Description

Technical Field

[0001] This utility model belongs to the technical field of drilling positioning auxiliary devices, and more specifically, it relates to a small drilling positioning auxiliary device for building construction operations in confined spaces. Background Technology

[0002] In the construction industry, confined space operations are common. In such spaces, workers often need to use one hand to hold onto pipes or walls for balance while operating the drill with the other. The reaction force generated when the drill starts can easily cause the arm to lose control, which can not only exacerbate drilling positioning errors but also cause the drill to accidentally hit the surrounding building structure. At the same time, hand fatigue caused by prolonged single-handed operation can also cause the tool to fall, posing a dual safety hazard of equipment damage and personnel injury. To facilitate operations in confined spaces, a drilling positioning auxiliary device is needed.

[0003] Based on existing technology, it has been found that existing drilling positioning auxiliary devices are not easy to maintain stability in confined spaces, making it difficult to effectively support the drilling components and hindering effective drilling in confined spaces. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, this utility model relates to a small drilling positioning auxiliary device for construction work in confined spaces, so as to solve the problem that existing drilling positioning auxiliary devices are not easy to maintain stability in confined spaces, making it difficult to effectively support the drilling components.

[0005] This utility model provides a small drilling positioning auxiliary device for construction work in confined spaces, achieved through the following specific technical means: A small drilling positioning auxiliary device for construction work in confined spaces includes: an internal frame; two sets of opposing adjustment grooves on the outer wall of the internal frame; four sets of contraction grooves inside the internal frame; torsion blocks rotatably connected to each of the two sets of adjustment grooves; adjustment screws fixedly connected to the two ends of each of the two sets of torsion blocks; extension rods slidably connected to the interior of each of the four sets of contraction grooves; a tightening outer plate fixedly connected to the exterior of each of the two sets of extension rods on the same side; an inward-turning ring inside the circular through hole of the internal frame; four sets of circumferentially distributed top screws fixedly connected to the top of the inward-turning ring; an inner support ring at the top of the inward-turning ring; four sets of circumferentially distributed support frames fixedly connected to the bottom of the inner support ring; and docking sleeves rotatably connected to each of the four sets of support frames through shaft holes.

[0006] Preferably, the built-in frame is configured as a cuboid structure, and a circular through hole is provided in the middle of the built-in frame. Two sets of opposing shaft holes are provided on the inner wall of the circular through hole of the built-in frame.

[0007] Preferably, the four sets of shrinkage grooves are each connected to a rectangular through hole, and the two sets of opposite shrinkage grooves are respectively connected to the corresponding adjustment grooves through circular through holes; the middle positions of the two sets of torsion blocks are respectively set as hexagonal prism structures.

[0008] Preferably, the four sets of adjusting screws are each configured as threaded rod structures; the four sets of extended rod frames are each provided with threaded grooves that cooperate with the corresponding adjusting screws.

[0009] Preferably, the two sets of tightening outer plates are respectively snapped onto the outside of the built-in frame; the outer wall of the inner flip ring is fixed with two sets of cylindrical protrusions for rotatable connection in the corresponding shaft holes of the built-in frame.

[0010] Preferably, the inner support ring and the inner flip ring are coaxial; and the four sets of support frames are respectively provided with shaft holes.

[0011] Preferably, each of the four sets of mating sleeves has a threaded groove for engaging with the corresponding top screw; the top of each of the four sets of mating sleeves has a hexagonal prism-shaped protrusion.

[0012] The small drilling positioning auxiliary device for construction work in confined spaces proposed in this utility model has the following beneficial effects: 1. The four sets of outward-extending rods move outward under the control of the adjusting screws. The two sets of outward-extending rods on the same side are externally fixed to the outer plate. When the outward-extending rods move outward, the outer plate moves closer to the outer wall of the building until it is tightly pressed. The design of the outer plate being stuck outside the internal frame further enhances the stability of the device. The adjusting screw is set as a threaded rod structure, and the outward-extending rods have threaded grooves that match it. This common and mature threaded connection method is not only easy to manufacture and maintain, but also provides a stable transmission effect in actual operation, making it convenient to use. 2. The inner ring is rotatably connected to the corresponding shaft hole of the inner frame through the cylindrical protrusion on the outer wall, allowing it to flip flexibly. The top of the inner ring is fixed with four sets of circumferentially distributed top screws, which are connected to the docking sleeve at the bottom of the inner support ring through the shaft hole, so that the inner ring and the inner support ring keep synchronized. The inner support ring is used to support the electric drill. Simply flipping the inner ring will drive the inner support ring and the electric drill to rotate together, achieving precise angle adjustment. This design has great advantages in confined spaces and can meet the drilling needs in different directions. Attached Figure Description

The device is fixed in a confined space by a retraction mechanism, facilitating support for the electric drill. Two sets of adjusting grooves 2 are each rotatably connected to a torsion block 4. The torsion block 4 drives the adjusting screw 5 to rotate during rotation, allowing for position adjustment of the extension rod 6 via threaded control. Adjusting screws 5 are fixed to both ends of the two sets of torsion blocks 4. The adjusting screws 5 are used for rotation adjustment driven by the torsion blocks 4, facilitating position adjustment of the extension rod 6 via threaded control. Extension rods 6 are slidably connected inside the four sets of retraction grooves 3. The extension rod 6 is used for external... The device is moved and, in conjunction with the outer clamping plate 7, clamps the building's outer wall to maintain stability in confined spaces. Two sets of outward-extending rods 6 on the same side are externally fixed with clamping plates 7. The clamping plates 7, driven by the outward-extending rods 6, clamp the building wall to ensure stability of the entire device in confined spaces, facilitating drilling. An inward-flipping ring 8 is provided inside the circular through-hole of the built-in frame 1. The inward-flipping ring 8 assists in adjusting the angle of the electric drill by flipping, facilitating work in confined spaces. Four sets of circumferentially distributed top-connecting screws 9 are fixed to the top of the inward-flipping ring 8. The top-connecting screws 9 assist in connecting with the connecting sleeve. 12. A docking process is performed to allow the support frame 11 to dock with the inner ring 8. The top of the inner ring 8 is provided with an inner support ring 10. The inner support ring 10 is used to support the electric drill, facilitating drilling operations in confined spaces. Four sets of support frames 11 are fixedly connected to the bottom of the inner support ring 10 in a circular arrangement. The support frames 11 are used to connect with the docking sleeve 12 and the top connecting screw 9 to help the inner ring 8 and the inner support ring 10 maintain synchronization. The four sets of support frames 11 are rotatably connected to the docking sleeve 12 through shaft holes. The docking sleeve 12 is used to connect with the top connecting screw 9 to facilitate the inner ring 8 and the inner support ring 10 maintaining synchronization.

[0022] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, the built-in frame 1 is configured as a cuboid structure, and a circular through hole is provided in the middle of the built-in frame 1. Two sets of opposing shaft holes are provided on the inner wall of the circular through hole of the built-in frame 1.

[0023] The four sets of shrinkage grooves 3 are each connected to a rectangular through hole, and the two sets of opposite shrinkage grooves 3 are respectively connected to the corresponding adjustment grooves 2 through circular through holes; the middle positions of the two sets of torsion blocks 4 are respectively set as hexagonal prism structures.

[0024] The four sets of adjusting screws 5 are each configured as threaded rods; the four sets of extended rod brackets 6 are each provided with threaded grooves that cooperate with the corresponding adjusting screws 5.

[0025] Two sets of outer clamping plates 7 are respectively clamped to the outside of the inner frame 1; two sets of cylindrical protrusions for rotatable connection in the corresponding shaft holes of the inner frame 1 are fixed on the outer wall of the inner flip ring 8.

[0026] The inner support ring 10 and the inner flip ring 8 are kept coaxial; the four sets of support frames 11 are respectively provided with shaft holes.

[0027] Each of the four sets of mating sleeves 12 has a threaded groove for engaging with the corresponding top screw 9; the top of each of the four sets of mating sleeves 12 has a hexagonal prism protrusion.

[0028] The specific usage and function of this embodiment are as follows: In this invention, the device is placed in the operating space. Using tools such as a wrench, the hexagonal prism-shaped part of the torsion block 4 is clamped. As the torsion block 4 rotates, the adjusting screw 5 fixed to it rotates synchronously. Due to the threaded engagement, the outward extension rod 6 begins to move outward within the contraction groove 3. The outer clamping plates 7 fixed to the outside of the two sets of outward extension rods 6 on the same side gradually approach the outer wall of the building as the outward extension rods 6 move outward. After the outer clamping plates 7 contact the outer wall of the building, the torsion block 4 is rotated slowly and continuously. The clamping force applied by the outer clamping plates 7 to the outer wall of the building gradually increases until the device is stable and stationary in the confined space. The electric drill is placed on the inner support ring 10, utilizing the support of the inner support ring 10. The structure securely fixes the electric drill, ensuring it won't shake or shift during subsequent operations. When the drill angle needs to be adjusted to accommodate drilling in different directions within a confined space, the inner ring 8 is slowly flipped. The flipping of the inner ring 8, through the top connecting screw 9, the connecting sleeve 12, and the support frame 11, drives the inner support ring 10 and the electric drill mounted on the inner support ring 10 to rotate together. During angle adjustment, the flipping angle of the inner ring 8 is precisely controlled according to the actual drilling direction and position requirements. After achieving the ideal drilling angle, the stability of each component connection and the stability of the electric drill can be checked again, facilitating drilling operations in confined spaces.
