Description

Technical Field

[0001] This application relates to the field of construction technology for pre-embedded sleeves through beams, and in particular to a fixing device for pre-embedded sleeves through beams. Background Technology

[0002] In the construction of pipe penetrations in beam structures, pre-embedded sleeves need to be installed during beam pouring. These sleeves are embedded within the beam body, with a portion extending outwards to accommodate the pipe through. The installation accuracy of the pipe depends on the installation accuracy of the pre-embedded sleeves; therefore, it is essential to ensure the installation accuracy of the pre-embedded sleeves.

[0003] During concrete pouring, the embedded sleeves in beams are easily affected by the impact and vibration forces of the concrete, leading to displacement, floating, or sinking. Maintaining the initial position of the embedded sleeves is difficult, and fixing devices are generally required for positioning. Traditional fixing devices are typically designed specifically for the shape of the embedded sleeves, making them highly specialized and not universally applicable to sleeves of different diameters or shapes.

[0004] Therefore, there is a need for a fixing device that can be used for pre-embedded sleeves through beams of different diameters and shapes. Utility Model Content

[0005] Therefore, it is necessary to provide a fixing device for pre-embedded sleeves through beams, and its specific technical solution is as follows.

[0006] A fixing device for pre-embedded sleeves through beams includes a linear moving module and two clamping assemblies arranged opposite each other; the clamping assemblies are connected to the linear moving module, and the linear moving module drives the two clamping assemblies to move closer or further apart;

[0007] The clamping assembly includes multiple levels of arc-shaped sliders and rubber clamping blocks; each level of arc-shaped slider is provided with an arc-shaped groove and / or an arc-shaped protrusion, so that the arc-shaped protrusion of the next level arc-shaped slider slides into the arc-shaped groove of the previous level arc-shaped slider, and the number of the next level arc-shaped sliders is greater than the number of the previous level arc-shaped sliders; the rubber clamping block is connected to the arc-shaped slider at the end and is used to abut against the pre-embedded sleeve through the beam.

[0008] Furthermore, the inner wall of the arc-shaped groove is provided with an arc-shaped protrusion, and the outer wall of the arc-shaped protrusion is provided with an arc-shaped sliding groove; the arc-shaped protrusion is inserted into the arc-shaped sliding groove and slides in cooperation with the arc-shaped sliding groove.

[0009] Furthermore, the number of the next level of curved sliders is N times the number of the previous level of curved sliders, where N≥2.

[0010] Furthermore, the multi-stage arc-shaped slider includes a first arc-shaped slider, a second arc-shaped slider, a third arc-shaped slider, and a fourth arc-shaped slider; the first arc-shaped slider is provided with a first arc-shaped groove;

[0011] The second arc-shaped slider is provided with a second arc-shaped groove and a second arc-shaped protrusion, and the second arc-shaped protrusion slides in conjunction with the first arc-shaped groove;

[0012] The third arc-shaped slider is provided with a third arc-shaped groove and a third arc-shaped protrusion, and the third arc-shaped protrusion slides in conjunction with the second arc-shaped groove;

[0013] The fourth arc-shaped slider is provided with a fourth arc-shaped protrusion, which slides in conjunction with the third arc-shaped groove.

[0014] Furthermore, the two clamping components are divided into a first clamping component and a second clamping component; the first clamping component is movably connected to the linear motion module, and is driven by the linear motion module to move towards or away from the second clamping component; the second clamping component is fixedly connected to the linear motion module and remains stationary.

[0015] Furthermore, the linear motion module includes a connecting seat, a sliding block, a moving rod, a drive motor, and a fixed seat; the moving rod is rotatably mounted between the connecting seat and the fixed seat; the sliding block is connected to the moving rod, and the drive motor is connected to the moving rod, so that the moving rod rotates and the sliding block moves.

[0016] Furthermore, the first clamping component is mounted on the sliding block and moves with the sliding block; the second clamping component is mounted on the fixed base and remains stationary.

[0017] Furthermore, the first clamping assembly is rotatably mounted on the sliding block via a rotating shaft; the axis of the rotating shaft is perpendicular to the moving rod and the pre-embedded sleeve through the beam, respectively.

[0018] Furthermore, the rubber clamping block is connected to the arc-shaped slider at the end via a rotating shaft; the axis of the rotating shaft is parallel to the pre-embedded sleeve through the beam.

[0019] Furthermore, it also includes a connecting frame on which two sets of linear motion modules are mounted; each set of linear motion modules is connected to two oppositely arranged clamping components.

[0020] Beneficial Effects: The fixing device for pre-embedded sleeves in beams provided by this utility model can drive two relatively arranged clamping components to approach each other through a linear movement module, thereby clamping the pre-embedded sleeve. When clamping the pre-embedded sleeve, the clamping components, under the cooperation of multi-stage arc-shaped sliders, can adapt to the contour of the pre-embedded sleeve and slide relative to each other, so that the rubber clamping block on the arc-shaped slider at the end forms a shape corresponding to the outer contour of the pre-embedded sleeve, thus fitting against the outer contour surface of the pre-embedded sleeve. This can accommodate the fixing of pre-embedded sleeves with different diameters and shapes. When the two relatively clamping components press the pre-embedded sleeve, they can maintain stable clamping of the pre-embedded sleeve under the action of large friction.

[0042] Example

[0043] This embodiment provides a fixing device for pre-embedded sleeves in beams, refer to... Figure 1 As shown, it includes a connecting frame 1, on which two sets of parallel linear moving modules 2 are mounted. The two sets of linear moving modules 2 are arranged along the axial direction of the pre-embedded sleeve through the beam, and each set of linear moving modules 2 is equipped with two opposing clamping components. The linear moving modules 2 drive the two clamping components to move closer or further away, thereby clamping and fixing or releasing the pre-embedded sleeve through the beam. It should be noted that the two sets of clamping components are divided into a first clamping component 3 and a second clamping component 4. In this embodiment, the first clamping component 3 moves with the linear moving module 2, while the second clamping component 4 remains fixed. The pre-embedded sleeve through the beam is clamped when the first clamping component 3 moves toward the second clamping component 4. In other embodiments, the two sets of clamping components can also be configured to move separately with the linear moving module 2.

[0044] Reference Figure 2As shown, the clamping assembly includes multi-stage arc-shaped sliders and rubber clamping blocks 35. Each stage of the arc-shaped slider is provided with an arc-shaped groove and / or an arc-shaped protrusion. That is, some arc-shaped sliders only have arc-shaped grooves, some arc-shaped sliders only have arc-shaped protrusions, and some arc-shaped sliders have both arc-shaped grooves and arc-shaped protrusions. This allows the arc-shaped protrusions of the next stage arc-shaped slider to slide and engage with the arc-shaped grooves of the previous stage arc-shaped slider, and the number of the next stage arc-shaped sliders is greater than the number of the previous stage arc-shaped sliders. In other words, when the more numerous next-stage arc-shaped sliders slide relative to the arc-shaped grooves, their end face contours also change accordingly, thereby facilitating the clamping of pre-embedded sleeves with different pipe diameters and shapes.

[0045] The rubber clamping block 35 is connected to the arc-shaped slider at the end and is used to abut against the pre-embedded sleeve through the beam. Under the action of the arc-shaped sliders at each level, the rubber clamping block 35 forms a shape corresponding to the outer contour surface of the pre-embedded sleeve through the beam, thereby clamping the outer contour surface of the pre-embedded sleeve through the beam at multiple points. When the two opposing clamping components are respectively pressed against the pre-embedded sleeve through the beam, the friction between the arc-shaped sliders at each level can be increased, thereby ensuring the stability during the clamping process.

[0046] The fixing device for pre-embedded sleeves in beams provided in this embodiment can drive two relatively arranged clamping components to approach each other through a linear movement module 2, thereby clamping the pre-embedded sleeve. When clamping the pre-embedded sleeve, the clamping components, under the cooperation of multi-stage arc-shaped sliders, can adapt to the contour of the pre-embedded sleeve and slide relative to each other, so that the rubber clamping block 35 on the end arc-shaped slider forms a shape corresponding to the outer contour of the pre-embedded sleeve, thus fitting against the outer contour surface of the pre-embedded sleeve, which can adapt to the fixing of pre-embedded sleeves with different diameters and shapes. When the two relatively clamping components press the pre-embedded sleeve, they can maintain stable clamping of the pre-embedded sleeve under the action of large friction. It can be used with pre-embedded sleeves for round, square, and oval pipes, as well as special pipes with insulation layers, anti-corrosion coatings, and flange interfaces, significantly improving the efficiency and quality of pipe installation, maintenance, and fixing. It is especially suitable for scenarios with diverse pipe types, tight schedules, and easily damaged surfaces.

[0047] Specifically, refer to Figure 2 and Figure 3 As shown, the inner wall of the arc-shaped groove is provided with an arc-shaped protrusion, and the outer wall of the arc-shaped protrusion is provided with an arc-shaped sliding groove. The arc-shaped protrusion is inserted into the arc-shaped sliding groove and slides in cooperation with it. The arc-shaped sliding groove and the arc-shaped protrusion are used for limiting the movement.

[0048] Specifically, the number of lower-level curved sliders is N times the number of upper-level curved sliders, where N ≥ 2. In this embodiment, the number of lower-level curved sliders is twice the number of upper-level curved sliders. (Refer to...) Figure 2 and Figure 3 As shown, in this embodiment, the multi-level arc-shaped slider includes a first arc-shaped slider 31, a second arc-shaped slider 32, a third arc-shaped slider 33, and a fourth arc-shaped slider 34; the first arc-shaped slider 31 is provided with a first arc-shaped groove 311; and a first arc-shaped protrusion 312 is provided in the first arc-shaped groove 311.

[0049] The second arc-shaped slider 32 is provided with a second arc-shaped groove 321 and a second arc-shaped protrusion 322. A second arc-shaped sliding groove 324 is provided in the second arc-shaped protrusion 322, and a second arc-shaped convex strip 323 is provided in the second arc-shaped groove 321. The second arc-shaped protrusion 322 is slidably engaged with the first arc-shaped groove 311. The first arc-shaped convex strip 312 is slidably engaged with the second arc-shaped groove 321.

[0050] The third arc-shaped slider 33 is provided with a third arc-shaped groove 331 and a third arc-shaped protrusion 332. A third arc-shaped sliding groove 334 is provided in the third arc-shaped protrusion 332, and a third arc-shaped convex strip 333 is provided in the third arc-shaped groove 331. The third arc-shaped protrusion 332 is slidably engaged with the second arc-shaped groove 321. The second arc-shaped convex strip 323 is slidably engaged with the third arc-shaped sliding groove 334.

[0051] The fourth arc-shaped slider 34 is provided with a fourth arc-shaped protrusion 341, and a fourth arc-shaped groove 342 is provided at the fourth arc-shaped protrusion 341; the fourth arc-shaped protrusion 341 is slidably engaged with the third arc-shaped groove 331, and the third arc-shaped convex strip 333 is slidably engaged with the fourth arc-shaped groove 342.

[0052] In this embodiment, a total of four levels of arc-shaped sliders are provided. In other embodiments, arc-shaped sliders with different levels can also be provided.

[0053] It should be noted that the arc-shaped slider can adopt a split structure, which is divided into a semi-circular slider and an extension frame. The arc-shaped protrusion is located on the semi-circular slider, and the arc-shaped groove is set on the extension frame. The semi-circular slider and the extension frame are connected to each other by adhesive, bolt, or other connection methods.

[0054] Specifically, the two clamping components are divided into a first clamping component 3 and a second clamping component 4; the first clamping component 3 is movably connected to the linear motion module 2, and is driven by the linear motion module 2 to move toward or away from the second clamping component 4; the second clamping component 4 is fixedly connected to the linear motion module 2 and remains stationary.

[0055] Specifically, the linear motion module 2 includes a connecting base 21, a sliding block 22, a moving rod 23, a drive motor 24, and a fixed base 25. The moving rod 23 is rotatably mounted between the connecting base 21 and the fixed base 25. The sliding block 22 is connected to the moving rod 23, and the drive motor 24 is connected to the moving rod 23. The drive motor 24 drives the moving rod 23 to rotate, thereby moving the sliding block 22. In this embodiment, the moving rod 23 can be a lead screw or a threaded rod. The drive motor 24 drives the moving rod 23 to rotate, thereby moving the sliding block 22. It should be noted that a guide rod is also provided in this embodiment, and the sliding block 22 is movably connected to the guide rod.

[0056] Specifically, the first clamping component 3 is mounted on the sliding block 22 and moves with the sliding block 22; the second clamping component 4 is mounted on the fixed base 25 and remains stationary.

[0057] Specifically, the first clamping assembly 3 is rotatably mounted on the sliding block 22 via a rotating shaft 36; the axis of the rotating shaft 36 is perpendicular to the moving rod 23 and the through-beam embedded sleeve, respectively. A certain gap is reserved between the first arc-shaped slider 31 of the first clamping assembly 3 and the sliding block 22, so that the side of the first arc-shaped slider 31 is rotatably connected to the sliding block 22 via the rotating shaft 36, thereby automatically fine-tuning the angle of the first clamping assembly 3 to adapt to the contour of the embedded sleeve during clamping, resulting in a tighter fit.

[0058] The rubber clamping block 35 is connected to the arc-shaped slider at the end via a rotating shaft 37; the axis of the rotating shaft 37 is parallel to the pre-embedded sleeve through the beam. In this embodiment, two rubber clamping blocks 35 are rotatably connected to each fourth arc-shaped slider 34 via the rotating shaft 37, so that the rubber clamping blocks 35 can also rotate according to the outer contour of the pre-embedded sleeve, thereby making the fit tighter.

[0059] Specifically, the connecting frame 1 includes a fixed base 11 and a connecting plate 12. The connecting seat 21 is mounted on the fixed base 11, and the connecting plate 12 connects the two fixed bases 11. A mounting base 41 is also installed below the second clamping assembly 4, and the two second clamping assemblies 4 are connected by a support plate 42. This allows the two sets of linear motion modules 2 and their corresponding clamping assemblies to form a single integrated structure.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
