective tube 100, it is possible to block the flying soil debris when the spiral blades are pulled off the ground, thereby reducing the risk of the flying soil debris injuring the operator. Compared with the existing retaining cloth, the protective tube 100 in this embodiment has a high structural strength, a good effect in blocking the flying soil debris, and will not be caught on the threaded blades, so it is safer to use.

[0025] In this embodiment, a fixing component for limiting the hand-held rod 110 at the upper end of the slot 101 is provided on the outer wall of the protective tube 100. The fixing component includes an arc ring 120 relatively arranged on the outer wall of the protective tube 100. A retractable arc rod 130 is provided in the arc ring 120. One end of the arc rod 130 extends through the slot 101 to the corresponding arc ring 120 for limiting the hand-held rod 110.

[0026] In this embodiment, the arc ring 120 is relatively arranged on the outer wall of the protective tube 100 between the two sides of the notch 101. Through the arrangement of the arc ring 120 and the arc rod 130, in actual use, one end of the arc rod 130 extends out of the arc ring 120, passes through the corresponding notch 101 and is inserted into the other arc ring 120, thereby being able to support the hand-held rod 110 extending out of the notch 101, thereby limiting the hand-held rod 110 at the upper end of the notch 101, that is, achieving the fixation of the drill body in the protective tube 100, preventing the drill body from slipping out of the cavity opening, affecting the transportation of the drilling device;

[0027] In actual use, in order to better realize the vertical fixing of the protective tube 100 on the ground and facilitate its transportation, a handrail 121 is provided on the outer side of the arc ring 120 for the operator to hold.

[0028] Combination Figure 5 As shown, in this embodiment, an arc cavity 501 for slidingly installing a corresponding arc rod 130 is provided along its circumference in the arc ring 120, a strip groove 211 connecting the arc cavity 501 is provided on the upper side surface of one of the two arc rings 120 along its circumference, a lever 510 extending out of the strip groove 211 is provided on the arc rod 130, a positioning member for positioning the lever 510 is provided on the lever 510, and a retraction member for driving the corresponding arc rod 130 to retract is provided in the other of the two arc rings 120, and the lever 510 is pushed along the strip groove 211 to drive the arc rod 130 in the other arc ring 120 to extend.

[0030] The lever 510 penetrates the strip groove 211 and is threadedly connected to the corresponding arc rod 130, so that the arc rod 130 and the lever 510 are installed in the corresponding arc ring 120, so that the lever 510 can be moved along the strip groove 211 to drive the arc rod 130 to extend or retract into the arc cavity 501;

[0031] The retracting member is provided so that the arc rod 130 is driven to retract into the corresponding arc cavity 501 in a natural state. At this time, when the lever 510 is toggled to drive the arc rod 130 to extend and insert it into another arc cavity 501, the arc rod 130 in the other arc cavity 501 is pushed out, so that the arc rod 130 can be inserted into the previous arc cavity 501, thereby realizing that the arc rod 130 better supports the hand-held rod 110; when the lever 510 is toggled to drive the arc rod 130 to retract into the arc cavity 501, the other arc rod 130 retracts into the corresponding arc cavity 501 under the action of the retracting member, thereby releasing the support for the hand-held rod 110, so that the drilling device can perform drilling operations. Therefore, the present embodiment can synchronously drive the arc rods 130 on both sides to extend and retract synchronously by toggling the lever 510, which is convenient for operation and convenient for use.

[0032] Among them, by setting the positioning member, the positioning member can fix the lever 510, that is, it can achieve the extension or retraction of the corresponding arc rod 130, and adjust the extension and retraction of the arc rod 130.

Thus, the first spring 420 is installed so that it always drives the first retaining ring 402 to move into the spring installation cavity 401, thereby driving the arc rod 130 to retract into the arc ring 120.

[0036] Combination Figure 5As shown, in this embodiment, positioning holes 212 are relatively provided on the upper side surface of the other arc ring 120 and at the two ends of the strip groove 211; the positioning member includes a fixing sleeve 520 sleeved on the outside of the protruding end of the lever 510, and the protruding end of the lever 510 is provided with a driving member for driving the fixing sleeve 520 to move toward the arc ring 120, and the fixing sleeve 520 is provided with a positioning column 521 that can be extended into the corresponding positioning hole 212.

[0037] In this embodiment, the driving member drives the fixing sleeve 520 to move toward the arc ring 120 along the lever 510, driving the positioning column 521 thereon to be inserted into the corresponding positioning hole 212, thereby fixing the lever 510, that is, fixing the arc rod 130, to prevent the arc rod 130 from retracting into the corresponding arc ring 120 under the resetting action of the arc rod 130 on the other side, thereby affecting the arc rod 130 extending out to support the handle bar 110;

[0038] When the lever 510 needs to be moved to adjust the telescopic movement of the arc rod 130, the lever 510 can be released by moving the fixing sleeve 520 along the upper body of the lever 510 to drive the positioning column 521 to disengage from the positioning hole 212. At this time, the lever 510 can be slid along the strip groove 211 to adjust the telescopic movement of the arc rod 130.

[0039] In this embodiment, a driving chamber 522 opening outward is provided in the fixed sleeve 520, and a plug 530 is threadedly connected to the opening of the driving chamber 522; the driving member includes a second baffle ring 540 arranged on the protruding end of the lever 510, and the lever 510 located in the driving chamber 522 is sleeved with a second spring 550 for driving the fixed sleeve 520 to move toward the arc ring 120.

[0040] In this embodiment, the opening of the driving cavity 522 is arranged toward the end of the fixing sleeve 520 away from the corresponding arc ring 120 side, and the protruding end of the lever 510 is provided with a threaded column for installing the second retaining ring 540, and the threaded column is threadedly connected with a nut for fixing the second retaining ring 540.

[0041] Working principle: one operator holds the handrail 121 to place the protective cylinder 100 on the ground to be drilled, and the other operator lifts the fixing sleeve 520 and drives the fixing sleeve 520 to move along the strip groove 211, so that the arc rod 130 retracts into the corresponding arc ring 120, and then holds the hand-held rod 110 to press down the drill body along the slot 101 to drill. After drilling to the specified depth, the drill body is lifted along the slot 101 to complete the drilling operation. In this process, the protective cylinder 100 is used to block the flying soil and debris, thereby reducing the risk of the flying soil and debris injuring the operator. When the drilling operation is completed, the fixing sleeve 520 is lifted and driven to move along the strip groove 211, so that the arc rod 130 is extended and inserted into the corresponding arc cavity 501, and then the arc rod 130 supports the hand-held rod 110, so that the drill body is fixed in the protective cylinder 100, so as to facilitate the transportation of the drilling device.

[0042] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
