Description

Technical Field

[0001] This utility model relates to the field of hole-opening technology, and in particular to a hole-opening device for roof slab wall tie bars. Background Technology

[0002] During the construction of a building, when the internal secondary structure is being built, holes need to be made at the top of the infill wall first. Then, wall tie bars are inserted into the holes before the wall is built. The wall tie bars improve the wall's resistance to collapse. During the hole-making process, a hole-making device is required. The hole-making device mainly consists of a lifting frame and a drilling machine (impact drill). The drilling machine is fixed to the top of the lifting frame by a mounting plate. The lifting frame can drive the drilling machine to rise and fall via an electric push rod. The drill bit of the drilling machine is fitted with a guard to prevent dust from falling. When in use, the drilling machine is moved to the hole-making location by the lifting frame, and then the electric push rod is started. The electric push rod drives the drilling machine to make the hole.

[0003] During the drilling process, dust falls into the baffle. However, since the baffle is directly fitted onto the surface of the drill bit, friction occurs between the drill bit and the baffle during rotation, resulting in severe wear at the through-hole of the baffle. Dust can then fall from the worn area into the drill joint, requiring the baffle to be replaced. However, since other parts of the baffle are still usable, discarding the baffle directly would be wasteful. There is a need for further optimization in reducing wear on the baffle. Therefore, this application provides a top slab wall tie bar drilling device to meet this need. Utility Model Content

[0004] This utility model provides a top plate wall tie bar opening device to address the need for further optimization in reducing wear of the baffle.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A device for drilling holes for wall tie rods in a roof slab includes a lifting frame, a mounting plate fixed to the top of the lifting frame, a drilling machine fixed to the mounting plate, a guard sleeved on the drill bit of the drilling machine, and further includes: The rotating mechanism includes an outer ring embedded in the bottom of the baffle, a groove is provided on the inner wall of the outer ring, a slider is slidably connected to the inner wall of the groove, an inner ring is fixed to the inner wall of the slider, the side of the inner ring is slidably connected to the inner wall of the outer ring, a rubber sleeve is fixed to the inner wall of the inner ring, the rubber sleeve is fitted on the surface of the drill bit of the drilling machine, and a limit component is provided at the bottom of the baffle.

[0006] Preferably, the limiting component includes a mounting sleeve fixed to the side of the mounting plate, a support rod slidably connected to the inner wall of the mounting sleeve, a bolt threadedly connected to the side of the mounting sleeve, the bolt abutting against the surface of the support rod, and the top of the support rod fixed to the bottom of the cover.

[0007] Preferably, the bottom of the support rod is arc-shaped.

[0008] Preferably, a sealing ring is embedded in the inner wall of the outer ring, and the sealing ring is attached to the side of the inner ring.

[0009] Preferably, a retaining ring is fixed to the top of the outer ring, and a groove is formed at the bottom of the retaining ring, with the groove located above the inner ring.

[0010] Preferably, the top of the retaining ring is provided with a continuous inclined surface one and an inclined surface two. The inclined surface one is away from the inner ring. The top of the inner ring is fixed with a retaining ring two. The end of the retaining ring two is fixed with a retaining ring one. The retaining ring one is attached to the surface of the inclined surface one, and the retaining ring two is attached to the surface of the inclined surface two.

[0011] Preferably, the surface of the second inclined plane is provided with a storage groove.

[0012] Preferably, the bottom of the rubber sleeve has an arc-shaped guide surface.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting an outer ring, an inner ring, a slide groove, a slider, and a limiting component, after the guard is fitted onto the drill bit, the guard is installed through the limiting component to prevent the guard from shaking or rotating with the drill bit during use, thus protecting the guard. During use, the drill bit drives the inner ring to rotate through the rubber sleeve, and the inner ring drives the slider to rotate on the inner wall of the slide groove, thereby preventing the drill bit from wearing down the through hole of the guard and improving the durability of the guard.

[0014] By setting a sealing ring and a retaining ring, the sealing ring prevents dust from entering between the slider and the slide groove, thereby avoiding significant wear between the slider and the slide groove and further improving durability. By setting a retaining ring and a groove, the retaining ring can further block dust, preventing dust from entering between the outer ring and the inner ring, improving durability. Secondly, the groove prevents the retaining ring from directly wearing down the inner ring, improving the durability of the inner ring. Furthermore, the first retaining ring is attached to the surface of the first inclined surface, which is tilted upwards. Due to the gravity of the dust itself, it is difficult for dust to enter the second retaining ring. Even if a small amount of dust enters the second retaining ring, it can be blocked by the second retaining ring and the second inclined surface. If the dust at the second retaining ring still flows downwards, the dust will flow into the collection groove and be collected, thereby again preventing dust from entering between the inner ring and the outer ring and improving the durability of the inner and outer rings.

Detailed Implementation

[0017] The following is a detailed description of a top slab wall tie rod opening device provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0018] like Figures 1-4 As shown, an embodiment of this utility model provides a device for drilling holes in a top slab wall tie rod, including a lifting frame 1, a mounting plate 2 fixed to the top of the lifting frame 1, a drilling machine 3 fixed on the mounting plate 2, a baffle 4 sleeved on the drill bit of the drilling machine 3, and further including: The rotating mechanism 5 includes an outer ring 6 embedded in the bottom of the baffle 4. A groove 8 is formed on the inner wall of the outer ring 6, and a slider 9 is slidably connected to the inner wall of the groove 8. An inner ring 7 is fixed to the inner wall of the slider 9, and the side of the inner ring 7 is slidably connected to the inner wall of the outer ring 6. A rubber sleeve is fixed to the inner wall of the inner ring 7 and is fitted onto the surface of the drill bit of the drilling machine 3. A limit component is provided at the bottom of the baffle 4. The lifting frame 1 adjusts the height of the mounting plate 2 to adapt to the opening requirements of top plates of different heights. The mounting plate 2 provides an installation base for the drilling machine 3, ensuring that the drilling machine 3 is fixed in position. The system provides drilling power to open holes in the top plate. The baffle 4 blocks the spread of dust generated during drilling, reducing dust pollution. The outer ring 6 is fixed to the bottom of the baffle 4, providing a carrier for the slide 8. The slide 8 cooperates with the slider 9 to guide the inner ring 7 to rotate around the outer ring 6. The slider 9 realizes the rotational connection between the inner ring 7 and the outer ring 6. The inner ring 7 is linked to the drill bit through a rubber sleeve. The rubber sleeve enhances the friction between the inner ring 7 and the drill bit, causing the inner ring 7 to rotate synchronously with the drill bit. The limiting component fixes the position of the baffle 4 to prevent the baffle 4 from shaking or rotating with the drill bit, protecting the baffle 4 and extending its service life.

[0019] like Figure 2As shown in this embodiment, the limiting component includes a mounting sleeve 19 fixed to the side of the mounting plate 2. A support rod 18 is slidably connected to the inner wall of the mounting sleeve 19. A bolt is threadedly connected to the side of the mounting sleeve 19. The bolt abuts against the surface of the support rod 18. The top of the support rod 18 is fixed to the bottom of the cover 4. The mounting sleeve 19 provides sliding space for the support rod 18. The support rod 18 connects the mounting sleeve 19 and the cover 4, and plays a supporting and limiting role for the cover 4.

[0020] like Figure 2 As shown in this embodiment, the bottom of the support rod 18 is arc-shaped. The arc-shaped structure at the bottom of the support rod 18 makes the sliding of the support rod 18 with the inner wall of the mounting sleeve 19 smoother.

[0021] like Figure 3 As shown in this embodiment, a sealing ring 10 is embedded in the inner wall of the outer ring 6. The sealing ring 10 is attached to the side of the inner ring 7, sealing the gap between the outer ring 6 and the inner ring 7. This prevents dust generated during drilling from entering between the slide groove 8 and the slider 9, avoiding dust from causing wear or jamming between the slider 9 and the slide groove 8, ensuring the smooth rotation of the inner ring 7 and the outer ring 6, and improving the service life of the rotating mechanism 5.

[0022] like Figure 3 As shown in this embodiment, a retaining ring 11 is fixed to the top of the outer ring 6, and a groove 12 is provided at the bottom of the retaining ring 11. The groove 12 is located above the inner ring 7. The retaining ring 11 prevents dust falling from the top from entering between the outer ring 6 and the inner ring 7, further enhancing the dustproof effect. The groove 12 creates a small gap between the bottom of the retaining ring 11 and the top of the inner ring 7, preventing the retaining ring 11 from directly contacting the rotating inner ring 7 and causing wear, thus protecting the inner ring 7 and the retaining ring 11 and improving the service life of the components.

[0023] like Figure 3 As shown in this embodiment, the top of the retaining ring 11 is provided with a continuous inclined surface 13 and an inclined surface 14. The inclined surface 13 is away from the inner ring 7. The top of the inner ring 7 is fixed with a shielding ring 17. The end of the shielding ring 17 is fixed with a shielding ring 16. The shielding ring 16 is attached to the surface of the inclined surface 13, and the shielding ring 17 is attached to the surface of the inclined surface 14. The inclined surfaces 13 and 14 are inclined upward to prevent dust from sliding along the inclined surfaces. The shielding ring 16 is attached to the inclined surface 13, and the shielding ring 17 is attached to the inclined surface 14, forming a multi-layer dustproof barrier to prevent dust from entering between the outer ring 6 and the inner ring 7.

[0024] like Figure 3 As shown in this embodiment, a collection groove 15 is provided on the surface of the second inclined surface 14. The collection groove 15 collects the dust that slides down the second inclined surface 14, preventing the dust from continuing to flow downward and entering between the outer ring 6 and the inner ring 7, further improving the dustproof effect, reducing the impact of dust on the rotating mechanism 5, and reducing component wear.

[0025] like Figure 3 As shown in this embodiment, the bottom of the rubber sleeve is provided with an arc-shaped guide surface, which guides the drill bit to be smoothly inserted into the rubber sleeve, facilitating the assembly of the rubber sleeve and the drill bit.

[0026] Working principle: The cover 4 is placed on the drill bit of the drilling machine 3, so that the rubber sleeve on the inner wall of the inner ring 7 fits the surface of the drill bit. The bolts on the side of the mounting sleeve 19 are tightened to press against the support rod 18 and fix the position of the cover 4. Operate the lifting frame 1 to align the drill bit of the drilling machine 3 with the position to be opened on the top plate. The first 16 of the retaining ring 11 is attached to the first 13 of the inclined surface, the second 17 of the retaining ring is attached to the second 14 of the inclined surface, and the sealing ring 10 is attached to the side of the inner ring 7. Start the drilling machine 3. The drill bit rotates and drives the inner ring 7 to rotate through the rubber sleeve. The inner ring 7 drives the slider 9 to slide in the slide groove 8. The dust generated by drilling is blocked by the baffle 4. After multiple uses, some dust will slide upward along the inclined surface 13. A small amount of dust that enters is blocked by the second baffle ring 17 and the second inclined surface 14, and finally falls into the collection groove 15. After drilling is completed, turn off the drilling machine 3, operate the lifting frame 1 to move the device away from the top plate, clean the dust inside the baffle 4, and prepare for the next drilling.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
