Description

Technical Field

[0001] This utility model relates to the field of boom installation technology, specifically a boom installation and fixing tool. Background Technology

[0002] A hanger is a vertical or inclined rod-shaped load-bearing structure used to suspend and support ceilings, pipelines, equipment, and other components. Its core function is to transfer the load-bearing capacity of the upper structure (such as floor slabs and beams) to the decorative components below that need to be fixed, while ensuring the stability, flatness, and safety of the decorative system. It is widely used in key aspects such as ceiling projects and electromechanical pipeline installation, and is the core load-bearing medium connecting the "upper structure" and "lower decorative components" in decoration.

[0003] Traditional ceiling, duct, and cable tray installation typically involves workers standing on ladders or work platforms, drilling holes in the ceiling, gently hammering expansion bolts into the holes, and then tightening them gradually with wrenches or pliers. However, the spacing between suspension rods is usually about 1 meter, requiring constant relocation for each installation. This necessitates constantly moving the work platform, which is slow, inefficient, and potentially dangerous. Furthermore, the rods can tilt when struck during installation, affecting the overall quality of the work. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a tool for installing and fixing a hanger rod, so as to solve the technical problems of difficulty in installation and easy tilting of the hanger rod.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a boom installation and fixing tool, comprising a bolt sleeve for fitting expansion bolts, the bolt sleeve being fitted inside an extension rod, a limiting block being fixedly connected to the outer wall of the bolt sleeve, a limiting groove being formed on the side wall of the extension rod for cooperating with the limiting block, a positioning sleeve being fitted over the extension rod, a positioning plate being fixedly connected to the top of the positioning sleeve, a plurality of positioning grooves being formed on the inner wall of the positioning sleeve, a spring plate being fixedly connected to the outer wall of the extension rod for cooperating with the positioning grooves, a pad being fixedly connected to the bottom end of the extension rod, and handles being symmetrically arranged on the side wall of the bottom end of the extension rod.

[0006] By adopting the above technical solution, workers can first directly align the expansion bolts with the installation position on the roof using the extension rod. By pushing the positioning sleeve upwards, the positioning plate can be directly made to fit against the roof surface, ensuring the verticality of the extension rod and thus preventing the hanger from tilting and affecting the construction quality.

[0007] Furthermore, a lifting rod is fixedly connected to the bottom end of the expansion bolt, and the lifting rod is inserted into the bolt sleeve.

[0008] By adopting the above technical solution, the bottom end of the expansion bolt is fixedly connected to the hanger rod, and the hanger rod is inserted into the bolt sleeve. This design realizes the tight connection and integrated installation of the hanger rod and the expansion bolt, so that the positioning and installation of the hanger rod can be completed at the same time as the installation of the expansion bolt, without the need for additional connection operations between the hanger rod and the bolt.

[0009] Furthermore, the extension rod is a cylindrical structure, and a boss for limiting the downward sliding of the bolt sleeve is fixedly connected to the inner wall of the extension rod.

[0010] By adopting the above technical solution, a boss is fixedly connected on the inner wall of the extension rod to restrict the downward sliding of the bolt sleeve. Compared with other shapes, the cylindrical extension rod has better uniform force distribution and structural stability, and can better withstand the external force applied during installation. It is not easy to deform or be damaged, and provides a stable installation space for the bolt sleeve, preventing the bolt sleeve from sliding downward when the extension rod is struck, so that the expansion bolt cannot be driven into the installation hole in the roof.

[0011] Furthermore, the top of the limiting groove is provided with an opening to facilitate the passage of the limiting block.

[0012] By adopting the above technical solution, the installation of the bolt sleeve is facilitated and the assembly process of the bolt sleeve and the extension rod is simplified. When assembling the tool, the operator only needs to align the limiting block on the outer wall of the bolt sleeve with the opening at the top of the limiting groove to easily put the bolt sleeve into the extension rod.

[0013] Furthermore, the top of the positioning plate is attached to the roof surface.

[0014] By adopting the above technical solution, it is clear that the top of the positioning plate is in contact with the roof surface. This design allows the positioning sleeve to be accurately positioned with the roof surface as a reference during installation, and the positioning plate ensures the verticality of the hanger.

[0015] Furthermore, a slot for placing a spring plate is provided on the outer side wall of the extension rod.

[0016] By adopting the above technical solution, a working space is provided for the spring plate, ensuring that the spring plate can be disengaged from the positioning slot.

[0017] Furthermore, the spring plate is an arc plate, the positioning groove is a semi-circular groove, and the arc surface of the spring plate and the positioning groove cooperate with each other.

[0018] By adopting the above technical solution, the spring plate can be more easily inserted into or removed from the positioning groove, reducing friction and jamming between the two, making it more convenient and effortless for operators to adjust the length of the extension rod, and reducing the difficulty of operation.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model increases the worker's working radius through the cooperation between the extension rod, bolt sleeve, pad block and boss, allowing workers to install expansion bolts on the ground without the need for scaffolding, which facilitates installation and increases work efficiency;

[0021] 2. This utility model, through the cooperation of positioning sleeve, positioning plate, positioning groove and spring plate, ensures the verticality of the extension rod during installation, thereby ensuring the verticality of the suspension rod and expansion bolt, and ensuring construction quality.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] In this embodiment:

[0030] A tool for installing and fixing a hanger rod, such as Figure 1-5As shown, the device includes a bolt sleeve 1 for fitting expansion bolts 2. The inner wall of the bolt sleeve 1 has an internal hexagonal groove for engaging with the nut on the expansion bolt 2. The bolt sleeve 1 is fitted inside the extension rod 3, with its outer wall fitting against the inner wall of the extension rod 3. A limit block 4 is fixedly connected to the outer wall of the bolt sleeve 1. A limit groove 5 is formed on the side wall of the extension rod 3 for engaging with the limit block 4. The engagement of the limit block 4 and the limit groove 5 prevents the bolt sleeve 1 from rotating out of sync with the extension rod 3 when it rotates. A positioning sleeve 6 is fitted over the extension rod 3, with the outer wall of the extension rod 3 fitting against the inner wall of the positioning sleeve 6. The positioning sleeve 6 is fitted with a positioning plate 7 fixedly connected to its top end. The positioning plate 7 and the positioning sleeve 6 are perpendicular to each other. Multiple positioning grooves 8 are opened on the inner wall of the positioning sleeve 6. The positioning grooves 8 are evenly opened on the inner wall of the positioning sleeve 6. A spring plate 9 is fixedly connected to the outer wall of the extension rod 3 to cooperate with the positioning grooves 8. It cooperates with the positioning grooves 8 to prevent the positioning sleeve 6 from sliding up and down relative to the positioning rod. A pad block 10 is fixedly connected to the bottom end of the extension rod 3 to facilitate workers from damaging the extension rod 3 when hitting it. Handles 11 are symmetrically arranged on the side wall of the bottom end of the extension rod 3. The handles 11 can facilitate workers to rotate the extension rod 3.

[0031] See Figure 4 The bottom end of the expansion bolt 2 is fixedly connected to the hanger rod 12. The connection between the expansion bolt 2 and the hanger rod 12 is by welding or thread connection to ensure that the connection between the two is firm and not easy to loosen. The hanger rod 12 is inserted into the bolt sleeve 1. The bolt sleeve 1 has an installation hole at the axial position. The outer wall of the hanger rod 12 fits tightly with the inner wall of the installation hole to achieve stable positioning of the hanger rod 12.

[0032] See Figure 4 The extension rod 3 is a cylindrical structure made of metal, which has good compressive and deformation resistance and can withstand external forces during installation. A boss 13 is fixedly connected to the inner wall of the extension rod 3 to limit the downward sliding of the bolt sleeve 1. It is fixed to a designated position on the inner wall of the extension rod 3 by welding or integral molding. The top surface of the boss 13 is a flat support surface. When the bolt sleeve 1 slides downward in the extension rod 3, the bottom end of the bolt sleeve 1 will contact the top surface of the boss 13. The boss 13 prevents the bolt sleeve 1 from sliding down further through its own structure, thereby achieving axial limit of the bolt sleeve 1.

[0033] See Figure 3 , Figure 4 The top of the limiting groove 5 has an opening 14 for the limiting block 4 to pass through. The size of the opening 14 is slightly larger than the size of the limiting block 4, and the opening 14 and the limiting groove 5 are integrally formed. The shape of the opening 14 is adapted to the cross-sectional shape of the limiting block 4, which facilitates assembly.

[0034] See Figure 4The top of the positioning plate 7 is attached to the roof surface 16. By attaching to the roof surface 16, the verticality of the positioning sleeve 6 to the roof surface 16 is ensured, thereby ensuring the verticality between the extension rod 3, the hanging rod 12, the expansion bolt 2 and the roof surface 16.

[0035] See Figure 4 An insertion groove 15 for placing the spring plate 9 is provided on the outer side wall of the extension rod 3, providing working space for the spring plate 9 so that the spring plate 9 can be disengaged from the positioning groove 8, thereby facilitating the sliding of the positioning sleeve 6.

[0036] See Figure 4 The spring plate 9 is an arc plate, and the positioning groove 8 is a semi-circular groove. The spring plate 9 is made of elastic metal material, and its arc radius is adapted to the outer wall radius of the extension rod 3, ensuring that the spring plate 9 can fit tightly in the placement groove 15 on the outer wall of the extension rod 3. The arc surface of the spring plate 9 and the positioning groove 8 cooperate with each other, and the arc radius of the semi-circular groove matches the arc surface radius of the spring plate 9. The arc surface of the spring plate 9 can be completely embedded in the semi-circular groove to achieve a tight fit between the two.

[0037] The implementation principle of this embodiment is as follows: First, align the limiting block 4 on the side wall of the bolt sleeve 1, which is compatible with the expansion bolt 2 at the construction site, with the opening 14 of the limiting groove 5. Place the bolt sleeve 1 inside the extension rod 3, with the bottom surface of the bolt sleeve 1 abutting against the boss 13. Then, place the expansion bolt 2 inside the bolt sleeve 1, and align the expansion bolt 2 with the pre-drilled mounting hole on the roof surface 16. Then, the worker pushes the positioning sleeve 6 upwards, causing the positioning plate 7 to abut against the roof surface 16. Finally, by tapping the pad 10, the pad 10 transmits the force to the expansion bolt through the extension rod 3. 2. The expansion bolt 2 is hammered into the mounting hole. During this process, the extension plate will slide upward relative to the positioning sleeve 6, and the spring plate 9 will continuously disengage from the positioning groove 8 of the next layer. As the extension rod 3 slides upward and engages with the positioning groove 8 of the previous layer, it restricts the downward sliding of the extension rod 3 and prevents the bolt sleeve 1 from disengaging from the expansion bolt 2. Finally, hold the positioning sleeve 6 and rotate the extension rod 3 through the handle 11. The extension rod 3 drives the bolt sleeve 1 to rotate, and the bolt sleeve 1 drives the nut on the expansion bolt 2 to rotate until the tail of the expansion bolt 2 expands and is fixed.
